The predictive value of modified frailty index and prognostic nutritional index for complications after hip replacement in the elderly
Objective To analyze the predictive value of modified frailty index(mFI)and prognostic nutritional index(PNI)in complications after hip replacement in the elderly.Methods The medical records of 163 elderly patients who underwent hip arthroplasty at the 908th Hospital of PLA Joint Logistic Support Force from July 2022 to December 2023 were retrospectively analyzed,and the occurrence of postoperative complications,including prosthesis loosening,periprosthetic fractures,and lower extremity deep venous thrombosis,was recorded.Patients were divided into complication group(n=21)and no complication group(n=142)based on the occurrence of complications,and the differences in mFI and PNI between the two groups were statistically compared.Logistic regression was used to analyze the relationship between mFI,PNI,and postoperative complications of elderly hip arthroplasty,and the receiver operating characteristic(ROC)curve was drawn to analyze the efficacy of mFI and PNI alone or in combination to predict postoperative complications of elderly hip arthroplasty.Results The mFI of the complication group was(3.41±0.26),which was higher than that of the non-complication group(1.75±0.31),and the PNI was(41.38±4.26),which was lower than that of the non-complication group(50.71±5.31),with statistically significant differences(t=22.338,7.687,P<0.05).Logistic regression analysis showed that mFI and PNI were related to the occurrence of complications after hip arthroplasty in the elderly(P<0.05).The ROC results showed that the area under the curve(AUC)of mFI and PNI combined to predict complications after hip arthroplasty in the elderly was 0.949(95%CI=0.908～0.989),which was higher than 0.898(95%CI=0.842～0.954)and 0.929(95%CI=0.889～0.970)predicted by the two groups alone.Conclusion The mFI and PNI of elderly patients with complications after hip replacement are at high and low levels,respectively.The application of mFI and PNI can effectively predict whether there are complications after hip replacement.The clinical application value is high,and it can be vigorously promoted.
