Socio-economic impact of epilepsy in Italy
No full text: The World Health Assembly recognizes the growing economic and societal burden of neurological disorders, a leading cause of disability and the second cause of mortality in the world. In this context we analysed the socio-economic impact of epilepsy in Italy with a specific focus on hospitalizations and costs related to disability pensions (DPs) and ordinary disability allowances. In the case of epilepsy, between 2009 and 2015 we observed an alarming increasing trend for DPs (+26%), indicating that substantial expenses must be supported throughout the patients' lifetimes by both the social security system and the National Health Service (NHS) on top of the impact on caregivers. We also analysed the hospital expenditure on epilepsy through the information available in the Hospital Discharge Cards between 2015 and 2018. Almost all admissions (76% ordinary hospitalizations, 24% day hospitals) were acute (95%), followed by rehabilitation (4%) and long-term care (1%). The cost of acute and ordinary hospitalizations was by far the highest in 2018, the last year of analysis. This large expense due to hospitalizations could be reduced through the implementation of different organizational and management approaches. Our recommendation is that the policy maker should consider the best approach to ensure an early diagnosis for patients and provide early access to drugs and/or surgery. Finally, the adoption of new innovative treatments should improve effectiveness and, at the same time, reduce the expense of the NHS, of the social system as a whole, with a tangible improvement in patients' quality of life
Direct and indirect costs of cluster headache : a prospective analysis in a tertiary level headache centre
Full text linkCluster headache (CH) is the most frequent trigemino-autonomic cephalgia. CH can manifest as episodic (ECH) or chronic cluster headache (CCH) causing significant burden of disease and requiring attack therapy and prophylactic treatment. The few data available on the economic burden of CH come from retrospective studies based on questionnaires, population surveys and medical insurance claims database. Although all these studies showed an important economic burden, they provided different estimates depending on variability of CH awareness and management, healthcare systems, available therapies and use of treatments according to different guidelines. This prospective study aimed to quantify the total direct and indirect cost of ECH and CCH over a cluster period, both for the patient and for the National Health System (NHS), using data from subjects who consecutively attended an Italian tertiary headache centre between January 1, 2018 and December 31, 2018. A total 108 patients (89 ECH, 19 CCH) were included. Mean attack frequency was 2.3 ± 1.4 per day. Mean total cost of a CH bout was €4398 per patient and total cost of CCH was 5.4 times higher than ECH (€13,350 vs. €2487, p < 0.001). Direct costs represented the 72.1% of total cost and were covered for the 94.8% by the NHS. The costs for any item of expense were higher for CCH than for ECH (p < 0.001). Mean indirect costs for a CH bout were €1226 per patient and were higher for CCH compared to ECH (€3.538 vs. €732), but the difference was not significant. Days with reduced productive capacity impacted for the 64.6% of the total indirect costs. The analysis of the impact CH on work showed that 27%% of patients felt that CH had limited their career, 40% had changed their work pattern, 20% had changed their place of employment and 10% had lost a job due to the disease. Our results provide a valuable estimate of the direct and indirect costs of ECH and CCH in the specific setting of a tertiary headache centre and confirm the high economic impact of CH on both the NHS and patients
The impact of Covid-19 vaccination on the Italian healthcare system: a scenario analysis
Full text linkBackground and Objective
During 2020, the only instruments for fighting against the pandemic peaks were lockdowns, physical distancing, closure of schools and non-essential businesses, and travel restrictions. The new vaccination strategy adopted in Italy in 2021 represented a new perspective for policymakers.
Objective
The aim of this study was to estimate the effects of the national immunisation strategy for coronavirus disease 2019 (COVID-19) in Italy on the national healthcare system.
Methods
An epidemiological scenario analysis was developed in order to simulate the impact of the COVID-19 pandemic on the Italian national healthcare system in 2021. Hospitalisations, intensive care unit (ICU) admissions and death rates were modelled based on 2020 data. Costs were estimated using hospital admissions from the Policlinico of Tor Vergata Hospital in Rome. Two scenarios were tested, one with vaccination and the second without.
Results
The roll-out of vaccinations to protect against COVID-19 was estimated to prevent 52,115 deaths in 2021, 45.2% less than what was expected in the absence of immunisation. Based on the assumptions underlying the two epidemiological scenarios, our model predicted an overall reduction of 2.4 million hospital admissions and 259,000 ICU admissions (74.9% and 71.3% less, respectively, than the world without vaccinations between June and December 2021). Overall, in Italy, the model estimated over €3.0 billion costs of hospitalisations due to COVID-19 in 2020. In 2021, vaccines prevented around 36% of the overall costs.
Conclusions
This is the first study highlighting the effect of vaccines on the Italian healthcare system in terms of avoided cases, hospitalisations and costs. Our results have the potential to inform policymakers and the general population on the benefits of vaccinations
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Socioeconomic differences in one-year survival after ischemic stroke: the effect of acute and post-acute care-pathways in a cohort study
Full text linkAbstract Background The reasons for socioeconomic inequity in stroke mortality are not well understood. The aim of this study was to explore the role of ischemic stroke care-pathways on the association between education level and one-year survival after hospital admission. Methods Hospitalizations for ischemic stroke during 2011/12 were selected from Lazio health data. Patients’ clinical history was defined by retrieving previous hospitalizations and drugs prescriptions. The association between education level and mortality after stroke was studied for acute and post-acute phases using multilevel logistic models (Odds Ratio (OR)). Different scenarios of quality care-pathways were identified considering hospital performance, access to rehabilitation and drug treatment post-discharge. The probability to survive to acute and post-acute phases according to education level and care-pathway scenarios was estimated for a “mean-severity” patient. One-year survival probability was calculated as the product of two probabilities. For each scenario, the 1-year survival probability ratio, university versus elementary education, and its Bootstrap Confidence Intervals (95 % BCI) were calculated. Results We identified 9,958 patients with ischemic stroke, 53.3 % with elementary education level and 3.2 % with university. The mortality was 14.9 % in acute phase and 14.3 % in post-acute phase among survived to the acute phase. The adjusted mortality in acute and post-acute phases decreased with an increase in educational level (OR = 0.90 p-trend < 0.001; OR = 0.85 p-trend < 0.001). For the best care-pathway, the one-year survival probability ratio was 1.06 (95 % BCI = 1.03–1.10), while it was 1.17 (95 % BCI = 1.09–1.25) for the worst. Conclusions Education level was inversely associated with mortality both in acute and post-acute phases. The care-pathway reduces but does not eliminate 1-year survival inequity
