Prognostic value of neutrophil/lymphocyte and platelet/lymphocyte ratios in predicting one year mortality in patients with hip fractures patients over 60 years old

Objective
In this study, we have aimed to determine the effect of Neutrophil/lymphocyte rate (NLR) and Platelet/lymphocyte ratio (PLR) on one-year mortality in patients over 60 years old with hip fracture.
Methods
S72.00, S72.10, and S72.20 codes were screened according to International Classification of Disease-10 (ICD-10) and 560 patients were included as cases of hip fracture. Admission blood counts and clinical data were obtained from medical data. The predictors of one-year mortality were evaluated.
Results
One hundred sixteen out of 560 patients (20.7%) included in the study died during one-year follow-up. When comparison characteristics of patients according to one-year mortality of patients (survivor-nonsurvivor groups), significant differences were detected for age, lymphocyte, NLR, and PLR (p<0.05). When Cox regression model was created to assess the factors predicting one-year mortality, hazard ratio (HR) of NLR and PLR were 1.059 (1.022-1.097, p=0.002) and 0.997 (0.994-0999, p=0.01) respectively.
Conclusion
In the study, the values of NLR and PLR in predicting mortality among patients who were over sixty and who had hip fractures, both NLR and PLR were seen to be higher in the survivors' group than in the non-survivors' group. However, when the specifity of these values are considered, it is obvious that these values are not sufficiently reliable for clinical use
