Strength in Shared Experiences: A Meta-Synthesis of Qualitative Studies on Peer Support in Haematologic Cancer.

Objectives: Peer support can improve the disease and treatment processes of patients with haematologic cancer. This meta-synthesis aimed to systematically synthesize and interpret the qualitative evidence on how patients experience peer support throughout their illness trajectory.

Methods: This study employed a systematic qualitative meta-synthesis design, using the thematic synthesis approach described by Thomas and Harden. The databases Web of Science, EBSCOhost/CINAHL Complete, MEDLINE, Cochrane Library, ProQuest, PubMed, Scopus, ScienceDirect, and Springer Link were searched up to February 2025. Eligible studies were appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research.

Results: Eight qualitative studies published between 2003 and 2024, with 129 participants across 4 countries, were included. The analysis yielded 4 analytical themes: psychological empowerment, emotional support, provision of information and guidance, and reconstruction of the recovery process.

Conclusion: This meta-synthesis suggests that peer support plays an important role in enhancing the emotional and psychological well-being of patients with haematologic cancer. Peer interactions help reduce fear, uncertainty, and loneliness while strengthening resilience, fostering practical coping strategies, and cultivating a sense of community and hope.

Implications for nursing practice: Peer support programs provide emotional resilience and practical guidance by alleviating fear, uncertainty, and loneliness among patients with haematologic cancer. The integration of structured peer support interventions into clinical practice may enhance the psychosocial outcomes of patients, promote empowerment, and support long-term survivorship.
