C. Holly Andrilla
Research Scientist/Engineer - Senior


Holly Andrilla is a senior research scientist and biostatistician at the WWAMI Rural Health Research Center in Seattle, Washington. She is a national expert on the workforce trained to provide medication treatment of opioid use disorder. She has conducted studies exploring the geographic and specialty distribution and prescribing practices of US physicians, nurse practitioners and physician assistants with a Drug Enforcement Administration (DEA) waiver to treat opioid use disorder. In June 2016 she participated in the United Nations Office on Drugs and Crimes meeting to develop a model for drug prevention and treatment in rural settings. Ms. Andrilla led a national study to quantify the availability of medication treatment in rural areas of the United States. She developed a model to project the contribution of nurse practitioners and physician assistants to providing medication treatment in rural areas when the Comprehensive Addiction and Recovery Act extended the ability to obtain a DEA waiver to them. She is expert in managing large datasets; designing, performing and interpreting complex statistical analyses; and conducting survey research. Ms. Andrilla has had major analytic roles in workforce studies of physicians, physician assistants, dentists, dental hygienists, registered nurses, advanced practice nurses, and other groups. She has directed surveys of health care professionals and facilities, including a national survey of federally-funded health centers, and a national survey of family practice residencies.

Current Projects

Ms. Andrilla is currently leading a study looking at the trends in the Geographic Distribution of the Workforce with a DEA Waiver to Prescribe Buprenorphine. She also serves as a co-investigator on several projects being conducted by the Collaborative for Rural Primary care Research, Education, and Practice (Rural PREP).
