Ferket and colleagues could have added to their long list a guideline from the Haute Autorité de Santé (High Authority for Health, the French agency for quality of care) which recommended in 2006 for the screening peripheral artery disease and its treatment with aspirin, despite evidence was lacking.(1,2)
This French recommendation is surprising because: a) aspirin does not have a marketing authorization for such a use; b) it was even published in the official bulletin of the French republic to enforce good clinical practices.(3)
Guidelines are generally characterized by poor methodology but the main concern is the neurotic quest of many bodies to issue recommendations for acting despite poor evidence. Only the US Preventive Services Task Force (USPSTF) dare to recommend against routine screening for peripheral arterial disease (Grade: D) as evidence was lacking.(4)
From April 1998 to October 2008, the Aspirin for Asymptomatic Atherosclerosis trial screened 28,980 men and women aged 50 to 75 years, free of clinical cardiovascular disease.(5) Of those, 3,350 with a low ankle brachial index (< or = 0.95) were entered in an intention-to-treat double-blind randomized controlled trial comparing aspirin vs placebo. Aspirin resulted in neither reduction in mortality nor reduction in cardio-vascular events but caused major hemorrhage (HR, 1.71; 95% CI, 0.99-2.97).
Five of the guidelines scrutinized by Ferket and colleagues advocated for screening.(1) This was waste of money as systematic reviews for a complex clinical topic may cost in the range of $300,000 to $350,000 or more (communication from Beth A. Collins Sharp, director, Evidence-Based Practice Centers Program, Agency for Healthcare Research and Quality, November 14, 2008). Failure to withdraw or to update these five guidelines enduringly results in inappropriate care to healthy people.

NOTE: Conflict of interests– Dr Braillon, a senior tenured consultant in Public Health was sacked in Sept 2010 by the National Management Centre (French Department of Health) against the advice of the National Statutory Committee. He won a lawsuit in Sept 2011 against the Haute Autorité de Santé for breach of the Freedom of Information Act but the Haute Autorité de Santé failed to apply the judgment.(Lee SS.
