Effectiveness of Mobile Health Interventions on Management of Patients with Hypertension: Systematic Review of Systematic Reviews (Preprint)
BACKGROUND Mobile health (mHealth) has provided a powerful platform for chronic disease management recent years. Although some previous systematic reviews evaluated the effectiveness of mHealth on hypertension management, there were inconsistent findings. OBJECTIVE To systematically evaluate the effectiveness of mHealth interventions on the management of patients with hypertension and to provide recommendations for the clinic and future researches. METHODS Databases including Embase, Cochrane Library, CINAHL, CNKI, SinoMed, WanFang and VIP Database were searched to collect systematic reviews and meta-analysis on mHealth interventions for hypertension management. Two researchers independently screened the articles and extracted data, and the Measurement Tool to Assess Systematic Reviews (AMSTAR 2) was used to evaluate the methodological quality of the included reviews. RESULTS A total of 11 systematic reviews were included. Three reviews were rated as high quality, four moderate quality, three low quality, one critically low quality. Mobile phone was the most common intervention type, followed by the internet. Seven reviews performed meta-analysis and showed that mHealth was associated with significant reduction in SBP from 2.28mmHg(95%CI 0.66-3.90; I2=100%) to 14.77 mmHg(95%CI 11.76-17.77; I2=90%) and DBP from 1.50mmHg(95%CI 0.80-2.20; I2=62%) to 8.17 mmHg(95%CI 5.67-10.67; I2=86%). Self-management behaviors included medication adherence, diet, smoking, alcohol drinking, exercise and BP monitoring, there were inconsistent results on the effectiveness of mHealth interventions. CONCLUSIONS The mHealth interventions can improve BP control in patients with hypertension, but its impact on self-management behaviors is not confirmed.
