Evaluating predictors of mortality in octogenarians undergoing urgent or emergent trauma laparotomy

This study aimed to identify associated risk factors for mortality in octogenarian trauma patients undergoing urgent or emergent laparotomy (UEL).

Trauma patients ages 80-89 years-old undergoing UEL within 6-hours of arrival were included. A multivariable logistic regression analysis was performed to determine associated risk of mortality.

From 701 octogenarians undergoing UEL, 324 (46.2%) died. Compared to survivors, UEL octogenarians who died had higher rates of cirrhosis (3.5% vs. 1.1%, p = 0.028), injuries to the brain (17.3% vs. 5.6%, p < 0.001), heart (8.6% vs. 1.6%, p < 0.001), and lung (57.4% vs. 23.9%, p < 0.001) and lower rates of functional independence (6.4% vs. 12.6%, p = 0.007). The strongest independent associated patient-related risk factor for death was cirrhosis (OR 8.28, CI 2.25-30.46, p = 0.001). However, undergoing concurrent thoracotomy increased risk of death significantly (OR 16.59, CI 2.07-132.76, p = 0.008). Functional independence was not associated with mortality (p > 0.05).

This national analysis emphasizes the need to identify and manage pre-existing conditions like cirrhosis and not determine futility based on pre-trauma functional status alone. Concurrent thoracotomy for hemorrhage control increases risk of death over 16-fold.
