Colorectal Cancer Screening Communication and Completion Among Black and Hispanic Primary Care Patients

Colorectal cancer is a leading cause of death in the United States, but it is also one of the most preventable. The key to prevention lies in screening, a set of tests that can find the disease early or stop it before it starts. Medical guidelines recommend that adults between the ages of 45 and 75 undergo these checks. However, the reality is that not everyone gets screened equally. Significant gaps exist in who receives these life-saving tests, with Black and Hispanic communities often facing higher rates of missed diagnoses and later-stage detection. These disparities are not just about biology; they are often driven by social barriers, such as the cost of care, lack of transportation, and the quality of the conversation between a patient and their doctor. When a doctor explains the importance of screening clearly and a patient feels heard and trusted, the likelihood of getting tested increases. Yet, we know very little about how these conversations specifically play out for Black and Hispanic patients, or how factors like a patient's ability to understand medical forms or their trust in the healthcare system influence their decision to follow through.

To uncover these hidden dynamics, researchers at the MedStar Health Research Institute conducted a study focused on Black and Hispanic patients who had recently visited primary care clinics in Washington, D.C., and Maryland. The team wanted to understand the full journey of colorectal cancer screening: from the moment a doctor brings it up, to the patient's decision to act, and finally, whether the test was actually completed. They reached out to nearly a thousand patients, eventually speaking with 204 individuals who agreed to answer a short survey about their recent medical experiences. The participants were asked about their age, education, insurance, and how comfortable they felt reading hospital materials. Crucially, they were also asked to rate how well their doctors communicated with them about colon health and how much they trusted the healthcare system. The goal was to see which of these factors made the difference between a patient who got screened and one who did not.

The results painted a clear picture of where the system is succeeding and where it is failing. Among the patients surveyed, about 35 percent were up to date with their screening, while another 15 percent had been screened in the past but were now overdue. A significant portion, 36 percent, reported that their doctor had recommended the test but they had not yet completed it. Perhaps most concerning was that 14 percent of the patients said their doctor had never discussed colorectal cancer screening with them at all. When the researchers looked deeper into the data, they found that age played a major role; older patients were more likely to have completed screening than younger ones. However, race and ethnicity told a more complex story. While Black patients generally reported positive experiences with their doctors, Hispanic patients faced distinct hurdles. A much larger share of Hispanic patients said they had never discussed screening with their provider compared to their Black counterparts. Furthermore, Hispanic patients reported lower levels of comfort when reading medical documents and lower scores on measures of patient-centered communication, which refers to how well a doctor listens, explains, and involves the patient in their care.

The study also examined the role of trust and health literacy. Health literacy, in this context, is simply how easy it is for a person to understand and use health information. The researchers found that patients who felt confident reading hospital materials were more likely to have completed screening. Interestingly, while the study measured how much patients distrusted the healthcare system, this factor did not show a direct statistical link to whether they got screened in this specific group. Instead, the strongest predictors for completing a screening were being older, being Black rather than Hispanic, and having the practical ability to read and understand medical instructions without help. The data suggests that for Hispanic patients, language and communication barriers may be acting as a wall, preventing them from receiving or acting on recommendations that are already being offered to others.

These findings suggest that the path to closing the gap in colorectal cancer screening is not one-size-fits-all. The researchers conclude that to improve screening rates, especially among younger, Hispanic, and less health-literate populations, outreach efforts must be tailored to their specific needs. This could mean providing patient navigators who speak Spanish to help guide patients through the process, or ensuring that doctors take extra time to explain screening options in plain language. The study highlights that while the medical recommendation is the first step, the quality of the communication and the support a patient receives afterward are what ultimately determine whether a life-saving test gets done. By focusing on these modifiable factors, healthcare providers can move closer to a future where every patient, regardless of their background, has an equal chance of staying healthy.
