Effect of <i>eTansiyon</i> smartphone application on hypertension control

Abstract

Abstract Aim: To investigate the effectiveness of eTansiyon smartphone application in blood pressure control in patients with hypertension. Background: Global prevalence of hypertension and the burden of chronic illness care, especially in primary care, are increasing in world. We have developed eTansiyon to ensure the continuity of patient-physician relationship, so it may help to improve the lifestyle of patients with hypertension, increase their adherence to treatment and achieve the target blood pressure. Methods: This study was a non-randomized controlled study. The sample was selected by random sampling method among the patients registered in 6 Family Health Units (FHUs). Randomization was performed at the FHU level; the units were randomized to 4 control group (CG) and 2 intervention group (IG), so that randomization in this study was 2:1. Both groups were followed up for at least four months. In addition to CG, IG were provided to use eTansiyon . Obtained data were analysed to evaluate differences between groups at the beginning and end of the study, intra-group changes after follow-up and interaction between groups and follow-up period. Findings: The study was performed with 124 patients in CG and 61 patients in IG. At the end of the study, the average systolic blood pressure/diastolic blood pressure (SBP/DBP) of office and home was significantly lower in IG compared to CG ( P &lt; 0.001, MD 9.5 mmHg; P = 0.007, MD 3.8 mmHg; P &lt; 0.001, MD 10.6 mmHg; P &lt; 0.001, MD 4.8 mmHg, respectively), and it was found that the proportion of people with target blood pressure in IG was significantly higher than CG ( P &lt; 0.001, 49.2%( n = 30) and 22.6%( n = 28), respectively). Repeated measures ANOVA and generalized estimating equations results showed that follow-up period and interaction between groups were significant in terms of office and home SBP/DBP and target blood pressure level during follow-up period ( P &lt; 0.001, P &lt; 0.001, P &lt; 0.001, P &lt; 0.001, P &lt; 0.024, respectively).
