回答: Can you just figure out from the population vs medical school grads? 由 老中一号 于 2005-6-24, 20:19:11:

definite conclusion on most of things, mostly due to the constraints of time and resource. Therefore decisions based on such conclusions are often hard to reach. That when one needs to deal with risk.

But in this case the whole point is not to come up with a decision, it's about the truth isn't it. If it takes 3 months and $1M to get all the fact straight, then so be it. In fact I don't think it's so hard to collect these data. If a hospital is reasonably well managed, all activities can be recorded.
