A proposal of an off-line PACS based on a personal database.

Problems with picture archiving and communication systems (PACS) are focused and an off-line PACS of practical value is proposed in this paper. This system is based on the personal database where each patient has his/her own recording medium. This medium files all medical information as well as images of value, and is carried with a patient through hospital. Advantages over the conventional or on-line PACS communicating through a network are discussed and a possibility of practical use is analysed showing a prototype system. The biggest advantage of this system is quick and easy access to the images of concern and a small amount of cost for initial investment. It is also pointed out that the format of the data recording on the disk has to be standardized so that this system could be used for a medical care system over a wide area.

Health and welfare data on optical memory cards in Isehara city.

An off-line network system of health and welfare for elderly people using optical memory cards has been established in Isehara city (Japan) since 1991. 2775 citizens have the cards and 24 offices have the terminals. It covers almost one third of people aged over 65 in Isehara city and almost all of the offices concerned with their health and welfare. About a half of holders use optical memory cards every time they visit these offices. The optical memory card holds data including basic data for health and welfare, health check data over 5 years, medical images with scripts and history of welfare services. All the data are used for medical care, health consultation and management of health and welfare services. A card can hold health and welfare data for a lifetime, and it is easy to expand the system. It has been a good experience for us, because the optical memory card system needs co-operation among citizens, medical association and local government, and the experience will help us to expand the system in the future.

An introduction to fractal imaging technology.

In this article the author explains the basic theory and practical applications of the latest advancement in imaging technology called fractal imaging. Fractal imaging is a unique way of compressing and storing images which has unlocked the door to the restrictions imposed by conventional imaging technology as regards storage and transmission of high quality images. The article outlines how this technology has been successfully applied by the creation of the first and only fractal photographic archival and retrieval system in Scotland, in the form of the George Washington Wilson collection comprising 44,000 images and associated text in only 450 megabytes (Mb) of disc space.

An application of an optical disk filing system to the management of medical records.

An optical disk filing system is a promising new method to memorize the contents of medical records. However, due to problems of image quality, input speed and durability with the disk, this has not yet been put to practical use. In the present study the image quality of the laser disk system installed in our hospital were checked, and this system was thought to be useful to store discharge summary. We developed discharge summary management system by inputting into the optical disks the discharge summary written freely by doctors and the discharge abstract automatically formed by computer.

Computers are stepping stones to improved imaging.

Never before has the radiology industry embraced the computer with such enthusiasm. Graphics supercomputers as well as UNIX- and RISC-based computing platforms are turning up in every digital imaging modality and especially in systems designed to enhance and transmit images, says author Greg Freiherr on assignment for Computers in Healthcare at the Radiological Society of North America conference in Chicago.

Optical disk testing opens hospital's eyes.

After six months of testing, Beth Israel Medical Center in New York City is ready to say "yes" to optical disk storage of medical records. Eventually, the system is expected to help eliminate storage costs for 4 million pieces of paper per year, microfilming costs of $200,000 per year and labor costs for pulling and refiling 700 charts every day.

Integrated information and image management systems for the 90s.

The rising number of implementations of PACS (Picture Archiving and Communications Systems) subsystems, specialized information systems (radiology, laboratory, pharmacy, and other ancillary departments), and increased interest in the role of optical storage systems hospitalwide, creates an environment that demands the integration of each of these systems if the hospital is to operate at maximum profitability levels. This has been recognized by several groups who have proposed standards for communication between vendors and systems, and their efforts, combined with the support of the hospitals, will hopefully allow the promise of a fully electronic hospital to become a reality. While the concept of a totally integrated fully electronic hospital has been with us for over a decade, only recently have medical vendors attempted to evolve from a conceptual phase to one of workable, cost-effective systems. Few will debate the fact that the fully integrated information and image management system is still several years away, yet many hospitals have recognized the importance of planning for use of the component technology available today. This planning stage is critical and, combined with the phased implementation of the existing technologies, it can provide significant advantages in the overall acceptance of this future technology. This paper addresses the role of the standards organizations in making this integration a reality, how conceptually a fully integrated information and image management system will work, new technologies and their potential uses in the hospital, and both the advantages the technology can bring in solving existing problems and hurdles that still need to be overcome.

Image-based document management systems for medical records.

Using image scanning as a document capture mechanism at time of treatment or on day of discharge automates the medical record to achieve the larger objectives of simultaneous concurrent access to an electronic chart. This form of keyless document capture, although appearing labor intensive, is justified for improving business management and quality of care. Coupled with optical character recognition or barcode recognition for keyless data capture, medical information may be more easily made available for clinical research. Not merely a microfilm alternative, a medical record management system accelerates chart completion. Labor reduction is realized by eliminating filing and retrieval of active charts, loose sheet handling, photocopying, chart assembly, and chart location control. By reducing the reasons for chart completion delays, accelerated billing of Medicare accounts will occur, resulting in a reduction in receivables. Image-based document management systems accomplish the three things required of a senior manager in health care: (1) solve problems, (2) save money, and (3) make money.

Patient cards: storage and input for medical data.

The literature concerning the diffusion of innovations reveals that it is not surprising that a promising technology is confronting obstacles in its development and implementation. Alternative technologies also often appear that address the same or similar problems. Better information enables physicians to provide medical care that is less expensive and less error prone. The prescription of medications is reduced in number and cost when the prescribing physician knows the current and previous medications of the patient. The ordering of clinical tests is reduced in number and cost, and the ordering of timely retesting is more likely when physicians have before them information about previous testing of their patient. The challenge is in how the portability of the patient card and its ability to be self-contained can enhance medical practice.

Overruled: objections to optical disk archiving.

In summary, while the Federal Rules of Evidence neglect to specifically address the admission of optical disk evidence, the Rules do recognize the reliability and admissibility of records maintained with modern computer storage techniques. In certain cases, information stored on optical disk will constitute original information; in others, the information will constitute an admissible duplicate. Regardless of the classification, the optical disk evidence should be admissible if the party offering the evidence can establish that the optical disk storage and retrieval process accurately reproduces the original document. The admission of medical records stored on optical disk will be challenged. The technology involved in optical disk storage, however, makes optical disk information more reliable than magnetic disk information. As a result, optical disk evidence currently should survive challenges more readily than magnetic disk evidence.
