Effectiveness of telemonitoring on clinical outcomes in patients with heart failure: a randomized clinical trial

Year: 2026

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: Given the advancements in information technology in recent years, there is a possibility of implementing technology-based interventions to train, monitor clinical outcomes, and improve patients with heart failure (HF) ‘s self-care abilities. This study was conducted to determine the effectiveness of telemonitoring on clinical outcomes of patients with HF. In this parallel randomized clinical trial with blinded outcome assessment and data analysis, 136 patients with HF were allocated to intervention or control groups. The intervention group received structured telemonitoring, education, and weekly follow-up for eight weeks. Self-care (primary outcome) was measured using the European Heart Failure Self-Care Behavior Scale, and medication adherence (secondary outcome) was assessed using the Medication Adherence Rating Scale at baseline and four weeks post-intervention. A total of 136 patients were enrolled, and 123 completed the study (intervention = 61; control = 62). Baseline demographic characteristics and outcome measures were comparable between the two groups. Following the intervention, self-care scores significantly improved in the intervention group compared with the control group (p < 0.001), with a large effect size (Cohen’s d = − 1.26; 95% CI − 1.64 to − 0.87). Medication adherence also showed a significant improvement in the intervention group compared with the control group after adjusting for baseline values (p < 0.001), with a moderate-to-large effect size (Cohen’s d = 0.73; 95% CI 0.37 to 1.10). Structured telemonitoring was associated with improvements in self-care and medication adherence in patients with HF. These findings suggest that technology-based follow-up programs may support better patient engagement and clinical outcomes. Further studies are needed to confirm the long-term benefits and sustainability of these interventions.Trial Registration: IRCT20230221057476N1 (Date 28/06/2023).
