Prevalence of hepatitis C antibodies among healthcare workers of two teaching hospitals. Who is at risk?

Abstract
Blood samples taken from Nottingham hospital staff for measuring hepatitis B surface antibody levels from January 1994 to October 1995 were identified from the virology computer and matched to data from the occupational health database by record linkage using surname, first name, date of birth, and date of blood test. The database included main occupational group, age, sex, and place and type of work. A unique study number was attached to the combined data set and all identifying features were removed. Microsoft Access 2.0 was used as the database and for record linkage and spss for Windows for the statistical analyses.
