The development of a virtual database to provide on-line access to a large archive of clinical data.

The archival database of the HELP Hospital Information System at LDS Hospital is too large to be stored on line. The archival data are important for clinical and research applications. Demountable disk packs have been used to store the archival database. This method of storage has four significant disadvantages. A virtual database was developed to overcome the limitations of this data-management scheme. This virtual database enables the transparent use of appropriate low-cost network-based storage technology to provide on-line availability of the entire archive of clinical data. The virtual database successfully resolves the problems associated with disk packs, and opens the door to enhanced use of the data for clinical and research applications.

Information storage for health-care providers: it's not as simple as it seems.

As medical practices migrate from paper to computers for record keeping, new issues surrounding the safe storage of such data are arising. These range from choosing an electronic storage format to ensuring that any electronic information stored today will be available and readable years into the future. Privacy and security issues also continue to be important, especially since the HIPAA regulations were instituted. With the rapid advances in technology, finding the right solution may be like trying to hit a moving target, yet some basic principles, outlined in this article, should make this difficult task easier.

Digital image storage.

Film has long been considered the gold standard for displaying and storing clinical images. But that may be changing. Digital technology--specifically digital imaging and storage technology--has advanced to the point where it can now deliver on the promises envisioned years ago. That is, the ability to provide any image, virtually anywhere, at any time--a goal that could never be achieved with film. Achieving this goal, however, requires a properly implemented digital infrastructure, including effective digital image storage. As early adopters will attest, digital image storage can be difficult to implement. It requires the careful selection and implementation of storage technologies and the continuous management of storage operations. In this Guidance Article, we address many of the issues facing the healthcare professionals charged with managing this process: We introduce the topic of medical digital storage, discussing how it is accomplished and why storing images is not that different from storing other forms of data. We review the available storage alternatives, from fast-access hard drives and RAIDs to long-term magnetic tape and optical disc storage. We delve into the issue of image compression, describing what compression is and how much can be used without affecting patient care. And we review the pertinent legal, regulatory, and management issues. When committing to a digital image workflow, it is essential that a healthcare facility give careful consideration to data storage issues, since poor choices can lead to significant long-term costs for the facility.

[Value of memory functions in implantable prostheses].

The development of memory functions with memorised electrogrammes is one of the most important technical advances in cardiac pacemakers and defibrillators. These memory functions are very useful in the management of patients with implanted prostheses. In the case of defibrillators, the memory allows evaluation and validation of appropriate treatments (shock or asymptomatic antitachycardia stimulation) or inappropriate function. The memory can also help assess the efficacy of complementary antiarrhythmic therapy or radiofrequency ablation. The incorporation of memory functions in pacemakers is more recent but no less useful. The latest generation of pacemakers have not only a therapeutic but also a diagnostic role with respect to atrial and ventricular arrhythmias. They can lead to the prescription of an antiarrhythmic or anticoagulant drug in cases of sustained atrial fibrillation confirmed by the memorised electrogrammes. The memory function is also a great aid in reprogramming stimulators in cases of overdetection (V-A cross talk). They may also be activated by the patient in cases of sporadic paroxysmal symptoms. The latest development is that of a purely diagnostic prosthesis: the implantable Holter, whose main indication is in the investigation of unexplained syncope.

[Building a SAN and NAS integrated storage system in hospitals].

We have recentely built a cluster and backup system based on a SAN + NAS integrated storage system at a low price. The integration of SAN + NAS provides a storage system of fine quality, high reliability and high stability for hospitals. The article mainly introduces the choice of the project, the design of SAN + NAS integration and its implementation.

Influences on the performance of hospital clinical event monitoring.

The implementation of real-time clinical monitors in large hospital information systems places large performance demands on these systems. Meeting these demands not only requires methodologies to augment the performance of individual monitors but an understanding of how patient population and monitor characteristics might influence overall system performance. We have built a multimonitor simulator to study these influences on performance. In doing so, we have focused on the impact of a variety of techniques to cache a subset of a large number of monitors in primary memory.

Smart Pharmacy Cards to automate patient records for prospective drug utilization review.

The Smart Pharmacy Card automates the patient's medical and prescription history so that every new prescription can be analyzed by a pharmacist to determine if it conflicts with disease states, allergies, prescription and non-prescription drugs documented in the card. The prototype that will be demonstrated at SCAMC 1991 will use an integrated-circuit card ("smart card") that holds 16,000 bits of electronically-erasable data.
