The aim of this study was to characterize chronic non-cancer pain (CNCP) patients’ states, through an unsupervised cluster analysis, to implement clinical recommendations in pain care.Patients and Methods: Real-world ambulatory CNCP cohort of patients (n = 418) completed a multidimensional patient-reported registry, as part of a routine initial evaluation, in a multidisciplinary academic pain unit. A clustering analysis was performed according to: 1) pain intensity and relief; 2) quality of life; 3) number of adverse events; and 4) emergency department visits. A retrospective study was developed (n = 120) following the stratified analysis.Results: From a principal component analysis, cut-off points were defined to discriminate between the six clusters and three groups of different pain intervention requirements. Those patients showed a significantly different monitoring and basal clinical status. Being older than 65 years old, retired or on medical leave, under opioids and anxiolytic prescription, had a severe impact on daily quality of life without any sex-difference.Conclusion: These clusters based on real-world clinical information might be useful for screening even more where the access to physical exploration is limited. Follow-up analyses will support the replicability of this stratified care.Keywords: global pain status, chronic non-cancer pain, clustering analysis, quality of life, stratified care |
