CAN THE C-REACTIVE PROTEIN TO ALBUMIN RATIO PREDICT MORTALITY DUE TO HEMIARTHROPLASTY PERFORMED AFTER HIP FRACTURE IN THE ELDERLY POPULATION?

摘要

Introduction: Hip fractures are a vital mortality and morbidity problem in the elderly population. This study investigates the role of the c-reactive protein/ albumin ratio in mortality after hip fractures. Materials and Method: The records of 144 patients ages 65 years and older who underwent hemiarthroplasty for hip fractures between 2015 and 2018 were retrospectively analyzed. Patients" records included age, gender, fracture type, American Society of Anesthesiologists score, the time between fracture and surgery, the time between surgery and discharge, length of hospital stay, preexisting comorbidities, preoperative c-reactive protein and albumin levels, and mortality. Results: The median age of the patients was 79 years (range: 65?101). Regarding sex, 89 patients (61.8%) were female, and 55 patients (38.2%) were male. Based on the univariate analysis, age, comorbidity ≥ 3, American Society of Anesthesiologists score ≥ 4, the time between fracture and surgery ≥ 2 days, the time between surgery and discharge ≥ 5 days, c-reactive protein ≥ 79 mg/L, albumin 2.85 g/dL, and c-reactive protein/albumin ratio ≥ 29 were found to be risk factors for mortality. Based on the binary logistic regression analysis, age ≥ 85 years, comorbidity ≥ 3, and c-reactive protein/albumin ratio ? 29 were independent predictors of mortality. Conclusion: C-reactive protein/albumin ratio ≥ 29 was a reliable indicator of mortality in elderly patients who underwent hemiarthroplasty for hip fractures. Additionally, being over the age of 85 and having three or more comorbidities was associated with an increased mortality risk.
