When doctors receive an HDC complaint about our clinical care, and expert opinion is always obtained. How does the GP expert measure our care? What are the most common errors GPs make? We are privileged to interview Dr David Maplesden, HDC in-house GP expert, in this series of 3 podcasts. Over the series David explains how he approaches the cases, his role and the common pitfalls that GPs make in the cases he sees including the interface between primary and secondary care, our responsibility to chase referrals, missed cancers, capacity assessment and much more.
