Key result
Preoperative cognitive impairment was a strong independent predictor of postoperative delirium (OR 4.132; 95% CI 1.831-9.324; P<0.001) in elderly patients with a hip fracture.
Population
825 elderly patients who sustained a femoral neck fracture from January 2005 to December 2015

May inform delirium risk stratification after hip fracture surgery; hypothesis-generating pending prospective validation.
Cohort (n=825)
Odds Ratio: 4.132 (95% CI 1.831–9.324)
p-value: p=<0.001
A predictive nomogram incorporating cognitive impairment, ASA class, transfusion volume, and ICU admission can help predict postoperative delirium risk in elderly hip fracture patients.
Zhang et al. (2018) conducted a cohort in elderly patients with a hip fracture (n=825). Preoperative cognitive impairment vs. No preoperative cognitive impairment was evaluated on development of postoperative delirium within 6 months of surgery (OR 4.132, 95% CI 1.831-9.324, p=<0.001). Preoperative cognitive impairment was a strong independent predictor of postoperative delirium (OR 4.132; 95% CI 1.831-9.324; P<0.001) in elderly patients with a hip fracture.
