Technical efficiency of Portuguese public hospitals: A comparative analysis across the five regions of Portugal.

The present study aims to analyse the efficiency scores of hospital units, with reference to the five Portuguese health administrative regions (North, Centre, Lisbon and Tagus Valley, Alentejo, and Algarve). This paper contextualizes the process of decentralization of health in Portugal (started 1993) as well as the hospitals' corporatization and merging reforms (started 2002). These reforms aimed to meet health care needs by optimizing costs, improving efficiency, and broadening both access and quality in health services. Data envelopment analysis was used to quantify and compare the efficiencies of 27 hospitals heterogeneously distributed by five administrative regions. The results show a large average performance across the country. However, there are regions with scores larger than the national average and others with inferior results. This interregional diversity points towards disparities that deserve special attention from the policymakers and hospital managers.
