High burnout scores: emotional exhaustion > 27; depersonalisation > 10; personal accomplishment < 33.
Interpretation of Cohen’s d estimation of effect size: very small 0.01; small 0.20; medium 0.50; large 0.80; very large 1.20; huge 2.0.
OB & CW, study of seven hospitals in the rural Overberg District and Cape Winelands District of the Western Cape (this study); N, number of subjects studied; s.d., standard deviation; 95% CI, 95% confidence interval; p, p-value for the t-test for independent samples, comparison with OB & CW study; 95% CI Diff, 95% confidence interval for the difference between mean values.
