Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Multiple and intensive demand measures in Scotland have appreciably enhanced prescribing efficiency for proton pump inhibitors (PPIs) and statins in 2007 versus 2001. Statin utilization enhanced by measures to increase doses prescribed, including the Quality and Outcome Framework (QoF). Aims to ascertain whether the plethora of measures continue to enhance prescribing efficiency for PPIs and statins. Second, assess whether the combined impact of the QoF targets and guidance enhances the prescribing of higher strength statins, mirroring the situation in England. PPI and statin utilization measured in terms of defined daily doses (DDDs) and DDDs per 1000 inhabitants per day (2010 DDDs) between 2001 and 2010, number and strength of simvastatin and atorvastatin tablets dispensed, and reimbursed expenditure per DDD and 1000 inhabitants per year. Expenditure per DDD for generic omeprazole in 2010 was 91% below the 2001 originator price, leading to expenditure per 1000 inhabitants for PPIs in 2010 to be 56% below 2001 despite a threefold increase in utilization. Expenditure per DDD for generic simvastatin in 2010 was 97% below the 2002 originator price. Expenditure per 1000 inhabitants for statins in 2010 only increased by 7% compared with 2001 despite a 6.2-fold increase in utilization. Utilization of higher strength statins has increased in recent years, with higher strength simvastatin (40 and 80 mg) accounting for 85% of total statins (DDD basis) in 2010. Reforms appear to be working to further enhance prescribing efficiency. Utilization of higher strength statins in recent years should further improve outcomes.
