Multicenter Study
Sodium administration in critically ill patients in Australia and New Zealand: a multicentre point prevalence study.
Inadvertent sodium administration in excess of recommended daily requirements has been reported during routine care of critically ill patients. ⋯ This point prevalence study suggests that sodium administration in excess of recommended daily requirements may be common in Australia and New Zealand ICUs. The main sodium source was IV maintenance fluids, followed by fluid boluses and drug boluses.

Despite extensive work to improve early recognition of and response to abnormal vital signs, a failure or delay in response to clinical deterioration by activating a medical emergency team (MET) can affect patient safety. ⋯ Despite one in seven patients fulfilling MET criteria, MET activation occurred infrequently. The presence of MET criteria was associated with a doubling of the hospital LOS. Escalation of care in response to detection of MET criteria fulfillment was variable. Further research tracking patient management is needed to understand the decision-making process that occurs in the presence of clinical deterioration.

Near-infrared spectroscopy of the thenar eminence (NIRSth) can be used at the bedside to assess tissue oxygenation (StO2), the reperfusion response to ischaemia and the tissue haemoglobin index (THI). Its ability to estimate forearm blood flow (FBF) has not previously been assessed. ⋯ NIRSth can be used to estimate FBF. Given its portability and its ability to also measure StO2 and vascular reactivity, NIRSth can assist in providing a comprehensive bedside assessment of the forearm circulation in critically ill patients.

To develop a comprehensive set of items describing physiotherapy mobilisation practices for critically ill patients, and to document current practices in intensive care units in Australia and New Zealand, focusing on patients having > 48 hours of mechanical ventilation. ⋯ Patient mobilisation was shown to be low in a single-day point prevalence study. Future observational studies are required to confirm the results.

Observational Study
Intensive care unit occupancy after introduction of the emergency department 4-hour discharge rule at a tertiary referral hospital in Western Australia.
The 4-hour rule has been introduced in Western Australia, requiring that emergency department (ED) patients be admitted to hospital or discharged from the ED within 4 hours of presentation. We hypothesised that this rule might have been associated with changes in medical emergency team (MET) calls and intensive care unit exit bed block. ⋯ The introduction of the 4-hour rule was associated with increased exit block from the ICU, but not with increased MET calls to attend to unstable or deteriorating ward patients. Introduction of the 4-hour rule was associated with a small reduction in hospital mortality.
