This systematic review and meta-analysis assessed nurse-led telemonitoring versus usual care in adults with chronic heart failure, including randomized trials and observational cohorts. Across 18 studies (11 randomized trials and 7 cohorts; about 20,000 participants), telemonitoring was associated with fewer all-cause and heart-failure readmissions. Mortality results were less conclusive: randomized trials showed a nonsignificant trend favoring telemonitoring, whereas large real-world cohorts reported lower 1-year mortality among monitored patients. Interventions generally combined daily remote measurements with proactive nurse follow-up.
Key findings
- Across 18 studies, including about 20,000 participants, nurse-led telemonitoring was associated with fewer all-cause readmissions than usual care.
- Heart-failure readmissions were also lower with telemonitoring compared with usual care.
- Randomized trials showed a nonsignificant mortality trend favoring telemonitoring; large cohorts reported lower 1-year mortality among monitored patients.
Why it matters
Readmissions are a substantial concern in chronic heart failure, and these pooled findings suggest that remote monitoring paired with nurse review may help reduce hospital use. The differing mortality results by study design warrant caution: observational survival differences do not establish a treatment effect, and randomized evidence has not demonstrated a significant mortality benefit.
What to keep in mind
The review included both randomized trials and observational cohorts, with common performance bias. The authors call for adequately powered trials with longer follow-up and standardized intervention components.
