RESUMO
INTRODUCTION: Chronic respiratory diseases represent a significant burden of disease globally, with high morbidity and mortality. Individuals living with these conditions, as well as their families, face considerable physical, emotional and social challenges. Palliative care might be a valuable approach to address their complex needs, but evidence to prove this is still scarce. OBJECTIVES: This systematic review aimed to study the effectiveness of palliative care interventions in health-related outcomes (quality of life, symptom control, symptom burden, psychological well-being, advance care planning, use of health services, and survival) in chronic respiratory patients. METHODS: Pubmed, Cochrane and Web of Science were searched for trials published in the last 10 years, comparing palliative care interventions to usual care, in patients with chronic respiratory diseases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. RESULTS: Eight studies were included, seven randomized controlled trials and one cluster-controlled trial; the former with moderate risk of bias and the latter with high risk of bias. Findings revealed that palliative interventions improve breathlessness control and advance care planning. There were no significant differences for the other outcomes. CONCLUSIONS: Palliative care appears to have a beneficial effect on breathlessness, one of the most distressing symptoms in patients suffering from chronic respiratory diseases and allows for advanced care planning. Additional research, with more robust trials, is needed to draw further conclusions about other health-related outcomes.
