Predictive value of prognostic nutritional index on postoperative intensive care requirement and mortality in geriatric hip fracture patients.

In geriatric hip fracture patients, preoperative PNI value can be used, like ASA status, in determining postoperative ICU requirements. Nutritional deficiencies are associated with adverse postoperative outcomes in this patient group, and low PNI values (<32.5) help predict in-hospital mortality.
