Overview
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.
Description
The study aims to identify the risk factors of CPSP three months after surgery and subsequently develop a risk index to identify high-risk patients considering the multifactorial etiology of CPSP.
A comprehensive entry pool was derived from a systematic literature search. Data collection will record parameters at four different time points: preoperative assessment (60 to 1 day before the scheduled procedure); evaluation of the perioperative period; postoperative period (from the third month after the operation).
The outcome variable is the presence of CPSP assessed 3 months postoperatively and defined as a mean pain intensity of at least 3 on the NRS (one-dimensional pain scale from 0 to 10) over the past three days and pain localized to the field surgical (or to the area of the lesion) projected into the innervation territory of a nerve located in this area, or referred to a dermatome.
Four separate forecasting models will be developed using data derived from surveys carried out at relevant time points for the development of the risk index.
