Relationship between admission neutrophil/lymphocyte, thrombocyte/lymphocyte, and monocyte/lymphocyte ratios and 1-year mortality in geriatric hip fractures: Triple comparison.

Abstract

Elderly patients with hip fractures have a high post-operative 1-year mortality rate. The aim of this study was to investigate the relationship of the neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and monocyte/lymphocyte ratio (MLR) with mortality. The data of 350 patients who suffered femoral intertrochanteric fractures between January 2015 and January 2020 were examined, and the demographic data of 124 patients who met the study criteria were evaluated. During the 1-year follow-up, 92 patients (74%) who continued their lives and 32 patients (25%) who died were divided into two groups: Group 1 (survivors) and Group 2 (non-survivors). NLR, TLO, MLO, presence of comorbidities, age, sex, American Society of Anesthesiologists Physical Status Classification, length of hospital stay, fracture type, and fracture pattern values were statistically compared between the two groups. NLR, TLR, and MLR are the laboratory parameters assessed within the scope of the study. Preoperatively, the mean NLR was 6.59 (1.61-26.29), mean TLR was 197.94 (86-516), and mean MLR was 0.73 (0.19-15.68). In this study, a significant relationship was found between NLR, TLR, and MLR values and the occurrence of post-operative 1-year mortality (p=0.01). In addition, the result was significant in the correlation between these parameters. Cutoff values were found to be 7.53 for NLR, 192 for TLR, and 0.54 for MLR in receiver operator characteristic curve analysis (p<0.01). NLR, TLR, and PLR are significant predictors of 1-year mortality in patients aged over 60 years with hip fractures.
