Summary

Chronic pain is a worldwide health problem due to its high prevalence and its difficult management with a significant impact on quality of life. Pain and addiction co-occur frequently. Indeed, the prevalence of addiction in patients with chronic non-cancer pain may affect from 0% to 50% of patients (Højsted et al 2010). This large variability in the estimation of addiction prevalence in chronic non-cancer pain patients is at least partly due to a lack of standardization of the selected patients from the clinical or therapeutic point of view and the lack of consensus in the use of a specific evaluation tool or gold standard. Indeed, several tools are currently available at the international level with varying efficiencies and precisions (Chou et al 2009, Turk, Swanson, and Gatchel 2008, Højsted and Sjøgren 2007). In France, no data are available on the prevalence of analgesic opioid misuse in chronic non-cancer pain patients, due to the lack clinical studies and validated tools in French.

Detailed description

This is an observational study . Each addictovigilance centre will contact Pain Clinics in order to enroll patients meeting the inclusion criteria. The questionnaires will be prepared and sent to the participating centres by the coordinating centre (Clermont-Ferrand). Participation in the study will be systematically proposed by the physician during the study inclusion period (3 months). Patients meeting all inclusion criteria will be enrolled after receiving oral information about the study. This questionnaire can be semi-directed (doctor / nurse / CRA) and will be carried out during a consultation as part of their usual care. Answering the questionnaire should take no more than 10 minutes. No additional diagnostic or monitoring procedures will be applied to patients.
