Notes: Predicted mortality was based on a validated risk-adjustment tool from the Agency for Health care Research and Quality. Patients at high predicted inpatient mortality were defined as those in the top quartile of predicted mortality. Patients at low predicted inpatient mortality were defined as those in the bottom three quartiles of predicted mortality.
