Abstract
STUDY OBJECTIVE: To investigate rates of utilization of alternative treatments before hysterectomy for benign gynecologic indications within a large integrated health care system. DESIGN: Retrospective cohort study of patients who underwent hysterectomies for benign gynecologic conditions between 2012 and 2014 (Canadian Task Force classification II-2). SETTING: Kaiser Permanente Northern California, a community-based integrated health system. PATIENTS: Women who underwent hysterectomy for a benign gynecologic condition between 2012 and 2014. INTERVENTIONS: From an eligible cohort of 6892 patients who underwent hysterectomy, a stratified random sample of 1050 patients were selected for chart review. Stratification was based on the proportion of indications for hysterectomy. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the use of alternative treatments before hysterectomy. Alternative treatments included oral hormone treatment, leuprolide, medroxyprogesterone intramuscular injections, a levonorgestrel intrauterine device, hormonal subdermal implants, endometrial ablation, uterine artery embolization, hysteroscopy, and myomectomy. Of the 1050 charts reviewed, 979 (93.2%) met the criteria for inclusion in this study. The predominant indication for hysterectomy was symptomatic myomas (54.4%), followed by abnormal uterine bleeding (29.0%), endometriosis (5.8%), pelvic pain (3.1%), dysmenorrhea (3.4%), and other (4.3%). The major routes of hysterectomy were laparoscopy (68.7%) and vaginal hysterectomy (13.4%). Before hysterectomy, 81.2% of patients tried at least 1 type of alternative treatment (33.8% with 1 treatment and 47.4% with at least 2 treatments), and 99.3% of patients were counseled regarding alternative treatments. Compared with younger women age <40 years, women age 45 to 49 years were less likely to use alternative treatments before hysterectomy (adjusted odds ratio, 0.41; 95% confidence interval, 0.21-0.76). There were no variations in treatment rates by socioeconomic status or between major racial and ethnic groups. The final pathological analysis identified myomas as the most common pathology (n = 637; 65.1%); 96 patients (9.8%) had normal uterine pathology. CONCLUSION: More than 80% of patients received alternative treatments before undergoing hysterectomy for a benign gynecologic condition. Additional investigation is warranted to assess alternative treatment use as it relates to preventing unnecessary hysterectomies.
