A team at Johns Hopkins Medicine has developed a blood management system called the maximum surgical blood order schedule system. MSBOS is an update to a system introduced in the late 1970s, and it is based on blood utilization data from anesthesia information management systems. The system can be used to reduce unnecessary blood orders and has the potential to save the medical center more than $200,000 annually, and it can be adapted by other hospitals with computerized anesthesia records, a researcher said.
