A Closer Look at Urinary Tract Infection Prescribing Patterns in a Suburban Emergency Room Department
Bibliographic record
Abstract
Background. Antimicrobial stewardship has become an area of increasing concern due to the rising numbers of inappropriate antibiotic prescribing. Urinary tract infections (UTIs) were the fifth highest diagnosis for emergency department (ED) visits in Canada for 2011. Patients diagnosed with asymptomatic bacteriuria (ASB) are often inappropriately prescribed an antibiotic(s) in 80% of cases. The purpose of this investigation was to inform administration, prescribers, pharmacists and other allied health workers on the current state of antimicrobial prescribing surrounding UTIs, and to measure the impact of regular reporting on patient outcomes and appropriate antimicrobial prescribing. Methods. A retrospective chart audit of 309 admissions was conducted on patients who presented to the Strathcona Community Hospital emergency department (Sherwood Park, Alberta, Canada) between July and October 2015 with UTI symptoms. The primary outcome was antibiotic prescribing concordance to current practice guidelines, which included (but not limited to): Infectious Diseases Society of America (IDSA), Bugs & Drugs, Towards Optimized Practice (TOP), and Alberta Health Services (AHS) Drugs & Therapeutic Backgrounders (DTB). Secondary outcomes include UTI symptoms and diagnoses documented in the ED charts, antimicrobial orders, hydration status, urine investigations completed, and frequency of specific pathogens grown. Results. Overall, 97% of UTI related admissions resulted in an ordered antimicrobial. The majority of the antimicrobial prescribing in the ED was non-concordant to guidelines (63%). Patients did not receive follow-up for negative cultures, resulting in 29% of the non-concordance. Of all patients reviewed, 22% demonstrated ASB or had syndromes inconclusive of UTI. Ciprofloxacin was the most frequently ordered antimicrobial (27%). Figure 9. Cluster chart of UTI cases, concordance, and initial antimicrobials prescribed. Conclusion. Audit results have demonstrated a need to engage the ED healthcare team in an effort to improve the diagnosis and treatment of UTI. Disclosures. All authors: No reported disclosures

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.
