Utilisation of neonatologist‐performed echocardiography in shock among neonatologists with interest in haemodynamic: International survey
Bibliographic record
Abstract
AIM: Neonatologist-performed echocardiography (NPE) is recommended during shock. We aimed to assess factors associated with NPE utilisation in the NICU and physiological information obtained during management of shock. METHODS: An Internet-based survey, sent to neonatologists with interest in haemodynamics, studying NPE utilisation in shock management through a real clinical case and correlating its use with responders' training and NICU settings. RESULTS: Fifty-nine completed surveys were received from the United Kingdom: 38%, Western Europe: 32%, Canada: 23% and other countries: 7%. Whilst managing the given clinical case, 90% of responders expected first NPE to exclude congenital heart disease-although only 61% could exclude it confidently (71% in trained clinicians vs. 29% without training; p < 0.01). NPE utilisation prior to initiate treatment was significantly correlated with mean number of neonatologists able to perform NPE in the NICU (4.9 vs. 2.9 neonatologists per unit; p = 0.02). Similarly, for ongoing therapeutic guidance, NPE was more used in trained clinicians (p < 0.01). 88% and 81% of responders studied a combination of multiple parameters to assess filling and systemic flow, respectively. CONCLUSION: Neonatologist-performed echocardiography during shock management differs with previous training and number of doctors able to perform echocardiography in NICU. This study highlighted the need for enhanced training implementation.

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.
