The roles and experiences of informal caregivers in non-malignant respiratory disease at the end of life: A thematic synthesis of qualitative studies

OBJECTIVES: The aim of this review was to identify, review, and synthesize primary qualitative literature to answer the question "what are the roles and experiences of informal caregivers providing care to a person with non-malignant respiratory disease at end of life from the perspectives of the caregiver and recipient of care?" METHODS: This qualitative systematic review was undertaken using thematic synthesis. Electronic databases (British Nursing Database, Cumulative Index to Nursing and Allied Health Literature Plus, Medline, PsycInfo, ProQuest Sociology, Allied and Complementary Medicine Database [AMED]) covering nursing, medicine, and social sciences were systematically searched from inception to October 2024. Studies were included if they reported data on the experiences and roles of caregivers in non-malignant respiratory disease at end of life, from the perspective of the caregiver or the person with non-malignant respiratory disease. Twenty-two papers met the eligibility criteria and were included in the review. Quality assessment was undertaken using the JBI Critical Appraisal Checklist for Qualitative Research. RESULTS: The findings illustrated the complexity of the caregiving role and highlight unmet needs during the end of life stage. SIGNIFICANCE OF RESULTS: This evidence synthesis highlights the significant contribution caregivers make in the lives and deaths of those with non-malignant respiratory disease. Challenges of caregiving in this context increase the stress of caregivers, including unpredictable disease progression and difficult symptoms such as breathlessness. There are persistent inequalities between malignant and non-malignant care pathways. Caregivers would welcome more recognition and information from healthcare professionals to support their role.
