Why the study?
Are intra-operative incidents associated with increased hospital mortality and resource utilisation in patients undergoing anaesthesia?
Are intra-operative incidents associated with increased hospital mortality and resource utilisation in patients undergoing anaesthesia?
Intra-operative incidents are independently associated with increased postoperative resource utilization, specifically longer stays in the postanaesthesia care unit and hospital, though they do not independently increase mortality.
Incidents were associated with longer PACU and hospital stays; leaves open causal effects on mortality and need for targeted prevention.
We assessed the predictive value of intra-operative quality indicators (incidents) with respect to outcome (hospital mortality) and resource utilisation (length of stay in the postanaesthesia care unit and in hospital). Institutional data obtained from reports of a quality system that complies with the ISO 9002 standard were evaluated retrospectively. Incidents occurred in 2009 of 25 091 anaesthetics. Mortality was higher after incidents than after uneventful anaesthetics, but in multivariate analysis the incidents did not contribute to mortality. Length of stay in the postanaesthesia care unit and hospital were longer after incidents (p < 0.001 for both). In multivariate analysis, incidents independently contributed to length of stay in the postanaesthesia care unit among ASA I-III patients (p < 0.05, 0.001 and 0.001, respectively) and to length of hospital stay among ASA II-III patients undergoing scheduled operations (p < 0.05 and < 0.01, respectively). Intra-operative incidents are associated with increased resource utilisation following surgery.
