Aim: The Intensive Care Unit Randomised Trial Comparing Two Approaches to Oxygen Therapy Trial (ICU-ROX) compared conservative oxygen therapy with usual care in mechanically ventilated adults in Australian and New Zealand intensive care units. Dissemination focused on publication and presentation, with no targeted approach. The current study aimed to investigate whether health practitioners from intensive care units that participated in ICU-ROX were more likely to report they knew the trial results and had read the publication than those from intensive care units that did not participate; explore whether there was a difference between doctors' and nurses' knowledge of the ICU-ROX results and whether they read the publication.

Importance: Proton pump inhibitors (PPIs) or histamine-2 receptor blockers (H2RBs) are often prescribed for patients as stress ulcer prophylaxis drugs in the intensive care unit (ICU). The comparative effect of these drugs on mortality is unknown.

Objective: To compare in-hospital mortality rates using PPIs vs H2RBs for stress ulcer prophylaxis.

Purpose: It is unknown whether protocols targeting systematic prevention and treatment of fever achieve lower mean body temperature than usual care in intensive care unit (ICU) patients. The objective of the Randomised Evaluation of Active Control of temperature vs. ORdinary temperature management trial was to confirm the feasibility of such a protocol with a view to conducting a larger trial.

Background: The balance of risks and benefits with using proton pump inhibitors (PPIs) versus histamine-2 receptor blockers (HRB) for stress ulcer prophylaxis in patients who are invasively ventilated in the intensive care unit (ICU) is uncertain.

Objective: To describe the study protocol and statistical analysis plan for the Proton Pump Inhibitors versus Histamine-2 Receptor Blockers for Ulcer Prophylaxis Therapy in the Intensive Care Unit (PEPTIC) study.

Design, Setting And Participants: Protocol for a prospective, multicentre, randomised, open-label, cluster crossover, registry-embedded trial to be conducted in 50 ICUs in Australia, Canada, Ireland, New Zealand and the United Kingdom.

Background: The balance of risks and benefits of conservative v standard care oxygen strategies for patients who are invasively ventilated in the intensive care unit (ICU) is uncertain.

Objective: To describe the study protocol and statistical analysis plan for the ICU randomised trial comparing two approaches to oxygen therapy (ICU-ROX).

Design, Setting And Participants: Protocol for a multicentre, randomised, participant and outcome assessor-blinded, standard care-controlled, parallel-group, two-sided superiority trial to be conducted in up to 22 ICUs in Australia and New Zealand.

Objective: The objective of the intensive care unit randomised trial comparing two approaches to oxygen therapy (ICU-ROX) pilot phase, which included the first 100 patients of an overall sample of 1000, was to examine feasibility.

Design: Investigator-initiated, prospective, parallel-group, pilot randomised controlled trial.

Setting: Six medical-surgical intensive care units (ICUs) in Australia and New Zealand, with participants recruited from September 2015 through June 2016.

Objective: To evaluate the effect of Plasma-Lyte 148 (PL-148) compared with 0.9% saline (saline) on blood product use and postoperative bleeding in patients admitted to the intensive care unit (ICU) following cardiac surgery.

Design: A post hoc subgroup analysis conducted within a multicenter, double-blind, cluster-randomized, double-crossover study (study 1) and a prospective, single-center nested-cohort study (study 2).

Background: Body temperature can be reduced in febrile patients in the intensive care unit using medicines and physical cooling devices, but it is not known whether systematically preventing and treating fever reduces body temperature compared with standard care.

Objective: To describe the study protocol and statistical analysis plan for the Randomised Evaluation of Active Control of Temperature versus Ordinary Temperature Management (REACTOR) trial.

Design, Setting And Participants: Protocol for a phase II, multicentre trial to be conducted in Australian and New Zealand ICUs admitting adult patients.

Background: 0.9% saline is the most commonly used intravenous (IV) fluid in the world but recent data raise the possibility that, compared with buffered crystalloid fluids such as Plasma-Lyte 148, the administration of 0.9% saline might increase the risk of developing acute kidney injury.

Objective: To identify intensive care patients dying within 2 years of discharge from hospital and assess whether the cause of death was related to the diagnosis at hospital discharge.

Design, Setting And Participants: A retrospective cohort study of all patients admitted to the intensive care unit at Wellington Hospital, New Zealand, between 1 July 2001 and 30 June 2003, using data from the ICU database. Mortality data were obtained from the New Zealand National Death Registry.
