Suspected GHB Overdoses in the Emergency Department
Bibliographic record
Abstract
Blood specimens from 146 suspected gamma-hydroxybutyrate (GHB) overdose cases, presenting to an emergency department in Washington State over a 12-month period, were analyzed for GHB and other drugs. Of these 146 patients, GHB was confirmed in approximately one-third of the patients (N = 54), sometimes in potentially toxic concentrations. These patients were aged between 17 and 59 years (median 28 years), and 83% were male. Blood GHB concentrations ranged from 29 to 490 mg/L (mean 137 mg/L; median 103 mg/L). In 36 (67%) of the 54 patients, other drugs were additionally detected. Ethanol was measured in 22 (41%) patients, with concentrations ranging from 0.01 to 0.26 g/100 mL (median 0.04 g/100 mL). Other commonly co-administered drugs included 3,4-methylenedioxymethamphetamine, marijuana, methamphetamine, cocaine, and citalopram. Frequently observed clinical symptoms on admission for the GHB overdose group included copious vomiting, ataxia, lack of gag reflex, respiratory depression, mild acute respiratory acidosis, unconsciousness, and sudden altered states of consciousness. Many patients required intubation, and several became combative and required restraints. The majority of patients were discharged within 6 h of hospital admission. However, despite presenting with similar clinical symptoms on admission, GHB was not confirmed in 92 of the 146 overdose patients, suggesting that GHB overdose cases may frequently be indistinguishable from other drug overdoses or medical conditions.

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.
