Effect of waiting time on patient satisfaction in outpatient: An empirical investigation

This study aimed to identify the effect of waiting time on patient satisfaction and the relationship between different types of waiting time. The questionnaire contained 2 parts. The first part included questions about expected waiting time (EWT), reasonable waiting time, tolerance waiting time, and basic personal information. The second part included perceived waiting time (PWT) and satisfaction evaluation. The actual waiting time (AWT) was recorded by the worker. Linear regression was used to analyze the influence of waiting time on satisfaction. Before data collection, this study was approved by the hospital's health ethics committee. In total, 323 questionnaires were collected, of which 292 (90.4%) were valid. The EWT, tolerance waiting time, rational waiting time, and PWT had a significant effect on patient satisfaction (P = .006, P = .043, P = .009, P = .000), whereas AWT had no significant effect on satisfaction (P = .365). The difference between the EWT and AWT had a significant effect on satisfaction (P = .000), while the difference between the PWT and AWT had a significant effect on satisfaction (P = .000). Age, educational background, gender, appointment, and hospital visit experience had no significant effect on patient satisfaction (P = .105, P = .443, P = .260, P = .352, P = .461, respectively). Patient satisfaction with waiting time was not directly affected by AWT, but by subjective waiting times. Furthermore, objective waiting time affects patient satisfaction through the subjective waiting time. Therefore, hospital managers can improve service quality by focusing on adjusting a patient's subjective waiting time while reducing the objective waiting time.
