RESUMO
INTRODUCTION: Palliative care within intensive care units (ICU) benefits decision-making, symptom control, and end-of-life care. It has been shown to reduce the length of ICU stay and the use of non-beneficial and unwanted life-sustaining therapies. However, it is often initiated late or not at all. There is increasing evidence to support screening ICU patients using palliative care referral criteria or "triggers". The aim of the project was to assess the need for palliative care referral during ICU admission using "trigger" tools. METHODS: Electronic record review of cancer patients who died in or within 30 days of discharge from oncology ICU, between 2016 and 2018. Patients referred to palliative care before or during ICU admission were identified. Three sets of palliative care referral "triggers" were applied: one that is being tested locally and two internationally derived tools. The proportion of patients who met any of these triggers during their final ICU admission was calculated. RESULTS: Records of 149 patients were reviewed: median age 65 (range 20-83). Most admissions (89%) were unplanned, with the most common diagnoses being haemato-oncology (31%) and gastrointestinal (16%) cancers. Most (73%) were unknown to palliative care pre-ICU admission; 44% were referred between admission and death. The median time from referral to death was 0 day (range 0-19). On ICU admission, 97-99% warranted referral to palliative care using locally and internationally derived triggers. CONCLUSION: All "trigger" tools identified a high proportion of patients who may have warranted a palliative care referral either before or during admission to ICU. The routine use of trigger tools could help streamline referral pathways and underpin the development of an effective consultative model of palliative care within the ICU setting to enhance decision-making about appropriate treatment and patient-centred care.

During the on-going COVID-19 pandemic a number of key public health services have been severely impacted. These include elective surgical services due to the synergetic resources required to provide both perioperative surgical care whilst also treating acute COVID-19 patients and also the poor outcomes associated with surgical patients who develop COVID-19 in the perioperative period. This article discusses the important principles and concepts for providing important surgical services during the COVID-19 pandemic based on the model of the RMCancerSurgHub which is providing surgical cancer services for a population of approximately 2 million people across London during the pandemic. The model focusses on creating local and regional hub centres which provide urgent treatment for surgical patients in an environment that is relatively protected from the burden of COVID-19 illness. The model extensively utilises the extended multidisciplinary team to allow for a flexible approach with core services delivered in 'clean' sites which can adapt to viral surges. A key requirement is that of a clinical prioritisation process which allows for equity in access within and between specialties ensuring that patients are treated on the basis of greatest need, while at the same time protecting those whose conditions can safely wait from exposure to the virus. Importantly, this model has the ability to scale-up activity and lead units and networks into the recovery phase. The model discussed is also broadly applicable to providing surgical services during any viral pandemic.

BACKGROUND: Critical care and palliative care professionals treat and support seriously ill patients on a daily basis, and the possibility of burnout may be high. The consequences of burnout can include moral injury and distress, and compassion fatigue, which are detrimental to both care and staff. AIMS AND OBJECTIVES: To explore the incidence of moral distress in areas at high risk of burnout in a large cancer centre and to explore possible measures for addressing moral distress. DESIGN: A cross-sectional survey. METHODS: The Maslach Burnout Inventory was administered to critical care, critical care outreach, and palliative care teams in a specialist tertiary cancer centre. Open questions on supportive measures were also included. Burnout data were categorised into three domains of emotional exhaustion, depersonalization and personal accomplishment, and free-text analysis was conducted on the open-question data. RESULTS: A total of 63 professionals responded across the teams (45% response rate). A low level of burnout was observed in the emotional exhaustion domain; depersonalization was higher in the critical care professionals; and overall, personal accomplishment was higher than normative scores. Free-text analysis highlighted three categories of responses: Debriefing, Managing emotional well-being, and Valuing individuals. There was a need to proactively recognize issues; undertake more debriefs; and open forums regarding cases, particularly with difficult deaths. Engaging all professionals, support to deal with families, and mandatory moral distress and resilience training were suggested, alongside a focus on team building through external activities such as group relaxation sessions and walks. CONCLUSIONS: This study demonstrated a relatively low incidence of emotional exhaustion and depersonalization, and a slightly higher sense of personal accomplishment than normative scores despite staff working in an environment where high levels of burnout were expected. RELEVANCE TO CLINICAL PRACTICE: Staff highlighted possible solutions to reduce burnout, which included debriefing, managing emotional well-being, and valuing individuals.

BACKGROUND: The study objective was to assess the influence of neutropenia on outcome of critically ill cancer patients by meta-analysis of individual data. Secondary objectives were to assess the influence of neutropenia on outcome of critically ill patients in prespecified subgroups (according to underlying tumor, period of admission, need for mechanical ventilation and use of granulocyte colony stimulating factor (G-CSF)). METHODS: Data sources were PubMed and the Cochrane database. Study selection included articles focusing on critically ill cancer patients published in English and studies in humans from May 2005 to May 2015. For study selection, the study eligibility was assessed by two investigators. Individual data from selected studies were obtained from corresponding authors. RESULTS: Overall, 114 studies were identified and authors of 30 studies (26.3% of selected studies) agreed to participate in this study. Of the 7515 included patients, three were excluded due to a missing major variable (neutropenia or mortality) leading to analysis of 7512 patients, including 1702 neutropenic patients (22.6%). After adjustment for confounders, and taking study effect into account, neutropenia was independently associated with mortality (OR 1.41; 95% CI 1.23-1.62; P = 0.03). When analyzed separately, neither admission period, underlying malignancy nor need for mechanical ventilation modified the prognostic influence of neutropenia on outcome. However, among patients for whom data on G-CSF administration were available (n = 1949; 25.9%), neutropenia was no longer associated with outcome in patients receiving G-CSF (OR 1.03; 95% CI 0.70-1.51; P = 0.90). CONCLUSION: Among 7512 critically ill cancer patients included in this systematic review, neutropenia was independently associated with poor outcome despite a meaningful survival. Neutropenia was no longer significantly associated with outcome in patients treated by G-CSF, which may suggest a beneficial effect of G-CSF in neutropenic critically ill cancer patients. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015026347 . Date of registration: Sept 18 2015.

PURPOSE OF REVIEW: Severe infections in neutropenic patients can rapidly progress to septic shock and multiorgan failure with a high associated mortality. In this article we discuss current practice, emerging trends and controversies, including the prophylactic and empiric use of antimicrobial therapy, and advances in cellular and immunotherapy. RECENT FINDINGS: Neutropenia is no longer a consistent factor predicting poor outcome in haematological patients admitted to the ICU. Severe infections in neutropenic patients are often polymicrobial, and pathogen resistance remains a challenge. Invasive fungal infection is still predictive of poor outcome. There has been a rapid expansion in the diagnostics and treatment modalities available for patients with invasive fungal infection. Use of growth factors, polyvalent immunoglobulin, and cellular therapy appear to be of value in certain groups of patients. There is a move away from the use of noninvasive ventilation and the use of high-flow nasal oxygen therapy is one of a number of novel respiratory support strategies that is yet to be evaluated in this patient population. SUMMARY: Translation of current advances in antimicrobial, cellular and immunotherapy, and diagnostics to aid clinical management by the bedside is important in reducing morbidity and mortality for neutropenic patients with severe infection.

Introduction: Immune checkpoint inhibitors (ICIs) are increasingly a standard of care for many cancers; these agents can result in immune-related adverse events (irAEs) including fever, which is common but can rarely be associated with systemic immune activation (SIA or acquired HLH). Methods: All consecutive patients receiving ICIs in the Drug Development Unit of the Royal Marsden Hospital between May 2014 and November 2019 were retrospectively reviewed. Patients with fever ≥ 38°C or chills/rigors (without fever) ≤ 6 weeks of commencing ICIs were identified for clinical data collection. Results: Three patients met diagnostic criteria for SIA/HLH with median time to onset of symptoms of 10 days. We describe the clinical evolution, treatment used, and outcomes for these patients. High-dose steroids are used first-line with other treatments, such as tocilizumab, immunoglobulin and therapeutic plasmapheresis can be considered for steroid-refractory SIA/HLH. Conclusion: SIA/HLH post ICI is a rare but a potentially fatal irAE that presents with fever and a constellation of nonspecific symptoms. Early recognition and timely treatment are key to improving outcomes.
RESUMO
PURPOSE: The number of averted deaths due to therapeutic advances in oncology and hematology is substantial and increasing. Survival of critically ill cancer patients has also improved during the last 2 decades. However, these data stem predominantly from unadjusted analyses. The aim of this study was to assess the impact of ICU admission year on short-term survival of critically ill cancer patients, with special attention on those with neutropenia. METHODS: Systematic review and meta-analysis of individual data according to the guidelines of meta-analysis of observational studies in epidemiology. DATASOURCE: Pubmed and Cochrane databases. ELIGIBILITY CRITERIA: Adult studies published in English between May 2005 and May 2015. RESULTS: Overall, 7354 patients were included among whom 1666 presented with neutropenia at ICU admission. Median ICU admission year was 2007 (IQR 2004-2010; range 1994-2012) and median number of admissions per year was 693 (IQR 450-1007). Overall mortality was 47.7%. ICU admission year was associated with a progressive decrease in hospital mortality (OR per year 0.94; 95% CI 0.93-0.95). After adjustment for confounders, year of ICU admission was independently associated with hospital mortality (OR for hospital mortality per year: 0.96; 95% CI 0.95-0.97). The association was also seen in patients with neutropenia but not in allogeneic stem cell transplant recipients. CONCLUSION: After adjustment for patient characteristics, severity of illness and clustering, hospital mortality decreased steadily over time in critically ill oncology and hematology patients except for allogeneic stem cell transplant recipients.

OBJECTIVE: Intraabdominal hypertension reduces organ blood flow. Restoring abdominal perfusion pressure (APP) may restore renal blood flow, especially when sepsis is present. The effects of intra-abdominal pressure (IAP), followed by restoration of APP with norepinephrine, on renal blood flow were determined. DESIGN: Longitudinal study with bacteremia after nonbacteremic (control) conditions. SETTING: University animal laboratory. SUBJECTS: Ten anesthetized mongrel dogs. INTERVENTIONS: IAP was raised to 10, 20, and 30 mm Hg, using intra-abdominal bags filled with saline. After each intervention, decompression was achieved by emptying the bag. Bacteremia was induced by injection of Escherichia coli. Cardiac output and renal blood flow were measured using surgically placed flow probes. Norepinephrine infusion was used to restore the mean arterial pressure to baseline at each IAP. A hypervolemic circulation was maintained throughout by infusing saline. MEASUREMENTS AND MAIN RESULTS: Induction of bacteremia resulted in significant decreases in blood pressure, cardiac output, and renal blood flow (p < .01). Serial increases in IAP decreased cardiac output and renal blood flow both in control and bacteremic dogs (p < .001). These decreases were substantially corrected by abdominal decompression. In nonbacteremic control conditions, restoring APP back to baseline with norepinephrine did not fully restore cardiac output and renal blood flow (p < .001). However, in bacteremic conditions, norepinephrine was able to substantially restore cardiac output and renal blood flow to bacteremic baseline at all levels of IAP. In bacteremic conditions, the renal perfusion fraction returned to bacteremic baseline levels after correction of APP with norepinephrine and after decompression. CONCLUSIONS: Restoration of APP using norepinephrine improves renal blood flow in bacteremic animals with IAPs up to 30 mm Hg, and maintaining a therapeutic APP may preserve renal blood flow in patients with intra-abdominal hypertension who are at risk of IAP-induced renal injury but who have yet to meet accepted criteria for surgical decompression.

BACKGROUND: Decisions to forgo life-sustaining medical treatments in terminally ill patients are challenging, but ones that all doctors must face. Few studies have evaluated the impact of medical training on medical students' attitudes towards end-of-life decisions and none have compared them with an age-matched group of non-medical students. OBJECTIVE: To assess the effect of medical education on medical students' attitudes towards end-of-life decisions in acutely ill patients. DESIGN: Cross-sectional study. PARTICIPANTS: Four hundred and two students at The Chinese University of Hong Kong. MEASUREMENTS: Completion of a questionnaire focused on end-of-life decisions. MAIN RESULTS: The number of students who felt that cardiopulmonary resuscitation must always be provided was higher in non-medical students (76/90 (84%)) and medical students with less training (67/84 (80%) in year 1 vs. 18/67 (27%) in year 5) (p < 0.001). Discontinuing life-support therapy was more accepted among senior medical students compared to junior medical and non-medical students (27/66 (41%) in year 5 vs. 18/83 (22%) in year 1 and 20/90 (22%) in non-medical students) (p = 0.003). An unexpectedly large proportion of non-medical students (57/89 (64%)) and year 1 medical students (42/84 (50%)) found it acceptable to administer fatal doses of drugs to patients with limited prognosis. Euthanasia was less accepted with more years of training (p < 0.001). When making decisions regarding limitation of life-support therapy, students chose to involve patients (98%), doctors (92%) and families (73%) but few chose to involve nurses (38%). CONCLUSIONS: Medical students' attitudes towards end-of-life decisions changed during medical training and differed significantly from those of non-medical students.

BACKGROUND: Adaptive-support ventilation (ASV) is a minute ventilation-controlled mode governed by a closed-loop algorithm. With ASV, tidal volume and respiratory rate are automatically adjusted to minimize work of breathing. Studies indicate that ventilation in ASV enables more rapid weaning. The authors conducted a randomized controlled trial to determine whether ventilation in ASV results in a shorter time to extubation than pressure-regulated volume-controlled ventilation with automode (PRVCa) after cardiac surgery. METHODS: Fifty patients were randomly assigned to ASV or PRVCa after elective coronary artery bypass grafting. Respiratory weaning progressed through three phases: phase 1 (controlled ventilation), phase 2 (assisted ventilation), and phase 3 (T-piece trial), followed by extubation. The primary outcome was duration of intubation (sum of phases 1-3). Secondary outcomes were duration of mechanical ventilation (sum of phases 1 and 2), number of arterial blood gas samples, and manual ventilator setting changes made before extubation. RESULTS: Forty-eight patients completed the study. The median duration of intubation was significantly shorter in the ASV group than in the PRVCa group (300 [205-365] vs. 540 [462-580] min; P < 0.05). This difference was due to a reduction in the duration of mechanical ventilation (165 [120-195] vs. 480 [360-510] min; P < 0.05). There were no significant differences between the ASV and PRVCa groups in the number of arterial blood gas samples taken or manual ventilator setting changes made. CONCLUSIONS: ASV is associated with earlier extubation, without an increase in clinician intervention, when compared with PRVCa in patients undergoing uncomplicated cardiac surgery.

With a chronic shortage of doctors in intensive care, alternative roles are being explored. One of these is the role of the Advanced Critical Care Practitioner. The Advanced Critical Care Practitioner Curriculum was developed by the Faculty of Intensive Care Medicine and is used to provide a structured programme of training. The Advanced Critical Care Practitioner programme consists of an academic and clinical component. This article outlines a practical approach of how the programme was developed and is currently being delivered at a single institution. This new advanced practice role offers opportunities to fill gaps in the medical workforce, improve continuity of patient care, provide mentoring and training for less experienced staff as well as offering a rewarding clinical role.
RESUMO
AIM: To describe a course designed to help medical undergraduates develop the necessary competencies to recognise and manage acutely ill patients. MATERIALS AND METHODS: Primary description by the authors of the content, development and implementation of a course designed to teach competencies recommended by the Acute Care Undergraduate Teaching (ACUTE) project of the Resuscitation Council (UK) and Intercollegiate Board of Training in Intensive Care Medicine. The course format was designed to balance best teaching methods within the context of limited available teaching time and resources. Various components of the course were rated by 155 final year medical students who attended the course. RESULTS: A one and a half day integrated acute care course based on self-learning (course manual, CD-ROM, web material), lectures, interactive tutorials, skill stations and formative and summative assessment is described. The course addresses 55/71 (77%) of competencies considered important by the ACUTE project. It was well accepted by medical students and on a scale of 1 (poor) to 5 (excellent) median student ratings of various components of the course ranged from 4-5. CONCLUSION: The course offers a method of teaching acute care for medical undergraduates in an educationally sound, resource-efficient manner.

BACKGROUND: As influenza A/H5N1 spreads around the globe the risk of an epidemic increases. DISCUSSION: Review of the cases of influenza A/H5N1 reported to date demonstrates that it causes a severe illness, with a high proportion of patients (63%) requiring advanced organ support. Of these approx. 68% develop multiorgan failure, at least 54% develop acute respiratory distress syndrome, and 90% die. Disease progression is rapid, with a median time from presentation to hospital to requirement for advanced organ support of only 2 days. CONCLUSION: The infectious nature, severity and clinical manifestations of the disease and its potential for pandemic spread have considerable implications for intensive care in terms of infection control, patient management, staff morale and intensive care expansion.

Rituximab is used for treatment of multiple haematological cancers. Caution for use is advised in patients with significant cardiorespiratory disease due to known cases of exacerbations of angina and arrhythmias. However, its cardiotoxicity profile is not as well recognised as other monoclonal antibodies such as transtuzumab. We report a case of a 66-year-old man who developed Takotsubo's cardiomyopathy (TC) after an elective infusion of rituximab. This case is exceptional in that rituximab has not been linked to TC, and the vast majority of chemotherapy-linked and immunotherapy-linked TC reactions have occurred during initial infusions. We also discuss the different mechanisms which link TC to immunotherapy and chemotherapy, and propose that there may be a potential for risk-stratifying recipients of this frequently used immunotherapy prior to administering treatment.

BACKGROUND: There have been few studies that have evaluated the quality of end-of-life care (EOLC) for cancer patients in the ICU. The aim of this study was to explore the quality of transition to EOLC for cancer patients in ICU. METHODS: The study was undertaken on medical patients admitted to a specialist cancer hospital ICU over 6 months. Quantitative and qualitative methods were used to explore quality of transition to EOLC using documentary evidence. Clinical parameters on ICU admission were reviewed to determine if they could be used to identify patients who were likely to transition to EOLC during their ICU stay. RESULTS: Of 85 patients, 44.7% transitioned to EOLC during their ICU stay. Qualitative and quantitative analysis of the patients' records demonstrated that there was collaborative decision-making between teams, patients and families during transition to EOLC. However, 51.4 and 40.5% of patients were too unwell to discuss transition to EOLC and DNACPR respectively. In the EOLC cohort, 76.3% died in ICU, but preferred place of death known in only 10%. Age, APACHE II score, and organ support, but not cancer diagnosis, were identified as associated with transition to EOLC (p = 0.017, p < 0.0001 and p = 0.001). CONCLUSIONS: Advanced EOLC planning in patients with progressive disease prior to acute deterioration is warranted to enable patients' wishes to be fulfilled and ceiling of treatments agreed. Better documentation and development of validated tools to measure the quality EOLC transition on the ICU are needed.
