The focus was placed upon the adverse event of CLABSI infections and the CHG intervention. Table 5 demonstrates the frequency of CLABSI infection events for a year pre CHG intervention and was five occurrences up to this CLABSI [A9] prevention improvement project. The standard deviation (SD) of the sample for the occurrence of CLABSI after CHG intervention was calculated as the SD of 21.68

with a sample variance of 470. The SD of the sample of occurrences of CLABSI without the CHG intervention was calculated at 0.49 with a sample variance of 0.24. The frequency of CLABSI for the 12 months before the CHG intervention and the month post-intervention is displayed in Table 5. The most frequently occurring CLABSI events occurred pre CHG intervention in October 2018 with one reported
