Julie A. Schmittdiel, PhD, is a Research Scientist at the Kaiser Permanente Northern California Division of Research. She holds a bachelor’s degree in Mathematics from the Massachusetts Institute of Technology, and an MA in Biostatistics and a PhD in Health Services and Policy Analysis from the University of California at Berkeley. Dr. Schmittdiel’s career focuses on stakeholder engagement and translational research in diabetes and cardiovascular disease, with a particular focus on improving medication adherence and cardiovascular disease risk factor control in diabetes patients. She has been principal or co-investigator on more than 20 delivery science and health policy research studies, and has published more than 100 papers in peer-reviewed journals. Dr. Schmittdiel serves as the Director of the National Institutes of Health-funded Health Delivery Systems Center for Diabetes Translational Research, and is the Associate Director of the Kaiser Permanente Delivery Science Fellowship Program.

Areas of Focus

  • Translational research in diabetes prevention and care
  • Stakeholder engagement
  • Learning health care systems
  • Health care services research and delivery science
  • Evaluation of natural experiments in health care

Current Work

My work focuses on pragmatic research and clinical trials to improve diabetes care and prevention within learning health care systems. I currently serve as the PI of two NIDDK-funded R18 grants in this area. The EMPOWER (Encouraging Mail Order Pharmacy Use with Every Refill) (1R18DK104249-01A1) study is a cluster-randomized trial to determine if improving access to mail order pharmacy use within the KP population can improve medication adherence and blood sugar control while reducing disparities in diabetes care. The UPSTART (Using Peer Support To Aid in Prevention and Treatment in Prediabetes) (1R18DK113403) study is a newly-funded randomized controlled trial study that will examine whether providing peer support and engagement to patients with prediabetes can improve health care behaviors, and reduce the incidence of diabetes in this high risk, vulnerable population.
