Very interesting report from Reuters:

Catholic and other church-owned systems are significantly more likely to provide higher quality performance and efficiency to the communities served than investor-owned systems, according to a Thomson Reuters analysis of the quality performance of 255 health systems in the United States.Catholic health systems are also significantly more likely to provide higher quality performance to the communities served than secular not-for-profit health systems, it said. By contrast, investor-owned systems have significantly lower performance than all other groups.

I'd never seen any similar side-by-side comparisons, and this seems to me to be about the strongest argument I've seen for keeping Catholic hospitals going.
