Infectious and sepsis presentations to, and hospital admissions from emergency departments in Victoria, Australia. Emerg Med Australas 2024; 36:450-458. [PMID: 38413376 DOI: 10.1111/1742-6723.14384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 01/26/2024] [Accepted: 02/08/2024] [Indexed: 02/29/2024]
Abstract
OBJECTIVE To investigate the frequency and outcomes of adult infectious and sepsis presentations to, and hospital admissions from, Emergency Departments (EDs) in Victoria, Australia. METHODS Retrospective cohort study using the Victorian Emergency Minimum Dataset and Victorian Admitted Episodes Dataset. We included adults (age ≥ 18 years) presenting to an ED, or admitted to hospital from ED in Victoria between July 2017 and June 2018. One-year mortality was analysed until June 2019 using the Victorian Death Index, and ICD-10 coding was used to identify cases. RESULTS Among 1.28 million ED presentations over 1 year, 12.00% and 0.45% were coded with infectious and sepsis diagnoses, respectively. Despite having lower triage categories, patients with infections were more likely to be admitted to hospital (50.4% vs 44.9%), but not directly to ICU (0.8%). Patients coded with sepsis were assigned higher triage categories and required hospital admission much more frequently (96.4% vs 44.9%), including to ICU (15.9% vs 0.8%). Patients presenting with infections and sepsis had increased risk of 1-year mortality (adjusted hazard ratio 1.44 and 4.13, respectively). Of the 648 280 hospital admissions from the ED, infection and sepsis were coded in 23.69% and 2.66%, respectively, and the adjusted odds ratio for 1-year mortality were 1.64 and 4.79, respectively. CONCLUSIONS Infections and sepsis are common causes of presentation to, and admission from the ED in Victoria. Such patients experience higher mortality than non-infectious patients, even after adjusting for age. There is a need to identify modifiable factors contributing to these outcomes.

Haemodynamic changes during prone versus supine position in patients with COVID-19 acute respiratory distress syndrome. Aust Crit Care 2024; 37:391-399. [PMID: 37160405 PMCID: PMC10063572 DOI: 10.1016/j.aucc.2023.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 03/10/2023] [Accepted: 03/25/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Prone positioning improves oxygenation in patients with acute respiratory distress syndrome (ARDS) secondary to COVID-19. However, its haemodynamic effects are poorly understood. OBJECTIVES The objective of this study was to investigate the acute haemodynamic changes associated with prone position in mechanically ventilated patients with COVID-19 ARDS. The primary objective was to describe changes in cardiac index with prone position. The secondary objectives were to describe changes in mean arterial pressure, FiO2, PaO2/FiO2 ratio, and oxygen delivery (DO2) with prone position. METHODS We performed this cohort-embedded study in an Australian intensive care unit, between September and November 2021. We included adult patients with severe COVID-19 ARDS, requiring mechanical ventilation and prone positioning for respiratory failure. We placed patients in the prone position for 16 h per session. Using pulse contour technology, we collected haemodynamic data every 5 min for 2 h in the supine position and for 2 h in the prone position consecutively. RESULTS We studied 18 patients. Cardiac index, stroke volume index, and mean arterial pressure increased significantly in the prone position compared to supine position. The mean cardiac index was higher in the prone group than in the supine group by 0.44 L/min/m2 (95% confidence interval, 0.24 to 0.63) (P < 0.001). FiO2 requirement decreased significantly in the prone position (P < 0.001), with a significant increase in PaO2/FiO2 ratio (P < 0.001). DO2 also increased significantly in the prone position, from a median DO2 of 597 mls O2/min (interquartile range, 504 to 931) in the supine position to 743 mls O2/min (interquartile range, 604 to 1075) in the prone position (P < 0.001). CONCLUSION Prone position increased the cardiac index, mean arterial pressure, and DO2 in invasively ventilated patients with COVID-19 ARDS. These changes may contribute to improved tissue oxygenation and improved outcomes observed in trials of prone positioning.

Improving the pre-medical emergency team: the case for a behavioural theoretical lens. AUST HEALTH REV 2024:AH24041.

Abstract
There is mounting evidence that the pre-medical emergency team (pre-MET) of rapid response systems is underutilised in clinical practice due to suboptimal structures and processes and resource constraints. In this perspective article, we argue for examining the pre-MET through a 'Behaviour Change Wheel' lens to improve the pre-MET and maximise the associated patient safety benefits. Using pre-MET communication practices as an example, we illustrate the value of the COM-B model, where clinicians' 'capability', 'opportunity', and 'motivation' drive 'behaviour'. Optimising clinicians' behaviours and establishing failsafe rapid response systems is a complex undertaking; however, examining clinicians' behaviours through the COM-B model enables reframing barriers and facilitators to develop multifaceted and coordinated solutions that are behaviourally and theoretically based. The COM-B model is recommended to clinical governance leaders and health services researchers to explore the underlying causes of behaviour and successfully enact change in the design, implementation, and use of the pre-MET to improve patient safety.

Dose equivalence for metaraminol and noradrenaline - A retrospective analysis. J Crit Care 2024; 80:154430. [PMID: 38245376 DOI: 10.1016/j.jcrc.2023.154430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 09/11/2023] [Accepted: 09/11/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Noradrenaline and metaraminol are commonly used vasopressors in critically ill patients. However, little is known of their dose equivalence. METHODS We conducted a single centre retrospective cohort study of all ICU patients who transitioned from metaraminol to noradrenaline infusions between August 26, 2016 and December 31, 2020. Patients receiving additional vasoactive drug infusion were excluded. Dose equivalence was calculated based on the last hour metaraminol dose (in μg/min) and the first hour noradrenaline dose (in μg/min) with the closest matched mean arterial pressure (MAP). Sensitivity analyses were performed on patients with acute kidney injury (AKI), sepsis and mechanical ventilation. RESULTS We studied 195 patients. The median conversion ratio of metaraminol to noradrenaline was 12.5:1 (IQR 7.5-20.0) for the overall cohort. However, the coefficient of variation was 77% and standard deviation was 11.8. Conversion ratios were unaffected by sepsis or mechanical ventilation but increased (14:1) with AKI. One in five patients had a MAP decrease of >10 mmHg during the transition period from metaraminol to noradrenaline. Post-transition noradrenaline dose (p < 0.001) and AKI (p = 0.045) were independently associated with metaraminol dose. The proportion of variation in noradrenaline dose predicted from metaraminol dose was low (R2 = 0.545). CONCLUSIONS The median dose equivalence for metaraminol and noradrenaline in this study was 12.5:1. However, there was significant variance in dose equivalence, only half the proportion of variation in noradrenaline infusion dose was predicted by metaraminol dose, and conversion-associated hypotension was common.

Stimulated Raman Histology Interpretation by Artificial Intelligence Provides Near-Real-Time Pathologic Feedback for Unprocessed Prostate Biopsies. J Urol 2024; 211:384-391. [PMID: 38100831 DOI: 10.1097/ju.0000000000003811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 11/30/2023] [Indexed: 12/17/2023]
Abstract
PURPOSE Stimulated Raman histology is an innovative technology that generates real-time, high-resolution microscopic images of unprocessed tissue, significantly reducing prostate biopsy interpretation time. This study aims to evaluate the ability for an artificial intelligence convolutional neural network to interpretate prostate biopsy histologic images created with stimulated Raman histology. MATERIALS AND METHODS Unprocessed, unlabeled prostate biopsies were prospectively imaged using a stimulated Raman histology microscope. Following stimulated Raman histology creation, the cores underwent standard pathological processing and interpretation by at least 2 genitourinary pathologists to establish a ground truth assessment. A network, trained on 303 prostate biopsies from 100 participants, was used to measure the accuracy, sensitivity, and specificity of detecting prostate cancer on stimulated Raman histology relative to conventional pathology. The performance of the artificial intelligence was evaluated on an independent 113-biopsy test set. RESULTS Prostate biopsy images obtained through stimulated Raman histology can be generated within a time frame of 2 to 2.75 minutes. The artificial intelligence system achieved a rapid classification of prostate biopsies with cancer, with a potential identification time of approximately 1 minute. The artificial intelligence demonstrated an impressive accuracy of 96.5% in detecting prostate cancer. Moreover, the artificial intelligence exhibited a sensitivity of 96.3% and a specificity of 96.6%. CONCLUSIONS Stimulated Raman histology generates microscopic images capable of accurately identifying prostate cancer in real time, without the need for sectioning or tissue processing. These images can be interpreted by artificial intelligence, providing physicians with near-real-time pathological feedback during the diagnosis or treatment of prostate cancer.

Abstract
RATIONALE Clinical deterioration of patients hospitalized outside the ICU is a source of potentially reversible morbidity and mortality. To address this, some acute care hospitals have implemented systems aimed at detecting and responding to such patients. OBJECTIVES To provide evidence-based recommendations for hospital clinicians and administrators to optimize recognition and response to clinical deterioration in non-ICU patients. PANEL DESIGN The 25-member panel included representatives from medicine, nursing, respiratory therapy, pharmacy, patient/family partners, and clinician-methodologists with expertise in developing evidence-based Clinical Practice Guidelines. METHODS We generated actionable questions using the Population, Intervention, Control, and Outcomes (PICO) format and performed a systematic review of the literature to identify and synthesize the best available evidence. We used the Grading of Recommendations Assessment, Development, and Evaluation Approach to determine certainty in the evidence and to formulate recommendations and good practice statements (GPSs). RESULTS The panel issued 10 statements on recognizing and responding to non-ICU patients with critical illness. Healthcare personnel and institutions should ensure that all vital sign acquisition is timely and accurate (GPS). We make no recommendation on the use of continuous vital sign monitoring among unselected patients. We suggest focused education for bedside clinicians in signs of clinical deterioration, and we also suggest that patient/family/care partners' concerns be included in decisions to obtain additional opinions and help (both conditional recommendations). We recommend hospital-wide deployment of a rapid response team or medical emergency team (RRT/MET) with explicit activation criteria (strong recommendation). We make no recommendation about RRT/MET professional composition or inclusion of palliative care members on the responding team but suggest that the skill set of responders should include eliciting patients' goals of care (conditional recommendation). Finally, quality improvement processes should be part of a rapid response system. CONCLUSIONS The panel provided guidance to inform clinicians and administrators on effective processes to improve the care of patients at-risk for developing critical illness outside the ICU.

Abstract
INTRODUCTION Existence of Advance Care Planning (ACP) documents including contact details of Medical Treatment Decision Makers (MTDM), are essential patient care records that support Emergency Department (ED) clinicians in implementing treatment concordant with patients' expressed wishes. Based upon previous findings, we conducted a statewide study to evaluate the performance of Victorian public hospital emergency departments on reporting of availability of records for ACP. METHOD The study is a quantitative retrospective observational comparative design based upon ED tier levels as defined by the Australasian College for Emergency Medicine (ACEM) for the calendar year 2021. RESULTS Of 1.8 million total Victorian ED attendances, 15,222 patients had an ACP alert status recorded. Of these, 7296 were aged ≥ 65 years (study group). Of the thirty-one public EDs that submitted data, 65 % were accredited and assigned a level of service tier. The presence of ACP alerts positively correlated to location, tier level, age and gender (MANOVA wilk's; p < 0.001, value=.981, F = (12, 15,300), partial ƞ2 = .006, observed power = 1.0 = 95.919). CONCLUSION The identified rate of ACP reporting is low. Strategies to improve the result include synchronising ACP (generated at different points) electronically, staff education, training and further validation of the data at the sending and receiving agencies.

Abstract
Objectives and outcomes To evaluate the 24hrs before medical emergency team (MET) calls to examine: 1) the frequency, nature, and timing of pre-MET criteria breaches; 2) differences in characteristics and outcomes between patients who did and didn't experience pre-MET breaches. Design Retrospective observational study November 2020-June 2021. Setting Tertiary referral Australian hospital. Participants Adults (≥18 years) experiencing MET calls. Results Breaches in pre-MET criteria occurred prior to 1886/2255 (83.6%) MET calls, and 1038/1281 (81.0%) of the first MET calls. Patients with pre-MET breaches were older (median [IQR] 72 [57-81] vs 66 [56-77] yrs), more likely to be admitted from home (87.8% vs 81.9%) and via the emergency department (73.0% vs 50.2%), but less likely to be for full resuscitation after (67.3% vs 76.5%) the MET. The three most common pre-MET breaches were low SpO2 (48.0%), high pulse rate (39.8%), and low systolic blood pressure (29.0%) which were present for a median (IQR) of 15.4 (7.5-20.8), 13.2 (4.3-21.0), and 12.6 (3.5-20.1) hrs before the MET call, respectively. Patients with pre-MET breaches were more likely to need intensive care admission within 24 h (15.6 vs 11.9%), have repeat MET calls (33.3 vs 24.7%), and die in hospital (15.8 vs 9.9%). Conclusions Four-fifths of MET calls were preceded by pre-MET criteria breaches, which were present for many hours. Such patients were older, had more limits of treatment, and experienced worse outcomes. There is a need to improve goals of care documentation and pre-MET management of clinical deterioration.

Abstract
Aim Rapid response systems (RRS) are present in many acute hospitals in western nations but are not widely adopted in Asia. The influence of healthcare culture and the effect of implementing an RRS over time are infrequently reported. We describe the introduction a RRS into a Singaporean hospital and the barriers encountered. The efferent limb activation rates, cardiac arrest rates and unplanned intensive care unit (ICU) admissions are trended over eleven years. Methods We conducted a retrospective observational study using prospectively collected data derived from administrative and Medical Emergency Team (MET) databases. Results The RRS used a MET with a single parameter track and trigger and physician led efferent limb. Barriers encountered included clinical leadership buy-in, assembling and equipping the efferent team, maintaining a non-punitive mindset, improving accessibility to MET and communicating the impact of the MET. Over an 11-year period with 488,252 hospital admissions, MET activation rates increased from 1.6/1000 admissions (2009) to 14.1/1000 admissions (2019). Code blue activations and unplanned ICU admission rates decreased from 2.9 to 1.7 and from 8.8 to 2.0/1000 admissions, respectively over the 11 years. There were associations between increasing MET activation rate and reduction in code blue activations (p = 0.013) and unplanned medical ICU admission rates (p = 0.001). Conclusion Implementing, sustaining and continued improvement of an RRS in Singapore is possible despite challenges encountered. With increasing activation rates over a decade, there were reductions in cardiac arrest rates and unplanned medical ICU admissions.

Abstract
BACKGROUND In-hospital cardiac arrest (IHCA) affects approximately 3000 patients annually in Australia. Introduction of the National Standard for Deteriorating Patients in 2011 was associated with reduced IHCA-related intensive care unit (ICU) admissions and reduced in-hospital mortality of such patients. AIMS To assess whether the reduction in IHCA-related ICU admissions from hospital wards seen following the implementation of the national standard (baseline period 2013-2014) was sustained over the follow-up period (2015-2019) in Australia. METHODS A multi-centre retrospective cohort study to compare the characteristics and outcomes of IHCA admitted to the ICU between baseline and follow-up periods. The primary outcome was the proportion of patients admitted to ICU from the ward following IHCA. Secondary outcomes included ICU and hospital mortality of IHCA-related ICU admissions. Data were analysed using hierarchical multivariable logistic regression. RESULTS The proportion of cardiac arrest-related admissions from the ward was lower in the follow-up period when compared to baseline (4.1 vs 3.8%; P = 0.04). Such patients had lower illness severity and were more likely to have limitations of medical treatment at admission. However, after adjustment for severity of illness, the likelihood of being admitted to ICU following cardiac arrest on the ward increased in the follow-up period (odds ratio (OR) 1.13 (1.05-1.22); P = 0.001). Hospital mortality was lower in the follow-up period (50.3 vs 46.3%; P = 0.02), but after adjustment the likelihood of death did not differ between the periods (OR 1.0 (0.86-1.17); P = 0.98). CONCLUSION After adjustment for the severity of illness, the likelihood of being admitted to ICU after IHCA slightly increased in the follow-up period.

Abstract
BACKGROUND Pre-medical emergency team (MET) calls are an increasingly common tier of Rapid Response Systems, but the epidemiology of patients who trigger a Pre-MET is not well understoof. OBJECTIVES This study aims to examine the epidemiology and outcomes of patients who trigger a pre-MET activation and identify risk factors for further deterioration. METHODS This is a retrospective cohort study of pre-MET activations in a university-affiliated metropolitan hospital in Australia, between 13 April 2021 and 4 October 2021. A multivariable regression model was used to identify variables associated with further deterioration, defined as a MET call or Code Blue within 24 h of pre-MET activation. RESULTS From a total of 39 664 admissions, there were 7823 pre-MET activations (197.2 per 1000 admissions). Compared to inpatients that did not trigger a pre-MET, the patients were older (68.8 vs 53.8 years, p < 0.001), were more likely to be male (51.0 vs 47.6%, p < 0.001), had an emergency admission (70.1% vs 53.3%, p < 0.001), and were under a medical specialty (63.7 vs 54.9%, p < 0.001). They had a longer hospital length of stay (5.6 vs 0.4 d, p < 0.001) and higher in-hospital mortality (3.4% vs 1.0%, p < 0.001). A pre-MET was more likely to progress to a MET call or Code Blue if it was activated for fever, cardiovascular, neurological, renal, or respiratory criteria (p < 0.001), if the patient was under a paediatric team (p = 0.018), or if there had been a MET call or Code Blue prior to the pre-MET activation (p < 0.001). CONCLUSION Pre-MET activations affect almost 20% of hospital admissions and are associated with a higher risk of mortality. Certain characteristics may predict further deterioration to a MET call or Code Blue, suggesting the potential for early intervention via clinical decision support systems.

Abstract
Utilizing a retrospective cohort study of SARS-CoV-2 wildtype (Wuhan) strain, we aimed to 1) utilize the unique Australian experience of temporarily eliminating SARS-CoV-2 to document and estimate the hospitalization demand; and 2) estimate the inpatient hospital costs associated with treatment. Case data was based on Victoria Australia from March 29 to December 31, 2020. Outcomes measures included hospitalization demand and case fatality ratio and inpatient hospitalization costs. Population adjusted results indicated that 10.2% (CI 9.9%-10.5%) required ward only admission, 1.0% (CI 0.9%-1.1%) required ICU admission plus 1.0% (CI 0.9%-1.1%) required ICU with mechanical ventilation. The overall case fatality ratio was 2.9% (CI 2.7%-3.1%). Mean ward only patient costs ranged from $22,714 to $57,100 per admission whilst ICU patient costs ranged from $37,228 to $140,455. With delayed, manageable outbreaks and public health measures leading to temporary elimination of community transmission, the Victorian COVID-19 data provides insight into initial pandemic severity and hospital costs.

Abstract
BACKGROUND Nurses and junior doctors are often the first clinicians to recognise signs of deterioration in patients. However, there can be barriers to having conversations about escalation of care. OBJECTIVES The aim of this study was to study the frequency and nature of barriers encountered during discussions related to escalation of care for deteriorating hospitalised patients. METHODS This was a prospective observational study with daily experience sampling surveys related to escalation of care discussions. The study setting involved two teaching hospitals in Victoria, Australia. Consented doctors, nurses, and allied health staff members involved in routine care of adult ward patients participated in the study. The main outcome measures included the frequency of escalation conversations and the frequency and nature of barriers encountered during such conversations. RESULTS/FINDINGS 31 clinicians participated in the study and completed an experience sampling survey 294 times, mean (standard deviation) = 9.48 (5.82). On 166 (56.6%) days, staff members were on clinical duties, and escalation of care discussions occurred on 67 of 166 (40.4%) of these days. Barriers to escalation of care occurred in 25 of 67 (37.3%) of discussions and most frequently involved lack of staff availability (14.9%), perceived stress in the contacted staff member (14.9%), perceptions of criticism (9.0%), being dismissed (7.5%), or indication of lack of clinical appropriateness in the response (6.0%). CONCLUSIONS Discussions related to escalation of care by ward clinicians occur in almost half of clinical days and are associated with barriers in one-third of discussions. Interventions are needed to clarify roles and responsibilities and outline behavioural expectations on both sides of the conversation and enable respectful communication amongst individuals involved in discussions of escalation of patient care.

Antecedents to and outcomes for in-hospital cardiac arrests in Australian hospitals with mature medical emergency teams: A multicentre prospective observational study. Aust Crit Care 2023; 36:1059-1066. [PMID: 37059632 DOI: 10.1016/j.aucc.2023.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 01/13/2023] [Accepted: 01/22/2023] [Indexed: 04/16/2023] Open
Abstract
BACKGROUND The epidemiology and predictability of in-hospital cardiac arrests (IHCAs) in hospitals with established medical emergency teams (METs) is underinvestigated. OBJECTIVES We categorised IHCAs into three categories: "possible suboptimal end-of-life planning" (possible SELP), "potentially predictable", or "sudden and unexpected" using age, Charlson Comorbidity Index, place of residence, functional independence, along with documented vital signs, K+ and HCO3 in the period prior to the IHCA. We also described the differences in characteristics and outcomes amongst these three categories of IHCAs. METHODS This was a prospective observational study (1st July 2017 to 9th August 2018) of adult (18 years) IHCA patients in wards of seven Australian hospitals with well-established METs. RESULTS Amongst 152 IHCA patients, 145 had complete data. The number (%) classified as possible SELP, potentially predictable, and sudden and unexpected IHCA was 50 (34.5%), 52 (35.8%), and 43 (29.7%), respectively. Amongst the 52 potentially predictable patients, six (11.5%) had missing vital signs in the preceding 6 hr, 18 (34.6%) breached MET criteria in the prior 24 hr but received no MET call, and 6 (11.5%) had a MET call but remained on the ward. Abnormal K+ and HCO3 was present in 15 of 51 (29.5%) and 13 of 51 (25.5%) of such patients, respectively. The 43 sudden and unexpected IHCA patients were mostly (97.6%) functionally independent and had the lowest median Charlson Comorbidity Index. In-hospital mortality for IHCAs classified as possible SELP, potentially predictable, and sudden and unexpected was 76.0%, 61.5%, and 44.2%, respectively (p = 0.007). Only four of 12 (33.3%) possible SELP survivors had a good functional outcome. CONCLUSIONS In seven Australian hospitals with mature METs, only one-third of IHCAs were sudden and unexpected. Improving end-of-life care in elderly comorbid patients and enhancing the response to objective signs of deterioration may further reduce IHCAs in the Australian context.

Clinicians' use and perceptions of the pre-medical emergency team tier of one rapid response system: A mixed-methods study. Aust Crit Care 2023; 36:1050-1058. [PMID: 36948918 DOI: 10.1016/j.aucc.2023.01.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 01/09/2023] [Accepted: 01/22/2023] [Indexed: 03/24/2023] Open
Abstract
BACKGROUND The pre-medical emergency team (pre-MET) tier of rapid response systems facilitates early recognition and treatment of deteriorating ward patients using ward-based clinicians before a MET review is needed. However, there is growing concern that the pre-MET tier is inconsistently used. OBJECTIVE This study aimed to explore clinicians' use of the pre-MET tier. METHODS A sequential mixed-methods design was used. Participants were clinicians (nurses, allied health, doctors) caring for patients on two wards of one Australian hospital. Observations and medical record audits were conducted to identify pre-MET events and examine clinicians' use of the pre-MET tier as per hospital policy. Clinician interviews expanded on understandings gained from observation data. Descriptive and thematic analyses were performed. RESULTS Observations identified 27 pre-MET events for 24 patients that involved 37 clinicians (nurses = 24, speech pathologist = 1, doctors = 12). Nurses initiated assessments or interventions for 92.6% (n = 25/27) of pre-MET events; however, only 51.9% (n = 14/27) of pre-MET events were escalated to doctors. Doctors attended pre-MET reviews for 64.3% (n = 9/14) of escalated pre-MET events. Median time between escalation of care and in-person pre-MET review was 30 min (interquartile range: 8-36). Policy-specified clinical documentation was partially completed for 35.7% (n = 5/14) of escalated pre-MET events. Thirty-two interviews with 29 clinicians (nurses = 18, physiotherapists = 4, doctors = 7) culminated in three themes: Early Deterioration on a Spectrum, A Safety Net, and Demands Versus Resources. CONCLUSIONS There were multiple gaps between pre-MET policy and clinicians' use of the pre-MET tier. To optimise use of the pre-MET tier, pre-MET policy must be critically reviewed and system-based barriers to recognising and responding to pre-MET deterioration addressed.

Abstract
OBJECTIVES The aims of the study are: (1) to evaluate the epidemiology of in-hospital cardiac arrests (IHCAs) 21 years after implementing a rapid response teams (RRTs); and (2) to summarize policies, procedures, and guidelines related to a national standard pertaining to recognition of and response to clinical deterioration in hospital. METHODS The study used a prospective audit of IHCA (commencement of external cardiac compressions) in ward areas between February 1, 2021, and January 31, 2022. Collation, summary, and presentation of material related to 8 "essential elements" of the Australian Commission for Safety and Quality in Health Care consensus statement on clinical deterioration. RESULTS There were 3739 RRT calls and 244 respond blue calls. There were 20 IHCAs in clinical areas, with only 10 occurring in general wards (0.36/1000 admissions). The median (interquartile range) age was 69.5 years (60-77 y), 90% were male, and comorbidities were relatively uncommon. Only 5 patients had a shockable rhythm. Survival was 65% overall, and 80% and 50% in patients on the cardiac and general wards, respectively. Only 4 patients had RRT criteria in the 24 hours before IHCA. A detailed summary is provided on policies and guidelines pertaining to measurement and documentation of vital signs, escalation of care, staffing and oversight of RRTs, communication for safety, education and training, as well as evaluation, audit, and feedback, which underpinned such findings. CONCLUSIONS In our mature RRT, IHCAs are very uncommon, and few are preventable. Many of the published barriers encountered in successful RRT use have been addressed by our policies and guidelines.

Automated rapid response system activation-Impact on nurses' attitudes and perceptions towards recognising and responding to clinical deterioration: Mixed-methods study. J Clin Nurs 2023; 32:6322-6338. [PMID: 37087695 DOI: 10.1111/jocn.16734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 02/12/2023] [Accepted: 04/05/2023] [Indexed: 04/24/2023]
Abstract
AIM To explore general ward nurses' attitudes and perceptions towards recognising and responding to clinical deterioration in a hospital with automated rapid response system activation. BACKGROUND There is growing interest in deploying automated clinical deterioration notification systems to reduce delayed or failed recognition and response to clinical deterioration of ward patients. However, little is known about its impact on ward nurses' perspectives and work patterns. DESIGN A mixed-methods study. METHODS Online survey of 168 registered nurses and individual interviews with 10 registered nurses in one acute hospital in Singapore. The study adhered to the STROBE checklist for cross-sectional studies and the COREQ guidelines for qualitative studies. RESULTS Many nurses (38.1%) rarely performed patient assessments or observations other than vital signs assessment to assess for early signs of clinical deterioration. About 30% were worried about being criticised for calling the primary team doctors. Four themes emerged from the qualitative analysis: automated rapid response system activation as a safety net, being more cautious with vital signs monitoring, the NEWS2 alone is inadequate, and ward nurses as the 'middleman' between the intensive care unit outreach nurse and primary team doctors. CONCLUSIONS Although nurses value the automated rapid response system activation as a safety net to minimise delays in accessing urgent critical care resources, it does not address the sociocultural barriers inherent in escalation of care. Although the automated system led nurses to be more cautious with vital signs monitoring, it does not encourage them to perform comprehensive patient assessments to detect early signs of deterioration. RELEVANCE TO CLINICAL PRACTICE Nurse education on assessing for clinical deterioration should focus on the use of broader patient assessment skills other than vital signs. Sociocultural barriers to escalation of care remain a key issue that needs to be addressed by hospital management. NO PATIENT OR PUBLIC CONTRIBUTION No patients, service users, care-givers or members of the public were involved in the study.

Abstract
Objective To introduce a management guideline for sepsis-related MET calls to increase lactate and blood culture acquisition, as well as prescription of appropriate antibiotics. Design Prospective before (Jun-Aug 2018) and after (Oct-Dec 2018) study was designed. Setting A public university linked hospital in Melbourne, Australia. Participants Adult patients with MET calls related to sepsis/infection were included. Main outcome measures The primary outcome measure was the proportion of MET calls during which both a blood culture and lactate level were ordered. Secondary outcomes included the frequency with which new antimicrobials were commenced by the MET, and the presence and class of administered antimicrobials. Results There were 985 and 955 MET calls in the baseline and after periods, respectively. Patient features, MET triggers, limitations of treatment and disposition after the MET call were similar in both groups. Compliance with the acquisition of lactates (p = 0.101), respectively. There was a slight reduction in compliance with lactate acquisition in the after period (97% vs 99%; p = 0.06). In contrast, there was a significant increase in acquisition of blood cultures in the after period (69% vs 78%; p = 0.035). Conclusions Introducing a sepsis management guideline and enhanced linkage with an AMS program increased blood culture acquisition and decreased broad spectrum antimicrobial use but didn't change in-hospital mortality.

Abstract
Objective To explore clinicians' use and perceptions of interdisciplinary communication pathways for escalating care within the pre-medical emergency team (pre-MET) tier of rapid response systems. Method A sequential mixed-methods study was conducted using observations and interviews. Participants were clinicians (nurses, allied health, doctors) caring for orthopaedic and general medicine patients at one hospital. Descriptive and thematic analyses were conducted. Results Escalation practices were observed for 13 of 27 pre-MET events. Leading communication methods for escalating pre-MET events were alphanumeric pagers (61.5%) and in-person discussions (30.8%). Seven escalated pre-MET events led to bedside pre-MET reviews by doctors. Clinician interviews (n = 29) culminated in two themes: challenges in escalation of care, and navigating information gaps. Clinicians reported deficiencies in communication methods for escalating care that hindered interdisciplinary communication and clinical decision-making pertaining to pre-MET deterioration. Conclusion Policy-defined escalation pathways were inconsistently utilised for pre-MET deterioration. Available communication methods for escalating pre-MET events inadequately fulfilled clinicians' needs. Variable perceptions of escalation pathways illuminated a lack of of a shared mental model about clinicians' roles and responsibilities. To optimise timely and appropriate management of patient deterioration, communication infrastructure and interdisciplinary collaboration must be enhanced.

Abstract
Purpose Since the introduction of National Emergency Access Targets (NEATs) in 2012 there has been little research examining patients admitted to the intensive care unit (ICU).We assessed differences in baseline characteristics and outcomes of patients admitted from the Emergency Department (ED) to the ICU within 4 hours compared with patients who were not. Methods This retrospective observational study included all adults (≥18 years old) admitted to the ICU from the ED of Austin Hospital, Melbourne, Australia, between 1 January 2017 and 31st December 2019 inclusive. Results 1544 patients were admitted from the ED to the ICU and 65% had an ED length of stay (EDLOS) > 4 hour. Such patients were more likely to be older, female, with less urgent triage category scores and lower illness severity. Sepsis and respiratory admission diagnoses, and winter presentations were significantly more prevalent in this group.After adjustment for confounders, patients with an EDLOS > 4 hours had lower hospital mortality; 8% v 21% (p = 0.029; OR, 1.62), shorter ICU length of stay 2.2 v 2.4 days (p = 0.043), but a longer hospital length of stay 6.2 v 6.8 days (p = < 0.001). Conclusion Almost two thirds of patients breached the NEAT of 4 hours. These patients were more likely to be older, female, admitted in winter with sepsis and respiratory diagnoses, and have lower illness severity and less urgent triage categories. NEAT breach was associated with reduced hospital mortality but an increased hospital length of stay.

Abstract
Objective This study aims to evaluate the characteristics and outcomes of patients who fulfilled extracorporeal membrane oxygenation cardiopulmonary resuscitation (E-CPR) selection criteria during in-hospital cardiac arrest (IHCA). Design This is a nested cohort study. Setting Code blue data were collected across seven hospitals in Australia between July 2017 and August 2018. Participants Participants who fulfilled E-CPR selection criteria during IHCA were included. Main outcome measures Return of spontaneous circulation and survival and functional outcome at hospital discharge. Functional outcome was measured using the modified Rankin scale, with scores dichotomised into good and poor functional outcome. Results Twenty-three (23/144; 16%) patients fulfilled E-CPR selection criteria during IHCA, and 11/23 (47.8%) had a poor outcome. Patients with a poor outcome were more likely to have a non-shockable rhythm (81.8% vs. 16.7%; p = 0.002), and a longer duration of CPR (median 12.5 [5.5, 39.5] vs. 1.5 [0.3, 2.5] minutes; p < 0.001) compared to those with a good outcome. The majority of patients (18/19 [94.7%]) achieved sustained return of spontaneous circulation within 15 minutes of CPR. All five patients who had CPR >15 minutes had a poor outcome. Conclusion Approximately one in six IHCA patients fulfilled E-CPR selection criteria during IHCA, half of whom had a poor outcome. Non-shockable rhythm and longer duration of CPR were associated with poor outcome. Patients who had CPR for >15 minutes and a poor outcome may have benefited from E-CPR. The feasibility, effectiveness and risks of commencing E-CPR earlier in IHCA and among those with non-shockable rhythms requires further investigation.

Abstract
Reactor neutrino experiments play a crucial role in advancing our knowledge of neutrinos. In this Letter, the evolution of the flux and spectrum as a function of the reactor isotopic content is reported in terms of the inverse-beta-decay yield at Daya Bay with 1958 days of data and improved systematic uncertainties. These measurements are compared with two signature model predictions: the Huber-Mueller model based on the conversion method and the SM2018 model based on the summation method. The measured average flux and spectrum, as well as the flux evolution with the ^{239}Pu isotopic fraction, are inconsistent with the predictions of the Huber-Mueller model. In contrast, the SM2018 model is shown to agree with the average flux and its evolution but fails to describe the energy spectrum. Altering the predicted inverse-beta-decay spectrum from ^{239}Pu fission does not improve the agreement with the measurement for either model. The models can be brought into better agreement with the measurements if either the predicted spectrum due to ^{235}U fission is changed or the predicted ^{235}U, ^{238}U, ^{239}Pu, and ^{241}Pu spectra are changed in equal measure.

Abstract
We present a new determination of the smallest neutrino mixing angle θ_{13} and the mass-squared difference Δm_{32}^{2} using a final sample of 5.55×10^{6} inverse beta-decay (IBD) candidates with the final-state neutron captured on gadolinium. This sample is selected from the complete dataset obtained by the Daya Bay reactor neutrino experiment in 3158 days of operation. Compared to the previous Daya Bay results, selection of IBD candidates has been optimized, energy calibration refined, and treatment of backgrounds further improved. The resulting oscillation parameters are sin^{2}2θ_{13}=0.0851±0.0024, Δm_{32}^{2}=(2.466±0.060)×10^{-3} eV^{2} for the normal mass ordering or Δm_{32}^{2}=-(2.571±0.060)×10^{-3} eV^{2} for the inverted mass ordering.

Abstract
Rapid reponse teams emerged 27 years ago to identify deteriorating patients and reduce preventable harm. There are concerns that such teams have deskilled hospital staff. However, over the past 20 years, there have been marked changes in hospital care and workplace requirements for hospital staff. In this article, we contend that hospital staff have been reskilled rather than deskilled.

Abstract
INTRODUCTION The development of professional portfolios and the relevance of this within professional practice, competency and capability is gaining significant credibility in line with professional requirements. Nursing and medicine in terms of historical perspectives have long held the need for clinicians to maintain a portfolio for professional validation, whilst in other professional groups it is a requirement of registration. The allied health professionals, physiotherapy and ultimately musculoskeletal practice within this context are rapidly developing advancing and consultant practice. This professional development further requires appropriate verification and validation of practice, and achieving this can be through formal and non-formal routes. PURPOSE This paper looks to explore this and give direction to professionals developing portfolios whilst placing the requirements in context to contemporary practice in the U.K. Universities, professional bodies and special interest groups are now aligning in the need to support practice in a multi-format way, that moves away from traditional methods of evaluation into more diverse models of competency-based assessment. IMPLICATIONS With improvement in technology, the development of national frameworks and standards, portfolios in practice although commonly considered as standard practice will be a requirement not only of registration but as a criteria of maintaining status, career development and expansion of roles. BACKGROUND Musculoskeletal (MSK) physiotherapy in the U.K. has moved forward significantly in the last 20 years. Sitting within a clinical reasoned framework, the introduction of additional skills such is image requesting, injection therapies, and non-medical prescribing has further underpinned the advanced practice agenda (Langridge et al., 2015). While these advancements in practice are driving the profession forward, challenges remain in providing the workforce with a clear process of career development. Alongside developing professional pathways methods of evidencing advanced knowledge and skills acquired outside formal routes are required to support practitioners' career pathway into advancing practice.

Abstract
PURPOSE Patients with cancer are vulnerable to clinical deterioration. Rapid response teams (RRTs) identify and manage patients with acute changes in clinical status. Although RRTs have been well studied in the hospital setting, there are limited data on patients who require support in the ambulatory or outpatient oncologic settings. Describe baseline characteristics, reasons for activations, interventions, and outcomes of ambulatory oncologic patients receiving RRT activation in a tertiary cancer center. METHODS We conducted a retrospective review of adult (age ≥ 18 years) patients requiring RRT activation at multiple ambulatory sites between July 2020 and June 2021. Demographic and clinical data captured include age, sex, race, ethnicity, do not resuscitate status, vital signs, receipt of active cancer treatment within 30 days, and cancer type. Using Kaplan-Meier survival analysis and multivariable Cox proportion hazard ratio regression models, outcomes of 90-day mortality and hospitalization were assessed. RESULTS There were 322 RRT activations among 427,734 visits to 10 ambulatory sites (0.75 RRTs/1,000 visits). The most frequent reasons were syncope (25.2%), fall (24.5%), and adverse reaction to cancer therapy or intravenous contrast (16.5%). One hundred thirty-seven (42.5%) required transfer to an emergency department, of which 81 (59.1%) required hospital admission. At 90 days, 51 (15.8%) had died, with 44 (86.3%) receiving comfort measures. Kaplan-Meier survival analysis and multivariable Cox proportional hazard ratio regression showed that heart rate > 100 at RRT presentation and hospitalization after a RRT event were significantly associated with 90-day mortality. CONCLUSION Although uncommon, patients with cancer undergoing care at ambulatory sites can suffer acute clinical deterioration needing RRT review. The rates of hospitalization and mortality among such patients are high, suggesting the need for improved end-of-life care.

Abstract
OBJECTIVES To develop and validate a prediction model to estimate the risk of Medical Emergency Team (MET) review, within 48 hours of an emergency admission, using information routinely available at the time of hospital admission. DESIGN Development and validation of a multivariable risk model using prospectively collected data. Transparent Reporting of a multivariable model for Individual Prognosis Or Diagnosis recommendations were followed to develop and report the prediction model. SETTING A 560-bed teaching hospital, with a 22-bed ICU and 24-hour Emergency Department in Melbourne, Australia. PATIENTS A total of 45,170 emergency admissions of 30,064 adult patients (≥18 yr), with an inpatient length of stay greater than 24 hours, admitted under acute medical or surgical hospital services between 2015 and 2017. MEASUREMENTS AND MAIN RESULTS The outcome was MET review within 48 hours of emergency admission. Thirty candidate variables were selected from a routinely collected hospital dataset based on their availability to clinicians at the time of admission. The final model included nine variables: age; comorbid alcohol-related behavioral diagnosis; history of heart failure, chronic obstructive pulmonary disease (COPD), or renal disease; admitted from residential care; Charlson Comorbidity Index score 1 or 2, or 3+; at least one planned and one emergency admission in the last year; and admission diagnosis and one interaction (past history of COPD × admission diagnosis). The discrimination of the model was comparable in the training (C-statistics 0.82; 95% CI, 0.81-0.83) and the validation set (0.81; 0.80-0.83). Calibration was reasonable for training and validation sets. CONCLUSIONS Using only nine predictor variables available to clinicians at the time of admission, the MET-risk model can predict the risk of MET review during the first 48 hours of an emergency admission. Model utility in improving patient outcomes requires further investigation.

Abstract
Abstract
Aspirin in combination with a P2Y12 inhibitor is the mainstay of treatment post percutaneous coronary intervention (PCI) for coronary artery disease (CAD). However, patients who are allergic to or intolerant to aspirin pose a therapeutic challenge especially when encountered in the setting of acute coronary syndrome. Aspirin desensitization strategies have been used in clinical practice to build tolerance prior to coronary intervention but clearly are not practical in the setting of ACS or significant symptomatic CAD. Low dose rivaroxaban (2.5 mg twice a day) has been previously shown to be safe in combination with a P2Y12 inhibitor post ACS compared to aspirin. We therefore sought to see if low dose rivaroxaban is a safe and effective alternative to aspirin in patients post PCI who are unable to take aspirin.This study aims to compare the efficacy (Major adverse cardiovascular events (MACE)) and safety (Bleeding events as defined by Bleeding Academic Research Consortium (BARC) criteria) in patients with confirmed aspirin allergy who were treated with low dose rivaroxaban therapy in place of aspirin in combination with P2Y12 inhibitors post PCI.
Methods
This was a single center observational study which looked at 50 cases of patients with aspirin allergy (47 cases) or significant confirmed aspirin intolerance (3 cases) who underwent PCI between December 2017 and February 2022. Patients were advised to take low dose rivaroxaban 2.5 mg twice a day as an alternative to aspirin 75 mg once a day. A comparator group of 50 matched patients without aspirin allergy who underwent PCI during the same time period and treated with standard aspirin therapy (75mg) along with a P2Y12 inhibitor. Outcomes over follow-up were MACE (mortality, myocardial infarction, stroke, and unscheduled revascularisation) and bleeding events defined by–BARC criteria.
Results
The median age of the aspirin allergy cohort was 62 years old with typical comorbidities associated with CAD. The cohort included a case mix of ACS and stable angina.The P2Y12 inhibitor in the majority of cases (76%) was Clopidogrel; Ticagrelor was used in 20% of cases and Prasugrel in 4% cases. No differences existed between the rivaroxaban and matched patient groups. The median follow-up as 626 days (Interquartile range 237–549). The duration of low dose rivaroxaban therapy was for 12 months with a P2Y12 in 72%, 1–3 months for 22% and finally continued long term (with P2Y12 discontinuation at 12 months) in 6%. No difference existed in the incidence of MACE between the low dose rivaroxaban group (12%) compared to the matched cohort (10% p=0.266). No difference in bleeding outcomes (any bleeding event BARC type >0) were seen (14% in rivaroxaban and 16% in control, p=0.329).
Conclusions
This study provides more supporting evidence that low dose rivaroxaban therapy is an alternative to aspirin when used in combination with a P2Y12 inhibitor post PCI.

Abstract
Abstract
Background
The Ticagrelor with Aspirin or Alone in High-Risk Patients after Coronary Intervention (TWILIGHT) randomized clinical trial demonstrated that in selected high risk patients who took ticagrelor and aspirin for 3 months after percutaneous coronary intervention (PCI), continuing ticagrelor alone was associated with significantly less bleeding events than ticagrelor plus aspirin and did not lead to ischemic harm over a period of 1 year (1).
The prevalence and risk of adverse events of patients fulfilling the TWILIGHT inclusion criteria in real-world setting is unclear.
Purpose
To elucidate the prevalence and prognosis of patients fulfilling the TWILIGHT inclusion criteria.
Methods
Patients that received at least one drug eluting stent in a coronary artery at a large tertiary center (Mount Sinai Hospital, New York) were considered for inclusion. As in the TWILIGHT trial, individuals on chronic oral anticoagulation treatment, with STEMI, cardiogenic shock, on dialysis, with prior stroke, or platelet count <100,000 were excluded. Patients were stratified in two groups: 1) TWILIGHT-like patients, who met at least one clinical (age ≥65 years, female sex, established vascular disease, diabetes mellitus, estimated glomerular fraction rate <60mL/min, acute coronary syndrome with troponin increase) and one angiographic (multivessel coronary artery disease [CAD], stent length >30mm, thrombotic target lesion, bifurcation requiring 2 stents, left main or proximal left anterior descending artery lesion, atherectomy device use, SYNTAX score ≥23) TWILIGHT inclusion criterion; 2) Non-TWILIGHT-like patients, who did not fulfil at least one clinical and one angiographic TWILIGHT inclusion criterion.
The primary outcome was a composite of death, myocardial infarction (MI), stroke. Secondary outcomes included bleeding, components of the primary outcome, target vessel and target lesion revascularization, stent thrombosis. All events were assessed at 1 year after PCI.
Results
Out of 30,470 patients undergoing PCI between 2012 and 2019, 13,236 were included in the current analysis. TWILIGHT criteria were met in 11,018 (83%) patients. Established vascular disease and multivessel CAD were the most frequently fulfilled criteria. At 1 year, TWILIGHT-like patients were at higher risk for the primary outcome (3.2% vs 1.1%, HR 2.85, 95% CI 1.83–4.44), severe bleeding (3.3% vs 1.8%, HR 1.86, 95% CI 1.32–2.62), all-cause death (1.4% vs 0.4%, HR 3.63, 95% CI 1.70–7.77), myocardial infarction (1.8% vs 0.6%, HR 2.81 95% CI 1.56–5.04), TVR (7.8% vs 4.1%, HR 1.94, 95% CI 1.53–2.47), TLR (5.1% vs 1.7%, HR 2.98 95% CI 2.07–4.29). Stent thrombosis and stroke rate were generally low and did not differ between patients meeting or not the TWILIGHT inclusion criteria.
Conclusion
Among all-comer patients undergoing PCI, the fulfillment of the TWILIGHT inclusion criteria is frequent and is associated with a higher risk of death, ischemic and bleeding complications

Abstract
Abstract
Background
It has been previously reported during the first COVID outbreak that patients presenting with ST-Segment Elevation Myocardial Infarction (STEMI) and concurrent COVID-19 infection have increased thrombus burden and poorer outcomes [1]. Subsequently, there have been multiple further waves of the pandemic with the emergence of at least two new COVID-19 variants and the emergence of vaccinations. To-date, there have been no reports comparing the outcomes of COVID-19-positive STEMI patients across all waves of the pandemic.
Purpose
The purpose of this study was to compare the baseline demographic, procedural and angiographic characteristics alongside the clinical outcomes of patients presenting with STEMI and concurrent COVID-19 infection across the COVID-19 pandemic in the UK.
Methods
This was a single-centre, observational study of 1250 consecutive patients admitted with confirmed STEMI treated with primary percutaneous coronary intervention (PCI) at Barts Heart Centre between 01/03/2020 and 10/03/2022. COVID +ve patients were split into 3 groups based upon the time course of the pandemic (Wave 1: March 2020-June 2020, Wave 2: Sept 2020-March 2021, Wave 3: October 2021-March 2022). Comparison was made between waves and with a control group of COVID-ve patients treated during the same timeframe.
Results
A total of 135 COVID +ive patients with STEMI (1st Wave: 39 patients, 2nd Wave: 60 patients, 3rd wave 35 pts) were included in the present analysis; and compared with 1115 COVID negative patients. Significant changes in the baseline characteristics, angiographic features and clinical outcomes of COVID +ive patients occurred over time. Early during the pandemic (Wave 1 2020), STEMI patients presenting with concurrent COVID-19 infection had high rates of cardiac arrest, evidence of increased thrombus burden (higher rates of multi-vessel thrombosis, stent thrombosis, higher modified thrombus grade higher use of GP IIb/IIIa inhibitors and thrombus aspiration, coagulability (more heparin for therapeutic ACT), bigger infarcts (lower myocardial blush grade and left ventricular function) and worse outcomes (mortality). However, by wave 3 (late 2021/2022), no differences existed in clinical characteristics, thrombus burden, infarct size or outcomes between COVID +ive patients and those without concurrent COVID-19 infection with significant differences compared to earlier COVID +ve patients. Poor outcomes later in the study period were predominantly in unvaccinated individuals.
Conclusions
Significant changes have occurred in the clinical characteristics, angiographic features and outcomes of STEMI patients with COVID-19 infection treated by primary PCI during the course of the pandemic. Importantly it appears that angiographic features and outcomes of recent waves are no different to a non-COVID-19 population.

Abstract
Abstract
Background
Recent advances in drug eluting stents (DES) design have significantly decreased the rates of in-stent restenosis (ISR). Nonetheless, ISR remains a major problem, affecting 5–10% of patients undergoing percutaneous coronary intervention (PCI). Furthermore, PCI for ISR is often a poor prognostic factor for outcomes after the procedure. Historically, obese patients tended to have better outcomes when undergoing PCI, however it is unclear if this trend continues for the same population undergoing PCI for ISR.
Purpose
Investigate the outcomes of patients undergoing PCI for ISR in the overweight and normal weight population.
Methods
All patients undergoing PCI with DES implantation at a tertiary care center from January 2012 to December 2019 were included. Normal weight was defined as a body mass index (BMI) greater than or equal to 18.5 kg/m2 and less than 25 kg/m2, while overweight was defined as a BMI greater than or equal to 25 kg/m2. Patients with BMI <18.5 kg/m2, underwent PCI for acute myocardial infarction (MI), or received a bare metal stent (BMS) were excluded. The primary outcome was major events (MACE), a composite of all-cause mortality, myocardial infarction (MI), and target vessel revascularization (TVR) up to one year after PCI. Secondary outcomes included individual components of the primary endpoint.
Results
Out of 16,234 patients with available data on BMI, 12,444 (76.7%) were overweight and 3,790 (23.3%) were normal weight. Among overweight patients, 2,879 (23.1%) underwent PCI for ISR versus 815 (21.5%) of normal weight patients. Regardless of BMI status, patients undergoing PCI for ISR had higher rates of co-morbidities such as hypertension, hyperlipidemia, and diabetes mellitus than non-ISR counterparts. At one year post PCI, both overweight and normal weight patients undergoing PCI for ISR had increased risk of MACE (overweight: 18.4% vs. 6.7%; HR 2.83; 95% CI 2.50–3.20; normal weight: 18.8% vs. 7.8%, HR 2.43, 95% CI 1.95–3.04) when compared to non-ISR counterparts, mostly driven by TVR (overweight: 16% vs. 4.6%; HR 3.58; 95% CI 3.11–4.13; normal weight: 15.2% vs. 4.1%; HR 3.69; 95% CI 2.80–4.86). However, only overweight patients undergoing PCI for ISR had higher risk of all cause mortality (2.2% vs. 1.5%; HR 1.42; 95% CI 1.03–1.95) and MI (3.0% vs. 1.3%, HR 2.22; 95% CI 1.64–2.99) when compared to non-ISR counterparts (Figure 1).
Conclusions
PCI for ISR was associated with increased risk of MACE, irrespective of body weight. The risks of all-cause mortality and MI in ISR vs non-ISR patients only reached statistical significance in overweight patients.

Abstract
Abstract
Background
Left ventricular thrombus (LVT) complicates around one in six cases of acute and chronic left ventricular systolic dysfunction and is associated with an increased risk of stroke, major systemic embolism and death, believed to be ameliorated by anticoagulation. Off-label use of direct oral anticoagulants (DOACs) for LVT has steadily increased, largely based on favourable outcomes in atrial fibrillation and venous thromboembolism, but the safety and efficacy of DOACs versus vitamin K antagonists (VKA) for LVT remains uncertain.
Purpose
The main aim of our study was to compare treatment of LVT with VKA to DOAC, focusing on all-cause mortality, stroke, major systemic emboli and major bleeding.
Methods
We conducted a retrospective observational longitudinal study of patients presenting to two large quaternary centres between 2011 and 2021 with a diagnosis of LVT. Patients were eligible if they had a documented LVT and received anticoagulation with either VKA or DOAC. Baseline data, thrombus characteristics, treatment type and duration, follow up imaging and clinical events were recorded using electronic health care records. Outcome measures included thrombus resolution, stroke and systemic embolism (SSE), major bleeding and mortality.
Results
A total of 955 patients were identified, of whom 901 received treatment with either a VKA (567 pts, 62.9%) or a DOAC (334 pts, 37.1%) and were included in the analysis. Underlying aetiologies included acute myocardial infarction (AMI) (38.3%), chronic ischaemic cardiomyopathy (38.0%) and non-ischaemic cardiomyopathy (23.7%). Rivaroxaban (43.4%) was the most frequently prescribed DOAC followed by apixaban (35.9%), and the remaining on edoxaban (20.7%). AMI related LVT was more commonly treated with DOAC (53.0%) and chronic ischaemic cardiomyopathy with VKA (72.9%).
There was a lower baseline LVEF in the VKA cohort (29.5±13.2 vs 33.1±14.2, p<0.0001). Other demographic features were comparable. Median follow up was 2.5 years (IQR: 1–3.5). There were no differences in follow up duration between the two treatments (p=0.17). Greater rates of thrombus resolution were seen in the DOAC group compared to VKA (1 year: 78.4% vs 51.4%, p<0.0001), with higher rates of persistent thrombus over the follow-up period seen in the VKA group (25.1% vs 12.9%, p<0.0001). Rates of stroke and systemic embolization were similar between the groups (VKA 9.3% vs 9.6% DOAC, p=0.93). Higher rates of bleeding (BARC >3, 8.1% VKA, 3.6% DOAC, p=0.031) (Figure 1A) and mortality (VKA 18.5%, DOAC 10.2%, p=0.001) (Figure 1B) were seen in the VKA group over the follow-up period.
Conclusions
In a large multi-centre registry of LVT of mixed aetiology, anticoagulation with DOAC was associated with earlier and greater rates of thrombus resolution and consequential reduced adverse events (major bleeding and mortality) during follow up. A funding application to support a multi-centre randomised control trial is underway.

Abstract
INTRODUCTION Most patients admitted to hospital recover with treatments that can be administered on the general ward. A small but important group deteriorate however and require augmented organ support in areas with increased nursing to patient ratios. In observational studies evaluating this cohort, proxy outcomes such as unplanned intensive care unit admission, cardiac arrest and death are used. These outcome measures introduce subjectivity and variability, which in turn hinders the development and accuracy of the increasing numbers of electronic medical record (EMR) linked digital tools designed to predict clinical deterioration. Here, we describe a protocol for developing a new outcome measure using mixed methods to address these limitations. METHODS AND ANALYSIS We will undertake firstly, a systematic literature review to identify existing generic, syndrome-specific and organ-specific definitions for clinically deteriorated, hospitalised adult patients. Secondly, an international modified Delphi study to generate a short list of candidate definitions. Thirdly, a nominal group technique (NGT) (using a trained facilitator) will take a diverse group of stakeholders through a structured process to generate a consensus definition. The NGT process will be informed by the data generated from the first two stages. The definition(s) for the deteriorated ward patient will be readily extractable from the EMR. ETHICS AND DISSEMINATION This study has ethics approval (reference 16399) from the Central Adelaide Local Health Network Human Research Ethics Committee. Results generated from this study will be disseminated through publication and presentation at national and international scientific meetings.

Abstract
BACKGROUND Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery. METHODS A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed. RESULTS Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011). CONCLUSION The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Abstract
Objectives: To investigate the prevalence and features of self-reported burnout among intensivists working in Australia and New Zealand, and evaluate potentially modifiable workplace stressors associated with increased risk of self-reported burnout. Methods: We performed an electronic survey among registered intensivists in Australia and New Zealand. Burnout and professional quality of life were measured using the Professional Quality of Life Scale version 5 (ProQOL-5). Socio-organisational factors were defined a priori and assessed using a five-point Likert scale. Thematic analysis was conducted on an open-ended question on workplace stressors. Results: 261 of 921 estimated intensivists responded (response rate, 28.3%). Overall, few participants (0.8%) demonstrated high scores (> 75th centile) for burnout, and 70.9% of participants scored in the average range for burnout. Of note, 98.1% of participants scored in the average to high range for compassion satisfaction. No association was found between sex, age, or years of practice with the level of burnout or compassion satisfaction. Seven themes emerged regarding intensivists' most stressful aspects of work: interpersonal interactions and workplace relationships (25.5%), workload and its impact (24.9%), resources and capacity (22.6%), health systems leadership and bureaucracy (16.1%), end-of-life issues and moral distress (8.4%), clinical management (4.9%), and job security and future uncertainty (1.3%). Conclusion: Fewer Australian and New Zealand intensivists experienced burnout than previously reported. Many self-reported work stressors do not relate to clinical work and are due to interpersonal interactions with other colleges and hospital administrators. Such factors are potentially modifiable and could be the focus of future interventions.

Abstract
Background
Histone 3 lysine27-to-methionine mutations (H3-K27M) frequently occur in childhood diffuse midline gliomas (DMGs) of the pons, thalamus and spinal cord, presumed to be driven by the specific spatiotemporal context of these midline locations during postnatal development. While most common in the pons and at mid-childhood ages, the same oncohistone mutation is recurrently detected in adult DMGs and throughout different midline regions. The potential heterogeneity of tumors at different ages and in different anatomical locations of the midline are vastly understudied.
Material and Methods
Through dissecting the transcriptomic, epigenomic and spatial architectures of a comprehensive cohort of patient H3-K27M DMGs - spanning the age range from 2-68 years and locations from spinal cord to thalamus - at single cell resolution, we delineate how age- and location-dependent contexts shape glioma cell-intrinsic and -extrinsic features in light of the shared driver mutation.
Results
We identify that oligodendrocyte precursor (OPC)-like cells constitute the stem-like compartment in H3-K27M DMGs across all clinico-anatomical groups, however, depending on location, display varying levels of maturity resembling less differentiated pre-OPCs or more mature OPCs further differentiated along the oligodendroglial lineage. We further demonstrate increased mesenchymal cell states in adult tumors, which we link to age-related differences in glioma-associated immune cell compartments. We for the first time resolve the spatial organization of H3-K27M DMG cell types in intact patient tissues, identifying a local niche of the oligodendroglial lineage.
Conclusion
Our study provides a powerful resource for rational modeling and therapeutic frameworks taking into account determinants of age and location in this lethal glioma group.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.
