Dysfunctional doctors--will revalidation help?

Numbers of National Clinical Assessment Service referrals concerning practitioners' performance are much higher for the over-50s, especially in GPs. 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.

Insulin, hospitals and harm: a review of patient safety incidents reported to the National Patient Safety Agency.

Patient safety incidents involving insulin are frequent and cause considerable distress to people with diabetes and anxieties to their families and carers. This article describes an analysis of the National Reporting and Learning System database of patient safety incidents concerning insulin reported from NHS providers in England and Wales over six years. The main causes are discussed and the ongoing developments by the National Patient Safety Agency and partner organisations to reduce insulin errors are described.

Metformin therapy and clinical uses.

Metformin is now established as a first-line antidiabetic therapy for the management of type 2 diabetes. Its early use in treatment algorithms is supported by lack of weight gain, low risk of hypoglycaemia and its mode of action to counter insulin resistance. The drug's anti-atherosclerotic and cardioprotective effects have recently been confirmed in prospective and retrospective studies, and appear to reflect a collection of glucose-independent effects on the vascular endothelium, suppressant effects on glycation, oxidative stress and formation of adhesion molecules, stimulation of fibrinolysis and favourable effects on the lipid profile.

Metformin, heart failure, and lactic acidosis: is metformin absolutely contraindicated?

Many patients with type 2 diabetes are denied treatment with metformin because of “contraindications” such as cardiac failure, which may not be absolute contraindications
