A tool to facilitate spirometry quality control assessment using 2019 standards
Bibliographic record
Abstract
<b>Rationale:</b> The 2019 ATS/ERS spirometry standards provide objective and subjective manoeuvre acceptability criteria. Subjective components may lead to discordance among expert reviewers. A tool using the 2019 criteria was developed to give reviewers a common approach to determine test acceptability and facilitate a decision consensus. <b>Methods:</b> The tool, which incorporates artificial intelligence quality assessment, applied the objective acceptability criteria and displayed key points (FEV1, end-expiration) on F-V and V-T graphs to aid reviewers in assessing contours and identifying anomalies. The tool evaluates and reports FEV1, FVC, BEV, plateau volume, expiratory time, rise time and inspired volume following EOFE (FIVC). Subjective assessments were: achievement of maximal flow and volume; occurrence of cough, glottis closure or any anomaly in 1st second of expiration; and glottis closure or early termination after 1 s of expiration. Reviewers complete a yes/no check box for each criterion. The tool calculates whether the manoeuvre is acceptable or usable. <b>Results:</b> Three reviewers used the tool to assess 150 tests. 50 were repeated to assess intra-rater reliability, (Kappa: 0.83, 0.86 and 0.80). All reviewers agreed on 63% of 100 unique tests (Kappa=0.5). Using the tool to develop reviewer consensus on each test, the individual agreement with the consensus was 88%, 94% and 70%. <b>Conclusion:</b> Despite using a set of strong objective criteria defined by the spirometry standards, intra- and inter-rater disagreement in assessing spirometry manoeuvre acceptability persists. The developed tool can be used as a powerful way to standardise assessment and reduce variability, and its additional benefits are being investigated

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.
