The essay investigates Romantic tendencies in Schiller's inaugural drama, Die Räuber [The Robbers]. The play's overt discourse of dualism and exchange rests on a more viscous foundation of existential muck. Franz von Moor's "morastige Zirkel der menschlichen Bestimmung" [muckish cycle of human determination] is a cyclical solvent that engulfs the play's dualisms and dissolves opposition and exchange. Forms rise from the muck, taking on borders (dimensions, limits) and they descend back into the muck, becoming once more borderless. This may be the other side of an all-encompassing Freude [Joy], both originary and terminal, yet as "alle Menschen werden Brüder" [all people become brothers], we are reminded of what it means to be brothers in the Moor clan. As a belated product of the proto-Romanticism of the Sturm und Drang, Schiller's 1781 play is a specimen of retro-proto-Romanticism.

Inadequate ventilation of intubated patients during transport from the operating theatre to the intensive care unit with attendant hypercarbia may adversely affect haemodynamics. In a retrospective observational study, we assessed the incidence of inadequate ventilation during transport from the operating theatre to the intensive care unit in 99 consecutive cardiac surgery patients admitted to our university tertiary hospital. Demographic, clinical, arterial blood gas and haemodynamic measurements were made on arrival in the intensive care unit after cardiac surgery. The relationships between arterial carbon dioxide tension (P(a)CO2), mean pulmonary artery pressure (MPAP) and other relevant haemodynamic variables were explored. Overall, hypocarbia (P(a)CO2 < 35 mmHg) occurred in 18.2% of patients, while 28.3% of patients had hypercarbia (P(a)CO2 > 45 mmHg). Pulmonary hypertension was common, with nearly half of the cohort having MPAP > or = 25 mmHg and 17.2% > or = 30 mmHg. However there was no association between P(a)CO2 and MPAP (R2 = 0.0076, P = 0.39). Contrary to expectation, neither hypercarbia nor high MPAP were associated with measured adverse outcomes, although this may have been because we studied an insufficient number of patients with extreme values. Associations of higher MPAP, which would be expected to compromise cardiovascular status, included acidaemia, hypoxia and the requirement for noradrenaline. These factors define a group of high-risk patients who should receive particular attention and who should be the focus of future studies. [ABSTRACT FROM AUTHOR]

The objective of this study was to analyse and report on the distribution and attributes of intensive care services in Australia and New Zealand for the 2005/2006 financial year A survey was mailed to 155 Australian and 26 New Zealand intensive care units (ICU) listed on the database of the Australian and New Zealand Intensive Care Society. A descriptive analytical approach was used. Of the 181 ICUs, 177 provided data. In Australia there were 100 public sector and 51 private sector ICUs and in New Zealand, 24 public sector and two private sector ICUs. These units contain 1485 available beds in the public sector and 538 available beds in the private sector Calculations to determine beds per 100,000 population, medical specialists per 1000 patient days and registered nurses per 1000 patient days showed wide variation. International comparisons are limited by lack of data; however it does appear that intensive care patients in Australia and New Zealand have very good outcomes. [ABSTRACT FROM AUTHOR]

Objectives In this overview, we describe theObservational Medical Outcomes Partnership Common Data Model (OMOP-CDM), the established governance processes employed in EMR data repositories, and demonstrate how OMOP transformed data provides a lever for more efficient and secure access to electronic medical record (EMR) data by health service providers and researchers. Methods Through pseudonymisation and common data quality assessments, the OMOP-CDM provides a robust framework for converting complex EMR data into a standardised format. This allows for the creation of shared end-to-end analysis packages without the need for direct data exchange, thereby enhancing data security and privacy. By securely sharing de-identified and aggregated data and conducting analyses across multiple OMOP-converted databases, patient-level data is securely firewalled within its respective local site. Results By simplifying data management processes and governance, and through the promotion of interoperability, the OMOP-CDM supports a wide range of clinical, epidemiological, and translational research projects, as well as health service operational reporting. Discussion Adoption of the OMOP-CDM internationally and locally enables conversion of vast amounts of complex, and heterogeneous EMR data into a standardised structured data model, simplifies governance processes, and facilitates rapid repeatable cross-institution analysis through shared end-to-end analysis packages, without the sharing of data. Conclusion The adoption of the OMOP-CDM has the potential to transform health data analytics by providing a common platform for analysing EMR data across diverse healthcare settings., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

The Learning Health Systems (LHS) framework demonstrates the potential for iterative interrogation of health data in real time and implementation of insights into practice. Yet, the lack of appropriately skilled workforce results in an inability to leverage existing data to design innovative solutions. We developed a tailored professional development program to foster a skilled workforce. The short course is wholly online, for interdisciplinary professionals working in the digital health arena. To transform healthcare systems, the workforce needs an understanding of LHS principles, data driven approaches, and the need for diversly skilled learning communities that can tackle these complex problems together.

In 2023, the Australian and New Zealand Intensive Care Society (ANZICS) Registry run by the Centre for Outcomes and Resources Evaluation (CORE) turns 30 years old. It began with the Adult Patient Database, the Australian and New Zealand Paediatric Intensive Care Registry, and the Critical Care Resources Registry, and it now includes Central Line Associated Bloodstream Infections Registry, the Extra-Corporeal Membrane Oxygenation Database, and the Critical Health Resources Information System. The ANZICS Registry provides comparative case-mix reports, risk-adjusted clinical outcomes, process measures, and quality of care indicators to over 200 intensive care units describing more than 200 000 adult and paediatric admissions annually. The ANZICS CORE outlier management program has been a major contributor to the improved patient outcomes and provided significant cost savings to the healthcare sector. Over 200 peer-reviewed papers have been published using ANZICS Registry data. The ANZICS Registry was a vital source of information during the COVID-19 pandemic. Upcoming developments include reporting of long-term survival and patient-reported outcome and experience measures., (© 2023 The Authors.

Background: Successful implementation of rapid response teams (RRTs) requires robust data collection and reporting processes. However, there is variation in data collection practice in RRT activity between hospitals, leading to difficulties in quality review, collaboration and research. Although a standardised RRT data collection model would be a key step in addressing this, there is uncertainty regarding existing RRT data collection practice across Victoria., Objectives: This study was endorsed by Safer Care Victoria (SCV) to evaluate existing RRT data collection practice across Victoria., Methodology: Between 2016 and 2017, hospitals in Victoria were surveyed on data collection practice for RRT activity. Data collected included the fields populated and the mode of data collection. Qualitative content analysis, utilising a blend of pre-existing frameworks and ground-up data-driven approaches for derivation of a coding frame, was used to identify common categories. Validation of the analysis and results was performed by consultation with stakeholder groups., Results: Twenty five hospitals across 18 health networks contributed data, with a mix of tertiary (9/25), metropolitan (11/25) and rural (5/25) hospitals. Seven hospitals collected data electronically, the remainder using paper with abstraction to electronic spreadsheets. None of the hospitals linked with existing hospital data systems to reduce manual data entry requirements. Dataset size varied from 16 to 97 variables but demonstrated content consistency and could be mapped onto seven key categories (comprising antecedent, afferent, event, post-event, audit, context and patient data). Within each category, there was substantial variation in terminology and variable values, but consistency in the collection of a certain subset of variables., Conclusion: Despite broad variation in data collection practice, existing datasets can be readily mapped into seven key categories, with the consistent collection of a subset of variables within each category. These variables could inform the development of a minimum dataset within a standardised RRT reporting framework and accommodate data submission from hospitals of differing resource bases., (Copyright © 2021 Australian College of Critical Care Nurses Ltd.

Background: News of the impact of COVID-19 around the world delivered a brief opportunity for Australian health services to plan new ways of delivering care to large numbers of people while maintaining staff safety through greater physical separation. The rapid pivot to telemedicine and virtual care provided immediate and longer term benefits; however, such rapid-cycle development also created risks., Objective: The aim of this study was to understand the sociotechnical aspects of the rapid-cycle development of seven different COVID-19 virtual care tools, and to identify enablers, barriers, and risks at three health services in Victoria, Australia., Methods: A qualitative, embedded, multiple case study design was adopted. Researchers from three health services collaborated with university researchers who were independent from those health services to gather and analyze structured interview data from key people involved in either clinical or technical aspects of designing and deploying seven different virtual care tools., Results: The overall objectives of each health service reflected the international requirements for managing large numbers of patients safely but remotely and for protecting staff. However, the governance, digital maturity, and specific use cases at each institution shaped the methodology and specific outcomes required. Dependence on key individuals and their domain knowledge within an existing governance framework generally enabled rapid deployment, but sometimes posed barriers. Existing relationships with technical service developers enabled strong solutions, which in some cases were highly scalable. Conventional project methodologies such as steering committees, scope, budget control, tight functional specification, consumer engagement and codesign, universal accessibility, and postimplementation evaluation were ignored almost universally in this environment., Conclusions: These three health services took a variety of approaches to the rapid-cycle development of virtual care tools to meet their urgent needs for triaging and remote monitoring during the first year of the COVID-19 pandemic. Their experiences provided insights into many social and technical barriers and enablers to the development of virtual care tools. If these are addressed proactively, they will improve clinical governance and technical management of future virtual care. Some changes can be made within individual health services, while others entail health system policy reforms. Enhancing the environment for virtual care tool design and implementation now will yield returns not only during future health emergencies but also in many more routine care settings., (©Kathleen Gray, Wendy Chapman, Urooj R Khan, Ann Borda, Marc Budge, Martin Dutch, Graeme K Hart, Cecily Gilbert, Tafheem Ahmad Wani.

Background: Abnormalities in serum potassium are a well known complication of chronic kidney disease (CKD), but little is known about their impact on inpatient outcomes., Aims: To better understand the role of dyskalaemia in hospital in-patients, we assessed the epidemiology of potassium disorders among CKD patients, and the association between admission potassium and inpatient mortality or intensive care unit (ICU) requirement., Methods: This retrospective hospital-based cohort study (n = 11 156) included patients with an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m 2 admitted to Austin Health between 2014 and 2018 and who had an admission potassium value. Dialysis patients or those with a renal transplant were excluded. Multivariate logistic analysis was conducted to identify factors associated with hyperkalaemia (≥5.5 mmol/L) and hypokalaemia (<3.5 mmol/L). Odds ratios for inpatient mortality and ICU admission between potassium categories were obtained by multivariate regression with adjustments for demographics, renal function and comorbidities., Results: Hyperkalaemia and hypokalaemia were present in 6.86% and 2.94% of hospital admissions respectively. In multivariate regression male sex, lower eGFR, diabetes and cardiac failure were associated with higher odds of hyperkalaemia. Thiazide diuretics, loop diuretics, infectious disease and endocrine pathology were associated with higher odds of hypokalaemia. A U-shaped association was noted between potassium and inpatient mortality. Potassium <4.0 mmol/L and ≥5.0 mmol/L was associated with increased mortality. Only patients with potassium ≥5.5 mmol/L had increased ICU admission risk., Conclusion: Derangements in potassium frequently occur in CKD inpatients and are independently associated with higher mortality and ICU requirement. Further studies are required to determine whether interventions to maintain normokalaemia improve outcomes in this population., (© 2020 Royal Australasian College of Physicians.)

Background: There is limited knowledge of whether hypercoagulability is present after subarachnoid hemorrhage (SAH) or about its timing of onset, duration, and severity. To conduct a pilot new-generation thromboelastography (TEG) technology (TEG6s)-based and conventional coagulation test-supported longitudinal assessment of coagulation in patients with SAH., Methods: We prospectively enrolled patients with nontraumatic SAH on admission from May 2015 to May 2016. We performed TEG6s measurements and conventional coagulation tests on days 1, 2, 3, 5, 7, 10, and 14 and compared them with TEG6s parameters in healthy volunteers., Results: We studied 14 patients and 72 TEG6s measurements. Of these patients, 10 (71.4%) were admitted to the intensive care unit. Mean age was 57.5 (±14.5) years, Acute Physiology and Chronic Health Evaluation III score 58.2 (±26.6), length of hospital stay was 23 (±11.7) days, and mortality was 14.3%. At baseline, conventional coagulation tests were within normal range. However, TEG6s parameters already showed increased coagulability. Thereafter, alpha angle, reaction time, functional fibrinogen level, and maximum amplitude rapidly and significantly increased (P < 0.01) compared with healthy controls. Ten (71.4%) patients demonstrated a >20% increase in coagulability based on TEG6s parameters from their baseline. Moreover, TEG6s hypercoagulability peaked at day 10 and only showed an initial partial decline towards normal by day 14. Similarly, platelet counts and fibrinogen levels increased over this period (P < 0.01) CONCLUSIONS: Using TEG6s technology, we found significant and progressive hypercoagulability in 70% of patients, with an early dominant contribution from hyperfibrinogenemia and increased fibrin formation and partial contribution from thrombocytosis, beginning on the first day, increasing to peak values by day 10, and then partly declining toward normal by day 14., (Crown Copyright © 2019.

Objective: To assess the association between glycaemic status prior to the first hospital presentation with developing adverse renal outcomes overtime in patients with multiple hospital re-admissions., Design: A prospective observational cohort study., Participants: All inpatients aged ≥54 years admitted between 2013 and 16 to a tertiary hospital., Main Outcomes: We prospectively measured HbA1c levels in all inpatients aged ≥54 years admitted between 2013 and 16. Diabetes was defined as prior documented diagnosis of diabetes and/or HbA1c ≥6.5% (47·5 mmol/L). Included patients had ≥ two admissions (at least 90 days apart), baseline estimated glomerular filtration rate (eGFR) >30 ml/min/1·73m 2 and no history of renal replacement therapy. We assessed several renal outcomes: (a) 50% decline in eGFR; (b) rapid decline in renal function (eGFR decline >5 mL/min/1·73m 2 /year) and (c) final eGFR<30 ml/min/1·73m 2 ., Results: Of 4126 inpatients with a median follow-up of 465 days (254, 740), 26% had diabetes. The presence of diabetes was associated with higher odds of (a) 50% decline in eGFR (OR = 1·42;95% CI:1·18-1·70;p < 0·001); (b) rapid decline in renal function (OR = 1·40;95%CI:1·20-1·63;p < 0·001), and (c) reaching eGFR<30 ml/min/1.73m 2 (OR = 1·25;95%CI:1·03-1·53;p < 0·05). Every 1% (11 mmol/L) increase in baseline HbA1c was associated with significantly greater odds of (a) >50% decline in eGFR (OR = 1·07;95% CI:1·01-1·4;p < 0·05) and (b) rapid decline in renal function (OR = 1·11;95% CI:1·05-1·18;p < 0·001)., Conclusions: In patients with ≥two admissions, the presence of diabetes and higher HbA1c levels were strongly and independently associated with adverse renal outcomes at follow up. Such patients are at high risk of relatively rapid deterioration in renal function and a logical target for structured preventive interventions., (Copyright © 2019 Elsevier Inc.

Objective: Thromboelastography (TEG) may provide rapid and clinically important coagulation information in acutely ill patients with chronic liver disease (CLD). Our objective was to describe the relationship between TEG and conventional coagulation tests (CCTs), which has not been previously explored in this population., Methods: In acutely ill patients with severe CLD (Child-Pugh score > 9, category C), we conducted a prospective observational study investigating coagulation assessment as measured by both CCTs and TEG. We used quantile regression to explore 30 associations between TEG parameters and corresponding CCTs. We compared TEG and CCT measures of coagulation initiation, clot formation, clot strength, and fibrinolysis., Results: We studied 34 patients on a total of 109 occasions. We observed inconsistent associations between TEG and CCT measures of coagulation initiation: TEG (citrated kaolin [CK] assay) standard reaction time and international normalized ratio: R 2 = 0.117 ( P = .044). Conversely, there were strong and consistent associations between tests of clot formation: TEG (CK) kinetics time and fibrinogen: R 2 = 0.202 ( P < .0001) and TEG (CK) α angle and fibrinogen 0.263 ( P < .0001). We also observed strong associations between tests of clot strength, specifically TEG MA and conventional fibrinogen levels, across all TEG assays: MA (CK) and fibrinogen: R 2 = 0.485 ( P < .0001). There were no associations between TEG and D-dimer levels., Conclusions: In acutely ill patients with CLD, there are strong and consistent associations between TEG measures of clot formation and clot strength and conventional fibrinogen levels. There are weak and/or inconsistent associations between TEG and all other conventional measures of coagulation.

Background: 3-factor prothrombin complex concentrate (3F-PCC) may provide a valuable treatment option for coagulopathy in cardiac surgery patients. However, it may expose patients to increased risk of thromboembolic events. Accordingly, we compared the incidence of thromboembolic events between patients exposed to 3F-PCC and those receiving conventional therapy., Methods: Demographic, operative and postoperative data was obtained in a cohort of consecutive patients exposed to 3F-PCC and a contemporaneous control population. Propensity-score matching was performed for risk adjustment. Unadjusted and adjusted patient demographics and incidence of thromboembolism were compared., Results: Patients receiving 3F-PCC (PCC) were younger (mean age PCC: 64±14.2 vs. No PCC: 67.6±11.6, p=0.022), and less likely to have diabetes or previous myocardial infarction. PCC patients experienced more prolonged aortic cross clamp times (mean time in minutes PCC: 119.9±58.8 vs. No PCC: 92.3±54), more complex cardiac surgeries and were more likely to have received more fresh frozen plasma (FFP), cryoprecipitate and red blood cells. Despite this, both unadjusted and adjusted 30-day mortality and readmission rates were similar between groups. There were 9 (9.2%) and 34 (6.8%) (p=0.40) thromboembolic events in the unadjusted PCC and control groups respectively. Adjusted risk for thromboembolic event rates was also comparable (Odds ratio: 1.512, 95% Confidence Interval 0.401-5.7, p=0.541)., Conclusions: 3-factor prothrombin complex concentrate was administered to patients at greater risk of complications including bleeding. Our initial experience suggests that the use of PCC does not appear to increase thromboembolic risks compared to conventional treatment., (Copyright © 2018 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Aims: We aimed to confirm the hypothesis that dysglycaemia including in the pre-diabetes range affects a majority of patients admitted with acute coronary syndrome (ACS) and is associated with worse outcomes., Methods: In this prospective observational cohort study, consecutive inpatients aged ≥ 54 years with ACS were uniformly tested and categorised into diabetes (prior diagnosis/ HbA1c ≥ 6.5%, ≥48 mmol/mol), pre-diabetes (HbA1c 5.7-6.4%, 39-47 mmol/mol) and no diabetes (HbA1c ≤ 5.6%, ≤38 mmol/mol) groups., Results: Over two years, 847 consecutive inpatients presented with ACS. 313 (37%) inpatients had diabetes, 312 (37%) had pre-diabetes and 222 (25%) had no diabetes. Diabetes, compared with no diabetes, was associated with higher odds of acute pulmonary oedema (APO, odds ratio, OR 2.60, p < 0.01), longer length of stay (LOS, incidence rate ratio, IRR 1.18, p = 0.02) and, 12-month ACS recurrence (OR 1.86, p = 0.046) after adjustment, while no significant associations were identified for pre-diabetes. Analysed as a continuous variable, every 1% (11 mmol/mol) increase in HbA1c was associated with increased odds of APO (OR 1.28, P = 0.002) and a longer LOS (IRR 1.05, P = 0.03)., Conclusions: The high prevalence of dysglycaemia and association with poorer clinical outcomes justifies routine HbA1c testing to identify individuals who may benefit from cardioprotective anti-hyperglycaemic agents and, lifestyle modification to prevent progression of pre-diabetes., (Copyright © 2019 Elsevier B.V.

Aim: Common blood tests can help identify patients at risk of death, unplanned intensive care unit (ICU) admission, or rapid response team (RRT) call. We aimed to test whether early ICU-team review triggered by such laboratory tests (lab alert) is feasible, safe, and can alter physiological variables, clinical management, and clinical outcomes., Methods: In prospective pilot randomized controlled trial in surgical wards of a tertiary hospital, we studied patients admitted for >24 h. We applied a previously validated risk assessment tool to each set of common laboratory tests to identify patients at risk and generate a "lab-alert". We randomly allocated such lab-alert patients to receive early ICU-team review (intervention) or usual care (control)., Results: We studied 205 patients (males 54.1%; average age 79 years; 103 randomized to intervention and 102 to usual care). Intervention patients were more likely to trigger RRT activation during their first lab-alert (10.7 vs. 2.0%; P < 0.001) but less likely to receive an allied health referral (18.0% vs. 24.5%; p = 0.007). They were less likely to trigger RRT activation in the 24-h before subsequent alerts (18.4 vs. 22.4%; p = 0.008) and less likely to generate further alerts (204 vs. 320; p < 0.001), but more likely to receive a not for resuscitation or endotracheal intubation status in the 24-h before subsequent alerts (26.6 vs. 17.3%; p = 0.05). Mortality at 24 h was 1.9% for the intervention group vs. 2.9% in the control group (p = 0.63). Finally, overall mortality was 19.4% for intervention patients vs. 23.5% for control patients (p = 0.50)., Conclusion: Among surgical patients, lab alerts identify patients with a high mortality. Lab alert-triggered interventions are associated with more first alert-associated RRT activations; more changes in resuscitation status toward a more conservative approach; fewer subsequent alert-associated RRT activations; fewer subsequent alerts, and decreased allied health interventions (ANZCTRN12615000146594)., (Copyright © 2018 Elsevier B.V.

Aims: Diabetes is a major risk factor for stroke. We aimed to investigate the prevalence of diabetes and pre-diabetes within a stroke cohort and examine the association of glycaemia status with mortality and morbidity., Methods: Inpatients aged ≥54 who presented with a diagnosis of stroke had a routine HbA1c measurement as part of the Austin Health Diabetes Discovery Initiative. Additional data were attained from hospital databases and Australian Stroke Clinical Registry. Outcomes included diabetes and pre-diabetes prevalence, length of stay, 6-month and in-hospital mortality, 28-day readmission rates, and 3-month modified Rankin scale score., Results: Between July 2013 and December 2015, 610 patients were studied. Of these, 31% had diabetes while 40% had pre-diabetes. Using multivariable regression analyses, the presence of diabetes was associated with higher odds of 6-month mortality (OR = 1.90, p = 0.022) and higher expected length of stay (IRR = 1.29, p = 0.004). Similarly, a higher HbA1c was associated with higher odds of 6-month mortality (OR = 1.27, p = 0.005) and higher expected length of stay (IRR = 1.08, p = 0.010)., Conclusions: 71% of this cohort had diabetes or pre-diabetes. Presence of diabetes and higher HbA1c were associated with higher 6-month mortality and length of stay. Further research is necessary to determine if improved glycaemic control may improve stroke outcomes., (Copyright © 2018 Elsevier Inc. All rights reserved.)
