From what I read 13 less serious cases were placed in a field hospital at Sahlgrenska as a "trial run" to test the facilities, but since there is available room at in the actual hospital (and people complained) this has now stopped.

There is still available intensive care space at ordinary hospitals and it looks like the number of people needing intensive care has stabilized [1]. The latest numbers are 1072 total intensive care units (not counting field hospitals) and 528 people treated for covid-19 in intensive care [2].
