Summary
Primary care physicians' intention to refer patients to digital health programs, like remote blood pressure monitoring, is significantly influenced by their knowledge of the program. Educating physicians is key to increasing patient access to these beneficial digital health tools.
Area of Science:
- Digital Health
- Primary Care Medicine
- Health Informatics
Background:
- Referral rates to digital health programs by primary care physicians (PCPs) vary significantly.
- Understanding factors influencing PCP referrals to digital health, such as remote blood pressure monitoring (RBPM), is crucial.
Purpose of the Study:
- To examine how PCPs' knowledge of a digital RBPM program and referral data (self vs. peer) impact their intention to refer patients.
- To assess the relationship between PCPs' understanding of digital health tools and their likelihood of patient referral.
Main Methods:
- A mixed-methods approach combining electronic health record data and surveys.
- PCPs were surveyed on program knowledge and referral intent after being randomized to receive self-referral rates or self-and-peer referral rates.
- Clinical vignettes were used to assess referral likelihood, followed by regression and thematic analyses.
Main Results:
- PCPs' intention to refer was significantly associated with their knowledge of the digital health program (coefficient 0.46, P<.001).
- Intent to refer a vignette patient strongly predicted intent to refer future patients (coefficient 0.62, P<.001).
- Providing peer referral data did not significantly alter PCPs' intent to refer compared to providing only self-referral data.
Conclusions:
- A PCP's intention to refer to a digital health program can be predicted by their vignette-based referral intent, which is strongly linked to program knowledge.
- Enhanced physician education and engagement are recommended to increase the adoption of digital health programs for patient benefit.

576
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

01:28Special considerations while measuring blood pressure
694
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

1.9K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
