Research Summary: Post-Acute Care Outcomes, Adherence Research. Vulnerable Populations Research

Dr. Watanabe seeks to determine factors that jeopardize appropriate medication use. Dr. Watanabe practices in Post-Acute Care Pharmacy and focuses on outcomes in older adults and residents of extended care facilities. He has completed investigations on 1) the role of adherence on surrogate markers for chronic conditions; 2) the effect of copayment and copayment pricing on adherence; 3) the impact of polypharmacy on adherence; 4) the role of pharmacy benefit on health services utilization; 5) methods used in health services research applying large national data; 6) new thresholds for categorizing adherent status.

Collaborating with an interdisciplinary care team, Professor Watanabe initiated longitudinal assessments of outcomes in Post-Acute Care Settings and characterized those at risk for poor adherence and compromised health outcomes in Veterans with chronic diseases. He has served as an invited speaker at several international forums devoted to improving care for seniors in long term care settings and provided presentations on pharmacy benefit and evaluation at the National Academy of Sciences. He currently trains students, post-docs, and practitioners in multiple disciplines in clinical research and post-acute care.

Professor Watanabe is a clinical consultant at the Program of All-inclusive Care for the Elderly (PACE) Clinic in San Ysidro, CA and the Villa Pomerado Skilled Nursing Facility in Poway, CA . He is an investigator on the Health Resources and Services Administration funded San Diego Geriatrics Workforce Enhancement Program Grant. Dr. Watanabe was the inaugural recipient of the University of Washington/Allergan Health Economics and Outcomes Research Fellowship. Watanabe serves as the faculty advisor for the Academy of Managed Care Pharmacy student chapter. He is a Board Certified Geriatric Pharmacist (BCGP).
