Firstly, it provides insights into patient satisfaction and experience, which are critical outcomes in healthcare delivery. Secondly, these data can be used to identify disparities in healthcare delivery and outcomes among different population groups, thus informing interventions to reduce health inequities. Finally, it allows for the monitoring of hospital performance over time, which is essential for continuous quality improvement.
