Daniel Hartung is an associate professor of pharmacy practice in the College of Pharmacy at Oregon State University / Oregon Health & Science University. Hartung conducts pharmaceutical health services research and pharmacoepidemiology with an emphasis on substance use disorders and prescription drug policy. Hartung’s principal focus is determining how state and federal policies to reduce risks associated with prescription opioid misuse affect prescription drug utilization and health outcomes. To support his work, Hartung has secured over $4.8 million in grants and contracts (since 2014) from federal agencies such as AHRQ, CDC, and NIH (NIDA) and has published 60 peer-reviewed manuscripts, many as first author in high impact journals such as JAMA, Health Affairs, and Annals of Internal Medicine. Although much of his work involves state Medicaid data, Hartung also has experience working with PDMP, vital statistics, TEDS, and Medicare data. Within Oregon, Hartung has lead studies to link state administrative data to conduct SUDs policy and epidemiologic investigations. His current effort involves linking Oregon Department of Corrections data to other state data sources to characterize trends treatment patterns, overdose, and other outcomes for criminally involved individuals.
