The research findings suggest that the board of directors and managers are the key decision-makers in human resource management. Hospital managers can aid in decision-making by providing resources, including human resources. The board of directors can influence the hospital's focus by intervening in decisions (
24,
25). These results are consistent with the research findings of Ancarani et al. (
26), Schubert and Willems (
27), Seyedin et al. (
28), and Jafari et al. (
23), but differ from Rayburn, J. M. and Rayburn, L.G.'s study (
29), which considers physicians to be the main factor in the hospital's power structure, and Pauly and Redisch's study (
21), which also identifies physicians as the primary decision-makers. Additionally, this study disagrees with Xie et al.'s (
30) suggestion that government intervention is necessary for hiring and firing hospital employees, and with Doshmangir et al.'s (
31) findings that hospitals lack the authority to determine their required staff numbers. In Iran, universities are responsible for hiring and firing employees, while hospitals and their managers have limited involvement.
