“…Numbers of hospitals, beds, physicians, nurses þ midwives and other health personnel used as inputs in this study were also used as inputs in the studies conducted by Afonso and Aubyn (2011), Mutter et al (2008), Bilsel and Davutyan (2014), Lobo et al (2014), Karagiannis (2015), Samut and Cafri (2016), Chowdury and Zelenyuk (2016), Nistor et al (2017), Guo et al (2017), Du (2018), Guerrini et al (2018), Bobo et al (2018) and Habib and Shahwan (2020). Similarly, it has been observed that the variables of number of outpatients, proportion of inpatients and surgeries and risk-adjusted crude mortality rate are used in most studies in the literature (Mutter et al, 2008;Bilsel and Davutyan, 2014;Lobo et al, 2014;Chowdury and Zelenyuk, 2016;Nistor et al, 2017;Guo et al, 2017;Du, 2018;Bobo et al, 2018;Habib and Shahwan, 2020). The control variables used in this study (proportion of university graduates, GDP per capita, metropolitan status and population) were found to have an effect on the efficiency score in the studies conducted by Afonso and Aubyn (2011), Bilsel and Davutyan (2014), Karagiannis (2015), Samut and Cafri (2016), Guo et al (2017), Du (2018) and Bobo et al (2018).…”
