Health Services Research

To advance emergency care through diverse projects
in health services research


The Health Services Research Program (HSR) includes both observational and interventional studies. Examples include:

  1. Studies based on, or derived from, the National Emergency Department Inventory (NEDI) project (e.g., NEDI-USA, NEDI-State), and
  2. Analyses of emergency care in large administrative datasets (e.g., AHA, KID, Medicare, NEDS, NHAMCS, NHDS, NIS, SEDD/SID)
Major Research Themes
  • Health insurance
  • Patient safety
  • Access to emergency care (e.g., what/where are EDs; findERnow app)
  • ED workforce (including MLPs), Choosing Wisely
  • Opioid epidemic
  • Pediatric Emergency Care Coordinator (PECC)
  • Telemedicine
  • Hospital networks (eg, stroke transfers)
  • Health-related social needs (HRSN) screening
  • COPD readmissions
  • Health disparities
