The hidden patient. When children have chronic illness, what happens to their parent’s health?

Abstract

Approximately 25% of Canadian children live with a chronic condition, yet their parent caregivers remain invisible within a healthcare system that recognises only the child as the patient. This presentation argues that parent caregivers of children with chronic illness constitute hidden patients whose biological, behavioural, and socioeconomic deterioration demands recognition within routine clinical encounters. Utilising Barr et al.’s (2003) Expanded Chronic Care Model, which positions the family unit, rather than the individual, as the locus of care across porous clinical-community boundaries, this work synthesises current evidence to demonstrate that caregiving-related health decline is not incidental but predictable and preventable.

Biologically, chronic caregiving stress dysregulates the HPA axis, leading to elevated cortisol levels and systemic inflammation (Mountcastle et al., 2023). On the other hand, according to Gallagher & Bennet (2021), the resultant allostatic load reliably forecasts illness and disability. Expanding on this idea, Khan et al. (2025) indicate that modifications to the HPA axis could be transmitted across multiple generations. Behaviourally, parents’ roles as caregivers involve sacrificing their health while maintaining near-perfect medication adherence for their children (Cohn et al., 2020). As a result, this creates a cascade of chronic diseases that remain untreated or hidden. Systemically, Canadian health policy does not recognise caregivers as patients, rendering their deterioration invisible in both funding and practice.

Through case-based application, this presentation demonstrates that nurses are uniquely positioned to disrupt this trajectory through brief validated screening tools, trauma-informed relational practice, and advocacy for two-generation care models that treat parent and child as an interconnected unit.
