INTRODUCTION: Hepatitis B virus (hbv) reactivation is a recognized complication of chemotherapy. The U.S. Centers for Disease Control and Prevention recommend that all patients be screened for the hbv surface antigen (hbsag) before chemotherapy. We sought to determine the frequency of hbsag testing before chemotherapy at our hospital and to increase the frequency of testing to more than 90% of patients starting chemotherapy. METHODS: Using a retrospective electronic chart review, we identified the frequency of hbsag testing for patients initiated on intravenous chemotherapy at out institution between March 2006 and March 2007. The frequency of left ventricular function testing in the subgroup of patients receiving potentially cardiotoxic chemotherapy was identified as a comparator. An educational intervention was developed and delivered to the multidisciplinary oncology team. The frequency of hbsag testing was determined post intervention. Qualitative interviews were conducted with the members of the oncology team to identify risk perception and barriers to testing. RESULTS: Of 208 patients started on intravenous chemotherapy between March 2006 and March 2007, only 28 (14%) were tested for hbsag. All 138 patients scheduled for cardiotoxic chemotherapy (100%) underwent left ventricular function testing. In the post-intervention phase, of 74 patients started on intravenous chemotherapy, 24 (31%) underwent hbsag testing, with 1 patient testing positive. CONCLUSIONS: The frequency of testing for hbsag before chemotherapy was very low at our institution. An educational intervention resulted in only a modest improvement. Potential barriers to routine screening include lack of awareness about existing guidelines, controversy about the evidence that supports hbsag testing guidelines, and a perception by physicians that hbv reactivation does not occur with solid tumours.
