“Researchers continually generate new ways to improve health. But these advances don't make a difference unless people use them and systems implement them. My goal is to help people and communities use evidence to improve their lives.”

Leah Tuzzio, MPH

Research Associate, Kaiser Permanente Washington Health Research Institute


Leah Tuzzio, MPH’s research focuses on improving patient experience, reducing health care costs, and improving the health of populations. She is currently working with teams at KPWHRI’s MacColl Center for Health Care Innovation and the Center for Community Health and Evaluation on projects related to quality improvement in primary care, patient-centered care, community-based research, and translating evidence into practice.

One of her main projects is Healthy Hearts Northwest, an Agency for Healthcare Research and Quality-funded project to implement and evaluate quality improvement approaches in primary care. In addition, she is working with the National Institutes of Health (NIH) Collaboratory’s Health Care Systems Interactions core to report on lessons learned from implementing pragmatic trials.

Leah’s other projects include writing manuscripts from the Robert Wood Johnson Foundation-funded Learning from Effective Ambulatory Practices (LEAP) project, studying the primary care workforce and the role of lay health workers, providing technical assistance to the Patient-Centered Outcomes Research Institute’s first Evidence-to-Action Network focused on asthma research, and studying the use and adaptation of the Decision-to-Implement toolkit funded by the University of Washington’s Institute of Translational Health Sciences.

Leah has co-led Kaiser Permanente Washington's patient-centered care interest group since 2012, and she is a member of the Health Care Research Systems Network (HCSRN) Patient Engagement in Research Workgroup. She earned a Master of Public Health (MPH) at the Emory University Rollins School of Public Health in the Behavioral Sciences and Health Education program. Her master’s thesis was about the quality of life of people with dementia and their caregiver’s burden. While at Emory she helped disseminate the Center for Disease Control and Prevention’s Healthy Days quality of life measure across the United States and edited consumer books at the American Cancer Society’s national office.
