Postpartum Hepatitis C Linkage to Care Program in a Co-located Substance Use Disorders Treatment Model.

PURPOSE

Hepatitis C virus (HCV) is increasingly prevalent in pregnancy and among people with substance use disorders (SUD). Highly effective treatments are now available for chronic HCV. Qualifying for HCV treatment often requires preauthorization and several clinical criteria, including laboratory assessment of liver function and other infectious diseases and liver imaging to assess for fibrosis. Linkage to care (LTC) models have been shown to assist with obtaining the necessary clinical information (laboratory assessment/liver imaging) and improving HCV treatment rates in non-pregnant individuals.

DESCRIPTION

Beginning in December 2020, a specialized LTC team identified patients with HCV viremia who were interested in postpartum treatment. The LTC team assisted patients with completing the necessary clinical criteria (laboratory assessment and liver imaging) for HCV treatment. Patients were then linked to infectious disease specialists who prescribed treatment to patients via telemedicine. Most patients identified with HCV were enrolled in our institution's co-located obstetric and SUD program, which provides continued care until 1 year postpartum.

ASSESSMENT

In 2019, an internal review identified that none of the 26 pregnant patients with HCV viremia in our co-located obstetric and SUD program were prescribed direct-acting antiviral (DAA) treatment within 12 months postpartum. Between December 2020 and July 2022, our HCV LTC team identified 34 patients with HCV who were eligible for treatment. Of these patients, 55% (19/34) obtained all necessary laboratory and liver imaging requirements and 79% (15/19) were prescribed DAA treatment after a telehealth visit with an infectious disease specialist. All fifteen patients who were prescribed treatment participated in the co-located obstetric and SUD program. The largest barrier to obtaining treatment was completing the necessary laboratory and liver imaging requirements for prescribing DAA. Only one patient who did not receive care in our co-located obstetric and SUD program had completed the necessary laboratory and liver imaging requirements to proceed with treatment but did not follow up with the infectious disease specialist for DAA treatment.

CONCLUSION

Our HCV LTC program was successful in treating postpartum patients for HCV if they participated in the co-located obstetric and SUD program at our institution. Creating a partnership with an infectious disease specialist and utilizing telemedicine were beneficial strategies to connect patients to treatment for HCV during the postpartum period.
