Instituto Costarricense de Equidad de Salud
Health equity,
grounded in
evidence.
We produce rigorous, community-centered research—and pair evidence with local investment—to improve care and strengthen the places people call home across Costa Rica and the Americas.
Our purpose
Field context
Images from Chinle, Arizona—where landscape, community, and access to care meet.Connecting place to health equity is central to how INCOESA understands underserved communities.
Better health systems begin by asking who has been left out—then designing the evidence, tools, and partnerships to bring them in.
Equity, diversity, and inclusion are foundational to our work. They shape the questions we ask, the communities we partner with, the investigators and artists we support, and how we share resources and opportunity.
Human dignity is indivisible. INCOESA stands firmly against antisemitism and against racism, xenophobia, anti-Palestinian hatred, anti-Muslim hatred, and religious discrimination in all forms.
Health equity also requires speaking clearly when civilian health and human rights are at stake. INCOESA calls for an immediate and durable end to the war in Gaza, protection of civilians and healthcare workers, and unhindered humanitarian access. INCOESA aligns with the September 2025 conclusion of the United Nations Independent International Commission of Inquiry that Israel has committed genocide in Gaza.

Healthy Places Initiative
Research helps us understand place.
Partnership helps us strengthen it.
INCOESA studies how geography and the built environment shape health, access, and belonging. We believe communities should not only be the subject of research—they should share directly in the investment that research inspires.
Our first creative-placemaking program will support community-led murals in Costa Rica and Tucson, Arizona, bringing residents, local artists, schools, clinics, and neighborhood organizations together to transform shared spaces.
Led locally
Residents and community partners help select the site, shape the story, and approve the final concept.
Artists are paid
Grant budgets prioritize fair compensation for local artists alongside materials, preparation, and maintenance.
Impact is documented
Each project will preserve its community story and examine participation, belonging, stewardship, and neighborhood pride.
Research
Questions that matter
where access is hardest.
Our research connects clinical care, technology, spatial analysis, and community knowledge to understand—and close—gaps in health access.
Research areas
Our portfolio is organized around four connected areas where geography, technology, clinical care, and community experience intersect.
Digital Health Equity
Examining who is represented in AI, mobile health, and telehealth research—and who is excluded from the benefits of clinical innovation.
Rural Emergency Care
Using health services research and geographic information systems to improve emergency care access in rural and resource-limited settings.
Point-of-Care Ultrasound
Studying equitable adoption of ultrasound and other clinical technologies within Costa Rica's national health system.
Indigenous Health
Supporting culturally grounded research and partnerships focused on Indigenous and hard-to-access communities.
Featured publication
PURA-ECHO: Mapping equitable ultrasound access across Costa Rica.
INCOESA’s inaugural publication uses ArcGIS and sixteen years of national ultrasound utilization data to show how diagnostic capacity expanded across Costa Rica’s CCSS network.
The study found a 3.2-fold increase in rural ultrasound exam volume, while distance from the national referral center did not predict adoption—highlighting the equity-promoting strength of Costa Rica’s EBAIS geographic empanelment model.

Understanding the NIH Diversity Supplement and the emergency medicine research pipeline.
This Annals of Emergency Medicine research letter examined NIH ExPORTER data from 2002 to 2023 to understand how the NIH Diversity Supplement supported clinician-scientist development across medical specialties.
Emergency medicine ranked strongly by participation rate: 21 diversity supplements were awarded across 14 parent grants at 7 academic programs, with 17 of the 21 awarded between 2020 and 2023.

Embedding healthcare disparities education into existing medical school lectures.
This BMC Medical Education study evaluated a resource-conserving curriculum that used “teachable moments” to integrate guideline-based health disparities content into existing first-year medical school lectures without adding lecture time.
Across 43 lectures, 26 were enhanced with 213 disparities topics. Students who used the materials more frequently demonstrated greater post-course knowledge and higher confidence addressing healthcare disparities in clinical settings.
