General RA/RM framework Systematic analysis according to societal needs
Societal setting for RA/RM • Risk assessment is collection, synthesis and interpretation of scientific information and value judgments for use of the society • Risk management is use and implementation of that information
SOTA in EHA BEPRARIBEAN research project Manuscript: “State-of-the-art in benefit-risk analysis: Environmental health” to be published soon-ish One out of a set of six “SOTA in BRA” papers Others domains considered are: Food and nutrition,Food microbiology, Economics and marketing-finance, Medicine, Consumer perception Available in Heande (link on the course web-page) Also a “Beyond the SOTA in food and nutrition BRA” manuscript is in preparation Combines the lessons learned in above mentioned studies
SOTA in EHA What is the SOTA in EHA? Underlying: what could food and nutrition BRA learn from the SOTA in EHA?
SOTA in EHA 8 approaches to environmental health assessment: Red Book risk assessment Understanding risk IRGC risk governance framework Chemical risk assessment: REACH Environmental impact assessment: YVA Health impact assessment (HIA) Integrated environmental health impact assessment (IEHIA) Open assessment Why not: Life-cycle assessment? Nuclear safety assessment? Silver Book?
SOTA in EHA Analysis framework: Purpose: What need(s) does an assessment address? Problem owner: Who has the intent or responsibility to conduct the assessment? Question: What are the questions addressed in the assessment? Which issues are considered? Answer: What kind of information is produced to answer the questions? Process: What is characteristic to the assessment process? Use: What are the results used for? Who are the users? Interaction: What is the primary model of interaction between assessment and using its products? Performance: What is the basis for evaluating the goodness of the assessment and its outcomes? Establishment: Is the approach well recognized? Is it influential? Is it broadly applied?
SOTA in EHA Interaction: Trickle-down: Assessor's responsibility ends at publication of results. Good results are assumed to be taken up by users without additional efforts. Transfer and translate: One-way transfer and adaptation of results to meet assumed needs and capabilities of assumed users. Participation: Individual or small-group level engagement on specific topics or issues. Participants have some power to define assessment problems. Integration: Organization-level engagement. Shared agendas, aims and problem definition among assessors and users. Negotiation: Strong engagement on different levels, interaction an ongoing process. Assessment information as one of the inputs to guide action. Learning: Strong engagement on different levels, interaction an ongoing process. Assessors and users share learning experiences and implement them in their respective contexts. Learning in itself a valued goal. A continuum of increasing engagement and power sharing

Main findings EHA is a very complex field Environment? Health? No single SOTA approach exists Approaches often either academic or regulatory Assessment centered vs. management centered? Traditional and novel approaches Regulatory and traditional tend to be more established
EHA NOTE: this is an influence diagram (not a process diagram) Adapted from Briggs: A framework for integrated environmental health impact assessment of systemic risks. Environmental Health 2008, 7:61.
Main findings Purpose: All state to aim to support societal decision making Question, answer, process: Quite different operationalization of the (stated) aims Question, answer: Huge differences in scopes Process, interaction: Mostly expert activity in institutional settings Performance: Societal outcomes hardly ever considered
Main findings The key issues in benefit-risk analysis in environmental health are not so much related to the technical details of performing the analysis, but rather: i) the level of integration (cf. Scope) ii) the perspective to consider the relationship between assessment and use of its outcomes in different assessment approaches “Assessment push” or “needs pull” The means of aggregation are basically the same as in other fields e.g. DALY, QALY, willingness-to-pay (WTP)
Main findings In EHA there are tendencies towards: a) increased engagement between assessors, decision makers, and stakeholders b) more pragmatic problem-oriented framing of assessments c) integration of multiple benefits and risks from multiple domains d) inclusion of values, alongside scientific facts, in explicit consideration in assessment Indicative of the incapability of the common contemporary approaches to address the complexity of EHA? Does not necessarily show much (yet) in practice
Implications to RM? RM more or less included in the approaches E.g. YVA & REACH are actually RM approaches that include assessment Purpose, use, interaction, … all (somewhat) acknowledge RM and the broader societal context
Other perspectives to RM For example: The EHRM framework by The Presidential/Congressional Commission on Risk Assessment and Risk Management Risk-based decision making framework, i.e. The NRC Silver Book approach
EHRM framework The Presidential / Congressional commission on Risk Assessment and Risk Management: Final Report Volume 1, 1997.

How does RM look like according to the frameworks? Mostly institutional Professional/expert-based Often considered as single-actor activity Primarily unidirectional (knowledge push) Rational Quite straightforward Implementation of decisions is not the (big) problem Is this a realistic view?
How does RM look like according to the frameworks? A caricature of traditional risk research Risk assessment: Scientific experts deal with scientific facts Risk management: Professional decision makers make decisions according to the scientific facts Risk communication: Commuication experts explain the decisions and the facts to the ignorant (stakeholders, NGO’s, public, …) Risk perception: Scientific experts analyze why do not the ignorant understand the facts Also in DA there are two branches What decision should be taken? How are decisions actually made? Are distinctions necessary? Does it correspond with reality and practical needs? Do these things need to be kept separate?
Reality of EHRM? Environment and health relevant to everyone Multiple relevant decision situations Multiple relevant questions Multiple relevant actors Multiple relevant roles Multiple relevant sources of knowledge Experts and professional (societal) decision makers of course, but also: DMs in business and industry NGO’s Common citizens
Reality of EHRM? Reality is much more complex than the (common) RM frameworks recognize/describe Simplicity -> explicitness -> good guidance? Should it not be possible to expand the scope of systematic analysis/practice? The emerging approaches in EHA more or less aim to merge assessment and management into an intertwined social knowledge process Assumes a too rational and straightforward practice of assessment, management, and implementation?
Discussion Intro to RM exercise RM in the swine flu case
RM exercise Individual work Max. score 10 points Course total max. 45 points Reports are written in Opasnet Pages were created for each student in the introduction to Opasnet lecture 4.3. Presentations of reports in final seminar 11.-12.4. If needed, improvements can be made up to the final evaluation in the end of April
RM exercise Task description: Consider yourself in the role of the Ministry of Social and Health affairs Development of capacity to manage major public health risks Evaluate all four DA study plans from the use/r point of view: What value would each planned analysis bring you? Make use of the properties of good assessment framework: Relevance (is content relevant in relation to purpose?) Pertinence (is purpose relevant in relation to use?) Usability (does your understanding increase?) Availability (is information accessible and/or timely?) Acceptability (Would results/conclusions be acceptable to you? Why or why not?) Give an overall statement: would/could the analysis influence your practices (in the given imaginary role)? Also explain how
RM exercise Task description (continued): Take (one) another perspective and repeat the evaluation of the DA study plans E.g. common citizen, medical superintendent in a hospital, health researcher, journalist, nurse in public health care, principal of an elementary school, … Focus on the differences in comparison to the above evaluation Write an (freely formatted) evaluation report and present the main findings in the final seminar More detailed instructions (will be) available on the exercise web-page in Opasnet
Reasons for changing exercise part 2 More explicit task (?) Clearer linkage between DA & RM Students can better make use of their earlier efforts in working on the DA study plans Might help in improving the study plans too! Emphasizes different perspectives to DA & RM First half of the course mostly expert/assessor point of view Activates collaboration and cross-fertilization between students and groups Collective learning!
Discussion: RM in the swine flu case RM in the swine flu case What risks exist(ed) in the swine flu case? What risks are/were addressed? How? Who are/were in the roles of managing the risks? Who else are/were involved? What roles do/did they take? On what basis do/did different actors take action to manage (in a way or another) the risks?
Concepts Some basic concepts: Performance = goodness! Assessment, Management Model Process (making/using), Product Output, Outcome Assessor, Decision/Policy maker, Stakeholder Participant, User
