To explore basic characteristics and hospital-based outcomes of subjects receiving uterine artery embolization (UAE) as the principal procedure for an inpatient admission. Data from the National Inpatient Sample 2012–2015 comprising up to 97% of US hospitals was used. Admissions with uterine artery embolization with or without coil as the principal procedure were identified using the ICD-9 procedure codes. Basic demographic and financial variables were extracted. Outcomes were compared based on hospital characteristics. Included patients had an average age of 44.2 (SE: 0.3) and were mostly located in large central metro areas (51.8%). Overall, 45.1% identified as black, 30.5% as white, and 13.6% as Hispanic. The primary payer in the majority of admissions were private insurance and health maintenance organizations (57.8%) compared to 24.5% Medicare and 7.6% Medicaid. Most of the patients were classified in the minor risk group for loss of function (52.1%) and mortality (80.1%). No significant variation in case severity, mortality (1.0% SE 0.3%), length of stay (3.3 days SE 0.1) or routine disposition (92.4% SE 0.8%) was found based on hospital characteristics. However, total charges were significantly higher at private investor-owned hospitals (74,876$ vs 59,047$ at nonprofit and 44,835$ at government-owned hospitals; P<0.05), hospitals that were larger (60,501$ vs 44,261 for small hospitals; P<0.05) and hospitals at West region (69,241$ vs 54,334$ at Northeast; P<0.05). Despite similar outcomes of mortality, length of stay and disposition, significant differences exist in total charges for uterine artery embolization admissions based on hospital ownership (private vs non-profit vs government owned), size (large vs medium and small) and region (west vs northeast).Tabled 1RegionCost USD (SE) NE54,336 (3796) MW56,540 (3531) S57,781 (3536) W69,241 (3475)Bed Size Small44,261 (2963) Medium57,993 (3747) Large60,501 (2469)Ownership Government44,835 (3275) Nonprofit59,047 (2335) Private74,876 (3347) Open table in a new tab
