摘要: Background The aging population of the United States results in increasing numbers surgical operations on elderly patients. This study observed related to morbidity, mortality, and their risk factors patients undergoing major operations. Study design We reviewed our institution's American College Surgeons National Surgical Quality Improvement Program database from February 24, 2002, through June 30, 2005, including standardized preoperative, intraoperative, 30-day postoperative data points. required review analysis prospectively collected data. examined patient demographics, preoperative factors, intraoperative outcomes with a focus those aged 80 years older. Results A total 7,696 procedures incurred 28% morbidity rate 2.3% mortality rate, although older than age had 51% 7%.
