Abstract

BACKGROUND
Hepatitis B is a viral infection of the liver and causes both acute and chronic disease. It is transmitted through contact with an infected person's bodily fluids. It is an occupational hazard for healthcare workers and can be prevented by the administration of a vaccine. It is recommended that healthcare workers be vaccinated against vaccine preventable diseases including hepatitis B. The study objective was to determine the prevalence and determinants of hepatitis B vaccination among healthcare workers in selected health facilities in Lusaka.
METHODS
The study took place in seven health facilities across Lusaka district in Zambia. A total sample size of 331 healthcare workers was selected of which; 90 were nurses, 88 were doctors, 86 were laboratory personnel and 67 were general workers. A self-administered structured questionnaire was given to a total of 331 healthcare workers. Investigator led stepwise approach was used to select the best predictor variables in a multiple logistic regression model and all analyses were performed using STATA software, version 12.1 SE (Stata Corporation, College Station, TX, USA).
RESULTS
Only 64(19.3%) of the healthcare workers were vaccinated against hepatitis B, with 35 (54.7%) of these being fully vaccinated and 29 (45.3%) partially vaccinated. Analysis showed that; age of the healthcare worker, sharp injuries per year and training in infection control were the variables that were statistically significant in predicting a healthcare worker's vaccination status.
CONCLUSION
It is reassuring to learn that healthcare workers have knowledge regarding hepatitis B and the vaccine and are willing to be vaccinated against it. Health institutions should bear the cost for vaccinating staff and efforts should be made for appropriate health education regarding hepatitis B infection and its prevention. Establishment of policies on compulsory hepatitis B vaccination for healthcare workers in Zambia is recommended.
