A comparison of the carbon footprint of alternative sampling approaches for cervical screening in the UK: A descriptive study.

OBJECTIVE: To understand whether self-sampling can reduce carbon emissions (CO2 e) from the NHS cervical screening programme (NHSCSP) by comparing the carbon footprint of three sampling strategies: routine cervical sampling, vaginal self-sampling and first-void (FV) urine collection. DESIGN: Descriptive study. SETTING: National Health Service (NHS), United Kingdom (UK). POPULATION OR SAMPLE: Patients aged 25-64 years eligible for cervical screening in the UK. METHODS: A carbon footprint analysis was undertaken for three cervical screening sampling approaches, from point of invitation to screening through to preparation for transport to the laboratory for HPV testing. A combination of primary and secondary data were used, with a bottom-up approach applied to collection of primary data. MAIN OUTCOME MEASURES: We report CO2 e per sampling approach, which is the unit used to express carbon footprint and harmonise the contributions of greenhouse gases with different global warming potentials. RESULTS: The total carbon footprint of routine cervical sampling is 3670 g CO2 e. By comparison, vaginal self-sampling had a total carbon footprint of 423 g CO2 e, and FV urine sampling 570 g CO2 e. The largest share of emissions for routine sampling was attributable to the carbon footprint associated with an appointment in a primary care setting, which totalled 2768 g CO2 e. CONCLUSIONS: Routine cervical sampling is up to 8.7-fold more carbon-intensive than self-sampling approaches with equivalent effectiveness. We found negligible differences in the carbon footprint of alternative self-sampling methods, supporting the need for an informed choice of screening options for participants, which includes sharing information on their environmental impacts.

Single-use synthetic plastic and natural fibre anaesthetic drug trays: a comparative life cycle assessment of environmental impacts.

BACKGROUND: Single-use anaesthetic drug trays are used widely in Australia, but their environmental impact is unclear. METHODS: A life cycle assessment was completed for 10 different types of single-use anaesthetic drug trays made of four materials: the synthetic plastics polypropylene and polystyrene, and the natural fibres bagasse (sugarcane pulp) and cellulose pulp. RESULTS: Carbon emissions per tray from total life cycle with landfill disposal were 33-454 g CO2-eq, which equates to 152-2066 tonnes CO2-eq annually. Recycling mitigates this impact, reducing emissions per tray to 16-294 g CO2-eq. The tray with the least emissions for landfill and recycling was the small polystyrene injection tray. There was a significant linear relationship between the mass of a tray and its carbon emissions. For landfill, recycling, and incineration disposal, Pearson's r value was 0.98, 0.99, and 0.95, respectively. Composting natural fibres can give a carbon benefit over some synthetic plastics under specific disposal scenarios, but this benefit was not seen under all circumstances. There was a strong positive correlation between the increasing mass of a tray and its increasing environmental impacts for water consumption, particulate matter formation, and mineral depletion. CONCLUSIONS: Single-use trays with the lowest mass should be preferentially chosen. Recycling and composting will reduce environmental impacts. Natural fibre does not automatically confer any environmental benefit over plastic and sustainability claims should be carefully examined for accuracy. The practice of using a single-use drug tray for every procedure should be reconsidered.

Unwarranted variation and the goal of net zero for the NHS in England: exploring the link between efficiency working, patient outcomes and carbon footprint.

In 2020 the NHS in England set a target of reaching net zero carbon emissions by 2040. Progress has already been made towards this goal, with substantial reductions in the use of environmentally harmful anaesthetic gases, such as desflurane, in recent years. Where an effective replacement already exists, changing practice to use low carbon alternatives is relatively easy to achieve, but much greater challenges lie ahead. The Getting It Right First Time (GIRFT) programme is a clinically-led, data-driven clinical improvement initiative with a focus on reducing unwarranted variation in clinical practice and patient outcomes. Reducing unwarranted variation can improve patient care and service efficiency, and can also support the drive to net zero. In this article we set out what the GIRFT programme is doing to support sustainable healthcare in England, why it is uniquely positioned to support this goal and what the future challenges, barriers, enablers and opportunities are likely to be in the drive to net zero.

Transitioning to sustainable, climate-resilient healthcare: insights from a health service staff survey in Australia.

BACKGROUND: More than 80 countries, including Australia, have made commitments to deliver climate-resilient and low carbon healthcare. Understanding how healthcare workers view their own and their organization's efforts to achieve sustainable and climate-resilient healthcare practice is vital to inform strategies to accelerate that transition. METHODS: We conducted an online staff survey in a large state government hospital-and-health-service organisation in Queensland, Australia, to ascertain attitudes and practices towards environmentally sustainable, climate-resilient healthcare, and views about the organizational support necessary to achieve these goals in their workplace. RESULTS: From 301 participants showed staff strongly support implementing sustainable and climate-resilient healthcare but require significantly more organizational support. Participants identified three categories of organizational support as necessary for the transition to environmentally sustainable and climate-resilient health services and systems: (1) practical support to make sustainability easier in the workplace (e.g. waste, energy, water, procurement, food, transport etc.); (2) training and education to equip them for 21st century planetary health challenges; and (3) embedding sustainability as 'business as usual' in healthcare culture and systems. CONCLUSIONS: The research provides new insight into health workforce views on how organizations should support them to realize climate and sustainability goals. This research has implications for those planning, managing, implementing, and educating for, the transition to environmentally sustainable and climate-resilient health services and systems in Queensland, Australia, and in similar health systems internationally.

Australian and New Zealand nursing and midwifery educators' planetary health knowledge, views, confidence and teaching practices: A descriptive survey study.

AIM: To explore Australian and New Zealand nursing and midwifery educators' planetary health knowledge, views, confidence and teaching practices. DESIGN: A cross-sectional survey design. METHODS: An online survey was sent to Australian and New Zealand nursing and midwifery educators across the 45 Schools of Nursing and Midwifery between July and September 2023. The online survey consisted of 29 open- and closed-ended questions about nursing and midwifery educators' planetary health knowledge, views, confidence and teaching practices. RESULTS: There was a total of 127 responses to the first open-ended question. A total of 97 nursing and midwifery educators then completed the remaining questions. While educators had mostly positive views about integrating planetary health into their teaching, they lacked the knowledge and/or confidence to do so effectively. CONCLUSION: Australian and New Zealand nursing and midwifery educators acknowledge that planetary health should be included in nursing and midwifery curricula, but most reported a deficit in knowledge and/or confidence to integrate these complex concepts into their teaching. When considering planetary health, most educators focussed on climate change, which demonstrates their limited understanding of the concept of planetary health. IMPLICATIONS FOR THE PROFESSION: All nurses and midwives need to understand how the health of the planet and human civilization are interconnected and be prepared to address complex global health challenges now and in the future. Across the world, key healthcare organizations have called upon nursing and midwifery educators to prepare the healthcare workforce to practice in a more sustainable way, including supporting decarbonization of healthcare. However, our study has demonstrated that nursing and midwifery educators do not feel ready to respond due to a lack of required knowledge and/or confidence. REPORTING METHOD: We used the Consensus-Based Checklist for Reporting of Survey Studies (CROSS). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Stratification of Outpatient Physical Therapy Following Total Knee Arthroplasty: Knee Arthroplasty Physical Therapy Pathways (KAPPA) Nonrandomized Controlled Trial.

BACKGROUND: Outpatient physical therapy following total knee arthroplasty (TKA) is often considered crucial for an effective recovery. However, recent evidence suggests that a self-directed pathway may yield similar benefits to supervised care. Despite this, there appear to be no established criteria to determine who can successfully self-direct their rehabilitation versus those who would benefit from outpatient physical therapy. This study aimed to determine if early postoperative criteria can stratify TKA patients into a self-directed or supervised physical therapy pathway without compromising outcomes. METHODS: Overall, 60 TKA patients were initially allocated to a self-directed, unsupervised protocol for their postoperative rehabilitation. Baseline demographics, along with functional and self-reported outcomes, were assessed preoperatively and at 2 weeks, 6 weeks, and 4 months following surgery. Patients were referred to supervised outpatient physical therapy if they met any of the following Knee Arthroplasty Physical Therapy Pathways (KAPPA) criteria: (1) knee flexion range of motion <90 degrees; (2) knee extension range of motion lacking >10 degrees; or (3) dissatisfaction with the progress of their rehabilitation. RESULTS: At 2 weeks post-TKA, 28 participants met the KAPPA criteria for supervised physical therapy for reasons of knee flexion <90 degrees (61%), a lack of knee extension >10 degrees (36%), or not being satisfied with the progress of their recovery (3%). The remaining 32 participants continued with a self-directed rehabilitation pathway. All outcomes assessed favored the self-directed group at 2 weeks, however, after an average of 4 supervised physical therapy sessions at 4 months there were no longer any differences between the 2 groups. CONCLUSIONS: Over half of the included participants could self-direct their rehabilitation following TKA without supervised physical therapy while also maintaining excellent clinical outcomes. For those who met KAPPA criteria at 2 weeks post-TKA, 4 supervised physical therapy sessions appeared to be beneficial when outcomes were reassessed at 4 months.

Understanding Miscarriage Prevalence and Risk Factors: Insights from Women in Jordan.

Background and Objectives: Miscarriage is a complication that is influenced by many risk factors that have been reported in different studies and that vary among countries. Despite the influence of various known risk factors for miscarriage, 30% to 50% of miscarriages are from unidentified causes. The aim of this study is to determine the prevalence of miscarriages in Jordan and the associated risk factors. Materials and Methods: A cross-sectional online survey was conducted in Jordan among married women to investigate the prevalence of miscarriages and identify potential risk factors. Results: Women (n = 704) were surveyed, and 17.9% reported a history of miscarriage. The identified risk factors were being an active smoker during pregnancy, having more than four children, having a family history of miscarriage, having fertility problems, receiving medical assistance for conception, and traveling by air during pregnancy. Conclusions: The results suggest that there are both modifiable and non-modifiable risk factors for miscarriages in Jordan and that a proportion of these may be preventable. The findings can be used to enhance patient awareness and inform policy development to decrease the incidence of miscarriage in the country.

Exploring the sustainable impacts of a clinical healthcare research scholarship programme.

BACKGROUND: The NHS is the first public body globally to commit to net zero. AIM: This study aimed to explore the environmental sustainability impact of a hospital scholarship programme. METHOD: A sustainable quality improvement value framework was used to measure the programme's environmental, social and financial effects. RESULTS: The social impact through face-to-face contact was most valued by scholars; there were also savings in carbon emissions and costs. DISCUSSION: Training in sustainability is essential for the workforce but little infrastructure and expertise are available within organisations to support staff to provide sustainable healthcare in day-to-day practice. CONCLUSION: Sustainable healthcare should be supported by education and national guidance and implementation plans should be drawn up to this end. The social impact of the framework used is often seen as less important than its environmental and financial components; however, as its value to scholars illustrates, the components are intertwined and should be considered of equal importance.

Climate change, health and sustainable healthcare: The role of health economics.

Healthcare systems around the world are responding with increasing urgency to rapidly evolving ecological crises, most notably climate change. This Perspective considers how health economics and health economists can best contribute to protecting health and building sustainable healthcare systems in the face of these challenges.

Recent advances in nanobiosensors for sustainable healthcare applications: A systematic literature review.

The need for novel healthcare treatments and drugs has increased due to the expanding human population, detection of newer diseases, and looming pandemics. The development of nanotechnology offers a platform for cutting-edge in vivo non-invasive monitoring and point-of-care-testing (POCT) for rehabilitative disease detection and management. The advancement and uses of nanobiosensors are currently becoming more common in a variety of scientific fields, such as environmental monitoring, food safety, biomedical, clinical, and sustainable healthcare sciences, since the advent of nanotechnology. The identification and detection of biological patterns connected to any type of disease (communicable or not) have been made possible in recent years by several sensing techniques utilizing nanotechnology concerning biosensors and nanobiosensors. In this work, 2218 articles are drawn and screened from six digital databases out of which 17 were shortlisted for this review by using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) technique. As a result, this study uses a systematic methodology to review some recently developed extremely sensitive nanobiosensors, along with their biomedical, point-of-care diagnostics (POCD), or healthcare applications and their capabilities, particularly for the prediction of some fatal diseases based on a few of the most recent publications. The potential of nanobiosensors for medicinal, therapeutic, or other sustainable healthcare applications, notably for ailments diagnostics, is also recognized as a way forward in the manifestation of future trends.

Climate change and Australian general practice vocational education: a cross-sectional study.

BACKGROUND: Climate change is a rapidly progressing threat to global health and well-being. For general practitioners (GPs) currently in training, the effects of climate change on public health will shape their future professional practice We aimed to establish the prevalence and associations of Australian GP registrars' (trainees') perceptions of climate change as it relates to public health, education, and workplaces. METHODS: A cross-sectional questionnaire-based study of GP registrars of three Australian training organizations. The questionnaire assessed attitudes regarding adverse health effects of climate change (over the next 10-20 years), and agreement with statements on (i) integrating health impacts of climate change into GP vocational training, and (ii) GPs' role in making general practices environmentally sustainable. RESULTS: Of 879 registrars who participated (response rate 91%), 50.4% (95% CI 46.8%, 54.0%) perceived a large or very large future health effect of climate change on their patients, and 61.8% (95% CI 58.6%, 65.0%) agreed that climate health impacts should be integrated within their education programme. 77.8% (95% CI 74.9%, 80.4%) agreed that GPs should have a leadership role in their practices' environmental sustainability. Multivariable associations of these attitudes included female gender, training region, and (for the latter two outcomes) perceptions of future impact of climate change on patient health. CONCLUSIONS: GP registrars are motivated to receive climate health education and engage in environmentally sustainable practice. This may primarily reflect concern for future practice and patient care.

The 'Clinical Humanities & Wellbeing programme'- sustainable healthcare education for an era of uncertainty.

This article presents a case study where integration of arts and humanities into a clinical programme is being implemented at scale, as core mandatory learning for all students within a UK dental, undergraduate context. The cross-disciplinary programme described, that integrates the Humanities with Clinical Sciences, is a longitudinal professional identity formation curriculum for sustainable oral healthcare which aligns with the UK dental regulator's proposals for a 'safe practitioner' framework for new graduates. The Clinical Humanities & Wellbeing modules embrace the emotional and attitudinal aspects of learning and educate clinical students for the practical wisdom (phronesis) required to deliver 21st century oral healthcare in an era of uncertainty. The overarching aim of the curriculum and its accompanying assessment is to promote critical reflection, student insight and development of integrity, reflexivity, and responsibility. Enabling the subjectification of professional identity formation in this cross-disciplinary way aims to develop students as 'safe practitioners', with increased professional autonomy, responsible for their own actions, and who are better equipped for the uncertainties and phronesis of clinical practice. At present, the programme is being evaluated, employing illuminative evaluation methodology and we present some tentative initial findings. The authors believe that this unique approach and signature pedagogy is, with careful curation, transferrable to other health professions' contexts.

Embedding planetary health concepts in a pre-medical physiology subject.

PURPOSE: There are increasing calls for planetary health (which includes sustainable healthcare) to be included in tertiary health professions education. With already busy curricula, particularly in medicine, educators need to find innovative ways of integrating these important concepts without adding to learners' workload. This study investigated whether planetary health concepts could be integrated into a Physiology subject as a stop-gap approach while longitudinal planning for longitudinal curriculum integration was underway. MATERIALS AND METHODS: Each week, a planetary health fact (Did you know?) with a corresponding link were embedded at the bottom of a relevant PowerPoint lecture slide to match the topic of the week in a health science and medicine Physiology subject. The embedded facts were a mix of effects on health and the environmental impacts of healthcare activities, such as medical imaging. No other formal planetary health teaching was conducted in the subject. At the end of the semester, 44% of 100 students completed a survey regarding their perceptions of the planetary health inclusions. RESULTS: Participants reported an appreciation of the facts, found them helpful for their overall learning, and were interested in learning about healthcare's large environmental footprint. Seventy-one percent were able to provide a reasonable definition of planetary health. Half of the participants reported their actions, behaviours, and thoughts had changed as a result of the planetary health inclusions. CONCLUSIONS: This study provides a relatively simple approach for individual educators to include planetary health concepts into existing health professions subjects until more longitudinal curriculum revisions can be undertaken. Based on our findings, we would, however, recommend providing students with a brief introduction in terms of why planetary health has been included either at the start of the first lecture or as a 10-min video.

Designing a new sustainable Test Kit supply chain network utilizing Internet of Things.

The advent of COVID-19 put much economic pressure on countries worldwide, especially low-income countries. Providing test kits for Covid-19 posed a huge challenge at the beginning of the pandemic. Especially the low-income and less developed countries that did not have the technology to produce this kit and had to import it into the country, which itself cost a lot to buy and distribute these kits. This paper proposes a sustainable COVID-19 test kits supply chain network (STKSCN) for the first time to fill this gap. Distribution and transportation of test kits, location of distribution centers, and management of used test kits are considered in this network. A mixed integer linear programming Multi-Objective (MO), multi-period, multi-resource mathematical model is extended for the proposed supply chain. Another contribution is designing a platform based on the Internet of Things (IoT) to increase the speed, accuracy and security of the network. In this way, patients set their appointment online by registering their personal details and clinical symptoms. An augmented ɛ-constraint2 (AUGMECON2) is proposed for solving small and medium size of problem. Also, two meta-heuristic algorithms, namely NSGA-II and PESA-II are presented to solve the small, medium and large size of the problem. Taguchi method is utilized to control the parameters, and for comparison between meta-heuristic, five performance metrics are suggested. In addition, a case study in Iran is presented to validate the proposed model. Finally, the results show that PESA-II is more efficient and has better performance than the others based on assessment metrics and computational time.

Establishing a sustainable healthcare environment in low- and middle-income countries.

The dynamics of disease prevalence and healthcare systems continue to change dramatically in low- and middle-income countries (LMICs). This is a result of multiple factors including the demands of an ageing population in the context of increasing life expectancy and the rise of non-communicable diseases putting an additional burden on an already weak healthcare system. Further healthcare deficiency is attributable to additional factors such as low financial budgets, political conflicts and civil war, as well as continuing burden of communicable diseases, which are known to be the major risk to health in LMICs. Surgical needs largely remain unmet despite a Lancet report published in 2015. Various deficient aspects of healthcare systems need to be addressed immediately to provide any hope of creating a sustainable healthcare environment in the coming decades. These include developing strong primary and secondary care structures as well as strengthening tertiary care hospitals with an adequately trained healthcare workforce. The facilities required to improve patients' access to healthcare cannot be developed and sustained solely within the local budget allocation and require major input from international organizations such as the World Bank and the World Health Organization as well as a chain of donor networks. To create and retain a local healthcare workforce, improved training and living conditions and greater financial security need to be provided. Finally, healthcare economics need to be addressed with financial models that can provide insurance and security to the underprivileged population to achieve universal health coverage, which remains the goal of several global organizations promoting equity in high-standard healthcare provision.

Spotlight environmental sustainability: a strategic priority for NICE.

This article provides the context for the ambition outlined in the the National Institute for Health and Care Excellence (NICE) 2021-2026 strategy to 'lead globally on the potential to include environmental impact data in its guidance to reduce the carbon footprint of health and care'. Anthropogenic environmental changes pose a catastrophic risk to human health, with potential to widen national and global health inequalities. Recognising the fact that NICE guidance influences the way health and care is delivered and its consequent environmental impact, NICE has included environmental sustainability among its strategic priorities. This article outlines the work underway to meet this sustainability agenda at NICE.

The role of mental health professionals in the climate crisis: an urgent call to action.

The climate and ecological crisis will constitute the defining public health challenge of the twenty-first century, posing an unprecedented global threat to all determinants of health, and to healthcare delivery systems. We believe that mental health professionals have a crucial role to play in responding to this crisis. Whilst responding to the mental health consequences of the climate crisis will remain a key role for us as mental health professionals, we argue that our remit goes beyond this, and should include advancing public understanding of the climate crisis, highlighting its impact on physical and mental wellbeing, and advocating for systemic changes to limit its impending harms. This paper is an urgent call to action for all mental health professionals to take up a role in the context of the climate and ecological crisis. This paper will describe the relationship between mental health and climate change, and frame it within wider systemic and conceptual frameworks. It will demonstrate that as mental health professionals we are well placed to act as leaders of change-arguing that we have a duty to do so-and suggest actions that can be implemented depending on interests, skill sets and opportunities.

Can a multitiered copayment system affect people's healthcare-seeking behavior? A case study of Wenzhou, China.

BACKGROUND: Facilitating the primary health care (PHC) system and maintaining people's reasonable healthcare-seeking behavior are key to establishing a sustainable healthcare system. China has employed a multitiered copayment system/medical insurance differentiated payment policies to incentivize the public to utilize PHC services through its hierarchical medical care system; however, most people still prefer visiting tertiary care hospitals. We question whether the quality gap in healthcare services reduces the effect of the multitiered copayment system, which is considered an important factor in the lack of reform in the Chinese healthcare system. Thus, we explore the effect and influencing factors of the multitiered copayment system that drives primary healthcare-seeking behavior under the current situation with a large quality gap. We also consider the hypothetical situation of a reduced gap in the future. METHODS: This study used the hypothetical quality improvement scenario to elicit people's hypothetical behaviors, and a multistage stratified cluster random sampling method. This preliminary study was conducted in 2016 using 1829 individuals from four regions of Wenzhou in Zhejiang Province: Ouhai, Ruian, Yongjia, and Taishun. A descriptive statistical analysis, chi-square analysis, Fisher's exact test, and multinomial logistic regression model were performed to introduce the effect of the multitiered copayment system, and to explore the factors affecting the selection of PHC institutions at pre- and post-change phases. RESULT: The results show that compared with the large quality gap phase, the number of respondents who believed the multitiered copayment system had an effect on their selection of PHC institutions after the equalization of healthcare services quality increased threefold (from 14.0% to 50.8%). Moreover, the main determinants in people's selection of PHC institutions changed from age and needs variables (self-rated health status) to age, needs variables (self-rated health status) and enabling variables (distance to a medical care facility). CONCLUSION: The results indicate limited initial effects of the multitiered copayment system. However, they become more pronounced after the equalization of healthcare services quality. This study confirms that changes in the quality gap in healthcare services influence the effect of the multitiered copayment system. Hence, reducing this gap can help achieve the intended outcome of the tiered healthcare insurance schedule.

"Concrete ways we can make a difference": A multi-centre, multi-professional evaluation of sustainability in quality improvement education.

Quality improvement (QI) projects are a mandatory part of postgraduate medical training in the UK and graduating medical students must be competent in QI theory. We evaluated an educational toolkit that links concepts of sustainable healthcare with established quality improvement methodologies (the SusQI approach, available at www.susqi.org). The SusQI approach was implemented across a range of undergraduate and postgraduate nursing and medical education contexts. Educational strategies included guided online learning, live interactive webinars, small group activities and scaffolded project work. The evaluation strategy was informed by theories of academic motivation, educational value within communities of practice and behaviour change. A simultaneous nested design was tested using a mixed methods survey with input from learners and teachers. 177 survey responses were analysed to quantify and compare self-rated impacts of teaching across different audiences. Qualitative data were inductively coded into themes that were categorised according to above theoretical frameworks. Participants felt that this was 'time well spent' and many described transformative impacts that guided their daily professional practice beyond learning about QI. We suggest that meaningful space is found within both undergraduate and postgraduate healthcare curricula for SusQI, as a way of engaging and motivating learners to contribute to the creation of a sustainable healthcare system.

Sustainable healthcare in medical education: survey of the student perspectives at a UK medical school.

BACKGROUND: It is now a General Medical Council requirement to incorporate education for sustainable healthcare (ESH) into medical curricula. To date, research has focussed on the perspectives of educators and which sustainable healthcare topics to include in teaching. Therefore, due to this gap in the literature, we have investigated the perspectives of medical students in the UK regarding current and future incorporation of ESH in medical education. METHODS: A survey was circulated to 851 clinical year medical students and students intercalating after completing at least one clinical year in a London University. The anonymous survey consisted of sections on the environmental impact, current teaching and future teaching of ESH. RESULTS: One hundred sixty-three students completed the survey. 93% of participants believed that climate change is a concern in current society, and only 1.8% thought they have been formally taught what sustainable healthcare is. No participants strongly agreed, and only 5 participants (3.1%) agreed, that they would feel confident in answering exam questions on this topic, with 89% agreeing that more ESH is needed. 60% believe that future teaching should be incorporated in both preclinical and clinical years, with 31% of participants preferring online modules as the method of teaching. CONCLUSION: Our study has stressed the lack of current sustainable healthcare teaching in the medical curriculum. There is student demand for ESH, however, uncertainty remains regarding who is best placed to facilitate ESH, how it should be delivered, and whether there is a gender discrepancy regarding sustainable healthcare importance, emphasising the need to close the gap between educational rhetoric and action.
