A secure Web-based interface to maternity records with decision support.

The recent developments in Web technology now make it easy to create user-friendly interfaces to databases and link them to the Internet or to local Intranets. With the acceptance of this new approach one can take advantage of the opportunity to use this development to incorporate additional knowledge into the interface. Not only can this provide a more supportive interface, but it can also create the opportunity for sharing and comparing such knowledge in the future. This paper describes how this has been used to develop an interface to a database of maternity case records which incorporates a knowledge base of rules relating to care plan protocols and uses this to provide decision support to the carer. The issue of security is a serious problem and some aspects of the measures taken are discussed.

Pain clinic EPR: requirements determination & configuration.

UNLABELLED: The focus of this study was to determine requirements for a general pain EPR (electronic patient record), design this EPR and develop a prototype for demo purposes in pain clinics in The Netherlands. The specifications for this EPR were derived from the 'Nijmegen Classification of Pain', analysis of patient paper records and in-depth interviews with six anaesthesiologists, three physiotherapists and two psychologists. For development a generic configuration tool was used. The actual EPR consisted of five components (two for the anaesthesiologists, one for the physiotherapist, one for the psychologist and one for the whole team). The five components comprised of numerous dialogues. The medical care process directed these dialogues. CONCLUSIONS: The different organisational settings and the variability in provided patient care compromised the development of an EPR for all pain clinics. Defining the granularity of the dialogues was influenced mainly by the factors mentioned previously. However, most respondents agreed on the importance of the following functional demands: registration speed, security, flexibility and supporting of communication between the care providers.

A methodology for evaluation of knowledge-based systems in medicine.

Evaluation is critical to the development and successful integration of knowledge-based systems into their application environment. This is of particular importance in the medical domain--not only for reasons of safety and correctness, but also to reinforce the users' confidence in these systems. In this paper we describe an iterative, four-phased development evaluation cycle covering the following areas: (i) early prototype development, (ii) validity of the system, (iii) functionality of the system, and (iv) impact of the system.

Wireless and Web-based medical monitoring in the home.

A remote medical monitoring system is described, which continuously monitors patients' state of health. The system uses the services provided by intranets and the Internet to allow remote supervision of patients, who may be domiciled in their own home. A hardware/software prototype system has been constructed to demonstrate the use of non-invasive and minimally intrusive sensors attached to patients. Continuous real-time data is acquired, stored and processed. A wireless system or wires connect these monitor devices to the World Wide Web and, on request, information is delivered to authorized medical staff via a web browser or Wireless Application Protocol-enabled mobile telephones. Medical staff may examine real-time data or graphical information and make comparisons with historical data. Parameters may be set to select and control the data acquisition devices. The potential exists for augmentation of patient health by development of novel sensors and low-power electronic circuitry, and this research continues.

Intranet technology in hospital information systems.

The clinical information system architecture at the Columbia-Presbyterian Medical Center in New York is being incorporated into an intranet using Internet and World Wide Web protocols. The result is an Enterprise-Wide Web which provides more flexibility for access to specific patient information and general medical knowledge. Critical aspects of the architecture include a central data repository and a vocabulary server. The new architecture provides ways of displaying patient information in summary, graphical, and multimedia forms. Using customized links called Infobuttons, we provide access to on-line information resources available on the World Wide Web. Our experience to date has raised a number of interesting issues about the use of this technology for health care systems.

An approach for access differentiation design in medical distributed applications built on databases.

A formalized "top to bottom" design approach was described in [1] for distributed applications built on databases, which were considered as a medium between virtual and real user environments for a specific medical application. Merging different components within a unified distributed application posits new essential problems for software. Particularly protection tools, which are sufficient separately, become deficient during the integration due to specific additional links and relationships not considered formerly. E.g., it is impossible to protect a shared object in the virtual operating room using only DBMS protection tools, if the object is stored as a record in DB tables. The solution of the problem should be found only within the more general application framework. Appropriate tools are absent or unavailable. The present paper suggests a detailed outline of a design and testing toolset for access differentiation systems (ADS) in distributed medical applications which use databases. The appropriate formal model as well as tools for its mapping to a DMBS are suggested. Remote users connected via global networks are considered too.

Integrating legacy laboratory information systems into a client-server world: the University of Minnesota Clinical Workstation (CWS) project.

The development of an innovative clinical decision-support project such as the University of Minnesota's Clinical Workstation initiative mandates the use of modern client-server network architectures. Preexisting conventional laboratory information systems (LIS) cannot be quickly replaced with client-server equivalents because of the cost and relative unavailability of such systems. Thus, embedding strategies that effectively integrate legacy information systems are needed. Our strategy led to the adoption of a multi-layered connection architecture that provides a data feed from our existing LIS to a new network-based relational database management system. By careful design, we maximize the use of open standards in our layered connection structure to provide data, requisition, or event messaging in several formats. Each layer is optimized to provide needed services to existing hospital clients and is well positioned to support future hospital network clients.

Experiences with a distributed virtual patient record system.

TeleMed is a distributed diagnosis and analysis system, which permits physicians who are not collocated to consult on the status of a patient. The patient's record is dynamically constructed from data that may reside at several sites but which can be quickly assembled for viewing by pointing to the patient's name. Then, a graphical patient record appears, through which consulting physicians can retrieve textual and radiographic data with a single mouse click. TeleMed uses modern distributed object technology and emerging telecollaboration tools.

Medicine and the Internet.

Practicing physicians are frequently overwhelmed by the amount of new medical information. The internet is increasingly becoming an important vehicle for accessing that information with a variety of online resources for medical professionals. In its current state, however, the internet abounds with misleading information, making it difficult to sort out what is both meaningful and accurate from among the thousands of electronic documents. In this article, we list medical web sites that we have found to be useful, accurate, and easy to navigate. We also give an overview of the internet and World Wide Web to provide a starting point for novice users, and we briefly discuss how internet policy relates to medical practice.

Secure three-dimensional data transmission and display.

An optical three-dimensional (3D) display system interfaced with digital data transmission is proposed. In this system, an original 3D object is encrypted by use of a random phase mask and then the encrypted pattern is recorded as a digital hologram. The digital hologram key is also recorded for optical decryption. Both the encrypted digital hologram and the digital hologram key are transmitted to a receiver through a conventional communication data channel. At the receiver, the 3D scene is reconstructed and displayed optically in a retrieval system based on a joint-transform correlation. Experimental results are presented. We investigate the influence of quantization of the joint power spectrum in the optical correlator on the quality of the reconstructed image.

Attention for security now more needed than ever.

Security is a major consideration for any computer system. Today the topic security is defined and divided in three different domains: confidentiality, integrity and availability. This paper deals with the topic availability and the fact that hospitals are getting more and more dependent of their computer systems In this contribution the different aspects of availability and non-availability are described and measures are mentioned to lower the risk of dysfunction in the hospital in case the system completely has collapsed for a longer period.

Simultaneous storage of patient information with medical images in the frequency domain.

Digital watermarking is a technique of hiding specific identification data for copyright authentication. Most of the medical images are compressed by joint photographic experts group (JPEG) standard for storage. The watermarking is adapted here for interleaving patient information with medical images during JPEG compression, to reduce storage and transmission overheads. The text data is encrypted before interleaving with images in the frequency domain to ensure greater security. The graphical signals are also interleaved with the image. The result of this work is tabulated for a specific example and also compared with the spatial domain interleaving.

Small PACS for digital medical images--reliability and security in a clinical setting.

Recently we introduced a small Picture Archiving Communication System (PACS) for handling CT and MRI data. Our experience with this system has been useful in identifying potential problems in a clinical setting. Since the use of PACS raises both medical and social concerns, it cannot be instituted without addressing concerns related to the reliability and security issues. Although PACS is useful in the management of medical images, there are concerns about their reliability and security in a clinical setting. Reliability encompassed image quality, timeliness of the reports, and the PACS to the Radiological Information System (RIS) interface including the retrieval of the previously obtained images. The security of the patient's medical data is also essential.
