Post-operative Infection: Study of the Efficacy of Plain Soap and Water Versus Alcohol-based Rubs for Surgical Hand Preparation

2014-08-27 03:18:58 | BioPortfolio


Surgical site infections (SSI) constitute a significant health-economic and clinical challenge. The investigators conducted a cluster-randomized, cross-over study to compare the efficacy of plain soap and water (PSW), used ubiquitously across sub-Saharan Africa for surgical hand preparation, to alcohol-based hand rub (ABHR), with SSI rates as the main outcome measure.

A total of 3133 patients undergoing clean and clean-contaminated surgery were included in the study and followed up for 30 days.


We generated power calculations assuming a 2-sided alpha error (Type 1) of 0.05 and a power of 80%. We performed power calculations using a statistical model for a cluster-randomized trial with 8, 10, or 12 clusters including 6 operating rooms each, with different levels of reduction (10%, 30% and 50%) in SSI rates in those periods that implemented the ABHR strategy compared to conventional PSW.
