Does a physician-supervised web-based mHealth app reduce blood pressure in patients at a hypertension clinic?
The use of a physician-supervised mHealth app in clinical practice is associated with modest but significant reductions in blood pressure, particularly in patients with higher baseline severity.
Mean Difference: 1.89 (95% CI 0.58–3.2)
OBJECTIVE: The aim of this study was to test whether a physician-supervised web-based app, integrated with an electronic medical record, helps in improving blood pressure (BP) management in clinical practice. MATERIALS AND METHODS: An observational study of 1633 patients seen at a hypertension clinic managed by an endocrinologist with two cohorts (726 adopted the app and 907 had not). The app allowed patients and doctors to monitor BP, blood sugar and other vital signs. Patients decided whether to opt in to using the app and how often to upload their readings. The provider could offer feedback and communicate with patients through the app. We evaluated the change in office-based BP measurement before and after app adoption (at least 12 months apart). We performed a difference-in-difference analysis along with matching based on patient-individual characteristics. RESULTS: The difference-in-difference estimates were 6.23 mmHg systolic 95% confidence interval (95% CI) 0.87-11.59 for patients with SBP 150 mmHg or above, 4.01 mmHg systolic (95% CI 1.11-6.91) for patients with SBP 140 mmHg or above, 4.37 mmHg diastolic (95% CI 1.06-7.68) for patients with DBP 90 mmHg or above, 1.89 mmHg systolic (95% CI 0.58-3.2) and 0.87 mmHg diastolic (95% CI 0.17-1.57) overall for an average patient. Higher frequency of app usage was also associated with a greater reduction in BP. CONCLUSION: Use of an mHealth app in a clinical practice, was associated with a significant reduction in BP for average patients as well as high-severity patients. Physician-supervised mHealth apps in a clinical practice could be instrumental in managing patient BP.
Agnihothri et al. (2021) conducted a cohort in Hypertension (n=1,633). Physician-supervised web-based mHealth app vs. No app adoption was evaluated on Change in office-based blood pressure measurement (MD 1.89, 95% CI 0.58-3.2). Use of a physician-supervised mHealth app was associated with a significant overall reduction in systolic blood pressure (difference-in-difference 1.89 mmHg; 95% CI 0.58-3.2) for an average patient.
