There are an increasing number of children with complex healthcare needs who require continuous technological support to sustain their lives and there is a scarcity of empirical data on the influences and interactions at the point of the initiation of this technology. An evidence-based theoretical construct is required to articulate and contextualise the levers and penalties of the initiation of this technology. TechChild asks just because we can, should we? and how are the influences on the initiation of technology dependence understood in contrasting health, legal, and socio-political systems? TechChild will be a step change in how we understand the coexistence of humans with an increasing availability of technological augmentations. This is urgent in a society where this debate predominantly happens in the public domain with limited opportunity for healthcare professionals to offer their perspective. TechChild will revolutionise how we conceive access to care and offers a research horizon that questions cultural relativism in a cyborg era. This project elicits the probability of factors likely to influence the initiation of technology dependence, leading to the development of a theory of technology initiation. This ground-breaking exploration will inform technology initiation across the lifespan with implications for healthcare, bioethics, education, parenting, policy making, and legal.
