Key result
Preoperative delirium in elderly patients undergoing hip surgery was associated with significantly higher odds of 30-day postoperative delirium (OR 9.38; 95% CI 7.94-11.14) and mortality.
Why the study?
Delirium frequently complicates hip fractures in elderly patients and is linked to morbidity and mortality, but associations between preoperative delirium and postoperative outcomes were understudied.
Does preoperative delirium increase the risk of adverse 30-day postoperative outcomes in elderly patients undergoing hip surgery for hip fracture?
Population
8,466 elderly patients undergoing hip surgery for hip fracture
Comparison
Preoperative delirium vs no preoperative delirium
Design
Multivariable logistic regression observational study
Follow-up
30 days

Supports preoperative delirium screening in elderly hip surgery patients; leaves open whether interventions reduce postoperative delirium or mortality.

Does preoperative delirium increase the risk of adverse 30-day postoperative outcomes in elderly patients undergoing hip surgery for hip fracture?
Odds Ratio: 9.38 (95% CI 7.94–11.14)
Preoperative delirium is a strong predictor of adverse 30-day postoperative outcomes, including mortality and postoperative delirium, in elderly patients undergoing hip fracture surgery.
Agrawal et al. (2019) conducted an observational in Hip fracture (n=8,466). Preoperative delirium vs. No preoperative delirium was evaluated on 30-day postoperative delirium (OR 9.38, 95% CI 7.94-11.14). Preoperative delirium in elderly patients undergoing hip surgery was associated with significantly higher odds of 30-day postoperative delirium (OR 9.38; 95% CI 7.94-11.14) and mortality.
