The evaluation of homelessness on HCV treatment outcomes among current and former people who inject drugs

Abstract Background This initiative increased infectious disease (ID) screening in an adult medication assisted treatment (MAT) population at a Federally Qualified Health Center (FQHC) by implementing opt-out screening for HIV, viral hepatitis, and sexually transmitted infections (STIs), and assessed the success of a co-located hepatitis C (HCV) treatment program. Methods ID providers maintained a standing lab order for HIV, hepatitis A, hepatitis B, HCV, syphilis, chlamydia/gonorrhea (GC/CT), and trichomoniasis (trich), with reflex to confirmatory for HIV/HCV/syphilis. For all existing and new adult MAT patients, a MAT RN provided education, ensured lab draw on the day of MAT induction, and scheduled an ID follow-up visit. The patient then had an in-person or telemedicine visit with the ID provider to review results, discuss risk reduction, and initiate treatment (HIV PrEP or treatment for STI, HCV, or HIV) as indicated. Data was compiled and monitored by a Prevention RN. Plan, Do, Study, Act (PDSA) Model PDSA model demonstrating implementation approach Results The rate of testing among MAT patients increased over a one-year period. HCV treatment uptake in this setting exceeded that documented in published data for people who inject drugs (PWID). HCV Care Cascade Outcomes HCV screening and treatment outcomes within HCV Care Cascade model Screening Outcomes Screening rates among adult MAT population over a one-year measurement period Conclusion This study documents the successful implementation of an opt-out screening program among an adult substance use disorder (SUD) treatment population across urban, mixed, and designated rural environments. HCV treatment uptake in this setting exceeded that documented in published data for people who inject drugs (PWID). Barriers to implementation included acceptance among patients with long-term MAT participation, acceptance/adoption by behavioral health nursing and provider staff, and functional workflow development – establishment of protocol, lab availability, scheduling, and “tough sticks.” Modifications that increased effectiveness included an interdisciplinary approach and dedicated staff for monitoring results completion and patient outreach.

Abstract Background Cigarette smoking has emerged as a leading cause of mortality among people with hepatitis C virus (HCV). People who inject drugs (PWID) represent the largest group of adults infected with HCV in the US. However, cigarette smoking remains virtually unexplored among this population. This study aimed at (1) determining prevalence and correlates of cigarette smoking among HCV-infected PWID enrolled in opiate agonist treatment programs; (2) exploring the association of smoking with HCV treatment outcomes including adherence, treatment completion and sustained virologic response (SVR); and 3) exploring whether cigarette smoking decreased after HCV treatment. Methods Participants were 150 HCV-infected PWID enrolled in a randomized clinical trial primarily designed to test three intensive models of HCV care. Assessments included sociodemographics, presence of chronic health and psychiatric comorbidities, prior and current drug use, quality of life, and HCV treatment outcomes. Results The majority of the patients (84%) were current cigarette smokers at baseline. There was a high prevalence of psychiatric and medical comorbidities in the overall sample of PWID. Alcohol and cocaine use were identified as correlates of cigarette smoking. Smoking status did not influence HCV treatment outcomes including adherence, treatment completion and SVR. HCV treatment was not associated with decreased cigarette smoking. Conclusions The present study showed high prevalence of cigarette smoking among this population as well as identified correlates of smoking, namely alcohol and cocaine use. Cigarette smoking was not associated with HCV treatment outcomes. Given the detrimental effects that cigarette smoking and other co-occurring, substance use behaviors have on HCV-infected individuals’ health, it is imperative that clinicians treating HCV also target smoking, especially among PWID. The high prevalence of cigarette smoking among PWID will contribute to growing morbidity and mortality among this population even if cured of HCV. Tailored smoking cessation interventions for PWID along with HCV treatment may need to be put into clinical practice. Trial registration NCT01857245. Registered May 20, 2013.

Abstract Background Hepatitis C virus (HCV) frequently co-occurs with symptoms of depression, which are aggravated on interferon-based regimens. However, it is unknown whether HCV treatment with direct-acting antivirals (DAAs) has effects on depressive symptoms among people who inject drugs (PWID). In this study, we examined changes in depressive symptoms during and after HCV treatment among PWID on opioid agonist therapies (OATs). Methods Participants were 141 PWID who achieved sustained viral response after on-site HCV treatment at 3 OAT programs. Depressive symptoms were assessed using the Beck Depression Inventory–II (BDI-II) at baseline, every 4 weeks during treatment, and 12 and 24 weeks after treatment completion. Current diagnosis of depression or other psychiatric diagnoses were obtained through chart review. Use of illicit drugs was measured by urine toxicology screening. Alcohol use was measured using the Addiction Severity Index–Lite. Results Of the 141 PWID infected with HCV, 24.1% had severe, 9.9% had moderate, 15.6% had mild, and 50.4% had minimal levels of depression as per BDI-II scores at baseline. HCV treatment was significantly associated with reductions in depressive symptoms that persisted long term, regardless of symptom severity (P < .001) or presence of depression (P ≤ .01) or other psychiatric diagnoses (P ≤ .01) at baseline. Concurrent drug use (P ≤ .001) or hazardous alcohol drinking (P ≤ .001) did not interfere with reductions in depressive symptoms. Conclusions Depressive symptoms are highly prevalent among HCV-infected PWID. HCV treatment was associated with sustained reductions in depressive symptoms. HCV therapy with DAAs may have important implications for PWID that go beyond HCV cure.

Abstract Background. Hepatitis C virus (HCV) treatment access among human immunodeficiency virus (HIV)/HCV-coinfected people who inject drugs is poor, despite a high burden of disease in this population. Understanding barriers and facilitators to HCV treatment uptake is critical to the implementation of new direct-acting antivirals. Methods. We conducted in-depth interviews with patients, physicians, and social workers at an HIV treatment facility and methadone maintenance treatment centers in Guangzhou, China to identify barriers and facilitators to HCV treatment. We included patients who were in various stages of HCV treatment and those who were not treated. We used standard qualitative methods and organized data into themes. Results. Interview data from 29 patients, 8 physicians, and 3 social workers were analyzed. Facilitators and barriers were organized according to a modified Consolidated Framework for Implementation Research schematic. Facilitators included patient trust in physicians, hope for a cure, peer networks, and social support. Barriers included ongoing drug use, low HCV disease knowledge, fragmented reimbursement systems, HIV exceptionalism, and stigma. Conclusions. Expanding existing harm reduction programs, HIV treatment programs, and social services may facilitate scale-up of direct-acting antivirals globally. Improving integration of ancillary social and mental health services within existing HIV care systems may facilitate HCV treatment access.

Abstract Background People who inject drugs (PWID) experience barriers to accessing testing and treatment for hepatitis C virus (HCV) infection. Opioid agonist therapy (OAT) may provide an opportunity to improve access to HCV care. This systematic review assessed the association of OAT and HCV testing, treatment, and treatment outcomes among PWID. Methods Bibliographic databases and conference presentations were searched for studies assessing the association between OAT and HCV testing, treatment, and treatment outcomes [direct-acting antiviral (DAA) therapy only] among people who inject drugs (in the past year). Meta-analysis was used to pool estimates. Results Among 9,877 articles identified, 22 studies conducted in Australia, Europe, North America, and Thailand were eligible and included. Risk of bias was serious in 21 studies and moderate in one study. Current/recent OAT was associated with an increased odds of recent HCV antibody testing [4 studies; odds ratio (OR), 1.80; 95% CI:1.36, 2.39), HCV RNA testing among those who were HCV antibody positive (2 studies; OR, 1.83; 95% CI:1.27, 2.62), and DAA treatment uptake among those who were HCV RNA positive (7 studies; OR 1.53; 95% CI: 1.07, 2.20). There was insufficient evidence of an association between OAT and treatment completion (9 studies) or sustained virologic response following DAA therapy (9 studies). Conclusions Opioid agonist therapy can increase linkage to HCV care, including uptake of HCV testing and treatment among PWID. This supports the scale-up of OAT as part of strategies to enhance HCV treatment to further HCV elimination efforts.
