Objectives: The Australasian Resuscitation in Sepsis Evaluation (ARISE) study researched septic shock treatment within EDs. This study aims to evaluate whether: (i) conduct of the ARISE study was associated with changes in epidemiology and care for adults (≥18 years) admitted from EDs to ICUs with sepsis in Australia and New Zealand; and (ii) such changes differed among 45 ARISE trial hospitals compared with 120 non‐trial hospitals. Methods: Retrospective study using interrupted time series analysis in three time periods; 'Pre‐ARISE' (January 1997 to December 2007), 'During ARISE' (January 2008 to May 2014) and 'Post‐ARISE' (June 2014 to December 2017) using data from the Australian and New Zealand Intensive Care Society Adult Patient Database. Results: Over 21 years there were 54 121 ICU admissions from the ED with sepsis; which increased from 8.1% to 16.4%; 54.6% male, median (interquartile range) age 66 (53–76) years. In the pre‐ARISE period, pre‐ICU ED length of stay (LOS) decreased in trial hospitals but increased in non‐trial hospitals (P = 0.174). During the ARISE study, pre‐ICU ED LOS declined more in trial hospitals (P = 0.039) as did the frequency of mechanical ventilation in the first 24 h (P = 0.003). However, ICU and hospital LOS, in‐hospital mortality and risk of death declined similarly in both trial and non‐trial hospitals. Conclusions: Sepsis‐related admissions increased from 8.1% to 16.4%. During the ARISE study, there was more rapid ICU admission and decreased early ventilation. However, these changes were not sustained nor associated with decreased risk of death or duration of hospitalisation. [ABSTRACT FROM AUTHOR]

Background: It is uncertain whether increases in PaCO2 during surgery lead to an increase in plasma potassium concentration and, if so, by how much. Hyperkalaemia may result in cardiac arrhythmias, muscle weakness or paralysis. The key objectives were to determine whether increases in PaCO2 during laparoscopic surgery induce increases in plasma potassium concentrations and, if so, to determine the magnitude of such changes.Methods: A retrospective observational study of adult patients undergoing laparoscopic abdominal surgery was perfomed. The independent association between increases in PaCO2 and changes in plasma potassium concentration was assessed by performing arterial blood gases within 15 min of induction of anaesthesia and within 15 min of completion of surgery.Results: 289 patients were studied (mean age of 63.2 years; 176 [60.9%] male, and mean body mass index of 29.3 kg/m2). At the completion of the surgery, PaCO2 had increased by 5.18 mmHg (95% CI 4.27 mmHg to 6.09 mmHg) compared to baseline values (P < 0.001) with an associated increase in potassium concentration of 0.25 mmol/L (95% CI 0.20 mmol/L to 0.31 mmol/L, P < 0.001). On multiple regression analysis, PaCO2 changes significantly predicted immediate changes in plasma potassium concentration and could account for 33.1% of the variance (r2 = 0.331, f(3,259) = 38.915, P < 0.001). For each 10 mmHg increment of PaCO2 the plasma potassium concentration increased by 0.18 mmol/L.Conclusion: In patients receiving laparoscopic abdominal surgery, there is an increase in PaCO2 at the end of surgery, which is independently associated with an increase in plasma potassium concentration. However, this effect is small and is mostly influenced by intravenous fluid therapy (Plasma-Lyte 148 solution) and the presence of diabetes. Trial registration Retrospectively registered in the Australian New Zealand Clinical Trials Registry (Trial Number: ACTRN12619000716167). [ABSTRACT FROM AUTHOR]- Published

The Medical Emergency Team (MET) has enhanced the recognition and response to clinical deterioration in acute healthcare. However, patients reviewed by the MET are at increased risk of in-hospital death. Identifying patients at risk of deterioration may improve patient outcomes. To identify patient demographic, medical characteristics and healthcare systems and processes at the time of admission (baseline), associated with Medical Emergency Team (MET) review within 48 h (MET-48 h) of admission. Single-site, year-long, retrospective cohort comprising patients admitted for at least 24 h, using routinely collected hospital data. A three-stage modelling approach was used to identify baseline factors associated with MET-48 h The study included 15,695 patients with mean age 62.1 years (SD 19.6), male (53.5%), born in Australia or New Zealand (60.9%) and 51.6% held a low-income concession card. A total of 4.3% of patients received a MET review within 48 h of admission. Variables independently associated with MET-48 h in a fully adjusted logistic model included age of 80 years or more (OR = 1.37); ≥3 previous emergency admissions (OR = 1.59); Charlson Comorbidity Index 1 or 2 (OR = 1.47), or ≥ 3 (OR = 1.99); history of alcohol-related behaviour concerns (OR = 2.04), chronic heart failure (OR = 1.48); chronic obstructive pulmonary disease (OR = 1.35); admission for colorectal (OR = 2.66) or upper gastro-intestinal (OR = 1.94) surgery, respiratory or tracheostomy (OR = 2.24); immunology and infections (OR = 1.90); emergency admission (OR = 1.36); admission at night (OR = 1.74), or summer (OR = 1.41) This is the first study to demonstrate the potential to predict clinical deterioration using data that is readily accessible at the time of admission to hospital. • At admission, patient diagnosis, comorbidities are associated with later MET review. • Charlson Score 1–2 or ≥ 3; 3+ prior emergency admissions; are important risk factors. • MET risk double in admissions for colorectal, respiratory, upper GI or infection. • Health system factors including time or season of admission associated with MET. • Associations similar for MET within 48 or 72 h of admission.

Objectives: To evaluate what proportion of unplanned ICU admissions from hospital wards occurred after rapid response team review and compare baseline characteristics and outcomes of patients admitted after rapid response team review with non-rapid response team-related admissions.Design: Multicenter binational retrospective cohort study.Setting: One-hundred seventy-eight ICUs across Australia and New Zealand.Patients: All adults (≥ 17 yr) in the Australian and New Zealand Intensive Care Society Adult Patient Database between 2012 and 2017.Interventions: None.Measurements and Main Results: Among 97,181 unplanned ICU admissions from the ward, prior rapid response team review occurred in 55,084 cases (56.7%). Rapid response team patients were slightly older (65.4 [16.9] vs 63.3 [18]), had a higher Acute Physiology and Chronic Health Evaluation III score (64.6 [27.1] vs 54.7 [25.3]) and more frequently had limitations of medical treatment (13.1% vs 8.5%) compared with patients with no rapid response team review. The strongest independent associations with ICU admission following rapid response team review included age, ICU admission diagnosis (especially sepsis-, neurologic-, respiratory-, and cardiovascular-related), tertiary ICU status, and presence of limitations of medical treatment (p < 0.0001 all comparisons). Rapid response team-related ICU admissions had a longer median ICU (2.4 d [1.2-4.6 d] vs 2.1 d [1.0-4.2 d]) and hospital (12.8 d [7.0-23.6 d] vs 10.8 d [5.9-20.3 d]) length of stay, and were more likely to die in the ICU (12.3% vs 7.5%) and in-hospital (20.8% vs 13.5%) (p < 0.0001). After adjusting for illness severity and institution, patients admitted following rapid response team review stayed longer in hospital but were not at increased risk of dying in-hospital (adjusted odds ratio, 1.03; 0.98-1.07).Conclusions: In Australia and New Zealand, hospital ward patients admitted to ICU following rapid response team review represent the majority of ward-based ICU admissions, are more chronically and acutely ill, and more frequently have sepsis than those admitted from the ward without rapid response team review. Their unadjusted outcomes are worse, but after adjustment their mortality is similar. [ABSTRACT FROM AUTHOR]- Published

Abstract: Aim: Determine current resuscitation practices and outcomes in patients presenting to the emergency department (ED) with sepsis and hypoperfusion or septic shock in Australia and New Zealand (ANZ). Methods: Three-month prospective, multi-centre, observational study of all adult patients with sepsis and hypoperfusion or septic shock in the ED of 32 ANZ tertiary-referral, metropolitan and rural hospitals. Results: 324 patients were enrolled (mean [SD] age 63.4 [19.2] years, APACHE II score 19.0 [8.2], 52.5% male). Pneumonia (n =138/324, 42.6%) and urinary tract infection (n =98/324, 30.2%) were the commonest sources of sepsis. Between ED presentation and 6hours post-enrolment (T6hrs), 44.4% (n =144/324) of patients received an intra-arterial catheter, 37% (n =120/324) a central venous catheter and 0% (n =0/324) a continuous central venous oxygen saturation (ScvO2) catheter. Between enrolment and T6hrs, 32.1% (n =104/324) received a vasopressor infusion, 7.4% (n =24/324) a red blood cell transfusion, 2.5% (n =8/324) a dobutamine infusion and 18.5% (n =60/324) invasive mechanical ventilation. Twenty patients (6.2%) were transferred from ED directly to the operating theatre, 36.4% (n =118/324) were admitted directly to ICU, 1.2% (n =4/324) died in the ED and 56.2% (n =182/324) were transferred to the hospital floor. Overall ICU admission rate was 52.4% (n =170/324). ICU and overall in-hospital mortality were 18.8% (n =32/170) and 23.1% (n =75/324) respectively. In-hospital mortality was not different between patients admitted to ICU (24.7%, n =42/170) and the hospital floor (21.4%, n =33/154). Conclusions: Management of ANZ patients presenting to ED with sepsis does not routinely include protocolised, ScvO2-directed resuscitation. In-hospital mortality compares favourably with reported mortality in international sepsis trials and nationwide surveys of resuscitation practices. [Copyright &y& Elsevier]

- Abstract
Background: We recently reported the results for a large randomized controlled trial of low tidal volume ventilation (LTVV) versus conventional tidal volume (CTVV) during major surgery when positive end expiratory pressure (PEEP) was equal between groups. We found no difference in postoperative pulmonary complications (PPCs) in patients who received LTVV. However, in the subgroup of patients undergoing laparoscopic surgery, LTVV was associated with a numerically lower rate of PPCs after surgery. We aimed to further assess the relationship between LTVV versus CTVV during laparoscopic surgery., Methods: We conducted a post-hoc analysis of this pre-specified subgroup. All patients received volume-controlled ventilation with an applied PEEP of 5 cmH
2 O and either LTVV (6 mL/kg predicted body weight [PBW]) or CTVV (10 mL/kg PBW). The primary outcome was the incidence of a composite of PPCs within seven days., Results: Three hundred twenty-eight patients (27.2%) underwent laparoscopic surgeries, with 158 (48.2%) randomised to LTVV. Fifty two of 157 patients (33.1%) assigned to LTVV and 72 of 169 (42.6%) assigned to conventional tidal volume developed PPCs within 7 days (unadjusted absolute difference, - 9.48 [95% CI, - 19.86 to 1.05]; p = 0.076). After adjusting for pre-specified confounders, the LTVV group had a lower incidence of the primary outcome than patients receiving CTVV (adjusted absolute difference, - 10.36 [95% CI, - 20.52 to - 0.20]; p = 0.046)., Conclusion: In this post-hoc analysis of a large, randomised trial of LTVV we found that during laparoscopic surgeries, LTVV was associated with a significantly reduced PPCs compared to CTVV when PEEP was applied equally between both groups., Trial Registration: Australian and New Zealand Clinical Trials Registry no: 12614000790640., (© 2023.

- Abstract
Background: The NSW Clinical Excellence commission introduced the 'Between the Flags' programme, in response to the death of a young patient, as a system-wide approach for early detection and management of the deteriorating patient in all NSW hospitals. The impact of BTF implementation on the 35 larger hospitals with intensive care units (ICU) has not been reported previously., Aim: To assess the impact of 'Between the Flags' (BTF), a two-tier rapid response system across 35 hospitals with an ICU in NSW, on the incidence of in-hospital cardiac arrests and the incidence and outcome of patients admitted to an ICU following cardiac arrest and rapid response team activation., Methods: This is a prospective observational study of the BTF registry (August 2010 to June 2016) and the Australian and New Zealand Intensive Care Society Adult Patient Database (January 2008 to December 2016) in 35 New South Wales public hospitals with an ICU. The primary outcome studied was the proportion of in-hospital cardiac arrests. Secondary outcomes included changes in the severity of illness and outcomes of cardiac arrest admissions to the ICU and changes in the volume of rapid response calls., Results: The cardiac arrest rate per 1000 hospital admissions declined from 0.91 in the implementation period to 0.70. Propensity score analysis showed significant declines in ICU and hospital mortality and length of stay for cardiac arrest patients admitted to the ICU (all P < 0.001)., Conclusions: The BTF programme was associated with a significant reduction in cardiac arrests in hospitals and ICU admissions secondary to cardiac arrests in 35 NSW hospitals with an ICU., (© 2020 Royal Australasian College of Physicians.)

- Abstract
Background: Improving the timely recognition and response to clinical deterioration is a critical challenge for clinicians, educators, administrators and researchers. Clinical deterioration leading to Rapid Response Team review is associated with poor patient outcomes. A range of factors associated with clinical deterioration and its outcomes have been identified, and may help with early identification of deteriorating patients. However, the relative importance of each factor on the development of clinical deterioration is unknown., Objective: To identify the relative importance of factors contributing to the development of clinical deterioration in ward patients, as perceived by health professionals who have experience in recognising or responding to clinical deterioration, or in the management, administration or governance of RRSs., Methods: A written questionnaire containing 12 pre-determined factors was provided to participants. Participants were asked to rank the items from most to least important contributors to ward patient deterioration. The study took place during a session of the Australia and New Zealand Intensive Care Society Rapid Response Team conference., Results: A final sample of 233 (83% response rate), returned the questionnaire. The sample comprised specialist ICU registered nurses with direct patient contact (64%), ICU consultant doctors (17%), ICU nurse managers (7%), hospital administrators (2%), ICU registrars (2%), quality coordinators (2%) and non-hospital staff (4%). The patient's presenting illness/main diagnosis was the highest ranked factor, followed by pre-existing co-morbidities, seniority of nursing ward staff, medical documentation, senior medical staff, and interdisciplinary communication. Almost two-thirds of participants ranked patient characteristics as the most important contributor to clinical deterioration., Conclusion: Health professionals who have experience in recognising or responding to clinical deterioration, or in the management, administration or governance of RRSs perceive that patient characteristics such as the patient's primary diagnosis and comorbidities to be the most important contributors to clinical deterioration., (Crown Copyright © 2017.

- Abstract
Context: The novel influenza A(H1N1) pandemic affected Australia and New Zealand during the 2009 southern hemisphere winter. It caused an epidemic of critical illness and some patients developed severe acute respiratory distress syndrome (ARDS) and were treated with extracorporeal membrane oxygenation (ECMO)., Objectives: To describe the characteristics of all patients with 2009 influenza A(H1N1)-associated ARDS treated with ECMO and to report incidence, resource utilization, and patient outcomes., Design, Setting, and Patients: An observational study of all patients (n = 68) with 2009 influenza A(H1N1)-associated ARDS treated with ECMO in 15 intensive care units (ICUs) in Australia and New Zealand between June 1 and August 31, 2009., Main Outcome Measures: Incidence, clinical features, degree of pulmonary dysfunction, technical characteristics, duration of ECMO, complications, and survival., Results: Sixty-eight patients with severe influenza-associated ARDS were treated with ECMO, of whom 61 had either confirmed 2009 influenza A(H1N1) (n = 53) or influenza A not subtyped (n = 8), representing an incidence rate of 2.6 ECMO cases per million population. An additional 133 patients with influenza A received mechanical ventilation but no ECMO in the same ICUs. The 68 patients who received ECMO had a median (interquartile range [IQR]) age of 34.4 (26.6-43.1) years and 34 patients (50%) were men. Before ECMO, patients had severe respiratory failure despite advanced mechanical ventilatory support with a median (IQR) Pao(2)/fraction of inspired oxygen (Fio(2)) ratio of 56 (48-63), positive end-expiratory pressure of 18 (15-20) cm H(2)O, and an acute lung injury score of 3.8 (3.5-4.0). The median (IQR) duration of ECMO support was 10 (7-15) days. At the time of reporting, 48 of the 68 patients (71%; 95% confidence interval [CI], 60%-82%) had survived to ICU discharge, of whom 32 had survived to hospital discharge and 16 remained as hospital inpatients. Fourteen patients (21%; 95% CI, 11%-30%) had died and 6 remained in the ICU, 2 of whom were still receiving ECMO., Conclusions: During June to August 2009 in Australia and New Zealand, the ICUs at regional referral centers provided mechanical ventilation for many patients with 2009 influenza A(H1N1)-associated respiratory failure, one-third of whom received ECMO. These ECMO-treated patients were often young adults with severe hypoxemia and had a 21% mortality rate at the end of the study period.

- Abstract
Background: An epidemiologic profile of traumatic brain injury (TBI) in Australia and New Zealand was obtained following the publication of international evidence-based guidelines., Methods: Adult patients with TBI admitted to the intensive care units (ICU) of major trauma centers were studied in a 6-month prospective inception cohort study. Data including mechanisms of injury, prehospital interventions, secondary insults, operative and intensive care management, and outcome assessments 12-months postinjury were collected., Results: There were 635 patients recruited from 16 centers. The mean (+/-SD) age was 41.6 years +/- 19.6 years; 74.2% were men; 61.4% were due to vehicular trauma, 24.9% were falls in elderly patients, and 57.2% had severe TBI (Glasgow Coma Scale score =8). Secondary brain insults were recorded in 28.5% and 34.8% underwent neurosurgical procedures before ICU admission. There was concordance with TBI and ICU practice guidelines, although intracranial pressure monitoring was used in 44.5% patients with severe TBI. Twelve-month mortality was 26.9% in all patients and 35.1% in patients with severe TBI. Favorable outcomes at 12 months were recorded in 58.8% of all patients and in 48.5% of patients with severe TBI., Conclusions: In Australia and New Zealand, mortality and favorable neurologic outcomes after TBI were similar to published data before the advent of evidence-based guidelines. A high incidence of prehospital secondary brain insults and an ageing population may have contributed to these outcomes. Strategies to improve outcomes from TBI should be directed at preventive public health strategies and interventions to minimize secondary brain injuries in the prehospital period.

- Abstract
Introduction: Information about Medical Emergency Teams (METs) in Australia and New Zealand (ANZ) is limited to local studies and a cluster randomised controlled trial (the Medical Emergency Response and Intervention Trial [MERIT]). Thus, we sought to describe the timing of the introduction of METs into ANZ hospitals relative to relevant publications and to assess changes in the incidence and rate of intensive care unit (ICU) admissions due to a ward cardiac arrest (CA) and ICU readmissions., Methods: We used the Australian and New Zealand Intensive Care Society database to obtain the study data. We related MET introduction to publications about adverse events and MET services. We compared the incidence and rate of readmissions and admitted CAs from wards before and after the introduction of an MET. Finally, we identified hospitals without an MET system which had contributed to the database for at least two years from 2002 to 2005 and measured the incidence of adverse events from the first year of contribution to the second., Results: The MET status was known for 131 of the 172 (76.2%) hospitals that did not participate in the MERIT study. Among these hospitals, 110 (64.1%) had introduced an MET service by 2005. In the 79 hospitals in which the MET commencement date was known, 75% had introduced an MET by May 2002. Of the 110 hospitals in which an MET service was introduced, 24 (21.8%) contributed continuous data in the year before and after the known commencement date. In these hospitals, the mean incidence of CAs admitted to the ICU from the wards changed from 6.33 per year before to 5.04 per year in the year after the MET service began (difference of 1.29 per year, 95% confidence interval [CI] -0.09 to 2.67; P = 0.0244). The incidence of ICU readmissions and the mortality for both ICU-admitted CAs from wards and ICU readmissions did not change. Data were available to calculate the change in ICU admissions due to ward CAs for 16 of 62 (25.8%) hospitals without an MET system. In these hospitals, admissions to the ICU after a ward CA decreased from 5.0 per year in the first year of data contribution to 4.2 per year in the following year (difference of 0.8 per year, 95% CI -0.81 to 3.49; P = 0.3)., Conclusion: Approximately 60% of hospitals in ANZ with an ICU report having an MET service. Most introduced the MET service early and in association with literature related to adverse events. Although available in only a quarter of hospitals, temporal trends suggest an overall decrease in the incidence of ward CAs admitted to the ICU in MET as well as non-MET hospitals.

- Abstract
Over the past 12 years, the Australian and New Zealand Intensive Care Society (ANZICS) Clinical Trials Group and the broader intensive care community in Australia and New Zealand have established a track record for conducting high quality, investigator-initiated clinical research in critically ill patients. This is highlighted by the publication of the SAFE (Saline Albumin Fluid Evaluation) study in the New England Journal of Medicine and the MERIT (Medical Early Response Intervention and Therapy) study in the Lancet. Here, we discuss potential impediments to the further advancement of intensive care research in Australia and New Zealand, and suggest strategies to address them. We propose that there is a need to broaden the current research scope and develop more multifaceted research programs that address clinically important issues. We stress the need to also undertake phase II studies to assess safety, pharmacokinetics and biological plausibility of new and established therapies. In addition, we highlight limitations imposed by the relatively small regional population of Australia and New Zealand, and the need to develop international collaborations to allow trials requiring large sample sizes. We contend that the best chance of improving outcomes in many disease states requires studies to commence before patients enter the ICU, which will depend on collaboration with established and emerging craft groups, such as ambulance services, emergency medicine and anaesthesia. We also emphasise the need to study system factors affecting patient outcomes, as well as the translation of research findings into clinical practice. Finally, we describe the establishment and objectives of the Australian and New Zealand Intensive Care Research Centre (ANZIC-RC) and outline the Centre's current projects in the context of an integrated research framework.
