Biography
Gwen Lapham, PhD, MPH, MSW, joined Kaiser Permanente Washington Health Research Institute (KPWHRI) in 2013 as an addictions health services researcher. Since then, she has capitalized on her prior social work and health services training to do impactful research on evidence-based primary care for unhealthy substance use, including alcohol, cannabis, and opioids. She has recently begun making strides in understanding cannabis use among primary care patients, including medical use and use among prenatal women.
Dr. Lapham recently completed the CATALyST K12 Washington Learning Health System Program funded by the Agency for Healthcare Research and Quality and the Patient-Centered Outcomes Research Institute. In the program, she partnered with Kaiser Permanente Washington health system leaders and with KPWHRI’s Center for Accelerating Care Transformation to address gaps in the quality of behavioral health care for children and adolescents by developing and testing an integrated approach to adolescent mental health. She expects this work to lead to new evidence for effective implementation of adolescent mental health integrated in primary care.
She is also a co-investigator of the Primary Care Opioid Use Disorders Treatment, or PROUD trial, a pragmatic implementation trial of nurse care management for treatment of opioid use disorders in primary care, as well as the Health Systems node of the National Institute on Drug Abuse Clinical Trials Network. Dr. Lapham’s research projects specific to cannabis include:
- A pilot study about the prevalence of and reasons for cannabis use among pregnant women. This study uses both cannabis screening results from the electronic health record (EHR) and qualitative interviews.
- Site principal investigator for a multisite study that examined patient-level and system-level factors associated with the Healthcare Effectiveness Data and Information Set, commonly known as HEDIS, to measure performance for initiation and engagement in treatment for patients with cannabis use disorders.
- Co-principal investigator for a study evaluating EHR documentation of medical use of cannabis. This study employs natural language processing methods to compare EHR data with data from confidential surveys about medical cannabis use.
Prior to working at KPWHRI, Dr. Lapham focused on qualitative and quantitative evaluation of preventive alcohol interventions in medical settings at the Veterans Health Administration in Seattle.
