ABSTRACT
In the pathophysiology experiment teaching,by combining the teaching of prob-lem-based learning with local area network(LAN) teaching,students first carry out a simple ex-periment to ask a question on the observed phenomenon,and then put forward a hypothesis,de-sign experiments to answer questions,and implement the experiment,and finally present experi-mental results.Such experimental design teaching is not only a great way to mobilize the stu-dents’interest in scientific research and learning initiative,but also greatly enhances the effi-ciency of the experiment.Students preliminarily master the basic scientific research program and methods.
ABSTRACT
OBJECTIVE: To monitor clinical rational use of drugs,analyze the problems involved and to put forward reasonable suggestions.METHODS: Using the platform of medical information communication established based on the "Military Medical Project No.1" local area network and "Hospital Information Management System",the electronic medical records of the inpatients,ward round records,treatment plans and the relative laboratory test reports from October 2006 to March 2007 were retrieved online.The involved problems were discussed with clinical physicians through the network.RESULTS: The problems in the clinical drug use manifested as repeated medication,improper administration,overdoses and adverse interactions of combined drugs.The irrational prophylactic administration of antibiotics in the surgical department was characterized by improper choice of drugs and prolonged course of treatment etc.CONCLUSION: Great importance should be attached to drug interactions,and the indications for drug combination and course of treatment should be kept under tightly control so as to reduce adverse reactions and delay the onset of drug resistance.
ABSTRACT
BACKGROUND: Point-of-care (POC) testing is expanding because of the many advantages, such as faster turnaround time, immediate decision making and patient management. However, POC testing has problems; poor maintenance and quality control of devices and management of test results. We installed data management system (DMS) for POC blood gas analyzers using local area network for the resolution of those problems. METHODS: We connected nine POC blood gas analyzers Rapidpoint 400 (Bayer Diagnostics Ltd., Newbury, UK) to POC data manager Rapidlink (Bayer Diagnostics Ltd.) by device interface using local area network and developed in-house program for connecting POC data manager to laboratory information system (LIS)/hospital information system (HIS). We surveyed user acceptability and reliability of test results. We examined patterns of problems detected and solved in operating DMS based on quality records. We calculated the change of the yearly test numbers of arterial blood gas analysis (ABGA) after installation of DMS. RESULTS: Test results of POC blood gas analyzers were transferred to LIS and could be checked in HIS. By means of user survey, we judged that the users of POC blood gas analyzers operated the devices with ease and thought test results reliable. POC data manager server implemented in central laboratory enabled remote maintenance and quality control of devices with little workload. POC ABGA test number increased by 3.7 fold during the two years. CONCLUSIONS: We developed DMS for POC blood gas analyzers, enabling test result retrieval and remote maintenance and quality control of devices. This is very informative study for other hospitals installing DMS for POC testing in Korea.

Objective To achieve the software automatic updates and maintenance in the local area network which is developed based on the C/S structure. Methods Based on the existing software and hardware development platform,we use PowerBuilder to exploit and compile a program which can determine whether the software need to update automatically or not under the premise of unchanging the existing LAN software system. Results When the user terminal in the local area network runs this program,they can update it automatically whenever they need. Conclusion This method will greatly reduce the later maintenance software,upgrade works and also improve the work efficiency and accuracy.

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 labelling. The data were analyzed by Student's T-test and SAS (version 6.04, U.S.A.). 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 turnaround time in blood 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.
