On-demand mobile hypertension training for primary health care workers in Nigeria: a pilot study.

BACKGROUND: Only one out of every ten Nigerian adults with hypertension has their blood pressure controlled. Health worker training is essential to improve hypertension diagnosis and treatment. In-person training has limitations that mobile, on-demand training might address. This pilot study evaluated a self-paced, case-based, mobile-optimized online training to diagnose and manage hypertension for Nigerian health workers. METHODS: Twelve hypertension training modules were developed, based on World Health Organization and Nigerian guidelines. After review by local academic and government partners, the course was piloted by Nigerian health workers at government-owned primary health centers. Primary care physician, nurse, and community health worker participants completed the course on their own smartphones. Before and after the course, hypertension knowledge was evaluated with multiple-choice questions. Learners provided feedback by responding to questions on a Likert scale. RESULTS: Out of 748 users who sampled the course, 574 enrolled, of whom 431 (75%) completed the course. The average pre-test score of completers was 65.4%, which increased to 78.2% on the post-test (P < 0.001, paired t-test). Health workers who were not part of existing hypertension control programs had lower pre-test scores and larger score gains. Most participants (96.1%) agreed that the training was applicable to their work, and nearly all (99.8%) agreed that they enjoyed the training. CONCLUSIONS: An on-demand mobile digital hypertension training increases knowledge of hypertension management among Nigerian health workers. If offered at scale, such courses can be a tool to build health workforce capacity through initial and refresher training on current clinical guidelines in hypertension and other chronic diseases in Nigeria as well as other countries.

Cost of Cardiovascular Disease Event and Cardiovascular Disease Treatment-Related Complication Hospitalizations in the United States.

BACKGROUND: Cardiovascular disease (CVD) is among the costliest conditions in the United States, and cost-effectiveness analyses can be used to assess economic impact and prioritize CVD treatments. We aimed to develop standardized, nationally representative CVD events and selected possible CVD treatment-related complication hospitalization costs for use in cost-effectiveness analyses. METHODS: Nationally representative costs were derived using publicly available inpatient hospital discharge data from the 2012-2018 National Inpatient Sample. Events were identified using the principal International Classification of Diseases, Ninth Revision and International Classification of Diseases, Tenth Revision codes. Facility charges were converted to costs using charge-to-cost ratios, and total costs were estimated by applying a published professional fee ratio. All costs are reported in 2021 US dollars. Mean costs were estimated for events overall and stratified by age, sex, and survival status at discharge. Annual costs to the US health care system were estimated by multiplying the mean annual number of events by the mean total cost per discharge. RESULTS: The annual mean number of hospital discharges among CVD events was the highest for heart failure (1 087 000 per year) and cerebrovascular disease (800 600 per year). The mean cost per hospital discharge was the highest for peripheral vascular disease ($33 700 [95% CI, $33 300-$34 000]) and ventricular tachycardia/ventricular fibrillation ($32 500 [95% CI, $32 100-$32 900]). Hospitalizations contributing the most to annual US health care costs were heart failure ($19 500 [95% CI, $19 300-$19 800] million) and acute myocardial infarction ($18 300, [95% CI, $18 200-$18 500] million). Acute kidney injury was the most frequent possible treatment complication (515 000 per year), and bradycardia had the highest mean hospitalization costs ($17 400 [95% CI, $17 200-$17 500]). CONCLUSIONS: The hospitalization cost estimates and statistical code reported in the current study have the potential to increase transparency and comparability of cost-effectiveness analyses for CVD in the United States.

Cost analysis of the WHO-HEARTS program for hypertension control and CVD prevention in primary health facilities in Ethiopia.

Background: In 2020, Ethiopia launched the Ethiopia Hypertension Control Initiative (EHCI) program to improve hypertension care using the approach described in the WHO HEARTS technical package. Objective: To estimate the costs of implementing the HEARTS program for hypertension control and cardiovascular disease (CVD) prevention in the primary care setting in Ethiopia for adult primary care users in the catchment area of five examined facilities. Study design: This study entails a program cost analysis using cross-sectional primary and secondary data. Methods: Micro-costing facility surveys were used to assess activity costs related to training, counselling, screening, lab diagnosis, medications, monitoring, and start-up costs at five selected health facilities. Cost data were obtained from primary and secondary sources, and expert opinion. Annual costs from the health system perspective were estimated using the Excel-based HEARTS costing tool under two intervention scenarios - hypertension-only control and a CVD risk management program, which addresses diabetes and hypercholesterolemia in addition to hypertension. Results: The estimated cost per adult primary care user was USD 5.3 for hypertension control and USD 19.3 for integrated CVD risk management. The estimated medication cost per person treated for hypertension was USD 9.0, whereas treating diabetes and high cholesterol would cost USD 15.4 and USD 15.3 per person treated, respectively. Medications were the major cost driver, accounting for 37% of the total cost in the hypertension control program. In the CVD risk management scenario, the proportions of medication and lab diagnostics of total costs were 18% and 64%, respectively. Conclusions: The results from this study can inform planning and budgeting for HEARTS scale-up to prevent CVD across Ethiopia.

[Monitoring and evaluation platform for HEARTS in the Americas: improving population-based hypertension control programs in primary health carePlataforma de monitoramento e avaliação do programa HEARTS nas Américas: melhoria dos programas de controle da hipertensão de base populacional na atenção primária à saúde]. / Plataforma de monitoreo y evaluación para HEARTS en las Américas: hacia la mejora de los programas de control de la hipertensión a nivel poblacional en la atención primaria de salud.

HEARTS in the Americas is the Pan American Health Organization flagship program to accelerate the reduction of the cardiovascular disease (CVD) burden by improving hypertension control and CVD secondary prevention in primary health care. A monitoring and evaluation (M&E) platform is needed for program implementation, benchmarking, and informing policy-makers. This paper describes the conceptual bases of the HEARTS M&E platform including software design principles, contextualization of data collection modules, data structure, reporting, and visualization. The District Health Information Software 2 (DHIS2) web-based platform was chosen to implement aggregate data entry of CVD outcome, process, and structural risk factor indicators. In addition, PowerBI was chosen for data visualization and dashboarding for the analysis of performance and trends above the health care facility level. The development of this new information platform was focused on primary health care facility data entry, timely data reporting, visualizations, and ultimately active use of data to drive decision-making for equitable program implementation and improved quality of care. Additionally, lessons learnt and programmatic considerations were assessed through the experience of the M&E software development. Building political will and support is essential to developing and deploying a flexible platform in multiple countries which is contextually specific to the needs of various stakeholders and levels of the health care system. The HEARTS M&E platform supports program implementation and reveals structural and managerial limitations and care gaps. The HEARTS M&E platform will be central to monitoring and driving further population-level improvements in CVD and other noncommunicable disease-related health.

AddREssing Social Determinants TO pRevent hypErtension (The RESTORE Network): Overview of the Health Equity Research Network to Prevent Hypertension.

BACKGROUND: The American Heart Association funded a Health Equity Research Network on the prevention of hypertension, the RESTORE Network, as part of its commitment to achieving health equity in all communities. This article provides an overview of the RESTORE Network. METHODS: The RESTORE Network includes five independent, randomized trials testing approaches to implement non-pharmacological interventions that have been proven to lower blood pressure (BP). The trials are community-based, taking place in churches in rural Alabama, mobile health units in Michigan, barbershops in New York, community health centers in Maryland, and food deserts in Massachusetts. Each trial employs a hybrid effectiveness-implementation research design to test scalable and sustainable strategies that mitigate social determinants of health (SDOH) that contribute to hypertension in Black communities. The primary outcome in each trial is change in systolic BP. The RESTORE Network Coordinating Center has five cores: BP measurement, statistics, intervention, community engagement, and training that support the trials. Standardized protocols, data elements and analysis plans were adopted in each trial to facilitate cross-trial comparisons of the implementation strategies, and application of a standard costing instrument for health economic evaluations, scale up, and policy analysis. Herein, we discuss future RESTORE Network research plans and policy outreach activities designed to advance health equity by preventing hypertension. CONCLUSIONS: The RESTORE Network was designed to promote health equity in the US by testing effective and sustainable implementation strategies focused on addressing SDOH to prevent hypertension among Black adults.

Effectiveness and Cost-Effectiveness of Team-Based Care for Hypertension: A Meta-Analysis and Simulation Study.

BACKGROUND: Team-based care (TBC), a team of ≥2 healthcare professionals working collaboratively toward a shared clinical goal, is a recommended strategy to manage blood pressure (BP). However, the most effective and cost-effective TBC strategy is unknown. METHODS: A meta-analysis of clinical trials in US adults (aged ≥20 years) with uncontrolled hypertension (≥140/90 mm Hg) was performed to estimate the systolic BP reduction for TBC strategies versus usual care at 12 months. TBC strategies were stratified by the inclusion of a nonphysician team member who could titrate antihypertensive medications. The validated BP Control Model-Cardiovascular Disease Policy Model was used to project the expected BP reductions out to 10 years and simulate cardiovascular disease events, direct healthcare costs, quality-adjusted life years, and cost-effectiveness of TBC with physician and nonphysician titration. RESULTS: Among 19 studies comprising 5993 participants, the 12-month systolic BP change versus usual care was -5.0 (95% CI, -7.9 to -2.2) mm Hg for TBC with physician titration and -10.5 (-16.2 to -4.8) mm Hg for TBC with nonphysician titration. Relative to usual care at 10 years, TBC with nonphysician titration was estimated to cost $95 (95% uncertainty interval, -$563 to $664) more per patient and gain 0.022 (0.003-0.042) quality-adjusted life years, costing $4400/quality-adjusted life year gained. TBC with physician titration was estimated to cost more and gain fewer quality-adjusted life years than TBC with nonphysician titration. CONCLUSIONS: TBC with nonphysician titration yields superior hypertension outcomes compared with other strategies and is a cost-effective way to reduce hypertension-related morbidity and mortality in the United States.

Cost-effectiveness analysis of initial treatment with single-pill combination antihypertensive medications.

Hypertension guidelines recommend initiating treatment with single pill combination (SPC) antihypertensive medications, but SPCs are used by only one-third of treated hypertensive US adults. This analysis estimated the cost-effectiveness of initial treatment with SPC dual antihypertensive medications compared with usual care monotherapy in hypertensive US adults.The validated BP Control Model-Cardiovascular Disease (CVD) Policy Model simulated initial SPC dual therapy (two half-standard doses in a single pill) compared with initial usual care monotherapy (half-standard dose when baseline systolic BP < 20 mmHg above goal and one standard dose when ≥20 mmHg above goal). Secondary analyses examined equivalent dose monotherapy (one standard dose) and equivalent dose dual therapy as separate pills (two half-standard doses). The primary outcomes were direct healthcare costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) over 10 years from a US healthcare sector perspective.At 10 years, initial dual drug SPC was projected to yield 0.028 (95%UI 0.008 to 0.051) more QALYs at no greater cost ($73, 95%UI -$1 983 to $1 629) than usual care monotherapy. In secondary analysis, SPC dual therapy was cost-effective vs. equivalent dose monotherapy (ICER $8 000/QALY gained) and equivalent dose dual therapy as separate pills (ICER $57 000/QALY gained). At average drug prices, initiating antihypertensive treatment with SPC dual therapy is more effective at no greater cost than usual care initial monotherapy and has the potential to improve BP control rates and reduce the burden of CVD in the US.

The Health and Economic Impact of Using a Sugar Sweetened Beverage Tax to Fund Fruit and Vegetable Subsidies in New York City: A Modeling Study.

Low fruit and vegetable (FV) intake and high sugar-sweetened beverage (SSB) consumption are independently associated with an increased risk of developing cardiovascular disease (CVD). Many people in New York City (NYC) have low FV intake and high SSB consumption, partly due to high cost of fresh FVs and low cost of and easy access to SSBs. A potential implementation of an SSB tax and an FV subsidy program could result in substantial public health and economic benefits. We used a validated microsimulation model for predicting CVD events to estimate the health impact and cost-effectiveness of SSB taxes, FV subsidies, and funding FV subsidies with an SSB tax in NYC. Population demographics and health profiles were estimated using data from the NYC Health and Nutrition Examination Survey. Policy effects and price elasticity were derived from recent meta-analyses. We found that funding FV subsidies with an SSB tax was projected to be the most cost-effective policy from the healthcare sector perspective. From the societal perspective, the most cost-effective policy was SSB taxes. All policy scenarios could prevent more CVD events and save more healthcare costs among men compared to women, and among Black vs. White adults. Public health practitioners and policymakers may want to consider adopting this combination of policy actions, while weighing feasibility considerations and other unintended consequences.

Financial implications of protocol-based hypertension treatment: an insight into medication costs in public and private health sectors in India.

Hypertension is a major public health challenge in low- and middle-income countries (LMICs) and calls for large-scale effective hypertension control programs. Adoption of drug and dose-specific treatment protocols recommended by the World Health Organization-HEARTS Initiative is key for hypertension control programs in LMICs. We estimated the annual medication cost per patient using three such protocols (protocol-1 and protocol-2 with Amlodipine, Telmisartan, using add-on doses and different drug orders, adding Chlorthalidone; protocol-3 with a single-pill combination (SPC) of Amlodipine/Telmisartan with dose up-titration, and addition of Chlorthalidone, if required) in India. The medication cost was simulated with different hypertension control assumptions for each protocol and calculated based on prices in the public and private sectors in India. The estimated annual medication cost per patient for protocol-1 and protocol-2 was $33.88-58.44 and $51.57-68.83 for protocol-3 in the private sector. The medication cost was lower in the generic stores ($5.78-9.57 for protocol-1 and protocol-2, and $7.35-9.89 for protocol-3). The medication cost for patients was the lowest ($2.05-3.89 for protocol-1 and protocol-2, and $2.94-3.98 for protocol-3) in the public sector. At less than $4 per patient per annum, scaling up a hypertension control program with specific treatment protocols is a potentially cost-effective public health intervention. Expanding low-cost generic retail networks would extend affordability in the private sector. The cost of treatment with SPC is comparable with non-SPC protocols and can be adopted in a public health program considering the advantage of simplified logistics, reduced pill burden, improved treatment adherence, and blood pressure control.

Availability of Hypertension and Diabetes Mellitus Care Services at Subdistrict Level in Bangladesh.

BACKGROUND: In Bangladesh, the rapid rise of noncommunicable diseases (NCDs) has become a significant public health concern. This study assesses the readiness of hypertension (HTN)- and diabetes mellitus-related services at primary health-care facilities in Northeast Bangladesh. METHODOLOGY: A cross-sectional survey using a semi-structured interview was conducted between April 2021 and May 2021 among 51 public primary health-care facility staff (upazila health complexes [UHCs]). The NCD-specific service readiness was assessed using an adapted questionnaire from the WHO manual of Service Availability and Readiness Assessment and included four domains: guidelines and staff, basic equipment, diagnostic facility, and essential medicine. For each domain, the mean readiness index score was calculated. Facilities with a readiness score of above 70% were considered to be ready. RESULTS: The diagnostic capacity of the UHCs ranged from 0% to 88.9%, the availability of essential medicine and basic equipment varied between 15.4%-69.2% and 36.4%-100%, respectively, whereas the score in availability of basic amenities was between 57.1% and 100%. The score for the protocol drugs used to manage HTN was 52.9%, whereas for diabetes, it was 88.2%. The average general service readiness score for the facilities was 59.1%. Overall 17.6% of the facilities were assessed to be ready. CONCLUSION: Currently, primary health-care facilities are not ready to implement the national guidelines for diagnosing and treating diabetes and HTN due to shortages of medications, staff, and diagnostic materials.

Building the health-economic case for scaling up the WHO-HEARTS hypertension control package in low- and middle-income countries.

Generally, hypertension control programs are cost-effective, including in low- and middle-income countries, but country governments and civil society are not likely to support hypertension control programs unless value is demonstrated in terms of public health benefits, budget impact, and value-for-investment for the individual country context. The World Health Organization (WHO) and the Pan American Health Organization (PAHO) established a standard, simplified Global HEARTS approach to hypertension control, including preferred antihypertensive medicines and blood pressure measurement devices. The objective of this study is to report on health economic studies of HEARTS hypertension control package cost (especially medication costs), cost-effectiveness, and budget impact and describe mathematical models designed to translate hypertension control program data into the optimal approach to hypertension care service delivery and financing, especially in low- and middle-income countries. Early results suggest that HEARTS hypertension control interventions are either cost-saving or cost-effective, that the HEARTS package is affordable at between US$ 18-44 per person treated per year, and that antihypertensive medicines could be priced low enough to reach a global standard of an average

En general, los programas de control de la hipertensión son costo-eficaces, incluso en los países de ingresos bajos y medios. Aun así, es poco probable que los gobiernos nacionales y la sociedad civil apoyen los programas de control de la hipertensión a menos que se demuestre su valor en términos de beneficios para la salud pública, impacto presupuestario y valor de la inversión para el contexto individual del país. La Organización Mundial de la Salud (OMS) y la Organización Panamericana de la Salud (OPS) implementaron la iniciativa HEARTS, un enfoque mundial estandarizado y simplificado para el control de la hipertensión, que incluye los medicamentos antihipertensivos y los dispositivos de medición de la presión arterial de preferencia. El objetivo de este estudio es informar sobre los estudios en el ámbito de la economía de la salud relativos al costo de las medidas de control de la hipertensión previstas en HEARTS (especialmente, de los medicamentos), la costo-efectividad y el impacto presupuestario, así como describir los modelos matemáticos diseñados para traducir los datos de este programa en un enfoque óptimo para la prestación y el financiamiento de los servicios de atención de la hipertensión, especialmente en países de ingresos medianos y bajos. Los primeros resultados indican que las intervenciones de HEARTS para el control de la hipertensión son de bajo costo o costo-eficaces, que el conjunto de medidas HEARTS es asequible, a un precio que oscila entre US$ 18 y US$ 44 al año por paciente tratado, y que los medicamentos antihipertensivos podrían tener un precio lo suficientemente bajo como para alcanzar un estándar medio mundial de

Geralmente, os programas de controle de hipertensão são custo-efetivos, inclusive em países de baixa e média renda, mas os governos dos países e a sociedade civil provavelmente não apoiarão tais programas a menos que demonstrem valor em termos de benefícios à saúde pública, impacto orçamentário e retorno sobre o investimento no contexto individual do país. A Organização Mundial da Saúde (OMS) e a Organização Pan-Americana da Saúde (OPAS) criaram a Global HEARTS, uma abordagem padrão e simplificada ao controle da hipertensão arterial, que inclui medicamentos anti-hipertensivos preferidos e dispositivos para aferição da pressão arterial preferidos. O objetivo deste estudo é relatar os estudos de economia em saúde que analisaram o custo (especialmente custos de medicamentos), custo-benefício e impacto orçamentário do pacote HEARTS para controle da hipertensão e descrever modelos matemáticos elaborados para traduzir os dados do programa de controle de hipertensão em uma abordagem ideal para a prestação e financiamento de serviços de atenção às pessoas com hipertensão, especialmente em países de baixa e média renda. Os primeiros resultados sugerem que as intervenções HEARTS para controle da hipertensão são de baixo custo ou custo-efetivas, que o pacote HEARTS é acessível (custando de US$ 18 a 44 por pessoa tratada por ano) e que o preço dos medicamentos anti-hipertensivos poderia ser baixo o suficiente para atingir uma média global de

Assessing costs of a hypertension program in primary care: evidence from the HEARTS program in Mexico.

Objective: In 2021, Mexico launched the HEARTS program to improve the prevention and control of cardiovascular disease (CVD) risk factors in 20 primary care facilities in the states of Chiapas and Yucatán. This study projects the annual cost of program implementation and discusses budgetary implications for scaling up the program. Methods: We obtained district-level data on treatment protocols, medication costs, and other resources required to prevent and treat CVD. We used the HEARTS Costing Tool to estimate total and per-patient costs. A "partial implementation" scenario calculated the costs of implementing HEARTS if existing pharmacological treatment protocols are left in place. The second scenario, "full implementation," examined costs if programs use HEARTS pharmacological protocol. Results: Respectively in the partial and full implementation scenarios, total annual costs to implement and operate HEARTS were $260 023 ($32.1 per patient/year) and $255 046 ($31.5 per patient/year) in Chiapas, and $1 000 059 ($41.3 per patient/year) and $1 013 835 ($43.3 per patient/year) in Yucatán. In Chiapas, adopting HEARTS standardized treatment protocols resulted in a 9.7 % reduction in annual medication expenditures relative to maintaining status-quo treatment approaches. In Yucatán, adoption was $12 875 more expensive, in part because HEARTS hypertension treatment regimens were more intensive than status quo regimens. Conclusion: HEARTS in the Americas offers a standardized strategy to treating and controlling CVD risk factors. In Mexico, approaches that may lead to improved program affordability include adoption of the recommended HEARTS treatment protocols with preferred medications and task shifting of services from physicians to nurses and other providers.

Monitoring and evaluation platform for HEARTS in the Americas: improving population-based hypertension control programs in primary health care

[ABSTRACT]. HEARTS in the Americas is the Pan American Health Organization flagship program to accelerate the reduction of the cardiovascular disease (CVD) burden by improving hypertension control and CVD secondary prevention in primary health care. A monitoring and evaluation (M&E) platform is needed for program implementation, benchmarking, and informing policy-makers. This paper describes the conceptual bases of the HEARTS M&E platform including software design principles, contextualization of data collection modules, data structure, reporting, and visualization. The District Health Information Software 2 (DHIS2) web-based platform was chosen to implement aggregate data entry of CVD outcome, process, and structural risk factor indicators. In addition, PowerBI was chosen for data visualization and dashboarding for the analysis of performance and trends above the health care facility level. The development of this new information platform was focused on primary health care facility data entry, timely data reporting, visualizations, and ultimately active use of data to drive decision-making for equitable program implementation and improved quality of care. Additionally, lessons learnt and programmatic considerations were assessed through the experience of the M&E software development. Building political will and support is essential to developing and deploying a flexible platform in multiple countries which is contextually specific to the needs of various stakeholders and levels of the health care system. The HEARTS M&E platform supports program implementation and reveals structural and managerial limitations and care gaps. The HEARTS M&E platform will be central to monitoring and driving further population-level improvements in CVD and other noncommunicable disease-related health.

[RESUMEN]. HEARTS en las Américas es el programa insignia de la Organización Panamericana de la Salud para acelerar la reducción de la carga de enfermedades cardiovasculares (ECV) mediante la mejora del control de la hipertensión y la prevención secundaria de las ECV en la atención primaria de salud. Es necesaria una plataforma de monitoreo y evaluación (M&E) para ejecutar el programa, establecer puntos de referencia y notificar a los responsables de las políticas. En este artículo se describen las bases conceptuales de la plataforma HEARTS M&E, como los principios de diseño del software, la contextualización de los módulos de recopilación de datos, la estructura de los datos, la presentación de información y la visualización. Se escogió la plataforma web District Health Information Software 2 (DHIS2) para ejecutar el ingreso de los datos agregados de los indicadores de resultados, procesos y factores de riesgo estructurales de las ECV. Además, se eligió PowerBI para la visualización de datos y la elaboración del panel de control para el análisis del desempeño y las tendencias más allá del nivel de los centros de atención médica. El desarrollo de esta nueva plataforma de información se centró en el ingreso de datos de los centros de atención primaria de salud, la presentación oportuna de datos, las visualizaciones y, en última instancia, el uso activo de los datos para impulsar la toma de decisiones en la ejecución equitativa del programa y la mejora de calidad de la atención. Además, se evaluaron las enseñanzas extraídas y las consideraciones programáticas con la experiencia del desarrollo de software de M&E. Lograr el apoyo y la voluntad política es esencial para desarrollar y poner en marcha una plataforma flexible en múltiples países que sea contextualmente específica según las necesidades de las diversas partes interesadas y los niveles del sistema de atención de la salud. La plataforma HEARTS M&E brinda apoyo para la ejecución del programa y muestra las limitaciones estructurales y gerenciales, así como las brechas en la atención. Esta plataforma será fundamental para monitorear e impulsar nuevas mejoras a nivel de la población en lo que respecta a las ECV y otras enfermedades no transmisibles relacionadas.

[RESUMO]. A iniciativa HEARTS nas Américas é o principal programa da Organização Pan-Americana da Saúde para acelerar a redução da carga de doenças cardiovasculares (DCV) por meio do melhoramento do controle da hipertensão e da prevenção secundária de DCV na atenção primária à saúde. Uma plataforma de monitoramento e avaliação (M&E, na sigla em inglês) é necessária para a implementação do programa, para fazer a avaliação comparativa e para informar os formuladores de políticas. Este documento descreve as bases conceituais da plataforma de M&E do HEARTS, incluindo princípios de design de software, contextualização dos módulos de coleta de dados, estrutura de dados, relatórios e visualização. A plataforma baseada na web do District Health Information Software 2 (DHIS2) foi escolhida para implementar a inserção de dados agregados de indicadores de fatores de risco estruturais, processos e desfechos de DCV. Além disso, o PowerBI foi escolhido para a visualização de dados e para fazer o dashboard da análise de desempenho e tendências para além do nível da unidade de saúde. O desenvolvimento desta nova plataforma de informações teve como foco a inserção de dados da unidade de atenção primária à saúde, a notificação oportuna de dados, visualizações e o uso ativo dos dados para orientar a tomada de decisões para a implementação equitativa do programa e a melhoria da qualidade do atendimento. Além disso, as lições aprendidas e as considerações programáticas foram avaliadas por meio da experiência do desenvolvimento do software de M&E. Fomentar vontade política e apoio é essencial para desenvolver e implantar uma plataforma flexível em vários países, que seja contextualmente específica para as necessidades das diferentes partes interessadas e níveis do sistema de saúde. A plataforma de M&E do HEARTS ampara a implementação do programa e revela limitações estruturais e gerenciais, bem como lacunas na atenção à saúde. A plataforma de M&E do HEARTS será central para monitorar e impulsionar mais melhorias no nível populacional em DCV e outras doenças não transmissíveis.

[RESUMEN]. Objetivo. En el año 2021, México puso en marcha el programa HEARTS para mejorar la prevención y el con- trol de los factores de riesgo de las enfermedades cardiovasculares en 20 centros de atención primaria en los estados de Chiapas y Yucatán. En este estudio se estima el costo anual de la ejecución del programa y se abordan las implicaciones presupuestarias para su ampliación. Métodos. Se obtuvieron datos a nivel de distrito sobre los protocolos de tratamiento, los costos de los medica- mentos y otros recursos necesarios para prevenir y tratar las enfermedades cardiovasculares. Se empleó la herramienta HEARTS para el cálculo de costos con el fin de estimar los costos totales y por paciente. En una situación de “implementación parcial”, se calcularon los costos de ejecutar HEARTS si se mantienen los pro- tocolos de tratamiento farmacológico existentes. En un segundo escenario de “implementación completa”, se examinaron los costos de los programas que emplean el protocolo farmacológico de HEARTS. Resultados. En los escenarios de implementación parcial y total, respectivamente, los costos anuales totales para implementar y poner en marcha el paquete de medidas HEARTS fueron de US$ 260 023 (US$ 32,1 por paciente al año) y US$ 255 046 (US$ 31,5 por paciente al año) en Chiapas, y US$ 1 000 059 (US$ 41,3 por paciente al año) y US$ 1 013 835 (US$ 43,3 por paciente al año) en Yucatán. En Chiapas, la adopción de los protocolos de tratamiento estandarizados de HEARTS supuso una reducción de 9,7% en los gastos anuales de medicamentos en comparación con el mantenimiento de los enfoques de tratamiento ya establecidos. En Yucatán, la adopción fue US$ 12 875 más cara, en parte porque los esquemas de tratamiento para la hiper- tensión que se proponen en HEARTS fueron más intensivos que los esquemas ya establecidos. Conclusiones. El programa HEARTS en la Región de las Américas ofrece una estrategia estandarizada para tratar y controlar los factores de riesgo de las enfermedades cardiovasculares. En México, los enfoques que pueden conducir a una mayor asequibilidad del programa incluyen la adopción de los protocolos de tratamiento recomendados de HEARTS con medicamentos de preferencia y la distribución de tareas de los servicios para que pasen del personal médico al personal de enfermería y otros prestadores de atención de salud.

[RESUMO]. Objetivo. Em 2021, o México lançou o programa HEARTS para melhorar a prevenção e o controle dos fatores de risco de doenças cardiovasculares (DCV) em 20 unidades básicas de saúde nos estados de Chiapas e Yucatán. Este estudo projeta o custo anual de implementação do programa e discute as implicações orça- mentárias para sua expansão. Métodos. Foram obtidos dados de nível distrital sobre protocolos de tratamento, custos de medicamentos e outros recursos necessários para prevenir e tratar a DCV. A ferramenta de cálculo de custos do HEARTS foi usada para estimar os custos totais e por paciente. Um cenário de “implementação parcial” calculou os cus- tos de implementação do HEARTS se os protocolos de farmacoterapia existentes forem mantidos em vigor. O segundo cenário, “implementação plena”, examinou os custos se os programas utilizassem o protocolo de farmacoterapia do HEARTS. Resultados. Respectivamente nos cenários de implementação parcial e plena, os custos anuais totais para implementar e operar o HEARTS foram de US$ 260 023 (US$ 32,1 por paciente/ano) e US$ 255 046 (US$ 31,5 por paciente/ano) em Chiapas, e $1 000 059 (US$ 41,3 por paciente/ano) e US$ 1 013 835 (US$ 43,30 por paciente/ano) em Yucatán. Em Chiapas, a adoção de protocolos de tratamento padronizados do HEARTS resultou em uma redução de 9,7% nos gastos anuais com medicamentos em relação à manutenção das condutas atuais (status quo). Em Yucatán, a adoção foi US$ 12 875 mais cara, em parte porque os regimes de tratamento de hipertensão do HEARTS eram mais intensivos do que os regimes atuais. Conclusão. A HEARTS nas Américas oferece uma estratégia padronizada para tratar e controlar os fatores de risco de DCV. No México, abordagens que podem levar a uma melhor acessibilidade do programa incluem a adoção dos protocolos de tratamento recomendados do HEARTS com medicamentos preferidos e a realo- cação de tarefas de médicos para enfermeiros e outros profissionais.

An efficient approach for optimizing the cost-effective individualized treatment rule using conditional random forest.

Evidence from observational studies has become increasingly important for supporting healthcare policy making via cost-effectiveness analyses. Similar as in comparative effectiveness studies, health economic evaluations that consider subject-level heterogeneity produce individualized treatment rules that are often more cost-effective than one-size-fits-all treatment. Thus, it is of great interest to develop statistical tools for learning such a cost-effective individualized treatment rule under the causal inference framework that allows proper handling of potential confounding and can be applied to both trials and observational studies. In this paper, we use the concept of net-monetary-benefit to assess the trade-off between health benefits and related costs. We estimate cost-effective individualized treatment rule as a function of patients' characteristics that, when implemented, optimizes the allocation of limited healthcare resources by maximizing health gains while minimizing treatment-related costs. We employ the conditional random forest approach and identify the optimal cost-effective individualized treatment rule using net-monetary-benefit-based classification algorithms, where two partitioned estimators are proposed for the subject-specific weights to effectively incorporate information from censored individuals. We conduct simulation studies to evaluate the performance of our proposals. We apply our top-performing algorithm to the NIH-funded Systolic Blood Pressure Intervention Trial to illustrate the cost-effectiveness gains of assigning customized intensive blood pressure therapy.

Building the health-economic case for scaling up the WHO-HEARTS hypertension control package in low- and middle-income countries

[ABSTRACT]. Generally, hypertension control programs are cost-effective, including in low- and middle-income countries, but country governments and civil society are not likely to support hypertension control programs unless value is demonstrated in terms of public health benefits, budget impact, and value-for-investment for the individual country context. The World Health Organization (WHO) and the Pan American Health Organization (PAHO) established a standard, simplified Global HEARTS approach to hypertension control, including preferred antihypertensive medicines and blood pressure measurement devices. The objective of this study is to report on health economic studies of HEARTS hypertension control package cost (especially medication costs), cost-effectiveness, and budget impact and describe mathematical models designed to translate hypertension control program data into the optimal approach to hypertension care service delivery and financing, especially in lowand middle-income countries. Early results suggest that HEARTS hypertension control interventions are either cost-saving or cost-effective, that the HEARTS package is affordable at between US$ 18-44 per person treated per year, and that antihypertensive medicines could be priced low enough to reach a global standard of an average <US$ 5 per patient per year in the public sector. This health economic evidence will make a compelling case for government ownership and financial support for national scale hypertension control programs.

[RESUMEN]. En general, los programas de control de la hipertensión son costo-eficaces, incluso en los países de ingresos bajos y medios. Aun así, es poco probable que los gobiernos nacionales y la sociedad civil apoyen los programas de control de la hipertensión a menos que se demuestre su valor en términos de beneficios para la salud pública, impacto presupuestario y valor de la inversión para el contexto individual del país. La Organización Mundial de la Salud (OMS) y la Organización Panamericana de la Salud (OPS) implementaron la iniciativa HEARTS, un enfoque mundial estandarizado y simplificado para el control de la hipertensión, que incluye los medicamentos antihipertensivos y los dispositivos de medición de la presión arterial de preferencia. El objetivo de este estudio es informar sobre los estudios en el ámbito de la economía de la salud relativos al costo de las medidas de control de la hipertensión previstas en HEARTS (especialmente, de los medicamentos), la costo-efectividad y el impacto presupuestario, así como describir los modelos matemáticos diseñados para traducir los datos de este programa en un enfoque óptimo para la prestación y el financiamiento de los servicios de atención de la hipertensión, especialmente en países de ingresos medianos y bajos. Los primeros resultados indican que las intervenciones de HEARTS para el control de la hipertensión son de bajo costo o costo-eficaces, que el conjunto de medidas HEARTS es asequible, a un precio que oscila entre US$ 18 y US$ 44 al año por paciente tratado, y que los medicamentos antihipertensivos podrían tener un precio lo suficientemente bajo como para alcanzar un estándar medio mundial de <US$ 5 por paciente al año en el sector público. Estos datos del ámbito de la economía de la salud serán argumentos convincentes para que los gobiernos se involucren en los programas de control de la hipertensión a escala nacional y les brinden apoyo financiero.

[RESUMO]. Geralmente, os programas de controle de hipertensão são custo-efetivos, inclusive em países de baixa e média renda, mas os governos dos países e a sociedade civil provavelmente não apoiarão tais programas a menos que demonstrem valor em termos de benefícios à saúde pública, impacto orçamentário e retorno sobre o investimento no contexto individual do país. A Organização Mundial da Saúde (OMS) e a Organização Pan-Americana da Saúde (OPAS) criaram a Global HEARTS, uma abordagem padrão e simplificada ao controle da hipertensão arterial, que inclui medicamentos anti-hipertensivos preferidos e dispositivos para aferição da pressão arterial preferidos. O objetivo deste estudo é relatar os estudos de economia em saúde que analisaram o custo (especialmente custos de medicamentos), custo-benefício e impacto orçamentário do pacote HEARTS para controle da hipertensão e descrever modelos matemáticos elaborados para traduzir os dados do programa de controle de hipertensão em uma abordagem ideal para a prestação e financiamento de serviços de atenção às pessoas com hipertensão, especialmente em países de baixa e média renda. Os primeiros resultados sugerem que as intervenções HEARTS para controle da hipertensão são de baixo custo ou custo-efetivas, que o pacote HEARTS é acessível (custando de US$ 18 a 44 por pessoa tratada por ano) e que o preço dos medicamentos anti-hipertensivos poderia ser baixo o suficiente para atingir uma média global de <US$ 18 por paciente por ano no setor público. Estas evidências do campo da economia em saúde serão um argumento convincente para que os governos se responsabilizem por programas de controle de hipertensão em escala nacional e os dotem de recursos financeiros.
