KT Park, MD, is an Assistant Professor in the Department of Pediatrics Division of Pediatric Gastroenterology.  His training, research experience, and interests are in health services research, especially as it relates to the following:

  • Cost and cost-effectiveness analyses to inform value-based care (e.g., pharmaco-economic studies, comparing diagnostic or therapeutic strategies)
  • Analysis of longitudinal datasets / databases (e.g., health care utilization studies, race/SES disparity studies)
  • Network quality-improvement (QI) research and/or point-of-care (POC) intervention studies (e.g., individualized or patient-specific care protocols)
  • Generating patient-reported outcomes (PROs) from social media, EHR (or patient-health portals), and automated electronic surveys to inform clinical practice or policy needs (PROs including patient-activation measurements, health-monitoring data, and quality-of-life and pain scores, etc.)
  • Access of health care studies using technology (e.g., telehealth / telemedicine, webportals)
