AbstractBackground: Heart failure (HF) is a common, serious disease in the US and Europe. Patients with HF often require treatment for fluid overload, resulting in costly inpatient visits; however, limited evidence exists on the costs of alternative treatments. This study performed a cost-analysis of ultrafiltration (UF) vs diuretic therapy (DIUR-T) for patients with HF from the hospital perspective.Methods: The model used clinical data from the literature and hospital data from the Healthcare Cost and Utilization Project to follow a decision-analytic framework reflecting treatment decisions, probabilistic outcomes, and associated costs for treating patients with HF and hypervolemia with veno-venous UF or intravenous DIUR-T. A 90-day timeframe was considered to account for hospital readmissions beyond 30?days. Sensitivity and scenario analyses were performed to gauge the robustness of the results.Results: Although initial hospitalization costs were higher, fluid removal by UF reduced hospital readmission days, leading to cost savings of $3,975 (14.4%) at the 90-day follow-up (UF costs, $23,633; DIUR-T costs, $27,608).Conclusions: UF is a viable alternative to DIUR-T when treating fluid overload in HF patients because it reduces hospital readmission rates and durations, which substantially lowers costs over a 90-day period compared to DIUR-T. 相似文献

We address the problem of ranking distributions of attributes in terms of poverty, when the attributes are represented by binary variables. To accomplish this task, we identify a suitable notion of “multidimensional poverty line” and characterize axiomatically the Head-Count and the Attribute-Gap poverty rankings, which are the natural counterparts of the most widely used income poverty indices. Finally, we apply our methodology and compare our empirical results with those obtained with some other well-known poverty measures. 相似文献

In malaria‐endemic countries about a quarter of test‐negative individuals take antimalarials (artemisinin‐based combination therapies [ACTs]). ACT overuse depletes scarce resources for subsidies and contributes to parasite resistance. As part of an experiment in Kenya that provided subsidies for rapid diagnostic test and/or for ACTs conditionally on being positive, we studied the association between beliefs on malaria status (prior and posterior the intervention) and decisions to get tested and to purchase ACTs. We find that prior beliefs do not explain the decision of getting tested (conditional on the price) and nonadherence to a negative test. However, test‐negative individuals who purchase ACTs report higher posterior beliefs than those who do not, consistent with a framework in which the formers revise beliefs upward, while the latters do not change or revise downward. We also do not find evidence that prior beliefs on ACT effectiveness and trust in test results play any major role in explaining testing or treatment behavior. Further research is needed to improve adherence to malaria‐negative test results. 相似文献

In recent years, the stakeholder approach has been widely applied in the debate on corporate social responsibility (CSR).
Although many authors of this approach have reviewed many elements of the model, they have unconditionally accepted several
criteria assumed by Freeman (1984) to identify stakeholders. In general, stakeholder authors have assumed that (a) the company establishes dyadic relationships with other agents, and (b) decisions made by a company only have foreseen and direct effects on other agents. These criteria have enabled researchers to understand simple processes. However, they have also prevented
researchers from explaining how action comes about, and how responsibility is shared, in many complex processes taking place
in contemporary societies. Such complex processes involve many agents, and each decision can generate unexpected effects which
accumulate or disseminate. Furthermore, the normative structure governing these processes can affect and/or be affected by
the actions of agents. In this study, we propose new criteria to expand the stakeholder model and facilitate the study of
CSR in such processes. 相似文献

This paper explores how marketing capabilities contribute to the international expansion of international new ventures, and influence their choice of entry mode. The study examines how marketing capabilities help international new ventures to use entry modes involving higher resource commitment in international markets. The proposed model was tested on country-level data from Spain. The results show that marketing capabilities contribute to a firm's decision to choose entry modes involving higher resource commitment in foreign markets. The paper also includes insights on antecedents of international new ventures’ choice of entry modes in foreign markets. 相似文献
