This paper analyzes the cost-effectiveness of screening and treating diabetic retinopathy (DR) by simulating the disease progress continuously with existing data. A new computer simulation based on Monte Carlo techniques and logistic transformation follows cohorts from diabetes onset until death in five care scenarios. For younger-onset patients, ophthalmic care reduces the prevalence of blindness by 52% or greater while savings in disability facilities and production losses surpass direct costs. For older-onset patients, less favorable results appear. Financial benefits surpass costs for juvenile-onset patients. For other patients, the net costs of ophthalmic care seem lower than in other health care programs.

Objectives: The aim of this study was to examine the impact of the multi-hundred million dollar investment by the federal government in the developing Patient Outcomes Research Teams (PORTs) in over a dozen major academic medical centers in the United States throughout the 1990s. The objective of the PORTs was to reduce unnecessary clinical variation in medical treatment.

Methods: Using an economic derivation of welfare loss attributable to medical practice variation and hospital admission claims data for 2 million elderly patients generalizable to the nation, we estimate the change in welfare between 1991 and 2000, the period within which the PORTs were designed and executed and their results disseminated.

Results: Our results show inpatient admission types targeted by the PORTs did have less welfare loss relative to their total expenditure by 2000, but that there was not a net decrease in the welfare loss for all hospital admissions affected by the PORT.

Conclusions: We conclude that PORTs may have had favorable effects on welfare, most likely by reducing variation in clinical care, but that causality cannot be proved, and the effects were not equal across all conditions targeted by PORTs. This research provides a methodological template that may be used to evaluate the impact of patient safety research on welfare loss and on variation in medical treatment in both hospital and ambulatory settings.

Background: The intelligent bed is a medical bed with several home healthcare functions. It includes, among others, an “out of bed” detector, a moisture detector, and a catheter bag detector. The design purpose of the intelligent bed is to assist patients in their daily living, facilitate the work of clinical staff, and improves the quality of care. The aim of this sub-study of the iCare project was to explore how health professionals (HPs) experience and use the intelligent bed in patients’ homes.

Methods: The overall research design is inspired by case study methodology. A triangulation of data collection techniques has been used: log book, documentation study, participant observations (n = 45 hr), and qualitative interviews (n = 23). The data have been analyzed by means of Nvivo 9.0.

Findings: We identified several themes: HP transformation from passive technology recipient to innovator; individualized care; work flow redesign; and sensor technology intruding on patient privacy.

Conclusions: It is suggested that functions of the intelligent bed can result in more individualized care, workflow redesign, and time savings for the health professionals in caring for elderly patients. However, the technology intruded on patients’ privacy.

Objective: To identify training programs and educational resources in health technology assessment (HTA) in Europe.

Methods: A postal survey among potential informants in European countries and Israel, expanding on surveys among ISTAHC and INAHTA members. Informants were identified either using HTA networks or by means of Internet sources.

Results: The combined results of the three surveys show that in the European Union (EU), including Norway and Switzerland, 13 of 17 countries (76%) provide either university level courses or continuing education HTA courses. In the candidate EU countries, 4 of 10 countries (40%) provide HTA courses. In the remainder of countries, only Israel provides HTA courses. Ten different types of courses were identified, mainly applying traditional teaching methods. A substantial number of the courses were first organized in recent years. Many countries in central and eastern Europe expressed the wish to become more involved in HTA.

Conclusion: There is a rapid increase in the number and diversity of courses in HTA in Europe. In particular, countries in the EU are well represented. Education and training in HTA is scarce in EU candidate membership countries, and virtually absent in the remainder of countries. In general, HTA as a field is in the process of becoming established and institutionalized both in individual countries and internationally. To stimulate this development in the area of education and training, both bilateral cooperation and an EU-wide coordinated effort are recommended.

Two functions of home care, assistance to improve disabled and aged patients' mobility and function, and self-care that includes treatment, screening-monitoring, exercise assistance, and information exchange, are described, as are the technologies used for these functions. Social and economic pressures as well as professional rationales that expand the use of technologies at home are noted, as is their impact on the site of care and on the patient-doctor relationship.

Objectives: The aim of this study was to compare the clinical effectiveness and cost of percutaneous radiofrequency ablation (PRFA) and surgical resection (SRS) for the management of early stage Hepatocellular Carcinoma.

Methods: A systematic literature search of articles in English, French, and Chinese was performed using online databases. Only articles with patients classified as Child-Pugh Class A or B, with tumor size <5 cm were included. A meta-analysis was carried out to estimate the survival rate and disease-free survival rate following PRFA or SRS treatments. The cost of each treatment was estimated from the third party perspective. Univariate sensitivity analyses were used to study the relative importance of each component cost.

Results: We identified six studies (one randomized controlled trial (RCT) and five comparative cohort studies) meeting our inclusion criteria. There is good evidence that among Child-Pugh A patients for whom both SRS and PRFA are available options, survival rates following either procedure are comparable, while complications are more frequent and hospitalization longer following SRS. The evidence concerning recurrence rates and disease-free survival is less clear. Whereas the RCT indicates comparable outcomes with either procedure up to 3 years, the results of five cohort studies (with possible selection bias), particularly those with a mix of Child-Pugh A and B patients, favor the surgical option. SRS, costs approximately Canadian $8,275 more per case than PRFA.

Conclusions: Continuing doubts on this issue can only be resolved by a substantial RCT. Meanwhile, for early stage HCC patients classified as Child-Pugh A, who despite a possibly higher recurrence rate, prefer the less invasive PRFA to open surgery with its attendant risks, there is sufficient evidence to justify such a choice. For those classified as Child-Pugh (B) it is possible that overall survival is equally good with PRFA, but the evidence is less certain.

This article comments on the four country papers in this volume from an economic perspective. Different phases of the decision-making process, which can be supported by Health Technology Assessment (HTA), are considered. For each of these, there is large cross-country variation in the way in which HTA influences policy. Furthermore, economic themes regarding the relevance of HTA evidence for policy making, the position of cost-effectiveness in relation to other criteria vis-à-vis reimbursement decisions, the use of a cost per quality-adjusted life year threshold, and the incorporation of economic considerations in practice guidelines are discussed.

Motor vehicle crashes are a leading cause of morbidity and mortality. In the Haddon matrix, crashes are divided into three phases and factors affecting each phase. In the context of this matrix, the effectiveness, use, and legislation of safety belts and airbags are discussed, using process, injury, and economic outcome measures.

We evaluated the cost-effectiveness of (a) a vaccination program for the prevention of hepatitis B; and (b) the two commercially available vaccines (Merck Sharp and Dohme; Pasteur Institute) in Greece, a country of intermediate endemicity. We examined cases of hepatitis-B infection prevented and the expected medical costs among the high-risk groups of medical and nursing students, hospital personnel, and the general population. Employing a vaccination program reduces considerably the risk of infection, especially in the high-risk groups, while it increases the total cost. The vaccines are very comparable in terms of both health and economic outcomes. Sensitivity analysis indicated that vaccine cost, incidence of hepatitis B, and compliance were the key factors for the choice of (a) whether to undertake an extensive program to prevent hepatitis-B infection and its chronic sequelae; and (b) which vaccine to administer.

Both observational studies and nonrandomized controlled trials have found the presence of support during pregnancy to be associated with superior outcomes in terms of preventing abortion, extending the length of gestation, and reducing interventions in labor. However, randomized controlled trials of supportive interventions in pregnancy have not demonstrated any physical benefits from the interventions. It is also unlikely there are any significant adverse effects. Psychological benefits do appear to result from supportive interventions, including better enjoyment of the pregnancy and better postnatal status.

This review focuses on the component of health education directed at achieving changes in health behavior. Much of the work in this field has centered on health behavior that has a role in preventing future disease. Because the evidence is strongest in relation to coronary heart disease (17), considerable effort has been devoted to this area. Walter et ai. (34) indicated that the most relevant forms of health behavior to be considered in school-based programs on heart disease are those relating to diet, physical activity, and smoking. Programs relating to each of these behaviors are addressed here.

Hospital-based “firms” provide a means for combatting the fragmentation experienced by both patients and caregivers in the modern teaching hospital environment. A “firm” is an academic group practice that includes attending physicians, physician trainees, nurses, other staff, and patients. Each person's relationship with a firm lasts throughout his or her association with a particular institution. This article describes the firm system that was recently implemented on the Medical Service of the Cleveland VAMC. This system incorporates both inpatient and outpatient general medical services and provides for unbiased assignment of patients, physicians, and nurses.

This article presents an overview of technology assessment in the United States. The authors argue that while there are numerous institutions carrying out assessments, the United States requires an overall plan that would provide a national system for technology assessment. If technology assessment were more organized and systematized, the authors argue, it would be more efficient and would reach the public and the medical world effectively.

While international variations in intervention rates are well recognized, little is known about their implications for patient selection. This paper describes an exploratory study in which the probability of undergoing an elective intervention (surgery for benign prostatic hyperplasia) in an area in the United Kingdom was compared with an area in the United States. It found that the area with high intervention rates was associated with higher levels of surgery in men with low levels of need who are unlikely to gain much benefit.

In the past few years, empirical estimates of the marginal cost at which health care produces a quality-adjusted life year (QALY, k) have begun to emerge. In theory, these estimates could be used as cost-effectiveness thresholds by health-maximizing decision makers, but prioritization decisions in practice often include other considerations than just efficiency. Pharmaceutical reimbursement in Sweden is one such example, where the reimbursement authority (TLV) uses a threshold range to give priority to disease severity and rarity. In this paper, we argue that estimates of k should not be used to inform threshold ranges. Instead, they are better used directly in health technology assessment (HTA) to quantify how much health is forgone when a new technology is funded in place of other healthcare services. Using a recent decision made by TLV as a case, we show that an estimate of k for Sweden implies that reimbursement meant forgoing 8.6 QALYs for every QALY that was gained. Reporting cost-effectiveness evidence as QALYs forgone per QALY gained has several advantages: (i) it frames the decision as assigning an equity weight to QALYs gained, which is more transparent about the trade-off between equity and efficiency than determining a monetary cost per QALY threshold, (ii) it makes it less likely that decision makers neglect taking the opportunity cost of reimbursement into account by making it explicit, and (iii) it helps communicate the reason for sometimes denying reimbursement in a way that might be less objectionable to the public than current practice.

Background: Rapid on site evaluation (ROSE) allows immediate processing and interpretation of the aspirate in the procedural suite. It improves diagnostic yield and lowers patient care costs. There are limited data on its cost-effectiveness with endobronchial ultrasound (EBUS).

Methods: We developed an economic model with two arms, no ROSE (our current practice) and simulated ROSE. To simulate ROSE, a cytopathologist retrospectively identified the first diagnostic slide in each case. Using a decision analytic modeling technique under a hospital diagnostic unit perspective, the benefits of simulated ROSE were estimated as cost-savings. The model input was estimated from actual data, consulting experts, and the literature. The benefits were estimated as cost savings per patient and for the province of Alberta per year. Due to differences in the procedure, sarcoidosis and cancer patients were analyzed separately. The costs are shown in 2012 Canadian dollars, CAD.

Results: In our model without ROSE, the procedure cost/patient was CAD 646.00(USD 523.32) for cancer and CAD 1,170.00 (USD 947.73) for sarcoidosis. With simulated ROSE cost savings of CAD 63.00(37.00 to 89.00) [USD 51.04(29.97 to 72.10)], CAD 544.00(490.00 to 598.00) [USD 440.65(397.05 to 484.44)] for cancer and sarcoidosis, respectively. Extrapolating this to provincial data, our model estimates that EBUS with ROSE would lead to savings of CAD 50,000.00(30,000 to 71,000) [USD 40,501.24 (24,300.75 to 57,531.34)] for cancer and CAD 109,000.00 (87,000 to 130,000) [USD 88,337.07 (70,546.45 to 105,313.04) for sarcoidosis.

Conclusion: The use of ROSE with EBUS is cost saving. The projected savings were CAD 50,000.00 (USD 40,501.24) and CAD 109,000.00(USD 88,337.07) in cancer and sarcoidosis, respectively, for the province of Alberta, Canada.

In healthcare decision making, there is an important functional separation between assessment and appraisal. In the U.K. National Health Service (NHS), this distinction is illustrated by the separation of roles between the Health Technology Assessment Programme and the National Institute for Clinical Excellence. However, it can be seen at every level within the healthcare system. Assessment of a technology is a scientific task that synthesizes all relevant evidence on effectiveness and cost-effectiveness; its results are therefore generalizable. Appraisal of the technology is informed by the assessment but adds context-specific judgments on the applicability of the evidence, the feasibility and impact of alternative options, relative priorities, and wider social and ethical aspects. An explicit distinction between assessment and appraisal is helpful in achieving clarity, consistency, and consensus. It also makes clear the need for a wide range of assessment reviews to support decision making by commissioners, providers, and users of health services. Increasingly, the secondary research supported by the NHS R&D Programme is being distributed electronically. It is also being used to identify areas in which further primary research should be commissioned.

Objectives: The aim of this study was to determine adults’ Willingness To Pay (WTP) for CardioVascular Disease (CVD) intervention programs of different intensities.

Methods: Three hundred fourteen participants were randomized to two study conditions: (i) CVD risk assessment/communication; (ii) CVD risk assessment/communication + a behavior change program. The behavior change program was aimed at increasing physical activity, reducing saturated fat intake and smoking cessation. It consisted of a tailored Web site and individual coaching with a self-selected dose. At post-assessment, WTP and perceived autonomy support items were included. The intervention dose was registered throughout the trial and post-hoc intervention dose groups were created. Pearson Chi-Square tests, Student's t-tests, one-way analyses of variance were used to examine WTP-differences between the study conditions and intervention dose groups.

Results: Twenty-four months after baseline, 61 and 135 participants of the control and intervention condition, respectively, completed the questionnaires. No WTP difference was found between the study conditions. However, participants that selected a higher intervention dose were willing to pay significantly more for their program (p < .05).

Conclusions: In general, people want to pay the same amount of money for a CVD prevention program, irrespective of the inclusion of a behavior change program. However, there seems to be an association between the self-selected dose of the latter program and the WTP.
