There is a longstanding policy interest in understanding the impacts of changes in access to public and private services in rural areas. To date much of the empirical analysis concerning changing patterns of accessibility has been predicated on assumptions regarding the mode of transport used to access such facilities. The availability of new and open sources of data, and the increasing sophistication of spatial analytical tools, has enabled alternative transportation modes to be included when investigating the impact of service changes.

To date, much of this analysis has been conducted at spatially aggregated scales such as that of local authorities or postcode sector. Hidden within such aggregate-level analysis however are geographical differences in the local provision of care services.

Research that leads to a fuller understanding of the types of factors influencing spatial and temporal patterns of these so-called "Did-Not-Attends" (DNAs) is therefore timely. This research articulates the results of a study that uses machine learning approaches to investigate whether these factors are consistent across a range of medical specialities.

Using the case study of potential access to primary healthcare services in Wales, Geographic Information System (GIS)-based tools that permit a consideration of population-to-provider ratios over space are used to examine variations in geographical accessibility to general practitioner (GP) surgeries offering appointment times outside of 'core' operating hours. Correlation analysis is used to explore the association of accessibility scores with potential demand for such services using UK Population Census data.

By drawing on the findings from the existing literature, this study examines associations between small-area variations in rates of new registrants to the UK organ donor register (ODR) within Wales and key demographic factors. Using map-based visualisations and statistical regression methods, spatial patterns in new registrants to the ODR are identified within Wales, a country which moved to an opt-out system of consent for organ donation following the Human Transplantation (Wales) Act 2013.

This paper proposes methodological enhancements to increase the sophistication of the 2SFCA methodology by incorporating both public and private transport modes using dedicated network datasets. The proposed model yields separate accessibility scores for each modal group at each demand point to better reflect the differential accessibility levels experienced by each cohort.

The unique properties of geographic tools for remote sensing of the atmosphere offer a distinct ability to characterize and model aerosols in the urban atmosphere for evaluation of impacts on health. Asthma, as a manifestation of upper respiratory disease prevalence, is a good example of the potential interface of geographic and public health interests.

Treatment of acute stroke with thrombolytic therapy has been limited because of the narrow treatment window. Distance from home to hospital may affect arrival time and likelihood of receiving thrombolytic therapy for acute stroke. The present study included stroke subjects seen at Barnes Jewish Hospital in 2006-2007, residing in St Louis City/County, who were at home at the time of the stroke (n = 416).

It also aimed to establish the demographic characteristics of these smokers in terms of age, gender and deprivation status, and to raise the awareness of practice staff about smoking cessation.
Methods: Data were collected from consecutive patients (aged over 16 years) attending two general dental practices over a period of one month.
Aims: The aim of this audit was to quantify the number of patients that received a dental general anaesthetic (DGA) between 1999 and 2007 following referral from a general dental practice. It also aimed to establish the deprivation status of those referred and to investigate further dental treatment pathways of these patients.
Methods: Data were collected from all patient records held by the practice.
This study uses a geographical information system (GIS) and statistical analysis to look for patterns in referrals to a British cancer genetics service. In this case, familial cancers are taken to be those that can develop when an individual inherits DNA mutations that cause an increased risk of cancer. Between 1998 and 2006 the Cancer Genetics Service for Wales received nearly 11,000 referrals for patients resident in Wales and it is the service database recording those referrals which is the subject of this secondary analysis.

We compared "point-in-polygon" (ArcGIS, commercial firm, and aerial photography) and the "look-up table" method (SAS/GIS) to allocate addresses to census geography, particularly as it relates to census-based poverty rates.
Methods: We randomly selected 299 addresses of children treated for asthma at an urban emergency department (1999-2001).
Despite recent U.K. Government commitments' to encourage public participation in environmental decision making, those exercises conducted to date have been largely confined to 'traditional' modes of participation such as the dissemination of information and in encouraging feedback on proposals through, for example, questionnaires or surveys.

Concern that living near a particular landfill site in Wales caused increased risk of births with congenital malformations led us to examine whether residents living close to 24 landfill sites in Wales experienced increased rates of congenital anomalies after the landfills opened compared with before they opened. We carried out a small-area study in which expected rates of congenital anomalies in births to mothers living within 2 km of the sites, before and after opening of the sites, were estimated from a logistic regression model fitted to all births in residents living at least 4 km away from these sites and hence not likely to be subject to contamination from a landfill, adjusting for hospital catchment area, year of birth, sex, maternal age, and socioeconomic deprivation score. We investigated all births from 1983 through 1997 with at least one recorded congenital anomaly [International Classification of Diseases, Ninth Revision (ICD-9), codes 7400-7599; International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10), codes Q000-Q999].

Methods: Postcodes of patients during a 4-year period were used to examine spatial patterns using a Geographical Information System (GIS). Referral rates were compared visually and statistically to explore yearly variation for administrative areas in Wales.
The use of geographical information systems (GIS) in a variety of application areas points to an increasing interest in the spatial aspects of health policies. Despite the fact that most public sector organisations in the United Kingdom (UK) have access to such software tools, there has not been a comprehensive review of take-up within the health sector. In this paper, we report on a recently completed mixed-method research project that has examined the current levels of GIS use in the UK National Health Service, and focus our discussion on health authorities (HAs).

This paper discusses spatial trends in referral patterns to a cancer genetics service. It presents a literature review outlining the paucity of existing research, a preliminary analysis at the Unitary Authority level in Wales and advances a programme of further research to be conducted at a more detailed spatial level. The preliminary analysis shows a weak negative relationship between referral rates from primary care and social deprivation by Unitary Authority (Spearman rank correlation coefficient, sigma = -0.

Prescribing of specific groups of drugs are examined, namely antidepressants; bronchodilators and inhaled corticosteroids for treating asthma; and oral antidiabetics and insulin for diabetes. It is hypothesised that the volumes and costs of prescriptions are determined by the characteristics of both doctors/practices (number and age of doctors; training and fundholding status of practices; single-handed practices and doctors per patient) and their patients (age; gender; ethnicity; deprivation).

A major benefit of using GIS to examine sociodemographic profiles of patients on a dental register is to inform policy makers.
Method: We illustrate the advantages of such an approach by using a postcoded list of registered patients for a dental practice in Swansea.
