I don't see how. You say I had six surgeries last year and of that
1 had this problem, 2 this one, etc. You aren't releasing any
identifiable information in the context of the laws.
You also say that everyone practicing in the hospital (or county or
whatever the appropriate distinction is) did a total of X surgeries last
year and of that Y had this problem, Z had this one, etc.

If the information could be released in a way that didn't tamper with
patient confidentiality, that would be fine.

No. There is no such survey. Now, might we be able to create one that
would help? Possibly. But now you'd be relying on the patient reading that
Dr. Smith has more complications but a higher "severity survey" or "degree
of difficulty" and somehow making heads or tails over that. Since that's
hard enough to do for those that are actually doing the surgeries, it is
probably a bit much to ask of John Doe who fixes cars and needs his prostate
operated on.

Ok, I get it. If we find out a doctor harms patients, then that must
be
hidden to protect privacy. You just got done saying EVERYONE knew. Now
you
say it is unethical to let patients know about bad doctors. Figures.

Context, George, context. What information should be given?

Say prostate cancer surgery (I'm more familiar with this). Information
that
is potentially helpful to patients would include but not be limited to:
positive margin rate, postop urinary continence, transfusion rate, blood
loss, rate of bladder neck contractures, postop erectile function,
survival,
postop lymphoceles, rate of biochemical recurrence, length of hospital
stay,
etc etc.

These are all things I discuss with my patients. I don't hide any of
them.
BUT... should we all have this data readily available? If you're looking
a
surgery you do 6 times a year, and you live in a small town...
confidentiality becomes a real issue. If you are a tertiary care center
and

You'll see them cherry pick their surgeries. Why operate on a big fat guy
that has potentially for more complications? Why operate on an aggressive
cancer since you run a risk of lowering your average of having + margins?
Send him off to the nearest "University Hospital" for that surgery (with
all
the associated time delays risking metastatic cancer).

I dont' disagree with your basic premise that the patient should have a
way
to judge his doctor. I DO disagree with the blanket manner in which you
would want to implement that. You don't seem to have thought through the
repurcussions of that line of thinking, much like the politicians in
Washington.



Multivariate analysis could take care of all your objections, which are

Of course not? Fixing errors is part of the cost of doing business in
all other fields. If the mechanic ruins your car, the dealer's insurance
from the dealer covers that.

There are cases where a mechanic does the damage, but
claims it was due to a previous defect. In this case,
it is unlikely that you could collect from anyone.

If a doctor ruptures a colon, he states
Quote:
he/she
is not responsible but you are. Medicine is still based on the
small-business model of 1900, but there used to be personal responsibility
what went with that model.

In the small business model of 1900, the mechanic would
still be liable.

Quote:
If gastroenterologists had to pay out of pocket for the expenses of every
ruptured colon (let's say 1 in 100 or so, but I'm honestly not up to date on
the current perf rate) then they and all other MD's would cease to do
colonoscopies except in medical emergencies.

If I had to pay for all incontinence surgery after a prostatectomy (about
2-5% will have urinary leakage after surgery and require some sort of
procedure to correct that) I would stop doing them tomorrow and never even
consider doing one again.

In medicine there are known adverse events of surgery/procedures. We do our
best to minimize them. I agree we can and should do more. But the
cowboy/ignorant attitude of "well, just have the doctor pay the subsequent
medical costs" is not a solution - it's a childish knee jerk reaction that
has no basis in reality.

The patient needs to be informed of these dangers, and
quantitatively, before the medical action, except in
emergencies. You are right that this is the "cost" of
anything in any period of rapid change.

In fact, the FDA should not have the power to approve
or disapprove of a drug, provided that ALL of the known
information is provided, unless there is a public health
issue involved. YOU must evaluate the risks and benefits
from YOUR position and YOUR knowledge, taking into account
what the medical profession, etc., can provide. You might
be unlucky and a small amount of radiation can set off
a serious cancer, while someone else receiving hundreds
of times at much suffers no damage; do you have the right
to sue the makers of the radiation machine?

Everyone except the patient, who is never allowed to know who the bad
players are.

A patient in for a routine colonoscopy meets the doctor beforehand,
discusses the procedure, etc. If there is ever a perforation or some
other
problem, they know exactly who to come looking for.

But the patient never knows who is the player with a high number of
ruptures. That is carefully hidden from the patient. You wrote "EVERYONE
(hospital administration, coworkers, and the surgeon who comes out in the
middle of the night)" knows...but never the patient. Greshams law applies
here.



Quote:
And does anyone really keep track of the physician who
perforates colons at the higher rate than expected?

I'll be perfectly honest - yes and no. Since there is not one "correct"
perforation rate and since such events are rare, it would hard to measure
accurately.

You are engaging in mystification here. No one can know? You just got
done saying EVERYONE knows....know you say no one knows.


Quote:
That's the "no" part. The "yes" part is if there is an obvious
trend ... example 3 of the last 10 ended up colostomies - that would
noticed
by the department head, hospital administrator, and the general surgery
department.

Is that data every
systematically collected? Who would ever know? It is kept secret to
protect the system.

Who do you think should have access to such information?

PATIENTS

So patients should be given information about other patients? Hmm... that
might violate a few laws and ethical codes.


There is no suggestion that a patient know about any other
specific people. The question of providing useful information
without violating such laws and codes is well studied, and
while there is no perfect solution, giving patients information
about the number of such events in the past few years and
the number of bad results is within what could be done.

However, if some physicians see a different type of patient
than another, that information will be needed. If the
patients seen have many polyps removed, I would expect a
higher perforation rate than one for whom nothing is found.
But the patient definitely needs the relevant information.
I am just pointing out the difficulties in making things
too simple; as we must use statistics, we cannot be certain.

Data collection and reduction, accounting for known influences.
Nothing radical. I can think of any number of candidates for
the role, all of which would be in a position to remove personally
identifiable details and adjust for factors that affect outcomes
such as those you mention. One, just as an example, would be
the State medical boards. Already funded (if not enough to
really do their jobs), already (theoretically) with the charter
to perform "quality assurance" on medical care.

Once set up, it's much less complicated than what's already
going on with claims submittal, since the input data is the
same. The software itself is going to be common across the
USA and probably the world.

I suggest you study some of the problems of statistical
decision theory. The basic idea is simple; one should
consider

All consequences of the proposed
action in all states of nature.

The number of factors affecting results in medicine
is at least in the dozens, and we have no methods
yet for analyzing the non-linear problems occurring.
There are makeshifts, and probably nothing better
will be done until we have biochemistry advanced to
the status of basic physics, where we are measuring
physical constants to high accuracy. But these
relatively simple physical models are not too good
at weather forecasting, which is simpler than the
problems of biochemistry and medicine.

We do not have the relevant science, and the sample
sizes are nowhere near large enough for the complications
we already know about.

Alas, it is John Doe who must be the one to make the
decision. It is up to his physician to educate him
on the probabilistic aspects, which means that the
physician has to understand them. We should protect
people from their ignorance by enlightening them;
attempting to protect them by dictating should place
those who do the dictating subject to lawsuits.

In other words, if John Doe makes a decision which
turns out to be bad, he can only sue if his information
was wrong, or if there was clear malfeasance. But if
someone makes the decision for him, that person should
be fully liable.
