Effectiveness of integrated palliative care telehealth intervention in patients with chronic heart failure: A systematic review and meta-analysis of randomized controlled trials.

Background: Heart failure (HF) represents a substantial burden, impacting both health and financial domains. Despite the presence of evidence-based interventions for prevention and management, suboptimal care has been recognized as a critical contributor to adverse HF-related outcomes. We aim to analyze the impact of palliative care telehealth intervention compared to usual care in quality of life (QoL) and resource utilization of chronic HF patients.

Methods: We conducted a systematic search across various databases, including MEDLINE (via PubMed), Google Scholar, the Cochrane Library, and ScienceDirect to identify randomized controlled trials (RCTs) examining the impact of palliative care telehealth interventions on the QoL and health outcomes of HF patients from inception until May 2024. Statistical analysis was performed using RevMan 5.4, pooling odds ratios (OR), and weighted mean differences (WMD) via a random effects model for primary and secondary outcomes. The study protocol has been registered in PROSPERO (CRD42024542371).

Results: In our study, 16 RCTs involving 2,324 HF patients, averaging 69.2 years old, were included. Upon analyzing the primary outcome, QoL, assessed through the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Functional Assessment of Chronic Illness Therapy-Palliative Care (FACIT-Pal) Scale, we found a statistically significant improvement in QoL among patients who received palliative care or palliative care telehealth interventions compared to those who received usual care. The WMD for KCCQ was 3.56 (95% CI: 0.43 to 6.69, p = 0.03; I = 46%) and for FACIT-Pal was 2.54 (95% CI: 1.00 to 4.08, p = 0.001; I = 14%). Furthermore, HF patients receiving palliative care experienced a notable decrease in hospitalizations (OR: 0.60; 95% CI: 0.41 to 0.86; p = 0.006; I = 52%). However, we did not observe a significant change in all-cause mortality, with an OR of 1.22 (95% CI: 0.77 to 1.94, p = 0.39; I = 37%).

Conclusion: The implementation of palliative care telehealth interventions demonstrates a notable impact, positively influencing the QoL and decreasing hospitalization rates among patients with chronic HF.
