[Implementation of the HEARTS Initiative in Argentina: initial resultsImplementação da Iniciativa HEARTS na Argentina: primeiros resultados]. / Implementación de la Iniciativa HEARTS en Argentina: primeros resultados.

Cardiovascular diseases are the leading cause of mortality and morbidity in the Region of the Americas, and hypertension is one of the main risk factors. In 2018, Argentina began implementing the HEARTS Initiative in five primary health care centers, through the National Plan for the Prevention and Control of Arterial Hypertension. This study presents the impact its implementation has had on the indicators of effective coverage, treatment, combination therapy, and control. The HEARTS Initiative has multiple components; these include training health teams, reassigning tasks based on the transfer of clinical competencies, providing automatic and clinically validated blood pressure measurement devices, and using a single standardized treatment protocol. A longitudinal data model (generalized estimating equation analysis) was used, and the information from the five health centers was grouped using weighted averages according to the size of the population under coverage. Analysis of the results was stratified into two time periods delimited by the imposition of restrictions due to COVID-19. During the first period of 18 months, significant improvement was observed in treatment (5.9%; p<0.01) and combination therapy (13.4%; p<0.01), with no significant change in coverage (8.4%; p=0.87) and with a paradoxical decrease in control (-3.3%; p=0.02). When the period of restrictions was compared to the previous period, a generalized reduction was observed in all indicators, particularly coverage (-23.6%; p<0.01) and control (-12.5%; p<0.01). However, treatment and combination therapy levels remained above baseline values (1.7%; p<0.01 and 5.4%; p<0.01, respectively).

As doenças cardiovasculares são a principal causa de morbimortalidade, e a hipertensão, seu principal fator de risco. Em 2018, a Argentina começou a implementar a Iniciativa HEARTS em 5 centros de atenção primária à saúde por meio do Plano Nacional de Prevenção e Controle da Hipertensão Arterial. Este estudo apresenta o impacto de sua implementação nos indicadores de cobertura efetiva, tratamento, tratamento combinado e controle. A Iniciativa HEARTS inclui vários componentes. Entre eles, se destacam a capacitação das equipes de saúde, a reorganização das tarefas com base na transferência de competências clínicas, a disponibilização de aparelhos automáticos e clinicamente validados para aferição da pressão arterial e a utilização de um único protocolo padronizado de tratamento. Foi utilizado um modelo de equações de estimativas generalizadas para a análise de dados longitudinais, e as informações dos 5 centros de saúde foram agrupadas por meio de médias ponderadas de acordo com o tamanho da população coberta. A análise dos resultados foi estratificada em dois períodos de tempo delimitados pela irrupção das restrições em virtude da COVID-19. Durante os primeiros 18 meses, houve melhora significativa no tratamento (5,9%; p<0,01) e no tratamento combinado (13,4%; p<0,01), sem mudança significativa na cobertura (8,4%; p=0,87) e com uma diminuição paradoxal no controle (−3,3%; p=0,02). Durante as restrições e em relação ao período anterior, verificou-se redução generalizada em todos os indicadores, principalmente na cobertura (−23,6%; p<0,01) e no controle (−12,5%; p<0,01). No entanto, os níveis de tratamento e tratamento combinado persistiram acima dos valores basais (1,7%; p<0,01 e 5,4%; p<0,01, respectivamente).

Hypertension in Guatemala's Public Primary Care System: A Needs Assessment Using the Health System Building Blocks Framework.

BACKGROUND: Uncontrolled hypertension represents a substantial and growing burden in Guatemala and other low and middle-income countries. As a part of the formative phase of an implementation research study, we conducted a needs assessment to define short- and long-term needs and opportunities for hypertension services within the public health system. METHODS: We conducted a multi-method, multi-level assessment of needs related to hypertension within Guatemala's public system using the World Health Organization's health system building blocks framework. We conducted semi-structured interviews with stakeholders at national (n = 17), departmental (n = 7), district (n = 25), and community (n = 30) levels and focus groups with patients (3) and frontline auxiliary nurses (3). We visited and captured data about infrastructure, accessibility, human resources, reporting, medications and supplies at 124 health posts and 53 health centers in five departments of Guatemala. We conducted a thematic analysis of transcribed interviews and focus group discussions supported by matrix analysis. We summarized quantitative data observed during visits to health posts and centers. RESULTS: Major challenges for hypertension service delivery included: gaps in infrastructure, insufficient staffing and high turnover, limited training, inconsistent supply of medications, lack of reporting, low prioritization of hypertension, and a low level of funding in the public health system overall. Key opportunities included: prior experience caring for patients with chronic conditions, eagerness from providers to learn, and interest from patients to be involved in managing their health. The 5 departments differ in population served per health facility, accessibility, and staffing. All but 7 health posts had basic infrastructure in place. Enalapril was available in 74% of health posts whereas hydrochlorothiazide was available in only 1 of the 124 health posts. With the exception of one department, over 90% of health posts had a blood pressure monitor. CONCLUSIONS: This multi-level multi-method needs assessment using the building blocks framework highlights contextual factors in Guatemala's public health system that have been important in informing the implementation of a hypertension control trial. Long-term needs that are not addressed within the scope of this study will be important to address to enable sustained implementation and scale-up of the hypertension control approach.

Development of physical activity and food built environment quality indicators for chronic diseases in Argentina.

Although obesity and non-communicable disease (NCD) prevention efforts to-date have focused mainly on individual level factors, the social and physical environments in which people live are now widely recognized as important social determinants of health. Obesogenic environments promote higher dietary energy intakes and sedentary behaviors, thus contributing to the obesity/NCD burden. To develop quality indicators (QIs) for measuring food and physical activity (PA)-built environments in municipalities. A literature review was conducted. Based on the best practices identified from this review, a draft set of candidate QI was retrieved. The initial 67 QIs were then evaluated by a modified Delphi panel of multidisciplinary health professionals (n = 40) to determine their relevance, validity, and feasibility in 3 rounds of voting and threaded discussion using a modified RAND/University of California, Los Angeles Appropriateness Methodology. Response rate for the panel was 89.4%. All final 42 QIs were rated as highly relevant, valid, and feasible (median rating ≥ 7 on a 1-9 scale), with no significant disagreement. The final QI set addresses for the PA domain: (i) promotion of PA; and (ii) improvements in the environment to strengthen the practice of PA; and for Food environment domain: (i) promotion of healthy eating; (ii) access to healthy foods; and (iii) promotion of responsible advertising. We generated a set of indicators to evaluate the PA and food built environment, which can be adapted for use in Latin American and other low- and middle-income countries.

The built environment has a considerable effect on health indicators such as physical activity, eating behavior, and community. There is considerable research evidence demonstrating a direct relationship between our built environments and our health. In Argentina, the Healthy Municipalities and Communities Program focuses in health promotion interventions. It was developed to seek collaboration among community members, local government authorities and other stakeholders in order to improve quality of life. However, up to date, there has not been a homogenous measure to evaluate how well a particular locality or a whole municipality supports the health and wellbeing its residents. The proposed study aims to develop a set of local valid and common measures in order to evaluate what is happening within a particular municipality. A designated group of local experts will select a set of final measures trough out an iterative multistage process in order to combine opinion into group consensus. We will ask the panel to rate, discuss and re-rate the proposed measures (based on the existing evidence). This will study provide an evaluative tool to inform policy making and program implementation, and to guide programs and initiatives aimed at combating obesogenic environments in municipalities and communities.

[Health impact assessment of the Program Healthy Centers in the Autonomous City of Buenos Aires, ArgentinaAvaliação do impacto na saúde do Programa Estações Saudáveis na Cidade Autônoma de Buenos Aires, Argentina]. / Evaluación del impacto sanitario del Programa Estaciones Saludables en la Ciudad Autónoma de Buenos Aires, Argentina.

OBJECTIVE: To explore the motivations and expectations of the users of the Program for Healthy Centers in the Autonomous City of Buenos Aires and to evaluate its potential health impact. METHODS: In-depth interviews were conducted (n = 34) and a self-administered survey was sent to users of the program (n = 605). An epidemiological model was developed to estimate the impact of the program on cardiovascular events (CVE) and disability-adjusted life years (DALYs). RESULTS: The main motivating factors for using the healthy centers were geographic and economic accessibility (free services) and satisfaction with the care received. 14.4% (95% CI, 10.3-18.5%) of hypertensive users and 24.8% (95% CI, 17.6-32.0%) of diabetic users reported having learned of their altered values in the healthy center. More than half of the respondents reported some improvement in their knowledge about the benefits of physical activity and healthy eating; this was more frequent among those who were younger, of lower educational level, users of the public health system, users of a healthy center in the South zone and those who had a cardiometabolic risk factor (p<0.05). It was estimated that the healthy centers would prevent 12.5 cardiovascular and cerebrovascular events per year in the assisted population (4.75 events/100 000) and 47.75 DALYs due to these causes. CONCLUSIONS: The healthy centers are a favorable space for the implementation of health promotion and prevention actions, contributing to the detection of and facilitating the monitoring of risk factors, with a potential to prevent cardiovascular events and its consequences.

OBJETIVO: Explorar as motivações e expectativas dos usuários do Programa Estações Saudáveis na Cidade Autônoma de Buenos Aires e avaliar seu impacto potencial na saúde. MÉTODOS: Foram realizadas entrevistas em profundidade (n = 34) e uma pesquisa auto-administrada (n = 605) a usuários do programa. Um modelo epidemiológico foi desenvolvido para estimar o impacto do programa em eventos cardiovasculares e anos de vida ajustados por incapacidade (DALY). RESULTADOS: Os principais fatores motivadores para o uso do estações saudáveis foram a acessibilidade geográfica, econômica (serviços gratuitos) e a satisfação com o atendimento recebido. 14,4% (intervalo de confiança de 95% [IC95%] 10,3-18,5%) de usuários hipertensos e 24,8% (IC95% 17,6-32,0%) dos diabéticos relataram ter aprendido sobre seus valores alterados na estação saudável. Mais da metade dos entrevistados relataram alguma melhora no conhecimento sobre os benefícios da atividade física e da alimentação saudável, com maior freqüência entre os mais jovens, de menor escolaridade, usuários do sistema público de saúde, usuários de estações saudáveis na zona sul e aqueles que apresentaram algum fator de risco cardiometabólico (p<0,05). Estimou-se que, devido à existência de estações saudáveis, 12,5 eventos cardiovasculares e cerebrovasculares por ano seriam evitados na população atendida (4,75 eventos/100 000) e 47,75 DALY por essas causas. CONCLUSÕES: As estações saudáveis são um espaço propício para a implementação de ações de promoção e prevenção da saúde, contribuindo para a detecção e facilitação do monitoramento dos fatores de risco, com potencial para prevenir os eventos cardiovasculares e suas consequências.

Effect of a Community Health Worker-Led Multicomponent Intervention on Blood Pressure Control in Low-Income Patients in Argentina: A Randomized Clinical Trial.

Importance: Despite extensive knowledge of hypertension treatment, the prevalence of uncontrolled hypertension is high and increasing in low- and middle-income countries. Objective: To test whether a community health worker-led multicomponent intervention would improve blood pressure (BP) control among low-income patients with hypertension. Design, Setting, and Participants: A cluster randomized trial was conducted in 18 centers for primary health care within a national public system providing free medications and health care to uninsured patients in Argentina. A total of 1432 low-income adult patients with uncontrolled hypertension were recruited between June 2013 and April 2015 and followed up to October 2016. Interventions: Nine centers (743 patients) were randomized to the multicomponent intervention, which included a community health worker-led home intervention (health coaching, home BP monitoring, and BP audit and feedback), a physician intervention, and a text-messaging intervention over 18 months. Nine centers (689 patients) were randomized to usual care. Main Outcomes and Measures: The coprimary outcomes were the differences in systolic and diastolic BP changes from baseline to the end of follow-up of patients with hypertension. Secondary outcomes included the proportion of patients with controlled hypertension (BP <140/90 mm Hg). Three BP measurements were obtained at each of 2 baseline and 2 termination visits using a standard protocol, the means of which were used for analyses. Results: Of 1432 participants (mean age, 55.8 years [SD, 13.3]; 772 women [53.0%]), 1357 (94.8%) completed the trial. Baseline mean systolic BP was 151.7 mm Hg for the intervention group and 149.8 mm Hg for the usual care group; the mean diastolic BP was 92.2 mm Hg for the intervention group and 90.1 mm Hg for the usual care group. Systolic BP reduction from baseline to month 18 was 19.3 mm Hg (95% CI, 17.9-20.8 mm Hg) for the intervention group and 12.7 mm Hg (95% CI, 11.3-14.2 mm Hg) for the usual care group; the difference in the reduction was 6.6 mm Hg (95% CI, 4.6-8.6; P < .001). Diastolic BP decreased by 12.2 mm Hg (95% CI, 11.2-13.2 mm Hg) in the intervention group and 6.9 mm Hg (95% CI, 5.9-7.8 mm Hg) in the control group; the difference in the reduction was 5.4 mm Hg (95% CI, 4.0-6.8 mm Hg; P < .001). The proportion of patients with controlled hypertension increased from 17.0% at baseline to 72.9% at 18 months in the intervention group and from 17.6% to 52.2% in the usual care group; the difference in the increase was 20.6% (95% CI, 15.4%-25.9%; P < .001). No adverse events were reported. Conclusions and Relevance: Low-income patients in Argentina with uncontrolled hypertension who participated in a community health worker-led multicomponent intervention experienced a greater decrease in systolic and diastolic BP than did patients who received usual care over 18 months. Further research is needed to assess generalizability and cost-effectiveness of this intervention and to understand which components may have contributed most to the outcome.

Assessing the implementation of a multi-component hypertension program in a Guatemalan under-resourced dynamic context: an application of the RE-AIM/PRISM extension for sustainability and health equity.

BACKGROUND: The COVID-19 pandemic necessitated rapid changes in healthcare delivery in Guatemala's public primary care settings. A new hypertension program, implemented as part of a type 2 hybrid trial since 2019, exemplifies an implementation effort amidst a changing context in an under-resourced setting. We assessed the implementation of an evidence-based intervention (EBI; protocol-based hypertension treatment) and one of its main implementation strategies (team-based collaborative care), raising implications for health equity and sustainability. We present innovative application of systems thinking visuals. METHODS: Conducting a convergent mixed methods analysis, we assessed implementation in response to contextual changes across five Ministry of Health (MoH) districts at the pandemic's onset. Utilizing quantitative programmatic data and qualitative interviews with stakeholders (n=18; health providers, administrators, study staff), we evaluated dimensions of "Reach, Effectiveness, Adoption, Implementation and Maintenance," RE-AIM (Reach, Implementation delivery + adaptations), and "Practical Robust Implementation and Sustainability Model," PRISM (Organizational perspective on the EBI, Fit, Implementation and sustainability infrastructure) frameworks. We assessed representativeness by comparing participants to census data. To assess implementation delivery, we built behavior-over-time (BOT) graphs with quantitative programmatic data (July 2019-July 2021). To assess adaptations and contextual changes, we performed matrix-based thematic qualitative analysis. We converged quantitative implementation delivery data + qualitative adaptations data in joint displays. Finally, we analyzed qualitative and quantitative results across RE-AIM/PRISM and health districts to identify equity and sustainability considerations. RESULTS: Contextual factors that facilitated program delivery included the perception that the EBI was beneficial, program champions, and staff communication. Key barriers to implementation delivery included competition with other primary care activities and limited implementation infrastructure (e.g., equipment, medications). Contextual changes related to COVID-19 hindered implementation delivery, threatened sustainability, and may have exacerbated inequities. However, adaptations that were planned enhanced implementation delivery and may have supported improved equity and sustainability. CONCLUSIONS: Recognition of an EBI's benefits and program champions are important for supporting initial uptake. The ability to plan adaptations amid rapid contextual changes has potential advantages for sustainability and equitable delivery. Systems thinking tools and mixed methods approaches may shed light on the relations between context, adaptations, and equitable and sustainable implementation. TRIAL REGISTRATION: NCT03504124.

Implementing integrated hypertension and diabetes management using the World Health Organization's HEARTS model: protocol for a pilot study in the Guatemalan national primary care system.

BACKGROUND: The HEARTS technical package was developed by the World Health Organization to address the implementation gap in cardiovascular disease prevention in low- and middle-income countries. Guatemala is a middle-income country that is currently implementing HEARTS. National authorities in Guatemala are interested in exploring how hypertension and diabetes management can be integrated in HEARTS implementation. The objective of this study is to conduct a feasibility and acceptability pilot trial of integrated hypertension and diabetes management based on HEARTS in the publicly funded primary care system in Guatemala. METHODS: A single-arm pilot trial for 6 months will be carried out in 11 Ministry of Health primary care facilities starting in September 2023. A planned sample of 100 adult patients diagnosed with diabetes (n = 45), hypertension (n = 45), or both (n = 10) will be enrolled. The intervention will consist of HEARTS-aligned components: Training health workers on healthy-lifestyle counseling and evidence-based treatment protocols, strengthening access to medications and diagnostics, training on risk-based cardiovascular disease management, team-based care and task sharing, and systems monitoring and feedback, including implementation of a facility-based electronic monitoring tool at the individual level. Co-primary outcomes of feasibility and acceptability will be assessed using an explanatory sequential mixed-methods design. Secondary outcomes include clinical effectiveness (treatment with medication, glycemic control, and blood pressure control), key implementation outcomes (adoption, fidelity, usability, and sustainability), and patient-reported outcome measures (diabetes distress, disability, and treatment burden). Using an implementation mapping approach, a Technical Advisory Committee will develop implementation strategies for subsequent scale-up planning. DISCUSSION: This trial will produce evidence on implementing HEARTS-aligned hypertension and diabetes care in the MOH primary care system in Guatemala. Results also will inform future HEARTS projects in Guatemala and other low- and middle-income countries. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT06080451. The trial was prospectively registered on October 12, 2023.

Effectiveness of peer mentoring and self-monitoring to improve blood pressure control in a vulnerable population in Argentina: Pragmatic randomized open-label controlled trial.

OBJECTIVE: To evaluate the effectiveness of blood pressure (BP) self-monitoring and peer mentoring to improve the control of hypertension in clinical practice in primary care centers (PCCs) located in low-resource settings in Argentina. METHODS: An individual randomized controlled trial was carried out to test two different approaches based on behavioral interventions in PCCs in Argentina. Hypertensive adults were randomly assigned to one of three arms: BP self-monitoring, peer mentoring, and usual care. The primary outcome was the change in BP values from baseline to the end of follow-up at 3 months. A qualitative approach of participants' experiences of the peer mentoring arm was also conducted. RESULTS: A total of 442 participants with hypertension were included in the study. Self-monitoring and peer mentoring interventions did not show a significant difference in BP control compared to usual care. However, this trial showed an improvement regarding antihypertensive medication adherence among those assigned to the peer mentoring intervention compared to the control at the end of follow-up (p = 0.031). DISCUSSION: Self-monitoring and peer mentoring interventions did not demonstrate to be effective in BP control compared to usual care. Implementing a peer support strategy was demonstrated to be feasible and effective in improving medication adherence in this population.

Assessing the implementation of a multi-component hypertension program in a Guatemalan under-resourced dynamic context: An application of the RE-AIM/PRISM extension for sustainability and health equity.

Background: The COVID-19 pandemic necessitated rapid changes in the delivery of care across public primary care settings in rural Guatemala in 2020. In response, a hypertension program implemented within the public primary care system required multiple adaptations, providing an illustrative example of dynamic implementation amidst changing context in an under-resourced setting. This study describes the evolvability of an evidence-based intervention (EBI; protocol-based hypertension treatment) and one of its main implementation strategies (team-based collaborative care) during the COVID-19 pandemic and discusses implications for health equity and sustainability. Methods: This convergent mixed methods analysis assessed implementation across five Ministry of Health districts during the initial phase of the pandemic. Qualitative and quantitative data were collected, analyzed, and integrated, informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation Maintenance) Framework's extension for sustainability, and its contextual enhancement, PRISM (Pragmatic, Robust, Implementation and Sustainability Model). For RE-AIM, we focused on the "Implementation" domain, operationalizing it qualitatively as continued delivery and adaptations to the EBI and implementation strategy, and quantitatively as the extent of delivery over time. We conducted 18 in-depth interviews with health providers / administrators (n=8) and study staff (n=10) and performed a matrix-based thematic-analysis. Qualitative results informed the selection of quantitative implementation summarized as behavior over time graphs. Quantitative implementation data and illustrative quotes are presented as joint displays. Results: In relation to implementation, several organic adaptations hindered delivery, threatened sustainability, and may have exacerbated health inequities. Planned adaptations enhanced program delivery and may have supported improved equity and sustainability. Salient PRISM factors that influenced implementation included "Organizational perspective of the EBI", "Fit" and "Implementation and sustainability infrastructure". Facilitators to continued delivery included the perception that the EBI is beneficial, program champions, and healthcare team organization. Barriers included the perception that the EBI is complicated, competition with other primary care activities, and temporary suspension of services due to COVID-19. Conclusions: Multi-level contextual changes led to numerous adaptations of the EBI and implementation strategy. Systems thinking approaches may shed light on how a program's sustainability and its equitable delivery are influenced by adaptations over time in response to dynamic, multi-level contextual factors. Trial registration: NCT03504124.

Quality improvement intervention to increase colorectal cancer screening at the primary care setting: a cluster-randomised controlled trial.

BACKGROUND: Approximately 81% of deaths in Argentina are from chronic non-communicable diseases and 21% caused by cancer. Colorectal cancer (CRC) is the second most frequent cancer in Argentina. Even though CRC screening has been recommended for adults from 50 to 75 years old by using a faecal immunochemical test (FIT) annually, screening rates remain below 20% in the country. METHODS: We conducted an 18-month, two-arm, pragmatic cluster-randomised controlled trial evaluating the effect of a quality improvement intervention, based on the Plan-Do-Study-Act cycles, considering barriers and catalysts to articulate theory and practice, to increase CRC screening rates using FITs at primary care level. The study involved ten public primary health centres in Mendoza province, Argentina. The primary outcome measure was the rate of effective CRC screening. Secondary outcomes were the rate of participants with a positive FIT, tests with invalid results and the rate of participants referred for colonoscopy. RESULTS: Screening was effective in 75% of the participants in the intervention arm vs 54.2% in the control arm, OR 2.5 (95% CI 1.4 to 4.4, p=0.001). These results remained unchanged after adjusting for individual demographic and socioeconomic characteristics. Regarding secondary outcomes, the overall prevalence of positive tests was 17.7% (21.1% in the control arm and 14.7% in the intervention arm, p=0.3648). The overall proportion of participants with inadequate test results was 5.2% (4.9% in the control arm vs 5.5% in the intervention arm, p=0.8516). All the participants with positive tests were referred for colonoscopy in both groups. CONCLUSIONS: An intervention based on quality improvement strategies proved to be highly successful in increasing effective CRC screening in Argentina's primary care setting within the public healthcare system. TRIAL REGISTRATION NUMBER: NCT04293315.

Implementation outcomes and strategies for delivering evidence-based hypertension interventions in lower-middle-income countries: Evidence from a multi-country consortium for hypertension control.

Guidance on contextually tailored implementation strategies for the prevention, treatment, and control of hypertension is limited in lower-middle income countries (Lower-MIC). To address this limitation, we compiled implementation strategies and accompanying outcomes of evidence-based hypertension interventions currently being implemented in five Lower-MIC. The Global Research on Implementation and Translation Science (GRIT) Coordinating Center (CC) (GRIT-CC) engaged its global network sites at Ghana, Guatemala, India, Kenya, and Vietnam. Purposively sampled implementation science experts completed an electronic survey assessing implementation outcomes, in addition to implementation strategies used in their ongoing hypertension interventions from among 73 strategies within the Expert Recommendations for Implementing Change (ERIC). Experts rated the strategies based on highest priority to their interventions. We analyzed the data by sorting implementation strategies utilized by sites into one of the nine domains in ERIC and summarized the data using frequencies, proportions, and means. Seventeen implementation experts (52.9% men) participated in the exercise. Of Proctor's implementation outcomes identified across sites, all outcomes except for appropriateness were broadly assessed by three or more countries. Overall, 59 out of 73 (81%) strategies were being utilized in the five countries. The highest priority implementation strategies utilized across all five countries focused on evaluative and iterative strategies (e.g., identification of context specific barriers and facilitators) to delivery of patient- and community-level interventions, while the lowest priority was use of financial and infrastructure change strategies. More capacity building strategies (developing stakeholder interrelationships, training and educating stakeholders, and supporting clinicians) were incorporated into interventions implemented in India and Vietnam than Ghana, Kenya, and Guatemala. Although robust implementation strategies are being used in Lower -MICs, there is minimum use of financial and infrastructure change strategies. Our study contributes to the growing literature that demonstrates the use of Expert Recommendations for Implementing Change (ERIC) implementation strategies to deliver evidence-based hypertension interventions in Lower-MICs and will inform future cross-country data harmonization activities in resource-constrained settings.

The Use of 2 e-Learning Modalities for Diabetes Education Using Facebook in 2 Cities of Argentina During the COVID-19 Pandemic: Qualitative Study.

BACKGROUND: The COVID-19 pandemic and the confinement that was implemented in Argentina generated a need to implement innovative tools for the strengthening of diabetes care. Diabetes self-management education (DSME) is a core element of diabetes care; however, because of COVID-19 restrictions, in-person diabetes educational activities were suspended. Social networks have played an instrumental role in this context to provide DSME in 2 cities of Argentina and help persons with diabetes in their daily self-management. OBJECTIVE: The aim of this study is to evaluate 2 diabetes education modalities (synchronous and asynchronous) using the social media platform Facebook through the content of posts on diabetes educational sessions in 2 cities of Argentina during the COVID-19 pandemic. METHODS: In this qualitative study, we explored 2 modalities of e-learning (synchronous and asynchronous) for diabetes education that used the Facebook pages of public health institutions in Chaco and La Rioja, Argentina, in the context of confinement. Social media metrics and the content of the messages posted by users were analyzed. RESULTS: A total of 332 messages were analyzed. We found that in the asynchronous modality, there was a higher number of visualizations, while in the synchronous modality, there were more posts and interactions between educators and users. We also observed that the number of views increased when primary care clinics were incorporated as disseminators, sharing educational videos from the sessions via social media. Positive aspects were observed in the posts, consisting of messages of thanks and, to a lesser extent, reaffirmations, reflections or personal experiences, and consultations related to the subject treated. Another relevant finding was that the educator/moderator role had a greater presence in the synchronous modality, where posts were based on motivation for participation, help to resolve connectivity problems, and answers to specific user queries. CONCLUSIONS: Our findings show positive contributions of an educational intervention for diabetes care using the social media platform Facebook in the context of the COVID-19 pandemic. Although each modality (synchronous vs asynchronous) could have differential and particular advantages, we believe that these strategies have potential to be replicated and adapted to other contexts. However, more documented experiences are needed to explore their sustainability and long-term impact from the users' perspective.

Barriers to hypertension and diabetes management in primary health care in Argentina: qualitative research based on a behavioral economics approach.

Despite efforts to improve detection and treatment of adults with hypertension and diabetes in Argentina, many public healthcare system users remain undiagnosed or face barriers in managing these diseases. The purpose of this study is to identify health system, provider, and user-related factors that may hinder detection and treatment of hypertension and diabetes using a traditional and behavioral economics approach. We did qualitative research using in-depth semistructured interviews and focus groups with healthcare providers and adult users of Public Primary Care Clinics. Health system barriers included inadequate care accessibility; poor integration between primary care clinics and local hospitals; lack of resources; and gender bias and neglect of adult chronic disease. Healthcare provider-related barriers were inadequate training; lack of availability or reluctance to adopt Clinical Practice Guidelines; and lack of counseling prioritization. From a behavioral economics perspective, bottlenecks were related to inertia and a status quo, overconfidence, and optimism biases. User-related barriers for treatment adherence included lack of accurate information; resistance to adopt lifelong treatment; affordability; and medical advice mistrust. From a behavioral economics perspective, the most significant bottlenecks were overconfidence and optimism, limited attention, and present biases. Based on these findings, new interventions that aim to improve prevention and control of chronic conditions can be proposed. The study provides empirical evidence regarding the barriers and bottlenecks in managing chronic conditions in primary healthcare settings. Results may contribute to the design of behavioral interventions targeted towards healthcare provision for the affected population.

Perceptions and Acceptability of Text Messaging for Diabetes Care in Primary Care in Argentina: Exploratory Study.

BACKGROUND: Engagement in self-care behaviors that are essential to optimize diabetes care is challenging for many patients with diabetes. mHealth interventions have been shown to be effective in improving health care outcomes in diabetes. However, more research is needed on patient perceptions to support these interventions, especially in resource settings in low- and middle-income countries. OBJECTIVE: The goal of the research was to explore perceptions and acceptability of a short message service (SMS) text messaging intervention for diabetes care in underserved people with diabetes in Argentina. METHODS: A qualitative exploratory methodology was adopted as part of the evaluation of a program to strengthen diabetes services in primary care clinics located in low-resource settings. The diabetes program included a text messaging intervention for people with diabetes. A total of 24 semistructured telephone interviews were conducted with people with diabetes. RESULTS: Twenty-four middle-aged persons with diabetes were interviewed. Acceptability was considered adequate in terms of its actual use, frequency, and the role of texts as a reminder. We found that text messages could be a mediating device in the patient's learning processes. Also, being exposed to the texts seemed to help bring about changes in risk perception and care practices and to function as psychosocial support. Another relevant finding was the role of text messaging as a potential facilitator in diabetes care. In this sense, we observed a strong association between receiving text messages and having a better patient-physician relationship. Additionally, social barriers that affect diabetes care such as socioeconomic and psychosocial vulnerability were identified. CONCLUSIONS: Our findings show positive contributions of a text messaging intervention for the care of people with diabetes. We consider that an SMS strategy has potential to be replicated in other contexts. However, further studies are needed to explore its sustainability and long-term impact from the perspective of patients.

Implementación de la Iniciativa HEARTS en Argentina: primeros resultados / Implementation of the HEARTS Initiative in Argentina: initial results / Implementação da Iniciativa HEARTS na Argentina: primeiros resultados

RESUMEN Las enfermedades cardiovasculares son la principal causa de morbimortalidad, y la hipertensión es su principal factor de riesgo. En 2018, Argentina comenzó a implementar la Iniciativa HEARTS en 5 centros de atención primaria de salud a través del Plan Nacional de Prevención y Control de la Hipertensión Arterial. En este estudio se presenta el impacto de su implementación en los indicadores de cobertura efectiva, tratamiento, tratamiento combinado y control. La Iniciativa HEARTS incluye múltiples componentes; entre ellos se destacan la capacitación de los equipos de salud, la reorganización de las tareas basada en la transferencia de competencias clínicas, la provisión de dispositivos de medición de la presión arterial automáticos y clínicamente validados, y la utilización de un único protocolo de tratamiento estandarizado. Se utilizó un modelo de datos longitudinales del tipo ecuación de estimación generalizada, y se agrupó la información de los 5 centros de salud mediante promedios ponderados según el tamaño de la población bajo cobertura. El análisis de los resultados fue estratificado en dos períodos de tiempo delimitados por la irrupción de las restricciones debidas al COVID-19. Durante el primer período de 18 meses se observó una mejoría significativa en el tratamiento (5,9%; p<0,01) y el tratamiento combinado (13,4%; p<0,01), sin cambios significativos en la cobertura (8,4%; p=0,87) y con un descenso paradojal en el control (−3,3%; p=0,02). Durante las restricciones y respecto del período previo, se constató una reducción generalizada en todos los indicadores, principalmente en la cobertura (−23,6%; p<0,01) y el control (−12,5%; p<0,01). Sin embargo, los niveles de tratamiento y tratamiento combinado persistieron por encima de los valores basales (1,7%; p<0,01 y 5,4%; p<0,01, respectivamente).

ABSTRACT Cardiovascular diseases are the leading cause of mortality and morbidity in the Region of the Americas, and hypertension is one of the main risk factors. In 2018, Argentina began implementing the HEARTS Initiative in five primary health care centers, through the National Plan for the Prevention and Control of Arterial Hypertension. This study presents the impact its implementation has had on the indicators of effective coverage, treatment, combination therapy, and control. The HEARTS Initiative has multiple components; these include training health teams, reassigning tasks based on the transfer of clinical competencies, providing automatic and clinically validated blood pressure measurement devices, and using a single standardized treatment protocol. A longitudinal data model (generalized estimating equation analysis) was used, and the information from the five health centers was grouped using weighted averages according to the size of the population under coverage. Analysis of the results was stratified into two time periods delimited by the imposition of restrictions due to COVID-19. During the first period of 18 months, significant improvement was observed in treatment (5.9%; p<0.01) and combination therapy (13.4%; p<0.01), with no significant change in coverage (8.4%; p=0.87) and with a paradoxical decrease in control (−3.3%; p=0.02). When the period of restrictions was compared to the previous period, a generalized reduction was observed in all indicators, particularly coverage (−23.6%; p<0.01) and control (−12.5%; p<0.01). However, treatment and combination therapy levels remained above baseline values (1.7%; p<0.01 and 5.4%; p<0.01, respectively).

Effectiveness of an mHealth intervention to improve the cardiometabolic profile of people with prehypertension in low-resource urban settings in Latin America: a randomised controlled trial.

BACKGROUND: Poor diet and physical inactivity strongly affect the growing epidemic of cardiovascular disease worldwide. Mobile phone-based health interventions (mHealth) have been shown to help promote weight loss and increase physical activity and are an attractive approach for health-care systems with limited resources. We aimed to assess whether mHealth with advice for lifestyle improvements would reduce blood pressure, promote weight loss, and improve diet quality and physical activity in individuals with prehypertension living in low-resource urban settings in Latin America. METHODS: In this parallel-group, randomised controlled trial, we recruited individuals (aged 30-60 years) with systolic blood pressure between 120 and 139 mm Hg, diastolic blood pressure between 80 and 89 mm Hg, or both from health-care centres, workplaces, and community centres in low-resource urban settings in Argentina, Guatemala, and Peru. Participants were randomly assigned to receive either monthly motivational counselling calls and weekly personalised text messages to their mobile phones about diet quality and physical activity for 12 months, or usual care. Randomisation was stratified by country, and we applied minimisation by sex and age groups. Study personnel collecting and analysing data were masked to group assignment. The primary outcomes were mean between-group differences in the changes in systolic and diastolic blood pressure from baseline to 12 months in an intention-to-treat analysis of all participants who completed assessments at 12 months. Secondary outcome measures were changes in bodyweight, waist circumference, and self-reported target behaviours from baseline to 12 months. The trial is registered with ClinicalTrials.gov, number NCT01295216. FINDINGS: Between March 1, 2012, and Nov 30, 2012, we randomly assigned 637 participants to receive intervention (n=316) or usual care (n=321). 266 (84%) participants in the intervention group and 287 (89%) in the control group were assessed at 12 months. The intervention did not affect change in systolic blood pressure (mean net change -0·37 mm Hg [95% CI -2·15 to 1·40]; p=0·43) or diastolic blood pressure (0·01 mm Hg [-1·29 to 1·32]; p=0·99) compared with usual care. However, we noted a significant net reduction in bodyweight (-0·66 kg [-1·24 to -0·07]; p=0·04) and intake of high-fat and high-sugar foods (-0·75 [-1·30 to -0·20]; p=0·008) in the intervention group compared with the control group. In a prespecified subanalysis, we found that participants in the intervention group who received more than 75% of the calls (nine or more, from a maximum of 12) had a greater reduction of bodyweight (-4·85 [-8·21 to -1·48]) and waist circumference (-3·31 [-5·95 to -0·67]) than participants in the control group. Additionally, participants in the intervention group had an increase in the intake of fruits and vegetables and a decrease in diets high in sodium, fat, and simple sugars relative to participants in the control group. However, we found no changes in systolic blood pressure, diasatolic blood pressure, or physical activity in the group of participants who received more than 75% of the calls compared with the group who received less than 50% of the calls. INTERPRETATION: Our mHealth-based intervention did not result in a change in blood pressure that differed from usual care, but was associated with a small reduction in bodyweight and an improvement in some dietary habits. We noted a dose-response effect, which signals potential opportunities for larger effects from similar interventions in low-resource settings. More research is needed on mHealth, particularly among people who are poor and disproportionally affected by the cardiovascular disease epidemic and who need effective and affordable interventions to help bridge the equity gap in the management of cardiometabolic risk factors.

Challenges and opportunities for implementation of interventions to prevent and control CVD in low-resource settings: a report from CESCAS in Argentina.

In Argentina, cardiovascular diseases cause an estimated 100,000 deaths and more than 250,000 coronary heart disease and stroke events annually, at a cost of more than $1 billion international dollars. Despite progress in the implementation of several programs to combat noncommunicable diseases in Argentina over the past few years, most health resources are still dedicated to infectious diseases and maternal and child health. The Institute for Clinical Effectiveness and Health Policy, an independent academic institution affiliated with the University of Buenos Aires medical school, runs the South American Centre of Excellence in Cardiovascular Health (CESCAS), a center devoted to epidemiology, implementation, and policy research. At the CESCAS, there are 3 ongoing randomized clinical trials focused on implementation science: 1) a mobile health intervention, for preventing the progression of prehypertension in low-income, urban settings in Argentina, Guatemala, and Peru; 2) a comprehensive approach to preventing and controlling hypertension in low-resource settings in Argentina; and 3) an educational approach to improving physicians' effectiveness in the detection, treatment, and control of hypercholesterolemia and high cardiovascular disease risk in low-resource settings in Argentina. All of these trials involve the design and implementation of complex interventions for changing the behaviors of providers and patients. The rationale of each of the 3 studies, the design of the interventions, and the evaluation of processes and outcomes are described in this article, together with the barriers and enabling factors associated with implementation-research studies. There is a strong need in Argentina and all of Latin America for building the health-research capacity and infrastructure necessary for undertaking implementation studies that will translate evidence from research findings into improvements in health policy and practice with regard to cardiovascular diseases and their risk factors.

Behaviour change strategies for reducing blood pressure-related disease burden: findings from a global implementation research programme.

BACKGROUND: The Global Alliance for Chronic Diseases comprises the majority of the world's public research funding agencies. It is focussed on implementation research to tackle the burden of chronic diseases in low- and middle-income countries and amongst vulnerable populations in high-income countries. In its inaugural research call, 15 projects were funded, focussing on lowering blood pressure-related disease burden. In this study, we describe a reflexive mapping exercise to identify the behaviour change strategies undertaken in each of these projects. METHODS: Using the Behaviour Change Wheel framework, each team rated the capability, opportunity and motivation of the various actors who were integral to each project (e.g. community members, non-physician health workers and doctors in projects focussed on service delivery). Teams then mapped the interventions they were implementing and determined the principal policy categories in which those interventions were operating. Guidance was provided on the use of Behaviour Change Wheel to support consistency in responses across teams. Ratings were iteratively discussed and refined at several group meetings. RESULTS: There was marked variation in the perceived capabilities, opportunities and motivation of the various actors who were being targeted for behaviour change strategies. Despite this variation, there was a high degree of synergy in interventions functions with most teams utilising complex interventions involving education, training, enablement, environmental restructuring and persuasion oriented strategies. Similar policy categories were also targeted across teams particularly in the areas of guidelines, communication/marketing and service provision with few teams focussing on fiscal measures, regulation and legislation. CONCLUSIONS: The large variation in preparedness to change behaviour amongst the principal actors across these projects suggests that the interventions themselves will be variably taken up, despite the similarity in approaches taken. The findings highlight the importance of contextual factors in driving success and failure of research programmes. Forthcoming outcome and process evaluations from each project will build on this exploratory work and provide a greater understanding of factors that might influence scale-up of intervention strategies.

Avoidable hospitalizations for ambulatory care sensitive conditions as an indicator of primary health care effectiveness in Argentina.

Avoidable hospitalizations for ambulatory care sensitive conditions (AH-ACSCs) identify health problems that could be avoided by improving primary health care (PHC). On the basis of hospital discharges from Argentine public sector facilities, an expert panel convened to define a list of AH-ACSCs for children and adults. AH-ACSCs represented less than 30% of hospitalizations. Compared with country averages, poorer districts showed large differences in trends for adults but not for children. Despite that AH-ACSCs have demonstrated empirical validity to evaluate health system performance, its implementation to assess PHC in countries like Argentina, with pluralistic and fragmented health care systems, remains a big challenge.
