Do you know that it would have been a shorter wait time during a period where the hospital wasn't overwhelmed? If so, how much shorter? Perhaps the medical staff were able to tell the signs of ectopic pregnancy in a way that allowed them put your wife lower on the triage priority list than you thought she should have been.
Does your area have any sort of restrictions? If not, how would the amount of time you had to wait be changed in a world where your area did have restrictions?
Even if you can show some benefit from the restrictions, are the benefits great enough to be worthwhile given the costs?
