EMG-LAB computer system for routine electromyography.

The new computer aided program for fully automatic single MUAPs and IP analysis is described. This software programs called EMG-LAB represents the integrated system of IBM PC/AT computer with any kind of EMG machine. The individual MUAPs are automatically extracted, identified and measured on line, thanks to the sophisticated program based on statistical averaging. All the measured parameters like duration, amplitudes, areas, turns and phases are presented in computer display in a form of histograms. The summary of complete examination are presented in six parameters in form of histograms together with statistical values representing their distribution and variability. Those histograms represent the MUAPs waveforms remodeled during different disease processes. During maximum voluntary effort the interference pattern analysis is made on the new developed method. It allows to determine the parameters of different MU size, their quantity and intensity of recruitment. The most specific feature of this analysis concerns the information of the background activity, where the indirect data of single MUAPs and their parameters typical for given pathology could also be evaluated from interference pattern.

A strategy for empowerment: the role of midwives in computer systems implementation.

The procurement and implementation of patient administration systems has been done on numerous occasions in the past. The Rotunda project however encompassed major bespoke clinical developments which were going to impact upon large clusters of midwives, and medical staff to a lesser extent. A broad based four level structured methodology was used to implement the project which is significantly ahead of schedule. This methodology together with its strengths and weaknesses is comprehensively discussed. The empowerment of midwives, their roles in systems analysis and design, software testing and organisational re-engineering is described. The importance of undertaking comprehensive computer training is highlighted and a compact 10 h information technology course coupled with ongoing educational and related activities which could be adopted by any organisation is documented. The seven deadly sins of project management are mapped out. An update on benefits realisation is provided. Gender issues are also discussed.

Computational systems analysis of developmental toxicity: design, development and implementation of a Birth Defects Systems Manager (BDSM).

Birth defects and developmental disabilities remain an important public health issue worldwide. With the availability of genomic sequences from a growing number of human and model organisms and the rapid expansion of the public repositories holding large-scale gene expression datasets, a computational systems analysis of developmental toxicology can incorporate this vast digital information toward the realization of predictive models for complex disease. Here we describe the initial design, development and implementation of a Birth Defects Systems Manager (BDSM). The project was motivated by the need for a computational-bioinformatics infrastructure to manage vast digital information from functional genomics and for a new knowledge environment specifically engineered for the analysis of developmental processes and toxicities. Proof-of-concept tested BDSM using meta-analysis of gene expression data collected from different laboratories, technology platforms, and study models. The composite dataset incorporated 232 microarray comparisons of RNA samples by single or dual microarray platforms, cDNA or oligonucleotide based probes, and human or mouse sequence information. Preliminary results identified system-level features in the embryonic transcriptome as it reacted to various developmental-teratological stimuli. BDSM is open access through the worldwide web (http://systemsanalysis.louisville.edu/) and can be integrated with other bioinformatics tools and resources to advance the pace of discovery in birth defects research.

Development of a wearable computer system with a hands-free operation interface for the use of home health caregiver.

We previously developed a network-based medical care support system called the Hyper Hospital, a computer network with an interface that is dedicated to patient care. In this study, we developed a wearable information system that is designed so that a caregiver can obtain information and control various support devices within the home-care environment. In our system, the wearable computer itself consists of a computer network built into a jacket. Each required function is implemented by a dedicated small computer connected to the in-jacket network. A new function may easily be added to the system by connecting additional computers. A network comprising such a set of single-function computers becomes a highly efficient information system when applied to health care support.

Capability of hospital computer systems in performing drug-use evaluations and adverse drug event monitoring.

A survey to determine the extent of computerization in key areas of hospitals, the information being collected in the databases, and the capabilities of the computer systems for performing adverse drug event monitoring and drug-use evaluations was conducted. The questionnaire was distributed to clinical pharmacists in the 500 hospitals composing the Drug Surveillance Network. In the majority of the 166 responding hospitals (> 85%), the pharmacy department, clinical chemistry and hematology laboratories, patient admissions, and microbiology laboratory were computerized for data acquisition and management. The medical records and purchasing departments were computerized in a smaller proportion of hospitals (75% and 74%, respectively). In the majority of hospitals with a computerized pharmacy department (> 78%), there was ready access to computer databases in other departments, but simultaneous querying of multiple databases was possible in only 30%. Patients could be identified according to diagnosis in 82% of the hospitals and according to medication received in 83%. More than 85% of responding hospitals had implemented spontaneous reporting systems for the identification of adverse drug events. Computers are widely used in hospitals participating in the Drug Surveillance Network, but a substantial effort is necessary to make these resources more useful and to standardize processes so that data may be pooled across institutions to deal with important public health concerns.

How to design a radiation safety computer system.

If an institution needed a radiation safety database, where would they begin? Would they buy or design a database? If they purchase a database, should it be a commercial off-the-shelf system? Or should they use a hosted database accessed from the Internet? What should the database do? What should be its purpose? Many aspects of system design are the same at any institution. Therefore, the design, development, and deployment of a radiation safety computer system is discussed that primarily is useful for a large biomedical research institution but could be adapted to smaller facilities. The discussion also includes the use of a hosted database system but not developed systems that could be purchased.

[Developing a home care nursing information system by utilizing wire-wireless network and mobile computing system].

PURPOSE: The purpose of this study was to develop a home care nursing network system for operating home care effectively and efficiently by utilizing a wire-wireless network and mobile computing in order to record and send patients' data in real time, and by combining the headquarter office and the local offices with home care nurses over the Internet. It complements the preceding research from 1999 by adding home care nursing standard guidelines and upgrading the PDA program. METHOD: Method/1 and Prototyping were adopted to develop the main network system. RESULT: The detailed research process is as follows : 1)home care nursing standard guidelines for Diabetes, cancer and peritoneal-dialysis were added in 12 domains of nursing problem fields with nursing assessment/intervention algorithms. 2) complementing the PDA program was done by omitting and integrating the home care nursing algorithm path which is unnecessary and duplicated. Also, upgrading the PDA system was done by utilizing the machinery and tools where the PDA and the data transmission modem are integrated, CDMX-1X base construction, in order to reduce a transmission error or transmission failure.

Transferability of a computer system for medical history taking and decision support in dyspepsia. A comparison of indicants for peptic ulcer disease.

The transferability of a British data base for differential diagnosis of dyspepsia using data obtained by computer interrogation was tested in 467 Swedish patients. The diagnostic value for peptic ulcer disease of symptoms such as frequent night pain relieved by food or antacids, smoking, family history of ulcer, food relief pain, male sex, and episodic pain was shown to be reproducible. However, for a number of symptoms their value for the diagnosis of peptic ulcer disease could not be reproduced in Swedish patients. The combined value of indicants was tested using a computer based algorithm for calculating diagnostic probabilities. The performance of this algorithm was poor when British data were applied to Swedish patients but reclassification of the Swedish patients on their own data base showed promising results. Crean and colleagues in Glasgow have developed a computer system for automated interrogation of patients with dyspepsia. The system utilises a large number of questions to obtain information regarding a maximum of 160 diagnostic indicants. The symptoms elicited from a patient can be compared with those of a large number of previously examined patients and the probabilities of ten different diagnoses can be calculated. The calculation of diagnostic probabilities is based on scores reflecting the diagnostic value of different symptoms in different diseases. After careful translation of questions the system has been transferred for use in Sweden. The present report is based on data from patients seen during the first two years with the system at a Swedish hospital.(ABSTRACT TRUNCATED AT 250 WORDS)
