Eventos adversos em hospitais britânicos: revisão preliminar retrospectiva de prontuários
Objectives: To examine the feasibility of detecting adverse events through record review in British hospitals and to make preliminary estimates of the incidence and costs of adverse events.
Design: Retrospective review of 1014 medical and nursing records.
Setting: Two acute hospitals in Greater London area.
Main outcome measure: Number of adverse events.
Results: 110 (10.8%) patients experienced an adverse event, with an overall rate of adverse events of 11.7% when multiple adverse events were included. About half of these events were judged preventable with ordinary standards of care. A third of adverse events led to moderate or greater disability or death.
Conclusions: These results suggest that adverse events are a serious source of harm to patients and a large drain on NHS resources. Some are major events; others are frequent, minor events that go unnoticed in routine clinical care but together have massive economic consequences
