Smoothed Blood Pressure Graphs Improve Clinical Decisions, Study Shows
Updated May 30, 2025
A University of Missouri study indicates that the type of graph used to display blood pressure data can considerably impact a doctor’s assessment. The research highlights the challenges in accurately evaluating blood pressure due to its natural variability.
Victoria Shaffer, a psychology professor and lead author, noted the phenomenon of “white coat hypertension,” where blood pressure readings are elevated in a clinical setting but normal at home. She estimated that a meaningful percentage of diagnosed high blood pressure might be controlled outside the doctor’s office.
The study involved showing 57 doctors blood pressure data of a hypothetical patient using two graph types: a raw graph displaying actual numbers with peaks and valleys, and a smoothed graph averaging out fluctuations. The doctors more accurately assessed patients’ health using the smoothed graph when blood pressure was under control but exhibited fluctuations.
Shaffer explained that raw data can be visually noisy,making it arduous to interpret. The smoothed graph offers a tool for doctors to quickly and accurately determine if blood pressure is under control.
This study serves as a foundation for ongoing research with Richelle Koopman, a professor in the School of Medicine, in collaboration with Vanderbilt University and Oregon Health & Science University. The team aims to integrate the smoothed graph technology into HIPAA-compliant electronic health records, potentially allowing patients to monitor their blood pressure at home.
This advancement could ease the burden on the health care system by reducing the need for in-person visits and minimizing false positives that lead to over-treatment.
“Ther are some people who are being over-treated with unnecessary blood pressure medication that can make them dizzy and lower their heart rate,” Shaffer said. “This is notably risky for older adults who are more at risk for falling. Hopefully, this work can help identify those who are being over-treated.”
Shaffer stated that thes findings align with the understanding that humans are visually drawn to extreme cases, perceiving them as threats. She emphasized that this bias affects both patients and providers.
With the rise of health informatics and wearable devices, smoothed graphs could be applied to interpret various health metrics, providing better context and facilitating timely action.
“We have access to all this data now like never before, but how do we make use of it in a meaningful way, so we are not constantly overwhelming people?” Shaffer said. “With better visualization tools, we can give people better context for their health details and help them take action when needed.”
What’s next
Future research will focus on integrating the smoothed graph technology into patient-accessible electronic health records and exploring its request to other health metrics tracked by wearable devices.
