Understanding deaths from post-surgical complications

Death after surgery may follow a complication, but understanding which complications or co-morbidities are associated with death is challenging.

Robert Freundlich, MD, and colleagues used the National Surgical Quality Improvement Program database to determine the attributable mortality—death that could have been prevented if a complication had not occurred—of 21 common postoperative complications. The investigators analyzed records for nearly 1.2 million patients and found a complication independently associated with mortality for 20 percent of patients who died within 30 days of surgery.

They reported in the July issue of Anesthesia & Analgesia that the largest sources of attributable mortality were bleeding, respiratory failure, septic shock and renal failure. They also found that the attributable mortality of complications varied with age.
