LAHIM am. After the approved "best practice" guideline was introduced to the medical staff, a blood utilization dashboard was developed that helps responsible clinical managers identify at the physician level when transfusion orders are placed contrary to the guideline. Having this information available enables the clinical manager to address the issue on a unit or with the individual physician involved. Use of this dashboard has resulted in significant reduction in the variation in transfusion ordering practices among the medical staff and a significant reduction in blood utilization, which equates to a significant reduction in costs of maintaining the blood supply, and an improvement in patient outcomes. a. What data elements must be accessed from the clinical data repository to drive the blood utilization dashboard? b. What clinical data systems might this data come from? 2. Emergency Department Wait Time According to the CMS Hospital Compare website, a local hospital's wait time in the emergency room was 37 minutes compared to the national average of 33 minutes (CMS 2015). Hospital leadership requested that a study be conducted to determine if the wait time was significantly higher than national average. a. What sort of analysis plan would be appropriate for this study? b. What are the some of the potential weaknesses of this approach
