"I want to see them thrive!": exploring health service research priorities for young Aboriginal children growing up in Alice Springs - a qualitative study.

To better understand the specific influences of early life on the long-term health and well-being of local Aboriginal children in Alice Springs, high-quality local longitudinal data is required. The Central Australian Aboriginal Congress and the Murdoch Children's Research Institute are exploring the feasibility of establishing a cohort study to fill this gap. A nested qualitative study was conducted to identify priority issues that can be translated into research questions answerable through the proposed cohort study. Semi-structured interviews and focus group discussions (FGDs) were conducted with a range of key community stakeholders, parents and caregivers of young Aboriginal children from Alice Springs in the Northern Territory between 2020 and 2021. Two Aboriginal and two non-Aboriginal researchers conducted 27 interviews and 3 FGDs with 42 participants. Three broad themes were constructed through reflexive thematic analysis representing the areas of focus community stakeholders and parents want future research to prioritise: (1) social determinants of health (2) building positive connections, and (3) making sure kids grow up strong and healthy. Priority setting for future research should be driven by Aboriginal and Torres Strait Islander peoples in order to be of practical benefit to their community. This qualitative study found that housing, transport and positive connections through nurturing and engaged parents were some of the most important issues raised. Participants also wanted future research to focus on issues specific to children such as nutrition, hearing loss, language development and capacity to learn. These findings will guide future work led by local Aboriginal researchers to co-design the proposed cohort study.

Retrospective hospital based surveillance of intussusception in children in a sentinel paediatric hospital: benefits and pitfalls for use in post-marketing surveillance of rotavirus vaccines.

UNLABELLED: Evaluation of the safety of rotavirus vaccines, particularly with respect to the risk of intussusception, is recommended for countries planning to introduce rotavirus vaccines into the National Immunisation Program. However, as prospective studies are costly, require time to conduct and may be difficult to perform in some settings, retrospective hospital based surveillance at sentinel sites has been suggested as an option for surveillance for intussusception following introduction of rotavirus vaccines. OBJECTIVE: To assess the value of retrospective hospital based surveillance to describe clinical and epidemiological features of intussusception in children aged <24 months and to investigate any temporal association between receipt of a rotavirus vaccine and intussusception. METHODS: A retrospective chart review of all patients diagnosed with intussusception at Royal Children's Hospital, Melbourne, Australia over an 8-year period including before and after rotavirus vaccine introduction into the National Immunisation Program, was conducted using patients identified by a medical record database (ICD-10-CM 56.1). Patient profile, clinical presentation, treatment and outcome were analysed along with records of immunisation status obtained using the Australian Childhood Immunisation Register. RESULTS: A 9% misclassification rate of discharge diagnosis of intussusception was identified on critical chart review. The incidence rate of intussusception at the Royal Children's Hospital over the study period was 1.91 per 10,000 infants <24 months (95% CI 1.65-2.20). Intestinal resection was required in 6.5% of infants (95% CI 3.6%, 11.0%). Intussusception occurred within 30 days after vaccination in 2 of 27 patients who had received at least 1 dose of a rotavirus vaccine. CONCLUSIONS: Valuable data on the incidence, clinical presentation and treatment outcomes of intussusception can be obtained from data retrieved from hospital medical records in a sentinel paediatric hospital using standardised methodology. However, there are methodological limitations and the quality of the data is highly dependent on the accuracy and completeness of the patient information recorded, the system of coding and record retrieval.
