The Acute Dialysis Quality Initiative (ADQI) Group published a consensus definition (the RIFLE criteria) for acute renal failure. We sought to assess the ability of criteria predict mortality in hospital patients.Retrospective single-center study.University-affiliated hospital.All patients admitted study between January 2000 and December 2002. Patients were excluded if they younger than 15 yrs old, on chronic dialysis, or had kidney transplant their length stay was <24 hrs.None.We included...
It is unclear whether vitamin C, hydrocortisone, and thiamine are more effective than hydrocortisone alone in expediting resolution of septic shock. To determine the combination thiamine, compared with alone, improves duration time alive free vasopressor administration patients Multicenter, open-label, randomized clinical trial conducted 10 intensive care units Australia, New Zealand, Brazil that recruited 216 fulfilling Sepsis-3 definition The first patient was enrolled on May 8, 2018, last...
Importance Whether selective decontamination of the digestive tract (SDD) reduces mortality in critically ill patients remains uncertain. Objective To determine whether SDD in-hospital adults. Design, Setting, and Participants A cluster, crossover, randomized clinical trial that recruited 5982 mechanically ventilated adults from 19 intensive care units (ICUs) Australia between April 2018 May 2021 (final follow-up, August 2021). contemporaneous ecological assessment 8599 participating ICUs...
Abstract Introduction Agitated delirium is common in patients undergoing mechanical ventilation, and often treated with haloperidol despite concerns about safety efficacy. Use of conventional sedatives to control agitation can preclude extubation. Dexmedetomidine, a novel sedative anxiolytic agent, may have particular utility these patients. We sought compare the efficacy dexmedetomidine facilitating Methods conducted randomised, open-label, parallel-groups pilot trial medical surgical...
It is unknown whether the reported short-term reduction in cardiac arrests associated with introduction of medical emergency team (MET) system can be sustained. We conducted a prospective, controlled before-and-after examination effect MET on long-term incidence arrests. included consecutive patients admitted during three study periods: before MET; education phase preceding implementation and period four years from system. Cardiac were identified log book arrest calls cross-referenced case...
BackgroundThe Duke Activity Status Index (DASI) questionnaire might help incorporate self-reported functional capacity into preoperative risk assessment. Nonetheless, prognostically important thresholds in DASI scores remain unclear. We conducted a nested cohort analysis of the Measurement Exercise Tolerance before Surgery (METS) study to characterise association with postoperative death or complications.MethodsThe included 1546 participants (≥40 yr age) at an elevated cardiac who had...
Patients and caregivers can experience a range of physical, psychologic, cognitive problems following critical care discharge. The use peer support has been proposed as an innovative mechanism.We sought to identify technical, safety, procedural aspects existing operational models support, among the Society Critical Care Medicine Thrive Peer Support Collaborative. We also categorize key distinctions between these elucidate barriers facilitators implementation.Seventeen sites from United...
We extend previous studies on the impact of masks COVID-19 outcomes by investigating an unprecedented breadth and depth health outcomes, geographical resolutions, types mask mandates, early versus later waves controlling for other government interventions, mobility testing rate weather. show that mandates are associated with a statistically significant decrease in new cases (-3.55 per 100K), deaths (-0.13 proportion hospital admissions (-2.38 percentage points) up to 40 days after...
Late Pleistocene Clovis fluted points and stone flake tools have been found in association with bison at several archaeological sites western North America. To gain insight into how these may functioned butchery, as well to assess the assumptions or interpretations of implements by archaeologists, we conducted a bison-processing experiment. We examined relative efficacy butchering process hafted versus handheld flakes different point forms; types tool breakage that might occur during...
To test the ability of a novel super high-flux (SHF) membrane with larger pore size to clear myoglobin from serum.The intensive care unit university teaching hospital.A patient serotonin syndrome complicated by severe rhabodomyolysis and oliguric acute renal failure.Initially continuous veno-venous hemofiltration was performed at 2 l/hour ultrafiltration (UF) standard polysulphone 1.4 m2 (cutoff point, 20 kDa), followed SHF 100 kDa) UF, then 3 UF 4 in an attempt myoglobin.The concentration...
Much waste arises from operating rooms (ORs). We estimated the practical and financial feasibility of an OR recycling program, weighing all 6 ORs in Melbourne, Australia. Over 1 week, 237 operations produced 1265 kg total: general 570 (45%), infectious 410 (32%), recyclables 285 (23%). The achieved had no contamination. recycling/potential rate was kg/517 (55%). average disposal costs were similar for recycling. rates 20%–25% total achievable without compromising infection control or constraints.
Cardiopulmonary exercise testing (CPET) is an stress test with concomitant expired gas analysis that provides objective, non-invasive measure of functional capacity under stress. CPET-derived variables predict postoperative morbidity and mortality after major abdominal thoracic surgery. Two previous surveys have reported increasing utilisation CPET preoperatively in England. We aimed to evaluate current practice the UK, identify who performs CPET, how it performed, data generated are used...
Rationale: Blood glucose concentrations affect outcomes in critically ill patients, but the optimal target blood range those with type 2 diabetes is unknown. Objectives: To evaluate effects of a "liberal" approach to targeted during ICU admission. Methods: This mutlicenter, parallel-group, open-label randomized clinical trial included 419 adult patients expected be on at least three consecutive days. In intervention group intravenous insulin was commenced >252 mg/dl and titrated 180-252...
Abstract Introduction Hospital medical emergency teams (METs) have been implemented to reduce cardiac arrests and hospital mortality. The timing system factors associated with their activation are poorly understood. We sought determine the circadian pattern of MET relate it nursing activities. Method conducted a retrospective observational study time for 2568 incidents attendance. Each attendance was allocated one 48 half-hour intervals over 24-hour daily cycle. Activation related Results...
Patients in the intensive care unit often suffer from lack of sleep at night. We hypothesised that nocturnal melatonin may increase observed tracheostomised patients.Double-blind, randomised, placebo-controlled pilot study.ICU a tertiary hospital.Thirty-two ICU patients with tracheostomy who were not receiving continuous sedation.We administered either oral (3mg) or placebo 20:00. collected pre- and post-dosage blood samples on Days 1 3 to confirm drug delivery. Primary outcome measure was...
<h3>Background</h3> The presence of an association between early subtherapeutic activated partial thromboplastin times (aPTTs) and recurrent venous thromboembolism (VTE) remains controversial. <h3>Objective</h3> To determine the relation aPTTs VTE in patients who were treated with intravenous (IV) unfractionated heparin (UFH). <h3>Patients Methods</h3> We studied 961 acute received IV UFH 3 randomized trials that compared use (loading dose: 5000 U IV; initial infusion, 1250-1280 U/h)...
Abstract Background: Medical Emergency Teams (MET) have been developed to identify, review and manage acutely unwell ward patients. Previous studies suggested that there may be obstacles the utilization activation of MET. Aims: To determine effect a detailed education programme on rate MET system 3.5 years after its introduction in University teaching hospital. Methods: Prospective interventional study involving education, feedback decision support for nursing medical staff given before,...
