Pre Operative Frailty Indices as Predictor of Postoperative Outcomes in Elderly Patients
Main Article Content
Abstract
Background: The growing elderly population has led to an increasing number of surgical procedures in older patients, who are at a higher risk of adverse postoperative outcomes. Chronological age alone is an unreliable predictor of surgical risk, necessitating the use of comprehensive preoperative assessment tools. Frailty, a multidimensional syndrome characterized by reduced physiological reserve, has emerged as an important predictor of postoperative morbidity and mortality.
Objectives: This study aimed to evaluate the role of preoperative frailty indices as predictors of postoperative outcomes in elderly patients undergoing surgery.
Materials and Methods: A hospital-based prospective observational study was conducted in the Department of Anesthesiology at a tertiary care hospital. A total of 95 elderly patients aged ≥60 years undergoing elective surgery were included. Preoperative frailty assessment was performed using a validated frailty index during pre-anesthetic evaluation. Postoperative outcomes assessed included complications, length of hospital stay, requirement for intensive care unit (ICU) admission, and postoperative mortality. Data were analyzed using appropriate statistical methods, with a p-value <0.05 considered statistically significant.
Results: Frail patients demonstrated a significantly higher incidence of postoperative complications, prolonged hospital stay, increased ICU admissions, and higher postoperative mortality compared to non-frail and pre-frail patients. A progressive increase in adverse outcomes was observed with worsening frailty status, indicating a strong association between preoperative frailty and postoperative outcomes.
Conclusion: Preoperative frailty assessment is a valuable tool for predicting postoperative outcomes in elderly surgical patients. Incorporation of frailty indices into routine pre-anesthetic evaluation may improve perioperative risk stratification and facilitate targeted interventions to optimize surgical outcomes in this vulnerable population.
