This study will collect perioperative pain-related data of elderly patients in multi-centers. Analyzing these collected data to find the high-risk factors of postoperative pain in elderly patients and to establish an early-warning model of perioperative pain in elderly patients, so as to improve the ability of assessing the risks of postoperative pain in elderly patients and providing an early warning.
This study will collect perioperative pain-related data of elderly patients in multi-centers, including: preoperative general data, intraoperative anesthesia and surgical data, clinical laboratory data, postoperative pain and intervention, postoperative complications and quality of life. Analyzing these collected data to find the high-risk factors of postoperative pain in elderly patients and to establish an early-warning model of perioperative pain in elderly patients, so as to improve the ability of assessing the risks of postoperative pain in elderly patients and providing an early warning.

RECRUITINGPain trajectories after surgery
The pain trajectory is the vector of mean pain severity domain score (from 0 to 10) measured with pain severity domain of the Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R)
Time frame: within 6 months
Pain trajectories after surgery
The pain trajectory is the vector of mean pain severity domain score (from 0 to 10) measured with Brief Pain Inventory -Short Form (BPI-SF) within 6 months
Time frame: within 6 months
Outcome of 6-mins-walking test
Walking distance of 6 minutes
Time frame: 1, 3, 7, 14, 21, 30, 60, 90, 120, 150 and180 days postoperation
Postoperative duration of stay in hospital
The duration when patients stay in hospital after surgery.
Time frame: 30 days postoperation
Number of readmission within 30 days after surgery
Readmission indicates unplanned readmission after hospital discharge.
Time frame: Up to 30 days postoperation
Complications within 30 days after surgery
Complications within 30 days after surgery will be classified using Clavien-Dindo Classification of Surgical Complications, ranging from Grade I(Any deviation from the normal postoperative course without the need for pharmacological treatment or surgical, endoscopic and radiological interventions) to Grade V(death of a patient).
Time frame: Up to 30 days postoperation
The trajectories of health related quality of life(HRQoL)
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The trajectory of HRQoL is the vector of Utility values measured with EuroQol five-dimensional questionnaire(EQ-5D)taken over 6 months(days 1, 3, 7,14, 21, 30, 60, 90, 120, 150,180; Day 0 is the day of surgery). The EQ-5D measures health on five domains (mobility, self-care, usual activities, pain discomfort, and anxiety-depression), and the scores will be combined using Chinese general population weights to generate a single utility or index score. Utility values for the EQ-5D range from 1.00 to -0.391, where a score of 0 and 1 are regarded as equivalent to death and 'perfect health', respectively, and a score \< 0 is considered as health state that is 'worse than death'.
Time frame: 1, 3, 7, 14, 21, 30, 60, 90, 120, 150 and180 days postoperation
Ambulation time
The first time when patients can get off of bed and walk after surgery
Time frame: Up to 30 days postoperation
Oral feeding time
The first time when patients begin oral feeding after surgery
Time frame: Up to 30 days postoperation
