- The first UK consensus development conference, on coronary artery bypass surgery (CABG), was held between 21-23 November 1984. A panel of twelve listened to evidence from experts and from the conference participants. Four questions were addressed: 1) What are the pros and cons of CABG for various types of patient, in terms of survival and quality of life? 2) What are the indications for various investigations for coronary artery disease? 3) What are the size of potential pools of patients for investigations and for CABG, taking alternative therapies into account? 4) What would be the cost and implications for service organisations of increased provisions for investigations and therapy?
