BACKGROUND
Hepatitis C (HCV) infection is common among people who inject drugs (PWID), yet well described barriers mean that a minority have accessed HCV treatment.
OBJECTIVE
The aim of this study was to examine feasibility, acceptability, clinical and cost effectiveness of an integrated model of HCV care for opioid substitution treatment (OST) patients in general practice.
METHODS
A pre-and-post intervention design with an embedded economic analysis was used to establish the feasibility, acceptability, clinical and cost effectiveness of a complex intervention to optimise HCV identification and linkage to HCV treatment among patients prescribed methadone in primary care. The ‘complex intervention’ comprised General Practitioner (GP) / practice staff education, nurse-led clinical support, and enhanced community-based HCV assessment of patients. General practices in North Dublin were recruited from the professional networks of the research team and from GPs who attended educational sessions.
RESULTS
Fourteen practices, 135 patients participated. Follow-up data was collected six-months post-intervention on 131(97.0%) patients. With regards to clinical effectiveness, among HCV antibody-positive patients, there was a significant increase in the proportions of who had a liver fibroscan (17/101(16.8%) vs 52/100 (52.0%); p<0.001), had attended hepatology/infectious diseases services (51/101(50.5%) vs 61/100 (61.0%); p=0.002), and initiated treatment (20/101(19.8%) vs 30/100 (30.0%); p=0.004). The mean incremental cost-effectiveness ratio of the intervention was €13,255 per quality adjusted life year gained at current full drug list price (€39,729 per course), which would be cost saving if these costs are reduced by 88%.
CONCLUSIONS
The complex intervention involving clinical support, access to assessment and practitioner education has the potential to enhance patient care, improving access to assessment and treatment in a cost effective manner.
