Evaluation in real life of 'suivi-hta', a free application for home blood pressure monitoring

Objective: Home Blood Pressure Monitoring (HBPM) is key to improve blood pressure control. To help hypertensive patients adopt HBPM and doctors use the results in their practice, the French ‘Fondation de Recherche en Hypertension Artérielle’ has developed the Suivi-HTA application, available since September 2020. We therefore aimed at carrying out a first real-life evaluation of the utilization of this application among hypertension specialists and their patients. Design and method: The survey was carried out in France between October 2020 and March 2021 in 8 hospitals and 2 private practices based on a standardized questionnaire assessing the acceptability and effective use of the application, as well as the doctor's opinion on patient satisfaction. Results: The survey included 135 hypertensive patients, 38% were women, 57% were over 55 years old. Only 27% regularly performed HBPM. If the application was offered, it was well accepted (women 65%, men 80%) with a more important rejection rate in hypertensives over 55 years old (26% vs. 3%, p<0.0003) and with more comorbidities (31% vs. 7%, p = 0.0005). Rejection was mainly related to digital technology (no smartphone or tablet, lack of knowledge on downloading or using applications). Among the 113 patients who agreed to test the application, 98 (87%) effectively performed HBPM, 77 (67%) did so using Suivi-HTA, of which 60 (53%) generated and transmitted a HBPM report. According to the doctor's opinion, 88% patients who have used Suivi-HTA will be future users of the application. Patient satisfaction with the application was assessed as “good” for 93% patients. Conclusions: This national survey shows that the Suivi-HTA application has a good rate of acceptance and effective use among hypertensives. It also generates a very positive opinion in the medical community. However, age and presence of comorbidities were risk factors for reduced acceptance, in connection with the difficulties to digital accessibility. It would therefore be interesting, while globally promoting the use of HBPM in hypertensive patients, to develop specific strategies targeting patients with more comorbidities and/or at higher cardiovascular risk.
