You may want to base the sanitarium facility somewhere outside of the U.S. I've heard (don't know how reliable this is) that many asylums either down sized or were shut down over time, which has the effect of having more people on the streets who lack good long term care help.

Perhaps a facility on an Island? If salt has any effect on spirits of magic, it could act as a dampening effect? It isolated the inmates from modern society, as well as helps with keeping them contained.

Just out of curiosity, might not the Catholic church run parallel facilities of their own, as they've been around for centuries, and likely have records going back far enough to establish oddities that otherwise gets swept under the rug? The question then would be, why doesn't the Church want knowledge of this nature more common if it gives people incentive to depend on the Church more?
