[The Nadis cohort: 6236 HIV-infected patients followed up in French university hospitals]

The Nadis electronic medical patient record allows real time constitution of a database including the clinical, therapeutic, biological, and epidemiological features of HIV-positive patients.

Data concerning HIV-infected patients followed-up in 6 French University Hospitals was collected. Data quality was assessed on a regular basis in each center.

The 6 first University hospitals using Nadis agreed to group their data on March 15, 2004, concerning 6236 patients having consulted at least once in the previous year. Among these, 29% were female patients, 80% were under treatment on March 15, 2004, 9% were off treatment, 29% were co-infected by hepatitis B or C virus, 57% had an undetectable viral load, 15% of the treated patients were in a worrying immunovirological situation, 358 were diagnosed HIV-positive in 2003. 35% of these "new patients" were women, the mode of infection was sexual in 80%, 45% were under treatment on March 15, 04. This recent data allowed us to have an accurate assessment of this population's management in 2004.
