Kontinuierliche Überwachung von SARS-CoV-2 Infektionen in Kindertagesstätten: eine qualitative Interviewstudie über die Erfahrungen von Betreuer*innen und Eltern mit verschiedenen Testverfahren im häuslichen Umfeld

Abstract

Background

Since the beginning of the corona pandemic in Germany in January 2020, day care centres (DCC) have faced the challenge of reliably detecting cases of SARS-CoV-2 infection as early and reliably as possible in order to avoid major outbreaks and closures. Conducting regular virological screening tests for asymptomatic DCC children and childcare workers requires a high level of acceptance among participants and should be as easy as possible to implement. The present study aimed to evaluate childcare workers’ and parents’ attitudes and experiences regarding the acceptance and feasibility of various screening methods. This assessment was conducted using additional qualitative interviews designed for home-based screening in the context of a screening study in DCCs.

Method

From May to July 2021, childcare workers and parents of children in nine DCCs in Wuerzburg independently carried out screening tests for SARS-CoV-2 at home twice a week as part of the “Würzburg Child Care Study in the COVID-19 Pandemic 2.0”. The participants were offered two self-sampling methods (mouth-rinsing fluid for pooled PCR tests and/or nasal rapid antigen self-tests). Before and after the 12-week test phase, telephone interviews were conducted with a selected sample of childcare workers and parents in order to ascertain initial attitudes and further experiences with the two self-sampling methods and their implementation. The interviews were fully transcribed for analysis and subjected to a qualitative content analysis according to Kuckartz.

Results

Of the 1,026 eligible participants, 591 individuals, including 139 childcare workers and the parents of 452 children, agreed to take part in the screening tests. A total of 49 interviews were conducted with a specifically selected sample (20 before the start of the test, 29 after the end of the test). In the qualitative content analysis, three overarching topics emerged: ‘aspects of the test performance’, ‘aspects of the perception of safety’ and ‘aspects of the testing in children’. Regardless of the fact that the various test methods and test features were perceived very differently, conducting the tests at home was found to be feasible.

Discussion

The differentiated insights into the participants’ perspectives provide valuable information about factors that influence the acceptance of self-testing. These should be taken into account before such a measure is introduced in DCCs if necessary.

Conclusion

The assessment of test procedures is strongly influenced by individual preferences. Test concepts should be implemented with as little time and organisational effort as possible in order to promote willingness to participate. Clear study information and quick feedback on test results can enhance the sense of security among parents and childcare workers.
