Abstract
Background
Chronic primary pain (CPP) is one of seven diagnostic groups within the proposed classification of chronic pain in ICD‐11. Our aims were to apply the proposed ICD‐11 criteria in a large cohort of chronic pain patients participating in the Chronic Pain Self‐Management Program (CPSMP) and further investigate whether participants with CPP differed from participants with chronic secondary pain (CSP) regarding health, health expenditure, and the effect of participating in the CPSMP.
Methods
A secondary analysis of a randomized, controlled trial on the effect of the CPSMP. Four examiners categorized participants’ pain according to ICD‐11 using register‐based medical diagnoses and patients’ self‐reported symptoms. Afterwards, differences between CPP and CSP were examined.
Results
Out of 394 participants, 312 were successfully classified into CPP (n=164) or CSP (n=148) whereas 76 had a mixed pain condition. Participants with CPP were younger, more likely to be women, and had a longer pain duration compared to participants with CSP. Participants with CPP reported worse health‐related quality of life on the SF‐36 Mental Component Summary and subscales of vitality, social functioning, and bodily pain. Participants with CSP had more physical comorbidities and higher total health expenditure. None of the groups benefitted from the CPSMP.
Conclusions
We successfully applied the new classification of chronic pain in ICD‐11 on the basis of ICD‐10 medical diagnoses and symptom self‐report. Participants with CPP differed significantly from participants with CSP on baseline characteristics, self‐reported health measures, and total health expenditure. The CPSMP was not effective in any of the groups.
