Question and Methods: This study assessed non-inferiority between sterile and non-sterile technique for traumatic lacerations requiring EM-physician suture repair using a 2% margin.
Findings: Infection rate for non-sterile technique (5.7% (95% CI 4.0% to 7.5%)) was non-inferior compared to sterile (6.8% (95% CI 5.1% to 8.8%)); mean difference: -1.1% (95% CI −3.7% to 1.5%).
Limitations: Every patient had skin disinfected with chlorohexidine which is not everyone’s clinical practice.
Interpretation: The study was not underpowered due to upper bound CI in mean difference <2. There is no difference in infection rate between the two techniques.
