Preface This book is an expression of the myriad ways in which the range of geospatial methods and technologies can be applied to the analysis of issues related to human and environmental health. Since the study and management of the many diverse issues related to human health is one of the most important aspects of human endeavor it is not surprising that it has been a fruitful area for application of geo- spatial analysis tools. Contributions to this book run the gamut of these diverse applications areas from more classical medical geography to the study of infectious disease to environmental health. The tools used in these studies are also diverse– ranging from GIS as a core and unifying technology to geo-spatial statistics and the computer processing of remotely-sensed imagery. This book should prove useful for practitioners and researchers in the health care and allied fields as well as geographers, epidemiologists, demographers, and other academic researchers. Today one sees a continual increase in the power and ease of use of GIS, better integration and easier availability of related technologies, such as remote sensing and global positioning systems and rapidly falling costs of platforms, peripherals, and programs. Thus, one now sees an increasingly large cadre of users of geo-spatial technology in all fields, including health related ones. The methods and examples provided in this work are a starting point for this growing group of users who will find the power of spatial analysis tools and the increasing availability of data sources to enable them to obtain answers and to arrive at solutions to a host of critical health care related issues. The tools and knowledge are readily available and the skills can be developed by any dedicated user; therefore, what direction users of GIS in health related fields choose to take this and related technologies is now primarily limited by their imaginations.

Until fairly recently, as was the case with most other geographic fields of study, medical geographers collected and analyzed their data using methods such as making on-the- ground observations (e.g., of malarial mosquito habitats) and drawing maps (e.g., of hospital catchment areas) by hand. With the advent of geographic information systems (GIS) and remote sensing (RS) technologies, computers which could handle large amounts of data, and sophisticated spatial analytic software programs, medical geography has been transformed. It is now possible, for example, to make many measurements from far above the earth’s surface and produce dozens of maps of disease and health phenomena in a relatively short time.

  • Statistics Making an Impact
    John Pullinger J. R. Statist. Soc. A (2013) 176, Part 4, pp. 819–839 Statistics making an impact John Pullinger House of Commons Library, London, UK [The address of the President, delivered to The Royal Statistical Society on Wednesday, June 26th, 2013] Summary. Statistics provides a special kind of understanding that enables well-informed deci- sions. As citizens and consumers we are faced with an array of choices. Statistics can help us to choose well. Our statistical brains need to be nurtured: we can all learn and practise some simple rules of statistical thinking. To understand how statistics can play a bigger part in our lives today we can draw inspiration from the founders of the Royal Statistical Society. Although in today’s world the information landscape is confused, there is an opportunity for statistics that is there to be seized.This calls for us to celebrate the discipline of statistics, to show confidence in our profession, to use statistics in the public interest and to champion statistical education. The Royal Statistical Society has a vital role to play. Keywords: Chartered Statistician; Citizenship; Economic growth; Evidence; ‘getstats’; Justice; Open data; Public good; The state; Wise choices 1. Introduction Dictionaries trace the source of the word statistics from the Latin ‘status’, the state, to the Italian ‘statista’, one skilled in statecraft, and on to the German ‘Statistik’, the science dealing with data about the condition of a state or community. The Oxford English Dictionary brings ‘statistics’ into English in 1787. Florence Nightingale held that ‘the thoughts and purpose of the Deity are only to be discovered by the statistical study of natural phenomena:::the application of the results of such study [is] the religious duty of man’ (Pearson, 1924).

  • The Contrasting Strategies of Almroth Wright and Bradford Hill to Capture the Nomenclature of Controlled Trials
    6 Whose Words are they Anyway? The Contrasting Strategies of Almroth Wright and Bradford Hill to Capture the Nomenclature of Controlled Trials When Almroth Wright (1861–1947) began to endure the experience common to many new fathers, of sleepless nights caused by his crying infant, he characteristically applied his physiological knowledge to the problem in a deductive fashion. Reasoning that the child’s distress was the result of milk clotting in its stomach, he added citric acid to the baby’s bottle to prevent the formation of clots. The intervention appeared to succeed; Wright published his conclusions,1 and citrated milk was eventually advocated by many paediatricians in the management of crying babies.2 By contrast, Austin Bradford Hill (1897–1991) approached his wife’s insomnia in an empirical, inductive manner. He proposed persuading his wife to take hot milk before retiring, on randomly determined nights, and recording her subsequent sleeping patterns. Fortunately for domestic harmony, he described this experiment merely as an example – actually to perform it would, he considered, be ‘exceedingly rash’.3 These anecdotes serve to illustrate the very different approaches to therapeutic experiment maintained by the two men. Hill has widely been credited as the main progenitor of the modern randomised controlled trial (RCT).4 He was principally responsible for the design of the first two published British RCTs, to assess the efficacy of streptomycin in tuberculosis5 and the effectiveness of whooping cough vaccine6 and, in particular, was responsible for the introduction of randomisation into their design.7 Almroth Wright remained, throughout his life, an implacable opponent of this ‘statistical method’, preferring what he perceived as the greater certainty of a ‘crucial experiment’ performed in the laboratory.

  • The Development of the MRC Statistical Unit, 1911-1948
    Medical History, 2000, 44: 323-340 Medical Statistics, Patronage and the State: The Development of the MRC Statistical Unit, 1911-1948 EDWARD HIGGS* The development of medical statistics based on the concepts of probability and error-theory developed by Francis Galton, Karl Pearson, George Udny Yule, R A Fisher, and their colleagues, has had a profound impact on medical science in the present century. This has been associated especially with the activities of the Medical Research Council (MRC) Statistical Unit at the London School of Hygiene and Tropical Medicine (LSHTM). It was here in 1946 that the world's first statistically rigorous clinical trial was undertaken, and where in the 1950s Austin Bradford Hill and Richard Doll revealed a statistical relationship between smoking and lung- cancer. But how and why was this key institution founded, and why were its methods probabilistic?' One might assume that the sheer brilliance of the work produced by Pearson and his statistical followers was sufficient to win over the medical profession, and to attract funding for the MRC Unit. However, one might question the extent to which an association with Pearson, and with the mathematical technicalities of his statistics, immediately endeared the fledgling discipline of biostatistics to the medical com- munity. As J Rosser Matthews has shown recently, Pearsonian statistics were only haltingly accepted by medical scientists in Britain in the 1920s and 1930s, and were little understood by medical practitioners.2 How then was such a university-based infrastructure for medical statistics established? Ultimately, of course, the Statistical * Edward Higgs, DPhil, Department of History, the statistical work on smoking, see V Berridge, University of Essex, Wivenhoe Park, Colchester, 'Science and policy: the case of postwar British C04 3SQ.

  • Austin Bradford Hill (1897-1991) [1]
    Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) Austin Bradford Hill (1897-1991) [1] By: Abboud, Carolina Keywords: Environment [2] During the twentieth century, Austin Bradford Hill researched diseases and their causes in England and developed the Bradford Hill criteria, which comprise the minimal requirements that must be met for a causal relationship to be established between a factor and a disease. Hill also suggested that researchers should randomize clinical trials to evaluate the effects of a drug or treatment by monitoring large groups of people. In addition, Hill advocated for case-control studies, in which researchers compare a group of people with a medical condition to a group without that condition to investigate the condition's possible causes. Hill's own work with clinical trials and case-control studies helped him prove that smoking caused lung cancer. The Bradford Hill criteria have also been used to establish causal links between factors and cancer, including reproductive cancers such as human papillomavirus that causes cervical cancer. Hill was born on 8 July 1897 as the third of six children to Janet Alexander and Leonard Erskine Hill in London, England. Hill's father worked as a professor of physiology at the London Hospital [3] Medical College in London, England. The previous four generations of the Hill family featured at least one member noted in the Oxford Dictionary of National Biography, an ongoing collection of notable figures in British history. Hill's father also received the title of Fellow of the Royal Society for his research on the circulation of blood in the brain.

  • The Environment and Disease: Association Or Causation?
    Observational Studies 6 (2020) 1-9 Submitted 1965; Published reprinted, 1/20 The environment and disease: association or causation? Sir Austin Bradford Hill Editor's Note: Sir Austin Bradford Hill was Professor of Medical Statistics, University of London, United Kingdom. This article was originally published in the Proceedings of the Royal Society of Medicine, May 1965, 58, 295-300. This paper is reprinted with permission of the copyright holder, Sage Publications. New comments by the following researchers follow: Peter Armitage; Mike Baiocchi; Samantha Kleinberg; James O'Malley; Chris Phillips and Joel Greenhouse; Kenneth Rothman; Herb Smith; Tyler VanderWeele; Noel Weiss; and William Yeaton. Among the objects of this newly founded Section of Occupational Medicine are: first, `to provide a means, not readily afforded elsewhere, whereby physicians and surgeons with a special knowledge of the relationship between sickness and injury and conditions of work may discuss their problems, not only with each other, but also with colleagues in other fields, by holding joint meetings with other Sections of the Society'; and second, `to make available information about the physical, chemical and psychological hazards of occupation, and in particular about those that are rare or not easily recognized'. At this first meeting of the Section and before, with however laudable intentions, we set about instructing our colleagues in other fields, it will be proper to consider a problem fundamental to our own. How in the first place do we detect these relationships between sickness, injury and conditions of work? How do we determine what are physical, chemical and psychological hazards of occupation, and in particular those that are rare and not easily recognised? There are, of course, instances in which we can reasonably answer these questions from the general body of medical knowledge.

  • Why the Father of Modern Statistics Didn't Believe Smoking Caused Cancer
    Why the Father of Modern Statistics Didn’t Believe Smoking Caused Cancer By Ben Christopher · 49,340 views · More stats Ronald A. Fisher, father of modern statistics, enjoying his pipe. *** In the summer of 1957, Ronald Fisher, one of the fathers of modern statistics, sat down to write a strongly worded letter in defense of tobacco. The letter was addressed to the British Medical Journal, which, just a few weeks earlier, had taken the editorial position that smoking cigarettes causes lung cancer. According to the journal's editorial board, the time for amassing evidence and analyzing data was over. Now, they wrote, “all the modern devices of publicity” should be used to inform the public about the perils of tobacco. According to Fisher, this was nothing short of statistically illiterate fear mongering. Surely the danger posed to the smoking masses was “not the mild and soothing weed,” he wrote, “but the organized creation of states of frantic alarm.” 2016-Christopher-Fisher-Smoking-Cancer.docx Page 1 Fisher was a well-known hothead (and an inveterate pipe smoker), but the letter and the resulting debate, which lasted until his death in 1962, was taken as a serious critique by the scientific community. After all, Ronald A. Fisher had spent much of his career devising ways to mathematically evaluate causal claims—claims exactly like the one that the British Medical Journal was making about smoking and cancer. Along the way, he had revolutionized the way that biological scientists conduct experiments and analyze data. And yet we know how this debate ends. On one of the most significant public health questions of the 20th century, Fisher got it wrong.
