Abstract The main purpose of our study is to determine the multidimensional risk factors in healthcare organisations based on the literature and to reveal the significance levels and differences of these risks in the public-private healthcare sector. A total of 32 people consisting of board members, biomedical manager, contracted institutions manager, hospital manager, chief physician, nursing services manager, administrative services manager, human resources, finance, procurement, purchasing, IT managers working in two private, one public and one city hospitals operating in Istanbul were included in the sample of the study. While determining the sample set in question, judgemental sampling was used, and at this stage, data were collected by face-to-face interviews with the AHP (Analytic Hierarchy Process) questionnaire as a data collection method. In the analysis part of the study, Analytic Hierarchy Process (AHP) and Fuzzy AHP model were used with Microsoft Excel programme. The findings of the study show that the percentage values of human resources, clinical and patient safety, financial/financial, strategic and legal risks are higher in the main risk comparisons of private group hospitals. In addition, private group hospitals evaluated brand, marketing technological, environmental and natural disasters, supplier risk percentages lower than other risks. In the criteria comparisons of private group hospitals, service quality, management competence, reputation and financial structure were found to be highly important criteria. In addition, private group hospitals evaluated efficiency, productivity, leadership and accountability criteria at low importance. In the main risk comparisons of public hospitals, it was observed that the percentage values of clinical-patient safety, financial/financial, human resources and legal risks were higher. In addition, strategic, environmental risks-natural disasters, technological, supplier, brand and marketing risks were found to be lower than other risks in public hospitals. Service quality and accountability were found to be of high importance in the criteria of public hospitals. In addition, financial structure, management competence and effectiveness-efficiency criteria were rated high. Public hospitals evaluated reputation and leadership criteria as low compared to other criteria. As a result of the study, legal risks (25.9%), risks related to clinical and patient safety (14.7%), human resources risks (11.1%), environmental risks and natural disasters (10.5%), technological risks (8.5%), strategic risks (8.1%), marketing risks (6.8%), financial/financial risks (6.1%), brand risks (5.6%) and supplier risks (2.5%) were ranked in order of importance.
