Promotion of healthcare personnel vaccinations among newly employed doctors and nurses: Evidence-guided strategy.

OBJECTIVE

Healthcare personnel vaccinations are important to prevent vaccine-preventable diseases in hospitals. We evaluated the seroprevalence, vaccination rates, and barriers to vaccination among newly employed nurses and doctors.

METHODS

A cross-sectional study was conducted at a university hospital in the Republic of Korea from 2017 to 2020. The immune status for hepatitis B virus (HBV), varicella zoster virus (VZV), and hepatitis A virus (HAV) was tested. HBV, VZV, measles, mumps, and rubella (MMR) vaccinations were mandatory. HAV and tetanus-diphtheria-pertussis (Tdap) vaccinations were also recommended by specialists. A web-based survey on factors affecting vaccination completion was conducted.

RESULTS

For the 668 participants, the mean age was 26 ± 2 (±SD) years. Seroprevalence was 86% for HBV, 93% for VZV, and 59% for HAV. Vaccine completion rates were 40% for HBV, 70% for VZV, 65% for MMR, 42% for HAV, and 70% for Tdap. Overall compliance for mandatory vaccines was 54%. A total of 402 subjects who had worked for over one year were surveyed, with a 22% response rate. More than 50% of respondents gave the following reasons for not receiving recommend vaccines: 1) they were busy (77%), 2) vaccination process was complicated (68%), and 3) they simply forgot about vaccination (55%). Healthcare personnel agreed to be frequently informed of immunization requirements and for monitoring of vaccination rates.

CONCLUSION

Vaccination compliance among newly employed doctors and nurses was 54%. Active interventions such as simplifying the vaccination process and frequent notifications are needed to achieve optimal immunization rates.
