Objective
To access the potential health impact on the population during mass gathering over
time using labelling procedure in emergency department (ED).

Introduction
The massive flow of people to mass gathering events, such as festivals or sports
events like EURO 2016, may increase public health risks. In the particular context
of several terrorist attacks that took place in France in 2015, the French national
Public Health agency has decided to strengthen the population health surveillance
systems using the mandatory notification disease system and the French national
syndromic surveillance SurSaUD®.

The objectives in terms of health surveillance of mass gathering are: 1/ the timely
detection of a health event (infectious cluster, environmental exposure, collective
foodborne disease…) 2/ the health impact assessment of an unexpected event
such as a terrorist attack.

In collaboration with the Regional Emergency Observatory (ORU), a procedure for the
labeling of emergencies has been tested to identify the ED records that could be
considered as linked to the event.

Methods
During summer 2016, the procedure was tested on seven major festive events throughout
the region. In addition to the main medical diagnosis, a specific ICD-10 code
“Y3388” was chosen to be used in associated diagnosis for records that
were supposed to linked to the event.

Information on the labeling procedure was insured by the ORU to the emergency
departments.

All records with medical diagnoses or medical pattern beginning by Y33 have been
analyzed.

Results
No significant increase in the global indicator was observed in the ED impacted by
mass gathering. The ED labelling procedure identified 260 records: two thirds
corresponded to young men and 17% came from abroad. Among the 250 records labeled in
associated diagnosis, 39% were associated to traumatisms and 31% corresponded to
alcohol intake.

Conclusions
This study shows that a labelling procedure allows the identification, quantification
and characterization of the population ED records associated with mass gathering.
Additionally, a labelling procedure to assess a potential impact of an event as mass
gathering can be implemented fairly rapidly.
