Objective: The purpose of this study is to investigate predictors of pressure injury (PrI) outcomes at one year after discharge for Veterans with spinal cord injury (SCI) hospitalized with a Stage 3 or 4 PrI. Design/Setting/Participants: This is a retrospective medical record review from one VA Health Care System SCI unit. Participants were Veterans with traumatic or non-traumatic SCI admitted with one Stage 3 or 4 pelvic PrI treated medically (e.g. without flap surgery). Logistic models were used to select the significant predictors of PrI healing outcomes. Outcome Measure: One year after discharge wound outcomes (healed vs non-healed) for Veterans with SCI hospitalized with a Stage 3 or 4 PrI. Results: A total of 62 hospitalizations were included for analyses resulting in 33 healed and 29 non-healed PrIs. Three significant predictors of non-healed PrI outcomes included use of pressure mapping during hospitalization, greater PrI depth, and usage of alginate dressings. Two significant predictors of healed PrI outcomes included the use of animal-based tissue and hydrocolloid dressings. Area under curve of this logistic regression model was 79.98%. Conclusion: The clinical decision of having a patient pressure mapped predicts that the PrI may not heal at one year of discharge. Pressure mapping protocol correlated with another variable that could not serve as a predictor by itself, including using powered pressure relief techniques. The three PrI treatment predictors may represent characteristics of the PrI itself, rather than the efficacy of the product. Further investigation on these clinical decision-making factors is warranted to ensure efficient and cost-effective treatment strategies for individuals with SCI hospitalized with PrIs.
