Background: Although palliative care is expanding globally for patients with serious illness, Turkey has not had widespread integration of early concurrent oncology palliative care. Hence, adapting and testing models of concurrent oncology palliative care for Turkish patients is imperative. Furthermore, it is critical that these care models also address the needs of family caregivers. Objective: To assess needs and elicit suggestions that would inform the adaptation of the ENABLE (Educate, Nurture, Advise, Before Life Ends) evidence-based early palliative care model for Turkish family caregivers of older persons with cancer. Methods: Formative evaluation study. Semi-structured interviews were conducted with 25 primary family caregivers of older individuals with cancer. Thematic analyses yielded themes in four domains: meaning of caregiving, effect of caregiving, education and consulting needs, and preferences about the delivery of the ENABLE model of palliative care support. Results: Caregivers described the impact of the cancer on their daily lives and responsibilities in the areas of physical, psychological, work, social, and family life. Caregivers emphasized their needs for information about symptoms, physical care, cancer pathology, and prognosis. Regarding the ENABLE model of early concurrent palliative care, participants wanted encounters to be in-person with educational material support that was simple and focused on disease information (prognosis, medication, handling emergency situations), psychological support, caring, nutrition, and acquiring community services. Conclusion: Themes from this study will be used to modify the ENABLE intervention protocol for future pilot and efficacy testing in Turkish caregivers.
