MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Delirium is an acute change in mental status characterized by fluctuating disturbances of consciousness and attention. Elderly patients are prone to delirium after surgery; this contributes significantly to post-operative morbidity and can also lead to long-term disability.

Our study found that among older adults undergoing hip fracture surgery, both an increased duration of surgery and a general anesthetic are associated with an increased risk for post-operative delirium.​ 

MedicalResearch.com: What should readers take away from your report?

Response: ​Post-operative delirium is a complex problem, with many contributing factors. Longer surgical length increases the risk for delirium, in patients with hip fractures, and this association is stronger in patients that receive a general anesthetic.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Future studies, including ones we are completing, should examine the relationship between surgical length and post-operative delirium in other surgical procedures.
