  1. CI confidence interval, ED emergency department, IP inpatient, NSP needle and syringe programs, OP outpatient, PWID people who inject drugs, SSTVI skin, soft tissue, and vascular infections
  2. aThe number of events refers to the total number of deaths or contacts with the healthcare system per 100,000 PWID over a 5-year period
  3. bIncidence rates were calculated as the number of events per 1000 population for SSTVI mortality and the number of events per 1000 person-years for contacts with the healthcare system
