Key result
Messaging-based mHealth linked to ~19-point better MLHFQ scores in heart failure clinic care.
Why the study?
The impact of an instant messaging-based mHealth application integrated with HF clinic care on emergency department visits, hospitalizations, and quality of life in HF patients over one year needed to be evaluated.

Does an instant messaging-based mHealth application integrated with heart failure clinic care improve quality of life and reduce emergency department visits and hospitalizations in patients with chronic heart failure?
Integrating a widely accessible, instant messaging-based mHealth platform into routine heart failure clinic care was associated with substantial improvements in quality of life and a more than 60% reduction in emergency department visits and hospitalizations over one year in a Thai cohort.

Associated with fewer ED visits and hospitalizations in HF; hypothesis-generating and requires randomized confirmation before practice change.
Objective: To evaluate the impact of an instant messaging-based mobile health (mHealth) application integrated with heart failure (HF) clinic care on emergency department (ED) visits, hospitalizations, and quality of life (QoL) in HF patients over one year.Material and Methods: A retrospective cohort study was conducted at Songklanagarind Hospital, Thailand, including 88 HF patients who used an instant messaging-based HF application for self-care monitoring between 2021 and 2025. ED visits, hospitalizations, and Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores were compared before and after the intervention using zero-inflated Poisson regression and paired t-tests. High usage was defined as ≥100 data submissions/year. Logistic regression analysis was performed to identify the factors associated with a favorable treatment response.Results: Post-intervention, ED visits decreased from 2.01 ± 1.80 to 0.75 ± 1.20 events/year (IRR=0.37, 95% CI [0.28, 0.49], p < 0.001), while hospitalizations decreased from 1.69 ± 1.00 to 0.56 ± 0.92 events/year (IRR=0.33, 95% CI [0.24, 0.45], p < 0.001). MLHFQ scores improved from 50.8 ± 22.6 to 31.9 ± 24.3 (mean difference=18.9, 95% CI [14.8, 23.0], p < 0.001). High-usage patients demonstrated greater QoL improvement (p = 0.01). Patient clinical status, particularly functional severity, was associated with treatment response.Conclusion: Integration of an instant messaging-based mHealth application with HF clinic care significantly reduced healthcare utilization and improved QoL in Thai HF patients. Patient clinical status may influence responsiveness to the intervention, highlighting the importance of individualized care. These findings support mHealth adoption in Thailand’s healthcare system.

Charoensin et al. (2026) conducted a cohort in Chronic heart failure (n=88). Instant messaging-based mHealth application (Line Official Account) integrated with HF clinic care vs. Pre-intervention baseline (1 year prior to application use) was evaluated on Pre-post difference in Minnesota Living with Heart Failure Questionnaire (MLHFQ) score over 1 year (MD 18.9, 95% CI 14.8, 23.0, p=<0.001). Instant messaging-based mHealth integrated with HF clinic care improved MLHFQ scores by 18.9 points and reduced hospitalizations over one year.
