BACKGROUND Geographic information systems (GIS) mapping is fairly novel in describing utilization of health services. Our study is the first to use GIS to demonstrate that telehealth pediatric specialty service access would create substantial savings in travel time and distance compared with accessing a tertiary-care center for similar service. MATERIALS AND METHODS A retrospective chart revi...

Modelling access to services, using cost path analysis and distance decay models, can be improved if travel time rather than just distance is taken into account. If just straight line distance is used then traffic congestion in urban areas and rough bendy rural roads are not considered in the analysis and the results are subsequently distorted. An accurate road network layer that shows travel s...

PURPOSE The objective of this study was to compare multiple methods for estimation of PWV from 4D flow MRI velocity data and to investigate if 4D flow MRI-based PWV estimation with piecewise linear regression modeling of travel-distance vs. travel time is sufficient to discern age-related regional differences in PWV. METHODS 4D flow MRI velocity data were acquired in 8 young and 8 older (age:...

BACKGROUND Information on travel distance and time to care for children with birth defects is lacking. We examined factors associated with travel distance and time to cleft care among children with orofacial clefts. METHODS In 2006, a mail/phone survey was administered in English and Spanish to all resident mothers of children with orofacial clefts born 2001 to 2004 and identified by the Nort...

Long-distance travel across multiple time zones presents unique challenges for patients taking insulin, requiring adjustments in both timing and dosage of basal insulin when several times zones (≥5) are traversed. Travel across the International Date Line adds to the confusion, as existing resources and dosing calculators often do not account for the date change. We review recommendations from ...

The community-contributed command georoute is designed to calculate travel distance and time between two addresses or geographical points identified by their coordinates. Since its conception description Weber Péclat (2017, Stata Journal 17: 962–971), the has been gradually maintained enriched. new version of presented in this article encompasses major improvements, such as possibility specify ...
