A 57-year-old male with unstable angina and an eccentric 88% diameter stenosis of the left anterior descending artery prior to, and involving the first diagonal branch was treated with the 2nd generation Jomed Sidebranch stent (Jomed, Randingengen, Germany). This case outlines the improvements in this novel stent design and demonstrates the rapid advance of device design.
OBJECTIVE: This paper aims to understand the nature of medical error in highly technological environments and argues that a comparison with aviation can blur its real understanding. METHODS: This study is a comparative study between the notion of error in health care and aviation based on the author's own ethnographic study in intensive care units and findings from the research literature on errors in aviation. RESULTS AND CONCLUSIONS: Failures in the use of medical technology are common. In attempts to understand the area of medical error, much attention has focused on how we can learn from aviation. This paper argues that such a comparison is not always useful, on the basis that (i) the type of work and technology is very different in the two domains; (ii) different issues are involved in training and procurement; and (iii) attitudes to error vary between the domains. Therefore, it is necessary to look closely at the subject of medical error and resolve those questions left unanswered by the lessons of aviation.
The Citizen Health System (CHS) is a European Commission (CEC) funded project in the field of IST for Health. Its main goal is to develop a generic contact center which in its pilot stage can be used in the monitoring, treatment and management of chronically ill patients at home in Greece, Spain, and Germany. Such contact centers, using any type of communication technology, and providing timely and preventive prompting to the patients are envisaged in the future to evolve into well-being contact centers providing services to all citizens. In this paper, we present the structure of such a generic contact center and present its major achievements, and their impact to the quality of health delivery.

The purpose of this study was to describe the support network of adolescents with a chronic disease from their own perspective. Data were collected by interviewing adolescents with asthma, epilepsy, juvenile rheumatoid arthritis (JRA) and insulin-dependent diabetes mellitus (IDDM). The sample consisted of 40 adolescents aged between 13 and 17 years. Interview data were examined using content analysis. Six main categories were established to describe the support network of adolescents with a chronic disease: parents, peers, school, health care providers, technology and pets. Peers were divided into two groups: fellow sufferers and peers without a chronic disease. At school, teachers, school nurses and classmates were part of the support network. Health care providers included nurses, physicians and physiotherapists. Technology was also part of the support network and included four techniques that may be used to communicate: computers, mobile telephones, television and videos. The results provided a useful insight into the social network of adolescents with chronic disease and serve to raise awareness of the problems and opinions experienced by adolescents with this condition.

Results from two studies of ethical dilemmas nurses and doctors experience on two high-technology units are compared and discussed. The qualitative comparative methodology of grounded theory was used to generate theoretical frameworks grounded in the empirical realities of the units. The ethical dilemmas they faced were related to: treating the one vs. the common good; end of life questions; and resource allocations with inadequate staffing. Similarities were related to intensity and urgency of nursing care and patient treatment, clear nursing ideologies based on treating humans within a framework of hope, embracing technology and scarce resources. Differences between the two study units were patient diagnosis, hierarchical structure on one unit while one had a vertical structure and decision-making processes, and finally how nursing knowledge and autonomy were used. The two studies demonstrated that clinical, ethical and administrative interactions and decisions are highly compounded, stressful and intertwined.
BACKGROUND: We examined clinical records of combat casualties that died subsequent to reaching a medical treatment facility in an effort to determine whether new medical technologies or enhanced training might contribute to a reduction in combat deaths. METHODS: Hospital records of 210 fatal combat casualties were independently reviewed by four surgeons. The surgeons assessed each fatality to determine whether it would be preventable if the trauma were sustained today and treated with currently available technology and training. RESULTS: In 8% of the cases, the four surgeons independently agreed that the deaths would be possibly preventable if the same traumas were incurred today. In an additional 17% of the cases, three of the four surgeons judged the deaths to be possibly preventable today. Causes of death viewed as most likely to be salvageable today included hemorrhage, severe burns, pulmonary edema, and sepsis. The medical technologies most often mentioned to have a potentially lifesaving effect were ventilators/respirators, computed tomographic scanners, ultrasound, and antibiotics. Areas of training most often mentioned to have a potential impact on the salvageability of the trauma cases reviewed were damage control, ventilator management, liver packing, respiratory distress management, and burn management. CONCLUSION: Surgeons reviewing records of past combat deaths indicated that reductions in the incidence of combat deaths through deployment of improved medical technologies and training is possible. Deployment of the noted technologies and proficiency in the cited training has the potential for reducing deaths by 8% to 25% when compared with the died-in-hospital incidence among casualties in the last sustained conflict.
Platelets play a central role in hemostasis and wound healing. The latter is mediated by release of secretory proteins on platelet activation, which directly or indirectly influences virtually all aspects of the wound healing cascade. Studies in basic science have shown a dose-response relationship between the platelet concentration and levels of secretory proteins, as well as between platelet concentration and certain proliferative events of significance to the healing wound. Technologies to provide autologous platelet rich plasma to the repair site are now being used in a wide variety of clinical applications, with the majority of such studies suggesting a role in the surgeon's armamentarium. Little standardization in the field exists, which has made it difficult to fully evaluate the literature on the subject and unequivocally establish applications for which the technology truly has merit. This article presents fundamental background on platelet biology and the role of platelets in both hemostasis and wound healing, as well as methods of preparing, characterizing, and using platelet rich plasma, to provide the reader a foundation on which to critically evaluate prior studies and plan future work.
Improvements in the provision of oxygen, mechanical ventilation, tracheostomy care, enteral and parenteral nutrition, and dialysis have expanded the population of technology-dependent children. This article attempts to review pertinent points regarding these services, including common complications. Primary care and subspecialty physicians must smooth the transition of these children to the home environment, but a comprehensive team approach is necessary for the recognition of medical complications and provision of appropriate family teaching and psychosocial supports.

The practice of medicine is inherently dependent upon health technology. Clinicians use a wide variety of technologies in diagnosing, treating, and assessing the care of their patients. In this book, The Future of Health Technology, many different aspects of health technology are discussed in detail. Considering this breadth of coverage, it is challenging to ascertain what remains to be discussed in this chapter on "the future of medical computing". Given this considerable coverage, this chapter will open with a brief vision of the future of medical computing from three perspectives--the Patient, the Ambulatory Provider, and the Hospitalist. Discussion follows on the current and future driving forces for change in healthcare technology, and an overview of the unresolved issues that must be addressed. Necessarily, this chapter will not provide more than an overview of these topics and issues. Rather, it is the author's intent to present several visions of the future of medical computing and outline the issues, which must be overcome to achieve the vision.
The precautionary principle has its origins in debates about environmental policy, but is increasingly invoked in bioethical contexts. John Harris and Søren Holm argue that the principle should be rejected as incoherent, irrational, and representing a fundamental threat to scientific advance and technological progress. This article argues that while there are problems with standard formulations of the principle, Harris and Holm's rejection of all its forms is mistaken. In particular, they focus on strong versions of the principle and fail to recognize that weaker forms, which may escape their criticisms, are both possible and advocated in the literature.
Hospital use and spending greatly increased in 2001 and 2002, reversing a long-term trend. In this paper we contend that the forces driving current hospital expenditures are more likely to continue than they are to abate. If current trends continue, real hospital spending per capita will increase 75 percent between 2002 and 2012, and the demand for hospital beds will increase considerably. We discuss numerous forces that will contribute to spending growth, including technology, which is likely to continue to raise costs. We also find that hospital spending by baby boomers grew more rapidly than that of the elderly, a change in trend that could presage increased spending as this cohort moves into higher-spending age groups.
AIM: This paper presents a new theoretical model to explain people's diverse responses to therapeutic health technology by characterizing the relationship between technology dependence and health-related quality of life (HRQL). INTRODUCTION: Technology dependence has been defined as reliance on a variety of devices, drugs and procedures to alleviate or remedy acute or chronic health problems. Health professionals must ensure that these technologies result in positive outcomes for those who must rely on them, while minimizing the potential for unintended consequences. Little research exists to inform health professionals about how dependency on therapeutic technology may affect patient-reported outcomes such as HRQL. Organizing frameworks to focus such research are also limited. MODEL: Generated from the synthesis of three theoretical frameworks and empirical research, the model proposes that attitudes towards technology dependence affect HRQL through a person's illness representations or commonsense beliefs about their illness. Symptom distress, illness history, age and gender also influence the technology dependence and HRQL relationship. Five concepts form the major components of the model: a) attitudes towards technology dependence, b) illness representation, c) symptom distress, d) HRQL and e) illness history. CONCLUSION: The model is proposed as a guide for clinical nursing research into the impact of a wide variety of therapeutic health care interventions on HRQL. Empirical validation of the model is needed to test its generality.
