Prevalence of chronic health conditions and hospital utilization in adults with spinal cord injury: an analysis of self-report and South Carolina administrative billing data.

STUDY DESIGN: Retrospective analysis of self-report and administrative billing data.

OBJECTIVES: (1) Identify the self-reported prevalence of seven chronic health conditions (CHCs) in adults with chronic, traumatic spinal cord injury (SCI), (2) Examine the relationships between the presence of CHC with future hospital admissions and total number of inpatient days and (3) identify predictors of utilization.

SETTING: Data were collected from participants living in and utilizing hospitals in South Carolina, USA.

METHODS: Participants were identified through the South Carolina SCI Surveillance System Registry. Between 2010 and 2013, 963 adults ( > 18 years old) with chronic ( > 1-year), traumatic SCI completed self-report assessments (SRAs); this analysis includes data from 787 individuals. The presence/absence of the seven CHC was assessed using self-report data. Administrative billing data were used to assess hospital utilization in non-federal, South Carolina hospitals in the year following the SRA.

RESULTS: In all, 40.5% reported no CHC; 23.4% reported one CHC and 36.1% reported having two or more CHC. The most commonly reported CHCs were hypertension (43.1%), high cholesterol (32.2%) and diabetes (15.8%). In total, 59% had at least one hospital admission in the year following the SRA (mean 3 ± 5; range 0-45; median = 1). The mean total inpatient days was 15.7 ± 43 days (range 0-365; median = 1). Predictors of hospital admission included CHC, pressure sores, education, prior hospitalization and injury severity. With the exception of CHC, each was also associated with total number of inpatient days.

CONCLUSIONS: CHC are prevalent and associated with hospital admissions in adults with chronic, traumatic SCI.
