Usually LIS(Laboratory Information System) depend on OCS(Order Communication System) of HIS(Hospital Information System). So, both systems are constructed simultaneously. But it needs high cost and has potential of failure. So, we designed one combined laboratory request slip and isolated LIS(sever: Power Mac 7200, eight clients: LC 475, connected by Ethernet) operating with own order input system before HIS construction. we analyzed the efficiency during early 9 weeks (from Aug. 17 to Oct. 17 in 1995) and later 4 weeks (March in 1996). Daily input amount of request changed stably in the later period(maximum: 552. mean: 410.0) than the early period(maximum: 604. mean: 341.6). Peak time was between 9 a.m. and 10 a.m.(maximum: 127. slip/hour). In the later period, 64.2% the requests for in-patients were completed until 10 a.m. and the request for out-patients distributed more evenly. Majority of problems occurred, were delayed(25.5% in the early, 61.1% in the later period) or missed specimen(31.9% in the early, 22.9% in the later). Total number (26,309) of used requests was less than half of the calculated number(57,621) of previous laboratory slips.

BACKGROUND: When it comes to wasting blood components, it usually means wastage before transfusion due to several reasons such as improvement of the patient's condition, death of the patient, delay of blood returning, etc. Yet blood components can sometimes can be wasted after a transfusion is started and this is referred as residual blood wastage. In this study, we analyzed the rate and causes of discarded blood components that are not used and the residual blood wastage in order to help reduce the rate of blood component wastage. METHODS: From January 2009 to December 2010, the number of and the reasons for discarded blood components without use and residual blood wastage were analyzed by reviewing the laboratory information system and wastage statements at Soonchunhyang University Seoul Hospital. RESULTS: The number of blood components issued during the study period was 24,001 units. Among them, the number of units discarded without use was 162 units (0.7%) and the number of units of residual blood wastage was 115 units (0.5%). Among the reasons for the discarded blood component without use, improvement of the patient's conditions ranked as 1st with 80 units (49.5%) and death of the patient ranked as 2nd with 42 units (25.9%). The biggest reason for the residual blood wastage was transfusion-related side effects with as many as 52 units (45.2%). Other than side effects, the wastage of residue from pediatric transfusion were 48 units (41.7%), followed by delay of surgery with 5 units (4.3%) and patients' refusal with 4 units (3.5%). CONCLUSION: The wastage of residue from pediatric transfusion was the second most common cause of residual blood wastage in our hospital. According to this, we should evaluate the routine use of pediatric transfusion bags and their cost-effectiveness in our hospital.

It may be difficult to establish laboratory information system(LIS) on radioimmunoassay works, which may result in many technical problems on computerization. Recently we have developed integrated information system in the radioimmunoassay works of endocrine laboratory in Kyung Hee Medical center. We have used VAX-6510 with 64 MB main memory and VAX-6210 with 32 MB main memory (DEC; Digital Equipment INC) which are main computers of the hospital. Additional devices were only 4 terminals and 4 printers in the laboratory and the office. This system has measurably changed the allocation of technologists' time and effort, the number of the clerical support staff in the laboratory and the speed and accuracy of laboratory response. And physicians could easily obtain and compare the patients' current and past laboratory results with computerization. In this article we have focused on experience gained in the automation of radioimmunoassay works of endocrine laboratory. The authors suggest that this computerized system of endocrine laboratory could provide a progressive approach to total LIS and it could serve as a model for other hospitals.

BACKGROUND: Clinical laboratories are selecting total solutions to point-of-care test (POCT) by handling all aspects of information management ranging from the ordering of the test to the reporting of verified results. Today, many POCT devices can be directly connected to the laboratory information system (LIS) via data management system (DMS). We report here our experience with the networking of POCT glucometers. METHODS: We set up computerization of POCT glucometer (Precision PCx, Abbott, USA) in August, 2004 and established a quality control (QC) system for the portable glucometers on 16 wards in Chung-Ang University Hospital. Precision of the glucometers was assessed by performing 28 replicate tests using quality control specimens containing 5 different glucose concentrations. Turnaround time (TAT) was calculated from the data of 17,796 glucose tests performed during a 5-month period in 2004 before computerization of the glucometers and 31,513 tests performed during the same 5-month period of 2005 after computerization. RESULTS: In the precision study, within-run and total-run CVs were within 10%. With the networking of POCT glucometers, the TAT from the collection of specimen to the specimen receipt to the LIS was 28.5+/-17.2 min compared to 43.6+/-17.5 without the networking (P<0.0001). A staff satisfaction survey received a high score (88%) for an overall satisfaction. CONCLUSIONS: This device significantly expands the data management and networking capabilities of the bedside glucometer. Networking technology should allow for a centralized quality control management.

The purpose of this research was to understand the current status of hospital information system(HIS) in Korea. Our main interests were when hospitals adopted each component of HIS and how they developed and managed the system. Structured questionnaires were applied to the department of each hospital in charge of managing information system. All hospitals, 276 in 1997, were included, and among them 93.5% responded. The HIS has been rapidly developed to include medical record management system, order communication system, laboratory information system, and picture archiving and communication system. The software for HIS was developed extramurally in more than half of all hospitals, and usually hardware was secured by buying than leasing them. Recently more hospitals has separated departments for His as independent units in hospital.

There is still lack of a convinient system that connect referring physicians to the information system of referral hospitals, We proposed to develop the laboratory-information-accessing system(LISA) for physicians referred to AMC referral center with Web-based internet technology. We constructed the menu of AMC Referral Center as a part of Asan Medical Center(AMC) homepage. The information of the referred patients wee collected in the separate internal server and then transferred to the external network sever by a batch. Referring physicians was able to connect to AMC Referral Center via AMC homepage and then browse the list of their patients by putting their identification number and password. At the next, the physicians chose the patients and the test item to be displayed. In order that the referral system is established tin the medical part, the LISA world be more needed, in the society, which internet is getting popular. This LISA was introduced successfully now, and it could be a model of national standard for hospital information system.

BACKGROUND: Test results in a laboratory are simply relayed to the laboratory information system through the interface. Middleware facilitates and manages the interaction between applications across heterogeneous computing platforms. We applied middleware to automated hematology analyzers in a clinical laboratory. METHODS: We used HemLink (Beckman Coulter Korea, Korea) as middleware between the laboratory information system and hematology analyzers. It provides quality control programs including the Westgard multirule chart and moving averages. RESULTS: Unlike the previous system, middleware does not require manual input of the quality control results. Amendment of quality control, if necessary, could be done without the help of hospital information teams. Identification of abnormal results with patient information could be achieved with moving averages. Morphology flags and system flags are checked at remote computers. CONCLUSIONS: Management of quality control results of hematology analyzers was easy via middleware. Thus, middleware could be useful to connect proficiency testing programs with HemLink and to compare results from laboratories using the same middleware.
