It that were the case, you would expect the danger to come towards the end of shifts and not from the changeover itself or beginning of new shifts. The problem is the passing of information. Some places operate on a 12 hour schedule and some on an 8 hour schedule. It isn't clear that the 8 hour schedule is actually safer because while workers are less tired, you increasing the number of daily handovers by 50%.
>Higher more people, overlap shifts, problem solved.
Sure, sometimes the solution is to just throw more money at the problem. However that doesn't mean the money is available to dedicate to that solution.
If the problem is money, they should just say so. The "but the outcomes" talk is still a lie.
Also US healthcare is so grossly inefficient it doesn't make sense to look at one cost center in isolation from a policy perspective, only from a the perspective of private sector actors I think shouldn't exist.
