Trends in the National Distribution of Laparoscopic Hysterectomies From 2003 to 2010

Study Objective: The purpose of this analysis was to compare the trends in undergoing laparoscopic hysterectomy (versus abdominal or vaginal hysterectomy) based on patient age, race, median income and insurance type, from 2003 to 2010. Design: Retrospective study (Canadian Task Force classification II-3). Setting: National sample of hospital admissions after hysterectomy. Patients: Health Cost and Utilization Project-Nationwide Inpatient Sample database was used to review records of women who underwent hysterectomy for either menorrhagia or leiomyoma from 2003-2010. Intervention: The predicted probability of undergoing laparoscopic hysterectomy was determined for each year according to patient age, race, median income, and insurance type. The slopes of these values (i.e. the trend) was compared for each subgroup (i.e. black, white, Asian, etc.) in these categories. Main Results: A total of 530, 154 cases were included in this study. Total number of hysterectomies decreased by 39% from 60,364 to 36,835 from 2003 to 2010. The percent of hysterectomies that were laparoscopic increased from 11% in 2003 to 29% in 2010. All groups analyzed experienced an increase in predicted probability of undergoing a laparoscopic hysterectomy. Of all women undergoing hysterectomy, the probability of undergoing a laparoscopic hysterectomy remained highest for women who were less than 35 years old, white, with the highest median income, and with private insurance from 2003-2010. The slope was significantly greater for (1) white females versus all other races analyzed (p<0.01), (2) females in the highest income quartile versus females in the lowest income quartile (p<0.01) and (3) females with private insurance versus females with Medicaid (p<0.01) or Medicare (p<0.01). Conclusions: There remains a gap in distribution of laparoscopic hysterectomies with regards to age, race, median income and insurance type that does not seem to be closing, despite the increased availability of laparoscopic hysterectomies.
