The REaCT–NSQIP single-centred feasibility study was completed in Q2 2019. Given that the statistical power of the study is dependent on the baseline SSI rate across participating sites, the SSI rate of the NSQIP-ON Collaborative (which includes >40 hospitals in the trial region of Ontario) will be reassessed at the midpoint of trial enrolment (≈Q3 2021), allowing for adjustment of the final sample size.
