Background Coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented pressure on healthcare system globally. Lack of high-quality evidence on the respiratory management of COVID-19-related acute respiratory failure (C-ARF) has resulted in wide variation in clinical practice. Methods Using a Delphi process, an international panel of 39 experts developed clinical practice statements on the respiratory management of C-ARF in areas where evidence is absent or limited. Agreement was defined as achieved when > 70% experts voted for a given option on the Likert scale statement or > 80% voted for a particular option in multiple-choice questions. Stability was assessed between the two concluding rounds for each statement, using the non-parametric Chi-square (χ2) test (p < 0·05 was considered as unstable). Results Agreement was achieved for 27 (73%) management strategies which were then used to develop expert clinical practice statements. Experts agreed that COVID-19-related acute respiratory distress syndrome (ARDS) is clinically similar to other forms of ARDS. The Delphi process yielded strong suggestions for use of systemic corticosteroids for critical COVID-19; awake self-proning to improve oxygenation and high flow nasal oxygen to potentially reduce tracheal intubation; non-invasive ventilation for patients with mixed hypoxemic-hypercapnic respiratory failure; tracheal intubation for poor mentation, hemodynamic instability or severe hypoxemia; closed suction systems; lung protective ventilation; prone ventilation (for 16–24 h per day) to improve oxygenation; neuromuscular blocking agents for patient-ventilator dyssynchrony; avoiding delay in extubation for the risk of reintubation; and similar timing of tracheostomy as in non-COVID-19 patients. There was no agreement on positive end expiratory pressure titration or the choice of personal protective equipment. Conclusion Using a Delphi method, an agreement among experts was reached for 27 statements from which 20 expert clinical practice statements were derived on the respiratory management of C-ARF, addressing important decisions for patient management in areas where evidence is either absent or limited.

There is growing interest in the long-term outcomes of patients surviving out-of-hospital cardiac arrest (OHCA). This paper aims to summarise the available literature on the long-term cognitive, health-related quality of life (QoL) and mental health outcomes of survivors of OHCA. Between 30 and 50% of survivors of OHCA experience cognitive deficits for up to several years post-discharge. Deficits of attention, declarative memory, executive function, visuospatial abilities and verbal fluency are commonly reported. Survivors of OHCA appear to report high rates of mental illness, with up to 61% experiencing anxiety, 45% experiencing depression and 27% experiencing post-traumatic stress. Fatigue appears to be a commonly reported longterm outcome for survivors of OHCA. Investigations of long-term QoL for these patients have produced mixed findings. Carers of survivors of OHCA report high rates of depression, anxiety and post-traumatic stress, with insufficient social and financial support. The heterogeneous range of instruments used to assess cognitive function and QoL prevent any clear conclusions being drawn from the available literature. The potential biases inherent in this patient population and the interaction between QoL, cognitive performance and mental health warrant further investigation, as does the role of post-discharge support services in improving long-term patient outcomes.
IntroductionCOPD is a leading cause of morbidity and mortality worldwide. Patients with COPD often require admission to intensive care units (ICU) during an acute exacerbation.ObjectiveThis study aimed to identify the factors independently associated with hospital mortality in patients requiring ICU admission for acute exacerbation of COPD.MethodsPatients admitted to the ICU of Frankston Hospital between January 2005 and June 2016 with an admission diagnosis of COPD were retrospectively identified from ICU databases. Patients’ comorbidities, arterial blood gas results, and in-patient interventions were retrieved from their medical records. Outcomes analyzed included hospital and ICU length of stay (LOS) and mortality.ResultsA total of 305 patients were included. Mean age was 67.4 years. A total of 77% of patients required non-invasive ventilation; and 38.7% required invasive mechanical ventilation (IMV) for a median of 127.2 hours (SD =179.5). Mean ICU LOS was 4.5 days (SD =5.96), and hospital LOS was 11.6 days (SD =13). In-hospital mortality was 18.7%. Multivariate analysis revealed that patient age (odds ratio [OR] =1.06; 95% CI: 1.031–1.096), ICU LOS (OR =1.26; 95% CI: 1.017–1.571), Acute Physiology and Chronic Health Evaluation-II score (OR =1.07; 95% CI: 1.012–1.123), and requirement for IMV (OR =4.09; 95% CI: 1.791–9.324) to be significantly associated with in-hospital mortality.ConclusionPatient age, requirement for IMV, and illness severity were associated with poor patient outcomes.
