RESUMO
Hypertension remains the leading cause of cardiovascular disease globally despite the availability of safe and effective treatments. Unfortunately, many barriers exist to controlling hypertension, including a lack of effective screening and awareness, an inability to access treatment and challenges with its management when it is treated. Addressing these barriers is complex and requires engaging in a systematic and sustained approach across communities over time. This analysis aims to describe the key elements needed to create an effective delivery system for hypertension control. A successful system requires political will and supportive leadership at all levels of an organization, including at the point of care delivery (office or clinic), in the health care system, and at regional, state and national levels. Effective screening and outreach systems are necessary to identify individuals not previously diagnosed with hypertension, and a system for follow up and tracking is needed after people are diagnosed. Implementing simple protocols for treating hypertension can reduce confusion among providers and increase treatment efficiency. Ensuring easy access to safe, effective and affordable medications can increase blood pressure control and potentially decrease health care system costs. Task-sharing among members of the health care team can expand the services that are delivered. Finally, monitoring of and reporting on the performance of the health care team are needed to learn from those who are doing well, disseminate ideas to those in need of improvement and identify individual patients who need outreach or additional care. Successful large-scale hypertension programs in different settings share many of these key elements and serve as examples to improve systems of hypertension care delivery throughout the world.
A pesar de la disponibilidad de tratamientos seguros y efectivos, la hipertensión sigue siendo la principal causa de enfermedad cardiovascular a nivel mundial. Lamentablemente, el control de la hipertensión enfrenta muchos obstáculos, como la falta de detección y concientización efectivas, la incapacidad de acceder al tratamiento y los retos que plantea su manejo cuando se recibe tratamiento. Resulta complejo abordar estos obstáculos; se debe adoptar un enfoque sistemático y sostenido en todas las comunidades a lo largo del tiempo. El presente análisis tiene como objetivo describir los elementos clave necesarios para crear un sistema de atención eficaz para el control de la hipertensión. Un sistema adecuado precisa voluntad política y un liderazgo que brinde apoyo en todos los niveles de una organización, incluido el punto donde se presta la atención (consultorio o clínica), el sistema de atención de salud y a nivel regional, estatal y nacional. Se necesitan sistemas efectivos de detección y de alcance comunitario para encontrar a las personas sin diagnóstico previo de hipertensión, así como un sistema para el seguimiento y la localización una vez han sido diagnosticadas. La aplicación de protocolos simples para tratar la hipertensión puede reducir la confusión entre los proveedores y aumentar la eficiencia del tratamiento. Garantizar un acceso fácil a medicamentos seguros, efectivos y asequibles puede aumentar el control de la presión arterial y potencialmente disminuir los costos para el sistema de atención de salud. La distribución de tareas entre los miembros del equipo de atención de salud permite expandir los servicios que se prestan. Finalmente, es necesario dar seguimiento al desempeño del equipo de atención de salud y presentar información al respecto, a fin de aprender de las buenas prácticas, difundir ideas entre quienes necesitan mejorar y determinar a cuáles pacientes se debe llegar y cuáles necesitan atención adicional. Los programas de hipertensión a gran escala con buenos resultados en diferentes entornos comparten muchos de estos elementos clave y sirven como ejemplos para mejorar la atención de la hipertensión en todo el mundo.
A hipertensão continua sendo a principal causa de doenças cardiovasculares no mundo, apesar da disponibilidade de tratamentos seguros e eficazes. Infelizmente, existem muitas barreiras para o controle da hipertensão, incluindo a falta de rastreamento e a conscientização eficazes, a incapacidade de acesso ao tratamento e desafios de conduta clínica quando ela é tratada. A abordagem dessas barreiras é complexa e requer um enfoque sistemático e sustentado em diferentes comunidades ao longo do tempo. Esta análise tem como objetivo descrever os elementos-chave necessários para criar um sistema eficaz de prestação de intervenções para o controle da hipertensão. Um sistema de sucesso requer vontade política e liderança que o apoie em todos os níveis de uma organização, inclusive no ponto da prestação de cuidados (consultório ou clínica), no sistema de saúde e nos níveis regional, estadual e nacional. Sistemas eficazes de triagem e acolhida são necessários para identificar indivíduos com hipertensão não diagnosticada, e um sistema de acompanhamento e rastreamento após o diagnóstico se faz igualmente necessário. A implementação de protocolos simples para o tratamento da hipertensão pode reduzir a confusão entre os profissionais de saúde e aumentar a eficiência do tratamento. Garantir o fácil acesso a medicamentos seguros, eficazes e acessíveis pode aumentar o controle da pressão arterial e potencialmente diminuir os custos do sistema de saúde. A divisão de tarefas entre os integrantes da equipe de saúde pode expandir os serviços prestados. Finalmente, é necessário monitorar e informar acerca do desempenho da equipe de saúde para aprender com aqueles que estão indo bem, disseminar ideias para aqueles que precisam melhorar e identificar pacientes individuais que precisam de ajuda ou cuidados adicionais. Programas bem-sucedidos de controle da hipertensão em larga escala em diferentes ambientes compartilham muitos desses elementos-chave e servem como exemplos para melhorar os sistemas de atenção à hipertensão em todo o mundo.
RESUMO
BACKGROUND: To be sustainable, pharmacists providing direct patient care must receive appropriate payment for these services. This prespecified substudy of the RxACTION trial (a randomized trial of pharmacist prescribing vs usual care in patients with above-target blood pressure [BP]) aimed to determine if BP reduction achieved differed between patients whose pharmacist was paid by pay-for-performance (P4P) vs fee-for-service (FFS). METHODS: Within RxACTION, patients with elevated BP assigned to the pharmacist prescribing group were further randomized to P4P or FFS payment for the pharmacist. In FFS, pharmacists received $150 for the initial visit and $75 for follow-up visits. P4P included FFS payments plus incentives of $125 and $250 for each patient who reached 50% and 100% of the BP target, respectively. The primary outcome was difference in change in systolic BP between P4P and FFS groups. RESULTS: A total of 89 patients were randomized to P4P and 92 to the FFS group. Patients' average (SD) age was 63.0 (13.2) years, 49% were male and 76% were on antihypertensive drug therapy at baseline, taking a median of 2 (interquartile range = 1) medications. Mean systolic BP reductions in the P4P and FFS groups were 19.7 (SD = 18.4) vs 17.0 (SD = 16.4) mmHg, respectively (p = 0.47 for the comparison of deltas and p = 0.29 after multivariate adjustment). CONCLUSIONS: This trial of pharmacist prescribing found substantial reductions in systolic BP among poorly controlled hypertensive individuals but with no appreciable difference when pharmacists were paid by P4P vs FFS.
RESUMO
Spot urine samples with estimating equations have been used to assess individuals' sodium (salt) intake in association with health outcomes. There is large random and systematic error in estimating sodium intake using this method and spurious health outcome associations. Substantial controversy has resulted from false claims the method is valid. Hence, the World Hypertension League, International Society of Hypertension and Resolve to Save Lives, supported by 21 other health organizations, have issued this policy statement that strongly recommends that research using spot urine samples with estimating equations to assess individuals' sodium (salt) intake in association with health outcomes should not be conducted, funded or published. Literature reviews on the health impacts of reducing dietary sodium that include studies that have used spot and short duration timed urine samples with estimating equations need to explicitly acknowledge that the method is not recommended to be used and is associated with spurious health outcome associations.

Hypertension is a leading preventable and controllable risk factor for cardiovascular and cerebrovascular diseases and the leading preventable risk for death globally. With a prevalence of nearly 50% and 93% of cases uncontrolled, very little progress has been made in detecting, treating, and controlling hypertension in Africa over the past thirty years. We propose the African Control of Hypertension through Innovative Epidemiology and a Vibrant Ecosystem (ACHIEVE) to implement the HEARTS package for improved surveillance, prevention, treatment/acute care of hypertension, and rehabilitation of those with hypertension complications across the life course. The ecosystem will apply the principles of an iterative implementation cycle by developing and deploying pragmatic solutions through the contextualization of interventions tailored to navigate barriers and enhance facilitators to deliver maximum impact through effective communication and active participation of all stakeholders in the implementation environment. Ten key strategic actions are proposed for implementation to reduce the burden of hypertension in Africa.
RESUMO
There is increasing recognition in Canada and elsewhere of the need for population-level interventions related to diet. One example of such an intervention is a ban on the marketing of foods/beverages to children, for which several health organizations have or are in the process of developing position statements. Considering the federal government's inaction to impose restrictions that would yield meaningful impact, there is opportunity for the health community to unite in support of a stronger set of policies. However, several issues and challenges exist, some of which we outline in this commentary. We emphasize that, despite challenges, the present and predicted future of diet-related illness in Canadian children is such that population-level intervention is necessary and becoming increasingly urgent, and there is an important role for the health community in facilitating action.

Hypertension is the leading preventable risk factor for cardiovascular diseases and disability globally. In low- and middle-income countries hypertension has a major social impact, increasing the disease burden and costs for national health systems. The present call to action aims to stimulate all African countries to adopt several solutions to achieve better hypertension management. The following 3 goals should be achieved in Africa by 2030: (1) 80% of adults with high blood pressure in Africa are diagnosed; (2) 80% of diagnosed hypertensives, that is, 64% of all hypertensives, are treated; and (3) 80% of treated hypertensive patients are controlled. To achieve these aims, we call on individuals and organizations from government, private sector, health care, and civil society in Africa and indeed on all Africans to undertake a few specific high priority actions. The aim is to improve the detection, diagnosis, management, and control of hypertension, now considered to be the leading preventable killer in Africa.

BACKGROUND: Indo-Asians in Canada are at increased risk for cardiovascular diseases. There is a need for cultural and language specific educational materials relating to this risk. During this project we developed and field tested the acceptability of a hypertension public education pamphlet tailored to fit the needs of an at risk local Indo-Asian population, in Calgary, Alberta, Canada. METHODS: A community health board representing Calgary's Indo-Asian communities identified the culturally specific educational needs and language preferences of the local population. An adaptation of an existing English language Canadian Public Hypertension Recommendations pamphlet was created considering the literacy and translation challenges. The adapted pamphlet was translated into four Indo-Asian languages. The adapted pamphlets were disseminated as part of the initial educational component of a community-based culturally and language-sensitive cardiovascular risk factor screening and management program. Field testing of the materials was undertaken when participants returned for program follow-up seven to 12 months later. RESULTS: Fifty-nine English-speaking participants evaluated and confirmed the concept validity of the English adapted version. 28 non-English speaking participants evaluated the Gujarati (N = 13) and Punjabi (N = 15) translated versions of the adapted pamphlets. All participants found the pamphlets acceptable and felt they had improved their understanding of hypertension. CONCLUSIONS: Involving the target community to identify health issues as well as help to create culturally, language and literacy sensitive health education materials ensures resources are highly acceptable to that community. Minor changes to the materials will be needed prior to formal testing of hypertension knowledge and health decision-making on a larger scale within this at risk community.

BACKGROUND: Hypertension continues to be the leading cause of preventable death and disability. The objective of this study was to examine hypertension prevalence, awareness, treatment, and control for women and men in Canada over the last decade. METHODS: A nationally representative, cross-sectional study was conducted using the Canadian Health Measures Survey (2007-2017). Using blood pressure readings from each respondent, along with a self-reported history of high blood pressure and active medications, the rates of hypertension prevalence, awareness, treatment, and control were calculated for women and men. RESULTS: A total of 5,794,641 people were identified to have hypertension from 2007 to 2017, representing 23.1% (95% confidence interval [CI], 21.9%-24.2%) of the Canadian adult population with no appreciable change in prevalence over the decade. Overall awareness, treatment, and control were 83.5% (95% CI, 81.5%-85.4%), 78.9% (95% CI, 76.2%-81.6%), and 65.4% (95% CI, 62.4%-68.4%), respectively, with no significant changes in men from 2007 to 2017. Conversely, in women, substantial deteriorations in awareness (72.2% [95% CI, 64.1%-80.2%] in 2016-2017 vs 85.0% [95% CI, 82.4%-87.7%] in 2007-2015), treatment (65.2% [95% CI, 57.6%-72.8%] vs 82.2% [95% CI, 79.4%-85.1%]), and control (49.2% [95% CI, 39.7%-58.7%] vs 67.0% [95% CI, 63.9%-70.1%]) were found. CONCLUSIONS: After plateauing early in the 2000s, Canadian hypertension treatment and control rates have declined in the past decade, largely in women. Renewed collaborative efforts by key stakeholders are urgently needed to address this increase in preventable risk for cardiovascular disease.

INTRODUCTION: High dietary sodium is a leading contributor to hypertension, and hypertension is the leading underlying cause of death globally. There is a robust body of evidence supporting the health benefits of sodium reduction. Sodium intake in South Korea is high, with about half the population consuming >4000 mg/day, twice the recommended upper limit. METHODS: In 2012, South Korea implemented its National Plan to Reduce Sodium Intake, with a goal of reducing population sodium consumption by 20%, to 3900 mg/day, by 2020. The plan included five key components: (1) a consumer awareness campaign designed to change food consumption behaviours; (2) increased availability of low-sodium foods at schools and worksites; (3) increased availability of low-sodium meals in restaurants; (4) voluntary reformulation of processed foods to lower sodium content; and (5) development of low-sodium recipes for food prepared at home. Monitoring and evaluation included tracking sodium intake and sources of dietary sodium using the Korea National Health and Nutrition Examination Survey. RESULTS: By 2014, South Korea had reduced dietary sodium consumption among adults by 23.7% compared to a survey conducted in 2010 prior to implementation of a nationwide salt reduction campaign that used this comprehensive, multipronged approach. The reductions in sodium intake were accompanied by reductions in population blood pressure and hypertension prevalence. Although causal associations between the sodium reduction programme and reduced sodium intake cannot be made, the declines occurred with the introduction of the programme. CONCLUSION: Multicomponent interventions have great potential to reduce population sodium intake. Lessons learnt from South Korea could be applied to other countries and are likely very relevant to other Asian countries with similar food sources and consumption profiles.

Clinical practice guidelines recommend several routine laboratory tests in patients diagnosed with hypertension. However, the rates of clinically relevant laboratory abnormalities are unknown. Therefore, we conducted a retrospective cohort study using administrative and laboratory data of patients diagnosed with hypertension between April 2010 and March 2015 in Alberta, Canada. Laboratory investigations for renal function, serum electrolytes (sodium and potassium), low-density lipoprotein (LDL) cholesterol, and diabetes (fasting blood glucose and hemoglobin A1c), measured within 1 year of diagnosis, were examined, and the frequency of abnormalities determined. A total of 225 296 cases of incident hypertension were identified. Of these, 74.3% received at least one of the four guideline-recommended laboratory tests, but only 42.3% received all four tests. Patients who received any testing, compared to subjects who did not, were on average older (median age 55.9 vs 51.2 years, P < .001) and had more comorbidity (14.5% vs 2.8% with a Charlson comorbidity index ≥ 3, P < .001). Laboratory abnormalities with the potential to affect clinical decision-making were more common among multi-comorbid patients. Patients with renal dysfunction (6.7% vs 11.6%, 26.3%, P < .001), electrolyte abnormalities (9.8% vs 12.6%, 20.5%, P < .001), and diabetes (13.4% vs 25.1% vs 38.8%, P < .001) were found in patients with Charlson scores of 0 vs 1-2 vs ≥3, respectively. Our study found most patients diagnosed with hypertension received some laboratory testing, but rates of laboratory testing and frequency of abnormalities varied by clinical context. Testing and abnormalities detected were both more common among older patients and patients with comorbidities.

OBJECTIVE: To determine whether major depression (MD) leads to an increased risk of new-onset high blood pressure diagnoses. METHODS: The data source was the Canadian National Population Health Survey (NPHS). The NPHS included a short-form version of the Composite International Diagnostic Interview (CIDI-SF) to assess MD and collected self-report data about professionally diagnosed high blood pressure and the use of antihypertensive medications. The analysis included 12,270 respondents who did not report high blood pressure or the use of antihypertensive medications at a baseline interview conducted in 1994. Proportional hazards models were used to compare the incidence of high blood pressure in respondents with and without MD during 10 years of subsequent follow-up. RESULTS: After adjustment for age, the risk of developing high blood pressure was elevated in those with MD. The hazard ratio was 1.6 (95% Confidence Interval = 1.2-2.1), p = .001, indicating a 60% increase in risk. Adjustment for additional covariates did not alter the association. CONCLUSIONS: MD may be a risk factor for new-onset high blood pressure. Epidemiologic data cannot definitely confirm a causal role, and the association may be due to shared etiologic factors. However, the increased risk may warrant closer monitoring of blood pressure in people with depressive disorders.

The Science of Salt reviews identify, summarize, and critically appraise published studies on dietary salt and health outcomes according to pre-specified methods. This review covers the period April 3 to October 30, 2018. Here, nineteen studies that fit pre-specified criteria for review and summary are included. Three of these, one prospective cohort study, one randomized controlled trial, and a post hoc analysis of the Dietary Approaches to Stop Hypertension (DASH) sodium trial fulfilled the quality criteria for detailed critical appraisal, including risk of bias assessment, and commentary. Two trials demonstrated a positive association between salt intake and blood pressure. In a cohort of older Italians, increased risk of total mortality was observed with salt intake less than ~16 g/d (6300 mg sodium/d) at baseline; no association existed for incident cardiovascular disease (CVD) or CVD mortality. The paucity of published studies which met our criteria for methodological quality is of concern.

This review aims to summarize and synthesize studies reporting on changes in sodium levels in packaged food products, restaurant foods, and hospital or school meals, as a result of salt reduction interventions. Studies were extracted from those published in the Science of Salt Weekly between June 2013 and February 2018. Twenty-four studies were identified: 17 assessed the changes in packaged foods, four in restaurant foods, two in hospital or school meals, and one in both packaged and restaurant foods. Three types of interventions were evaluated as part of the studies: voluntary reductions (including targets), labeling, and interventions in institutional settings. Decreases in sodium were observed in all studies (n = 8) that included the same packaged foods matched at two time points, and in the studies carried out in hospitals and schools. However, there was little to no change in mean sodium levels in restaurant foods. The pooled analysis of change in sodium levels in packaged foods showed a decrease in sodium in unmatched food products (-36 mg/100 g, 95% CI -51 to -20 mg/100 g) and in five food categories-breakfast cereals, breads, processed meats, crisps and snacks, and soups. Twenty-two of the 24 studies were from high-income countries, limiting the applicability of the findings to lower resource settings.

The Global Burden of Disease (GBD) 2010 study estimated national salt intake for 187 countries based on data available up to 2010. The purpose of this review was to identify studies that have measured salt intake in a nationally representative population using the 24-hour urine collection method since 2010, with a view to updating evidence on population salt intake globally. Studies published from January 2011 to September 2018 were searched for from MEDLINE, Scopus, and Embase databases using relevant terms. Studies that provided nationally representative estimates of salt intake among the healthy adult population based on the 24-hour urine collection were included. Measured salt intake was extracted and compared with the GBD estimates. Of the 115 identified studies assessed for eligibility, 13 studies were included: Four studies were from Europe, and one each from the United States, Canada, Benin, India, Samoa, Fiji, Barbados, Australia, and New Zealand. Mean daily salt intake ranged from 6.75 g/d in Barbados to 10.66 g/d in Portugal. Measured mean population salt intake in Italy, England, Canada, and Barbados was lower, and in Fiji, Samoa, and Benin was higher, in recent surveys compared to the GBD 2010 estimates. Despite global targets to reduce population salt intake, only 13 countries have published nationally representative salt intake data since the GBD 2010 study. In all countries, salt intake levels remain higher than the World Health Organization's recommendation, highlighting the need for additional global efforts to lower salt intake and monitor salt reduction strategies.
