Objectives To synthesize qualitative research on the information needs of relatives of childhood cancer patients and survivors. Methods Systematic searches of PubMed, PsycINFO, CINAHL, and Scopus identified relevant literature. Extracted data were combined using thematic synthesis. Methodological quality was assessed using the JBI critical appraisal tool for qualitative research. Results The review included 27 publications, with most research focusing on parents or primary caregivers. Five areas of information needs were identified: treatment, medication, and care; general information about cancer; coping and support; follow-up, late effects, and rehabilitation; and parenting and everyday life. Appropriateness of information depended on health care professionals' aptitude, message characteristics, communication setting, and relatives' personal factors. Preferences for form, sources, and timing for information provision varied. Conclusion The review identified information needs, communication barriers, and preferences among caregivers and siblings of childhood cancer patients and survivors, highlighting areas requiring further research and clinical consideration in addressing the identified challenges. Practice implications Caregivers and siblings have unique but similar information needs regarding childhood cancer. To ensure that these needs are met, health care professionals could use eHealth and mHealth technologies, assess each family member's knowledge, and create a safe and supportive environment for questions and feedback.+ ID der Publikation: unilu_68757 + Sprache: Englisch + Letzte Aktualisierung: 2023-10-17 12:19:5
