摘要:As in other sectors, increasingly higher performance and efficiency are also being required from health care employees. To achieve this goal, every health care organization should have a suitable human resource management system. The selection, education, training, effective performance appraisal, and evaluation of leaders are particularly of key importance for every organization. Data envelopment analysis (DEA) is used in this study to develop a model of practice outputs and inputs to help identify the most efficient nurse leaders. The employees’ performance appraisals are often closely related to their specific organizations. As leaders’ behaviors are also influenced by external, non-discretionary factors, the three-stage DEA was used to include inputs not controlled by individual leaders. This article proposes a performance appraisal based on competency models of leadership for a larger professional group working across several different organizations, yet in similar professional and institutional environments. The empirical data in this article are based on two surveys that were conducted in 15 Slovenian public hospitals.
