Measuring Clinical Productivity of Anesthesiology Groups: Surgical Anesthesia at the Facility Level.

abstract：BACKGROUND:Optimal risk adjustment is a requisite precondition for monitoring quality of care and interpreting public reports of hospital outcomes. Current risk-adjustment measures have been criticized for including baseline variables that are difficult to obtain and inadequately adjusting for high-risk patients. The a...
