Assessment of operating theatre procedures and quality of perioperative anaesthesia using a computer system for collecting anaesthesiological data

Background. In order to manage the operating theatre and guarantee constant improvement in the quality of procedures, it is indispensable to be able to have available a computerised workstation to enable the team to collect data and analyse them. Methods. We used our anaesthesia department's computer workstation to retrospectively analyse operating sessions over a 16 month period during which organisational adjustments were made to optimise patient turnover and maximise the utilisation of operating theatres. Meantime we studied and compared the trend in anaesthesiological quality through the use of certain structural, process and outcome indicators. Results. During the period under study an improvement was noted in the efficiency of operating theatre procedures (reduction in entry time of the first patient into the theatre, time between one case and the next and subutilisation of the operating theatre, p<0.05). As regards data on the quality of anaesthesiological assistance to the patient, no significant differences were noted when comparing the four periods examined. Conclusions. To make the operating complex work more efficiently, it is necessary to have available a computer system that makes it possible to continuously monitor theatre operation. The improvement initiatives undertaken led to a more effective utilisation of the operating theatre but did not produce a significant increase in productivity. In spite of the increased work load, analysis of the trend in quality indicators as regards anaesthesiological procedures did not reveal any modification.
