Jeffrey L. Fellows, PhD

Jeffrey Fellows, PhD, is a health economist with over 20 years of experience implementing and evaluating community-based and clinical practice-based research. His research has focused on two primary themes: expanding the evidence base in dentistry and dental practice and contributing to the understanding and reduction of the disease burden of smoking in communities and health system populations. He was an associate section editor for the 2021 NIH report on Oral Health in America: Advances and Challenges, focusing on the oral health workforce, education, practice, and integration, and authored an accompanying article in the Journal of the American Dental Association (June 2022) on the implications of the report for dental practice. He was a contributing author for the 2004 Surgeon General’s Report Health Consequences of Smoking.

Dr. Fellows is the director of the Western Region of the National Dental Practice-Based Research Network (PBRN), a collaborative of over 8,000 U.S. dental practitioners, researchers, and stakeholder organizations. From 2005 to 2012, he was the Permanente Dental Associates’ regional director for the Dental Practice-Based Research Network, which preceded the National Dental PBRN. Dr. Fellows has led PBRN studies of post-endodontic pain, the incidence and risk factors for osteonecrosis of the jaw, thresholds to initiate restorative caries treatment, and pay-for-performance in dentistry.

He led two PBRN COVID-19 studies related to dental practitioners’ experiences with infection control measures in dental offices and with dental office readiness to provide vaccinations. He also has conducted research testing organizational strategies to increase sealant placement rates, clinic interventions to reduce tobacco use among dental patients, and medical-dental integration. He is currently a co-investigator on a large data system study to estimate periodontal risks for men and women with and without type 2 diabetes, leading to the development and testing of risk-prediction software for use in dental offices.

Before joining CHR in 2002, Dr. Fellows served as a health economist at the Centers for Disease Control and Prevention (CDC)’s National Center for Chronic Disease Prevention and Health Promotion. He has been involved in tobacco control and other health services research since 1999, when he began working in the CDC’s Office on Smoking and Health. At the CDC, he led the domestic tobacco control economic evaluation program that included assessing the health and economic burden of tobacco. He also guided research on the impact of state excise taxes and state programs on cigarette consumption, smoking prevalence, and health outcomes.

As a CHR researcher, Dr. Fellows was the principal investigator on the Inpatient Technology-Supported Assisted Referral study linking hospitalized smokers at Kaiser Sunnyside, Oregon Health & Science University, and Legacy Emanuel hospitals to outpatient cessation services and medications. He was also principal investigator on a project estimating the return on investment of smoking cessation programs for health plans and employers, and numerous evaluations of the effectiveness of state tobacco control programs, including state tobacco quitlines. Currently, he is a co-investigator on a clinical trial evaluating the cost-effectiveness of smoking cessation clinical decision support, referral, and looped feedback reporting for community health center primary care teams.

Dr. Fellows holds a PhD in economics from the University of Utah.
