An economic paradigm for nurse practitioner program development.

In 1987 a collaborative nurse practitioner program was developed and implemented by George Mason University, a public institution, and The George Washington University, a private institution. Three economic factors affecting decisions related to the development of the collaborative program are discussed: (1) optimal use of resources, (2) consumer and institutional utility, and (3) demand for the program. Optimal use of resources was based on collaboration in the areas of faculty and administrative resources and existing curriculum, thereby reducing the cost burden at each institution. From the perspective of consumer and institutional utility, the program was structured financially to enhance the well-being of students and both institutions. Finally, the consumer demand for the program was addressed by maintaining the higher proportion of credits at the lower-cost institution, thus enabling more students to afford the program. The success of the institutions in addressing the economic factors noted above can serve as a paradigm for program development in other universities and graduate programs.

Current costing models: are they suitable for allocating health resources? The example of fall injury prevention in Australia.

The example of fall injury among older people is used to define and illustrate how current Australian systems for allocation of health resources perform for funding emerging public health issues. While the examples are Australian, the allocation and priority setting methods are common in the health sector in all developed western nations. With an ageing population the number of falls injuries in Australia and the cost of treatment will rise dramatically over the next 20-50 years. Current methods of allocating funds within the health system are not well suited to meeting this coming epidemic. The information requirements for cost-benefit and cost-effectiveness measures cannot be met. Marginal approaches to health funding are likely to continue to fund already well-funded treatment or politically driven prevention processes and to miss the opportunity for new prevention initiatives in areas that do not have a high political profile. Fall injury is one of many emerging areas that struggle to make claims for funding because the critical mass of intervention and evidence of its impact is not available. The beneficiaries of allocation failure may be those who treat the disease burden that could have been easily prevented. Changes to allocation mechanisms, data systems and new initiative funding practices are required to ensure that preventative strategies are able to compete on an equal footing with treatment approaches for mainstream health funding.

Drink driving enforcement and publicity campaigns: are the policy recommendations sensitive to model specification?

Since their implementation, the drink driving enforcement and publicity campaigns in the Australian State of Victoria have been extensively evaluated and the mixed results obtained have generated much public debate. Using the same data from previous studies, this paper re-evaluated the effectiveness of the campaigns and tested several model assumptions and specifications. In general, the results obtained were robust and showed that the campaigns were effective in reducing serious crashes during high alcohol hours.

The cost-utility of photodynamic therapy in eyes with neovascular macular degeneration--a value-based reappraisal with 5-year data.

PURPOSE: To assess the value conferred by photodynamic therapy (PDT) and the cost-utility of PDT for the treatment of classic, subfoveal choroidal neovascularization associated with age-related macular degeneration (ARMD). DESIGN: Average cost-utility analysis utilizing clinical trial data, patient-based time tradeoff utility preferences, and a third party insurer cost perspective. METHODS: Five-year visual acuity data from the TAP (Treatment of Age-related Macular Degeneration With Photodynamic Therapy) Investigation were modeled into a 12-year, value-based, reference case, cost-utility model utilizing year 2004 Medicare costs and an outcome of dollar/QALY (dollars/quality-adjusted life-year). Discounting of outcomes and costs using net present value analysis with a 3% annual rate was performed as recommended by the Panel for Cost-Effectiveness in Health and Medicine. RESULTS: PDT with verteporfin (Visudyne) dye for classic subfoveal choroidal neovascularization confers an 8.1% quality of life (value) improvement over the 12-year life expectancy of the reference case, while during the last 8 years the value improvement is 9.5%. The average cost-utility of the intervention is dollar 31,103/QALY (quality-adjusted life-year). Extensive one-way sensitivity analysis values range from dollar 20,736/QALY if treatment efficacy is increased by 50% to dollar 62,207 if treatment efficacy is decreased by 50%, indicating robustness of the model. CONCLUSIONS: PDT using verteporfin dye to treat classic subfoveal choroidal neovascularization is a very cost-effective treatment by conventional standards. The marked improvement in cost-effectiveness compared with a previous report results from the facts that the treatment benefit increasingly accrues during 5 years of follow-up while the number of yearly treatments diminishes markedly during that time.

Cost-effectiveness and contraceptive effectiveness of the transdermal contraceptive patch.

OBJECTIVE: The purpose of this study was to examine implications of increased perfect use on the cost-effectiveness of the contraceptive patch compared with combination oral contraceptives (COCs). STUDY DESIGN: This study compared the patch with low-estrogen-dose COCs. It assumes that the risks of developing a medical condition during use are the same for both the patch and COCs. Differences in net cost and pregnancies avoided during use were modeled. With the use of a pharmacoeconomic model, both methods were compared with a hypothetical reference case of contraception nonuse. The base-case model considered women, ages 15 to 50, in average health in a long-term, mutually monogamous, heterosexual relationship. RESULTS: The base-case analysis showed that use of the patch resulted in a savings of 249 US dollars and 0.03 pregnancies per woman over 2 years compared with COCs. CONCLUSION: This analysis demonstrated that patch use would be cost saving compared with COC use, resulting in a net avoidance of pregnancy for this population. The cost savings are attributed to reduced costs of pregnancy.

Repeated tobacco-use screening and intervention in clinical practice: health impact and cost effectiveness.

BACKGROUND: This report updates 2001 estimates of disease burden prevented and cost effectiveness of tobacco-use screening and brief intervention relative to that of other clinical preventive services. It also addresses repeated counseling because the literature has focused on single episodes of treatment, while in reality that is neither desirable nor likely. METHODS: Literature searches led to four models for calculating the clinically preventable burden of deaths and morbidity from smoking as well as the cost effectiveness of providing the service annually over time. The same methods were used in similar calculations for other preventive services to facilitate comparison. RESULTS: Using methods consistent with existing literature for this service, an estimated 190,000 undiscounted quality-adjusted life years (QALYs) are saved at a cost of $1100 per QALY saved (discounted). These estimates exclude financial savings from smoking-attributable disease prevented and use the average 12-month quit rate in clinical practice for tobacco screening and brief cessation counseling with cessation medications (5.0%) and without (2.4%). Including the savings of prevented smoking-attributable disease and using the effectiveness of repeated interventions over the lifetime of smokers (23.1%), 2.47 million QALYs are saved at a cost savings of $500 per smoker who receives the service. CONCLUSIONS: This analysis makes repeated clinical tobacco-cessation counseling one of the three most important and cost-effective preventive services that can be provided in medical practice. Greater efforts are needed to achieve more of this potential value by increasing current low levels of performance.

Epidemiologic changes and economic burden of hypertension in Latin America: evidence from Mexico.

BACKGROUND: Costs of health services for hypertension and the financial consequences of epidemiologic changes in this disease are important concerns for health systems in Latin America. METHODS: We conducted longitudinal analyses of the economic impact of the epidemiologic changes on health care services for hypertension in the Mexican health care system. The cost evaluation method used was based on costing technique by production function and consensus techniques. To estimate the epidemiologic changes and financial consequences for the period 2005 to 2007, three probabilistic models were constructed according to the Box-Jenkins technique. RESULTS: If changes are not implemented in prevention programs to reduce the effects of current risk factors, there will be increases in the number of patients with hypertension as well as in the financial burden to treat the disease. The amount allocated for hypertension in 2007, which will be 6% to 8% of the total health budget, is US$ 2,486,145,132. Of these, US$ 1,178,725,132 will be direct costs and US$ 1,307,420,000 will be indirect costs. Regarding epidemiologic changes for 2005 v 2007 (P < .05), an increase is expected, although results show a greater increase in insured populations. CONCLUSIONS: If the risk factors and different health programs remain as they currently are, the economic impact of expected epidemiologic changes on the social security system will be particularly strong. Another relevant financial factor is the appearance of internal competition in the allocation of financial resources among the main providers of health services for hypertension; this factor becomes even more complicated within each provider.

Lifetime implications and cost-effectiveness of using finasteride to prevent prostate cancer.

PURPOSE: We estimate the lifetime implications of daily treatment with finasteride following the results of the Prostate Cancer Prevention Trial (PCPT). In this trial, prostate cancer prevalence was reduced by 25%; however, an increase in the number of high-grade tumors among the treatment group necessitates the long-term projection of the likely benefits and costs. METHODS: We use a Markov decision analysis model with data from the trial, the SEER program, and published literature. The model measures the cost per life-year and cost per quality-adjusted life-year (QALY) gained for a cohort of men age 55 years who initiate preventive treatment with finasteride. RESULTS: Finasteride is associated with a gain of 6 life-years per 1000 men treated at an incremental cost of 1660000 dollars per life-year gained. The quality-adjusted analysis results in 46 QALYs gained per 1000 men treated at an incremental cost of 200000 dollars per QALY gained, due primarily to the favorable effects of finasteride on benign prostatic hyperplasia. Under the assumption that the increase in high-grade tumors observed among finasteride treated men is a pathologic artifact, the incremental costs are 290000 dollars per life-year gained and 130000 dollars per QALY gained. CONCLUSIONS: The cost burden associated with finasteride is substantial, while its survival benefit is small and only realized many years after initiating treatment. To achieve an incremental cost below 100000 dollars per QALY gained, the price of finasteride must be reduced by 50% from its current average wholesale price and finasteride must be shown to prevent high-grade as well as low-grade disease.

Changes in mortality after the recent economic crisis in South Korea.

PURPOSE: To examine the changes in all cause mortality and cause-specific mortality after the economic crisis in South Korea. METHODS: Monthly mortality data for an entire country was used and intervention analysis applied to compare mortality after the crisis with mortality which would have occurred if the trends before the crisis had continued. RESULTS: All cause mortality began to increase about 1 year after the crisis, while cardiovascular increased immediately. Transport accidents decreased significantly during the year following the crisis and then regressed towards the pre-economic crisis level. Suicides increased rapidly and maintained an upward trend but subsequently reduced towards the pre-economic crisis level. CONCLUSIONS: This study has shown an evidence of a relationship between economic crisis and mortality.

Endogeneity bias in the absence of unobserved heterogeneity.

PURPOSE: To demonstrate that endogeneity bias can still arise even when no unobserved heterogeneity exists. METHODS: A formal mathematical proof and a Monte Carlo simulation are used to demonstrate that ordinary estimation techniques will generate biased parameter estimates. RESULTS: The Monte Carlo results support the formal proof. Even in the absence of unobserved heterogeneity, ordinary least squares estimation that does not account for the endogenous nature of an explanatory variable resulted in a parameter estimate for the endogenous variable that was significantly biased (by a factor of 1.42 for the simple model and 1.98 for the saturated model). Alternatively, controlling for endogeneity using the instrumental variables approach led to an unbiased parameter estimate. CONCLUSIONS: Endogeneity bias can still occur even when unobserved heterogeneity is not present.

A comparison of the expected costs of high dose rate brachytherapy using 252Cf versus 192Ir.

A cost analysis to compare high dose rate (HDR) brachytherapy using either californium-252 (252Cf) or 192Ir was performed to determine the prospects of widespread clinical implementation of HDR 252Cf. Interest in the neutron-emitting 252Cf radioisotope as a radiotherapy nuclide has undergone a resurgence given recent efforts to fabricate HDR remotely afterloaded sources, and other efforts to create a miniature source for improved accessibility to a variety of anatomic sites. Therefore, HDR 252Cf brachytherapy may prove to be a potential rival to the use of HDR 192Ir remotely afterloaded brachytherapy--the current standard-of-care treatment modality using HDR brachytherapy. Considering the possible improvements in clinical efficacy using HDR 252Cf brachytherapy and the enormous costs of other high-LET radiation sources, the cost differences between 252Cf and 192Ir may be well-justified.

Refining sweet sorghum to ethanol and sugar: economic trade-offs in the context of North China.

Reducing the use of non-renewable fossil energy reserves together with improving the environment are two important reasons that drive interest in the use of bioethanol as an automotive fuel. Conversion of sugar and starch to ethanol has been proven at an industrial scale in Brazil and the United States, respectively, and this alcohol has been able to compete with conventional gasoline due to various incentives. In this paper, we examined making ethanol from the sugar extracted from the juice of sweet sorghum and/or from the hemicellulose and cellulose in the residual sorghum bagasse versus selling the sugar from the juice or burning the bagasse to make electricity in four scenarios in the context of North China. In general terms, the production of ethanol from the hemicellulose and cellulose in bagasse was more favorable than burning it to make power, but the relative merits of making ethanol or sugar from the juice was very sensitive to the price of sugar in China. This result was confirmed by both process economics and analysis of opportunity costs. Thus, a flexible plant capable of making both sugar and fuel-ethanol from the juice is recommended. Overall, ethanol production from sorghum bagasse appears very favorable, but other agricultural residues such as corn stover and rice hulls would likely provide a more attractive feedstock for making ethanol in the medium and long term due to their extensive availability in North China and their independence from other markets. Furthermore, the process for residue conversion was based on particular design assumptions, and other technologies could enhance competitiveness while considerations such as perceived risk could impede applications.

Economic implications of extended-release metoprolol succinate for heart failure in the MERIT-HF trial: a US perspective of the MERIT-HF trial.

BACKGROUND: The MERIT-HF trial demonstrated improved survival and fewer hospitalizations for worsening heart failure with extended-release (ER) metoprolol succinate in patients with heart failure. This study sought to estimate the economic implications of this trial from a US perspective. METHODS AND RESULTS: A discrete event simulation was developed to examine the course of patients with heart failure. Characteristics of the population modeled, probabilities of hospitalization and death with standard therapy, and risk reductions with ER metoprolol succinate were obtained from Metoprolol CR/XL Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF) and evaluated in weekly cycles. Direct medical costs were estimated from US databases in 2001 US dollars. Uncertainty in inputs was incorporated and analyses were carried out to estimate events prevented total and net costs. The model predicts that ER metoprolol succinate will prevent approximately 7 deaths and 15 hospitalizations from heart failure per 100 patients over 2 years. Compared with standard therapy alone, this translates to a cost reduction between $395 and $1112 per patient, depending on whether the costs of hospitalizations for other causes are included. Savings were maintained in 90% of the simulations. CONCLUSION: This analysis predicts that the positive effect of ER metoprolol succinate on mortality and morbidity demonstrated in MERIT-HF leads to substantial savings.

Socio-economic factors and health care system characteristics related to cancer survival in the elderly. A population-based analysis in 16 European countries (ELDCARE project).

The ELDCARE study aims to investigate, at the ecological level, the relationships between socio-economic variables and cancer survival in patients aged 65 years and over. Survival data for patients diagnosed during the period 1985-1989 and followed up to 1994 were provided by 43 European Cancer Registries in 16 countries participating in the EUROCARE 2 project. Relative survival was computed by Hakulinen's methods. Data on socio-economic factors were collected by national statistics offices for the years around 1991. Pearson's correlation was used to study the relationships between cancer survival and socio-economic factors. We selected four groups of variables. The first group included macro-economic variables (such as Gross Domestic Product, GDP; Total Health Expenditure, THE); the second, the main characteristics of national health care systems; the third, demographic factors; and the fourth, variables on labour market organisation. The countries with the largest proportions of elderly populations, in Northern and Western Europe, spent more on health than the less affluent countries of Eastern Europe. GDP was strongly related to THE but a very high variability in Computed Tomography Scanners (CTS) among countries with similar THE was observed. Indeed, those countries with THE around US 1500 dollars per capita had survival rates for breast cancer ranging from 67 to 82%. Cancer survival in elderly patients in Europe was most strongly related to GDP and THE, especially for good prognosis cancers. Survival was strongly correlated with health care technologies, particularly CTS, but not with health employment. Survival was positively correlated with proportion of married elderly people (and negatively with widowed elderly), suggesting a role played by social support in influencing the prognosis of elderly patients. These results highlight how health outcomes in the elderly are a complex phenomenon, not determined only by GDP and THE, but affected by social organisation and life habits as well as economic development conditions.

Deaths rise in good economic times: evidence from the OECD.

This study uses aggregate data for 23 Organization for Economic Cooperation and Development (OECD) countries over the 1960-1997 period to examine the relationship between macroeconomic conditions and deaths. The main finding is that total mortality and deaths from several common causes rise when labor markets strengthen. For instance, controlling for year effects, location fixed-effects (FE), country-specific time trends and demographic characteristics, a 1% point decrease in the national unemployment rate is associated with growth of 0.4% in total mortality and the following increases in cause-specific mortality: 0.4% for cardiovascular disease, 1.1% for influenza/pneumonia, 1.8% for liver disease, 2.1% for motor vehicle deaths, and 0.8% for other accidents. These effects are particularly pronounced for countries with weak social insurance systems, as proxied by public social expenditure as a share of GDP. The findings are consistent with evidence provided by other recent research and cast doubt on the hypothesis that economic downturns have negative effects on physical health.
