Hepatitis B screening in a Northern Irish mental handicap institution: relevance to hepatitis B vaccination

Abstract

The current DHSS guidelines on immunisation against hepatitis B in mental handicap hospitals recommend vaccination for personnel at risk directly involved in patient care (who may have direct contact with patients or their body fluids) and for new admissions into institutions where the incidence is known to be high. We report a serological survey of hepatitis B markers in over 99% of the residents of a large mental handicap hospital. Of 720 patients tested only one carried hepatitis surface antigen. This patient was anti-HBe positive. Only 4·5% of the residents carried any hepatitis marker. These results do not suggest the need for a local vaccination programme for patients or staff.
