The role and potential of bioethics input when a child requires the initiation of technology dependence to sustain life is relatively unknown. In particular, little is understood about the meaning physicians give to bioethics as a source of support during the care of children in pediatric intensive care who require long-term ventilation (LTV). We used a hermeneutic phenomenological approach to underpin the collection and analysis of data. Unstructured interviews of 40 physicians in four countries took place during 2020. We found that elements of trust, communication and acceptance informed the physicians’ perceptions of the relationship with bioethics. These ranged from satisfaction to disappointment with their input into critical decisions. Bioethics services have potential to help physicians gain clarity over distressing and complex care decisions, yet physicians perceive the service inconsistently as a means of support. This research provides a sound basis to guide more beneficial interactions between clinicians and bioethics services.
