Objective: To realize a registry about aetology and costs of patients with Neuropathic Pain (NeP) in Pain Clinics (PC) in Spain. Methods: Retrospective, cross-ssectional study performed between april and december 2004 in PC. Demographic data, NeP type and cause, origin of the derivation, and health resources consumption (treatments, medical visits, hospitalizations, etc) were collected and direct medical costs were calculated in year 2004. A descriptive statistic and ANCOVA models were applied. Results: 504 NeP patients of broad aetiology (44% radiculophaty, 21% neuralgias, 11% neurophaties, 7% entrapment syndromes, 5% CRPS, 4% central pain), 57.8±0.7 years (Mean±SE), 57.6% women, and 29.6±2.2 months of evolution, were enrolled in the study. Adjusted monthly average cost was 403€ (95% CI: 333€-473€). Neuropathies present an adjusted monthly cost significantly higher than average (580+90€, p=0.011), because of the higher number of hospitalization days (0.6+0.1, p=0.021) and the higher pharmacologic cost (162+17€, p=0.001). Radiculophaties showed lower adjusted cost than the average; 287+46€, p=0.026, because of the lower cost of hospitalization; 79+38€, p=0.027. Conclusions: NeP causes a considerable utilization of health resources with a substantial cost for the National Health Service. Neurophaties are the aetiology syndrome which showed the higher monthly cost per patient, while radiculophaties showed a cost significantly lower than the average.
