Nowadays, the Tunisian hospital environment is a complex organization in which the safety of the patient is of primary concern to the authorities. In our study we focus on the Obstetrics and Gynecology Department of CHU of Sfax. It should be noted that no risk management study dealt with the hospital logistic chain in this institution. Hence, the purpose of this paper is to develop a strategy targeting the control of risks related to the patient care activities. The proposed approach consists of two phases. First, a qualitative survey, based on 20 semi-structured interviews, is carried out to identify the problems related to care and logistic activities of the Obstetrics and Gynecology Department in CHU Sfax. Second, the assessment of the identified risks in the hospital context is a multicriteria decision problem. To perform the evaluation of the 12 objectives depending on the identified risks, we have chosen the AHP (Analytic Hierarchy Process) for its simplicity and flexibility.
