Background and purpose: The outpatient exercise training is commonly prescribed for patients after coronary artery bypass grafting (CABG). The purpose of this study was to examine the effect of the outpatient exercise training patients after CABG on quality adjusted life year (QALY). Methods: During the period of January 1994 to October 2001, 65 patients participated in an outpatient exercise training and 70 controls without training after CABG were recruited from three hospitals. The data were collected on their demographic characteristics and quality of life by the WHOQOL (World Health Organization Quality of Life) questionnaire. The QALY was calculated by Monte Carlo-quality adjusted survival estimation. Results: Patients in the exercise group demonstrated significantly higher scores in the environment domain of the WHOQOL and the QALY gained from exercise training was 0.069 year for the environment domain in the 7-year survival period. Conclusion: The outpatient exercise training is beneficial on the QALY of patients after CABG.
