Elements of community-based models for treating hepatitis C virus in supporting HCV elimination in Australia: A Delphi study

Priority setting for Canadian Take-Home Naloxone best practice guideline development: an adapted online Delphi method

BACKGROUND

Take-Home Naloxone (THN) is a core intervention aimed at addressing the toxic illicit opioid drug supply crisis. Although THN programs are available in all provinces and territories throughout Canada, there are currently no standardized guidelines for THN programs. The Delphi method is a tool for consensus building often used in policy development that allows for engagement of stakeholders.

METHODS

We used an adapted anonymous online Delphi method to elicit priorities for a Canadian guideline on THN as a means of facilitating meaningful stakeholder engagement. A guideline development group generated a series of key questions that were then brought to a 15-member voting panel. The voting panel was comprised of people with lived and living experience of substance use, academics specializing in harm reduction, and clinicians and public health professionals from across Canada. Two rounds of voting were undertaken to score questions on importance for inclusion in the guideline.

RESULTS

Nine questions that were identified as most important include what equipment should be in THN kits, whether there are important differences between intramuscular and intranasal naloxone administration, how stigma impacts access to distribution programs, how effective THN programs are at saving lives, what distribution models are most effective and equitable, storage considerations for naloxone in a community setting, the role of CPR and rescue breathing in overdose response, client preference of naloxone distribution program type, and what aftercare should be provided for people who respond to overdoses.

CONCLUSIONS

The Delphi method is an equitable consensus building process that generated priorities to guide guideline development.

'I'm over the moon!': patient-perceived outcomes of hepatitis C treatment

Understanding patient-perceived outcomes is crucial for assessing the effectiveness and acceptability of hepatitis C virus (HCV) treatment. This study aimed to explore patient-perceived outcomes of receiving direct-acting antivirals (DAAs). This study was a part of a mixed-methods case study of the Prince Charles Hospital program for improving access to HCV treatment in community settings. Data were collected using semi-structured interviews with nine patients who were in different stages of their treatment for HCV. The participants were recruited using purposive sampling. All interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis. Patients emphasised 'having more energy' when reporting improvements in their physical health following treatment. They also reported a newly developed sense of freedom and hope. Improved physical and mental health empowered them to start a healthy lifestyle and to practise self-protection from the risk of re-infection. Patients highlighted their desire to help other patients to receive treatment, which was connected to their experience of the services that they received and their perceived health outcomes. Patients expect and experience various outcomes that are related to the physical, psychological and social aspects of living with, and being cured of HCV. Emphasis on the short-term outcomes of receiving HCV treatment may improve HCV treatment uptake and adherence rates.

Hepatitis C treatment in a co-located mental health and alcohol and drug service using a nurse-led model of care

Hepatitis C virus (HCV) is more prevalent among people with experience of severe mental illness compared to the general population, due in part to higher levels of injecting drug use. Delivering HCV care through mental health services may reduce barriers to care and improve outcomes. A nurse-led HCV program was established in a co-located mental health and addiction service in Melbourne, Australia. People with a history of injecting drug use, including current use, were referred for HCV testing by nurses, with support provided on-site from a general practitioner and remotely from infectious disease and hepatology specialists. A nurse practitioner, general practitioner or specialists were able to prescribe HCV treatment. One-hundred and thirty people were referred to the nurse-led service, among whom 112 (86%) were engaged in care. Of those 112, 84 (75%) were found to have detectable HCV RNA, 70 (83%) commenced treatment; 28 (40%) prescriptions were nurse initiated, 19 (27%) were general practitioner initiated and 20 (29%) were prescribed from hospital clinics or elsewhere. All people with an SVR result (48/70) achieved HCV cure (intention to treat SVR 69%, per-protocol SVR 100%). Treatment commencement was highest among people prescribed opioid agonist therapy (28/29, 96%) compared to those who were not (18/26, 69%). In conclusion, a nurse-led, HCV service for people with severe mental illness including pathways to specialist support when needed can achieve high treatment uptake and cure. Further implementation work is required to improve treatment uptake, particularly among people not prescribed opioid agonist therapy, and to improve follow-up for SVR testing.

Challenges of transferring rural adults with chronic HCV infection for further HCV RNA confirmation and free DAAs treatment: a success story of the interdisciplinary collaboration approach

Background

Chronic hepatitis C virus (HCV), which is a concern in many countries, is the leading cause of liver cancer around the world. Since Taiwan launched its national health insurance system in 1995, it has managed to extend health coverage to 99% of the Taiwanese population, providing free but limited antiviral treatment each year since 2017. However, many people in rural areas are unaware that they have chronic HCV; nor do they realize that new drugs with high cure rates could drastically reduce their health burden. The aim of this study is to explore the implementation facilitators of and barriers to inviting potentially infected patients in rural areas to be transferred for HCV ribonucleic acid (RNA) confirmation and new drug treatment.

Methods

A descriptive and prospective study design with an interdisciplinary collaboration approach was implemented. After five elements of referral were developed, telephone counseling was conducted between August 2018 and May 2019 in Yunlin, Taiwan. The elements of referral developed by the research team were: (1) forming and coordinating physicians’ schedules, (2) recruiting and training volunteers, (3) training the nursing staff, (4) raising funds or resources, and (5) connecting with village leaders. Thereafter, we collaborated with two district health centers, a private local hospital, and health clinics. Based on the medical records provided by these agencies, community adults that were HCV antibody (anti-HCV) positive were invited to join the program.

Results

Of the 1795 adults who were serum anti-HCV positive, 1149 (64%) accepted transfer to a qualified hospital; of these, 623 (54.2%) had an HCV infection. 552 (88.6%) of those infected started receiving direct-acting antivirals (DAAs) treatment. The top four barriers to accepting transfer were: (1) they perceived themselves to be healthy (n = 98, 32.3%); (2) mistrust of treatment/healthcare (n = 60, 20.2%); (3) limited transportation to the hospital (n = 52, 17.5%); and (4) work conflict (n = 30, 10.1%).

Conclusion

An interdisciplinary collaboration approach significantly contributed to the invitation of CHC patients, as well as their acceptance of HCV RNA confirmation and free DAAs treatment. Using anti-HCV data from previous medical records for case-finding and collaborating with a hospital and health clinics proved to be an efficient strategy.

Accelerating the elimination of hepatitis C in Kuwait: An expert opinion

The hepatitis C virus (HCV) is estimated to affect 71 million people worldwide. In 2016, the World Health Organization adopted the first global health sector strategy to eliminate viral hepatitis as a public health threat by 2030. In December 2018, the European Association for the Study of the Liver, International Liver Foundation convened an expert panel to address the elimination of HCV in Kuwait. Several steps have already been taken to eliminate HCV in Kuwait, including free HCV treatment for Kuwait's citizens, high blood safety standards, and the implementation of screening and awareness programs. The expert panel made several recommendations aimed at accelerating the elimination of HCV in Kuwait: The development of a national strategy and action plan to guide all HCV elimination activities; the formation of a coordination mechanism to support collaboration between hepatitis working committees; the prioritization of micro-elimination at primary, secondary or tertiary facilities, in prisons and rehabilitation centers; and ensuring the involvement of multiple stakeholders - including relevant civil society groups - in all activities. Enhanced screening and linkage to care should be prioritized in Kuwait, with the expansion of the prescriber base to primary healthcare providers and nurse practitioners to be considered. Raising awareness and educating people about HCV infection also remain essential to achieve the goal of HCV elimination. Lastly, a national HCV registry should be developed to help monitor the implementation of viral hepatitis plans and progress towards achieving national and international targets.

Hepatitis C cascade of care at an integrated community facility for people who inject drugs

OBJECTIVE

To examine the hepatitis C virus (HCV) cascade of care at a community-based integrated harm reduction and treatment facility for people who inject drugs (PWID).

METHODS

Queensland Injectors' Health Network is a community-based agency providing integrated harm reduction and treatment services, including HCV treatment. Program data were analyzed from program commencement (early 2015) up to December 2017.

RESULTS

By December 2017, 476 participants with confirmed HCV infection had enrolled in treatment, of whom 72% had commenced treatment, 65% had completed treatment, and 44% had a confirmed sustained virologic response at 12-weeks post-treatment. Participants who commenced treatment tended to be older (ref 18-34 years; 35-49 years OR = 1.84, p = 0.037, 50+ years OR = 3.19, p = 0.002) and to feel safe and stable in their housing (OR = 2.36, p = 0.021). Participants who completed treatment were less likely to report legal issues (OR = 0.23, p = 0.009).

CONCLUSIONS

Integrated community-based services can successfully engage PWID throughout the HCV treatment journey. Additional social support, including linkage with housing and legal navigation services, may improve treatment uptake and completion. Point-of-care testing, including same-day scripting, could improve treatment uptake.

Enablers and barriers for the provision of community-based HCV treatment: A case study of a real-world practice

BACKGROUND

Although the availability of fully funded direct-acting antivirals (DAAs) and the eligibility of primary care providers (PCPs) to provide hepatitis C virus (HCV) have removed barriers related to access to hospital-based HCV treatment in Australia, there are still many barriers to the provision of HCV treatment in community settings. There is a lack of knowledge regarding the barriers to, and enablers of HCV treatment in community settings in Australia. This study aimed to identify barriers and enablers for the provision of community-based HCV treatment.

METHODS

This study was a part of a mixed-method case study of the Cure-It programme. The programme was studied to better understand barriers and enablers experienced by stakeholders of such programmes. The programme is delivered through the Prince Charles Hospital in Brisbane, Australia, and aimed to improve access to HCV treatment in community settings. Data were collected using semi-structured interviews with 12 healthcare providers and nine patients between July and December 2018. Purposive sampling was used to ensure diverse views were captured. The interview transcripts were analysed using inductive thematic analysis.

RESULTS

Ease of access to specialist support, easy and high value treatment, co-location with or providing other services and motivated patients enabled PCPs to be engaged with the Cure-It programme. Several interconnected factors related to patients' characteristics and health system acted synergistically to enable patients to initiate and complete treatment. These included a desire to remove HCV as a source of shame, having children, awareness of HCV consequences, access to DAAs for free, ease of access to general practices and drug and alcohol services, and access to a safe and enabling environment. The identified barriers were interconnected at the levels of patients, PCPs and primary care systems and acted synergistically to prevent patients and PCPs from becoming engaged with HCV treatment. PCPs' related barriers included a lack of knowledge, their perception of HCV as a specialist area and of patients with HCV as 'hard to manage' patients along with the practice preferences and priorities. Patients' related barriers included their socioeconomic characteristics, internalized stigma, perception of not being sick and lack of knowledge. Additionally, the unavailability of support for patients and existence of stigma in primary health care, along with poor communication between the hospital and primary care system, and the unavailability of FibroScan^® in primary care discouraged PCPs and patients engagement specifically with the provision of community-based HCV treatment.

CONCLUSION

Various strategies are needed to improve PCPs and patients' knowledge and awareness of HCV treatment. Training and support for PCPs need to be easy to access and should cover both clinical and social aspect of HCV. Connecting PCPs to other related services may improve PCPs' and patients' engagement with HCV treatment.

Outcomes of a tertiary-based innovative approach to engage primary care providers in provision of hepatitis C treatment in community settings

Background

Australia is committed to eliminating the hepatitis C virus (HCV) by 2030. Despite regulations in Australia that enable the prescription of subsidised direct acting antiviral (DAA) by primary health care providers, the number of providers who treat patients for HCV remains low and this limits the prospect of HCV elimination. The Prince Charles Hospital, Brisbane, Australia, implemented an innovative program called Cure-It aimed at engaging primary care providers in community-based HCV treatment. This paper aims to describe initial experiences and short-term patient outcomes of this program.

Methods

A formative evaluation was conducted using program data for the period March 2016 to April 2018. Descriptive statistics were used to report the number of engaged primary care providers, patients’ baseline characteristics, treatment plans, and treatment outcomes.

Results

Thirty primary care providers from different settings were engaged in HCV treatment. Among 331 patients eligible for community-based treatment, 315 (95.2%) commenced treatment, the completion rate was 92.4 and 66.5% achieved sustained virological response at 12 weeks (SVR12). The SVR12 had not been documented for 26.8% of patients. Among patients whose SVR12 was documented, 98.2% achieved SVR12. Only 1.3% of patients experienced treatment failure.

Conclusion

A flexible tertiary-led model can improve primary care providers and patients’ engagement with provision of HCV treatment. Tertiary centres need to play their role to improve the accessibility of HCV treatment through providing training and on-going support for primary care providers while enabling those providers to become more confident in providing treatment independently.
