The Relationship Between Preoperative Anxiety Level and Frailty Score in Elderly Patients Scheduled for Elective Hip Arthroplasty: A Prospective Observational Study

Frailty is a state of vulnerability resulting from decreased physiological reserve across multiple organ systems, impairing an individual's ability to withstand stressors. As the elderly population grows worldwide, the proportion of older adults undergoing surgical procedures continues to rise, and frailty is expected to become increasingly prevalent among surgical candidates. Anxiety is one of the most common psychiatric conditions, affecting approximately one in three individuals globally. Preoperative anxiety may negatively influence surgical outcomes, particularly in older and more vulnerable patients. This prospective observational study aims to evaluate the relationship between preoperative anxiety level and frailty score in elderly patients aged 65 years and older scheduled for elective hip arthroplasty. Frailty will be assessed using the FRAIL Scale (Fatigue, Resistance, Ambulation, Illness, Loss of Weight), and anxiety will be measured using the Hamilton Anxiety Rating Scale (HAM-A). Secondary outcomes include the prevalence of frailty and anxiety, the effect of frailty on length of hospital stay, postoperative intensive care unit admission rates, and the relationship between frailty and preoperative laboratory and hemodynamic parameters.
