Individuals born between 1945–1965 represent 81% of all persons chronically infected with hepatitis C virus (HCV) in the USA and are largely unaware of their positive status. The baseline HCV screening rate in this population in an academic internal medicine clinic at a US hospital was less than 3.0%. The goal was to increase the rate of HCV screening in patients born between 1945 and 1965 to 20% within 24 months. The quality improvement team used the Plan Do Study Act Model. Outcome measures included HCV antibody screening, HCV RNA positive rate and linkage to hepatology care. Process measures included HCV antibody order and completion rates. The quality improvement team performed a root cause analysis and identified barriers for HCV screening and linkage to care. The key elements of interventions included redesigning nursing workflow, use of health information technology and educating patients, physicians and nursing staff about HCV. The HCV screening rate was 30.3% (391/1291) within 24 months. The HCV antibody positive rate was 43.5% (170/391), and HCV RNA positive rate was 95.3% (162/170). HCV infection was diagnosed in 12.5% (162/1291) of patients or 41.4% (162/391) of the screened population. Of those positive, 70% (114/162) were linked to hepatology care within the 24-month project timeframe. Eighty percent of patients seen by a hepatologist were treated with direct-acting antivirals agents. The HCV screening rate was sustained at 25.4% during the post-project 1-year period. Engagement of a multidisciplinary team and education to patients, physicians and nursing staff were the key drivers for success.

Hepatitis C virus (HCV) infection can induce insulin resistance, and patients with diabetes mellitus (DM) have a higher prevalence of HCV infection. Patient outcomes improve after HCV eradication in DM patients. However, HCV micro-elimination targeting this population has not been approached. Little is known about using electronic alert systems for HCV screening among patients with DM in a hospital-based setting. We implemented an electronic reminder system for HCV antibody screening and RNA testing in outpatient departments among patients with DM. The screening rates and treatment rates at different departments before and after system implementation were compared. The results indicated that the total HCV screening rate increased from 49.3% (9505/19,272) to 78.2% (15,073/19,272), and the HCV-RNA testing rate increased from 73.4% to 94.2%. The anti-HCV antibody seropositive rate was 5.7%, and the HCV viremia rate was 62.7% in our patient population. The rate of positive anti-HCV antibodies and HCV viremia increased with patient age. This study demonstrates the feasibility and usefulness of an electronic alert system for HCV screening and treatment among DM patients in a hospital-based setting.

Abstract Background Despite hepatitis C virus (HCV) age cohort and risk factor screening recommendations, many at-risk individuals remain undiagnosed. Current screening practices may not adequately capture those at high risk for infection, especially in regions with increasing injection drug use (IDU). Universal HCV screening in a Tennessee tertiary care emergency department (ED) was introduced to help define regional epidemiology and to improve diagnosis and linkage to care. Methods This screening program was implemented in the Vanderbilt University Medical Center ED. Adult patients who underwent phlebotomy for clinical purposes were offered HCV screening. Samples were initially tested for HCV antibodies; if positive, samples were reflexed for HCV RNA testing. Patients with positive HCV RNA tests (i.e., active HCV infection) were notified, counseled, and offered linkage to care. Results A total of 11,637 screening tests were performed between April 1, 2017 and March 31, 2018, with 1,008 (8.7%) HCV antibody positive and 488 (4.2%) RNA positive. Of note, 81 (0.7%) were HCV antibody positive but RNA testing could not be performed due to insufficient sample volume. Several notable populations had high rates of HCV (Table 1). Importantly, 3.9% of people not born between 1945 and 1965 were HCV RNA positive, and they were the majority (63.5%) of patients with active HCV (Table 2). A minority (31.6%) of those with active HCV had a known history of IDU (Table 2). Conclusion HCV is common among patients presenting for emergency care at a Tennessee tertiary care ED. Universal screening identified many infections that would have been missed using age cohort and risk factors alone. ED HCV screening may be a useful method to augment guideline-based testing and intervene among populations not consistently screened. Disclosures C. A.

Abstract Background We implemented and evaluated a large health system-wide hepatitis C virus (HCV) screening and linkage to care program for persons born between 1945 and 1965 (“baby boomers”). Methods An electronic health record (EHR) clinical decision support (CDS) tool for HCV screening for baby boomers was introduced in August 2015 for patients seen in the outpatient University of California, Los Angeles healthcare system setting. An HCV care coordinator was introduced in January 2016 to facilitate linkage to HCV care. We compared HCV testing in the year prior (August 2014–July 2015) to the year after (August 2015–July 2016) implementation of the CDS tool. Among patients with reactive HCV antibody testing, we compared outcomes related to the care cascade including HCV ribonucleic acid (RNA) testing, HCV RNA positivity, and linkage to HCV specialty care. Results During the study period, 19606 participants were screened for HCV antibody. Hepatitis C virus antibody screening increased 145% (from 5676 patients tested to 13930 tested) after introduction of the CDS intervention. Screening increased across all demographic groups including age, sex, and race/ethnicity, with the greatest increases among those in the older age groups. The addition of an HCV care coordinator increased follow-up HCV RNA testing for HCV antibody positive patients from 83% to 95%. Ninety-four percent of HCV RNA positive patients were linked to care postimplementation. Conclusions Introduction of an EHR CDS tool and care coordination markedly increased the number of baby boomers screened for HCV, rates of follow-up HCV RNA testing, and linkage to specialty HCV care for patients with chronic HCV infection.

Abstract Background Recent data on the evaluation of screening serological assays on anti-HCV among a large sample of blood donors is lacking. The present study aimed to perform a multicenter evaluation of EIAs and CLIAs for detection of anti-HCV among blood donors in 16 different Chinese blood centers/banks. Methods A total of 1,309 samples containing 582 anti-HCV screening negatives and 727 positives collected from 15 blood centers/banks all over China. A total of 10 different anti-HCV assays (8 EIAs and 2 CLIAs) were evaluated in 16 different blood centers/banks. Confirmatory testing was performed using RIBA and HCV RNA tests. Results There were 963 true negatives, 261 positives, and 85 indeterminate samples. False positive rate of screening testing was 52.54% (382/727). Roche and InTec had the highest sensitivity (98.47%) and KHB and Wantai (indirect EIA) had the highest specificity (99.23%). Ortho/Abbott together with InTec could detect all the true positives. RIBA indeterminate samples showed quite different S/CO ratios detected by Roche compared with RIBA positives (4.84 vs 19.36, P < 0.0001), and higher S/CO ratios than RIBA negatives (4.84 vs 2.94, P = 0.020). However, there was no difference among the three groups when detected by Abbott. Also, the antigen distribution and band intensity were different between indeterminate and RIBA positive. When S/CO ratio went to 8.2 on Roche and 4.2 on Abbott, the PPV could achieve more than 95%. Conclusion False reactive problem of anti-HCV screening should be solved urgently. RIBA indeterminate donations may be a special group, should be further studied.

Abstract Background Hepatitis C virus (HCV) infects 4.1 million people in the United States, of whom 50% are unaware of their status. In 2016, Pennsylvania introduced a law mandating HCV screening for patients born between 1945-1965 in inpatient settings. However, HCV screening during hospital admissions has remained low in part due to limited knowledge on HCV testing requirements, interpretation of results, and treatment approaches. To overcome these barriers, we implemented a quality improvement initiative to automate HCV screening as part of hospital admission order sets, facilitate linkage to HCV treatment, and sought to evaluate its effectiveness. Methods Between September 2020 and May 2021, the automated inpatient HCV screening strategy was implemented at a single 328-bed academic hospital in Philadelphia, PA. Patients born between 1945-1965 without documentation of HCV screening or diagnosis in the electronic medical record had a HCV antibody with reflexive confirmatory RNA assay automatically populated in the admission order set. Admitting providers could opt out of the screening as appropriate. All patients with reactive HCV antibody were approached by the Hepatitis Linkage Team for result disclosure, counseling, and linkage to treatment for those with HCV viremia. Cascade of care was detailed for those linked to providers within the health system. Results During the initial 8 months of the program, 2,203 patients were screened for HCV, identifying 156 with reactive HCV antibody (7.1% seroprevalence). Among 147 with completed HCV RNA assay, 51 were viremic (34.7%). Fourteen viremic patients were not linked to care, including six with a terminal illness, two who declined linkage, and six who did not respond to linkage attempts. Nine were linked to care at other health systems. Among the 28 patients linked to providers in the health system, 50% completed initial visits, 42.8% were prescribed direct acting antivirals (DAA), and 21.4% completed therapy by May 2021. One person achieved sustained virologic response 12 weeks after treatment as of May 2021 (Figure 1). Figure 1. Cascade of HCV Care Among Patients Screened During Hospital Admission from September 2020 to May 2021 Conclusion Automated inpatient HCV screening is a viable strategy to identify people with HCV and facilitate linkage to care. Optimal strategies to ensure patients access and maintain care require further study. Disclosures All Authors: No reported disclosures

SUMMARYAn unlinked anonymous study was conducted to estimate the prevalence of hepatitis C virus (HCV) infection in emergency department (ED) attendees at a London Hospital. Nine hundred and ninety-seven samples collected over a 12-day period were tested for HCV antibody (Ab) and reactive samples were further tested for HCV RNA. The HCV seroprevalence was 2·6% (26/997) with 1·2% (12/997) HCV RNA positive. A peak HCV RNA-positive prevalence of 4·8% (3/63) was found in males aged 35–44 years, this was compared to 0% (0/136) in males aged <35 years (P = 0·0614) and 1·4% (4/278) in males aged ⩾45 years (P = 0·2415). Assuming the cost for HCV Ab is £6 and HCV RNA is £40 per test, screening ED attendees aged 25–54 years would cost £360 per viraemic infection and identify 82% of those who were HCV RNA positive, yielding the most favourable cost/benefit ratio. HCV screening of ED attendees aged 25–54 years in this population could be an effective way of identifying patients and limit onward transmission.

Abstract Background Incarcerated persons are a special population with higher hepatitis C virus (HCV) prevalence and should be prioritized for micro-elimination. This study aimed to investigate the seroprevalence and to evaluate the effectiveness and safety of direct acting antiviral (DAA) therapy in the custodial settings. Methods Incarcerated persons in Yunlin Prison were recruited to receive anti-HCV antibody screening. Patients with positive HCV ribonucleic acid (HCV RNA) were treated with glecaprevir/pibrentasvir (GLE/PIB) in our special chronic hepatitis C (CHC) clinic in prison. The primary endpoint was sustained virologic response at week 12 off therapy (SVR12). Results A total of 1402 incarcerated persons were invited to anti-HCV screening and 824 (58.7%) accepted. The prevalence of anti-HCV positivity was 33.5% (276/824) and the viremic rate (detectable HCV RNA) was 69.2% (191/276). According to FIB-4 index, patients with F3 stage were six (3.1%), but none met the criteria of F4 stage. However, six (3.1%) had liver cirrhosis with splenomegaly, confirmed by findings of ultrasonography. The median log10 HCV RNA level at baseline was 6.235 (2.394-7.403). Genotype (GT) 6 was predominant (39.3%), followed by GT 1a (22.0%) and 1b (14.1%). Mixed genotype HCV infection accounted for 3.6% of total infections. In total, 165 patients received GLE/PIB therapy. The overall SVR12 rates were 100%. Conclusions DAA therapy is highly effective and safe for incarcerated patients in Taiwan. Our special prison-based CHC clinic, linking universal screening to medical care, can serve as a model for micro-elimination of HCV in custodial settings.

Abstract Background: Antibodies to hepatitis C virus (anti-HCV) have typically been detected by enzyme immunoassay (EIA). A chemiluminescence assay (CA) for anti-HCV is now commercially available. Methods: We compared the positive rate for a CA in a HCV screening program for veterans with historical rates obtained with EIA. We also compared results in 2824 samples tested by both methods and assessed the significance of low signal-to-cutoff (S/C) ratios. Results: The frequency of CA-positive results was significantly lower than with EIA (12.6% vs 16.0%; P &lt;0.0001). The frequency of low S/C ratios was also significantly lower with CA (11.5% vs 20.0%; P &lt;0.0001). Among low-positive values, samples positive by CA were significantly less likely to be recombinant immunoblot assay (RIBA)-negative (64% vs 84%; P &lt;0.0005). In parallel testing, results for 111 samples (3.9%) were discrepant between the two assays; all but 6 had low S/C ratios, and confirmatory testing was performed on all but 8 samples. Of 56 EIA-positive, CA-negative samples tested by RIBA, only 1 was positive. Of 24 CA-positive, EIA-negative samples, 62% were RIBA-negative. Using a negative RIBA result as an indication of false-positive anti-HCV results, the positive predictive value of EIA was 93% compared with 98% with CA. HCV RNA was positive in 90% of samples high-positive by both CA and EIA. Only 2 of 30 (7%) low-positive CA samples were RNA-positive. Conclusions: CA produces fewer false-positive and fewer low-positive results that require confirmatory RIBA testing. The S/C ratio remains useful for characterizing positive results.

Hepatitis C (HCV) infection could be spread by blood transfusion. Screening of HCV in donor blood could prevent HCV infection to the recipient. HCV antibody test using rapid test of multiple antibody detection by immunochromatography method is an easy and rapid test that could detect four HCV antibodies separately. The aim of this study was to evaluate the diagnostic value of antibody HCV using multiple antibody detection rapid test in diagnosing HCV infection. This was an analytical observational study with a cross sectional design. The samples consisted of 42 donors’ blood serum from the Surabaya Branch of the Indonesian Red Cross which underwent HCV infection test using ELISA method. The samples were then tested using PCR HCV RNA as the gold standard and antibody HCV multiple antibodydetection rapid test The diagnostic value of HCV antibody test using multiple antibody detection rapid test by immunochromatography method showed a diagnostic sensitivity of 100%, diagnostic specificity of 75%, positive predictive value of 66.7% and negative predictive value of 100%, a diagnostic efficiency of 83.3%, with a positive probability ratio of 4 times. The most often positive antibody pattern was four (4) positive antibodies (core protein, NS3, NS4 and NS5). Core protein (CP) and NS3 were the most often positive antibodies. Based on this study result, the HCV antibody test using multiple antibody detection rapid test by immunochromatography method has a good diagnostic value.

Abstract Background Between December 2018 and January of 2019, we evaluated the accuracy of the point-of-care Hepatitis C (HCV) antibody test (POC; OraQuick HCV) used at a community-based needle and syringe exchange program serving persons who inject drugs in Tallinn, Estonia. Methods We compared the results of screening for HCV antibodies by OraQuick (oral swab) and enzyme immunoassay (EIA; blood draw) and assessed test results implications in a high prevalence setting. Findings Of the 100 participants, 88 (88%) had reactive POC test results, and 93 were HCV antibody positive on EIA testing. Sensitivity, specificity and negative predictive value (NPV) for the POC assay with EIA as the relevant reference test were as follows: 94.6% (95% CI 90.0–99.2%), 100% and 58.3% (95% CI 30.4–86.2%). Of the 12 testing, HCV-negative with the POC only 7 (58.3%) were true negatives. Conclusions Oral swab rapid testing HCV screening in this nonclinical setting was sensitive and specific but had unacceptably low NPV. In high prevalence settings, POC tests with high sensitivity and that directly measure HCV RNA may be warranted.
