Measuring anaesthetic outcomes.

We have identified some of the most frequently measured anaesthetic outcomes and their independent risk factors, and discussed the limitations and advantages in using various risk adjustment strategies. Many studies suggest that preoperative assessments may contribute to preventing the occurrence of anaesthetic-related morbidity and mortality, and to high levels of patient satisfaction. The use of health status measurements as a preoperative screening tool in assessing anaesthetic risk offers a potential area for future work. Research into measuring anaesthetic outcomes in a reliable and valid manner will be an important tool in improving standards of anaesthetic practice and in delivering quality anaesthesia to our patients.
