Dynamic Geographical Accessibility Assessments to Improve Health Equity: Protocol for a Test Case in Cali, Colombia (Evaluaciones Dinámicas De Accesibilidad Geográfica Para Mejorar La Equidad: Prueba En Cali, Colombia: Protocolo De Investigación)

Cross-Sectional Equity Analysis of Accessibility by Automobile to Haemodialysis Services in Cali, Colombia, in 2020

“…The rationale and methods for this study are published. [1][2][3][4] This study assesses accessibility by car to the service with the shortest travel time among the 11 haemodialysis services, which together had 370 haemodialysis chairs in 2020. According to an international traffic scorecard, Cali was the fifth-most congested city in South America and 76th globally.…”

“…This information helps us understand how long people need to travel to access healthcare and can be used to identify areas where access to healthcare may be limited. 1,2 This study is part of the AMORE Project, a proof of concept evaluating new approaches to place-based dynamic spatial-temporal accessibility measures (DSTAM) to health services by integrating publicly available data. Using existing data facilitates fast, affordable assessments of DSTAM, and the AMORE Project seeks to deliver granular information for an entire city with an equity perspective.…”

“…Using existing data facilitates fast, affordable assessments of DSTAM, and the AMORE Project seeks to deliver granular information for an entire city with an equity perspective. [1][2][3] An earlier report assessed accessibility in urban Cali to tertiary care emergency services, which are essential to all residents. 4 This study assesses accessibility to haemodialysis services.…”

“…This study thus provides a proxy measurement and new data to inform health services planning and a strategy for reducing inequities in accessibility. 1 Haemodialysis is an expensive, life-saving treatment usually administered three times weekly for about four hours. Regular use and adherence usually improve the quality of life of people with end-stage renal disease (ESRD).…”

“…A 20-minute travel-time threshold was set to predict the effects of adding new services in one or two new locations that would optimise accessibility. 1 An interface of the web-based AMORE Platform is available for readers to test assumptions, modify parameters, and draw conclusions. 22,27,28 This study advances the global research priorities for urban health.…”
