About

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 chronic postsurgical pain in elderly patients and to establish an early-warning models 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.

Based on the database, the investigators intend to explore:

Perioperative risk assessment methods and early warning models for elderly patients;
Practical, safe, and effective risk prevention and control system through subsequent studies.

Full description

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 chronic postsurgical pain in elderly patients and to establish an early-warning model of chronic postsurgical pain in elderly patients, so as to improve the ability of assessing the risks of chronic postsurgical pain in elderly patients and providing an early warning.

Inclusion criteria

Diagnosis of Chronic postsurgical pain (CPSP) CPSP was made based on the guidelines of the International Society for Pain (CPSP: ICD-11) as follows: Chronic postsurgical pain is chronic pain developing or increasing in intensity after a surgical procedure and persisting beyond the healing process, i.e. at least 3 months after surgery. The pain is either localised to the surgical field, projected to the innervation territory of a nerve situated in this area, or referred to a dermatome (after surgery/injury to deep somatic or visceral tissues). Other causes of pain including infection, malignancy etc. need to be excluded as well as pain continuing from a pre-existing pain problem. Dependent on type of surgery, chronic postsurgical pain often may be neuropathic pain.
Geriatric surgical patients ≥65 years old
