Abstract

Aims: The current study examined the association between insufficient major depressive disorder (MDD) care and healthcare resource use (HCRU) and costs among patients with prior myocardial infarction (MI) or stroke.

Methods: This was a retrospective study conducted using the MarketScan Claims Database (2010–2015). The date of the first MI/stroke diagnosis was defined as the cardiovascular disease (CVD) index date and the first date of a subsequent MDD diagnosis was the index MDD date. Adequacy of MDD care was assessed during the 90 days following the index MDD date (profiling period) using 2 measures: dosage adequacy (average fluoxetine equivalent dose of ≥20?mg/day for nonelderly and ≥10?mg/day for elderly patients) and duration adequacy (measured as the proportion of days covered of 80% or higher for all MDD drugs). Study outcomes included all-cause and CVD-related HCRU and costs which were determined from the end of the profiling period until the end of study follow-up. Propensity-score adjusted generalized linear models (GLMs) were used to compare patients receiving adequate versus inadequate MDD care in terms of study outcomes.

Results: Of 1,568 CVD patients who were treated for MDD, 937 (59.8%) were categorized as receiving inadequate MDD care. Results from the GLMs suggested that patients receiving inadequate MDD care had 14% more all-cause hospitalizations, 4% more all-cause outpatient visits, 17% more CVD-related outpatient visits, 13% more CVD-related emergency room (ER) visits, higher per patient per year CVD-related hospitalization costs ($21,485 vs. $17,756), higher all-cause outpatient costs ($2,820 vs. $2,055), and higher CVD-related outpatient costs ($520 vs. $434) compared to patients receiving adequate MDD care.

Limitations: Clinical information such as depression severity and frailty, which are potential predictors of adverse CVD outcomes, could not be ascertained using administrative claims data.

Conclusions: Among post-MI and post-stroke patients, inadequate MDD care was associated with a significantly higher economic burden.  相似文献

Abstract

Using a hand-collected dataset, we examine share trading activity over the period 1882–1920 for the North British and Mercantile Insurance Company, one of the largest UK companies of the time. Our main finding is that the steady flow of rentiers into the shareholding constituency of this company stymied share trading activity. Another important finding is that share trading still occurred during the closure of the stock exchange in 1914, but on a much-reduced scale. We also find that there was a substantial boom in share trading and in insurance stock prices after World War I.  相似文献

Income inequality has increased in China despite rapid economic growth. Income inequality could impinge on future development, leading to social tension or political instability. Our study investigates the short-run and long-run relationship between three important macroeconomic indicators—income inequality, economic growth and financial depth. We utilise a two-step procedure of ARDL bounds and Granger causality for the analysis. The bounds test indicates the presence of a cointegrating relationship between income inequality, financial depth and economic growth in the long run. In the second step, we utilise the Granger causality approach. Results show a bidirectional causality between financial depth-growth and a unidirectional causality between inequality-growth in the short run. In the long run, results reveal that growth and financial depth determine Gini. Our findings provide support for the inequality-widening effect due to economic growth and higher credit provided to the private sector. We find no evidence of inequality-narrowing or income-equalising effect in the long run for the period of study. It is possible that the government's inclusive growth policies which started less than a decade ago have not taken effect for us to capture the inverted U-shape income equalising effect significantly.  相似文献

This work analyses the firms' internationalisation strategies of importing intermediates and exporting output, and the potential rewards of these activities in terms of total factor productivity (TFP), as a proxy for marginal costs, and markups. It further deepens into the study of the relationship between internationalisation strategies and markups by disentangling whether it operates through affecting firms' marginal costs and/or firms' prices. The panel database employed in this paper is the Spanish Survey on Business Strategies (ESEE) for the period 2006–14. Results in the paper distinguish between SMEs and large firms and indicate that there is high persistence in the performance of these activities and in firms' TFP and markups. For SMEs, we obtain rewards from importing inputs as well as exporting output in terms of TFP and markups. For large firms, we obtain rewards in TFP from the importing activity and rewards in markups from the exporting activity. Finally, we find evidence that the effects of internationalisation strategies on markups are due to both a price channel and a marginal cost channel.  相似文献

Although brands offer different kinds of rewards through their loyalty programs, little is known about how they can impact consumer–brand relationships and brand attitude. How do loyalty program rewards influence the consumer–brand relationship? And which kinds of rewards establish or maintain closer relationships between consumers and brands than others? To answer these questions, the present research makes use of self-expansion theory (Aron & Aron, 1986) and two experiments that manipulate the extraordinary character of rewards offered to consumers. Our findings show that special rewards produce higher self-expansion than mundane rewards. Moreover, the positive effect of the rewards’ extraordinary character on brand evaluation, recommendation, and identification is sequentially and fully mediated by self-brand inclusion and self-expansion. Finally, we show that consumer satisfaction moderates the impact of special and mundane rewards on self-brand inclusion.  相似文献
