Which peri-operative risk scoring tool accurately calculates mortality and morbidity risk in emergency laparotomy patients?
Absolute Event Rate: 10.5% vs 10.5%
CR-POSSUM is the most accurate post-operative risk scoring tool for predicting mortality in emergency laparotomy patients, while pre-operative tools like ASA and Lee Index are inaccurate.
Stonelake et al. (2015) conducted an observational in Emergency laparotomy (n=86). Peri-operative risk scoring tools (ASA, Lee index, POSSUM, P-POSSUM, CR-POSSUM) vs. Actual mortality and morbidity was evaluated on Mortality. Post-operative risk scoring using CR-POSSUM accurately predicted the actual mortality rate of 10.5%, whereas pre-operative tools like the Lee Index under-predicted and ASA over-predicted risk.
