This approach strengthens the evidence-based foundation for therapeutic application of these guidelines. The committee acknowledges that in many trials there is under-representation of ethnic minorities, women, and the elderly. 11 Cigarette Smoking Recommendations Goal: Complete Cessation and No Exposure to Environmental Tobacco Smoke •Ask about tobacco use status at every visit. •Advise every tobacco user to quit. •Assess the tobacco user’s willingness to quit.

Nichol et al. N Engl J Med 2003;348:1322-32. 67 The Need to Implement Secondary Prevention Multiple studies of the use of these recommended therapies in appropriate patients continue to show that many patients in whom therapies are indicated are not receiving them in actual clinical practice. The AHA and ACC urge that in all medical care settings where these patients are managed that programs to provide practitioners with useful reminder clues based on the guidelines, and continuously assess the success achieved in providing these therapies to the patients who can benefit from them be implemented. Encourage that the AHA’s Get With the Guidelines and/or ACC’s Guidelines Applied to Practice Programs be instituted to identify appropriate patients for therapy 68 AHA GWTG Program GWTG is a national initiative of the AHA to improve guidelines adherence in patients hospitalized with cardiovascular disease. GWTG uses collaborative learning sessions, conference calls, e-mail and staff support to assist hospital teams improve acute and secondary prevention care systems. A web-based Patient Management Tool is used for point of care data collection and decision support, on-demand reporting, communication and patient education. 69 SIMPLE, ONE PAGE, ON-LINE FORM Demographics 6 clicks Clinical/Lab 8 clicks Dischargemeds and interventions 7 clicks Interactively checks patient’s data with the AHA guidelines 70 ©2001 Outcome Sciences, Inc.
