In terms of healthcare, making a correct diagnosis is fundamental to subsequent decisions about treatment. Making a correct diagnosis is one of the main reasons why training to be a doctor takes such a long time.Yet, have you ever thought why there is so little published on this topic? When did you last see one of the major clinical journals discuss its importance?
Because it is definitely important, it affects referrals, errors, reasons for admissions, over testing, and in some cases leads to over diagnosis.
If you are interested in diagnostic reasoning, I recently interviewed John Balla, who published on the diagnostic process as far back as 1985. This is designed as an introduction to this area, alongside some of the important publications: all in 40 minutes.
