A cascade of care analysis on the elimination of hepatitis C from public hospitals in Madrid

Enhancing Hepatitis C Virus Testing, Linkage to Care, and Treatment Commencement in Hospitals: A Systematic Review and Meta-analysis

Background

The hospital-led interventions yielding the best hepatitis C virus (HCV) testing and treatment uptake are poorly understood.

Methods

We searched Medline, Embase, and Cochrane databases for studies assessing outcomes of hospital-led interventions for HCV antibody or RNA testing uptake, linkage to care, or direct-acting antiviral commencement compared with usual care, a historical comparator, or control group. We systematically reviewed hospital-led interventions delivered in inpatient units, outpatient clinics, or emergency departments. Random-effects meta-analysis estimated pooled odds ratios [pORs] measuring associations between interventions and outcomes. Subgroup analyses explored outcomes by intervention type.

Results

A total of 7872 abstracts were screened with 23 studies included. Twelve studies (222 868 participants) reported antibody testing uptake, 5 (n = 4987) reported RNA testing uptake, 7 (n = 3185) reported linkage to care, and 4 (n = 1344) reported treatment commencement. Hospital-led interventions were associated with increased antibody testing uptake (pOR, 5.83 [95% confidence interval {CI}, 2.49-13.61]; I 2 = 99.9%), RNA testing uptake (pOR, 10.65 [95% CI, 1.70-66.50]; I 2 = 97.9%), and linkage to care (pOR, 1.75 [95% CI, 1.10-2.79]; I 2 = 79.9%) when data were pooled and assessed against comparators. Automated opt-out testing (5 studies: pOR, 16.13 [95% CI, 3.35-77.66]), reflex RNA testing (4 studies: pOR, 25.04 [95% CI, 3.63-172.7]), and care coordination and financial incentives (4 studies: pOR, 2.73 [95% CI, 1.85-4.03]) showed the greatest increases in antibody and RNA testing uptake and linkage to care, respectively. No intervention increased uptake at all care cascade steps.

Conclusions

Automated antibody and reflex RNA testing increase HCV testing uptake in hospitals but have limited impact on linkage to treatment. Other interventions promoting linkage must be explored.

Telehealth to increase healthcare access; perspectives of people who use drugs

BACKGROUND

People who use drugs (PWUD) often face restricted healthcare access despite their heightened healthcare needs. Factors such as stigma, mistrust of the healthcare system, competing priorities, and geographical barriers pose significant healthcare access challenges. Telehealth offers an innovative solution to expand healthcare access for better inclusion of underserved populations in healthcare. We aimed to explore PWUDs' perceptions of telehealth as a healthcare delivery modality.

METHODS

We utilized purposive sampling to recruit participants (N = 57) for nine focus group discussions (FGDs) in Athens, Greece. Eligibility criteria required participants to be at least 18 years, with current or prior injection drug use, and current internet access. The FGDs followed a semi-structured interview guide, were audio recorded, transcribed verbatim, translated into English, and de-identified. We applied thematic analysis to analyze FGD transcripts.

RESULTS

Participants' mean (standard deviation) age was 47.9 (8.9) years, 89.5% (51/57) were male, 91.2% (52/57) were of Greek origin, and 61.4% (35/57) had attended at least 10 years of school. Three main themes emerged from the FGDs: (1) high internet utilization for healthcare-related purposes among PWUD, (2) highlighting telehealth benefits despite access obstacles and PWUDs' concerns about diagnostic accuracy, and (3) approaches to overcome access obstacles and build digital trust. Participants extensively used the internet for healthcare-related processes, such as accessing healthcare information and scheduling provider appointments. Despite being telehealth-inexperienced, most participants expressed a strong willingness to embrace telehealth due to its perceived convenience, time-saving nature, and trusted digital environment. Some participants recognized that the inability to conduct physical examinations through telehealth reduces its diagnostic accuracy, while others expressed concerns about digital literacy and technological infrastructure accessibility. Most participants expressed a preference for video-based telehealth encounters over audio-only encounters. To build trust in telehealth and promote patient-centeredness, participants recommended an initial in-person visit, virtual eye contact during telehealth encounters, patient education, and partnerships with PWUD-supportive community organizations equipped with appropriate infrastructure.

CONCLUSIONS

PWUD frequently use the internet for health-related purposes and suggested several approaches to enhance virtual trust. Their insights and suggestions are practical guidance for policymakers seeking to enhance healthcare access for underserved populations through telehealth.

Revolutionizing hepatitis C treatment: next-gen direct-acting antivirals

INTRODUCTION

With the introduction of highly effective and safe therapies with next-generation direct-acting antivirals (DAAs), that act without interferon, hepatitis C virus (HCV) infection remains the only treatable chronic infectious disease.

AREAS COVERED

The review aims to provide an overview of the therapy revolution with a description of specific DAAs, their mechanisms of action, a summary of the safety and efficacy of specific regimens, and a discussion of populations requiring special therapeutic approaches.

EXPERT OPINION

DAAs are highly effective, safe, and easy to use. However, challenges such as access to health services and loss of patients from the cascade of care, especially in groups disproportionately affected by HCV infection, such as substance abusers, make it difficult to achieve the WHO's goal of HCV elimination. The proposed strategy to combat these difficulties involves a one-step approach to diagnosing and treating the infection, the availability of long-lasting forms of medication, and the development of an effective vaccine. The aforementioned opportunities are all the more important as the world is facing an opioid epidemic that is translating into an increase in HCV prevalence. This phenomenon is of greatest concern in women of childbearing age and in those already pregnant due to treatment limitations.

Ongoing Gaps in the Hepatitis C Care Cascade during the Direct-Acting Antiviral Era in a Large Retrospective Cohort in Canada: A Population-Based Study

To achieve hepatitis C virus (HCV) elimination, high uptake along the care cascade steps for all will be necessary. We mapped engagement with the care cascade overall and among priority groups in the post-direct-acting antivirals (DAAs) period and assessed if this changed relative to pre-DAAs. We created a population-based cohort of all reported HCV diagnoses in Quebec (1990-2018) and constructed the care cascade [antibody diagnosed, RNA tested, RNA positive, genotyped, treated, sustained virologic response (SVR)] in 2013 and 2018. Characteristics associated with RNA testing and treatment initiation were investigated using marginal logistic models via generalized estimating equations. Of the 31,439 individuals HCV-diagnosed in Quebec since 1990 and alive as of 2018, there was significant progress in engagement with the care cascade post- vs. pre-DAAs; 86% vs. 77% were RNA-tested, and 64% vs. 40% initiated treatment. As of 2018, a higher risk of not being RNA-tested or treated was observed among individuals born <1945 vs. >1965 [hazard ratio (HR); 95% CI; 1.35 (1.16-1.57)], those with material and social deprivation [1.21 (1.06-1.38)], and those with alcohol use disorder [1.21 (1.08-1.360]. Overall, non-immigrants had lower rates of RNA testing [0.76 (0.67-0.85)] and treatment initiation [0.63 (0.57-0.70)] than immigrants. As of 2018, PWID had a lower risk of not being RNA tested [0.67 (0.61-0.85)] but a similar risk of not being treated, compared to non-PWID. Engagement in the HCV care cascade have improved in the post-DAA era, but inequities remain. Vulnerable subgroups, including certain older immigrants, were less likely to have received RNA testing or treatment as of 2018 and would benefit from focused interventions to strengthen these steps.
