Summary and Conclusion

By including a distinct CPP syndrome classification within the ICD-11, it is hoped to avoid the problems associated with previous classifications of chronic pain when the etiology is unclear, but the emotional distress and functional disability associated with such pain are very evident, as the Global Burden of Disease project has reported.[57] The availability of 6 classes of chronic secondary pain syndromes in the same classification will facilitate the distinction of pain as a disease or long-term condition from pain as a symptom,[53] as already demonstrated in a pilot field trial. This classification has clear treatment and management implications: a multimodal approach that addresses the contributing psychological, social, and biological contributors is expected to lead to better outcomes for patients with CPP diagnoses of at least moderate severity, relative to unimodal interventions alone. In chronic secondary pain syndromes, there will be additional disease-specific treatment options to be considered as well. In addition, the representation of CPP in health statistics is expected to advance public policy and research.
