Predictors of readmission to acute care during inpatient rehabilitation for non-traumatic spinal cord injury

Objectives: To investigate the frequency of and reasons for readmissions to acute care (RTAC) during inpatient rehabilitation (IPR) after non-traumatic spinal cord injury (NT-SCI). To develop a predictive model for RTAC using identified risk factors.Design: Retrospective case-control.Setting: Academic IPR hospital.Participants: Individuals with NT-SCI admitted to an academic SCI rehabilitation unit from January 2014-December 2015.Interventions: Not applicable.Main Outcome Measures: Readmissions to acute care services from IPR.Results: Thirty-seven participants (20%) experienced a RTAC for a total of 39 episodes. Thirty-five experienced 1 RTAC, while two had 2. The most common medical reasons for RTAC were infection (27%), neurological (27%), and noninfectious respiratory (16%). Multivariable logistic regression was used to develop a model to predict RTAC. Paraplegia was associated with 3.2 times increase in the odds of RTAC (P = 0.03). For every unit increase in FIM-Motor, there was a 5% reduction in the ...
