A spatial sensitivity analysis of a spatially explicit model for myxomatosis in Belgium Universiteit Gent
Development and validation of an automated and marker-free CT-based spatial analysis method (CTSA) for assessment of femoral hip implant migration In vitro accuracy and precision comparable to that of radiostereometric analysis (RSA) Vrije Universiteit Brussel
Background and purpose - We developed a marker-free automated CT-based spatial analysis (CTSA) method to detect stem-bone migration in consecutive CT datasets and assessed the accuracy and precision in vitro. Our aim was to demonstrate that in vitro accuracy and precision of CTSA is comparable to that of radiostereometric analysis (RSA). Material and methods - Stem and bone were segmented in 2 CT datasets and both were registered pairwise. ...
Geographic accessibility to public and private health facilities in Kenya in 2021: an updated geocoded inventory and spatial analysis Instituut voor Tropische Geneeskunde
OBJECTIVES: To achieve universal health coverage, adequate geographic access to quality healthcare services is vital and should be characterized periodically to support planning. However, in Kenya, previous assessments of geographic accessibility have relied on public health facility lists only, assembled several years ago. Here, for the first time we assemble a geocoded list of public and private health facilities in 2021 and make use of ...
A vulnerability index for COVID-19: spatial analysis at the subnational level in Kenya Instituut voor Tropische Geneeskunde
BACKGROUND: Response to the coronavirus disease 2019 (COVID-19) pandemic calls for precision public health reflecting our improved understanding of who is the most vulnerable and their geographical location. We created three vulnerability indices to identify areas and people who require greater support while elucidating health inequities to inform emergency response in Kenya.
METHODS: Geospatial indicators were assembled to create ...
Access to emergency hospital care provided by the public sector in sub-Saharan Africa in 2015: a geocoded inventory and spatial analysis Instituut voor Tropische Geneeskunde
BACKGROUND: Timely access to emergency care can substantially reduce mortality. International benchmarks for access to emergency hospital care have been established to guide ambitions for universal health care by 2030. However, no Pan-African database of where hospitals are located exists; therefore, we aimed to complete a geocoded inventory of hospital services in Africa in relation to how populations might access these services in 2015, ...
Determinants of subnational disparities in antenatal care utilisation: a spatial analysis of demographic and health survey data in Kenya Instituut voor Tropische Geneeskunde
BACKGROUND: The spatial variation in antenatal care (ANC) utilisation is likely associated with disparities observed in maternal and neonatal deaths. Most maternal deaths are preventable through services offered during ANC; however, estimates of ANC coverage at lower decision-making units (sub-county) is mostly lacking. In this study, we aimed to estimate the coverage of at least four ANC (ANC4) visits at the sub-county level using the 2014 ...
