So. There’s this thing called HAIBA. It is the danish Hospital-Acquired Infections database.
The database is built on the proud danish tradition of databasing everything, it works by crossreferencing the national patient registry (LPR) and the national microbiological database (MiBa). LPR provides times of admission to hospital and transfers between departments. MiBa provides samples taken and sample results from clinical microbiology labs.
The database is great, and it is not so great.
