Carlos Castañeda-Orjuela presented a project on the use of cost-effectiveness analysis (CEA) for pneumococcal vaccines (PV) in Latin American countries at a CHDS research seminar. Low- and middle-income countries, including those in Latin America, face a limited health budget and must make difficult decisions about what health interventions they should fund, and CEA presents a potentially useful and objective way to make those decisions. Castañeda-Orjuela argued, though, that there has been little research on how countries in Latin America actually use CEA, and how the predictions from CEA in these countries compare to actual policy outcomes. To fill this gap, Castañeda-Orjuela presented a case study of the use of CEA for PV in Columbia, showing the results of a CEA for the different variants of PV and discussing how those results could be used to help make policy decisions.
While at CHDS, Castañeda-Orjuela collaborated with Stephen Resch and other faculty and staff. He produced educational materials for the EPIC3 project related to his research in decision science and immunization, and created content for the EPIC3 website. He also worked with Resch to build upon his dissertation work about the cost-effectiveness of Pneumococcal vaccination policies in Colombia.
