“…GIS technology has been used to estimate access to cancer care across the United States 8 and estimate local demand by major cancer care facilities in the United States. 9 Our study is the first to our knowledge to use GIS technology to estimate the unmet need for HCT.…”

“…Efforts are under way to collect patient ZIP code data so that the frequency of patients receiving care within designated market areas can be more accurately assessed. Other approaches, such as the twostep floating catchment area method, 9 where both patient travel time and facility capacity are used to estimate access and local demand for cancer facilities, should be considered. Lastly, the NMDP is in the process of reviewing market analysis data with individual transplant centers to assess accuracy and utility.…”

“…6 It has also been used to perform spatial analysis aimed at examining access, demand, and use of cancer care. [7][8][9][10] A common geographic approach to measuring health care access is with a distance-based measure. Travel-time estimates from patients' places of residence to treatment centers provide the most accurate information regarding distance-based access.…”

Purpose: Allogeneic hematopoietic cell transplantation (HCT) is an increasingly used therapy for many patients with hematologic malignancies and other marrow failure or immune system disorders. The purpose of this study was to quantify and visualize both the demand and unmet need for HCT. Methods:HCT use for 2012 was described using the Center for International Blood and Marrow Transplant Research registry. Potential demand for HCT was calculated using 2012 SEER data and published literature for HCT-treatable conditions. Point locations of transplant centers were geocoded using geographic information system (GIS) software; Thiessen polygons were created to establish adult (age 20 to 74 years) and pediatric (age 0 to 19 years) market areas. Market-area population estimates were calculated using 2012 population estimates by age aggregated by census block. Results: US market areas for HCTs were identified separatelyfor transplant centers treating adult (n ϭ 62) and pediatric patients (n ϭ 52). Overall HCT demand among adults was 16,096, with an unmet need for HCTs of 10,276 patients. For pediatric patients, the total demand was 4,561, with an unmet need of 3,213 potential recipients. Evaluation of adult and pediatric market areas indicated that the largest unmet needs tended to be in areas with large populations. Conclusion:Market-area maps and statistics developed using GIS will help communicate the unmet need for HCT, inform policy, and assist transplant centers in planning for the anticipated growth in HCT use.

“…With regard to tillage accessibility, the proportions of rural residents that could accept the farmland access within 10, 20 and 30 min are 100%, 59% and 20.60%, respectively, which are used as the three key points of the distance decay function. Based on previous research (Shi et al, 2012;Wan et al, 2012b), the improved Gaussian function is used to construct a piecewise distance decay function, which is given by:…”

“…Several studies have attempted to address these shortcomings (Wang, 2012). Some scholars introduced continuous distance decay functions, such as the kernel density, Gaussian, inverse power and exponential functions (Dai, 2010;Schuurman et al, 2010;Dai and Wang, 2011;Langford et al, 2012), whereas others employed discrete distance decay functions, including the multiple discrete and three-zone hybrid to improve the method (Luo and Qi, 2009;Shi et al, 2012;Wan et al, 2012a). However, empirical evidence that can guide the choice of one decay function over another has remained minimal (McGrail, 2012).…”

Rural settlements are the main carriers of agriculture, rural areas and farmers; thus, optimizing the production and living space of rural settlements is highly significant to rural development. Taking the effective allocation of resources as the starting point, a suitability evaluation system of rural settlements, based on accessibility of production and living, was proposed in this study to provide scientific basis for the optimization of production and living space. The accessibility of production and living was measured by an improved two-step floating catchment area method, which considered proximity and availability based on the inclination of rural residents. The suitability evaluation system consisted of traditional suitability evaluation and newly proposed limiting factor identification based on the loss score proportion of suitability. Tingzu Town of Hubei Province, China, was chosen as the case study area. Based on the results of the suitability evaluation system, corresponding suggestions on rural land consolidation, industry division, as well as the layout of health care and education facilities were proposed to optimize the production and living space of rural settlements in Tingzu Town. It is found that the suitability evaluation based on accessibility of production and living is more scientific and accurate than the traditional ones which significantly overestimate production and living convenience. Moreover, the limiting factor identification can help us put forward suggestions according to local conditions and bring about the highly targeted optimization of production and living space of rural settlements.

How do administrative borders affect accessibility to hospitals? The case of Sweden

An administrative border might hinder the optimal allocation of a given set of resources by restricting the flow of goods, services, and people. In this paper, we address the question: Do administrative borders lead to poor accessibility to public service? In answering the question, we have examined the case of Sweden and its regional administrative borders and hospital accessibility. We have used detailed data on the Swedish road network, its hospitals, and its geo-coded population. We have assessed the population's spatial accessibility to Swedish hospitals by computing the inhabitants' distance to the nearest hospital. We have also elaborated several scenarios ranging from strongly confining regional borders to no confinements of borders and recomputed the accessibility. Our findings imply that administrative borders are only marginally worsening the accessibility.
