摘要:BACKGROUND: Discrimination in health care is a common phenomenon whose complete understanding has always been a major concern of health-care systems to control and reduce it. This study aimed to explore the experiences of unintentional discrimination and related factors in health-care providers. MATERIALS AND METHODS: This qualitative study was conducted with a content analysis approach in 2019. Data were collected through semi-structured interviews with 13 health-care providers including two physicians, three nursing supervisors, two head nurses, four staff nurses, and two nurse aides in two general hospitals in Tehran, Iran. Participants were selected through purposeful sampling. The obtained data were analyzed by Graneheim and Lundman method. RESULTS: Three main categories and eight subcategories were obtained from the data analysis: (1) forced discrimination (superiors’ pressures and executive orders, occupational concerns, and fear of the superiors); (2) guided discrimination (professional challenges, managers’ policymaking, and lack of medical ethics knowledge); and (3) lack of resources (workforce shortage and lack of medical equipment). CONCLUSION: The results of this study suggest that health-care providers such as doctors and nurses are unintentionally forced to provide discriminatory care on some occasions. Knowing and managing these unwanted factors can partly counteract unintentional discrimination. Thus, preventing the factors that lead to superiors’ pressures and occupational forces and improving the medical ethics knowledge should be considered by health-care managers.
