Objectives: Complexities in the neuropathic-pain care pathway make the condition difficult to manage and difficult to capture in cost-effectiveness models. The aim of this study is to understand, through a systematic review of previous cost-effectiveness studies, some of the key strengths and limitations in data and modeling practices in neuropathic pain. Thus, the aim is to guide future research and practice to improve resource allocation decisions and encourage continued investment to find novel and effective treatments for patients with neuropathic pain.
Methods: The search strategy was designed to identify peer-reviewed cost-effectiveness evaluations of non-surgical, pharmaceutical therapies for neuropathic pain published since January 2000, accessing five key databases. All identified publications were reviewed and screened according to pre-defined eligibility criteria. Data extraction was designed to reflect key data challenges and approaches to modeling in neuropathic pain and based on published guidelines.
Results: The search strategy identified 20 cost-effectiveness analyses meeting the inclusion criteria, of which 14 had original model structures. Cost-effectiveness modeling in neuropathic pain is established and increasing across multiple jurisdictions; however, amongst these studies, there is substantial variation in modeling approach, and there are common limitations. Capturing the effect of treatments upon health outcomes, particularly health-related quality-of-life, is challenging, and the health effects of multiple lines of ineffective treatment, common for patients with neuropathic pain, have not been consistently or robustly modeled.
Conclusions: To improve future economic modeling in neuropathic pain, further research is suggested into the effect of multiple lines of treatment and treatment failure upon patient outcomes and subsequent treatment effectiveness; the impact of treatment-emergent adverse events upon patient outcomes; and consistent and appropriate pain measures to inform models. The authors further encourage transparent reporting of inputs used to inform cost-effectiveness models, with robust, comprehensive and clear uncertainty analysis and, where feasible, open-source modeling is encouraged. 相似文献
A large body of literature points to sharply growing income inequality over the past half century. The Piketty and Saez dataset that measures income distribution provides empirical support for this claim. Our article evaluates three prominent criticisms of this dataset as well as the responses of Piketty and Saez to these criticisms. One key argument against using their dataset is that Piketty and Saez do not control for income shifting by top income earners in response to the Tax Reform Act of 1986 (TRA86) and thus overstate income inequality. In evaluating this criticism we find that a segment of their dataset likely understates income inequality; this is just the opposite of what critics assert. This implies that the Piketty–Saez dataset is a valuable resource for income inequality research and that scholars can use it to build more refined, accurate and insightful measures of income inequality. 相似文献
This paper uses a large panel of data with up to 19 time-series observations for almost 150 countries to estimate models of arms imports. Qualitative evidence suggests a non-linear relationship. As income and military expenditure grow, the propensity to import first rises and then falls as a domestic arms industry develops. We face the difficulty that there is virtually no data on domestic arms procurement or production capability. We respond to this difficulty by adopting a random coefficient approach in order to identify any systematic influences on import propensity, through the impact of military expenditure, size of the armed forces or income on unobserved domestic production capability. While a clear non-linear pattern is apparent in the cross-section relationship, once one allows for parameter heterogeneity such a pattern is not apparent in the time-series. 相似文献
This article uses an insight from the French scholar Michel de Certeau to the effect that all stories are travel stories involving spatial transference and the theories of the Russian folklorist Vladimir Propp, as elaborated in his classic work Morphology of the Folktale, to argue all heroes are travelers of one sort or another. It suggests, that in addition to the fact that all heroes are travelers, all travelers are—broadly speaking—heroes and heroines. 相似文献

We exploit a unique sample to analyze how homophily (affinity for similar others) and social ties affect career outcomes in banking. We test if these factors increase the probability that the appointee to an executive board is an outsider without previous employment at the bank compared to being an insider. Homophily based on age and gender increase the chances of the outsider appointments. Similar educational backgrounds, in contrast, reduce the chance that the appointee is an outsider. Greater social ties also increase the probability of an outside appointment. Results from a duration model show that larger age differences shorten tenure significantly, whereas gender similarities barely affect tenure. Differences in educational backgrounds affect tenure differently across the banking sectors. Maintaining more contacts to the executive board reduces tenure. We also find weak evidence that social ties are associated with reduced profitability, consistent with cronyism in banking. 相似文献
This article presents new estimates of the Greek underground economy and explores the link between the underground economy and aggregate debt. We show that the Greek underground economy has been underestimated heavily and has been on a rising trend again since Greece adopted the Euro. We also present evidence that the size of the underground economy is positively related to the debt-to-GDP ratio, implying that fighting the underground economy is also conducive to financial and macroeconomic stability. Our results suggest that for our sample of 11 EMU member countries, the loss of the inflation tax as an economic policy instrument had drastic consequences. While the underground economy did not have a statistically significant impact on aggregate debt before the introduction of the Euro, it has pushed up the debt-to-GDP ratio in our sample since. 相似文献
The previous literature provides a highly ambiguous picture on the impact of trade and investment agreements on FDI. Most empirical studies ignore the actual content of BITs and RTAs, treating them as “black boxes”, despite the diversity of investment provisions constituting the essence of these agreements. We overcome this serious limitation by analyzing the impact of modalities on the admission of FDI and dispute settlement mechanisms in both RTAs and BITs on bilateral FDI flows between 1978 and 2004. We find that FDI reacts positively to RTAs only if they offer liberal admission rules. Dispute settlement provisions play a minor role. While RTAs without strong investment provisions may even discourage FDI, the reactions to BITs are less discriminate with foreign investors responding favourably to the mere existence of BITs. 相似文献
