Abstract

Background: Heart failure has high mortality and is linked to substantial burden for patients, carers and health care systems. Patients with chronic heart failure frequently experience recurrent hospitalisations peaking at the end of life, but most prefer to avoid hospital. The drivers of hospitalisations are not well understood.

Aim: We aimed to synthesise the evidence on factors associated with all-cause and heart failure hospitalisations of patients with advanced chronic heart failure.

Design: Systematic review of studies quantitatively evaluating factors associated with all-cause or heart failure hospitalisations in adult patients with advanced chronic heart failure.

Data Sources: Five electronic databases were searched from inception to September 2020. Additionally, searches for grey literature, citation searching and hand-searching were performed. We assessed the quality of individual studies using the QualSyst tool. Strength of evidence was determined weighing number, quality and consistency of studies. Findings are reported narratively as pooling was not deemed feasible.

Results: In 54 articles, 68 individual, illness-level, service-level and environmental factors were identified. We found high/moderate strength evidence for specialist palliative or hospice care being associated with reduced risk of all-cause and heart failure hospitalisations, respectively. Based on high strength evidence, we further identified black/non-white ethnicity as a risk factor for all-cause hospitalisations.

Conclusion: Efforts to integrate hospice and specialist palliative services into care may reduce avoidable hospitalisations in advanced heart failure. Inequalities in end-of-life care in terms of race/ethnicity should be addressed. Further research should investigate the causality of the relationships identified here.
