Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

With the progression of population aging, the number of elderly patients undergoing surgery is increasing as well. However, as the condition of health differs greatly between individual elderly patients even of the same age, it is a necessity to evaluate elderly patients thoroughly and individually for better management of perioperative care.

Frailty is a condition in which patients are impaired at physical reserve and homeostatic control. Frail elderly people are at higher risk of morbidity and mortality after exposure to a stressor. Frail patients are at higher risk of perioperative complications and longer hospital stay. However, there has been no standard criteria or tool to evaluate frailty in the elderly. Neither has there been enough evidence explaining the mechanism between frailty and increased perioperative complications. Therefore, in this study we aim to discover the relationship between frailty and intraoperative hemodynamic instability, as well as perioperative complications in the elderly patients, hoping to find an adequate and practical model for preoperative assessment in the elderly hopefully for better perioperative outcome.
