This article synthesizes two GIS-based accessibility measures into one framework, and applies the methods to examining spatial accessibility to primary health care in the Chicago ten-county region. The floating catchment area (FCA) method defines the service area of physicians by a threshold travel time while accounting for the availability of physicians by their surrounded demands. The gravity-based method considers a nearby physician more accessible than a remote one and discounts a physician…

Comparing GIS-Based Methods of Measuring Spatial Accessibility to Health Services

A microscopic study compared two GIS-based measures of accessibility in a case study of dialysis service centers in Chicago and found a significant mismatch of the accessibility ratios between the two methods.

Measuring Spatial Health Disparity Using a Network-Based Accessibility Index Method in a GIS Environment: A Case Study of Hillsborough County, Florida

A NHAIM is developed to examine the spatial disparity in health care access in Hillsborough County, Florida, determining the locations of registered medical doctors and facilities using data from Medical Quality Assurance Services (MQA) and the U.S. Census.

Spatio-temporal modelling and analysis of spatial accessibility to primary health care: A case study of Bhutan

One of the most important aspects of primary health care is related to the ease of access to health care providers. It is a challenging task in most countries to adequately and equitably provide

Assessment of the spatial accessibility to health professionals at French census block level

The Index of Spatial Accessibility (ISA) is a multidimensional and improved measure, which combines the volume of services relative to population size with the proximity of servicesrelative to the population’s location, available at the smallest feasible geographical scale.

The approaches to measuring the potential spatial access to urban health services revisited: distance types and aggregation-error issues

Comparing discrepancies in results for the geographical accessibility of health services computed using six distance types (Euclidean and Manhattan distances; shortest network time on foot, by bicycle, by public transit, and by car), four aggregation methods, and fourteen accessibility measures shows that the evaluation of potential geographic access may vary a great deal depending on the accessibility measure and, to a lesser degree, the type of distance and aggregation method.

The first comparison between continuous and zonal (step) decay functions and specifically their effect within both rural and metropolitan populations is presented, demonstrating the necessary combination of both a distance-decay function and variable catchment size function in order to appropriately measure healthcare access across all geographical regions.

The spatial accessibility of a number of immigrant groups to linguistically diverse primary care (family) physicians in the Toronto Census Metropolitan Area is analyzed and the use of the geographical information system (GIS) in public health research is demonstrated and yields important policy implications for public health planning.

Spatial Accessibility to Health Care Services: Identifying under-Serviced Neighbourhoods in Canadian Urban Areas

The results show that the low access neighbourhoods tend to be clustered in the neighbourhoods at the urban periphery and immediately surrounding the downtown area, which enhances the understanding of spatial accessibility to health care services at the neighbourhood level.

Distance from the Primary Health Center: A GIS method to study geographical access to health care

A method for calculation of distances between the PHC and the population it serves using the data available from the local health authorities and the Swedish Central Statistical Bureau is described.

The geographical accessibility of hospitals to the aged: a geographic information systems analysis within Illinois.

The vast majority of Illinois' aged population is within close proximity to hospital facilities, and there is no evidence that the aged's geographical accessibility to hospitals is less favorable than that of the general population.

Some Methods for Measuring the Geographic Accessibility of Medical Services in Rural Regions

Two complementary measures of geographic access to medical care in rural regions that necessitate only modest information inputs on the location of services and client populations are presented.

The use of health service areas for measuring provider availability.

This work has defined health care service areas for the coterminous United States, based on 1988 Medicare data on travel patterns between counties for routine hospital care, using hierarchical cluster analysis to group counties into 802 service areas.

How Accessibility Shapes Land Use

Abstract An empirical examination of the residential development patterns illustrates that accessibility and the availability of vacant developable land can be used as the basis of a residential land
