Learning to treat the climate emergency together: social tipping interventions by the health community.

Accelerating the decarbonisation of local and national economies is a profound public health imperative. As trusted voices within communities around the world, health professionals and health organisations have enormous potential to influence the social and policy landscape in support of decarbonisation. We assembled a multidisciplinary, gender-balanced group of experts from six continents to develop a framework for maximising the social and policy influence of the health community on decarbonisation at the micro levels, meso levels, and macro levels of society. We identify practical, learning-by-doing approaches and networks to implement this strategic framework. Collectively, the actions of health-care workers can shift practice, finance, and power in ways that can transform the public narrative and influence investment, activate socioeconomic tipping points, and catalyse the rapid decarbonisation needed to protect health and health systems.

Carbon emissions and hospital pathology stewardship: a retrospective cohort analysis.

BACKGROUND: As healthcare is responsible for 7% of Australia's carbon emissions, it was recognised that a policy implemented at St George Hospital, Sydney, to reduce non-urgent pathology testing to 2 days per week and, on other days only if essential, would also result in a reduction in carbon emissions. The aim of the study was to measure the impact of this intervention on pathology collections and associated carbon emissions and pathology costs. AIMS: To measure the impact of an intervention to reduce unnecessary testing on pathology collections and associated carbon emissions and pathology costs. METHODS: The difference in the number of pathology collections, carbon dioxide equivalents (CO2 e) for five common blood tests and pathology cost per admission were compared between a 6-month reference period and 6-month intervention period. CO2 e were estimated from published pathology CO2 e impacts. Cost was derived from pathology billing records. Outcomes were modelled using multivariable negative binomial, generalised linear and logistic regression. RESULTS: In total, 24 585 pathology collections in 5695 patients were identified. In adjusted analysis, the rate of collections was lower during the intervention period (rate ratio 0.90; 95% confidence interval (CI), 0.86-0.95; P < 0.001). This resulted in a reduction of 53 g CO2 e (95% CI, 24-83 g; P < 0.001) and $22 (95% CI, $9-$34; P = 0.001) in pathology fees per admission. The intervention was estimated to have saved 132 kg CO2 e (95% CI, 59-205 kg) and $53 573 (95% CI, 22 076-85 096). CONCLUSIONS: Reduction in unnecessary hospital pathology collections was associated with both carbon emission and cost savings. Pathology stewardship warrants further study as a potentially scalable, cost-effective and incentivising pathway to lowering healthcare associated greenhouse gas emissions.

Environmental Sustainability in the Cardiac Catheter Laboratory.

The health care sector contributes to nearly 5% of global carbon emissions with the exponential growth of medical waste posing a significant challenge to environmental sustainability. As the impact of climate change on individuals and population health becomes increasingly more apparent, the health care system's significant impact on the environment is also raising concerns. Hospitals contribute disproportionately to health care waste with the majority arising from resource intensive areas such as operating theatres and cardiac catheter labs (CCLs). Despite the growing volume of cardiac procedures worldwide, initiatives to reduce waste from CCLs have received limited attention, overlooking opportunities for significant reduction in operational costs and carbon footprint. We aim to raise awareness of the current landscape of waste management in CCLs. We identify areas of resource optimisation and highlight practical strategies and frameworks employed elsewhere in health care to reduce waste. Importantly, we hope to empower health care workers in CCLs to make a meaningful change to their practice and contribute towards a more sustainable future.

The carbon footprint of hospital diagnostic imaging in Australia.

Background: Pathology testing and diagnostic imaging together contribute 9% of healthcare's carbon footprint. Whilst the carbon footprint of pathology testing has been undertaken, to date, the carbon footprint of the four most common imaging modalities is unclear. Methods: We performed a prospective life cycle assessment at two Australian university-affiliated health services of five imaging modalities: chest X-ray (CXR), mobile chest X-ray (MCXR), computerised tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US). We included scanner electricity use and all consumables and associated waste, including bedding, imaging contrast, and gloves. Analysis was performed using both attributional and consequential life cycle assessment methods. The primary outcome was the greenhouse gas footprint, measured in carbon dioxide equivalent (CO2e) emissions. Findings: Mean CO2e emissions were 17·5 kg/scan for MRI; 9·2 kg/scan for CT; 0·8 kg/scan for CXR; 0·5 kg/scan for MCXR; and 0·5 kg/scan for US. Emissions from scanners from standby energy were substantial. When expressed as emissions per additional scan (results of consequential analysis) impacts were lower: 1·1 kg/scan for MRI; 1·1 kg/scan for CT; 0·6 kg/scan for CXR; 0·1 kg/scan for MCXR; and 0·1 kg/scan for US, due to emissions from standby power being excluded. Interpretation: Clinicians and administrators can reduce carbon emissions from diagnostic imaging, firstly by reducing the ordering of unnecessary imaging, or by ordering low-impact imaging (X-ray and US) in place of high-impact MRI and CT when clinically appropriate to do so. Secondly, whenever possible, scanners should be turned off to reduce emissions from standby power. Thirdly, ensuring high utilisation rates for scanners both reduces the time they spend in standby, and apportions the impacts of the reduced standby power of a greater number of scans. This therefore reduces the impact on any individual scan, maximising resource efficiency.

Climate change is a health issue: what can doctors do?

The visit to Australia by Dr David Pencheon, Founding Director of the National Health Service (NHS) Sustainable Development Unit, in April-May 2018 generated considerable interest and engagement. Dr Pencheon's overarching messages were that climate change is a health issue and that doctors and health systems have an opportunity, and responsibility, to lead climate action. This article distils Dr Pencheon's presentations into three themes: (i) carbon accounting; (ii) transformational change in our systems of healthcare; and (iii) a health system fit for the future. For each theme, we highlight promising initiatives that are already underway in Australia that are starting to transform our health system into one fit for a future environmentally sustainable world. We suggest practical ways in which doctors can lead the transformation through personal action and influence broader systems.

Healthcare in a carbon-constrained world.

Objective The climate crisis necessitates urgent decarbonisation. The health sector must address its large carbon footprint. In the present study, we sought healthcare thought leaders' views about a future environmentally sustainable health system. Methods The present study was a qualitative exploratory study consisting of semistructured, in-depth interviews with 15 healthcare thought leaders from Australia, the UK, the US and New Zealand. Audio recordings of the interviews were transcribed and analysed by matrix display and thematic analysis. Results Overall, healthcare thought leaders believe that to reduce the carbon footprint of healthcare we need to look beyond traditional 'green' initiatives towards a more fundamental and longer-term redesign. Five main themes and one 'key enabler' (information communication technology) were identified. In this paper we draw on other relevant findings, but chiefly focus on the fifth theme about reshaping the role of healthcare within society and using the size and influence of the health sector to leverage wider health, environmental and societal benefits. Conclusions These ideas represent potentially low-carbon models of care. The next step would be to pilot and measure the outcomes (health, environmental, financial) of these models. What is known about the topic? The health sector needs to reduce its large carbon footprint. Traditional 'green' initiatives, such as recycling and improving energy efficiency, are insufficient to achieve the scale of decarbonisation required. What does this paper add? Healthcare thought leaders surveyed in the present study suggested that we also consider other, non-traditional ways to achieve environmental sustainability. In this paper we discuss their ideas about adopting an anticipatory approach to healthcare using predictive analytics, and using the size and influence of the health sector to effect wider health and environmental benefits. What are the implications for practitioners? Achieving an environmentally sustainable healthcare system is likely to require broad and fundamental (i.e. transformational) change to the current service model. Health practitioners throughout the sector must be closely engaged in this process.

Addressing the carbon footprint of health organisations: eight lessons for implementation.

BACKGROUND: The scientific evidence for global warming is overwhelming. Health organisations, as large carbon polluters, are at significant 'carbon risk' and must act to reduce their carbon emissions. Many environmental sustainability initiatives, if properly implemented, would not only reduce harm, waste and pollution but also deliver health, social and financial benefits. METHOD: We have been involved for more than a decade in efforts to reduce the greenhouse gas emissions of New South Wales (NSW) Health organisations in which we have worked. We draw on our collective experience to offer eight key lessons about implementing environmental sustainability initiatives in health organisations. RESULTS: Sustainability plans have been developed in at least three Area Health Services/Local Health Districts in NSW, but in each case they have been imperfectly implemented. LESSONS LEARNT: Based on our experience, we offer eight key lessons relating to leadership, engagement and developing networks, data, complex adaptive systems, broadening the issue, and political factors.

New sources of value for health and care in a carbon-constrained world.

Background: Due to the climate crisis, it is increasingly evident that countries will have to decarbonize. Healthcare, which has a large carbon footprint and uses vast quantities of resources, will have to undergo significant transformation. In this research, we sought the ideas of leading thinkers in the field, to address the question of how health systems can provide high-quality care in a carbon-constrained world. Methods: Semi-structured, qualitative in-depth interviews with 15 healthcare thought leaders from Australia, the UK, the USA and New Zealand. The interviews were transcribed and analysed by matrix display and thematic analysis. Results: 'Green' initiatives such as improving energy efficiency and implementing travel plans will be insufficient to achieve the scale of decarbonization required. According to the thought leaders in our study, it is likely that greater carbon and resource savings will come from thinking much more broadly about innovative models of care and using 'new' sources of 'value' such as 'people' and 'relationships'. Conclusions: Using human resources and human interactions as low-carbon sources of value in healthcare are promising models.

Transformational change in healthcare: an examination of four case studies.

Objectives Healthcare leaders around the world are calling for radical, transformational change of our health and care systems. This will be a difficult and complex task. In this article, we examine case studies in which transformational change has been achieved, and seek to learn from these experiences. Methods We used the case study method to investigate examples of transformational change in healthcare. The case studies were identified from preliminary doctoral research into the transition towards future sustainable health and social care systems. Evidence was collected from multiple sources, key features of each case study were displayed in a matrix and thematic analysis was conducted. The results are presented in narrative form. Results Four case studies were selected: two from the US, one from Australia and one from the UK. The notable features are discussed for each case study. There were many common factors: a well communicated vision, innovative redesign, extensive consultation and engagement with staff and patients, performance management, automated information management and high-quality leadership. Conclusions Although there were some notable differences between the case studies, overall the characteristics of success were similar and collectively provide a blueprint for transformational change in healthcare. What is known about the topic? Healthcare leaders around the world are calling for radical redesign of our systems in order to meet the challenges of modern society. What does this paper add? There are some remarkable examples of transformational change in healthcare. The key factors in success are similar across the case studies. What are the implications for practitioners? Collectively, these key factors can guide future attempts at transformational change in healthcare.

The future healthcare?

BACKGROUND: Healthcare systems in Australia and around the world are failing to address the challenges ofthe modern world. Healthcare leaders are calling for radical, transformational change and entirely new systems of care. However it is unclear what a future, sustainable healthcare system would look like. METHODS: A narrative review to examine emerging trends in health and social care was conducted. RESULTS AND CONCLUSIONS: Six key trends were identified. Collectively, they suggest that future systems are likely to be characterised by increasingly sophisticated technology, but at the same time greater personal and community responsibility for health and well being, innovative use of social capital, and a new approach to ageing and end-of-life care.

An analysis of subject areas and country participation for all health-related projects in the EU's FP5 and FP6 programmes.

BACKGROUND: Previous analyses concerning health components of European Union (EU)-funded research have shown low project participation levels of the 12 newest member states (EU-12). Additionally, there has been a lack of subject-area analysis. In the Health Research for Europe project, we screened all projects of the EU's Framework Programmes for research FP5 and FP6 (1998-2006) to identify health research projects and describe participation by country and subject area. METHODS: FP5 and FP6 project databases were acquired and screened by coders to identify health-related projects, which were then categorized according to the 47 divisions of the EU Health Portal (N = 2728 projects) plus an extra group of 'basic/biotech' projects (N = 1743). Country participation and coordination rates for projects were also analyzed. RESULTS: Approximately 20% of the 26 946 projects (value €29.2bn) were health-related (N = 4756. Value €6.04bn). Within the health categories, the largest expenditures were cancer (11.9%), 'other' (i.e. not mental health or cardiovascular) non-communicable diseases (9.5%) and food safety (9.4%). One hundred thirty-two countries participated in these projects. Of the 27 EU countries (and five partner countries), north-western and Nordic states acquired more projects per capita. The UK led coordination with > 20% of projects. EU-12 countries were generally under-represented for participation and coordination. CONCLUSIONS: Combining our findings with the associated literature, we comment on drivers determining distribution of participation and funds across countries and subject areas. Additionally, we discuss changes needed in the core EU projects database to provide greater transparency, data exploitation and return on investment in health research.

Environmentally sustainable health care: using an educational intervention to engage the public health medical workforce in Australia.

UNLABELLED: Awareness of the benefits of environmentally sustainable health care is growing. In the United Kingdom in 2010, an educational intervention on sustainable health care was successfully delivered to public health registrars. We conducted a feasibility study to test the intervention in Australia. METHODS: The intervention consisted of a 1-day workshop delivered face-to-face covering climate change, sustainability and health. The workshop was modified, piloted and then delivered to 33 health professionals. Modifications included using Australian resources, introducing active learning exercises and including guest speakers. Delivery by videoconference was trialled. Outcomes were assessed in three areas - awareness, advocacy and action - using questionnaires and follow-up telephone interviews. RESULTS: There were improvements in participants' mean awareness and advocacy scores. All participants rated sustainability as 'important' for health professionals and many looked to their professional organisation to take a lead advocacy role on this issue. DISCUSSION: This study demonstrated that the workshop is feasible for use in Australia; the modifications and delivery by videoconference were well received.

Health impacts of increasing alcohol prices in the European Union: a dynamic projection.

OBJECTIVE: Western Europe has high levels of alcohol consumption, with corresponding adverse health effects. Currently, a major revision of the EU excise tax regime is under discussion. We quantify the health impact of alcohol price increases across the EU. DATA AND METHOD: We use alcohol consumption data for 11 member states, covering 80% of the EU-27 population, and corresponding country-specific disease data (incidence, prevalence, and case-fatality rate of alcohol related diseases) taken from the 2010 published Dynamic Modelling for Health Impact Assessment (DYNAMO-HIA) database to dynamically project the changes in population health that might arise from changes in alcohol price. RESULTS: Increasing alcohol prices towards those of Finland (the highest in the EU) would postpone approximately 54,000 male and approximately 26,100 female deaths over 10 years. Moreover, the prevalence of a number of chronic diseases would be reduced: in men by approximately 97,800 individuals with diabetes, 65,800 with stroke and 62,200 with selected cancers, and in women by about 19,100, 23,500, and 27,100, respectively. CONCLUSION: Curbing excessive drinking throughout the EU completely would lead to substantial gains in population health. Harmonisiation of prices to the Finnish level would, for selected diseases, achieve more than 40% of those gains.

Developing an environmentally sustainable NHS: outcomes of implementing an educational intervention on sustainable health care with UK public health registrars.

UNLABELLED: Environmental sustainability is a new and fast moving field in health. There is little evidence about how to teach it effectively to health professionals. METHODS: We conducted a pilot study of an educational intervention with more than 200 UK public health registrars. The intervention consisted of a day-long workshop with the aim of training participants to help make the UK's National Health Service more environmentally sustainable. RESULTS: We measured outcomes in three areas: awareness, advocacy and actions. Comparison of baseline and post intervention questionnaire scores showed statistically significant improvements in the awareness and advocacy scores. Actions were assessed qualitatively. Our findings suggest that, while there are some pockets of good practice, many health professionals are yet to engage with sustainability in the workplace. DISCUSSION: We propose reasons why health professionals are yet to become involved in sustainability issues despite the related opportunities for health and health services.

Difficulties of tracing health research funded by the European Union.

OBJECTIVE: European Union (EU) information from research projects, including key findings, should be available on the European Commission's Community Research and Development Information Service (CORDIS) database. We describe the results of the Health Research for Europe (HR4E) project which aimed to synthesize results of health research from the EU's Fifth and Sixth Framework Programmes (FP5 and FP6) of research. METHODS: Screening of titles and abstracts of all projects funded within FP5 and FP6 to identify health-related projects followed by allocation of such projects to one of the 47 themes of the European Union's Health Portal. Extraction of key findings relevant for policy and practice from data on the CORDIS database and, in a subset of 182 projects selected from five themes, attempted contact with project co-ordinators to obtain missing information. RESULTS: The information held on CORDIS was inadequate, with many fields not completed. Data were rarely updated after the project had been funded. Of the 182 attempts to contact co-ordinators, useful information was obtained in only 17% of cases, with many contact details missing or unverifiable. CONCLUSIONS: CORDIS does not meet its stated objectives of facilitating and disseminating EU research. There is a clear need to review the systems designed to manage the CORDIS platform.
