Postoperative Delirium in Older Patients: A Systematic Review of Assessment and Incidence of Postoperative Delirium.

The incidence and risk factors for POD introduced can be used for future research to target these potential indicators. The incidence rate, risk factors, and predictors of POD explored can provide robust evidence for clinical practitioners in their daily practice.
