Abstract

Background:

Postoperative delirium is a frequent neuropsychiatric complication following hip surgery in older adults and is associated with prolonged hospitalization, increased morbidity, and mortality.

Objective:

To determine the incidence and preoperative risk factors of postoperative delirium following hip surgery.

Methods:

This prospective observational study included 87 adult patients undergoing hip surgery at a tertiary care center between January 2020 and December 2023. Preoperative demographic characteristics, comorbidities, neurological and psychiatric history, hemoglobin levels, and functional status were recorded. Postoperative delirium was diagnosed using ICD-10 criteria. Statistical analysis included chi-square test, independent t-test, and logistic regression analysis.

Results:

Nineteen out of 87 patients developed postoperative delirium, giving an incidence of 21.8 cases per 100 patients undergoing hip surgery. Advanced age (>70 years), male sex, dementia, Parkinson’s disease, psychiatric illness, and poor functional status were significantly associated with delirium (p < 0.001). Mean hospital stay was longer in the delirium group (15±2 days) compared to the non-delirium group (9±2 days; p<0.001).

Conclusion:

Postoperative delirium is common after hip surgery and is strongly associated with preexisting neurological disease and functional dependence.
