Electromagnetic Interference of Wireless Local Area Network on Electrocardiogram Monitoring System: A Case Report

Electromagnetic interference (EMI) can affect various medical devices. Herein, we report the case of EMI from wireless local area network (WLAN) on an electrocardiogram (ECG) monitoring system. A patient who had a prior myocardial infarction participated in the cardiac rehabilitation program in the sports medicine center of our hospital under the wireless ECG monitoring system. After WLAN was installed, wireless ECG monitoring system failed to show a proper ECG signal. ECG signal was distorted when WLAN was turned on, but it was normalized after turning off the WLAN.

Installation of Network-Connected Point-of-Care Blood Glucose Meters / 임상검사와정도관리

Point-of-care (POC) testing is desirable because of both the ease with which it can be administered and its short turnaround time. However, because standard POC devices cannot transmit test results automatically to a laboratory information system (LIS), each result must be recorded by hand. This inconvenience not only increases the possibility of clerical errors, but also limits the proper use of test results. If POC test results are not saved in the LIS, it is hard to either monitor patients' health trends or to quality control (QC) the test results. In this paper, we describe how we have solved these problems by connecting 250 POC blood glucose test devices to the LIS via a local area network (LAN). After connecting the POC devices (we used the Accu-Chek Inform II; Roche Diagnostics, Germany) to a manufacturer-provided POC data management system (Roche's Cobas IT 1000; Roche Diagnostics), we developed our own interface program for delivering data from the Cobas IT 1000 system to the LIS. By installing a program to scan the identification barcode worn by patients on their wrists, network-connected POC devices enable users to omit extra ordering, receiving, and recording processes, and they also reduce the possibility of patient misidentification. Such a system also provides an effective way for physicians to follow both the current and accumulated test results of patients. We note that performing QC on glucometers and the sending of data via LAN to the LIS are necessary steps to monitor both patients' results and the QC of those results.

Recent Change of locality as Risk Factor for Malaria Fever among New Residents of Ahoada East Local Government Area in Southern Nigeria

Relocation which is a well-known determinant of malaria in non-immune travelers to malarious areas; has also been found to be a risk factor for malaria among semi-immune persons who change locality within endemic regions. Further research evidence suggests that the higher transmission intensity at the travel location is an underlying factor which may indicate exposure to new variants of P falciparum for which specific immunity is lacking. This study was conducted to determine if recent change of locality increased the risk of malaria fever among semi-immune National Youth Service Corps members serving in a district in southern Nigeria.Method: Ninety six corps members who had just been posted to Ahoada-East LGA in southern Nigeria and 83 others that had been in service for six months; were followed up for malaria fever in a prospective cohort design over a 3 month period from September 2010 to December 2010. Active surveillance was used to obtain reports of fever among the cohort; followed by medical examination at designated local health facilities.Results: No significant differences in age and use of protection against malaria were found between the study groups. The incidence proportion of malaria for the recently relocated group (34) was significantly higher than that of the resident group (15.7). Recent change of locality was more associated with malaria fever (RR 2.19; 95 CI 1.243.88; AR 54.4).Conclusion: The recent change of locality within an endemic region; which serves as an indicator of exposure to new variants of P falciparum; for which specific immunity is lacking; is a significant risk factor for malaria fever. Protection against malaria is recommended for semi-immune individuals moving to new locations with significant risk of malaria transmission

Hospital Wireless Local Area Network-Based Tracking System / 대한의료정보학회지

OBJECTIVES: The purpose of this study was to develop a prototype wireless local area network (LAN)-based tracking system and evaluate its efficacy. METHODS: A wireless LAN-based tracking system was developed with a personal digital assistant (PDA) having a simple text messaging function and a prototype stand-alone tracking device. Evaluation of the effectiveness of the tracking system was performed in two ways. Twenty-five messages were sent to nurses by direct communication and 46 messages were sent by the wireless system. Thirty cases by nurses and 30 cases by the wireless system to locate hospital equipment were performed. The time required to transfer messages and to locate equipment was measured and analyzed with a Mann-Whitney test and a paired t-test, respectively. RESULTS: The mean time required to transfer messages by direct communication and by the wireless system were 37.92 +/- 19.19 seconds and 30.65 +/- 9.80 seconds, respectively which were not statistically different (p = 0.108). The mean time required to locate equipment by the nurses and by the wireless system was 234.00 +/- 59.99 and 23.97 +/- 6.17 seconds, respectively which was statistically different (p < 0.001). CONCLUSIONS: The wireless LAN-based tracking system can save time for nurses to communicate and to check for the location of equipment in wards which allows nurses to spend more time and attention to patient care and safety.

Nosocomial Infection Management Using Web Site established in the LAN / 日本農村医学会雑誌

Nosocomial infection management is one of the most important subjects in terms of risk management in a hospital. To achieve the nosocomial infection management appropriately, both public relations and information gathering are important. When it comes to publicity, it is desirable that information is offered quickly and efficiently and the personnel are able to access the information easily anytime and wherever they are. As for information gathering, it is also important to collect the information concerning the nosocomial infection promptly, and to tell it quickly to infection management persons including infection control team members. The infection control committee of our hospital has engaged in both publicity and information gathering by using the committee web site established in the LAN of the hospital since January 2004. The web site carries notifications, organization chart, list of committee members, various manuals, guidance of educational activities, infection management, etc. It is also used for questions and answers, and gathering information concerning nosocomial infection. The number of times the web site was accessed was about 200 every month, and was considerable at night and on holidays. This method of using the web site seems to be useful to promote nosocomial infection management.

Experiencia del registro electrónico de pacientes en un Servicio Universitario de Neonatología / Experience with electronic files in a University Neonatology Unit

The electronic file is a reality in medical practice nowadays. We have a decade of experience with electronic files in a neonatology unit. We use a local network that consists in one server and 8 connected computers, distributed in the hospital. Filemaker Pro® is used as database administrator and access to data is protected with passwords. Data entry is made by health care professionals in charge of the patients. Patient's reports and statistical information are based on data entered to the system. This methodology allows to have update clinical data, indexing of information, to maintain track of pharmacological indications, prescribe parenteral nutrition and obtain information for research purpose. It is possible therefore, with a minimal computing expertise, to devise electronic files that can improve the quality of health care.

Installation of Data Management System for Point-of-care Blood Gas Analyzers using Local Area Network / 대한진단검사의학회지

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.
