To my way of thinking, the best alternative for a hospital that wishes to remain true to it's Catholic values while facing this kind of dilemma is to not offer OB/GYN services in the first place.
First of all, it's a financial liability. I bet you would find that the states that require so-called "emergency contraceptives" are also those that are most generous with malpractice awards.
Second, I have to question what Catholic mission is being achieved by having an OB/GYN section in the first place? In truth, I'm wondering if there is a Catholic mission to be found in having hospitals in the U.S. at all circa 2005, but I find this to be particularly true with the OB/GYN field. If it's a charity issue to make sure that poor women can get necessary care, you can pay another organization to provide only those services you're willing to subsidize. You don't have to be a service provider to see that services are provided.
At a certain point, it really is time to 'shake the dust from your sandals'.
That's an interesting point. If Catholic hospitals (and medical practices in general) were offering Ob/Gyn services in a manner consistent with Catholic doctrine, that would be a real difference from other health care providers, and worth the Church's effort, in my opinion. However, I don't think that's the case, generally.
From my understanding, his hospital doesn't even offer delivery services due to state regulations.
