You can feel how safe your hospital is, correct?  After all, working in our hospitals every day gives us a good sense of the overall level of safety and quality, right?  Well, new work suggests that the answer is absolutely not.  This fits well with a growing body of knowledge that shows how our intuition and daily experience may not line up with overall levels of quality and performance in our systems.  Now, remember,be skeptical of studies that show no difference between two things, or no effect, because that's a very easy conclusion to reach if study design, statistics, or analysis is flawed ...so we always want to be careful of studies that show how something is NOT associated or does NOT happen.  However, that said, here's yet another piece of evidence that how we think and feel about our system, based on our intuition and experience, may not line up with actual performance.  This makes rigorous, data driven tools more important than ever to show us the blind spots that our experience does not!  Although the researchers were surprised by these findings, you should not be...
