This study evaluated the outcome of patients in a pediatric intensive care unit (ICU) of a developing country applying Pediatric Index of Mortality (PIM) version-2 scoring system. A total of 163 consecutive patients were prospectively studied. Data included demographics, diagnoses at admission, PIM-2 score, the duration of ICU stay and hospital outcome. Predicted mortality and standardized mortality ratio (SMR) were calculated. Respiratory and neurological illnesses were the main admission diagnoses. The mean length of stay was 5.4 [95% Confidence Intervals (CI): 4–6.9] days. The mean predicted mortality was 6.2% (95% CI: 4.3–8.1); the observed mortality rate was 5.5%, the SMR being 0.89. Hosmer–Lemeshow analysis calibrated PIM-2 for the case mix [χ2 = 5.64 (df = 7), p = 0.58]. The area under the ROC curve was 0.82 (95% CI: 0.72–0.92) showing a good discriminant function. Performance of the pediatric ICU in Barbados is comparable to that of developed world by risk-adjusted outcome evaluation.
