Department of Epidemiology and Biostatistics Seminar Series

2:30 PM-3:30 PM
Ernesto Ulloa-Pérez, PhD, Center for Improving Care Delivery for the Aging Postdoctoral Fellow, Leonard Davis Institute of Health Economics, University of Pennsylvania, will present "Evaluating payment programs via statistical methods for staggered adoption
interventions."
Population-level interventions often face practical constraints that
require a non-randomized staggered implementation. In this talk, I will provide
a motivating example of a payment intervention program that was implemented in
a staggered fashion by a health provider. Leveraging patient clinical registry
and medical claims data, I will illustrate how one could evaluate the program's
impact on quality-of-care indicators. To our advantage, significant progress
has been made recently in the development of statistical methods designed for
non-randomized staggered interventions. I will highlight how these methods can
be applied to estimate the program's effects and discuss how they target
different estimands. Additionally, I will address real-world challenges encountered
in our example, such as clinic-level heterogeneity and treatment switching.
Finally, I will present a comparative assessment of these methods through
simulation studies, showcasing their relative strengths and limitations in
different scenarios.
Dr. Ernesto Ulloa-Pérez is a postdoctoral researcher at the University of
Pennsylvania and a CICADA Fellow at the Leonard Davis Institute of Health
Economics. He earned his PhD in Biostatistics from the University of
Washington, where he specialized in advancing causal inference methods. His
current work focuses on developing and applying statistical methods for
staggered adoption interventions, providing policymakers with insights to
improve care delivery and health outcomes. Dr. Ulloa-Pérez’s applied research
leverages electronic health record data to address critical questions in health
policy and clinical care. His projects include evaluating treatment utilization
patterns following FDA approvals, and assessing vaccine safety through
post-marketing studies.
