PEREZ, C. et al. Expert consensus about the clinical use of topical treatments for the management of peripheral neuropathic pain. Rev. Soc. Esp. Dolor [online]. 2013, vol.20, n.6, pp.308-323. ISSN 1134-8046.  https://dx.doi.org/10.4321/S1134-80462013000600005.

Objective: To propose consensus from a panel of state level that integrates clinical experience and the most current evidence, recommendations on the clinical use of topical treatments for the management of peripheral neuropathic pain (PNP). Methods: We propose, based on a literature review on topical therapeutic options in PNP, a series of professional standards and clinical recommendations for improving the use of these topical agents. We used the modified Delphi method in two rounds to contrast the views of a national panel of 52 renowned experts, selected by a "snowball" strategy among the group of anesthesiologists pain units (94 %) and other specialists (neurologist and trauma). We evaluated 61 clinical recommendations grouped into 6 areas: a) PNP systemic versus topical treatment (11 items); b) postsurgical neuropathic pain, post-traumatic and painful stumps (12 items); c) post-herpetic neuralgia, intercostal and trigeminal (9 items); d) PNP entrapment (8 items); e) CRPS (11 items); and f) diabetic neuropathy (DN) and other polyneuropathy (HIV, alcohol, toxicity, etc.) (10 items). We used a Likert-type ordinal scale of 9 points (disagree/agree) to evaluate each recommendation. After the first round of the survey, information was provided requested to reconsider the vote on items not agree. Results: After the first round the panel consensus was achieved in 37 of the 61 issues raised. At the end of the second round of the agreement amounted to 46 (75 %). In general, there was consensus among experts on whether to introduce topical treatment in first line treatment of PNP and its greater acceptance by patients compared with systemic. He was also a shared view consider in the management of various types of PNP. Also reached a high level of agreement to accept, from a physiological point of view, the indication for treatment with capsaicin patch 8 % for various types of PNP. Conclusions: Experts in the clinical management of PNP show a high level of professional agreement with various therapeutic recommendations for study. The dissemination of such recommendations can help improving the routine management of topical drugs for neuropathic pain in our health system.
