Description

This indicator measures the age-standardized rate of hysterectomy provided to patients in acute care hospitals or same-day surgery facilities, per 100,000 women age 18 and older.

For further details, please see the General Methodology Notes (PDF).

Background, Interpretation and Benchmarks

Rationale

As with other types of surgical procedures, variation in hysterectomy rates can be attributed to numerous factors, including differences in population demographics, physician practice patterns and availability of services. Utilization rates may reflect the level of uncertainty about the appropriate use of this surgical procedure. The right level of utilization is not known.
