The elderly were defined as those older than 75 years.Results  Between January 1, 2005, and December 31, 2006, a total of 54 747 patients who underwent major GI tract operations were identified from the ACS-NSQIP data file. In the elderly, overall perioperative morbidity was 1.2 to 2 times higher and mortality was 2.9 to 6.7 times higher than in younger patients after adjusting for differences in preoperative comorbidities. Irrespective of procedure type, the elderly were significantly more likely to experience cardiac (acute myocardial infarction and cardiac arrest), pulmonary (pneumonia, pulmonary embolism, and respiratory failure), and urologic (urinary tract infection and renal failure) complications. However, surgical site infections, postoperative bleeding events, deep venous thromboses, and rates of return to the operating room did not differ significantly by age.Conclusions  Morbidity and mortality are markedly higher in older patients. Quality measures for the elderly currently address only myocardial infarction, surgical site infection, and deep venous thrombosis. If care for the elderly is to be improved, quality improvement initiatives need to be expanded to include postoperative pulmonary and renal complications.
