Background: The health benefits of an active lifestyle have been extensively documented and generally accepted. In the UK, declining physical activity levels are a major contributing factor to a number of public health concerns such as obesity and coronary heart disease. Clearly, there is an urgent need to support people in developing sustainable active lifestyles. In 2003, a new lifestylebased physical activity service called Active Lifestyles (AL) was set up in Kingston-upon-Hull to help local residents to become more active and develop healthier lifestyles. The service targeted the most deprived communities in the city. The aim of the study was to explore participants' perceptions of the operation and effectiveness of the AL service.

Medical errors directly impact patient outcomes and hospitals' profitability, especially since 2008 when Medicare stopped reimbursing hospitals for care related to certain preventable medical errors. Hospitals must rigorously analyze causes of medical errors and implement comprehensive preventative programs to reduce their occurrence as the financial burden of medical errors shifts to hospitals.

Fistulas are often a difficult and costly complication of CD. This study determined that patients with fistulizing CD have higher healthcare costs and resource consumption than patients without fistula. Use of therapies that heal fistulas may help deter some of the high costs and intensive resource utilization found in this study. Economic analyses need to account for these issues when assessing the cost-effectiveness of therapies targeting fistulizing disease.
