Surveillance for the Expanded Programme on Immunization.

Surveillance is the foundation of public health practice. This review examines the experience of surveillance in the Expanded Programme on Immunization (EPI). Surveillance systems include routine reporting, sentinel surveillance, and community-based reporting. Data from ongoing surveillance should be linked with those from supervision, health facility assessments, population surveys, and outbreak investigations to provide information for programme planning, implementation, evaluation, and modification. Evaluation of surveillance systems should assess the extent to which data are used for policy-making and programme improvement, and the simplicity, accuracy, completeness, timeliness and cost of the data. The surveillance of vaccine-preventable diseases has evolved as programmes mature, to monitor progress towards disease control targets. The establishment of goals to reduce measles cases by 90%, eliminate neonatal tetanus, and eradicate poliomyelitis has put increased emphasis on the need for effective disease surveillance. This opportunity should be taken to promote strengthening of national routine systems for disease surveillance, to make them effective instruments for prevention and control of diseases of public health importance.

The strategic and operational characteristics of a distributed phased archive for a multivendor incremental implementation of picture archiving and communications systems.

The long-term (10 years) multimodality distributed phased archive for the Medical Information, Communication and Archive System (MICAS) is being implemented in three phases. The selection process took approximately 10 months. Based on the mandatory archive attributes and desirable features, Cemax-Icon (Fremont, CA) was selected as the vendor. The archive provides for an open-solution allowing incorporation of leading edge, "best of breed" hardware and software and provides maximum flexibility and automation of workflow both within and outside of radiology. The solution selected is media-independent, provides expandable storage capacity, and will provide redundancy and fault tolerance in phase II at minimum cost. Other attributes of the archive include scalable archive strategy, virtual image database with global query, and an object-oriented database. The archive is seamlessly integrated with the radiology information system (RIS) and provides automated fetching and routing, automated study reconciliation using modality worklist manager, clinical reports available at any Digital Imaging and Communications in Medicine (DICOM) workstation, and studies available for interpretation whether validated or not. Within 24 hours after a new study is acquired, four copies will reside within different components of the archive including a copy that can be stored off-site. Phase II of the archive will be installed during 1999 and will include a second Cemax-Icon archive and database using archive manager (AM) Version 4.0 in a second computer room.

The clinical display of radiologic information as an interactive multimedia report.

We regard the delivery of radiological information as an interactive multimedia report. We use a multimedia report model based on Extensible Markup Language (XML), rather than a traditional workstation model. Others have suggested a similar document-based approach. This display presentation includes image-related and text-based information and may contain interactive components (e.g., window, level and zoom). Using XML as a foundation for this multimedia presentation, we achieve flexibility and platform independence at a lower cost. XML allows for the separation of content and form. Content information, defined as elements (e.g., images, radiologic reports, and demographic information), is treated as independent information objects. The behavior of the elements can be changed for different users and tasks. In addition, by separating format detail from content, the appearance of the elements within the report can be modified. XML does not replace existing standards (i.e., Digital Imaging and Communications in Medicine [DICOM], Transmission Control Protocol/Internet Protocol [TCP/IP]). Instead, it provides a powerful framework that is used in combination with existing standards to allow system designers to modify display characteristics based on user need. We describe our application of XML to the clinical display of radiologic information.

A cost analysis of film image management and four PACS based on different network protocols.

Picture Archive and Communication Systems (PACS), which allow the electronic acquisition, storage, transportation, and viewing of medical images, hold the eventual promise of reduced costs, improved image-management logistics, and ultimately, improved patient care. But at what point in the future will PACS really cost less than film-based image management for a given hospital size; and how are these costs affected by the choice of the digital communication network? To address these questions, a static differential cost model has been constructed. PAC systems based on two high-speed networks (less than 150 megabytes per second Mbps) and two low-speed networks, as well as film, were considered for five different sized hospitals (ranging from 15,000 to 125,000 procedures per year) and two time periods (1995 and 2000). PACS equipment was assumed to have a payoff of five years. The model considered all capital and supply costs and personnel costs for the PACS and for film storage and retrieval. It did not consider any possible cost savings from logistics improvement likely to result from the adoption of a PACS. Based on the assumptions outlined, high-speed-network PACS are less costly than those based on low-speed networks for all scenarios considered. Further, even though all possible PACS cost savings were not considered, high-speed network PACS appear to be less costly than film for hospitals larger than 60,000 procedures in 1995 and larger than 15,000 in 2000, while low-speed-network PACS should cost less than film for 60,000 and 30,000 procedure hospitals in 1995 and 2000 respectively.

Benefits of coordinated action in PACS evaluation.

PACS, a health care technology still in its developmental stage, aims to improve the management of diagnostic imaging investigations. As the technology has not been comprehensively assessed, data and facts to justify its clinical, economic and other benefits are to date insufficient. Through internationally coordinated action, it is expected to obtain a faster and more comprehensive technology assessment of PACS as well as recommendations for optimization of the system and guidelines for its rational use in various health care environments.

Methods of automatically acquiring images from digital medical systems.

Automated image acquisition plays an important role in a picture archiving and communication system (PACS). However, there is no single solution for automated data acquisition from existing digital medical imaging systems. We have gained a great deal of experience on automatic acquiring data by interfacing imaging scanners of major manufacturers. In this paper, we categorize the interface methods supported by the current image scanners. This categorization consists of five architectural models: (a) sequential chain; (b) direct interface; (c) memory access; (d) shared disk; and (e) interconnected network. The cost, rate of data transfer, and ease of implementation of each model are discussed. To ensure the integrity and availability of patient images in a PACS system, automated fault tolerance design in image acquisition is required. Based upon our field data, we report common scenarios which cause the acquisition to fail. We also describe techniques employed to automatically restart the operations which include recovery from acquisition processes' errors and traps, image acquisition computer down-time occurrence, and shutdown occurrence of medical imaging system.

A low-cost PCI-bus-based ultrasound system for use in image-guided neurosurgery.

A low-cost PCI-bus-based ultrasound sub-system has been developed and integrated into the image-guided neurosurgery system currently in use at the Cleveland Clinic. Two software applications have been developed that integrate real-time ultrasound images with preoperative MR and CT data sets. By tracking the position of the ultrasound probe during surgery, it is possible to display a real time ultrasound image and the corresponding (preoperative) oblique CT or MR slice. This provides immediate positional feedback to the neurosurgeon during the surgical procedure.

Videoconferencing: what are the benefits for dental practice?

For more than 3 years members of the TeleDent team from Bristol University have been looking at the potential of videoconferencing technology for dentistry. Here they explain what videoconferencing is and how it can help the GDP. They discuss examples of its most promising uses for the profession, which include professional updating and providing diagnostic support at a distance. They describe the equipment that is needed, the different types of system available and give an indication of costs. A suggested procedure for using the technology for remote referrals is outlined. 'Store and forward' techniques are also discussed. These do not involve a live video but involve the sending of static electronic files. This approach is compared with videoconferencing, and the article looks at the question of which will be best suited to the GDP, and for what purposes.

Intranets: virtual procedure manuals for the pathology lab.

A novel system exists for replacing standard written operation manuals using a computerized PC-based peer-to-peer network. The system design is based on commonly available hardware and software and utilizes existing equipment to minimize implementation expense. The system is relatively easy to implement and maintain, involves minimal training, and should quickly become a financial asset. In addition, such a system can improve access to laboratory procedure manuals so that resources can be better used on a daily basis.

Computer multitasking with Desqview 386 in a family practice.

Computers are now widely used in medical practice for accounting and secretarial tasks. However, it has been much more difficult to use computers in more physician-related activities of daily practice. I investigated the Desqview multitasking system on a 386 computer as a solution to this problem. Physician-directed tasks of management of patient charts, retrieval of reference information, word processing, appointment scheduling and office organization were each managed by separate programs. Desqview allowed instantaneous switching back and forth between the various programs. I compared the time and cost savings and the need for physician input between Desqview 386, a 386 computer alone and an older, XT computer. Desqview significantly simplified the use of computer programs for medical information management and minimized the necessity for physician intervention. The time saved was 15 minutes per day; the costs saved were estimated to be $5000 annually.

Computerized documentation of pharmacists' interventions.

A computerized system for documenting interventions, developed by the pharmacy department at a 695-bed tertiary care university teaching hospital, is described. A computerized system was developed to better gain the needed details on pharmacists' recommendations, to capture a greater number of such recommendations, and to prepare for recent changes in standards of the Joint Commission on Accreditation of Healthcare Organizations. Only clinically important recommendations or those that involve cost savings are documented. Data can be entered and retrieved from any medical information system terminal in the hospital, and each entry becomes part of the patient's permanent record. A hard copy of all recommendations and a data file are generated daily. Analysis of the data has provided numerous opportunities for improving both patient care and the quality of pharmaceutical services. The system has been well received by pharmacists and has resulted in physician support of pharmacists' recommendations, as well as substantial cost savings. A convenient, easy-to-use computerized program for reporting interventions has helped a pharmacy department conduct departmental and institutional quality assurance activities and decrease costs.
