Use of the THERMOCOOL SMARTTOUCH catheter for ablation of atrial fibrillation: the relationship between hospital procedure volume,re-admissions,and economic outcomes

Objective: The purpose of this study was to examine the relationship between hospital volume of prior THERMOCOOL SMARTTOUCH catheter use and health and economic outcomes among hospitalized patients with atrial fibrillation (AF) undergoing ablation using this device.

Materials and methods: Patients aged ≥18 years with a primary diagnosis of AF undergoing ablation treatment using the THERMOCOOL SMARTTOUCH catheter between January 2014 and June 2016 were identified from the Premier hospital database with the first date of such a procedure being defined as the index date. Hospital volume of prior THERMOCOOL SMARTTOUCH catheter use was determined during the 12-month pre-index period, and was classified into five groups: no volume (0), low volume (1–50), mid volume (51–100), high volume (101–150), and very high volume (≥151). Outcomes, including length of stay (LOS; for inpatient procedure only), hospital costs (total, hospital pharmacy, supply), and all-cause re-admission were evaluated. A generalized estimating equation (GEE) with exchangeable correlation structure was used to examine the impact of hospital volume on LOS, hospital costs, and re-admissions controlling for hospital clustering and other covariates.

Results: The study population included 640 hospitalized AF patients. The adjusted mean LOS was significantly shorter in very high-volume hospitals than hospitals with no volume (mean LOS 2.30 vs 4.33 days; p?=?.0377). As volume increased, the mean adjusted supply cost tended to decrease, although these changes emerged as non-significant. The 12-month all-cause re-admission was significantly lower among patients undergoing ablation in low (Odds ratio [OR]?=?0.27; confidence interval [CI]?=?0.08–0.85) and mid (OR?=?0.12; CI?=?0.02–0.61) volume hospitals compared to hospitals with no volume.

Limitations: Study results may not be generalizable to all US hospitals.

Conclusions: Among AF patients undergoing ablation, increased hospital volume of prior THERMOCOOL SMARTTOUCH catheter use was associated with shorter LOS and a lower likelihood of all-cause re-admission.     

Microeconomic mechanisms behind export spillovers from FDI: evidence from Bulgaria

This paper studies how the presence of multinational enterprises affects the export performance of Bulgarian manufacturing firms—export spillovers from FDI. Using export data at the firm/product/destination level for the period 2004–2006, it finds positive forward spillover on export value and quantity, related to quality upgrading. Conversely, it finds negative (or insignificant) backward and horizontal spillover on export flows, related to quality downgrading. When aggregating data at the firm level and considering that a firm can operate in several sectors, the paper shows that the presence of foreign input suppliers allows domestic firms to export additional varieties of lower quality and upgrade the average quality of existing varieties, whereas the presence of foreign customers generates the opposite effect.     

Attributions and behavioral intentions of inexperienced salespersons to failure: An empirical investigation

The goal of this research was to determine how inexperienced sales representatives (rookies) interpret and respond to their sales failure situations. The authors studied 296 rookie financial services sales representatives'performance attributions for a previous unsuccessful sales interaction and their intended behaviors for a future, similar selling situation. This provided the authors the opportunity to compare their results with Dixon, Spiro and Jamil's (2001) findings for experienced sales representatives (veterans). In the event of a sales failure, rookies'responses do not parallel those of veterans. The results suggest that rookies are likely to engage in several inappropriate behaviors in response to failed sales encounters. Implications for managers and directions for future research are discussed. Andrea L. Dixon (Andrea.

Investment allocation: A comparison of the reform experiences of Hungary and Yugoslavia

Both Yugoslavia and Hungary, despite reform efforts, have continued to exhibit investment cycles. An analysis is presented of why the Yugoslav and Hungarian experiences have been so similar despite major institutional differences. An examination of three different capital allocation systems in Yugoslavia identifies both institutional and behavioral factors that undermine reform efforts and reproduce investment cycles not only in Yugoslavia, but also in Hungary and other socialist economies.     

Monitoring and forecasting annual public deficit every month: the case of France

In this paper we forecast annual budget deficits using monthly information. Using French monthly data on central government revenues and expenditures, the method we propose consists of: (1) estimating monthly ARIMA models for all items of central government revenues and expenditures; (2) inferring the annual ARIMA models from the monthly models; (3) using the inferred annual ARIMA models to perform one-step-ahead forecasts for each item; (4) compounding the annual forecasts of all revenues and expenditures to obtain an annual budget deficit forecast. The major empirical benefit of this technique is that as soon as new monthly data become available, annual deficit forecasts are updated. This allows us to detect in advance possible slippages in central government finances. For years 2002–2004, forecasts obtained following the proposed approach are compared with a benchmark method and with official predictions published by the French government. An evaluation of their relative performance is provided.      

Die Erschließung vorhandener Wasserkraftpotenziale in Österreich im Spannungsfeld von Energiepolitik und ökologischen Schutzzielen

The intensified use of hydropower plays a substantial role in the Austrian energy sector. There are indeed plans to open up the remaining potentials, especially in the field of small-scale hydropower. However, hydropower creates multiple impacts. Although investments in hydropower are undisputed due to security of supply issues, climate change and dependency concerns, the technology is subject to some disadvantages. Hydropower plants are often seen as a blot on the landscape and a threat for the ecosystem, especially for fish and other water-dependent wildlife. Accordingly, hydropower plants are principally in conflict with nature conservation as for instance the European Water Framework Directive. With the help of a discrete choice model the trade-off between economic and climate-related advantages and the negative environmental side effects of new hydropower schemes was identified and quantified. While people value the economic (employment effects) and environmental (reduced air emissions) benefits related to the generation of electricity from hydroelectric power, they wish to be compensated for the loss of nature and landscape new hydropower plants are associated with. Moreover, confirmation of the “Not in my backyard” phenomenon was found, meaning that people generally prefer the construction of new hydropower stations, but not close to their homes.     

On the Measurement of Strength of Preference in Units of Money

We report an experimental study that aims to elicit monetary measures of strength of preference in choices involving pairs of risky prospects. Despite extensive testing to refine the instruments used, we find that these money measures are systematically biased upwards relative to subsequent binary choices. We discuss possible reasons for this bias and its broader implications.     

Low-cost pricing strategies in leisure markets

The practice of dynamic pricing typical of low-cost carriers is generally regarded as a form of price discrimination between “leisure” and “business” travellers on a single flight or route. The same may not be true across different routes because of the different incidence of business travellers. If price increases in the 15 days prior to departure are meant to discriminate business demand, leisure demand should account for earlier price variations. In the present study, we used a database containing the daily fare over the 3 months prior to each flight operated by easyJet during 2009. For each route, we defined the “leisure index” as the difference between the price rates of change during the 90 days and 15 days prior to departure. Overall, “business” routes had lower average prices per km, while “leisure” routes showed less dynamic price behaviour, with higher minimum and lower maximum prices per km.     

A Deliberative Case for Democracy in Firms

The increasing centrality of business firms in contemporary societies calls for a renewed attention to the democratization of these actors. This paper sheds new light on the possibility of democratizing business firms by bridging recent scholarship in two fields—deliberative democracy and business ethics. To date, deliberative democracy has largely neglected the role of business firms in democratic societies. While business ethics scholarship has given more attention to these issues, it has overlooked the possibility of deliberation within firms. As argued in the paper, a combination of reforms based on the ideas of workplace deliberation and business deliberation is necessary in order to promote the prospect of deliberation in different business contexts. The paper also discusses the importance of more democratic firms for deliberative democracy at large and, in particular, for the recent debate on deliberative systems. Finally, the paper suggests new areas of investigation to better understand the prospect of democratic deliberation in business firms.
