The Challenge of Communicating Medical Numbers Effectively
Navigating health information can be daunting for many, and the way numerical data is presented plays a crucial role in understanding risks and making informed decisions. Recent research underscores the importance of clear and consistent communication of medical statistics, particularly when discussing probabilities and potential outcomes. While healthcare professionals generally agree on the need to use numbers when conveying medical risks, the *how* remains a complex issue. Effective communication isn’t simply about presenting the data; it’s about ensuring patients truly grasp its meaning and can apply it to their own circumstances. This is especially critical in an era where individuals are increasingly expected to participate actively in their healthcare journey.
A study published in Med Decision Making on June 24, 2025, by Benda, Zikmund-Fisher, and Ancker, details guidelines for reporting research on the communication of health-related numbers, known as the ReCoN guidelines. The research highlights the need for standardized approaches to presenting numerical information to improve patient comprehension. The authors emphasize the value of using consistent, rounded denominators – for example, stating a risk as “3 in 1000” rather than a more precise but potentially confusing fraction. This approach aims to simplify the information without sacrificing accuracy.
Why Numbers Matter in Healthcare Communication
The ability to understand medical statistics is fundamental to informed consent and shared decision-making. Patients need to be able to weigh the potential benefits of a treatment against its risks, and this requires a clear understanding of the numbers involved. However, research consistently demonstrates that people struggle with numerical concepts, particularly when presented in complex formats. This struggle can lead to misinterpretations, anxiety, and suboptimal healthcare choices. For example, a patient might overestimate the risk of a rare side effect if it’s presented as a percentage without context, or underestimate the benefit of a treatment if the absolute risk reduction is small.
Brian J. Zikmund-Fisher, of the University of Michigan School of Public Health, has been a leading voice in advocating for improved communication of medical numbers. His work, as detailed in a JAMA Insights article published on September 24, 2025, provides evidence-based recommendations for communicating numerical information to patients. The core principle is to present information in a way that is both accurate and accessible, avoiding jargon and complex statistical terms. This includes using visual aids, such as bar graphs or pictograms, to illustrate probabilities and risks.
The Pitfalls of Poor Numerical Communication
Poorly communicated medical numbers can have serious consequences. Misunderstandings about risk can lead patients to forgo beneficial treatments or to demand unnecessary interventions. In the context of public health, inaccurate or misleading statistics can fuel vaccine hesitancy or undermine efforts to control infectious diseases. The way numbers are framed can significantly influence perceptions. For instance, stating that a treatment has a “90% survival rate” is likely to be perceived more favorably than stating that it has a “10% mortality rate,” even though the two statements convey the same information. This phenomenon, known as framing bias, highlights the importance of carefully considering the language used to present medical statistics.
Best Practices for Presenting Medical Data
Several strategies can improve the communication of medical numbers. One key recommendation is to use absolute risk reductions rather than relative risk reductions. Absolute risk reduction represents the actual difference in risk between two groups, while relative risk reduction expresses the reduction in risk as a proportion of the baseline risk. For example, if a drug reduces the risk of a heart attack from 2% to 1%, the absolute risk reduction is 1%, while the relative risk reduction is 50%. The latter figure can be misleadingly large, suggesting a much greater benefit than is actually the case.
Another important principle is to use consistent denominators. As the ReCoN guidelines suggest, expressing risks as “X in 1000” or “X in 100” can make it easier for patients to grasp the magnitude of the risk. Avoid using percentages when the denominator is not readily apparent, as this can make it difficult to compare risks across different conditions or treatments. It’s crucial to provide context and explain what the numbers mean in practical terms. For example, instead of simply stating that a treatment reduces the risk of a stroke by 20%, explain that this means that 20 fewer people out of 100 will experience a stroke.
Visual Aids and Patient-Centered Communication
Visual aids can be powerful tools for communicating medical numbers. Bar graphs, pie charts, and pictograms can help patients visualize probabilities and risks in a more intuitive way. However, it’s important to use visual aids carefully, ensuring that they are clear, accurate, and not misleading. Avoid using three-dimensional charts or complex color schemes, as these can distort the data and make it harder to interpret.
effective communication of medical numbers requires a patient-centered approach. Healthcare professionals should seize the time to understand their patients’ numeracy skills and tailor their explanations accordingly. They should similarly encourage patients to ask questions and express any concerns they may have. Using plain language, avoiding jargon, and providing clear and concise explanations are essential for ensuring that patients understand the information being presented. The AMA Ed Hub provides resources for clinicians on how to improve their communication skills in this area.
The Role of Technology in Improving Communication
Technology offers promising avenues for enhancing the communication of medical numbers. Interactive decision aids, for example, can allow patients to explore different treatment options and see the potential benefits and risks visualized in a personalized way. Mobile apps can provide patients with access to educational materials and tools for tracking their health data. Artificial intelligence (AI) can be used to generate personalized explanations of medical statistics, tailored to each patient’s individual needs and understanding. However, it’s important to ensure that these technologies are evidence-based and designed with patient usability in mind.
the increasing availability of patient portals and electronic health records (EHRs) presents both opportunities and challenges. While these platforms can provide patients with access to their medical information, the way this information is presented can significantly impact comprehension. EHRs should be designed to display numerical data in a clear and accessible format, avoiding complex tables and jargon. They should also provide patients with tools for interpreting the data and understanding its implications.
Future Directions and Ongoing Research
Research on the communication of health-related numbers is ongoing. Future studies will likely focus on developing and evaluating new communication strategies, exploring the role of technology, and identifying the factors that influence patient comprehension. Particular attention will be paid to addressing health literacy disparities and ensuring that all patients have access to clear and accurate information. The ReCoN guidelines, developed by Benda, Zikmund-Fisher, and Ancker, represent a significant step forward in this effort, providing a framework for researchers and clinicians to improve the way medical numbers are communicated.
The ongoing work to refine these guidelines and implement them in clinical practice is crucial for empowering patients to make informed decisions about their health. As healthcare becomes increasingly complex, the ability to understand and interpret medical statistics will become even more important. By prioritizing clear and accessible communication, One can help ensure that all patients have the information they need to navigate the healthcare system effectively.
The next update to the ReCoN guidelines is scheduled for review in early 2027, as reported by the research team.
