Economic burden of hospital malnutrition and the cost–benefit of supplemental parenteral nutrition in critically ill patients in Latin America

Abstract

Aim: Disease-related malnutrition (DRM) is a prevalent condition that significantly increases the risk of adverse outcomes in hospitalized patients, particularly those with critical illness. Limited data is available on the economic burden of DRM and the cost–benefit of nutrition therapy in high-risk populations in Latin America. The aims of the present study were to estimate the economic burden of DRM and evaluate the cost–benefit of supplemental parenteral nutrition (SPN) in critically ill patients who fail to receive adequate nutrient intake from enteral nutrition (EN) in Latin America.

Methods: Country-specific cost and prevalence data from eight Latin American countries and clinical data from studies evaluating outcomes in patients with DRM were used to estimate the costs associated with DRM in public hospitals. A deterministic decision model based on clinical outcomes from a randomized controlled study and country-specific cost data were developed to examine the cost–benefit of administering SPN to critically ill adults who fail to reach ≥60% of the calculated energy target with EN.

Results: The estimated annual economic burden of DRM in public hospitals in Latin America is $10.19 billion (range, $8.44 billion–$11.72 billion). Critically ill patients account for a disproportionate share of the costs, with a 6.5-fold higher average cost per patient compared with those in the ward ($5488.35 vs. $839.76). Model-derived estimates for clinical outcomes and resource utilization showed that administration of SPN to critically ill patients who fail to receive the targeted energy delivery with EN would result in an annual cost reduction of $10.2 million compared with continued administration of EN alone.

Limitations: The cost calculation was limited to the average daily cost of stay and antibiotic use. The costs associated with other common complications of DRM, such as prolonged duration of mechanical ventilation or more frequent readmission, are unknown.

Conclusions: DRM imposes a substantial economic burden on Latin American countries, with critically ill patients accounting for a disproportionate share of costs. Cost–benefit analysis suggests that both improved clinical outcomes and significant cost savings can be achieved through the adoption of SPN as a therapeutic strategy in critically ill patients who fail to receive adequate nutrient intake from EN.     

EU telecommunications and electricity markets—Heading towards price convergence?

This paper investigates the sources of intra-EU price dispersion in two important network industries, namely telecommunications and electricity. Both sectors experienced substantial regulatory reforms over the past couple of years, resulting in the widespread introduction of competition in traditionally monopolistic markets. The empirical results reported in this paper confirm that the introduction of competition in these sectors resulted in significant downward price effects. Further progress with regulatory reforms in telecommunications and electricity is likely to result in further price falls in these sectors and reduced price level differences across EU Member States.

The effects of perceived value on loyalty: the moderating effect of market orientation adoption

This paper aims to identify the moderating effect of service firms’ adoption of market orientation on key variables of consumer behavior, namely perceived value and loyalty. The study took a business-to-customer perspective. First, the adoption of market orientation was measured, from the firm’s point of view. Second, customer perceptions were analyzed, using the two variables perceived value and loyalty. The sample comprised 100 service firms and 572 of their customers. The present work provides original insights, identifying that the effect of perceived value on loyalty depends on other variables external to the consumer, such as the market orientation approach.     

Impact of Market Orientation and ICT on the Performance of Rural Smaller Service Enterprises*

Market orientation (MO) is considered as a competitive strategy for the smaller service enterprises based in rural locations. A model is proposed and validated for the rural tourism sector that encompasses the effects of MO and of the use of information and communications technology (ICT) on business activity, taking into account the business's financial results, improvements to the rural location, and the more personal, intangible impact on the local entrepreneur. ICT is found to have a positive impact on MO and outcomes, whereas, similarly, the adoption of MO is found to have a positive effect on outcomes.     

Metropolregionen: Impulsgeber für Strukturwandel und wirtschaftliche Entwicklung

Urban centres and their surroundings often act as highly dynamic economic areas. Due to continuing urban migration, population growth as well as their heightened potential for employment, they have significant impact on Germany’s overall economic performance. Cities benefit from their neighbouring regions via a division of labour based on functional and spatial comparative advantages. Jobs in the service sector are concentrated in the city, while surrounding regions show a relatively high specialisation in the industrial sector. The economic development of metropolitan regions can be fostered particularly by improving supra-regional metropolitan functions related to education and to research and development. Moreover, the improvement of the intra-regional infrastructure also contributes to the economic strength of the whole metropolitan area.     

Influence of Affective Traits on Entrepreneur's Goals and Satisfaction

Emotions are important to an individual's behavior. However, affective elements have rarely been included in the analysis of entrepreneurs' behavior. Using a sample of 335 entrepreneurs from multiple industries of the Spanish region of Castile and León, we analyze the role of emotions in entrepreneurs' statement of goals and in their satisfaction with business performance. The results show that positive affective traits influence an entrepreneur to state broad and ambitious goals, and personal negative affective traits influence an entrepreneur to state a narrow set of goals. We also find that positive (negative) affective traits are positively (negatively) related to entrepreneur satisfaction.     

The influence of job characteristics and self‐directed learning orientation on workplace learning

Given the increasing importance of learning at work, we set out to examine the factors which influence workplace learning behaviour. The study investigated the influence of the job characteristics from Karasek's Job Demand Control Support model and the personal characteristic self‐directed learning orientation on workplace learning. A total of 837 workers, aged between 18 and 65, from different sectors and with different educational levels completed a paper questionnaire. Analysis revealed that job demands and self‐directed learning orientation constitute significant and positive predictors of workplace learning behaviour. The study can help organizations to create job structures that promote workplace learning.     

Mitigating information asymmetry through sustainability assurance: The role of accountants and levels of assurance

This paper aims to examine the usefulness of sustainability reporting in reducing information asymmetry as result of lower dispersion and higher accuracy in financial analysts’ earnings forecasts. The empirical results from an international sample of listed companies indicate that the disclosure of sustainability information alone is not sufficient in this regard as our findings indicate that information asymmetry is reduced to a greater when such information is assured, supporting the value relevance role of sustainability reporting and assurance. In addition, the empirical findings suggest differences in terms of assurance attributes (provider and level of engagement) and such differences are even more relevant when controlling the institutional context. Assurance is highly appreciated by investors in more stakeholder-oriented countries; however, in more shareholder-oriented environments, assurance affects information asymmetries only when it is provided by accounting professionals who also report a “reasonable” opinion.     

Service quality control mechanisms in franchise networks

This paper reports the study of some factors that influence the control intensity exerted by franchisors on the service quality provided by the franchised units of their networks and what interdependencies exist between the different mechanisms that can be used to monitor service quality. On the one hand, three control mechanisms of conformance quality are considered, namely audits, mystery shoppers, and mandatory purchase of inputs and products. On the other hand, polls are used to monitor perceived quality by customers. There are two main findings. First, control intensity is greater in those industries in which customers tend to be non-repetitive. Second, four complementary relationships are found between control mechanisms: between audits and mystery shoppers, between audits and polls, between mandatory purchase of inputs or products and mystery shoppers, and between mandatory purchase of inputs or products and polls.     

Price assessments by consumers: influence of purchase context and price structure

Among the numerous factors that influence decisions on prices, consumer behaviour has special significance. This paper reviews and analyses relevant studies conducted during the last few decades. On the basis of our analysis, four categories of factors that determine consumer behaviour have been identified. Additionally, we have developed an experimental research design to analyse the influence that the following factors have on price perception: price structure (i.e. price level, order of presentation and price differences), purchase context (i.e. reason for purchase or product use) and demographic characteristics (i.e. gender). Results reveal a significant influence of these variables on consumer behaviour.
