Feasibility of an online antigen self-testing strategy for SARS-CoV-2 addressed to health care and education professionals in Catalonia (Spain). The TESTA’T-COVID Project

AbstractWe aimed to implement a pilot intervention based on offering online COVID-19 selftest kits addressed to healthcare and education professionals in Spain during the peak of the 6th wave caused by Omicron variant. Kits were ordered online and sent by mail, participants answered an online acceptability/usability survey and uploaded the picture of results. 492 participants ordered a test, 304 uploaded the picture (61.8%). Eighteen positive cases were detected (5.9%). 92.2% were satisfied/very satisfied with the intervention; and 92.5% found performing the test easy/very easy. We demonstrated that implementing online COVID-19 self-testing in schools and healthcare settings in Spain is feasible.Key findingsWe implemented a pilot intervention based on offering online COVID-19 selftest kits in Spain.We demonstrated the feasibility of the intervention during the peak of the 6th wave caused by Omicron variant.The intervention counted with high acceptability among healthcare and education professionals in Spain.Our results may contribute to define screening strategies addressed to key populations, particularly during peaks of high community transmission of SARS-CoV-2.
