Australasian Paediatric Endocrine Group

Recommendations from the Australasian Paediatric Endocrine Group on measuring circadian hormones, short stature and delaying puberty.

Do not routinely measure insulin-like growth factor binding protein 3 (IGFBP-3) for workup and diagnosis of childhood short stature.

Particularly given its low sensitivity, insulin-like growth factor binding protein 3 (IGFBP-3) does not significantly contribute to the diagnosis of childhood short stature resulting from growth-hormone deficiency (GHD), which can lead to the under identification of GHD. It should therefore not be used as a routine measure for the workup and diagnosis of children with short stature. However, IGFBP-3 testing may have a role, along with IGF-1 testing, as an auxiliary diagnostic index for provocative testing.

How this list was made How this list was made

A working group of lead clinicians from APEG brainstormed an initial list of 11 low-value practices in paediatric endocrinology and a preliminary review of the evidence for each was undertaken. An online survey was developed based on these 11 recommendations along with a summary of the evidence for each, and circulated to APEG members for their feedback. For each recommendation, respondents were asked to assign a score from 1 to 5 (where 1 = strongly disagree and 5 = strongly agree) on two criteria: ‘The recommendation is evidence based’ and ‘The recommendation is relevant to paediatric endocrinology in Australasia’. Based on the recommendations which received the highest average total scores, and after a final in-depth review of the related evidence, the final top five were chosen and approved by APEG.
