Brief Summary

Respiratory infections are very common, especially during winter, and are often caused by viruses such as influenza, SARS-CoV-2 or respiratory syncytial virus (RSV). These illnesses are generally mild, but their symptoms do not always allow a clear distinction to be made between a viral infection and a bacterial infection. In the absence of a precise diagnosis, antibiotics may be prescribed when they are not necessary in many cases. However, the excessive use of antibiotics contributes to the development of bacterial resistance, which is a major public health issue. The aim of this study is to better understand whether the use of a rapid test (called TROD), which can quickly identify certain respiratory viruses, can help doctors reduce unnecessary antibiotic prescriptions for these infections. The test will be performed using a swab gently inserted into the nose.

Outcome Measures

Primary Outcomes (1)

  • Variation in the probability of antibiotic prescription between adjacent periods differing in the use of tests TROD

    Variation in antibiotic prescription rate between 1st periods during which doctors prescribe antibiotics probabilistically without rapid diagnostic tests (TROD) as usual, followed by 2nd periods during which antibiotic prescription is guided by the results of triple TROD (SARS-CoV-2/influenza/RSV). The primary endpoint will take into account all antibiotic prescriptions received by patients within 15 days of inclusion, whether they were prescribed at the end of the consultation that led to inclusion or during follow-up consultations.

    Day 0 to Day 14

Secondary Outcomes (9)

  • Percentage of patients receiving an antibiotic prescription at the initial consultation in both groups

    Day 0

  • Percentage of patients requiring a new medical consultation between inclusion and day 14 in both groups

    Day 0 to Day 14

  • Percentage of patients requiring secondary hospitalisation between inclusion and day 14 in both groups

    Day 0 to Day 14

  • Total antibiotic consumption on day 14 in both groups

    Day 0 to Day 14

  • Total cost of patient care

    Day 0 to Day 14

  • +4 more secondary outcomes

Study Arms (2)

Interventions

TRODDIAGNOSTIC_TEST

Patient with triplex TROD test. Doctors may or may not prescribe antibiotics with the help of the results of triplex TROD tests.
