<p>The original article is available at <a href="https://bmjopen.bmj.com/content/8/4/e019315.long">bmjopen.bmj.com</a></p> <p><strong>OBJECTIVE:</strong> To examine the impact of the Preferred Drugs Initiative (PDI), an Irish health policy aimed at enhancing evidence-based cost-effective prescribing, on prescribing trends and the cost of prescription medicines across seven medication classes.</p> <p><strong>DESIGN:</strong> Retrospective repeated cross-sectional study spanning the years 2011</p> <p><strong>SETTING:</strong> Health Service Executive Primary Care Reimbursement Service pharmacy claims data for General Medical Services (GMS) patients, approximately 40% of the Irish population.</p> <p><strong>PARTICIPANTS:</strong> Adults aged ≥18 years between 2011 and 2016 are eligible for the GMS scheme.</p> <p><strong>PRIMARY AND SECONDARY OUTCOMES:</strong> The percentage of PDI medications within each drug class per calendar quarter. Linear regression was used to model prescribing of the preferred drug within each medication group and to assess the impact of PDI guidelines and other relevant changes in prescribing practice. Savings in drug expenditure were estimated.</p> <p><strong>RESULTS:</strong> Between 2011 and 2016, around a quarter (23.59%) of all medications were for single-agent drugs licensed in the seven drug classes. There was a small increase in the percentage of PDI drugs, increasing from 4.64% of all medications in 2011 to 4.76% in 2016 (P</p> <p><strong>CONCLUSION:</strong> There has been a small increase in prescribing of PDI drugs in response to prescribing guidelines, with inconsistent changes observed across therapeutic classes. These findings are relevant where health services are seeking to develop more active prescribing interventions aimed at changing prescribing practice.</p>
