Annual influenza vaccination of healthcare workers (HCWs) is an important component of infection prevention programs within healthcare facilities. The Victorian Department of Health and Human Services have supplied influenza vaccines for HCWs since 2005. In 2014, the target vaccination uptake was increased from 60% to 75% of HCWs and this was introduced as a key performance indicator. The objective of this study is to describe vaccine uptake between 2005 and 2015.
Annual data submitted to the Victorian Healthcare Associated Infection Surveillance System (VICNISS) regarding HCW influenza were evaluated for 2005-2015. Facility uptake – the number of vaccinations administered (or reported to have been given elsewhere) divided by total number of staff employed – was reported as a statewide aggregate and stratified by facility size (number of staff employed).
In 2015, 88,815 HCWs were vaccinated across 99 healthcare facilities, corresponding to an overall uptake of 78.6%. During 2005–2015, small facilities (<100 HCWs) generally reported highest uptake while larger facilities (≥800 HCWs) recorded lowest uptake. Larger facilities have recorded the greatest increase in uptake since the target has been set, (20.1%) between 2013 and 2015. For all healthcare facility size categories, the highest uptake was observed in 2015.
Influenza vaccination uptake in HCWs has successfully been introduced as a performance indicator in Victorian healthcare facilities and a peak uptake was reported in 2015. Varied trends are evident when uptake is stratified by number of employed HCWs, providing a feasible and meaningful method for benchmarking.
