Abstract

Background : Reduction of the turnaround time of laboratory tests including blood collection and patient data input into computer is an essential step for improvement of laboratory services. We have evaluated some working situations for blood collection and patient data input into computer to find the best way to reduce the turnaround time in
the first step of laboratory tests.
Methods : The time required for blood collection including waiting time and the time for patient data input into computer were recorded at five different situations consisting of various combinations of phlebotomists, a guide and a computer system with barcode labeling. The data were analyzed by Student’s T-test and SAS program.
Results : A significant reduction of blood collection time was achieved by adding of one more phlebotomist rather than by adding of a guide, by adding the barcode system only, or by adding a clerk and the barcode system. The time for computer input of patient’s information was remarkably reduced to one-fourth by the introduction of
barcode system.
Conclusions : The introduction of barcode system into blood collection process could not bring a reduction of turnarround time in bolld collection however adding a phlebotomist brought a significant reduction of the time. The barcode system was only effective in a computer input of patient’s information.
