Run by a group of GPs, Red Whale | GP Update teaches large numbers of GPs, GP specialist trainees and primary care nurses every year: we scour the published literature and summarise all the research and guidance relevant to primary care, so that the best available information is easily accessible to those at the primary care coal face. We think it is crucial that all trials are registered and published, whatever the result, so that healthcare professionals together with their patients can make the best choices for care for each individual.
