ObjectiveTo determine the incidence and associated factors of delirium in older patients admitted with hip fracture.Material And MethodEighty patients with fall-related hip fracture who admitted to orthopedics wards in Siriraj Hospital were recruited. Baseline characteristics, functional ability and cognitive status, treatment-related factors, clinical outcomes, length of stay, and direct medical cost were evaluated. Delirium was diagnosed by experienced geriatricians using DSM-IV RESULTS: Thirty-six patients (45%,) developed delirium. Hyperactive and hypoactive delirium was 24:12 patients. Preoperative and postoperative delirium was developed in 18:18 patients. Age, TMSE score on admission, modified IQCODE score, premorbid mRS, receiving NSAIDs around the clock postoperatively, and sedative drug use were significantly different between the non-delirium and delirium groups in multivariate logistic regression analysis. Patients with delirium did not have significantly higher postoperative complications, hospital length ofstay, functional status (mRS) at discharge, mortality, and direct cost of the treatment in hospital.ConclusionDelirium is common in elderly hip fracture undergoing hip repair. Age, premorbid function, dementia/cognitive impairment, NSAIDs, and sedative use were associated factors of delirium. Identifying those with high-risk factors should be routinely performed rigorously and strategies to reduce delirium incidence and severity should be planned and conducted.
