Patient Characteristics Associated With Embolization Versus Hysterectomy for Uterine Fibroids: A Systematic Review and Meta-Analysis
Black and underinsured women in the United States are more likely than their counterparts to develop uterine fibroids (UFs) and experience more severe symptoms. Uterine artery embolization (UAE), a uterine-sparing therapeutic procedure, is less invasive than the common alternative, open hysterectomy. To determine whether demographic disparities persist in UF treatment utilization, we reviewed patient characteristics associated with UAE versus hysterectomy for UF among studies of US clinical practices. A systematic literature review was conducted via PubMed, Embase, and CINAHL (PROSPERO CRD42023455051), yielding 1,350 articles (January 1, 1995, to July 15, 2023) that outlined demographic characteristics of UAE compared with hysterectomy. Two readers screened for inclusion criteria, yielding 13 full-text US-based comparative studies specifying at least one common demographic characteristic. Random effects meta-analysis was performed on the data (STATA v18.0). Egger's regression test was used to quantify publication bias. Nine (138,960 patients), four (183,643 patients), and seven (312,270 patients) studies were analyzed for race, insurance status, and age as predictors of treatment modality, respectively. Black race (odds ratio = 3.35, P < .01) and young age (P < .05) were associated with UAE, whereas private insurance (relative to Medicare and/or Medicaid) was not (odds ratio = 1.06, P = .52). Between-study heterogeneity (I Knowledge of demographic characteristics of patients with UFs receiving UAE versus hysterectomy is sparse (n = 13 studies). Among these studies, which seem to be racially well distributed, Black and younger women are more likely to receive UAE than their counterparts.
