Session Title: AA 2022 Posters - Neurological Rehabilitation
Session Time: None. Available on demand.
Background and/or Objectives: To investigate predictors of wound outcomes at 1 year of discharge of Veterans with spinal cord injury (SCI) hospitalized with one stage 3 or 4 pelvic pressure injury (PI).
Design: Retrospective medical record review between 1/1/2013-12/31/2018.
Setting: A VA HealthCare System SCI unit.
Participants: Veterans with SCI admitted with one stage 3 or 4 pelvic PI. Traumatic and atraumatic SCI patients treated medically without flap surgery were included.
Interventions: Wound care
Main Outcome Measures: Wound status at one year of discharge. A logistic model was built to select the significant predictors of wound healing outcomes. The area under the curve (AUC) was calculated using the leave-one-out cross validation method. P < 0.05 was considered statistically significant.
Results: A total of 62 hospitalizations were included for analyses: 33 healed, and 29 non-healed wounds. Three significant predictors of non-healed wound outcomes include: pressure mapping protocol during hospitalization, wound depth, and usage of alginates dressings. Two significant predictors of healed wound outcomes include: animal-based tissue and hydrocolloid dressings. The AUC of this logistic regression model is 79.98%.
Conclusions: The five wound outcome predictors are the depth of the wound, and clinical decision-making factors regarding seating and wound treatments. Pressure mapping protocol correlated with other variables that could not serve as a predictor by themselves including higher neurological level of injury and lack of manual pressure relief techniques. The clinical decision having a patient pressure mapped predicts that the wound may not heal at one year of discharge. The three wound treatment product predictors may represent characteristics of the wound. Further investigation on these clinical decision-making factors is warranted in utilizing treatment and healthcare recourses for SCI individuals hospitalized with PI.
