MEDITECH 6.0 1) Blood Type Dictionary - Allow Emergency Issue This prompt determines which compatibility checks are performed during Emergency Issue. It works in conjunction with the Allow Mismatch Override prompt in the Customer Defined Parameters. If you wish to have the system check product compatibility from page 2 of the Blood Type Dictionary when using the Emergency Issue routine, enter Y. If a patient does not have a historical blood type, then any unit can be emergency issued with no warning regardless of the definition of the Allow Emergency Issue prompt. If a patient does have a historical blood type and: Allow Emergency Issue = Y Allow Mismatch Override = Y All blood types can be emergency issued but the blood types will be checked for compatibility based on page two of the Blood Type Dictionary. Depending on compatibility, one of two messages will invoke: "Patient and Unit Blood Types do NOT MATCH, but are Product Compatible, OK?" or "Patient and Unit Blood Types do NOT MATCH, OK?" This action is recorded in the BBK Override Warning Report. If a patient does have a historical blood type and: Allow Emergency Issue = N Allow Mismatch Override = Y All blood types will be checked for compatibility. If the unit is product compatible, the unit can be emergency issued. If the unit is not product compatible it cannot. Two warnings will appear. Patient and Unit Blood Types do NOT MATCH, but are Product Compatible, OK? and "Incompatible blood type".
