That's a CFR study, it reports how likely a detected infection is to result in death. It's intended to measure how effectively a nation's health care system treated infections.
Total per-capita covid deaths in Sweden covid are indeed about 3x those in Denmark, and closer to 5-6x those in Norwan & Finland. Sweden did a little bit better than the USA (about 50% higher still), but not relative to its neighbors:
At times, yeah. The closer you get to capacity the more the staff are overworked, the more likely you are to be attached to the old/cranky/unreliable ventilator, the more likely you are to be seen by fill-in staff pulled from other departments, the more likely it is that your hospital will run out of some medication and have to substitute, etc...
So all other things being equal, you'd expect CFRs to rise with case load. Probably not linearly, but measurably.
