8 304 MRI in cobalamin deficiency The Application of Bar-Code in Picture Archiving and Communication System CHIH-MING FAN 1,2 CHUN-HSU YAO 2 JACKSON C-T LIN 2 GWO-HAO HO 4 HSUN-SHENG HUNG 4 SHU-HANG NG 1 Department of Radiology 1 and Department of Medical Information Administration 4, Chang Gung Memorial Hospital Department of radiological Technology 2, Chung-Tai Institute of Health Sciences and Technology Department of Medical Imaging 3, Chung Shan Medical University Hospital Bar-code system is widely utilized in our daily life. In order to assess the usefulness of the bar-code system in picture archiving and communicating system (), we used bar-code reader as the complementary tool of for registration, radiographic taking, and imaging reporting in the department of the diagnostic radiology. Our hospital has just accomplished with bar-code system for the Health Care Center, Intensive Care Unit and Emergency Department. The working flow of our computer radiography (CR) is currently more complicate than that of the conventional radiography. It requires registry, printing registry sheet, selecting the items of the procedure from the work-list and seting imaging parameter in the CR ID terminal, taking radiography, reading imaging by CR reader, imaging quality assurance, transporting images to the, printing images, and film interpretation. In this study, we used bar code in for the purposes to reduce the workload and the keyboard input error of technologists, and to facilitate radiologists to interpret the images on viewers by rapid retrieval of Hospital Information System (HIS) and the Radiology Information System (RIS). From an analysis of 102 randomized cases using key-broad to input examination information, we found that the averaged time for the routine radiologic procedures was 7 seconds, while for CT and MRI was 47 seconds. The error percentage is 2.95%. For comparison, we assessed the efficiency of bar code in retrieving medical information from 56 patients. We found that each data retrieval with bar code required only one second and the error percentage was zero. In addition, radiologists took the advantage of bar code by getting the images, clinical and radiological data simultaneously, obviating any input mistake. We concluded that bar code could enhance the efficiency of technologist and radiologist during executing.
