Improving accessibility to radiotherapy services in Cali, Colombia: cross-sectional equity analyses using open data and big data travel times from 2020.

In this study, we evaluated and forecasted the cumulative opportunities for residents to access radiotherapy services in Cali, Colombia, while accounting for traffic congestion, using a new people-centred methodology with an equity focus. Furthermore, we identified 1-2 optimal locations where new services would maximise accessibility. We utilised open data and publicly available big data. Cali is one of South America's cities most impacted by traffic congestion. METHODOLOGY: Using a people-centred approach, we tested a web-based digital platform developed through an iterative participatory design. The platform integrates open data, including the location of radiotherapy services, the disaggregated sociodemographic microdata for the population and places of residence, and big data for travel times from Google Distance Matrix API. We used genetic algorithms to identify optimal locations for new services. We predicted accessibility cumulative opportunities (ACO) for traffic ranging from peak congestion to free-flow conditions with hourly assessments for 6-12 July 2020 and 23-29 November 2020. The interactive digital platform is openly available. PRIMARY AND SECONDARY OUTCOMES: We present descriptive statistics and population distribution heatmaps based on 20-min accessibility cumulative opportunities (ACO) isochrones for car journeys. There is no set national or international standard for these travel time thresholds. Most key informants found the 20-min threshold reasonable. These isochrones connect the population-weighted centroid of the traffic analysis zone at the place of residence to the corresponding zone of the radiotherapy service with the shortest travel time under varying traffic conditions ranging from free-flow to peak-traffic congestion levels. Additionally, we conducted a time-series bivariate analysis to assess geographical accessibility based on economic stratum. We identify 1-2 optimal locations where new services would maximize the 20-min ACO during peak-traffic congestion. RESULTS: Traffic congestion significantly diminished accessibility to radiotherapy services, particularly affecting vulnerable populations. For instance, urban 20-min ACO by car dropped from 91% of Cali's urban population within a 20-min journey to the service during free-flow traffic to 31% during peak traffic for the week of 6-12 July 2020. Percentages represent the population within a 20-min journey by car from their residence to a radiotherapy service. Specific ethnic groups, individuals with lower educational attainment, and residents on the outskirts of Cali experienced disproportionate effects, with accessibility decreasing to 11% during peak traffic compared to 81% during free-flow traffic for low-income households. We predict that strategically adding sufficient services in 1-2 locations in eastern Cali would notably enhance accessibility and reduce inequities. The recommended locations for new services remained consistent in both of our measurements.These findings underscore the significance of prioritising equity and comprehensive care in healthcare accessibility. They also offer a practical approach to optimising service locations to mitigate disparities. Expanding this approach to encompass other transportation modes, services, and cities, or updating measurements, is feasible and affordable. The new approach and data are particularly relevant for planning authorities and urban development actors.

ESPAñOL: En este estudio, evaluamos y pronosticamos las oportunidades acumulativas para que los residentes accedan a los servicios de radioterapia en Cali, Colombia, teniendo en cuenta la congestión del tráfico, utilizando una nueva metodología centrada en las personas con un enfoque de equidad. Además, identificamos 1-2 ubicaciones óptimas donde los nuevos servicios maximizarían la accesibilidad. Utilizamos datos abiertos y macrodatos disponibles públicamente. Cali está entre las ciudades Sudamericanas más afectadas por la congestión del tráfico.Metodología: Usando un enfoque centrado en las personas, probamos una plataforma digital basada en la web desarrollada a través de un diseño participativo iterativo. La plataforma integra datos abiertos, incluyendo la ubicación de los servicios de radioterapia, los microdatos sociodemográficos desagregados de la población y los lugares de residencia, y los macrodatos de tiempos de viaje de la API de Google Distance Matrix. Usamos algoritmos genéticos para identificar ubicaciones óptimas para nuevos servicios. Pronosticamos oportunidades acumulativas de accesibilidad (ACO, por sus siglas en inglés) para el tráfico que va desde la congestión máxima hasta condiciones de flujo libre, con evaluaciones horarias hechas del 6 al 12 de julio de 2020 y del 23 al 29 de noviembre de 2020. La plataforma digital interactiva está públicamente disponible.Resultados Primarios y Secundarios: Presentamos estadísticas descriptivas y mapas de calor de la distribución de la población basados en isócronas de ACO de 20 minutos para viajes en coche. No existe un estándar nacional o internacional establecido para estos umbrales de tiempo de viaje. La mayoría de los informantes clave encontraron razonable el umbral de 20 minutos. Estas isócronas conectan el centroide poblacional ponderado de la zona de análisis de tráfico del lugar de residencia con la zona correspondiente del servicio de radioterapia con menor tiempo de viaje bajo condiciones variables de tráfico, que van desde el flujo libre hasta niveles de congestión de tráfico máximo. Además, realizamos un análisis bivariado de series temporales para evaluar la accesibilidad geográfica basada en el estrato económico. Identificamos 1-2 ubicaciones óptimas donde los nuevos servicios maximizarían el ACO de 20 minutos durante la congestión máxima del tráfico.Resultados: La congestión del tráfico redujo significativamente la accesibilidad a los servicios de radioterapia, afectando particularmente a las poblaciones vulnerables. Por ejemplo, el ACO urbano de 20 minutos en coche se redujo del 91% de la población urbana de Cali para viajes de hasta 20 minutos al servicio con flujo libre de tráfico, al 31% cuando hay congestión pico de tráfico durante la semana del 6 al 12 de julio de 2020. Los porcentajes representan la población con viajes de hasta 20 minutos en coche desde la residencia hasta el servicio de radioterapia. Grupos étnicos específicos, individuos con menor nivel educativo y residentes en las afueras de Cali experimentaron efectos desproporcionados, con la accesibilidad disminuyendo al 11% durante el tráfico máximo en comparación con el 81% durante el tráfico de flujo libre para hogares de bajos ingresos. Predecimos que agregar estratégicamente suficientes servicios en 1-2 ubicaciones en el este de Cali mejoraría notablemente la accesibilidad y reduciría las inequidades. Las ubicaciones recomendadas para los nuevos servicios se mantuvieron consistentes en nuestras dos mediciones.Estos hallazgos subrayan la importancia de priorizar la equidad y la atención integral en la accesibilidad a la atención médica. También ofrecen un enfoque práctico para optimizar las ubicaciones de los servicios para mitigar las disparidades. Es factible y accesible expandir este enfoque para abarcar otros modos de transporte, servicios y ciudades, o actualizar las mediciones. El nuevo enfoque y los datos son particularmente relevantes para las autoridades de planificación y los actores del desarrollo urbano.

PORTUGUêS: Neste estudo, avaliamos e previmos as oportunidades cumulativas para os residentes acessarem serviços de radioterapia em Cali, Colômbia, levando em consideração o congestionamento do tráfego, utilizando uma nova metodologia centrada nas pessoas com um foco na equidade. Além disso, identificamos 1-2 locais ideais onde os novos serviços poderiam maximizar a acessibilidade. Utilizamos dados abertos e big data disponíveis publicamente. Cali está entre as cidades sulamericanas mais afetadas pela congestionamento do tráfego.Metodologia: Usando uma abordagem centrada em pessoas, testamos uma plataforma digital baseada na web que foi desenvolvida através de um design participativo iterativo. A plataforma integra dados abertos, incluindo a localização dos serviços de radioterapia, microdados sociodemográficos desagregados por população e locais de residência, e big data da API Google Distance Matrix para os tempos de viagem. Utilizamos algoritmos genéticos para identificar locais ideais para novos serviços. Previmos oportunidades cumulativas de acessibilidade (ACO, por suas siglas em inglês) para o tráfego que varia desde o congestionamento máximo até condições de fluxo livre, com avaliações horárias de 6 a 12 de julho de 2020 e de 23 a 29 de novembro de 2020. A plataforma digital interativa está disponível publicamente.Resultados Primários e Secundários: Apresentamos estatísticas descritivas e mapas de calor da distribuição populacional baseados em isócronas de ACO de 20 minutos para viagens de carro. Não existe um padrão nacional ou internacional estabelecido para esses limites de tempo de viagem. A maioria dos entrevistados-chave considerou razoável o limite de 20 minutos. Essas isócronas conectam o centroide ponderado pela população da zona de análise de tráfego no local de residência e sua zona correspondente do serviço de radioterapia com o menor tempo de viagem sob condições variáveis de tráfego (que vão desde fluxo livre até níveis máximos de congestionamento do tráfego). Além disso, realizamos uma análise bivariada de séries temporais para avaliar a acessibilidade geográfica baseada na estratificação econômica. Identificamos 1-2 locais ideais onde os novos serviços maximizariam a ACO de 20 minutos durante o pico de congestionamento do tráfego.Resultados: O congestionamento do tráfego reduziu significativamente a acessibilidade aos serviços de radioterapia, afetando particularmente as populações vulneráveis. Por exemplo, a ACO urbana de 20 minutos de carro foi reduzida de 91% durante um fluxo livre de tráfego, para 31% durante picos de congestionamento de tráfego entre a semana de 6 a 12 de julho de 2020. As porcentagens representam a população com viagens de até 20 minutos de carro de sua residência até o serviço de radioterapia. Grupos étnicos específicos, indivíduos com menor nível educacional e residentes nos arredores de Cali experimentaram resultados desproporcionais, com a acessibilidade diminuindo para 11% durante o tráfego com congestionamento máximo em comparação com 81% durante o fluxo livre de tráfego para domicílios de baixa renda. Prevemos que adicionar estrategicamente serviços suficientes em 1-2 locais no leste de Cali melhoraria significativamente a acessibilidade e reduziria as desigualdades. Os locais recomendados para os novos serviços permaneceram consistentes em ambas medições. Esses resultados ressaltam a importância de priorizar a equidade e o atendimento integral na acessibilidade aos cuidados de saúde. Eles também oferecem uma abordagem prática para otimizar os locais dos serviços a fim de minimizar as desigualdades. A expansão dessa abordagem para abranger outros modos de transporte, serviços e cidades, ou a atualização das medições, é viável e acessível. A nova abordagem e os dados são particularmente relevantes para as autoridades de planejamento e os agentes do desenvolvimento urbano.

FRANçAIS: Dans cette étude, nous avons évalué et prévu les opportunités cumulées pour les résidents d'accéder aux services de radiothérapie à Cali, en Colombie, tout en tenant compte de la congestion du trafic en utilisant une nouvelle méthodologie centrée sur les personnes avec axée sur l'équité. De plus, nous avons identifié 1 à 2 emplacements optimaux où de nouveaux services maximiseraient l'accessibilité. Nous avons utilisé des données ouvertes et des macrodonnées tenues à disposition du public. Cali est l'une des villes d'Amérique du Sud les plus touchées par la congestion du trafic.Méthodologie: En utilisant une approche centrée sur les personnes, nous avons testé une plateforme numérique basée sur le web développée à travers une conception participative itérative. La plateforme intègre des données ouvertes, y compris la localisation des services de radiothérapie, les microdonnées sociodémographiques désagrégées de la population et les lieux de résidence, ainsi que les mégadonnées des temps de trajet de l'API Google Distance Matrix. Nous avons utilisé des algorithmes génétiques pour identifier les emplacements optimaux pour de nouveaux services. Nous avons prévu les opportunités cumulatives d'accessibilité (ACO, désignant l'acronyme en anglais) pour le trafic allant de la congestion maximale aux conditions de flux libre, avec des évaluations horaires du 6 au 12 juillet 2020 et du 23 au 29 novembre 2020. La plateforme numérique interactive est disponible publiquement.Résultats Primaires et Secondaires: Nous présentons des statistiques descriptives et des cartes thermiques de la distribution de la population basées sur des ACO de 20 minutes pour les trajets en voiture. Il n'existe pas de norme nationale ou internationale établie pour ces seuils de temps de trajet. La majorité des informateurs clés ont trouvé le seuil de 20 minutes raisonnable. Ces isochrones relient le centroïde pondéré par la population de la zone d'analyse du trafic au lieu de résidence à la zone correspondante du service de radiothérapie avec le temps de trajet le plus court sous des conditions de trafic variables allant du flux libre aux niveaux de congestion de trafic maximum. De plus, nous avons réalisé une analyse bivariée des séries chronologiques pour évaluer l'accessibilité géographique en fonction de la stratification économique. Nous avons identifié 1 à 2 emplacements optimaux où de nouveaux services maximiseraient l'ACO de 20 minutes pendant la congestion maximale du trafic.Résultats: La congestion du trafic a considérablement réduit l'accessibilité aux services de radiothérapie, affectant particulièrement les populations vulnérables. Par exemple, l'ACO urbain de 20 minutes en voiture est passé de 91 % de la population urbaine de Cali pour des trajets de jusqu'à 20 minutes vers le service avec un flux de trafic libre à 31 % lors des pics de congestion de trafic pendant la semaine du 6 au 12 juillet 2020. Les pourcentages représentent la population avec des trajets de jusqu'à 20 minutes en voiture depuis la résidence jusqu'au service de radiothérapie. Des groupes ethniques spécifiques, des individus ayant un niveau d'éducation inférieur et des résidents des périphéries de Cali ont subi des effets disproportionnés, avec une accessibilité diminuant à 11 % pendant le trafic maximal par rapport à 81 % pendant le flux de trafic libre pour les ménages à faible revenu. Ajouter suffisamment de services à 1-2 emplacements stratégiques dans l'est de Cali a le potential d'améliorer considérablement l'accessibilité et réduirait les inégalités. Les emplacements recommandés pour les nouveaux services sont restés cohérents dans nos deux mesures. Ces conclusions soulignent l'importance de prioriser l'équité et une prise en charge globale dans le cadre de l'accessibilité aux soins de santé. Elles offrent également une approche pratique pour optimiser les emplacements des services afin de réduire les disparités. Il est faisable et abordable d'étendre cette approche pour inclure d'autres modes de transport, services et villes, ou pour mettre à jour les mesures. La nouvelle approche et les données sont particulièrement pertinentes pour les autorités de planification et les acteurs du développement urbain.

Dynamic measurements of geographical accessibility considering traffic congestion using open data: a cross-sectional assessment for haemodialysis services in Cali, Colombia.

Background: Many cities with traffic congestion lack accessibility assessments accounting for traffic congestion and equity considerations but have disaggregated georeferenced municipal-level open data on health services, populations, and travel times big data. We convened a multistakeholder intersectoral collaborative group that developed a digital, web-based platform integrating open and big data to derive dynamic spatial-temporal accessibility measurements (DSTAM) for haemodialysis services. We worked with stakeholders and data scientists and considered people's places of residence, service locations, and travel time to the service with the shortest travel time. Additionally, we predicted the impacts of strategically introducing haemodialysis services where they optimise accessibility. Methods: Cross-sectional analyses of DSTAM, accounting for traffic congestion, were conducted using a web-based platform. This platform integrated traffic analysis zones, public census and health services datasets, and Google Distance Matrix API travel-time data. Predictive and prescriptive analytics identified optimal locations for new haemodialysis services and estimated improvements. Primary outcomes included the percentage of residents within a 20-min car drive of a haemodialysis service during peak and free-flow traffic congestion. Secondary outcomes focused on optimal locations to maximise accessibility with new services and potential improvements. Findings were disaggregated by sociodemographic characteristics, providing an equity perspective. The study in Cali, Colombia, used geographic and disaggregated sociodemographic data from the adjusted 2018 Colombian census. Predicted travel times were obtained for two weeks in 2020. Findings: There were substantial traffic variations. Congestion reduced accessibility, especially among marginalised groups. For 6-12 July, free-flow and peak-traffic accessibility rates were 95.2% and 45.0%, respectively. For 23-29 November, free-flow and peak traffic accessibility rates were 89.1% and 69.7%. The locations where new services would optimise accessibility had slight variation and would notably enhance accessibility and health equity. Interpretation: Establishing haemodialysis services in targeted areas has significant potential benefits. By increasing accessibility, it would enhance urban health and equity. Funding: No external or institutional funding was received.

La Atención Primaria en Salud, un camino inconcluso en Colombia: Lecciones aprendidas de la Primera Ola de la Pandemia por COVID-19 / Primary Health Care, an unfinished road in Colombia: Lessons learned from the First Wave of the COVID-19 Pandemic

RESUMEN Introducción: En 2020, Colombia adoptó diferentes medidas para mitigar el impacto de la pandemia por Covid-19, principalmente medidas de aislamiento social y fortalecimiento en la prestación de servicios hospitalarios. Sin embargo, el país no contempló acciones para abordar los otros problemas en salud, como tampoco consideró la relevancia de la Atención Primaria en Salud (APS) para responder a la pandemia. Por lo cual se realizó una investigación para indagar por la oferta y posicionamiento de la APS entre los tomadores de decisiones para atender la emergencia de Covid-19 durante la primera ola de la pandemia y los aprendizajes para las siguientes. Metodología: De abril a junio de 2020 se realizó un estudio descriptivo exploratorio mixto en 2 fases: (1) Encuesta a tomadores de decisiones, prestadores y académicos, y (2) Grupo focal a informantes clave. Resultados: La encuesta fue respondida por 227 participantes, 41 % académicos, 34.8 % prestadores y 17.6 % funcionarios de direcciones locales de salud; el 28.2 % consideró que la APS estuvo adaptada en los territorios para diferentes programas de salud por ciclo vital y entre el 80 al 98 % que la APS debía instaurarse en el territorio para vigilancia de casos, atención ambulatoria, manejo de pacientes crónicos, atención de otros programas y educación sanitaria. En el grupo focal participaron 12 informantes claves, quienes concluyeron que desde la autoridad sanitaria se debía promover la integración de la APS de forma urgente en los territorios, y garantizar una gobernanza eficaz para lograrlo; igualmente, recomendaron intensificar la alfabetización en salud y el empoderamiento de la población para la adopción de medidas individuales y colectivas. Conclusiones: Se concluye que la APS era una oportunidad para responder a la primera ola de la pandemia, como también para subsanar los problemas actuales y anticiparse a problemas futuros. Por lo cual, la APS debe convertirse en una política de Estado.

ABSTRACT Introduction: In 2020, Colombia adopted different measures to mitigate the impact of the Covid-19 pandemic, social isolation measures and strengthening the provision of hospital services. However, the country did not contemplate actions to address other health problems, nor did it consider the relevance of Primary Health Care (PHC) to respond to the pandemic. Therefore, an investigation was done to investigate the offer and positioning of PHC among decision-makers to address the Covid-19 emergency during the first wave of the pandemic and the learning for the following ones. Methodology: From April to June 2020, a mixed exploratory descriptive study was conducted in two phases: (1) a survey of decision-makers, providers, and academics, and (2) a focus group of key informants. Results: The survey was answered by 227 participants, 41 % academics, 34.8 % providers, and 17.6 % officials from local health directorates; 28.2 % considered that PHC was adapted in the territories for different life cycle health programs, and between 80 and 98 % that PHC should be established in the territory for case surveillance, outpatient care, management of chronic patients, care of other programs and health education. Twelve key informants participated in the focus group, who concluded that the health authority should urgently promote the integration of PHC in the territories, and guarantee effective governance to achieve it; Likewise, they recommended intensifying health literacy and the empowerment of the population for the adoption of individual and collective measures. Conclusions: It is concluded that PHC was an opportunity to respond to the first wave of the pandemic, as well as to correct current problems and anticipate future problems. Therefore, PHC must become a state policy.

Dynamic accessibility by car to tertiary care emergency services in Cali, Colombia, in 2020: cross-sectional equity analyses using travel time big data from a Google API.

OBJECTIVES: To test a new approach to characterise accessibility to tertiary care emergency health services in urban Cali and assess the links between accessibility and sociodemographic factors relevant to health equity. DESIGN: The impact of traffic congestion on accessibility to tertiary care emergency departments was studied with an equity perspective, using a web-based digital platform that integrated publicly available digital data, including sociodemographic characteristics of the population and places of residence with travel times. SETTING AND PARTICIPANTS: Cali, Colombia (population 2.258 million in 2020) using geographic and sociodemographic data. The study used predicted travel times downloaded for a week in July 2020 and a week in November 2020. PRIMARY AND SECONDARY OUTCOMES: The share of the population within a 15 min journey by car from the place of residence to the tertiary care emergency department with the shortest journey (ie, 15 min accessibility rate (15mAR)) at peak-traffic congestion hours. Sociodemographic characteristics were disaggregated for equity analyses. A time-series bivariate analysis explored accessibility rates versus housing stratification. RESULTS: Traffic congestion sharply reduces accessibility to tertiary emergency care (eg, 15mAR was 36.8% during peak-traffic hours vs 84.4% during free-flow hours for the week of 6-12 July 2020). Traffic congestion sharply reduces accessibility to tertiary emergency care. The greatest impact fell on specific ethnic groups, people with less educational attainment and those living in low-income households or on the periphery of Cali (15mAR: 8.1% peak traffic vs 51% free-flow traffic). These populations face longer average travel times to health services than the average population. CONCLUSIONS: These findings suggest that health services and land use planning should prioritise travel times over travel distance and integrate them into urban planning. Existing technology and data can reveal inequities by integrating sociodemographic data with accurate travel times to health services estimates, providing the basis for valuable indicators.

Materiales y métodos: se realizó una investigación bajo una metodología de estudio de caso de alcance interpretativo, y un análisis narrativo de construcción de la explicación a partir de siete entrevistas semiestructuradas, dos talleres de fotovoz y un mapeo de activos comunitarios para la salud desarrollado entre 26 habitantes de Medellín. Resultados: desde el modelo salutogénico se reconoció el empoderamiento de la comunidad, porque les ha permitido enfrentar las resistencias del contexto, creando prácticas positivas y saludables. Estas prácticas han movilizado sus activos comunitarios, permitiendo el desarrollo de un importante Sentido Comunitario de la Coherencia, con el cual la comunidad enfrenta los desafíos de la vida y construye experiencias coherentes. Conclusiones: los habitantes han buscado encontrar soluciones que respondan a la situación de pobreza, en un proceso de abajo hacia arriba que ha buscado crear espacios significativos, un mayor sentido de pertenencia y una percepción de seguridad de habitar este territorio. Finalmente, cuanto mejor se conoce el entorno, mejor se conocen las comunidades entre sí y se preserva mejor la salud comunitaria y el bienestar social.

Abstract Introduction: The urbanization model has caused an increase in social inequities, transgressing the ethical principles of social and spatial justice. The World Health Organization has identified urbanization as one of the major public health challenges of the 21st century. Objective: To understand the Sense of Community Coherence generated through community assets for health in the informal settlement El Faro in the northeast of the city of Medellin. Materials and methods: This research was conducted under a case study methodology with an interpretive scope, and a narrative analysis of construction of the explanation from seven semi-structured interviews, two photo-voice workshops and a mapping of community assets for health developed between 26 inhabitants of Medellin. Results: From the salutogenic model, the empowerment of the community was recognized because it has allowed them to face the resistance of the context creating positive and healthy practices. These practices have mobilized their community assets, allowing the development of an important Community Sense of Coherence with which the community faces the challenges of life and builds coherent experiences. Conclusions: The inhabitants have sought to find solutions that respond to the situation of poverty in a bottom-up process that has search to create significant spaces, a greater sense of belonging and a perception of security in inhabiting this territory. Finally, the better the environment is known, the better the communities know each other and the better the community health and social well-being are preserved.

Dynamic geographical accessibility assessments to improve health equity: protocol for a test case in Cali, Colombia.

This protocol proposes an approach to assessing the place of residence as a spatial determinant of health in cities where traffic congestion might impact health services accessibility. The study provides dynamic travel times presenting data in ways that help shape decisions and spur action by diverse stakeholders and sectors.  Equity assessments in geographical accessibility to health services typically rely on static metrics, such as distance or average travel times. This new approach uses dynamic spatial accessibility measures providing travel times from the place of residence to the health service with the shortest journey time. It will show the interplay between traffic congestion, accessibility, and health equity and should be used to inform urban and health services monitoring and planning. Available digitised data enable efficient and accurate accessibility measurements for urban areas using publicly available sources and provide disaggregated sociodemographic information and an equity perspective. Test cases are done for urgent and frequent care (i.e., repeated ambulatory care). Situational analyses will be done with cross-sectional urban assessments; estimated potential improvements will be made for one or two new services, and findings will inform recommendations and future studies. This study will use visualisations and descriptive statistics to allow non-specialized stakeholders to understand the effects of accessibility on populations and health equity. This includes "time-to-destination" metrics or the proportion of the people that can reach a service by car within a given travel time threshold from the place of residence. The study is part of the AMORE Collaborative Project, in which a diverse group of stakeholders seeks to address equity for accessibility to essential health services, including health service users and providers, authorities, and community members, including academia.

Grassroots innovation practices for social transformation of the health and well-being in a self-built settlement in Medellín-Colombia.

Grassroots innovation generates possibilities for the informal and collective production of the territory that the city itself denies, from bottom-up solutions for sustainable development and consumption, which respond to the local situation, interests, and values of the communities involved. This paper aims to identify how grassroots innovation practices take place and are shaped in 'El Faro', a self-built settlement at the urban border of the city of Medellín; and how these have allowed the social transformation of health and well-being. This was done from a qualitative approach with an interpretative scope, under the case study methodology. 'El Faro' is a space built by its inhabitants, in a process that they have called "dignity and resistance", becoming the promoter of what we identify as four 'grassroots innovation practices' developed around three main issues: community water management, artistic training and the creation of community public spaces. This process has allowed them, from the capacity of agency, to understand their poverty situation and face it, modifying the conditions that reproduce it and responding to unsatisfied basic needs, based on innovative solutions that guarantee conditions of life with dignity and well-being. Likewise, it generates mechanisms that reduce inequality because the community becomes the main driving agent for the construction of the city and the transformation of the health-disease process, through its community assets.

A Qualitative Study of the Health Perceptions in the Venezuelan Immigrant Population in Medellín (Colombia) and Its Conditioning Factors.

This study explored the general and oral health perceptions in the Venezuelan immigrant population in Medellín (Colombia) and its conditioning factors. A qualitative study involving Venezuelan immigrants ≥18 years with a minimum stay of six months in Colombia was conducted. Dentists, dental students, and other health professionals also participated. Semi-structured interviews (n = 17), focus groups (n = 2), and key informants' interviews (n = 4) were utilized. The interviews and focus groups were recorded and transcribed for later narrative content analysis. A high degree of vulnerability of participants was found due to the precarious living conditions from the premigratory moment and the lack of job placement possibilities at the time of settling in Colombia, where the migratory status played a fundamental role. Among the perceived needs, the mitigation of noncommunicable diseases stood out. Poor mental health symptoms (depression and anxiety) were perceived, and oral health was not a priority. Barriers to accessing health and dental care were found. The migrant condition was found to be a determinant that affected physical, mental, and oral health and the provision of health care. This situation is of interest to the construction of public health policies that guarantee access to fundamental rights.

Coronavirus disease 2019 and slums in the Global South: lessons from Medellín (Colombia).

The coronavirus disease 2019 (COVID-19) pandemic is hitting the world's most vulnerable people hardest, primarily the communities living in slums in the Global South. Lockdown, handwashing and social distancing are impossible privileges for many urban dwellers - measures which make structural inequities more visible, exacerbating racial, gender and class differences. There are many social determinants of health to explain these inequalities that trigger a high prevalence of infectious and chronic diseases. In Medellín (Colombia), it is a challenge to cope with this crisis, especially when the resources and aid provided by the government and institutions are limited. Yet, an organized social response is happening in some communes and slums, with high community participation, as a potentially effective key to control the pandemic. Once the emergency is over, communities in slums will have to face the social and economic reactivation, and effectively react to the multiple social and psychological consequences, new waves of COVID-19 or other pandemics.

[Community health assets mapping in a slum in Medellin (Colombia)]. / Mapeo de activos comunitario para la salud en un asentamiento informal de Medellín (Colombia).

OBJECTIVE: To describe how the community from El Faro neighborhood identifies its community assets, uses them to face life's challenges through the capacity of collective agency; and by generating community development processes, applying the salutogenic theory that considers people as active subjects, with the capacity to conserve and generate health and well-being, through the use of their own resources called health assets. METHODS: A map of community assets was made in 2018 in el Faro neighborhood, an informal settlement of Medellín, Colombia, following the phases recommended by other authors and from a qualitative, participatory approach that delves into the health situation of the community. RESULTS: In this process were identified 12 individual community assets, 12 collective, 13 institutional and 10 in the environment. The main community asset among the 47 described was community participation, from the agency capacity, mainly of its leaders who participating in their own organizations encourage development, identity construction and well-being. CONCLUSION: Asset mapping has served to identify intangible assets for the community and, in turn, this recognition has been useful in strengthening the agency's capacity for community development. This is a territory transformed by community reflection processes allowing to understand situations of exclusion and poverty, seeking to create a more livable place and developing a community capacity to solve their own problems, through solidarity and community support.

Urban Transformations and Health: Methods for TrUST-a Natural Experiment Evaluating the Impacts of a Mass Transit Cable Car in Bogotá, Colombia.

Background: Cable cars provide urban mobility benefits for vulnerable populations. However, no evaluation has assessed cable cars' impact from a health perspective. TransMiCable in Bogotá, Colombia, provides a unique opportunity to (1) assess the effects of its implementation on the environmental and social determinants of health (microenvironment pollution, transport accessibility, physical environment, employment, social capital, and leisure time), physical activity, and health outcomes (health-related quality of life, respiratory diseases, and homicides); and (2) use citizen science methods to identify, prioritize, and communicate the most salient negative and positive features impacting health and quality of life in TransMiCable's area, as well as facilitate a consensus and advocacy-building change process among community members, policymakers, and academic researchers. Methods: TrUST (In Spanish: Transformaciones Urbanas y Salud: el caso de TransMiCable en Bogotá) is a quasi-experimental study using a mixed-methods approach. The intervention group includes adults from Ciudad Bolívar, the area of influence of TransMiCable. The control group includes adults from San Cristóbal, an area of future expansion for TransMiCable. A conceptual framework was developed through group-model building. Outcomes related to environmental and social determinants of health as well as health outcomes are assessed using questionnaires (health outcomes, physical activity, and perceptions), secondary data (crime and respiratory outcomes) use of portable devices (air pollution exposure and accelerometry), mobility tracking apps (for transport trajectories), and direct observation (parks). The Stanford Healthy Neighborhood Discovery Tool is being used to capture residents' perceptions of their physical and social environments as part of the citizen science component of the investigation. Discussion: TrUST is innovative in its use of a mixed-methods, and interdisciplinary research approach, and in its systematic engagement of citizens and policymakers throughout the design and evaluation process. This study will help to understand better how to maximize health benefits and minimize unintended negative consequences of TransMiCable.

What the Puerto Rican hurricanes make visible: Chronicle of a public health disaster foretold.

García Márquez's novel, "Chronicle of a Death Foretold", narrates the multiple strands of a story leading up to a murder in a small Caribbean village. The novel shows both the incredulity of those who do not believe it possible that this tragic death could occur, and the impotence of those who see it coming but can do nothing to prevent it. Something akin to this double incapacity seems to be occurring today in Puerto Rico. In September 2017, the passage of Hurricanes Irma and María caused a public health disaster with large-scale death and destruction. Paradoxically, this catastrophe has made visible the need to evaluate the critical socio-environmental situation of this country, and to analyse the underlying social factors contributing to the problems caused by the hurricanes. Why did neither the US nor the Puerto Rican government react as expected when faced with such a serious situation? For decades, this country has been suppressed by colonial domination, exploitation of the workforce, and health discrimination. It has been a "laboratory", where colonial practices have institutionalized social control, racism, and inequality, with profound negative effects on society, quality of life and health equality. Poverty and unemployment have always been very high, and thousands of families live in precarious housing situations. Additionally, current labour reforms imposed as part of a neoliberal agenda, are eroding the job security and protections of the working population, while education, health, housing, pensions, energy, and land are being progressively privatized. What are the root causes of this situation? What future does the country await? To answer these questions, critical and comprehensive scrutiny of history showing what the hurricanes have helped to make visible is required. This shows that neoliberal colonialism has shaped the social features behind the principle health and inequality problems of the Puerto-Rican population.

Effectiveness of text messages, calls and e-mail on adherence to medical appointments. Review of systematic reviews and meta-analysis / Eficacia de los mensajes de texto, llamadas y e-mail en la adherencia a citas médicas. Revisión de revisiones sistemáticas y metaanálisis

Abstract Background: Mobile phones and all other forms of modern communication such as the Internet and instant messaging applications have become tools to improve attendance rates for medical appointments. Objectives: To evaluate the effectiveness of reminders to improve adherence to medical appointments. Methods: An overview of studies comparing the effectiveness and attendance rates for medical appointments between patients that did and did not receive reminders. Also, a meta-analysis was conducted to estimate the overall effect of keeping appointments depending on the age of the patients. Results: Seven reviews were identified which show that Short Message Service (SMS) improves adherence to medicai appointments. However, the meta-analysis showed a relative risk of 1,09 (CI 95%: 1,03 -1,11) for people with ages between 24 - 40 and 1,09 (CI 95% 1,05 - 1,14) for people with ages between 50 - 63, with regard to appointment assistance via SMS. Conclusions: The use of SMS reminders has a positive impact on medical appointment attendance. However, while reviewing the impact by age groups no differences were found.

Resumen Antecedentes: El teléfono móvil y cualquier forma de comunicación moderna como la Internet y las aplicaciones de mensajería instantánea se han convertido en herramientas para mejorar la tasa de asistencia a citas médicas. Objetivos: Evaluar la eficacia de los recordatorios para mejorar la adherencia a citas médicas. Métodos: Análisis de revisiones sistemáticas de estudios que comparan la efectividad y las tasas de asistencia a las citas entre los pacientes que reciben o no reciben recordatorios. Además, se realizó un metaanálisis para calcular el efecto global de la asistencia a citas en función de la edad de los pacientes. Resultados: Se identificaron siete revisiones que muestran que los mensajes de texto corto mejoraron la adherencia a las citas médicas. En el metaanálisis, agrupado por edad, se encontró un Odds Ratio de 1,09 (IC 95 %: 1,03 -1,11) en personas entre 24 - 40 años y de 1,09 (IC 95 %: 1,05 - 1,14) para las personas 50 a 63 años, respecto a la asistencia a citas mediante mensajes de texto corto. Conclusiones: El uso de los recordatorios vía mensajes de texto corto presenta un impacto positivo frente a la asistencia de las citas médicas. Sin embargo, al revisar el impacto por grupos de edad no encontramos diferencias.

ABSTRACT Objective To define the scope and the strategy of the Healthy City concept for Medellín. Material y Methods Mixed study with literature review, document analysis and involvement of actors. Results The construction of the concept leads to "a city to live more and better". Fifteen characteristics were identified and attributed to "Medellín, a Healthy City". The population assesses the current situation as average and gives more importance to the environment, safety, access to health services, housing and employment. In spite of this perception, and due to the programs and projects directed to increase health quality, the city has advanced towards the implementation of efforts to be acknowledged as a Healthy City. Discussion The construction of a Healthy City is specific for each context, and, in any case, it demands a combination of technical work and citizen participation, with the purpose of creating an own imaginary and identifying priorities. In the case of Medellín, assuming the strategy in a systematic manner is necessary to continue in the long term and to propose explicit goals and take actions to work along with different sectors of social development.(AU)

Ethnicity and Health in Colombia: What Do Self-Perceived Health Indicators Tell Us?

OBJECTIVE: To compare self-perceived health indicators between ethnic groups in Colombia. METHODS: Cross-sectional study with data from the 2007 National Public Health Survey (ENSP-2007). Data from 57,617 people ≥18 years were used. Variables included: belonging to an ethnic group (exposure); self-rated health; mental health problems, injuries for accidents/violence (outcomes); sex, age, education level and occupation (explicative/control). A descriptive study was carried out of the explicative variables, and the prevalence of the outcomes was calculated according to ethnicity, education level and occupation. The association between the exposure variable and the outcomes was estimated by means of adjusted odds ratios (OR) with 95% CI using logistic regression. Analyses were conducted separately for men and women. RESULTS: The prevalence of outcomes was higher in people reporting to belong to an ethnic group and differences were found by sex, ethnic groups and health outcomes. Women from the Palenquero group were more likely to report poor self-rated health (aOR 7.04; 95%CI 2.50-19.88) and injuries from accidents/violence (aOR 7.99; 95%CI 2.89-22.07). Indigenous men were more likely to report mental health problems (aOR 1.75; 95%CI 1.41-2.17). Gradients according to ethnicity, education, occupation and sex were found. CONCLUSIONS: Minority ethnic groups are vulnerable to reporting poor health outcomes. Political actions are required to diminish health inequalities in these groups.
