The research doesn't really support this. People without insurance are much more likely to die in the E.R. once they get there, even after controlling for relevant health factors.
I guess I can see how they could control for differential access to preventative care resulting in ER visits with worse outcomes, or dilution by people with insurance visiting the ER with less serious problems... Even how they could control for early treatment in an ambulance vs a drive in.
But I'm interested in how they controlled for hesitance to go in the first place delaying treatment? Same condition, but you spent an extra half hour deliberating before going.
