BACKGROUND: Intra-operative @entity591 is a common adverse event, often recorded as an indicator for process quality in quality assurance projects in anaesthesia. METHODS: This retrospective study is based on data sets of 28,065 @entity1 recorded with a computerised anaesthesia record-keeping system from 23 February 1999 to 31 December 2000 at a tertiary care university hospital. Cases were defined as @entity1 with intra-operative @entity591 ; references were automatically selected according to matching variables (high-risk surgery, severe @entity712 , severe @entity453 , significant @entity543 and/or history of @entity64 , @entity177 , @entity6 and urgency of surgery) in a stepwise fashion. Main outcome measures were hospital mortality, admission to the intensive care unit (ICU) and prolonged hospital stay. Differences in outcome measures between the matched pairs were assessed by univariate analysis. Stepwise regression models were developed to predict the impact of intra-operative @entity591 on the different outcome measures. RESULTS: In our study 474 @entity1 (1.7%) were found to have had intra-operative @entity591 . Matching was successful for 99.4% of the cases, leading to 471 cases and references. The crude mortality rates for the cases and matched references were 5.5% and 2.5%, respectively (P=0.020). Of all case @entity1 , 22.3% were treated in an ICU, compared to 11.0% of the matched references (P=0.001). Hospital stay was prolonged in 25.1% of the @entity1 with @entity591 compared to 15.1% of the matched references (P=0.001). CONCLUSIONS: In this study, @entity1 with intra-operative @entity591 who were undergoing non-cardiac surgery had a greater peri-operative risk, leading to increased mortality, greater frequency of admission to an ICU and prolonged hospital stay.
