Research Summary: Post-Acute Care Outcomes, Adherence Research. Health Disparities Research
Dr. Watanabe seeks isolate the explanatory factors that jeopardize appropriate medication consumption. Dr. Watanabe practices in Post-Acute Care Pharmacy and focuses on outcomes in residents of extended care facilities. He has completed investigations to 1) evaluate the influence of adherence on surrogate markers for cardiovascular disease; 2) explore the effect of copayment and copayment pricing on adherence; 3) measure the influence of polypharmacy on adherence; 4) measure the influence of pharmacy benefit on health services utilization; 5) contrast methods used in health services investigations applying large national databases; 6) propose new thresholds for categorizing adherent status.
Collaborating with an interdisciplinary care team, Professor Watanabe has helped to initiate longitudinal assessments of outcomes in a variety of Post-Acute Care Settings and to characterize patients at risk for poor adherence and compromised health outcomes in Veterans populations 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. 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 San Diego 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. He is a Board Certified Geriatric Pharmacist (BCGP).
B.S. in Zoology (University of Washington); Pharm.D. (University of Southern California); M.S. (University of Washington); Ph.D. (University of Washington).
