In a previous blog we demonstrated how guidelines can compromise the care of individual patients when designed to serve the health care system.
Why should treating physicians defer to guideline committees at all, we asked? For decades medical students have been taught to read and understand information from published papers.
We are all trained in critical appraisal and can keep up with the clinically meaningful literature, the literature that is relevant and accurate enough to present to patients. Just because there are nearly 20,000 biomedical journals does not mean that any, let alone all are replete with meaningful information. We can discern the valuable from the not valuable; why do we need others to tell us?
In fact, we even argued in our last post that patients can and should judge the value of medical information. After all, they face the consequences of misinterpreting the likelihoods of benefit and of harm associated with various options for care.
No one remembers the numbers that describe the chances for benefit and harm or ask more questions about the veracity of information than a patient who must choose. The smartest information managers we have ever encountered are our patients; when informed, they quickly determine the validity of the information and apply their personal values to the estimations of the chances for benefit and harm.
Take the example of a patient who recently entered into a therapeutic dialogue with one of us, RAM. This was not the traditional clinical interview. This patient had been diagnosed with prostate cancer and was scheduled for an approach to treatment that the diagnosing physician had offered as the most sensible. However, the decision did not rest easily.
The appointment with RAM was scheduled because the patient sought a dialogue that might offer a chance to reflect on the rationale for the approach he was about to initiate. Two hours into the dialogue, the patient, a 40ish year old African-American man accompanied by his wife, were mulling over the marginal benefits and harms of the options for treating an early stage prostate cancer.
The wife asked how many African-Americans were in the study under discussion. “None”. The husband perked up and then asked, “How many people in the study was my age?” “None”. They then asked if the difference in benefit was a certain, fixed amount? “No, it varies over this range.” – examining the descriptive statistics.
They then asked when the study was started and did it pertain to the present day. “It started over 15 years ago” and the stage of disease of the men in the study was generally more aggressive than in this particular case.
