Background People who smoke crack cocaine face significant health risks, including communicable diseases and damage to respiratory health, particularly when using shared or homemade equipment. Despite this, there are currently no targeted harm reduction interventions in Wales for this population. This unique study demonstrates how Health Impact Assessment (HIA) can be used as a process to highlight the wider impacts of a proposed harm reduction pilot of the provision of safer inhalation devices (SIDs) in Wales, and how it has informed future actions and implementation of the scheme. Methods A participatory HIA was conducted using a structured process facilitated by the Wales Health Impact Assessment Support Unit (WHIASU). Stakeholder engagement included a workshop involving service providers, public health professionals, and individuals with lived experience of crack cocaine use. The process utilised HIA checklists to systematically assess the potential health, social, and economic impacts of implementing a SIDs pilot, as well as unintended consequences. Results The HIA identified a range of positive impacts associated with SIDs, including reduced risk of infections, decreased use of unsafe inhalation equipment, and increased service engagement. Participants emphasised the intervention’s potential to reduce stigma and enhance trust, particularly for women, parents, and individuals with a history of adverse childhood experiences. Challenges were also recognised, including potential service strain, funding sustainability, and access barriers for rural populations. Suggested mitigations included mobile outreach and home delivery models. The HIA also highlighted the importance of including lived and living experience to inform future monitoring and service design. Conclusion This HIA underscores the potential value of an SID pilot in Wales as a means of addressing a critical service gap and reducing health inequalities among people who smoke crack cocaine. It demonstrates the utility of HIA in identifying both potential positive and negative impacts, and in shaping harm reduction strategies that are inclusive, and evidence informed. The findings provide a foundation for pilot implementation and evaluation, as well as a model for integrating HIA into broader public health initiatives and holistic harm reduction services.

Background Health Impact Assessment (HIA) is promoted as a decision-informing tool by public health and governmental agencies. HIA is beneficial when carried out as part of policy development but is also valuable as a methodology when a policy is being implemented to identify and understand the wider health and well-being impacts of policy decisions, particularly when a decision needs to be taken rapidly to protect the population. This paper focusses on a HIA of the ‘Staying at Home and Social Distancing Policy’ or ‘lockdown’ in response to the COVID-19 pandemic in Wales conducted by the Welsh national public health institute. It describes the process and findings, captures the learning and discusses how the process has been used to better understand the wider health and well-being impacts of policy decisions beyond direct health harm. It also examines the role of public health institutes in promoting and using HIA. Methods A HIA was conducted following a standard HIA five step process. A literature review was undertaken alongside 15 qualitative semi-structured interviews with key stakeholders, and relevant health and demographic data were collated. The results were triangulated and analysed to form a holistic assessment of the policy decision and its impacts. Results A wide range of major health and well-being impacts of the lockdown in Wales were identified across the determinants of health, which included positive and negative social, economic, environmental and mental well-being impacts beyond the impact on direct health. Populations affected included children and young people, those on low incomes and women as well as those whose health has been directly impacted by COVID-19 such as older people. The work highlighted the benefit that HIA can bring in emphasizing impacts which can inform policy and shared learning with others. Conclusion HIA is a largely underused tool to understand the impact of policy and political decisions, particularly when a decision has been taken at speed. This case study highlights how HIA provide evidence and information for advocacy and further work by public health institutes, health agencies and policy makers.

Background Health Impact Assessment (HIA) advances Health in All Policies by identifying impacts of proposed actions on health and equity and recommending changes to address these impacts. Since the Gothenburg Consensus Statement in 1999, HIA has been applied to policies, plans, programmes and projects in multiple sectors and settings across the world. Despite demonstrated effectiveness, its use across the world is inconsistent with few nations systematically using HIA. In a global context of increasing health inequities, pandemics, climate change, and economic crises, HIA can help integrate health and equity into decision making. There is a need for research to support the ongoing evolution and development of HIA. This paper presents a research agenda for the field of HIA. Methods We used a mixed method approach utilising insights of approximately 280 participants through an international online survey and participatory workshops. We compared priority areas of research identified through the survey, workshops, and literature review to inform the development of a research agenda. The team drew on their own positioning and experience as HIA practitioners and researchers to shape this agenda. Results We identified four research priorities: (1) Institutionalisation - Sustaining and institutionalising HIA in varying contexts and levels. (2) Influence - Identifying mechanisms and strategies that can be employed to effectively influence stakeholders and decision making. (3) Equity and Participation - Analysing the role of equity, justice, power and participation in HIA, and (4) Methodology - Improving HIA Methods to understand the complex relationships between proposed actions, health and health equity outcomes and identifying what to do. We developed research questions for each theme. Conclusions The research agenda advocates for sustained research and practice to strengthen impact and address knowledge gaps in the field. Functioning as a roadmap for both researchers and funders, it aims to contribute to a healthier and more equitable world. Recognising the valuable role of HIA in addressing global health challenges, the agenda encourages researchers to investigate, develop, and advance the field of HIA.

Microbial biotechnologies could affect health through multiple pathways, including impacts on food, nutrition, and the physical, economic, and social environment. Health in All Policies is an approach to ensure that plans and policies in all sectors maximise health gains and minimise any health risks. This approach often uses health impact assessment as a structured process to identify and assess positive and negative health impacts and make recommendations to improve these. There are very few examples where HIA has been applied to the implementation of microbial biotechnologies. As more biotechnologies are developed and implemented, more routine use of HIA could help to avoid adverse effects and realise their potential to improve health and reduce health inequalities. This will require greater awareness and understanding of the breadth of links to health, research to build the evidence base for these links, and governance mechanisms to oversee the development and implementation of microbial biotechnologies that prioritise health, equity and sustainability. Applying Health in All Policies to the development and application of microbial biotechnologies can identify and address a range of possible health determinants.

Objective: Climate change is recognised as the biggest threat to global health of the 21st century and impacts on health and wellbeing through a range of factors. Due to this, the need to take action in order to protect population health and wellbeing is becoming ever more urgent. Methods: In 2019, Public Health Wales carried out a comprehensive mixed-method Health Impact Assessment (HIA) of climate change. Unlike other risk assessments, it appraised the potential impact of climate change on health and inequalities in Wales through participatory workshops, stakeholder consultations, systematic literature reviews and case studies. Results: The HIA findings indicate potential impacts across the wider determinants of health and wellbeing. For example, air quality, excess heat/cold, flooding, economic productivity, infrastructure, and community resilience. A range of impacts were identified across population groups, settings, and geographical areas. Conclusion: These findings can inform decision-makers to prepare for climate change plans and policies using an evidence-informed approach. The work has demonstrated the value of a HIA approach by mobilising a range of evidence through a transparent process, resulting in transferrable learning for others.

Policy in all sectors affects health, through multiple pathways and determinants. Health in all policies (HiAP) is an approach that seeks to identify and influence the health and equity impacts of policy decisions, to enhance health benefits and avoid harm. This usually involves the use of health impact assessment or health lens analysis. There is growing international experience in these approaches, and some countries have cross-sectoral governance structures that prioritize the assessment of the policies that are most likely to affect health. The fundamental elements of HiAP are inter-sectoral collaboration, policy influence, and holistic consideration of the range of health determinants affected by a policy area or proposal. HiAP requires public health professionals to invest time to build partnerships and engage meaningfully with the sectors affecting the social determinants of health and health equity. With commitment, political will and tools such as the health impact assessment, it provides a powerful approach to integrated policymaking that promotes health, well-being, and equity. The COVID-19 pandemic has raised the profile of public health and highlighted the links between health and other policy areas. This paper describes the rationale for, and principles underpinning, HiAP mechanisms, including HIA, experiences, challenges and opportunities for the future.

Green shares her experience of working in a residential rehab. In a single year, hundreds of souls passed through the facility where she worked, which housed 25 women at a time. It was an all-female residential rehab in an aging house in New Orleans LA, a neighborhood of rundown Victorians and lush, sheltering oaks. They referred to residents as \"clients\" or \"the Ladies.\" Clients had come to them from mental hospitals, shelters, and detox, from living under the Claiborne Avenue overpass. Some stayed barely 24 hours.

The food environment has taken on much of the impact of the COVID-19 pandemic. Evidence shows people's relationship and access to the food environment is a determinant of their health and wellbeing, and in relation to prevalence of chronic and non-communicable diseases. The spatial planning system forms part of a whole systems action in shaping the environment in a way that maximises population health gain. While these practices have had varying degrees of success, the sudden introduction and spread of COVID-19, and the responses to it, has forced us to re-examine the utility of current planning practice, particularly the impact on inequalities. In this commentary we aim to explore the post-pandemic role of spatial planning as a mechanism for improving public health by highlight a whole system perspective on the food environment, referring to experiences in Wales as a case study, and concluding with observation on future consumer trends around access to food.

Health Impact Assessment is a key approach used internationally to identify positive or negative impacts of policies, plans and proposals on health and well-being. In 2020, HIAs were undertaken in Scotland and Wales to identify the potential health and well-being impacts of the ‘stay at home’ and physical distancing measures implemented at the start of the coronavirus disease (COVID-19) pandemic. There is sparse evidence evaluating whether the impacts predicted in HIAs occur following policy implementation. This paper evaluates the impacts anticipated in the COVID-19 HIAs against actual observed trends. The processes undertaken were compared and predicted impacts were tabulated by population groups and main determinants of health. Routine data and literature evidence were collated to compare predicted and observed impacts. Nearly all health impacts anticipated in both HIAs have occurred in the direction predicted. There have been significant adverse impacts through multiple direct and indirect pathways including loss of income, social isolation, disruption to education and services, and psychosocial effects. This research demonstrates the value of prediction in impact assessment and fills a gap in the literature by comparing the predicted impacts identified within the HIAs with observed trends. Post-COVID-19 recovery should centre health and well-being within future policies and decisions. Processes like HIA can support this as part of a ‘health in all policies’ approach to improve the health and well-being of populations.

In June 2016, the UK voted to leave the European Union (EU) in a process known as Brexit, which is surrounded by political and social uncertainty. We aimed to assess the potential impact of Brexit on Wales. Using health impact assessment methodology steered by a Strategic Advisory Group, we did a comprehensive mixed-method health impact assessment between July 2, 2018, and Jan 21, 2019. We searched MEDLINE, Embase, and Proquest databases using the well-established PICO (population, intervention, comparator, and outcome) framework used in evidence-based practice to frame and answer a health-care related question, to identify peer-reviewed literature published after January 2016, on the potential impact of Brexit on health and the economy. We supplemented the search with a review of grey literature on direct impacts, such as the environment, health care, and EU funding. Additionally, we held a stakeholder workshop including cross-sectoral representation such as housing, environmental health and planning, qualitative interviews with policy leads, and developed a community health profile using recognised data sources (eg, the National Survey for Wales) to understand the different population groups. The findings were analysed, synthesized, and collated into a published report. The health impact assessment identified considerable potential impacts across the wider determinants of health, including effects across vulnerable population groups, mental wellbeing, and geographical areas in Wales that receive EU funding. Trade agreements, changing relationships with EU agencies, uncertainty, and loss of regulatory alignment were identified as key pathways for health impacts. For example, trade agreements can improve the supply and choice of food, but can also result in trade liberalisation and increased imports of highly-processed foods. Another example is the impact on food safety due to workforce challenges (ie, the low number of certificating officers at abattoirs who are UK-national citizens). Since Brexit is yet to occur, the impacts identified are potential. Although this assessment was done over a short period of time, the findings have been beneficial in informing decision makers to prepare for Brexit using an evidence-informed approach. This work highlights the value of a health impact assessment approach to unprecedented events by mobilising a wide range of evidence through a transparent process, resulting in transferrable learning for others.
