Consumer willingness to pay for a hypothetical Zika vaccine in Brazil and the implications

ABSTRACT : Background: Zika virus is a newly emerging infection, associated with increasingly large outbreaks especially in tropical countries such as Brazil. A future Zika vaccine can contribute to decreasing the number of cases and associated complications. Information about consumers’ willingness to pay (WTP) for a hypothetical Zika vaccine can help price setting discussions in the future in Brazil, starting with the private market. Methods: A cross-sectional study conducted among residents of Minas Gerais, Brazil, regarding their WTP for a hypothetical Zika Vaccine. The mean effective protection was 80%, with the possibility of some local and systemic side- effects. Results: 517 people were interviewed. However, 28 would not be vaccinated even if the vaccine was free. Most of the resultant interviewees (489) were female (58.2%), had completed high school (49.7%), were employed (71.2%), had private health insurance (52.7%), and did not have Zika (96.9%). The median individual maximum WTP for this hypothetical Zika vaccine (one dose) was US$31.34 (BRL100.00). Conclusion: Such discussions regarding WTP can contribute to decision-making about prices once a Zika vaccine becomes available in Brazil alongside other ongoing programs to control the virus

Funding and service organization to achieve universal health coverage for medicines : an economic evaluation of the best investment and services organization for the Brazilian scenario

Background: There are many health benefits since 31 years after the foundation of the National Health Service (NHS) in Brazil, especially the increase in life expectancy. However, family-income inequalities, insufficient funding, and suboptimal private sector–public sector collaboration are still areas for improvement. The efforts of Brazil to achieve universal health coverage (UHC) for medicines have resulted in increased public financing of medicines and their availability, reducing avoidable hospitalization and mortality. However, lack of access to medicines still remains. Due to historical reasons, pharmaceutical service organization in developing countries may have important differences from high-income countries. In some cases, developing countries finance and promote medicine access by using the public infrastructure of health care/medical units as dispensing sites and cover all costs of medicines dispensed. In contrast, many high-income countries use private community pharmacies and cover the costs of medicines dispensed plus a fee, which includes all logistic costs. In this study, we will undertake an economic evaluation to understand the funding needs of the Brazilian NHS to reduce inequalities in access to medicines through adopting a pharmaceutical service organization similar to that seen in many high-income countries with hiring/accrediting private pharmacies. Methods: We performed an economic evaluation of a model to provide access to medicines within public funds based on a decision tree model with two alternative scenarios public pharmacies (NHS, state-owned facilities) versus private pharmacies (NHS, agreements). The analysis assumed the perspective of the NHS. We identified the types of resources consumed, the amount, and costs in both scenarios. We also performed a budget impact forecast to estimate the incremental funding required to reduce inequalities in access to essential medicines in Brazil. Findings: The model without rebates for medicines estimated an incremental cost of US$3.1 billion in purchasing power parity (PPP) but with an increase in the average availability of medicines from 65$1.3 billion per year (30%). The impact of incremental funding is related to medicine access improvement of 25% in the second year when paying by dispensing fee. The estimate of the incremental budget in five years would be US$4.8 billion PPP. We have yet to explore the potential reduction in hospital and outpatient costs, as well as in lawsuits, with increased availability with the yearly expenses for these at US$9 billion and US$1.4 billion PPP respectively in 2017. Interpretation: The results of the economic evaluation demonstrate potential savings for the NHS and society. Achieving UHC for medicines reduces household expenses with health costs, health litigation, outpatient care, hospitalization, and mortality. An optimal private sector–public sector collaboration model with private community pharmacy accreditation is economically dominant with a feasible medicine price negotiation. The results show the potential to improve access to medicines by 25% for all income classes. This is most beneficial to the poorest families, whose medicines account for 76% of their total health expenses, with potential savings of lives and public resources

Pharmaceutical services in the primary health care of the Brazilian Unified Health System:: advances and challenges

This study is a synthesis of the main results of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), Evaluation Component of the Basic Pharmaceutical Services. Based on the critical narrative of the elements of Brazil’s pharmaceutical policies, we discuss aspects related to the structure of the pharmaceutical services, the medicines’ sanitary state, human resources, access to medicines, rational use and management. Despite the advances that reflect the commitment of the group of actors involved, the results of the Survey indicate challenges, such as equitable access to medicines, the structuring of pharmaceutical services, the improvement of logistics and administration, and the implementation of actions directed to pharmaceutical care in the health unitsTrata-se de uma síntese dos principais resultados da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos, componente de Avaliação dos Serviços de Assistência Farmacêutica Básica. Com base em narrativa crítica dos elementos das políticas farmacêuticas no Brasil, discutem-se aspectos relacionados à estrutura dos serviços farmacêuticos, situação sanitária dos medicamentos, recursos humanos, acesso a medicamentos, uso racional e gestão. Apesar dos avanços que refletem o empenho do conjunto de atores implicados, os resultados da Pesquisa apontam desafios, como o acesso equitativo dos medicamentos, a estruturação dos serviços farmacêuticos, o aprimoramento da logística e da gestão e a implantação de ações voltadas ao cuidado farmacêutico nas unidades de saúd

Effectiveness of maintenance immunosuppression therapies in a matched-pair analysis cohort of 16 years of renal transplant in the Brazilian national health system

Maintenance of patients with renal transplant typically involves two or more drugs to prevent rejection and prolong graft survival. The calcineurin inhibitors (CNI) are the most commonly recommended medicines in combinations with others. While immunosuppressive treatment regimens are well established, there is insufficient long-term effectiveness data to help guide future management decisions. The study analyzes the effectiveness of treatment regimens containing CNI after renal transplantation during 16 years follow-up with real-world data from the Brazilian National Health System (SUS). This was a retrospective study with SUS patients after renal transplantion. Patients were propensity score-matched (1:1) by sex, age, type and year of transplantation. Kaplan-Meier was used to estimate the cumulative probabilities of survival. A Cox proportional hazard model was used to evaluate factors associated with progression to graft loss. 2,318 patients were included. Multivariable analysis, adjusted for diabetes mellitus and race / color, showed a greater risk of graft loss for patients using tacrolimus plus mycophenolate compared to patients treated with cyclosporine plus azathioprine. In conclusion, this Brazilian real-world study, with a long follow-up period using the matched analysis for relevant clinical features, and the representativeness of the sample, demonstrated improved long-term effectiveness for therapeutic regimens containing cyclosporine plus azathioprine. Consequently, we recommend that protocols and clinical guidelines for renal transplantation should consider cyclosporine plus azathioprine regimen as a potential first line option along with others

Real-world evaluation of the impact of statin intensity on adherence and persistence to therapy : a Scottish population-based study

Aim: To assess associations between statin intensity and adherence, persistence and discontinuation of statin therapy in Scotland. Method: Retrospective cohort study, using linked electronic health records covering a period from January 2009 to December 2016. The study cohort included adult patients (≥18 years) newly initiating statins within Greater Glasgow and Clyde, Scotland. Study outcomes comprised adherence, discontinuation and persistence to treatment, stratified by three exposure groups (high, moderate and low intensity). Discontinuation and persistence were calculated using the refill-gap and anniversary methods, respectively. Proportion of days covered (PDC) was used as a proxy for adherence. Kaplan-Meier survival curves and Cox proportional hazard models were used to evaluate discontinuation, and associations between adherence/persistence and statin intensity were assessed using logistic regression. Results: A total of 73 716 patients with a mean age of 61.4 ± 12.6 years were included; the majority (88.3%) received moderate intensity statins. Discontinuation rates differed between intensity levels, with high-intensity patients less likely to discontinue treatment compared to those on moderate intensity (prior cardiovascular disease [CVD]: HR 0.43 [95% CI 0.34-0.55]; no prior CVD: 0.80 [0.74-0.86]). Persistence declined over time, and high-intensity patients had the highest persistence rates. Overall, 52.6% of patients were adherent to treatment (PDC ≥ 80%), but adherence was considerably higher among high-intensity patients (63.7%). Conclusion: High-intensity statins were associated with better persistence and adherence to treatment, but overall long-term persistence and adherence remain a challenge, particularly among patients without prior CVD. This needs addressing

Indicadores relacionados ao uso racional de medicamentos e seus fatores associados

OBJETIVO: Avaliar indicadores relacionados ao uso racional de medicamentos e seus fatores associados em unidades básicas de saúde. MÉTODOS: Estudo transversal realizado em amostra representativa de municípios do Brasil incluídos na Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015. Os dados foram coletados por meio de entrevista com usuários, profissionais dispensadores de medicamentos e prescritores; e descritos por meio de indicadores de prescrição, dispensação e de serviços de saúde. Realizou-se análise da associação entre características dos recursos humanos dos serviços farmacêuticos e indicadores de dispensação. RESULTADOS: Em nível nacional, o número médio de medicamentos prescritos foi de 2,4. A proporção de usuários com prescrição de antibiótico foi de 5,8%, 74,8% dos usuários receberam orientações sobre medicamentos na farmácia e para 45,1% usuários todos os medicamentos prescritos eram da relação nacional de medicamentos essenciais. Todos os indicadores apresentaram variações estatisticamente significantes entre as regiões do Brasil. Os dispensadores que relataram a presença de farmacêutico na unidade com carga horária igual ou superior a 40 horas semanais apresentaram 1,82 mais chance de transmitir orientações sobre o modo de usar dos medicamentos no processo de dispensação. CONCLUSÕES: A análise de indicadores de prescrição, dispensação e de serviços de saúde nas unidades básicas de saúde mostrou proporção insatisfatória de prescrição de medicamentos essenciais e limitações na identificação correta do medicamento, orientação aos pacientes sobre medicamentos e de disponibilidade de protocolos terapêuticos nos serviços de saúdeOBJECTIVE: To evaluate indicators related to the rational use of medicines and its associated factors in Basic Health Units. METHOD: This is a cross-sectional study carried out in a representative sample of Brazilian cities included in the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). The data were collected by interviews with users, medicine dispensing professionals, and prescribers; and described by prescription, dispensing, and health services indicators. We analyzed the association between human resources characteristics of pharmaceutical services and dispensing indicators. RESULTS: At national level, the average number of medicines prescribed was 2.4. Among the users, 5.8% had antibiotic prescription, 74.8% received guidance on how to use the medicines at the pharmacy and, for 45.1% of users, all prescribed medicines were from the national list of essential medicines. All the indicators presented statistically significant differences between the regions of Brazil. The dispensing professionals that reported the presence of a pharmacist in the unit with a working load of 40 hours or more per week presented 1.82 more chance of transmitting information on the way of using the medicines in the dispensing process. CONCLUSION: The analysis of prescription, dispensing, and health services indicators in the basic health units showed an unsatisfactory proportion of essential medicines prescription and limitations in the correct identification of the medicine, orientation to the patients on medicines, and availability of therapeutic protocols in the health service

Public spending on drugs for the treatment of osteoporosis in post-menopause

OBJECTIVE: To analyze expenditure on treatment for postmenopausal osteoporosis and associated factors on mean per capita expenditure. METHODS: A probabilistic-deterministic linkage between the database of Authorizations for Highly Complex Procedures and the mortality information system was constructed, resulting in a historical cohort of patients using high-cost medications for the treatment of postmenopausal osteoporosis, between 2000-2006. Mean monthly spending on medicines was stratified by age group and described according to demographic and clinical characteristics and the type of drug used. A linear regression model was used to assess the impact of demographic and clinical characteristics on per capita mean monthly expenditure on medicines. RESULTS: We identified 72,265 women who received drugs for the treatment of postmenopausal osteoporosis. The average monthly expenditure per capita in the first year of treatment was $54.02 (sd$ 86.72). The population was predominantly composed of women aged 60-69 years old, who had started treatment in 2000, resident in the Southeast of Brazil, who had previously suffered osteoporotic fractures, and Alendronate sodium was the drug most commonly used at baseline. For most of the patients, the same active ingredient remained in use throughout the treatment period. During the program, 6,429 deaths were identified among participants. More than a third of women remained in treatment for up to 12 months. Raloxifen and calcitonin were the therapeutic alternatives with the greatest impact on the average monthly expenditure on medicine using alendronate sodium as a reference standard. CONCLUSIONS: Due to the high impact of the type of drug used on expenditure on medication, it is recommended that criteria for prescribing and dispensing be established by prioritizing those with lower costs and greater effectiveness in order to optimize the process of pharmaceutical care and provide the population with a greater number of pharmaceutical units.OBJETIVO: Analisar os gastos com medicamentos para o tratamento da osteoporose na pós-menopausa e os fatores associados ao gasto médio per capita .

O gasto médio mensal com medicamentos foi estratificado por faixas etárias e descrito de acordo com as características demográficas, clínicas e tipo de medicamento utilizado. Foi utilizado modelo de regressão linear para avaliar o impacto de características demográficas e clínicas sobre o gasto médio mensal per capita com os medicamentos. RESULTADOS: Foram identificadas 72.265 mulheres que receberam medicamentos para o tratamento da osteoporose na pós-menopausa. O gasto médio mensal per capita no primeiro ano de tratamento foi de R$90,00 (dp R$ 144,49). A maioria das mulheres tinha de 60 a 69 anos de idade, iniciaram tratamento em 2000, eram residentes na região Sudeste, tinham fraturas osteoporóticas prévias e o alendronato de sódio foi o medicamento mais utilizado no início do tratamento. A maioria das pacientes permaneceu em uso do mesmo princípio ativo durante o tratamento. Foram identificados 6.429 óbitos entre as participantes. Mais de um terço das mulheres permaneceram no programa por até 12 meses. Raloxifeno e calcitonina sintética foram as alternativas com maior impacto sobre o gasto médio mensal com medicamentos, tendo como padrão de referência o alendronato de sódio. CONCLUSÕES: Dado o alto impacto do tipo de medicamento utilizado no gasto com medicação, recomenda-se estabelecer critérios para prescrição e dispensação, com prioridade para aqueles com menores custos e maior efetividade. Isso pode otimizar o processo de assistência farmacêutica e a provisão de maior número de unidades farmacêuticas à população.OBJETIVO: Analizar los gastos con medicamentos para el tratamiento de la osteoporosis en la post-menopausia y los factores asociados al gasto promedio per cápita.

Raloxifeno y calcitonina sintética fueron las alternativas con mayor impacto sobre el gasto promedio mensual con medicamentos, teniendo como patrón de referencia el alendronato de sodio. CONCLUSIONES: Dado el alto impacto del tipo de medicamento utilizado en el gasto por parte del SUS, se recomienda establecer criterios para prescripción y dispensación, priorizando aquellos con menores costos y mayor efectividad. Esto puede optimizar el proceso de asistencia farmacéutica y la provisión de mayor número de unidades farmacéuticas para la población

Efficacy of Mobile Apps to Support the Care of Patients With Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background- Diabetes Mellitus (DM) is a chronic disease that is considered a global public health problem. Education and self-monitoring by diabetic patients help to optimize and make possible a satisfactory metabolic control enabling improved management and reduced morbidity and mortality. The global growth in the use of mobile phones makes them a powerful platform to help provide tailored health, delivered conveniently to patients through health applications (apps). Objective- Evaluate the efficacy of mobile apps through a systematic review and meta-analysis to assist diabetes mellitus patients in treatment. Methods- We conducted searches in the electronic databases MEDLINE (Pubmed), CENTRAL/ Cochrane Register of Controlled Trials and LILACS, manual search in references of publications included, systematic reviews, specialized journals and gray literature. We considered eligible randomized controlled trials (RCTs) conducted after 2008 with participants of all ages, diabetes mellitus patients and users of apps to help manage the disease. The meta-analysis of glycated hemoglobin (HbA1c) was performed in Review Manager Software 5.3. Results- The literature search identified 1236 publications. From these, 13 studies were included that evaluated 1263 patients. In six RCTs, there were a statistical significant reduction (P < 0.05) of HbA1c at the end of studies in the intervention group. The HbA1c data were evaluated by meta-analysis with the following results (MD = - .44; CI: - .59, - .29; P < .10; I² = 32%).The evaluation favored the treatment in patients who used apps without significant heterogeneity. Conclusions - The use of apps by diabetic patients could help improve the control of HbA1c. In addition, the apps seem to strengthen the perception of self-care contributing better information and health education to patients. Patients also become more self-confident to deal with their diabetes, mainly, by reducing fear of not knowing how to deal with potential hypoglycemic episodes that may occur

Economic and epidemiological impact of dengue illness over 16 years from a public health system perspective in Brazil to inform future health policies including the adoption of a dengue vaccine

Introduction: Dengue is a serious global health problem endemic in Brazil. Consequently, our aim was to measure the costs and disease burden of symptomatic dengue infections in Brazil from the perspective of the Brazilian Public Health System (SUS) between 2000 and 2015 using Brazilian public health system databases. Specific age group incidence estimates were used to calculate the disability-adjusted life years (DALYs) to gain a better understanding of the disease burden. Areas covered: SUS spent almost USD159 million and USD10 million to treat dengue and severe dengue, respectively, between 2000-2015. This is principally hospitalization costs with the majority of patients self-treated at home with minor symptoms. The average notification rate for dengue was 273 per 100,000 inhabitants and 3 per 100,000 for severe dengue, with annual DALYs estimates ranging between 72.35 to 6,824.45 during the 16 years. Expert commentary: The epidemiological and morbidity burden associated with dengue is substantial in Brazil, with costs affected by the fact that most patients self-treat at home with these costs not included in SUS. The Brazilian government urgently needs to proactively evaluate the real costs and clinical benefits of any potential dengue vaccination program by the National Immunization Program to guide future decision making
