Routine sterile glove and instrument change at the time of abdominal wound closure to prevent surgical site infection (ChEETAh): a pragmatic, cluster-randomised trial in seven low-income and middle-income countries.

Lancet 2022; 400: 1767-1776.

In this study that included over 13,000 procedures, this simple change reduced the rate of surgical site infection from 18.9 to 16 per cent, P=0.0032.

Comment: I really like studies that appear simple and generalisable. Hospitals around the world with the highest infection rates stand to see the biggest differences.
