Brief summary (from the registry)

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.

Eligibility criteria

Show eligibility criteria (verbatim from the registry)
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 Exclusion Criteria: * Patients in the central nervous system group were excluded from cardiac and neurosurgery, patients in the heart injury group were excluded from cardiac surgery, and patients who did not agree to participate in the study were excluded in all groups.
