BackgroundThe purpose of thispaper is to explore the experiences of parents and carers of children with chronic health conditions in accessing healthcare during the Covid-19 pandemic. Children with chronic conditions typically rely on both planned and unplanned care, and contact with healthcare professionals over extensive periods of time. Their distinct care needs render these children vulnerable to even to minor changes in healthcare provision. The wide-ranging care disruptions during the pandemic were therefore likely drastically to affect their health and wellbeing; an assessment of the effects of Covid-19 policies on healthcare access and quality of care delivered for this group is needed.MethodsFrom 25/01/2022 to 25/05/2022, four focus groups were held with parents/carers of children with diabetes, neurodivergence, mental health conditions, and medical complexities to explore their experiences in navigating the healthcare system during the pandemic. Interviews were transcribed and then subjected to thematic analysis using NVivo qualitative research software.ResultsOur results indicate that children with chronic health conditions (and their parents/carers) experienced difficulties accessing healthcare during the pandemic. Problems with late diagnosis, prolonged waiting times, and deficiencies with telemedicine were identified, as were impacts of healthcare disruptions on children’s wellbeing, and the wellbeing of wider families. We found that children with neurodivergence and those with mental health conditions were particularly affected with their health needs repeatedly de-prioritised. Furthermore, the loss of contact with multi-specialty clinical teams profoundly affected parents and carers, leaving them feeling isolated in managing their children’s health. These diminished relationships became another vector for uncertainty in supporting children’s health.ConclusionThe effects of healthcare disruptions on the welfare of children with chronic conditions (and their families), are well evidenced in this work, providing deeper understandings of the relationships between these children, their families and clinicians. The evidence in this paper aims to inform future policy and ethical guidelines so that the needs of children with long-term health conditions can be properly considered in times of crisis.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12913-023-09452-1.
