Abstract
BACKGROUND Invasive fungal disease (IFD) in the early post-allogeneic HSCT (alloHCT) period is associated with increased likelihood of catastrophic outcomes. The utility of oral modified release (MR) posaconazole tablets is limited by reduced drug absorption from gastrointestinal toxicity induced by cytotoxic chemotherapy, necessitating a switch to the IV posaconazole formulation. OBJECTIVES To describe the population pharmacokinetics of posaconazole for oral MR and IV formulations in alloHCT patients and determine dosing regimens likely to achieve therapeutic exposures. METHODS We performed a prospective observational pharmacokinetic study in adult patients in the early post-alloHCT period requiring a change in posaconazole formulation (oral to IV). Samples were analysed using a validated LC-MS/MS method. Population pharmacokinetic analysis and Monte Carlo simulations (n = 1000) were performed using Pmetrics for R. RESULTS Twenty patients aged between 21 and 70 years were included in the study. A two-compartment model, incorporating mucositis/diarrhoea to modify the bioavailability for oral administration best described the data. To achieve ≥90% PTA, simulations showed that higher than currently recommended doses of oral MR posaconazole were required for prophylaxis Cmin targets (≥0.5 and ≥0.7 mg/L), while increased doses of both formulations were required for IFD treatment PK/PD targets, with patients experiencing oral mucositis/diarrhoea unlikely to achieve these. CONCLUSIONS Increased doses of posaconazole should be considered for both prophylaxis and treatment of IFD to increase the proportion of alloHCT patients achieving therapeutic exposures, particularly the oral formulation in patients with mucositis and/or diarrhoea. Posaconazole therapeutic drug monitoring should be considered for all formulations in this setting.

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
Background It is unknown whether increasing dietary protein to 1.2-2.0 g/kg/day as recommended in international guidelines compared to current practice improves outcomes in intensive care unit (ICU) patients. The TARGET Protein trial will evaluate this. Objective To describe the study protocol for the TARGET Protein trial. Design setting and participants TARGET Protein is a cluster randomised, cross-sectional, double cross-over, pragmatic clinical trial undertaken in eight ICUs in Australia and New Zealand. Each ICU will be randomised to use one of two trial enteral formulae for three months before crossing over to the other formula, which is then repeated, with enrolment continuing at each ICU for 12 months. All patients aged ≥16 years in their index ICU admission commencing enteral nutrition will be eligible for inclusion. Eligible patients will receive the trial enteral formula to which their ICU is allocated. The two trial enteral formulae are isocaloric with a difference in protein dose: intervention 100g/1000 ml and comparator 63g/1000 ml. Staggered recruitment commenced in May 2022. Main outcomes measures The primary outcome is days free of the index hospital and alive at day 90. Secondary outcomes include days free of the index hospital at day 90 in survivors, alive at day 90, duration of invasive ventilation, ICU and hospital length of stay, incidence of tracheostomy insertion, renal replacement therapy, and discharge destination. Conclusion TARGET Protein aims to determine whether augmented enteral protein delivery reduces days free of the index hospital and alive at day 90.

Abstract
Treatment of cytomegalovirus (CMV) infection in allogeneic hematopoietic stem cell transplantation (alloHCT) patients with ganciclovir is complicated by toxicity and resistance. This study aimed to develop an intravenous ganciclovir population pharmacokinetic model for post-alloHCT patients and to determine dosing regimens likely to achieve suggested therapeutic exposure targets. We performed a prospective observational single-center pharmacokinetic study in adult alloHCT patients requiring treatment with intravenous ganciclovir for CMV viremia or disease. Samples were analyzed using a validated ultraperformance liquid chromatography method. Population pharmacokinetic analysis and Monte Carlo simulations (n = 1000) were performed using Pmetrics for R. Twenty patients aged 18 to 69 years were included in the study. A 2-compartment model with linear elimination from the central compartment and between occasion variability best described the data. Incorporating creatinine clearance (CLCR) estimated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and presence of continuous renal replacement therapy as covariates for ganciclovir clearance improved the model. Compared to current dosing recommendations, simulations demonstrated loading doses were required to achieve a target AUC24 of 80 to 120 mg.h/L on day 1 of induction therapy. Increased individualization of post-loading induction and maintenance doses based on CLCR is required to achieve the suggested exposures for efficacy (AUC24 >80/>40 mg.h/L for induction/maintenance) while remaining below the exposure thresholds for toxicity (AUC24 <120/<60 mg.h/L for induction/maintenance). Intravenous ganciclovir dosing in alloHCT patients can be guided by CLCR estimated by CKD-EPI. Incorporation of loading doses into induction dosing regimens should be considered for timely achievement of currently suggested exposures.

Abstract
BACKGROUND Limited consensus exists on the optimal use of antifungal agents to prevent invasive fungal infection in the early post allogeneic hematopoietic stem cell transplant (alloHCT) period, particularly when patients cannot tolerate oral medication administration. METHODS We undertook a retrospective observational cohort study to assess the tolerability, efficacy, and cost of a new antifungal prophylaxis pathway at a major tertiary alloHCT centre. Patients aged ≥16 years who underwent alloHCT between February 2018 and October 2019 (cohort 1) or between April 2020 and November 2021 (cohort 2) were included. In both cohorts, first line prophylactic therapy was oral posaconazole. The second line drugs where oral therapy was unable to be administered were intravenous voriconazole (cohort 1) versus intravenous posaconazole (cohort 2). RESULTS There were 142 patients enrolled in the study, 71 in each cohort. The proportion of patients remaining on first-line prophylaxis or progressing to second-, third-, and fourth-line options was 22.5%, 39.4%, 29.6%, and 8.5% in cohort 1 and 39.4%, 59.2%, 1.4%, and 0% in cohort 2, respectively. The frequency of neuropsychiatric adverse events was significantly higher in cohort 1 compared to cohort 2 (49.3% vs. 19.8%, p = .0004). Occurrence of proven and probable fungal infections was not significantly different between cohorts. Antifungal drug expenditure was $359 935 (AUD) more in cohort 1 ($830 486 AUD) compared to cohort 2 ($477 149 AUD). CONCLUSION The antifungal prophylaxis pathway used in cohort 2 resulted in reduced antifungal-associated adverse effects, less patients requiring progression to 3rd and 4th line prophylaxis and reduced antifungal drug costs.

Abstract
Intravenous fluid resuscitation is recommended first-line treatment for sepsis-associated hypotension and/or hypoperfusion. The rationale is to restore circulating volume and optimize cardiac output in the setting of shock. Nonetheless, there is limited high-level evidence to support this practice. Over the past decade emerging evidence of harm associated with large volume fluid resuscitation among patients with septic shock has led to calls for a more conservative approach. Specifically, clinical trials undertaken in Africa have found harm associated with initial fluid resuscitation in the setting of infection and hypoperfusion. While translating these findings to practice in other settings is problematic, there has been a re-appraisal of current practice with some recommending earlier use of vasopressors rather than repeated fluid boluses as an alternative to restore perfusion in septic shock. There is consequently uncertainty and variation in practice. The question of fluids or vasopressors for initial resuscitation in septic shock is the subject of international multicentre clinical trials.

Abstract
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
BACKGROUND Slow gastric emptying occurs frequently during critical illness and is roughly quantified at bedside by large gastric residual volumes (GRVs). A previously published trial (The Augmented versus Routine approach to Giving Energy Trial; TARGET) reported larger GRVs with energy-dense (1.5 kcal/mL) compared with standard (1.0 kcal/mL) enteral nutrition (EN), warranting further exploration. OBJECTIVE To assess the incidence, risk factors, duration, and timing of large GRVs (≥250 mL) and its relation to clinical outcomes in mechanically ventilated adults. METHODS A post-hoc analysis of TARGET data in patients with ≥1 GRV recorded. Data are n (%) or median [IQR]. RESULTS Of 3876 included patients, 1777 (46%) had ≥1 GRV ≥250 mL, which was more common in males (50 compared with 39%; P < 0.001) and in patients receiving energy-dense compared with standard EN (52 compared with 40%; RR = 1.27 (95% CI: 1.19, 1.36); P < 0.001) in whom it also lasted longer (1 [0-2] compared with 0 [0-1] d; P < 0.001), with no difference in time of onset after EN initiation (day 1 [0-2] compared with 1 [0-2]; P = 0.970). Patients with GRV ≥250 mL were more likely to have the following: vasopressor administration (88 compared with 76%; RR = 1.15 [1.12, 1.19]; P < 0.001), positive blood cultures (16 compared with 8%; RR = 1.92 [1.60, 2.31]; P < 0.001), intravenous antimicrobials (88 compared with 81%; RR = 1.09 [1.06, 1.12]; P < 0.001), and prolonged intensive care unit (ICU) stay (ICU-free days to day 28; 12.9 [0.0-21.0] compared with 20.0 [3.9-24.0]; P < 0.001), hospital stay (hospital-free days to day 28: 0.0 [0.0-12.0] compared with 7.0 [0.0-17.6] d; P < 0.001), ventilatory support (ventilator-free days to day 28: 16.0 [0.0-23.0] compared with 22.0 [8.0-25.0]; P < 0.001), and a higher 90-d mortality (29 compared with 23%; adjusted: RR = 1.17 [1.05, 1.30]; P = 0.003). CONCLUSION Large GRVs were more common in males and those receiving energy-dense formulae, occurred early and were short-lived, and were associated with a number of negative clinical sequelae, including increased mortality, even when adjusted for illness severity. This trial was registered at clinicaltrials.gov as NCT02306746.

Abstract
Objective: To quantify current protein prescription and delivery in critically ill adults in Australia and New Zealand and compare it with international guidelines. Design: Prospective, multicentre, observational study. Setting: Five intensive care units (ICUs) across Australia and New Zealand. Participants: Mechanically ventilated adults who were anticipated to receive enteral nutrition for ≥ 24 hours. Main outcome measures: Baseline demographic and nutrition data in ICU, including assessment of requirements, prescription and delivery of enteral nutrition, parenteral nutrition and protein supplementation, were collected. The primary outcome was enteral nutrition protein delivery (g/kg ideal body weight [IBW] per day). Data are reported as mean ± standard deviation or n (%). Results: 120 patients were studied (sex, 60% male; mean age, 59 ± 16 years; mean admission APACHE II score, 20 ± 8). Enteral nutrition was delivered on 88%, parenteral nutrition on 6.8%, and protein supplements on 0.3% of 1156 study days. For the 73% (88/120) of patients who had a nutritional assessment, the mean estimated protein requirements were 99 ± 22 g/day (1.46 ± 0.55 g/kg IBW per day). The mean daily protein delivery was 54 ± 23 g (0.85 ± 0.35 g/kg IBW per day) from enteral nutrition and 56 ± 23 g (0.88 ± 0.35 g/kg IBW per day) from all sources (enteral nutrition, parenteral nutrition, protein supplements). Protein delivery was ≥ 1.2 g/kg IBW per day on 29% of the total study days per patient. Conclusions: Protein delivery as a part of current usual care to critically ill adults in Australia and New Zealand remains below that recommended in international guidelines.

Abstract
Objective: To determine the cost-effectiveness of early goal-directed therapy (EGDT) for patients with early septic shock. Design: Within-trial cost-effectiveness evaluation. Setting: Nineteen hospitals in Australia and New Zealand. Participants and interventions: Patients with early septic shock enrolled in the Australasian Resuscitation in Sepsis Evaluation (ARISE) trial were randomly assigned to EGDT versus usual care. A subgroup of patients participated in a nested economic evaluation study in which detailed resource use data were collected until 12 months after randomisation. Outcome measures: Clinical outcomes included lives saved, life-years gained and quality-adjusted life-years (QALYs), with mortality collected until 12 months and health-related quality of life assessed at baseline, 6 and 12 months using the 3-level EuroQol five dimensions questionnaire (EQ-5D-3L). Economic outcomes included health care resource use, costs and cost-effectiveness from the Australian health care payer perspective. Results: A total of 205 patients (100 EGDT, 105 usual care) participated in the nested economic evaluation study, of which 203 had complete resource use data. Unadjusted mean health care costs to 12 months were $67 223 (standard deviation [SD], $72 397) in the EGDT group and $54 179 (SD, $61 980) in the usual care group, with a mean difference of $13 044 (95% CI, -$5791 to $31 878). There was no difference between groups with regards to lives saved (EGDT, 69.4% v usual care, 68.6%; P = 1.0), life-years gained (mean EGDT, 0.746 [SD, 0.406] v usual care, 0.725 [SD, 0.417]; P = 0.72) or QALYs (mean EGDT, 0.318 [SD, 0.291] v usual care, 0.367 [SD, 0.295]; P = 0.24). EGDT was dominated (higher costs, lower effectiveness) by usual care in 80.4% of bootstrap replications. For a willingness-to-pay threshold of $50 000 per QALY, the probability of EGDT being cost-effective was only 6.4%. Conclusions: In patients presenting to the emergency department with early septic shock, EGDT compared with usual care was not cost-effective. Clinical trial registration:ClinicalTrials.gov number NCT00975793.

Abstract
OBJECTIVE Intravenous antimicrobial therapy within 1 h of the diagnosis of septic shock is recommended in international sepsis guidelines. We aimed to evaluate the association between antimicrobial timing and mortality in patients presenting to the ED with septic shock. METHODS Post-hoc analysis of 1587 adult participants enrolled in the Australasian Resuscitation in Sepsis Evaluation (ARISE) multicentre trial of early goal-directed therapy for whom the time of initial antimicrobial therapy was recorded. We compared participants who had initiation of antimicrobials within the first hour (early) or later (delayed) of ED presentation. A propensity score model using inverse probability of treatment weighting was constructed to account for confounding baseline covariates. The primary outcome was 90-day mortality. RESULTS The median (interquartile range) time to initiating antimicrobials was 69 (39-112) min with 712 (44.9%) participants receiving the first dose within the first hour of ED presentation. Compared with delayed therapy, early administration was associated with increased baseline illness severity score and greater intensity of resuscitation pre-randomisation (fluid volumes, vasopressors, invasive ventilation). All-cause 90-day mortality was also higher; 22.6% versus 15.5%; unadjusted odds ratio (OR) 1.58 (95% confidence interval [CI] 1.16-2.15), P = 0.004. After inverse probability of treatment weighting, the mortality difference was non-significant; OR 1.30 (95% CI 0.95-1.76), P = 0.1. Live discharge rates from ICU (OR 0.81, 95% CI 0.72-0.91; P = 0.80) and hospital (OR 0.93, 95% CI 0.82-1.06; P = 0.29) were also not different between groups. CONCLUSION In this post-hoc analysis of the ARISE trial, early antimicrobial therapy was associated with increased illness severity, but 90-day adjusted mortality was not reduced.

Abstract
BACKGROUND The optimal dosing of antibiotics in critically ill patients receiving renal replacement therapy (RRT) remains unclear. In this study, we describe the variability in RRT techniques and antibiotic dosing in critically ill patients receiving RRT and relate observed trough antibiotic concentrations to optimal targets. METHODS We performed a prospective, observational, multinational, pharmacokinetic study in 29 intensive care units from 14 countries. We collected demographic, clinical, and RRT data. We measured trough antibiotic concentrations of meropenem, piperacillin-tazobactam, and vancomycin and related them to high- and low-target trough concentrations. RESULTS We studied 381 patients and obtained 508 trough antibiotic concentrations. There was wide variability (4-8-fold) in antibiotic dosing regimens, RRT prescription, and estimated endogenous renal function. The overall median estimated total renal clearance (eTRCL) was 50 mL/minute (interquartile range [IQR], 35-65) and higher eTRCL was associated with lower trough concentrations for all antibiotics (P < .05). The median (IQR) trough concentration for meropenem was 12.1 mg/L (7.9-18.8), piperacillin was 78.6 mg/L (49.5-127.3), tazobactam was 9.5 mg/L (6.3-14.2), and vancomycin was 14.3 mg/L (11.6-21.8). Trough concentrations failed to meet optimal higher limits in 26%, 36%, and 72% and optimal lower limits in 4%, 4%, and 55% of patients for meropenem, piperacillin, and vancomycin, respectively. CONCLUSIONS In critically ill patients treated with RRT, antibiotic dosing regimens, RRT prescription, and eTRCL varied markedly and resulted in highly variable antibiotic concentrations that failed to meet therapeutic targets in many patients.

Abstract
BACKGROUND Ganciclovir (GCV) and valganciclovir (VGCV) are the first-line agents used to prevent and treat cytomegalovirus (CMV) infection in allogeneic haematopoietic stem cell transplant (alloHCT) patients. OBJECTIVE The aim of this work was to describe available data for the clinical pharmacokinetics, pharmacodynamics and toxicodynamics of GCV and VGCV and the potential of a therapeutic drug monitoring strategy to improve outcomes in the alloHCT population. METHODS We systematically reviewed the pharmacokinetics (dose-exposure), pharmacodynamics (exposure-efficacy) and toxicodynamics (exposure-toxicity) of GCV and VGCV in alloHCT patients with CMV infection. Studies including alloHCT patients treated for CMV infection reporting the pharmacokinetics, pharmacodynamics and toxicodynamics of GCV or VGCV were searched for using the PUBMED and EMBASE databases from 1946 to 2019. Only studies involving participants > 12 years of age and available in the English language were included. RESULTS A total of 179 patients were included in the 14 studies that met the inclusion criteria, of which 6 examined GCV pharmacokinetics only, while 8 also examined GCV pharmacodynamics and toxicodynamics. Reported pharmacokinetic parameters showed considerable interpatient variability and were different from other populations, such as solid organ transplant and human immunodeficiency virus-infected patients. Only one study found a correlation between neutropenia and elevated peak and trough GCV concentrations, with no other significant pharmacodynamic and toxicodynamic relationships identified. While therapeutic drug monitoring of GCV is performed in some institutions, no association between GCV therapeutic drug monitoring and clinical outcomes was identified. CONCLUSION Further studies of the pharmacokinetics, pharmacodynamics and toxicodynamics of GCV/VGCV in alloHCT patients are required to identify a more robust therapeutic range and to subsequently quantify the potential value of therapeutic drug monitoring of GCV/VGCV in the alloHCT population.

Abstract
BACKGROUND International guidelines recommend critically ill adults receive more protein than most receive. We aimed to establish the feasibility of a trial to evaluate whether feeding protein to international recommendations would improve outcomes, in which 1 group received protein doses representative of international guideline recommendations (high protein) and the other received doses similar to usual practice. METHODS We conducted a prospective, randomized, blinded, parallel-group, feasibility trial across 6 intensive care units. Critically ill, mechanically ventilated adults expected to receive enteral nutrition (EN) for ≥2 days were randomized to receive EN containing 63 or 100 g/L protein for ≤28 days. Data are mean (SD) or median (interquartile range). RESULTS The recruitment rate was 0.35 (0.13) patients per day, with 120 patients randomized and data available for 116 (n = 58 per group). Protein delivery was greater in the high-protein group (1.52 [0.52] vs 0.99 [0.27] grams of protein per kilogram of ideal body weight per day; difference, 0.53 [95% CI, 0.38-0.69] g/kg/d protein), with no difference in energy delivery (difference, -26 [95% CI, -190 to 137] kcal/kg/d). There were no between-group differences in the duration of feeding (8.7 [7.3] vs 8.1 [6.3] days), and blinding of the intervention was confirmed. There were no differences in clinical outcomes, including 90-day mortality (14/55 [26%] vs 15/56 [27%]; risk difference, -1.3% [95% CI, -17.7% to 15.0%]). CONCLUSION Conducting a multicenter blinded trial is feasible to compare protein delivery at international guideline-recommended levels with doses similar to usual care during critical illness.

Abstract
AIMS To evaluate the effect of energy-dense vs routine enteral nutrition on day-90 mortality by ethnic group in critically ill adults. METHODS Pre-planned subgroup analysis of the 1,257 New Zealanders in a 4,000-participant randomised trial comparing energy-dense enteral nutrition (1.5kcal/mL) with routine enteral nutrition (1kcal/mL) in mechanically ventilated intensive care unit (ICU) patients. The primary purpose of this analysis was to evaluate responses to study treatment by ethnic group (European, Māori, and Pacific Peoples) using ethnicity data recorded in the clinical records. The secondary purpose was to compare the characteristics and outcomes of patients by ethnic group. The primary outcome was day-90 mortality. RESULTS Among 1,138 patients included in the primary outcome analysis, 165 of 569 (29.0%) assigned to energy-dense nutrition and 156 of 569 patients (27.4%) assigned to routine nutrition died by day 90 (odds ratio; 1.06; 95% CI, 0.92-1.22). There was no statistically significant interaction between treatment allocation and ethnicity with respect to day-90 mortality. Day-90 mortality rates did not vary statistically significantly by ethnic group. CONCLUSIONS Among mechanically ventilated adults in New Zealand ICUs, the effect on day-90 mortality of energy-dense vs routine enteral nutrition did not vary by ethnicity.

Abstract
Rationale: The long-term effects of delivering approximately 100% of recommended calorie intake via the enteral route during critical illness compared with a lesser amount of calories are unknown.Objectives: Our hypotheses were that achieving approximately 100% of recommended calorie intake during critical illness would increase quality-of-life scores, return to work, and key life activities and reduce death and disability 6 months later.Methods: We conducted a multicenter, blinded, parallel group, randomized clinical trial, with 3,957 mechanically ventilated critically ill adults allocated to energy-dense (1.5 kcal/ml) or routine (1.0 kcal/ml) enteral nutrition.Measurements and Main Results: Participants assigned energy-dense nutrition received more calories (percent recommended energy intake, mean [SD]; energy-dense: 103% [28] vs. usual: 69% [18]). Mortality at Day 180 was similar (560/1,895 [29.6%] vs. 539/1,920 [28.1%]; relative risk 1.05 [95% confidence interval, 0.95-1.16]). At a median (interquartile range) of 185 (182-193) days after randomization, 2,492 survivors were surveyed and reported similar quality of life (EuroQol five dimensions five-level quality-of-life questionnaire visual analog scale, median [interquartile range]: 75 [60-85]; group difference: 0 [95% confidence interval, 0-0]). Similar numbers of participants returned to work with no difference in hours worked or effectiveness at work (n = 818). There was no observed difference in disability (n = 1,208) or participation in key life activities (n = 705).Conclusions: The delivery of approximately 100% compared with 70% of recommended calorie intake during critical illness does not improve quality of life or functional outcomes or increase the number of survivors 6 months later.

Abstract
Enteral energy delivery above requirements (overfeeding) is believed to cause adverse effects during critical illness, but the literature supporting this is limited. We aimed to quantify the reported frequency and clinical sequelae of energy overfeeding with enterally delivered nutrition in critically ill adult patients. A systematic search of MEDLINE, EMBASE, and CINAHL from conception to November 28, 2018, identified clinical studies of nutrition interventions in enterally fed critically ill adults that reported overfeeding in 1 or more study arms. Overfeeding was defined as energy delivery > 2000 kcal/d, > 25 kcal/kg/d, or ≥ 110% of energy prescription. Data were extracted on methodology, demographics, prescribed and delivered nutrition, clinical variables, and predefined outcomes. Cochrane "Risk of Bias" tool was used to assess the quality of randomized controlled trials (RCTs). Eighteen studies were included, of which 10 were randomized (n = 4386 patients) and 8 were nonrandomized (n = 223). Only 4 studies reported a separation in energy delivery between treatment groups whereby 1 arm met the definition of overfeeding, which reported no between-group differences in mortality, infectious complications, or ventilatory support. Overfeeding was associated with increased insulin administration (median 3 [interquartile range: 0-41.8] vs 0 [0-30.6] units/d) and upper-gastrointestinal intolerance in 1 large RCT and with duration of antimicrobial therapy in a small RCT. There are limited high-quality data to determine the impact of energy overfeeding of critically ill patients by the enteral route; however, based on available evidence, overfeeding does not appear to affect mortality or other important clinical outcomes.

Abstract
Background Piperacillin is a β-lactam penicillin antibiotic commonly used for the empirical therapy of sepsis and other hospital-acquired infections. However, knowledge regarding the effect of sustained low-efficiency diafiltration (SLED-f), a technique increasingly being used in ICUs, on piperacillin pharmacokinetics (PK) and dosing in critically ill patients is lacking. Objectives To describe the PK of piperacillin during SLED-f and compare the results with those reported for other forms of renal replacement therapies. Methods Serial blood samples were collected at pre- and post-filter ports within the SLED-f circuit during SLED-f in one session and from an arterial catheter during sampling without SLED-f. Piperacillin concentrations were measured using a validated chromatography method. Non-compartmental PK analysis of the data was performed. Results The median clearance and area under the concentration-time curve during SLED-f were 6 L/h and 532 mg·h/L, respectively. Fifty-eight percent of piperacillin was cleared by a single SLED-f session (6 h) compared with previous reports of 30%-45% clearance by a 3.5 h intermittent haemodialysis session. Clearance, half-life and area under the concentration-time curve during SLED-f obtained from this study were comparable with those reported in the post-dilution mode of continuous veno-venous haemodiafiltration studies. Conclusions As it can be challenging to accurately predict when SLED-f will be initiated in the critically ill, a maintenance dose of at least 4 g every 12 h with at least a 2 g replacement dose post-SLED-f would be a practical approach to piperacillin dosing in ICU patients with anuria receiving SLED-f with a duration similar to the current study.

Abstract
BACKGROUND The effect of delivering nutrition at different calorie levels during critical illness is uncertain, and patients typically receive less than the recommended amount. METHODS We conducted a multicenter, double-blind, randomized trial, involving adults undergoing mechanical ventilation in 46 Australian and New Zealand intensive care units (ICUs), to evaluate energy-dense (1.5 kcal per milliliter) as compared with routine (1.0 kcal per milliliter) enteral nutrition at a dose of 1 ml per kilogram of ideal body weight per hour, commencing at or within 12 hours of the initiation of nutrition support and continuing for up to 28 days while the patient was in the ICU. The primary outcome was all-cause mortality within 90 days. RESULTS There were 3957 patients included in the modified intention-to-treat analysis (1971 in the 1.5-kcal group and 1986 in the 1.0-kcal group). The volume of enteral nutrition delivered during the trial was similar in the two groups; however, patients in the 1.5-kcal group received a mean (±SD) of 1863±478 kcal per day as compared with 1262±313 kcal per day in the 1.0-kcal group (mean difference, 601 kcal per day; 95% confidence interval [CI], 576 to 626). By day 90, a total of 523 of 1948 patients (26.8%) in the 1.5-kcal group and 505 of 1966 patients (25.7%) in the 1.0-kcal group had died (relative risk, 1.05; 95% CI, 0.94 to 1.16; P=0.41). The results were similar in seven predefined subgroups. Higher calorie delivery did not affect survival time, receipt of organ support, number of days alive and out of the ICU and hospital or free of organ support, or the incidence of infective complications or adverse events. CONCLUSIONS In patients undergoing mechanical ventilation, the rate of survival at 90 days associated with the use of an energy-dense formulation for enteral delivery of nutrition was not higher than that with routine enteral nutrition.

Abstract
Vancomycin is a commonly prescribed antibiotic in the intensive care unit. However, there are limited data describing its distribution into the interstitial fluid (ISF) of tissues. The aim of this study was to describe the plasma and tissue ISF population pharmacokinetics of vancomycin in critically ill patients with sepsis. Serial vancomycin blood and ISF samples were collected at pre-specified time intervals in critically ill patients with sepsis. ISF sampling occurred using a subcutaneously inserted microdialysis catheter. Bioanalysis was undertaken using a validated spectrometric assay method. Population pharmacokinetic analysis was performed using Pmetrics®. Seven patients were recruited and pharmacokinetic data were available for six of them. The median (interquartile range) age, weight, Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA) score and measured creatinine clearance (CLCr) were 55 (44-67) years, 85 (81-102) kg, 20 (16-29), 5 (4-8) and 90 (83-98) mL/min, respectively. Vancomycin pharmacokinetics was best described by a three-compartment linear model. Measured CLCr (on vancomycin clearance) and weight (on volume of distribution of the central compartment) were the only patient covariates that improved the model fit. Coefficients of variation for the vancomycin rate constants into and out of the peripheral and tissue ISF compartments were also high, ranging from 47% to 134%. There is significant variability of vancomycin distribution into tissue ISF, which it was not possible to explain with patient characteristics.

Abstract
BACKGROUND Reliable assessment and documentation of weight and height are essential for the accurate delivery of many critical care interventions. METHODS We conducted a 3-month retrospective, cross-sectional, single-centre audit to determine the prevalence of weight and height documentation in the clinical records of patients admitted to the intensive care unit (ICU) for the period from 3 months prior to hospital admission up to hospital discharge. RESULTS One hundred forty-one index ICU admissions were identified from October-December 2015 with 138 medical records available for analysis. Median (interquartile range) age was 64.5 (50.8-75.3) years, the majority were male (60.9%, 84/138), and the ICU admission Acute Physiology and Chronic Health Evaluation II score was 19.0 (14.0-25.0). Overall, weight and height were recorded in 90 (65.2%) and 63 (45.6%) patients, respectively. For elective postoperative admissions (n = 20), weight and height were recorded in 20 (100%) and 19 (95%) patients. For emergency medical and surgical admissions, 70 (59.3%) and 44 (37.2%) patients had weight and height recorded in both the 3-month period prior to hospital admission and the in-hospital period. A moderate, positive correlation was shown, r = 0.55, P < 0.001, with a longer hospital length of stay being associated with a greater number of weight and height records for each patient. In the emergency patient cohort, 81.7% (n = 215/263) of weight- and/or height-based interventions occurred before or during the ICU admission, of which 69.9% (n = 184/263) required consideration of ideal body weight. CONCLUSION Measurement and medical record documentation of weight and height is infrequently performed in ICU patients. Given the clinical requirement for accurate measurement and documentation, further research to understand the barriers to perform and document this important process of care is necessary.

Abstract
STUDY OBJECTIVE The influence of the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) on the conduct of future sepsis research is unknown. We seek to examine the potential effect of the new definitions on the identification and outcomes of patients enrolled in a sepsis trial. METHODS This was a post hoc analysis of the Australasian Resuscitation in Sepsis Evaluation (ARISE) trial of early goal-directed therapy that recruited 1,591 adult patients presenting to the emergency department (ED) with early septic shock diagnosed by greater than or equal to 2 systemic inflammatory response syndrome criteria and either refractory hypotension or hyperlactatemia. The proportion of participants who would have met the Sepsis-3 criteria for quick Sequential Organ Failure Assessment (qSOFA) score, sepsis (an increased Sequential Organ Failure Assessment score ≥2 because of infection) and septic shock before randomization, their baseline characteristics, interventions delivered, and mortality were determined. RESULTS There were 1,139 participants who had a qSOFA score of greater than or equal to 2 at baseline (71.6% [95% confidence interval {CI} 69.4% to 73.8%]). In contrast, 1,347 participants (84.7% [95% CI 82.9% to 86.4%]) met the Sepsis-3 criteria for sepsis. Only 1,010 participants were both qSOFA positive and met the Sepsis-3 criteria for sepsis (63.5% [95% CI 61.1% to 65.8%]). The Sepsis-3 definition for septic shock was met at baseline by 203 participants (12.8% [95% CI 11.2% to 14.5%]), of whom 175 (86.2% [95% CI 81.5% to 91.0%]) were also qSOFA positive. Ninety-day mortality for participants fulfilling the Sepsis-3 criteria for sepsis and septic shock was 20.4% (95% CI 18.2% to 22.5%) (274/1,344) and 29.6% (95% CI 23.3% to 35.8% [60/203]) versus 9.4% (95% CI 5.8% to 13.1%) (23/244) and 17.1% (95% CI 15.1% to 19.1% [237/1,388]), respectively, for participants not meeting the criteria (risk differences 11.0% [95% CI 6.2% to 14.8%] and 12.5% [95% CI 6.3% to 19.4%], respectively). CONCLUSION Most ARISE participants did not meet the Sepsis-3 definition for septic shock at baseline. However, the majority fulfilled the new sepsis definition and mortality was higher than for participants not fulfilling the criteria. A quarter of participants meeting the new sepsis definition did not fulfill the qSOFA screening criteria, potentially limiting its utility as a screening tool for sepsis trials with patients with suspected infection in the ED. The implications of the new definitions for patients not eligible for recruitment into the ARISE trial are unknown.

Abstract
The capacity to measure the impact of an intervention on long-term functional outcomes might be improved if research methodology reflected our clinical approach, which is to individualise goals of care to what is achievable for each patient. The objective of this multicentre inception cohort study was to evaluate the feasibility of rapidly and accurately categorising patients, who were eligible for simulated enrolment into a clinical trial, into unique categories based on premorbid function. Once a patient met eligibility criteria a rapid 'baseline assessment' was conducted to categorise patients into one of eight specified groups. A subsequent 'gold standard' assessment was made by an independent blinded assessor once patients had recovered sufficiently to allow such an assessment to occur. Accuracy was predefined as agreement in >80% of assessments. One hundred and twenty-two patients received a baseline assessment and 104 (85%) were categorised to a unique category. One hundred and six patients survived to have a gold standard assessment performed, with 100 (94%) assigned to a unique category. Ninety-two patients had both a baseline and gold standard assessment, and these agreed in 65 (71%) patients. It was not feasible to rapidly and accurately categorise patients according to premorbid function.

Abstract
BACKGROUND After a single-center trial and observational studies suggesting that early, goal-directed therapy (EGDT) reduced mortality from septic shock, three multicenter trials (ProCESS, ARISE, and ProMISe) showed no benefit. This meta-analysis of individual patient data from the three recent trials was designed prospectively to improve statistical power and explore heterogeneity of treatment effect of EGDT. METHODS We harmonized entry criteria, intervention protocols, outcomes, resource-use measures, and data collection across the trials and specified all analyses before unblinding. After completion of the trials, we pooled data, excluding the protocol-based standard-therapy group from the ProCESS trial, and resolved residual differences. The primary outcome was 90-day mortality. Secondary outcomes included 1-year survival, organ support, and hospitalization costs. We tested for treatment-by-subgroup interactions for 16 patient characteristics and 6 care-delivery characteristics. RESULTS We studied 3723 patients at 138 hospitals in seven countries. Mortality at 90 days was similar for EGDT (462 of 1852 patients [24.9%]) and usual care (475 of 1871 patients [25.4%]); the adjusted odds ratio was 0.97 (95% confidence interval, 0.82 to 1.14; P=0.68). EGDT was associated with greater mean (±SD) use of intensive care (5.3±7.1 vs. 4.9±7.0 days, P=0.04) and cardiovascular support (1.9±3.7 vs. 1.6±2.9 days, P=0.01) than was usual care; other outcomes did not differ significantly, although average costs were higher with EGDT. Subgroup analyses showed no benefit from EGDT for patients with worse shock (higher serum lactate level, combined hypotension and hyperlactatemia, or higher predicted risk of death) or for hospitals with a lower propensity to use vasopressors or fluids during usual resuscitation. CONCLUSIONS In this meta-analysis of individual patient data, EGDT did not result in better outcomes than usual care and was associated with higher hospitalization costs across a broad range of patient and hospital characteristics.

Abstract
BACKGROUND AND OBJECTIVE High serum osmolarity has been shown to be lung protective. There is lack of clinical studies evaluating the impact on outcomes such as mortality. We aimed to examine the effect of serum osmolarity on intensive care unit (ICU) mortality in critically ill patients METHODS: Data from January 2000 to December 2012 was accessed using the Australian and New Zealand Intensive Care Society (ANZICS) Clinical Outcomes and Resource Evaluation (CORE) database. A total of 509 180 patients were included. Serum osmolarity was calculated from data during the first 24 h of ICU admission. Predefined subgroups (Acute Physiology and Chronic Health Evaluation (APACHE) III diagnostic codes), including patients with acute pulmonary diagnoses, were examined. The effect of serum osmolarity on ICU mortality was assessed with analysis adjusted for illness severity (serum sodium, glucose and urea component removed) and year of admission. Results are presented as OR (95% CI) referenced against a serum osmolarity of 290-295 mmol/L. RESULTS The ICU mortality was elevated at each extremes of serum osmolarity (U-shaped relationship). A similar relationship was found in various subgroups, with the exception of patients with pulmonary diagnoses in whom ICU mortality was not influenced by high serum osmolarity and was different from other non-pulmonary subgroups (P < 0.01). Any adverse associations with high serum osmolarity in pulmonary patients were confined to patients with a PaO2 /FiO2 ratio > 200. CONCLUSION High admission serum osmolarity was not associated with increased odds for ICU death in pulmonary patients, unlike other subgroup of patients, and could be a potential area for future interventional therapy.

Abstract
Augmenting energy delivery during the acute phase of critical illness may reduce mortality and improve functional outcomes. The objective of this sub-study was to evaluate the effect of early augmented enteral nutrition (EN) during critical illness, on outcomes one year later. We performed prospective longitudinal evaluation of study participants, initially enrolled in The Augmented versus Routine approach to Giving Energy Trial (TARGET), a feasibility study that randomised critically ill patients to 1.5 kcal/ml (augmented) or 1.0 kcal/ml (routine) EN administered at the same rate for up to ten days, who were alive at one year. One year after randomisation Short Form-36 version 2 (SF-36v2) and EuroQol-5D-5L quality of life surveys, and employment status were assessed via telephone survey. At one year there were 71 survivors (1.5 kcal/ml 38 versus 1.0 kcal/ml 33; P=0.55). Thirty-nine (55%) patients consented to this follow-up study and completed the surveys (n = 23 and 16, respectively). The SF-36v2 physical and mental component summary scores were below normal population means but were similar in 1.5 kcal/ml and 1.0 kcal/ml groups (P=0.90 and P=0.71). EuroQol-5D-5L data were also comparable between groups (P=0.70). However, at one-year follow-up, more patients who received 1.5 kcal/ml were employed (7 versus 2; P=0.022). The delivery of 1.5 kcal/ml for a maximum of ten days did not affect self-rated quality of life one year later.

Abstract
OBJECTIVES To determine the effect of calorie delivery on hospital mortality among critically ill adults receiving enteral nutrition (EN). Secondary outcomes included the effect of calorie delivery on intensive care unit and hospital length of stay (LOS), duration of mechanical ventilation (MV) and incidence of new-onset pneumonia. METHODS We identified randomised clinical trials of EN, with or without supplemental parenteral nutrition (PN), involving adult ICU patients for whom mortality data were available, and when there was a significant difference in calorie supplementation between intervention arms (P < 0.05). We searched English language electronic databases (1946-2014), bibliographies of nutrition society guidelines and high-impact nutrition and critical care journals. We calculated summary odds ratio (OR) estimates and 95% confidence intervals using a random effects estimator, and used meta-regression to assess the effect on mortality of average calories delivered. RESULTS Of 1545 articles identified, 16 eligible studies involving 3473 patients were included. Five studies involved supplemental PN. Mean calorie delivery ranged from 126 kcal/day (SD, 115 kcal/day) to 2086 kcal/day (SD, 460 kcal/day). Mortality was 26.0% in the lower calorie delivery group and 26.5% in the higher calorie delivery group. There was no effect of increased calorie delivery on mortality (OR, 1.02; 95% CI , 0.85-1.24; P = 0.27; I2 = 16.3%). ICU and hospital LOS and incidence of newonset pneumonia did not differ between groups. Duration of MV was decreased with lower calorie delivery (weighted mean difference, 2.92 days; 95% CI, -4.49 to -1.35 days; P < 0.001; I2 = 14.7%). Meta-regression analysis did not show an overall effect on mortality of average calories delivered (P = 0.73; I2 = 40.8%). CONCLUSION Delivery of increased calories via the enteral route, with or without supplemental PN, was not associated with a survival benefit.

Abstract
PURPOSE To determine whether early goal-directed therapy (EGDT) reduces mortality compared with other resuscitation strategies for patients presenting to the emergency department (ED) with septic shock. METHODS Using a search strategy of PubMed, EmBase and CENTRAL, we selected all relevant randomised clinical trials published from January 2000 to January 2015. We translated non-English papers and contacted authors as necessary. Our primary analysis generated a pooled odds ratio (OR) from a fixed-effect model. Sensitivity analyses explored the effect of including non-ED studies, adjusting for study quality, and conducting a random-effects model. Secondary outcomes included organ support and hospital and ICU length of stay. RESULTS From 2395 initially eligible abstracts, five randomised clinical trials (n = 4735 patients) met all criteria and generally scored high for quality except for lack of blinding. There was no effect on the primary mortality outcome (EGDT: 23.2% [495/2134] versus control: 22.4% [582/2601]; pooled OR 1.01 [95% CI 0.88-1.16], P = 0.9, with heterogeneity [I(2) = 57%; P = 0.055]). The pooled estimate of 90-day mortality from the three recent multicentre studies (n = 4063) also showed no difference [pooled OR 0.99 (95% CI 0.86-1.15), P = 0.93] with no heterogeneity (I(2) = 0.0%; P = 0.97). EGDT increased vasopressor use (OR 1.25 [95% CI 1.10-1.41]; P < 0.001) and ICU admission [OR 2.19 (95% CI 1.82-2.65); P < 0.001]. Including six non-ED randomised trials increased heterogeneity (I(2) = 71%; P < 0.001) but did not change overall results [pooled OR 0.94 (95% CI 0.82 to 1.07); P = 0.33]. CONCLUSION EGDT is not superior to usual care for ED patients with septic shock but is associated with increased utilisation of ICU resources.

Abstract
OBJECTIVES The objectives of this study were to describe piperacillin exposure in febrile neutropenia patients and determine whether therapeutic drug monitoring (TDM) can be used to increase the achievement of pharmacokinetic (PK)/pharmacodynamic (PD) targets. METHODS In a prospective randomized controlled study (Australian New Zealand Registry, ACTRN12615000086561), patients were subjected to TDM for 3 consecutive days. Dose was adjusted in the intervention group to achieve a free drug concentration above the MIC for 100% of the dose interval (100% fT>MIC), which was also the primary outcome measure. The secondary PK/PD target was 50% fT>MIC. Duration of fever and days to recovery from neutropenia were recorded. RESULTS Thirty-two patients were enrolled. Initially, patients received 4.5 g of piperacillin/tazobactam every 8 h or every 6 h along with gentamicin co-therapy in 30/32 (94%) patients. At the first TDM, 7/32 (22%) patients achieved 100% fT>MIC and 12/32 (38%) patients achieved 50% fT>MIC. Following dose adjustment, 11/16 (69%) of intervention patients versus 3/16 (19%) of control patients (P = 0.012) attained 100% fT>MIC, and 15/16 (94%) of intervention patients versus 5/16 (31%) of control patients (P = 0.001) achieved 50% fT>MIC. After the third TDM, the proportion of patients attaining 100% fT>MIC improved from a baseline 3/16 (19%) to 11/15 (73%) in the intervention group, while it declined from 4/16 (25%) to 1/15 (7%) in the control group. No difference was noted in the duration of fever and days to recovery from neutropenia. CONCLUSIONS Conventional doses of piperacillin/tazobactam may not offer adequate piperacillin exposure in febrile neutropenic patients. TDM provides useful feedback of dosing adequacy to guide dose optimization.

Abstract
Acute kidney injury is a common complication in critically ill patients, and hybrid techniques including sustained low-efficiency dialysis/diafiltration (SLED-f) are being increasingly utilised in intensive care units. Most fungal infections occur in the interstitial fluid (ISF) of tissues and successful treatment of a fungal infection relies on the ability of an antifungal agent to achieve adequate concentrations at the site of infection. Tissue distribution of antimicrobials is impaired in critically ill patients owing to a variety of disease-related physiological changes, e.g. sepsis. Fluconazole is a widely used antifungal agent used to treat Candida spp. infections in critically ill patients. The implications for ISF concentrations of enhanced elimination during renal replacement therapy have not yet been reported for fluconazole. The aim of this single-patient case report was to describe the influence of SLED-f on subcutaneous (SC) ISF concentrations of fluconazole and the implications for achieving pharmacokinetic/pharmacodynamic targets. Serial blood and ISF samples were collected at pre- and post-filter ports within the SLED-f circuit and subcutaneously inserted microdialysis probe, respectively. Fluconazole concentrations were measured using a validated chromatography method. The SC ISF-to-plasma partition coefficient of fluconazole in this patient was 0.91, indicating rapid equilibrium. SC ISF fluconazole concentrations consistently decreased after initiating SLED-f. The majority of the fluconazole was eliminated from the SC ISF as a result of redistribution. Considering the extensive tissue re-distribution of fluconazole and observed elimination from tissue compartments, higher doses may be required to treat deep-seated fungal infections.

Abstract
BACKGROUND Large positive sodium balances, independent of fluid balance, may lead to expanded extracellular fluid volumes and adverse clinical outcomes in the critically ill, including impaired oxygenation. OBJECTIVES To estimate sodium and fluid balances in critically ill patients needing invasive mechanical ventilation (MV) for more than 48 hours and to evaluate the relationship between fluid balance, sodium balance and respiratory function (PaO2/FiO2 ratio and length of MV). DESIGN AND SETTING A prospective, observational study of 50 patients on MV in four tertiary intensive care units. MAIN OUTCOME MEASURES Daily sodium and fluid input and output, biochemistry, haemodynamic variables, oxygenation (PaO2/FiO2) and steroid and vasopressor administration were recorded for 3 days after study enrolment. Outcome data included the duration of invasive MV, ICU and hospital mortality and ICU and hospital lengths of stay. RESULTS Fifty patients (33 men [66%]) with a mean age of 62.8 years (standard deviation, 14.6 years) and a median admission Acute Physiology and Chronic Health Evaluation III score of 82 (interquartile range [IQR], 61-99) were studied. By Day 3 after enrolment, the median cumulative fluid balance was 2668 mL (IQR, 875-3507 mL) and the cumulative sodium balance was +717 mmol (IQR, +422 to +958 mmol). Intravenous steroids and the presence of shock led to a lower daily sodium excretion (P=0.004 and P=0.01, respectively). A positive sodium balance was associated with a reduction in the next day's PaO2/FiO2 ratio (ρ=-0.36, P=0.001) and an increased length of MV (linear regression analysis, P<0.01). The cumulative fluid balance was not associated with either parameter. CONCLUSIONS The cumulative positive sodium balance, not the cumulative positive fluid balance, is associated with respiratory dysfunction and an increased length of MV.

Abstract
BACKGROUND Early goal-directed therapy (EGDT) has been endorsed in the guidelines of the Surviving Sepsis Campaign as a key strategy to decrease mortality among patients presenting to the emergency department with septic shock. However, its effectiveness is uncertain. METHODS In this trial conducted at 51 centers (mostly in Australia or New Zealand), we randomly assigned patients presenting to the emergency department with early septic shock to receive either EGDT or usual care. The primary outcome was all-cause mortality within 90 days after randomization. RESULTS Of the 1600 enrolled patients, 796 were assigned to the EGDT group and 804 to the usual-care group. Primary outcome data were available for more than 99% of the patients. Patients in the EGDT group received a larger mean (±SD) volume of intravenous fluids in the first 6 hours after randomization than did those in the usual-care group (1964±1415 ml vs. 1713±1401 ml) and were more likely to receive vasopressor infusions (66.6% vs. 57.8%), red-cell transfusions (13.6% vs. 7.0%), and dobutamine (15.4% vs. 2.6%) (P<0.001 for all comparisons). At 90 days after randomization, 147 deaths had occurred in the EGDT group and 150 had occurred in the usual-care group, for rates of death of 18.6% and 18.8%, respectively (absolute risk difference with EGDT vs. usual care, -0.3 percentage points; 95% confidence interval, -4.1 to 3.6; P=0.90). There was no significant difference in survival time, in-hospital mortality, duration of organ support, or length of hospital stay. CONCLUSIONS In critically ill patients presenting to the emergency department with early septic shock, EGDT did not reduce all-cause mortality at 90 days.

Abstract
Fluconazole is a widely used antifungal agent in critically ill patients. It is predominantly (60-80%) excreted unchanged in urine. Sustained low-efficiency diafiltration (SLED-f) is increasingly being utilised in critically ill patients because of its practical advantages over continuous renal replacement therapy. To date, the effect of SLED-f on fluconazole pharmacokinetics and dosing has not been studied. The objective of this study was to describe the pharmacokinetics of fluconazole in critically ill patients with acute kidney injury receiving SLED-f and to compare this with other forms of renal replacement therapy. Serial blood samples were collected at pre- and post-filter ports within the SLED-f circuit during SLED-f and from an arterial catheter before and after SLED-f from three patients during one session. Fluconazole concentrations were measured using a validated chromatography method. Median clearance (CL) and 24-h area under the concentration-time curve (AUC0-24) were 2.1L/h and 152 mg·h/L, respectively, whilst receiving SLED-f. Moreover, 72% of fluconazole was cleared by a single SLED-f session (6h) compared with previous reports of 33-38% clearance by a 4-h intermittent haemodialysis session. CL and AUC0-24 were comparable with previous observations in a pre-dilution mode of continuous venovenous haemodiafiltration. The observed rebound concentration of fluconazole post SLED-f was <2%. Although a definitive dosing recommendation is not possible due to the small patient number, it is clear that doses >200mg daily are likely to be required to achieve the PK/PD target for common pathogens because of significant fluconazole clearance by SLED-f.

Abstract
BACKGROUND Critically ill patients typically receive ∼60% of estimated calorie requirements. OBJECTIVES We aimed to determine whether the substitution of a 1.5-kcal/mL enteral nutrition solution for a 1.0-kcal/mL solution resulted in greater calorie delivery to critically ill patients and establish the feasibility of conducting a multicenter, double-blind, randomized trial to evaluate the effect of an increased calorie delivery on clinical outcomes. DESIGN A prospective, randomized, double-blind, parallel-group, multicenter study was conducted in 5 Australian intensive care units. One hundred twelve mechanically ventilated patients expected to receive enteral nutrition for ≥2 d were randomly assigned to receive 1.5 (n = 57) or 1.0 (n = 55) kcal/mL enteral nutrition solution at a rate of 1 mL/kg ideal body weight per hour for 10 d. Protein and fiber contents in the 2 solutions were equivalent. RESULTS The 2 groups had similar baseline characteristics (1.5 compared with 1.0 kcal/mL). The mean (±SD) age was 56.4 ± 16.8 compared with 56.5 ± 16.1 y, 74% compared with 75% were men, and the Acute Physiology and Chronic Health Evaluation II score was 23 ± 9.1 compared with 22 ± 8.9. The groups received similar volumes of enteral nutrition solution [1221 mL/d (95% CI: 1120, 1322 mL/d) compared with 1259 mL/d (95% CI: 1143, 1374 mL/d); P = 0.628], which led to a 46% increase in daily calories in the group given the 1.5-kcal/mL solution [1832 kcal/d (95% CI: 1681, 1984 kcal/d) compared with 1259 kcal/d (95% CI: 1143, 1374 kcal/d); P < 0.001]. The 1.5-kcal/mL solution was not associated with larger gastric residual volumes or diarrhea. In this feasibility study, there was a trend to a reduced 90-d mortality in patients given 1.5 kcal/mL [11 patients (20%) compared with 20 patients (37%); P = 0.057]. CONCLUSIONS The substitution of a 1.0- with a 1.5-kcal/mL enteral nutrition solution administered at the same rate resulted in a 46% greater calorie delivery without adverse effects. The results support the conduct of a large-scale trial to evaluate the effect of increased calorie delivery on clinically important outcomes in the critically ill.

Abstract
BACKGROUND Because increased serum osmolarity may be lung protective, we hypothesized that increased mortality associated with increased serum sodium would be ameliorated in critically ill patients with an acute respiratory diagnosis. METHODS Data collected within the first 24 hours of intensive care unit (ICU) admission were accessed using ANZICS CORE database. From January 2000 to December 2010, 436,209 patients were assessed. Predefined subgroups including patients with acute respiratory diagnoses were examined. The effect of serum sodium on ICU mortality was assessed with analysis adjusted for illness severity and year of admission. Results are presented as odds ratio (95% confidence interval) referenced against a serum sodium range of 135 to 144.9 mmol/L. RESULTS Overall ICU mortality was increased at each extreme of dysnatremia (U-shaped relationship). A similar trend was found in various subgroups, with the exception of patients with respiratory diagnoses where ICU mortality was not influenced by high serum sodium (odds ratio, 1.3 [0.7-1.2]) and was different from other patient groups (P<.01). Any adverse associations with hypernatremia in respiratory patients were confined to those with arterial pressure of oxygen (PaO2)/fraction of inspired oxygen (Fio2) ratios of greater than 200. CONCLUSION High admission serum sodium is associated with increased odds for ICU death, except in respiratory patients.

Abstract
OBJECTIVE Dysnatraemia and a positive fluid balance are associated with poor outcomes in paediatric intensive care units (PICUs). Our objective was to determine sodium intake and the total daily fluid balance in children in the PICU. METHOD A single-day point prevalence study in 10 Australian and New Zealand PICUs. Patients on free oral diets were excluded. Demographics, 24-hour fluid balance and sodium intake (enteral and parenteral sources) were recorded. RESULTS We enrolled 65 patients; 15 were excluded due to having a free oral intake and two patients had incomplete data, leaving 48 children in the study cohort. The 21 infants had a median age of 4 months (interquartile range [IQR], 1-7 months) and a median bodyweight of 5 kg (IQR, 3.5- 6.1 kg). The 27 children > 1 year had a median age of 3 years (IQR, 1.5-13 years) and a median bodyweight of 17 kg (IQR, 9.5-47.5 kg). Overall, the median sodium administration on the study day was 4.9mmol/kg (IQR, 3.2- 8mmol/kg), median fluid administration was 80.8mL/kg (IQR, 49.8-111.4mL/kg) and median fluid balance was 9mL/kg (IQR, -1.4 to 41 mL/kg). For infants, the median sodium administration was 6mmol/kg (IQR, 3.9-8.1mmol/ kg), and median fluid balance was 20.8mL/kg (IQR, 3.5- 47.2mL/kg). For children > 1 year, the median sodium administration was 3.5mmol/kg (IQR, 3.1-7.8mmol/kg), and median fluid balance was 5.3mL/kg (IQR, -2.7 to 17.7mL/kg). Overall, fluid infusions, boluses and catheter flushes together contributed 46.2% of total sodium administered. Drugs contributed substantially to administered sodium (33.3%), with antibiotics accounting for the majority. Enteral feeds contributed 16.2% to overall administered sodium, and were the major source in patients in the PICU for > 10 days. CONCLUSION Daily sodium intake in children in the PICU is high. The contributions of maintenance and bolus intravenous fluids (most commonly as 0.9% sodium chloride), drug infusions and boluses, including antibiotics, and enteral feeds, are significant.

Abstract
BACKGROUND Inadvertent sodium administration in excess of recommended daily requirements has been reported during routine care of critically ill patients. AIM To determine the amount and sources of sodium administered in Australian and New Zealand intensive care units. DESIGN, SETTING AND PARTICIPANTS Prospective, observational, single-day, point prevalence survey conducted in 46 Australian and New Zealand ICUs on 21 September 2011. All patients present in ICU at 10 am and not receiving an oral diet on the study day were evaluated. Demographic data, ICU admission diagnosis, Acute Physiology and Chronic Health Evaluation (APACHE) II score and sources of sodium administration over the study day were recorded. RESULTS 356 patients (64% male) were enrolled. Mean (SD) age and weight were 58.5 years (18.0 years) and 81.6 kg (24.0 kg), respectively. Mean ICU admission APACHE II score was 20 (SD, 8). Overall median (interquartile range [IQR]) sodium administration was 224.5 mmol (IQR, 144.9-367.6 mmol), or 2.8 mmol/kg (IQR, 1.6-4.7 mmol/kg). Among patients who were on Day 2-10 of their ICU admission on the study day, sodium sources and amounts administered were: i) maintenance or replacement intravenous (IV) infusions, 69.3mmol; 30.9% of all sodium sources; ii) IV fluid boluses, 36.5 mmol; 16.3%; iii) IV drug boluses, 27.6 mmol; 12.3%; iv) enteral nutrition, 26.5 mmol; 11.8%; v) IV drug infusions, 19.3 mmol; 8.6%; vi) IV flushes, 16.6mmol; 7.4%; vii) blood products, 13.5 mmol; 6%; viii) IV antimicrobials, 11.2mmol; 5%; and ix) parenteral nutrition, 4.3 mmol; 1.9%. Factors associated with sodium administration were site (P = 0.04), age (P < 0.001), administered fluid (P = 0.03) and day of ICU stay (P = 0.01) (multiple linear regression). CONCLUSION 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.

Abstract
BACKGROUND The Australasian Resuscitation In Sepsis Evaluation (ARISE) study is an international, multicentre, randomised, controlled trial designed to evaluate the effectiveness of early goal-directed therapy compared with standard care for patients presenting to the ED with severe sepsis. OBJECTIVE In keeping with current practice, and taking into considerations aspects of trial design and reporting specific to non-pharmacologic interventions, this document outlines the principles and methods for analysing and reporting the trial results. The document is prepared prior to completion of recruitment into the ARISE study, without knowledge of the results of the interim analysis conducted by the data safety and monitoring committee and prior to completion of the two related international studies. METHODS The statistical analysis plan was designed by the ARISE chief investigators, and reviewed and approved by the ARISE steering committee. The data collected by the research team as specified in the study protocol, and detailed in the study case report form were reviewed. Information related to baseline characteristics, characteristics of delivery of the trial interventions, details of resuscitation and other related therapies, and other relevant data are described with appropriate comparisons between groups. The primary, secondary and tertiary outcomes for the study are defined, with description of the planned statistical analyses. RESULTS A statistical analysis plan was developed, along with a trial profile, mock-up tables and figures. A plan for presenting baseline characteristics, microbiological and antibiotic therapy, details of the interventions, processes of care and concomitant therapies, along with adverse events are described. The primary, secondary and tertiary outcomes are described along with identification of subgroups to be analysed. CONCLUSION A statistical analysis plan for the ARISE study has been developed, and is available in the public domain, prior to the completion of recruitment into the study. This will minimise analytic bias and conforms to current best practice in conducting clinical trials.

Abstract
BACKGROUND The Australasian Resuscitation in Sepsis Evaluation (ARISE) study is an international, multicentre, randomised, controlled trial designed to evaluate the effectiveness of early goal-directed therapy compared with standard care for patients presenting to the emergency department with severe sepsis. OBJECTIVE In keeping with current practice, and considering aspects of trial design and reporting specific to non-pharmacological interventions, our plan outlines the principles and methods for analysing and reporting the trial results. The document is prepared before completion of recruitment into the ARISE study, without knowledge of the results of the interim analysis conducted by the data safety and monitoring committee and before completion of the two related international studies. METHODS Our statistical analysis plan was designed by the ARISE chief investigators, and reviewed and approved by the ARISE steering committee. We reviewed the data collected by the research team as specified in the study protocol and detailed in the study case report form. We describe information related to baseline characteristics, characteristics of delivery of the trial interventions, details of resuscitation, other related therapies and other relevant data with appropriate comparisons between groups. We define the primary, secondary and tertiary outcomes for the study, with description of the planned statistical analyses. RESULTS We have developed a statistical analysis plan with a trial profile, mock-up tables and figures. We describe a plan for presenting baseline characteristics, microbiological and antibiotic therapy, details of the interventions, processes of care and concomitant therapies and adverse events. We describe the primary, secondary and tertiary outcomes with identification of subgroups to be analysed. CONCLUSION We have developed a statistical analysis plan for the ARISE study, available in the public domain, before the completion of recruitment into the study. This will minimise analytical bias and conforms to current best practice in conducting clinical trials.

Abstract
PURPOSE To describe and compare the design of three independent but collaborating multicenter trials of early goal-directed resuscitation for severe sepsis and septic shock. METHODS We reviewed the three current trials, one each in the USA (ProCESS: protocolized care for early septic shock), Australasia (ARISE: Australasian resuscitation in sepsis evaluation), and the UK (ProMISe: protocolised management in sepsis). We used the 2010 CONSORT (consolidated standards of reporting trials) statement and the 2008 CONSORT extension for trials assessing non-pharmacologic treatments to describe and compare the underlying rationale, commonalities, and differences. RESULTS All three trials conform to CONSORT guidelines, address the same fundamental questions, and share key design elements. Each trial is a patient-level, equal-randomized, parallel-group superiority trial that seeks to enroll emergency department patients with inclusion criteria that are consistent with the original early goal-directed therapy (EGDT) trial (suspected or confirmed infection, two or more systemic inflammatory response syndrome criteria, and refractory hypotension or elevated lactate), is powered to detect a 6–8 % absolute mortality reduction (hospital or 90-day), and uses trained teams to deliver EGDT. Design differences appear to primarily be driven by between-country variation in health care context. The main difference between the trials is the inclusion of a third, alternative resuscitation strategy arm in ProCESS. CONCLUSIONS Harmonization of study design and methods between severe sepsis trials is feasible and may facilitate pooling of data on completion of the trials.

Abstract
The pharmacokinetics of beta-lactam antibiotics in intensive care patients may be profoundly altered due to the dynamic, unpredictable pathophysiological changes that occur in critical illness. For many drugs, significant increases in the volume of distribution and/or variability in drug clearance are common. When “standard” beta-lactam doses are used, such pharmacokinetic changes can result in subtherapeutic plasma concentrations, treatment failure, and the development of antibiotic resistance. Emerging data support the use of beta-lactam therapeutic drug monitoring (TDM) and individualized dosing to ensure the achievement of pharmacodynamic targets associated with rapid bacterial killing and optimal clinical outcomes. The purpose of this work was to describe the pharmacokinetic variability of beta-lactams in the critically ill and to discuss the potential utility of TDM to optimize antibiotic therapy through a structured literature review of all relevant publications between 1946 and October 2011. Only a few studies have reported the utility of TDM as a tool to improve beta-lactam dosing in critically ill patients. Moreover, there is little agreement between studies on the pharmacodynamic targets required to optimize antibiotic therapy. The impact of TDM on important clinical outcomes also remains to be established. Whereas TDM may be theoretically rational, clinical studies to assess utility in the clinical setting are urgently required.

Abstract
BACKGROUND Enteral nutrition (EN) is widely accepted as the preferred method for providing nutrition therapy to critically ill patients. However, optimal energy goals and the best way to achieve those goals are ill defined. OBJECTIVE To determine the type and energy concentration of commonly prescribed EN formulations and whether energy-dense formulations (> 1 kcal/mL) are used. DESIGN Prospective, observational, multicentre, single-day, point-prevalence study. PARTICIPANTS AND SETTING All patients present in 38 Australian and New Zealand intensive care units at 10:00 on 17 November 2010. MAIN OUTCOME MEASURES Demographic data, admission diagnosis and information on EN administration were collected. RESULTS 522 patients were enrolled. Mean age was 58.7 (SD, 17.3) years, 65% were male and 79% were mechanically ventilated. On study day, 220/522 patients received EN (43%; 95% CI, 39%-48%). ICU admission source, Acute Physiology and Chronic Health Evaluation (APACHE) III diagnostic category, APACHE II score and ventilation on study day predicted receipt of EN. Of those receiving EN, 111/220 (51%; 95% CI, 44%-57%) received a 1 kcal/mL formulation and the remainder received an energy-dense formulation - 2 kcal/mL, 39/220 (18%; 95% CI, 13%-23%); and 1.5 kcal/mL, 32/220 (15%; 95% CI, 10%-20%). There were no significant predictors for receipt of energy-dense versus 1 kcal/mL EN. CONCLUSIONS 1 kcal/mL and energy-dense formulations are administered with about equal frequency in Australian and New Zealand ICUs. This finding supports future research into the evaluation of optimal nutritional delivery amounts using EN formulations with differing energy concentrations.

Abstract
The prevalence of invasive fungal infections (IFIs) caused by Candida spp. is increasing in critically ill patients. Recent development of new antifungal agents has significantly contributed to the successful treatment of IFIs. However, the pharmacokinetics of antifungal agents can be altered in a number of disease states, including critical illness. Therefore, doses established in healthy volunteers and other patient groups may not be appropriate for the critically ill. Moreover, inadequate dosing may contribute to treatment failure and the emergence of resistance. This systematic review provides a critical analysis of the pharmacokinetics of antifungal agents in the critically ill and their relevance to dosing requirements in clinical practice. Based on the limited data available, dosing of some antifungal agents may have to be adjusted in critically ill patients with conserved renal function as well as in those requiring renal replacement therapy. Further research to confirm the appropriateness of current dosing strategies to attain the appropriate pharmacodynamic targets is recommended.

Abstract
INTRODUCTION Invasive candidiasis has emerged over the last few decades as an increasingly important nosocomial problem for the critically ill, affecting around 2% of intensive care unit patients. Although poor outcomes associated with invasive candidiasis among critically ill patients may relate to severe underlying disease processes and delayed institution of antifungal therapy, inadequate dosing of antifungal agents may also contribute. AREAS COVERED This drug evaluation provides a critical appraisal of the published literature pertaining to the pharmacokinetics of fluconazole in critically ill, obese or severely burned patients, including those receiving acute renal replacement therapy. The pharmacodynamics of fluconazole is also covered, as well as the likely clinical implications for optimal dosing and the toxicity of fluconazole. Last, variations in fluconazole susceptibility patterns of Candida spp. are also discussed. EXPERT OPINION Recently, there has been an increased but geographically variable prevalence of non-albicans Candida spp., causing invasive candidiasis and an overall trend towards reduced fluconazole susceptibility. The pathophysiological changes of critical illness, coupled with a lack of dose finding studies, support the use of local susceptibility patterns to guide fluconazole dosing until such time as pharmacokinetic-pharmacodynamic information to guide optimal fluconazole dosing strategies and pharmacodynamic targets becomes available.

Abstract
OBJECTIVE A study was undertaken to characterise how doctors in emergency medicine (EM), acute medicine (AM) and critical care (ICU) in the UK, USA and Australia and New Zealand (ANZ) approach the initial resuscitative care of patients with severe sepsis. METHODS In 2007, members on the mailing lists of UK, US and ANZ EM, ICU and AM specialist organisations were invited to answer an anonymous scenario-based online survey. Respondents described their management of a patient with pneumonia and signs of sepsis. Multiple-choice questions were based on the Surviving Sepsis Campaign (SSC) 6-hour resuscitation bundle guidelines while avoiding the specific terms "sepsis" and "SSC guidelines". RESULTS The response rate was 21% (2461/11 795). Only two respondents (0.1%) complied with all SSC resuscitation recommendations. Inter-specialty and inter-country variations included differences in reporting initial lactate measurement (ranging from 30% in US-EM to 79% in UK-EM), fluid resuscitation targeting a central venous pressure of 8-12 mm Hg (from 15% in ANZ-ICU to 60% in UK-EM), blood transfusion for a central venous oxygen saturation <70% and haematocrit <30% (from 15% in ANZ-ICU to 70% in US-EM and UK-EM) and insertion of invasive monitoring (intra-arterial catheter: 89% in UK-ICU vs 20% in US-EM; central venous catheter: 83% in UK-ICU vs 44% in US-EM). 81% of respondents identified at least one reason why they did not implement all the recommendations; the reasons varied by region and specialty. CONCLUSIONS Reported management of early sepsis varies between specialities and countries, and the responses do not follow SSC guidelines. Concerns relate to knowledge, attitudes and resources.
