The direct medical costs associated with suspected (confirmed and negative) heparin-induced thrombocytopenia
Bibliographic record
Abstract
Purpose. The objective of this study was to identify and quantify the direct medical costs associated with suspected (confirmed and negative) heparin-induced thrombocytopenia (HIT) from a Canadian hospital perspective. Conclusions. This is the first study to quantify the costs associated with suspected HIT cases. These cases increase the costs of hospital care. Results. Confirmed HITT cases incurred substantially greater average costs ($34,155, range $358-$202,069, n=12) than confirmed HIT cases without thrombosis ($4,575, range $39-$16,373, n=8). The average cost of a negative HIT case was $119 (range $39-$4,181, n=88). Methods. A cost of illness analysis was conducted in patients with suspected HIT during 2005. Resource utilization variables included: (1) laboratory tests to investigate HIT, (2) HIT-safe anticoagulant use, (3) diagnostic imaging for HIT with thrombosis (HITT), and (4) additional hospital days attributed to HIT. The average cost per case of confirmed HIT, confirmed HITT, and negative HIT was calculated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
