Description

For allogeneic (homologous and directed) units, uses algorithm to evaluate unit phenotyping against clinically significant patient antibody, present in the LAB DATA file (#63), Antibodies Identified field (#.075), and prevents selection if the corresponding antigen is present in the unit, based on the entries in the FUNCTION FIELD file (#61.3) for that specific antibody. For allogeneic (homologous) units, uses algorithm to evaluate unit phenotyping against clinically significant patient antibody and displays warning message if the corresponding Ag is not entered in the BLOOD INVENTORY file (#65), RBC Antigen Absent field (#.05). Determines whether crossmatch result is required based on the entry in the BLOOD PRODUCT file (#66), Patient/Product Requirement field (#.09) for the specific component. If the crossmatch result is anything other than C or IG, prevents status change to assigned for subsequent issue. If the crossmatch result is IG, prevents status change to allow issue of the unit unless the initials entered match those of the user and the user also holds the appropriate security key. Releases units back to available inventory if the result entered for the crossmatch is not C or IG. Prevents selection of units not associated with the appropriate division (even autologous). Prohibits selection of autologous unit for a different patient than the patient designated in the Restricted For field (#8). Displays current information on component requests and units assigned/available for issue. If a pooled product is transfused, calculates the number of units in a pool and enters the data in the Pooled/Divided Units field (#4.4) for the pooled product which was created. Allows entry of unit specific transfusion reaction data, (i.e. type of reaction and appropriate comments). Prevents entry of future transfusion dates.

Captures appropriate data for evaluation of transfusion practices by treating specialty through a variety of different reports.
