Prioritization of practical solutions for the vibrational health risk reduction of mining trucks using fuzzy decision making

Abstract

The goal of this article was to prioritize the practical solutions for vibrational health risk reduction of truck drivers during mining operation using the multicriteria decision-making (MCDM) techniques. Mining trucks require special consideration because of their specific suspension system, large size, payload capacity, and off-road conditions of mining. In most cases, it is not easy for decision makers to compute verbal and linguistic variables, whose values are expressed in linguistic terms. These uncertainties and ambiguities are well interpreted by using fuzzy set theory. In this study, the MCDM methods were used under fuzzy environment. As a result, seat suspension maintenance was offered as the best solution to attenuate the vibrations and decrease the injuries related to the WBV exposure. The driver training, haul road construction and maintenance, lighting and visibility improvement and work organization were found as the other solutions, respectively.     

Evidence-based decision making in public health.

A stronger focus on evidence-based decision making in day-to-day public health practice is needed. This article describes the rationale for this need, including (1) the inter-relationships between evidence-based medicine and evidence-based public health (EBPH); (2) commonly used analytic tools and processes; (3) keys to when public health action is warranted; (4) a strategic, six-step approach to more analytic decision making; and (5) summary barriers and opportunities for widespread implementation of EBPH. The approach outlined is being tested through a series of courses for mid-level managers in the Missouri Department of Health--initial results from a pilot test are encouraging. It is hoped that the greater use of an evidence-based framework in public health will lead to more effective programs.     

A Bayesian approach to health project estimation.

This paper illustrates how a Bayesian statistical approach was used to estimate the outcomes of the National Tuberculosis Program in India. Such an estimate, it is argued, is necessary for a proper judgement about a project's social usefulness. The process of medical care delivery is reduced to a set of conditioned probabilities. The numbers are estimated using as source material medical records, the results of medical research, and the opinion of experts. Bayesian methods of estimation are used and their value is discussed. The final discussion contains a brief treatment of the role of project analysis in public decision making. The place of Bayesian methods in project analysis is briefly illustrated, demonstrating their operational value in the field of public health decision making.     

Who Opts out of the Statutory Health Insurance? A Discrete Time Hazard Model for Germany

The coexistence of social health insurance and private health insurance in Germany is subject to intense public debate. As only few have the opportunity to choose between the two systems, they are often regarded as privileged by the health insurance system. Applying a hazard model in discrete time, this paper examines the role of incentives set by the regulatory framework and the influence of individual personality characteristics on the decision to opt out of the statutory system. To address potential endogeneity of one of the key explanatory variables, an instrumental variable approach is also applied. The estimation results yield robust evidence on the choice of health insurance type that is consistent with pragmatic decision making, with both incentives set by regulation and personality traits as relevant determinants.

A systematic review of decision support needs of parents making child health decisions

Objective  To identify the decision support needs of parents attempting to make an informed health decision on behalf of a child.
Context  The first step towards implementing patient decision support is to assess patients' information and decision-making needs.
Search strategy  A systematic search of key bibliographic databases for decision support studies was performed in 2005. Reference lists of relevant review articles and key authors were searched. Three relevant journals were hand searched.
Inclusion criteria  Non-intervention studies containing data on decision support needs of parents making child health decisions.
Data extraction and synthesis  Data were extracted on study characteristics, decision focus and decision support needs. Studies were quality assessed using a pre-defined set of criteria. Data synthesis used the UK Evidence for Policy and Practice Information and Co-ordinating Centre approach.
Main results  One-hundred and forty nine studies were included across various child health decisions, settings and study designs. Thematic analysis of decision support needs indicated three key issues: (i) information (including suggestions about the content, delivery, source, timing); (ii) talking to others (including concerns about pressure from others); and (iii) feeling a sense of control over the process that could be influenced by emotionally charged decisions, the consultation process, and structural or service barriers. These were consistent across decision type, study design and whether or not the study focused on informed decision making.     

Creating an organizational culture for evidence-informed decision making

A public health department in Ontario, Canada, set a 10-year strategic direction for evidence-informed decision making, defined as the systematic application of research evidence to program decisions. The multifaceted approach has identified eight key lessons for leadership, funding, infrastructure, staff development, partnerships, and change management. Results after 4 years include systematic and transparent application of research to >15 program decisions and, increasingly, evidence-informed decision making as a cultural norm.     

Global priority setting for Cochrane systematic reviews of health promotion and public health research

BACKGROUND: Systematic reviews of health promotion and public health interventions are increasingly being conducted to assist public policy decision making. Many intra-country initiatives have been established to conduct systematic reviews in their relevant public health areas. The Cochrane Collaboration, an international organisation established to conduct and publish systematic reviews of healthcare interventions, is committed to high quality reviews that are regularly updated, published electronically, and meeting the needs of the consumers. AIMS: To identify global priorities for Cochrane systematic reviews of public health topics. METHODS: Systematic reviews of public health interventions were identified and mapped against global health risks. Global health organisations were engaged and nominated policy-urgent titles, evidence based selection criteria were applied to set priorities. RESULTS: 26 priority systematic review titles were identified, addressing interventions such as community building activities, pre-natal and early infancy psychosocial outcomes, and improving the nutrition status of refugee and displaced populations. DISCUSSION: The 26 priority titles provide an opportunity for potential reviewers and indeed, the Cochrane Collaboration as a whole, to address the previously unmet needs of global health policy and research agencies.     

Comprehensive assessment in public health

The Italian health system has been completely public for 25 years; it is now adopting a federal structure conferring to the single regions a leading role in public health management. Therefore clear evaluation methods and tools need to be adopted in order to guarantee equity-based decision making. Multidimensional evaluation, a method first developed in the geriatric setting, represents an extremely useful tool both to establish the best profile of assistance and to guide the management of different services. It is mainly used to evaluate health status and needs for assistance within non self-sufficient populations, largely composed of the elderly. Currently available assessment tools reveal different approaches, goals and level of accuracy. The authors have examined and compared 21 different multidimensional assessment tools adopted in Italy with a standardized method based on pre-established data collection and evaluation criteria. Both quantitative (number of items used for every single dimension or sub-dimension) and quali-quantitative aspects (level of detail for every single dimension or sub-dimension) are included in the analysis. Tools were also evaluated according to the degree of fulfilment of certain fixed requirements. In the authors' opinion, given a specific assistance setting and its users, once the goals and requirements of the evaluation instrument are clearly defined, adopting this methodology--defined as "Progressive exclusion method for easier visualization of criteria correspondence and quali-quantitative aspects", would help to identify the most suitable assessment tools to be used. The authors hope that, on a regional level, the public health system will make a greater use of homogeneous multidimensional comprehensive assessment tools in order to foster both a uniform approach towards the needs for assistance and transparent criteria of resources allocation in public health services.     

Factors of the innovation, organization, environment, and individual that predict the influence five systematic reviews had on public health decisions.

OBJECTIVE: To determine the extent to which systematic reviews of public health interventions influenced public health decisions and which factors were associated with influencing these decisions. METHODS: This cross-sectional follow-up survey evaluated the use of five systematic reviews in public health decision making. Independent variables included characteristics of the innovation, organization, environment, and individual. Primary data were collected using a telephone survey and a self-administered organizational demographics questionnaire. Public health decision makers in all 41 public health units in Ontario were invited to participate in the study. Multiple linear regression analyses on the five program decisions were conducted. RESULTS: The systematic reviews were perceived as having the greatest amount of influence on decisions related to program justification and program planning, and the least influence on program evaluation decisions. The greater the perception that one's organization valued the use of research evidence for decision making and that ongoing training in the critical appraisal of research literature was provided, the greater the perception of the influence the systematic review had on public health decisions. CONCLUSIONS: Organizational characteristics are important predictors of the use of systematic reviews in public health decision making. Future dissemination strategies need to promote the value of using systematic reviews for program decision making as well as promote ongoing training in critical appraisal among intended users in Ontario.     

Exploring ethical terrain in public health.

Public health is rife with ethical challenges. Ethical principles and values are intrinsic to public health decision making, although they are generally not identified explicitly. One purpose of this article is to discuss public health goals as an ethical/value concern with attention to values that do and should underlie health care in the United States. A second purpose is to introduce frameworks for public health decision making that incorporate ethical considerations into community and health promotion perspectives of public health decision makers. Public health policy makers and providers are urged to explore ethical/value dimensions of the health care system and to use the ethical frameworks in their decision making, expanding the more individualistic perspective of traditional bioethics.     

The CAPACITI Decision-Support Tool for National Immunization Programs

ObjectivesImmunization programs in low-income and middle-income countries (LMICs) are faced with an ever-growing number of vaccines of public health importance recommended by the World Health Organization, while also financing a greater proportion of the program through domestic resources. More than ever, national immunization programs must be equipped to contextualize global guidance and make choices that are best suited to their setting. The CAPACITI decision-support tool has been developed in collaboration with national immunization program decision makers in LMICs to structure and document an evidence-based, context-specific process for prioritizing or selecting among multiple vaccination products, services, or strategies.MethodsThe CAPACITI decision-support tool is based on multi-criteria decision analysis, as a structured way to incorporate multiple sources of evidence and stakeholder perspectives. The tool has been developed iteratively in consultation with 12 countries across Africa, Asia, and the Americas.ResultsThe tool is flexible to existing country processes and can follow any type of multi-criteria decision analysis or a hybrid approach. It is structured into 5 sections: decision question, criteria for decision making, evidence assessment, appraisal, and recommendation. The Excel-based tool guides the user through the steps and document discussions in a transparent manner, with an emphasis on stakeholder engagement and country ownership.ConclusionsPilot countries valued the CAPACITI decision-support tool as a means to consider multiple criteria and stakeholder perspectives and to evaluate trade-offs and the impact of data quality. With use, it is expected that LMICs will tailor steps to their context and streamline the tool for decision making.     

Making Good Decisions in Healthcare with Multi-Criteria Decision Analysis: The Use,Current Research and Future Development of MCDA

Healthcare decision making is usually characterized by a low degree of transparency. The demand for transparent decision processes can be fulfilled only when assessment, appraisal and decisions about health technologies are performed under a systematic construct of benefit assessment. The benefit of an intervention is often multidimensional and, thus, must be represented by several decision criteria. Complex decision problems require an assessment and appraisal of various criteria; therefore, a decision process that systematically identifies the best available alternative and enables an optimal and transparent decision is needed. For that reason, decision criteria must be weighted and goal achievement must be scored for all alternatives. Methods of multi-criteria decision analysis (MCDA) are available to analyse and appraise multiple clinical endpoints and structure complex decision problems in healthcare decision making. By means of MCDA, value judgments, priorities and preferences of patients, insurees and experts can be integrated systematically and transparently into the decision-making process. This article describes the MCDA framework and identifies potential areas where MCDA can be of use (e.g. approval, guidelines and reimbursement/pricing of health technologies). A literature search was performed to identify current research in healthcare. The results showed that healthcare decision making is addressing the problem of multiple decision criteria and is focusing on the future development and use of techniques to weight and score different decision criteria. This article emphasizes the use and future benefit of MCDA.     

Perils and possibilities: achieving best evidence from focus groups in public health research

Objective: Focus group research is often seen as a cost-effective way of gathering evidence from multiple research participants about the diversity of their views, experiences or beliefs. Our objective is to argue that focus group research only fulfils its potential if analysis of individual views is extended to include analysis of interaction between participants, so that we learn more why people hold these views.
Approach: We outline the literature on focus group research, contrasting the 'quick-and-easy' approach with the demands of studies that are designed, conducted and analysed in a methodologically rigorous way to yield high quality public health evidence.
Conclusion: Well-conducted focus groups contribute good evidence for public health decision making. The challenges of conducting high-quality studies should not be underestimated, and must involve rigorous analysis of both interaction and content.     

Marcos GRADE de la evidencia a la decisión (EtD): un enfoque sistemático y transparente para tomar decisiones sanitarias bien informadas. 1: Introducción

Clinicians, guideline developers, and policymakers sometimes neglect important criteria, give undue weight to criteria, and do not use the best available evidence to inform their judgments. Explicit and transparent systems for decision making can help to ensure that all important criteria are considered and that decisions are informed by the best available research evidence. The GRADE Working Group has developed Evidence to Decision (EtD) frameworks for the different type of recommendations or decisions. The purpose of EtD frameworks is to help people use evidence in a structured and transparent way to inform decisions in the context of clinical recommendations, coverage decisions, and health system or public health recommendations and decisions. EtD frameworks have a common structure that includes formulation of the question, an assessment of the evidence, and drawing conclusions, though there are some differences between frameworks for each type of decision. EtD frameworks inform users about the judgments that were made and the evidence supporting those judgments by making the basis for decisions transparent to target audiences. EtD frameworks also facilitate dissemination of recommendations and enable decision makers in other jurisdictions to adopt recommendations or decisions, or adapt them to their context. This article is a translation of the original article published in British Medical Journal. The EtD frameworks are currently used in the Clinical Practice Guideline Programme of the Spanish National Health System, co-ordinated by GuíaSalud.     

A knowledge management tool for public health: health-evidence.ca

Background

The ultimate goal of knowledge translation and exchange (KTE) activities is to facilitate incorporation of research knowledge into program and policy development decision making. Evidence-informed decision making involves translation of the best available evidence from a systematically collected, appraised, and analyzed body of knowledge. Knowledge management (KM) is emerging as a key factor contributing to the realization of evidence-informed public health decision making. The goal of health-evidence.ca is to promote evidence-informed public health decision making through facilitation of decision maker access to, retrieval, and use of the best available synthesized research evidence evaluating the effectiveness of public health interventions.

Methods

The systematic reviews that populate health evidence.ca are identified through an extensive search (1985-present) of 7 electronic databases: MEDLINE, EMBASE, CINAHL, PsycINFO, Sociological Abstracts, BIOSIS, and SportDiscus; handsearching of over 20 journals; and reference list searches of all relevant reviews. Reviews are assessed for relevance and quality by two independent reviewers. Commonly-used public health terms are used to assign key words to each review, and project staff members compose short summaries highlighting results and implications for policy and practice.

Results

As of June 2010, there are 1913 reviews in the health-evidence.ca registry in 21 public health and health promotion topic areas. Of these, 78% have been assessed as being of strong or moderate methodological quality. Health-evidence.ca receives approximately 35,000 visits per year, 20,596 of which are unique visitors, representing approximately 100 visits per day. Just under half of all visitors return to the site, with the average user spending six minutes and visiting seven pages per visit. Public health nurses, program managers, health promotion workers, researchers, and program coordinators are among the largest groups of registered users, followed by librarians, dieticians, medical officers of health, and nutritionists. The majority of users (67%) access the website from direct traffic (e.g., have the health-evidence.ca webpage bookmarked, or type it directly into their browser).

Conclusions

Consistent use of health-evidence.ca and particularly the searching for reviews that correspond with current public health priorities illustrates that health-evidence.ca may be playing an important role in achieving evidence-informed public health decision making.     

Ethical issues in public health: a qualitative study of public health practice in Scotland

STUDY OBJECTIVE: To identify ethical issues encountered by staff in the development and implementation of public health activities at two sites in Scotland. DESIGN: Qualitative research study involving face to face semi-structured interviews with participants. SETTING: A public health directorate in a National Health Service Trust, and a public health demonstration project in child health. PARTICIPANTS: Health promotion specialists, managers, nurses, public health consultants and specialists, researchers, trainees, and other public health staff. MAIN RESULTS: Three main categories of ethical issues were identified: paternalism, responsibilities, and ethical decision making. Consulting with the community and sharing information raised issues of paternalism and honesty. Participants identified multiple and sometimes conflicting responsibilities. Barriers to fulfilling responsibilities included meeting targets, working with partners, and political influences. Defining the limits of responsibilities posed challenges. Participants identified values for ideal decision making, but lack of time often led to a more pragmatic approach. CONCLUSION: These empirical findings complement and extend existing discussions of public health ethics, emphasising the complex nature of ethical issues in public health. The implications for public health policy and future research are discussed.     

Meningococcal C disease epidemic in Galicia 1996: the decision making process

In this article we describe the decision making process used to choose the best alternative for bringing under control an epidemic of meningococcal C disease, which occurred in Galicia in 1996. In the decision making process, we used a methodology which consisted on the identification and definition of a problem, in order to identify alternative solutions and to select one, and finally implement and evaluate it. The health problem was detected studying the data obtained from a survey conducted following an outbreak of meningococcal C disease in february 1995 and from the active epidemiological surveillance system created thereafter. Because this was a new, complex and severe problem, with far-reaching social consequences, critical for our organization, and with long-term implications, and because it was considered important to take the decision as objectively as possible and to clearly explain it, the methodology chosen to solve the problem was a non-programmed, multicriteria making decision process, carried out by a working group using a criterion weighting approach. This working group was created within the General Directorate of Public Health, composed of specialist and of people responsible for the different areas involved. The working group put into practice the different steps of the methodology. The assessment criteria and their respective weights were: effect (efficacy measured by the number of cases we could have prevented if the alternatives were applied in the previous season) 40%; cost (in millions of pesetas) 15%; acceptability (acceptance of and response to each strategy from different groups: general population, health care professionals, other Administrations with competency in Public Health) 30%; and coherence (adherence to the currently accepted strategies for disease control in other countries)15%. When these criteria were applied to the ten alternatives considered, a score was obtained for each one of them. The highest scoring alternative corresponded to the massive vaccination of the total population of Galicia between 18 months and 19 years of age.     

Improving the contribution of public health to NHS decision making: development of an instrument

Recent policy pronouncements have raised expectations that public health practitioners will be increasingly involved in NHS decision making. This is a complex task which requires the bringing together of appropriate data and values. The authors developed an instrument, to aid decision making, which seeks to make explicit the values held by key health decision makers at local level. We report on the evolution of the project and the development of the instrument. This work is then placed within the context of the current renaissance in British public health, as the instrument could be useful when public health issues are being decided by or with partners within the National Health Service (NHS), the local authorities or the wider community.     

Information and involvement

This article discusses the beliefs that provision of good quality information is the key to (a) successful and satisfying involvement of patients in their own decision‐making and (b) involvement of lay people in the research process, in debate and other involvement in wider health issues. Education of children, health professionals, the public and the media is advocated, enabling critical appraisal skills and good quality health information to lead to improved involvement of citizens in health‐care decisions of all kinds, both individual and societal. Examples of individual, group and specific group involvement through research projects, debates about screening, Citizens’ Juries, etc. are used to illustrate benefits to patients and to health provision in general.
