Determination of Brain Death/Death by Neurologic Criteria: The World Brain Death Project.

IMPORTANCE: There are inconsistencies in concept, criteria, practice, and documentation of brain death/death by neurologic criteria (BD/DNC) both internationally and within countries. OBJECTIVE: To formulate a consensus statement of recommendations on determination of BD/DNC based on review of the literature and expert opinion of a large multidisciplinary, international panel. PROCESS: Relevant international professional societies were recruited to develop recommendations regarding determination of BD/DNC. Literature searches of the Cochrane, Embase, and MEDLINE databases included January 1, 1992, through April 2020 identified pertinent articles for review. Because of the lack of high-quality data from randomized clinical trials or large observational studies, recommendations were formulated based on consensus of contributors and medical societies that represented relevant disciplines, including critical care, neurology, and neurosurgery. EVIDENCE SYNTHESIS: Based on review of the literature and consensus from a large multidisciplinary, international panel, minimum clinical criteria needed to determine BD/DNC in various circumstances were developed. RECOMMENDATIONS: Prior to evaluating a patient for BD/DNC, the patient should have an established neurologic diagnosis that can lead to the complete and irreversible loss of all brain function, and conditions that may confound the clinical examination and diseases that may mimic BD/DNC should be excluded. Determination of BD/DNC can be done with a clinical examination that demonstrates coma, brainstem areflexia, and apnea. This is seen when (1) there is no evidence of arousal or awareness to maximal external stimulation, including noxious visual, auditory, and tactile stimulation; (2) pupils are fixed in a midsize or dilated position and are nonreactive to light; (3) corneal, oculocephalic, and oculovestibular reflexes are absent; (4) there is no facial movement to noxious stimulation; (5) the gag reflex is absent to bilateral posterior pharyngeal stimulation; (6) the cough reflex is absent to deep tracheal suctioning; (7) there is no brain-mediated motor response to noxious stimulation of the limbs; and (8) spontaneous respirations are not observed when apnea test targets reach pH <7.30 and Paco2 ≥60 mm Hg. If the clinical examination cannot be completed, ancillary testing may be considered with blood flow studies or electrophysiologic testing. Special consideration is needed for children, for persons receiving extracorporeal membrane oxygenation, and for those receiving therapeutic hypothermia, as well as for factors such as religious, societal, and cultural perspectives; legal requirements; and resource availability. CONCLUSIONS AND RELEVANCE: This report provides recommendations for the minimum clinical standards for determination of brain death/death by neurologic criteria in adults and children with clear guidance for various clinical circumstances. The recommendations have widespread international society endorsement and can serve to guide professional societies and countries in the revision or development of protocols and procedures for determination of brain death/death by neurologic criteria, leading to greater consistency within and between countries.

Case-control study of end-of-life treatment preferences and costs following advance care planning for adults with end-stage kidney disease.

AIM: The aim of the present study was to examine the efficacy of advance care planning (ACP) to improve the likelihood that end-stage kidney disease (ESKD) patient's preferences will be known and adhered to at end-of-life. METHODS: A case-control study of a nurse-led ACP programme in adults with ESKD from a major tertiary hospital. The primary outcome was the proportion of patients whose preferences were known (by substitute decision maker and/or clinicians) and adhered to by their treating doctors. Secondary measures were health system resource use and costs ($AUD) for a nurse-led ACP intervention in the last 12-months of life. RESULTS: In total, 57 cases (38 men, mean age 73.8 years) and 57 historical controls (38 men, mean age 74.0 years) were included. Cases (38/57, 67%) were significantly more likely than controls (15/57, 26%) to have their preferences known and adhered to by their treating doctor at end-of-life (P < 0.001). Cases (33/40, 83%) were also significantly more likely to withdraw from dialysis in accordance with their preferences than controls (11/33, 33%) (P < 0.001). For cases, the average hospital costs in the last 12 months of life was AUD $99 077 (SD = $71 002) per patient. The total cost of the ACP programme in 2010/2011 was AUD $26 821. CONCLUSION: Advance care planning was associated with improvements in end-of-life care preferences being known and adhered to for people with ESKD.

A randomised controlled trial of an advance care planning intervention for patients with incurable cancer.

BACKGROUND: We modified and evaluated an advance care planning (ACP) intervention, which had been shown to improve compliance with patient's end of life (EoL) wishes, in a different patient population. METHODS: Patients with incurable cancer, and a Family Member (FM), were randomised one-to-one to usual care or usual care plus an ACP intervention, between April 2014 and January 2017. Oncologists and participants were non-blinded. ACP was based on the Respecting Patient Choices model, with an offer to provide individualised ranges for typical, best-case and worst-case scenarios for survival time. Seven facilitators (two oncology nurses, two nurses and three allied health professionals) delivered the intervention within 2 weeks of study enrolment. The primary outcome measure, assessed by interviewing the FM 3 months after patient death, was the FM perception that the patient's wishes were discussed, and met. RESULTS: Six hundred and sixty-five patients from seven Australian metropolitan oncology centres were referred for consideration by their oncologists, 444 (67%) met the study inclusion criteria and were approached by a study researcher. Two hundred and eight patients (47%) and their FM entered the trial as dyads. Fifty-three (46%) dyads in the ACP group and 63 (54%) dyads in the usual-care group had complete primary outcome data (p = 0.16). Seventy-nine patients and 53 FMs attended an ACP discussion. Mean length of discussion was 57 min. FMs from 23 (43%) dyads allocated to ACP and 21 (33%) dyads allocated usual care reported the patient's EoL wishes were discussed and met (difference 10%, 95% CI: -2 to 8, p = 0.27). There were no differences in EoL care received, patient satisfaction with care; FM satisfaction with care or with death; or FM well being. Rates of palliative care referral were high in both groups (97% vs 96%). CONCLUSIONS: A formal ACP intervention did not increase the likelihood that EoL care was consistent with patients' preferences.

An Interview Study of Patient and Caregiver Perspectives on Advance Care Planning in ESRD.

BACKGROUND: Advance care planning (ACP) empowers patients to consider and communicate their current and future treatment goals. However, it can be an emotionally charged process for patients with kidney disease and their caregivers. This study aimed to describe the perspectives and attitudes of patients with end-stage renal disease (ESRD) and their caregivers toward ACP. STUDY DESIGN: Qualitative study. SETTING & PARTICIPANTS: Patients with ESRD (n=24) and their caregivers (n=15) aged 36 to 91 years at various stages of ACP ("not commenced," "in progress," or "completed") from 3 renal services. METHODOLOGY: Semistructured interviews. ANALYTICAL APPROACH: Transcripts were analyzed using thematic analysis. RESULTS: 5 major themes were identified: articulating core values (avoiding futile and undignified treatment, reevaluating terms of dialysis, framing a life worth living, and refusing to be a burden), confronting conversations (signifying death and defeat, accepting inevitable death, and alleviating existential tension), negotiating mutual understanding (broaching taboos and assisting conflicted caregivers), challenging patient autonomy (family pressures to continue dialysis, grief diminishing caregivers' capacity, and leveraging support), and decisional disempowerment (lacking medical transparency and disappointment with clinical disinterest). LIMITATIONS: Only English-speaking patients/caregivers participated in the interview. CONCLUSIONS: ACP provides patients with ESRD and their caregivers a conduit for accepting and planning for impending death and to express treatment preferences based on self-dignity and value of living. However, ACP can be considered taboo, may require caregivers to overcome personal and decisional conflict, and may be complex if patients and caregivers are unable to accept the reality of the patient's illness. We suggest that ACP facilitators and clinicians make ACP more acceptable and less confrontational to patients and caregivers and that strategies be put in place to support caregivers who may be experiencing overwhelming grief or who have conflicting goals, particularly when they are called on to make end-of-life decisions.

Clinicians' Perspectives on Advance Care Planning for Patients With CKD in Australia: An Interview Study.

BACKGROUND: Advance care planning (ACP) empowers patients to consider and communicate their current and future treatment goals. However, ACP is not widely implemented in chronic kidney disease (CKD) care settings. This study aims to describe clinicians' beliefs, challenges, and perspectives of ACP in patients with CKD. STUDY DESIGN: Qualitative study. SETTING & PARTICIPANTS: Nephrologists (n=20), nurses (n=7), and social workers (n=4) with a range of experience in facilitating ACP for patients with CKD across Australia. METHODOLOGY: Semistructured interviews were digitally recorded and transcribed verbatim. ANALYTICAL APPROACH: Transcripts were analyzed using thematic analysis. RESULTS: 5 major themes were identified: facilitating informed decision making (avoiding preconceptions, conveying complete truths, focusing on supportive care, and synchronizing with evolving priorities), negotiating moral boundaries (contending with medical futility and respecting patient vs family autonomy), navigating vulnerable conversations (jeopardizing the therapeutic relationship, compromising professional confidence, emotionally invested, and enriching experiences), professional disempowerment (unsupportive culture, doubting logistical feasibility, and making uncertain judgments), and clarifying responsibilities (governing facilitation, managing tensions, and transforming multidisciplinary relationships). LIMITATIONS: Some findings may be specific to the Australian context. CONCLUSIONS: The tensions among themes reflect that ACP is paradoxically rewarding for clinicians because ACP empowers patients yet can expose personal and professional vulnerabilities. Clinicians believe that a more collaborative approach is needed, with increased efforts to identify the evolving and individualized needs and goals of patients with CKD. Models of ACP that address clinicians' personal and professional vulnerabilities when initiating ACP may foster greater confidence and cultural acceptance of ACP in the CKD setting.

Advance care planning in chronic kidney disease: A survey of current practice in Australia.

AIM: Advance care planning (ACP) in nephrology is widely advocated but not always implemented. The aims of this study were to describe current ACP practice and identify barriers/facilitators and perceived need for health professional education and chronic kidney disease (CKD)-specific approaches. METHODS: An anonymous cross-sectional survey was administered online. Nephrology health professionals in Australia and New Zealand were recruited via professional societies, email lists and nephrology conferences. Multiple regression explored the influence of respondents' attributes on extent of involvement in ACP and willingness to engage in future. RESULTS: A total of 375 respondents included nephrologists (23%), nurses (65%), social workers (4%) and others (8%) with 54% indicated that ACP at their workplace was performed ad hoc and 61% poorly. Perceived barriers included patient/family discomfort (84%), difficulty engaging families (83%), lack of clinician expertise (83%) and time (82%), health professional discomfort (72%), cultural/language barriers (65%), lack of private space (61%) and lack of formal policy/procedures (60%). Respondents overwhelmingly endorsed the need for more dialysis-specific ACP programs (96%) and education (95%). Whilst 85% thought ACP would be optimally performed by specially trained staff, comments emphasized that all clinicians should have a working proficiency. Respondents who were more willing to engage in future ACP tended to be non-physicians (odds ratio (OR) 4.96, 95% confidence intervals (CI) 1.74-14.07) and reported a greater need for CKD-specific ACP materials (OR 10.88, 95% CI 2.38-49.79). CONCLUSION: Advance care planning in nephrology needs support through education and CKD-specific resources. Endorsement by nephrologists is important. A multidisciplinary approach with a gradient of ACP expertise is also recommended.

Australian Psychiatrists' Support for Psychiatric Advance Directives: Responses to a Hypothetical Vignette.

This study examines whether Australian psychiatrists would support requests in a psychiatric advance directive (PAD) and the reasons underlying their decisions in response to a hypothetical vignette. An online survey was completed by 143 psychiatrists. Fewer than 3 out of 10 psychiatrists supported the patient to create a PAD which requested cessation of pharmacotherapy (27%) or remaining out of hospital and not being subject to an involuntary treatment order (24%) should their depression condition deteriorate. A thematic analysis showed that patient autonomy was the strongest theme among those who supported the patient to create a PAD, whereas the clinical profile of and risk to the patient and the professional or ethical imperative of the psychiatrist were strongest among those who were unsure about supporting the patient or who did not support the patient. These findings provide a challenge about how to fulfil obligations under the United Nations Convention on the Rights of Persons with Disabilities (2006).

Advance care planning in Australia: what does the law say?

Advance care planning (ACP) assists people to plan for their future health and personal care. ACP encourages a person to legally appoint a substitute decision maker (SDM) and to document any specific wishes regarding their future health care in an advance care directive (ACD). Formal documentation of wishes increases the chances that a person's wishes will be known and followed. However, one of the biggest impediments for doctors following the person's wishes is uncertainty surrounding the law, which is complicated and varies between the states and territories of Australia. SDM legislation varies regarding who can be appointed, how they are appointed, the powers that an SDM can be given and the decision-making principles that the SDM needs to follow. In circumstances where an SDM has not been appointed, the hierarchy for determining the default SDM for a person also varies between states. Although many states have legislated ACD forms allowing for documentation of a person's health care wishes, these forms allow for different things to be documented and have different requirements to be valid. The Australian population is mobile, with patients frequently moving between states. The status of ACP documentation created in a state other than the state in which a patient requires treatment also varies, with some states recognising interstate ACDs whereas others do not. This article outlines the legal status of ACDs, within Australian jurisdictions, including the legal validity of interstate ACDs, and argues that uniform laws and documents would assist with awareness and understanding of, and compliance with, ACDs.

Current advance care planning practice in the Australian community: an online survey of home care package case managers and service managers.

BACKGROUND: Advance care planning (ACP) is the process of planning for future healthcare that is facilitated by a trained healthcare professional, whereby a person's values, beliefs and treatment preferences are made known to guide clinical decision-making at a future time when they cannot communicate their decisions. Despite the potential benefits of ACP for community aged care clients the availability of ACP is unknown, but likely to be low. In Australia many of these clients receive services through Home Care Package (HCP) programs. This study aimed to explore current attitudes, knowledge and practice of advance care planning among HCP service managers and case managers. METHODS: An invitation to take part in a cross-sectional online survey was distributed by email to all HCP services across Australia in November 2012. Descriptive analyses were used to examine overall patterns of responses to each survey item in the full sample. RESULTS: 120 (response rate 25%) service managers and 178 (response rate 18%) case managers completed the survey. Only 34% of services had written ACP policies and procedures in place and 48% of case managers had previously completed any ACP training. In addition, although most case managers (70%) had initiated an ACP discussion in the past 12 months and viewed ACP as part of their role, the majority of the conversations (80%) did not result in documentation of the client's wishes and most (85%) of the case managers who responded did not believe ACP was done well within their service. CONCLUSIONS: This survey shows low organisational ACP systems and support for case managers and a lack of a normative approach to ACP across Australian HCP services. As HCPs become more prevalent it is essential that a model of ACP is developed and evaluated in this setting, so that clients have the opportunity to discuss and document their future healthcare wishes if they choose to.

Advance care planning in palliative care: a national survey of health professionals and service managers.

OBJECTIVE: To identify the attitudes, knowledge and practices regarding advance care planning (ACP) in palliative care. METHODS: A nationwide online survey was distributed to Australian palliative care services associated with the Palliative Care Outcomes Collaboration (n=105). Seventy-three health professionals (HPs) and 59 service managers completed the survey. RESULTS: Regarding ACP, 51% of service managers reported relevant policies and procedures were in place in their service and 44% included ACP in job descriptions. Most HPs were confident in undertaking ACP, including initiating discussions with patients and complying with documents; however, only 44% reported receiving ACP specific training. Although 58% of HPs reported having conversations about ACP with more than 11 patients in the past 6 months, only 44% of managers report that it is offered to most patients. Thirty per cent of HPs were aware of others not adhering to patient wishes in the past 6 months and only 43% of HPs (and 37% of managers) believed ACP is done well within their service. CONCLUSIONS: This first national survey examining ACP in palliative care services demonstrates there is a need to improve systems to support ACP and to understand circumstances in which ACP wishes are not followed.

Palliative care health professionals' experiences of caring for patients with advance care directives.

OBJECTIVE: To explore the health professionals' (HPs) perceptions and experiences of advance care directives (ACDs) and advance care planning in Australian palliative care services. METHODS: A nationwide survey of 105 palliative care services was conducted, with two HPs from each service invited to participate. A qualitative analysis of open responses about advance care planning was undertaken. RESULTS: Sixty questionnaires were returned with open responses. Most responders were nurses (75%), aged ≥40 years (80%) and with a mean of 12 years palliative care experience. Data were grouped into four key themes: (1) the ACD; (2) the process of developing ACDs; (3) the process of using ACDs; and (4) the consequences of having ACDs. Participants were positive about advance care planning, commenting that ongoing communication about end-of-life care ensures mutual understanding between patients, family and HPs. Provision of care was considered easier and more efficient with an ACD in place. ACDs were perceived to reduce distrust and conflict between family, friends and HPs, and promote communication. Suboptimal documentation, clarity and explicitness limited the usefulness of ACDs when they were available. CONCLUSIONS: Advance care planning benefits HPs, patients and their family. To maximise these benefits, ACDs need to be clear, comprehensive, medically relevant and transportable documents.

Advance care planning for adults with CKD: a systematic integrative review.

BACKGROUND: Recent clinical practice guidelines have highlighted the importance of advance care planning (ACP) for improving end-of-life care for people with chronic kidney disease (CKD). STUDY DESIGN: We conducted a systematic integrative review of the literature to inform future ACP practice and research in CKD, searching electronic databases in April 2013. Synthesis used narrative methods. SETTING & POPULATION: We focused on adults with a primary diagnosis of CKD in any setting. SELECTION CRITERIA FOR STUDIES: We included studies of any design, quantitative or qualitative. INTERVENTIONS: ACP was defined as any formal means taken to ensure that health professionals and family members are aware of patients' wishes for care in the event they become too unwell to speak for themselves. OUTCOMES: Measures of all kinds were considered of interest. RESULTS: 55 articles met criteria reporting on 51 discrete samples. All patient samples included people with CKD stage 5; 2 also included patients with stage 4. Seven interventions were tested; all were narrowly focused and none was evaluated by comparing wishes for end-of-life care with care received. One intervention demonstrated effects on patient and family outcomes in the form of improved well-being and anxiety following sessions with a peer mentor. Insights from qualitative studies that have not been used to inform interventions include the importance of instilling patient confidence that their advance directives will be enacted and discussing decisions about (dis)continuing dialysis therapy separately from "aggressive" life-sustaining treatments (eg, ventilation). LIMITATIONS: Although quantitative and qualitative findings were integrated according to best practice, methods for this are in their infancy. CONCLUSIONS: Research on ACP in patients with CKD is limited, especially intervention studies. Interventions in CKD should attend to barriers and facilitators at the levels of patient, caregiver, health professional, and system. Intervention studies should measure impact on compliance with patient wishes for end-of-life care.

Induction of prehospital therapeutic hypothermia after resuscitation from nonventricular fibrillation cardiac arrest*.

OBJECTIVE: To evaluate the effects on temperature and outcome at hospital discharge of a pre-hospital rapid infusion of large volume, ice-cold intravenous Hartmann's solution in patients with out-of-hospital cardiac arrest and an initial cardiac rhythm of asystole or pulseless electrical activity. DESIGN: Prospective, randomized, controlled clinical trial. SETTING: Pre-hospital emergency medical service and 12 critical care units in Melbourne, Australia. PATIENTS: One hundred and sixty three patients who had been resuscitated from cardiac arrest with an initial cardiac rhythm of asystole or pulseless electrical activity. INTERVENTIONS: : Patients were randomized to either pre-hospital cooling using a rapid infusion of up to two litres ice-cold Hartmann's solution (82 patients) or cooling after hospital admission (81 patients). The planned duration of therapeutic hypothermia (32 °C-34 °C) in both groups was 24 hrs. MEASUREMENTS AND MAIN RESULTS: Patients allocated to pre-hospital cooling received a median of 1500 ml of ice-cold fluid. This resulted in a mean decrease in core temperature of 1.4 °C compared with 0.2 °C in hospital cooled patients (p < .001). The time to therapeutic hypothermia (<34 °C) was 3.2 hrs in the pre-hospital cooled group compared with 4.8 hrs in the hospital cooled group (p = .0328). Both groups received a mean of 15 hrs cooling in the hospital and only 7 patients in each group were cooled for 24 hrs. Overall, there was no difference in outcomes at hospital discharge with favorable outcome (discharge from hospital to home or rehabilitation) in 10 of 82 (12%) in the pre-hospital cooled patients, compared with 7 of 81 (9%) in the hospital cooled patients (p = .50). In the patients with a cardiac cause of the arrest, 8 of 47 patients (17%) who received pre-hospital cooling had a favorable outcome at hospital discharge compared with 3 of 43 (7%) in the hospital cooled group (p = .146). CONCLUSIONS: In adults who have been resuscitated from out-of-hospital cardiac arrest with an initial cardiac rhythm of asystole or pulseless electrical activity, pre-hospital cooling using a rapid infusion of large-volume, ice cold intravenous Hartmann's solution decreases core temperature at hospital arrival and decreases the time to therapeutic hypothermia. In patients with a cardiac cause of the arrest, this treatment may increase the rate of favorable outcome at hospital discharge. Further larger studies should evaluate the effects of pre-hospital cooling when the initial cardiac rhythm is asystole or pulseless electrical activity, particularly in patients with a cardiac cause of the arrest.

A systematic review and meta-analysis of clinical trials of thyroid hormone administration to brain dead potential organ donors.

OBJECTIVES: To review all published clinical studies of thyroid hormone administration to brain-dead potential organ donors. METHODS: A search of PubMed using multiple search terms retrieved 401 publications including 35 original reports describing administration of thyroid hormone to brain-dead potential organ donors. Detailed review of the 35 original reports led to identification of two additional publications not retrieved in the original search. The 37 original publications reported findings from 16 separate case series or retrospective audits and seven randomized controlled trials, four of which were placebo-controlled. Meta-analysis was restricted to the four placebo-controlled randomized controlled trials. RESULTS: Whereas all case series and retrospective audits reported a beneficial effect of thyroid hormone administration, all seven randomized controlled trials reported no benefit of thyroid hormone administration either alone or in combination with other hormonal therapies. In four placebo-controlled trials including 209 donors, administration of thyroid hormone (n=108) compared with placebo (n=101) had no significant effect on donor cardiac index (pooled mean difference, 0.15 L/min/m²; 95% confidence interval -0.18 to 0.48). The major limitation of the case series and retrospective audits was the lack of consideration of uncontrolled variables that confound interpretation of the results. A limitation of the randomized controlled trials was that the proportion of donors who were hemodynamically unstable or marginal in other ways was too small to exclude a benefit of thyroid hormone in this subgroup. CONCLUSIONS: The findings of this systematic review do not support a role for routine administration of thyroid hormone in the brain-dead potential organ donor. Existing recommendations regarding the use of thyroid hormone in marginal donors are based on low-level evidence.

Induction of therapeutic hypothermia by paramedics after resuscitation from out-of-hospital ventricular fibrillation cardiac arrest: a randomized controlled trial.

BACKGROUND: Therapeutic hypothermia is recommended for the treatment of neurological injury after resuscitation from out-of-hospital cardiac arrest. Laboratory studies have suggested that earlier cooling may be associated with improved neurological outcomes. We hypothesized that induction of therapeutic hypothermia by paramedics before hospital arrival would improve outcome. METHODS AND RESULTS: In a prospective, randomized controlled trial, we assigned adults who had been resuscitated from out-of-hospital cardiac arrest with an initial cardiac rhythm of ventricular fibrillation to either prehospital cooling with a rapid infusion of 2 L of ice-cold lactated Ringer's solution or cooling after hospital admission. The primary outcome measure was functional status at hospital discharge, with a favorable outcome defined as discharge either to home or to a rehabilitation facility. A total of 234 patients were randomly assigned to either paramedic cooling (118 patients) or hospital cooling (116 patients). Patients allocated to paramedic cooling received a median of 1900 mL (first quartile 1000 mL, third quartile 2000 mL) of ice-cold fluid. This resulted in a mean decrease in core temperature of 0.8 degrees C (P=0.01). In the paramedic-cooled group, 47.5% patients had a favorable outcome at hospital discharge compared with 52.6% in the hospital-cooled group (risk ratio 0.90, 95% confidence interval 0.70 to 1.17, P=0.43). CONCLUSIONS: In adults who have been resuscitated from out-of-hospital cardiac arrest with an initial cardiac rhythm of ventricular fibrillation, paramedic cooling with a rapid infusion of large-volume, ice-cold intravenous fluid decreased core temperature at hospital arrival but was not shown to improve outcome at hospital discharge compared with cooling commenced in the hospital.

Treatment of comatose survivors of out-of-hospital cardiac arrest with induced hypothermia.

BACKGROUND: Cardiac arrest outside the hospital is common and has a poor outcome. Studies in laboratory animals suggest that hypothermia induced shortly after the restoration of spontaneous circulation may improve neurologic outcome, but there have been no conclusive studies in humans. In a randomized, controlled trial, we compared the effects of moderate hypothermia and normothermia in patients who remained unconscious after resuscitation from out-of-hospital cardiac arrest. METHODS: The study subjects were 77 patients who were randomly assigned to treatment with hypothermia (with the core body temperature reduced to 33 degrees C within 2 hours after the return of spontaneous circulation and maintained at that temperature for 12 hours) or normothermia. The primary outcome measure was survival to hospital discharge with sufficiently good neurologic function to be discharged to home or to a rehabilitation facility. RESULTS: The demographic characteristics of the patients were similar in the hypothermia and normothermia groups. Twenty-one of the 43 patients treated with hypothermia (49 percent) survived and had a good outcome--that is, they were discharged home or to a rehabilitation facility--as compared with 9 of the 34 treated with normothermia (26 percent, P=0.046). After adjustment for base-line differences in age and time from collapse to the return of spontaneous circulation, the odds ratio for a good outcome with hypothermia as compared with normothermia was 5.25 (95 percent confidence interval, 1.47 to 18.76; P=0.011). Hypothermia was associated with a lower cardiac index, higher systemic vascular resistance, and hyperglycemia. There was no difference in the frequency of adverse events. CONCLUSIONS: Our preliminary observations suggest that treatment with moderate hypothermia appears to improve outcomes in patients with coma after resuscitation from out-of-hospital cardiac arrest.

Advance care planning in patients with incurable cancer: study protocol for a randomised controlled trial.

INTRODUCTION: There is limited evidence documenting the effectiveness of Advance Care Planning (ACP) in cancer care. The present randomised trial is designed to evaluate whether the administration of formal ACP improves compliance with patients' end-of-life (EOL) wishes and patient and family satisfaction with care. METHODS AND ANALYSIS: A randomised control trial in eight oncology centres across New South Wales and Victoria, Australia, is designed to assess the efficacy of a formal ACP intervention for patients with cancer. Patients with incurable cancer and an expected survival of 3-12 months, plus a nominated family member or friend will be randomised to receive either standard care or standard care plus a formal ACP intervention. The project sample size is 210 patient-family/friend dyads. The primary outcome measure is family/friend-reported: (1) discussion with the patient about their EOL wishes and (2) perception that the patient's EOL wishes were met. Secondary outcome measures include: documentation of and compliance with patient preferences for medical intervention at the EOL; the family/friend's perception of the quality of the patient's EOL care; the impact of death on surviving family; patient-family and patient-healthcare provider communication about EOL care; patient and family/friend satisfaction with care; quality of life of patient and family/friend subsequent to trial entry, the patient's strength of preferences for quality of life and length of life; the costs of care subsequent to trial entry and place of death. ETHICS AND DISSEMINATION: Ethical approval was received from the Sydney Local Health District (RPA Zone) Human Research Ethical Committee, Australia (Protocol number X13-0064). Study results will be submitted for publication in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: Pre-results; ACTRN12613001288718.

Feasibility and acceptability of advance care planning in elderly Italian and Greek speaking patients as compared to English-speaking patients: an Australian cross-sectional study.

OBJECTIVES: To assess the feasibility and acceptability of facilitated advance care planning (ACP) discussions in elderly Italian and Greek-speaking inpatients compared to English-speaking inpatients. DESIGN, SETTING AND PARTICIPANTS: This cross-sectional study with convenience sampling was conducted in Melbourne, Australia, and recruited hospital inpatients with medical decision-making capacity, aged 65 years or above, who spoke Greek (25 patients), Italian (24 patients) or English (63 patients). INTERVENTION: Facilitated ACP was offered, aiming to assists patients to consider and discuss their goals, values, beliefs and future treatment wishes with their family and doctor; to help them consider how they would like healthcare decisions made in the future if they become unable to do this for themselves; and to complete advance care directives. MAIN OUTCOME MEASURES: The completion of ACP discussions, their duration, advance care directive completion and utilisation of interpreters. RESULTS: Of 112 patients, 109 (97%) had at least one discussion, 63 (54%) completed advance care directives, either nominating a substitute decision-maker, documenting their wishes or both, and 76 (68%) included family in discussions. The median duration of discussions for all patients was slightly more than 1 h, over two visits. There were no differences between the Greek-speaking and the Italian-speaking patients, or between the Non-English speaking and the English-speaking patients in any of these measures. Only 14 non-English speaking patients, (30%) utilised interpreters, but when utilised, patients were much more likely (p<0.005) to complete advance care directives. CONCLUSIONS: Facilitated ACP in elderly Italian and Greek-speaking patients is feasible, acceptable and is similar to that for English-speaking patients.
