RESUMO
BACKGROUND: The majority of patients undergoing stem cell transplantation (SCT) require a blood transfusion until the complete engraftment. Because blood transfusion rules for patients with ABO-incompatible SCT are complicated, we developed an ABO-incompatible transfusion management system (ABO-ITMS) for accurate blood transfusion and improved manageability. METHODS: A committee composed of medical doctors, technicians, and a programmer developed ABO-ITMS during the eight months from July 2013 to February 2014. The program has been linked with other databases, including clinical and laboratory databases and resulted in a new subsystem of the health information system. Server computer's operating system was Window Server 2008, and the database manager program was Oracle 11g. Programming language was ASP.Net (VBScript, C #), and the server and client computer were used to connect to the web server using a web browser. RESULTS: ABO-ITMS was designed to follow three main steps by hematologic oncology clinic, laboratory physician, and blood bank. In the first step, a hematologic-oncology clinic doctor inputs SCT recipients' data and appropriate ABO group for each phase of post-transplantation. Laboratory physician enters the isoagglutinin titer and ABO group at the second step. Finally, blood bank workers enter the results of type, screening, and antibody identification. The patient's SCT information and the previous immunohematologic test results are shown on the screen. CONCLUSION: ABO-ITMS can replace the existing complicated system and workflow. ABO-ITMS will contribute to reducing medical error and improving quality of SCT recipient care.
