Crit Care Resusc

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 describe the prevalence of common and clinically relevant microbial isolates before and after the migration of a 24-bed, open plan, adult intensive care unit (ICU) to a new extended design of 32 single rooms, supporting an expanded clinical oncology casemix while continuing all existing clinical services. Design: Retrospective, observational descriptive analysis covering the period 5 May 2014 to 4 May 2018 - the 2 years before and after the ICU relocation on 5 May 2016. Setting: A university-associated, tertiary teaching hospital and state trauma centre in Victoria, Australia. ⋯ The incidence rates per 1000 occupied bed-days between ICU locations were unchanged for Staphylococcus aureus (IRR, 1.1; 95% CI, 0.91-1.3), extended-spectrum beta-lactamase-producing organisms (IRR, 1.4; 95% CI, 0.78-2.6) and carbapenemase-producing Enterobacterales (IRR, 0.85; 95% CI, 0.11-6.4). Conclusion: Within the limits of a before-after design and clinically directed sampling, relocation to a new ICU with single rooms and a growing oncological patient casemix was accompanied by no overall change in the apparent prevalence of the nosocomial pathogens S. aureus, extended-spectrum beta-lactamase-producing organisms or carbapenemase-producing Enterobacterales. These finding suggest that advanced physical infrastructure, including patient accommodation in single rooms, may play a role in overall safe delivery of critical care.

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.

Background: With the adoption of multimodal neuromonitoring techniques, a large amount of high resolution neurophysiological data is generated during the treatment of patients with moderate to severe traumatic brain injury (m-sTBI) that is available for further analysis. The Monitoring with Advanced Sensors, Transmission and E-Resuscitation in Traumatic Brain Injury (MASTER-TBI) collaborative was formed in 2020 to facilitate analysis of these data. Objective: The MASTER-TBI collaborative curates m-sTBI patient data for the purposes of comparative effectiveness research, machine learning algorithm development, and neuropathophysiological phenomena analysis. ⋯ Results and conclusion: MASTER-TBI continues to develop data science-informed systems and techniques to maximise the use of captured high resolution m-sTBI patient neuromonitoring data. The highly innovative systems provide a world-class platform which aims to enhance the search for improved m-sTBI care and outcomes. This article provides an overview of the MASTER-TBI project's developed systems and techniques as well as a rationale for the approaches taken.

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.
