ABSTRACT
During the first wave of the COVID-19 pandemic, there was a shortage of SARS-CoV-2 diagnostic tests, and testing patients with mild symptoms (low-threshold testing) was not recommended in the Netherlands. Despite these guidelines, to protect those who were most at risk, low-threshold testing was advocated and offered to the majority of long-term care institutions in the Twente region. In this manner, 144 healthcare workers and 96 residents tested SARS-CoV-2-positive and were isolated before the same service was provided nationwide by public health services. Strikingly, excess mortality rate in the Twente region 1 month after the introduction of this strategy was found to be 62%-89% lower than that in neighboring regions, which may be explained by this divergent testing strategy. In an emerging pandemic, early implementation of a liberal testing policy may be more effective than restricted testing in settings with a high death rate.
