Impact of race and ethnicity on length of stay, discharge location, and total charges for inpatients with skin ulcers in New York

Background Black patients receiving outpatient care for skin ulcers are less likely to see a physician and are at risk for higher stage pressure injuries. While racial/ethnic differences in outpatient treatment of skin ulcers have been described, this study aims to elucidate potential differences in the inpatient setting using publicly available data. Methods We conducted a retrospective cohort study of the Statewide Planning and Research Cooperative System database, a de-identified, patient-level dataset for inpatient visits in New York between 2009 and 2021. Admissions were filtered by diagnosis-related group (APR-DRG) code 380 (skin ulcers). Results Compared to non-Hispanic white patients, non-Hispanic black patients demonstrated longer mean LOS (8.15 vs. 7.48 days, p = 0.009), higher mean charges ($44,400 vs. $37,600, p < 0.001), and were more frequently discharged home without services (38.1% vs. 32.4%, p < 0.001). Black Hispanic patients had similar mean LOS (7.22 vs. 6.36 days, p = 0.133), similarly discharged home without services, and had higher mean charges ($45,800 vs. $36,700, p = 0.031). After adjusting for patient factors, non-Hispanic black patients had a longer LOS by 0.26 days ( p = 0.028) with $2331 higher inpatient charges ( p = 0.001) compared to non-Hispanic white patients. Conclusions The findings suggest racial and ethnic differences in hospitalizations for skin ulcers, with black patients experiencing greater LOS and charges. The reasons for these differences merit investigation, yet could be related to delays in outpatient care, more severe disease, presence of comorbid conditions, or complications requiring intensive inpatient services.
