Backgrounds
Health-care
workers’ (HCWs) exposure to bodily fluids puts them at risk of hepatitis B
virus HBV infection. This study investigated HBV vaccination practices and
outcomes in HCWs and assessed postvaccination seroprotection across HCWs in
different departments.
Methods
A
survey of HCWs in a Chinese public general hospital was carried out with a
retrospective cohort of 1420 hospital HCWs (458 males and 962 females). HBV
vaccination status (10-μg/dose used) was investigated in the cohort from
vaccination records from the period of 1988 to 2008. Blood samples were
collected and tested for hepatitis B surface antigen (HBsAg) and HBV antibodies
(anti-HBs).
Results
The
overall vaccination (complete course) and HBsAg carrier rates among HCWs were
40.42 % (574/1420) and 6.13 % (87/1420), respectively. Vaccination
rates differed by department, with HCWs in internal medicine (39.5 %) and
emergency (42.0 %) departments having particularly low rates. The natural
infection rate was 7.53 % (107/1420) among HCWs. HCWs in the department of
infectious diseases (vaccination rate, 57.8 %) had the highest rate of
antibody produced by natural infection (88.2 %).
Conclusion
The
vaccination rate was a disappointingly low among HCWs in Pearl River Delta Area
of China. HCWs working in infectious diseases departments and technicians were
at particularly likely to have been infected with HBV. A concerted effort is
needed to bring vaccination rates up among Chinese HCWs in Pearl River Delta Area of
southern China.
