Hypertension,knowledge, attitudes,and practices of primary care physicians in Ulaanbaatar,Mongolia

We examined the knowledge, attitudes, and practices of primary care doctors in Ulaanbaatar, Mongolia using a recently developed World Hypertension League survey. The survey was administered as part of a quality assurance initiative to enhance hypertension control. A total of 577 surveys were distributed and 467 were completed (81% response rate). The respondents had an average age of 35 years and 90.1% were female. Knowledge of hypertension epidemiology was low (13.5% of questions answered correctly); 31% of clinical practice questions had correct answers and confidence in performing specific tasks to improve hypertension control had 63.2% “desirable/correct” answers. Primary care doctors mostly had a positive attitude toward hypertension management (76.5% desirable/correct answers) and highly prioritized hypertension management activities (85.7% desirable/correct answers). Some important highlights included the majority (> 80%) overestimating hypertension awareness, treatment, and control rates; 78.2% used aneroid blood pressure manometers; 15% systematically screened adults for hypertension in their clinics; 21.8% reported 2 or more drugs were required to control hypertension in most people; and 16.1% reported most people could be controlled by lifestyle changes alone. 55% of respondents were not comfortable prescribing more than 1 or 2 antihypertensive drugs in a patient and the percentage of desirable/correct responses to treating various high‐risk patients was low. Most (53%‐74%) supported task shifting to nonphysician health care providers except for drug prescribing, which only 13.9% supported. A hypertension clinical education program is currently being designed based on the specific needs identified in the survey.     

The World Hypertension League: Goals and Perspectives

The World Hypertension League (WHL) is a federation of currently 51 national and regional organizations, committed to the prevention of hypertension. The objectives of the WHL are to promote the prevention, detection, and control of hypertension in populations by liaising with the member organizations, promoting the exchange of information among them, and offering internationally applicable methods and programs for hypertension control. This article describes objectives and policies, as well as projects and ongoing activities of the WHL.     

Barriers,facilitators, and effective interventions for lowering cardiovascular disease risk in people with severe mental illnesses: evidence from a systematic review and focus group study

BackgroundPeople with severe mental illnesses die early from cardiovascular disease (CVD). They have increased CVD risk factors, yet are less likely to receive appropriate treatments. Little is known about effective interventions to reduce CVD risk in severe mental illness. This study aimed to consolidate the best available evidence on lowering CVD risk in severe mental illness in primary care.Methods75 participants took part in 14 focus groups. Participants included people with severe mental illness, general practitioners, practice nurses, community mental health staff, and carers. Staff were asked to identify the training, resources, and systems required to lower CVD risk in severe mental illness, while access to services, motivation, and capability to lower CVD risk were explored with people with severe mental illness. Effective interventions were identified through a systematic review. We searched the Cochrane Library for systematic reviews of randomised controlled trials (RCTs) and the Cochrane Schizophrenia and Cochrane Depression, Anxiety and Neurosis Group Trial Registers between 1966 and 2014 for additional RCTs. Search terms were (schizophrenia, severe mental illness, bipolar, mania, manic, hypomani*, psychos*, psychotic, rapid cycling, schizoaffective) AND (physical, cardio*, metabolic, weight, tobacco, smok, medical, alcohol, nutrition, diet, health, diabet*, blood pressure, hypertension, cholesterol, statin). Non-English language papers were excluded. Data from included studies were extracted with a template to record methodological and substantive characteristics.FindingsFocus groups identified five barriers: negative perceptions of severe mental illnesses, difficulties accessing services, difficulties managing a healthy lifestyle, not attending appointments, and lack of awareness of CVD risk. Five facilitators included social support, improving patient engagement, continuity of care, positive feedback, and goal setting. 15 systematic reviews and 28 additional RCTs were included. Effective pharmacological and behavioural interventions to manage weight and promote smoking cessation or reduction were identified. There was minimal evidence of effective interventions to reduce alcohol use and blood glucose and no evidence for interventions targeting cholesterol, hypertension, or diabetes.InterpretationCVD risk attributable to weight and smoking can be reduced in severe mental illness; other risk factors must currently be managed as for other populations. However we identified factors that can be incorporated in the design, delivery, and evaluation of services to reduce CVD risk for people with severe mental illness in primary care. New interventions should address these barriers and harness facilitating factors to reduce CVD risk in this population.FundingThis work was funded as part of a National Institute for Health Research Programme grant for applied research (ref RP-PG-0609-10156).     

Monitoring and evaluation framework for hypertension programs. A collaboration between the Pan American Health Organization and World Hypertension League

The Pan American Health Organization (PAHO)–World Hypertension League (WHL) Hypertension Monitoring and Evaluation Framework is summarized. Standardized indicators are provided for monitoring and evaluating national or subnational hypertension control programs. Five core indicators from the World Health Organization hearts initiative and a single PAHO‐WHL core indicator are recommended to be used in all hypertension control programs. In addition, hypertension control programs are encouraged to select from 14 optional qualitative and 33 quantitative indicators to facilitate progress towards enhanced hypertension control. The intention is for hypertension programs to select quantitative indicators based on the current surveillance mechanisms that are available and what is feasible and to use the framework process indicators as a guide to program management. Programs may wish to increase or refine the number of indicators they use over time. With adaption the indicators can also be implemented at a community or clinic level. The standardized indicators are being pilot tested in Cuba, Colombia, Chile, and Barbados.     

World Hypertension Day and global awareness

The World Health Organization attributes hypertension, or high blood pressure, as the leading cause of cardiovascular mortality. The World Hypertension League (WHL), an umbrella organization of 85 national hypertension societies and leagues, recognized that more than 50% of the hypertensive population worldwide are unaware of their condition. To address this problem, the WHL initiated a global awareness campaign on hypertension in 2005 and dedicated May 17 of each year as World Hypertension Day (WHD). Over the past three years, more national societies have been engaging in WHD and have been innovative in their activities to get the message to the public. In 2007, there was record participation from 47 member countries of the WHL. During the week of WHD, all these countries -- in partnership with their local governments, professional societies, nongovernmental organizations and private industries -- promoted hypertension awareness among the public through several media and public rallies. Using mass media such as Internet and television, the message reached more than 250 million people. As the momentum picks up year after year, the WHL is confident that almost all the estimated 1.5 billion people affected by elevated blood pressure can be reached. The success of WHD is due to the enthusiasm and voluntary action of multiple stakeholders from every member country.     

Assessing healthcare professional knowledge,attitudes, and practices on hypertension management. Announcing a new World Hypertension League resource

To assist hypertension control programs and specifically the development of training and education programs on hypertension for healthcare professionals, the World Hypertension League has developed a resource to assess knowledge, attitudes, and practices on hypertension management. The resource assesses: (1) the importance of hypertension as a clinical and public health risk; (2) education in national or international hypertension recommendations; (3) lifestyle causes of hypertension; (4) measurement of blood pressure, screening, and diagnosis of hypertension; (5) lifestyle therapy counseling; (6) cardiovascular risk assessment; (7) antihypertensive drug therapy; and (8) adherence to therapy. In addition, the resource assesses the attitudes and practices of healthcare professionals for task sharing/shifting, use of care algorithms, and use of registries with performance reporting functions. The resource is designed to help support the Global Hearts Alliance to provide standardized and enhanced hypertension control globally.     

Hypertension prevalence and control in Ulaanbaatar,Mongolia

This study examines the prevalence, awareness, treatment, and control of hypertension in Ulaanbaatar, Mongolia, using both the American Heart Association and conventional thresholds (130/80 and 140/90 mm Hg, respectively). In this randomized cross‐sectional study, two‐stage cluster sampling was used to obtain a sample of 4515 individuals aged ≥20 years. Hypertension was defined by the use of antihypertensives in the last 2 weeks or a blood pressure at or above the thresholds of 140/90 and 130/80 mm Hg. The mean age of the participants was 41.1 ± 14.0 years and 54.5% were women. Hypertension prevalence was 25.6% (using 140/90 mm Hg) and 46.5% (using 130/80 mm Hg). Prevalence increased with age and below 50 years men were consistently more likely to be hypertensive. Among hypertensive participants, the rates of awareness, treatment, and control were 69.7%, 46.8%, and 24.0% (using 140/90 mm Hg) and 49.1%, 25.8%, and 6.4% (using 130/80 mm Hg, respectively). Men had lower rates of awareness, treatment, and control compared with women, with the most pronounced differences at younger ages. This study shows that awareness, treatment, and control rates in Ulaanbaatar are better than in most low‐ and middle‐income countries but are still suboptimal. The largest “care gap” was in young men where a regulatory requirement for annual workplace blood pressure screening has the potential to enhance care. A major hypertension control program has just been initiated in Ulaanbaatar.     

Prevalence, treatment, and control of hypertension in primary care: gaps, trends, and opportunities

Since most cases of hypertension are managed in family practice, estimates of the prevalence, treatment, and control in the primary care population are needed to adequately address the burden of hypertension in Canada as it has in other countries. The authors used a large primary care research database to determine the prevalence of hypertension between 2000 and 2003. Blood pressure recordings were used to estimate the rates of prevalence, treatment, and control of hypertension for the overall population and for important subgroups. The prevalence of hypertension was 17.3%, most patients had untreated hypertension (68.6%), and only 15.8% had blood pressure treated and controlled. Higher rates of treatment and control were observed among older adults, those with type II diabetes, and those with a previous myocardial infarction. Odds of achieving target blood pressure were significantly better when combination therapy vs monotherapy was used. The prevalence of hypertension in primary care is high and most patients remain untreated; however, increased risk appears to lead to better treatment and control.     

Residual risk for acute stroke in patients with type 2 diabetes and hypertension in primary care: Skaraborg Hypertension and Diabetes Project

AIM: The aim of this study was to investigate the risk of acute stroke in subgroups of patients treated for hypertension and type 2 diabetes in primary care. METHODS: Patients with hypertension only (n = 695), type 2 diabetes only (n = 181) or both (n = 240), who consecutively attended an annual control in primary care in Skara, Sweden during 1992-1993, were evaluated for cardiovascular disease risk factors and enrolled in this study. Subjects with neither hypertension nor type 2 diabetes (n = 824) who participated in a population survey in the same community served as controls. Possible events of acute stroke through 2002 were validated using hospital records and death certificates. RESULTS: During a mean follow-up time of 8.4 years, 190 first events of acute stroke, fatal or non-fatal, were ascertained. Risk factor levels were generally higher in all patient categories than in controls. Stroke risk was significantly increased in all male patients: hazard ratio 4.2 (95% CI 2.1-8.4) in patients with both conditions, 3.3 (1.5-7.0) in those with type 2 diabetes alone and 2.8 (1.5-5.3) in those with hypertension alone (adjusted for age, total cholesterol, current smoking, BMI and physical activity). Corresponding findings in women were 2.9 (1.5-5.8) in patients with type 2 diabetes only and 2.4 (1.2-4.7) in those with both conditions. However, in women with hypertension only, a significant risk was seen first when subjects were truncated at 85 years of age. There were too few fatal stroke events for conclusive results on stroke mortality. CONCLUSIONS: A considerable risk of acute stroke remains in patients with type 2 diabetes and hypertension. Strategies for stricter multiple risk factor interventions should be implemented in primary care.     

Impact of Computerized Decision Support on Blood Pressure Management and Control: A Randomized Controlled Trial

BACKGROUND We conducted a cluster randomized controlled trial to examine the effectiveness of computerized decision support (CDS) designed to improve hypertension care and outcomes in a racially diverse sample of primary care patients. METHODS We randomized 2,027 adult patients receiving hypertension care in 14 primary care practices to either 18 months of their physicians receiving CDS for each hypertensive patient or to usual care without computerized support for the control group. We assessed prescribing of guideline-recommended drug therapy and levels of blood pressure control for patients in each group and examined if the effects of the intervention differed by patients’ race/ethnicity using interaction terms. MEASUREMENTS AND MAIN RESULTS Rates of blood pressure control were 42% at baseline and 46% at the outcome visit with no significant differences between groups. After adjustment for patients’ demographic and clinical characteristics, number of prior visits, and levels of baseline blood pressure control, there were no differences between intervention groups in the odds of outcome blood pressure control. The use of CDS to providers significantly improved Joint National Committee (JNC) guideline adherent medication prescribing compared to usual care (7% versus 5%, P < 0.001); the effects of the intervention remained after multivariable adjustment (odds ratio [OR] 1.39 [CI, 1.13–1.72]) and the effects of the intervention did not differ by patients’ race and ethnicity. CONCLUSIONS CDS improved appropriate medication prescribing with no improvement in disparities in care and overall blood pressure control. Future work focusing on improvement of these interventions and the study of other practical interventions to reduce disparities in hypertension-related outcomes is needed.     

Mapping stages,barriers and facilitators to the implementation of HEARTS in the Americas initiative in 12 countries: A qualitative study

The World Health Organization (WHO) Global Hearts Initiative offers technical packages to reduce the burden of cardiovascular diseases through population‐wide and targeted health services interventions. The Pan American Health Organization (PAHO) has led implementation of the HEARTS in the Americas Initiative since 2016. The authors mapped the developmental stages, barriers, and facilitators to implementation among the 371 primary health care centers in the participating 12 countries. The authors used the qualitative method of document review to examine cumulative country reports, technical meeting notes, and reports to regional stakeholders. Common implementation barriers include segmentation of health systems, overcoming health care professionals'' scope of practice legal restrictions, and lack of health information systems limiting operational evaluation and quality improvement mechanisms. Main implementation facilitators include political support from ministries of health and leading scientific societies, PAHO''s role as a regional catalyst to implementation, stakeholder endorsement demonstrated by incorporating HEARTS into official documents, and having a health system oriented to primary health care. Key lessons include the need for political commitment and cultivating on‐the‐ground leadership to initiate a shift in hypertension care delivery, accompanied by specific progress in the development of standardized treatment protocols and a set of high‐quality medicines. By systematizing an implementation strategy to ease integration of interventions into delivery processes, the program strengthened technical leadership and ensured sustainability. These study findings will aid the regional approach by providing a staged planning model that incorporates lessons learned. A systematic approach to implementation will enhance equity, efficiency, scale‐up, and sustainability, and ultimately improve population hypertension control.     

WHO HEARTS: A Global Program to Reduce Cardiovascular Disease Burden: Experience Implementing in the Americas and Opportunities in Canada

Globally, cardiovascular diseases (CVDs) are the leading cause of death. Viewed as a threat to the global economy, the United Nations included reducing noncommunicable diseases, including CVDs, in the 2030 sustainable development goals, and the World Health Assembly agreed to a target to reduce noncommunicable diseases 25% by the year 2025. In response, the World Health Organisation led the development of HEARTS, a technical package to guide governments in strengthening primary care to reduce CVDs. HEARTS recommends a public health and health system approach to introduce highly simplified interventions done systematically at a primary health care level and has a focus on hypertension as a clinical entry point. The HEARTS modules include healthy lifestyle counselling, evidence-based treatment protocols, access to essential medicines and technology, CVD risk-based management, team-based care, systems for monitoring, and an implementation guide. There are early positive global experiences in implementing HEARTS. Led by the Pan American Health Organisation, many national governments in the Americas are adopting HEARTS and have shown early success. Unfortunately, in Canada hypertension control is declining in women since 2010-2011 and the dramatic reductions in rates of CVD seen before 2010 have flattened when age adjusted and increased for rates that are not age adjusted, and there are marked increases in absolute numbers of Canadians with adverse CVD outcomes. Several steps that Canada could take to enhance hypertension control are outlined, the core of which is to implement a strong governmental nongovernmental collaborative strategy to prevent and control CVDs, focusing on HEARTS.     

Educational outreach in diabetes to encourage practice nurses to use primary care hypertension and hyperlipidaemia guidelines (EDEN): a randomized controlled trial.

OBJECTIVE: To determine the effectiveness of specialist nurse delivered education in primary care to improve control of hypertension and hyperlipidaemia in patients with diabetes. DESIGN AND SETTING: Practice-level randomized controlled trial, Salford, England. SUBJECTS: From 44 practices, 10 303 subjects presenting in general practice with raised blood pressure (= 140/80 mmHg), raised total cholesterol (= 5.0 mmol/l) or both. INTERVENTIONS: Practices were randomized to receive either the intervention for hyperlipidaemia or for hypertension; practices acted as control for the intervention not received. Specialist nurses arranged a schedule of visits with general practitioners and general practice nurses, reminding them of diabetes protocols and clinical targets. They provided educational materials and protocols used in secondary care for nurse and doctor interventions including stepping up pharmacotherapy when necessary. Practices received a list of patients in their practice who were poorly controlled at their last annual review; new and recalled patients were targeted. OUTCOME MEASURES: At subsequent annual review, blood pressure and total cholesterol values were obtained from the Salford electronic diabetes register for patients from participating practices. RESULTS: Overall, specialist nurse-led educational outreach to primary care was associated with no improvement in patients achieving target after 1 year-odds ratio (OR): 1.03 (95% CI 0.95-1.11; P = 0.52). Similar results were achieved with hyperlipidaemia OR: 1.04 (95% CI 0.88-1.23; P = 0.62) and hypertension OR: 1.01 (95% CI 0.80-1.27; P = 0.93). CONCLUSION: This study provides evidence that the use of specialist nurses to perform educational outreach to improve target adherence to patients with diabetes in primary care is not effective.     

Systematic Review of Hypertension and Diabetes Burden,Risk Factors,and Interventions for Prevention and Control in Malawi: The NCD BRITE Consortium

Recent studies have found an increasing burden of noncommunicable diseases in sub-Saharan Africa. A compressive search of PubMed, Medline, EMBASE, and the World Health Organization Global Health Library databases was undertaken to identify studies reporting on the prevalence, risk factors, and interventions for hypertension and diabetes in Malawi. The findings from 23 included studies revealed a high burden of hypertension and diabetes in Malawi, with estimates ranging from 15.8% to 32.9% and from 2.4% to 5.6%, respectively. Associated risk factors included old age, tobacco smoking, excessive alcohol consumption, obesity, physical inactivity, high salt and sugar intake, low fruit and vegetable intake, high body mass index, and high waist-to-hip ratio. Certain antiretroviral therapy regimens were also associated with increased diabetes and hypertension risk in human immunodeficiency virus patient populations. Nationwide, the quality of clinical care was generally limited and demonstrated a need for innovative and targeted interventions to prevent, control, and treat noncommunicable diseases in Malawi.     

Hypertension management research priorities from patients,caregivers, and healthcare providers: A report from the Hypertension Canada Priority Setting Partnership Group

Patient‐ and stakeholder‐oriented research is vital to improving the relevance of research. The authors aimed to identify the 10 most important research priorities of patients, caregivers, and healthcare providers (family physicians, nurses, nurse practitioners, pharmacists, and dietitians) for hypertension management. Using the James Lind Alliance approach, a national web‐based survey asked patients, caregivers, and care providers to submit their unanswered questions on hypertension management. Questions already answered from randomized controlled trial evidence were removed. A priority setting process of patient, caregiver, and healthcare providers then ranked the final top 10 research priorities in an in‐person meeting. There were 386 respondents who submitted 598 questions after exclusions. Of the respondents, 78% were patients or caregivers, 29% lived in rural areas, 78% were aged 50 to 80 years, and 75% were women. The 598 questions were distilled to 42 unique questions and from this list, the top 10 research questions prioritized included determining the combinations of healthy lifestyle modifications to reduce the need for antihypertensive medications, stress management interventions, evaluating treatment strategies based on out‐of‐office blood pressure compared with conventional (office) blood pressure, education tools and technologies to improve patient motivation and health behavior change, management strategies for ethnic groups, evaluating natural and alternative treatments, and the optimal role of different healthcare providers and caregivers in supporting patients with hypertension. These priorities can be used to guide clinicians, researchers, and funding bodies on areas that are a high priority for hypertension management research for patients, caregivers, and healthcare providers. This also highlights priority areas for improved knowledge translation and delivering patient‐centered care.     

Cardiovascular risk factor control in communities--update from the ASH Carolinas-Georgia Chapter, the Hypertension Initiative, and the Community Physicians' Network

The prevalence of hypertension dictates that blood pressure must be managed effectively in primary care. The American Society of Hypertension (ASH) regional chapters and clinical hypertension specialists represent a positive response by ASH to the growing problems of hypertension and metabolic syndrome-related risks and disease. To have a significant public health effect, the impact of clinical hypertension specialists must be leveraged. Key activities in the community include educating other providers locally, delivering care for complex referral patients, and fostering growth of a practice network with a central database in collaboration with academic partners. The database supports practice audit and feedback reports to enhance quality improvement, identify continuing medical education topics, and facilitate clinical trials to test new therapeutic and best-practice approaches to risk factor management. The ASH regional chapters serve as a forum for community and academic hypertension specialists to collaborate with like-minded individuals and organizations. The collaboration among the ASH Carolinas-Georgia chapter, the Hypertension Initiative, and the Community Physicians' Network provides a model for other ASH chapters and health delivery groups to partner in delivering continuing medical education programs focused on cardiovascular risk factor management, recruiting practices into the network, and developing and maintaining a centralized patient database. Evidence suggests that this collaboration is facilitating application of evidence-based medicine and risk factor control.     

Telepharmacy for the management of cardiovascular patients in the community

Telepharmacy is devised to provide pharmacy operations and patient care at a distance and to expand access to healthcare, enhance patients’ safety and improve patient outcomes. A variety of technologies, models of care and interventions are used to develop and provide telepharmacy services, serving diversified populations with different pathological conditions, including cardiovascular diseases. Unfortunately, very few randomized controlled studies have evaluated the clinical efficacy of the implementation of telepharmacy services in the management of various cardiovascular conditions, with the strongest evidence being limited to telemonitoring studies in the areas of hypertension and diabetes. Although the clinical efficacy of telepharmacy, and its cost effectiveness, are far from being fully proved, the inclusion of telepharmacy services in healthcare models may offer the unique opportunity to increase access to screening and improve care of cardiovascular conditions.     

Treatment of hypertension in patients with comorbidities: Results from the study of hypertensive prescribing practices (SHyPP)

Approximately 50 million people have hypertension. Many agents with differing efficacy, side effects, dosing schedules, and costs are available to treat hypertension. Joint National Committee (JNC) guidelines attempt to simplify this decision by recommending specific agents based on special considerations such as comorbidities. The objective of this study was to survey primary care physicians’ antihypertensive prescribing practices and their treatment recommendations for patients with comorbidities. A direct mail survey was sent to a national random sample of 500 office-based primary care internists, family practitioners, and general practitioners. There were no significant differences between initial treatment recommendations at the time of the survey and those recommended before the survey. However, there were several therapeutic classes whose reported utilization for specific comorbidities significantly changed over 18 months. Angiotensin converting enzyme (ACE) inhibitors reportedly increased in patients with congestive heart failure and diabetes. In addition, the reported use of selective β-blockers increased for patients with a history of myocardial infarction. Physicians did not follow JNC recommendations when initiating treatment in black patients, older patients, or those with mild renal failure. Younger physicians were more likely than older physicians to select agents consistent with guideline recommendations. Physicians did not adhere to JNC guidelines when initiating treatment in patients with comorbidities; however, more physicians are prescribing recommended agents today as compared to 18 months ago. Younger physicians were more likely to prescribe agents consistent with the guidelines. More direct efforts are needed to ensure awareness and compliance with these guidelines.     

Primary prevention of cardiovascular disease: managing hypertension and hyperlipidaemia

Cardiovascular medicine has a sound evidence base upon which health professionals can base their interventions to modify risk among the British public. For primary prevention of cardiovascular disease, however, while there is considerable evidence on what to do, data are limited on how the evidence should be implemented in practice. The challenge will be to learn by experience which interventions directed at reducing blood pressure and lipids levels work best in different settings. There is a need to structure care to identify individuals who are at risk. Current targets are explicit and achievable for both hypertension and lipids. Effective treatment is likely to require multiple drug treatment.
