Patients need more accurate information on their prognosis

Why are doctors so bad at predicting how long a patient has to live?

That’s the interesting question posed by John Schumann, an internal medicine physician who blogs at GlassHospital, recently in Slate.

There are many reasons why doctors evade the question of prognosis:

We don’t like to be wrong; we don’t want to take away hope for survival or good quality of life in the time that remains; and we just aren’t adequately trained to do it. And our reluctance to make such guesses means that when we do try to predict the future, we’re pretty lousy at it.

The last issue — poor training — resonates.  Research shows that, in “teaching, and communication, we focus almost exclusively on the ever-expanding sciences of diagnosis and treatment, leaving prognosis almost entirely to the side.”

Most textbooks focus almost exclusively on diagnosis and treatment, limiting prognosis to “a paragraph or less.”

I like Dr. Schumann’s suggestion that doctors be more analytical when giving prognostic information to patients and families in terminal cases:

Prognosis should not be left to the realm of mordant comments in pathology lectures or sotto voce remarks to students and residents outside a patient’s room during ward rounds. Instead, medical education at all levels should feature actuarial information on the major causes of death, with modification for the age of the patient and the various treatment options.

So when confronted with the question, “How long do I have to live?”, it’s essential that better education encompassing a more actuarial approach will train doctors to give the answers patients need.

But like much of medicine, that push needs to come from patients in order to overcome the inertia that resists any change in the way physicians normally do things.  Don’t be afraid to ask your doctor for specifics when it comes to your prognosis.
