Understanding the factors that contribute to the similarities and differences in SARS-CoV-2 testing strategies across Europe
Abstract Background Since the beginning of the COVID-19 outbreak, the importance of testing suspected cases has been stressed by various governments and international organizations. Early in the pandemic, the WHO's Secretary General emphasized the need to ‘test, test, test'. Nonetheless, there were some evident differences between European Member States' testing strategies. In order to get an understanding of why and how these differences developed we conducted a mixed methods study in several EU member states. Methods We conducted semi-structured interviews with 11 professionals with expertise in public health, laboratory diagnostics and policymaking in 8 European countries, namely Croatia, Italy, Latvia, Malta, the Netherlands, Spain, Latvia, Italy, Slovenia. Based on interview results, a questionnaire is developed to quantify to which degree a larger audience of public health, laboratory and policy-making professionals believe identified factors played a role in the national SARS-CoV-2 testing strategy. Preliminary results 3 factors seem to play an important role in the diagnostic capacity and testing strategy. Firstly, differences in the countries' available stockpile and their ability to efficiently procure diagnostic equipment influenced testing strategies. Secondly, the variation in institutions that took ownership of the issues of developing, executing and developing the policies led to differences in the testing strategies. Lastly, all countries aimed to follow international advice and guidelines, which led to the convergence of testing strategies over time. Conclusions In order to be prepared for a pandemic of COVID-19's scale and make necessary adjustments in capacity building, it is important that Member States understand the factors that play an important role in both their own and other European countries' diagnostic preparedness strategies.
