There are various methods and tools used to measure the quality of medical services. Commonly used metrics include patient satisfaction surveys, clinical outcome indicators, process indicators, and healthcare utilization rates. Patient satisfaction surveys capture patients' perceptions of care quality. Clinical outcome indicators, such as mortality rates, infection rates, and complication rates, provide objective measures of health outcomes. Process indicators assess whether specific healthcare practices are performed according to established guidelines. Healthcare utilization rates, including hospital readmissions and emergency department visits, can also reflect the quality of care provided.
