This study investigates the impact of intra-organizational information, midwifes’ job satisfaction, and performance assessment on midwifes’ services quality. The questions are empirically tested with survey data obtained from 276 midwives, specialist doctors, and nurses and mothers who recently gave birth in a cross-section of Iranian public healthcare organizations. The results from a structural equation model suggest that improved performance assessment system leads to higher the midwifes’ services quality. In addition, the results indicate that midwifes’ job satisfaction and intra-organizational information increases the midwifes’ services quality, both directly and indirectly, through the mediating effect of performance assessment system. Our study contributes to the growing research exploring the interface between accounting and health issue by recognizing the importance of performance assessment system of midwifery services via balanced scorecard framework for understanding midwifes’ services quality.
