What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

In addition to SarsCov2, the main viral respiratory risks are associated with influenza viruses, respiratory syncytial virus (RSV), human metapneumovirus (hMPV) parainfluenza virus (PIV), adenovirus, rhinovirus, coronavirus and others. HMPV is a respiratory virus discovered in 2001. Like RSV, it appears to be a threat in terms of morbidity and mortality in susceptible populations. Overall, viral infections can cause significant functional decline in older patients, with 67% and 25% reported to be at least temporarily housebound or bedridden, respectively. Respiratory viral infections prevent older patients from functioning and performing their daily tasks. They therefore have a significant impact on the older patients and their families. In addition, respiratory viruses are key factors in the exacerbation of chronic diseases. The aims of this study are to provide a better understanding of the role of hMPV compared to common respiratory viruses on morbimortality, risk of dependency, quality of life alteration in older inpatients.
