An Analysis of Healthcare Utilization Amongst Undocumented Patients, 2014-2018

Abstract: The deportation of undocumented immigrants has increased since the 2016 presidential election. The increased rate of immigration enforcement might discourage undocumented patients from receiving healthcare. My hypothesis is that there has been a decrease in primary care utilization and an increase in inpatient utilization amongst undocumented immigrants since the 2016 election. In this study, I will analyze primary care and inpatient utilization amongst a pool of undocumented patients and Medicaid controls in an mid-Atlantic health system between 2014-2018 using difference-in-difference analysis. The primary aim of the analysis would be to determine changes in primary care visits November 9, 2016 and May 31, 2018, with January 1, 2014-November 8, 2016 serving as a reference period. A secondary aim will be to determine changes in inpatient utilization comparing the same two periods. I will be conducting this research with Sarah Polk, MD ScM MHS, a nationally respected expert in Latino health disparities. I have gathered all the necessary approvals for human subjects research from the health system of interest and have begun to extract data for internal medicine and pediatrics encounters. Analysis and data management will be principally done by myself with the assistance of a statistician who has reviewed hypotheses and study design. The purpose for this proposal will be to gain funding to purchase further biostatistics support and obtain obstetrics and gynecologic encounter data.
