Economic Evaluation of the Addition of Vancomycin to Cefazolin Prophylaxis in Patients Undergoing Arthroplasty.
Trial report in PharmacoEconomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe addition of a glycopeptide antimicrobial to cephalosporin therapy has been reportedly adopted in practice to prevent surgical site infections (SSIs). We conducted an economic evaluation from the healthcare sector perspective to assess the cost-effectiveness of adding vancomycin to cefazolin prophylaxis in patients undergoing arthroplasty.
methodsData were collected over 180 days in a randomised controlled trial conducted at 11 hospitals in Australia, involving 2044 patients assigned to vancomycin and 2069 to placebo, both in addition to cefazolin. Health utilities were measured using EQ-5D-3L at baseline and 30 days, 90 days, and 180 days post-surgery. Healthcare costs (Australian dollars [AU$]; 2022 values) were estimated using Medicare claim data and hospital administrative records. Bootstrap was used to estimate means and 95% confidence intervals (CIs) of healthcare costs and quality-adjusted life years (QALYs). The net monetary benefit framework was used to construct a cost-effectiveness acceptability curve.
resultsOver 180 days, 96 SSIs occurred in the vancomycin group, and 79 in the placebo group. Mean QALYs were 0.392 (95% CI 0.389-0.395) in the vancomycin group and 0.394 (95% CI 0.391-0.397) in the placebo group. Mean total healthcare costs were AU$5184 (95% CI 4926-5480) in the vancomycin group and AU$5018 (95% CI 4772-5293) in the placebo group. Using willingness-to-pay and willingness-to-accept thresholds from AU$0 to AU$3,000,000, the probability of vancomycin being not cost-effective ranged from 0.79 to 0.87.
conclusionsAdding vancomycin to cephazolin prophylaxis in arthroplasty is most likely not cost-effective. Omitting vancomycin could lead to substantial annual savings for the healthcare sector without compromising health outcomes.
