    What is Health Impact Assessment? What is Health Impact Assessment? Presentation Transcript

    • What isHealth Impact Assessment? University of Newcastle August 2012 Ben Harris-Roxas www.harrisroxashealth.com @ben_hr on Twitter
    • Section 1Who am I?
    • I’ve been working on HA since 2003 Mainly through supporting and conducting HIAs I consult and also teach atUNSW, UWS and Macquarie University
    • Trained more than 550 people in HIAActive in international HIA community IAIA Health Section Co-Chair
    • Section 2What is health and what creates it?
    • • Historical understandings
    • Miasma model of disease
    • Environmental causes
    • The view that health ismerely the absence of illness and disease
    • controlling theenvironmental causes of disease =dealing with most public health concerns or does it?
    • many of the early gains in public health were linked to improving the environmental factors that cause disease the environmental determinants of health You’ll learn more about these during the course
    • sanitationvoted the most important medicaladvance since 1840.
    • air, water andsoil quality and toxicity
    • disease vector control
    • waste managementImage: ŧĒđĠūŸ®
    • housing quality andovercrowdin g
    • But the global burdenof disease has shifted
    • Source: WHO Global Burden of Disease 2002
    • Much of this disease still has environmental causes Many of the new causes of disease seemed to be different in nature to traditional environmental health concernsUnder-considered factors that powerfully influence healthand health related behaviours

    • Section 3What is HIA?
    • A combination of procedures, methods and tools by which a policy, program or project may be assessed for its potential and often unanticipated effects on the health of the population and the distribution of these impacts within the population. Gothenburg Consensus PaperEuropean Centre for Health Policy (1999) Gothenburg Consensus Paper on Health ImpactAssessment: main concepts and suggested approach, WHO Europe: Brussels (adapted byMahoney & Morgan).
    • HIA is a developing approach that can help to identify and consider the potential - or actual - health impacts of a proposal on a population. Its primary output is a set of evidence-based recommendations geared to informing the decision making process. Taylor & QuigleyTaylor L, Quigley R. (2002) Health Impact Assessment: A review of reviews. London: NationalHealth Service, Health Development Agency.
    • Key Aspects of HIA• A prospective activity• Uses a combination of methods• Looks at intended and unintended impacts• Looks at the distribution of impacts• Results in evidence- informed recommendations
    • When is an HIA done?
    • Explicit Focus on the Distribution of Impacts1. Age2.Gender3.Socioeconomic status4.Location5.Ethnicity and culture6.Existing levels of health anddisability7..
    • Thinking about the distribution of impacts: Avoidability and fairness Lead exercise
    • Section 4Steps of HIA
    • The Steps of HIA• Screening• Scoping• Identification• Assessment• Decision-making and recommendations• Evaluation and follow-up•.
    • Assessment Recommendations If you These will be If you make These will beimplement the the impacts these changes the gains proposal
    • Where does health risk assessment (HRA) fit in?
    • HRA is a structured framework for assessing risks associated with environmental hazards (prospectively and retrospectively)
    • “The process of estimating the potentialimpact of a chemical, biological, physical orsocial agent on a specified human populationunder a specific set of conditions and for acertain time frame’ enHealth HRA Guidelines
    • Scoping ActivityMaster Plan for Cheonggyecheon, Seoul
    • First, get in your time machine –back to 2003
    • • Project timeline 2003 - 2005• US$900 million project
    • After Construction Now (2003)
    • • Proponent receptive to HIA, but must be completed in 5 months (mustn’t hold up construction!)• Proponent is Seoul City Government, who are reasonably convinced the proposal is a good idea• Proponent has asked that the HIA’s focus should be on improving proposal and tweaking, not suggesting new major initiatives or “vetoing” the initiative

    • Section 6Where did HIA come from?
    • Environmental health Social view of health EquityEach bring with them their own disciplinary beliefs, values, support base and baggage

    • Section 7What forms does it take?
    • There are currently four models of HIA being used internationally (to varying extents)
    • Mandated HIA generally occurs in the context of an EIA, IIA, or ESHIA and is done to meet a regulatory or statutory requirement
    • Example: Basslink Integrated IA
    • HIA for decision support is generally done voluntarily with the goal of improving decision-making and implementation
    • Example: Lower HunterRegional Strategy HIA
    • HIA for advocacy is usually undertaken by organisations who are neither the proponent or the decision-maker
    • Example: HIA of the NationalEmergency Response in the Northern Territory
    • Community empowerment HIAs are usually undertaken by communitieswhose health is likely to be affected by a proposal
    • Example: Goodooga Equity Focused HIA
    • Mandated Decision Support• If HIA is mandated the • If decision support forms process will have to be are pursued the process is more prescribed, more chaotic• standards of practice will (more of a process than a need to be described, methodology)• tighter definitions of • Less clarity about who will evidence that can be do it and where it might sit challenged in court will need within organisations to be determined,• accreditation of practitioners• Triggers will need to be clear• Clarification of the roles & responsibilities of proponents of government policy
    • Advocacy Community Empowerment• Seeks to reframe or • Difficulty: no control over challenge issue/proposal process or decisions• Requires a close link to • Community unlikely to be evidence to be credible bound by disciplinary• Hard to involve proponents traditions/evidence and decision-makers • Often linked to social• Who would do it routinely learning, i.e. changing is unclear understandings, enabling• Often seeks to bring in dialogue other evidence/only • Is a democratic and political selective evidence process, rather than a• May have an agenda – technocratic or rational need to be explicit about process this • May look quite different to other HIAs
    • This diversity is widespread and the challenges efforts to make HIA embedded in the policy development and decision making processExample: Lack of consensus about HIA from the National Public Health Partnership But also enables responsiveness to emerging issues

    • Types of Health ImpactsHarris-Roxas B, Harris P. Learning by Doing: The value of case studies of healthimpact assessment. NSW Public Health Bulletin, 2007:161-163.
    • Increasingly also on:• Climate change (adaptation)• Transition-to-town issues (food miles, sustainability, etc)• Energy• Social programs and education•.
