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.
