[Prevalence of neuropathic pain in Spain: clinical, working and health care implications]

A narrative systematic medical literature review on prevalence of neuropathic pain (NP) in Spain from 1990 to 2004 was conducted. The average number of publications was 3 per year. Prevalence data varied depending on studied population, definition of pain/pathology and time of pain evolution. The most commonly studied pathologies included: mononeuropathies and polyneuropathies: 42%, multiple sclerosis: 35% and entrapment neuropathies: 16%. Some episodes of NP were left untreated. One third of patients with back pain receiving analgesic treatment still had high intensity pain. Future studies on the prevalence of NP should use work definitions and criteria reached by consensus. An awareness of the clinical presentation of NP and an appropriate and early treatment could minimize its clinical, working and health care implications. NP is a diverse and highly prevalent condition in Spain. Efforts should be conducted towards the achievement of diagnostic criteria consensus and higher rates of analgesic success.
