Laying the foundations for hepatitis C elimination: evaluating the development and contribution of community care pathways to diagnostic efforts.

BACKGROUND: Hepatitis C Virus (HCV) is a public health threat which contributes substantially to the global burden of liver disease. There is much debate about effective approaches to scaling up diagnosis of HCV among risk groups. Tayside, a region in the East of Scotland, developed low-threshold community pathways for HCV to lay the foundations of an elimination strategy. In this retrospective study, we sought to: quantify the contribution of community pathways to increasing HCV diagnosis; understand if shifting diagnosis to community settings led to a higher proportion of individuals tested for HCV being actively infected; and describe functional characteristics of the care pathways. METHODS: Descriptive statistics were used to for analysis of routinely-collected HCV testing data from 1999 to 2017, and a review of the development of the care pathways was undertaken. Community-based testing was offered through general practices (GP); nurse outreach clinics; prisons; drug treatment services; needle and syringe provision (NSP) sites; community pharmacies; and mosques. RESULTS: Anti-HCV screening was undertaken on 109,430 samples, of which 5176 (4.7%) were reactive. Of all samples, 77,885 (71.2%) were taken in secondary care; 25,044 (22.9%) in GPs; 2970 (2.7%) in prisons; 2415 (2.2%) in drug services; 753 (0.7%) in NSPs; 193 (0.2%) pharmacies; and 170 (0.1%) in mosques. The highest prevalence of HCV infection among those tested was in NSP sites (26%), prisons (14%), and drug treatment centres (12%). CONCLUSIONS: Decentralised care pathways, particularly in harm reduction and other drug service settings, were key to increasing diagnosis of HCV in the region, but primary and secondary care remain central to elimination efforts.

A quasi-experimental evaluation of dried blood spot testing through community pharmacies in the Tayside region of Scotland.

OBJECTIVE: Comparison of uptake of dried blood spot testing (DBST) for hepatitis C virus (HCV) infection between community pharmacies and established services. DESIGN: Quantitative evaluation of a service development with qualitative process evaluation undertaken in parallel. SETTING: Six pharmacies from 36 community pharmacies within Dundee City, a large urban settlement with high levels of socioeconomic deprivation. PARTICIPANTS: Patients in receipt of opioid substitution therapy (OST) not tested for HCV within 12 months. The 6 pharmacies provided OST for approximately 363 patients from a cohort of 1385 patients within Dundee City. INTERVENTION: Provision of DBST by pharmacists. MAIN OUTCOME MEASURE: Receipt of DBST between January and December 2014. RESULTS: 43 of 143 service users with no record of testing from the 6 community pharmacies accepted DBST. Of 561 from the remaining 1022 service users with no record of testing, 75 were tested for HCV (30% vs 13%). The OR for increased uptake of testing within the 6 pharmacies was 2.25 (95% CI 1.48 to 3.41, Z statistic=3.81, p=<0.0001) compared with other services. The DBST taken by the pharmacies provided 12 patients with a reactive test. The process evaluation identified key themes important to staff and recipients of the service. A logic model was constructed. LIMITATIONS: Non-experimental service evaluation performed in community pharmacies records service activity in one location across a single time period. INTERPRETATION: Some evidence that DBST from community pharmacies may be feasible. Service users received the service positively. Staff reported that DBST was straightforward and achievable.

DOT-C: A cluster randomised feasibility trial evaluating directly observed anti-HCV therapy in a population receiving opioid substitute therapy from community pharmacy.

BACKGROUND: Direct-acting antiviral therapy (DAAs) for hepatitis C infection (HCV) have a much smaller burden of treatment than interferon-based regimes, require less monitoring and are very effective. New pathways are required to increase access to treatment amongst people prescribed opioid substitution therapy (OST). METHODS: An exploratory cluster randomised controlled trial with mixed methods evaluation was undertaken to compare the uptake of dried blood spot testing (DBST) and treatment of people with genotype 1 HCV infection in a conventional service pathway versus a pharmacist-led pathway in a population receiving OST. RESULTS: Pharmacies randomised to the conventional pathway obtained 58 DBST from 244 patients (24%):15 new reactive tests and 33 new negative tests were identified. Within the pharmacist-led pathway, 94 DBST were obtained from 262 patients (36%): 26 new reactive tests and 54 new negative tests were identified. Participants in the pharmacist-led pathway were more likely to take a DBST (p<0.003). Of participants referred for treatment through the conventional pathway, 4 patients from 15 with new reactive tests (27%) attended clinic for assessment. In the pharmacist-led treatment pathway, 20 patients from 26 with new reactive tests (77%) attended for assessment blood tests. Participants in the pharmacist-led pathway were more likely to proceed through the assessment for treatment (p<0.002). One participant completed treatment through the conventional pathway and three patients completed treatment through the pharmacist-led pathway. The process evaluation identified key themes important to service user completers and staff participants. CONCLUSION: The study provides evidence that testing and treatment for HCV in a pharmacist led-pathway is a feasible treatment pathway for people who receive supervised OST consumption through community pharmacies. This feasibility trial therefore provides sufficient confirmation to justify proceeding to a full trial.

Scottish Home Parenteral Nutrition Managed Clinical Network: coordination and standards.

Home parenteral nutrition is required by patients with intestinal disease such that they are unable to maintain nutritional status or fluid volume without this treatment. A Managed Clinical Network has been established in Scotland. The aims of this multi-professional group are to ensure equity of access and that patients are managed according to nationally-agreed evidence-based procedures and protocols. The Clinical Standards Board for Scotland has provided support in preparing a quality-assurance framework to which the network must adhere.
