Frailty Assessment of Patients With Gastrointestinal Surgery

Study Overview
=================
Brief Summary
-----------------
Patients aged 65 or older under gastrointestinal surgery will be enrolled，the investigators will assess the frailty of these patients by Frailty Index Scale and explore the correlation between the frailty and perioperative adverse events.

Detailed Description
-----------------
Patients will be assessed by specially trained doctors or nurses after admission, including daily living ability, physiological function, social-psychological status, comorbidities, mental state, grip strength, walking speed. After the assessment, the patients' frailty index was obtained. Moreover, the operation time, intraoperative bleeding loss, perioperative complications, length of stay, hospitalization expenses, readmission rate within 30 days, mortality within 30 days and other outcome indicators of these patients will be recorded. The Main purposes of present study are to verify the feasibility of applying Frailty Index (FI) to assess the degree of frailty in elderly patients undergoing gastrointestinal surgery, compare the difference of perioperative adverse events in elderly patients with different degrees of frailty，find potential indicators for evaluating and predicting the safety of surgery in elderly patients, and provide reference data for the determination of future assessment tools of frailty. The secondary objective is to compare the quality of life and long-term prognosis(only for patients with cancers,including recurrence free survival and overall survival) of elderly patients with different degrees of frailty after gastrointestinal surgery.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
