TREATMENT OF ASYMPTOMATIC UTI IN OLDER DELIRIOUS MEDICAL INPATIENTS: A PROSPECTIVE COHORT STUDY
Bibliographic record
Abstract
Despite clinical practice guidelines, asymptomatic bacteriuria in older people is commonly treated because of a change in mental status. We sought to determine how often asymptomatic urinary tract infection (UTI) is treated in older delirious individuals, and whether treatment is associated with functional recovery. Consecutive older medical in-patients were screened for delirium, and followed in hospital. Of 343 delirious in-patients, 237 (69%) had poor functional recovery (death, new institutionalization or decreased function at 3 months). Ninety four (27%) were treated for asymptomatic UTI, which was associated with poor recovery compared to those who were not (RR 1.30, 95% CI: 1.14–1.48 overall; RR 1.34). Clostridium difficile infection was significantly more common in the treated group (n=7, 7.5%) compared to the untreated group (n=8, 3.2%), OR 2.45, 95% CI: 0.86–6.96. Treatment of asymptomatic UTI in older delirious medical in-patients was common, and potentially harmful. Further research is needed to validate these findings.

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.
