What this trial studies

This observational study aims to establish a prospective database of elderly patients undergoing elective surgery across multiple centers in China. It will collect data on various postoperative complications, including those affecting the central nervous system, cardiovascular system, kidneys, and respiratory system. The goal is to analyze the incidence and risk factors associated with perioperative morbidity and mortality in this population, ultimately developing risk assessment methods and prevention strategies to improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are geriatric surgical patients aged 65 years and older who are scheduled for elective surgery with an overnight hospital stay.

Not a fit: Patients with severe cognitive impairments, language disorders, or those undergoing cardiac surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management and outcomes for elderly surgical patients, reducing complications and mortality rates.

How similar studies have performed: While similar studies have been conducted, this approach focuses specifically on a large-scale database for elderly patients in China, making it a novel initiative.
