A prospective, multisite implementation-efficacy trial of a collaborative prescriber-pharmacist model of care for Medication Assisted Treatment for Opioid Dependence: Protocol for the EPIC-MATOD study

Medication Assisted Treatment for Opioid Dependence (MATOD) is clinically effective and cost effective, yet a lack of MATOD prescribers in the community limits access to this treatment in Australia. These shortages are often greatest in regional and rural areas.

The Enhancing Pharmacist Involvement in Care (EPIC)-MATOD study will evaluate clinical and implementation outcomes among people with opioid dependence receiving MATOD through a collaborative pharmacist-prescriber model of care across multiple sites in a regional location (encompassing a mix of metropolitan and non-metropolitan areas) of Victoria, Australia.

The EPIC-MATOD study is a prospective, multisite, implementation trial of collaborative MATOD care. Pharmacists and prescribers will be recruited through the local network of opioid pharmacotherapy providers. Patients will be recruited through participating healthcare providers. After induction into the collaborative care model, patients and healthcare professionals will be followed up over 6- (patients) and 12-months (pharmacists and prescribers) in a hybrid implementation-efficacy study, with outcomes mapped to the RE-AIM framework. The primary clinical efficacy endpoint is patient retention in treatment at 26 weeks. The primary implementation outcome is treatment capacity, based on prescriber time required to provide treatment through collaborative care compared with traditional care. Secondary clinical endpoints include attendance for dosing and clinical reviews, substance use, mental and physical health and overall well-being. Implementation costs, acceptability, and provider engagement in collaborative care will be used as secondary implementation outcome indicators. Time and costs associated with collaborative care, and health service utilisation, will also be estimated.

The study will provide important information on outcomes and acceptability of collaborative care for MATOD, as well as the cost and key considerations in delivering a collaborative model of care in Australia and other countries where similar treatment barriers exist.
