Background
Despite the availability of a safe and effective vaccine coupled with the awareness of the potential risk of Healthcare Workers acquiring Hepatitis B Virus infection, some HCWs never get vaccinated. Generally, hepatitis B vaccination coverage globally is below the expected level as adherence has remained poor in various healthcare settings, especially in developing countries. The objective of this study was to assess the completion of a three-dose Hepatitis B virus vaccination cycle and associated factors among healthcare workers in the Greater Accra Region of Ghana.
Methods and materials
An analytical cross-sectional study was conducted and included 363 healthcare workers selected using probability sampling procedures. The participants were recruited from five facilities within the Greater Accra Region in the first half of 2018. A pretested questionnaire was used to collect data which was analyzed using SPSS version 21. The proportion of healthcare workers receiving the recommended 3 doses of the hepatitis vaccine was computed. The multivariable analysis procedure identified the factors associated with adherence to the receipt of three doses of the hepatitis B vaccine. Odds ratios were estimated with corresponding confidence intervals with the level of significance set at 0.05.
Results
A total of 340 sample units were included in the analysis. Most of the participants (252/340, 74.1%) were females, mainly nurses/midwives (162/340, 47.6%) with a mean age of 34.5 (SD ±7.7). A high proportion of the participants (82.7%) have tertiary/post-tertiary level education and ever participated in at least one training workshop on the prevention of blood-borne infections (80.6%). Overall vaccination uptake was 60.9% (207/340) (95% CI = 55.7%-66.1%). Complete vaccination coverage (three doses) was 46.8% (159/340). High-risk perception (AOR = 4.0; 95% CI = 1.3–12.5), and previous training in infection prevention (AOR = 2.8; 95% CI = 1.1–7.5) were significantly associated with adherence to receipt of three doses of hepatitis B vaccine.
Conclusion
Adherence to three-dose hepatitis B vaccination cycles is not universal among the healthcare workers in the Greater Accra Region. Receipt of the three-dose regimen is significantly associated with high-risk perception and attendance of training in infectious disease prevention. Interventions to increase risk perception and training in the prevention of blood-borne infections could improve adherence to complete/full vaccination protocol among healthcare workers who are at constant risk of exposure to the hepatitis B virus.
