Health technology assessment in Australia: a need to re-focus.

Health technology assessment in Australia has been undertaken for a number of years. While there have been many useful achievements, problems remain with the coverage and timeliness of assessments and with access to information on healthcare technologies. Further desirable developments might include greater involvement of State agencies, professional bodies and industry, and the identification of a single focus for provision of information.

The Alberta Ambassador Program: delivering Health Technology Assessment results to rural practitioners.

BACKGROUND: The purpose of Health Technology Assessment (HTA) is to make the best possible summary of the evidence regarding specific health interventions in order to influence health care and policy decisions. The need for decision makers to find relevant HTA data when it is needed is a barrier to its usefulness. These barriers are highest in rural areas and amongst isolated practitioners. METHODS: A multidisciplinary team developed an interactive case-based instructional strategy on the topic of chronic non-cancer pain (CNCP) management using clinical evidence derived by HTA. The evidence for each of 18 CNCP interventions was distilled into single-sheet summaries. Clinicians and HTA specialists ('Ambassadors') conducted 11 two-hour interactive sessions on CNCP in eight of Alberta's nine health regions. Pre- and post-session evaluations were conducted. RESULTS: The sessions were attended by 130 individuals representing 14 health and administrative disciplines. The ambassador model was well received. The use of content experts as ambassadors was highly rated. The educational strategy was judged to be effective. Awareness of the best evidence in CNCP management was increased. Although some participants reported practice changes as a result of the workshops, the program was not designed to measure changes in patient outcome. CONCLUSION: The ambassador program was successful in increasing awareness of the best evidence in CNCP management, and positively influenced treatment decisions. Its teaching methods were felt to be unique and innovative by participants. Its methods could be applied to other clinical content areas in order to increase the uptake of the results of HTA.

Defining the future of health technology: biomechatronics.

Future progress in healthcare and medicine depends on today's investment in research, development, and education. We cannot leave such urgent issues to determine themselves, but rather must actively collaborate to ensure a stable healthcare system. This chapter describes efforts made by leading experts in industry, government, and academia to better ascertain future healthcare management. Such collaboration has occurred during a series of Future Healthcare Technology Summits helping in planning investments in health technology. Deliberating and reviewing plans before taking action will accelerate progress as it will (1) save costs, (2) encourage compliance, (3) improve clinical outcomes, and (4) ensure greater patient satisfaction. What we must resolve is: How can we invest a couple billion dollars to save hundreds of billions and, most importantly, increase human health in the future. A new branch of science, Biomechatronics, with millions of Intelligent Caring Creatures- is the answer.

The European way to health technology assessment. Lessons from an evaluation of EUR-ASSESS.

OBJECTIVES: The EUR-ASSESS project was undertaken by a large number of members of European health technology assessment (HTA) agencies and programs with the aim of improving coordination through developments in several areas of HTA. At the conclusion of the project, an independent survey was undertaken to reassess the importance of the original objectives of EUR-ASSESS and determine the impact of the project on the way HTA activities are organized and carried out in Europe. METHODS: A postal questionnaire survey and a series of more in-depth personal interviews. RESULTS: EUR-ASSESS was generally considered successful in achieving its aims, particularly in creating an informal network of people and organizations, improving the understanding of the work of others, improving the ability to focus the objectives of HTA, facilitating the sharing of experience and mutual learning opportunities, exchanging ideas on research agendas, and developing a common language. However, significant differences emerged in the expectations of different actors in European HTA, and in their perceptions of the impact of the project. These reflect the wide diversity of approaches existing in Europe. CONCLUSIONS: Health technology assessment in Europe is changing its nature from a set of national or local initiatives with relatively limited impact to a truly European movement with strong links and coordination between its individual components. Important lessons can be learned from the experience of EUR-ASSESS, particularly in the light of an increasing commitment of the European Commission to play a role in the development of technology assessment.

An iterative Bayesian approach to health technology assessment: application to a policy of preoperative optimization for patients undergoing major elective surgery.

PURPOSE: This article presents an iterative framework for managing the dynamic process of health technology assessment. The framework uses Bayesian statistical decision theory and value of information (VOI) analysis to inform decision making regarding appropriate patient management and to direct future research effort over the lifetime of a technology. Within the article, the framework is applied to a policy decision regarding preoperative patient management before major elective surgery, for which trial data are available. METHOD: The evidence available prior to the trial is used to determine the appropriate method of patient management and to ascertain whether, at the time of commissioning, the trial was potentially worthwhile. The prior information is then updated with the trial data via a Bayesian analysis using informative priors. This post trial information set is then used to reassess the appropriate method for patient management and to determine whether there is a requirement for any further research. RESULTS: Prior to the trial, preoperative optimization with dopexamine is identified as the appropriate method of patient management. The results of the VOI analysis suggest that a short-term trial was potentially worthwhile (population expected value of perfect information [EVPI] = 48 million pounds sterling). Following the trial, the uncertainty surrounding the choice of appropriate patient management and the potential worth of further research had increased (population EVPI = 67 million pounds sterling). CONCLUSIONS: The article demonstrates the value and practicality of applying the iterative framework to the dynamic process of health technology assessment. It is only by formally incorporating all of the information available to decision makers, through informed priors, that the appropriate decisions can be made.

Reflections on the social epidemiologic dimension of health technology assessment.

Certain key parameters such as safety, efficacy, effectiveness, and cost effectiveness have long been established as key in HTA analysis. Equally important, however, are sociolegal and epidemiologic perspectives. A comprehensive analytic framework will consider the implications of using a technology in the context of societal norms, cultural values, and social institutions and relations. The methodology in which this expanded framework has been developed is termed 'Strategic HTA' to denote its power for the decision-making process. In addition to systematic reviews of published evidence, it incorporates analyses of the influence of dominant social relations on technological development and diffusion. This essay discusses the social epidemiologic aspects of health technology assessment, which includes factors such as sex and gender. It seeks to show how it is possible to bring data from wide-ranging disciplinary perspectives within the parameters of a single scientific inquiry; to draw from them scientifically defensible conclusions; and thereby to realize a deeper understanding of technology impact within a health care system. Armed with such an understanding, policy officials will be better prepared to resolve the competitive clamor of stakeholder voices, and to make the most "equitable" use of the available resources.

Managing partnerships and impact on decision-making: the example of health technology assessment in genetics.

For an emerging field such as Public Health Genetics, the partnerships that will be developed with stakeholders are of strategic importance, since they may affect long-term impact on policy-making. A concrete example in the field of health technology assessment in genetics was chosen to illustrate how the context in which scientific advisory bodies operate and the nature of partnerships developed over time influence the impact on decision-making at different levels, from the micro (professional) level through the meso (institutional) level to the macro (policy) level. As pointed out in the knowledge transfer literature, impact is not only reflected by instrumental use of knowledge, but also by problem-framing and strategic use of knowledge. Solid partnerships at the micro level, with researchers and health care professionals, are essential to build credibility and trust, and they lay the groundwork for contextualized and relevant advice and potential impact at the policy level. Even though maintaining the necessary critical distance with respect to all stakeholders is easier for institutions that are at arm's length from government, achieving the right balance between an institution's independence and service relationship is a real challenge.

Validity of original studies in health technology assessment reports: significance of standardized assessment and reporting.

OBJECTIVES: As health technology assessments (HTA) may have considerable impact on health-care decisions, it is essential to guarantee the expected quality of these assessments. Variations in the methods used or lack of transparency can affect the important role of HTA reports. METHODS: In our study, we analyzed the methods used in two corresponding HTA reports to assess the validity of two key papers, which were included in both reports. Also the discussions and the final conclusions of both reports were compared. RESULTS: The authors of the two HTA reports used different instruments to assess the validity of the original studies. A minor problem is differences that were found in the assessments of identical validity aspects of the included studies and in the information provided in the HTA reports. A more serious problem was found in both HTA reports which identified the weakness of the key papers and expressed these limitations in the discussions (read mainly by scientists) but not in the conclusions (read mainly by policy-makers). CONCLUSIONS: The results of this study may be important for any institution that prepares recommendations for policy-makers. In the case of HTA reports, no new checklists are necessary as the checklist offered by the INAHTA contains the needed information. It may be necessary, however, to consider an "intramural quality board," which helps the member organizations guarantee both the transparency of the original studies included in HTA reports and the transparency of the HTA report itself.

Predicting the impact of new health technologies on average length of stay: development of a prediction framework.

OBJECTIVES: The aim of this study was to develop a framework to predict the impact of new health technologies on average length of hospital stay. METHODS: A literature search of EMBASE, MEDLINE, Web of Science, and the Health Management Information Consortium databases was conducted to identify papers that discuss the impact of new technology on length of stay or report the impact with a proposed mechanism of impact of specific technologies on length of stay. The mechanisms of impact were categorized into those relating to patients, the technology, or the organization of health care and clinical practice. RESULTS: New health technologies have a variable impact on length of stay. Technologies that lead to an increase in the proportion of sicker patients or increase the average age of patients remaining in the hospital lead to an increase in individual and average length of stay. Technologies that do not affect or improve the inpatient case mix, or reduce adverse effects and complications, or speed up the diagnostic or treatment process should lead to a reduction in individual length of stay and, if applied to all patients with the condition, will reduce average length of stay. CONCLUSIONS: The prediction framework we have developed will ensure that the characteristics of a new technology that may influence length of stay can be consistently taken into consideration by assessment agencies. It is recognized that the influence of technology on length of stay will change as a technology diffuses and that length of stay is highly sensitive to changes in admission policies and organization of care.

Health policy, health technology assessment, and screening in Europe.

OBJECTIVE: To present a summary of the papers in this volume, illustrating the links between health technology assessment (HTA), health policies and specifically policies toward prevention and screening, and implementation of screening tests in the case of three screening methods: mammography screening for breast cancer, screening for prostate cancer, and routine use of ultrasound in pregnancy. METHOD: To commission papers from eight European countries based on a set of questions to be answered, as well as a paper synthesizing the scientific literature on the three screening procedures. RESULTS: Indicate that few of the countries examined have developed effective links between HTA, health policy, and implementation related to screening procedures. Only Sweden and the Netherlands appear to have developed such links. In the other countries, HTA has a limited role in determining health policy. It also seems to be uncommon for countries to have a specific prevention strategy. CONCLUSION: The major conclusion is that countries of Europe need to develop HTA as part of prevention policies.

Health technology assessment: the contribution of qualitative research.

The pragmatism in health care has made health technology assessment (HTA) restrict its scope to a particular set of problems, c.q. methods. The "multidisciplinary and comprehensive nature" of HTA, as the concept is presented in certain definitions, is lacking. Health care is also dominated by a positivistic-rationalistic approach of evaluation. In contrast, social studies of evaluations learn that a major difference has to be made between scientific research on (potential) impact of a technology and valuing these effects. In this contribution, we will discuss how the positivistic scientific bias of current HTA practice can be made up with other research traditions. More specifically, we focus on the question of how social scientists and particularly how qualitative research can contribute to HTA, complementary to positivistic studies of evidence and efficacy.

Australian economic evaluation and government decisions on pharmaceuticals, compared to assessment of other health technologies.

In this paper the first theme is the experience with the routine use of cost-effectiveness analysis in decisions by the Australian Pharmaceutical Benefits Advisory Committee on whether drug products should attract a government subsidy. As a second theme, the contrasting experience with several other health technologies is presented, with economic analysis being less frequently used in a system where there is a weaker regulatory framework. Some general points that emerge in both areas are the importance of factors other than economic evaluation in the decision-making process, and the need to make policy and administrative decisions on the basis of limited data. There is limited material available in the public domain on the interaction of economic evaluation and Australian policy on health technologies. It has been necessary, particularly in relation to the case studies presented here, to rely on input from discussion with a number of individuals and on observations made during personal involvement with some of the assessments. It is not possible to offer substantive evidence in support of this material, and indeed firm evidence in the area of impact of assessments on health policy remains difficult to collect.

Striving for evidence in e-health evaluation: lessons from health technology assessment.

Evaluation is crucial to the integration of e-health applications into the health-care system and their ultimate sustainability. However, e-health evaluation is often criticized for the poor quality of research design, the lack of common outcome indicators and the absence of an agreed theory. Health technology assessment (HTA) could offer a sound methodological basis for e-health evaluation. However, there have been major concerns about the applicability of the HTA approach to the evaluation of e-health initiatives. Evaluators -- and decision makers -- must accept that telehealth evaluation may serve different purposes for different stakeholders, and therefore concede that no single evaluation framework or methodology, even the randomized controlled trial, is totally objective. To address the complex environment of telehealth evaluation, a participatory strategy is useful, whereby stakeholders are involved in the study design and definition of evaluation questions at each phase. This will also build confidence between the evaluation team and the stakeholders, facilitating informed decision making through an integrated knowledge mobilization activity.

Positron emission tomography: establishing priorities for health technology assessment.

BACKGROUND: Positron emission tomography (PET) is an expensive diagnostic imaging technology. Despite the long history of PET development, the costs and effectiveness of its use in routine clinical practice remain unknown. Against this background of uncertainty regarding the clinical role of PET, the UK Standing Group on Health Technology requested a review of its current and potential role which would enable research priorities in this area to be established. OBJECTIVES: This 3-month project had two explicit objectives: (1) to review the state of knowledge regarding the clinical applications of PET; (2) to determine the key health technology assessment (HTA) research questions relating to the use of PET in the UK. METHODS: A literature review to ascertain the state of knowledge regarding the clinical applications of PET and a three-round Delphi study to inform the key HTA research questions relating to the use of PET in the UK were undertaken. The results of an earlier systematic review, published by the Veteran's Health Administration (VHA) in the USA in 1996, were used as the starting point for the literature review. The VHA review was updated and extended by means of MEDLINE and Cochrane Library database searches. Participants in the Delphi study were selected by discussion with five individuals in the UK with an interest in, and awareness of, developments in PET. As a result of their suggestions, 43 individuals were initially invited to participate, of whom two did not feel appropriately qualified. Questionnaires were sent by facsimile to all invited participants, who were asked to return the completed forms by facsimile within a week. The content and structure of the Delphi study was informed by the results of the literature review. The responses and comments of the participants were a major source of information for this report. RESULTS: Clinical applications for PET have been advocated in three broad disease groups: oncology, cardiology and neuropsychiatric disorders. There are currently four PET modalities that need to be considered when assessing its potential clinical role in the UK: full ring PET scanners operating in two or three dimensions (available at five sites); partial ring rotating PET scanners (one currently operating in the UK); coincidence imaging with modified gamma camera technology; and high-energy collimator imaging of 511 keV photons with modified gamma camera technology. There is a paucity of available evidence relating to the cost-effectiveness of the various PET modalities in all of the clinical indications for which the technology is currently being advocated. In addition, many existing reports on the diagnostic accuracy of PET are limited because they are liable to bias and often relate only to very small patient numbers. The results of the Delphi study indicated that the four most important research priorities for the NHS, in descending order of their importance, are: (1) the relative cost-effectiveness of (a) full ring PET, (b) gamma camera PET using coincidence imaging and (c) existing diagnostic strategies to determine staging prior to operative intervention for lung cancer; (2) partial ring PET compared with full ring PET in oncology (3) the relative cost-effectiveness of (a) full ring PET, (b) gamma camera PET using coincidence imaging and (c) existing diagnostic strategies to stage and monitor treatment response in breast cancer; (4) the relative cost-effectiveness of (a) gamma camera PET using coincidence imaging and (b) 511 keV collimated positron imaging for assessing myocardial viability when selecting patients for revascularisation surgery. Vignettes describing each of the research priorities are provided in the main report. CONCLUSIONS: The findings of this project, which was undertaken rapidly in order to inform HTA research prioritization in the UK, provide a contemporary overview of the potential clinical role for PET in the NHS. Evidence is needed that using PET as a diagnostic

Health technology assessment in the area of prevention: selected screening cases in Greece.

OBJECTIVE: To explore the impact of health technology assessment (HTA) on health policy and practice in Greece through selected screening case studies in the prevention area. The three cases studied were mammography screening, PSA screening, and routine ultrasonography in normal pregnancy. METHODS: Official policy recommendations or reports, a literature review of Greek published research as well as gray literature from various sources, and interviews with specialists and medical associations were performed, and their impact on health policy formulation was examined. RESULTS: The implementation of the screening tests does not take the form of structured mass screening programs. Almost all physicians (urologists-pathologists, gynecologists) apply PSA and routine ultrasonography in normal pregnancy respectively with the purpose of either prevention or diagnosis. Mammography is applied generally for prevention or diagnosis, but there are some mass screening programs at a local level. In addition, the results show no evidence that the efficacy and the cost-effectiveness of the three screening programs have been a matter of serious concern and investigation for the purposes of policy formulation in Greece. CONCLUSION: The results point to a need for the implementation of HTA methods on mass screening preventive programs in which real value and cost remain unclear and whose use is based on empirical and personal assessments.

Application of strengths, weaknesses, opportunities and threats analysis in the development of a health technology assessment program.

There has been recent interest in developing a health technology assessment (HTA) function in Estonia. A group of individuals knowledgeable about HTA in Canada, Germany, Romania and Spain, along with representatives of the University of Tartu, Estonia, was convened by the Institute of Health Economics in Edmonton, Canada, to consider options for such a function. In a one-day workshop strengths, weaknesses, opportunities and threats (SWOT) analyses of HTA were conducted, first at a 'global' level, and then of the Estonian situation. The 'global' SWOT analysis yielded a large number of items that pertain to institutionalized HTA in a generic sense, i.e. not based on any individual HTA agency. The 'Estonian' SWOT yielded a subset of items, which pertain to development of HTA in that country. Ten actionable steps were then developed on the basis of this subset, which could be used to initiate the creation of an HTA body in Estonia.
