Comparison Between Different Sampling Sites for Detection of Respiratory Viruses
Switzerland501 participantsStarted 2024-12-19
Plain-language summary
The goal of this observational study is to validate the use of less invasive samples (saliva, orobuccal or nasal swabs) than nasopharyngeal swab for testing common and clinically relevant respiratory viruses in children and adults presenting to an emergency departements with symptoms compatible with respiratory tract infection. The main question it aims to answer is:
\- Is the precision of reverse transcription polymerase chain reaction (RT-PCR) for Influenzavirus A or B, respiratory syncytial virus (RSV), and Rhinovirus, on saliva, orobuccal swabs and nasal swabs comparable to the gold standard nasopharyngeal swab in a pediatric and adult population presenting with symptoms compatible with respiratory tract infection.
Among participants the following samples will be collected (nasopharyngeal swab is standard of care and not part of the study samples):
* Saliva
* Orobuccal swab
* Nasal swab

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients presenting at the emergency departments or hospitalized at Inselspital Bern university hospital with any symptom compatible with an acute respiratory tract infection in whom a nasopharyngeal swab to test for respiratory viruses is performed (standard of care)
* Written informed consent from the trial subject has been obtained; for patients aged 0-13 years, or not able to provide informed consent, consent obtained from the legal representative; for patients between 14-18 years, written informed consent obtained from the respective patient as well as the legal representative.
Exclusion Criteria:
* Patients unable to provide a saliva (e.g. patients with reduced level of consciousness). Children too young to be instructed to provide saliva are not excluded, but saliva won't be collected.
* Patients with swallowing disturbances
* Patient's lack of accountability and inability to appreciate the nature, meaning and consequences of the study and to formulate his/her own wishes correspondingly AND legal representative not available.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
