Abstract
This study examines the effect of SMS-based interventions on medication adherence and blood pressure. The inclusion criteria were randomized controlled trials and quasi-experimental designs for SMS-based interventions excluding online messaging applications between 2010 and 2022, in English, with participants clinically diagnosed with hypertension on anti-hypertensive medication, aged 18 and above, regardless of comorbidities. PubMed, Google Scholar, and EBSCOHost were used for the search. A risk of Bias assessment was done. Out of the 5,503 articles identified, 11 studies were quality-assessed using the Cochrane risk of bias tool and systematically reviewed. Seven studies were included for the quantitative assessment and analyzed using the continuous random effects model. SMS based interventions are estimated to increase medication adherence scores by SMD 0.28 (95% CI, 0.12 to 0.44, p = 0.0005) and decrease systolic blood pressure by SMD -0.11 (95% CI, -0.20 to -0.02, p = 0.02). However, it has no benefit in diastolic blood pressure reduction SMD 0.00 (95% CI, -0.25 to 0.24, p = 0.98). Thus, SMS-based interventions can be considered to improve adherence and BP outcomes among patients with hypertension, especially in low-resource settings.
