ABSTRACT
Background and Aims: Approximately half of adults with hepatitis C in the United States do not know their infection status, and the majority of persons who know they are positive for hepatitis C virus (HCV) antibodies fail to receive care. We conducted a screening program in retail pharmacies and calculated the percentages of anti-HCV-positive individuals and how many subsequently entered a pathway to care. Methods: At 45 Walgreens retail pharmacies in 9 US cities, direct store advertising was used to recruit individuals for HCV antibody testing. Participants were at least 18 years old with at least 1 HCV risk factor, such as being born between 1945 and 1965. One day per week at each site, a phlebotomist obtained consent from interested participants and performed the testing. Within 3 business days, an HCV management specialist contacted anti-HCV-positive individuals and provided test results and a pathway for obtaining HCV RNA testing. During the following 21 to 28 days, the same HCV management specialist telephoned individuals to determine whether they underwent an HCV RNA test. Results: Between September 2015 and February 2016, 1298 individuals consented. Two patients withdrew consent after testing. In all, 8% (103/1296) were HCV antibody-positive; of them, 91 (88%) were contacted by an HCV management specialist. During the 21- to 28-day follow-up, 56 individuals (62%; 56/91) were reached by an HCV management specialist, and 29 (52%; 29/56) confirmed that an HCV RNA test was ordered. Conclusions: These results provide evidence in support of point-of-care HCV screening in retail pharmacies for at-risk individuals in the United States.
ABSTRACT
BACKGROUND: Estimates suggest that only 20 % of HCV-infected patients have been identified and <10 % treated. However, baby boomers (1945-1965) are identified as having a higher prevalence of HCV which has led the Centers for Disease Control and Prevention to make screening recommendations. The aim of this study was to implement the CDC's screening recommendations in the unique setting of gastroenterology practices in patients previously unscreened for HCV. METHODS: After obtaining patient informed consent, demographics, clinical and health-related quality of life (HRQOL) data were collected. A blood sample was screened for HCV antibody (HCV AB) using the OraQuick HCV Rapid Antibody Test. HCV AB-positive patients were tested for presence of HCV RNA and, if HCV RNA positive, patients underwent treatment discussions. RESULTS: We screened 2,000 individuals in 5 gastroenterology centers located close to large metropolitan areas on the East Coast (3 Northeast, 1 Mid-Atlantic and 1 Southeast). Of the screened population, 10 individuals (0.5 %) were HCV AB-positive. HCV RNA testing was performed in 90 % (9/10) of HCV AB-positive individuals. Of those, 44.4 % (4/9) were HCV RNA-positive, and all 4 (100 %) were linked to caregiver. Compared to HCV AB negative subjects, HCV AB-positive individuals tended to be black (20.0 vs. 5.2 %, p = 0.09) and reported significantly higher rates of depression: 60.0 vs. 21.5 %, p = 0.009. These individuals also reported a significantly lower HRQOL citing having more fatigue, poorer concentration, and a decreased level of energy (p < 0.05). DISCUSSION: Although the prevalence of HCV AB-positive was low in previously unscreened subjects screened in the gastroenterology centers, the linkage to care was very high. The sample of patients used in this study may be biased, so further studies are needed to assess the effectiveness of the CDC screening recommendations. CONCLUSION: Implementation of the Baby Boomer Screening for HCV requires identifying screening environement with high prevalence of HCV+ individuals as well as an efficient process of linking them to care.
