Key result
ACPGBI CRC model underestimates emergency surgery mortality compared to actual rates and p-POSSUM.
Why the study?
The ACPGBI colorectal cancer scoring system's accuracy for predicting operative mortality in emergency colorectal cancer surgery compared to p-POSSUM was uncertain.
Does the ACPGBI CRC scoring system accurately predict operative mortality compared to the p-POSSUM instrument in patients undergoing colorectal cancer surgery?
Comparison

Does the ACPGBI CRC scoring system accurately predict operative mortality compared to the p-POSSUM instrument in patients undergoing colorectal cancer surgery?
The ACPGBI CRC model significantly underestimates predicted mortality in emergency colorectal cancer surgery compared to actual outcomes and the p-POSSUM model.
Metcalfe et al. (2005) conducted an observational in colorectal cancer (n=72). ACPGBI colorectal cancer scoring system vs. p-POSSUM instrument and actual mortality was evaluated on operative mortality. The ACPGBI colorectal cancer model underestimated predicted mortality in emergency surgery compared to actual mortality and the p-POSSUM instrument.
