Background and aims: Over the years Chronic Pain has become a scourge of disability for individuals of every age who haven´t an adequate response to health care, particularly in Primary Health Care (PHC). The first step to responding this problem was the creation, in 2015, of a chronic pain consultation in PHC in the authors´ unit. The authors have made a review of available evidence to validate a chronic pain assessment protocol that can be replicated in any Primary Care Unit.
Methods: In July 2018 a bibliographic research was made through PubMed. The Mesh terms were used: ("Chronic Pain" [Mesh]) AND "Pain Measurement" [Mesh]. The authors selected the studies in duplicate, and to include them, two of three reviewers would have to be in consensus.
Results: The review showed a small number of articles published about the evaluation of Chronic Pain. Globally, the authors found that there aren´t adequate scales for PHCs. It has been verified that the most used methods of evaluation of pain are the Visual Analog Scale (VAS) and the Numerical Pain Scale (NPS). In evaluation of neuropathic pain the most used method was the DN4 questionnaire. Regarding the evaluation of anxiety and depression in these patients, the articles selected presented great disparity and it wasn´t possible to determine the best evaluation scale.
Conclusions: The protocol created based on this bibliographic research is indispensable to clinical practice because, without it, it isn´t possible to have a 360º view of the patient with pain.
