Declarations
:
: As the study was registry-based and without patient contact, approval from an ethics committee or consent from participants is not required according to Danish law. However, because microbiology data are legally considered to be medical chart data, we needed permission to use these (Danish Patient Safety Authority, Rec. No. 3–3013-945/1 and 3–3013-945/2). The project was listed in the Region of Southern Denmark’s record (Rec. No. 24/14678).
