The diagnostic odyssey: insights from parents of children living with an undiagnosed condition

Background: People living with rare disease often have protracted journeys towards diagnosis. In the last decade, programs have arisen around the world that are dedicated to ending this ‘diagnostic odyssey’, including the Undiagnosed Diseases Program Western Australia (UDP-WA), which has a focus on finding diagnoses for children and young adults. To explore the lived experience of the diagnostic journey semi-structured interviews were conducted with parents of 11 children at commencement of their involvement in the UDP-WA. Results: Thematic analysis revealed three main themes that captured parents’ experiences and perspectives. Parents reported (i) the need to respond to significant care needs of their children, which span not only the health system but other systems such as education and disability services. In doing so, parents become the navigator, expert and advocate for their children. Meanwhile, parents are on (ii) the diagnostic odyssey—the rollercoaster of their journey towards diagnosis, which includes various names applied to their child’s condition, and the impact of no diagnosis. Parents described their views on (iii) the value of a diagnosis and the outcomes they expect to be associated with a diagnosis. Conclusion: Analysis showed an overall significant perceived value of a diagnosis. Our study provides new perspectives on the concept of diagnosis and indicates that parents may benefit from supports for their child’s care needs that are beyond the scope of the UDP-WA.
