Abstract
BACKGROUND Infusion sets (comprising the tubing, measuring burettes, fluid containers, transducers) that are connected to invasive vascular devices are changed on a regular basis in an effort to reduce bacterial colonisation and bloodstream infection. There is a balance between reducing infection and creating unnecessary waste. Current evidence suggests that for central venous catheters (CVCs), changing infusion sets at 7 days does not increase infection risks. OBJECTIVES The objective of this study was to describe the current unit guidelines in Australian and New Zealand intensive care units (ICUs) for changing infusion sets for CVCs. METHODS prospective cross-sectional point prevalence study, as a part of the 2021 Australian and New Zealand Intensive Care Society Point Prevalence Program. PARTICIPANTS Australia and New Zealand (ANZ) adult ICUs and their patients on the day of the study. RESULTS Data were collected from 51 ICUs across ANZ. One-third of these (16/49) ICUs had a guideline that specified a 7-day replacement period, with the rest having a more frequent replacement period. CONCLUSION Most ICUs participating in this survey had policies to change their CVC infusion tubing in 3-4 days, and recent high-level evidence supports an update to extend this to 7 days. There remains work to be done to spread this evidence to ANZ ICUs and improve environmental sustainability initiatives.

Abstract
BACKGROUND The REVISE (Re-Evaluating the Inhibition of Stress Erosions in the ICU) trial will evaluate the impact of the proton pump inhibitor pantoprazole compared to placebo in invasively ventilated critically ill patients. OBJECTIVE To outline the statistical analysis plan for the REVISE trial. METHODS REVISE is a randomized clinical trial ongoing in intensive care units (ICUs) internationally. Patients ≥ 18 years old, receiving invasive mechanical ventilation, and expected to remain ventilated beyond the calendar day after randomization are allocated to either 40 mg pantoprazole intravenously or placebo while mechanically ventilated. RESULTS The primary efficacy outcome is clinically important upper GI bleeding; the primary safety outcome is 90-day mortality. Secondary outcomes are ventilator-associated pneumonia, Clostridioides difficile infection, new renal replacement therapy, ICU and hospital mortality, and patient-important GI bleeding. Tertiary outcomes are total red blood cells transfused, peak serum creatinine concentration, and duration of mechanical ventilation, ICU, and hospital length of stay. Following an interim analysis of results from 2400 patients (50% of 4800 target sample size), the data monitoring committee recommended continuing enrolment. CONCLUSIONS This statistical analysis plan outlines the statistical analyses of all outcomes, sensitivity analyses, and subgroup analyses. REVISE will inform clinical practice and guidelines worldwide. TRIAL REGISTRATION www. CLINICALTRIALS gov NCT03374800. November 21, 2017.

Abstract
OBJECTIVE Optimal resuscitation of sepsis-induced hypotension is uncertain, particularly the role of restrictive fluid strategies, leading to variability in usual practice. The objective of this study is to understand resuscitation practices in patients presenting to ED with early sepsis. METHODS Design, participants and setting: Prospective, observational, multicentre, single-day, point-prevalence study enrolling adult patients present in 51 Australian and New Zealand ICUs at 10.00 hours, 8 June 2021. MAIN OUTCOME MEASURES Site-level data on sepsis policies and patient-level demographic data, presence of sepsis and fluid and vasopressor administration in the first 24 h post-ED presentation. RESULTS A total of 722 patients were enrolled. ED was the ICU admission source for 222 of 722 patients (31.2%) and 78 of 222 patients (35%) met the criteria for sepsis within 24 h of ED presentation. Median age of the sepsis cohort was 61 (48-72) years, 58% were male and respiratory infection was the commonest cause (53.8%). The sepsis cohort had a higher severity of illness than the non-sepsis cohort (144/222 patients) and chronic immunocompromise was more common. Of 78 sepsis patients, 55 (71%) received ≥1 fluid boluses with 500 and 1000 mL boluses equally common (both 49%). In the first 24 h, 2335 (1409-3125) mL (25.3 [13.2-42.9] mL/kg) was administered. Vasopressors were administered in 53 of 78 patients (68%) and for 25 patients (47%) administration was peripheral. CONCLUSIONS ICU patients presenting to the ED with sepsis receive less fluids than current international recommendations and peripheral vasopressor administration is common. This finding supports the conduct of clinical trials evaluating optimal fluid dose and vasopressor timing for early sepsis-induced hypotension.

Abstract
Objective To describe current transfusion practices in intensive care units (ICUs) in Australia and New Zealand, compare them against national guidelines, and describe how viscoelastic haemostatic assays (VHAs) are used in guiding transfusion decisions. Design setting and participants Prospective, multicentre, binational point-prevalence study. All adult patients admitted to participating ICUs on a single day in 2021. Main outcome measures Transfusion types, amounts, clinical reasons, and triggers; use of anti-platelet medications, anti-coagulation, and VHA. Results Of 712 adult patients in 51 ICUs, 71 (10%) patients received a transfusion during the 24hr period of observation. Compared to patients not transfused, these patients had higher Acute Physiology and Chronic Health Evaluation II scores (19 versus 17, p = 0.02), a greater proportion were mechanically ventilated (49.3% versus 37.3%, p < 0.05), and more had systemic inflammatory response syndrome (70.4% versus 51.3%, p < 0.01). Overall, 63 (8.8%) patients received red blood cell (RBC) transfusions, 10 (1.4%) patients received platelet transfusions, 6 (0.8%) patients received fresh frozen plasma (FFP), and 5 (0.7%) patients received cryoprecipitate. VHA was available in 42 (82.4%) sites but only used in 6.6% of transfusion episodes when available. Alignment with guidelines was found for 98.6% of RBC transfusions, but only 61.6% for platelet, 28.6% for FFP, and 20% for cryoprecipitate transfusions. Conclusions Non-RBC transfusion decisions are often not aligned with guidelines and VHA is commonly available but rarely used to guide transfusions. Better evidence to guide transfusions in ICUs is needed.

Abstract
INTRODUCTION The Re-Evaluating the Inhibition of Stress Erosions (REVISE) Trial aims to determine the impact of the proton pump inhibitor pantoprazole compared with placebo on clinically important upper gastrointestinal (GI) bleeding in the intensive care unit (ICU), 90-day mortality and other endpoints in critically ill adults. The objective of this report is to describe the rationale, methodology, ethics and management of REVISE. METHODS AND ANALYSIS REVISE is an international, randomised, concealed, stratified, blinded parallel-group individual patient trial being conducted in ICUs in Canada, Australia, Saudi Arabia, UK, US, Kuwait, Pakistan and Brazil. Patients≥18 years old expected to remain invasively mechanically ventilated beyond the calendar day after enrolment are being randomised to either 40 mg pantoprazole intravenously or an identical placebo daily while mechanically ventilated in the ICU. The primary efficacy outcome is clinically important upper GI bleeding within 90 days of randomisation. The primary safety outcome is 90-day all-cause mortality. Secondary outcomes include rates of ventilator-associated pneumonia, Clostridioides difficile infection, new renal replacement therapy, ICU and hospital mortality, and patient-important GI bleeding. Tertiary outcomes are total red blood cells transfused, peak serum creatinine level in the ICU, and duration of mechanical ventilation, ICU and hospital stay. The sample size is 4800 patients; one interim analysis was conducted after 2400 patients had complete 90-day follow-up; the Data Monitoring Committee recommended continuing the trial.

Abstract
BACKGROUND Patient communication is profoundly impacted during the intensive care unit (ICU) stay. While the impacts of altered communication are recognised, there is a paucity of data on the prevalence of communication attempts as well as modes utilised by patients and unit practices to manage communication function. OBJECTIVE The objectives of this study were to describe the prevalence and characteristics of observed communication attempts (nonverbal, verbal, and use of the staff call bell) in adult ICU patients and report on unit-level practices on communication management. METHODS A prospective, binational, cross-sectional point-prevalence study was conducted across 44 Australia and New Zealand adult ICUs. Data on communication attempts, modes, ICU-level guidelines, training, and resources were collected in June 2019. RESULTS Across 44 ICUs, 470 of 623 (75%) participants, including ventilated and nonventilated patients, were attempting to communicate on the study day. Of those invasively ventilated via an endotracheal tube for the entire study day, 42 of 172 (24%) were attempting to communicate and 39 of 45 (87%) patients with a tracheostomy were attempting to communicate. Across the cohort, the primary mode of communication was verbal communication, with 395 of 470 (84%) patients using speech; of those 371 of 395 (94%) spoke English and 24 of 395 (6%) spoke a language other than English. Participants attempting to communicate on the study day had a shorter length of stay (LOS), a mean difference of 3.8 days (95% confidence interval: 0.2; 5.1) shorter LOS in the ICU than those not attempting to communicate, and a mean difference 7.9 days (95% confidence interval: 3.1; 12.6) shorter LOS in hospital overall. Unit-level practices and supports were collected. Six of 44 (14%) ICUs had a protocol for communication management, training was available in 11 of 44 (25%) ICUs, and communication resources were available in 37 of 44 (84%) ICUs. CONCLUSION Three-quarters of patients admitted to the ICU were attempting to communicate on the study day, with multiple methods used to support verbal and nonverbal communication regardless of ventilation status. Guidance and training were absent from the majority of ICUs, indicating a need for development and implementation of policies, training, and resources.

Abstract
BACKGROUND Dysphagia occurs in intensive care unit (ICU) patients. However, there is a lack of epidemiological data on the prevalence of dysphagia in adult ICU patients. OBJECTIVES The objective of this study was to describe the prevalence of dysphagia in nonintubated adult patients in the ICU. METHODS A prospective, multicentre, binational, cross-sectional point prevalence study was conducted in 44 adult ICUs in Australia and New Zealand. Data were collected in June 2019 on documentation of dysphagia, oral intake, and ICU guidelines and training. Descriptive statistics were used to report demographic, admission, and swallowing data. Continuous variables are reported as means and standard deviations (SDs). Precisions of estimates were reported as 95% confidence intervals (CIs). RESULTS Of the 451 eligible participants, 36 (7.9%) were documented as having dysphagia on the study day. In the dysphagia cohort, the mean age was 60.3 years (SD: 16.37) vs 59.6 years (SD: 17.1) and almost two-thirds were female (61.1% vs 40.1%). The most common admission source for those patients with dysphagia were from the emergency department (14/36, 38.9%), and seven of 36 (19.4%) had a primary diagnosis of trauma (odds ratio: 3.10, 95% CI 1.25 - 7.66). There were no statistical differences in Acute Physiology and Chronic Health Evaluation (APACHE II) scores between those with and without a dysphagia diagnosis. Patients with dysphagia were more likely to have a lower mean body weight of 73.3 kg vs 82.1 kg than patients not documented as having dysphagia (95% CI of mean difference: 0.43 to 17.07) and require respiratory support (odds ratio: 2.12, 95% 1.06 to 4.25). The majority of patients with dysphagia were prescribed modified food and fluids in the ICU. Less than half of ICUs surveyed reported unit-level guidelines, resources, or training for management of dysphagia. CONCLUSIONS The prevalence of documented dysphagia in adult ICU nonintubated patients was 7.9%. There were a higher proportion of females with dysphagia than previously reported. Approximately two-thirds of patients with dysphagia were prescribed oral intake, and the majority were receiving texture-modified food and fluids. Dysphagia management protocols, resources, and training are lacking across Australian and New Zealand ICUs.

Abstract
BACKGROUND Critically ill patients commonly receive proton pump inhibitors (PPIs) to prevent gastrointestinal (GI) bleeding from stress-induced ulceration. Despite widespread use in the intensive care unit (ICU), observational data suggest that PPIs may be associated with adverse outcomes in patients with COVID-19 infection. This preplanned study is nested within a large randomized trial evaluating pantoprazole versus placebo in invasively ventilated patients. The 3 objectives are as follows: (1) to describe the characteristics of patients with COVID-19 in terms of demographics, biomarkers, venous thromboembolism, tracheostomy incidence and timing, and other clinical outcomes; (2) to evaluate the impact of COVID-19 infection on clinically important GI bleeding, 90-day mortality, and other outcomes compared to a propensity-matched non-infected cohort; and (3) to explore whether pantoprazole has a differential treatment effect on clinically important GI bleeding, 90-day mortality, and other outcomes in patients with and without COVID-19 infection. METHODS The ongoing trial Re-EValuating the Inhibition of Stress Erosions (REVISE) compares pantoprazole 40 mg IV to placebo on the primary efficacy outcome of clinically important GI bleeding and the primary safety outcome of 90-day mortality. The protocol described in this report is for a substudy focused on patients with COVID-19 infection that was not in the original pre-pandemic trial protocol. We developed a one-page case report form to characterize these patients including data related to biomarkers, venous thromboembolism, COVID-19 therapies, tracheostomy incidence and timing, duration of mechanical ventilation, and ICU and hospital stay. Our analysis will describe the trajectory of patients with COVID-19 infection, a propensity-matched analysis of infected and non-infected patients, and an extended subgroup analysis comparing the effect of PPI among patients with and without COVID-19 infection. DISCUSSION Prophylactic acid suppression in invasively ventilated critically ill patients with COVID-19 infection has unknown consequences. The results of these investigations will inform practice, guidelines, and future research.

Abstract
Objective During the current COVID pandemic, waste generation has been more evident with increased use of single use masks, gowns and other personal protective equipment. We aimed to understand the scale of waste generation, recycling rates and participation in Australian and New Zealand (ANZ) ICUs. Design This is a prospective cross-sectional point prevalence study, as part of the 2021 ANZICS Point Prevalence Program. Specific questions related to waste and sustainability practices were asked at the site and patient level. Setting and participants ANZ adult ICUs and their patients on the day of the study. Main outcome measures Amount of single use items disposed of per shift, as well as the engagement of the site with sustainability and recycling practices. Results In total, 712 patients (median number of patients per ICU = 17, IQR 11-30) from 51 ICUs across ANZ were included in our study; 55% of hospitals had a sustainability officer, and recycling paper (86%) and plastics (65%) were frequent, but metal recycling was limited (27%). Per patient bed space per 12-h shift there was recycling of less than 40% paper, glass, intravenous fluid bags, medication cups and metal instruments. A median of 10 gowns (IQR 3-19.5), 10 syringes (4.5-18) and gloves 30 (18-49) were disposed of per bed space, per 12-h shift. These numbers increased significantly when comparing patients with and without infection control precautions in place. Conclusions In ANZ ICUs, we found utilisation of common ICU consumables to be high and associated with low recycling rates. Interventions to abate resource utilisation and augment recycling are required to improve environmental sustainability in intensive care units.

Abstract
INTRODUCTION In order to better treat obstructive sleep apnea (OSA) in a more efficient and cost-effective way, a joint program between dental clinics and the sleep medicine clinic was piloted at Fort Hood, Texas. Obstructive sleep apnea negatively affects soldier readiness and deployability, leading to the need to establish a successful and proven workflow to treat these patients with oral appliance therapy (OAT). MATERIALS AND METHODS We performed a retrospective review of a de-identified data set which included 288 patients from July 2016 to July 2020. Projected cost data were obtained from routinely collected sleep clinic positive airway pressure (PAP) data. Data were analyzed to determine treatment success and potential cost savings using OAT versus continuous positive airway pressure (CPAP). Patient workflow including successes and challenges with the program is summarized. RESULTS About 85.5% of patients met criteria for successful control of their OSA using OAT as treatment. Five patients did not tolerate OAT and switched back to CPAP. A higher (less severe) O2 nadir on diagnostic polysomnography is moderately correlated with OAT success. Diagnostic Apnea-Hypopnea Index was inversely and weakly correlated with success. Two of the major challenges noted in the program were (1) loss of follow-up and (2) the length of time from oral appliance referral to fitting the oral appliance. If this program was successfully implemented at other Defense Health Agency (DHA) medical treatment facility (MTF) markets nationwide, a potential cost savings of over $500,000/year/MTF could be achieved. CONCLUSIONS Oral appliance therapy has the potential to increase both readiness and deployability for active duty soldiers. Using baseline O2 nadir can help predict success with OAT patients, determining which patients will benefit from this joint program between the dental and medical sleep clinics. Future studies can aim to establish an evidence-based pathway for clinic testing and follow-up. If this patient workflow is implemented properly, there can be significant cost savings army-wide. This all helps The United States Medical Command (MEDCOM) align with the DHA's Quadruple Aim of increased readiness, better health, better care, and lower cost.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus is thought to have originated in wild bats from Asia, and as the resulting pandemic continues into its third year, concerns have been raised that the virus will expand its host range and infect North American wildlife species, including bats. Mexican free-tailed bats (Tadarida brasiliensis) live in large colonies in the southern United States, often in urban areas and, as such, could be exposed to the virus from infected humans. We experimentally challenged wild T. brasiliensis with SARS-CoV-2 to determine the susceptibility, reservoir potential, and population impacts of infection in this species. Of 10 bats oronasally inoculated with SARS-CoV-2, 5 became infected and orally excreted moderate amounts of virus for up to 18 days postinoculation. These five subjects all seroconverted and cleared the virus before the end of the study with no obvious clinical signs of disease. We additionally found no evidence of viral transmission to uninoculated subjects. These results indicate that while T. brasiliensis are susceptible to SARS-CoV-2 infection, infection of wild populations of T. brasiliensis would not likely cause mortality. However, the transmission of SARS-CoV-2 from T. brasiliensis to or from humans, or to other animal species, is a possibility requiring further investigation to better define. IMPORTANCE As the COVID-19 pandemic has continued for 3+ years, there has been increasing concern that the SARS-CoV-2 virus will enter wildlife populations and potentially create new reservoirs where the virus could adapt to a new host and create variants. This is particularly possible with species that reside in man-made structures, in proximity to infected human populations. Mexican free-tailed bats (Tadarida brasiliensis) live in large colonies, often in urban settings and, thus, can be exposed by infected humans and potentially transmit the virus to new hosts. We experimentally challenged T. brasiliensis with SARS-CoV-2 and revealed that they are susceptible to the virus and excrete moderate amounts for up to 18 days postinoculation. This is important information for wildlife biologists, wildlife rehabilitation workers, and the general public that may contact these animals.

Abstract
Aim This audit is performed to see the bacteriology profiles in early-onset sepsis (EOS) and late-onset sepsis (LOS) to compare the microorganisms identified and the antibiotic sensitivity results against hospitals' guidelines for empiric treatment of early and late-onset sepsis. Methods We retrospectively collected the neonate's microbiological data from the laboratory which included the date blood culture (BC) samples were collected, patients' day of life when the samples were collected to determine whether it was EOS or LOS, time to positivity of BC, and antibiotic susceptibility results. Results In EOS, most infection was caused by Gram-positive organisms which were 12 out of 14 isolates (85.7%) with GBS as the most common pathogen identified. In LOS, the number of infections caused by Gram-negative organisms, which were 14 of 25 isolates (56%) was higher than those caused by Gram-positive organisms, which were 11 out of 25 isolates (44%). E. coli was identified as the leading pathogen causing BSI. All organisms were sensitive to the antibiotics used according to the protocol. Conclusion Escherichia coli was the most common organism and was sensitive to the first-line antibiotics used. Group B Streptococcus is still the main pathogen in EOS. The rate of antibiotic resistance is low. The audit showed the importance of analysing the bacteriological and antibiotic susceptibility pattern to ensure optimal treatments are administered to infants.

Abstract
Introduction: Violence in the intensive care unit (ICU) is poorly characterised and its incidence is largely extrapolated from studies in the emergency department. Policy requirements vary between jurisdictions and have not been formally evaluated. Methods: A multisite, single-time point observational study was conducted across Australasian ICUs which focused on the incidence of violence in the previous 24 hours, the characteristics of patients displaying violent behaviour, the perceived contributors, and the management strategies implemented. Unit policies were surveyed across a range of domains relevant to violence management. Results: Data were available for 627 patients admitted to 44 ICUs on one of 2 days in June 2019. Four per cent (25/627) displayed at least one episode of violent behaviour in the previous 24 hours. Violent behaviour was more likely in individuals after a greater length of stay in hospital (incidence, 2%, 4% and 7% for day 0-2, 3-7 and > 7 days respectively; P = 0.01) and in the ICU (2%, 4% and 9% for day 0-2, 3-7 and > 7 of ICU stay respectively; P < 0.01). The most common perceived contributors to violence were confusion (64%), physical illness (40%), and psychiatric illness (34%). Management with chemical sedation (72%) and physical restraint (28%) was commonly required. Clinicians assessed an additional 53 patients (53/627, 9%) as at risk of displaying violence in the next 24 hours. Of the 44 participating ICUs, 30 (68%) had a documented violence procedure. Conclusion: Violence in the ICU was common and frequently required intervention. In this study, one-third of ICUs did not have formal violence procedures, and in those with violence procedures, considerable variation was observed.

Abstract
Objective: To describe pain assessment and analgesic management practices in patients in intensive care units (ICUs) in Australia and New Zealand. Design, setting and participants: Prospective, observational, multicentre, single-day point prevalence study conducted in Australian and New Zealand ICUs. Observational data were recorded for all adult patients admitted to an ICU without a neurological, neurosurgical or postoperative cardiac diagnosis. Demographic characteristics and data on pain assessment and analgesic management for a 24-hour period were collected. Main outcome measures: Types of pain assessment tools used and frequency of their use, use of opioid analgesia, use of adjuvant analgesia, and differences in pain assessment and analgesic management between postoperative and non-operative patients. Results: From the 499 patients enrolled from 45 ICUs, pain assessment was performed at least every 4 hours in 56% of patients (277/499), most commonly with a numerical rating scale. Overall, 286 patients (57%) received an opioid on the study day. Of the 181 mechanically ventilated patients, 135 (75%) received an intravenous opioid, with the predominant opioid infusion being fentanyl. The median dose of opioid infusion for ventilated patients was 140 mg oral morphine equivalents. Of the 318 non-ventilated patients, 41 (13%) received patient-controlled analgesia and 76 (24%) received an oral opioid, with the predominant opioid being oxycodone. Paracetamol was administered to 63 ventilated patients (35%) and 164 non-ventilated patients (52%), while 2% of all patients (11/499) received a non-steroidal anti-inflammatory drug. Ketamine infusion and regional analgesia were used in 15 patients (3%) and 17 patients (3%), respectively. Antineuropathic agents (predominantly gabapentinoids) were used in 53 patients (11%). Conclusions: Although a majority of ICU patients were frequently assessed for pain with a validated pain assessment tool, cumulative daily doses of opioids were high, and the use of multimodal adjuvant analgesia was low. Our data on current pain assessment and analgesic management practices may inform further research in this area.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus originated in wild bats from Asia, and as the resulting pandemic continues into its third year, concerns have been raised that the virus will expand its host range and infect North American wildlife species, including bats. Mexican free-tailed bats ( Tadarida brasiliensis : TABR) live in large colonies in the southern United States, often in urban areas, and as such, could be exposed to the virus from infected humans. We experimentally challenged wild TABR with SARS-CoV-2 to determine the susceptibility, reservoir potential, and population impacts of infection in this species. Of nine bats oronasally inoculated with SARS-CoV-2, five became infected and orally excreted moderate amounts of virus for up to 18 days post inoculation. These five subjects all seroconverted and cleared the virus before the end of the study with no obvious clinical signs of disease. We additionally found no evidence of viral transmission to uninoculated subjects. These results indicate that while TABR are susceptible to SARS-CoV-2 infection, infection of wild populations of TABR would not likely cause mortality. However, the transmission of SARS-CoV-2 from TABR to or from humans, or to other animal species, is a distinct possibility requiring further investigation to better define.

Abstract
Background Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference –1·69 [–9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5–8] vs 6 [5–8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52–23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75–0·86]; p<0·0001). Interpretation Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status. Funding No funding.

Abstract
Aim Peritonsillar abscess (PTA) is the most common suppurative complication of acute tonsillitis. It requires urgent specialist treatment due to the risk of progression to airway compromise. We aimed to review referral pathways to a dedicated otolaryngology emergency department (ORL-ED), identify causative organisms and discuss COVID-19 implications. Methods A retrospective review of patients presenting to the ORL-ED between January 2018 and December 2019 was undertaken. Data extracted included demographics, referral source, treatment, microbiology results and length of stay. Statistical analysis of seasonal variation of presentation and causative organisms employed Chi-Square and Fisher's Exact Test, respectively. Results There were 53 PTA presentations. 51 were admitted accounting for 44.3% (51/115) of ED admissions. The median patient age was 31 years (IQR 20-40yrs). GP referral accounted for 48/53 (90.6%). There was no statistically significant seasonality (χ2=5.94, p=0.11) in presentation. Microbiology samples were available for 44 patients. Streptococcus was identified in 19/44 (43.2%) patients. 85% (45/53) of patients received Co-amoxiclav. Discussion PTA is a perennial condition with diverse causative organisms. Antibiotic choice should reflect this. The majority of patients are referred from primary care, emphasising the role of the GP in initial diagnosis and the importance of clinical education in this regard.

Abstract
BACKGROUND Device-related pressure injuries (DRPIs) are an ongoing iatrogenic problem evident in intensive care unit (ICU) settings. Critically ill patients are at high risk of developing pressure injuries caused by devices. OBJECTIVE The aim of the study was to determine the prevalence of DRPI in critically ill patients in intensive care and the location, stage, and attributable device of DRPI and describe the products and processes of care used to prevent these injuries. METHODS This was a prospective, multicentre, cross-sectional point prevalence study of patients aged more than 16 years in Australian and New Zealand ICUs. The study was part of the Australian and New Zealand Intensive Care Society Clinical Trials Group Point Prevalence Program coordinated by The George Institute for Global Health. MAIN OUTCOME MEASURE Identification of DRPI on the study day was the main outcome measure. RESULTS Of the 624 patients included from 44 participating ICUs, 27 were found to have 35 identified DRPIs, giving a point prevalence DRPI rate of 4.3% (27/624). Study patients had a mean age of 59 years, and 60.3% were men. Patients with DRPI compared with patients without DRPI were significantly heavier (median: 92 kg versus 80 kg, respectively, p = 0.027), were less likely to survive the ICU (63.0% versus 85.9%, respectively, p = 0.015), had higher Acute Physiology and Chronic Health Evaluation II scores at admission to the ICU (median: 20 versus 16, respectively, p = 0.001), received mechanical ventilation more often (88.9% versus 43.5%, respectively, p < 0.001), and were more frequently diagnosed with respiratory conditions (37.0% versus 18.6%, respectively, p = 0.022). Processes of care activities were surveyed in 42 ICUs. Most DRPIs were attributed to endotracheal tubes and other respiratory devices. Forty-two ICUs reported processes of care to prevent DRPI, and just more than half of the participating sites (54.8%, 23/44) reported a dedicated ICU-based protocol for prevention of DRPI. CONCLUSION DRPIs pose a burden on patients in the ICU. Our study showed a DRPI prevalence comparable with other studies. Prevention strategies targeting DRPI should be included in ICU-specific pressure injury prevention guidelines or protocols.

Abstract
Insect damage to, and sub-optimal harvesting practices of the Papaver somniferum poppy are associated with contamination of its seeds with opium alkaloids. Consumption of poppy seeds has been linked to opium-like overdose symptoms, such as reduced consciousness and respiratory depression. However, acute cardiotoxicity secondary to ingestion of contaminated poppy seeds has not been reported previously. We report a case of a 21-year-old man who presented with severe biventricular dysfunction and cardiogenic shock following consumption of homemade poppy seed tea. We highlight the importance of prompt recognition of the myocardial effects of opiates along with the more common respiratory and neurological effects. In this case, the acute cardiotoxicity was fully reversed with high-dose naloxone, milrinone and noradrenaline. In addition, we recommend offering high-level care due to the possibility that specialist cardiac services may be required. Ergo, early transfer to an appropriate centre is recommended.

Abstract
Objective: To characterise the assessment and management of delirium in patients admitted to intensive care units (ICUs) in Australia and New Zealand. Methods: We conducted a multicentre observational point prevalence study across 44 adult Australian and New Zealand ICUs. Data were extracted for all patients in the ICU in terms of assessment and treatment of delirium. ICU-level data were collected regarding the use of explicit protocols related to delirium. Results: We studied 627 patients, with 54% (336/627) having at least one delirium screening assessment performed. The Confusion Assessment Method for the ICU (CAM-ICU) was the most frequently used tool (88%, 296/336). Of patients assessed, 20% (68) were identified to have delirium. Eighteen per cent (111) of patients were administered a drug to manage delirium, with 41% (46) of those receiving a drug having no recorded assessment for delirium on that day. Of the drugs used to treat delirium, quetiapine was the most frequently administered. Physical restraints were applied to 8% (48/626) of patients, but only 17% (8/48) of such patients had been diagnosed with delirium. Most physically restrained patients either did not have delirium diagnosed (31%, 15/48) or had no formal assessment recorded (52%, 25/48) on that day. Conclusions: On the study day, more than 50% of patients had a delirium screening assessment performed, with 20% of screened patients deemed to have delirium. Drugs that are prescribed to treat delirium and physical restraints were frequently used in the absence of delirium or the formal assessment for its presence.

Abstract
Background Oncoplastic surgery (ops) is becoming the new standard of care for breast-conserving surgery, leading to some challenges with adjuvant radiation, particularly when accurate tumour bed (tbd) delineation is needed for focused radiation (that is, accelerated partial breast irradiation or boost radiation). Currently, no guidelines have been published concerning tbd localization for adjuvant targeted radiation after ops. Methods A modified Delphi method was used to establish consensus by a panel of 20 experts in surgical and radiation oncology at the Canadian Locally Advanced Breast Cancer National Consensus Group and in a subsequent online member survey. Results These are the main recommendations:■ Surgical clips are necessary and should, at a minimum, be placed along the 4 side walls of the cavity, plus 1-4 clips at the posterior margin if necessary.■ Operative reports should include pertinent information to help guide the radiation oncologists.■ Breast surgeons and radiation oncologists should have a basic understanding of ops techniques and work on "speaking a common language."■ Careful consideration is needed when determining the value of targeted radiation, such as boost, in higher-level ops procedures with extensive tissue rearrangement. Conclusions The panel developed a total of 6 recommendations on tbd delineation for more focused radiation therapy after ops, with more than 80% agreement on each statement. All are summarized, together with the corresponding evidence or expert opinion.

Abstract
Aims To determine the impact of applying the Neonatal Early Onset Sepsis Calculator (NEOSC) to clinical practice. We evaluated this multivariable risk prediction model, used in the assessment of infants >35 weeks GA, at risk of neonatal sepsis. Methods A retrospective, cohort study comparing the rates of blood culture use in a large maternity hospital before and after the introduction of the NEOSC. Cases were ascertained from the records of the Department of Microbiology. The key variables were the number of blood cultures (all gestational ages, <72 hours old), infant antibiotic use and sepsis rates. Data for three years prior to NEOSC use (January 2015 - December 2017) were compared with 15 months (January 2018 - Q1 2019) after it was implemented. Results Pre- and post- NEOSC use, the total blood cultures taken annually were: 1,312 (2015), 1,149 (2016), 1,319 (2017) and 702 (2018), 192 (Q1 2019) respectively, a statistically significant reduction [p < 0.00001, 95% CI]. There was no significant difference in rates of either: culture-confirmed GBS-sepsis [p value 0.18, 95% CI] or other-pathogen sepsis [p value 0.32, 95%CI] in term infants between the two periods. There was a significant reduction in antibiotic use in the first 24 hours of life (average 11.3% pre-NEOSC and 5.9% after NEOSC was implemented) [p < 0.00001, 95% CI]. Conclusion The introduction of the NEOSC has reduced blood culture and antibiotic use. This has been achieved without any increase in infection rates.

Abstract
BACKGROUND AND RATIONALE β-Lactam antibiotics display a time-dependent mechanism of action, with evidence suggesting improved outcomes when administering these drugs via continuous infusion compared with standard intermittent infusion. However, there is no phase 3 randomised controlled trial (RCT) evidence to support one method of administration over another in critically ill patients with sepsis. DESIGN AND SETTING The β-Lactam Infusion Group (BLING) III study is a prospective, multicentre, open, phase 3 RCT to compare continuous infusion with standard intermittent infusion of β-lactam antibiotics in critically ill patients with sepsis. The study will be conducted in about 70 intensive care units (ICUs) in Australia, New Zealand, the United Kingdom, Belgium and selected other countries, from 2018 to 2021. PARTICIPANTS AND INTERVENTIONS BLING III will recruit 7000 critically ill patients with sepsis being treated with one of two β-lactam antibiotics (piperacillin-tazobactam or meropenem) to receive the β-lactam antibiotic by either continuous or intermittent infusion. MAIN OUTCOME MEASURES The primary outcome is allcause mortality within 90 days after randomisation. Secondary outcomes are clinical cure at Day 14 after randomisation, new acquisition, colonisation or infection with a multiresistant organism or Clostridium difficile diarrhoea up to 14 days after randomisation, all-cause ICU mortality and all-cause hospital mortality. Tertiary outcomes are ICU length of stay, hospital length of stay and duration of mechanical ventilation and duration of renal replacement therapy up to 90 days after randomisation. RESULTS AND CONCLUSIONS The BLING III study will compare the effect on 90-day mortality of β-lactam antibiotics administered via continuous versus intermittent infusion in 7000 critically ill patients with sepsis. TRIAL REGISTRATION ClinicalTrials.gov Registry (NCT03213990).

Abstract
PurposeFungal keratitis is relatively rare in temperate climates with only one previous population-based study, which reported a minimum annual incidence of 0.32 per million population in the United Kingdom. We performed a nationwide study in the Republic of Ireland of cases over a 6-year period to establish the incidence, risk factors, treatment, and outcomes of fungal keratitis.Patients and methodsAll corneal scraping specimens positive for fungal species over a 6-year period were identified at the microbiology departments of the seven main ophthalmology units in the Republic of Ireland. Census data was used to establish national minimum annual incidence.ResultsForty-two eyes were treated for confirmed fungal keratitis during the 6-year period. This resulted in a minimum incidence of 1.53 cases per million population per year. Twenty-eight of 42 cases (67%) were due to filamentary fungi, with the most common species being Aspergillus. Pre-existing ocular surface disease was the most common risk factor constituting 42.9%; 26.2% underwent keratoplasty. No eyes underwent evisceration. Two eyes resulted in a level of vision of no perception of light. The mean LogMAR acuity in the remainder of cases was 0.89 with a range from -0.10 to 4.00.ConclusionThis study demonstrates a much higher minimum annual incidence than previously reported. The causative organism is highly related to risk factor. The range of visual outcomes remains broad in all subgroups. The wide range of outcomes and treatments used highlights the need for better evidence-based guidelines for fungal keratitis.

Abstract
Pigeon paramyxovirus serotype 1 (PPMV-1) is a globally distributed, virulent member of the avian paramyxovirus serotype 1 serogroup that causes mortality in columbiformes and poultry. Following introduction into the United States in the mid-1980s, PPMV-1 rapidly spread causing numerous mortality events in Eurasian collared-doves ( Streptopelia decaocto) (ECDOs) and rock pigeons ( Columba livia) (ROPIs). The investigators reviewed pathological findings of 70 naturally infected, free-ranging columbiforms from 25 different mortality events in the United States. Immunohistochemistry targeting PPMV-1 nucleoprotein was used to determine the tissue distribution of the virus in a subset of 17 birds from 10 of the studied outbreaks. ECDOs (61 birds) and ROPIs (9 birds) were the only species in which PPMV-1-associated disease was confirmed by viral isolation and presence of histologic lesions. Acute to subacute tubulointerstitial nephritis and necrotizing pancreatitis were the most frequent histologic lesions, with immunolabeling of viral antigen in renal tubular epithelial cells and pancreatic acinar epithelium. Lymphoid depletion of bursa of Fabricius and spleen was common, but the presence of viral antigen in these organs was inconsistent among infected birds. Hepatocellular necrosis was occasionally present with immunolabeling of hypertrophic Kupffer cells, and immunopositive eosinophilic intracytoplasmic inclusion bodies were present in hepatocytes of 1 ECDO. Immunopositive lymphocytic choroiditis was present in 1 ECDO, while lymphocytic meningoencephalitis was frequent in ROPIs in absence of immunolabeling. This study demonstrates widespread presence of PPMV-1 antigen in association with histologic lesions, confirming the lethal potential of this virus in these particular bird species.

Abstract
ACCESSIBLE SUMMARY People with severe mental ill health are up to three times more likely to smoke than other members of the general population. Life expectancy in this client group is reduced by up to 30 years, and smoking is the single most important cause of premature death. The aim of this study was to explore why people with severe mental ill health smoked and why they might want to stop smoking or cut down on the amount of cigarettes that they smoked. The study found that people with severe mental ill health are motivated to cut down or stop smoking, and this is mainly due to concerns about their own health. The reasons people gave for smoking were to relieve stress, to help relax and for something to do when they are bored. Health professionals should offer evidence supported smoking cessation therapy to people with severe mental ill health. In addition to standard National Health Service smoking cessation treatments such as pharmacotherapy and behavioural support. Practitioners should help people with serious mental ill health to identify meaningful activities to relieve boredom and challenge any incorrect beliefs they hold that smoking helps relaxation and relieves stress. ABSTRACT Smoking is the single most preventable cause of premature mortality for people with serious mental ill health (SMI). Yet little is known about the reasons why service users smoke or what their motivations for quitting might be. The aim of this paper is to explore smoking behaviours, reasons for smoking and motivations for cutting down/stopping smoking in individuals with SMI who expressed an interest in cutting down or stopping smoking. Prior to randomization, the smoking behaviours and motivations for wanting to cut down or stop smoking of participants in a randomized trial were systematically assessed. Participant's primary reasons for continuing to smoke were that they believed it helped them to cope with stress, to relax and relieve boredom. Participant's main motivations for wanting to cut down or stop smoking were related to concerns for their own health. Previous attempts to stop smoking had often been made alone without access to evidence supported smoking cessation therapy. Future recommendations include helping people with SMI to increase their activity levels to relieve boredom and inspire confidence in their ability to stop smoking and challenging beliefs that smoking aids relaxation and relieves stress.

Abstract
Infants born to women with hepatitis B virus (HBV) are at risk of vertical transmission. This risk is significantly reduced with correct post-natal treatment After initial perinatal management and neonatal treatment, these infants receive subsequent follow up HBV immunisations at two, four and six months. These infants then require post vaccination serological testing. This review was conducted to determine the number of infants born to mothers with HBV in the National Maternity Hospital who had appropriate post vaccination serological testing. There were seventy-eight HBV infections identified antenatally in the years 2010 and 2011 resulting in seventy live born infants at our institution. Thirteen (18.6%) infants had evidence of post vaccination serological testing. This is below international rates of follow up. There is an urgent need for a centralised national programme to ensure adequate follow up and management of all infants born to women with HBV in Ireland.

Abstract
Background: Little is known about quality of life and work productivity in autoimmune bullous dermatoses (AIBDs). Objective: To determine the impact of AIBDs on quality of life and work productivity. Methods: An observational cross-sectional study took place between February and May 2013 at an AIBD tertiary referral centre. Ninety-four patients were included. All participants completed the Dermatology Life Quality Index and the Work Productivity and Activity Impairment–Specific Health Problem questionnaires. Results: Responders to treatment had less impairment ( P < .001) than nonresponders. Patients with severe AIBD had significantly more impairment that those with mild ( P < .001) and moderate ( P = .002) AIBD. Greater impairment was associated with higher percentage of work missed. Those with a higher Dermatology Life Quality Index score had greater work impairment and overall activity impairment ( P = .041, P = .024). Nonresponders had increased impairment while working ( P < .001), overall work impairment ( P < .001), and activity impairment ( P < .001). Severely affected patients had worse impairment in all Work Productivity and Activity Impairment Questionnaire domains. Conclusions: AIBD has the potential to be a large burden on ability to work and quality of life. Larger studies are needed to clarify how these domains change over time and whether or not they improve with treatment.

Abstract
BACKGROUND Bowel management protocols have the potential to minimize complications for critically ill patients. Targeted implementation can increase the uptake of protocols by clinicians into practice. The theory of planned behaviour offers a framework in which to investigate clinicians' intention to perform the behaviour of interest. This study aimed to evaluate the effect of implementing a bowel management protocol on intensive care nursing and medical staffs' knowledge, attitude, subjective norms, perceived behavioural control, behaviour intentions, role perceptions and past behaviours in relation to three bowel management practices. METHODS A descriptive before and after survey using a self-administered questionnaire sent to nursing and medical staff working within three intensive care units before and after implementation of our bowel management protocol (pre: May - June 2008; post: Feb - May 2009). RESULTS Participants had significantly higher knowledge scores post-implementation of our protocol (pre mean score 17.6; post mean score 19.3; p = 0.004). Post-implementation there was a significant increase in: self-reported past behaviour (pre mean score 5.38; post mean score 7.11; p = 0.002) and subjective norms scores (pre mean score 3.62; post mean score 4.18; p = 0.016) for bowel assessment; and behaviour intention (pre mean score 5.22; post mean score 5.65; p = 0.048) for administration of enema. CONCLUSION This evaluation, informed by the theory of planned behaviour, has provided useful insights into factors that influence clinician intentions to perform evidence-based bowel management practices in intensive care. Addressing factors such as knowledge, attitudes and beliefs can assist in targeting implementation strategies to positively affect clinician behaviour change. Despite an increase in clinicians' knowledge scores, our implementation strategy did not, however, significantly change clinician behaviour intentions for all three bowel management practices. Further research is required to explore the influence of opinion leaders and organizational culture on clinicians' behaviour intentions related to bowel management for intensive care patients.

Abstract
Universal antenatal screening for T. pallidum is standard in Irish maternity units. The prevalence of adult syphilis has increased in Ireland. We audited the neonatal management of infants exposed to T. pallidum in utero. A cross sectional retrospective analysis of all pregnancies with confirmed positive serology for T. pallidum from January 2005 to December 2010 was conducted at the National Maternity Hospital, Holles St. Data were analysed using SPSS 14.0. Ethical approval was obtained. There were 55,058 live births during the study period. Fifty-eight women had positive serology and 41 met inclusion criteria. Infant evaluation and follow up was decided by allocation to an evidence based algorithm. Twenty-one infants (51%) were accurately allocated and assessed, 5 (12%) had a partial assessment and the algorithm was incorrectly applied in 15 (36%) of cases. Failure to adhere to evidence based neonatal guidelines is common and undermines efficacy of the screening program.

Abstract
AIMS AND OBJECTIVES To evaluate the effect of a multifaceted implementation of a bowel management protocol on outcomes for intensive care patients, in particular the incidence of constipation and diarrhoea, and on clinicians' bowel management practices. BACKGROUND Complications associated with poor bowel management for critically ill patients result in adverse outcomes. Implementation of protocols requires strategies proven to change clinician behaviour. DESIGN Before and after study. METHODS Our bowel management protocol was implemented using three evidence-based elements: education sessions, printed educational materials in the form of a fact sheet and reminders. We retrospectively collected data from patients' medical records admitted at two time points within three Sydney metropolitan intensive care units (preimplementation, n = 101; postimplementation, n = 107). RESULTS No significant difference was found in the incidence of constipation and diarrhoea pre and postimplementation of the protocol. Seventy-two per cent (n = 73) of patients preimplementation and 70% (n = 75) of patients postimplementation experienced one or more episodes of constipation (bowels not open for 72 hours or greater), and 16% (n = 16) of patients preimplementation and 20% (n = 21) of patients postimplementation experienced one or more episodes of diarrhoea. There was a slight nonsignificant increase in bowel assessment on admission by medical officers postimplementation (pre, 47%, n = 48; post, 60%, n = 64). CONCLUSION Targeted multifaceted implementation of a bowel management protocol did not have an impact on the incidence of constipation or diarrhoea for intensive care patients or on clinician practices. The lack of impact on patient outcomes may be due to clinicians' nonadherence to our bowel management protocol. Reasons clinicians' practices did not change may include the influences of clinical decision-making on behaviour. RELEVANCE TO CLINICAL PRACTICE This study highlights difficulties inherent in changing clinician behaviour and practices to improve patient outcomes despite using an evidence-based multifaceted implementation strategy. Further research is required to ascertain the most effective implementation strategies.
