The impact of psychoeducational interventions on the outcomes of caregivers of patients with heart failure: A systematic review and meta-analysis

Background: Heart failure is a global health care problem that causes a significant economic burden. Despite medical advancements, it's prognosis remains poor as many patients with heart failure experience symptoms that negatively impact Quality of Life. Caregivers are often responsible for helping and supporting family members manage their heart failure symptoms at home. In addition to managing their own medical problems and maintaining social and personal lives, significant burden and stress can occur. At present, caregivers receive little guidance or information to support them in their caregiving role. Objectives: This review aims to determine the impact of psychoeducational interventions on the outcomes of caregivers of patients with heart failure. Design: Systematic review and meta-analysis. Data source Five electronic databases: PsycINFO, Medline, CINAHL Plus, EMBASE and SCOPUS were searched from June 2007 to August 2019. Review methods The conduct and reporting of this review was based on the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The Cochrane Risk of Bias Tool was used to assess the risk of bias amongst randomised controlled trials, and the Newcastle Ottawa Scale was used to assess risk of bias in one quasi-experimental study. Results: Ten articles met the inclusion criteria, consisting of seven studies, with a total sample size of 953 participants. The pooled result from two studies, conducted in America and China, reported that psychoeducational interventions significantly reduced depression at six months' follow-up (SMD -0.82; 95% CI -1.17 to -0.47; p = 0.73, I2 =0%). The pooled result from two studies conducted in Sweden and Taiwan showed a significant improvement in heart failure knowledge at six months' follow-up (SMD 0.97; 95% CI 0.70 to 1,25; p < 0.00001, I2 =0%). Finally, pooled results from three studies conducted in Sweden, China and Taiwan found a significant improvement in Quality of Life at 3 months' follow- up (SMD 0.25; 95% CI 0.25 to 0.48; p = 0.03). The three most common intervention components included: group based educational sessions, telemonitoring and telephone support, and written resources. Conclusions: There was no specific type of psychoeducational intervention found to have a significant impact on caregiver outcomes, as interventions were heterogeneous consisting of multiple components. Further research is needed to determine the effectiveness of individual and combined components to identify the ideal intervention format and design for caregivers of patients with heart failure.
