Paediatric haematopoietic stem cell transplantation research priorities: Results from an international multi‐stakeholder priority setting partnership

Summary Co‐designed research in paediatric HSCT is limited. We sought to determine research priorities which represent the shared priorities of patients, parents, carers and healthcare professionals (HCP) within Australia, New Zealand, the Netherlands and the United Kingdom. An international, multiphase priority‐setting methodology was implemented in partnership with the James Lind Alliance and delivered over an 18‐month period. Part 1: an international scoping survey asked respondents to submit their research uncertainties related to paediatric HSCT. Part 2: summarising and evidence‐checking the submitted uncertainties. Part 3: interim prioritisation survey. Part 4: consensus workshop. In the first international scoping survey, 667 topic ideas were suggested (45% by consumers, 55% by HCP), which were categorised into 80 summary questions. After systematic literature review, 35 summary questions were judged to be true uncertainties (i.e. not answered by existing evidence). These 35 uncertainties were included in a second interim prioritisation survey and completed by 224 participants. From those, a shortlist of 19 questions was drawn. After a multistakeholder workshop, consensus was reached on the top 10 priorities. The PSP identified important research gaps in the management of paediatric HSCT. Priority areas included: implementing personalised medicine approaches, improving immune recovery and adjunct interventions such as exercise, nutrition and microbiome‐directed strategies.
