Diagnosis of adrenal insufficiency in children: a survey among pediatric endocrinologists in North America
Bibliographic record
Abstract
OBJECTIVES: Adrenal insufficiency (AI) is a life-threatening condition where an accurate diagnosis is critical. While the ACTH stimulation test is the diagnostic test of choice, there remains uncertainty around its protocols and interpretation of results. In this context, the objective of this study was to understand practices of North American pediatric endocrinology providers on the diagnosis of AI in children. METHODS: An anonymous electronic survey was sent to members of the Pediatric Endocrine Society. RESULTS: A total of 221 participants were included. The majority practiced in academic centers (78%). All respondents ordered ACTH stimulation tests. While 85% used high-dose ACTH stimulation tests (HDST) to diagnose primary AI, there was less consistency in the choice of tests (HDST vs. low-dose ACTH stimulation test; LDST) when diagnosing secondary AI. When interpreting results, 95% used peak cortisol levels, 70% considered the clinical picture, and 49% used relative increase in cortisol levels. Median (IQR) cortisol cutoff level after ACTH stimulation test that was considered sufficient was 18 (15.5-18) μg/L [496 (428-496) nmol/L]; 17% used different cutoffs for LDST, and 18% used different cutoffs for newborns. Finally, 47% were unaware of the assay that was used in their institution for cortisol measurements. CONCLUSIONS: Pediatric endocrinology providers use ACTH stimulation tests variably, including in the choice between HDST vs. LDST, test protocols, and interpretation of results.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
