Methods of laceration closure in the ED: A national perspective

Laceration closure is one of the most common procedures performed in the emergency department (ED). While sutures and staples have been the traditional wound closure device, topical skin adhesives (TSA) were introduced in the United States 20 years ago as a non-invasive alternative for simple, low-tension wounds. We determined which closure devices were used to close ED lacerations and explored patient and provider characteristics associated with choosing TSA. We also tested the hypothesis that use of TSA would be associated with shorter ED length of stay (LOS) than sutures/staples.

We extracted demographic and clinical data on all patients with a laceration from the publicly available website of the National Hospital Ambulatory Medical Care Survey for the years 2012-2015. This database is provided by the National Center for Health Statistics of the CDC. Based on weighted sampling, national estimates are made for all ED visits in the US. We determined the association between patient characteristics (age, sex, insurance type, geographic location, laceration site, type of ED provider) and use of TSA. We also compared ED LOS between patients whose wounds were closed with TSA or sutures/staples using the t-test and a linear regression model.

There were an estimated 540 million ED patient visits, and 26.1 million patients (4.8%) had at least one laceration. Of the 15.4 million patients with a single laceration, 9.2 million were closed with either sutures/staples (7.2 million), TSA (1.5 million), or both (0.5 million). Mean (SE) age was 30 (1) years, 63% were male and 42% were under age 18 years. Lacerations were on the upper extremity (42%), face (30%), lower extremity (14%) and scalp (8%). Of patients with a single laceration closed with either TSA or sutures/staples, use of TSA did not differ by age, sex, year, geographic location or wound site. ED LOS was significantly shorter in patients whose wounds were closed with TSA (101 ± 7 vs. 136 ± 4 min; P < 0.001). After adjusting for potential confounding variables, use of TSA was associated with a 26 (95% CI 9-44) minute shorter ED LOS (P = 0.004) then sutures/staples.

Topical skin adhesives are used in about 1 of 4 wound closures in the ED. Use of TSA did not differ based on demographic characteristics or wound site. Use of TSA is associated with a shorter ED LOS than sutures/staples.
