  1. CI confidence interval, ED emergency department; HR = hazard ratio; IP = inpatient; IPC = inpatient complications; NSP = needle and syringe programs; OP = outpatient; PDD = patient-directed discharge; SSTVI = skin, soft tissue, and vascular infections
  2. aFor SSTVI mortality, we conducted a competing risk analysis using the Fine-Gray model to derive the hazard ratio
  3. bFor health service use, we conducted a recurrent event analysis using the marginal mean model to derive the hazard ratio
