L’accident vasculaire cérébral (AVC) est une maladie avec des taux de morbidité et de mortalité élevés, il est classé parmi les causes les plus fréquentes de décès et d’invalidité acquise dans le monde entier. Ainsi, évaluer son épidémiologie peut jouer un rôle crucial dans la réduction de son impact sur la population et la société. Le fardeau de l’AVC est attribué principalement aux pays en voie de développement, puisque les gens dans les pays développés ont une meilleure prise en charge et une sensibilisation accrue sur les symptômes et les facteurs de risque de l’AVC. Toutefois, dans les pays moins développés, où la population confronte l’énorme impact de l’urbanisation et de la mondialisation avec une augmentation accrue de la prévalence des facteurs de risque cardiovasculaire, l’incidence des AVC reste élevée. Peu de données épidémiologiques existent sur les AVC au Liban. Par conséquent, il était nécessaire de mener cette étude.Nous avons effectué une étude de cohorte multicentrique, prospective, basé sur l’incidence. Nous avons inclus 203 participants âgés de 18 ans et plus de 8 hôpitaux à Beyrouth entre Août 2015 et Août 2016 avec un diagnostic d’AVC confirmé. Les patients ont été suivis pendant une période d’un an (à l’admission à l’hôpital, à la sortie de l’hôpital et à 3, 6 et 12 mois par des visites à domicile).L’hypertension est le facteur de risque le plus puissant et le plus fréquent de l’AVC. Seulement 2,5 % des AVC ischémiques ont subi une thrombolyse. Le taux de mortalité cumulé était 13,3% à 1 mois et 21,2% à 1 an. Les complications et la gravité de l’AVC étaient des prédicteurs de décès à 1 mois et 1 an. Le niveau socio-économique bas, la dépendance dans les activités quotidiennes et les comorbidités étaient prédicteurs de mortalité supplémentaire à 1 an. La qualité de vie est relativement faible chez les patients atteints d’AVC et plus de 15 % d'entre eux étaient déprimés. Les principaux déterminants de la qualité de vie étaient: l’état fonctionnel, la dépendance dans les activités de la vie quotidienne, l’âge et la dépression. Les principaux déterminants de la dépression étaient l’état fonctionnel et la qualité de vie. Le coût direct hospitalier de tous les cas d’AVC était US$ 1,413,069 pour 2626 jours (538 US$ par jour à l’hôpital). Le coût moyen hospitalier par patient était US$ 6961±15, 663. Les AVC hémorragiques ont été les plus coûteux, l'accident ischémique transitoire étant le moins coûteux. Les prédicteurs de coûts étaient : la longueur du séjour hospitalier et dans l'unité de soins intensifs, le type d’AVC, la gravité de l’AVC, l'échelle de Rankin modifiée, les tiers payeurs, la chirurgie et les complications infectieuses.La prévention primaire est d’une importance primordiale dans la réduction de la charge de l’AVC. Les campagnes de sensibilisation sur les symptômes de cette maladie surtout pour la population hypertendue contribueront à limiter l’incidence de la maladie et donc à diminuer le fardeau financier et social élevé de l’AVC (le coût de la maladie et la qualité de vie). La mise en place d’unités spécialisées pour les AVC et l’augmentation du pourcentage de patients thrombolysés peuvent réduire la mortalité à court terme et les incapacités de longue durée et donc améliorer la qualité de vie des patients atteints d’AVC. / Stroke is a disease with high morbidity and mortality rates, classified among the most common causes of death and acquired disability worldwide. Thus, assessing its epidemiology may play a crucial role in reducing its impact on the population and the society. Stroke late burden is attributable to developing countries mainly, as people in developed countries have a better access to optimal care and an increased awareness on stroke symptoms and risk factors. However, in less developed countries, where population confronts the huge impact of urbanization and globalization with a great increase in the prevalence of cardiovascular risk factors, the incidence of stroke remains high. Lebanon is lacking data on the epidemiology of stroke. Therefore, it was necessary to conduct this study and highlight some features of the disease epidemiology.We carried out a multicenter prospective incidence-based cohort study. We included 203 participants aged 18 years and more from 8 hospitals in Beirut between August 2015 and August 2016 with confirmed diagnosis of stroke. Patients were followed for a 1-year period (at hospital admission and discharge, and by home visits at 3, 6 and 12 months).Hypertension was the most powerful and prevalent risk factor for stroke. Only 2.5% of ischemic strokes received thrombolytic therapy. Cumulative mortality rates were 13.3% at 1-month and 21.2% at 1-year. Stroke severity and complications were predictors of death at 1-month and 1-year. Low socioeconomic status, dependency in daily living activities, and co-morbidities were additional 1-year mortality predictors. The quality of life was relatively low in stroke patients and more than 15% of them were depressed. The main determinants of quality of life were functional status, dependency in daily living activities, age, and depression. The main determinants of depression were functional status and quality of life. The direct in-hospital cost for all cases was US$1,413,069 for 2626 days (US$538 per in-hospital day). The average in-hospital cost per stroke patient was US$6961±15,663. Hemorrhagic strokes were the most costly, transient ischemic attack being the least costly. Cost drivers were hospital and intensive care unit length of stay, type of stroke, stroke severity, modified Rankin Scale, third party payer, surgery and infectious complications.Primary prevention is of paramount importance in reducing the burden of stroke. Awareness campaigns on stroke symptoms especially among hypertensive population would help limit the incidence of the disease and therefore decrease the high financial and social burden of stroke (cost of illness and quality of life). The establishment of stroke units and increasing the percentage of thrombolysis may reduce short-term mortality and long term disabilities and therefore improve the quality of life of stroke patients.

Background: Following passage of the Affordable Care Act in 2010, 30-day hospital readmissions have come under greater scrutiny. Excess readmissions for certain medical conditions and procedures now result in penalizations on all Medicare reimbursements. We examined the risk factors, outcomes, and costs of 30-day readmissions after colorectal surgery (CRS). Methods: The University HealthSystem Consortium database was queried for adults (≥ 18 years) who underwent colorectal resection for cancer, diverticular disease, inflammatory bowel disease, or benign tumors between January 2008 and December 2011. Our outcomes of interest were readmission within 30-days of the patient’s index discharge, hospital readmission outcomes, and total direct hospital costs. Results: A total of 70,484 patients survived the index hospitalization after CRS during the years under study, 13.7% (9,632) of which were readmitted within 30 days of discharge. The strongest independent predictors of readmission were: LOS ≥4 days (OR 1.44; 95% CI 1.32-1.57), stoma (OR 1.53; 95% CI 1.45-1.61), and discharge to skilled nursing (OR 1.63; 95% CI 1.49-1.76) or rehabilitation facility (OR 2.93; 95% CI 2.54-3.40). Of those readmitted, half occurred within 7 days of the index admission, 13% required ICU care, 6% had a reoperation, and 2% died during the readmission stay. The median combined total direct hospital cost was over twice as high ($26,917 v. $13,817) for readmitted than for nonreadmitted patients. Conclusions: Readmissions following colorectal resection occur frequently and incur a significant financial burden on the healthcare system. Future studies aimed at targeted interventions for high-risk patients may reduce readmissions and curb escalating healthcare costs.

Qualitative research has suggested that spousal carers of someone with dementia differ in terms of whether they perceive their relationship with that person as continuous with the premorbid relationship or as radically different, and that a perception of continuity may be associated with more person-centered care and the experience of fewer of the negative emotions associated with caring. The aim of the study was to develop and evaluate a quantitative measure of the extent to which spousal carers perceive the relationship to be continuous. METHODS: An initial pool of 42 questionnaire items was generated on the basis of the qualitative research about relationship continuity. These were completed by 51 spousal carers and item analysis was used to reduce the pool to 23 items. The retained items, comprising five subscales, were then administered to a second sample of 84 spousal carers, and the questionnaire's reliability, discriminative power, and validity were evaluated. RESULTS: The questionnaire showed good reliability: Cronbach's alpha for the full scale was 0.947, and test-retest reliability was 0.932. Ferguson's delta was 0.987, indicating good discriminative power. Evidence of construct validity was provided by predicted patterns of subscale correlations with the Closeness and Conflict Scale and the Marwit-Meuser Caregiver Grief Inventory. CONCLUSION: Initial psychometric evaluation of the measure was encouraging. The measure provides a quantitative means of investigating ideas from qualitative research about the role of relationship continuity in influencing how spousal carers provide care and how they react emotionally to their caring role.

Introdução O Transtorno de Déficit de Atenção/hiperatividade (TDAH) tem sido muito estudado, mas informações econômicas referentes ao seu tratamento com o metilfenidato de liberação imediata (MFD-LI) ainda necessitam ser exploradas. Grande parte da população mundial, principalmente aqueles que vivem em países em desenvolvimento, utiliza essa formulação como principal escolha para o tratamento do TDAH. Esses países, por sua condição financeira, necessitam informações de análises econômicas para administrar de forma eficiente os recursos públicos destinados aos setores da saúde. Objetivos Avaliar a eficácia do MFD-LI através de estudos com tempo superior a 12 semanas, e realizar uma análise econômica para o tratamento do TDAH com MFD-LI para crianças e adolescentes brasileiros. Método O estudo foi planejado em cinco etapas: 1) estimativa de custo do não tratamento do TDAH para o Brasil, e estimativa de economia com tratamento com MFD-LI; 2) revisão sistemática da literatura nas principais bases de dados internacionais onde se buscaram estudos abertos com tratamento do TDAH com MFD-LI por tempo igual ou superior a 12 semanas; também foram feitas metanálises e uma metaregressão 3) estudo naturalístico para obterem-se dados de uma amostra brasileira referentes a probabilidades de uso e sucesso com tratamento com MFD-LI por 12 semanas, e estimar os utilities desses indivíduos; 4) painel Delphi com especialistas em TDAH no Brasil; 5) estudo de custo-efetividade para o tratamento do TDAH com MFD-LI no Brasil, utilizando um Modelo de Markov. A perspectiva adotada será a do sistema público de saúde brasileiro como pagador. Resultados Os resultados principais encontrados para cada uma das etapas foram: 1) a estimativa de custos anuais com o TDAH não tratado no Brasil foi de R$ 1.594 bilhões/ano, e da quantia que poderia ser economizada se tratado, R$ 1 bilhão/ano. 2) na revisão sistemática da literatura, de 4.498 resumos, sete foram incluídos para compor a metanálise. O tempo de tratamento variou entre 13 e 104 semanas. O efeito agregado para desatenção e hiperatividade medida pelos pais, respectivamente, foi 0.96 (95%CI 0.60 - 1.32) e 1.12 (95%CI 0.85 - 1.39), e pelos professores 0.98 (95%CI 0.09 - 1.86) e 1.25 (95% CI 0.7 - 1.81). A metaregressão não mostrou associação entre as variáveis idade, qualidade do artigo e tempo de tratamento com heterogeneidade. 3) no estudo naturalístico, de 171 pacientes avaliados, 73 forneceram informações para o baseline, e 56 para a 12a semana de tratamento com MFD-LI. Os utilities para um paciente com TDAH não tratado (baseline) foram 0.69 (crianças) e 0.66 (adolescentes), e estimaram-se ganhos entre 0.09 a 0.10 utilities/mês, se tratados adequadamente. 4) no painel Delphi, de 26 especialistas, 14 responderam o questionário online, e foi estimado que a probabilidade dos pacientes não tratados se manterem sintomáticos na 12a semana seria de 91%, e 9% a probabilidade de melhora espontânea; 5) no estudo de custo-efetividade, para o caso base, estimou-se que o Incremental Cost Effectiveness Ratio (ICER) seja I$9,103/QALY (Quality Adjusted Life Years) para crianças e I$11,883/QALY para adolescentes em um horizonte temporal de 06 anos. Para os cenários mais desfavoráveis, os ICERS mais elevados foram I$95,164/QALY para 50% de sucesso com o tratamento, e I$15,000/QALY para 70% de adesão em um horizonte temporal de 06 anos. Conclusões O MFD-LI é um tratamento eficaz para crianças e adolescentes, por um período superior a 12 semanas. Entretanto, o Brasil pode estar aumentando os custos referentes à saúde por não estar fornecendo um tratamento eficaz e economicamente acessível para o TDAH. O tratamento mostrou ser uma opção custo-efetiva para crianças e adolescentes brasileiros, mesmo em cenários desfavoráveis para o tratamento. / Introduction Attention-Deficit/Hyperactivity Disorder (ADHD) is a well-known psychiatric disorder, but some economical aspects of the treatment with Methylphenidate Immediate-release (MPH -IR) still need to be explored. A large number of people around the world, most living in Low-Middle Income Countries (LMIC), use this formulation as the first choice for ADHD treatment. These countries, due to their financial condition, need information from health economic analyzes to efficiently manage the public resources allocated to the health sector. Objective To study the efficacy of MPH-IR reviewing studies conducted for more than 12 weeks long, and to perform an economic analysis for the treatment of ADHD with MPH-IR for Brazilian children. Method The study was planned in a five stages process: 1) to estimate the cost of untreated ADHD for Brazil, and to estimate the savings if MPH-IR were adequately provided; 2) systematic review of the literature to identify papers published where young patients with ADHD were treated with MPH-IR for more than 12 weeks, and to perform a meta-analysis and a meta-regression; 3) to conduct a naturalistic study with a Brazilian sample to collect the probabilities of use and success with the MPH-IR treatment for 12 weeks, and to estimate the utilities; 4) to perform a Delphi panel with ADHD Brazilian experts; 5) to conduct a cost-effectiveness analysis for the treatment of ADHD with MPH-IR in Brazil, using a Markov model. The perspective is the one of the Brazilian public health system as the payer. Results The main findings for each step were: 1) the estimated annual expenditures with untreated ADHD in Brazil were R$1.594billon/year, and the estimated amount that could be saved was R$1billion/year; 2) in the systematic review, from 4,498 abstracts, 7 studies were selected. The length of treatment ranged from 13 to 104 weeks. The aggregate effects for inattention and hyperactivity, according to parents evaluations were respectively 0.96 (95%CI 0.60 - 1.32) and 1.12 (95%CI 0.85 - 1.39), and for teachers 0.98 (95%CI 0.09 - 1.86) e 1.25 (95% CI 0.7 - 1.81). There was no evidence of association between heterogeneity and the variables, age, paper quality and length of treatment; 3) in the naturalistic study, from 171 patients assessed, 73 provided information in the baseline, and 56 in the 12th week of MPH-IR treatment. Utilities for an untreated ADHD patient (baseline) were 0.69 (children) and 0.66 (adolescents), and it was estimated a gain ranging from 0.09 to 0.10 utilities/month if subjects were properly treated; 4) in the Delphi Panel, 26 experts were addressed and 14 filled in the online questionnaire. It was estimated the probability of untreated patients to remain symptomatic on the 12th week to be 91%, and the probability of spontaneous improvement, 9%; 5) in the cost-effectiveness analysis, for the base case, it was estimated an Incremental Cost Effectiveness Ratio (ICER) of I$9,103/QALY (Quality Adjusted Life Years) for children and I$11,883/QALY for adolescents, in a time horizon of 6 years. The worst case scenarios were also tested, and the highest ICER were I$95,164/QALY when patient reached 50 % of success with the treatment, and I$15,000/QALY if only 70% of use was observed in a time horizon of 6 years. Conclusions MPH-IR is an efficacious treatment for ADHD children and adolescents for periods longer than 12 weeks. However, Brazil may be probably wasting money due to not provide an efficient and affordable treatment for ADHD such as the MPH-IR. The treatment proved to be cost-effective for children and adolescents living in Brazil, even when the worst case scenarios were tested.

Conclusions MPH-IR is an efficacious treatment for ADHD children and adolescents for periods longer than 12 weeks. However, Brazil may be probably wasting money due to not provide an efficient and affordable treatment for ADHD such as the MPH-IR. The treatment proved to be cost-effective for children and adolescents living in Brazil, even when the worst case scenarios were tested.

Health economists, national decision-makers and global health specialists have been interested in calculating the cost of a disease for many years. Only more recently they started to generate more comprehensive frameworks and tools to estimate the full range of healthcare related costs of illness in a user’s perspective in resource-poor settings. There is now an ongoing trend to guide health policy, and identify the most effective ways to achieve universal health coverage. The user fee exemptions health financing schemes, which grounded the tuberculosis control strategy, have been designed to improve access to essential care for ill individuals with a low capacity to pay. After decades of functioning and substantial progress in tuberculosis detection rate and treatment success, this thesis analyses the extent of the coverage (financial and social protection) of two disease control programs in West Africa. Learning from the concept of the medical poverty trap (Whitehead, Dahlgren, et Evans 2001) and available framework related to the economic consequences of illness (McIntyre et al. 2006), a conceptual framework and a data collection tool have been developed to incorporate the direct, indirect and intangible costs and consequences of illness incurred by chronic patients. In several ways, we have sought to provide baseline for comprehensive analysis and standardized methodology to allow comparison across settings, and to contribute to the development of evidence-based knowledge.<p><p>To begin, filling a knowledge gap (Russell 2004), we have performed microeconomic research on the households’ costs-and-consequences-of-tuberculosis in Burkina Faso and Benin. The two case studies have been conducted both in rural and urban resource-poor settings between 2007 and 2009. This thesis provides new empirical findings on the remaining financial, social and ‘healthcare delivery related organizational’ barriers to access diagnosis and treatment services that are delivered free-of-charge to the population. The direct costs associated with illness incurred by the tuberculosis pulmonary smear-positive patients have constituted a severe economic burden for these households living in permanent budget constraints. Most of these people have spent catastrophic health expenditure to cure tuberculosis and, at the same time, have faced income loss caused by the care-seeking. To cope with the substantial direct and indirect costs of tuberculosis, the patients have shipped their families in impoverishing strategies to mobilize funds for health such as depleting savings, being indebted and even selling livestock and property. Damaging asset portfolios of the disease-affected households on the long run, the coping strategies result in a public health threat. In resource-poor settings, the lack of financial protection for health may impose inability to meet basic needs such as the rights to education, housing, food, social capital and access to primary healthcare. Special feature of our work lies in the breakdown of the information gathered. We have been able to demonstrate significant differences in the volume and nature of the amounts spent across the successive stages of the care-seeking pathway. Notably, pre-diagnosis spending has been proved critical both in the rural and urban contexts. Moreover, disaggregated cost data across income quintiles have highlighted inequities in relation to the direct costs and to the risk of incurring catastrophic health expenditure because of tuberculosis. As part of the case studies, the tuberculosis control strategies have failed to protect the most vulnerable care users from delayed diagnosis and treatment, from important spending even during treatment – including significant medical costs, and from hidden costs that might have been exacerbated by poor health systems. To such devastating situations, the tuberculosis patients have had to endure other difficulties; we mean intangible costs such as pain and suffering including stigmatization and social exclusion as a result of being ill or attending tuberculosis care facilities. The analysis of all the social and economic consequences for tuberculosis-affected households over the entire care-seeking pathway has been identified as an essential element of future cost-of-illness evaluations, as well as the need to conduct benefit incidence assessment to measure equity.<p><p>This work has allowed identifying a series of policy weaknesses related to the three dimensions of the universal health coverage for tuberculosis (healthcare services, population and financial protection coverage). The findings have highlighted a gap between the standard costs foreseen by the national programs and the costs in real life. This has suggested that the current strategies lack of patient-centered care, context-oriented approaches and systemic vision resulting in a quality issue in healthcare delivery system (e.g. hidden healthcare related costs). Besides, various adverse effects on households have been raised as potential consequences of illness; such as illness poverty trap, social stigma, possible exclusion from services and participation, and overburdened individuals. These effects have disclosed the lack of social protection at the country level and call for the inclusion of tuberculosis patients in national social schemes. A last policy gap refers to the lack of financial protection and remaining inequities with regards to catastrophic health expenditure still occurring under use fee exemptions strategies. Thereby, one year before 2015 – the deadline set for the Millennium Development Goals – it is a matter of priority for Benin and Burkina Faso and many other countries to tackle adverse effects of the remaining social, economic and health policy and system related barriers to tuberculosis control. These factors have led us to emphasize the need for countries to develop sustainable knowledge. <p><p>National decision-makers urgently need to document the failures and bottlenecks. Drawing on the findings, we have considered different ways to strengthen local capacity and generate bottom-up decision-making. To get there, we have shaped a decision framework intended to produce local evidence on the root causes of the lack of policy responsiveness, synthesize available evidence, develop data-driven policies, and translate them into actions.<p><p>Beyond this, we have demonstrated that controlling tuberculosis was much more complex than providing free services. The socio-economic context in which people affected by this disease live cannot be dissociated from health policy. The implications of microeconomic research on the households’ costs and responses to tuberculosis may have a larger scope than informing implementation and adaptation of national disease-specific strategies. They can be of great interest to support the definition of guiding principles for further research on social protection schemes, and to produce evidence-based targets and indicators for the reduction and the monitoring of economic burden of illness. In this thesis, we have build on prevailing debates in the field and formulated different assumptions and proposals to inform the WHO Global Strategy and Targets for Tuberculosis Prevention, Care and Control After 2015. For us, to reflect poor populations’ needs and experiences, global stakeholders should endorse bottom-up and systemic policy-making approaches towards sustainable people-centered health systems.<p><p>The findings of the thesis and the various global and national challenges that have emerged from case studies are crucial as the problems we have seen for tuberculosis in West Africa are not limited to this illness, and far outweigh the geographical context of developing countries.<p><p><p>Keywords: Catastrophic health expenditure, Coping strategies, Cost-of-illness studies, Direct, indirect and intangible costs, Evidence-based Public health, Financial and Social protection for health, Health Economics, Health Policy and Systems, Informed Decision-making, Knowledge translation, People-centered policy-making, Systemic approach, Universal Health Coverage<p> / Doctorat en Sciences de la santé publique / info:eu-repo/semantics/nonPublished
