  1. Variation in hysterectomy rates across small geographic areas of Massachusetts.

    Article - En anglais

    OBJECTIVE

    Our objective was to determine whether small-area variation in hysterectomy rates exists within Massachusetts and, if so, whether regions with persistently high or low rates can be identified.

    STUDY DESIGN

    By examining data derived from standardized hospital discharge forms between 1982 and 1989, we compared hysterectomy rates among 172 small geographic areas within Massachusetts.

    The ratios of actual to expected number of hysterectomies for each area were also computed.

    Statistical significance of rate variation was established by a value of p<0.01 (khi2 test).

    RESULTS

    The hysterectomy rate per 1000 women varies fivefold across small-population areas of Massachusetts.
