There should be much greater regulation along with frequent inspections and a mandate that residents have information in their rooms about how to report issues directly to the government.
Those things obviously wouldn't help with the coronavirus issues at present, but having that type of government infrastructure involved with nursing homes would have put a lot of pieces in place to allow for a more consistent and coherent response when we started seeing Covid cases.
Of course we also needed PPE and testing en masse at nursing homes early on, so maybe it wouldn't have mattered anyway.
