In this 3 part series, we listen in on a webinar with Marelene Pearce, a GP based on the Sunshine Coast, QLD. We discuss "Diagnostic uncertainty in General Practice", looking at reasons why there is so much uncertainty in general practice, and how to cope with the uncertainty. In this episode, Part 1, Marelene talks about using clinical reasoning to assist with the dilemma, what to do when we're stuck and what pitfalls to avoid. She discusses the model we use in general practice, which is so different to what we were taught as medical students.
