Disparities in healthcare-seeking behaviors and associated costs between Venezuelan migrants and Colombians residing in Colombia.

Abstract

Background: Colombia, which hosts over 3 million of the Venezuelan diaspora, is lauded for its progressive approach to social integration, including providing migrants access to its universal health coverage system. However, barriers to healthcare persist for both migrant and host populations, with poorly understood disparities in healthcare-seeking behaviors and associated costs. This is the first study to link healthcare-seeking behaviors with costs for Venezuelan migrants in Colombia, encompassing costs of missing work or usual activities due to healthcare events.

Methods: We use self-reported survey data from Venezuelan migrants and Colombians living in Colombia (September-November 2020) to compare healthcare-seeking behaviors and cost variables by nationality using two-sampled t-tests or Chi-square tests (X²). The International Classification of Diseases was used to compare reported household illnesses for both populations. Average health service direct costs were estimated using the Colombian Government's Suficiencia database and self-reported out-of-pocket (OOP) payments for laboratory and pharmacy services. Indirect costs were calculated by multiplying self-reported days of missed work or usual activities with estimated income levels, derived by matching characteristics using the Gran Enquesta Integrada de Hogares database. We calculate economic burdens for both populations, combining self-reported healthcare-seeking behaviors and estimated healthcare service unit costs across six healthcare-seeking behavior categories.

Results: Despite similar disease profiles, Venezuelan migrants are 21.3% more likely to forego formal care than Colombians, with 746.3% more Venezuelans reporting lack of health insurance as their primary reason. Venezuelan women and uninsured report the greatest difficulties in accessing health services, with accessing medications becoming more difficult for Venezuelan women during the COVID-19 pandemic. Colombians cost the health system more per treated illness event (US$40) than Venezuelans (US$26) in our sample, over a thirty-day period. Venezuelans incur higher costs for emergency department visits (123.5% more) and laboratory/ pharmacy OOP payments (24.7% more).

Conclusions: While Colombians and Venezuelans share similar disease burdens, significant differences exist in access, cost, and health-seeking behaviors. Increasing Venezuelan health insurance enrollment and tackling accessibility barriers are crucial for ensuring healthcare equity and effectively integrating the migrant population. Findings suggest that improving migrant access to primary healthcare would produce savings in Colombian healthcare expenditures.
