Abstract
Background: Hepatitis B infection is usually higher among health workers than the general
population, particularly in the sub-Saharan region. WHO recommends vaccination for all
health care workers (HCWs) against the highly infectious, blood borne virus: HBV.
However, previous studies reported that knowledge of HCWs toward the hepatitis B
infection, Hepatitis B vaccine and their vaccination coverage was low and vary among HCWs
in different settings.
Objective: This study was aimed to assess knowledge about HBV infection, HBV vaccine
and status of HBV vaccination among healthcare workers in TASH, Addis Ababa, Ethiopia
from March 10 to September 10, 2020.
Methods and materials: Hospital based cross-sectional study was conducted on 358 HCWs
who were selected randomly. Stratified random sampling method was used to collect the data
using self-administered questionnaire. Then, the data was entered into Epi-data 4.2 version
and was exported to Statistical Package for Social Science (SPSS) version 26 for analysis. All
covariates that showed p value < 0.25 in binary logistic analysis were further analyzed by
multiple logistic regressions to detect true predictors.
Result: Among the health care workers, who participated in this study, 180 (51.4%) of them
had adequate knowledge on the HBV infection. Medical doctors were the most
knowledgeable among the HCWs, with interns [AOR=11.3(95% CI=4.5-28.6)], consultant
physicians [AOR=7(95% CI=3.1-15.9)] & resident physicians [AOR=3.5(95% CI=1.9-6.9)]
being significant predictors of good knowledge. Vaccination coverage was 60% which was
predicted by a shorter work experience [AOR=4.7(95%=1.4-5.8)].
Conclusion: This study reveals that general knowledge level of HCWs about HBV is
inadequate and vaccine coverage is suboptimal. Thus, concerned stakeholders should devote
more efforts to improve the HCWs awareness about the virus and role of its vaccine and also
more work to avail vaccine.
