Phase 0 Study of Vandetanib-Eluting Radiopaque Embolics as a Preoperative Embolization Treatment in Patients with Resectable Liver Malignancies.

PURPOSE: To assess the safety and tolerability of a vandetanib-eluting radiopaque embolic (BTG-002814) for transarterial chemoembolization (TACE) in patients with resectable liver malignancies. MATERIALS AND METHODS: The VEROnA clinical trial was a first-in-human, phase 0, single-arm, window-of-opportunity study. Eligible patients were aged ≥18 years and had resectable hepatocellular carcinoma (HCC) (Child-Pugh A) or metastatic colorectal cancer (mCRC). Patients received 1 mL of BTG-002814 transarterially (containing 100 mg of vandetanib) 7-21 days prior to surgery. The primary objectives were to establish the safety and tolerability of BTG-002814 and determine the concentrations of vandetanib and the N-desmethyl vandetanib metabolite in the plasma and resected liver after treatment. Biomarker studies included circulating proangiogenic factors, perfusion computed tomography, and dynamic contrast-enhanced magnetic resonance imaging. RESULTS: Eight patients were enrolled: 2 with HCC and 6 with mCRC. There was 1 grade 3 adverse event (AE) before surgery and 18 after surgery; 6 AEs were deemed to be related to BTG-002814. Surgical resection was not delayed. Vandetanib was present in the plasma of all patients 12 days after treatment, with a mean maximum concentration of 24.3 ng/mL (standard deviation ± 13.94 ng/mL), and in resected liver tissue up to 32 days after treatment (441-404,000 ng/g). The median percentage of tumor necrosis was 92.5% (range, 5%-100%). There were no significant changes in perfusion imaging parameters after TACE. CONCLUSIONS: BTG-002814 has an acceptable safety profile in patients before surgery. The presence of vandetanib in the tumor specimens up to 32 days after treatment suggests sustained anticancer activity, while the low vandetanib levels in the plasma suggest minimal release into the systemic circulation. Further evaluation of this TACE combination is warranted in dose-finding and efficacy studies.

Implementing the Smile4life intervention for people experiencing homelessness: a path analytical evaluation.

BACKGROUND: People experiencing homelessness have high levels of dental decay, oral cancer and poor oral health-related quality of life. The Scottish Government sought to address these issues by developing a national oral health improvement programme for people experiencing homelessness, named Smile4life. The aim was to investigate implementation behaviours and the role of work-related beliefs upon the delivery of the Smile4life programme across NHS Board areas in Scotland. METHODS: Non-probability convenience sampling, supplemented by snowball sampling, was used to recruit practitioners working across the homelessness sector. The overall evaluation of the implementation of the Smile4life programme was theoretically informed by the Behaviour Change Wheel. The questionnaire was informed by the Theoretical Domains Framework and was divided into three sections, demography and Smile4life Awareness; Smile4life Activities; and Smile4life work-related beliefs. A psychometric assessment was used to develop Smile4life Awareness, Smile4life Activities, Ability to Deliver and Positive Beliefs and Outcomes subscales. The data were subjected to K-R20, exploratory factor analysis, Cronbach's alpha, t-tests, ANOVA, Pearson's correlation analysis and a multivariate path analysis. RESULTS: One hundred participants completed the questionnaire. The majority were female (79%) and worked in NHS Boards across Scotland (55%). Implementation behaviour, constructed from the Delivering Smile4life scale and the summated Smile4life activities variable, was predicted using a linear model a latent variable. The independent variables were two raw variables Positive Beliefs and Outcomes, and Ability to deliver Smile4life. Results showed relatively good model fit (chi-square (1.96; p > 0.15), SRMR (< 0.08) and R2 (0.62) values). Positive and highly significant loadings were found describing the Implementation Behaviour latent variable (0.87 and 0.56). The two independent variables were associated (p < 0.05) with Implementation Behaviour. CONCLUSIONS: Work-related factors, such as positive beliefs and outcomes and ability to deliver are required for implementation behaviours associated with the delivery of the Smile4life programme. Future work should include training centred on the specific needs of those involved in the homelessness sector and the development of accessible training resources, thereby promoting implementation behaviours to assist the progression and sustainability of the Smile4life programme.

How rapid advances in imaging are defining the future of precision radiation oncology.

Imaging has an essential role in the planning and delivery of radiotherapy. Recent advances in imaging have led to the development of advanced radiotherapy techniques-including image-guided radiotherapy, intensity-modulated radiotherapy, stereotactic body radiotherapy and proton beam therapy. The optimal use of imaging might enable higher doses of radiation to be delivered to the tumour, while sparing normal surrounding tissues. In this article, we review how the integration of existing and novel forms of computed tomography, magnetic resonance imaging and positron emission tomography have transformed tumour delineation in the radiotherapy planning process, and how these advances have the potential to allow a more individualised approach to the cancer therapy. Recent data suggest that imaging biomarkers that assess underlying tumour heterogeneity can identify areas within a tumour that are at higher risk of radio-resistance, and therefore potentially allow for biologically focussed dose escalation. The rapidly evolving concept of adaptive radiotherapy, including artificial intelligence, requires imaging during treatment to be used to modify radiotherapy on a daily basis. These advances have the potential to improve clinical outcomes and reduce radiation-related long-term toxicities. We outline how recent technological advances in both imaging and radiotherapy delivery can be combined to shape the future of precision radiation oncology.

Exploring the benefits of Smile4life training: Findings from a pilot study.

Smile4life is Scotland's national oral health improvement programme for people experiencing homelessness. Following an oral health and psychosocial needs assessment of 853 homeless people across Scotland, the Smile4life intervention was developed and rolled out across all NHS boards. Dental health and health and social care practitioners were invited to attend a training event at the launch of the Smile4life: Guide for Trainers - a training guide for practitioners working with homeless people. This paper presents results from HoPSCOTCH, a pilot study that took place in four NHS boards to examine the benefits of training for practitioners regarding their awareness of homelessness and the oral health needs of homeless people. Dental health (baseline: 10; follow-up: 8) and health and social care practitioners (baseline: 13; follow-up: 12) completed questionnaires about their knowledge, attitudes and behaviours. The results showed that there were increases in practitioner knowledge, confidence and motivation to help service users access dental care, to provide oral health education and to use motivational interviewing. The authors recommend that future training for practitioners who work with homeless people should include communication skills and advice on how to deliver tailored interventions, with the aim of strengthening practitioners' confidence and motivation to deliver the Smile4life intervention.

Why are people afraid of the dentist? Observations and explanations.

OBJECTIVE: The aim of this review was to explore the peer-reviewed literature to answer the question: 'Why are people afraid of the dentist?' METHOD: Relevant literature was identified by searching the following on-line databases: PubMed, PsycInfo, the Cochrane Library and Google Scholar. Publications were extracted if they explored the causes and consequences of dental fear, dental anxiety or dental phobia. RESULTS: The research evidence suggests that the causes of dental fear, dental anxiety or dental phobia are related to exogenous factors such as direct learning from traumatic experiences, vicarious learning through significant others and the media, and endogenous factors such as inheritance and personality traits. Each individual aetiological factor is supported by the evidence provided. CONCLUSIONS: The evidence suggests that the aetiology of dental fear, anxiety or phobia is complex and multifactorial. The findings show that there are clear practical implications indicated by the existing research in this area: a better understanding of dental fear, anxiety and phobia may prevent treatment avoidance.

Sustainable oral healthcare: what is it and how do we achieve it?

In recent years, there has been an increase in interest in what environmental sustainability means for healthcare, including oral health and dentistry. To help facilitate discussions among key stakeholders in this area, the Scottish Dental Clinical Effectiveness Programme held a workshop in November 2022. The purpose of this workshop was to explore current thinking on the subject of sustainability as it relates to oral health and to help stakeholders identify how to engage with the sustainability agenda. This paper presents an overview of the presentations and discussions from the workshop and highlights potential avenues for future work and collaboration.

The practices and beliefs of dental professionals regarding the management of patients taking anticoagulant and antiplatelet drugs.

AIM: This study aimed to inform the implementation of the updated Scottish Dental Clinical Effectiveness Programme (SDCEP) guidance, 'Management of Dental Patients taking Anticoagulant or Antiplatelet Drugs', and to determine training needs by investigating dental professionals' current practice and beliefs regarding management of patients taking these medications. METHODS: Dental professionals were recruited via the NHS Education for Scotland Portal. The online questionnaire collected demographic information, data on current practice and information about beliefs regarding behaviours related to the management of patients on anticoagulant or antiplatelet medication. Quantitative data were analysed using SPSS and subjected to frequency calculations, t-tests, one-way ANOVA and linear regression. Qualitative data were collected via free text boxes and analysed using thematic analysis. RESULTS: One hundred and fifty-seven participants responded to the questionnaire. The majority of respondents stated they were aware of the guidance and always based their practice on it. The majority of respondents always assessed the patient's individual bleeding risk prior to dental procedures. Most respondents felt that they did not know how to appropriately manage patients taking low doses of low molecular weight heparins (LMWH), and only 38% of respondents always followed SDCEP guidance about direct oral anticoagulants (DOAC) medication and procedures with a low associated risk of bleeding. DISCUSSION: This study demonstrates a need for further educational support surrounding LMWHs and management of patients on DOAC medication. Time and remuneration represent barriers to guidance implementation in primary care. CONCLUSION: There is good awareness and adherence to the guidance in primary care settings, however training needs were identified to support implementation.

Exploring the engagement behaviours of Smile4life practitioners: lessons from an evaluation of the national oral health improvement programme for people experiencing homelessness in Scotland.

Introduction: Smile4life is Scotland's national oral health improvement programme for people experiencing homelessness, aimed at reducing oral health inequalities experienced by this population. This study forms part of an evaluation of how the Smile4life intervention was being implemented within Scottish NHS Boards. The aim was to investigate the influence of the Smile4life intervention upon the engagement behaviours of Smile4life practitioners. Methods: Focus groups were conducted with Smile4life practitioners, to provide an insight into how the Smile4life intervention affected their skills, attitudes and experiences while interacting with people experiencing homelessness and their services providers. A purposive sample of oral health practitioners, including dental health support workers, oral health promoters/educators, and oral health improvement coordinators working in three NHS Boards were invited to take part. One focus group was conducted in each of the three NHS Boards. The focus groups were audio-recorded and transcribed. The COM-B model of behaviour was used as a framework for analysis. Results: Eleven Smile4life practitioners took part in the focus groups. All had first-hand experience of working with the Smile4life intervention. The average focus group length was 67 min. Working on the Smile4life intervention provided the Smile4life practitioners with: (i) the capability (physical and psychological), (ii) the opportunity (to establish methods of communication and relationships with service providers and service users) and (iii) the motivation to engage with Third Sector homelessness services and service users, by reflecting upon their positive and negative experiences delivering the intervention. Enablers and barriers to this engagement were identified according to each of the COM-B categories. Enablers included: practitioners' sense of responsibility, reflecting on positive past experiences and success stories with service users. Barriers included: lack of resources, negative past experiences and poor relationships between Smile4life practitioners and Third Sector staff. Conclusion: The Smile4life programme promoted capability, provided opportunities and increased motivation in those practitioners who cross disciplinary boundaries to implement the Smile4life intervention, which can be conceptualised as "boundary spanning". Practitioners who were found to be boundary spanners often had a positive mindset and proactive attitude towards the creation of strategies to overcome the challenges of implementation by bridging the gaps between the NHS and the Third Sector, and between oral health and homelessness, operating across differing fields to achieve their aims.

A qualitative analysis of dental professionals' beliefs and concerns about providing aerosol generating procedures early in the COVID-19 pandemic.

INTRODUCTION: In response to the COVID-19 pandemic, the Scottish Dental Clinical Effectiveness Programme (SDCEP) initiated a rapid review of the evidence related to the generation and mitigation of aerosols in dental practice. To support this review, a survey was distributed to better understand the provision of aerosol generating procedures (AGPs) in dentistry. METHODS: An online questionnaire was distributed to dental professionals asking about their current practice and beliefs about AGPs. Data were analysed using qualitative content analysis. RESULTS: Analysis revealed confusion and uncertainty regarding mitigation of AGPs. There was also frustration and scepticism over the risk of SARS-COV-2 transmission within dental settings, the evidence underpinning the restrictions and the leadership and guidance being provided, as well as concern over financial implications and patient and staff safety. DISCUSSION: The frustration and concerns expressed by respondents mirrored findings from other recent studies and suggest there is a need for reflection within the profession so that lessons can be learned to better support staff and patients. CONCLUSION: Understanding the profession's views about AGP provision contributed to the SDCEP rapid review and provides insights to help inform policymakers and leaders in anticipation not only of future pandemics but in considering the success of any large scale and/or rapid organisational change.

Longitudinal online diaries with dental practitioners and dental care professionals during the COVID-19 pandemic: A trajectory analysis.

Introduction: The COVID-19 pandemic resulted in a series of significant changes and adjustments within dentistry, as dental professionals dealt with temporary closures of dental practices, increased use of personal protective equipment, a reduction of clinical procedures, and extensions to training programmes. Recent research has illustrated the impact of the pandemic on the dental profession, indicating that many dental professionals felt emotionally exhausted and experienced significant uncertainty and anxiety. This qualitative study aimed to understand how these experiences and emotions changed over the course of six months, in dental trainees and primary dental care staff in Scotland. Methods: A longitudinal diary study was conducted (June-December 2020) with dental trainees and primary dental care staff. The diary asked respondents to answer three questions related to their emotional exhaustion, on a weekly basis. There was also an open question asking respondents to describe any significant issues or concerns they had experienced during the preceding week because of the impact of the COVID-19 pandemic on their work or training. This qualitative data was explored using a trajectory analysis approach to determine specifically changes over time. Results: The trajectory analysis revealed several key concerns prevalent amongst respondents, and how they fluctuated over the six months. Concerns included: the impact of the pandemic on respondents' future careers and on dentistry more generally; adapting to new working environments; the impact on their patients' dental treatment and oral health; the impact on their health and wellbeing; financial considerations and adjusting to new safety measures as part of the remobilization of dental services. Discussion: In the second half of 2020, as the UK was adjusting to the introduction of new COVID-19 safety measures in everyday life, the dental profession were grappling with significant changes to their working environment, including PPE, redeployment, use of aerosol generating procedures (AGPs), and timelines for re-opening practices. This longitudinal diary study has shown some parts of the dental profession in Scotland expressed very varied and personal concerns and anxieties related to COVID-19. Respondents' candor in their diary entries revealed explicit, frequent and high levels of uncertainty and worry related to their training and career. Collectively, the data corpus highlighted the emotional toll these anxieties have taken on the dental professions in Scotland. Conclusion: These findings demonstrate the need for (a) increased provision of mental health and wellbeing support services for dental staff and (b) the study of the linkage between organization of pandemic management to the working practices of staff delivering services. Interventions, at various levels, should take into consideration the fluctuating nature of dental professionals' concerns and anxieties over time, to address both immediate and longer-term issues.

Identity Development in Disorientating Times: the Experiences of Medical Students During COVID-19.

Introduction: Professional identity development is a central aim of medical education, which has been disrupted during COVID-19. Yet, no research has qualitatively explored COVID-19's impact across institutions or countries on medical students' identities. Kegan proposes a cognitive model of identity development, where 'disorientating dilemmas' prompt student development. Given the potential of COVID-related disruption to generate disorientating dilemmas, the authors investigated the ways in which COVID-19 influenced students' identity development. Methods: The authors conducted an international qualitative study with second year medical students from Imperial College London, and third year students from Melbourne Medical School. Six focus groups occurred 2020-2021, with three to six students per group. Authors analysed data using reflexive thematic analysis, applying Kegan's model as a sensitising theoretical lens. Results: COVID-19 has resulted in a loss of clinical exposure, loss of professional relationships, and a shift in public perception of physicians. Loss of exposure to clinical practice removed the external validation from patients and seniors many students depended on for identity development. Students' experiences encouraged them to assume the responsibilities of the profession and the communities they served, in the face of conflicting demands and risk. Acknowledging and actioning this responsibility facilitated identity development as a socially responsible advocate. Conclusions: Educators should consider adapting medical education to support students through Kegan's stages of development. Measures to foster relationships between students, patients, and staff are likely necessary. Formal curricula provisions, such as spaces for reflection and opportunities for social responsibility, may aid students in resolving the conflict many have recently experienced.

Radiopaque drug-eluting embolisation beads as fiducial markers for stereotactic liver radiotherapy.

OBJECTIVE: To determine the feasibility of using radiopaque (RO) beads as direct tumour surrogates for image-guided radiotherapy (IGRT) in patients with liver tumours after transarterial chemoembolisation (TACE). METHODS: A novel vandetanib-eluting RO bead was delivered via TACE as part of a first-in-human clinical trial in patients with either hepatocellular carcinoma or liver metastases from colorectal cancer. Following TACE, patients underwent simulated radiotherapy imaging with four-dimensional computed tomography (4D-CT) and cone-beam CT (CBCT) imaging. RO beads were contoured using automated thresholding, and feasibility of matching between the simulated radiotherapy planning dataset (AVE-IP image from 4D data) and CBCT scans assessed. Additional kV, MV, helical CT and CBCT images of RO beads were obtained using an in-house phantom. Stability of RO bead position was assessed by comparing 4D-CT imaging to CT scans taken 6-20 days following TACE. RESULTS: Eight patients were treated and 4D-CT and CBCT images acquired. RO beads were visible on 4D-CT and CBCT images in all cases and matching successfully performed. Differences in centre of mass of RO beads between CBCT and simulated radiotherapy planning scans (AVE-IP dataset) were 2.0 mm mediolaterally, 1.7 mm anteroposteriorally and 3.5 mm craniocaudally. RO beads in the phantom were visible on all imaging modalities assessed. RO bead position remained stable up to 29 days post TACE. CONCLUSION: RO beads are visible on IGRT imaging modalities, showing minimal artefact. They can be used for on-set matching with CBCT and remain stable over time. ADVANCES IN KNOWLEDGE: The role of RO beads as fiducial markers for stereotactic liver radiotherapy is feasible and warrants further exploration as a combination therapy approach.

Exploring adolescent and clinician perspectives on Australia.

Adolescence is often a time when risk-taking behaviours emerge and attendance at primary health care is low. School-based health services can serve to improve access to health care. Clinicians play a key role in improving adolescents' health literacy and capacity to make informed care decisions. Australia's national digital health record, My Health Record (MHR), has posed significant challenges for both clinicians and adolescents in understanding impacts on patient privacy. Guidance is required on how best to communicate about MHR to adolescents. This exploratory qualitative study aims to examine adolescents' understanding of MHR, clinicians' knowledge of MHR and their use of MHR with adolescents. Focus groups with students, school health and well-being staff and semistructured interviews with GPs and nurses were undertaken in one regional and one urban secondary school-based health service in Victoria. Transcripts from audio recorded sessions were examined using thematic analysis. Resulting themes include minimal understanding and use of MHR, privacy and security concerns, possible benefits of MHR and convenience. The results suggest opportunities to address gaps in understanding and to learn from adolescents' preferences for digital health literacy education. This will support primary care clinicians to provide best-practice health care for adolescents.

An evaluation of the implementation of quality improvement (QI) in primary care dentistry: a multi-method approach.

OBJECTIVES: Ensuring that healthcare is patient-centred, safe and harm free is the cornerstone of the NHS. The Scottish Patient Safety Programme (SPSP) is a national initiative to support the provision of safe, high-quality care. SPSP promotes a coordinated approach to quality improvement (QI) in primary care by providing evidence-based methods, such as the Institute for Healthcare Improvement's Breakthrough Series Collaborative methodology. These methods are relatively untested within dentistry. The aim of this study was to evaluate the impact to inform the development and implementation of improvement collaboratives as a means for QI in primary care dentistry. DESIGN: A multimethod study underpinned by the Theoretical Domains Framework and the Kirkpatrick model. Quantitative data were collected using baseline and follow-up questionnaires, designed to explore beliefs and behaviours towards improving quality in practice. Qualitative data were gathered using interviews with dental team members and practice-based case studies. RESULTS: One hundred and eleven dental team members completed the baseline questionnaire. Follow-up questionnaires were returned by 79 team members. Twelve practices, including two case studies, participated in evaluation interviews. Findings identified positive beliefs and increased knowledge and skills towards QI, as well as increased confidence about using QI methodologies in practice. Barriers included time, poor patient and team engagement, communication and leadership. Facilitators included team working, clear roles, strong leadership, training, peer support and visible benefits. Participants' knowledge and skills were identified as an area for improvement. CONCLUSIONS: Findings demonstrate increased knowledge, skills and confidence in relation to QI methodology and highlight areas for improvement. This is an example of partnership working between the Scottish Government and NHSScotland towards a shared ambition to provide safe care to every patient. More work is required to evaluate the sustainability and transferability of improvement collaboratives as a means for QI in dentistry and wider primary care.

Exploring the Effect of the COVID-19 Pandemic on the Dental Team: Preparedness, Psychological Impacts and Emotional Reactions.

Background: The COVID-19 pandemic has placed increased demands on clinical staff in primary dental care due to a variety of uncertainties. Current reports on staff responses have tended to be brief enquiries without some theoretical explanation supported by developed measurement systems. Aim: To investigate features of health and well-being as an outcome of the uncertainties surrounding COVID-19 for dentists and dental health professionals in primary dental care and for those in training. In addition, the study examined the well-being indices with reference to normative values. Finally a theoretical model was explored to explain depressive symptoms and investigate its generalisability across dentists and dental health professionals in primary dental care and those in postgraduate training. Methods: A cross-sectional survey of dental trainees and primary dental care staff in Scotland was conducted in June to October 2020. Assessment was through "Portal," an online tool used for course bookings/management administered by NHS Education for Scotland. A non-probability convenience sample was employed to recruit participants. The questionnaire consisted of four multi-item scales including: preparedness (14 items of the DPPPS), burnout (the 9 item emotional exhaustion subscale and 5 items of the depersonalisation subscale of the MBI), the 22 item Impact of Event Scale-Revised, and depressive symptomatology using the Patient Health Questionnaire-2. Analysis was performed to compare the levels of these assessments between trainees and primary dental care staff and a theoretically based path model to explain depressive symptomology, utilising structural equation modelling. Results: Approximately, 27% of all 329 respondents reported significant depressive symptomology and 55% of primary care staff rated themselves as emotionally exhausted. Primary care staff (n = 218) felt less prepared for managing their health, coping with uncertainty and financial insecurity compared with their trainee (n = 111) counterparts (all p's < 0.05). Depressive symptomology was rated higher than reported community samples (p < 0.05) The overall fit of the raw data applied to the theoretical model confirmed that preparedness (negative association) and trauma associated with COVID-19 (positive association) were significant factors predicting lowered mood (chi-square = 46.7, df = 21, p = 0.001; CFI = 0.98, RMSEA = 0.06, SRMR = 0.03). Burnout was indirectly implicated and a major path from trauma to burnout was found to be significant in primary care staff but absent in trainees (p < 0.002). Conclusion: These initial findings demonstrate the possible benefit of resourcing staff support and interventions to assist dental staff to prepare during periods of high uncertainty resulting from the recent COVID-19 pandemic.

Uncertainty and Fears Around Sustainability: A Qualitative Exploration of the Emotional Reactions of Dental Practitioners and Dental Care Professionals During COVID-19.

INTRODUCTION: Recent cross-sectional surveys have shown the detrimental impact of COVID-19 on the health and well-being of dental practitioners and dental care professionals. This qualitative study complements the growing quantitative evidence base with an in-depth exploration of the lived experiences of those working in primary care dental teams in Scotland. METHODS: Focus groups were carried out with primary care dental team members and trainees between July and October 2020. Olsen's tripartite framework of health service sustainability was operationalised to explore how participants experienced uncertainty and their attempts to sustain dental services. RESULTS: Analysis revealed significant concerns surrounding the sustainability of dental services and dental training programmes as a consequence of the emergency level response to the pandemic. Restrictions on dentistry were seen to be severely impeding desirable clinical outcomes, particularly for the most vulnerable groups. Participants experienced being unable to deliver high quality care to their patients as both confusing and distressing. The capability of the dental health care system to meet a growing backlog of dental need and manage this effectively in a pandemic era was called in to serious question. Ongoing uncertainties were affecting how participants were thinking about their professional futures, with stress about income and employment, along with heightened experiences of professional isolation during the pandemic, resulting in some looking at possibilities for retraining or even considering leaving their profession altogether. DISCUSSION: The impact of the pandemic has produced considerable uncertainty regarding the sustainability of dental services in the medium to longer term. It has also served to expose the uncertainties practitioners grapple with routinely as they attempt to sustain their NHS dental service delivery. CONCLUSION: This study brings in to sharp focus the diversity of challenges, confusions and uncertainties experienced by dental practitioners and dental care professionals during the COVID-19 pandemic and the need for suitable and ongoing measures to be put in place to support their mental well-being.

General practice in the era of planetary health: Responding to the climate health emergency.

BACKGROUND: It has been a decade since a landmark Lancet publication declared that 'climate change is the biggest global health threat of the 21st century'. Since then, Australia has experienced unprecedented warming related to climate change and an associated increase in the frequency and intensity of extreme weather events, including heatwaves, droughts, storms, bushfires and air pollution. These events have had major impacts on community physical and mental health. OBJECTIVE: The aim of this article is to describe the health impacts of climate change and the role of general practitioners (GPs) in responding to these impacts. DISCUSSION: While the clinical skills that underpin general practice have not changed, the environmental and planetary context has shifted. A 'planetary health' approach is required. Climate change should now be considered a health emergency. GPs have a critical role in mitigation and adaptation. Responding to climate change aligns with principles of preventive health and can produce 'co-benefits' for individual and population health.

Engaging vocational dental practitioners in care of the dependent elderly: findings from a pilot project.

Introduction A pilot project was developed whereby vocational dental practitioners (VDPs) became involved in the Caring for Smiles programme, visiting care homes and observing staff training.Aim The project aimed to explore VDPs' views and experiences of delivering oral healthcare in the care home environment.Method Qualitative data were collected via an online questionnaire and reflective logs. The data were analysed using thematic analysis to extract emerging themes.Results Six themes emerged from the data, demonstrating that the VDPs had become aware of the general health and oral health needs of the care home population, and their role as dentists in the provision of oral care. The VDPs also had an increased awareness of Caring for Smiles.Discussion The VDPs benefited from participation in the pilot; it raised their awareness but also exposed them to an environment with which many were unfamiliar. Some VDPs expressed an interest in providing oral care in care homes in the future and discussed the need for domiciliary care.Conclusion The participating VDPs gained a level of experience and familiarity with older patients, Caring for Smiles and the care home environment that may improve the care they provide to their patients.
