| Summary: | 碩士 === 中臺科技大學 === 護理系碩士班 === 101 === The study aims at analyzing related factors of self-care demands of patients with coronary artery bypass graft surgery. This is a descriptive study with the purposive sampling method. Subjects of the study are patients transferred to wards in stable conditions after a coronary artery bypass graft surgery in a medical center in central Taiwan. The interview was carried out upon patients' consent and was based on a self-designed and structured questionnaire, which covers demographic variables, characteristics of conditions and surgery, and self-care demands. Consistency of the questionnaire measured with Cronbach’s Alpha coefficients is 0.957 for preventing infection, 0.878 for healthy life and 0.834 for information. In total, 82 valid questionnaires were collected from July 2012 to January 2013. The collected data were input into an Excel file and were then analyzed with SPSS version 18.0. Results show that:
1. The subjects have an average age of 63.76, mostly male with educational background of elementary school. Their average score for cardiac surgery risk as assessed is 5.56 (moderately risky).
2. Standardized score for overall self-care demands is 81.6. In the order of desirability for self-care demands according to the subjects, "preventing infection" has the highest score of 82.6; score for "information" is 81.8; and that for "healthy life" is 81.0.
3. For different surgical methods, self-care demands have significant difference in terms of information for "medicine instructions" (p＜.05): the demands of those having "da Vinci System operation" are significantly higher than those with "median sternotomy".
4. For different accessory equipment, self-care demands have significant difference in terms of "healthy food": the demands of those using off-pump machines are significantly higher than those using on-pump one (p＜.05).
5. Number of bypassed vessels is negatively related to "complications" (r = - 0.282, p = .010); left ventricular ejection fraction is positively related to "cardiac rehabilitation exercise" of the aspect of healthy life (r = 0.224, p = .043) and "medicine instructions" of the aspect of information.
6. Hierarchical regression analysis of sum of variables of all the above major factors affecting self-care demands shows that there is no significant difference in self-care demands in terms of personal backgrounds, characteristics of the condition and surgery and score for cardiac surgery risk as assessed, suggesting that the patients have same level of self-care demands regardless of their backgrounds, surgical methods and degree of seriousness of their conditions.
Recommendations based on the study are that nurses should have a set of complete health education programs on self-care demands in areas like preventing infections, healthy life and information for patients had coronary artery bypass graft surgery and the health education should be detail enough regardless of patients' backgrounds, surgical methods and degree of seriousness of their conditions.
