WITHDRAWN: Parents' Experiences of Navigating Diagnostic Uncertainty in Children With Rare Diseases: A Narrative Inquiry

BackgroundApproximately 300 million people worldwide live with a rare disease, and the majority of rare diseases manifest in childhood. For families, the period before diagnosis is often protracted and distressing, marked by repeated consultations, inconclusive investigations, conflicting medical opinions, and the absence of a recognisable name for their childs condition. While the clinical and epidemiological dimensions of the diagnostic odyssey have been documented, the narrative and experiential dimensions of how parents live through and make sense of prolonged diagnostic uncertainty remain underexplored, particularly in low- and middle-income country contexts. AimTo explore the narrative experiences of parents navigating diagnostic uncertainty for children with rare diseases in Brazil. MethodsA narrative inquiry informed by the three-dimensional narrative space framework of Clandinin and Connelly was conducted. Sixteen parents (twelve mothers and four fathers) of children who had experienced a diagnostic delay of at least two years were recruited from two rare disease referral centres in Sao Paulo and Belo Horizonte. Data were collected through two narrative interviews per participant, supplemented by participant-produced timelines and family photographs. Analysis followed a narrative analytical approach attending to temporality, sociality, and place. FindingsThree narrative threads were woven across the parents stories: (a) "Living in the space before the name," capturing the disorienting experience of caring for a child whose suffering could not be categorised, explained, or predicted; (b) "Fighting to be believed," describing the relentless advocacy required to sustain medical attention in a system that struggled to accommodate conditions falling outside familiar diagnostic categories; and (c) "Rewriting the story," illuminating how the eventual arrival (or non-arrival) of a diagnosis reshaped parents understanding of their child, their family, and themselves. ConclusionDiagnostic uncertainty for parents of children with rare diseases is not a passive waiting period but an active, effortful, and identity-transforming experience. The findings highlight the need for healthcare systems to provide structured psychosocial support during the pre-diagnostic period and for clinicians to develop communication practices that acknowledge, rather than dismiss, the legitimacy of undiagnosed suffering.
