The Iowa Medical Information Network: a concept.

Iowa Methodist Medical Center (IMMC) was one of the nation's early developers of a "hospital/physician" system, entering the arena during October 1985, under the direction of Ginny Wagner. Their "MOLI-Link" system now serves over 150 physicians in 50 locations, and is currently undergoing significant enhancement. MOLI-Link was originally developed using Annson Systems (IBAX) products, and has recently migrated to Wallace Computer Services (Wal-Link) software. Over the past 4 years, IMMC has investigated wide-area medical information networking, and is now actively investigating development of the Iowa Medical Information Network. It is envisioned that IMIN would provide clinical, administrative, and educational information services throughout the IMMC 37 county referral area.

Brigham and Women's Hospital plans large MUMPS-based PC network.

Though many people say it simply cannot be done, Brigham and Women's Hospital is successfully implementing a network of 4,000 MUMPS-based PCs. The system takes advantage of standard hardware and software, and requires no customization. Today, the network serves as a prototype of similar installations nationwide.

Client-server MUMPS takes on the future.

The early stages of MUMPS demonstrated the language's reliability and functionality, yet it was limited to operating on standalone mainframe and minicomputer architectures. Slowly, as technology progressed and client-server networks became a reality, the speed and performance of MUMPS has brought new dimensions to healthcare.

Hospital reaps benefits from PC-based LIS.

The activity that takes place in a hospital's laboratory can greatly impact the real and perceived quality of patient care. And, as one Ohio hospital found, a networked laboratory system can make the benefits that much greater.

ImNet: a fibre optic LAN for digital image communication.

Data communication requirements in computer networks for medical diagnostics cannot be satisfied by existing LANs if digital images are involved because of the volumes of image data and the heterogeneity of data communication tasks. A user-oriented network behaviour requires a data transport rate which is beyond the physical bit rate of currently used LAN data channels. The key to an increased data transport efficiency is the separation of management data communication and image data communication. For the latter ImNet, a novel type of fibre optic network has been developed. Its hyperstar topology, its asynchronous data transport mechanism and its distributed network control make it particularly suited for PACS applications.

EMBL-search: a CD-ROM based database query system.

This paper describes a system of generally applicable index files provided on the EMBL sequence databases CD-ROM to facilitate the development of front-end software to the sequence databases available on this CD-ROM. The index files are used by a new versatile and user-friendly database retrieval program for the Apple Macintosh, EMBL-Search, which allows the easy construction of complex database queries. EMBL-Search utilizes cross-reference information contained in the databases to support navigation between different information resources. The ability to run EMBL-Search on a local computer network accessing a shared database CD-ROM makes its use particularly cost effective.

Heterogeneous computer network for real-time hemodynamic signal processing.

A computer network is described that allows real-time processing, graphical monitoring and off-line analysis of blood pressure, nervous activity and Doppler signals recorded in conscious rats. Real-time processing is performed by an acquisition station using a powerful microprocessor, allowing extraction and storage of several characteristic parameters from each cardiac cycle and real-time graphical monitoring. The experimenter can thereby follow the time evolution of the hemodynamic parameters. Experimental data are sent through the local network to a workstation that ensures off-line processing such as chronograms, histograms and statistical analyses.

A user-oriented protocol for integrating heterogeneous communication systems of medical facilities using ports.

The crucial feature of future communication systems in hospitals will be the heterogeneity between the individual systems. People working in a hospital do not communicate via data objects, but via highly complex functions like preparation of a patient report or diagnosis of patients' symptoms and signs. Essentially such tasks are accomplished by initiating remote functions in various modes of a communication system. The aim of the MEDAS protocol developed by our group is to propose a definition of such a high-level medical protocol and then to implement it. Our user-oriented protocol permits information exchange between heterogeneous systems. Modules and functions are defined. Message passing to and from a processor is realized using ports. The protocol sequence of every communication request is described. The relation of ports to the ISO model is specified. First experiences in a network for a medical school are reported.

[Informatics in a surgery department].

In this paper the Authors describe their own experience in applying informatics at the Surgical Division III of Azienda Policlinico Universitario of Messina. After a discussion about existing hardware (LAN of PC) and daily used software (commercial suite) for managing the clinical reports and correlated data (images, medical prescription, reservations, and so on), their conclusion is that a great development on this way will be possible with extension of the services to all the business network and then to WAN as Internet.

Wireless networking for the dental office: current wireless standards and security protocols.

Digital radiography has gained immense popularity in dentistry today in spite of the early difficulty for the profession to embrace the technology. The transition from film to digital has been happening at a faster pace in the fields of Orthodontics, Oral Surgery, Endodontics, Periodontics, and other specialties where the radiographic images (periapical, bitewing, panoramic, cephalometric, and skull radiographs) are being acquired digitally, stored within a server locally, and eventually accessed for diagnostic purposes, along with the rest of the patient data via the patient management software (PMS). A review of the literature shows the diagnostic performance of digital radiography is at least comparable to or even better than that of conventional radiography. Similarly, other digital diagnostic tools like caries detectors, cephalometric analysis software, and digital scanners were used for many years for the diagnosis and treatment planning purposes. The introduction of wireless charged-coupled device (CCD) sensors in early 2004 (Schick Technologies, Long Island City, NY) has moved digital radiography a step further into the wireless era. As with any emerging technology, there are concerns that should be looked into before adapting to the wireless environment. Foremost is the network security involved in the installation and usage of these wireless networks. This article deals with the existing standards and choices in wireless technologies that are available for implementation within a contemporary dental office. The network security protocols that protect the patient data and boost the efficiency of modern day dental clinics are enumerated.

Medical information networking and standardization.

There are few environments that generate and manage as much information as the hospital. Although computers are used extensively to manage this information, their application has been opportunistic rather than strategic. This has led to a multi-vendor information processing environment in many hospitals. Hospitals today have financial systems, order-entry communication systems, ADT systems, and clinical systems such as laboratory, pharmacy, etc. Communication between these islands of automation however are still, for the most part, primitive. Exceptions are in the large teaching hospitals where internal staff have been utilized to link systems together. The effort has traditionally been huge and fraught with difficulties related to the heterogeneous environment that is involved. In order to overcome these problems and enable us to truly bring the power of modern computing to bear on hospital-wide problems, as well as to make feasible, for example, the computerized medical record, we must develop an appropriate strategy. It seems unlikely that a single-vendor solution will entirely answer hospital information processing needs. Therefore, a perpetuation of the heterogeneous environment is inevitable. With this in mind, an alternative approach is proposed: to develop networking standards for the hospital, as has been done for the manufacturing and technical office environment, such that vendors can build systems that can be easily integrated.
