ABSTRACT
BackgroundFollowing the SARS-CoV-2 Omicron variant spread, the use of unsupervised antigenic rapid diagnostic tests (self-tests) increased.AimThis study aimed to measure self-test uptake and factors associated with self-testing.MethodsIn this cross-sectional study from 20 January to 2 May 2022, the case series from a case-control study on factors associated with SARS-CoV-2 infection were used to analyse self-testing habits in France. A multivariable quasi-Poisson regression was used to explore the variables associated with self-testing among symptomatic cases who were not contacts of another infected individual. The control series from the same study was used as a proxy for the self-test background rate in the non-infected population of France.ResultsDuring the study period, 179,165 cases who tested positive through supervised tests were recruited. Of these, 64.7% had performed a self-test in the 3 days preceding this supervised test, of which 79,038 (68.2%) were positive. The most frequently reported reason for self-testing was the presence of symptoms (64.6%). Among symptomatic cases who were not aware of being contacts of another case, self-testing was positively associated with being female, higher education, household size, being a teacher and negatively associated with older age, not French by birth, healthcare-related work and immunosuppression. Among the control series, 12% self-tested during the 8 days preceding questionnaire filling, with temporal heterogeneity.ConclusionThe analysis showed high self-test uptake in France with some inequalities which must be addressed through education and facilitated access (cost and availability) for making it a more efficient epidemic control tool.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic introducing the mass autodiagnosis via rapid antigen testing methods, and self-tests were important for several populaces, yet with several neglected issues. In addition, hospital diagnosis was a target of many people or media, as the various COVID-19 clinical phenotypes trammel the precise emergency physicians' response. METHODS: A web-based questionnaire was disseminated through social media in the first half of August 2021 in the Greek populace, assessing the societal criticism for autodiagnosis and medical diagnosis and their issues, just before the occurrence of the fourth pandemic wave in the country. RESULTS: Two thirds of the responders characterized self-tests as unreliable and two fifths reported them dangerous. Reliability (OR 1.335; CI 0.060-0.300; p = 0.000) and danger (OR 5.068; CI 3139-8184; p = 0.000) were significant predictors for the population-based sample's volition for a self-test. Reversely, regarding medical diagnosis, half of the responders reported the lack of reliability and effectiveness in the emergency departments, which had a significant impact on willingness to visit a hospital if needed (OR 3.207; CI 1987-5182; p = 0.000 and OR 3.506; CI 2167-5670; p = 0.000). CONCLUSIONS: The importance of community-based questionnaires is highlighted for assessing people's criticism and improving the highlighted points in several topics.
ABSTRACT
OBJECTIVES: RDT and self-tests are sold in pharmacies. These are medical biology procedures that are currently reserved for biologists. Nevertheless, their use is now being reinforced by the COVID-19 pandemic. What role should the dispensing pharmacist have in relation to the patient? What role can the biologist have in this system? METHODS: A survey was carried out in pharmacies in the Auvergne-Rhône-Alpes region, as well as in Cameroon during the summer of 2020, to evaluate the use of RDT and self-tests. The answers obtained to the 10 questions were discussed after a simple statistical analysis. RESULTS: Two hundred and eighty-three pharmacies and 13 Cameroonian pharmacies participated in our survey. Pharmacists want to develop the use of RDT and self-test, but agree that training is necessary. Some tests are dispensed despite their unproven clinical usefulness. CONCLUSIONS: The delivery of TRODs and self-tests is acquired in pharmacies despite the reluctance of biologists. Pharmacists should be trained by biologists to use these tests in a relevant and appropriate manner.
