A teleradiology architecture featuring security and high performance.

DSL or cable modem promise faster teleradiology solutions but require security measures to protect data as it travels over the public Internet. A Virtual private network link may protect data but creates a vulnerability for the hospital intranet. We upload images from the hospital to Web server hosted on the Internet and download them to a PC at the physician's home. Both transfers are protected by the standard SSL Web security protocol. Files can be zipped together for transmission as a unit, with lossless compression as an added benefit. We have measured download times of a few seconds for nuclear medicine studies and a few minutes for a computed tomography study. The proposed solution, which does not require a full-fledged picture archiving and communication system, is adequate for small hospitals or imaging centers.

IHE: a model for driving adoption of standards.

The development of communication standards in healthcare is a major ongoing engineering effort. While there is little doubt that this effort has made possible significant advances in the performance of healthcare information and imaging systems, overall levels of systems interoperability have not improved as dramatically as one might reasonably expect and the cost of implementing effectively integrated systems remains high. The lag between the development of information standards and their implementation in real systems and institutions is a genuine problem in healthcare. This paper describes an ongoing initiative that attempts to bring together healthcare professionals and industry experts to coordinate the implementation of standards in ways that enhance operational efficiency and the quality of patient care.

Hospital goes on-line with electronic medical record.

In May, Texas Children's Hospital in Houston went live with a pilot project to test the use of electronic medical records at the facility. Currently, the system is available for use by clinicians in selected units who have access to results data. In the hospital's cancer center, a related pilot program has physicians and nurse practitioners entering their clinical notes and order sets electronically, cutting out the need for transcription. Project leaders emphasize that achieving physician buy-in has been crucial to the success of the project, especially as electronic notes and order sets become standard throughout the hospital.

Patient-provider connectivity and the role of e-health.

Patient-provider connectivity (PPC) offers innovative approaches to control costs, improve quality, and sustain a healthy workforce. The application of e-commerce to health care is one facet of PPC and provides solutions to educating, informing, and more efficiently using scarce resources to sustain the nation's health. Technology is available to provide real-time access to clinical results, medical records, health-care providers, and other time-sensitive patient information. This is the first article in a series on PPC that explores the application of e-commerce to the health-care industry from the consumers' and providers' points of view and examines and assesses trends and data from various interdisciplinary sources and studies. Two models exemplifying PPC are explored including the Science Business & Education, Inc., proof-of-concept patient demonstration project, and the emerging application of peer-to-peer (P2P) technology. PPC promises to improve efficiency, facilitate communication between physician and patient, monitor compliance with medical regimens, and positively affect the quality of health care provided and the overall health of the patient. Future articles will address the growth of telemedicine, issues of confidentiality and e-risk, and other PPC applications.

Informatics in the service of health, a look to the future.

The paper attempts a balanced look at the directions of health informatics required in the future. In a high level review of impediments to health and health care a number of issues are identified that may be amenable to improvement by contributions from health informatics. Attention is drawn to the improvement of the collection and dissemination of knowledge in addition to the analysis of morbid conditions as a focus for health informatics. On this basis a review of the current state of health information systems is undertaken. The importance of adaptable user interfaces for end users and systems personnel, privacy and confidentiality protection, and linkage among clinical support systems and knowledge repositories is stressed. These improvements hinge on advancements in medical concept representation. Canadian contributions to these developments, particularly the instigation of Evidence Based Medicine (EBM) are briefly reviewed.

Optical security system for the protection of personal identification information.

A new optical security system for the protection of personal identification information is proposed. First, authentication of the encrypted personal information is carried out by primary recognition of a personal identification number (PIN) with the proposed multiplexed minimum average correlation energy phase-encrypted (MMACE_p) filter. The MMACE_p filter, synthesized with phase-encrypted training images, can increase the discrimination capability and prevent the leak of personal identification information. After the PIN is recognized, speedy authentication of personal information can be achieved through one-to-one optical correlation by means of the optical wavelet filter. The possibility of information counterfeiting can be significantly decreased with the double-identification process. Simulation results demonstrate the effectiveness of the proposed technique.

[Standards for safe data exchange in teleradiology exemplified by image and report distribution].

The use of telemedicine is becoming indispensable for a continuous and economical delivery of a high quality of care. However, data protection requirements have to be considered. For the selection of solutions, vendor-independent components based on standards are a prerequisite for a seamless integration into the existing, often heterogeneous, IT infrastructure. The "Internet protocol" TCP/IP and the DICOM standard with it's new security extensions form the basis for an internationally standardized and accepted procedure for a secure interchange of radiological images beyond platform boundaries.

Unique patient concept: a key choice for European epidemiology.

The French Ministry of Health is setting up the personal medical record (PMR or DMP for Dossier Médical Personnel in French). This innovating tool is highly expected and will be extremely useful for the therapeutic follow-up as well as for epidemiological studies on which public health policies are based. Therefore the currently planned identifying process should prevent any epidemiological use of these data. Numerous scientific organisations have alerted government powers about the threat that this impairment represents, and they wish to promote some secure procedures that exist, which have already proved their efficiency at the national and international level.

An internet web site as a data collection platform for multicenter research.

The Internet can be an effective alternative for data collection for multicenter studies. It has major advantages over the "classical" method of using paper and traditional ("snail") mail. We developed an Internet site and implemented collection of data for a multicenter study of ethical decision-making. The Web site was built with Microsoft FrontPage as the authoring tool. Database management was performed with Microsoft Access. Security issues were the major concerns for the web design. Thirty-seven European centers enrolled 4248 patients during 1.5 yr using the Internet site. The use of this Internet site for data acquisition was highly effective, and the investigators were able to use the system without training. Overall satisfaction of the investigators was high. After security issues, interactivity and user-friendly design are the main cornerstones for the success of such a system.

Security aspects of teleradiology between the university centre and outlying hospitals in Tyrol.

We assessed a data security system using biometric fingerprint techniques and smartcards to control access to a teleradiology system. Clinical cases were initially discussed between the referring physician and radiologist in Tyrol using a video-phone. Subsequent correspondence, including the transmission of images between the referring physician and the radiologist, was carried out by e-mail using the security system to prevent unauthorized access to patient information. Seventy-eight teleradiology sessions were conducted using this data security system. Speed and stability of data exchange were unaffected by the additional security feature. The average log-on time to the system was 7.8 s. The average training time on how to use the system was 15 min. The radiologist was able to issue a final patient report using the system within 1.5 of the initial contact. The data security feature was user-friendly and did not hinder the normal teleradiology consultation.

Use of a Web-based process model to implement security and data protection as an integral component of clinical information management.

Delivery of health care at Scott and White, a large integrated health care delivery system, is supported by an Electronic Medical Record (EMR) system repository of six million SGML-based documents. Control of document access is currently based on standard commercial security and confidentiality methodologies. Given the planned release in Fall 1999 of new federal security and confidentiality requirements, we have developed a web-based security process model that "wraps" existing EMR documents with HTML-compliant security attributes. Resulting logical documents are filtered regarding user queries by mapping the security attributes of the data to specific user role characteristics. A key virtue of our approach is that source EMR data do not undergo alteration by the imposition of the security process. It also places no additional work load or query pressure on the existing EMR system.

A proposed key escrow system for secure patient information disclosure in biomedical research databases.

Access to clinical data is of increasing importance to biomedical research. The pending HIPAA privacy regulations provide specific requirements for the release of protected health information. Under the regulations, biomedical researchers may utilize anonymized data, or adhere to HIPAA requirements regarding protected health information. In order to provide researchers with anonymized data from a clinical research database, we reviewed several published strategies for de-identification of protected health information. Critical analysis with respect to this project suggests that de-identification alone is problematic when applied to clinical research databases. We propose a hybrid system; utilizing secure key escrow, de-identification, and role-based access for IRB approved researchers.

Overcoming diverse security protocols across institutions to enable convenient file-sharing and videoconferencing among collaborators.

The use of videoconferencing and file sharing tools among colleagues at large institutions has traditionally been confounded by differing security policies in place at each location. Building an electronic collaboration infrastructure based upon the lowest-common-denominator security configuration expected to be encountered will yield an accessible collaboration environment previously unavailable to geographically diverse researchers and clinicians.

Security and legal issues associated with the computerized patient record.

The advances in electronic technology in the form of increased processing power, the ability to computerize many aspects of a patient's record, and the emergence of document imaging systems and telemedicine have enhanced health care professionals ability to more accurately document care. However, with this augmentation comes issues in liability and security of which professionals should be aware. This article discusses some of these issues from the viewpoint of the perioperative nurse.

A remote data access architecture for home-monitoring health-care applications.

With the aging of the population and the increasing patient preference for receiving care in their own homes, remote home care is one of the fastest growing areas of health care in Taiwan and many other countries. Many remote home-monitoring applications have been developed and implemented to enable both formal and informal caregivers to have remote access to patient data so that they can respond instantly to any abnormalities of in-home patients. The aim of this technology is to give both patients and relatives better control of the health care, reduce the burden on informal caregivers and reduce visits to hospitals and thus result in a better quality of life for both the patient and his/her family. To facilitate their widespread adoption, remote home-monitoring systems take advantage of the low-cost features and popularity of the Internet and PCs, but are inherently exposed to several security risks, such as virus and denial-of-service (DoS) attacks. These security threats exist as long as the in-home PC is directly accessible by remote-monitoring users over the Internet. The purpose of the study reported in this paper was to improve the security of such systems, with the proposed architecture aimed at increasing the system availability and confidentiality of patient information. A broker server is introduced between the remote-monitoring devices and the in-home PCs. This topology removes direct access to the in-home PC, and a firewall can be configured to deny all inbound connections while the remote home-monitoring application is operating. This architecture helps to transfer the security risks from the in-home PC to the managed broker server, on which more advanced security measures can be implemented. The pros and cons of this novel architecture design are also discussed and summarized.
