Trends in Various Types of Surgery for Hysterectomy and Distribution by Patient Age, Surgeon Age, and Hospital Accreditation: 10-Year Population-Based Study in Taiwan

Study Objective: To estimate the trends in various types of hysterectomy (abdominal, vaginal, laparoscopic, and subtotal) and their distribution according to patient age, surgeon age, and hospital accreditation in Taiwan. Design: Retrospective cohort study (Canadian Task Force classification II-2). Setting: Population-based National Health Insurance (NHI) database. Patients: Women with NHI in Taiwan undergoing various types of hysterectomy to treat noncancerous lesions. Interventions: Data for this study were obtained from the Inpatient Expenditures by Admissions files of the NHI research database, released by the NHI program in Taiwan for 1996-2005. Measurements and Main Results: A total of 234 939 women who underwent various types of hysterectomy were identified for analysis. The number of hysterectomies performed annually remained stationary during the 10-year study. Total abdominal hysterectomies decreased significantly (77.33% in 1996 vs 45.68% in 2005), laparoscopic hysterectomies increased signifi- cantly (5.20% vs 40.40%), vaginal hysterectomies decreased (14.70% vs 8.86%), and subtotal abdominal hysterectomies in- creased (2.76% vs 5.06%). Laparoscopic hysterectomy was more commonly performed in middle-aged women; vaginal hysterectomy wasmorecommoninolderwomen;andsubtotalabdominalhysterectomywasmorecommoninyoungerwomen. Laparoscopic hysterectomy was performed more commonly in regional hospitals (33.11%), followed by medical centers (30.17%) and local hospitals (17.78%). Laparoscopic hysterectomy was performed more commonly in not-for-profit hospitals (30.25%), followed by private hospitals (29.32%) and government-owned hospitals (25.91%). Conclusion: There has been considerable change in the types of surgery used for hysterectomy in Taiwan over the past 10 years. As a minimally invasive approach, laparoscopic hysterectomy represents a profound change for both patients and surgeons. Journal of Minimally Invasive Gynecology (2010) 17, 612-619 2010 AAGL.
