Document Details : Title: An outbreak of nosocomial hepatitis B virus infection in a nursing home for the elderly in Antwerp (Belgium) Author(s): DE SCHRIJVER K, MAES I, VAN DAMME P, TERSAGO J, MOËS E, VAN RANST M Journal: Acta Clinica Belgica Volume: 60 Issue: 2 Date: 2005 Pages: 63-69 DOI: 10.2143/ACB.60.2.2050444 Abstract : After notification of a case of fulminant hepatitis B virus (HBV) infection in a 83-year-old female resident of a nursing home to the Flemish Health Inspectorate, a seroepidemiological study and a retrospective cohort study were conducted among the 94 residents and 47 nursing staff to assess the extent of HBV transmission and to identify risk factors. Susceptible residents were vaccinated against HBV and their serological response to hepatitis B vaccination determined. From December 2002 to April 2003, five residents with acute hepatitis B infection were identified with an attack rate of 5.5% and a case fatality rate of 40%. Three other residents were identified as HBV surface antigen and e-antigen positive carrier. None of the nursing staff tested positive for acute HBV infection or HBV carriage. Diabetic patients who were exposed to a shared finger-stick device for blood sampling were 10.7 times more likely to contract an acute HBV infection (RR 10.7; 95% CI 1.3-91.3). Other potential risk factors were undergoing podiatric care and being exposed to the shared razor blade of the hairdresser. The transmission of the infection could be controlled by restricting the use of fingerstick capillary sampling devices to individual patients, assigning separate glucometers to individual patients and, implementation of standard infection-control recommendations like wearing gloves and performing hand hygiene by the nursing staff, assigning separate podiatric sets to individual patients. HBV vaccination of the residents with three doses of HBV vaccine has not induced a sufficient degree of protection. The outbreak stresses the need for appropriate and generally applied standard procedures in nursing homes to prevent bloodborne pathogens. |
