Description
Summary:ABSTRACT BACKGROUND A new national donor safety initiative was introduced in Australia in 2018, which aimed to encourage all whole blood donors to water load and to use applied muscle tension. This study evaluated the effect of this initiative on the rate of vasovagal reactions (VVR). STUDY DESIGN AND METHODS Routinely collected data were used to identify whole blood donations and any associated VVRs before (n = 167,056 donations) and after implementation (n = 215,572 donations). Multivariate logistic regression analyses were performed to evaluate the differences in VVR rates. RESULTS The total rate of VVRs declined from 22.5 per 1000 donations to 20.6 per 1000 donations after implementation, a reduction of 8% (p
