Study Overview
Brief Summary
Self-swabbing requires less personal protective equipment and could allow to test more people and even to do quick self-diagnosis if antigenic tests are available.
In a preliminary study on 190 medical students, the investigators have shown that self and conventional swabbing were identically well-accepted with equivalent level of pain and discomfort induced by swabbing. In a sub-group of this sample, the investigators have shown that the quality of the 2 sampling methods were equivalent.
The goal of this large study in the general population is to confirm these findings in an adequately powered study. Such results would allow to develop self-swabbing for large screening campaigns and eventually self-diagnosis using antigenic tests.
Detailed Description
All consecutive subjects coming to the 2 dedicated centers for COVID-19 screening in Clermont-Ferrand University hospital (one for medical students and one for the general population) will be asked to be included in the present study. They will be randomly assigned to either supervised self-swabbing followed by conventional swabbing led by a healthcare professional or the other way round.
All the subjects will have to complete a brief questionnaire including demographical characteristics (age, sex, height, weight, eye color), potential symptoms (asthenia, fever, anosmia...) anticipated pain and discomfort and previous nasopharyngeal swabbing experience. Pain, discomfort and overall acceptability of the procedure will be completed just after completion of the swabbing.

Arms & Interventions
Supervised self-swabbing followed by conventional swabbing
the subjects will first benefit from a 5 minutes explanation on how to perform self-swabbing and will then performed the swabbing under the supervision of a trained healthcare professional
Intervention: nasopharyngeal swabbing procedure (self swabbing first) (Other)
Conventional swabbing followed by supervised self-swabbing
the subject will undergo conventional nasopharyngeal swabbing performed by a trained healthcare professional first.
Intervention: nasopharyngeal swabbing procedure (conventionnal swabbing first) (Other)
Outcomes
Primary Outcomes
Non-inferiority of self-swabbing compared to conventional swabbing concerning diagnosis sensitivity
Time Frame: 5 minutes after the end of the procedure of nasopharyngeal swabbing
assessed using consistency of COVID-19 RT-PCR results for both sampling modalities (Self- swabbing versus conventional-swabbing). If non-inferiority is confirmed on this criterion, pain will be tested.
Secondary Outcomes
- Non-inferiority of self-swabbing compared to conventional swabbing concerning acceptability(5 minutes after the end of the procedure of nasopharyngeal swabbing)
- Correlation between body mass index and swabbing-induced pain(5 minutes after the end of the procedure)
- Non-inferiority of self-swabbing compared to conventional swabbing concerning pain(5 minutes after the end of the procedure of nasopharyngeal swabbing)
- Correlation between symptoms (fever, headache, asthenia, anosmia, agueusia, cough, dyspnea, muscle pain, sore throat, diarrhea) and swabbing-induced pain(5 minutes after the end of the procedure)
- Correlation between anticipated pain and actual pain(5 minutes after the end of the procedure)
- Correlation between anticipated discomfort and actual discomfort.(5 minutes after the end of the procedure)
- Correlation between age, sex and swabbing-induced pain(5 minutes after the end of the procedure)
- Correlation between eye color and swabbing-induced pain(5 minutes after the end of the procedure)
- Correlation between eye color and swabbing-induced discomfort(5 minutes after the end of the procedure)
- Richness assessment for respiratory cells(Day 0)
- Non-inferiority of self-swabbing compared to conventional swabbing concerning pain discomfort(5 minutes after the end of the procedure of nasopharyngeal swabbing)
