A cluster randomized controlled trial of a MedicineInsight Educational Quality Improvement Programme to improve the diagnosis and treatment of chronic hepatitis C in general practice (the EQUIP‐HEPC trial)

The availability of direct‐acting antivirals (DAAs) sparked efforts to eliminate hepatitis C virus (HCV) in Australia. We evaluated whether an educational intervention of a 1‐h discussion among staff using audit and feedback data from the MedicineInsight GP programme would improve DAA uptake. Of 296 eligible general practices in MedicineInsight, 11% opted out. Randomization stratified by practice caseload allocated 130 practices to the intervention arm and 129 to control. The primary outcome was the number of patients started on DAAs over 6 months using the negative binomial regression model adjusted for DAA prescription history and clustering by practice. Data for analysis were available for 78% of practices, which included 101 practices and 2469 DAA‐naive patients with confirmed/possible HCV in the intervention arm, and 100 practices and 2466 patients in the control arm. At baseline, 49.5% of practices had prescribed ≥1 DAA in the past year; 18.9% of HCV patients had already been treated with DAAs; the mean age of DAA‐naive HCV patients was 43 years old, and 57% were men. Over 6 months, 43 patients in the intervention arm and 36 in the control arm started DAAs (adjusted IRR 1.19; 95% CI 0.67–2.11, p = 0.55). In the first 3 months, 27 vs 16 patients started DAAs (adjusted IRR 1.77, 0.88–3.58; p = 0.111). Few patients were started on DAAs, and a facilitated discussion in HCV management did not lead to a significant increase. Alternative measures, such as incentivizing GP initiations or patients, are suggested to address remaining barriers to DAA uptake in Australian primary care.
