Samenvatting

BACKGROUND: In geriatric oncology, family members frequently accompany patients during medical consultations, providing emotional and practical support while participating in shared decision-making (SDM). Family involvement in SDM can facilitate the decision-making process but also pose challenges for healthcare professionals. Additionally, much of the SDM deliberation occurs outside the clinical setting, making it important to understand family dynamics to ensure treatment decisions align with the patient's values and preferences. Therefore this study aims to explore the experiences and perspectives of family members regarding their involvement in decision-making processes for older patients with cancer, and the subsequent impact on roles and family dynamics. METHODS: Qualitative open in-depth interviews were conducted with 16 family members of 11 patients with cancer of 70 years and older in the Netherlands. Qualitative data analysis was conducted using a thematic analysis approach. RESULTS: Four interconnected themes emerged. The first theme, "Roles" revealed that family members often provide both practical and informational support, and sometimes act as advocates for the patient. The second theme, "Family Values and Beliefs," highlighted a strong sense of unconditional and reciprocal support within families, emphasizing the core value of caring for one another. Third, "Family Dynamics," encompasses: keeping everyone informed, dividing caregiver tasks, dealing with disappointment and sadness, managing different opinions, and coping with uncertainty. Finally, "Dilemma's" describes: family members balancing their own opinions with the patient's preferences, reconciling hope and fear, weighing trust in medical professionals against their own judgment, and balancing caregiving responsibilities with their personal lives. These dilemmas were shaped by roles the family members assumed, the underlying values and beliefs, and family dynamics. CONCLUSION: The findings of this interview study provide valuable insights into the complex roles that family members of older patients with cancer play in medical consultations and treatment decision-making and their dilemma's. These roles are deeply influenced by family values and dynamics, which can significantly shape decision-making processes and outcomes. Understanding these factors can help healthcare professionals as it highlights the evolving responsibilities of family caregivers and the importance of supporting them in navigating the intricacies of treatment decisions while maintaining respect for patient autonomy.
