Prospective evaluation of preoperative cognitive impairment and postoperative morbidity in geriatric patients undergoing emergency general surgery

Background: Cognitive impairment (CI) is common in geriatric patients. We aimed to evaluate the prevalence and impact of CI on outcomes in geriatric patients undergoing emergency general surgery (EGS). Methods: We performed a (2017-2018) prospective analysis of patients (age >= 65y) who underwent EGS. Cognition was assessed using the Montreal Cognitive Assessment (MoCA). Patients were stratified into: CI (MoCA score<26) and no-CI (MoCA >= 26). Outcomes were the prevalence of CI, in-hospital complications, discharged to rehab/skilled nursing facility (SNF), and mortality. Results: A total of 142 patients were enrolled. Overall prevalence of CI was 20%. Patients with CI had higher rates of complications (OR 1.6 [1.4-1.9]; p = 0.01), and discharge to rehab/SNF (OR 2.2 [2.0-2.5]; p = 0.03). There was no difference in mortality (OR 1.1 [0.6-1.8]; p = 0.24) between the 2 groups. Conclusion: One in five geriatric EGS patients has CI. It is associated with higher complications and adverse discharge. Cognitive assessment should be included in preoperative risk stratification. (C) 2020 Elsevier Inc. All rights reserved.
