Here's a new research finding that is encouraging but discouraging at the same time for patient safety. After 16 Michigan hospitals began to share patient safety information, surgical complication rates dropped by nearly 10 percent, according to a recent study.

That's encouraging, of course. The disquieting piece is why it would take a major research study to reach such an intuitively obvious result, and why sharing of data doesn't already happen on a wide and routine scale.
