6. Conclusions and implications
The objective of the current study is the development of a service quality instrument to monitor and improve the functional service quality aspects of primary health-care services provided by hospital outpatient departments in Greece. The findings, in accordance with those of Miranda et al. (2012), suggest that customers evaluate hospital outpatient service quality at an overall level, which is composed by four primary components: medical care, nursing care, administrative services and staff and facilities conditions. In particular, the results indicate that patients’ perception of service quality delivered by medical staff mostly contributes to the overall service quality perception. The perceptions about facilities and administrative services and staff effectiveness appear to be the second and third contributors to overall service quality assessment. Nursing care is the least significant contributor to perceived service quality formulation. This is in accordance with the findings of Otani et al. (2003) and Raposo et al. (2009) and can be attributed to the fact that, in hospital outpatient services, patients interact much more with physicians and administrative staff than with nursing staff. The proposed index can be used by mangers as a tool to measure the performance of services provided by hospital outpatient departments to determine their contribution on overall service quality perception and make the appropriate interventions towards improving overall services efficiency.
