[Man at risk. Preventive strategies and risk management for patient safety]

Abstract

Anaesthesia-related risk has been significantly reduced within the last decade. Nevertheless the risk and the possibility of dying or suffering permanent damage still exist. To improve patient safety, risk assessment and analysis must lead to the development of preventive strategies. For this purpose anaesthesia can rely on the concepts of other "high reliability" organisations such as aviation or nuclear power plants. Analyses of critical incidents in the different fields confirm that next to technical problems human factors account for most of the preventable mishaps. Human factors are responsible for individual mistakes as well as for organisational errors. Therefore besides traditional concepts of risk reduction (e.g. guidelines) new strategies (e.g. full-scale simulation) must be applied to minimise the negative impact of human factors on patient safety. Risk management has to consider technical, organisational and human factors to implement a higher standard of patient safety.
