Does preoperative education reduce anxiety in patients undergoing coronary artery bypass surgery?

The main purpose of the study was to find out whether preoperative education helps in reducing anxiety in patients undergoing coronary artery bypass surgery (CABG), by means of systematic review. About 28,000 CABG surgeries are done in UK every year, but there is variation in terms of number of surgeries from place to place. Patients undergoing CABG faces many psychological issues such as anxiety and depression that may bring the worse outcome of the surgery and even leads to death or another cardiac event. This systematic review brings all these issues into light and 14 relevant studies obtained by search methodology have discussed the issues such as effect of anxiety on coronary heart disease, effect of preoperative patient education on the outcome of the surgery and the different forms of education and their effects. It was reported that anxiety does predict the post operative psychological outcome. Positive association were observed between different forms of education such as support from peer group and music and video information. The systematic review concluded that there is positive effect of education given to the patient prior to surgery, but few more studies need to be performed on large cardiac population to obtained better results for the practical implementation
