Key result
CR-POSSUM provided a better estimate of mortality risk than P-POSSUM for patients undergoing colorectal resection, predicting 25 deaths (P=0.13) compared to 29 deaths (P=0.002) against 22 observed.
Cohort (n=321)

CR-POSSUM may better estimate mortality after colorectal resection; hypothesis-generating and requires prospective validation before practice change.
Tez et al. (2006) conducted a cohort in colorectal cancer (n=321). CR-POSSUM score vs. P-POSSUM score was evaluated on mortality (chi2 = 12.20, p=0.13). CR-POSSUM provided a better estimate of mortality risk than P-POSSUM for patients undergoing colorectal resection, predicting 25 deaths (P=0.13) compared to 29 deaths (P=0.002) against 22 observed.
