Core Tip
Core Tip: Cognitive dysfunction and preoperative depression were recognized as independent variables and were evaluated for the incidence of postoperative delirium in hip fracture surgery patients in the geriatric population. We have shown a considerable increase in the incidence of postoperative delirium with the combination of dementia and depression in this population via established techniques including the 15-item Geriatric Depression Scale, the Mini-Mental State Examination, and the Confusion Assessment Method. Higher American Society of Anesthesiologists scores and older age only increase the incidence. The incorporation of these screening mechanisms in the preoperative settings is expected to help construction of specific preoperative plans for patients at higher risk.
