Burden of Influenza at Emergency Department Level : BIED

Seasonal influenza surveillance in France relies on several sources to detect the onset of the epidemic early, as well as to estimate the severity of epidemics and their impact on the health system. However, the data collected do not fully measure the impact of epidemics on the hospital system.

Increasing the investigator's knowledge of the impact of influenza on the hospital system, particularly on emergencies, which are the most affected service, is essential to better adapt the resources put in place to care for patients.

The study will allow a better understanding of the influenza burden, by systematically documenting the severe events (i.e. requiring consultations to the Emergency Rooms) that are triggered by influenza but not necessarily reported/recorded as influenza.

Treatment and study plan

Nasal Swab

Other

Patient included in emergency with a nasal swab

Primary outcomes

  1. Proportion of laboratory confirmed influenza among patients admitted to Emergency Room during the influenza season

    Time frame: 1 day (at admission)

    The proportion of laboratory confirmed influenza cases will be calculated by dividing the number of patients with laboratory confirmed influenza by the total number of patients included

Secondary outcomes

  1. Proportion of patients with co-morbidities

    Time frame: 1 day (at admission)

    to evaluate the proportion of patients consulting emergency department who have co-morbidities according to the result of the virological sampling

  2. Proportion of patients with laboratory confirmed influenza and related outcomes

    Time frame: 1 day (at admission)

    to estimate the proportion of patients with a laboratory confirmed influenza stratified on the emergency department visit outcomes (hospitalization in medicine, hospitalization in intensive care unit or return home) and other covariates

  3. Proportion of patients who consult for other causes than influenza

    Time frame: 1 day (at admission)

    to estimate the proportion of patients with a laboratory confirmed influenza consulting for other causes than influenza

  4. Proportion of asymptomatic influenza cases among patients with laboratory confirmed influenza

    Time frame: 1 day (at admission)

    The proportion asymptomatic influenza cases will be calculated by dividing the number of patients with asymptomatic influenza by the total number of laboratory confirmed influenza
