What this trial studies

This observational study evaluates the effectiveness of the American Society of Anesthesiologists (ASA) classification and the Clinical Frailty Scale (CFS) in predicting perioperative and postoperative complications in elective surgeries for patients over 65 years old. Patients will be assessed using both classifications during preoperative examinations, and their medical histories will be reviewed after treatment to analyze outcomes. The study aims to determine which categorization better correlates with complications and length of hospital stay following surgery.

Who should consider this trial

Good fit: Ideal candidates are elective surgery patients aged 65 and older without significant mental difficulties affecting daily life.

Not a fit: Patients with earlier mental difficulties that interfere with daily life, except for those with senile dementia, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve preoperative assessments and outcomes for elderly patients undergoing elective surgeries.

How similar studies have performed: Previous studies have shown that CFS correlates with complications in emergency settings, suggesting potential for success in this novel application for elective surgeries.
