27. Hepatitis B Virus Screening and Vaccination in Patients with HIV: A Survey of Physicians’ Current Clinical Practices

Abstract

BackgroundHepatitis B virus (HBV) and HIV co-infection is associated with high morbidity and mortality, but data and guidelines vary in terms of the best vaccination, re-vaccination, and monitoring practices. The purpose of this study was to evaluate the current HBV monitoring and vaccination practices of physicians who care for patients living with HIV.MethodsA Web-based survey was distributed to the University of California San Diego (UCSD) Infectious Diseases division via the UCSD ID listserv, Infectious Disease Society of America (IDSA) members via the IDea Exchange listserv, and to ID and HIV social network members via Twitter and Facebook. The survey consisted of demographic questions followed by two sets of case-based questions. The case questions focused on type, timing, and dosage of HBV vaccination administration among people living with HIV, HBV monitoring post-vaccination, and clinical approach to patients with isolated hepatitis B core antibody.ResultsA total of 67 clinicians from 24 states completed the survey (Table 1). Most (55%) provide care for more than 20 patients living with HIV per month. The majority of participants (82%) would not defer HBV vaccination until HIV virologic suppression. Almost half of participants (43%) indicated they would use Heplisav-B over older HBV vaccine formulations (Energix-B or Recombivax-HB) for initial vaccination of susceptible patients. The majority (88%) would repeat a vaccination series if the patient does not seroconvert; 23% would repeat with a standard dose series of Energix-B or Recombivax-HB, 24% with a double dose series of Energix-B or Recombivax-HB, and 45% would repeat with Heplisav-B. Approach to management of a patient living with HIV with isolated hepatitis B core antibody was varied. The majority would check a HBV DNA level (42%), while 25% would initiate a vaccination series and 24% would not pursue further intervention (Table 2).Table 1: Clinician Demographics Table 2: HBV Vaccination Practices of Physicians Caring for People Living with HIV ConclusionThis study provides insight into current HBV vaccination and monitoring practices of physicians who care for patients with HIV. The results revealed varied practice preferences and opportunities for improvement through standardization. Additional research is needed to elucidate the impact these various practices have on patient outcomes and healthcare expenditure.Disclosures All Authors: No reported disclosures
