An analysis of more than 240,000 cases in a national database determined seven independent preoperative risk factors that increase morbidity and mortality risk following ambulatory surgery. The factors were disseminated cancer, paraplegia or quadriplegia, age 70 or older, steroid use, kidney failure, chronic obstructive pulmonary disease and history of transient ischemic attack or stroke. Surgical site infection and intraoperative blood transfusion were among the most common complications. The findings may help improve preoperative patient screening in outpatient surgical facilities, a researcher said.
