1) Free time-saver perks for all hospital staff. I'm talking cleaners to the houses, pre-cooked take-home family meals, the whole nine yards.
2) Temporarily lower the threshold for trained medical professionals. There are many students and immigrants with plenty of education and skills. Get them in hospitals until we reach the point where it becomes a space issue rather than a staffing one. Give more experienced staff priority pick on working hours. Stem the bleeding and stop the work exhaustion/burnout.
3) Start longer term efforts to ramp up training of medical professionals. It's only gonna get worse with the baby boomers retiring and needing their own care.
4) Tell "big insurance" and "big healthcare" to put up or shut up. Slap on metrics and quotas focused on efficiency and net outcomes. Tweak the metrics until they get the picture. Set the bars high enough that the majority of issues are solved if the bar is met. If they can't meet the bar, hit their pocket books until they go bankrupt, nationalize them, then convert to single payer.
