1. A Comparison of 42 Local, National, and International HIA Guidelines Andrew L. Dannenberg, MD, MPH Katherine Hebert, MCRP Arthur M. Wendel, MD, MPH Sarah H. Kennedy, MPH Healthy Community Design Initiative Centers for Disease Control and Prevention, USA International Health Impact Assessment Conference Granada, Spain, April 2011

2. Background HIAs have been conducted for 20+ years No one standard procedure established Many guidelines developed over past decade This study reviews existing guidelines Builds on prior work by Mindel et al

3. Methods Search for existing HIA guidelines –Authors’ knowledge of existing guidelines –HIA Gateway, HIA Connect, IMPACT, WHO, and others –2008 article by Mindell et al* –Networking with HIA colleagues –Literature search *Mindell JS et al. A review of health impact assessment frameworks. Public Health. 2008; 122:1177-1187

4. Methods (continued) Inclusion: –Intent of document to guide HIA conduct Exclusion: –Old guide for which newer version available –Sector-specific (eg, only for mining or for greenspace) –Step-specific (eg, describes only screening step) Extract key information from documents

5. Number of HIA Guides by Year of Publication (N=40*) *Date not available for two guides Year

Feature Percent Including Feature (N) Encourages community engagement98% (41) Considers equity/ inequalities across population95% (40) Includes a list/ diagram of health determinants88% (37) Includes a steering committee/ group88% (37) Includes examples, case studies, resources, etc.86% (36) Multiple levels of HIA (rapid, intermediate, etc.)81% (34) Applicable to policy, project, and program76% (32) Recommends a community profile74% (31) Recommends prospective HIA only74% (31) Voluntary approach/ not tied to policy74% (31) Includes list of principles64% (27) Discusses integration with other impact assessments62% (26) Specific Features of 42 HIA Guidelines

10. Step Percent Including Step (N) Screening100% (42) Scoping100% (42) Assessing Risks and Benefits100% (42) Recommendations/ Implementation Plan 74% (31) Reporting74% (31) Evaluation/ Monitoring90% (38) Steps Described in 42 HIA Guidelines

11. Describes selection process for projects and policies that should undergo an HIA (95%) Intended to be a quick and efficient process (69%) Includes a checklist of questions to be transparent in proposal selection (64%) Indicates availability of specific screening step tools Screening

12. Describes process for establishing a framework or work plan and selecting impacts to study (98%) Identifies which level or type of HIA to conduct (69%) Sets geographic and population boundaries (90%) Identifies stakeholders and/or forms a steering committee (93%) Scoping

13. Describes step as quantitative and qualitative methods to organize information on current population status and possible health impacts (100%) Prioritizes potential impacts based on strength of evidence, likelihood and scale of impact, contribution to reducing inequalities, and relevance (74%) Includes a tool for prioritizing impacts/ organizing information (60%) Assessment

14. Describes step as formulating ways to improve a proposal to maximize positive health impacts and minimize negative impacts (100%) States that recommendations should be practicable, achievable, acceptable to stakeholders, and supported by evidence (76%) May include a detailed Health Action Plan Recommendations

15. Step described as providing stakeholders and decision-makers with information about the process, findings, and recommendations of the HIA (95%) May provide guidance on what to include in a report and on matching type of report to type of audience Reporting

16. Step described as reflecting on the HIA process, impact, and health outcomes (86%) Considered an important step to building the HIA field (71%) Recommends talking with decision-makers as part of evaluation Monitoring/Evaluation

17. Study Limitations Some guidelines may have been missed in search Predetermined terminology in search and in analysis may have reduced diversity of findings Components of guidelines may be interpreted differently by different users

18. Conclusions Guidelines for HIAs are similar in many areas of the world although some variations exist How closely the practice of HIA follows the published guidelines is unknown Further work is needed to determine if one set of common guidelines could be written for use in numerous countries and regions
