Here's a Published Example of a Failed Intervention

I love how this article from Canada by Shah et al  doesn't mince words: "The cardiovascular disease management toolkit failed to reduce clinical events or improve quality of care for patients with diabetes." I also love how the article includes a plain and simple "Editors' Summary" near the top, the style of which will be familiar to anyone who has used the Standards for Quality Improvement Reporting Excellence (SQUIRE). Funding for this large-scale intervention came from the Canadian government, and the poor outcomes highlight how we need to do more -- much more -- than just mail boxes of brightly colored printed materials to family physicians if we want to improve the quality of diabetes care.
