Abstract
To examine the influence of clinical and demographic factors on self-care behaviour and hospitalization rates among patients with coronary heart disease awaiting coronary artery bypass grafting. Appropriate self-care behaviour can improve the management of patients with coronary heart disease and reduce hospitalization rates among those awaiting coronary artery bypass graft surgery. However, little is known about the influence of clinical and demographic factors on self-care or hospitalizations in this population. A cross-sectional study. A convenience sample of 99 participants diagnosed with coronary heart disease awaiting coronary artery bypass grafting surgery were recruited from an outpatient clinic of a public tertiary hospital in southern Thailand. Data were collected on clinical (left ventricular ejection fraction, symptom severity and comorbid disease) and demographic (age, education level and marital status) factors, self-care behaviour and hospitalization rates. Path analysis using LISREL was performed to examine the influence of self-care on hospitalizations, with clinical and demographic factors as moderators. Path analysis showed that clinical and demographic factors accounted for nearly half of the variance (46%) in self-care, and that self-care accounted for nearly half of the variance (48%) in hospitalization rates. Our findings demonstrate that clinical and demographic factors play an important role in self-care behaviour, and in turn hospitalization rates of pre-coronary artery bypass graft surgery patients. It is suggested that the period pre-surgery is an ideal time to introduce programmes designed to bolster self-care and minimize uncertainty among this patient population and that nurses are well-positioned to do so. Study methods and results reported in adherence to the STROBE checklist. Patients contributed their consent, time and data to the study.
