Dr. James Feinstein is an Assistant Professor in the Division of General Pediatrics at the University of Colorado School of Medicine. Under the mentorship of Chris Feudtner, MD PhD MPH, and Allison Kempe, MD MPH, Dr. Feinstein has trained as a health services researcher and developed expertise with observational study design, large data analytic methods, secondary data analysis, and statistical programming. Dr. Feinstein has pursued a research career initially focused on palliative care and children with complex chronic conditions (CCCs). In collaboration with Dr. Feudtner, Dr. Feinstein has authored a revision of the widely used classification scheme to identify children with CCCs. They have also collaborated on a study quantifying pediatric exposures to drug-drug interactions in US children’s hospitals. As Dr. Feinstein’s clinical roles have evolved to the outpatient care of children with CCCs and special medical needs, his research interests have also increasingly focused on the outpatient setting. Over the past year, Dr. Feinstein has begun assembling a research portfolio focused on outpatient medication safety and management for pediatric patients, specifically regarding children with CCCs. He authored a study quantifying outpatient adverse drug events associated with national emergency department visits, and has been working with Medicaid data to characterize patterns of medication exposure in infants and children. Dr. Feinstein’s long-term career goals are to improve medication safety and health outcomes for children with polypharmacy, with a focus on implementing and evaluating technology-based strategies to improve signal detection of adverse drug events in children with CCCs.
