    Fibrosis of biosensors, placed in vivo, represents a major hurdle to the wide-spread application of real-time monitoring of biochemical and metabolic processes in animals and humans. The fibrotic reaction is the end result of the acute inflammatory response caused by significant tissue trauma at the time of biosensor placement. This response may be associated with increased expression and release from cells of cellular stress proteins. We tested the hypothesis that subcutaneous injection of stress proteins will cause acute inflammatory swelling in an in-vivo murine model. Comparisons between groups were performed using the Dunnet T3 multiple comparison test and significance was accepted when p < 0.05. Subcutaneous injection of stress proteins (HSP70 or GRP78) was associated with significantly increased acute swelling in comparison to injections of saline or autologous serum (AS). The histological analysis demonstrated increased inflammatory cell infiltrate in the tissues that received the stress protein injections. Stress proteins, within the acute wound environment, are proinflammatory and may set the stage for peribiosensor fibrosis and eventual failure. Stress proteins may be future targets for therapeutic manipulation wherever acute inflammation is followed by problematic fibrosis. View full abstract»

    Independent, multihospital clinical engineering organizations have existed for 30 years. The clinical engineering profession has changed its focus over this time from equipment safety and control to healthcare technology management. Challenges faced by the professional have included cost pressures, outsourcing, and medical device industry changes. This paper describes an enduring independent, nonprofit, multihospital clinical engineering organization, the Technical Services Program (TSP) at the University of Vermont, which shows a successful adaptation to challenges. As part of TSP's five-year strategic plan, a strategy for changing these challenges into opportunities is part of the goal. Our clinical engineers have to be fluent in both information technology and biotechnology, follow trends in patient care technology and act accordingly, understand new customers and effectively deal with their technology problems, partner with manufacturers in technology support and planning, use failure analysis tools to effectively reduce technology-related patient incidents, and understand business and quality principles and apply them to make healthcare more cost effective. Current and future healthcare system changes are opportunities for the profession and fit well into the independent, multihospital mission of TSP. View full abstract»

    This article discusses a healthcare technology assessment application using a well-developed business tool from the operations research/operations management (OR/OM) field, the analytic hierarchy process (AHP). The AHP methodology provides a proven, structured, and well-documented tool for conducting HTAs for hospitals, integrated delivery networks, or other healthcare providers. A case study based on the selection of a neonatal ventilator is used to illustrate a successful use of the AHP for HTA. Clinical engineers can use this design as a prototype for performing HTAs in their own institutions. View full abstract»

    A minisystem is the smallest system that can deliver a single clinical benefit. Healthcare is delivered to patients through an assemblage of minisystems. It is the failure of these minisystems that reportedly results in between 44,000 and 98,000 iatrogenic deaths in the United States annually. Accident investigations are intended to identify the latent defects within these minisystems and to recommend corrective actions that will prevent a recurrence. Since human error is involved in approximately 69% of these deaths, understanding the fundamental causes of human error is important to an effective investigation. Device-related accident investigations require a three-step process to identify the deficiencies: 1) gathering clinical and engineering data surrounding an event, 2) analyzing the data to identify the components of the minisystem that contributed to the event, and, when operator error is identified, 3) translate the clinical actions of the operator to human error concepts. A case study of an incident involving a defibrillator which illustrates the process and recommendations for adjusting the minisystem to increase compatibility with the device operator are presented.

    The primary goal of this study is to quantify the communications reliability of telemetry systems using ISM-band two-way communications technology and contrast it to that of VHF/UHF-based systems from an empirical and clinical perspective. The principal criterion variable of communications reliability was total dropout proportion: the percentage of wireless patient monitoring time attributable to a loss of patient signal. Data from 17 institutions across the United States were included in this research. The data from this study were also used to explore potential relationships between communications reliability and various institutional factors. The institutional variables evaluated for possible adverse impact on ISM-band communications reliability included wireless coverage area, the number of telemetry transmitters supported, institutional experience with the product, gross institution size, and the number of telemetry systems within each hospital. The frequency-hopping communication technology utilized by the ISM-band products was not adversely affected by coexisting ISM-band devices. Institutions with shared ISM-band environments demonstrated a better - but statistically insignificant - performance difference both in terms of total dropout proportion and mean time between dropouts. Analysis showed no adverse affect on the communications reliability of ISM-band systems as a function of the number of telemetry transmitters supported, institution size, number of ISM-band telemetry systems within an institution, coverage area, or institutional experience with the system. In contrast, VHF/UHF installations showed statistically significant adverse impact on dropout proportion from two sources: the more transmitters supported, or the greater the coverage area, the higher the dropout proportion. The results from regression analysis at the institution-level should be interpreted cautiously since the statistical power was limited by the number of hospitals in the sample. View full abstract»

    Coupling computational modeling and information processing in biology and medicine is a major challenge for better comprehending structures and functions of living systems. Signal processing should extract the relevant information required to explore complex organization levels, at all space and time scales. Advances coming from applied physics and mathematics are challenged by extremely hot topics in biology and medicine. The biomedical scene has proven to be the most difficult to address due to the fact that biomedical processes involve nonGaussian, nonlinear, and nonstationary components. This paper provides some clues on processing schemes such as time and frequency transforms, blind signal separation, independent component analysis, empirical mode decomposition, particle methods and Kernel methods that may help in lessening the ambiguity about the observed components of the mixtures to be handled and, this way, facilitating their matching with models.

    The majority of clinical engineers serve as part of the healthcare team along with physicians, nurses, technologists, and other hospital staff. The clinical engineer's role is to insure that other team members have adequate and effective technology for the time delivery of quality healthcare. In essence, clinical engineers must act as the "stewards" of healthcare technology. As effective stewards, clinical engineers need to understand the practitioners' intent, they need to possess knowledge with respect to both existing and developing healthcare technology, and they must also understand the various implications of applying the technology. Only when forearmed in this manner can clinical engineers hope to serve as successful stewards and help insure healthcare technology is applied for the greatest benefit. The implications of technology adoption and integration between diagnostic, information processing, and therapeutic systems are discussed. View full abstract»

    Information technology offers medical science tools to collect, process, store, and communicate clinical data. Healthcare institutions have adapted standards-based data communication technologies that allow easy implementation of communications infrastructure. As clinical and information technologies have converged, two trends have emerged: the widespread use of commercial off-the-shelf hardware and software and the use of standards-based communication technologies. Technical support for these complex systems requires an integrated, "end-to-end" view and staff who are knowledgeable of both clinical and computer technologies. In this article, examples of new computerized medical devices are discussed as well as the support and support staff implications of the ever-growing influence of IT on clinical systems.

    The appropriate deployment of technology contributes to the improvement in the quality of healthcare delivered, the containment of cost, and to increased access to services offered by the healthcare system. Over the past one-hundred years, the dependence of the healthcare system on medical technology for the delivery of its services has continuously grown. In this system, the technology facilitates the delivery of the "human touch." Medical technology enables practitioners to collaboratively intervene together with other caregivers to treat patients in a cost-effective and efficient manner. Technology also enables integration and systems management in a way that contributes to improvements in the level of health indicators. Hospital and clinical administrators are faced with the expectation for return on investment that meets accounting guidelines and financial pressures. This article describes the emerging process for managing medical technology in the hospital and the role that clinical engineers are fulfilling. View full abstract»
