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.

Impact of COVID-19 on diabetes care: mixed methods study in an Indigenous area of Guatemala.

INTRODUCTION: SARS-CoV-2 has impacted globally the care of chronic diseases. However, direct evidence from certain vulnerable communities, such as Indigenous communities in Latin America, is missing. We use observational data from a health district that primarily serves people of Maya K'iche' ethnicity to examine the care of type 2 diabetes in Guatemala during the pandemic. METHODS: We used a parallel convergent mixed methods design. Quantitative data (n=142 individuals with diabetes) included glycated haemoglobin (HbA1c), blood pressure, body mass index and questionnaires on diabetes knowledge, self-care and diabetes distress. Quantitative data was collected at two points, at baseline and after COVID restrictions were lifted. For quantitative outcomes, we constructed multilevel mixed effects models with multiple imputation for missing data. Qualitative data included interviews with providers, supervisors and individuals living with diabetes (n=20). We conducted thematic framework analysis using an inductive approach. RESULTS: Quantitative data was collected between June 2019 and February 2021, with a median of 487 days between data collection points. HbA1c worsened +0.54% (95% CI, 0.14 to 0.94) and knowledge about diabetes decreased -3.54 points (95% CI, -4.56 to -2.51). Qualitatively, the most important impact of the pandemic was interruption of the regular timing of home visits and peer group meetings which were the standard of care. CONCLUSIONS: The deterioration of diabetes care was primarily attributed to the loss of regular contact with healthcare workers. The results emphasize the vulnerability of rural and Indigenous populations in Latin America to the suspension of chronic disease care.

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.

Explanatory models of hypertension in Guatemala: recognizing the perspectives of patients, family members, health care providers and administrators, and national-level health system stakeholders.

BACKGROUND: Uncontrolled hypertension is a major public health burden and the most common preventable risk factor for cardiovascular diseases in Guatemala and other low- and middle-income countries. Prior to an initial trial that evaluated a hypertension intervention in rural Guatemala, we collected qualitative information on the needs and knowledge gaps of hypertension care within Guatemala's public healthcare system. This analysis applied Kleinman's Explanatory Models of Illness to capture how patients, family members, community-, district-, and provincial-level health care providers and administrators, and national-level health system stakeholders understand hypertension.  METHODS: We conducted in-depth interviews with three types of participants: 1) national-level health system stakeholders (n = 17), 2) local health providers and administrators from district, and health post levels (25), and 3) patients and family members (19) in the departments of Sololá and Zacapa in Guatemala. All interviews were conducted in Spanish except for 6 Maya-Kaqchikel interviews. We also conducted focus group discussions with auxiliary nurses (3) and patients (3), one in Maya-Tz'utujil and the rest in Spanish. Through framework and matrix analysis, we compared understandings of hypertension by participant type using the Explanatory Model of Illness domains -etiology, symptoms, pathophysiology, course of illness, and treatment. RESULTS: Health providers and administrators, and patients described hypertension as an illness that spurs from emotional states like sadness, anger, and worry; is inherited and related to advanced age; and produces symptoms that include a weakened body, nerves, pain, and headaches. Patients expressed concerns about hypertension treatment's long-term consequences, despite trying to comply with treatment. Patients stated that they combine biomedical treatment (when available) with natural remedies (teas and plants). Health providers and administrators and family members stated that once patients feel better, they often disengage from treatment. National-level health system stakeholders referred to lifestyle factors as important causes, considered patients to typically be non-compliant, and identified budget limitations as a key barrier to hypertension care. The three groups of participants identified structural barriers to limited hypertension care (e.g., limited access to healthy food and unaffordability of medications). CONCLUSION: As understandings of hypertension vary between types of participants, it is important to describe their similarities and differences considering the role each has in the health system. Considering different perceptions of hypertension will enable better informed program planning and implementation efforts.

Monitoring Study Participants and Implementation with Phone Calls to Support Hypertension Control During the COVID-19 Pandemic: The Case of a Multicomponent Intervention Trial in Guatemala.

Background: The COVID-19 pandemic presents a challenge to health care for patients with chronic diseases, especially hypertension, because of the important association and increased risk of these patients with a severe presentation of COVID-19 disease. The Guatemalan Ministry of Health has been implementing a multi-component program aimed at improving hypertension control in rural communities since 2019 as a part of an intervention research cluster randomized trial. When the first cases of COVID-19 were reported (March 13, 2020) in Guatemala, our study paused all study field activities, and began monitoring participants through phone calls. The objective of this paper is to describe the approach used to monitor study participants during the COVID-19 pandemic and compare data obtained during phone calls for intervention and control group participants. Methods: We developed a cross-sectional study within the HyTREC (Hypertension Outcomes for T4 Research within Lower Middle-Income Countries) project 'Multicomponent Intervention to Improve Hypertension Control in Central America: Guatemala' in which phone calls were made to participants from both intervention and control groups to monitor measures important to the study: delivery of antihypertensive medications in both groups, receipt of coaching sessions and use of a home blood pressure monitor by intervention group participants, as well as reasons that they were not implemented. Results: Regarding the delivery of antihypertensive drugs by the MoH to participants, those in the intervention group had a higher level of medication delivery (73%) than the control group (51%), p<0.001. Of the total participants in the intervention group, 62% had received at least one health coaching session in the previous three months and 81% used a digital home blood pressure monitor at least twice a week. Intervention activities were lower than expected due to restricted public transportation on top of decreased availability of health providers. Conclusion: In Guatemala, specifically in rural settings, access to antihypertensive medications and health services during pandemic times was impaired and less than expected, even after accounting for the program's implementation activities and actions.

Implementation of a Diabetes Self-Management Education and Support Intervention in Rural Guatemala: A Mixed-Methods Evaluation Using the RE-AIM Framework.

INTRODUCTION: To address the global diabetes epidemic, lifestyle counseling on diet, physical activity, and weight loss is essential. This study assessed the implementation of a diabetes self-management education and support (DSMES) intervention using a mixed-methods evaluation framework. METHODS: We implemented a culturally adapted, home-based DSMES intervention in rural Indigenous Maya towns in Guatemala from 2018 through 2020. We used a pretest-posttest design and a mixed-methods evaluation approach guided by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Quantitative data included baseline characteristics, implementation metrics, effectiveness outcomes, and costs. Qualitative data consisted of semistructured interviews with 3 groups of stakeholders. RESULTS: Of 738 participants screened, 627 participants were enrolled, and 478 participants completed the study. Adjusted mean change in glycated hemoglobin A1c was -0.4% (95% CI, -0.6% to -0.3%; P < .001), change in systolic blood pressure was -5.0 mm Hg (95% CI, -6.4 to -3.7 mm Hg; P < .001), change in diastolic blood pressure was -2.6 mm Hg (95% CI, -3.4 to -1.9 mm Hg; P < .001), and change in body mass index was 0.5 (95% CI, 0.3 to 0.6; P < .001). We observed improvements in diabetes knowledge, distress, and most self-care activities. Key implementation factors included 1) recruitment barriers for men, 2) importance of patient-centered care, 3) role of research staff in catalyzing health worker involvement, 4) tradeoffs between home and telephone visits, and 5) sustainability challenges. CONCLUSION: A community health worker-led DSMES intervention was successfully implemented in the public health system in rural Guatemala and resulted in significant improvements in most clinical and psychometric outcomes. Scaling up sustainable DSMES in health systems in rural settings requires careful consideration of local barriers and facilitators.

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.

Shedding Light on the Free Radical Nature of Sulfonated Melanins.

Melanin, an important class of natural pigment found in the human body, has stood out as a promising bioelectronic material due to its rather unique collection of electrical properties and biocompatibility. Among the available melanin derivatives, the sulfonated form has proven to not only be able to produce homogeneous device quality thin films with excellent adhesion, even on hydrophobic surfaces, but also to act as an ion to electron transducing element. It has recently been shown that the transport physics (and dominant carrier generation) may be related to a semiquinone free radical species in these materials. Hence, a better understanding of the paramagnetic properties of sulfonated derivatives could shed light on their charge transport behavior and thus enable improvement in regard to use in bioelectronics. Motivated by this question, in this work, different sulfonated melanin derivatives were investigated by hydration-controlled, continuous-wave X-band electron paramagnetic resonance spectroscopy and electronic structure calculations. Our results show that sulfonated melanin behaves similarly to non-functionalized melanin, but demonstrates a less pronounced response to humidity vis-à-vis standard melanin. We thus speculate on the structural and charge transport behavior in light of these differences with a view to further engineering structure-property relationships.

Evaluating a multicomponent program to improve hypertension control in Guatemala: study protocol for an effectiveness-implementation cluster randomized trial.

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease (CVD). Despite advances in hypertension prevention and treatment, the proportion of patients who are aware, treated and controlled is low, particularly in low-income and middle-income countries (LMICs). We will evaluate an adapted version of a multilevel and multicomponent hypertension control program in Guatemala, previously proven effective and feasible in Argentina. The program components are: protocol-based hypertension treatment using a standardized algorithm; team-based collaborative care; health provider education; health coaching sessions; home blood pressure monitoring; blood pressure audit; and feedback. METHODS: Using a hybrid type 2 effectiveness-implementation design, we will evaluate clinical and implementation outcomes of the multicomponent program in Guatemala over an 18-month period. Through a cluster randomized trial, we will randomly assign 18 health districts to the intervention arm and 18 to enhanced usual care across five departments, enrolling 44 participants per health district and 1584 participants in total. The clinical outcomes are (1) the difference in the proportion of patients with controlled hypertension (< 130/80 mmHg) between the intervention and control groups at 18 months and (2) the net change in systolic and diastolic blood pressure from baseline to 18 months. The context-enhanced Reach, Efficacy, Adoption, Implementation, Maintenance (RE-AIM)/Practical Robust Implementation and Sustainability Model (PRISM) framework will guide the evaluation of the implementation at the level of the patient, provider, and health system. Using a mixed-methods approach, we will evaluate the following implementation outcomes: acceptability, adoption, feasibility, fidelity, adaptation, reach, sustainability, and cost-effectiveness. DISCUSSION: We will disseminate the study findings, and promote scale up and scale out of the program, if proven effective. This study will generate urgently needed data on effective, adoptable, and sustainable interventions and implementation strategies to improve hypertension control in Guatemala and other LMICs. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03504124. Registered on 20 April 2018.

Stakeholder Engagement in the Translation of a Hypertension Control Program to Guatemala's Public Primary Health Care System: Lessons Learned, Challenges, and Opportunities.

BACKGROUND: There is an urgent need to define appropriate intervention strategies to control blood pressure in low- and middle-income countries. In 2018, a program proven effective in Argentina was translated to Guatemala's public primary health care system in rural and primarily indigenous communities. OBJECTIVES: This paper describes the stakeholder engagement process used to adapt the program to the Guatemalan rural context prior to implementing a type II hybrid effectiveness-implementation trial and shares lessons learned. METHODS: We identified key differences in the 2 contexts that are relevant to translating the intervention to the Guatemalan context. Alongside interviews and focus group discussions, we conducted consultation workshops in July and August 2018, applying a participatory translation process involving patients, family members, community members, health care providers, and Ministry of Health officials. The process consisted of multiple meetings in Guatemala City, as well as meetings in each of the 5 departments where the study will be implemented, and 1 district per department. During the workshops, we presented the evidence-based experience from Argentina and then focused on the challenges and recommended solutions that the participants identified for each of the intervention's 6 components. The process concluded with a meeting in which the research team and Ministry of Health officials defined specific details of the intervention. RESULTS: The outcome of the process is an adapted approach appropriate to integrate into Guatemala's public primary health care system in the trial phase. The approach considers the challenges and recommended strategies for each of the 6 intervention components. CONCLUSIONS: We identified lessons learned, challenges, and opportunities during the adaptation process. Findings will inform ongoing stakeholder engagement during the study implementation and future scale-up and efforts to translate evidence-based hypertension control strategies to low- and middle-income countries globally.

Impact evaluation of a healthy lifestyle intervention to reduce cardiovascular disease risk in health centers in San José, Costa Rica and Chiapas, Mexico.

BACKGROUND: Previous healthy lifestyle interventions based on the Salud para Su Corazón curriculum for Latinos in the United States, and a pilot study in Guatemala, demonstrated improvements in patient knowledge, behavior, and clinical outcomes for adults with hypertension. This article describes the implementation of a healthy lifestyle group education intervention at the primary care health center level in the capital cities of Costa Rica and Chiapas, Mexico for patients with hypertension and/or type 2 diabetes and presents impact evaluation results. METHODS: Six group education sessions were offered to participants at intervention health centers from November 2011 to December 2012 and participants were followed up for 8 months. The study used a prospective, longitudinal, nonequivalent pretest-posttest comparison group design, and was conducted in parallel in the two countries. Cognitive and behavioral outcome measures were knowledge, self-efficacy, stage-of-change, dietary behavior and physical activity. Clinical outcomes were: body mass index, systolic and diastolic blood pressure, and fasting blood glucose. Group by time differences were assessed using generalized estimating equation models, and a dose-response analysis was conducted for the intervention group. RESULTS: The average number of group education sessions attended in Chiapas was 4 (SD: 2.2) and in Costa Rica, 1.8 (SD: 2.0). In both settings, participation in the study declined by 8-month follow-up. In Costa Rica, intervention group participants showed significant improvements in systolic and diastolic blood pressure and borderline significant improvement for fasting glucose, and significant improvement in the stages-of-change measure vs. the comparison group. In Chiapas, the intervention group showed significant improvement in the stages-of-change measure in relation to the comparison group. Significant improvements were not observed for knowledge, self-efficacy, dietary behavior or physical activity. In Chiapas only, a significant dose-response relationship was observed for systolic and diastolic blood pressure. CONCLUSION: Group education interventions at health centers have the potential to improve stage-of-change activation, and may also improve clinical outcomes. In the future, it will be essential to dedicate resources to understand ways to reach a representative group of the patient population, tailor the intervention so that patients are engaged to participate, and consider the broader family and community context that influences patients' capacity to manage their condition.

Opportunities for involving men and families in chronic disease management: a qualitative study from Chiapas, Mexico.

BACKGROUND: A healthy lifestyle intervention was implemented in primary care health centers in urban parts of Tuxtla Gutiérrez, Chiapas, Mexico with an aim of reducing cardiovascular disease risk for patients with type 2 diabetes and/or hypertension. During implementation, research questions emerged. Considerably fewer men participated in the intervention than women, and an opportunity was identified to increase the reach of activities aimed at improving disease self-management through strategies involving family members. A qualitative study was conducted to identify strategies to involve men and engage family members in disease management and risk reduction. METHODS: Nine men with hypertension and/or type 2 diabetes with limited to no participation in disease self-management and health promotion activities, six families in which at least one family member had a diagnosis of one or both conditions, and nine health care providers from four different government health centers were recruited for the study. Participants took part in semi-structured interviews. During interviews with families, genograms and eco-maps were used to diagram family composition and structure, and capture the nature of patients' relationships to the extended family and community resources. Transcripts were coded and a general inductive analytic approach was used to identify themes related to men's limited participation in health promotion activities, family support and barriers to disease management, and health care providers' recommendations. RESULTS: Participants reported barriers to men's participation in chronic disease management and healthy lifestyle education activities that can be grouped into two categories: internal and external factors. Internal factors are those for which they are able to make the decision on their own and external factors are those that are not related solely to their decision to take part or not. Four primary aspects were identified related to families' relationships with disease: different roles within the family, types of support provided to patients, the opportunity to prevent disease among family members without a diagnosis, and - in some cases - lack of family support or stress-induced by other family members. There was an overlap in recommended strategies for engaging men and family members in chronic disease management activities. CONCLUSIONS: There is an opportunity to increase the reach of interventions aimed at improving disease self-management by engaging men and family members. The proposed strategies presented by patients, family members, and providers have implications for health education and service provision at primary care health centers and for future research.

Chronic kidney disease among children in Guatemala / Enfermedad renal crónica en niños de Guatemala

OBJECTIVE: To describe the distribution of pediatric chronic kidney disease (CKD) in Guatemala, estimate incidence and prevalence of pediatric end-stage renal disease (ESRD), and estimate time to progress to ESRD. METHODS: This study analyzed the registry of the only pediatric nephrology center in Guatemala, from 2004-2013. Incidence and prevalence were calculated for annual periods. Moran's index for spatial autocorrelation was used to determine significance of geographic distribution of incidence. Time to progress to ESRD and associated risk factors were calculated with multivariate Cox regression. RESULTS: Of 1 545 patients from birth to less than 20 years of age, 432 had chronic renal failure (CRF). Prevalence and incidence of ESRD were 4.9 and 4.6 per million age-related population, respectively. Incidence was higher for the Pacific coast and Guatemala City. The cause of CRF was undetermined in 43% of patients. Average time to progress to ESRD was 21.9 months; factors associated with progression were: older age, diagnosis of glomerulopathies, and advanced-stage CKD at consultation. CONCLUSIONS: Prevalence and incidence of ESRD in Guatemala are lower than in other countries. This may reflect poor access to diagnosis. Areas with higher incidence and large proportion of CKD of undetermined cause are compatible with other studies from the geographic subregion. Findings on progression to ESRD may reflect delayed referral.

OBJETIVO: Describir la distribución de enfermedad renal crónica en niños en Guatemala, y calcular la incidencia y la prevalencia de nefropatía terminal en niños, así como el tiempo de progresión hasta la nefropatía terminal. MÉTODOS: Este estudio analizó el registro del único centro de nefrología pediátrica de Guatemala, del 2004 al 2013. La incidencia y la prevalencia se calcularon por períodos anuales. Se utilizó el índice de Moran como medida de la autocorrelación espacial con objeto de determinar la significación de la distribución geográfica de la incidencia. El tiempo de progresión a la nefropatía terminal, así como los factores de riesgo asociados, se calcularon mediante la regresión de Cox de variables múltiples. RESULTADOS: De 1 545 pacientes menores de 20 años, 432 padecían insuficiencia renal crónica. La prevalencia y la incidencia de nefropatía terminal fueron de 4,9 y 4,6 por millón de habitantes de esa misma edad, respectivamente. La incidencia fue mayor en la costa del Pacífico y en la Ciudad de Guatemala. En 43% de los pacientes la causa de la insuficiencia renal crónica era indeterminada. El tiempo promedio de progresión a una nefropatía terminal fue de 21,9 meses; los factores asociados con esa progresión fueron: la edad mayor, el diagnóstico de glomerulopatía y la enfermedad renal crónica en etapa avanzada en el momento de la consulta. CONCLUSIONES: La prevalencia y la incidencia de la nefropatía terminal en Guatemala son inferiores a las de otros países. Ello podría reflejar un acceso limitado al diagnóstico. La mayor incidencia y la amplia proporción de enfermedad renal crónica de causa indeterminada en algunas zonas son compatibles con las de otros estudios de la subregión geográfica. Los resultados en cuanto a progresión a una nefropatía terminal podrían ser el reflejo de la tardanza en la derivación.

Eyes wide open: an essay on developing an engaged awareness in global medicine and public health.

BACKGROUND: There is a growing understanding of the role social determinants such as poverty, gender discrimination, racial prejudice, and economic inequality play on health and illness. While these determinants and effects may be challenging to identify in parts of high-income countries, they are patently obvious in many other areas of the world. How we react to these determinants and effects depends on what historical, cultural, ideological, and psychological characteristics we bring to our encounters with inequity, as well as how our feelings and thoughts inform our values and actions. DISCUSSION: To address these issues, we share a series of questions we have asked ourselves-United States' citizens with experience living and working in Central America-in relation to our encounters with inequity. We offer a conceptual framework for contemplating responses in hopes of promoting among educators and practitioners in medicine and public health an engaged awareness of how our every day work either perpetuates or breaks down barriers of social difference. We review key moments in our own experiences as global health practitioners to provide context for these questions. Introspective reflection can help professionals in global medicine and public health recognize the dynamic roles that they play in the world. Such reflection can bring us closer to appreciating the forces that have worked both for and in opposition to global health, human rights, and well-being. It can help us recognize how place, time, environment, and context form the social determination of health. It is from this holistic perspective of social relations that we can work to effect fair, equitable, and protective environments as they relate to global medicine and public health.

Barriers and facilitating factors for disease self-management: a qualitative analysis of perceptions of patients receiving care for type 2 diabetes and/or hypertension in San José, Costa Rica and Tuxtla Gutiérrez, Mexico.

BACKGROUND: The burden of cardiovascular disease is growing in the Mesoamerican region. Patients' disease self-management is an important contributor to control of cardiovascular disease. Few studies have explored factors that facilitate and inhibit disease self-management in patients with type 2 diabetes and hypertension in urban settings in the region. This article presents patients' perceptions of barriers and facilitating factors to disease self-management, and offers considerations for health care professionals in how to support them. METHODS: In 2011, 12 focus groups were conducted with a total of 70 adults with type 2 diabetes and/or hypertension who attended urban public health centers in San José, Costa Rica and Tuxtla Gutiérrez, Chiapas, Mexico. Focus group discussions were transcribed and coded using a content analysis approach to identify themes. Themes were organized using the trans-theoretical model, and other themes that transcend the individual level were also considered. RESULTS: Patients were at different stages in their readiness-to-change, and barriers and facilitating factors are presented for each stage. Barriers to disease self-management included: not accepting the disease, lack of information about symptoms, vertical communication between providers and patients, difficulty negotiating work and health care commitments, perception of healthy food as expensive or not filling, difficulty adhering to treatment and weight loss plans, additional health complications, and health care becoming monotonous. Factors facilitating disease self-management included: a family member's positive experience, sense of urgency, accessible health care services and guidance from providers, inclusive communication, and family and community support.Financial difficulty, gender roles, differences by disease type, faith, and implications for families and their support were identified as cross-cutting themes that may add an additional layer of complexity to disease management at any stage. These factors also relate to the broader family and societal context in which patients live. CONCLUSIONS: People living with type 2 diabetes and hypertension present different barriers and facilitating factors for disease self-management, in part based on their readiness-to-change and also due to the broader context in which they live. Primary care providers can work with individuals to support self-management taking into consideration these different factors and the unique situation of each patient.

Evaluation of a demonstration primary health care project in rural Guatemala: the influence of predisposing, enabling and need factors on immunization coverage, equitable use of health care services and application of treatment guidelines.

In high- and low-resource settings, care is often provided inequitably, with more and higher-quality services being offered to those who need them less. We evaluated the influence of predisposing, enabling and need characteristics on immunization coverage and use of health services in a population-based primary health care model called the Inclusive Health Model in rural Guatemala. We also analyzed providers' application of treatment guidelines for children with pneumonia. A longitudinal cohort design was used from 2006 to 2009 to analyze data from the model's two demonstration sites. We found a significant positive association between families' health risk level and their use of health care services, with the model providing more services to those with greater need. Services are not provided differentially for those families with a higher or lower wealth level or selected sociodemographic characteristics. Distance from a clinic is significantly associated with lower service use, but this constraint decreases with time. Implementation of treatment guidelines does not vary with different provider characteristics. The Inclusive Health Care model's aim of offering care equitably to families living in its catchment area is reflected in these findings. This study offers an approach and conceptual model for tracking equity in service delivery that may be applicable in other settings.

Implementation and progress of an inclusive primary health care model in Guatemala: coverage, quality, and utilization.

OBJECTIVE: To describe a primary health care model designed specifically for Guatemala that has been implemented in two demonstration sites since 2004 and present results of a process evaluation of utilization, service coverage, and quality of care from 2005 to 2009. METHODS: Coverage, utilization, and quality were assessed by using an automated database linking census and clinical records and were reported over time. Key maternal and child health coverage measures were compared with national-level measures. RESULTS: The postnatal coverage achieved by the Modelo Incluyente de Salud of nearly 100.0% at both sites contrasts with the national average of 25.6%. Vaccination coverage for children aged 12-23 months in the Modelo Incluyente de Salud reached 95.6% at site 1 (Bocacosta, Sololá) and 92.7% at site 2 (San Juan Ostuncalco), compared with the national average of 71.2%. Adherence to national treatment guidelines increased significantly at both sites with a marked increase between 2006 and 2007. Utilization increased significantly at both sites, with only 7.5% of families at site 1 and 11.2% of families at site 2 not using services by the end of the 5-year period. CONCLUSIONS: Coverage, quality of care, and utilization measures increased significantly during the 5-year period when the service delivery model was implemented. This finding suggests a strong possibility that the model may have a benefit for health outcomes as well as for process measures. The Modelo Incluyente de Salud will be financially sustained by the Ministry of Health and extended to at least three additional sites. The model provides important lessons for primary care programs internationally.

Implementation and progress of an inclusive primary health care model in Guatemala: coverage, quality, and utilization / Ejecución y avance de un modelo inclusivo de atención primaria de salud en Guatemala: cobertura, calidad y utilización

OBJECTIVE: To describe a primary health care model designed specifically for Guatemala that has been implemented in two demonstration sites since 2004 and present results of a process evaluation of utilization, service coverage, and quality of care from 2005 to 2009. METHODS: Coverage, utilization, and quality were assessed by using an automated database linking census and clinical records and were reported over time. Key maternal and child health coverage measures were compared with national-level measures. RESULTS: The postnatal coverage achieved by the Modelo Incluyente de Salud of nearly 100.0 percent at both sites contrasts with the national average of 25.6 percent. Vaccination coverage for children aged 12-23 months in the Modelo Incluyente de Salud reached 95.6 percent at site 1 (Bocacosta, Sololá) and 92.7 percent at site 2 (San Juan Ostuncalco), compared with the national average of 71.2 percent. Adherence to national treatment guidelines increased significantly at both sites with a marked increase between 2006 and 2007. Utilization increased significantly at both sites, with only 7.5 percent of families at site 1 and 11.2 percent of families at site 2 not using services by the end of the 5-year period. CONCLUSIONS: Coverage, quality of care, and utilization measures increased significantly during the 5-year period when the service delivery model was implemented. This finding suggests a strong possibility that the model may have a benefit for health outcomes as well as for process measures. The Modelo Incluyente de Salud will be financially sustained by the Ministry of Health and extended to at least three additional sites. The model provides important lessons for primary care programs internationally.

OBJETIVO: Describir un modelo de atención primaria de salud diseñado específicamente para Guatemala que se ha ejecutado en dos sitios piloto desde 2004 y presentar los resultados de una evaluación de la utilización, la cobertura de servicios y la calidad de la atención entre 2005 y 2009. MÉTODOS: Se evaluaron la cobertura, la utilización y la calidad mediante una base de datos automatizada que relaciona los datos obtenidos a partir de un censo con los registros clínicos, y su evolución se informó a lo largo del tiempo. Se compararon las medidas clave de cobertura de la salud maternoinfantil con las medidas obtenidas en el nivel nacional. RESULTADOS: La cobertura posnatal lograda por el Modelo Incluyente de Salud, de casi 100,0 por ciento en ambos sitios, contrasta con el promedio nacional de 25,6 por ciento. La cobertura de vacunación de los niños de 12 a 23 meses de edad en dicho modelo alcanzó 95,6 por ciento en el sitio 1 (Bocacosta, Sololá) y 92,7 por ciento en el sitio 2 (San Juan Ostuncalco), en comparación con el promedio nacional de 71,2 por ciento. El cumplimiento de las directrices nacionales de tratamiento aumentó significativamente en los dos sitios, con un aumento acentuado entre 2006 y 2007. La utilización aumentó significativamente en ambos sitios; al finalizar el período de 5 años no usaban los servicios solo 7,5 por ciento de las familias en el sitio 1 y 11,2 por ciento de las familias en el sitio 2. CONCLUSIONES: Las medidas de cobertura, calidad de la atención y utilización aumentaron significativamente durante el período de 5 años durante el cual se ejecutó el modelo de prestación de servicios. Estos datos indican firmemente que el modelo puede mejorar tanto los resultados relacionados con la salud como las medidas de proceso. El Modelo Incluyente de Salud será mantenido económicamente por el Ministerio de Salud Pública y Asistencia Social y se extenderá, al menos, a tres sitios más. El modelo proporciona enseñanzas importantes para los programas de atención primaria de otros países.
