Division of Health Services Research & Implementation Science



Dr. Erin Hahn is a health services researcher and implementation scientist. Her primary research interests are quality of care in oncology and the implementation of evidence-informed practices. She is particularly interested in the post-treatment care of cancer survivors. Dr. Hahn’s work combines qualitative and quantitative methods. Her research explores variations in care delivery, views and opinions of patients and clinicians, and the association of multi-level factors with health care utilization and outcomes. She is also an associate professor in the Department of Health Systems Science of the Kaiser Permanente Bernard J. Tyson School of Medicine.

Dr. Hahn is leading several large studies of cancer prevention and cancer care delivery, including a trial evaluating a new model of care for cancer survivors, an implementation-focused study on increasing HPV vaccination in children, and a multi-site study assessing the care experiences of adolescents and young adults with cancer. Dr. Hahn recently completed an implementation trial of systematic distress screening in oncology and is overseeing the regional implementation of the screening program.
