Section B tells you exactly where to look for low-sodium foods. Here are examples of how your meals could work out (click for a more detailed example). 

LOW  HIGH  (Milligrams of sodium)
395     4,345   TOTAL 
  75          75    Egg or egg white
  35          35    Milk, 2 ounces for cereal

B. Know where to look. Look for the foods below. All these are far better than the FDA goals.

1. Bread with 0 sodium per slice is nationally available at Publix, Sprouts, Trader Joe's, Whole Foods, and many independent stores (from "Ezekiel/Food for Life Low Sodium"). Trader Joe's also sells its own brand. More 0-sodium bread is available from "Vermont Sodium-Free," and some loaves from Manna Organics have 3-13 mg per slice. Corn tortillas usually have 10 mg each. Other breads, bagels, muffins, and wheat tortillas are high in sodium, 150-300 mg. For your own baking, there are low sodium baking powders.
2. Oatmeal, shredded wheat, Wheatena, Cream of Wheat (1 or 10 minute, not 2.5), Cream of Rice, puffed wheat, puffed rice, and some specialized cereals have no or low sodium. 
3. Soups with no salt or "no salt added" can be found at Whole Foods or online, from Health Valley and others. Zero sodium bouillon is widely available from Herb Ox (Hormel) and Wyler's (Heinz).
4. Peanut butter, butter and popcorn are sold without salt in most stores.
5. Unprocessed vegetables, nuts and fruit are naturally low in sodium, 0-80 mg, but processors add a lot, and artichokes, chard and turnips are high (detailed list).
6. Unprocessed meat, fish, fowl are low in sodium: 50-75 mg per serving. Other processed meats are much higher. Stores may inject brine even in raw meat, so check the label. For example different versions of Boar's Head Turkey range from 55 mg to 700 mg sodium per 2 ounces.
7. Canned beans with "no salt added" can be found at Whole Foods or online, from Eden and others, 35-65 mg. Tofu and tempeh have 0-10 mg. Dried beans with low salt are in most stores.
8. Most Swiss cheese is low: 10-75 mg per ounce, (Boar's Head "no salt added" has 10 mg.) Check the label. Other cheeses are high.
9. Cottage cheese is available with "no salt added" (20-75 mg per half cup) from a few chains: Friendship (East coast), Giant/Martins (MD, NJ, NY, OH, PA, VA, WV), Giant Eagle (MD, OH, PA, WV), Hood/Crowley/Axelrod (New England, NY), Lucerne, (West, mid-Atlantic, TX), Shopright (CT, NJ, NY), Stop+Shop (CT, MA, NJ, NY, RI), Western (ON). Other cottage cheeses have 300-540 mg. USDA says cottage cheese exists with 15 mg per half cup (112g), and the lowest I have found is 20 mg (18 per 100g) from Western in Ontario.
10. Yogurt varies from 45-190 mg per serving. Check the label. Usually the lowest are Fage, Oikos, Yoplait Greek, Dannon nonfat and Stonyfield nonfat.
11. Sodium+Calcium+Protein in Milk alternatives, per 8 ounces (240 ml):
    5 mg       40 mg     12 g      EdenSoy unsweetened
    5              300           4         Hemp Dream 
    5                40           1         Rice Dream-Horchata-cinnamon
    20            300           4         Oat Dream
    30              40           9         WestSoy unsweetened (made from soy, even their almond flavor)
    30-35      350            4         Kidz Dream (soy)
    70           300            7         Silk unsweetened (soy)
    80           300            5         Flax milk from GoodKarma
    85           100            0         Cashew milk from SO Delicious
    95           100            5         Almond+Plus unsweetened from SO Delicious
    90/110    300            1         Almond milk from PC and Earth's Own (both Canadian)
    105         276            8         Cow's milk (USDA)
    110         300            2         Quinoa milk
    Most other alternatives have more sodium, like Ensure (280), protein shakes (150-300), soy milk (100-220), almond milk (150-190)
12. Eggs and alternatives (made from egg whites) have 70-100 mg.
13. Flavor without sodium comes from onions, lemon juice, vinegars, wine, powdered mustard, ground pepper, other spices, and some commercial sauces or here. The only pepper sauces without salt are from Alberto's, Island Treasure, and Trader Joe's.
14. Packaged foods: hundreds with no salt and low salt are at  HealthyHeartMarket  and  LowSaltFoods. Their founders both had congestive heart failure, took seriously their need to reduce salt, and found foods to eat.
15. RECIPES: Add the sodium in your ingredients. There are low sodium baking powders. Each quarter teaspoon of salt in a recipe has 600 mg of sodium. If your pinch of salt has about 50 individual grains, it has 1 mg of sodium. If your pinch is a sixteenth of a teaspoon, it has 150 mg and 8,000 grains. Use small pinches or none.
16. OTHER NUTRIENTS - The Institute of Medicine has detailed nutrient recommendations for men and women at different ages, which we have organized by age group in the "RDA" tab of our menu spreadsheet. Food labels showing "% DV" are based on older FDA daily values for adults, so they are only an approximate guide to the latest research. (There are also FDA values for infants, pregnant and lactating women. The various diet standards are color-coded and compared in the RDA tab of our spreadsheet. Another spreadsheet shows FDA goals for sodium in specific foods, designed to help people reach lower daily totals.) Potassium is important (beans, fruits, squashes, tomatoes), since most multivitamin/mineral pills have only 2% of your daily need, a banana has 10%, and most published diets are short of potassium. The detailed example in section A has good levels of calories, sodium, potassium, calcium and iron. The example also has far more beta-carotene than you need, which is not harmful, though Vitamin A itself would be. Your body converts what it needs to vitamin A and discards the rest. "Beta-carotene is not toxic even at high levels of intake."
    
17. The sample diet in section A is at a free site, MyFitnessPal, which lets you look up most foods, including brand names. Try multiple wordings, like "no salt added." They do not have a compare  button, but if you log in you can add any number of foods to a meal (free login, supported by ads). Then it will compare their nutrients, like the sample diet. You can copy that list to your own account by logging in, going back to that page, clicking "Quick tools - Copy to today" and changing the diet as you wish. Remember the date of your list, and you can go back to the list and add to it. "Diary settings" lets you choose any 5 nutrients which are then displayed on your pages. Some nutrients are shown as % of FDA daily values: calcium 1,000 mg, iron 18 mg, vitamin A 5,000 IU, and vitamin C 60 mg. 
18. Iodine: the sample diet includes Nori seaweed for iodine, though dairy products have some iodine too. When you stop adding table salt, you need to be sure you get enough iodine.
19. Water from a water softener averaged 278 mg/liter in an area where city water had 110 mg/liter. Nationally sodium in city water varies 5-195 mg/liter, with an average of 43, and bottled or distilled spring water is 0-15 mg/liter, but check the website given on label. Bottled mineral water is much higher in sodium. 
20. STORE LABELS - Besides a "Nutrition Facts" label, low salt foods in stores may have the following labels:

• "Very low sodium" means less than 35 mg sodium per serving.

• "No salt added" means the processor did not add any; the result is usually under 50 mg.
• "Low sodium" means less than 130 mg.
• "Reduced sodium" is useless. It means 25% less than regular versions and can still be hundreds of milligrams.
• I recommended (you can too) that the 2015 Dietary Guidelines Committee establish an optional graphic for use on labels to show sodium content, just as appliance labels show energy use.

21.  RESTAURANTS - When you go to restaurant chains, take this bar graph of outstanding food at each chain. Ask for their list of salt content, or look first at New York's list of many national chains, which you can sort to find low sodium. You can also check the chains' websites as I did. 

• The bar graph shows an entree at each chain with the lowest sodium, saturated fat and sugar per gram of protein. These are usually eggs or grilled chicken. The restaurants have other foods with low sodium, fat and sugar, but without much protein and other useful nutrients. The lowest are at PF Chang's, Bob Evans, Long John Silver, and Denny's.
• Restaurant oatmeal has low sodium (5-45) at Bob Evans, IHOP, Jamba Juice and Chik-Fil-A, but is cooked with 100-470 mg per serving at other chains. Shredded wheat is reliably low in salt at restaurants.

• Restaurant smoothies have low sodium (10-50) at Denny's, Jamba Juice and McDonald's, but not elsewhere. Read the nutrition chart when ordering: "Classic Strawberry Surfrider" at Jamba Juice has 10 mg in a medium smoothie, but the "Make it Light" and "Wild" versions have 125-160.

• Golden Corral - wide range of fruits, vegetables, and pasta with 0 sodium, many more from 5-50. Eggs 60-70 mg each, BBQ pork and turkey at 100-130 per 3 ounces. You'll need to print our sorted list and take it with you, to avoid all the other high sodium choices. They do not list oatmeal or smoothies.
• Denny's (or xls) - Corn, red onion, tomato, lettuce, fruit have 0-7 mg sodium. Grits+margarine 15. Broccoli or spinach 20-22. Smoothies 30-45. Avocado, steamed zucchini, grilled onions, mushrooms, pico de gallo 40-67. Yogurt 100. 1 egg or egg white 118. Garden salad 150. Oatmeal 220. Chicken strips+buffalo sauce 3,450.

• McDonald's - apple slices 0, side salad 10, smoothies 40-50, yogurt 40-70, sundaes 85-170, oatmeal 115, apple pie 170, four McNuggets 360, hamburger 480, Egg McMuffin 740, Big Mac 970, 1/4 pounder+bacon+cheese 1,440. The salad is without dressing, since even their simplest vinegar dressing, Newman's balsamic vinegar, has 420 mg sodium. Newman's company should be ashamed.
• Panera - fruit cup 15, smoothies 75-105, classic cafe salad 140, oatmeal 160, turkey+avocado+BLT+sourdough 980 (lowest full sandwich), bacon+turkey on XL tomato basil 2,990.
• Starbucks - fruit blend 0, greek yogurt+honey 75, greek yogurt+berries 115, choc meringue cookie 115, oatmeal 125 (they wrote to me that the zero shown in their flyer, Nutritionix, and New York's Menustat is an error), smoothies 120-160 (which is shown on their flyer; they show 0 on website, Nutritionix, and Menustat; they wrote to me insisting on 0, though the milk in their recipe would always contribute substantial sodium, so it might be wise to mistrust their other numbers too), large Frappuccino java chip 340, cheese+fruit box 470, protein egg+cheese box 470, turkey+swiss sandwich 1,140.

• Subway - Veggie Delite Salad 80, roast chicken salad 280, Veggie Delite 6" sandwich 280, roast chicken 6" sandwich 610 (lowest sandwiches)

• Suggestions for other foods from New York and LowSaltFoods, but see note 22 below. 
• Non-chain restaurants need other approaches.

22.  REFERENCES include:

• Menustat, New York, compares restaurant chains easily; sort and download. See a graph of outstanding food at each chain. Check with restaurant website if you eat there often. For example New York shows 4 mg sodium in grilled chicken salad from Bojangles, whose website says it has 530mg. They show 0 sodium in Starbucks oatmeal and smoothies, both of which are 125 or more. And you must read carefully; New York shows low sodium in PF Chang's Steamed Gluten-Free Buddha Feast; the company website does show 50 mg in the gluten-free, but 300 in the regular, and 3,440 stir fried.
• MegaHeart, compare non-branded foods easily.
• USDA, look up or sort foods by sodium or other nutrients, or download the database; few brand names. There is extra detail on amino acids and sugars at EatThisMuch.
• MyFitnessPal, look up branded and non-branded foods; add up a day's eating. Many items were entered by the public, often with missing data, so double-check with food labels or USDA where possible.
• HealthyHeartMarket, find low salt brands
• LowSaltFoods find low salt brands
• Globe1234 list of foods with good Fiber, Protein, Calcium, Potassium, compared to their Saturated Fat, Calories, Sugar, and Sodium
• Nutritionix look up branded and non-branded foods. They have some (all?) of the same mistakes as Menustat above: Starbucks oatmeal+smoothies, Bojangles grilled chicken salad, all listed with far less sodium than they have.

C. Health organizations' advice is to control salt in the diet to avoid high blood pressure. The advice usually omits crucial information:

1. Is salt OK for the large numbers of people whose blood pressure is low or is controlled by medicine? No, it leaches calcium from the body, causing broken bones and other harm; see D below.
2. Where can we buy low salt foods? See B above.
3. Do people eating varied healthy diets need to add up all their salt from dozens of labels to watch their total consumption? Yes, start with your most common 5-10 foods, writing sodium from the labels; easiest if you use MyFitnessPal which will let you see and resolve any potassium or calcium shortfall at the same time.
4. How many sandwiches, cups of soup, entrees, etc. can I have per day and keep salt under control? Plenty of "no salt added" versions; see B above.
5. What is the minimum salt needed? 180-500 mg per day; see E below
6. What is a dangerous level of salt? 1,200-2,300 mg per day; see E below.

Below is an attempt to bring some answers together.


D. Results of high sodium diet: broken bones, stroke, kidney failure, weakness.

1. NIH says "Sodium, often from salt, causes the kidneys to excrete more calcium into the urine. High concentrations of calcium in the urine combine with oxalate and phosphorus to form stones. Reducing sodium intake is preferred to reducing calcium intake."
2. An Australian study found that you excrete calcium, and your hip bones lose strength, and break more easily unless your intake of sodium is less than twice as much as the calcium you eat. So if you eat 1,000 mg calcium, you have to stay under 2,000 mg sodium. If you eat only 500 mg calcium, you have to eat less than 1,000 mg sodium to avoid hip fractures.
3. A European study found people's bones lost 12 mg calcium per day eating a diet of 4,400 mg sodium and 1,300 mg calcium. If they kept the same calcium but cut down to 1,600 mg sodium, their bones gained 90 mg calcium per day. A steady loss of 12 mg per day would deplete 3% of their skeleton in a decade, and most of the loss is at the hips, which are then more likely to break. When the same people had a more typical low calcium diet (520 mg), their bones lost 71 or 115 mg calcium per day, depending which sodium level they ate, which would deplete 18% or 29% of the skeleton in a decade. So you need both high calcium and low sodium to avoid bone loss and bone breakage. All the effort you put into eating high calcium foods is wasted if you eat high sodium foods too. None of the volunteers had high blood pressure; all were under 140/90, and their average blood pressure was 115/72.
4. Nutrition labels do not show milligrams of calcium. they show percent of 1,000 mg, so 25% means 250 mg, etc.
5. NIH says "Too much sodium in the diet may lead to:
       *   High blood pressure in some people
       *   A serious build-up of fluid in people with congestive heart failure, cirrhosis, or kidney disease"
6. US Dietary Guidelines 2010 say "association between sodium intake and blood pressure was continuous and without a threshold... blood pressure was... lowered even further when sodium was targeted to the level of 1,200 mg per day" (p.23, which is 4th page of pdf).
7. Mayo Clinic says high blood pressure in turn causes dialysis, blindness, bone loss, dementia, strokes, heart failure, etc.
8. Nutritionist Jane Brody says, "Too much salt can impair athletic performance because it draws water out of your muscle cells. For optimum muscle function during vigorous exercise, the cells should be filled with water." Otherwise "your muscles can’t contract normally and you can feel weak and tired."
9. A summary by WHO and British researchers found: 

• "In adults a reduction in sodium intake significantly reduced resting systolic blood pressure by 3.39 mm Hg (95% confidence interval 2.46 to 4.31) and resting diastolic blood pressure by 1.54 mm Hg (0.98 to 2.11). 
• When sodium intake was <2 g/day versus ≥ 2 g/day [below and above 2,000mg/day], systolic blood pressure was reduced by 3.47 mm Hg (0.76 to 6.18) and diastolic blood pressure by 1.81 mm Hg (0.54 to 3.08).
• Decreased sodium intake had no significant adverse effect on blood lipids, catecholamine levels, or renal function in adults (P>0.05). 
• There were insufficient randomised controlled trials to assess the effects of reduced sodium intake on mortality and morbidity. 
• The associations in cohort studies between sodium intake and all cause mortality, incident fatal and non-fatal cardiovascular disease, and coronary heart disease were non-significant (P>0.05). 
• Increased sodium intake was associated with an increased risk of stroke (risk ratio 1.24, 95% confidence interval 1.08 to 1.43), stroke mortality (1.63, 1.27 to 2.10), and coronary heart disease mortality (1.32, 1.13 to 1.53)." 
• There are minority views that the lack of effect on all cause mortality is important.

E. How much sodium is OK?

1. NIH says "Healthy adults should limit sodium intake to 2,300 mg per day. Adults with high blood pressure should have no more than 1,500 mg per day. Those with congestive heart failure, liver cirrhosis, and kidney disease may need much lower amounts."
2. CDC says, "People who should limit their sodium to 1,500 mg a day are:
   • People who are 51 years or older
   • African Americans
   • People with high blood pressure
   • People with diabetes
   • People with chronic kidney disease"
3. American Heart Association says, "Under conditions of maximal adaptation and without sweating, the minimum amount of sodium required to replace losses is estimated to be no more than 180 mg per day." (p.4)
4. WHO says, "Although the minimum intake level necessary for proper bodily function is not well defined, it is estimated to be as little as 200–500 mg/day" (p.5)
5. Harvard Health Letter says, "Paleolithic diet delivered... well under 700 mg of sodium... The average American consumes... between 2,500 and 7,500 mg of sodium, much of it hidden in processed or prepared foods. That's far more than the scant 200 mg a day the body needs."
6. USDA says "average intake of sodium for all Americans ages 2 years and older is approximately 3,400 mg per day."
7. A CDC study says 99% of people aged 20 or older eat over 1,500 mg sodium per day and 89% eat over 2,300. The study also says 99% of people eat less than the daily requirement of 4,700 mg of potassium.
8. The USDA and Health+Human Services in 2016, under heavy pressure from food companies for higher limits, recommend staying under 2,300 mg per day.
9. Morton says there are 10,000,000 grains of salt in a pound, which means 55 grains of salt per milligram of sodium.
10. CDC converts the measurements in different studies as follows:

• Sodium chloride, commonly known as salt, consists of 40 percent sodium and 60 percent chloride. 
• One level teaspoon of salt contains approximately 2,300 mg of sodium.
• To convert mg of sodium to mg of salt, multiply the mg of sodium by 2.5.
• To convert mmol of sodium to mg of sodium, multiply mmol of sodium by 23.
• To convert mmol of sodium to mg of sodium chloride, multiply mmol of sodium by 58.5.

F. Institutions:

1. Even nursing homes, hospitals and assisted living usually serve too much salt.
2. If they say they never cook with salt, do they use high-salt ingredients?
3. Ask if they if they use zero-sodium bouillon (commercially available from Wyler, Herb-Ox), or high-sodium chicken stock as a base for soup?
4. Ask if they use no-salt bread, butter, cheese, peanut butter, cottage cheese?
5. When you are looking for a nursing home, salt could be one of your criteria. 
6. Find what brands of ingredients they use for soups, breads, cheeses, etc. (often institutional brands with poor labeling, but it is worth looking on their websites).
7. Look up salt content of these brands, and add up a day's diet.
8. If nevertheless you use a nursing home or hospital that provides salty food, take your own low salt food, and avoid their soups and sauces. 
9. When enough patients do this, they will start cooking without salty ingredients.

G. Published Diets:

Most published diets have too much sodium, too little potassium, calcium and iron, according to Diet guidelines. The 4 sample menus below all have enough of the nutrients shown.
 
DAILY MENUS   CALORIES   SODIUM   POTASSIUM   CALCIUM   IRON
Globe1234                1,500            420                 5,300            1,000         18 
Raw                           2,440            846               11,401            1,660         24 
"What I Eat"              3,104         1,404                 6,050            1,070         22
NIH Low Salt #6        1,935         1,472                 4,710            1,214

A list of 40 other sample menus and US dietary standards shows how the recommended diets fall short of the standards, which makes it hard for people to follow the standards. A spreadsheet version of the list also shows how many calories we need, according to our age and height. 

Aside from one NIH diet, #6 listed above, all other diets from NIH, USDA, and the National Institute on Aging fail the standards, with excess sodium or shortfalls in other nutrients. US News and World Report lists 32 other diets, showing some of the same nutrients above; none of those diets has appropriate sodium (below 1,500) and potassium (above 4,700).  

There is a software website, EatThisMuch, (or another version Swole.me)which will generate diets with your choice of calories, sodium, protein, fiber, carbohydrate, fat, cholesterol. It is very helpful and creative, though even that site usually does not give enough calcium, potassium or other micronutrients.

Gerber offers a menu planner for children up to 4 years old. Sometimes a screen asks whether you are a health care professional (undefined); "no" takes you away from the planner, "yes" lets you continue. Click "Generate" for a week of menus, with a mix of Gerber products and unbranded foods. Then click in the "Nutrition Details" box (upper right) to see daily totals of sodium and other nutrients. Finally click  the column heading for each Day to see nutrients of each food. For example they averaged 1,000 mg/day sodium for a 4-year-old, but suggested one day withe 1,500 mg. Clicking on that day showed they included 724 mg from a sloppy Joe sandwich, 241 from a waffle and 164 from a tablespoon of Ranch dressing, so it wouldn't be hard to cut back.

Medscape has a scary and pointed survey of how doctors decide what care to give:

• a third pull the plug when they want to, even if the family wants further care
• a quarter pull the plug when the family asks, even if the doctor thinks the patient can recover
• a quarter pull the plug on a newborn if they think s/he will have a "terrible" quality of life
• a tenth under-treat pain since they fear trouble from the Drug Enforcement Agency or patient addiction
  
• a tenth deny treatment when insurance won't cover it, even when the patient can pay privately
  

medscape.com/features/slideshow/public/ethics2014-part1?src=wnl_edit_specol
They surveyed 17,000 US doctors and 4,000 European doctors.

Geriatricians say that "state statutes sharply restrict the circumstances in which clinicians may forgo life-sustaining treatment on the basis of a living will... Living will laws tend to assume that preferences expressed in advance may be changed in the event of dementia..."

A nationally representative survey in the US found that two thirds of people had advance directives before they died, but confirmed they were not always followed. Among incapacitated patients who had left instructions:

• Only 10 patients wanted all care possible; 5 got it but 5 did not.
• 425 patients did not want all care possible; 395 got what they requested, but 30 got full care.
• 14% of representatives said problems came up in trying to follow the written instructions.

They surveyed next of kin for 3,764 people over 60 who died in 2000-2006 (random sample which represented 12 million deaths). Some advance directives named a representative, some gave instructions, some did both.

An earlier study tracked patients in one nursing home from 1986-87. The researchers asked mentally competent patients who agreed to participate about their care preferences, typed individual statements, read them back, changed further if needed, then put the signed statement in the nursing home file, with another copy in a prominent envelope in the file, for transfer to the hospital if needed. 

• 18 patients got less complete care than they instructed.
• 6 patients got more aggressive care than they instructed.
• The envelope of patient instructions was given to the hospital in only 24 of 71 hospitalizations. 

To get your wishes respected, consider asking your lawyer (see above for a discussion of lawyers) to write a letter confirming your wishes, and noting that while the patient can change wishes at any time, repeated inquiries by doctors when the patient is sick would be harassment.

Family members do not always follow instructions. Public radio quotes New Hampshire's "Long Term Care Ombudsman - basically the complaint department for New Hampshire nursing homes. He says what’s directed in the form doesn’t always get carried out. 'Younger folks take it upon themselves to say, "You know, I know Dad wants this, but I think this would be better for them." Well, that’s not their job.' "

Pregnant women's directives on withdrawing life support have limited or no effect under many state laws.

In a  study of deaths in British hospitals from July-September 2015, 4% of patients had advance directives, and 91% were used. DNR orders were discussed with 36% of patients and 81% of patients' representatives. For 16% of patients there was no reason given why a discussion did not take place:

• "Where there was an advance care plan, the team took the contents into account when making decisions (91%) and it was reviewed (79%); however only 4% (415/9302) of patients had documented evidence of an advance care plan made prior to admission to hospital.
• "A do not attempt cardiopulmonary resuscitation (DNACPR) order was in place for 94% (8711/9302) of patients’ notes at the time of death. Where sudden deaths are excluded, discussion about CPR by a senior doctor with the patient was recorded in 36% (2748/7707). Overall, for 16% (961/6072) there was no reason recorded why a discussion did not take place. Discussion about the CPR decision with the nominated person(s) important to the patient was documented in 81% of cases.
• "It was recorded that 32% of patients had opportunities to have their concerns listened to and, of these, 94% were given the opportunity to have questions answered about their concerns."

When a patient or representative disagrees with a hospital doctor's plan of care, either can appeal to the hospital's ethics committee, which has 1 or 2 people on call to listen and advise. If patients are in a hurry they need to decide whether to spend a few hours on this internal procedure or go straight to court, based on an attorney's advice. 

Loyola University has 3 free video case studies, which use actors to train ethics committee members. Loyola says the committee should get the doctor's story first, and prepare the doctor before the meeting, "prepare any health-care team members for participation in the conference." No one prepares the patient or representative. In 2 of the 3 cases the doctors get what they want by their forceful arguments. Ethics committee members' goal seems to be getting a decision made and accepted by doctor and representative. Rubin says mediation by untrained mediators subverts ethics, and adds, "it would not be unexpected to find more disagreement than consensus surfacing as difficult cases are discussed in the ethics consultation process."

The case studies never address the financial incentives everyone has: the hospital (which employs committee members) is generally paid a flat fee for each hospital stay, based on the patient's main diagnosis, but not based on the length of his/her stay, so shorter treatment saves the hospital money, and death prevents future readmission penalties. Furthermore enrollment in hospice will remove the death from the hospital's death rate, as tracked by Medicare.

In all 3 of Loyola's training videos, the representative goes into a room with 3 hospital staff, and there's no discussion of getting a second opinion from an independent doctor. The representatives are tired from care-giving. One says she's been with her mother for 30 hours. The doctors are understandably in a hurry to get back to other patients. The ICU doctor has either left the ICU for the meeting, or has stayed for a meeting after the end of her 12-hour shift, and she'll have to take the decision back to the next doctor to carry out. To avoid medical errors, representatives are advised to keep someone in the patient's room at all times, so if the representative has an ally at the hospital, that ally is probably in the patient's room. For these life and death decisions, an representative really needs an ally who's been through the process before, like a former ethics committee member, a nurse-advocate, or a lawyer.

The chair of U of Michigan Medical Center's ethics committee describes how his committee works (starts at 2:15 minutes into the video and goes to 17:15 minutes). He says that two committee members discuss the issues with doctors and representatives or patients, then post their draft report on an internal website for other committee members to post comments.

LAW

Federal law requires: "42 CFR 489.102 (a)  Hospitals, critical access hospitals, skilled nursing facilities, nursing facilities, home health agencies, providers of home health care... must maintain written policies and procedures concerning advance directives... and are required to: 
"(1)  Provide written information to such individuals concerning— 
"(i)  An individual's... right to accept or refuse medical or surgical treatment and the right to formulate, at the individual's option, advance directives... and 
"(ii)  The written policies of the provider or organization respecting the implementation of such rights...
"(4)  ...The provider must inform individuals that complaints concerning the advance directive requirements may be filed with the State survey and certification agency"
A lawyer says this rule is almost never enforced.

"But most people die in the healthcare system. Indeed, most of them die as the result of a deliberate decision to stop medical treatment that might have prolonged their life" (Pope, 2011, Widener Law Review)

When a patient enters a hospital, s/he is sick, weak and/or in pain, and has often forgotten to wear hearing aids. Hospitals may not let the representative in the room at first. At that moment an unknown doctor asks orally whether the patient wants CPR, electric shocks or a breathing tube if the heart or breathing stops. The questioning occurs even if there is an advance directive, since the patient's choice might change. Miscommunication is possible.

Hospitals and doctors have trouble talking to patients about the end of life. This section gives examples from the American Medical Association, Los Angeles. and Canada.

Six professors and doctors from the University of Chicago, Johns Hopkins, Northwestern, St Luke's-Roosevelt and Massachusetts General say (J of the Am. Geriatric Soc. 1/2013), "clinicians lack sufficient understanding of the predictors of survival after CPR to assist in such discussions."

Considering whether care is helpful or futile, AMA opposes "the concept of 'futility,' which cannot be meaningfully defined."

AMA has intricate rules for considering advance directives in "Ethics Opinion 2.037 - Medical Futility in End-of-Life Care." They expect sick patients in the hospital to negotiate for whether their wishes will be followed. AMA's background reports for this opinion show their thinking goes back to 1990 when CPR rarely succeeded. AMA says (emphasis added):

"give consideration to patient or proxy assessments of worthwhile outcome... [The] intent... should not be to prolong the dying process without benefit to the patient or to others with legitimate interests. They may also take into account community and institutional standards..."

"(1) All health care institutions… should adopt a policy on medical futility; and
"(2) Policies on medical futility should follow a due process approach. The following seven steps should be included…

"(a) …negotiate… on what constitutes futile care for the patient, and what falls within acceptable limits for the physician, family, and possibly also the institution.
"(b) Joint decision-making should occur between patient or proxy and physician to the maximum extent possible.
"(c) Attempts should be made to negotiate…
"(d) Involvement of an institutional committee such as the ethics committee should be requested if disagreements are irresolvable.
"(e) If the institutional review supports the patient’s position and the physician remains unpersuaded, transfer of care to another physician within the institution may be arranged.
"(f) If the process supports the physician’s position and the patient/proxy remains unpersuaded, transfer to another institution may be sought and, if done, should be supported by the transferring and receiving institution.
"(g) If transfer is not possible, the intervention need not be offered."

• No agreement in (g) means no treatment, which satisfies some patients, but not all.
• Appeal process in (d) is inside the hospital. Few patients know about it. Few patients know which treatments they are not offered.
• Little guidance for what a doctor may call futile in (a)
• No guidance in preamble for what is a benefit to patients: seeing another dawn, time to pray, hugs?
• 1996 Report for this Opinion specifically said for (b) "Joint decision-making at the bedside between patient or proxy and physician." At the bedside there is a huge power gap between healthy suited doctors standing, and a prone sick patient in a hospital gown. This power gap destroys "due process."
• No court asks a person to negotiate a life-changing case while sick, as required in (c).
• Every 12 hours the doctor changes, and a new negotiation may be needed; doctors cannot be identified in advance, so this AMA ethics approach offers no way to negotiate when the patient is healthy. And AMA tells patients a fib, "an advance directive, can ensure that your wishes will be honored."

Unfortunately the AMA language about futility in End-of-Life Care dates to 1990 when CPR rarely succeeded for patients with certain diseases. The 1990 Report supporting this Ethics Opinion says, 

"CPR may be withheld if, in the judgment of the treating physician, an attempt to resuscitate the patient would be futile... In a study... none of the patients with metastatic cancer or pneumonia survived until discharge from the hospital. (note 7) Among patients with renal failure, only 2% survived until discharge... Of the 63 patients with metastatic cancer, 3... none survived until discharge. In addition, of 73 patients with a diagnosis of sepsis... only one of the 73 patients survived until discharge from the hospital... 
"some physicians describe a medical treatment as futile only if the possibility of success approaches 0%, whereas others associate futility with success rates as high as 13%...
"This approach to defining futility replaces a medical assessment... with a non-medical value judgment that is made by the treating physician... This interpretation of futility is inconsistent with the principle of patient autonomy... Similar obstacles to patient autonomy are encountered when the success of CPR is judged by its ability to benefit the patient in a manner that is viewed as appropriate by the treating physician or by others...
"Once the objectives of the patient have been clearly expressed... Resuscitative efforts, under such circumstances, would be considered futile if they could not be expected to achieve the goals expressed by the informed patient... 
"In the unusual circumstance when efforts to resuscitate a patient are judged by the treating physician to be futile,... CPR may be withheld... the physician should inform the patient... also should be prepared to discuss appropriate alternatives, such as obtaining a second opinion or arranging for transfer of care to another physician." (emphasis added, AMA, 1990 Report supporting Ethics Opinion 2.22 Do-Not-Resuscitate Orders)

• AMA language about futility dates to 1990 when CPR rarely succeeded for patients with serious diseases.
• AMA respects an "informed" patient, so patients need to state their facts and sources
• AMA defines futile in terms of meeting the patient's goals
• The AMA Report advises physicians to offer a 2nd opinion or transfer of care. That offer is not  mentioned in the current ethics rules. 

An updated report in 2005 did not update the data on success of CPR.

Three professors from Columbia and Harvard recommend (JAMA 3/7/2012, emphasis added):
"Physicians should not offer CPR to the patient who will die imminently or has no chance of surviving CPR to the point of leaving the hospital."

• They do not define "imminently"
• There is no category of people who have "no chance" of surviving. In fact even people over 90 years old and people on dialysis have over 12% chance of living to leave the hospital. People in poor neighborhoods have 13% chance. Blacks have 15% chance. Heart attack survivors have 26% chance of surviving a later heart stoppage. Where should the cutoff be? How many doctors know the odds for various groups?

Except for some people with "extraordinary" values, they say, 

• "it is, in our opinion, not only ethical, but also imperative, that CPR not be offered...
• "However, the decision not to offer CPR should be disclosed to the patient or surrogate...
• "the intent is to protect the patient from harm and maximize comfort."

They recommend an appeal within the hospital, and not following the last wishes of patients who will die imminently.

A bioethicist for Mercy Health (4 hospitals in and near Philadelphia) notes (AMA  J of Ethics May 2007 emphasis added):
"If agreement is not reached between the physician or hospital and the patient or surrogate, either party may seek injunctive relief from the courts, or the patient/surrogate may file medical malpractice action... the threat of litigation alone will deter some physicians from ever invoking a futility policy... a consensus among physicians can then be submitted as evidence in legal proceedings to demonstrate that the standard of care was not breached."

• If patients and representatives/surrogates want to follow the hospital bioethicist's suggestion of injunctive relief, they need to choose a specialized lawyer. Lawyers always say to contact them before a crisis happens. Malpractice lawyers are the most common specialty with experience understanding hospitals' decisions.
  

Nine major Los Angeles hospitals and medical groups issued a press release promising "shared-decision making with patients" at the end of life. They did not release the actual guidelines, so I got them from UCLA under California's Freedom of Information Act. The guidelines cover 33 hospitals, 10,000 doctors and 7,000,000 patients.

Surprisingly, the new guidelines call many standard treatments "non-beneficial," (emphasis added in all quotes in this section) and encourage doctors not to discuss them with patients. They say: "In patients with late-stage terminal illness, use of interventions such as

• "renal dialysis
•  "intravenous feeding
•  "gastric [tube] food feeding
•  "artificial ventilation
•  "cardiopulmonary resuscitation or
•  "admission to an intensive care unit

"are generally non-beneficial and may cause an increase in pain and suffering (i.e. harm)" (footnote 5)

Problems with this Los Angeles guidance include:
(A) there is no definition of "late stage," and 
(B) "terminal illness" is so broadly defined it covers most older people: "any disease affecting one or more organs whose progression is not preventable, and commonly leads or contributes to death or manifest deterioration (mental or physical) within a predictable timeframe" (footnote 3). This definition of terminal illness covers: 

• arthritis, 
• failing ears, eyes and memory, 
• clogged or hardened arteries, 
• breathing problems, and 
• people with disabilities. 

The Los Angeles guidelines apply during "late-stage terminal illness." This appears to include:

• stage 3 cancer, heart or lung disease, or
• moderate dementia, or
• life expectancies longer than 6 months,

because "end-stage terminal illness" is defined as: "often includes, though is not limited to, 

• stage 4 disease of the heart or lungs, stage 4 cancer, or
• advanced dementia, … [and]
• life expectancy of less than 6 months" (footnote 3).

So at stage 3, or with life expectancy of 12 months, the guidelines give doctors legal cover, "not obliged to offer or provide medically non-beneficial treatment" (section 4). 

They are allowed to deny dialysis, tube feeding, CPR, ventilation or ICU, so the doctor earns Medicare rewards for saving money, and so patients don't survive to cause very expensive readmission penalties at the hospital. 

By not offering these standard treatments, doctors deny patients the choice of more time with family and friends. A single dialysis session can clean a patient's system, giving a few more days to make decisions on continuing care or to say goodbye. A single CPR has a 23% chance of success, and gives a median of 2 more years of life, in about the same state of health as before.

After a treatment is called non-beneficial California law lets a doctor be silent about it, except when a patient or representative directly instructs it be done. Then the doctor must give the treatment or offer to transfer the patient elsewhere. But patients almost never have independent advice to make such a direct instruction, so doctors are allowed to stay silent while shared decision-making and life disappear.

The Los Angeles guidelines say, "Decisions not to comply with a patient or legally recognized healthcare decision maker's request for medically non-beneficial treatment should be undertaken in accordance with California probate code sections 4734-4736" (footnote 5).

California probate code says, "4735.  A health care provider or health care institution may decline to comply with an individual health care instruction or health care decision that requires medically ineffective health care or health care contrary to generally accepted health care standards applicable to the health care provider or institution." 

Thus the effect of the new guidelines is to permit the silent denial of dialysis, tube feeding, CPR, ventilation and ICU whenever doctors want to deny them to patients with chronic illnesses.

The guidelines cover 33 hospitals, 10,000 doctors and 7,000,000 patients in southern California: 

• Cedars-Sinai - 1 hospital
• HealthCare Partners Medical Group - 600,000 managed care patients
• Huntington Hospital in Pasadena
• Kaiser Permanente Southern California - 14 hospitals, 6,000 physicians, 3,600,000 patients
• Los Angeles County–USC Medical Center | Keck School of Medicine
• MemorialCare Health System - 6 hospitals
• Olive View–UCLA Medical Center
• Providence Health and Services - 6 hospitals*
• UCLA Health System - 4 hospitals, 2,000 physicians, 2,500,000 patients

*Providence, in the list above, is a Catholic health system. Another article discusses the compatibility of Catholic teaching with the guideline above on not offering artificial feeding.

Below is a sample of some of the best research on the generally high skills of high-volume doctors. You can find older studies in their end notes, and each entry gives the newer studies which cite them.

There is also a research study on the two causes of high volume: more referrals to the best doctors, and practice makes perfect. Companion articles address training of doctors and how to find high-volume doctors.

CANCER, HEART AND ANEURYSM SURGERY

"Surgeon volume and operative mortality in the United States." Birkmeyer JD, Stukel TA, Siewers AE, Goodney PP, Wennberg DE, Lucas FL,  N Engl J Med. 2003 Nov 27;349(22):2117-27.  with comments Cited by 101 articles.

"Patients can often improve their chances of survival substantially, even at high-volume hospitals, by selecting surgeons who perform the operations frequently...

"Increasing surgeons’ volumes would require that administrators and leaders in the field of surgery actively manage the way in which selected operations are distributed within their hospitals — that is, by restricting them to a smaller number of surgeons. Although such efforts would no doubt encounter resistance, they may be more practical and less controversial than policies focusing exclusively on redistributing patients among hospitals."

Low-volume surgeons had 1 to 10 more deaths per 100 patients than high-volume surgeons. See table above.

All types of surgeons had similarly risky patients: "there were no clinically important differences in predicted mortality rates [patient risk] according to surgeon volume."

The study counted deaths within 30 days of the operation (or during the same hospital stay, even if longer than 30 days), based on 470,000 Medicare patients in 1998-99. Surgeon volume includes estimates of non-Medicare patients. These estimates can be fractions.


"Is volume related to outcome in health care? A systematic review and methodologic critique of the literature." Halm EA, Lee C, Chassin MR, Ann Intern Med. 2002 Sep 17;137(6):511-20. Cited by 160 articles.

"69% of studies of physician volume reported a statistically significant association between higher volume and better health outcomes. No study documented a statistically significant association between higher volume and worse outcomes."

"[T]he most striking differences in mortality rates between high- and low-volume surgeons were seen for pancreatic cancer, ruptured abdominal aortic aneurysm, and pediatric cardiac surgery (median differences of 3 to 14 deaths per 100 cases for the three procedures). Surgeon volume seemed to be a more important determinant of outcomes than hospital volume in the case of CABG, carotid endarterectomy, surgery for ruptured abdominal aortic aneurysm, and surgery for colorectal cancer."

"Increasing evidence shows that high-volume providers may more consistently use proven effective therapies, such as aspirin or beta-blockers in [heart attacks] or adjuvant [followup chemo, radiation, or hormones] therapy in breast cancer...

"We found a positive association between physician volume and outcome in 62% of studies with no risk adjustment, 68% of those with risk adjustment using administrative data, and 73% of investigations using clinical risk-adjustment models."

A summary article in 2007 quotes a British specialist that death rates are lowest at hospitals which treat 43 or more abdominal aortic aneurysms  per year.

HEART ATTACKS

"Relationship between annual volume of patients treated by admitting physician and mortality after acute myocardial infarction." Tu JV, Austin PC, Chan BT, JAMA. 2001 Jun 27;285(24):3116-22. Cited by 20 articles.

"Patients with AMI [heart attack] who are treated by high-volume admitting physicians are more likely to survive at 30 days and 1 year."

"The 30-day risk-adjusted mortality rate was 15.3% for physicians who treated 5 or fewer AMI cases per year (lowest quartile) compared with 11.8% for physicians who treated more than 24 AMI cases annually (highest quartile; P<.001). The 1-year risk-adjusted mortality rate was 24.2% for physicians who treated 5 or fewer AMI cases per year (lowest quartile) compared with 19.6% for physicians who treated more than 24 AMI cases annually (highest quartile; P<.001)...

"Physician volume is a well-established determinant of outcomes after invasive cardiac procedures. Previous studies have demonstrated an inverse relationship between annual surgeon volume of coronary artery bypass graft (CABG) procedures and in-hospital mortality and between annual cardiologist volume of percutaneous coronary interventions (PCIs) procedures and complication rates after the procedure. [notes 1- 3] These associations have led to development of American Heart Association/American College of Cardiology guidelines that recommend a minimum annual volume of procedures that should be performed by cardiac surgeons and invasive cardiologists...

"Physicians who treated the most patients on an annual basis had the lowest 30-day and 1-year patient mortality rates, even after adjusting for potential confounders. The impact of physician volume on outcomes of AMI [heart attack] patients was comparable with the impact of physician volume on outcomes of invasive cardiac procedures... The association between physician volume and mortality was robust and existed across physician specialties.

"The results of our study are consistent with a previous study conducted using Pennsylvania hospital discharge data from 1993 that demonstrated an inverse association between physician volume and in-hospital mortality after an AMI. That study demonstrated that patients of low-volume physicians who treated 1 to 6 AMI patients per year had a 43% higher in-hospital mortality rate than high-volume physicians, defined as those who treated 24 or more AMI patients per year... Physician volume was a stronger predictor of 30-day AMI mortality than was physician specialty in both our study and the Pennsylvania analysis...

"our results do suggest that significant reductions in AMI mortality could be achieved by shifting the primary responsibility for treating more AMI patients to a smaller number of high-volume physicians. Hospitals that have low-volume physicians could consider designating a few physicians to handle all of their AMI cases or they could mandate that low-volume physicians work with high-volume physicians when treating AMI patients."

The study counted deaths among 98,000 heart attack patients at Ontario hospitals from 1992-1998.

The graph below shows death rates decline steadily as the number of heart attack patients treated by a doctor rise from 1-2 to 34 or more per year:

"2011 ACCF/AHA Guideline for Coronary Artery Bypass Graft Surgery" American College of Cardiology Foundation/American Heart Association, pp. 35-36 

" 5.1.1... Class I - 1. All cardiac surgery programs should participate in a state, regional, or national clinical data registry and should receive periodic reports of their risk-adjusted outcomes..." Patients can ask for these "periodic reports" cited in the American Heart Association guideline 5.1.1

"Class IIb - 1. Affiliation with a high-volume tertiary center might be considered by cardiac surgery programs that perform fewer than 125 CABG procedures annually...

"In general, the best results are achieved most consistently by high-volume surgeons in high-volume hospitals and the worst results by low-volume surgeons in low-volume hospitals. (notes 793,794) However, many low-volume programs achieve excellent results, perhaps related to appropriate case selection; effective teamwork among surgeons, nurses, anesthesiologists, perfusionists, and physician assistants; and adoption of best practices derived from larger programs. (notes 833,834)

"As a quality assessment strategy, participation in a state, regional, or national clinical data registry that provides regular performance feedback reports is highly recommended for all cardiac programs. Random sampling variation is greater at low volumes... Ultimately, state or national regulatory authorities must decide whether the lower average performance of very small programs and the added difficulty in accurately measuring their performance are outweighed by other considerations, such as the need to maintain cardiac surgery capabilities in rural areas with limited access to referral centers."

They cite many studies on supplemental pages 33-39. Most address hospital volume, not surgeon volume.

KNEE REPLACEMENTS

"The role of surgeon volume on patient outcome in total knee arthroplasty: a systematic review of the literature" Rick L Lau, Anthony V Perruccio, Rajiv Gandhi, and Nizar N Mahomed. BMC Musculoskelet Disord. 2012; 13: 250. Cited by 3 articles.

"Mortality rate, survivorship and thromboembolic events [clots] were not found to be associated with surgeon volume [of knee replacements]. We found a significant association between low surgeon volume and higher rate of infection (0.26% - 2.8% higher), procedure time (165 min versus 135 min), longer length of stay (0.4 - 2.13 days longer [in hospital]), transfusion rate (13% versus 4%), and worse patient reported outcomes...

"After reviewing the available studies, we would identify a high surgeon volume as > 50 TKA [Total Knee Replacements] per year. Three studies identified a statistically significant relationship between low surgeon volume and higher infection rates (0.26% - 2.8% higher)...

"Early to midterm (up to 8 years) implant survivorship did not appear to be influenced by surgeon volume [notes 18,25,32]. Whether similar findings hold over the longer-term (i.e. >8 years) is unknown...
    "In the one study which examined patient-reported outcomes, Katz et al (2007) reported a positive association between LV [Low Volume] surgeons and poorer TKA outcomes [in US Medicare, study summary below]...

"Evidence suggests that some patients would refuse to have surgery in an unfamiliar setting, preferring to attend a local health provider with lower procedure volume [notes 35,52]. In the US, the poor, less educated, elderly, as well as racial/ethnic minorities are more likely to undergo TKA at low volume centers [notes 11,36,38]. Regionalization of TKA to high volume centres and surgeons may further exacerbate existing disparities in the utilization of TKA and restrict access to some patients who would otherwise use a low volume provider for TKA, increasing the number of patients who decline or defer their elective TKA surgery with resultant poorer health outcomes [notes 2,11,53]. A regionalization program involving referral to high volume surgeons and hospitals might decrease the already low rate of perioperative complications at the cost of increasing arthritis related disability [note 11]. Evidence suggests that having TKA in low volume hospitals costs more and produces worse outcomes than having TKA in high volume centers, but having TKA in low volume centers is still more cost effective than not having TKA at all [note 35]. While these studies were specific to examining the role of hospital volume on cost effectiveness of TKA, it is possible that the same may hold true for surgeon volume and TKA."


"Association of hospital and surgeon procedure volume with patient-centered outcomes of total knee replacement in a population-based cohort of patients age 65 years and older." Katz JN, Mahomed NN, Baron JA, Barrett JA, Fossel AH, Creel AH, Wright J, Wright EA, Losina E. Arthritis Rheum. 2007 Feb;56(2):568-74.  Cited by 30 articles.

"The questionnaires assessed lower extremity functional status using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) [notes 17,18]. The WOMAC contains... a 17-item scale that assesses lower extremity functional status... 

"Scores <60 indicated poor outcome. Sixty is a typical preoperative score... WOMAC functional status scores <60 increased from 10% among patients of surgeons who performed >50 cases per year in the Medicare population to 20% among surgeons who performed ≤12 per year...

"Patients operated upon in higher volume hospitals by higher volume surgeons had the lowest rates of worse functional outcomes (WOMAC functional status score <60, unable to flex the knee 90 degrees, unable to extend knee fully), while patients operated upon by lower volume surgeons in lower volume centers had the highest rates of these poor functional outcomes...

The risk of a poor WOMAC score ranged from 8.4% for patients in the high-volume centers operated upon by a high-volume surgeon to 22.6% for patients in low-volume centers operated upon by low-volume surgeons...  The finding of a volume effect on function and range of knee motion, but not on pain or satisfaction, suggests possible mechanisms. In high- and low-volume settings, the pain generator, the arthritic knee, is removed during surgery in all patients. Thus, pain relief is generally excellent. However, low-volume surgeons in low-volume centers may be less skilled at soft tissue balancing required to achieve the normal motion necessary for full function."

The study used questionnaires from a random sample of 906 Medicare patients 2 years after their total knee replacements, which were in 2000. These provided a 58% response rate among those sampled and invited.

HIP REPLACEMENTS

"Early failures of total hip replacement: effect of surgeon volume." Losina E, Barrett J, Mahomed NN, Baron JA, Katz JN. Arthritis Rheum. 2004 Apr;50(4):1338-43. Cited by 30 articles.

"Clinicians should consider surgeon volume among the factors influencing their referrals for elective THR." [Total Hip Replacement]

"Patients of low-volume surgeons have higher rates of revision THR than patients of high-volume surgeons, particularly within the first 18 months postoperatively."

15,000 elective Medicare hip replacements were done in 1995 by surgeons who did less than 12 Medicare hip replacements that year. 4.5% of these needed to be redone (revised) within 4 years, usually within 18 months. Among the 42,000 hip replacements done by surgeons who did 12 or more, 3.5% needed to be redone. This is a noticeable difference if you are in the 1% who avoided a second hip replacement. See graph below.

"Our definition of THR failure was simply the occurrence of a revision THR. Clearly, patients can have a poor outcome of THR yet not receive revision surgery, either because they prefer not to have surgery or because they are poor surgical candidates...

"Medicare population represent at least 67% of the total number of THRs performed in the US."

" 'Hello, I'm Dr. Gawande. I'm one of the surgical residents, and I'll be assisting your surgeon'... Yet to say I just assisted remains a kind of subterfuge. Otherwise, why did I hold the knife? Why did I stand on the operator's side of the table? Why was it raised to my six-feet-plus height?...

"When an attending physician brings a sick family member in for surgery... a first-timer is certainly not going to do it. Conversely, the ward services and clinics where residents have the most responsibility are populated by the poor, the uninsured, the drunk, and the demented...

"You do get good at certain things, my father [a urologist] tells me, but no sooner than you do, you find what you know is outmoded, New technologies and operations emerge to supplant the old, and the learning curve starts all over again. 'Three-quarters of what I do today I never learned in residency,' he says. On his own, fifty miles from his nearest colleague... he has learned to put in penile prostheses, to perform microsurgery, to reverse vasectomies, to do nerve-sparing prostatectomies, to implant artificial urinary sphincters. He's had to learn to use shock-wave lithotripters, electrohydraulic lithotripters, and laser lithotripters (all instruments for breaking up kidney stones); to deploy Double J ureteral stents and Silicone Figure four coil stents and Retro-Inject Multi-Length stents (don't ask); to maneuver fiber-optic ureteroscopes... 

When an important new device or procedure comes along, as they do every year, surgeons start out by taking a course about it -- typically a day or two of lectures by some surgical grandees with a few film clips and step-by-step handouts. We take a video home to watch... But there's not much by way of hands-on training. Unlike a resident, a visitor cannot scrub in on cases, and opportunities to practice on animals or cadavers are few and far between. (Britain, being Britain, actually bans surgeons from practicing on animals.) ... Patients do eventually benefit -- often enormously -- but the first few patients may not and may even be harmed... you can't train novices without compromising patient care... 

"Do we ever tell patients that because we are still new at something, their risks will inevitably be higher, and that they'd likely do better with others who are more experienced? Do we ever say that we need them to agree anyway? I've never seen it. Given the stakes, who in their right mind would agree to be practiced upon?... 

"I noticed on the expert's desk a picture of his child, born just a few months before... 'So did you let the resident deliver?'... 'No,' he admitted. 'We didn't even allow residents in the room.'...

"If you're going to do nothing but fix hernias or perform colonoscopies, do you really need the complete specialists' training (four years of medical school, five or more years of residency) in order to excel?"

Limited Quality of First Training

"Does resident post graduate year influence the outcomes of inguinal hernia repair?" Wilkiemeyer M, Pappas TN, Giobbie-Hurder A, Itani KM, Jonasson O, Neumayer LA. Ann Surg. 2005Jun;241(6):879-82; discussion 882-4. Cited by 7 articles

"Despite the presence of an attending surgeon, open hernia repairs performed by junior residents were associated with higher recurrence rates than those repaired by senior residents."

96% of hernia repair operations in the study had interns or surgical residents doing or helping with the operation. Interns and 2nd year residents had a recurrence rate on open hernia repairs (not laparoscopic) of 6.4%, 3rd year residents had 3.0%, and 4th or later year residents had 1.1%. 

All levels averaged 9.8-11.5% recurrence on laparoscopic hernia repairs. "Only when the attending surgeon and the resident are highly experienced in laparoscopic repair techniques, are recurrence rates for laparoscopic repairs reduced."

"Hands-on instruction and graded clinical responsibility are integral components of surgical education in North America... One variable that could have affected the results seen in this study is degree of attending surgeon supervision. Fallon et al (note 11) have reported that, when surgical procedures were performed with low levels of attending surgeon supervision, complication levels and mortality were raised... 

"Under these circumstances, the results we describe raise important questions about the effectiveness of supervision of inexperienced surgery residents. While it is understandable that the instruction of an inexperienced resident will take longer and lengthen the operative time, why were recurrences more common when junior residents were involved? Should not the supervising surgeon corrected [sic] any errors in technique and achieved the same outcome as if the attending surgeon had performed the operation?"

The attending surgeons knew they were part of a study where results would be measured. Would they do even worse normally?

"If experience is required of a closely supervised surgery resident to achieve optimal patient outcomes, how is it possible to begin the educational process for a surgeon-in-training and still safeguard each patient’s welfare?... Which points in each procedure are most vulnerable to inexperience? What must the attending surgeon do to confirm accomplishment of maneuvers critical to the outcome of the procedure?... None of these questions has been adequately addressed by surgical educators... 

"Hopefully, the future will include better training tools for teaching surgical procedures outside of the operating room... 

"Should only senior residents do hernias? I think the answer is clearly no. I think we have to be better at teaching interns and second-year residents how to do these operations."

One question in the discussion published with the paper asked, "do you plan to change anything based on patient informed consent, given the data in this study?" No further discussion of patient information or consent was given.

Weaknesses of Senior Doctors, Benefits of Simulators

"Expertise in Medicine and Surgery" Norman, Eva, Brooks, Hamstra, chapter in Cambridge Handbook of Expertise and Expert Performance, edited by Ericsson. Charness, Feltovich, Hoffman. Cambridge University Press, 2006. cited by 133 studies.

"Systematic consideration of the causes of poor performance in older physicians suggests that premature closure (i.e., excessive reliance on one’s early impressions of a case) may be the primary source of difficulty for those with more experience (Caulford et al., 1994). In other words, more-experienced physicians appear more likely to accurately diagnose using pattern recognition, but as a result of increased reliance on this strategy, they also run the risk of being less flexible, failing to give due consideration to competing diagnoses (Eva, 2002). Historical work into the cost of experience confirms that the more one relies on automatic processing, the harder it is to exert cognitive control when problem solving (Sternberg & Frensch, 1992). More recently, Hashem, Chi, and Friedman (2003) have presented data supporting this idea, showing that medical specialists have a tendency to pull cases towards the domains in which they have the most experience."

"Several studies (Anastakis et al., 1999; Matsumoto et al., 2002; Grober et al., 2004) have now shown that technical skills acquired on low-fidelity bench models transfer to improved performance on higher-fidelity models (such as human cadavers), as well as live patients in the operating room, both in laparoscopic surgery (Scott et al., 2000) and anaesthesia (Naik et al., 2001)." This finding suggests that volume can be obtained in training, without putting humans at risk.

Studies published since 2006 show the continuing need for bench training, such as a 2014 plan for $100 laparoscopic simulators for constant home practice, not just $2,000 simulators for occasional practice at a hospital: "the laparoscopic approach is quite different and different skills are needed. The first is the ability to perform actions in three dimensions when only two can be observed on the monitor. The second is that the difference of depth perception, spatial relationship and long surgical instruments requires perfect eye-hand coordination. Moreover, the arms of the tools act as levers with a fulcrum at the site of the skin incision, and hence the real action with the tool handles is a mirror of the movement of the tool tips seen on the monitor." 

Simulation can include live animals, cadavers, artificial materials and virtual reality with tactile feedback. Some authors are concerned there is not enough time to train since residents are limited to 80 working hours/week in the US and 48 in the UK.

A 2013 synthesis commented that with the rise in laparoscopic training, "the open operative experience of current surgical residents has decreased significantly. This deficit poses a potentially adverse impact on both surgical training and surgical care. Simulation technology, with the potential to foster the development of technical skills in a safe, nonclinical environment, could be used to remedy this problem...

"This is particularly true with regard to skills required to competently perform technically challenging open maneuvers under urgent, life-threatening circumstances. In an era marked by a decline in open operative experience, there is a need for simulation-based studies." 

Another 2013 overview says simulation should be required in surgical training and asks why it is not, "simulation is still not a mandatory component of all surgical training...

"The role of simulation is not to replace conventional training in the operating room but rather to augment it. By training in a simulation laboratory, a surgeon can acquire the necessary cognitive, technical, and nontechnical skills to shorten his or her learning curve in the operating room."

They even recommend simulated operating rooms to teach group work. Current training fails "to address such nontechnical skills as communication, teamwork, situational awareness, decision making, and leadership. This failure to address nontechnical skills is not acceptable, given the evidence that communication breakdown and failures in leadership and teamwork might be the root cause in up to 60% of major perioperative complications."

The Medical Director and Chief Academic Officer at Carolinas HealthCare System: "Bullard and Hall say the $1 million [simulation] program has paid off by helping doctors and nurses respond to sepsis in the simulation center, rather than relying on real-time cases to learn the procedure. 'It used to be that you saw one, did one, and then taught one. But those days are gone,' Bullard says. 'It's no longer safe to practice that way. Residents learn better in experiential learning environments.' "

Benefits of High Volume per Year, Weaknesses of Older and Senior Doctors

"Prestige of training programs and experience of bypass surgeons as factors in adjusted patient mortality rates." Hartz AJ, Kuhn EM, Pulido J, Med Care. 1999 Jan;37(1):93-103. Cited by 10 articles.

Findings on Annual Volume and Lower Deaths:

"As with previous studies, we found that the more operations a surgeon performed [per year], the lower the mortality rate. notes 8-11 This association may result because a greater number of surgeries may improve physician performance. It is also possible that the best surgeons may be referred the most cases."

The study covered deaths among 83,500 patients in 1990-92 in Pennsylvania (46,000), New York (38,000), Wisconsin (3,000). Each NY surgeon had treated 200+ patients in 3 years. Each Pennsylvania surgeon had treated 30+ patients per year. The Wisconsin patients were only from Medicare, and only from 1 year, mostly 1990, and included surgeons who treated any number of patients.

Findings on Years of Experience, Academic Rank and Higher Deaths:

"Mortality ratios... increased with years of experience, age and academic rank." See graph below left.

Patients' web browsing, purchases and social media comments often reveal their diseases. A good poster and study show how hundreds of data brokers buy this health information and spread it widely. Books include Our Bodies Our Data 2017,  Dragnet Nation 2015, What Stays in Vegas 2014.

Articles by the Wall Street Journal and Abine (which sells anti-tracking software) explain how trackers get information from your browser. The Wall Street Journal's reporters found their own paper's site was unintentionally sending email addresses, real names, gender, birth year and other data to three companies along with IP address, until the reporters discovered the leaks. If a sophisticated company, which knows the value of its data, unintentionally sent the data out free, the problem must be widespread. Once a data broker gets this link of real name with IP address, they can link that name to all their other data about that IP address. The FTC confirms that companies sell massive data for matching with IP address, while pretending that names and addresses are not used.

Data brokers comb such releases to see the names which use each IP address, and keep those names on file. Thus in homes with a fixed IP address, no browsing is anonymous. At businesses where many users share IP addresses, the brokers can't always identify people, but they can track the web use of the business overall, and thus its plans. Top executives or departments may have distinctive browsers (e.g. presence or absence of cookies, use of certain websites), so they would stand out from the company as a whole.

Conversations in public places are also subject to electronic eavesdropping, and to security cameras' facial recognition tracking, since laws generally allow no expectation of privacy in a public place.

Another article here compares tracking and privacy on sites where consumers review doctors. The table below summarizes tracking software on these and other medical sites. The trackers tell data companies what diseases and treatments each person is researching.
