IntroductionHypertensive patients' failure to refer to health centers for the management of their disease is the most fundamental public health challenge in most societies. The aim of this study was to identify the utilization obstacles to hypertension services provided at comprehensive health centers (CHCs) from the perspective of patients and the staff of health centers.MethodsThis was a qualitative study using conventional content analysis which was conducted in 2022. Participants included 15 hypertensive patients referring to CHCs and 10 staff (including personnel of CHCs and expert staff) of Ahvaz Jundishapur University of Medical Sciences, Ahvaz, southwest of Iran. Data were collected using semi-structured interviews. Interviews were analyzed using content analysis method, and coding was done manually.ResultsIn total, 15 codes and 8 categories were extracted from the interviews which were organized in two main themes of "individual problems" and "systemic problems". More particularly, the main theme of “individual problems” involved attitudinal obstacles, occupational obstacles, and economic obstacles. The main theme of "systemic problems" included educational obstacles, motivational obstacles, procedural obstacles, structural obstacles, and managerial obstacles.ConclusionIn order to address individual problems associated with the patients' failure to refer to CHCs, we need to take appropriate measures. These include using motivational interviewing techniques and utilizing the effective activity of healthcare liaisons and volunteers in CHCs to increase patients' awareness and change their negative attitudes and misconceptions. To solve systemic problems, it is imperative that effective training courses be held for health center staff.
