Dr. Molly Moore Jeffery is a health services researcher and health economist. Her research centers on the use of administrative data to understand the choices patients and physicians make in selecting the appropriate resource inputs and locations of care and how they affect patient and system outcomes. She develops research methods to use administrative data--collected for purposes other than research--to develop insight and evidence to improve clinical practice and patient outcomes. A current focus of her research is using claims and electronic health record data to study the use of opioids in settings including emergency departments, post-surgery, and primary care. She is currently leading an FDA-sponsored multi-site study prospectively enrolling 1500 people with acute pain receiving an opioid prescription to understand and document patient-reported outcomes including progression to chronic pain, impact on continued opioid use, use of non-pharmaceutical treatments, and multiple domains of health and social functioning.
