Cost Differences Between Teaching and Nonteaching Hospitals for Older Adults Requiring Emergency General Surgery Procedures in the State of Maryland.

ABSTRACT

BACKGROUND: Older adults (OAs; ≥ 65 years) comprise a growing population in the United States and are anticipated to require an increasing number of emergency general surgery procedures (EGSPs). The aims of this study were to identify the frequency of EGSPs and compare cost of care in OAs managed at teaching hospitals (THs) vs nonteaching hospitals (NTHs). METHODS: A retrospective review of data from the Maryland Health Services Cost Review Commission database from 2009 to 2018 for OAs undergoing EGSPs was undertaken. Data collected included demographics, all patient-refined (APR)-severity of illness (SOI), APR-risk of mortality (ROM), Charlson Comorbidity Index (CCI), EGSPs (partial colectomy (PC), small bowel resection, cholecystectomy, operative management of peptic ulcers, lysis of adhesions, appendectomy, and laparotomy, categorized hospital charges, length of stay (LOS), and mortality. RESULTS: Of the 55,401 OAs undergoing EGSPs in this study, 28,575 (51.6%) were treated at THs and 26,826 (48.4%) at NTHs. OAs at THs presented with greater APR-ROM (major 25.6% vs 24.9%, extreme 22.6% vs 22.0%, P=.01), and CCI (3.1±3 vs 2.7±2.8, P<.001) compared to NTHs. Lysis of adhesions, cholecystectomy, and PC comprised the overall most common EGSPs. Older adults at THs incurred comparatively higher median hospital charges for every EGSP due to increased room charges and LOS. Mortality was higher at THs (6.13% vs 5.33%, P<.001). CONCLUSION: While acuity of illness appears similar, cost of undergoing EGSPs for OAs is higher in THs vs NTHs due to increased LOS. Future work is warranted to determine and mitigate factors that increase LOS at THs.
