UnlabelledIn all, 19-22% of the adult Danish population suffer from chronic pain - most frequently in the musculoskeletal system. Different pain management strategies depending on pain mechanism (neuropathic/nociceptive) make diagnosing the pain condition especially important.ObjectivesTo investigate whether a validated, self-administered questionnaire (PainDETECT) helps specialists and general practitioners in Denmark identify patients with neuropathic pain components (NeP).Research Design And MethodsIn a non-interventional study a sample of Danish specialists (rheumatologists and anaesthesiologists) and general practitioners used the PainDETECT questionnaire on 1322 chronic pain patients. PainDETECT was filled in by patients and scored by the physician. A PainDETECT score above 18 indicates the presence of NeP.ResultsA total of 87-95% of the included chronic pain patients (702 by specialists (mean age: 56 years) and 620 by general practitioners (mean age: 55 years)) had musculoskeletal pain. In 39-43% of these patients NeP components were present as assessed by PainDETECT (score 21.1-21.7). One-third of the 540 NeP patients (31-36%) had their pain diagnosis reclassified from a non-NeP to a predominant/mixed NeP diagnosis after use of PainDETECT.ConclusionsNeuropathic pain seems to be underdiagnosed in musculoskeletal pain conditions. Use of the PainDETECT instrument may be of help to general practitioners and specialists when diagnosing NeP in chronic pain patients. However, the fact that no neurologists were included, together with the limited sample size, with large variations in the number of patients each physician included, as well as the lack of a strict consecutive recruitment process are study limitations.
