An overview of published studies on three common cancers in childhood was conducted to estimate the effectiveness and consequences of treatment. Of 1,016 separate citations, 316 were reviewed in detail but only 162 were deemed to be “useful.” An approach to a structured appraisal of the literature is presented.

In assessing technologies for disabled people, the aims of habilitative or rehabilitative interventions, the concepts of disability and handicap, and the potential of existing and emerging technologies in various social arenas, as well as the structure of service delivery systems, are of importance. A discussion of these issues in the light of previous work on cost and effectiveness in the field is given.

There is an informational void about Pharmaceuticals in the training of most doctors, despite the importance of the prescription in medical care. The writing of the prescription is the final common pathway in therapeutic decision making, which involves such diverse forces and disciplines as anthropology, decision science, health economics, ethics, and politics, as well as pharmacology and clinical medicine. Programs to improve the precision and cost-effectiveness of doctors' prescribing must consider all of these factors if pharmacotherapeutics are to be used optimally.

Analysis of the septic work-up of 194 neonates at Women's College Hospital, Toronto, showed that the only antepartum condition predicting neonatal sepsis was the mother being on antibiotics. The only postnatal condition predicting sepsis was a maternal postpartum white blood cell count over 11,000. The average cost for tests for a septic work-up in these 194 mother-neonate pairs was $71.48 (Canadian dollars), and the average cost of tests to find a septic case was $1,066.77.

Recent health reports, including the 1993 World Development Report, have emphasized the importance of integrating the needs of the population into technology assessment. This paper reviews previous approaches to technology assessment and identifies the missing link between technology and its impact on the physical, emotional, and social needs of the community, namely needs-based technology assessment. It stresses the key role played by issues of equity and community values in making technology decisions. A number of models for needs-based technology assessment are described.

The main task of this paper is to contribute to the theory of disabilities and handicaps, in particular their characterization and classification. It presents an analysis of the conditions for the successful performance of actions. By this procedure a list of reasons for failure of action, i.e., for disability and handicap, is obtained. This list can be used for a detailed classification of disabilities and handicaps. Some theories in modern philosophical action theory serve as platforms for the analysis.

The elemental resource model (ERM) attempts to provide a quantitative and straightforward framework for characterizing the human system, tasks, and their interface. It evolved in large part from the general systems performance theory (GSPT), which was developed first and independently. Resource constructs are used exclusively for modeling the abstract idea of system performance and for subsequent measurement of performance resource capacities. Resource economic principles provide a cause-and-effect description of the human-task interface. While argued to have immediate utility, it also provides the motivation to consider coordinated, collaborative, long-term developments that could facilitate effective decision making and technology utilization in rehabilitation.

We examined a screening program for colorectal cancer in South Australia in terms of its overall direct costs to society and costs to participants. The best estimate of the cost per cancer detected was $18,924 (Australian dollars). Potential improvements in health outcome through screening are discussed in light of these costs.

Investment in health can offer additional benefits to development independent of economic improvement. Many technologies have been useful in improving the health of the people in the past. However, rapid and often unpredictable change has contributed to the inequity, inefficiency, and rising cost of health care. This paper outlines why a needs-based approach to assessing any new technology in the health sector is essential. To respond to changing needs, capacities within the health care system, several of which are described here, must be strengthened. Needs-based technology planning and implementation is affordable and feasible and is crucial in order that both health as a basic human right and good health at low cost can be attained.

A short description is given of the interplay between the pharmaceutical industry and its critics regarding the rational use of medicines since the 1960s. This was especially vigorous in the developing countries but also had ramifications in the industrialized world. The initiatives taken by the World Health Organization in starting a dialogue between the industry representatives in the International Federation of Pharmaceutical Manufacturers Associations and the critical voices of Health Action International are specially emphasized. The recent developments in the therapy of primary hypertension and peptic ulcer are discussed briefly as examples of the rapid changes in what should be rational in pharmacologic treatment of disease.

This paper investigates the theoretical properties of healthy-years equivalents (HYEs) and quality-adjusted life-years (QALYs). A distinction is made between ex ante HYEs (EA-HYEs) and expected HYEs (EXP-HYEs) and between risk-neutral quality-adjusted life-years (RN-QALYs) and risk-adjusted quality adjusted life-years (RA-QALYs). In the case of certainty, HYEs always rank health profiles according to individual preferences, whereas QALYs only rank health profiles according to individual preferences if constant proportional trade-off holds for all health states and if additive independence of quality in different periods holds. In the case of uncertainty, EA-HYEs always rank risky health profiles the same way as expected utility. The assumptions needed for the other measures to rank risky health profiles the same way as expected utility are: risk neutrality with respect to healthy time for EXP-HYEs; risk neutrality with respect to time in all health states and additive independence of quality in different periods for RN-HYEs; and constant proportional risk posture with respect to time in all health states and additive independence of quality in different periods for RA-QALYs.

The delivery of rehabilitation services requires an infrastructure if service provision is to be given any priority. This article discusses some characteristics of handicaps, technical aids, the service delivery process, and habilitation/rehabilitation, and recommends developments of national structures for service delivery based upon the characteristics of rehabilitation technology, user need, and the country frameworks.

Countries worldwide spend huge sums on health—about $1,700 billion a year, or roughly 8% of global income. But the World Development Report 1993: Investing in Health shows that these monies could be spent much more wisely, in the process doing a great deal to help the world's 1 billion poor. Essential national public health and clinical packages are proposed based on assessment of the burden of disease (measured in disability adjusted life years) and the cost-effectiveness of interventions. Governments can play a central role in improving the health of their citizens: they can foster an environment that enables households to improve health and they can also improve their own spending on health, targeting it to support universal access to essential national public health and clinical packages based on the above methods. This is a good example of the concept of needs-based technology assessment, combining the disciplines of epidemiology, economics, and policy formulation. When applied, it should lead to improved effectiveness, efficiency, and equity.

This paper describes the evolution of written patient information on prescription drugs, FDA's patient package insert proposal and its revocation before its implementation in the early 1980s, the status of voluntary and government efforts since that time, and a review of current trends in this area. The burgeoning practice of direct-to-consumer advertising of prescription drugs in the lay press is viewed within the context of these efforts. This paper also reviews the current developments in certain FDA regulated consumer products—over-the-counter drug labeling and nutrition labeling. The current state of patient information in the United States is reviewed in light of programs to improve prescription drug counseling, and current research in this area is discussed.

This article describes the experience at the Greater Victoria Hospital Society of assessing the appropriateness of introducing laparoscopic cholecystectomy (lap chole) within the framework of an established technology assessment process. Lap chole promised to deliver cost savings; however, these could only be realized by capitalizing on the reduced length of stay by removing the surgical beds from service. A cautionary note is raised as to whether the increased use of lap chole in the population is appropriate.

Technical innovations have enormous potential for enhancing the lives of people with disabilities, often providing means for substantial independence and contributing to their dignity. This paper uses a framework related to the personal needs of individuals throughout the hours of waking and rest. Examples of various potentialities are provided and discussed.

This article describes a project that looked at the availability of information on marketed pharmaceutical products to doctors and patients in six European countries. It examines the legal status of the drug compendia published in each country and reports on the Implementation of EC Directive 92/27/EEC on labeling and packaging. A small survey showed that it is hard to compare patient information because it is difficult to obtain copies of pack inserts available in each country. However, a limited analysis revealed some differences in the content and presentation of data for doctors and patients.

A cost-utility analysis (CUA) was applied to group living for dementia patients. A Markov-model of an expected life-length of 8 years was used. Forty-six patients in group living were compared to 39 patients living at home by inclusion and 23 institutionalized patients. When the cost per gained quality-adjusted life-year (QALY) was calculated, the group living alternative was the most favorable for the patients, giving a cost per paired QALY of US dollars > 0. In the extensive sensitivity analysis the main result was consistent but methodological problems were indicated.
