To ensure the safety of patients and healthcare workers (HCWs), national recommendations are for HCWs to have access to vaccines and serological testing to assure protection against vaccine-preventable diseases (VPDs). We sought to determine measles and hepatitis B immunity status of HCWs in small Victorian public healthcare facilities, and to evaluate program differences according to hospital size or location.
Healthcare facilities were required to participate in a point prevalence survey of HCW hepatitis B immunity status in 2016 – 2017 and HCW measles immunity status in 2017-2018. NHMRC-defined staff categories were used for HCW classification: Category A staff were reviewed for hepatitis B immune status, and Categories A, B and C were reviewed for measles immune status.
A total of 51 healthcare facilities reported HCW hepatitis B immunity, corresponding to a total of 6,633 HCWs. Of these, median facility evidence of immunity was 59.5%, with 11.1% reporting unknown status. A total of 75 healthcare facilities reported HCW measles immunity, corresponding to a total of 17,522 HCWs. Of these, median facility evidence of immunity was 66.7%, with 26.1% unknown. Confirmation of measles immunity was highest in hospitals with largest workforce (>200-500 and >500 HCW).
Despite availability of national guidelines for vaccination of HCWs, implementation remains a challenge. Enhanced and strengthened HCW measles immunisation programs must be prioritised in smaller facilities (<200 staff). Both Hepatitis B and Measles immunity programs must focus upon documentation of status, as well as screening of both existing and new employees.
