Abstract:
The purposes of this predictive research study aimed to examine the health status and to examine whether ages, functional classes, ejection fraction, comorbidity, knowledge of the disease and operation, and self-care behavior could predict the health status in patients with coronary artery bypass graft surgery (CABG). Data were collected from 123 patients with CABG (males and females) aged between 18 and 59 years were recuited from a multistage random sampling in the cardiac clinic at the Ramathibodi Hospital and Pharmongkutklao Hospital. The instruments were composed of demographic information, comorbidity, knowledge of the disease and operation, self-care behavior, and the short form-36 health survey (SF-36) questionare. The content validity index (CVI) of these questionares were .80, .90, and .83 respectively and reliabilities of these questionares were .96, .81, .83, and .86 respectively. Descriptive and Stepwise multiple regression statistics were used to analyze data. The results revealed: 1. The mean score of the health status in CABG patients was good. (Mean = 58.03, S.D. = 3.90) 2. Self-care behavior, ejection fraction, and knowledge of the disease were positively related to health status in patients with CABG at the level of .05 (r = .678, .583, and .549, respectively) and comorbidity, ages, functional classes were negatively related to health status of patients with CABG at the level of .05 (r = -.565, -.554, and -.537, respectively). In addition, Self-care behavior, comorbidity, functional classes, ages, ejection fraction, and knowledge of the disease were good predictors with 74% of total variances explained for health status in patients with coronary artery bypass graft (R2 = .740, p < .05).
