“…The review of literature has revealed that most of the DEA method-based relevant efficiency analyses on hospitals are based on non-financial input and output variables. While the number of health-care employees (such as doctors, assistants, nurses, auxiliary health-care workers) and the total number of beds are used as input variables, the number of outpatients, inpatients, and discharged patients, hospital bed occupancy rate, hospital bed turnover rate, the total number of hospitalization days, the total number of surgical operations, and hospital death rates are used as output variables (Atmaca et al, 2012;Bayraktutan & Pehlivanoğlu, 2012;Franco Miguel et al, 2018;Gülsevin & Türkan, 2012;Kutlar & Salamov, 2016;Li & Dong, 2015;Yiğit, 2016) There are also studies in the literature, although not many, which defined inputs and outputs based on both financial and non-financial data or based only on financial data to measure performances of health care enterprises through DEA method. In such studies, total expenses variable is used as an input variable in addition to variables of specialist physicians, practitioners and the total number of hospital beds, whereas total income is used as an output variable in addition to the variables of outpatients, major surgeries, and the number of hospitalization days (Bal, 2013;Czypionka, Kraus, Mayer, & Rohrling, 2014;Temur, 2010;Temür & Bakırcı, 2008).…”
