Objective: To explore the value of preoperative C-reactive protein(CRP)/albumin ratio (CAR) and Geriatric Nutritional Risk Index (GNRI) in the prognostic evaluation of elderly patients with hip fracture. Methods: A retrospective analysis of the clinical data of 135 elderly hip fractures treated in our department from January 2016 to January 2019. The patients were divided into poor prognosis group (n=42) and good prognosis group (n=93) according to whether they died within 1 year after operation. Multivariate Logistic regression was used to analyze the risk factors that affected the prognosis of elderly patients with hip fracture. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of CAR and GNRI for the poor prognosis of elderly patients with hip fracture. Results: Univariate analysis showed that the age, APACHEⅡ score, ASA classification, CRP, albumin, CAR and GNRI of the poor prognosis group were significantly different from those of the good prognosis group (P<0.05). Multivariate logistic regression analysis showed that age, APACHEⅡ score, ASA classification, CRP, albumin, CAR and GNRI were important risk factors for poor prognosis in elderly patients with hip fracture (P<0.05). The area under the curve for CAR, GNRI and the two combined tests to predict poor prognosis of elderly patients with hip fracture was 0.897, 0.878 and 0.952. Conclusion: Increased CAR and decreased GNRI are important risk factors for poor prognosis in elderly patients with hip fractures. The combined detection of CAR and GNRI is more valuable in predicting the poor prognosis of elderly patients with hip fractures, which can be used as a reference index for clinical evaluation of the prognosis risk of elderly patients with hip fracture after surgery. |
