  • Background: Limited data exists on hospital costs attributable to infected pressure ulcers  in gunshot wound (GSW) victims who are paraplegic .

    Methods: Patients admitted to three acute care hospitals in metro Detroit from January 2004 through December 2008 were included if they met the following criteria: age > 14 years, paraplegia following a gunshot wound, and presence of a pressure ulcer.  Medical records were reviewed. Total costs included cost of initial admission and subsequent readmissions for the following one year after each initial patient admission.

    Results: 201 total patients with 411 total hospital admissions were included.  Mean age was 37 ± 8.9; 179 (89%) were male; 191 (95%) were African-American; and 104 (52%) were receiving Medicaid or Medicare.  Most patients were admitted from home (n=169, 84%) or a nursing home (n=21; 10%). Infection of a pressure ulcer was confirmed in 76 cases (38%) during the initial admission, and was more common in stage III - IV ulcers (61/113, 80% were infected) compared to stage I - II ulcers (n=15/88, 20%)(p<0.001). 90 (45%) patients had > 1 readmission in the first year following their initial admission.  Risk of readmission was significantly higher for patients with infected ulcers (57%) compared to those without (38%) (OR: 2.2, 95%CI: 1.2, 3.8). Total hospital costs per patient were highly skewed with a mean of $16,951 ± $30,030.6 and a median of $9,217.5 (IQR $4344-$19864).  Median total hospital costs were greater among patients with infected ulcers, (median$10,007.3(IQR:$4907-$20825.5)  compared to those without (median $8342.9 (IQR:$3715-$17509)(p=0.2).  Four patients accounted for extremely high costs attributable to prolonged hospital stay and multiple surgical procedures; two had infected pressure ulcers.

    Conclusion: Infected pressure ulcers among GSW victims with paraplegia accounted for almost $3 million dollars and 2500 hospital days during the study period.  Measures to prevent the development of pressure ulcer and associated super-infection this population would be cost-effective.
