Abstract
Study Aim: To describe the profile and selected outcomes of CABG patients
admitted in the Cape metropolitan area. Design: A prospective descriptive study
design with a multicentre observational approach was followed. Method: All
patients undergoing isolated CABG surgery, whether elective or emergency,
during a three-month period (15 August–15 November 2005) were included in the
study. Demographic data, pre-operative medical status, intra-operative, as well as
post-operative information were collected using a self-designed structured initial
assessment form (SIA). Means and standard deviations were calculated where
applicable. Relationships between different variables were analyzed by means of:
ANOVA, correlations, linear and logistic regressions. Where it appeared that the
ANOVA assumptions were violated, non-parametric bootstrap techniques were
employed. Results: Two hundred and forty five patients were admitted to the
seven hospitals which provide CABG surgery in the Cape metropolitan area in
the allotted period. The profile of patients admitted to private and state institutions
were similar. The mean age of the sample was 60 (±10). The mean LOS of the
total cohort was 12 (±5.5) days, with patients in the state hospitals staying longer
13.4 days (± 7.1). Patients who were older than 60 were twice as likely to have a
LOS >12days (odds ratio = 2.49; 95% confidence interval = 1.33 to 4.65). The
development of a pleural effusion or pneumothorax was associated with an
increased LOS (p<0.01). At least one PPC was reported in 65% of the
population. A mortality rate of only 3% was reported. Conclusion: Patients in this
cohort were younger than in developed countries. An age greater than 60 years
was a predictor of an LOS >12days in the current cohort. Patients were most
likely to develop a PPC on day three after CABG surgery. Physiotherapeutic
intervention, 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 the
development of PPCs is also advised.
