Project Access Tarrant County

At Project Access Tarrant County, we have always believed that the “access” in our name involves more than seeing a specialist—it also includes comprehension. A growing body of research confirms what community health organizations have long observed: Health literacy is directly tied to healthcare utilization, outcomes, and cost.
Health literacy, as defined by Healthy People 2030, is “the degree to which individuals have the ability to find, understand, and use information and services to inform health-related decisions and actions for themselves and others.”1 PATC is uniquely positioned to help our patients improve health literacy not just for their PATC service, but also for their future lifetime of healthcare.
A 2025 systematic review found that limited health literacy is consistently associated with higher healthcare costs, increased hospitalizations, and greater emergency department use—all areas PATC aims to reduce in Tarrant County.2 Literacy is not a secondary social factor; it is a healthcare variable. Health literacy influences how patients navigate outpatient, inpatient, emergency, and digital health systems (even more so in immigrant populations)—and PATC is changing how we approach this issue in our patient base.
Moving Beyond “High School or Not”
Historically, many healthcare systems—including safety-net organizations—have captured each patient’s education level in broad terms. Emerging research shows that education level alone does not reliably predict a patient’s ability to understand medical terminology, consent forms, referral instructions, or post-procedure care plans. Studies have demonstrated that even patient-facing surgical materials are frequently written above recommended reading levels.
A decade ago, the AMA and National Institute of Health recommended that medical materials be written at an eighth grade or below reading level,3 but today, most experts agree that material should be written at a sixth grade or below reading level.4
When written information assumes advanced comprehension, patients are placed at risk of misunderstanding critical instructions. Just last year, a PATC patient almost canceled her vital surgery because she mistakenly thought she was instructed to stop her diabetes medication for a full week leading up to her surgery. She had enough health literacy to question those instructions, but not enough confidence to question their accuracy.
To respond more intentionally, PATC is refining how we capture and evaluate education and health literacy across our patient population.
What We’re Changing
- Narrowing our educational ranges
Rather than broad categories, we now collect more targeted education data. This allows us to examine patterns in referral completion, adherence, and communication preferences. - Identifying whether education occurred inside or outside the United States
Educational systems vary widely across countries. A high school diploma earned abroad may reflect a different exposure to English-language healthcare terminology or system navigation. Recent national research examining health literacy by Hispanic ethnicity reinforces this nuance.5 - Implementing SAHL evaluations for each adult patient
PATC is incorporating the Short Assessment of Health Literacy (SAHL), a validated screening tool created in 2010 by Health Services Research that directly measures a patient’s ability to recognize and understand common medical terms.
Unlike education level, SAHL evaluates functional comprehension—an essential factor in specialty care navigation. The tool is curated in both English and Spanish, with other languages available.6
Why Literacy Directly Impacts Care
Health literacy affects:
- Medication adherence
- Chronic disease management
- Completion of specialty referrals
- Understanding of pre-procedure instructions
- Post-surgical recovery compliance
Systematic reviews across multiple countries show that lower health literacy is associated with delayed care, increased acute utilization, and poorer chronic disease management—even in universal healthcare systems, insurance coverage alone does not eliminate access barriers.7
For uninsured patients navigating specialty referrals—often involving multiple providers, consent forms, preparation instructions, and follow-up plans—comprehension is foundational. When literacy gaps are not identified, missed appointments may be labeled as “noncompliance.” In reality, they may reflect confusion, fear, or uncertainty.
Connecting Data to Our Broader Health Literacy Efforts
Importantly, PATC’s shift is not just about collecting more data. It strengthens and informs our broader health literacy initiatives, including:
- Simplifying written instructions
- Evaluating readability of patient-facing materials
- Reinforcing clear text-based communications (CareMessage)
- Informing topics for future Salud en Tus Manos curriculum
Literacy is not just a patient issue—it is a system design issue. By measuring literacy more intentionally, PATC can ensure that communication strategies match patient needs.
Access Requires Understanding
Healthcare systems are becoming increasingly complex and digital. Artificial intelligence tools, online portals, and automated communications can enhance access—but only if patients can understand and use them effectively.
Access to care is not complete when an appointment is scheduled. It is complete when a patient understands what that appointment means—and what to do next.
By refining how we measure education and incorporating validated literacy screening, PATC is strengthening the foundation of specialty care coordination—because access begins with understanding.
