Study summary

Hospital-acquired influenza is associated with significant morbidity and mortality in hospitalized patients notably elderly patients. Furthermore, it is also associated with a large economic impact for the hospitals.

The transmission of influenza has been mostly reported in pediatric and long-stay units. The chains of transmission of influenza in acute-stay units have to be describe in order to prevent and control potential outbreaks. Furthermore, to know clinical symptoms seems to be important in order to identify potential sources of virus as soon as possible and to set up appropriate hygiene prevention measures. Moreover, the definition of the hospital-acquired influenza has to be harmonized for all over the studies, especially concerning the delay between the admission in the hospital and the symptoms onset.

The aim of this study is to describe the hospital-acquired influenza in a french university hospital of around 800 beds

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Feb 2018; primary completion for Jun 2018, 4 months later.

Of 56 non-industry observational studies under Cross Infection, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 65. This study's planned 4 months is below that.

Counting every sponsor, half of 56 studies reached it within 28 months; a quarter within 17 and three quarters within 65.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 30, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
