Background
Hepatitis B vaccination is the most effective method of prevention for hepatitis B virus infection. It is a major public health problem in Nigeria, and health workers are at increased risk. This study determined the uptake of hepatitis B vaccination and assessed its determinants among health care workers (HCWs).
Methods
A hospital-based cross-sectional study was conducted between July and August, 2016 using self-administered structured questionnaires among 3132 HCWs in University of Nigeria Teaching Hospital, Enugu, South-East, Nigeria. Data was analysed using SPSS version 22. Binary logistic regression analysis was used to identify factors that influenced uptake of vaccination. Ethical clearance was obtained from the Research Ethics Committee of the health facility.
Results
The uptake of hepatitis B vaccination was 14.2% (n = 445). The number of doses received were: 3 doses (218/3132, 48.9%), 2 doses (71/3132, 16.0%), and one dose (156/3132, 35.1%). The reasons for non-uptake of vaccination included: cost of vaccine 48 (10.8%), ‘did not believe they could be infected’ 28 (6.6%), long vaccination schedule, and lack of time 150 (35.1%). The Odds for uptake of hepatitis B vaccination were 22% lower among nurses compared to doctors (AOR = 0.78, 95% CI = 0.54–0.98, P = 0.037). It increased with increasing age (AOR = 1.30, 95% CI = 1.08–1.59, P < 0.001), increasing duration of work in the hospital (AOR = 1.19, 95% CI = 1.09–1.32, P = 0.032), and was about twice higher among those that had tertiary education than others that had less education (AOR = 1.96, 95 CI = 0.76–5.07, P = 0.164).
Conclusions
The uptake of hepatitis B vaccination was low among HCWs in Enugu, Nigeria. Age, staff category, and duration of work in the hospital, were independently associated with hepatitis B vaccination. Provision of adequate hepatitis B surface antigen screening facilities and vaccination sites where the cost of vaccination is subsidized for all HCWs is recommended.
