Following the increases in the number of hospitals in Jordan, the quality of health care services provided to patients affects hospital performance under severe competition. Customer defines how a firm determines requirements, expectations and customer performance and investigates the procedures undertaken by the firm to acquire information about current and future customers (Lee et al., 2003). ISO 9000 certification enforces firms to meet or exceed customer expectations and have activities designed to increase customer focus (Al-Refaie et al., 2011). Patient satisfaction is considered an important measure of the quality of health care services and a key determinant of patients’ behavioral intention. By including the patient perspective as to how well the health care services meet or exceed patient’s expectations, managers can identify the service design and delivery improvements that contribute to patient satisfaction and revisit intention. For this purpose, it is necessary to evaluate quality of health care services from patient perspective.
