The Management of Outpatient Cellulitis at The Moncton Hospital before and after the Initiation of a Clinical Treatment Pathway
Bibliographic record
Abstract
Antimicrobial Stewardship is a coordinated effort to improve and measure the appropriate use of antimicrobials. Antibiotic resistance is an emerging world health problem and unnecessary prescribing of broad-spectrum antibiotics is a major contributor to this. Skin and soft-tissue infections are a common reason to receive a prescription for antibiotics. Currently there exists a trend for using broad-spectrum intravenous antibiotics for moderate to severe infections when more narrow-spectrum options would be adequate. This study aimed to characterize the choice of antibiotic being prescribed for the management of outpatient cellulitis requiring intravenous antibiotics and evaluate the success of a clinical order set outlining optimal therapy. This study was a retrospective chart review looking at antibiotic prescribing through the Emergency Department at The Moncton Hospital, in Moncton, New Brunswick. Charts were reviewed before and after the introduction of a clinical order set outlining optimal antibiotic therapy. The goal was to review charts from the pre- and post-intervention group and compare antibiotic usage, treatment failure rates, and adverse events. Of the 54 patients receiving IV antibiotics in the pre-intervention group, 3 received cefazolin, 50 received ceftriaxone, while 1 received levofloxacin. The median duration of IV therapy was four days. After the introduction of the clinical order set there was an absolute increase of 53.8% (n = 35) in the use of cefazolin and absolute decrease of 53.7% (n = 23) in the use of ceftriaxone in the post-intervention group of 59 patients. Both results were statistically significant (P < 0.001). The median duration of IV therapy in this group was 3.5 days. In eligible patients, the clinical order set was utilized 61.1% of the time. There was no significant difference in rates of treatment failure or adverse events between cefazolin and ceftriaxone. The introduction of a clinical order set outlining the preferential use of once-daily cefazolin plus probenecid for the treatment of outpatient cellulitis lead to a statistically significant increase use of cefazolin, and decrease use of ceftriaxone, thus demonstrating a positive stewardship effect at a local level.

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.
