A pharmaceutical company spends years developing a breakthrough treatment. A HUB service builds a robust patient support program around it. A specialty pharmacy stands ready to dispense. And then a patient, confused by a re-enrollment form they didn’t know existed, quietly abandons their medication.
No one intended this outcome. The system worked exactly as designed. And yet the patient fell through a gap that no one thought to close.
That gap is health literacy.
What Health Literacy Actually Means
Health literacy is both personal and organizational. On the individual side it is a patient’s ability to find, understand, and use health information to make informed decisions. On the organizational side it is the capacity of health systems and programs to communicate in ways that actually enable patients to do so.
Only 12% of U.S. adults have proficient health literacy according to the CDC. The vast majority of patients navigating prior authorization appeals, copay assistance enrollment, and specialty pharmacy processes are doing so with limited ability to parse the language those systems use.
This is not a patient failure. It is a communications failure.
Where Access Programs Break Down
Consider what a patient must actually do to access a copay assistance program. They must identify that the program exists, determine their eligibility based on specific insurance criteria, complete financial forms with precise documentation, and critically—understand that many programs require annual re-enrollment. Miss that last step and coverage lapses without warning.
Or consider a prior authorization appeal. Patients must understand terms like “formulary exception,” “medical necessity,” and “coinsurance.” They must gather specific clinical documentation within strict deadlines ranging from 30 to 180 days. They must navigate a process designed by and for administrators—not patients.
When materials assume literacy, medical knowledge, or technological proficiency that most patients don’t have the consequences are measurable. 38% of patients walk away without their medication when facing unexpected costs or administrative complexity. Low health literacy correlates directly with higher hospitalization rates, higher emergency department visits, and thousands of dollars in additional annual healthcare costs per patient.
The program didn’t fail. The communication did.
What Better Looks Like
The solutions are neither expensive nor complicated. Plain language materials written at a fifth grade level. Visuals that replace or support dense text. The teach-back method — asking patients to explain the process back in their own words — which consistently improves comprehension and adherence. Human patient navigators for the moments when a form or a phone call requires real support.
None of these are radical interventions. They are communications decisions.
The best access program in the world cannot help a patient who cannot understand it. Health literacy is not a nice-to-have consideration in program design. It is the foundation everything else is built on.
