The New York Times from yesterday has an editorial discussing hospital acquired infections: Hospitals Shouldn’t Make You Sicker – NYTimes.com. They discuss some new studies in the New England Journal of Medicine as well as some efforts by the Obama Administration. While there is a lot of research on hospital acquired infections, one thing the Times does not discuss is the fact that we know very little about the microbial ecology of hospitals. This is something that needs much much more research in my opinion.
