(HIA) is a powerful tool for evaluating how policies and projects affect public health. It considers social, economic, and environmental factors to maximize positive outcomes and minimize negative impacts, especially for vulnerable groups.
HIAs follow a structured process of screening, scoping, assessment, and recommendations. They involve diverse stakeholders, use various data collection methods, and aim to influence decision-making to promote across different sectors and communities.
HIA Process
Overview of Health Impact Assessment (HIA)
Systematic process evaluates potential health effects of a proposed policy, plan, program, or project before implementation
Considers social, economic, and environmental determinants of health
Aims to maximize positive health outcomes and minimize negative impacts, particularly for vulnerable populations
Conducted by a multidisciplinary team of experts (public health professionals, urban planners, transportation specialists, environmental scientists)
Follows a structured framework consisting of screening, scoping, assessment, and recommendations
Screening and Scoping Stages
Screening determines whether an HIA is needed and feasible based on potential health impacts, available resources, and stakeholder interest
Involves reviewing existing data, consulting with stakeholders, and assessing the project's timeline and decision-making process
Scoping establishes the HIA's objectives, study area, affected populations, health determinants, and methods
Identifies key health issues, research questions, data sources, and stakeholders to engage (community members, policymakers, industry representatives)
Develops a work plan outlining the HIA's timeline, budget, and responsibilities
Assessment and Recommendations Phases
Assessment phase collects and analyzes data to characterize the baseline health status of the affected population and predict potential health impacts
Uses quantitative methods (risk assessment, epidemiological studies, health impact modeling) and qualitative approaches (community surveys, focus groups, expert interviews)
Considers positive and negative health effects, their magnitude, likelihood, and distribution across different population subgroups
Recommendations suggest actions to enhance positive health outcomes and mitigate negative impacts based on the assessment findings
Prioritizes recommendations based on their feasibility, effectiveness, and alignment with stakeholder priorities
Examples include modifying project design (adding green spaces to promote physical activity), implementing mitigation measures (installing air filters to reduce pollution exposure), or supporting health-promoting policies (investing in affordable housing)
HIA Outcomes and Follow-up
Reporting and Dissemination
Reporting communicates the HIA's findings, recommendations, and decision-making process to stakeholders and the public
Includes a written report, executive summary, and presentations tailored to different audiences (community members, policymakers, media)
Emphasizes key messages, actionable recommendations, and transparent documentation of methods and limitations
Dissemination strategies aim to raise awareness, build support, and facilitate the uptake of HIA recommendations (public meetings, media outreach, online platforms)
Monitoring and Evaluation
Monitoring tracks the implementation of HIA recommendations and assesses their impact on health determinants and outcomes over time
Uses indicators and data sources identified during the scoping and assessment phases (health surveys, environmental monitoring, community feedback)
Evaluation assesses the HIA's process, impact, and effectiveness in influencing decision-making and promoting health equity
Involves collecting data from stakeholders, reviewing documents, and conducting interviews or surveys
Identifies strengths, weaknesses, and lessons learned to improve future HIA practice and inform ongoing decision-making processes
Evidence-Based Decision Making
HIAs provide decision-makers with evidence-based recommendations to promote health and equity in policies, plans, and projects
Supports the integration of health considerations into non-health sectors (transportation, housing, education) and promotes
Enhances transparency and accountability in decision-making by documenting the potential health impacts and trade-offs of different options
Strengthens the capacity of communities and stakeholders to participate in decision-making processes and advocate for their health needs
Contributes to the growing body of evidence on the effectiveness of HIAs in promoting health and equity in diverse contexts (urban planning, natural resource extraction, climate change adaptation)
HIA Principles
Addressing Determinants of Health
HIAs recognize that health is influenced by a wide range of social, economic, and environmental factors beyond individual behaviors and healthcare access
Considers the distribution of health determinants across different population subgroups and their cumulative impacts over time
Examples of health determinants include income, education, housing, transportation, social support, environmental quality, and access to health services
HIAs assess how proposed policies or projects may influence these determinants and their associated health outcomes (cardiovascular disease, respiratory illness, mental health)
Aims to promote health equity by identifying and addressing the root causes of health disparities and ensuring that all population groups have the opportunity to attain their full health potential
Stakeholder Engagement and Participation
HIAs emphasize the importance of engaging diverse stakeholders throughout the assessment process to ensure that their perspectives, knowledge, and values are considered
Stakeholders may include community members, policymakers, public health professionals, industry representatives, and academic experts
Engagement strategies aim to build trust, facilitate dialogue, and promote shared decision-making (community forums, advisory committees, participatory mapping)
Seeks to empower communities, particularly those most affected by the proposed policy or project, to participate in the HIA process and advocate for their health needs
Recognizes that stakeholders may have different interests, power dynamics, and capacities to participate, and aims to create an inclusive and equitable engagement process
Examples of in HIAs include involving community members in data collection and analysis, seeking input on draft recommendations, and disseminating findings through community-based organizations and networks
Key Terms to Review (19)
Community engagement: Community engagement refers to the collaborative process of working with individuals and groups in a community to address issues that matter to them, fostering a sense of ownership and participation. This involves establishing relationships, promoting dialogue, and ensuring that the voices of community members are heard in decision-making processes.
Cross-sectoral collaboration: Cross-sectoral collaboration refers to the process of different sectors—such as health, education, environment, and urban planning—working together to address complex social issues. This approach recognizes that many challenges, like public health, cannot be solved by one sector alone, and therefore requires input and cooperation from multiple stakeholders to create comprehensive solutions that improve overall well-being.
Determinants of health model: The determinants of health model refers to a framework that identifies the various factors influencing health outcomes within populations. These determinants encompass a range of factors, including social, economic, environmental, and genetic influences, which all interact to shape individual and community health. By understanding these interrelated factors, public health professionals can develop targeted interventions to improve health outcomes and address health disparities.
Environmental Impact: Environmental impact refers to the effect that a project, action, or policy has on the surrounding environment, including aspects such as ecosystems, wildlife, air quality, and water resources. Understanding these impacts is crucial for making informed decisions that promote sustainability and public health while minimizing negative consequences on natural resources and community well-being.
