When Guidelines might be of use… • Infrequent events with poor outcomes • Spinal cord and steroid use…. • “I believe steroids are harmful and without benefit, yet I give them when indicated to avoid litigation.”-anonymous

Guideline chaos…example • University of Virginia 2002 • 100 clinical guidelines • 1/3 out of date • 1/3 infrequently used • 1/3 used frequently by many providers…
Guideline chaos…. • University of Virginia 2002 • Plan- Scrap most of them…. • Focus on 5 frequent scenarios… • Pain, DVT, CAP, Detox, vent care • Multidisciplinary / cross-service input • Informatics • Feedback
Are clinicians using guidelines? • Yes and no… • High risk scenarios… • Unclear clinical situations….
Are clinicians using guidelines?-modified from Bleck TP: BMJ 321 (7255):239 • Alternative evidence rating scale ;) • Class 0: Things I believe • Class 0a: Things I believe despite the data • Class 1: Randomized controlled clinical trials that agree with what I believe… • Class 2: Other prospectively collected data • Class 3: Expert opinion • Class 4: Other data that disagrees with me • Class 5: What you believe that I don’t
