Hepatitis B Vaccination after Occupational Exposure among Healthcare Workers in a Tertiary Hospital in Delhi
Introduction: Hepatitis B virus (HBV) is a bloodborne virus which can be transmitted via percutaneous and mucocutaneous
exposure to infected body fluid. Healthcare workers (HCWs) who are continuously exposed to different body fluids are
at an increased risk of contracting and transmitting this virus. It is thus important to evaluate and highlight: Knowledge
of post-exposure management strategies and first aid following exposure to blood and bodily fluids, Prevalence of
Hepatitis B infection among HCWs, Hepatitis B vaccination rates and post-exposure prophylaxis, Post-vaccine immune
status of HCWs.
Material and Methods: An Observational, Individual Based, Cross-sectional Survey was carried out in a tertiary care
teaching hospital in india. Stratified Sampling technique was utilized to select participants.
Results: Only 59% of the respondents got their Hepatitis B titres measured after 2 months of vaccination. 41% did not
get their anti-Hbs titres measured post-immunisation. Alarmingly, 23% did not even know that anti-Hbs titres are to be
measured. It was disturbing to note that 21% still capped needles with both hands and were unaware about safe capping
techniques like One-Hand Scoop Technique. On being asked first aid measures to be administered to contaminated
percutaneous needle/sharp injury, 25% wrongly advised that the site will be washed with alcohol. 3.9% even disclosed
that they have poured sodium hypochlorite on sites where they have been pricked with a contaminated needle. Perhaps
the most shocking revelation that highlighted the dire need for postexposure first-aid came when respondents agreed
that mouth splashed with blood/bodily fluids should be rinsed with soapy water (11.8%) repeatedly, rinsed with alcohol
based disinfectant (13.2%).
Conclusion: Majority of the study respondents did not demonstrate a satisfactory level of awareness and attitude
regarding Hepatitis B transmission and prevention. 89.5% doctors stated that they did not undergo post-exposure
prophylaxis in the form of Hepatitis B Vaccination.
