Introduction: Chronic pain is a very debilitating and underestimated condition, affecting patients’ quality of life. Its prevalence is around 20% in adult European population and about 36.7% in Portugal adult population. Neuropathic pain represents about 7% - 8% of all chronic pain conditions in Europe and accounts for more depression, anxiety and sleep disorders than any other type of pain. For this reason, chronic neuropathic pain is now considered as a common public health problem with a major impact on health related costs.Objectives: To understand patients’ satisfaction regarding topical treatment with lidocaine patches in some clinical conditions of neuropathic localized chronic pain.Methods: A telephone survey of 6 questions specifically designed for this study was applied to all the patients followed in consultation for chronic neuropathic pain to whom lidocaine patches were recommended. This retrospective study took place in Hospital de Braga, at the Physical and Rehabilitation Medicine Service, between December 2015 and December 2016.Results: Fifty two patients in such conditions were identified, but only 31 were included (27 women and 4 men). Four groups were then formed, according to diagnosis or consultation purpose: Pain after surgical intervention (n=21), peripheral canal syndromes (n=3), post-herpetic neuralgia (n=1) and Morton neuroma (n=6). Twenty four patients (77%) were satisfied with the recommended treatment with lidocaine patches, with post-herpetic neuralgia attending for the biggest score for pain relief (50%), followed by pain after surgical intervention group (47% in pain relief). Eighteen out of 31 patients also tried other therapeutic options, including pharmacological or physiotherapy.Conclusion: Despite some limitations of this study, such as small simple size and heterogeneity between the groups, most of the patients felt satisfied with lidocaine patches treatment. This study enhances the potential of using lidocaine patches in different contexts of localized neuropathic pain other than Post-herpetic Neuralgia. The authors suggest, however, the need for more clinical studies to sustainably propose treatment with lidocaine patches in localized neuropathic pain.
