Quality Assessment of Services in Primary Healthcare in Iran: A Systematic Review and Meta-analysis

BACKGROUND: Primary healthcare (PHC) plays an important role in achieving universal health coverage (UHC). The SERVQUAL instrument is the tool for evaluating the quality of services in the health sector. The main purpose of this study is to evaluate the quality of services provided in PHC in Iran using the SERVQUAL instrument. MATERIALS AND METHOD: We searched eight databases from January 2000 to September 2021. We analyzed the mean of various SERVQUAL instrument items using the DerSimonian-Laird approach via a random model with 95% confidence interval. Also, we used I2 to evaluate the heterogeneity of the studies. RESULTS: Finally, 17 studies were chosen for analysis in the present study. There were 8,767 study participants, out of which 8,237 were female and 530 were male. The mean dimensions of perception were as follows: Tangibles = 3.71, reliability = 4, responsiveness = 3.79, assurance = 3.83, and empathy = 3.86. For the expectation, the mean dimension were: Tangibles = 4.46, reliability = 4.46, responsiveness = 4.36, assurance = 4.36, and empathy = 4.36 respectively. The total gap quality between perception and expectation was -0.53. CONCLUSION: All dimensions of quality based on SERVQUAL were negative, and the quality of service in PHC is not satisfactory. Therefore, policymakers must adopt serious and effective programs to improve services in this area. We also recommend that quality management of services in PHC in Iran should move toward comprehensive optimization in all areas, and quality in this area should be a priority.
