The College of Intensive Care Medicine of Australia and New Zealand is responsible for credentialling trainees for specialist practice in intensive care medicine for the safety of patients and the community. This involves defining trainees' performance standards and testing trainees against those standards to ensure safe practice. The second part examination performed towards the end of the training program is a high-stakes assessment. ⋯ There is increasing expectation for medical specialist training colleges to provide fair and transparent assessment processes to enable defensible decisions regarding trainee progression. Examinations are a surrogate marker of clinical performance with advantages, disadvantages and inevitable compromises. This article evaluates the Hot Case examination using Kane's validity framework and van der Vleuten's utility equation, and identifies issues with validity and reliability which could be managed through an ongoing improvement process.

Objective: To describe the pattern of acute illness and 6-month mortality and health-related quality-of-life outcomes for a cohort of Aboriginal and Torres Strait Islander patients presenting with septic shock. Design: Nested cohort study of Aboriginal and Torres Strait Islander participants recruited to a large randomised controlled trial of corticosteroid treatment in patients with septic shock. Setting: Royal Darwin Hospital, Northern Territory. ⋯ When compared with the matched population drawn from the broader ADRENAL cohort, there was no significant difference in 90-day mortality (12/60 v 16/61; adjusted odds ratio, 1.43 [95% CI, 0.60 to 3.39]; P = 0.42). Only nine Aboriginal and Torres Strait Islander patients provided 6-month health-related quality-of-life data. Conclusions: Aboriginal and Torres Strait Islander patients had reduced risk of death at 90 days when compared with non- Indigenous patients recruited to the ADRENAL trial at Royal Darwin Hospital, which was robust to adjustment for covariates, but similar outcomes when compared with a cohort matched for age, sex and severity of disease.

Objective: To compare the outcomes of patients with refractory out-of-hospital cardiac arrest (OHCA) transported to a hospital that provides extracorporeal membrane oxygenation (ECMO) during cardiopulmonary resuscitation (ECPR) with patients transported to hospitals without ECPR capability. Design, setting: Retrospective review of patient care records in a pre-hospital and hospital setting. Participants: Adult patients with OHCA who left the scene and arrived with cardiopulmonary resuscitation in progress at 16 hospitals in Melbourne, Australia, between January 2016 and December 2019. ⋯ After adjustment for baseline differences, the odds ratio for good neurological outcome after transport to an ECPR centre compared with a non-ECPR centre was 4.63 (95% CI, 0.97-22.11; P = 0.055). Conclusion: The survival rate of patients with refractory OHCA transported to an ECPR centre remains low. Outcomes in larger cities might be improved with shorter scene times and additional ECPR centres that would provide for earlier initiation of ECMO.

Background: The best way to offer non-invasive respiratory support across several aetiologies of acute respiratory failure (ARF) is presently unclear. Both high flow nasal catheter (HFNC) therapy and non-invasive positive pressure ventilation (NIPPV) may improve outcomes in critically ill patients by avoiding the need for invasive mechanical ventilation (IMV). Objective: Describe the details of the protocol and statistical analysis plan designed to test whether HFNC therapy is non-inferior or even superior to NIPPV in patients with ARF due to different aetiologies. ⋯ Results and conclusions: RENOVATE is designed to provide evidence on whether HFNC therapy improves, compared with NIPPV, important patient-centred outcomes in different aetiologies of ARF. Here, we describe the rationale, design and status of the trial. Trial registration:ClinicalTrials.gov NCT03643939.

Objectives: Mechanically ventilated patients account for about one-third of all admissions to the intensive care unit (ICU). Ketamine has been conditionally recommended to aid with analgesia in such patients, with low quality of evidence available to support this recommendation. We aimed to perform a narrative scoping review of the current knowledge of the use of ketamine, with a specific focus on mechanically ventilated ICU patients. ⋯ Conclusions: Ketamine is used in mechanically ventilated ICU patients with several potentially positive clinical effects. However, it has a significant side effect profile, which may limit its use in these patients. The role of low dose ketamine infusion in mechanically ventilated ICU patients is not well studied and requires investigation in high quality, prospective randomised trials.
