The Hidden Health Literacy Crisis That Begins Before You Reach the ER
In a quiet living room, a 63-year-old man sat slumped forward in his recliner, struggling to pull air into his lungs. His wife had called 911, telling the dispatcher he had a cold. She used the same word when the ambulance crew arrived: a cold. She was not lying, but she was missing the bigger picture. She had been watching her husband slowly get sicker for four days, yet she did not have the words to describe what she was really seeing. His blood pressure was a staggering 198/110, and his oxygen saturation had dropped to 84% on room air. These numbers signaled a medical crisis far beyond a simple cold, but no one on the other end of the phone could have known that from her description.
The Struggle to Share the Full Story
The emergency medical services (EMS) team spent 10 precious minutes trying to piece together his medication list. He was supposed to be taking seven different drugs. His wife could identify the bottles by color. She knew one pill was “for his heart” and another was “for the water his body likes to hold onto.” But she could not provide the medication names, the exact doses, or the conditions they treated. The bottles were stored in a bag somewhere in the house, and the crew found only three of them before they had to leave for the hospital.
The patient care report that arrived at the emergency department described a general illness in a man with a history of cardiac disease, high blood pressure, and an unknown medication plan. It was accurate as far as it went. Yet as a clinical document, it was shaped almost entirely by what his wife had been able to communicate in a language she had never been taught — a language of chief complaints, symptom timelines, and drug names that many of us take for granted.
Health Literacy: A Widespread Challenge
You may have seen patients like this man before. What you may not realize is just how common his situation is. Research shows that around 36% of adults in the United States have only basic or even below basic health literacy. Health literacy is the ability to find, understand, and use health information to make appropriate decisions. When that skill is limited, the effects ripple through every stage of medical care.
People with low health literacy tend to reach the emergency department later in the course of an illness, often with more advanced disease. They have higher rates of medication non-adherence and visit the emergency room more frequently for conditions that could have been managed earlier if they had recognized the warning signs. Hospitals have made significant progress in addressing this issue through better communication practices, discharge planning, and patient education. However, the prehospital world — the moments before a patient ever sets foot in the ER — has not kept pace with those reforms.
The 911 Call: A Hidden Test of Health Literacy
The prehospital journey starts not with the ambulance but with the decision to call for help. For someone with low health literacy, that choice is influenced by factors the emergency department never sees. Many people do not recognize the clinical importance of their symptoms. They may not know that jaw pain and left arm discomfort can signal a heart attack. They may not understand that progressive shortness of breath needs urgent medical evaluation, not watchful waiting. The grayish color of a loved one’s face at rest might be mistaken for simple tiredness rather than a sign of dangerously low oxygen. As a result, they delay, hoping things will improve, and sometimes the window for effective intervention closes before they pick up the phone.
When they finally call 911, the interaction itself becomes a complex health literacy task. The Medical Priority Dispatch System, which many emergency call centers use, asks callers to describe symptoms in medically recognizable terms, list medications by name and dosage, and follow multi-step instructions while under intense emotional pressure. If a caller cannot meet these demands, the dispatcher must make decisions based on incomplete information. The response priority, the type of crew sent, and the pre-arrival instructions all depend on what could be communicated in those first few minutes. A 2023 study published in JAMA Network Open confirmed that EMS providers see ineffective communication as a major barrier to delivering high-quality prehospital care, especially for patients with limited English skills, and the problem has not been systematically fixed at the protocol level.
On Scene: The Gaps Keep Growing
Once EMS crews arrive, the challenges multiply. The patient’s history — when symptoms started, how long they lasted, how severe they felt, and what medications they take — forms the foundation of every prehospital assessment. When health literacy limits that history, the clinical picture is built on shaky ground. Crew members do the best they can with the information available. The report they create reflects what was communicated, not necessarily what is medically true. The emergency physician who receives both the patient and that report inherits a gap they may never know exists.
Imagine being a doctor trying to treat a patient whose medication list is a guess based on bottle colors, whose symptom timeline is vague, and whose wife’s worry is the only clue that something serious could be unfolding. This is not a rare scenario; it is a predictable outcome of a system that has not been designed with the health literacy of the general population in mind.
The Unexpected Bill and Its Consequences
The health literacy burden does not disappear after the patient leaves the hospital. Ground ambulance services, unlike many other medical services, are explicitly excluded from the consumer protections of the No Surprises Act. About 51% of emergency ground ambulance rides are provided by out-of-network services, leaving millions of people vulnerable to unexpected bills. For someone with low health literacy, the billing document that arrives weeks later can feel like an incomprehensible puzzle written in the language of insurance companies. Even people with strong health literacy find these documents difficult to understand.
Evidence suggests that patients who receive surprise bills they cannot manage or make sense of are less likely to call for emergency help in the future. In this way, the health literacy failure that complicated the first 911 call now influences the decision about whether to make the next one. A person who cannot afford or understand an ambulance bill might hesitate the next time they feel chest pain or notice a loved one’s breathing change. That hesitation can be dangerous, even deadly.
What Experts Say About This Growing Concern
Health literacy experts have long pointed out that communication barriers in healthcare are not the patient’s fault. They are a system design problem. The American Medical Association and other organizations encourage healthcare providers to use plain language, the teach-back method (where a patient repeats information in their own words), and universal precautions that assume everyone may have difficulty understanding medical information. Emergency physicians often see the consequences of low health literacy in the form of delayed presentations and incomplete histories. They recognize that much of the damage happens before the patient ever reaches their door.
While hospitals have made strides in simplifying discharge instructions and offering interpreter services, the prehospital setting remains an area in need of major reform. There are no validated tools that EMS crews can use in the field to quickly assess a caller’s or patient’s health literacy. Dispatch protocols have not been adjusted to accommodate callers who cannot name symptoms in medical terms or list their medications by heart. Advocates are calling for change, including updated dispatch training, federal legislation to protect patients from surprise ambulance bills, and a deeper integration of health literacy awareness into the entire continuum of emergency care.
