. To describe the profile and selected outcomes of coronary artery bypass graft (CABG) patients admitted to both private and public hospitals in the Cape metropolitan area.

. A prospective descriptive study design with a multi-centre observational approach was followed.
. Only patients undergoing isolated CABG surgery were included in the study. Demographic data, preoperative medical status, and intra-operative and postoperative information were collected using a self-designed structured initial assessment tool. Relationships between different variables were analysed by means of analysis of variance (ANOVA), correlations, linear and logistic regressions.
. 245 patients were admitted to the seven hospitals that provide CABG surgery in the Cape metropolitan area. The mean age of the sample was 60 (±10) years. The mean length of stay (LOS) of the total cohort was 12.1 (±5.5) days, with patients in the state hospitals staying longer (13.4 (±7.1) days) than private patients (11.7 (±4.8) days). Patients aged ≥60 years were twice as likely to have a LOS >12 days (odds ratio 2.49; 95% confidence interval 1.33 - 4.65). The development of a pleural effusion or pneumothorax was associated with an increased LOS (p<0.01). At least one postoperative pulmonary complication (PPC) was reported in 65% of the population.
. Patients in this cohort were younger than in developed countries. Age≥60 years was a predictor of LOS of more than 12 days. Patients were most likely to develop a PPC on day 3 after CABG surgery.
