Health Behavior vs. Doctor-Patient Communications


It seem like everyone these days is focused on changing some aspect of patient health behavior. You know, getting patients to get a mammogram or PSA test, exercise more, take medications as prescribed, or simply becoming more engaged in their health care. If only we could change unhealthy patient health behaviors….the world would be a better place.

I agree with the sentiment, but I think that patients and their health behavior often get a “bad rap” from health care professionals. I would even go so far as to say that much (not all) of what we attribute to poor patient behavior is more correctly attributable to ineffective doctor communications with patients.

In my last post I talked about the link between strong physician advocacy, e.g., I recommend, and desirable health outcomes, i.e., patients getting more preventive screening.

Here’s what I mean. Mammography studies have consistently shown that screening mammograms rates would be much high if more physicians “strongly recommended” that women get screened, e.g., “I recommend” you get a mammogram. In studies where physicians advocated for screening, mammography screening rates were always higher compared to physicians that did not advocate for them.

The same phenomenon can be found in studies dealing with exercise, weight loss, colorectal cancer screening, HVP immunization, and patient participation in clinical trials. In cases where physicians unequivocally recommended to patients that they do XYZ, patients were much more likely to do it…or at least they were much more likely to try. I am not naive enough to believe that an unequivocal recommendation from a physician is a “cure all” for the most recalcitrant patients. Factors such as level of patient trust in the physician and patient’s agreement with the physician’s diagnosis are mediating factors. Depression and fatigue from dealing with chronic conditions also play a role. But the evidence clearly suggests that a good many patients probably would respond positively to a strong recommendation from their physician.

Here’s an anecdotal experience describe by a physician comment on my last blog post:

“I agree that doctor-patient communication is critically important. My 50 year-old best friend shuns doctors, but told me he is getting a colonoscopy because his doctor strongly recommended it. “

Here’s the basis for my thinking. Many patients operate on the principle that if my doctor thinks something is important they will tell me. On this point patients can be quite literal. I have seen studies in which obese patients do not see themselves as “obese.” Their self perception is validated every time their doctor fails to tell the patient that they have a serious weight problem and that they need to lose 20 pounds in no uncertain terms. If I have such a big weight problems why hasn’t my doctor said anything?

Think back to your recent trips to the doctor. If you are like me, you may be hard pressed to think of a single instance in which your physicians ever said the words “I recommend” to you.

The only such instance I can recall was when my wife’s oncologist (Stage 4 Lung Cancer) said “I recommend that you start the chemo treatment immediately….tomorrow wouldn’t be too soon.” My wife did what her doctor recommended and she is alive today some 6 years later.
