Abbreviations: ER, emergency room; HCUP, Healthcare Cost and Utilization Project; IR, incidence rate; RR, relative rate; CI, confidence interval; NC, Not calculated a Incidence rates per 1,000 person-years.
bOnly HCUP categories with at least one increased RR (lower confidence limit >1.0) are presented. Results for HCUP categories with a significant decrease are located in Appendix Table 1. Bolded relative rate and confidence interval indicates the interval excludes 1.00. Bolded and highlighted relative rate and confidence interval indicates the double false-discovery rate adjusted p-value remains significant. Multiplicity adjustment limited to HCUP levels 1 and 2.
