The current database is composed of 1 124 237 files ollected throughout 24 years (from 1994 to 2017) from 256 maternity units (around 60 maternity units each year)
These files are transmitted by the maternity units by Internet, floppy disc or in paper form when the maternity units are waiting for computerisation. They are subject to a validation procedure before being pooled.
All data are anonymous. Any nominative information about patients appears in the database
The centralised file is subject to a complete statistical study thanks to the SAS system (variables description, crossing of variables, selection of subgroups and analysis). The results are diffused in a booklet at the end of each year and in Internet
