Description

Since 2004, the French syndromic surveillance system SurSaUD® coordinated by the French Public Health Agency (Sante publique France) daily collects morbidity data from two data sources: the emergency departments (ED) network Oscour® and the emergency general practitioners associations SOS Medecins. Almost 92% of the French ED attendances are recorded by the system. SOS Medecins network is a group of 62 associations of general practitioners, dispatched all over the territory. Sante publique France received data from 61 out of 62 associations. Both data sources collect medical diagnosis, using ICD10 codes in the ED network and specific medical thesaurus in SOS Medecins associations. These data are routinely analyzed to detect and follow-up various expected or unusual public health events all over the territory. The system is also used for reassurance of decision makers. In that framework, in March 2017, the French Ministry of Health requested Sante publique France to validate a potential scarlet fever outbreak in France.

Objective:

Describe a case study of validation of a scarlet fever outbreak using syndromic surveillance data sources.

Description

The syndromic surveillance SurSaUD® system developed by Sante© publique France, the French National Public Health Agency collects daily data from 4 data sources: emergency departments (OSCOUR® ED network), emergency general practioners (SOS Medecins network), crude mortality (civil status data) and electronic death certification including causes of death. The system aims to timely identify, follow and assess the health impact of unusual or seasonal events on emergency medical activity and mortality. However some information could be missed by the system especially for non-severe (absence of ED consultation) or, in contrast, highly severe purposes (direct access to intensive care units). The French pre-hospital emergency medical service (SAMU) represents a potential valuable data source to complete the SurSaUD® surveillance system, thanks to reactive pre-hospital data collection and a large geographical coverage on the whole territory. Data are still not completely standardized and computerized but a governmental project to develop a national common IT system involving all French SAMU is in progress and will be experimented in the following years.

Objective:

To evaluate whether SAMU data could be relevant for health surveillance and proposed to be integrated into the French national syndromic surveillance SurSaUD® system.

Description

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.

Objective:

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

Description

After the major impact of the 2003 heat wave, France needed a reactive, permanent and national surveillance system enabling to detect and to follow-up various public health events all over the territory including overseas. In June 2004, the French syndromic surveillance system based on the emergency department (ED) has been implemented by the national institute for public health surveillance (InVS). Beginning with 23 ED in 2004, the network has progressively included new ED and several steps have contributed to accelerate this permanent increase. A first evaluation of this data source was conducted for the specific surveillance of heat wave.

Objective

Implemented 10 years ago, the French emergency department surveillance system (Oscour Network) has been assessed using four major evaluation criteria in syndromic surveillance: stability, coverage, data quality and utility.

Description

Two major heat waves occurred in France in July 2015. A first episode characterized by early onset, intensity, large geographical coverage and duration occurred between 29th of June 8th of July. A second episode less intense was localized on the South-East of the country from 15th to 23rd of July.

The French heat warning system has been operating by InVS since 2004 as part of the French National Heat Wave Plan. Warnings are based on meteorological forecasts and on real-time follow-up of specific health indicators to support decision-making. The evolutions in emergency health care facilities during the July heat waves are presented.

Objective

To present the evolution of heat-related pathologies during heat waves occurring in July 2015 in France

Since the terrorist attacks against the satirical newspaper Charlie Hebdo in January 2015, France has activated the highest level of its national anti-terrorist security plan. A new terrorist attack occurred the 26th of June at 9:50 AM in a gas production plant located in the industrial area of Saint Quentin Fallavier nearby Lyon (East -South-of France). The plant produces several different chemical products like gas and plastics and employed 40 people. The attack resulted in an explosion followed by fire. The French Institute for Public Health Surveillance (InVS) was alerted at 11 AM and decided to implement with its Rhône-Alpes regional office a protocol to timely assess the potential health impact on the population living or working around the attack area on emergency health care facilities (EHCF).

Objective

To timely assess the potential health impact on the population living or working in a terrorist attack area using syndromic surveillance

Description

In December 2013, an emergence of chikungunya was observed in the French Caribbean region. Starting on the Saint-Martin island, the epidemic of chikungunya spread in Martinique on December 2013. The first cases were then observed in Guadeloupe in December 2013 and in January 2014 in the French Guyana. A specific surveillance system has been implemented based on a sentinel general practitioners’ network enabling the estimation of the number of cases clinically suggestive. Severity of this arbovirus is assessed using the number of hospitalized cases. The syndromic surveillance system SurSaUD, based on the daily collection of two complementary morbidity data sources, is also implemented in these territories and has contributed to the surveillance of this outbreak.

Objective

Description of the temporal pattern of the chikungunya epidemic and the characteristics of patients in the French overseas territories of Americas using the French syndromic surveillance system SurSaUD.

Description

In June 2004, the French syndromic surveillance system based on the ED has been implemented by the French institute for public health surveillance (InVS), starting with 23 ED. In August 2014, about 600 ED (40,000 daily attendances) are included in the Oscour network, recording 80% of the national total attendances.

Asthma is one of the about 60 syndromic indicators monitored each day and followed all over the year.

This indicator presents important fluctuations and can be influenced by several environmental and infectious but also societal factors. Particularly factors like air pollution are known to have both short and long term impact on asthma while thunderstorms are associated with acute outbreaks of asthma.

Objective

Description of the temporal pattern of the daily number of attendances in emergency departments (ED) for asthma in Paris area and identification of the main factors influencing this indicator.

Description

Since 2004, the French syndromic surveillance system Oscour® has been implemented by the national institute for public health surveillance (InVS) and is daily used to detect and follow-up various public health events all over the territory [1]. Beginning with 23 ED in 2004, the coverage and data quality have permanently been increasing until including about 650 ED in August 2015. Initially based on a voluntary participation of ED, a mandatory transmission has been decided in July 2013, with major modification on the structural organization of the data transmission in some regions and on coding practices of the new ED. Besides this juridical context, the system is based on automatically data collection by ED physicians without recording added information for public health surveillance. This represents the main theorical condition to ensure stability and quality, even in case of occurrence of major public health events susceptible to drastically increase the workload [2].

Objective

Identification of the main factors influencing the stability and the quality of the French Emergency departments (ED) syndromic surveillance system.

Description

While the link between excess winter mortality and winter respiratory diseases in the elderly is well described, the impact of the epidemic of influenza in the elderly is mainly assessed in France through specific surveillance in the general population. Syndromic surveillance data enables to monitor ED attendances and hospitalizations for various diagnostic codes groupings throughout the influenza epidemic, some of which often cited as influenza proxies, such as cardiorespiratory diagnostic groups.

In mainland France, the 2014-15 season was characterized by an intense influenza epidemic in the community (sub-type A(H3N2) dominant virus). Hospital overcrowding was early reported, partly linked to serious clinical presentations among the elderly, and leading to the triggering of a national emergency plan.

We hypothesized that ED numbers of clinical influenza cases underestimate the influenza burden among patients aged 65 years and over, especially when a A(H3N2) influenza subtype circulates.

Objective

To estimate the real burden of influenza epidemic on emergency departments (ED) attendances and hospitalizations among patients over 65 years in order to better understand determinants of overcrowding and mortality excess.
