A Discriminant Analysis of Factors Affecting Health Status among Patients After Coronary Artery Bypass Graft Surgery
Keywords:

Background: Coronary artery bypass grafting (CABG) is one of the primary treatments for coronary artery disease (CAD) and is recognized as one of the most common surgical procedures. This surgery has an impact on the health status of patients who undergo it. Objective: This research aimed to assess CABG patient health status and examine related discriminating factors of health status. Method-Material: One hundred and twenty patients who had undergone CABG (both males and females) more than 18 years old were purposively recruited from the surgical and specialty clinics at Ramathibodi Hospital, Bangkok. Questionnaires collected demographic information and information on comorbidity, knowledge of disease and operation, and self-care behavior, and included questions of the short form-36 health survey (SF-36) questionnaire. Data were described/analyzed descriptively and through discriminant analysis. Results: The mean health status score by patients who had undergone CABG was good (x ̅ = 55.82, S.D. = 5.11). Variables that discriminated health status included age, NYHA-functional class, ejection fraction, comorbidity, knowledge of the disease, and self-care behavior. These variables predicted bad and good health status 93.3 and 96.7 percent of the time. On average, the equation of discriminate factors helped predict correct results 95.8 percent of the time. Conclusion: The discriminate factors identified can help in designing programs to develop knowledge and self-care behavior by patients who have undergone CABG.
