Comparison of Rates of Hospitalization and Emergency Department Visits Using Self-Report and South Carolina Administrative Billing Data Among a Population-Based Cohort With Spinal Cord Injury

Our comparison of self-report and South Carolina administrative billing data hospitalizations and ED visits showed a significantly higher rate of reporting of hospitalizations using self-report, specifically among those with poor physical health and higher injury severity. Future work should look at different ways of asking about health care utilization and compare with South Carolina administrative billing data documentation to identify the best ways to assess through self-report.
