The study was a qualitative research method. In this research, depth and semi-structured interviews were carried out and purposive sampling was used. The study population were top managers of Amin and Alzahra hospitals. Sampling was started with the first participant until saturated level of information, participants completed the 8 cases. According to interviews, the current role and contribution of non-university institutions [e.g. municipalities representatives] in hospital board of trustees is neither bold nor transparent. These hospitals can address minimum changes in their mechanisms of accountability after developing board of trustees. It is rational for hospitals as they undergo organizational reform and developing board of trustees, to have more rights for decision making. Further more, their accountability mechanism should change accordingly
