Objective: Intensive care (ICU) beds are scarce and decision-making regarding admission is complex and multi-factorial. This study aimed to characterise differences in admission decision making between Australia and New Zealand and compare to previous data to establish changes over time.

Design: Online Survey.

Setting And Participants: An online survey was distributed to Australian and New Zealand intensive care doctors measuring triage behaviours in the last week and responses to ICU triage scenarios.

Main Outcome Measures: Perceived ICU admission behaviours.

Results: 103 responses were obtained, 83(80.6%) from Australia and 97 (94.2%) from specialist intensivists. The median number of triage decisions and patients declined were 6-10 and 1-5 respectively. No difference was noted in the role of ICU bed capacity in decision making between Australia and New Zealand. Compared to Australian intensivists, New Zealand intensivists were less likely to admit a patient: with relapsed acute myeloid leukaemia (AML) and acute respiratory distress syndrome (ARDS)(p=0.03), with persistent vegetative state and community acquired (p=0.02) or iatrogenic (p=0.03) pneumonia. Compared to respondents in 2009 (n=238), 2023 respondents were more likely to admit a patient: with a severe intracranial bleed who may become braindead (p=0.005), with relapsed AML and ARDS (p=0.02), with stroke for palliative care (p<0.001); and less likely to admit a patient with persistent vegetative state and iatrogenic pneumonia (p=0.03). In a multivariable analysis, respondents from Australian compared to New Zealand and from 2023 compared to 2009 were more likely to indicate they would admit patients to the ICU in the scenarios described (p<0.001 for both comparisons).

Conclusions: Our study suggests that New Zealand intensivists may apply more restrictive ICU admission criteria than Australian intensivists. Changes in attitudes to admission since 2009 may reflect increased awareness of the importance of facilitating organ donation and the role of ICU as providers of palliative care.

Background: Monitoring vital signs in hospitalized patients is crucial for evaluating their clinical condition. While early warning scores like the modified early warning score (MEWS) are typically calculated 3 to 4 times daily through spot checks, they might not promptly identify early deterioration. Leveraging technologies that provide continuous monitoring of vital signs, combined with an early warning system, has the potential to identify clinical deterioration sooner.
