Review Meta Analysis
Postoperative outcomes in older surgical patients with preoperative cognitive impairment: A systematic review and meta-analysis.
To determine the effect of cognitive impairment (CI) and dementia on adverse outcomes in older surgical patients. ⋯ Preoperative CI in older surgical patients significantly increases risk of delirium, 1-year mortality, discharge to assisted care, 30-day readmission, and postoperative complications. Dementia increases the risk of 1-year mortality. Cognitive screening in the preoperative assessment for older surgical patients may be helpful for risk stratification so that appropriate management can be implemented to mitigate adverse postoperative outcomes.
