Taking up national safety alerts to improve patient safety in hospitals: The perspective of healthcare quality and risk managers.

BACKGROUND National safety alert systems publish relevant information to improve patient safety in hospitals. However, the information has to be transformed into local action to have an effect on patient safety. We studied three research questions: How do Swiss healthcare quality and risk managers (qm/rm(1)) see their own role in learning from safety alerts issued by the Swiss national voluntary reporting and analysis system? What are their attitudes towards and evaluations of the alerts, and which types of improvement actions were fostered by the safety alerts? METHODS A survey was developed and applied to Swiss healthcare risk and quality managers, with a response rate of 39 % (n=116). Descriptive statistics are presented. RESULTS The qm/rm disseminate and communicate with a broad variety of professional groups about the alerts. While most respondents felt that they should know the alerts and their contents, only a part of them felt responsible for driving organizational change based on the recommendations. However, most respondents used safety alerts to back up their own patient safety goals. The alerts were evaluated positively on various dimensions such as usefulness and were considered as standards of good practice by the majority of the respondents. A range of organizational responses was applied, with disseminating information being the most common. An active role is related to using safety alerts for backing up own patient safety goals. CONCLUSIONS To support an active role of qm/rm in their hospital's learning from safety alerts, appropriate organizational structures should be developed. Furthermore, they could be given special information or training to act as an information hub on the issues discussed in the alerts.

Predictive technology and natural hazards: Risk for Australian planning authorities?

Purpose The object of this paper is to examine whether the improvements in technology that enhance community understanding of the frequency and severity of natural hazards also increased the risk of potential liability of planning authorities in negligence. In Australia, the National Strategy imposes a resilience based approach to disaster management and stresses that responsible land use planning can reduce or prevent the impact of natural hazards upon communities. Design/methodology/approach This paper analyses how the principles of negligence allocate responsibility for loss suffered by a landowner in a hazard prone area between the landowner and local government. Findings The analysis in this paper concludes that despite being able to establish a causal link between the loss suffered by a landowner and the approval of a local authority to build in a hazard prone area, it would be in the rarest of circumstances a negligence action may be proven. Research limitations/implications The focus of this paper is on planning policies and land development, not on the negligent provision of advice or information by the local authority. Practical implications This paper identifies the issues a landowner may face when seeking compensation from a local authority for loss suffered due to the occurrence of a natural hazard known or predicted to be possible in the area. Originality/value The paper establishes that as risk managers, local authorities must place reliance upon scientific modelling and predictive technology when determining planning processes in order to fulfil their responsibilities under the National Strategy and to limit any possible liability in negligence.

Implementing Risk Management::A Study of Major Malaysian Corporations

This study presents findings from a series of interviews with Risk Managers and/or Chief Risk Officers from major Malaysian companies about the prerequisites for the effective implementation of Risk Management programmes. The interviews highlight the importance of a number of factors, including: a strong commitment from the Board of Directors and Management in general, a desire for an appropriate risk culture, the development of formal Risk Management frameworks and policies, a recognition of the importance of risk communication, the appointment of a Chief Risk Officer (CRO) and the development of a complementary system of internal audit.

Application of the BRAFO-tiered approach for benefit-risk assessment to case studies on natural foods

There is evidence that consumption of fish, especially oily fish, has substantial beneficial effects on health. In particular an inverse relationship of oily fish intake to coronary heart disease incidence has been established. These beneficial effects are ascribed to fish oil components including long chain ω-3 polyunsaturated fatty acids. On the other hand it should be noted that oily fish also contains hazardous substances such as dioxins, PCBs and methylmercury. Soy consumption has been associated with potential beneficial and adverse effects. The claimed benefits include reduced risk of cardiovascular disease; osteoporosis, breast and prostate cancer whereas potential adverse effects include impaired thyroid function, disruption of sex hormone levels, changes in reproductive function and increased breast cancer risk The two cases of natural foods highlight the need to consider both risks and benefits in order to establish the net health impact associated to the consumption of specific food products. Within the Sixth Framework programme of the European Commission, the BRAFO project was funded to develop a framework that allows for the quantitative comparison of human health risks and benefits in relation to foods and food compounds. This paper describes the application of the developed framework to two natural foods, farmed salmon and soy protein. We conclude that the BRAFO methodology is highly applicable to natural foods. It will help the benefit-risk managers in selecting the appropriate dietary recommendations for the population.

Análise empírica do value-at-risk por simulação histórica com atualização de volatilidade para fundos de ações no Brasil

Há mais de uma década, o Value-at-Risk (VaR) é utilizado por instituições financeiras e corporações não financeiras para controlar o risco de mercado de carteiras de investimentos. O fato dos métodos paramétricos assumirem a hipótese de normalidade da distribuição de retornos dos fatores de risco de mercado, leva alguns gestores de risco a utilizar métodos por simulação histórica para calcular o VaR das carteiras. A principal crítica à simulação histórica tradicional é, no entanto, dar o mesmo peso na distribuição à todos os retornos encontrados no período. Este trabalho testa o modelo de simulação histórica com atualização de volatilidade proposto por Hull e White (1998) com dados do mercado brasileiro de ações e compara seu desempenho com o modelo tradicional. Os resultados mostraram um desempenho superior do modelo de Hull e White na previsão de perdas para as carteiras e na sua velocidade de adaptação à períodos de ruptura da volatilidade do mercado.

Science-policy in environmental and health risk assessment: if we cannot do without, can we do better?

How can empirical evidence of adverse effects from exposure to noxious agents, which is often incomplete and uncertain, be used most appropriately to protect human health? We examine several important questions on the best uses of empirical evidence in regulatory risk management decision-making raised by the US Environmental Protection Agency (EPA)'s science-policy concerning uncertainty and variability in human health risk assessment. In our view, the US EPA (and other agencies that have adopted similar views of risk management) can often improve decision-making by decreasing reliance on default values and assumptions, particularly when causation is uncertain. This can be achieved by more fully exploiting decision-theoretic methods and criteria that explicitly account for uncertain, possibly conflicting scientific beliefs and that can be fully studied by advocates and adversaries of a policy choice, in administrative decision-making involving risk assessment. The substitution of decision-theoretic frameworks for default assumption-driven policies also allows stakeholder attitudes toward risk to be incorporated into policy debates, so that the public and risk managers can more explicitly identify the roles of risk-aversion or other attitudes toward risk and uncertainty in policy recommendations. Decision theory provides a sound scientific way explicitly to account for new knowledge and its effects on eventual policy choices. Although these improvements can complicate regulatory analyses, simplifying default assumptions can create substantial costs to society and can prematurely cut off consideration of new scientific insights (e.g., possible beneficial health effects from exposure to sufficiently low 'hormetic' doses of some agents). In many cases, the administrative burden of applying decision-analytic methods is likely to be more than offset by improved effectiveness of regulations in achieving desired goals. Because many foreign jurisdictions adopt US EPA reasoning and methods of risk analysis, it may be especially valuable to incorporate decision-theoretic principles that transcend local differences among jurisdictions.

The effects of perceived business uncertainty, external consultants and risk management on organisational outcomes

Purpose: The purpose of this paper is to investigate the relations between perceived business uncertainty (PBU), use of external risk management (RM) consultants, formalisation of RM, magnitude of RM methods and perceived organisational outcomes. Design/methodology/approach: This paper is based on a questionnaire survey of members of the Chartered Institute of Management Accountants in the UK. Using AMOS 17.0, the paper tests the strength of the direct and indirect effects among the variables and explores the fit of the overall path model. Findings: The results indicate significant and positive associations exist between the extent of PBU and the level ofRMformalisation, as well as between the level ofRMformalisation and the magnitude of RMmethods adopted. The use of externalRMconsultants is also found to have a significant and positive impact on the magnitude of RM methods adopted. Finally, both the extent of RM formalisation and the magnitude of RM methods adopted are seen to be significantly associated with overall improvement in organisational outcomes. Research limitations/implications: The study uses perceptual measures of the level of business uncertainty, usage of RM and organisational outcomes. Further, the respondents are members of a management accounting professional body and the views of other managers, such as risk managers, who are also important to the governance process are not incorporated. Originality/value: This study provides empirical evidence on the impact ofRMdesign and usage on improvements in organisational outcomes. It contributes to the RM literature where empirical research is needed in order to be comparable with the traditional management control system literature.

Risk management in organizations:an integrated case study approach

In any organization, risk plays a huge role in the success or failure of any business endeavour. Measuring and managing risk is a difficult and often complicated task and the global financial crisis of the late noughties can be traced to a worldwide deficiency in risk management regimes. One of the problems in understanding how best to manage risk is a lack of detailed examples of real world practice. In this accessible textbook the author sets the world of risk management in the context of the broader corporate governance agenda, as well as explaining the core elements of a risk management system. Material on the differences between risk management and internal auditing is supplemented by a section on the professionalization of risk – a relatively contemporary evolution. Enterprise risk management is also fully covered. With a detailed array of risk management cases – including Tesco, RBS and the UK government – lecturers will find this a uniquely well researched resource, supplemented by materials that enable the cases to be easily integrated into the classroom. Risk managers will be delighted with the case materials made available for the first time with the publication of this book.

Some fairytales about risk management

When I started writing this paper, I thought I would only be writing about the parallel between the mathematical theory of inventory and production – as a familiar model of operations research – and liquidity management. And then during the writing process, predictably enough I must say, the scandals surrounding the Buda-Cash and Quaestor brokerages erupted. Likewise in this period, the debate about foreign currency lending gained fresh impetus; about who made which mistakes when, or whether there was anyone who didn’t make mistakes. The most surprising twist revealed in the Buda-Cash and Quaestor cases – beyond alleged losses running into several hundreds of billions of forints – was that all this could be accumulated in 15 years of selfless effort. And even if this information proves to be comment born of initial over-excitement, it still demands an explanation one way or another. If it’s true, then how can this be? And if it isn’t, then what made it appear as if this is what happened? The questions and contradictions are obvious. But the main questions are these: What do risk managers actually do? What do we pay them for? And how far can we trust them?

Combined exposure to multiple mycotoxins in food: are we ready for risk assessment and risk management?

It is nowadays recognized that the risk of human co-exposure to multiple mycotoxins is real. In the last years, a number of studies have approached the issue of co-exposure and the best way to develop a more precise and realistic assessment. Likewise, the growing concern about the combined effects of mycotoxins and their potential impact on human health has been reflected by the increasing number of toxicological studies on the combined toxicity of these compounds. Nevertheless, risk assessment of these toxins, still follows the conventional paradigm of single exposure and single effects, incorporating only the possibility of additivity but not taking into account the complex dynamics associated to interactions between different mycotoxins or between mycotoxins and other food contaminants. Considering that risk assessment is intimately related to the establishment of regulatory guidelines, once the risk assessment is completed, an effort to reduce or manage the risk should be followed to protect public health. Risk assessment of combined human exposure to multiple mycotoxins thus poses several challenges to scientists, risk assessors and risk managers and opens new avenues for research. This presentation aims to give an overview of the different challenges posed by the likelihood of human co-exposure to mycotoxins and the possibility of interactive effects occurring after absorption, towards knowledge generation to support a more accurate human risk assessment and risk management. For this purpose, a physiologically-based framework that includes knowledge on the bioaccessibility, toxicokinetics and toxicodynamics of multiple toxins is proposed. Regarding exposure assessment, the need of harmonized food consumption data, availability of multianalyte methods for mycotoxin quantification, management of left-censored data and use of probabilistic models will be highlight, in order to develop a more precise and realistic exposure assessment. On the other hand, the application of predictive mathematical models to estimate mycotoxins’ combined effects from in vitro toxicity studies will be also discussed. Results from a recent Portuguese project aimed at exploring the toxic effects of mixtures of mycotoxins in infant foods and their potential health impact will be presented as a case study, illustrating the different aspects of risk assessment highlighted in this presentation. Further studies on hazard and exposure assessment of multiple mycotoxins, using harmonized approaches and methodologies, will be crucial towards an improvement in data quality and contributing to holistic risk assessment and risk management strategies for multiple mycotoxins in foodstuffs.

Portuguese children exposure to multiple mycotoxins through food consumption: toward a holistic approach for multiple mycotoxins risk assessment

Humans can be exposed to multiple chemicals at once from a variety of sources, and human risk assessment of multiple chemicals poses several challenges to scientists, risk assessors and risk managers. Ingestion of food is considered a major route of exposure to many contaminants, namely mycotoxins, especially for vulnerable population groups, as children. A lack of sufficient data regarding mycotoxins children risk assessment, could contribute to an inaccuracy of the estimated risk. Efforts must be undertaken to develop initiatives that promote a broad overview of multiple mycotoxins risk assessment. The present work, developed within the MYCOMIX project, aims to assess the risk associated to the exposure of Portuguese children (< 3 years old) to multiple mycotoxins through consumption of foods primarily marketed for this age group. A holistic approach was developed applying deterministic and probabilistic tools to the calculation of mycotoxin daily intake values, integrating children food consumption (3-days food diary), mycotoxins occurrence (HPLC-UV, HPLC-FD, LC-MS/MS and GC-MS), bioaccessibility (standardized in vitro digestion model) and toxicological data (in vitro evaluation of cytotoxicity, genotoxicity and intestinal impact). A case study concerning Portuguese children exposure to patulin (PAT) and ochratoxin A (OTA), two mycotoxins co-occurring in processed cereal-based foods (PCBF) marketed in Portugal, was developed. Main results showed that there is low concern from a public health point of view relatively to PAT and OTA Portuguese children exposure through consumption of PCBF, considering the estimated daily intakes of these two mycotoxins (worst case scenarios, 22.930 ng/kg bw/day and 0.402 ng/kg bw/day, for PAT and OTA, respectively), their bioaccessibility and toxicology results. However, the present case study only concerns the risk associated with the consumption of PCBF and child diet include several other foods. The present work underlines the need to adopt a holistic approach for multiple mycotoxins risk assessment integrating data from exposure, bioacessibility and toxicity domains in order to contribute to a more accurate risk assessment.

Actionable climate knowledge: From analysis to synthesis

The traditional reductionist approach to science has a tendency to create 'islands of knowledge in a sea of ignorance', with a much stronger focus on analysis of scientific inputs rather than synthesis of socially relevant outcomes. This might be the principal reason why intended end users of climate information generally fail to embrace what the climate science community has to offer. The translation of climate information into real-life action requires 3 essential components: salience (the perceived relevance of the information), credibility (the perceived technical quality of the information) and legitimacy (the perceived objectivity of the process by which the information is shared). We explore each of these components using 3 case studies focused on dryland cropping in Australia, India and Brazil. In regards to 'salience' we discuss the challenge for climate science to be 'policy-relevant', using Australian drought policy as an example. In a village in southern India 'credibility' was gained through engagement between scientists and risk managers with the aim of building social capital, achieved only at high cost to science institutions. Finally, in Brazil we found that 'legitimacy' is a fragile, yet renewable resource that needs to be part of the package for successful climate applications; legitimacy can be easily eroded but is difficult to recover. We conclude that climate risk management requires holistic solutions derived from cross-disciplinary and participatory, user-oriented research. Approaches that combine climate, agroecological and socioeconomic models provide the scientific capabilities for establishment of 'borderless' institutions without disciplinary constraints. Such institutions could provide the necessary support and flexibility to deliver the social benefits of climate science across diverse contexts. Our case studies show that this type of solution is already being applied, and suggest that the climate science community attempt to address existing institutional constraints, which still impede climate risk management.

Estudo exploratório das iniciativas acerca da segurança do paciente em hospitais do Rio de Janeiro

Trata-se de um estudo descritivo e exploratório, que se apoiou na estatística descritiva para abordagem dos resultados produzidos. Tem como objeto as iniciativas para segurança do paciente, implementadas pelos gerentes de risco em hospitais do município do Rio de Janeiro. O estudo teve como objetivo: analisar as iniciativas implementadas pelos gerentes de risco para garantir a segurança do paciente, considerando as iniciativas nacionais e mundiais existentes. Foi desenvolvido em cinco hospitais do Rio de Janeiro, com quatorze gerentes de risco. A técnica utilizada foi a aplicação de um questionário semiestruturado, composto por questões fechadas e abertas sobre as iniciativas para segurança do paciente. Foi verificado que todos realizam atividades voltadas para educação continuada. As menos desenvolvidas são ações de tecno, hemo e farmacovigilância (29%). A maioria informou que se orienta pela Agência Nacional de Vigilância Sanitária, assim como implementa quatro programas para segurança do paciente: a identificação dos pacientes (100%), seguida da assistência limpa é uma assistência mais segura (86%), controle de infecção da corrente sanguínea associada ao cateter (64%) e cirurgia segura, salva vidas (64%). A maior parte dos gerentes de risco desconhece os cinco protocolos operacionais padronizados da Joint Comission on Acreditation of Healthcarecare Organizations e o conteúdo da campanha dos 5 milhões de vidas do Institute for Healthcare Improvement. Os eventos adversos cujo monitoramento é prioritário para os gerentes de risco, são queda do leito (43%) e infecções (36%). A maior parte deles (57%) informa utilizar a análise de causa raiz e análise do modo e efeito da falha como ferramentas de monitoramento de eventos adversos. Conclui-se que grande parte das iniciativas para segurança do paciente são implementadas pelos gerentes de risco, o que vai ao encontro do que é sugerido atualmente, no entanto as iniciativas mais citadas são as iniciativas já divulgadas pelas instituições de referência para segurança do paciente, e que exigem poucos investimentos para serem implementadas, logo é essencial mais ações de capacitação dos gerentes de risco e de desenvolvimento de uma cultura de segurança no ambiente hospitalar.

Les composantes du risque : une entrée par les acteurs et le conflit lors de la mise en place des solutions : le cas de Los Chorros, Guatemala

Ce travail présente une étude de cas post-catastrophe à San Cristobal, Guatemala, où un important glissement de terrain du nom «Los Chorros» (8-10 millions de m3 de roche) affecte depuis 2009 diverses communautés et une des routes principales du pays. Les gestionnaires des risques, sur la base de leur propre évaluation, ont décidé de répondre d'une manière qui ne correspond pas aux intérêts de la population affectée. Les communautés locales ont évalué le risque de catastrophe et ont établi une autre solution suivant une conception du risque différente. Les conflits sociaux et la concurrence entre les différents acteurs du territoire, pour la définition des priorités et des solutions, révèlent les aspects sous-jacents de la société, utiles pour identifier et comprendre ce qui constitue le risque de catastrophe dans un contexte donné. Ce conflit montre que le risque de catastrophe n'est pas univoque mais un concept complexe, constitué par un grand nombre de composants. En termes de gouvernance, il met également en évidence la confrontation des savoirs et la tension qui peut exister entre les différentes approches du risque. Depuis une approche où le risque de catastrophe est considéré comme une construction sociale (les vulnérabilités étant historiquement générées par des processus sociaux, politiques, économiques et culturels), ce travail évalue d'autres modes d'interprétation, de traitement et d'intervention qui peuvent aider à améliorer les méthodes d'évaluation et de gestion des risques. Enfin, la proposition de gestion qui découle de l'exemple guatémaltèque invite à une autre manière de concevoir la gestion des risques en intégrant les différentes conceptions du risque et en visant une coordination stratégique entre les acteurs des politiques publiques, les échelles d'intervention, les experts en charge des différents aléas et la société civile, afin d'obtenir une solution acceptable pour tous les acteurs impliqués dans un territoire. -- This work analyses a post-disaster case study from San Cristobal, Guatemala where a large landslide named "Los Chorros (8 millions cubic meters of rock) affects several communities and one of the country's main west-east access highways. Risk managers, starting from their own assessment, decided to respond in a way that does not correspond to the interests of the afected population. Local communities assessed the risk disaster situation and establised another solution from a different conception of risk. These social conflict and competition for priorities and solutions for risk management reveal that disaster risk is not unequivocal but a complex and holistic concept, constituted by a large set of components. From a social constructivism approach, where disaster risk is considered as the results of social, political, economic and historic process, this thesis evaluates other modes of interpreting, shaping and managing risk that can help improve methods of risk assessment and management. Studying the logic of action of actors, who mobilize to establish a solution, enables to identify as to what constitutes a disaster. For this reason, the study focus, in particular, on the analysis of practices (practical science) implemented by all actors in San Cristobal Altaverapaz. Finally, it puts into perspective the risk management in terms of an integrative approach for policy experts that find compromise between different conceptions of risk in order to obtain a solution acceptable to all those involved.

Avaliação de Riscos : Estimação Qualitativa da Probabilidade e da Gravidade em Contexto de Risco Elevado

O processo de gestão de risco consiste, no estudo estruturado de todos os aspetos inerentes ao trabalho e é composto pela análise de risco, avaliação de risco e controlo de risco. Na análise de risco, é efetuada a identificação de todos os perigos presentes e a estimação da probabilidade e da gravidade, de acordo com o método de avaliação de risco escolhido. Este estudo centra-se na primeira etapa do processo de avaliação de risco, mais especificamente na análise de risco e nos marcadores de informação necessários para se efetuar a estimação de risco na industria extrativa a céu aberto (atividade de risco elevado). Considerando que o nível de risco obtido, depende fundamentalmente da estimação da probabilidade e da gravidade, ajustada a cada situação de risco, procurou-se identificar os marcadores e compreender a sua influência nos resultados da avaliação de risco (magnitude). O plano de trabalhos de investigação foi sustentado por uma metodologia qualitativa de recolha, registo e análise dos dados. Neste estudo, a recolha de informação foi feita com recurso às seguintes técnicas de investigação: - Observação estruturada e planeada do desmonte da rocha com recurso a explosivos; - Entrevista individual de formadores e gestores de risco (amostragem de casos típicos); Na análise e discussão qualitativa dos dados das entrevistas recorreu-se às seguintes técnicas: - Triangulação de analistas e tratamento de dados cognitiva (técnicas complementares); - Aposição dos marcadores de informação, versus, três métodos de avaliação de risco validados. Os resultados obtidos apontam no sentido das hipóteses de investigação formuladas, ou seja, o tipo de risco influi da seleção da informação e, existem diferenças significativas no nível de risco obtido, quando na estimação da probabilidade e da gravidade são utilizados marcadores de informação distintos.
