Six Months of Remote Patient Monitoring Is Associated with Blood Pressure Reduction in Hypertensive Patients: An...

Remote physiological monitoring (RPM) is a form of telehealth that measures vital signs at home and automatically reports the results to providers, thereby possibly improving chronic disease management. Medicare payment for RPM began in 2019. Two potential obstacles to RPM growth are the paucity of published clinical outcomes data and the Medicare requirement that monitoring be done at least 16 days per month to bill for the service. To help address these issues, we report the following uncontrolled observational study. A total of 1,102 consecutive patients enrolled in RPM were divided into four groups based on initial average mean arterial pressure (MAP) and into six groups based on the number of days per month MAP was measured. We report changes in MAP after 6 months of RPM as a function of initial MAP, and number of days per month MAP was monitored. After 6 months of RPM, average MAP dropped from 97 to 93 (p < 0.01). This drop was greatest in the 50% of patients initially hypertensive. These patients saw average MAP reductions from 106 to 97 (p < 0.001) and became normotensive. Although MAP reduction was greatest the more frequently patients measured, significant reduction occurred in the hypertensive patients whether they measured more or less than 16 days per month (p < 0.001). No minimum threshold of measurements was found that predicted failure of RPM to lower MAP. RPM is associated with clinically and statistically significant reductions in average MAP in patients who were initially hypertensive. This benefit occurred irrespective of the number of days per month patients measured MAP.
