Dr. Fendrick's research focuses on the clinical and economic assessment of medical interventions with special attention to how technological innovation influences clinical practice, benefit design, and health care systems. He has performed economic analyses of new interventions for several common conditions including: laparoscopic cholecystectomy, gastroesophageal reflux disease, arthritis/inflammatory conditions, viral infections, acute myocardial infarction, pediatric vaccinations, and cancer screening.
