In 2007, the Plan for the improvement of the quality of life of people with chronic diseases stressed that support for pain was the first expectations of patient associations. And pain support is primarily the field of competence of the treating physician. It is in this context, that (HAS) recommendations were developed to promote the implementation of care tailored for people expressing a chronic pain. They advocate the support procedure: the identification and evaluation of the chronic pain in ambulatory (history, etiologic assessment, tests), the establishment of treatment or application with a specialized structure, diagnostic or therapeutic advice.
