The Effects of Information Systems on the Performance of Medical Units: the Case of Operating Rooms

The paper applies various qualitative and quantitative methods to measure the influence of information technology on the performance of operating rooms (ORs). It provides a comprehensive set of indicators to evaluate the impact of IT on the quality, efficiency and performance of ORs. This set of indicators was further enriched by conducting interviews with hospital professionals. The result is a new set of performance indicators, divided into five major categories: productivity, efficiency, quality, cost savings and employee satisfaction. This set of indicators serves as of a basis for a weighed performance model that can be applied as a useful tool for selecting new OR information systems or for improving existing applications. The research identifies time registration, integration with the medical and financial systems of the hospital and production of activity queries and reports as the most common functions of ORs systems. However, despite their potential to contribute to productivity, efficiency and quality of ORs, automatic conflict recognition, material and personnel planning are less frequently applied by hospitals. Finally, the paper highlights the links between efficient use of OR systems, larger volume of operations and helps and higher occupation rates, identifying positive effects of systems used in ORs on their performance.
