What does the term 'incidence' refer to in quality measures?

• A. The rate of new patient admissions.
• B. The direct evidence of the quality of care provided.
• C. The hospital's accreditation status.
• D. The average length of stay.

Answer: (B)

Incidence in quality measures is the rate at which new events occur in a defined population during a specified time period. Focusing on new cases makes it a direct signal of how often problems arise under care. For example, counting new hospital-acquired infections per 1,000 patient-days shows how effectively infection-prevention practices are working. A higher incidence points to potential quality issues, while a lower incidence suggests better quality. This differs from metrics like the rate of new admissions, which tracks patient flow; accreditation status, which is a certification; or average length of stay, which reflects efficiency rather than the occurrence of new adverse events.
