Using data from the Pays de la Loire surveillance program of musculoskeletal disorders and National Health Insurance system, we revealed a decreasing time trend for carpal tunnel syndrome (CTS) over an 8-year period. These decreasing trends were statistically significant for surgical cases of CTS and uncompensated work-related CTS, but not for CTS compensated as an occupational disease, while the variation in clinically diagnosed CTS among the COSALI cohort was not statistically significant.

ObjectiveTo IntroductionSOS Médecins France (SOS Med) is the first private and permanent network of general practitioners providing emergency care in France. Besides Hospital emergency departments (HED), SOS Med is therefore a major source of data for detecting and measuring nearreal-time health phenomena. The emergency services provided by the SOS Med have been subject to important changes in the recent years. Their services are enriched by a medical consultation center together with extended working hours. Besides, the south of the region is markedly affected by a declining number of medical practitioners This study was conducted to analyze the regional population coverage of emergency healthcare data provided by HED and SOS Med to the French syndromic surveillance system (SurSaUD®) taking into account distance, health care offer, demographic factors and ecological deprivation factors.
