The profile and selected outcomes of coronary artery bypass graft (CABG) patients in the Cape Metropolitan Area :a baseline study

[摘要] Study Aim: To describe the profile and selected outcomes of CABG patientsadmitted in the Cape metropolitan area. Design: A prospective descriptive studydesign with a multicentre observational approach was followed. Method: Allpatients undergoing isolated CABG surgery, whether elective or emergency,during a three-month period (15 August–15 November 2005) were included in thestudy. Demographic data, pre-operative medical status, intra-operative, as well aspost-operative information were collected using a self-designed structured initialassessment form (SIA). Means and standard deviations were calculated whereapplicable. Relationships between different variables were analyzed by means of:ANOVA, correlations, linear and logistic regressions. Where it appeared that theANOVA assumptions were violated, non-parametric bootstrap techniques wereemployed. Results: Two hundred and forty five patients were admitted to theseven hospitals which provide CABG surgery in the Cape metropolitan area inthe allotted period. The profile of patients admitted to private and state institutionswere similar. The mean age of the sample was 60 (±10). The mean LOS of thetotal cohort was 12 (±5.5) days, with patients in the state hospitals staying longer13.4 days (± 7.1). Patients who were older than 60 were twice as likely to have aLOS >12days (odds ratio = 2.49; 95% confidence interval = 1.33 to 4.65). Thedevelopment of a pleural effusion or pneumothorax was associated with anincreased LOS (p<0.01). At least one PPC was reported in 65% of thepopulation. A mortality rate of only 3% was reported. Conclusion: Patients in thiscohort were younger than in developed countries. An age greater than 60 yearswas a predictor of an LOS >12days in the current cohort. Patients were mostlikely to develop a PPC on day three after CABG surgery. Physiotherapeuticintervention, if any, would be well aimed at those patients older than 60 years of age. Screening of patients in the first three post-operative days for thedevelopment of PPCs is also advised.
