Dr Tamer Ertan and colleagues from Turkey evaluated the predictive accuracy of different scoring systems on patients undergoing emergency colorectal surgery.

The team applied the Acute Physiology, and Chronic Health Evaluation II or III, the Simplified Acute Physiology Score II, and the Mortality Probability Model II.
The researchers also applied the Colo-rectal POSSUM scoring systems to 102 patients who underwent colorectal resection for cancer.
Validation of scoring systems was tested by assessing calibration.
Discrimination was tested using Hosmer-Lemeshow goodness-of-fit test, and the corresponding calibration curves.
Evaluation of the discriminative capability of both models was performed using receiver-operating characteristic curve analysis.
The researchers found that overall, 17 deaths occurred.
The Simplified Acute Physiology Score II showed good calibration, and discrimination.
Dr Ertans' team concluded, "These data suggest that the Simplified Acute Physiology Score II scoring system was accurate in predicting outcome for patients undergoing emergency colorectal surgery."
