A cross-sectional study of the first two years of mandatory training for doctors participating in voluntary assisted dying.

OBJECTIVES: Voluntary assisted dying (VAD) was legalized in Victoria, Australia, in June 2019. Victoria was the first jurisdiction in the world to require doctors to undertake training before providing VAD. This study examines data from doctors who completed the mandatory training in the first 2 years of the VAD system's operation (up to 30 June 2021). It describes the doctors who are undertaking VAD training, their post-training attitudes toward VAD participation, and their experiences of the mandatory training. METHODS: Through the online training, doctors completed a short demographic survey and undertook formal assessment of knowledge (90% pass mark). They also were invited to complete an optional survey evaluating the training. RESULTS: In total, 289 doctors passed the training, most commonly males (56%) aged 36-65 years (82%) from an urban location (72%). Most were more than 10 years post fellowship (68%) and practising as general practitioners (51%) or medical oncologists (16%). The training most commonly took 6 h (range 2 h to over 9 h). Most doctors passed the assessment at the first (65%) or second (19%) attempt. Almost all participants (97%) found the training helpful or very helpful and most reported being confident or very confident in their knowledge (93%) and application (88%) of the VAD legislation. SIGNIFICANCE OF RESULTS: Doctors reported the training was helpful and improved their confidence in knowing the law and applying it in clinical practice. The profile of trained doctors (particularly their location and specialty) suggests continued growth of participating doctors is needed to facilitate patient access to VAD. It is important that this safeguard does not discourage doctors' participation.

Clinical supervision in general practice training: the interweaving of supervisor, trainee and patient entrustment with clinical oversight, patient safety and trainee learning.

Australian general practice trainees typically consult with patients from their first week of training, seeking in-consultation supervisory assistance only when not sufficiently confident to complete patient consultations independently. Trainee help-seeking plays a key role in supervisor oversight of trainee consultations. This study used focus groups and interviews with general practice supervisors to explore their approaches to trainee help-seeking and in-consultation supervision. Supervisor approaches are discussed under three themes: establishing a help-seeking culture; perceptions of in-consultation assistance required; and scripts for help provision. Within these themes, three interwoven entrustment processes were identified: supervisor entrustment; trainee self-entrustment; and 'patient entrustment' (patient confidence in the trainee's clinical management). Entrustment appears to develop rapidly, holistically and informally in general practice training, partly in response to workflow pressure and time constraints. Typical supervisor scripts and etiquette for help-provision involve indirect, soft correction strategies to build trainee self-entrustment. These scripts appear to be difficult to adapt appropriately to under-performing trainees. Importantly, supervisor scripts also promote patient entrustment, increasing the likelihood of patients returning to the trainee and training practice for subsequent review, which is a major mechanism for ensuring patient safety in general practice. Theories of entrustment in general practice training must account for the interplay between supervisor, trainee and patient entrustment processes, and work-related constraints. Gaps between entrustment as espoused in theory, and entrustment as enacted, may suggest limitations of entrustment theory when extended to the general practice context, and/or room for improvement in the oversight of trainee consultations in general practice training.

Development of Voluntary Assisted Dying Training in Victoria, Australia: A Model for Consideration.

BACKGROUND: Voluntary assisted dying was legalized in Victoria, Australia in June 2019, and was the first jurisdiction internationally to legislatively mandate training for doctors conducting eligibility assessments of patients. Mandatory training was designed as a safeguard to ensure compliance within the system, so that only eligible patients would gain access to voluntary assisted dying. OBJECTIVE: This article outlines the development of training mandated for doctors prior to undertaking eligibility assessments for voluntary assisted dying. The training addressed required legal knowledge, including doctors' roles, duties and legal protections, and also provided instruction on relevant clinical skills. DESIGN: Training design was based on 2 main principles: to comprehensively impart the legal duties imposed by the legislation; and to be readily accessible for busy doctors. The law was first mapped into a curriculum, and circulated to medical colleges, societies and professional organizations as well as international experts for feedback. The training was converted into an online e-learning format and tested at a focus group of doctors. RESULTS: The training comprises 9 modules including an assessment module. While the predominant focus of the modules is on law, they also contain some clinical components and links to further resources. Modules also contain videos, case studies and interactive exercises. The assessment consists of 30 questions, selected randomly from a question bank, with a pass mark of 90%. CONCLUSION: The Victorian legislatively-mandated voluntary assisted dying training provides standardized baseline knowledge to enhance the quality and consistency of decision-making by doctors. While further evaluation of this training is needed, it may provide a model for other jurisdictions considering making voluntary assisted dying lawful.

With a grain of salt? Supervisor credibility and other factors influencing trainee decisions to seek in-consultation assistance: a focus group study of Australian general practice trainees.

BACKGROUND: 'Ad hoc' help-seeking by trainees from their supervisors during trainee consultations is important for patient safety, and trainee professional development. We explored trainee objectives and activities in seeking supervisor assistance, and trainee perceptions of the outcomes of this help-seeking (including the utility of supervisor responses). METHODS: Focus groups with Australian general practice trainees were undertaken. All data was audio-recorded and transcribed, coded using in-vivo and descriptive codes, and analysed by the constant comparison of provisional interpretations and themes with the data. Findings are reported under the over-arching categories of help-seeking objectives, activities and outcomes. RESULTS: Early in their general practice placements trainees needed information about practice facilities, and the "complex maze" of local patient resources and referral preferences: some clinical presentations were also unfamiliar, and many trainees were unaccustomed to making patient management decisions. Subsequent help-seeking was often characterised informally as "having a chat" or "getting a second opinion" so as not to "miss anything" when trainees were "not 100% sure". Trainees emphasised the importance of being (and demonstrating that they were) clinically safe. Workflow constraints, and supervisory and doctor-patient relationships, had a powerful influence on trainee help-seeking activities. An etiquette for providing help in front of patients was described. Trainees assessed the credibility of supervisors based on their approach to risk and their clinical expertise in the relevant area. Several trainees reported reservations about their supervisor's advice on occasions. CONCLUSION: A trainee's subsequent help-seeking is strongly influenced by how their supervisor responds when their help is sought. Trainees prefer to seek help from credible supervisors who respond promptly and maintain trainee 'face' in front of patients. Trainees learn through help-seeking to make their own clinical decisions but may remain uncertain about professional and societal expectations, and curious about how other general practitioners practise. Trainees value opportunities throughout their training to observe expert general practice.

Factors associated with non-beneficial treatments in end of life hospital admissions: a multicentre retrospective cohort study in Australia.

OBJECTIVE: To quantitatively assess the factors associated with non-beneficial treatments (NBTs) in hospital admissions at the end of life. DESIGN: Retrospective multicentre cohort study. SETTING: Three large, metropolitan tertiary hospitals in Australia. PARTICIPANTS: 831 adult patients who died as inpatients following admission to the study hospitals over a 6-month period in 2012. MAIN OUTCOME MEASURES: Odds ratios (ORs) of NBT derived from logistic regression models. RESULTS: Overall, 103 (12.4%) admissions involved NBTs. Admissions that involved conflict within a patient's family (OR 8.9, 95% CI 4.1 to 18.9) or conflict within the medical team (OR 6.5, 95% CI 2.4 to 17.8) had the strongest associations with NBTs in the all subsets regression model. A positive association was observed in older patients, with each 10-year increment in age increasing the likelihood of NBT by approximately 50% (OR 1.5, 95% CI 1.2 to 1.9). There was also a statistically significant hospital effect. CONCLUSIONS: This paper presents the first statistical modelling results to assess the factors associated with NBT in hospital, beyond an intensive care setting. Our findings highlight potential areas for intervention to reduce the likelihood of NBTs.

Doctors' perceptions of how resource limitations relate to futility in end-of-life decision making: a qualitative analysis.

OBJECTIVE: To increase knowledge of how doctors perceive futile treatments and scarcity of resources at the end of life. In particular, their perceptions about whether and how resource limitations influence end-of-life decision making. This study builds on previous work that found some doctors include resource limitations in their understanding of the concept of futility. SETTING: Three tertiary hospitals in metropolitan Brisbane, Australia. DESIGN: Qualitative study using in-depth, semistructured, face-to-face interviews. Ninety-six doctors were interviewed in 11 medical specialties. Transcripts of the interviews were analysed using thematic analysis. RESULTS: Doctors' perceptions of whether resource limitations were relevant to their practice varied, and doctors were more comfortable with explicit rather than implicit rationing. Several doctors incorporated resource limitations into their definition of futility. For some, availability of resources was one factor of many in assessing futility, secondary to patient considerations, but a few doctors indicated that the concept of futility concealed rationing. Doctors experienced moral distress due to the resource implications of providing futile treatment and the lack of administrative supports for bedside rationing. CONCLUSIONS: Doctors' ability to distinguish between futility and rationing would be enhanced through regulatory support for explicit rationing and strategies to support doctors' role in rationing at the bedside. Medical policies should address the distinction between resource limitations and futility to promote legitimacy in end-of-life decision making.

Australian Policies on "Futile" or "Non-beneficial" Treatment at the End of Life: A Qualitative Content Analysis.

A challenge in end-of-life care is requests by patients or their substitute decision-makers for treatment that doctors consider is "futile" or "non-beneficial". Concerns that these concepts are uncertain and subjective have led to calls for medical policies to clarify terminology and to provide procedural solutions to prevent and address disputes. This article provides a comprehensive analysis of how Australian medical guidelines and policies on withholding or withdrawing potentially life-sustaining treatment address futility. It demonstrates that while the concept is found throughout medical policies and guidelines, the terminology employed is inconsistent. There is also variability in the extent of guidance given about unilateral decision-making and mechanisms for dispute resolution. This is problematic, given that the question of further treatment can often only be determined in relation to the individual patient's goals and values. We conclude by advocating for the development of a unified policy approach to futile or non-beneficial treatment in Australia.

Law as Clinical Evidence: A New ConstitutiveModel of Medical Education and Decision-Making.

Over several decades, ethics and law have been applied to medical education and practice in a way that reflects the continuation during the twentieth century of the strong distinction between facts and values. We explain the development of applied ethics and applied medical law and report selected results that reflect this applied model from an empirical project examining doctors' decisions on withdrawing/withholding treatment from patients who lack decision-making capacity. The model is critiqued, and an alternative "constitutive" model is supported on the basis that medicine, medical law, and medical ethics exemplify the inevitable entanglement of facts and values. The model requires that ethics and law be taught across the medical education curriculum and integrated with the basic and clinical sciences and that they be perceived as an integral component of medical evidence and practice. Law, in particular, would rank as equal in normative authority to the relevant clinical scientific "facts" of the case, with graduating doctors having as strong a basic command of each category as the other. The normalization of legal knowledge as part of the clinician's evidence base to be utilized in practice may provide adequate consolation for clinicians who may initially resent further perceived incursions on their traditional independence and discretion.

Australian doctors' knowledge of and compliance with the law relating to end-of-life decisions: implications for LGBTI patients.

In most developed countries, competent patients have the legal right to refuse any medical treatment; Advance Care Planning mechanisms extend this right to non-competent patients. However, some groups, including lesbian, gay, bisexual, transgender and intersex (LGBTI) people, risk their wishes not being respected if they lose capacity, more than others. Little is known about medical practitioners' knowledge of, or attitudes to, the law in this area, especially in relation to LGBTI people, or how the law influences their decision-making. An Australian postal survey explored knowledge and attitudes of medical specialists to legal issues relating to withdrawing/ withholding life-sustaining treatment from adults without capacity. One scenario (the focus of this paper) asked which of four plausible substitute decision-makers, including a same-sex partner, had the legal authority to make such decisions. The overall response rate was 32% (867/2702). Less than one-third of respondents correctly identified the same-sex partner as the legally authorised decision-maker. LGBTI people face multiple obstacles to having their end-of-life wishes respected. Where healthcare providers are also ignorant of the partner's legal right to make such decisions, the problem is compounded. Improved legal education for clinicians and promotion of educational resources for members of the LGBTI community is needed.

The need to exercise caution in accepting addiction as a reason for performing euthanasia.

The recent practice in Belgium and the Netherlands of accepting addiction as a reason for performing euthanasia raises important issues for the field of addiction and the practice of euthanasia. In this paper we outline some of these issues. We also argue that physicians making decisions about whether to accept requests for euthanasia from people with an allegedly untreatable addiction should consider two issues carefully. They should ensure that: (1) the person has the capacity to give free and informed consent to undergo euthanasia; and (2) their request is the outcome of a deliberative process in which all reasonable treatment options and harm reduction measures have been offered to and considered by the person.

Comparing doctors' legal compliance across three Australian states for decisions whether to withhold or withdraw life-sustaining medical treatment: does different law lead to different decisions?

BACKGROUND: Law purports to regulate end-of-life care but its role in decision-making by doctors is not clear. This paper, which is part of a three-year study into the role of law in medical practice at the end of life, investigates whether law affects doctors' decision-making. In particular, it considers whether the fact that the law differs across Australia's three largest states - New South Wales (NSW), Victoria and Queensland - leads to doctors making different decisions about withholding and withdrawing life-sustaining treatment from adults who lack capacity. METHODS: A cross-sectional postal survey of the seven specialties most likely to be involved in end-of-life care in the acute setting was conducted between 18 July 2012 and 31 January 2013. The sample comprised all medical specialists in emergency medicine, geriatric medicine, intensive care, medical oncology, palliative medicine, renal medicine and respiratory medicine on the AMPCo Direct database in those three Australian states. The survey measured medical specialists' level of legal compliance, and reasons for their decisions, concerning the withholding or withdrawal of life-sustaining treatment. Multivariable logistic regression was used to examine predictors of legal compliance. Linear regression was used to examine associations between the decision about life-sustaining treatment and the relevance of factors involved in making these decisions, as well as state differences in these associations. RESULTS: Response rate was 32% (867/2702). A majority of respondents in each state said that they would provide treatment in a hypothetical scenario, despite an advance directive refusing it: 72% in NSW and Queensland; 63% in Victoria. After applying differences in state law, 72% of Queensland doctors answered in accordance with local law, compared with 37% in Victoria and 28% in NSW (p < 0.001). Doctors reported broadly the same decision-making approach despite differences in local law. CONCLUSIONS: Law appears to play a limited role in medical decision-making at the end of life with doctors prioritising patient-related clinical and ethical considerations. Different legal frameworks in the three states examined did not lead to different decisions about providing treatment. More education is needed about law and its role in this area, particularly where law is inconsistent with traditional practice.

Incidence, duration and cost of futile treatment in end-of-life hospital admissions to three Australian public-sector tertiary hospitals: a retrospective multicentre cohort study.

OBJECTIVES: To estimate the incidence, duration and cost of futile treatment for end-of-life hospital admissions. DESIGN: Retrospective multicentre cohort study involving a clinical audit of hospital admissions. SETTING: Three Australian public-sector tertiary hospitals. PARTICIPANTS: Adult patients who died while admitted to one of the study hospitals over a 6-month period in 2012. MAIN OUTCOME MEASURES: Incidences of futile treatment among end-of-life admissions; length of stay in both ward and intensive care settings for the duration that patients received futile treatments; health system costs associated with futile treatments; monetary valuation of bed days associated with futile treatment. RESULTS: The incidence rate of futile treatment in end-of-life admissions was 12.1% across the three study hospitals (range 6.0%-19.6%). For admissions involving futile treatment, the mean length of stay following the onset of futile treatment was 15 days, with 5.25 of these days in the intensive care unit. The cost associated with futile bed days was estimated to be $AA12.4 million for the three study hospitals using health system costs, and $A988 000 when using a decision maker's willingness to pay for bed days. This was extrapolated to an annual national health system cost of $A153.1 million and a decision maker's willingness to pay of $A12.3 million. CONCLUSIONS: The incidence rate and cost of futile treatment in end-of-life admissions varied between hospitals. The overall impact was substantial in terms of both the bed days and cost incurred. An increased awareness of these economic costs may generate support for interventions designed to reduce futile treatments. We did not include emotional hardship or pain and suffering, which represent additional costs.

Changes in LXR signaling influence early-pregnancy lipogenesis and protect against dysregulated fetoplacental lipid homeostasis.

Human pregnancy is associated with enhanced de novo lipogenesis in the early stages followed by hyperlipidemia during advanced gestation. Liver X receptors (LXRs) are oxysterol-activated nuclear receptors that stimulate de novo lipogenesis and also promote the efflux of cholesterol from extrahepatic tissues followed by its transport back to the liver for biliary excretion. Although LXR is recognized as a master regulator of triglyceride and cholesterol homeostasis, it is unknown whether it facilitates the gestational adaptations in lipid metabolism. To address this question, biochemical profiling, protein quantification, and gene expression studies were used, and gestational metabolic changes in T0901317-treated wild-type mice and Lxrab-/- mutants were investigated. Here, we show that altered LXR signaling contributes to the enhanced lipogenesis in early pregnancy by increasing the expression of hepatic Fas and stearoyl-CoA desaturase 1 (Scd1). Both the pharmacological activation of LXR with T0901317 and the genetic ablation of its two isoforms disrupted the increase in hepatic fatty acid biosynthesis and the development of hypertriglyceridemia during early gestation. We also demonstrate that absence of LXR enhances maternal white adipose tissue lipolysis, causing abnormal accumulation of triglycerides, cholesterol, and free fatty acids in the fetal liver. Together, these data identify LXR as an important factor in early-pregnancy lipogenesis that is also necessary to protect against abnormalities in fetoplacental lipid homeostasis.

Gestational disruptions in metabolic rhythmicity of the liver, muscle, and placenta affect fetal size.

Maternal metabolic adaptations are essential for successful pregnancy outcomes. We investigated how metabolic gestational processes are coordinated, whether there is a functional link with internal clocks, and whether disruptions are related to metabolic abnormalities in pregnancy, by studying day/night metabolic pathways in murine models and samples from pregnant women with normally grown and large-for-gestational age infants. In early mouse pregnancy, expression of hepatic lipogenic genes was up-regulated and uncoupled from the hepatic clock. In late mouse pregnancy, rhythmicity of energy metabolism-related genes in the muscle followed the patterns of internal clock genes in this tissue, and coincided with enhanced lipid transporter expression in the fetoplacental unit. Diurnal triglyceride patterns were disrupted in human placentas from pregnancies with large-for-gestational age infants and this overlapped with an increase in BMAL1 expression. Metabolic adaptations in early pregnancy are uncoupled from the circadian clock, whereas in late pregnancy, energy availability is mediated by coordinated muscle-placenta metabolic adjustments linked to internal clocks. Placental triglyceride oscillations in the third trimester of human pregnancy are lost in large-for-gestational age infants and may be regulated by BMAL1. In summary, disruptions in metabolic and circadian rhythmicity are associated with increased fetal size, with implications for the pathogenesis of macrosomia.-Papacleovoulou, G., Nikolova, V., Oduwole, O., Chambers, J., Vazquez-Lopez, M., Jansen, E., Nicolaides, K., Parker, M., Williamson, C. Gestational disruptions in metabolic rhythmicity of the liver, muscle, and placenta affect fetal size.

The role of law in decisions to withhold and withdraw life-sustaining treatment from adults who lack capacity: a cross-sectional study.

OBJECTIVES: To determine the role played by law in medical specialists' decision-making about withholding and withdrawing life-sustaining treatment from adults who lack capacity, and the extent to which legal knowledge affects whether law is followed. DESIGN: Cross-sectional postal survey of medical specialists. SETTING: The two largest Australian states by population. PARTICIPANTS: 649 medical specialists from seven specialties most likely to be involved in end-of-life decision-making in the acute setting. MAIN OUTCOME MEASURES: Compliance with law and the impact of legal knowledge on compliance. RESULTS: 649 medical specialists (of 2104 potential participants) completed the survey (response rate 31%). Responses to a hypothetical scenario found a potential low rate of legal compliance, 32% (95% CI 28% to 36%). Knowledge of the law and legal compliance were associated: within compliers, 86% (95% CI 83% to 91%) had specific knowledge of the relevant aspect of the law, compared with 60% (95% CI 55% to 65%) within non-compliers. However, the reasons medical specialists gave for making decisions did not vary according to legal knowledge. CONCLUSIONS: Medical specialists prioritise patient-related clinical factors over law when confronted with a scenario where legal compliance is inconsistent with what they believe is clinically indicated. Although legally knowledgeable specialists were more likely to comply with the law, compliance in the scenario was not motivated by an intention to follow law. Ethical considerations (which are different from, but often align with, law) are suggested as a more important influence in clinical decision-making. More education and training of doctors is needed to demonstrate the role, relevance and utility of law in end-of-life care.

The nuclear cofactor receptor interacting protein-140 (RIP140) regulates the expression of genes involved in Aß generation.

The receptor interacting protein-140 (RIP140) is a cofactor for several nuclear receptors and has been involved in the regulation of metabolic and inflammatory genes. We hypothesize that RIP140 may also affect Aß generation because it modulates the activity of transcription factors previously implicated in amyloid precursor protein (APP) processing, such as peroxisome proliferator-activated receptor-γ (PPARγ). We found that the levels of RIP140 are reduced in Alzheimer's disease (AD) postmortem brains compared with healthy controls. In addition, in situ hybridization experiments revealed that RIP140 expression is enriched in the same brain areas involved in AD pathology, such as cortex and hippocampus. Furthermore, we provide evidence using cell lines and genetically modified mice that RIP140 is able to modulate the transcription of certain genes involved in AD pathology, such as ß-APP cleaving enzyme (BACE1) and GSK3. Consequently, we found that RIP140 overexpression reduced the generation of Aß in a neuroblastoma cell line by decreasing the transcription of ß-APP cleaving enzyme via a PPARγ-dependent mechanism. The results of this study therefore provide molecular insights into common signaling pathways linking metabolic disease with AD.

Knowledge of the law about withholding or withdrawing life-sustaining treatment by intensivists and other specialists.

OBJECTIVE: Decisions about withholding or withdrawing life-sustaining treatment (WWLST) from adults who lack capacity are an integral part of intensive care (IC) practice. We compare the knowledge, attitudes and practice of intensivists in relation to the law about WWLST with six other specialties most often involved in end-of-life care. DESIGN, SETTING AND PARTICIPANTS: We used a cross-sectional postal survey of medical specialists in the three most populous Australian states, and analysed responses from 867 medical specialists from the seven specialties most likely to be involved in WWLST decisions in the acute-care setting (emergency, geriatric, palliative, renal and respiratory medicine, medical oncology and IC). MAIN OUTCOME MEASURES: Attitudes to, and knowledge and practice of, the law relating to end-of-life care. RESULTS: Of 2702 surveys sent to eligible practitioners, 867 completed questionnaires were returned. There was an overall response rate of 32% and an IC response rate also of 32% (125/388). Intensivists performed better than average in legal knowledge but important knowledge gaps remain. Intensivists had a more negative attitude to the role of law in this area than other specialty groups but reported being seen as a leading source of information about legal issues by other medical specialists and nurses. Intensivists also reported being the specialists most frequently making decisions about end-of-life treatment. CONCLUSIONS: Improved legal knowledge and open engagement with the law can help manage the risk of harm to patients and protect intensivists from liability. IC guidelines and continuing professional development are important strategies to address these issues.
