RESUMO

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.

RESUMO

[ABSTRACT]. Objectives. To (i) ascertain stakeholders’ perceptions of the contextual factors and resources necessary to successfully implement the AMORE platform, a tool that provides accessibility assessments for health care services, considering factors such travel time and traffic conditions, and (ii) identify potential barriers to and facilitators for enhancing spatial accessibility to health care services within the Colombian urban context. Methods. In this qualitative study, semi-structured interviews were conducted with a purposive sample of seven key stakeholders. The sample was drawn from individuals involved in development of policies in Colombia, service providers, and users, among others, who had expertise in the field. Interviews were conducted until saturation was reached. Results. The participants had positive views on the appearance of the AMORE platform, highlighting its user-friendly visualization. Suggestions were made about the variables used in the dashboard, the implementation of the platform, potential usage areas, and barriers and facilitators to implementation and use. Barriers included economic, political, and personnel challenges, while facilitators included creating a minimum viable product at a low cost and building interinstitutional and international cooperation. Conclusions. Innovations such as the AMORE platform have the potential to support decision-making processes across various sectors, including public policies and internal processes within private organizations, academia, and the community. However, implementing such a tool has financial, contextual and environmental challenges. The study identified key factors that were considered prerequisites for successfully implementing the AMORE platform in Colombian cities.

RESUMO

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.

RESUMO

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.

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
