Urban Health Indicator Tools of the Physical Environment: a Systematic Review

Urban health indicator (UHI) tools provide evidence about the health impacts of the physical urban environment which can be used in built environment policy and decision-making. Where UHI tools provide data at the neighborhood (and lower) scale they can provide valuable information about health inequalities and environmental deprivation. This review performs a census of UHI tools and explores their nature and characteristics (including how they represent, simplify or address complex systems) to increase understanding of their potential use by municipal built environment policy and decision-makers. We searched seven bibliographic databases, four key journals and six practitioner websites and conducted Google searches between January 27, 2016 and February 24, 2016 for UHI tools. We extracted data from primary studies and online indicator systems. We included 198 documents which identified 145 UHI tools comprising 8006 indicators, from which we developed a taxonomy. Our taxonomy classifies the significant diversity of UHI tools with respect to topic, spatial scale, format, scope and purpose. The proportions of UHI tools which measure data at the neighborhood and lower scale, and present data via interactive maps, have both increased over time. This is particularly relevant to built environment policy and decision-makers, reflects growing analytical capability and offers the potential for improved understanding of the complexity of influences on urban health (an aspect noted as a particular challenge by some indicator producers). The relation between urban health indicators and health impacts attributable to modifiable environmental characteristics is often indirect. Furthermore, the use of UHI tools in policy and decision-making appears to be limited, thus raising questions about the continued development of such tools by multiple organisations duplicating scarce resources. Further research is needed to understand the requirements of built environment policy and decision-makers, public health professionals and local communities regarding the form and presentation of indicators which support their varied objectives.     

Accounting for reasonableness: Exploring the personal internal framework affecting decisions about cancer drug funding

OBJECTIVES: Drug decision-makers are involved in developing and implementing policy, procedure and processes to support health resource allocation regarding drug treatment formularies. A variety of approaches to decision-making, including formal decision-making frameworks, have been developed to support transparent and fair priority setting. Recently, a decision tool, 'The 6-STEPPPs Tool', was developed to assist in making decisions about new cancer drugs within the public health care system. METHODS: We conducted a qualitative study, utilizing focus groups and participant observation, in order to investigate the internal frameworks that supported and challenged individual participants as they applied this decision tool within a multi-stakeholder decision process. RESULTS: We discovered that health care resource allocation engaged not only the minds of decision-makers but profoundly called on the often conflicting values of the heart. CONCLUSIONS: Objective decision-making frameworks for new drug therapies need to consider the subjective internal frameworks of decision-makers that affect decisions. Understanding the very human, internal turmoil experienced by individuals involved in health care resource allocation, sheds additional insight into how to account for reasonableness and how to better support difficult decisions through transparent, values-based resource allocation policy, procedures and processes.     

Applying research to health care policy and practice: medical and managerial views on effectiveness and the role of research

OBJECTIVES: This study explores the way in which doctors and managers think about the effectiveness of health care interventions and how this shapes the evidence they use to support decision-making. METHODS: Case studies of the introduction of three new medical technologies in nine National Health Service (NHS) hospitals and health authorities. RESULTS: Effectiveness research provides essential evidence on clinical and cost-effectiveness and is used primarily by clinicians and public health doctors for this purpose. However, research fails to provide the 'evidence' required by managerial decision-makers, whose objectives relate as much to the effect of a technology on organisational performance as on patient health and well-being. The evidence used to inform technology adoption decisions reflects the professional role and objectives of different decision-makers. CONCLUSIONS: The assumed relationship between 'research' and 'evidence' for the purpose of promoting effective health care does not take account of the wide range of objectives pursued by different health care decision-makers and the varied sources of 'evidence' they use to support their decisions.     

Correction: Using participatory design to develop (public) health decision support systems through GIS

Background  

Organizations that collect substantial data for decision-making purposes are often characterized as being 'data rich' but 'information poor'. Maps and mapping tools can be very useful for research transfer in converting locally collected data into information. Challenges involved in incorporating GIS applications into the decision-making process within the non-profit (public) health sector include a lack of financial resources for software acquisition and training for non-specialists to use such tools. This on-going project has two primary phases. This paper critically reflects on Phase 1: the participatory design (PD) process of developing a collaborative web-based GIS tool.     

Using GIS Mapping to Target Public Health Interventions: Examining Birth Outcomes Across GIS Techniques

With advances in spatial analysis techniques, there has been a trend in recent public health research to assess the contribution of area-level factors to health disparity for a number of outcomes, including births. Although it is widely accepted that health disparity is best addressed by targeted, evidence-based and data-driven community efforts, and despite national and local focus in the U.S. to reduce infant mortality and improve maternal-child health, there is little work exploring how choice of scale and specific GIS visualization technique may alter the perception of analyses focused on health disparity in birth outcomes. Retrospective cohort study. Spatial analysis of individual-level vital records data for low birthweight and preterm births born to black women from 2007 to 2012 in one mid-sized Midwest city using different geographic information systems (GIS) visualization techniques [geocoded address records were aggregated at two levels of scale and additionally mapped using kernel density estimation (KDE)]. GIS analyses in this study support our hypothesis that choice of geographic scale (neighborhood or census tract) for aggregated birth data can alter programmatic decision-making. Results indicate that the relative merits of aggregated visualization or the use of KDE technique depend on the scale of intervention. The KDE map proved useful in targeting specific areas for interventions in cities with smaller populations and larger census tracts, where they allow for greater specificity in identifying intervention areas. When public health programmers seek to inform intervention placement in highly populated areas, however, aggregated data at the census tract level may be preferred, since it requires lower investments in terms of time and cartographic skill and, unlike neighborhood, census tracts are standardized in that they become smaller as the population density of an area increases.

Citizen participation in health decision-making: past experience and future prospects

Every couple of decades governments decide that they need to involve citizens more in public decision-making processes. The significant changes that have occurred over the past decade, including a growing loss of faith in the traditional institutions of government, have once again prompted political decision-makers to explore options for enhanced citizen participation. In the health care sector, reforms occurring during the 1990s were couched in terms such as "enhanced responsiveness," "improved accountability," and "increased citizen participation." In the new millennium, governments and regional health authorities have been relatively silent on this issue. As has been the case in the past, a wide range of opinions exist about what citizen participation is and how governments should proceed. Without either conceptual clarity or practical direction, governments have been slow to articulate what they hope to achieve or how they intend to get there. The purpose of this paper is to examine the concept of citizen participation within the context of a series of basic questions from which decision-makers might draw some policy relevance. Rather than taking a particular disciplinary perspective (i.e. health promotion), the authors have chosen to review a broad spectrum of existing literature to provide a better understanding of what is known about citizen participation, both good and bad. As such, the paper is meant to be a point of departure for an informed discussion of the possibilities for improved citizen participation in health (care) decision-making.     

A randomized controlled trial of league tables and control charts as aids to health service decision-making.

OBJECTIVES: Health service managers and other decision-makers are required to act on the basis of data. Little attention has been paid to the effects of data presentation on the decisions taken. This study uses a randomized controlled trial design to investigate the effects of two forms of data presentation--league tables and control charts--on health service decision-makers. METHODS: Directors of public health in 122 health authorities in the UK were mailed three case studies and a questionnaire. The case studies showed data on variations in mortality by health service provider. The questionnaire asked them to indicate whether they would take action as a result of the data and to identify the health service providers on whom they would take action. Participants were randomly allocated to receive the same data in the form of ranked histograms (league tables) or control charts. MAIN OUTCOME MEASURE: The percentage of participants who would take action on health service providers. RESULTS: Fifty-seven questionnaires were returned. For each case study, respondents receiving data as league tables stated they would take action on significantly more health service providers than those receiving data as control charts: for the first case study, the percentages were 3.3% versus 1.8% (P < 0.001) for league tables and control charts, respectively; for the second case study, 15.9% versus 6.7% (P = 0.029), respectively; and for the third, 5.9% versus 0.7% (P = 0.002), respectively. Respondents receiving data as league tables were significantly more likely to request further information on case mix. CONCLUSIONS: Compared with league tables, health service decision-makers identify fewer outliers for further action when performance data are presented as control charts. They also reduce the tendency to request further information. Using control charts rather than league tables for the routine presentation of comparative data would reduce over-investigation of unusual performance.     

Exploring the role of GIS during community health assessment problem solving: experiences of public health professionals

Background  

A Community health assessment (CHA) involves the use of Geographic Information Systems (GIS) in conjunction with other software to analyze health and population data and perform numerical-spatial problem solving. There has been little research on identifying how public health professionals integrate this software during typical problem solving scenarios. A better understanding of this is needed to answer the "What" and the "How". The "What" identifies the specific software being used and the "How" explains the way they are integrated together during problem solving steps. This level of understanding will highlight the role of GIS utilization during problem solving and suggest to developers how GIS can be enhanced to better support data analysis during community health assessment.     

Measuring the impact of health research

Measuring the decision-making impact of applied health research should constitute a core function for many research funders and research organizations. Different target audiences warrant different measures of impact. The target audiences for applied health research include the general public, patients (and their families), clinicians, managers (in hospitals, regional health authorities and health plans), research and development officers (in biotechnology firms) and public policy-makers (i.e. elected officials, political staff and civil servants). Making meaningful assessments within peer groups that fund or produce similar types of research knowledge for similar types of target audiences makes more sense than a one-size-fits-all approach to impact assessment. User-pull and interactive measures of impact (i.e. measures of cultural shifts that would facilitate the on-going use of research knowledge to inform decision-making) can supplement more traditional producer-push measures that assess researchers' active efforts to inform decision-making and the outcome of these efforts. Cultural shifts may include the creation of a research-attuned culture among decision-makers and a decision-relevant culture among researchers. Moving beyond whether research was used to examine how it was used is also important. Research knowledge may be used in instrumental, conceptual or symbolic ways. These actions, coupled with on-going refinements to the proposed assessment tool as research evidence evolves, would take us a long way towards assessment and accountability in the health sector.     

Visualization and exploratory analysis of epidemiologic data using a novel space time information system

The term "Geographic Information Systems" (GIS) has been added to MeSH in 2003, a step reflecting the importance and growing use of GIS in health and healthcare research and practices. GIS have much more to offer than the obvious digital cartography (map) functions. From a community health perspective, GIS could potentially act as powerful evidence-based practice tools for early problem detection and solving. When properly used, GIS can: inform and educate (professionals and the public); empower decision-making at all levels; help in planning and tweaking clinically and cost-effective actions, in predicting outcomes before making any financial commitments and ascribing priorities in a climate of finite resources; change practices; and continually monitor and analyse changes, as well as sentinel events. Yet despite all these potentials for GIS, they remain under-utilised in the UK National Health Service (NHS). This paper has the following objectives: (1) to illustrate with practical, real-world scenarios and examples from the literature the different GIS methods and uses to improve community health and healthcare practices, e.g., for improving hospital bed availability, in community health and bioterrorism surveillance services, and in the latest SARS outbreak; (2) to discuss challenges and problems currently hindering the wide-scale adoption of GIS across the NHS; and (3) to identify the most important requirements and ingredients for addressing these challenges, and realising GIS potential within the NHS, guided by related initiatives worldwide. The ultimate goal is to illuminate the road towards implementing a comprehensive national, multi-agency spatio-temporal health information infrastructure functioning proactively in real time. The concepts and principles presented in this paper can be also applied in other countries, and on regional (e.g., European Union) and global levels.     

Visual localisation of community health needs to rational decision-making in public health services

The objectives were to visualise the locations of community health needs and to develop a community health needs assessment geographic information system (GIS) for rational decision-making in public health services. We compiled census data, digital data of basic planning maps, digital data of topographic maps, contents of registers of medical and welfare facilities, and statistics of establishments into a geographical database; visualised geographical distributions of specific community health needs by integrating sets of indicators to reflect individual needs; and quantified their clustering by the nearest neighbour method. The database aggregated 3400 items of demographic, life and environmental factors. Thematic maps and clustering values showed different patterns of geographical distribution of the individual community needs. Means to match needs with services in smaller geographical units were discussed. This GIS will support appropriate resource allocation, intersectoral collaboration and greater transparency in planning and implementing services, by visualising locations of community health needs.     

A spatial decision support tool for estimating population catchments to aid rural and remote health service allocation planning

There is mounting pressure on healthcare planners to manage and contain costs. In rural regions, there is a particular need to rationalize health service allocation to ensure the best possible coverage for a dispersed population. Rural health administrators need to be able to quantify the population affected by their allocation decisions and, therefore, need the capacity to incorporate spatial analyses into their decision-making process. Spatial decision support systems (SDSS) can provide this capability. In this article, we combine geographical information systems (GIS) with a web-based graphical user interface (webGUI) in a SDSS tool that enables rural decision-makers charged with service allocation, to estimate population catchments around specific health services in rural and remote areas. Using this tool, health-care planners can model multiple scenarios to determine the optimal location for health services, as well as the number of people served in each instance.     

COMMENTARY: “Is the Gap in Policy Processes Towards Better Food Security and Nutrition Interventions Mainly a Gap Between Knowledge and Action?”

Food and nutrition issues get little policy attention from decision-makers. The lack of action is not due to a lack of knowledge by the latter. Other gaps are at the root—gaps that denote a deliberate choice of not attending to food and nutrition matters. It is ultimately power relations that affect policy choices. It is here contended that policy processes can only be fully understood if analyzed politically. Consciousness raising and social mobilization are indispensable to influence policy processes. Research organizations have hardly engaged in this consciousness-raising; most of them are rather conservative. They think that if decision-makers have more and better knowledge they will indeed take urgently needed decisions; but they never go against their own interests. What is missing, and is argued in favor of here, is the need for structural changes that address the basic causes of preventable hunger and malnutrition by organizing pressure from below—thus the importance of empowering beneficiaries.     

Ethical Frameworks in Public Health Decision-Making: Defending a Value-Based and Pluralist Approach

A number of ethical frameworks have been proposed to support decision-making in public health and the evaluation of public health policy and practice. This is encouraging, since ethical considerations are of paramount importance in health policy. However, these frameworks have various deficiencies, in part because they incorporate substantial ethical positions. In this article, we discuss and criticise a framework developed by James Childress and Ruth Bernheim, which we consider to be the state of the art in the field. Their framework distinguishes aims, such as the promotion of public health, from constraints on the pursuit of those aims, such as the requirement to avoid limitations to liberty, or the requirement to be impartial. We show how this structure creates both theoretical and practical problems. We then go on to present and defend a more practical framework, one that is neutral in avoiding precommitment to particular values and how they ought to be weighted. We believe ethics is at the very heart of such weightings and our framework is developed to reflect this belief. It is therefore both pluralist and value-based. We compare our new framework to Childress and Bernheim’s and outline its advantages. It is justified by its impetus to consider a wide range of alternatives and its tendency to direct decisions towards the best alternatives, as well as by the information provided by the ranking of alternatives and transparent explication of the judgements that motivate this ranking. The new framework presented should be useful to decision-makers in public health, as well as being a means to stimulate further reflection on the role of ethics in public health.     

Coping with uncertainty: decisions and resources within health authorities

Summary This article reports on a two-year study which looked at decision-making in two Scottish health boards. The study, which focused on the allocation of development funds (growth monies), is about understanding and not about reform. It was prompted by: (1) a dearth of knowledge concerning the dynamics of decision-making in the National Health Service (NHS) at local level, especially since the 1974 reorganisation of the Service; and (2) a desire to understand the factors at local level which might help to explain the persistence of resource imbalances between different sectors of health care despite successive attempts by central government to remove them. The study suggests that, contrary to much popular opinion, decision-making in the NHS is decentralised - the two health boards featured in the research possessed a large measure of influence over the services they provided. Aside from rational and incremental theories of decision-making which were of value in compre-hending the decision process observed, the notion of puzzlement as a factor determining decision outcomes was found to be of particular value in the context of the allocation of development funds. The main study findings were: (1) that a policy of appeasing competing, and equally demanding, interests rendered change exceptional although not impossible, as was shown by the emphasis placed upon community health services; (2) that various constraints, both internal and external, operated on decision-makers; and (3) that a number of coping strategies were adopted by decision-makers in order to structure their uncertain and unpredictable environment and to manage the constraints on them.     

Economic evaluations of alcohol prevention interventions: Is the evidence sufficient? A review of methodological challenges

Public health interventions have unique characteristics compared to health technologies, which present additional challenges for economic evaluation (EE). High quality EEs that are able to address the particular methodological challenges are important for public health decision-makers. In England, they are even more pertinent given the transition of public health responsibilities in 2013 from the National Health Service to local government authorities where new agents are shaping policy decisions.Addressing alcohol misuse is a globally prioritised public health issue. This article provides a systematic review of EE and priority-setting studies for interventions to prevent and reduce alcohol misuse published internationally over the past decade (2006–2016). This review appraises the EE and priority-setting evidence to establish whether it is sufficient to meet the informational needs of public health decision-makers.619 studies were identified via database searches. 7 additional studies were identified via hand searching journals, grey literature and reference lists. 27 met inclusion criteria. Methods identified included cost-utility analysis (18), cost-effectiveness analysis (6), cost-benefit analysis (CBA) (1), cost-consequence analysis (CCA) (1) and return-on-investment (1). The review identified a lack of consideration of methodological challenges associated with evaluating public health interventions and limited use of methods such as CBA and CCA which have been recommended as potentially useful for EE in public health. No studies using other specific priority-setting tools were identified.     

Adolescent Pediatric Decision-Making: A Critical Reconsideration in the Light of the Data

Adolescents present a puzzle. There are foundational unclarities about how they should be regarded as decision-makers. Although superficially adolescents may appear to have mature decisional capacity, their decision-making is in many ways unlike that of adults. Despite this seemingly obvious fact, a concern for the claims of autonomy has led to the development of the legal doctrine of the mature minor. This legal construct considers adolescents, as far as possible, as equivalent to adults for the purpose of medical decision-making. The movement to support independent decision-making by adolescents through providing information to them and securing their consent apart from their parents is encouraged by those legal understandings that hold that unemancipated minors should generally be considered as possessing effective decisional capacity. Such legal structures, however, do not adequately take account of the wide variations in adolescent capacities, the immaturity of most adolescent decision-makers, or the important contributions made by parents to the development of their adolescents through parental partnering in the adolescent’s decision-making. The data available indicate that in general adolescents should be regarded as apprentice decision-makers who should make decisions in collaboration with their parents until at least the age of 18. Steps should not be taken pre-emptively to isolate adolescents from the guidance of their parents. As a general rule, what Piker has referred to as “collaborative paternalism” appears most likely both to protect adolescents from their own untoward choices, while also very importantly helping them with parental guidance to develop into mature decision-makers with the capacity to make medical choices on their own.     

“I keep hearing reports on the news that it's a real problem at the moment”: Public health nurses’ understandings of sexting practices among young people

Over the past decade, the potential harms regarding young people's use of technology have attracted mounting political, media and research attention worldwide. One practice engaged in by many young people is that of “sexting” and the sharing of partially, or complete nude images (“selfies”). Such images are not always retained within private spaces and are prone to be shared, with significant psychosocial consequences for young people involved. A significant risk is the hidden nature of some online interactions, with potential for grooming and child sexual exploitation. As key professionals working with young people, public health nurses have potential to educate and explore the risks with them. Yet to date, to our knowledge there has been no research in relation to public health nurses’ understandings of the practices involved or their potential harms. A qualitative study was undertaken drawing theoretically on the common‐sense model (CSM) to frame the analysis. Eighteen semi‐structured interviews were conducted with public health nurses in a region of England in 2016. Data were analysed through thematic analysis, and mapped to the five domains of CSM. Public health nurses’ understandings of young people's sexting practices were shaped largely by media reports, rather than scientific, disciplinary knowledge. Sexting did not resonate with many public health nurses’ own experiences of being a young person and was therefore difficult to understand. All were able to express an opinion about the causes and consequences of sexting and we present these as a “perceived hierarchy of risk”. All public health nurses acknowledged the importance of their role in dealing with harm reduction associated with sexting among young people, but they need education and support to do this effectively and confidently. Findings can be transferred carefully to many contexts and countries because sexting is a practice among young people that transcends geographical boundaries.
