The use of LIS for blood usage review. Experience in a children's hospital.

To comply with the requirements of the Joint Commission for the Accreditation of Healthcare Organizations (JCAHO) and to facilitate the review process, the authors designed a program to screen for the appropriateness of packed red cell (PRC) and platelet concentrate (PLT) transfusions. The purpose of this report is to describe the methodology of the review process. A quality assurance (QA) monitor was created in the Laboratory Information System (LIS) to screen indicators: hemoglobin for PRCs and platelet count for PLTs. Numerical value limits were defined to determine acceptable ranges. Each week, the LIS compiles a list of all patients who received transfusions and for whom the QA monitor determined that the values of the screened indicators were outside the defined appropriate limits. A detailed transfusion record is generated for each patient identified. During a six-month evaluation of this program, a total of 1,788 PRC and 3,109 PLT units were transfused. Of these, 582 PRC (32.5%) and 2,219 PLT (71.4%) units were within the acceptable guidelines. Lists for the remaining 1,206 PRCs and 890 PLTs were generated. Review of the transfusion record and other laboratory values from the LIS established the appropriateness of 1,052 PRC and 782 PLT transfusions. At the conclusion of the six-month period, the medical charts for 181 (11%) PRC and 108 (4.5%) PLT transfusions required chart review. This method provided major reduction in time of the transfusion review process. Similar guidelines may be used to monitor other transfusion products such as fresh frozen plasma.
