Health Impact Assessment

Health impact assessment (HIA) is a prospective approach to anticipate future direct and indirect health effects of projects, programmes or policies implemented in sectors other than health. Through a combination of procedures, tools and methods, systematic HIA provides an evidence-base for decision-making on how to manage those effects adequately and supports at the same time the health-in-all sectors approach as promoted by the SDG agenda. The holistic HIA approach takes into account direct effects of projects, programmes or policies on human health but equally considers underlying social and environmental determinants of health, which are expected to alter through implementation and indirectly influence population health.

At Swiss TPH, our HIA expertise and activities cover the full spectrum from HIA service provision, HIA research and HIA teaching and training. We have long-standing expertise in the assessment, monitoring and evaluation of health impacts associated with drivers of global change, namely population growth, migration, urbanization, natural resource extraction and climate change, with a focus on tropical and development regions.

We work in an inter- and transdisciplinary team at the interface of service provision, research and capacity building. Our team understands and applies the best international and sector-specific standards and works in accordance with principles put forward in the Sustainable Development Goals (SDGs) agenda. We place a particular focus on tropical regions and low- and middle-income countries where we have a broad network with public, academic and private actors.

Examples of HIA services offered:

  • Rapid and comprehensive HIA of projects, programmes and policies that cover the full range of potential environmental, socio-cultural and economic factors of concern
  • Health economic analyses and cost-benefit analyses as integral part of HIA
  • Health risk assessment applying a range of quantitative, semi-quantitative and qualitative methods
  • Health facility assessments
  • Epidemiological surveys for defining baseline conditions and facilitating impact monitoring of project, policy or programmes, with methods ranging from participatory data collection to clinical studies and environmental sampling
  • Environmental exposure assessments
  • Social vulnerability assessment and social resilience assessments using qualitative and mixed-methods approaches
  • Geospatial analysis and dispersion modelling
  • One Health population-based assessments that span across different health sectors (human, animal, plants/environment)
  • Life course perspective in health and illness in planning, implementation, monitoring and evaluation
  • Community health management planning and implementation
  • Gender equity in planning, implementation, monitoring and evaluation
  • Independent, external evaluations, reviews and audits of HIAs

We believe that HIA research is central in advancing HIA practice. Our research has significantly contributed to methodological approaches and provided valuable case study examples of HIA practice in low- and middle-income countries. We are committed to regularly publish methodological approaches and HIA outcomes in scientific journals and reports.

At the national level, Swiss TPH offers courses on HIA at the graduate and post-graduate level at the Swiss Federal Institute of Technology in Zurich (ETHZ) and other universities in Switzerland. At the international level, Swiss TPH is playing a leading role in ongoing HIA capacity building efforts in Brazil (in close collaboration with the Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro) and Vietnam (in close collaboration with the Hanoi University of Public Health). Upon request, Swiss TPH offers tailor-made HIA training courses for diverse audiences, including government agencies, development agencies, industry associations, academic institutions or funding agencies in English, German, French and Portuguese.

Public Health Strategies for Artisanal and Small-Scale Gold Mining Activities

The artisanal and small-scale gold mining (ASGM) sector produces about 12-15% of the world's gold and occupies an estimated 10-15 million miners globally. This project is piloting the use of a framework and related tools developed by the World Health Organization (WHO) and is conducting a rapid health situation assessment in order to support the development of public health strategies on ASGM in Ghana, Mozambique and Nigeria.

Climate Change Adaption to Improve Livelihoods in Peru

CLIMANDES-2 aims at developing user-tailored climate services for the agricultural sector in the Andean region of Peru with respect to user needs and requirements. In order to provide best possible climate information for decision-making, this project pursues an integrative approach combining the development of user-specific seasonal predictions, traditional knowledge, capacity building within the thematic fields of the project and the generation of. Hence, science-based climate information is used for improved farmer’s decision-making to combat the negative impacts of climate variability and change.

Goal number three of the SDGs agenda pertains to health by stating “Ensure healthy lives and promote well-being for all at all ages” and goal number seventeen pertains to intersectoral collaboration stating “Strengthen the means of implementation and revitalize the global partnership for sustainable development”. HIA is a cross-cutting tool between sectors where health-related targets are considered in developments across all sectors.
The Technical Support Team’s ‘Issue Brief on Health and Sustainable Development’ pertains to the central role of health in the economic, social and environmental dimensions of sustainable development. A health-in-all-sectors approach is established, where health-related targets are to be considered in developments across all sectors accompanied by monitoring of health outcome and health-related indicators. The monitoring of health impacts has explicitly been declared as one of the five priorities in the framework of the SDGs and governments, scientists and private sectors are called to routinely release their data. Therefore, HIA perfectly adheres to and applies principles and approaches emphasised in the SDG agenda.
