Objective: Peripheral neuropathic pain (PNP) represents a major public health issue. Severe or refractory cases warrant tertiary multidisciplinary management, but little information is available about real-life care pathways. The primary objective of this cross-sectional, observational study was to investigate the pathways of patients with PNP consulting for the first time or followed for less than 1 year in French tertiary specialized pain clinics.
Methods: PNP was diagnosed with the NeuPSIG algorithm. Data collected included demographics, pain characteristics, and details of management before and after the study visit (e.g., drug and non-drug treatment, nature of medical visits), as well as time to referral to a pain clinic and time to a diagnosis of PNP. Factors associated with delayed referral or diagnosis were analyzed with multivariate analysis.
Results: A total of 404 patients with PNP (age 55.8 ± 15.6 years, 60.3% females, 78.3% retired or unemployed, pain duration 43.4 ± 68.9 months) were enrolled by 84 pain specialists. Pain affected mainly the lower limbs (53.5%) and was predominantly related to surgery or trauma (59.4%). Primary care management was characterized by a high proportion of conventional analgesics (60.7%). Time to referral to a pain clinic was 43.4 ± 68.9 months since pain onset and 20.1 ± 39.4 months since the diagnosis of PNP. Delayed referral to a pain clinic was independently predicted by the clinical specialty of the referring doctor and by male gender.
Conclusions: This study highlights the need for accessible guidance for non-pain specialists to improve their diagnostic and management skills and for faster referral of patients with PNP to tertiary pain clinics.
