Objective To assess the rate of vaccination against hepatitis B among the hospital staff of the University Hospital of Sidi Bel Abbes (SBA).

Methods This is a retrospective descriptive study including all hospital staff of the University Hospital of Sidi Bel Abbes on 6-month period from January 1st to June 30th 2015.

The data collection was done using a questionnaire pre etablished filled by two occupational physicians from the medical records of occupational health and hepatitis B immunisation registry. The questionnaire included several components :

socio-demographic characteristics (age, sex …)

Professional characteristics : workstation, professional category, Professional seniority, service … Professional history (notion of blood exposure accidents, hepatitis B or C)

Vaccination status: noting the doses received by each subject.

Results The study population is represented by 2222 employees, the average age was 41.38 ± 9.1 years with a female predominance (56.9%), seniority at work was 12 ± 9.3 years.

Nurses accounted for more than half of hospital staff.

About 2222 workers, more than half were regularly vaccinated against hepatitis B (53.6%) and 6.5% were being vaccination.

The staff at high-risk services seems best vaccinated.

Conclusion Vaccination against viral hepatitis B remains insufficient. raising awareness about the risk of blood exposure accidents and the use of personal protection seem indispensable.
