In 20% of cases there are concerns with diagnosis that are unlikely to be recognised by revalidation. Accurate and timely diagnosis is fundamental to patient safety, and the results of studies in which GPs were tested using mystery patients are not encouraging. We need to assess pratictioners' competencies in diagnosis throughout their careers. Plans to extend working life may require changes to the clinical responsibilities of older doctors.
