Additionally, the treatment of chronic pain is often complex, with outcomes frequently falling short of expectations. As chronic pain continues to be a significant global problem affecting medical, psychological and socioeconomic aspects, and with the growing number of surgeries performed, there is a pressing need for an early, comprehensive model to predict CPSP. Various models have been created in recent years to predict postsurgical pain.
