Conditions

Addiction, Chronic Pain

Brief summary

It is described in the literature a higher prevalence of pain in patients with an addiction but there are few studies describing the pain profile of patients with use disorder. Pain has a very negative impact on the quality of life of opioid substituted patients. Improving knowledge on this point would make it possible to better guide specific care. The investigator proposes to conduct a single-center descriptive observational study using questionnaires, without changing the management of patients with chronic pain. The primary objective of the study is to determine the prevalence of chronic pain in patients with substance addiction hospitalized for addiction treatment.

Detailed description

It is described in the literature a higher prevalence of pain in patients with an addiction but there are few studies describing the pain profile of patients with use disorder. Pain has a very negative impact on the quality of life of opioid substituted patients. Improving knowledge on this point would make it possible to better guide specific care. The investigator proposes to conduct a single-center descriptive observational study using questionnaires, without changing the management of patients with chronic pain. All patients admitted to hospitalization in the addiction department of the LORIENT Hospital will be offered participation in the study. The primary objective of the study is to determine the prevalence of chronic pain in patients with substance addiction hospitalized for addiction treatment. The study will also evaluate the impact on daily activities of the presence of two chronic pathologies: chronic pain and addiction, describe the frequency of the two main psychiatric comorbidities of chronic pain: anxiety and depression, describe the different components of chronic pain in patients with substance addiction, and get information on analgesic medications.
