Care cascade of patients with hepatitis C and HIV identified by emergency department screening

Relationship of hepatitis C risk to hepatitis C test acceptance among adult patients participating in an ED hepatitis C screening programme

BACKGROUND

It is possible that adult ED patients consider their hepatitis C virus (HCV) risk factor history when deciding whether to accept HCV screening. To help address this question, we examined whether self-reporting any HCV risk was more common among ED patients who agreed than who declined HCV screening. Among ED patients who agreed to HCV screening, we also assessed if self-reporting any HCV risk was more common among those whose HCV antibody (Ab) and HCV viral load (VL) test results were positive.

METHODS

This study was conducted among adult patients ≥18 years old participating in a universal, ED-based HCV screening programme in New York City between 22 January 2019 and 9 April 2020. Participants were surveyed about their HCV risk factors. Differences in the frequencies of self-reporting any HCV risk were compared according to HCV screening acceptance and by HCV Ab and VL status.

RESULTS

Of the 4658 ED patients surveyed, 2846 (61%) accepted and 1812 (39%) declined HCV screening. Among these participants, 38% reported at least one HCV risk factor, most commonly injection drug use. Self-reporting any HCV risk was not more common among those who accepted versus declined HCV screening (40% vs 37%, p<0.7) but was more common among those with HCV Ab positive versus negative test results (36% vs 6%, p<0.001) and HCV VL positive versus negative results (95% vs 5%, p<0.001).

CONCLUSION

HCV risk factors were self-reported by more than one-third of ED patients but were not more commonly present among those who accepted HCV screening.

Models for Implementing Emergency Department-Initiated Buprenorphine With Referral for Ongoing Medication Treatment at Emergency Department Discharge in Diverse Academic Centers

There has been a substantial rise in the number of publications and training opportunities on the care and treatment of emergency department (ED) patients with opioid use disorder over the past several years. The American College of Emergency Physicians recently published recommendations for providing buprenorphine to patients with opioid use disorder, but barriers to implementing this clinical practice remain. We describe the models for implementing ED-initiated buprenorphine at 4 diverse urban, academic medical centers across the country as part of a federally funded effort termed "Project ED Health." These 4 sites successfully implemented unique ED-initiated buprenorphine programs as part of a comparison of implementation facilitation to traditional educational dissemination on the uptake of ED-initiated buprenorphine. Each site describes the elements central to the ED process, including screening, treatment initiation, referral, and follow-up, while harnessing organizational characteristics, including ED culture. Finally, we discuss common facilitators to program success, including information technology and electronic medical record integration, hospital-level support, strong connections with outpatient partners, and quality improvement processes.

Association of Referral Source and Substance Use with Hepatitis C Virus Outcomes at a Southern Academic Medical Center

OBJECTIVES

Therapeutic advances make the cure of chronic hepatitis C virus (HCV) infection achievable for individuals aware of their diagnosis who can access care. Identifying barriers to accessing care is critical to achieve population-level HCV elimination and improve the cascade of care from diagnosis to cure.

METHODS

To identify barriers to HCV care, we performed a retrospective observational analysis of outcomes for patients with chronic HCV referred to an infectious diseases clinic at an academic medical center in Charleston, South Carolina between January 1, 2015 and January 1, 2020. We categorized outcomes in the cascade of care between "never presenting for evaluation" and "completed treatment with documented cure." Patient demographic factors, referral source, ZIP code of residence, insurance status, clinical characteristics, antiviral regimen, psychiatric and substance use history, and route of infection were assessed for associations with care outcomes.

RESULTS

Of 407 referrals, 32% of patients never presented for an initial evaluation, an outcome that was associated with active substance use, mental health disease, and referral from an emergency department or obstetrics-gynecology provider. Of the patients who presented for an initial evaluation, 78% of patients initiated treatment. Active substance use was the only variable associated with lack of therapy initiation after presenting for an initial evaluation (odds ratio 2.5, 95% confidence interval 1.07-5.84). Once treatment had been initiated, no clinical or demographic variables were associated with odds of achieving documented or presumed HCV cure.

CONCLUSIONS

Active substance use, mental health disease, and referral from an emergency department or obstetrics-gynecology provider were associated with a lower odds of presenting for evaluation and initiation of HCV treatment. Innovative models to improve access to care and increase outreach to vulnerable populations will be essential to eliminate HCV.
