Elderly patients with hip fractures exhibit a high incidence of mortality and morbidity. The aim of this study was to evaluate the factors that may predict mortality in patients with geriatric hip fracture.
Included in this retrospective study were 241 patients who were admitted to the hospital with hip fractures between May 2017 and March 2019. The effect of the modified 5-item frailty index (mFI-5) on 30-day and 1-year mortality was evaluated. In addition, admission neutrophil-to-lymphocyte ratios (NLRs) and monocyte-to-lymphocyte ratios (MLRs) were also examined.
The mFI-5 was not found to be a statistically significant predictive indicator for 30-day and 1-year mortality (P = 0.485 and P = 0.484, respectively). Chronic obstructive pulmonary disease or current pneumonia was found to increase mortality by 2.702 times (P = 0.002). The 30-day mortality rates of patients aged ≥80 years were significantly higher than those aged 65–79 years (P < 0.05). However, there was no statistical difference in the mortality rates between the age groups after 30 days postoperatively (P = 0.114). Admission NLRs and MLRs were significantly higher in the 30-day and 1-year mortality groups. The cut-off values of the admission NLRs and MLRs for 30-day mortality were calculated as 6.55 and 0.65, respectively, while the same cut-off values for 1-year mortality were calculated as 6.55 and 0.635, respectively.
Admission NLRs and MLRs are useful hematological data for the prediction of 30-day and 1-year mortality in geriatric hip fracture patients.
