The length of hospital stay after surgery is an estimate of the success rate of surgery that cannot be completely explained by demographic and medical factors. Therefore, the objective of this study was to investigate the impact of psychological factors along with medical and demographic factors on the length of hospital stay after CABG surgery. In this study, 150 patients (30 females and 120 males) were selected from the convenience sampling method, among patients referred to Tehran Heart Center of Shahid Rajaie Hospital who were candidates for CABG surgery. Patients were asked to complete the questionnaire of 21 questions for anxiety- depression- stress (DASS-21). Stepwise regression analysis for psychological, medical and demographic variables showed that the most important variables to predict the length of hospital stay after surgery were anxiety and depression, diabetes and high blood pressure, age and gender. Thus, the results showed that the use of pre-operative assessment of these variables in the clinical setting, we can identify those patients for whom surgery may not be successful.
