In this post, I present the case that U.S. News & World Report’s patient safety score, a component of its annual Best Hospitals rankings, has a bias against Maryland hospitals. Two editors at U.S. News respond to my position at the bottom of the post.

Yet when those reports come out, we still scrutinize them, seeking to understand how to improve. This work is only worthwhile, of course, when these rankings are based on valid measures.
