Testing for hepatitis B virus alone does not increase vaccine coverage in non-immunized persons.

ABSTRACT: To determine whether hepatitis B virus (HBV)-testing could serve as a gateway to vaccinate non-immunized individuals in a low-prevalent country.Non-immunized subjects participating in a multi-center, HBV-testing campaign in Paris, France were identified and contacted via telephone 3-9 mo after testing in order to determine vaccination status. Vaccination coverage was evaluated in per-protocol (for all respondents) and intent-to-treat analysis (assuming all non-responders did not vaccinate).In total, 1215/4924 (24.7%) enrolled subjects with complete HBV serology were identified as non-immunized and eligible for analysis. There were 99/902 successfully contacted subjects who had initiated HBV vaccination after screening: per-protocol, 11.0% (95%CI: 9.0-13.2); intent-to-treat, 8.2% (95%CI: 6.7-9.8). In multivariable analysis, vaccination was more likely to be initiated in individuals originating from moderate or high HBV-endemic countries (P < 0.001), patients with limited healthcare coverage (P = 0.01) and men who have sex with men (P = 0.02). When asked about the reasons for not initiating HBV vaccination, the most frequent response was "will be vaccinated later" (33.4%), followed by "did not want to vaccinate" (29.8%), and "vaccination was not proposed by the physician" (21.5%). Sub-group analysis indicated a stark contrast in vaccination coverage across centers, ranging from 0%-56%.HBV-vaccination after HBV screening was very low in this study, which appeared largely attributed to physician-patient motivation towards vaccination. Increased vaccination coverage might be achieved by emphasizing its need at the organizational level.

Project description:The Centers for Disease Control and Prevention and US Preventive Services Task Force recommend one-time hepatitis C virus (HCV) testing for persons born during 1945-1965 (birth cohort). However, few studies estimate the effect of birth cohort (BC) testing implementation on HCV diagnoses in primary care settings. We aimed to determine the probability of identifying HCV infections in primary care using targeted BC testing compared with usual care at three academic medical centers. From December 2012 to March 2014, each center compared one of three distinct interventions with usual care using an independently designed randomized controlled trial. Across centers, BC patients with no clinical documentation of previous HCV testing or diagnosis were randomly assigned to receive a one-time offering of HCV antibody (anti-HCV) testing via one of three independent implementation strategies (repeated-mailing outreach, electronic medical record-integrated provider best practice alert [BPA], and direct patient solicitation) or assigned to receive usual care. We estimated model-adjusted risk ratios (aRR) of anti-HCV-positive (anti-HCV+) identification using BC testing versus usual care. In the repeated mailing trial, 8992 patients (intervention, n = 2993; control, n = 5999) were included in the analysis. The intervention was eight times as likely to identify anti-HCV+ patients compared with controls (aRR, 8.0; 95% confidence interval [CI], 2.8-23.0; adjusted probabilities: intervention, 0.27%; control, 0.03%). In the BPA trial, data from 14,475 patients (BC, n = 8928; control, n = 5,547) were analyzed. The intervention was 2.6 times as likely to identify anti-HCV+ patients versus controls (aRR, 2.6; 95% CI, 1.1-6.4; adjusted probabilities: intervention, 0.29%; control, 0.11%). In the patient-solicitation trial, 8873 patients (BC, n = 4307; control, n = 4566) were analyzed. The intervention was five times as likely to identify anti-HCV+ patients compared with controls (aRR, 5.3; 95% CI, 2.3-12.3; adjusted probabilities: intervention, 0.68%; control, 0.11%). Conclusion: BC testing was effective in identifying previously undiagnosed HCV infections in primary care settings. (Hepatology 2018;67:524-533).
