Welcome to the Program on Medicines and Public Health within the Titus Family Department of Clinical Pharmacy at the University of Southern California. Our program focuses on the development and expansion of several research initiatives focusing on access to medications, drug utilization and pharmaceutical policy.

We conduct innovative drug utilization and pharmacoepidemiology research to better understand the underlying mechanisms responsible for the use, underuse, and unsafe use of medications, how these patterns may influence health outcomes and health disparities, and what can be done from a community and policy perspective to address these growing public health problems. 

Our mission is to improve equitable access and safe use of essential medicines in the U.S. and globally. The Program will develop and lead interdisciplinary research efforts focusing on drug utilization, access to medicines, and pharmaceutical policy to better understand why medications are used, or not used, and how they can and should be used in the population to promote equity, longevity, and good health.

Our goal is to improve our understanding of the role of medicines in public health and health equity and to promote public accountability to better ensure access to, and safe use of, medications at the national, state, and local levels. In an effort to achieve these goals, we often incorporate the health and human rights concept of ‘essential medicines’ in our research and programming.  

 

 

Recent Insights:

Jenny Guadamuz, Dima Qato, and their coauthors (2021) found that as of 2020, pharmacies in Black and Latino neighborhoods were more likely to close and less likely to offer immunizations, 24-hour, and drive-through services than pharmacies in other neighborhoods. Read the publication in the Journal of the American Pharmacists Association here.

In these visualizations, Guadamuz and co-authors (2021) explore trends and disparities in access to pharmacies across Los Angeles, Chicago, and Houston communities based on their racial or ethnic composition from 2015 to 2020. Guadamuz et al. hypothesized that disparities in the availability and access to pharmacies would be associated with racial or ethnic segregation, with fewer pharmacies being located in segregated minority communities.
