Ending the technology paradox: healthcare management technologies for clinical decision making.

As this article has shown, advances are beginning to put an end to the technology paradox that has hindered the industry's efforts to manage care better. Whereas in the past the management side of the healthcare industry has been slow to adopt new technologies, recent years have seen an explosion in the development and use of new tools for managing care. Most of these tools have traditionally focused on managing the administrative and financial aspects of providing care; however, that has also begun to change. Software systems incorporating clinical decision support criteria permit healthcare professionals to make clinical decision-making part of the care management process conveniently and efficiently. Clinical decision support criteria are also helping to change the focus of managed care. At the beginning of the managed care era, insurers and managed care companies concentrated primarily on reigning in costs, in many cases by restricting the types and duration of care provided to their members. Although these restrictions succeeded in conserving resources, they also helped foster an uneasy atmosphere between payers and providers, many of whom felt that their clinical judgment was too often overruled by the "bean counters." At the same time, many healthcare consumers grew to distrust both managed care professionals and providers, feeling that medical decisions were often made for the wrong reasons. However, as managed care companies have acknowledged that the most efficient way to provide care is to provide appropriate care, the focus has begun to move toward the clinical side of healthcare. Although healthcare organizations are still relying on financial management tools, they are also looking for systems that can make the clinical decision-making process more efficient and effective. The end result is that the healthcare industry is able to assure the best, most appropriate treatment while conserving resources. With the constant stream of new technologies into the healthcare management arena, healthcare professionals will have access to new tools to make the management process even more efficient. The healthcare industry's technology paradox will soon be a thing of the past.

Universal design and assistive technology in communication and information technologies: alternatives or complements?

Universal design and assistive technology present advantages and disadvantages in accommodating the needs of people with disabilities. The best solution may be a combination of the two, using universal design wherever possible and commercially practical and using assistive technologies wherever it is necessary or provides sufficient additional advantage to the user. Three approaches are discussed for the individual who is unable to interact with their world: change the individual, provide them with tools they can use, or change the environment. Examples of each are illustrated using personal workstations and shared, public, and encountered systems. The final decision may rest on commercial practicality, and several new technologies are explored. Ultimately, we need to continue to move forward both on the universal design and the assistive technology fronts if we are to address the needs of people with disabilities and those who are aging.

A model for technology assessment applied to pulse oximetry. The Technology Assessment Task Force of the Society of Critical Care Medicine.

OBJECTIVES: To test a model for the assessment of critical care technology. To develop practice guidelines for the use of pulse oximetry. DATA SOURCES: A computer-assisted search of the English language literature and interviews with recognized experts in the field of pulse oximetry. STUDY SELECTION: Those studies that addressed one or more of the seven questions contained in our technology assessment template were analyzed. Study design was not a factor in article selection. However, the lack of well-designed clinical outcome studies was an important factor in determining the method of practice policy development we utilized. DATA EXTRACTION: A focus person summarized the data from the selected studies that related to each of the seven assessment questions. The preliminary data summary developed by the focus person was further analyzed and refined by the task force and then sent to 16 expert reviewers for comment. These expert comments were considered by the task force, and this final consensus report was developed. DATA SYNTHESIS: Pulse oximetry combines the principles of spectrophotometry and plethysmography to noninvasively measure oxygen saturation with a high degree of accuracy over the range of 80% to 100% saturation, assuming the device is being used according to the manufacturer's instructions and without any adverse operating conditions. The appropriate clinical uses of pulse oximetry fall into one of two broad categories: as a warning system based on continuous real-time measurement of arterial desaturation, or as an end-point for titration of therapeutic interventions. There are no published studies that allow for definitive, outcome-based conclusions concerning either the clinical impact or cost-benefit ratio of pulse oximetry. CONCLUSIONS: The model developed for technology assessment proved to be appropriate for assessing pulse oximetry. The available data have allowed us to develop an evidence-based practice policy for the use of pulse oximetry in critical care. Critical care clinicians, researchers, and industry have a shared responsibility to provide valid outcome and efficacy studies of new technologies.

Technology anxiety as a potential mediating factor in response to medical technology.

Technology anxiety, defined as a fear of working with medical equipment, was measured via the use of the Technology Response Questionnaire. Nurses (N = 414) working on nine types of nursing units at two hospitals participated in the study. Nurses working on psychiatric units were found to be most anxious about working with medical equipment, while nurses working on surgical and adult intensive care units were least anxious. A comparison of the nurses who were highest and lowest on technology anxiety indicated that those who were most anxious about technology were less positive toward computers, felt more stressed by their work, were lower on job satisfaction, less positive toward the physicians they worked with, lower on personality scales of autonomy and adaptability, were less likely to do care planning regularly or to use nursing diagnoses, and tended to be older than less anxious nurses.

From computer technology to information technology. Findings from a national study of nursing education.

A research survey was conducted on a stratified random sample of National League for Nursing accredited diploma, associate, baccalaureate, and master programs to determine the status of computer and information technology in nursing education. Fifty-five percent (n = 190) of the 347 selected schools responded. Compared with national statistics, all programs (diploma, associate, and higher degree) were proportionately represented. Findings indicated that schools have almost universal access to computers and educational software. However, further data analysis indicated that a majority of schools lacked a coordinated plan for technology implementation and were underfinanced for technology and related personnel. In addition, less than one third of the schools addressed nursing informatics (the information of nursing) in the curriculum and only 19 schools indicated that nursing informatics was offered as a separate course. Successful strategies for the implementation of computer and information technology are presented based on the findings.

Current status of economic appraisal of health technology in the European Community: report of the network. The EC Network on the Methodology of Economic Appraisal of Health Technology.

The use of economic evaluation to assess the costs and consequences of health care technologies has steadily increased in recent years. However, little is known about the influence economic studies have on health care decision makers or policy at local and national level. This paper reports the results of a survey of economic evaluations in EC countries to identify the impact of the results on decision and policy making in health care. Health service researchers in 10 EC countries were identified and asked to participate in the survey. The researchers were asked to locate economic evaluations in their country and complete a standardised questionnaire for each study. The criteria for inclusion in the survey were first, the studies should have been started or reported since 1987, second, the evaluations should include a comparison of the cost and consequences of the technologies assessed and finally, the appraisals should include a comparison of alternative health care technologies or programmes. A total of 66 studies which met the survey criteria were reported. Of these, 27% were thought to have influenced health care decision makers or policy. The results suggested that method of dissemination, source of funding and purpose of the study may be important determinants of whether an economic evaluation will be used in health care policy or decision making. The results of the survey suggest that economic evaluation currently has a relatively low impact on health care policy or decision making.(ABSTRACT TRUNCATED AT 250 WORDS)

International collaboration in health technology assessment: a study of technologies used in management of osteoporosis.

A collaborative study was undertaken by members of the International Network of Agencies for Health Technology Assessment (INAHTA). The evidence of the effectiveness of bone density measurement and selected treatments in preventing fractures in later life was reviewed. There was fair evidence that bone density measurement can predict risk of fractures and that hormone replacement therapy and intranasal salmon calcitonin preserve bone mass and decrease the risk of fractures. However, it was estimated that only 1-7% of hip fractures would be prevented if these technologies were used in a screening program for menopausal women. Results of the assessment were endorsed by 13 INAHTA members, disseminated widely and provided input to policy and further work in this area. The project demonstrated the feasibility of international collaborative health technology assessment.

Medicare payment for new technologies. Can the process be improved despite conflicting goals? An ECRI technology management assessment.

Decisions about Medicare payment for new technologies are made by a multiagency process that became even more complex with the advent of DRG-based payments for inpatient care. Numerous problems with this decision-making process are widely acknowledged to exist but difficult to solve because of inherent conflicting goals. This report proposes consideration of basic improvements to the process, including: increased support for clinical and cost studies, particularly from manufacturers of new technologies; approval of provisional payments to providers who agree to collect effectiveness and cost data; additional research into technology assessment methods; clarification of decision-making criteria; opening of the coverage-decision process to greater public scrutiny; according more weight to recommendations of the Prospective Payment Assessment Commission; submission of additional data to the Food and Drug Administration; and increasing the flow of information among Medicare coverage-decision agencies and other third-party payers. Many of these modifications can be accomplished without congressional action, if the interested parties are willing to work together to improve the coverage-decision process.

Court-ordered reimbursement for unproven medical technology. Circumventing technology assessment.

OBJECTIVE--Because we found examples where courts of law ruled against insurance carriers that had been sued for reimbursement for unproven medical procedures, we conducted a case study to determine the reasoning behind these decisions that run counter to accepted medical science. Such actions circumvent health technology assessment and could contribute to escalating health care costs and poorer quality health care. DATA SOURCES--A literature search identified 17 cases between 1980 and 1989 in which an insurance company was sued to reimburse a patient who had received an unproven or questionable health technology; 14 of these suits were decided in favor of the plaintiff, and the insurance company was ordered to pay. Discussed in this article are six of these cases, two involving Laetrile (amygdalin), two involving immunoaugmentative therapy, and two involving thermography, technologies that had previously been assessed as not safe, not effective, or inadequately evaluated. DATA SYNTHESIS AND CONCLUSIONS--The circumstances determining how the courts arrive at these "unscientific" decisions fall into three general categories: (1) for legal reasons, the insurance contract is interpreted in favor of the insured; (2) the reluctance and/or inability, legal or otherwise, of the courts to use published scientific literature; and (3) the use of adversarial "expert" witnesses with potential conflicts of interest. To address this situation, we first urge the legal and insurance industries to cooperate in improving the contract language and process in a way that would be both legally and scientifically appropriate. Second, we encourage the courts to use and foster the use of published peer-reviewed scientific material as evidence whenever possible. Third, we recommend that the courts choose their own unbiased expert witnesses to interpret scientific material.

Assisted reproductive technology in the United States and Canada: 1994 results generated from the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry.

OBJECTIVE: To summarize the procedures and outcomes of assisted reproductive technology (ART) initiated in the United States in 1994. DESIGN: Data were collected on the Society for Assisted Reproductive Technology (SART) Database program and submitted to KMPG Peat Marwick, who served as the 1994 collection center for the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry. PARTICIPANT(S): Two hundred forty-nine programs submitted data on procedures performed in 1994. Data were collected after October 1995 so that outcome of all pregnancies established would be known. MAIN OUTCOME MEASURE(S): The outcomes measured included clinical pregnancy, ectopic pregnancy, abortion, stillbirth, delivery, and congenital abnormality. RESULT(S): Programs reported initiations of 39,390 cycles of ART treatment, excluding frozen embryo and donor oocyte cycles. Of these, 33,700 cycles initiated were IVF (standard, with micromanipulation, and for host uterus transfer) with 20.7% deliveries per retrieval; 4,214 were cycles of GIFT with 28.4% deliveries per retrieval; 926 were cycles of zygote intrafallopian transfer with 29.1% deliveries per retrieval; and 550 were combination cycles, combining IVF and one of the tubal transfer techniques, resulting in 29.7% deliveries per retrieval. In addition to these cycles initiated in 1994, 7,046 frozen ET procedures were reported, either as separate procedures or in combination with another ART procedure with 15.4% deliveries per procedure, and 3,119 donor oocyte cycles were initiated with an overall success of 46.8% deliveries per retrieval. As a result of all procedures, a total of 9,573 deliveries were reported. CONCLUSION(S): In 1994, there were fewer programs reporting a similar number of treatment cycles of ART as in 1993. Overall average success rates (deliveries per procedures) exhibited only a small increase compared with previously reported summaries.

Assisted reproductive technology in the United States and Canada: 1995 results generated from the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry.

OBJECTIVE: To summarize the procedures and outcomes of assisted reproductive technology (ART) initiated in the United States and Canada in 1995. DESIGN: Data were collected in the Society for Assisted Reproductive Technology database program and cycle reporting forms and were submitted to the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry. PARTICIPANT(S): Two hundred eighty-one programs submitted data on procedures performed in 1995. Data were collected after November 1996 so that outcome of all pregnancies established would be known. MAIN OUTCOME MEASURE(S): Procedural outcomes measured included clinical pregnancy, ectopic pregnancy, abortion, stillbirth, delivery, and congenital abnormality. RESULT(S): Programs reported initiating 59,142 cycles of ART treatment, including frozen embryo and donor oocyte cycles. Of these, 41,087 cycles initiated were IVF (with and without micromanipulation) with 22.5% deliveries per retrieval; 3,741 were cycles of gamete intrafallopian transfer with 27.0% deliveries per retrieval; 1,078 were cycles of zygote intrafallopian transfer with 27.9% deliveries per retrieval. In addition to these cycles initiated in 1995, 8,453 frozen embryo thaw procedures were reported, either as separate procedures or in combination with other ART procedures with 15.2% deliveries per transfer, 3,555 donor oocyte cycles were initiated with an overall success of 36.0% deliveries per transfer, 1,028 cryopreserved embryo thaw procedures from donated oocyte procedures with an overall success of 16.8% deliveries per transfer, and 200 ART treatment cycles in which a host uterus was used were initiated with an overall success of 34.9% deliveries per ET. As a result of all procedures, a total of 11,631 deliveries were reported, resulting in 16,520 neonates. CONCLUSION(S): In 1995, there were more programs reporting ART treatment and a significant (19.3%) increase in reported cycles. In comparable cycle types, overall average success rates (deliveries per transfer) exhibited a 0.6% increase or a 2.5% increase over the rates in the 1994 reported summaries.

Assisted reproductive technology in the United States: 1996 results generated from the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry.

OBJECTIVE: To summarize the procedures and outcomes of assisted reproductive technology (ART) initiated in the United States in 1996. DESIGN: Data were collected electronically using the Society for Assisted Reproductive Technology Clinical Outcome Reporting System software and submitted to the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry. PARTICIPANT(S): Three hundred programs submitted data on procedures performed in 1996. Data were collected after November 1997 so that the outcome of all pregnancies established would be known. MAIN OUTCOME MEASURE(S): Procedural outcomes measured included clinical pregnancy, ectopic pregnancy, abortion, stillbirth, delivery, and congenital abnormality. RESULT(S): Programs reported initiating 65,863 cycles of ART treatment, including frozen embryo and donor oocyte cycles. Of these. 44,647 cycles initiated were in vitro fertilization (IVF) (with and without micromanipulation) with 26.0% deliveries per retrieval; 2,879 were cycles of gamete intrafallopian transfer (GIFT) with 29.0% deliveries per retrieval; 1,200 were cycles of zygote intrafallopian transfer (ZIFT) with 30.9% deliveries per retrieval. In addition to these cycles initiated in 1996, 9,610 frozen embryo transfer procedures were initiated with 16.8% deliveries per transfer, 3,768 donor oocyte cycles were initiated with an overall success of 39.1% deliveries per transfer, 1,096 cryopreserved embryo transfers from donated oocytes procedures with an overall success of 20.8% deliveries per transfer, and 688 ART treatment cycles using a host uterus were initiated with an overall success of 31.3% deliveries per embryo transfer. Also, 1,341 cycles were reported as combinations of more than one treatment type, 19 cycles as research, 311 as embryo banking, and 304 as other (unclassified) cycle types. As a result of all procedures, a total of 14,702 deliveries were reported resulting in 21,196 neonates. CONCLUSION(S): In 1996, there were more programs reporting ART treatment and a significant (11.3%) increase in reported cycles. In comparable cycle types, overall average success rates (deliveries per retrieval) exhibited an actual increase of 3.5% (this is an increase of 15.8% when compared to the success rate for 1995).

NASA/DARPA advanced communications technology satellite project for evaluation of telemedicine outreach using next-generation communications satellite technology: Mayo Foundation participation.

OBJECTIVE: To describe the development of telemedicine capabilities-application of remote consultation and diagnostic techniques-and to evaluate the feasibility and practicality of such clinical outreach to rural and underserved communities with limited telecommunications infrastructures. MATERIAL AND METHODS: In 1992, Mayo Foundation (Rochester, Minn, Jacksonville, Fla, and Scottsdale, Ariz), the National Aeronautics and Space Administration, and the Defense Advanced Research Projects Agency collaborated to create a complex network of fiberoptic landlines, video recording systems, satellite terminals, and specially developed data translators linking Mayo sites with other locations in the continental United States on an on-demand basis. The purpose was to transmit data via the asynchronous transfer mode (ATM) digital communications protocol over the Advanced Communications Technology Satellite. The links were intended to provide a conduit for transmission of data for patient-specific consultations between physicians, evaluation of medical imagery, and medical education for clinical staffs at remote sites. RESULTS: Low-data-rate (LDR) experiments went live late in 1993. Mayo Clinic Rochester successfully provided medical consultation and services to 2 small regional medical facilities. High-data-rate (HDR) experiments included studies of remote digital echocardiography, store-and-forward telemedicine, cardiac catheterization, and teleconsultation for congenital heart disease. These studies combined landline data transmission with use of the satellite. The complexity of the routing paths and network components, immaturity of available software, and inexperience with existing telecommunications caused significant study delays. CONCLUSIONS: These experiments demonstrated that next-generation satellite technology can provide batch and real-time imagery for telemedicine. The first-generation of the ATM and satellite network technology used in these experiments created several technical problems and inconveniences that should be overcome as the network infrastructure matures.

The preliminary economic evaluation of health technologies for the prioritization of health technology assessments. A discussion.

This paper critically evaluates methods for the preliminary economic evaluation of health technologies and the prioritization of health technology assessment projects. It reports on the literature, and considers methods currently employed and the purposes of preliminary appraisal. It concludes that a preliminary economic appraisal needs to be applied to the two main stages of the prioritization process; to have transparent criteria; to allow for an appropriate range of potential outcomes; to be practicable, flexible, and efficient; and to be relevant to the assessment of different research projects.
