Complementary analyses in economic evaluation of health care

The steady increase in health care costs and the continuous emergence of new medical technologies have forced policy makers in health care to reconsider the current resource allocation and to become more selective with investing in new health care programs. Economic evaluations can support the decision making process, by providing systematic information on the costs and the consequences for health of investing in alternative health care programs. Needless to say, economic evaluations of health care should be methodologically sound, the outcomes should be relevant for health policy and comparable to results of studies concerning other health care programs. With respect to the policy relevance it is important that the aggregation level of the analysis matches the specificity of the policy question: a study of costs and health effects of for example air pollution control will not need to be as detailed as an analysis of the cost-effectiveness of cimetidine versus surgery in peptic ulcer. Economic evaluations may never become entirely comparable, but incomparabilities due to different methodologies can be reduced considerably. This raises two questions: - what is the appropriate level of aggregation in the economic evaluation of health care? - which cost items are to be included in economic evaluations and how should these be measured and valued, in particular the indirect costs of disease

Towards a new approach for estimating indirect costs of disease

__Abstract__ Many researchers in the field of evaluation of health care doubt the usefulness of estimates of indirect costs of disease in setting priorities in health care. This paper attempts to meet part of the criticism on the concept of indirect costs, which are defined as the value of production lost to society due to disease. Thus far in cost of illness studies and cost-effectiveness analyses the potential indirect costs of disease were calculated. In the following a first step will be taken towards a new method for estimating indirect costs which are expected to be effectuated in reality: the friction cost method. This method explicitly takes into account short and long run processes in the economy which reduce the production losses substantially as compared with the potential losses. According to this method production losses will be confined to the period needed to replace a sick worker: the so called friction period. The length of this period and the resulting indirect costs depend on the situation on the labour market. Some preliminary results are presented for the indirect costs of the incidence of cardiovascular disease in the Netherlands for 1988, both for the friction costs and the potential costs. The proposed methodology for estimating indirect costs is promising, but needs further development. The consequences of illness in people without a paid job need to be incorporated in the analysis. Also the relation between internal labour reserves and costs of disease should be further investigated. Next to this, more refined labour market assumptions, allowing for diverging situations on different segments of the labour market are necessary

The management of cervical intra-epithelial neoplasia (CIN): Extensiveness and costs in The Netherlands

In order to provide greater insight into both the extensiveness and the medical costs of the diagnosis and treatment of screen-detected cervical intra-epithelial neoplasia (CIN) in general medical practice in The Netherlands, data from national registries and gynaecology departments were retrieved, and experts were interviewed. Of the 5060 women diagnosed with CIN in 1988, more than 50% were treated in hospital with conisation or hysterectomy, which on average took 5.5 days stay per admission. The assessed average duration of the total pre- and post-treatment period is 4.6 years. The average total medical costs in women with detected CIN III are Dfl 3700 per woman. The diagnosis of CIN I and II involves more medical procedures and time than CIN III, but fewer women have conisation or hysterectomy, resulting in lower total medical costs (Dfl 2572). The overall extent and costs of the management of CIN should be accounted for when balancing the benefits, unfavourable effects and costs of cervical cancer screening

Costs of home care for advanced breast and cervical cancer in relation to cost-effectiveness of screening

__Abstract__ The costs of home care in the Netherlands are estimated for women with advanced breast and cervical cancer. We observe a growing role of intensive home care for the terminally ill patients. The average costs of home care are dfl 8500 per patient for breast cancer patients and dfl 7200 for cervical cancer patients. More than half of these costs are incurred in the last month before death. The level of home care in the preceding months is quite modest (dfl 120 per month for both diseases), not taking into account informal care. The costs of home care for patients with advanced cancer are only slightly related to the site of the primary tumor from which the metastases originate. Total average costs per patient during advanced disease, including hospital and nursing home care, amount to dfl 42,700 for breast cancer and dfl 29,000 for cervical cancer. This difference in costs is largely attributable to the longer duration of advanced disease for breast cancer, which substantially affects hospitalcosts. The high costs of care to patients with advanced cancer contribute to a favourable cost-effectiveness ration of those screening programmes which reduce mortality and consequently the costs of care to advanced cancer patients

A cost-effectiveness study of ICT training among the visually impaired in the Netherlands

Background: Due to the ageing population, the number of visually impaired people in the Netherlands will increase. To ensure the future availability of services in rehabilitative eye care, we aim to assess the cost-effectiveness of information and communication technology (ICT) training among visually impaired adults from a societal perspective, using primary data from two large rehabilitative eye care providers in the Netherlands. Methods: Participants were asked to fill in a questionnaire, which used six different instruments at three different time points: pre training, post training and three months post training. We investigated whether the participants' quality of life and well-being improved after the training and whether this improvement persisted three months post training. Economic evaluation was conducted by comparing costs and outcomes before and after training. Quality of life and well-being were derived from the EQ-5D and ICECAP-O, respectively. Costs for productivity losses and medical consumption were obtained from the questionnaires. Information regarding the costs of training sessions was provided by the providers. Results: Thirty-eight participants filled in all three questionnaires. The mean age at baseline was 63 years (SD = 16). The effect of ICT training on ICT skills and participants' well-being was positive and persisted three months after the last training session. Assuming these effects remain constant for 10 years, this would result in an incremental cost-effectiveness ratio (ICER) of € 11,000 per quality-adjusted life-year (QALY) and € 8000 per year of well-being gained, when only the costs of ICT training are considered. When the total costs of medical consumption are included, the ICER increases to € 17,000 per QALY gained and € 12,000 per year of well-being gained. Furthermore, when the willingness-to-pay threshold is € 20,000 per year of well-being, the probability that ICT training will be cost-effective is 75% (91% when including only the costs of ICT training). Conclusion: Our study suggests that ICT training among the visually impaired is cost-effective when the effects of ICT training on well-being persist for several years. However, further research involving a larger sample and incorporating long-term effects should be conducted

Handbook of Health Economics

Editors and authors should be complimented for their impressive attempt to provide a fair account of the state-of-the-art in health economics. To review such an extensive work in a short time span, we decided to select certain chapters for more in depth study. This selection was based on our areas of expertise under the restriction that all major research areas distinguished in the handbook should be covered. Before turning to the review of the separate chapters, let us first make some general comments about the handbook. An important first question is whether all relevant research areas are covered and whether this has been done in a balanced way. Of course, exhaustive coverage in one book is unattainable for a large area like health economics. Rather the question is that regarding balance and possible lack of bias. In that respect, the book focuses on the US literature and health care system with 24 chapters written by US authors and only 11 by European and Canadian authors. The more traditional economic areas are generally covered by the US authors, emphasising a neo-classical rather than an institutional paradigm, and boundary topics like ‘equity’ and the ‘measurement of health’ are covered by the non-US authors. This structure both reflects the contributions in the health economics literature and the large variation in US health care institutions, and is on

Health Expenditure Growth: Looking beyond the Average through Decomposition of the Full Distribution

Explanations of growth in health expenditures have restricted attention to the mean. We explain change throughout the distribution of expenditures, providing insight into how growth and its explanation differ along the distribution. We analyse Dutch data on actual health expenditures linked to hospital discharge and mortality registers. Full distribution decomposition delivers findings that would be overlooked by examination of changes in the mean alone. The growth in expenditures on hospital care is strongest at the middle of the distribution and is driven mainly by changes in the distributions of determinants. Pharmaceutical expenditures increase most at the top of the distribution and are mainly attributable to structural changes, including technological progress, making treatment of the highest cost cases even more expensive. Changes in hospital practice styles make the largest contribution of all determinants to increased spending not only on hospital care but also on pharmaceuticals, suggesting important spill over effects

Implementation of clinical guidelines on physical therapy for patients with low back pain: randomized trial comparing patient outcomes after a standard and active implementation strategy

Contains fulltext : 47628.pdf (publisher's version ) (Closed access)BACKGROUND AND PURPOSE: An active strategy was developed for the implementation of the clinical guidelines on physical therapy for patients with low back pain. The effect of this strategy on patients' physical functioning, coping strategy, and beliefs regarding their low back pain was studied. SUBJECTS: One hundred thirteen primary care physical therapists treated a total of 500 patients. METHODS: The physical therapists were randomly assigned to 1 of 2 groups. The control group received the guidelines by mail (standard passive method of dissemination). The intervention group, in contrast, received an additional active training strategy consisting of 2 sessions with education, group discussion, role playing, feedback, and reminders. Patients with low back pain, treated by the participating therapists, completed questionnaires on physical functioning, pain, sick leave, coping, and beliefs. RESULTS: Physical functioning and pain in the 2 groups improved substantially in the first 12 weeks. Multilevel longitudinal analysis showed no differences between the 2 groups on any outcome measure during follow-up. DISCUSSION AND CONCLUSION: The authors found no additional benefit to applying an active strategy to implement the physical therapy guidelines for patients with low back pain. Active implementation strategies are not recommended if patient outcomes are to be improved

Indirect costs of disease; an international comparison

Results of economic evaluations are often strongly influenced by estimates of indirect costs. International comparability of these estimates may contribute to rational decision-making in health care policy. Hence, estimates should be international comparable. Comparability of these results between countries may be hampered due to variation in methodology, data sources, valuation of production losses, and social security arrangements. Furthermore differences in epidemiology, demography and economic environment may cause variation in the level and the distribution by diagnosis of indirect costs. In this study indirect costs of disease for the Netherlands are compared with estimates for Sweden and the United States. We found large differences: both in the share of indirect costs in GDP as in the constituting elements, absence from work, disability and mortality. The level of indirect costs due to absence from work and the distribution according to diagnosis are quite similar for the two European countries. The costs of disability are particularly high for the Netherlands. Comparison of disability costs between the three countries is hampered due to lack of quantitative information on the influence of social insurance arrangements on the level of indirect costs and the distribution by diagnosis. The large number of deaths at young age in the U.S. is responsible for the higher mortality costs compared to the two European countries
