BATTING AVERAGES 
While I'm not a hard-core baseball fan, nonetheless I do enjoy following the
exploits of not only our hometown Pittsburgh Pirates but also other baseball
teams with which I am connected, at least indirectly by virtue of time I spent
during my education and training in cities in which those baseball teams are
located. I never cease to be amazed by a baseball announcer's ability to rattle
off volumes of information, such as pitching and batting statistics, about any
baseball player. For instance, the performance of a certain right-handed batter
against a certain left-handed pitcher with a certain number of men on base in
a certain ball park.
There is no doubt in my mind that the average patient (certainly just about
all of my patients) would like similar information about their physicians, particularly
surgeons who by definition become more "intimately" involved with
their patients than do non-surgeons. I'm sure many of my patients would like
to know what my batting average is. How do I perform with regard to a certain
surgical procedure undertaken on a patient of a certain age, height, weight,
etc. on a certain day of the week at a certain time of the day? I think you
get the picture. While of late hospitals and health insurers, in response to
pressure from consumer groups and government agencies, have undertaken statistical
analyses of the performances of surgeons, particularly cardiac and other surgeons
who deal with life and death situations on a routine basis, these statistical
analyses, without appropriate supportive information, usually are flawed from
the outset and consequently meaningless at best and potentially dangerous at
worst. Let me explain.
Some years ago while I was in training in general surgery at Georgetown University
Hospital (GUH) in Washington D.C., I worked with a remarkable surgeon who dedicated
himself to the treatment of particularly difficult surgical problems other surgeons
refused to touch. At GUH he became the "court of last resort". Not
surprisingly his mortality rate (in other words the number of patients who died
while under his care) probably varied at anytime from 10% to 15%, which even
a non-physician would agree is a remarkably high percentage of deaths. Judged
by his mortality rate alone, most people, even knowledgeable physicians, would
assume him to be a terrible surgeon and one who should be prevented from practicing
medicine. Yet those of us who worked with him and knew him well recognized that,
given the nature of the patients and surgical problems who/which he treated,
his mortality rate of 10% to 15% was unusually low. In the hands of a "lesser" surgeon,
that same mortality rate might be 50%. Consequently, he was curing anywhere
from 3 of 10 to 4 of 10 more patients than would/could other surgeons faced
with the same "mix" of patients and surgical problems. Needless to
say, to those of us in the know, he became the surgeon of choice, even for minor
surgical problems.
In like manner the success rate, complication rate, medical malpractice suit
rate and so on of any surgeon often are a function of factors not related to
his/her competence or abilities. Complications such as post-operative bleeding,
infection, tissue death and loss, etc. can arise even under the best of circumstances
and despite the best efforts of all "parties" to a surgical procedure.
My complication (and "re-do surgery") rate for Rhinoplasty (nose reshaping)
is virtually 0%, compared to a nationwide rate of 1% to 2%. My complication
(and "re-do surgery") rate for Bilateral Breast Augmentation is in
the neighborhood of 1%, compared to a nationwide rate of 4% to 5% and even more.
In other words, essentially none of my Rhinoplasty patients require additional
unanticipated post-Rhinoplasty surgical care whereas about 1 in 100 of my Bilateral
Breast Augmentation patients do require additional unanticipated post-Bilateral
Breast Augmentation surgical care. At which of the foregoing two surgical procedures
am I more competent? Rhinoplasty, because of my 0% complication/"re-do
surgery" rate? Or Bilateral Breast Augmentation, because my complication/"re-do
surgery" rate for that surgical procedure "beats" the corresponding
national rate by a wider margin than does my complication/"re-do surgery" rate
for Rhinoplasty? Many of my patients would like to think that the competence
or lack of competence of a surgeon can be determined by the number of medical
malpractice suits filed against him/her. In fact, medical malpractice suits
these days are more a reflection of the litigious society in which we live,
the vulnerability of physicians to such suits and certainly, in my specialty
at least, the difference between the expectations, sometimes unrealistic, of
a patient undergoing surgery and the ability of the surgeon/surgery to meet
those expectations.
My point, I'm sure you've guessed, is simply that statistics, particularly
with regard to performance by physicians in general and surgeons in particular,
are meaningless when those statistics are evaluated in a vacuum. They are meaningful
only when many variables, some of them even confusing to other physicians, are
factored into the analysis which produces those statistics. Perhaps one day
as surgeons enter operating rooms across the country to ply their crafts, disembodied
voices will introduce them over loudspeakers in those operating rooms and provide
those assembled in those operating rooms with information about each surgeon's
performance in terms of complication rate, mortality rate, medical malpractice
suit rate, etc. By that time I hope I will be enjoying retirement, since I for
one wouldn't want to practice medicine in such an analytical environment which
does not recognize the inherent "humanness" of the medical profession.
