Introduction: Older adults experience higher rates of complications after an emergency exploratory laparotomy (EEL). To better understand the shift to an aging population in the United States, identifying how age may influence these complications in older patients is important. The current standard age category for older adult patients is ≥65. We analyzed postlaparotomy complications using a lower age split.
Methods: A retrospective analysis was done on patients who required an EEL from October 2015 to December 2019 at an academic medical center. Patient demographics and hospital course variables were collected. Differences in complications in patients aged ≥/<55 y and ≥/<65 y were measured using univariate and multivariable analyses.
Results: A total of 481 patients were reviewed. Both patient groups of ≥55 and ≥65 were typically male, White, had 3+ comorbidities, Medicare insurance, were retired, and presented in extremis to the emergency department. Patients aged ≥55 y had significant rates of pulmonary complications and inpatient mortality (odds ratio 2.2, 2.7, respectively). Patients aged ≥65 y had significant rates of genitourinary and cardiac complications (odds ratio 2.3, 1.8, respectively).
Conclusions: Patients aged ≥55 y undergoing EEL had higher odds of experiencing pulmonary complications and death during their index hospitalizations, which was not present with the standard ≥/<65-y-old patient analysis. Those aged ≥65 y experienced index genitourinary and cardiac complications. The ≥/<55 age split has a unique set of complications that should be considered. Given the increased odds of inpatient mortality and types of complications in patients aged ≥55 y, the current age split for older adults should be reconsidered.
