Survey of Australian general paediatricians regarding insulin initiation practices in children with new onset of type 1 diabetes.

Aim: Australian and New Zealand (NZ) paediatric endocrinologists' and NZ general paediatricians' insulin initiation strategies for children with type 1 diabetes (T1D) was recently described. The aim of this study was to document the insulin initiation practices of Australian general paediatricians in newly diagnosed children with T1D.

Methods: An online survey was sent to Australian general paediatricians identified through the Australian Paediatric Society diabetes database.

Results: Twenty four general paediatricians participated on behalf of their Australian regional and metropolitan diabetes units managing 2059 patients. The diabetes units averaged 86 patients and all practices were multidisciplinary models of care. Intensive insulin therapy regimens were initiated at diagnosis for children age 2-10 years by 93% respondents compared with 73% Australian endocrinologists, 17% NZ endocrinologists and 36% NZ general paediatricians. Carbohydrate counting as part of flexible bolus dosing was usual practice for 83% of respondents, which was substantially more than Australian endocrinologists (63%), NZ endocrinologists (64%) and NZ general paediatricians (33%).

Conclusion: Almost all Australian general paediatricians who completed the survey initiate intensive insulin therapy regimes with carbohydrate counting in newly diagnosed children with T1D, consistent with the 2018 evidence-based recommendations of the International Society of Pediatric and Adolescent Diabetes. A substantial proportion of children with T1D within Australia are managed by general paediatricians who tend to align with international peak body guidelines.
