Macarius Donneyong, PhD, MPH
Nearly three out of every five adults in the United States consume prescribed medications. Dr. Donneyong’s research focuses on the safety and effectiveness of medications and medical devices. Specifically, he applies quantitative methods from epidemiology, pharmacoepidemiology, biostatistics and data analytics to analyze large healthcare databases such as health insurance claims and other linked databases which capture prescribed medication use and outcomes on their safety and effectiveness. Currently, Donneyong focuses on:
- Drug-drug interactions: The simultaneous use of multiple medications is growing increasingly common. He investigates whether it is safe to simultaneously use certain medications or not.
- The role of the social determinants of health factors on the effectiveness of prescribed medications: He is interested in how the conditions in which people are born, grow, live, work and age influence the safety and effectiveness of prescribed medication use in the community settings.
- Medication outcomes among racial/ethnic minorities: Through population-based observational studies, he tries to measure differences in the utilization, safety and effectiveness of prescribed medications between racial groups, as racial/ethnic minority groups tend to be under-represented in clinical trials of drugs.
Marcia Worley, PhD
Prescription medication use in the United States is widespread and many patients have problems managing their medication regimens. Medication management and adherence can be especially difficult for older patients and patients with chronic illnesses. This leads to poor health outcomes, as well as increased costs for patients and the healthcare system. Dr. Worley’s research focuses on investigating the medication use process from the patient’s perspective, including patient reported outcomes. She has a specific interest in patient medication adherence and conducts research through application of health behavior and cognitive psychology theories, and relationship marketing models; using qualitative, quantitative and survey research methodologies. Dr. Worley has extensive experience developing and validating measurement tools for her research. The goal of her research program is to develop tools, interventions, and strategies that pharmacists can use to engage patients in the medication use process, thereby optimizing medication use behaviors and outcomes.
