The diffusion and use of diagnostic imaging equipment in France. The limits of regulation.

The paper presents a French national survey on diagnostic imaging equipment and activity showing that conventional x-ray radiology still dominates and that the rate of diffusion of technological innovations has been very different, being slower than in other industrialized countries for such technologies as CT scanners, nuclear medicine, and magnetic resonance imaging, but on the other hand, very quick for ultrasound and digital angiography. The variety of regulations for this equipment, although it plays an important role, is not sufficient to explain these differences in the rate of diffusion. The paper shows that other explanatory variables must be taken into account, at least in the French context: the situation of the domestic biomedical industry, the relations between private and public sectors of health care delivery, and even the "technical" culture and tradition of French radiologists.

Evaluation of diagnostic imaging technologies and therapeutics devices: better information for better decisions: proceedings of a multidisciplinary workshop.

We are entering an era in which the success of biomedical science and the increasing understanding of the value of evidence for practice are in a state of tension. This tension is especially notable in the device arena, in which the short life cycles and iterative nature of development are at odds with current design constructs of the types of clinical trials that provide evidence for medical decision making. The financial pressure arising from strained budgets and expanding costs from the aging of the population and the continued development of new technology heightens the need for a focus on new approaches. Given this background, a group of experts representing constituencies with different perspectives were convened for a day and a half to discuss key issues and their potential solutions. Because of the complex and heterogeneous nature of the environments in which devices are used, the meeting focused on 3 broad, general uses of devices: imaging, risk stratification, and therapeutics. The goal of the meeting was to develop a preliminary list of ideas that could be framed as researchable questions or constructs for consideration by policy makers that ultimately might lead to improvements in the current system. Across diagnostic imaging, risk stratification devices, and therapeutic devices, the crosscutting issues can be identified: We need better methods of collaborative funding and priority setting, improved and more flexible methods, and new approaches to the integration of federal agencies in overseeing the system.

Technological developments and approaches to improving service quality.

In summary, major paradigm shifts in the health care industry are altering the way technology is maintained and supported. Service organizations are now responsible for maintaining a broader base of technology within the health care delivery network and must to this on an extremely rapid, efficient, and productive basis. A number of new technologies are coming on-line, which can allow a health care technology service organization to experience significant improvements in profitability, efficiency, and productivity. To realize maximum benefit from these technologies, service organizations may find themselves re-engineering their service processes. The author believes that this is a requirement for many service organizations, regardless of whether new technology is implemented. The traditional approaches to service delivery are ineffective in managing the new structural realities and service requirements of today's health care environment. New strategies and tactics are required for ensuring that these requirements are met. These approaches will no doubt improve the overall quality, productivity, and efficiency of service and are based on best practices utilized by leading OEMs and ISOs in the medical electronics and other high technology service industry such as information technology and telecommunications, where the service organization is responsible for supporting a broad array of the technology over a large geography with a densely populated installed base, not unlike the typical health care delivery service environment. Once operational improvements are made, a service organization can take advantage of the productivity and efficiency gains brought on by new technology. Organizations interested in doing so are urged to thoroughly research the current state-of-the-art and best practices, because there are numerous systems currently available off-the-shelf. The author believes that new technology will be a basic requirement for competing in the health care technology service marketplace, because it can significantly affect the profitability of service organizations. This technology will help level the playing field between ISOs, OEMs, and biomedical personnel. As our research suggests, efficiently operating biomedical personnel can achieve a significantly higher utilization and profitability than efficiently operating OEMs, due to the advantages of lower overhead and operating cost structure. In general, the process to improve service productivity and efficiency involves a review of current service operations and understanding of the customer environment perceptions as well as understanding of key service factors parameters. From there, service organizations should identify the current state-of-the-art service and infrastructure systems and technology. Based on this assessment, a service organization can evaluate best practices and identify new strategies and tactics for improving service delivery. Through better service management control and education of users on the improvement in service, which the new processes and technologies provide, the service organization can realize real, quantifiable improvements in service quality, productivity, and profitability.

The freedom and the responsibility of investigator-initiated research.

Since World War II, scientific inquiry and research have been based on the premise that the more investigator-initiated research is conducted, the more automatic benefits for society are created. It is finally becoming clear to many that this belief is neither rational, true, nor healthy; in short, we as a society have been indiscriminately embracing whatever we are able to do instead of doing those things that will take society where it needs to go. Trickle-down science and technology do not work any better than the famous trickle-down economics worked. The author praises the accomplishments of scientific research but gives several examples, including those involving health care, of the widening gap that unguided science and technology have helped to foster between the advantaged and disadvantaged populations in most of the world, including the United States. He proposes that while investigator-initiated research is crucial, it must be done in the context of strategic paths and a set of values that direct it toward achieving the goals for the nation and the world that must be reached if the planet and its increasing population are to survive. He emphasizes that such strategic paths provide the compass; they do not control the journey. For example, he is not saying that biomedical researchers should be directed to specific experiments, but rather that as researchers they must realize the moving from remediation to prevention is a primary national and international goal for human health.(ABSTRACT TRUNCATED AT 250 WORDS)

NIH-FDA Analgesic Drug Development Workshop: translating scientific advances into improved pain relief.

Analgesic drug development as currently undertaken is limited by a number of factors that contribute to the paucity of new analgesics introduced into clinical practice despite marked advances in delineating of the molecular-genetic mechanisms contributing to acute and chronic pain. The participants in this workshop explored the unmet need in analgesia and recommended strategies for enhancing analgesic drug development in the future. The workshop concluded that translating scientific advances into improved pain relief will require new thinking and a cooperative effort among the pharmaceutical industry, regulatory agencies, funding agencies, the biomedical research community, professional societies and clinicians. The workshop also recommended that a better understanding of the epidemiology of pain could contribute to improvement in clinical trial methodology and outcome measures.

Perspectives of new reproductive and diagnostic techniques among biologists and physicians, social scientists and ethicists.

The introduction and acceptance of new techniques in the field of reproductive medicine and antenatal genetic diagnosis is a complicated process in which biomedical professionals, and also social scientists and ethicists, play an important role. In this study the attitudes, expectancies and opinions of a panel of biological and medical professionals working in the field of this new technology are compared with those of a panel of concerned social scientists, psychologists, ethicists and leading members of patient groups. Various aspects of the new techniques are investigated: the present and future feasibility, the potential importance, the ethical evaluation and the social acceptance. The social-ethical panel appears to be much more reluctant regarding the importance, ethical values and social acceptability of new techniques than the biomedical panel, in particular, for preimplantation genetic diagnosis and fetal cell sorting large differences exist.
