Hepatitis C virus screening at a Veterans Administration Hospital in New York City

Abstract

Asymptomatic hepatitis C virus (HCV) infection has the highest prevalence in "baby boomers" born in 1945 through 1965. New York State mandates that all persons born during this period be screened at least once for hepatitis C. Military veteran HCV screening is often missed during primary care visits. After baseline screening, provider education with and without an HCV education dashboard of information in the Electronic Medical Record system was used to determine if screening proportions could be improved. The Chi-square and Z-test for independent proportions compared after with before education screening. The odds ratio compared after versus before screening odds. Two interventions were tested. One was provider education with a 30-minute lecture. The second was the lecture with addition of an HCV education computer dashboard. The Chi-square test and Z-test comparing the month immediately after provider education was significant for increased screening (p < .01) compared with baseline. There was a 2.04-fold (95% confidence interval, 1.31-3.20) greater odds of screening in the month after education. If two or more months went by after education, the effect of education no longer improved screening proportions. Provider education plus the use of HCV education dashboard did not improve screening from baseline to the month immediately after screening (p = .95). Provider education significantly improved HCV screening the month immediately after education, then regressed toward baseline. Adding an HCV education dashboard to education did not improve screening. To maintain elevated screening proportions, provider screening education must be reinforced on a frequent basis for sustained effect.
