Background The Centers for Disease Control and Prevention (CDC) recommends one-time hepatitis C virus (HCV) antibody testing for “Birth Cohort” adults born during 1945–1965. Objective To examine the impact of an electronic health record (EHR)-embedded best practice alert (BPA) for HCV testing among Birth Cohort adults. Design Cluster-randomized trial was conducted from April 29, 2013 to March 29, 2014. Subjects and Setting Ten community and hospital-based primary care practices. Participants were attending physicians and medical residents during 25,620 study-eligible visits. Intervention Physicians in all practices received a brief introduction to the CDC testing recommendations. At visits for eligible patients at intervention sites, physicians received a BPA through the EHR to order HCV testing or medical assistants were prompted to post a testing order for the physician. Physicians in control sites did not receive the BPA. Main Outcomes HCV testing; the incidence of HCV antibody positive tests was a secondary outcome. Results Testing rates were greater among Birth Cohort patients in intervention sites (20.2% vs. 1.8%, P < 0.0001) and the odds of testing were greater in intervention sites after controlling for imbalances of patient and visit characteristics between comparison groups [odds ratio (OR), 9.0; 95% confidence interval, 7.6–10.7). The adjusted OR of identifying HCV antibody positive patients was also greater in intervention sites (OR, 2.1; 95% confidence interval, 1.3–11.2). Conclusions An EHR-embedded BPA markedly increased HCV testing among Birth Cohort patients, but the majority of eligible patients did not receive testing indicating a need for more effective methods to promote uptake.

Background From December 2012-March 2014, three randomized trials, each implementing a unique intervention in primary care settings (mail recruitment [repeated-mailing], an electronic health record best practice alert [BPA], and patient-solicitation [patient-solicitation]), evaluated HCV antibody testing, diagnosis, and costs for each of the interventions compared to standard-of-care testing. Multilevel multivariable models were used to estimate the adjusted risk ratio (aRR) for receiving an HCV antibody test, and costs were estimated using activity-based costing. Rationale To estimate the effects of interventions conducted as part of the Birth-cohort Evaluation to Advance Screening and Testing for Hepatitis C study on hepatitis C virus (HCV) testing and costs among persons of the 1945–1965 birth-cohort (BC). Main Results Intervention resulted in substantially higher HCV testing rates compared to standard-of-care (26.9% vs. 1.4% for repeated-mailing, 30.9% vs. 3.6% for BPA, and 63.5% vs. 2.0% for patient-solicitation), and significantly higher aRR for testing after controlling for sex, birth year, race, insurance type, and median household income (19.2 [95% Confidence Interval (CI) 9.7–38.2] for repeated-mailing, 13.2 [95% CI 3.6–48.6] for BPA, and 32.9 [95% CI 19.3–56.1] for patient-solicitation). The BPA intervention had the lowest incremental cost per completed test ($24 with fixed startup costs, $3 without) and also the lowest incremental cost per new case identified after omitting fixed startup costs ($1,691). Conclusion HCV testing interventions resulted in an increase in BC testing compared to standard-of-care but also increased costs. The effect size and incremental costs of BPA intervention (excluding startup costs) support more widespread adoption compared to the other interventions.

BC testing was effective in identifying previously undiagnosed HCV infections in primary care settings. (Hepatology 2017).

Objectives Vulnerable, urban populations with a history of substance use disorders have a high prevalence of hepatitis C virus (HCV). Primary care-based treatment has been proposed to improve access to care. In this study, we present outcomes from our urban, primary care-based HCV treatment program in patients treated with telaprevir or boceprevir in combination with pegylated-interferon and ribavirin (‘‘triple therapy’’). Methods We collected data from 126 consecutive patients with genotype 1 HCV monoinfection seen in our treatment program (2011–2013). Among the 40 who initiated treatment, we analyzed factors associated with achieving a sustained viral response (SVR). Results During the study period, 40 patients initiated triple therapy (32%), 80% with recent or past substance use disorders. Patients initiating treatment were younger than untreated patients (P = 0.002), but otherwise did not differ demographically, or in the severity of their liver fibrosis (P >0.05). An SVR was achieved in 18 patients (45%) and was less likely in patients with recent or past substance use disorders or psychiatric illness (both P <0.01). Conclusions Nearly one third of patients initiated triple therapy with SVR rates comparable to other HCV treatment settings, despite a significant burden of mental illness and substance dependence. Our experience demonstrates that a primary care-based practice can successfully deliver HCV care to a vulnerable population. Additional interventions may be needed to improve outcomes in patients with recent or past substance use disorders or psychiatric illness.

Hepatitis C virus infection affects approximately 2.2 to 3.2 million Americans. In 2012, the Centers for Disease Control and Prevention recommended a one-time antibody test of all persons belonging to the 1945–1965 birth cohort. Efforts to implement this recommendation in clinical settings are in their infancy; this case study report therefore seeks to share the experiences of three sites that implemented interventions to increase birth-cohort testing through participation in the Birth-cohort Evaluation to Advance Screening and Testing for Hepatitis C. At each site, project managers completed standardized questionnaires about their implementation experiences, and a qualitative analysis was conducted of the responses. The testing interventions used in-person recruitment, mail recruitment, and an electronic health record prompt. Sites reported that early efforts to obtain stakeholder buy-in were critical to effectively implement and sustain interventions and that the intervention required additional staffing resources beyond those being used for risk-based testing. In each case, administrative barriers were more extensive than anticipated. For the electronic health record–based intervention, technological support was critical in achieving study goals. Despite these barriers, interventions in all sites were successful in increasing rates of testing and case identification, although future studies will need to evaluate the relative costs and benefits of each intervention.
