Lessons Learned in Initiating and Conducting Risk Assessments within a Risk Analysis Framework: A FDA/CFSAN Approach Robert Buchanan DHHS Food and Drug Administration Center for Food Safety and Applied Nutrition
Perspective Risk Assessor vs. Risk Manager Risk Manager vs. Risk Assessor
The Paradox • Codex Alimentarius “Principles and Guidelines for the Conduct of Microbial Risk Assessments” • Principle #2: There should be a functional separation between risk assessment and risk management • Important principle that doesn’t work if you achieve it
Setting the Stage • Experience: conducted two large quantitative microbial risk assessments • Vibrio parahaemolyticus • Listeria monocytogenes • Learning: address the “bumps” encountered • to discuss lessons learned • to develop a risk analysis framework for future major risk assessments
The Bumps • Resource intensive • Setting time frames and establishing deadlines • Establishing why risk assessment is being done • Establishing expectations • What a risk assessment can do? • Establishing boundaries • Who is in charge? • Who gets to decide? • Who settles conflicts?
The Bumps • Communicating with risk managers (Why can’t risk assessors speak English?) • Modeling • Explaining uncertainty vs. variability • Lack of understanding of risk assessment techniques (Why are risk managers so dense?) • Getting risk managers to pay attention early
The Bumps • Presenting the results • Interpretation • Transparency • Plain language (Who rights the report?) • Dealing with unexpected results • Review of risk assessments • Impact on risk management programs • Protecting the risk assessors against outside pressure
Risk Analysis Working Group • Senior managers • Risk managers • Risk assessors • Scientists • “Modelers” • Project leaders • Risk Communicators • Facilitator
Risk Analysis Working Group • Overall Goal: To improve the quality and consistency of “major” risk assessments conducted by the Center for Food Safety and Applied Nutrition
What Are ‘Major’ Risk Assessments? • Non-routine, complex, and/or quantitative • Involve multiple program offices and/or cross-cutting in nature • Require a commitment of significant resources to complete
Risk Analysis Working Group Specific Tasks: 1) Identify boundaries and responsibilities of key participants in the risk analysis process 2) Develop a process for identifying and selecting risk assessments conducted by CFSAN 3) Establish procedures for the conduct of risk assessment within a risk analysis framework
Risk Management Risk Communication Risk Assessment Risk Analysis – The Theory • Traditional definition: risk analysis is composed of : • Risk Management • Risk Assessment • Risk Communication
Risk Mgmt CFSAN Mgmt Risk Communi- cation FDA GC Risk Assess- ment FDA Mgnt Research Risk Analysis – The Reality • In CFSAN risk analysis is a “stew” of : • Center Management • Risk Management • Risk Assessment • Risk Communication • Research • Etc
Procedures to Initiate and Conduct Risk Assessments • INITIATE: A decision-based approach to identify and select all ‘major’ risk assessments • Four phase process: concept generation, problem identification, data feasibility evaluation, disposition • CONDUCT: A systematic and iterative approach to conducting risk assessments • Four step process: Plan, Perform, Review, Publish
Selection of Major Risk Assessments • Select major risk assessments on basis of • Center’s risk management needs • Center’s resources • Data feasibility
Personal Observation • If science is complex, there is no consensus among stakeholders, and there are multiples ways of managing the risk – consider a quantitative risk assessment • If science is straight forward, there is general consensus among stakeholders, and there is only one risk management option – do not conduct a quantitative risk assessment
Where do risk assessment ideas come from? • Stakeholders (public) • Follow up to completed risk assessment • Regulatory staff • Management • Researchers • Other agencies
A Four Phase Selection Process Phase 1:Concept Generation Phase 2:Problem Formulation Phase 3:Feasibility Determination Phase 4:Disposition
Selection Process • Identify and maintain list of potential RM questions for which a RA would assist with policy decisions • Identify hazards/commodities • State the RM question(s) • State the RA question(s) Concept Generation Problem Formulation Feasibility Determination Disposition (selection)
Selection Process Management reviews list and approves specific RAs for further evaluation (feasibility determination) Concept Generation Problem Formulation Feasibility Determination Disposition (selection)
Selection Process • Review literature to determine availability of data needed to conduct RA to answer RM questions • Recommend action: • More research needed • Modify RM question • Qualitative RA vs. Quantitative RA Concept Generation Problem Formulation Feasibility Determination Disposition (selection)
Selection Process Using the results of the feasibility determination as an aid, management selects RAs to be conducted based on technical merit, resource availability, and other factors and get commitment of resources Concept Generation Problem Formulation Feasibility Determination Disposition (selection)
Conducting the Risk Assessment A four step process: • Step 1: Plan • Step 2: Perform • Step 3: Review • Step 4: Publish
Conducting the Risk Assessment • Step 1: Planning • Define scope • Identify resource needs • Assign teams • Develop timelines
Conducting the Risk Assessment • Step 2: Perform • Answer risk management questions
An Iterative Process Receive Charge from Risk Managers Receive Assumptions from RM Refine Assumptions for modeling Assemble data/model inputs Verify data/model inputs Develop model Audit model New data Run model/iterations Conduct sensitivity analysis Review results Draft Report
Conducting the Risk Assessment • Step 3: • Review – ongoing process • Advisory Committees • Peer Review • SGE Panels • Public Comment • Approve • Clear
Technical and Scientific Reviews of the Draft Risk Assessment Documents
Conducting the Risk Assessment • Step 4: Publish • Develop “roll out” strategy • Public release of documents • Handling comments • Public comment
Organization of Risk Analysis • Risk analysis should be conducted by teams: • Risk Management Team • Risk Assessment Team • Risk Communication Team • Meet regularly to discussion process and surface issues
Organization of Risk Analysis • Established three unique positions to help with consistency, coordination, and making decisions • Science Advisor for Risk Analysis • Risk Analysis Coordinator • Risk Assessment Project Manager
Summary of Recommendations Implemented • Decision-based approach to identify and select all ‘major’ risk assessments • Procedure for the conduct of risk assessment within risk analysis framework • Established new organizational structure
Summary of Recommendations Implemented • Criteria to evaluate data quality • Procedures for the approval and release of risk assessments • Formal peer review process • Enhance capabilities to conduct risk assessments and interaction between chemical and microbiological risk assessments
Report Available • “Initiation and Conduct of All ‘Major’ Risk Assessments within a Risk Analysis Framework” • Available on FDA website: • http//:www.cfsan.fda.gov/~dms/rafw-toc.html
New Twists • OMB Guidelines on Data Quality • Court decisions of status risk assessment when used as part of a regulatory activity • Security issues when risk assessment used for food security activities
