    The uses of spatial analysis in medical geography: A review

    No full text
    This paper is a review of how geographers and others have used spatial analysis to study disease and health care delivery patterns. Point, line, area and surface patterns, as well as map comparisons and relative spaces are discussed. Problems encountered in applying spatial analytic techniques in medical geography are pointed out. The paper is intended to stimulate discussion about where medical geography can and should go in this area of study. Point pattern techniques include standard distance, standard deviational ellipses, gradient analysis and space and space-time clustering. Line methods include random walks, vectors and graph theory or network analysis. Under areas, location quotients, standardized mortality ratios. Poisson probabilities, space and space-time clustering, autocorrelation measures and hierarchical clustering are discussed. Surface techniques mentioned are isolines and trend surfaces. For map comparisons, Lorenz curves, coefficients of areal correspondence and correlation coefficients have been used. Case-control matching, acquaintance networks, multidimensional scaling and cluster analysis are examples of methods that are based on relative or non-metric spaces. The review gives rise to the discussion of several general points: problems encountered in spatial analysis, theory building and verification, the appropriate role of technique and computer use. Some suggestions are made for further use of spatial analytic techniques in medical geography: Monte Carlo simulation of point patterns, network analysis to study referral systems and health care for pastoralists, geographic information systems to assess environmental risk, difference mapping for disease and risk factor map comparisons and multidimensional scaling to measure social distance.spatial analysis technique methodology dimensionality relative space

    Physical access to primary health care in Andean Bolivia

    Limited physical access to primary health care is a major factor contributing to the poor health of populations in developing countries, particularly in mountain areas with rugged topography, harsh climates and extensive socioeconomic barriers. Assessing physical access to primary health care is an important exercise for health care planners and policy makers. The development of geographic information system (GIS) technology has greatly improved this assessment process in industrialized countries where digital cartographic data are widely available. In developing countries -- particularly in mountain areas, however, detailed cartographic data, even in hardcopy form, are nonexistent, inaccurate or severely lacking. This paper uses GIS technology to assess physical access to primary health care in a remote and impoverished region of Andean Bolivia. In addition, it proposes an alternative model of health personnel distribution to maximize physical accessibility. Methods involved extensive fieldwork in the region, utilizing GPS (global positioning system) technology in the development of the GIS and gathering other pertinent health data for the study. Satellite imagery also contributed to the development of the GIS and in the modeling process. The results indicate significant variation in physical access to primary health care across the three study sites. More importantly, this paper highlights the use of GIS technology as a powerful tool in improving physical accessibility in mountain areas of developing countries.Primary health care Bolivia GIS

    Approaches to sampling and case selection in qualitative research: examples in the geography of health

    No full text
    This paper focuses on the question of sampling (or selection of cases) in qualitative research. Although the literature includes some very useful discussions of qualitative sampling strategies, the question of sampling often seems to receive less attention in methodological discussion than questions of how data is collected or is analysed. Decisions about sampling are likely to be important in many qualitative studies (although it may not be an issue in some research). There are varying accounts of the principles applicable to sampling or case selection. Those who espouse 'theoretical sampling', based on a 'grounded theory' approach, are in some ways opposed to those who promote forms of 'purposive sampling' suitable for research informed by an existing body of social theory. Diversity also results from the many different methods for drawing purposive samples which are applicable to qualitative research. We explore the value of a framework suggested by Miles and Huberman [Miles, M., Huberman,, A., 1994. Qualitative Data Analysis, Sage, London.], to evaluate the sampling strategies employed in three examples of research by the authors. Our examples comprise three studies which respectively involve selection of: 'healing places'; rural places which incorporated national anti-malarial policies; young male interviewees, identified as either chronically ill or disabled. The examples are used to show how in these three studies the (sometimes conflicting) requirements of the different criteria were resolved, as well as the potential and constraints placed on the research by the selection decisions which were made. We also consider how far the criteria Miles and Huberman suggest seem helpful for planning 'sample' selection in qualitative research.Qualitative methods Sampling Geography of health

    Therapeutic landscapes in hospital design: a qualitative assessment by staff and service users of the design of a new mental health inpatient unit

    This pilot research project sought to provide a postoccupation assessment of a new mental health inpatient unit in East London, built under the Private Finance Initiative scheme. Qualitative discussion groups or unstructured interviews were used to explore the views of people who had been service users (but were currently well) and of nursing staff and consultants working in the new hospital. The participants gave their views on the aspects of the hospital which were beneficial or detrimental to well-being and the reasons for their views. Informants discussed hospital design in terms of: (1)�respect and empowerment for people with mental illness; (2)�security and surveillance versus freedom and openness; (3)�territoriality, privacy, refuge, and social interactions; (4)�homeliness and contact with nature; (5)�places for expression and reaffirmation of identity, autonomy, and consumer choice; and (6)�integration into sustainable communities. Themes emerging from this research were interpreted in light of ideas from geographical research on therapeutic landscapes constituted as physical, social, and symbolic spaces, as well as research from environmental psychology. The findings have practical implications for hospital design and underline the need to consider empowerment of patients in decisions over hospital design. We note the challenges involved in determining therapeutic hospital design given changing models of care in psychiatry, lack of consensus over models of care, and the varying and somewhat conflicting requirements these imply for the physical, social, and symbolic attributes of design of hospital spaces. We also note the implications of our findings for an interpretation of therapeutic landscapes as contested spaces.

    A incorporação da dimensão espacial na análise de políticas de saúde, com todas as suas conseqüências práticas, vem assumindo crescente importância, sustenta a autora com base num amplo levantamento de fontes na literatura especializada. Há um avanço real na passagem da atenção ao território para a atenção ao espaço, com suas tensões internas. A ênfase na heterogeneidade do espaço urbano permite dirigir-se de maneira mais informada e rigorosa para as questões centrais da justiça e da cidadania.<br>The incorporation of the spatial dimension in the analysis of health policies, with all its practical consequences, shows a growing importance, holds the author on the basis of a wide survey of sources in the specialized literature. There is a real advance in the passage from the attention to territory to the attention to space, with its internal tensions. The emphasis on the heterogeneity of urban space allows addressing in a more informed and rigorous way the central questions of justice and citizenship
