Development of a Secondary Order Program for Pretransfusion Tests to Improve the Work Efficiency of Blood Bank / 대한수혈학회지

ABSTRACT

Background@#In the author’s blood bank, if the Ab screening test results are positive in the pretransfusion test, an Ab identification test and polyspecific direct antiglobulin test (DAT) are performed. IgG and C3 monospecific DATs are also performed if the polyspecific DAT is positive. To perform additional tests, clinical technologists used to communicate with the clinical department by telephone, and then the clinical doctor issued the orders.There could be problems with this process, such as clerical errors and reduced work efficiency. Therefore, this study developed the secondary order program to improve the work efficiency of the blood bank. @*Methods@#The secondary order program that allows the laboratory medicine doctors to issue additional test orders, print out barcodes in blood bank, and immediately report the results to the EMR (Electronic Medical Record) was developed. Before (Jul 2018∼Jun 2019) and after (Jul 2019∼Jun 2020) applying the program to inpatients, the number of telephone calls, Ab screening tests, Ab identification tests, polyspecific DAT, and monospecific DAT were compared to evaluate the effectiveness of the program. @*Results@#After applying the program, 515 calls per year (average 43 calls per month) were reduced. Before the program, the results of 68 Ab screening tests and 16 polyspecific DATs were not reported on EMR, but no case was missed after the program. @*Conclusion@#Through the secondary order program, the work efficiency of the blood bank was improved. It is expected that expanding this program to other blood bank tests will help implement tests faster and make them more systematic.
