Paul MS-275 price Deslandes1,2, Kate Jenkins1, Kath Haines1, Tessa Lewis1 1All Wales Therapeutics and Toxicology Centre, Cardiff, UK, 2Cardiff University School of Pharmacy and Pharmaceutical Sciences, Cardiff, UK National Prescribing Indicators (NPIs) have been used by the All Wales Medicines Strategy Group (AWMSG) to promote safe and cost-effective prescribing in key therapeutic areas since 2004. The rate of change in medicine use in the 12 months prior to and post introduction was used to assess the impact of each NPI. NPIs had a varied impact on prescribing in Wales. In 2004, AWMSG introduced NPIs to promote safe and cost-effective prescribing in Wales, with two types of measure used1: The proportion of one or more medicines as a percentage of a denominator group, e.g. ibuprofen and naproxen as a percentage of total non-steroidal anti-inflammatory drugs (NSAIDs). Absolute prescribing http://www.selleckchem.com/products/LBH-589.html for individual medicines or groups of medicines, e.g. NSAIDs measured as defined daily doses (DDDs)/1,000 prescribing units (PUs). GP practices in Wales are encouraged to move

towards the NPI threshold as part of a prescribing incentive scheme. The aim of this study was to examine whether specific

NPIs Carbohydrate changed associated prescribing following their introduction. The rate of change in medicines use was measured in the 12 months prior to and post introduction of each NPI. Proportional usage indicators were: 1. Generic prescribing as a percentage of all prescribing; 2. Low acquisition cost (LAC) proton pump inhibitors (PPIs) as a percentage of all PPIs; 3. LAC statins as a percentage of all statins and ezetimibe; 4. ACE inhibitors as a percentage of all medicines affecting the renin angiotensin system; and 5. Ibuprofen and naproxen as a percentage of all NSAIDs. Absolute usage indicators (with prescribing measure in parentheses) were: 1. Hypnotics and anxiolytics (H&A) (DDDs/1,000 patients); 2. Dosulepin (DDDs/1,000 PUs); 3. Total NSAIDs (DDDs/1,000 PUs); and 4. Total PPIs (DDDs/1,000 PUs). Primary care usage data was obtained using the Comparative Analysis System for Prescribing Audit (CASPA) version 1.0.4.7 (NHS Wales Shared Services Partnership [NWSSP]) accessed online February 2013. This software provides a record of all dispensed WP10 prescriptions forwarded to Prescribing Services, NWSSP for processing and payment. Changes in prescribing over time were compared using linear regression analysis. Data were analysed using GraphPad Prism version 5 (GraphPad Software, California, USA).
