In line with this aim, the effect of service quality perceptions and corporate image on patient satisfaction was analysed through the data acquired from 307 patients at Dumlupinar University Kutahya Evliya Celebi Education & Research Hospital using multiple regression model. Moreover, the patients’ perceptions about service quality dimensions were also evaluated through the same data. As a result of the analyses, it was determined that the highest perceptions of the patients about service quality dimensions turned out to be in tangibles and reliability dimensions.
