AIM: Analysing the effectiveness of a surgical procedure is mandatory in every modern health-care system. The aging of the population stresses the need for a good standard of care. This study tests the hypothesis that porthsmouth-physiologic operative severity score for enumeration of morbidity and mortality (P-POSSUM) and colorectal-POSSUM (CR-POSSUM) would be useful clinical auditing tools in colorectal cancer surgery for aged patients. METHOD: One hundred and seventy-seven consecutive patients over 70 years of age underwent emergency or elective surgery from January 2003 to December 2005. Demographic, clinical and surgical information, score systems' prediction, complications and 30-day mortality data were prospectively entered in a comprehensive database. The observed over expected morbidity and mortality rate was calculated. RESULTS: Thirty-day observed mortality was 10.3% (19/177) while P-POSSUM and CR-POSSUM expected mortality were, respectively, 11.21% (P = NS) and 13.08% (P = NS). Overall observed morbidity was 42.7%, P-POSSUM prediction was 59.3% (P = 0.002). Morbidity and mortality data were analysed for specific subgroups of patients (resection and anastomosis/resection and stoma/palliative; emergency/elective). CONCLUSION: P-POSSUM and CR-POSSUM are useful tools to predict mortality in elderly patients. P-POSSUM significantly overestimated the risk of complications. A more accurate tool for preoperative assessment for aged patients is probably needed to predict the post-surgical outcome.
