the SI-Dep platform, which contains the results of the screening tests, encounters breakdowns

Are all Covid-19 screening results correctly collected? SI-Dep, the database where health professionals enter the results of the Covid-19 tests they perform, is encountering difficulties, according to information from the World obtained from the Directorate General for Health (DGS).

The slight drop in the national incidence rate observed in recent days should therefore be observed with great caution.

According to the indicators published by Public Health France, on 1er April, the incidence rate stood at 1,446 new people declared positive for Covid-19 per 100,000 inhabitants (over seven days), compared to 1,460 the day before.

Since March 21, “several hardware failures” have affected the“network infrastructure” Assistance Publique-Hôpitaux de Paris (AP-HP), prime contractor for SI-Dep on behalf of the Ministry of Solidarity and Health. Deadlines of ” several days “ were necessary to recover the new materials.

” The last days, [les personnels de l’AP-HP] used their emergency equipment (…). They perform operations at night to disrupt production as little as possible”adds the DGS. “These various changes could, and still can, have unanticipated side effects. » The authorities specify that disturbances can take place until Thursday, April 7, a new technical operation being “planned for the night of April 5 to 6, 2022”.

Analyze trends

However, it is difficult to estimate the possible consequences of these difficulties on the data of confirmed cases: it would above all be a question of problems which, according to the teams managing the SI-Dep database, can cause, “over a period of a few minutes, a disconnection and the impossibility of connecting to the file entry portal”. Public Health France, which publishes indicators from this database every day, has not, at present, answered the questions of the World.

To assess the dynamics of the Covid epidemic, it is in any case preferable to base oneself on the results of virological tests by date of sampling (and not by date of rise), and to analyze trends rather than data. daily. In the meantime, it is recommended that pharmacies and caregivers “immediately edit the test certificate to be given to the patient when entering the result”.

This is not the first failure encountered by the database: twice in mid-August 2021, for several hours, the professionals in charge of screening were unable to fill in SI-Dep the results of antigenic tests and supervised self-tests. More recently, at the beginning of January, faced with a record number of screenings, the authorities had to increase the number of results absorbable by SI-Dep.
