The first two studies took place during the Back to Live Congress on February 15 and Guido Weijers’ theatre performance on February 20, both in the Beatrix Theatre in Utrecht. These are so-called Type I events, located indoors and attended by visitors who behave calmly and mainly experience the event from one fixed place.
The core team for the research consists of members of the Fieldlab Events programme team, Radboudumc, Logistics Community Brabant/Breda University of Applied Sciences (LCB/BUas) and TU Delft. Further support is provided by companies such as Bureau Franken, DCM, bureau Brandeis and researchers from the Netherlands Organisation for Applied Scientific Research (TNO) and UTwente and TU Eindhoven.
In the Fieldlab Events pilots, the research aims to answer the main question: How do we limit the residual risk that events present? A risk analysis model has been developed for this, which provides an answer to this question based on the variables related to contact (frequency, time and distance).
To this end, the impact of the building blocks on the risk of transmission and the chance of being admitted to hospital is initially compared to the ’home’ situation, per hour.
The risk model demonstrates the impact that the building blocks and measures taken during the events have on the risk of transmission and hospitalisation per hour. While these risks are significantly higher at an event without measures, they are almost the same at the test event as the setting at home. The greatest impact is achieved through an access test, with added impact from intelligent design and logistics of the event and adequate ventilation or outside air.
Fieldlab Events has presented the research findings to the cabinet, which in turn asks the Outbreak Management Team (OMT) for its recommendations in response to those results.
The proposal of Fieldlab Events is that Type I events, regardless of the lockdown, can resume as soon as possible, even with a high prevalence of SARS-CoV-2, provided that the conditions of the following set of measures are met:
• Rapid test at a decentralised location, close to home
• Rapid test within maximum of 24 hours before the end of the event
• Use of an app or alternative access control for a negative test result
• Attendance of the location limited to 50% capacity, in breach of the 1.5 metre measure
• Use of group separation options based on location
• Use of a face mask during (at least) the movement phase on location
• Ventilation in accordance with building regulations
• Active communication with the visitors, before, during and after the event, in order to share relevant information and to draw attention to compliance with the measures (eg. via an app)
