Brief Summary
The goal of this observational study is to identify the risk factors of Chronic Postoperative pain (or Chronic Post Surgery Pain - CPSP) three months after surgery and, subsequently. the development of a risk index to identify high-risk patients considering the multifactorial etiology of CPOP in adult patients undergoing any type of elective surgery.

Outcome Measures
Primary Outcomes (1)
Chronic Post Surgery Pain (CPSP)
Presence of CPSP assessed 3 months after surgery and defined as an average pain intensity of at least 3 points on the NRS scale (one-dimensional pain scale - from 0 to 10 points) in the last three days and pain localized to the surgical field (or in the lesion area) projected into the innervation territory of a nerve located in this area, or referred to a dermatome.
3 months
Secondary Outcomes (4)
Pre operative factors
60 to 1 day before the scheduled procedure
Perioperative factors - before surgery
The day of the scheduled surgery - before the surgery
Perioperative factors - after surgery
Immediately after the surgery to 48 hours after the surgery
Post operative factors
3 months after surgery
Other Outcomes (1)
Development of the risk index
6 months after the primary completion of the study
Study Arms (1)
Surgery Patients
Data collection will record parameters of patients undergoing surgery at four different times: preoperative assessment (60 to 1 day before the scheduled procedure); evaluation of the perioperative period; and postoperative period (from the third month following surgery).
Interventions
The outcome variable is the presence of CPSP assessed 3 months after surgery and defined as an average pain intensity of at least 3 on the NRS scale (11-point one-dimensional pain scale) in the last three days, and pain localized to the surgical field (or in the lesion area) projected into the innervation territory of a nerve located in this area or referred to a dermatome. Separate prediction models will be developed using data derived from surveys conducted at the relevant time points for the development of the risk index.
