Omission of prophylactic cefuroxime 1.5 g before transperineal prostate biopsy,
does it really help with Noninferiority for sepsis or urinary tract infection requiring hospitalization within two months?

30-Second Summary
B
Evidence Grade B · 72 · Safety acceptable
Cefuroxime omission did not increase hospital-requiring infection after transperineal biopsy
No increase in serious infection was seen in selected low-risk transperineal biopsy patients. Infection symptoms require prompt assessment, and this evidence does not apply to transrectal biopsy.
What the
research shows
The grade is B with 72 points. Hospital-requiring sepsis or UTI occurred in 0 patients in both groups, risk difference 0 points (95% CI -1.37 to 1.37). The upper bound was below the prespecified 4-point noninferiority margin.
What the
ads claim
Reducing antibiotic exposure lowers individual adverse effects and population selection pressure for resistance. Verdict 2402 is C with 56 points and asks about cefazolin timing in cesarean delivery, not antibiotic omission in transperineal biopsy. `1175` concerns the same antibiotic, cefuroxime, but asks whether direct intracameral administration at the end of cataract surgery prevents endophthalmitis. This verdict asks whether systemic prophylactic antibiotics can be omitted before transperineal prostate biopsy. These are entirely different questions.

Useful facts when choosing a product

  • Biopsy used an outpatient transperineal MRI-TRUS fusion approach under local anesthesia.
  • Cefuroxime was intramuscular in Norway and intravenous in Germany.
  • The result does not apply to transrectal biopsy or high-risk infection patients.

What the research actually shows

NORAPP randomized 555 patients at two Norwegian and German hospitals and analyzed 553 eligible randomized participants after excluding two with an unknown allergy. It was open label, not placebo-controlled or double-blind, but the primary endpoint required hospitalization and was not counted as an unblinded subjective endpoint. Limitation name: noninferiority design. Listed item: prespecified margin 4 percentage points. Avoidability: possible - a larger superiority or equivalence design could rely less on an accepted increase in infection. Small study (<200) does not apply (553); substantial attrition (>=15%) was 2/555 (0.36%) and does not apply. Oslo University Hospital and Vivantes Klinikum Am Urban provided public-hospital funding.

02

Why this is classified as B (72)

A hospital-requiring infection endpoint, public funding, 553 analyzed participants, and a met 4-point margin are strengths; one noninferiority trial limits the grade to B with 72 points.

Counterpoint. Zero versus zero does not mean zero risk; each group had a 95% CI upper bound of 1.37%.

Rejudgment record. New verdict — Zero hospital-requiring infections in both transperineal groups, 553 analyzed participants, a 1.37-point CI upper bound, and a prespecified 4-point margin

Sub-claim grades by effect

This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

Cross-check — AI research and Codex final gate

AI was used for research and drafting. Blind grading, adversarial audit, and the methodology boundary rules were then reapplied before Codex performed the final evidence, grade, copy, and build checks. If a grade cannot be narrowed, both evidence positions and their reasons are published.
