Ideas on improving rates of missed/delayed diagnoses in PCP type visits.

Yes, technology and patient input and collaboration. 

What about asking for a patients' diagnosis where possible. That would encourage collaboration and prior research.

IHI successfully did this for hospital based quality. The problem is that diagnostic encounters are hard to track, and the speed and accuracy of diagnosis are hard to measure. We need more than recognition and classification of errors. Without the denominator, we can't measure reliability.

Our problem is that good decision making habits are not uniformly and consistently applied. We need more research on the implementation phase of medical decision making. What are the best ways to teach a reliable, consistent, and systematic approach to medical diagnosis?

There are a lot of good ideas expressed, but it seems like we all have an oar in the water and we are all pulling in different directions. Seems like we could make more progress if we pulled in the same direction by acknowledging some common goals.

We need to focus on physicians. Computers are very reliable, so how can they be used in decision support to improve physician decision making? Some patients are very engaged in their quest for a diagnosis. How can we channel that motivation to help physician decision making? How can we teach physicians to appropriately engage their patients in a fruitful collaboration that results in better diagnosis? Waiting for computers to take over medical diagnosis is a false hope. Training every potential patient in diagnostic technique would be impractical and impossible. We need to focus on physicians, who society continues to entrust to make the vast majority of diagnoses. Medical trainees get less and less training in medical cognition, and we need to turn this around.

Sure, some physicians deserve blame for sloppy thinking, but blaming physicians as a group for failed diagnosis is exactly the wrong thing to do. Our best hope for improvement is engaging physicians and improving their reliability through better education of good cognitive habits, through better support from technology, and through better collaboration with their patients.

Misdiagnosis, on most fronts, appears to originate in the domain of human experience. There is a lot of great science and techonology that supports the ability to make accurate diagnoses, but as we've noted in so many different words, at the end of the day, the practice of medicine is a human endeavor. When researchers must reach for anecdotal reports to support theories or arguments, it is an indicator that there is a significant gap in the research. There has been a great deal of discussion on another thread about logic and decision making processes. All well and good, and important, I think, to improving diagnosis. However, in reading these postings and reviewing the literature, it has become apparent to me that there is a need for qualitative research regarding misdiagnosis-- both from the patient and physician perspectives. I believe that thoughtful collection of anecdotal reports, combined with meta analysis of the existing literature, will guide the way to significant advances in improved diagnostic accuracy.

I had a doctor who had seen cachexia and the like, also figured out the first time from "normal" blood work (normal for ranges but not for me) that I had a nutritional anemia. The "normal" blood work had items showing high normal/low normal values in the appropriate places. Allowing a computer or a person to simply read those and not be able to interpret symptoms and then the blood work in light of that, was what caused months of delay in getting treated.

>>> > Psychiatric misdiagnosis is common. An American doctor, Robert S. Hoffman, blames the process on a chain of irreversible and tragic events, whereby 'a primary physician applies a preliminary diagnosis of mental disorder which is decisive in determining the patients' subsequent course. Once the stigma of psychiatric disorder is appplied to an individual it can be impossible to remove it. Of 215 psychiatric patients in America, tests revealed that 41 percent should probably have not been referred in the first place, 63 percent had wholly treatable conditions. At a Manhattan psychiatric center, 131 patients selected at random were examined, and it was concluded that up to 75 per cent of them had been misdiagnosed when first admitted to the hospital. A principal error is to mistake signs of physical illness as emergent psychiatric problems. Instead of looking to practical remedies, which may be connected to lifestyle, emotional problems or some biochemical imbalance, the doctor prefers to lump what he does not understand under the heading of mental illness and thrust a patient into an institution, or put him on mind-altering drugs which may have irreversible effects.
