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

Geographical accessibility and inequalities in access to childbirth care in the Grand Conakry metropolitan area, Guinea: a spatial modelling study

Research Square (Research Square), Год журнала: 2024, Номер unknown

Опубликована: Сен. 16, 2024

We modelled geographic accessibility, coverage, and wealth-based inequalities for childbirth care in Grand Conakry, Guinea. assembled boundaries, health facilities, wealth index, road network, elevation, landcover, geo-traced travel speeds. Using least-cost path algorithm, we computed times to the nearest facility by level sector. quantified coverage (% of women childbearing age) within 15, 30, 60-minutes its variation index. Average speeds ranged from 14 28 km/h. Travel any took 8-minutes, increasing 22 public hospitals (range 5 33-minutes across communes). Coverage was 100% 30-minutes facility, dropping 82% hospitals, varying communes. Slower due traffic substantially increased time reduced coverage. Pro-rich emerged, especially peri-urban communes with longer times. Targeted interventions are needed reach equitable access care.
