The appropriateness of hysterectomy. A comparison of care in seven health plans. Health Maintenance Organization Quality of Care Consortium.

ABSTRACT

OBJECTIVE: To develop and test a method for comparing the appropriateness of hysterectomy use in different health plans. DESIGN: Retrospective cohort study. SETTING: Seven managed care organizations. PATIENTS Random sample of all nonemergency, non-oncological hysterectomies performed in the seven managed care organizations over a 1-year period. Patients who were not continuously enrolled in a plan for 2 years prior to their hysterectomy were excluded. MAIN OUTCOME MEASURES: Proportion of women undergoing hysterectomy in each plan for inappropriate clinical reasons according to ratings derived from a panel of managed care physicians. RESULTS: Overall, about 16% of women underwent hysterectomy for reasons judged to be clinically inappropriate. Only one plan had significantly more hysterectomies rated inappropriate compared with the group mean (27%, unadjusted). Adjusting for age and race did not affect the rankings of the plans and had little effect on the numeric results. CONCLUSION: The rates of inappropriate use of hysterectomies are similar to those for other procedures and vary to a small degree among health plans. This information may be useful to purchasers when they consider which health plans to offer their employees.
