Overview
Darren Toh, ScD is Professor in the Department of Population Medicine at Harvard Medical School and Harvard Pilgrim Health Care Institute. He is a pharmacoepidemiologist with an interest in the comparative safety and effectiveness research of medical products. His research focuses on 1) assessing the risks and benefits of medical products using electronic data collected as part of routine healthcare delivery, and 2) developing and applying privacy-protecting analytic methods to conduct multi-center studies in distributed data networks.

Darren is Chief Scientist at the Operations Center of the FDA-funded Sentinel System, a congressionally mandated national medical product safety surveillance system. He is Principal Investigator of projects funded by the National Institutes of Health (U01EB023683), the Agency for Healthcare Research and Quality (R01HS026214), the Patient-Centered Outcomes Research Institute (ME-1403-11305), and the Food and Drug Administration. Darren received his doctoral degree in Epidemiology from the Harvard School of Public Health.

Embedded pragmatic clinical trials (ePCTs) are an appealing and efficient approach to compare the real-world effectiveness and safety of different pharmacotherapies, but the success of such ePCTs largely hinges on the ability to reliably recruit, randomize, and retain patients. Our team studies the use of approved (on-label) and unapproved (off-label) medications for insomnia, and we are conducting a study to better understand barriers and facilitators to physicians and patients participating in ePCTs where the pharmacologic treatment for insomnia is randomized. This qualitative project will involve conducting and analyzing data from surveys, semi-structured interviews, and focus groups with physicians and patients with insomnia. Interested students will have the opportunity to participate in the data collection and analysis process, preferably as an HMS Scholarly Project. Prior experience in qualitative research is ideal, though not required. The findings from this project will help inform the design of future ePCTs involving insomnia pharmacotherapies to ensure that the design of such trials is sensitive to and adequately addresses the concerns of patients and physicians.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
