Robert Penfold, PhD, is a health services research and health policy expert whose work focuses on developing and testing strategies to optimize behavioral health care delivery and patient outcomes—particularly in children and adolescents. His research addresses practical issues, such as how to reduce unnecessary use of antipsychotic medications in youth. He also studies the effects of cost-control policies on how clinicians deliver care, how people use care, and how those changes can promote or worsen their health.
Dr. Penfold is a co-investigator in the Mental Health Research Network (MHRN), a resource for studies on mental health conditions ranging from autism to postnatal depression. He leads the MHRN’s child and adolescent scientific interest group. He is also investigating reasons why similar patients receive different mental health treatment, such as different medications, depending on where they live or receive care.
His other recent and ongoing projects include:
Dr. Penfold has extensive experience gathering and analyzing information from large health databases, including those of Medicare, Medicaid, and the Health Care Systems Research Network’s Virtual Data Warehouse. These data and analyses allow rapid information sharing among Kaiser Permanente Washington and participating sites, which improves patient safety and timely access to effective, cutting-edge therapies.
He has also conducted several novel pragmatic clinical trials using the Epic electronic health record system.
Before joining KPWHRI in 2010, Dr. Penfold held research and teaching positions at Nationwide Children's Hospital in Columbus, Ohio; the Winnipeg Regional Health Authority; the Manitoba Centre for Health Policy; and most recently, at Harvard Medical School in the Department of Population Medicine and Harvard Pilgrim Health Care Institute.
