Factors associated with post-acute functional status and discharge dispositions in individuals with spinal cord injury.

Background: Research has evaluated the effect of surgical timing on patient functional recovery in individuals with spinal cord injury (SCI); however, there is a critical need to assess how demographics, clinical characteristics, and process of care affect functional outcomes.
Objective: We examined the association between demographic, clinical, and process of care factors with post-acute functional status (locomotion and transfer mobility scores) and discharge disposition (home vs. institution) in individuals with SCI.
Methods: This study was a retrospective cohort analysis of the Pennsylvania Trauma Systems Outcomes Study (PTOS) database for individuals with traumatic SCI ( N  = 2223). We conducted multinomial and binomial logistic regression analyses to examine post-acute functional status and discharge disposition, respectively.
Results: The results indicated that older age, longer length of stay, lower Glasgow Coma Scale (GCS), higher Injury Severity Score (ISS), and individuals with tetraplegia had significantly lower motor functional score at discharge from an acute hospital. In addition, older age, individuals with public-sponsored insurance, longer length of stay, lower GCS, and higher ISS had significantly higher odds of being discharged to an institution, as compared to home. Individuals of Hispanic ethnicity, as compared to White, had lower odds of being discharged to an institution.
Conclusions: The regression models developed in this study were able to better classify discharge destinations compared to the functional outcomes at discharge from the acute hospital. Further research is necessary to determine how these factors and their associations vary nationally across the US, which have the potential to inform trauma and acute care post-SCI.
