s e255156 mmHg (SD 20), DPB 100 mmHg (SD 11). Acceptability: 8/12 participants responded via SMS with at least one BP measurement in the SMS arm. Two participants were lost to follow up in each arm. Mean SUS was 81.6 (scale of 0 to 100, > 68 is considered above average). Reduction in SBP at 12 weeks in the SMS group and control group was 15 mmHg and 13 mmHg respectively (p = 0.58).
Conclusion:Recruiting and retaining LSES participants with uncontrolled HTN for a larger trial of telehealth with SMS and HBPM is feasible and well accepted. Similar BP reductions were achieved in both arms. Utilizing the SMS and HBPM shows promise in reducing BP in the LSES population. A larger efficacy trial is needed to determine best practice and reduce cardiovascular health disparities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
