Risk factors and acute in-hospital costs for infected pressure ulcers among gunshot-spinal cord injury victims in southeastern Michigan

Background Management of pressure ulcers (PrUs) in patients with gunshot-spinal cord injuries (SCIs) presents unique medical and economic challenges for practitioners. Methods A retrospective chart review was conducted at 3 acute care hospitals in metropolitan Detroit for patients admitted with PrUs due to gunshot-SCIs between January 2004 and December 2008. Multivariate analysis using logistic regression was conducted to choose for the independent predictors of infected PrUs. Mean adjusted in-hospital costs per patient and per hospitalization were calculated and compared between infected and noninfected PrUs. Results The study cohort included 201 gunshot-SCI patients with PrUs contributing to 395 admissions, including readmissions, between 2004 and 2008. Seventy-six patients (38%) had infected PrUs at time of the index admission. Independent predictors of infected PrUs on index admission included Charlson Comorbidity Index ≥2 (odds ratio, 2.18, P = .026) and stage III/IV PrU (odds ratio, 4.82; P
