Aims/hypothesis:Continuous subcutaneous insulin infusion (CSII) is an important treatment option for type 1 diabetes patients unable to achieve adequate glycemic control with multiple daily injections (MDI). Combining CSII with continuous glucose monitoring (CGM) in sensor-augmented pump therapy (SAP) with a low glucose-suspend (LGS) feature may further improve glycemic control and reduce the frequency of hypoglycemia. A cost-effectiveness analysis of SAP?+?LGS vs CSII plus self-monitoring of blood glucose (SMBG) was performed to determine the health economic benefits of SAP?+?LGS in type 1 diabetes patients using CSII in the UK.Methods:Cost-effectiveness analysis was performed using the CORE diabetes model. Treatment effects were sourced from the literature, where SAP?+?LGS was associated with a projected HbA1c reduction of ?1.49% vs ?0.62% for CSII, and a reduced frequency of severe hypoglycemia. The time horizon was that of patient lifetimes; future costs and clinical outcomes were discounted at 3.5% and 1.5% per annum, respectively.Results:Projected outcomes showed that SAP?+?LGS was associated with higher mean quality-adjusted life expectancy (17.9 vs 14.9 quality-adjusted life years [QALYs], SAP?+?LGS vs CSII), and higher life expectancy (23.8 vs 21.9 years), but higher mean lifetime direct costs (GBP 125,559 vs GBP 88,991), leading to an incremental cost-effectiveness ratio (ICER) of GBP 12,233 per QALY gained for SAP?+?LGS vs CSII. Findings of the base-case analysis remained robust in sensitivity analyses.Conclusions/interpretation:For UK-based type 1 diabetes patients with poor glycemic control, the use of SAP?+?LGS is likely to be cost-effective compared with CSII plus SMBG. 相似文献

In this paper, the procedures and problems of the changeover to the euro are reviewed. The legal elements involved are discussed as are the psychological aspects. Various practical problems and proposed solutions are described. The possibility of resistance from the consumers in certain segments of the Member State populations is also addressed. One reason for any such resistance might be that for many citizens, the change of currency appears to have little bearing on their everyday concerns.Particular attention is devoted to the scenario for the period 1 January to 1 July 2002, during which coins and notes in euros and national monetary units can be in circulation at the same time. 相似文献

Imitation goods are widely spread throughout the global business world. Shanzhai imitation () represents a type of imitation that mimics the original brand through surface or functional similarities but often provides enhanced or innovative features adapted to local market needs. Although both practitioners and academics have studied and provided solutions to combat counterfeits, solutions for original brand manufacturers to address threats from Shanzhai products are lacking. In this article, we first differentiate Shanzhai products from counterfeits. Using a mixed-method approach that combines interviews and laboratory experiment results, we then identify social, individual, functional, and financial (SIFF) factors as driving forces behind consumers’ purchasing of Shanzhai products. Shanzhai buyers place more weight on functional value and price/quality ratio than do counterfeit buyers, who in turn favor social value and materialism more than Shanzhai buyers. Finally, we provide several recommendations to original manufacturers from both the demand and supply sides. 相似文献

RESUME 1 : Cet article propose une étude du rôle croissant que joue l’évaluation dans la gouvernance des services à domicile en Europe. L’introduction de quasi‐marchés dans plusieurs pays européens va de pair avec un processus d’autonomisation de la fonction d’évaluation qui devient un véritable outil de régulation de la concurrence. Une analyse comparée des situations en Belgique, France et Royaume‐Uni, tant de la demande que de l’offre de services, met en évidence les tensions récurrentes dans les objectifs de l’évaluation (qualité des services, maîtrise des budgets sociaux, création d’emploi), la faible prise en compte de la qualité de l’emploi ainsi que les limites des dispositifs standardisés d’évaluation au regard de la rhétorique du libre choix de l’usager (consommateur). 相似文献

ABSTRACT 1 : In 2001, the Belgian government introduced a ‘service voucher’ scheme in the field of domestic (housework) services, following a quasi‐market mechanism which fosters competition between providers of different types as regards sector (for‐profit, public, third sector) and mission (seeking profits, home care provision to vulnerable groups and work integration of the unemployed). Empirical evidence suggests that third sector organizations focusing on a social mission recognized by a tutelary regulation are the best performing with regards to the quality of jobs and service organization, leading to a better ‘triangulation’ of the service relationship. On the other hand, for‐profit providers, especially temporary work agencies, seem to favour their capacity of adaptation to the desiderata of their clients and costs’ minimization to the detriment of the quality of jobs which are made as flexible as possible. 相似文献

In this article, we show that the effect of product diversification on performance is not homogeneous across countries. Diversified insurance companies perform significantly worse than their focused competitors in countries with well‐developed capital markets, high levels of property rights protection, and high levels of competition. In addition, we find that the diversification–performance relationship for insurance companies depends on company size. For large insurers operating in countries with less developed capital markets, diversification significantly increases performance. Our results suggest that the optimal organizational structure may be different for insurers operating in emerging economies than for insurers operating in developed countries. 相似文献

The goal of this research is to identify drivers that influence the brand success, in order to develop a more effective business strategy. An abductive theory approach is adopted and food managers from Italy and Sweden were questioned. The authors modeled the eight correlated first-order factors, using seven independent variables and the dependent variable brand success. The variance-based structural equation modeling approach (partial least square [PLS] algorithm) have been applied. This study provides insight and empirical evidence on brand success. The findings can be employed as more effective brand strategies in a sector that has been under-investigated in academic literature and practice. 相似文献
