From a Single Voice to Diversity: Reframing 'Representation' in Patient Engagement.

There has been a growing emphasis on consumer representation in the development of health policy, services, research, and education. Existing literature has critiqued how discourses of representativeness can disempower consumers working in health systems. The context of the current study is consumer engagement in the development of COVID-19 triage policy and practice in a local health service. Consumer engagement has often been an afterthought in the COVID response, with few examples of consumers in agenda-setting or decision-making roles. In the Australian Capital Territory, 26 consumer, carer, and community groups worked together with academics and clinicians to develop these principles. Interviews were conducted with stakeholders (including consumers, clinicians, and other health professionals) to evaluate the development of triage principles. A discursive psychological approach to analysis was used to explore participants' understandings about and constructions of consumers being representative (or not) and how this may reproduce power imbalances against consumers. The results explore two distinct ways in which participants talked about consumer representativeness: the first drawing on rhetoric about consumers as lay members of the public (as distinct from being professionally engaged in the health sector), and the second in terms of consumer representatives being diverse and having intersectional identities and experiences. Expectations about consumers to be representative of the general population may reproduce traditional power imbalances and silence lived experience expertise. These power imbalances may be challenged by a shift in the way representativeness is conceptualised to requiring health services to seek out diverse and intersectionally marginalised consumers.

Characteristics and Outcomes of Very Elderly Patients Admitted to Intensive Care: A Retrospective Multicenter Cohort Analysis.

OBJECTIVES: To characterize and compare trends in ICU admission, hospital outcomes, and resource utilization for critically ill very elderly patients (≥ 80 yr old) compared with the younger cohort (16-79 yr old). DESIGN: A retrospective multicenter cohort study. SETTING: One-hundred ninety-four ICUs contributing data to the Australian and New Zealand Intensive Care Society Centre for Outcome and Resource Evaluation Adult Patient Database between January 2006 and December 2018. PATIENTS: Adult (≥ 16 yr) patients admitted to Australian and New Zealand ICUs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Very elderly patients with a mean ± sd age of 84.8 ± 3.7 years accounted for 14.8% (232,582/1,568,959) of all adult ICU admissions. They had higher comorbid disease burden and illness severity scores compared with the younger cohort. Hospital (15.4% vs 7.8%, p < 0.001) and ICU mortality (8.5% vs 5.2%, p < 0.001) were higher in the very elderly. They stayed fewer days in ICU, but longer in hospital and had more ICU readmissions. Among survivors, a lower proportion of very elderly was discharged home (65.2% vs 82.4%, p < 0.001), and a higher proportion was discharged to chronic care/nursing home facilities (20.1% vs 7.8%, p < 0.001). Although there was no change in the proportion of very elderly ICU admissions over the study period, they showed a greater decline in risk-adjusted mortality (6.3% [95% CI, 5.9%-6.7%] vs 4.0% [95% CI, 3.7%-4.2%] relative reduction per year, p < 0.001) compared with the younger cohort. The mortality of very elderly unplanned ICU admissions improved faster than the younger cohort ( p < 0.001), whereas improvements in mortality among elective surgical ICU admissions were similar in both groups ( p = 0.45). CONCLUSIONS: The proportion of ICU admissions greater than or equal to 80 years old did not change over the 13-year study period. Although their mortality was higher, they showed improved survivorship over time, especially in the unplanned ICU admission subgroup. A higher proportion of survivors were discharged to chronic care facilities.

"I can't make all this work." End of life care provision in natural disasters: a qualitative study.

BACKGROUND: Natural disasters are becoming more frequent and severe and profoundly impact the end-of-life care experience, including service provision. There is a paucity of research examining healthcare workers' experiences in responding to care demands when disasters strike. This research aimed to fill this gap by exploring end-of-life care providers' perceptions of the impact of natural disasters on end-of-life care. METHODS: Between Feb 2021-June 2021 ten in-depth semi-structured interviews were conducted with healthcare professionals providing end-of-life care during recent natural disasters, COVID-19, and/or fires and floods. Interviews were audio-recorded, transcribed, and analysed using a hybrid inductive and deductive thematic approach. RESULTS: The overarching theme from the healthcare workers' accounts was of being unable to provide effective compassionate and quality care - "I can't make all this work." They spoke of the considerable burdens the system imposed on them, of being overextended and overwhelmed, having their roles overturned, and losing the human element of care for those at end-of-life. CONCLUSION: There is urgent need to pioneer effective solutions to minimise the distress of healthcare professionals in delivering end-of-life care in disaster contexts, and to improve the experience of those dying.

The "affected" pharmacist and the "business as usual" pharmacist: Exploring the experiences of pharmacists during COVID-19 through cluster analysis.

BACKGROUND: The global coronavirus disease 2019 (COVID-19) pandemic has necessitated considerable changes in the delivery of pharmacy services, with pharmacists experiencing increasing demands and a high rate of burnout. The ability to categorize pharmacists based on their burnout risk and associated factors could be used to tailor burnout interventions. OBJECTIVE: This study aimed to identify subgroups (profiles) of pharmacists and use these profiles to describe interventions tailored to improve pharmacist's well-being. METHODS: A survey was disseminated to pharmacists working in Australia during April and June 2020. The survey measured demographics, burnout, and psychosocial factors associated with working during COVID-19. A two-step cluster analysis was used to categorize pharmacists based on burnout and other variables. RESULTS: A total of 647 survey responses contained data that were used for analysis. Participants were mostly female (75.7%) and working full time (65.2%). The final cluster analysis yielded an acceptable two-cluster model describing 2 very different pharmacist experiences, using 10 variables. Cluster 2 (representing 53.1% of participants) describes the "affected" pharmacist, who has a high degree of burnout, works in community pharmacy, experiences incivility, is less likely to report sufficient precautionary measures in their workplace, and has had an increase in workload and overtime. In contrast, cluster 1 (representing 46.9% of participants) describes the profile of a "business as usual" hospital pharmacist with the opposite experiences. Interventions focused on the "affected" pharmacist such as financial support to employ specialized staff and equitable access to personal protective equipment should be available to community pharmacists, to reduce the risk to these frontline workers. CONCLUSION: The use of cluster analysis has identified 2 distinct profiles of pharmacists working during COVID-19. The "affected" pharmacist warrants targeted interventions to address the high burnout experienced in this group.

Vital sign assessment and nursing interventions in medical and surgical patients with rapid response system triggers.

AIM(S): To explore vital sign assessment (both complete and incomplete sets of vital signs), and escalation of care per policy and nursing interventions in response to clinical deterioration. DESIGN: This cohort study is a secondary analysis of data from the Prioritising Responses of Nurses To deteriorating patient Observations cluster randomised controlled trial of a facilitation intervention on nurses' vital sign measurement and escalation of care for deteriorating patients. METHODS: The study was conducted in 36 wards at four metropolitan hospitals in Victoria, Australia. Medical records of all included patients from the study wards during three randomly selected 24-h periods within the same week were audited at three time points: pre-intervention (June 2016), and at 6 (December 2016) and 12 months (June 1017) post-intervention. Descriptive statistics were used to summarise the study data, and relationships between variables were examined using chi-square test. RESULTS: A total of 10,383 audits were conducted. At least one vital sign measurement was documented every 8 h in 91.6% of audits, and a complete set of vital signs was documented every 8 h in 83.1% of audits. There were pre-Medical Emergency Team, Medical Emergency Team or Cardiac Arrest Team triggers in 25.8% of audits. When triggers were present, a rapid response system call occurred in 26.8% of audits. There were 1350 documented nursing interventions in audits with pre-Medical Emergency Team (n = 2403) or Medical Emergency Team triggers (n = 273). One or more nursing interventions were documented in 29.5% of audits with pre-Medical Emergency Team triggers and 63.7% of audits with Medical Emergency Team triggers. CONCLUSION: When rapid response system triggers were documented, there were gaps in escalation of care per policy; however, nurses undertook a range of interventions within their scope of practice in response to clinical deterioration. RELEVANCE TO CLINICAL PRACTICE: Medical and surgical ward nurses in acute care wards frequently engage in vital sign assessment. Interventions by medical and nurgical nurses may occur prior to, or in parallel with calling the rapid response system. Nursing interventions are a key but under-recognised element of the organisational response to deteriorating patients. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Nurses engage in a range of nursing interventions to manage deteriorating patients, (aside from rapid response system activation) that are not well understood, nor well described in the literature to date. IMPACT: This study addresses the gap in the literature regarding nurses' management of deteriorating patients within their scope of practice (aside from RRS activation) in real world settings. When rapid response system triggers were documented, there were gaps in escalation of care per policy; however, nurses undertook a range of interventions within their scope of practice in response to clinical deterioration. The results of this research are relevant to nurses working on medical and surgical wards. REPORTING METHOD: The trial was reported according to the Consolidated Standards of Reporting Trials extension for Cluster Trials recommendations, and this paper is reported according to the Strengthening the Reporting of Observational Studies in Epidemiology Statement. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

What are the long-term holistic health consequences of COVID-19 among survivors? An umbrella systematic review.

Many people who have survived COVID-19 have experienced negative persistent impacts on health. Impacts on health have included persistent respiratory symptoms, decreased quality of life, fatigue, impaired functional capacity, memory deficits, psychological impacts, and difficulties in returning to paid employment. Evidence is yet to be pooled to inform future directions in research and practice, to determine the physical, psychological, social, and spiritual impacts of the illness which extend beyond the acute phase of COVID-19 survivors. This umbrella review (review of systematic reviews) critically synthesized physical (including abnormal laboratory parameters), psychological, social, and spiritual impacts which extended beyond the acute phase of COVID-19 survivors. The search strategy was based on the sample, phenomena of interest, design, evaluation, research model and all publications were double screened independently by four review authors for the eligibility criteria. Data extraction and quality assessment were conducted in parallel independently. Eighteen systematic reviews were included, which represented a total of 493 publications. Sample sizes ranged from n = 15 to n = 44 799 with a total of n = 295 455 participants. There was incomplete reporting of several significant data points including the description of the severe acute respiratory syndrome coronavirus 2 variant, COVID-19 treatments, and key clinical and demographic data. A number of physical, psychological, and social impacts were identified for individuals grappling with post-COVID condition. The long term sequalae of acute COVID-19 and size of the problem is only beginning to emerge. Further investigation is needed to ensure that those affected by post-COVID condition have their informational, spiritual, psychological, social, and physical needs met in the future.

Intensive care doctors and nurses personal preferences for Intensive Care, as compared to the general population: a discrete choice experiment.

BACKGROUND: To test the hypothesis that Intensive Care Unit (ICU) doctors and nurses differ in their personal preferences for treatment from the general population, and whether doctors and nurses make different choices when thinking about themselves, as compared to when they are treating a patient. METHODS: Cross sectional, observational study conducted in 13 ICUs in Australia in 2017 using a discrete choice experiment survey. Respondents completed a series of choice sets, based on hypothetical situations which varied in the severity or likelihood of: death, cognitive impairment, need for prolonged treatment, need for assistance with care or requiring residential care. RESULTS: A total of 980 ICU staff (233 doctors and 747 nurses) participated in the study. ICU staff place the highest value on avoiding ending up in a dependent state. The ICU staff were more likely to choose to discontinue therapy when the prognosis was worse, compared with the general population. There was consensus between ICU staff personal views and the treatment pathway likely to be followed in 69% of the choices considered by nurses and 70% of those faced by doctors. In 27% (1614/5945 responses) of the nurses and 23% of the doctors (435/1870 responses), they felt that aggressive treatment would be continued for the hypothetical patient but they would not want that for themselves. CONCLUSION: The likelihood of returning to independence (or not requiring care assistance) was reported as the most important factor for ICU staff (and the general population) in deciding whether to receive ongoing treatments. Goals of care discussions should focus on this, over likelihood of survival.

The burden of COVID-19 on pharmacists.

The unprecedented changes brought about by the global coronavirus disease 2019 (COVID-19) pandemic have had important impacts on society. The pandemic has provided an opportunity to highlight the crucial role pharmacists play in the provision of health care. The critical and unique role of pharmacists in pandemics and other disasters has been highlighted in the past (severe acute respiratory syndrome and Ebola outbreaks) and more recently with reports of the contributions of pharmacists during the global COVID-19 pandemic. Many reports have documented that health care professionals are experiencing significant psychological morbidity as a result of providing essential care and services during the global COVID-19 pandemic. In these reports, pharmacists are not well represented, and, therefore, it is essential to understand the impact of COVID-19 on pharmacists across multiple practice settings. This is particularly true as the experiences of pharmacists working through previous pandemics and disasters, and the associated psychological burden, are likely to offer insights and be useful in supporting the psychological well-being of pharmacists during the global COVID-19 pandemic. Research into the effect of the global COVID-19 pandemic on pharmacists should improve the understanding of the impact and the psychological morbidity associated with their role as frontline health care professionals.

Barriers to rehabilitation after critical illness: a survey of multidisciplinary healthcare professionals caring for ICU survivors in an acute care hospital.

BACKGROUND: There is scant literature on the barriers to rehabilitation for patients discharged from the intensive care unit (ICU) to acute care wards. OBJECTIVES: The objective of this study was to assess ward-based rehabilitation practices and barriers and assess knowledge and perceptions of ward clinicians regarding health concerns of ICU survivors. METHODS, DESIGN, SETTING, AND PARTICIPANTS: This was a single-centre survey of multidisciplinary healthcare professionals caring for ICU survivors in an Australian tertiary teaching hospital. MAIN OUTCOME MEASURES: The main outcome measures were knowledge of post-intensive care syndrome (PICS) amongst ward clinicians, perceptions of ongoing health concerns with current rehabilitation practices, and barriers to inpatient rehabilitation for ICU survivors. RESULTS: The overall survey response rate was 35% (198/573 potential staff). Most respondents (66%, 126/190) were unfamiliar with the term PICS. A majority of the respondents perceived new-onset physical weakness, sleep disturbances, and delirium as common health concerns amongst ICU survivors on acute care wards. There were multifaceted barriers to patient mobilisation, with inadequate multidisciplinary staffing, lack of medical order for mobilisation, and inadequate physical space near the bed as common institutional barriers and patient frailty and cardiovascular instability as the commonly perceived patient-related barriers. A majority of the surveyed ward clinicians (66%, 115/173) would value education on health concerns of ICU survivors to provide better patient care. CONCLUSION: There are multiple potentially modifiable barriers to the ongoing rehabilitation of ICU survivors in an acute care hospital. Addressing these barriers may have benefits for the ongoing care of ICU survivors.

Consumer and carer leadership in palliative care academia and practice: A systematic review with narrative synthesis.

BACKGROUND: Contemporary health policies call for consumers to be part of all aspects of service planning, implementation, delivery and evaluation. The extent to which consumers are part of the systemic decision-making levels of palliative care appears to vary between and within services and organisations. AIM: The aim of this systematic review is to develop understandings about consumer and carer leadership in palliative care. DESIGN: A systematic, narrative synthesis approach was adopted due to the heterogeneity of included studies. The review was registered on PROSPERO prospectively (PROSPERO 2018 CRD42018111625). DATA SOURCES: PubMed, Scopus and PsycINFO were searched for all studies published in English specifically focusing on consumers' leadership in palliative care organisations and systems. Articles were appraised for quality using a modified JBI-QARI tool. RESULTS: Eleven studies met the inclusion criteria and quality assessment. Consumers are currently involved in leadership of palliative care teaching, research and services. Findings highlight the benefits of consumer leadership in palliative care including more relevant, higher-quality services, teaching and research. Across the included studies, it was not clear the extent to which consumer leaders had influence in relation to setting agendas across the palliative care sector. CONCLUSION: The findings suggest that more could be done to support consumer leadership within palliative care. Academics and clinicians might improve the relevance of their work if they are able to more meaningfully partner with consumers in systemic roles in palliative care.

Recognising and managing dying patients in the acute hospital setting: can we do better?

Healthcare professionals have limited formal end-of-life care training despite the large proportion of hospital deaths. A retrospective review of 201 acute hospital deaths revealed 166 (82.6%) had documentation to suggest the patient was dying but this was performed late with a median time between documentation and death of 0.84 days. Furthermore, 132 (66%) patients received an intervention in the final 48 h of life. This highlights the need to improve the recognition and management of dying patients in acute hospitals.

End-of-life care in an Australian acute hospital: a retrospective observational study.

BACKGROUND: There is a gap in knowledge about the kind and quality of care experienced by hospital patients at the end of their lives. AIMS: To document and compare the patterns in end-of-life care for patients dying across a range of different medical units in an acute care hospital. METHODS: A retrospective observational study of consecutive adult inpatient deaths between 1 July 2010 and 30 June 2014 in four different medical units of an Australian tertiary referral hospital was performed. Units were selected on the basis of highest inpatient death rates and included medical oncology, respiratory medicine, cardiology and gastroenterology/hepatology. RESULTS: Overall, 41% of patients died with active medical treatment plans, but significantly more respiratory and cardiology patients died with ongoing treatment (46 and 75% respectively) than medical oncology and gastroenterology patients (each 27%, P < 0.05). More medical oncology and gastroenterology patients were recognised as dying (92 and 88%) compared with 72% of respiratory and only 38% of cardiology patients (P < 0.001). Significantly, more medical oncology patients were referred to palliative care and received comfort care plans than all other patient groups. However, the rate of non-palliative interventions given in the final 48 h was not significantly different between all four groups. CONCLUSIONS: There were differences in managing the dying process between all disciplines. A possible solution to these discrepancies would be to create an integrated palliative care approach across the hospital. Improving and reducing interdisciplinary practice variations will allow more patients to have a high-quality and safe death in acute hospitals.

A comparison of the opinions of intensive care unit staff and family members of the treatment intensity received by patients admitted to an intensive care unit: A multicentre survey.

BACKGROUND: Achieving shared decision-making in the intensive care unit (ICU) is challenging because of limited patient capacity, leading to a reliance on surrogate decision-makers. Prior research shows that ICU staff members often perceive that patients receive inappropriate or futile treatments while some surrogate decision-makers of patients admitted to the ICU report inadequate communication with physicians. Therefore, understanding the perceptions of both ICU staff and surrogate decision-makers around wishes for ICU treatments is an essential component to improve these situations. OBJECTIVES: The objectives of this study were to compare perceptions of ICU staff with surrogate decision-makers about the intensity and appropriateness of treatments received by patients and analyse the causes of any incongruence. METHODS: A multicentred, single-day survey of staff and surrogate decision-makers of ICU inpatients was conducted across four Australian ICUs in 2014. Patients were linked to a larger prospective observational study, allowing comparison of patient outcomes. RESULTS: Twelve of 32 patients were identified as having a mismatch between staff and surrogate decision-maker perceptions. For these 12 patients, all 12 surrogate decision-makers believed that the treatment intensity the patient was receiving was of the appropriate intensity and duration. Mismatched patients were more likely to be emergency admissions to ICU compared with nonmismatched patients (0.0% vs 42.1%, p = 0.012) and have longer ICU admissions (7.5 vs 3, p = 0.022). There were no significant differences in perceived communication (p = 0.61). CONCLUSIONS: Family members did not share the same perceptions of treatment with ICU staff. This may result from difficulty in prognostication; challenges in conveying poor prognoses to surrogate decision-makers; and the accuracy of surrogate decision-makers.

Mobilisation is feasible in intensive care patients receiving vasoactive therapy: An observational study.

BACKGROUND: Mobilisation of intensive care unit (ICU) patients reduces ICU-acquired weakness and is associated with better functional outcomes. However, the prevalence of mobilisation of ICU patients remains low. A known barrier to mobilisation is haemodynamic instability, frequently with patients requiring vasoactive therapy. There is a lack of published data to guide clinicians about the safety and feasibility of mobilising patients receiving vasoactive therapy. OBJECTIVES: To describe our mobilisation practice in ICU patients receiving vasoactive therapy and identify factors associated with mobilisation and adverse events. METHODS: Retrospective cohort study of patients undergoing vasoactive therapy in a 31-bed tertiary ICU (October-December, 2016). Details of vasoactive drug dosage, mobilisation, and adverse events were extracted from databases, including mobilisation intensity (ICU Mobility Scale [IMS]). Two generalised linear mixed models were used: first, to describe factors associated with mobilisation and second, to describe factors associated with adverse events during mobilisation, adjusting for age, gender, and acute physiology and chronic health evaluation II score as co-variates. RESULTS: In 119 patients undergoing vasoactive therapy on 371 cumulative vasoactive days, 195 mobilisation episodes occurred (37.5% of vasoactive days). Low (76.8%) and moderate (13.7%) dose vasoactive therapies were associated with a higher probability of mobilisation relative to high (9.4%) dose therapy (odds ratio = 5.50, 95% confidence interval = 2.23-13.59 and odds ratio = 2.50, 95% confidence interval = 0.95-6.59, respectively). For patients who mobilised on vasoactive therapy (n = 72), maximum mobilisation intensity was low (IMS = 1-2) in 31%, moderate (IMS = 3-5) in 51%, and high (IMS = 6-10) in 18% of vasoactive days. While no serious adverse events occurred, there were 14 occurrences of reversible hypotension requiring transient escalation of vasoactive therapy (7.3%), associated with lower mean arterial pressure (p = 0.001). CONCLUSION: In our ICU, patients mobilised on approximately one-third of vasoactive days. Clinicians should anticipate a higher risk of hypotension during mobilisation in patients receiving vasoactive therapy, which may require transient escalation of vasoactive therapy.

Women in Intensive Care study: a preliminary assessment of international data on female representation in the ICU physician workforce, leadership and academic positions.

BACKGROUND: Despite increasing female enrolment into medical schools, persistent gender gaps exist in the physician workforce. There are limited published data on female representation in the critical care medicine workforce. METHODS: To obtain a global perspective, societies (n = 84; 79,834 members (40,363 physicians, 39,471 non-physicians)) registered with the World Federation of Societies of Intensive and Critical Care Medicine were surveyed. Longitudinal data on female trainee and specialist positions between 2006-2017 were obtained from Australia and New Zealand. Data regarding leadership and academic faculty representation were also collected from national training bodies and other organisations of critical care medicine. RESULTS: Of the 84 societies, 23 had a registered membership of greater than 500 members. Responses were received from 27 societies (n = 55,996), mainly high-income countries, covering 70.1% of the membership. Amongst the physician workforce, the gender distribution was available from six (22%) participating societies-mean proportion of females 37 ± 11% (range 26-50%). Longitudinal data from Australia and New Zealand between 2006 and 2017 demonstrate rising proportions of female trainees and specialists. Female trainee and specialist numbers increased from 26 to 37% and from 13 to 22% respectively. Globally, female representation in leadership positions was presidencies of critical care organisations (0-41%), representation on critical care medicine boards and councils (8-50%) and faculty representation at symposia (7-34%). Significant gaps in knowledge exist: data from low and middle-income countries, the age distribution and the time taken to enter and complete training. CONCLUSIONS: Despite limited information globally, available data suggest that females are under-represented in training programmes, specialist positions, academic faculty and leadership roles in intensive care. There are significant gaps in data on female participation in the critical care workforce. Further data from intensive care organisations worldwide are required to understand the demographics, challenges and barriers to their professional progress.

Hypoglycemia and risk of death in critically ill patients.

BACKGROUND: Whether hypoglycemia leads to death in critically ill patients is unclear. METHODS: We examined the associations between moderate and severe hypoglycemia (blood glucose, 41 to 70 mg per deciliter [2.3 to 3.9 mmol per liter] and ≤40 mg per deciliter [2.2 mmol per liter], respectively) and death among 6026 critically ill patients in intensive care units (ICUs). Patients were randomly assigned to intensive or conventional glucose control. We used Cox regression analysis with adjustment for treatment assignment and for baseline and postrandomization covariates. RESULTS: Follow-up data were available for 6026 patients: 2714 (45.0%) had moderate hypoglycemia, 2237 of whom (82.4%) were in the intensive-control group (i.e., 74.2% of the 3013 patients in the group), and 223 patients (3.7%) had severe hypoglycemia, 208 of whom (93.3%) were in the intensive-control group (i.e., 6.9% of the patients in this group). Of the 3089 patients who did not have hypoglycemia, 726 (23.5%) died, as compared with 774 of the 2714 with moderate hypoglycemia (28.5%) and 79 of the 223 with severe hypoglycemia (35.4%). The adjusted hazard ratios for death among patients with moderate or severe hypoglycemia, as compared with those without hypoglycemia, were 1.41 (95% confidence interval [CI], 1.21 to 1.62; P<0.001) and 2.10 (95% CI, 1.59 to 2.77; P<0.001), respectively. The association with death was increased among patients who had moderate hypoglycemia on more than 1 day (>1 day vs. 1 day, P=0.01), those who died from distributive (vasodilated) shock (P<0.001), and those who had severe hypoglycemia in the absence of insulin treatment (hazard ratio, 3.84; 95% CI, 2.37 to 6.23; P<0.001). CONCLUSIONS: In critically ill patients, intensive glucose control leads to moderate and severe hypoglycemia, both of which are associated with an increased risk of death. The association exhibits a dose-response relationship and is strongest for death from distributive shock. However, these data cannot prove a causal relationship.

An economic evaluation of the Prioritising Responses Of Nurses To deteriorating patient Observations (PRONTO) clinical trial.

BACKGROUND: Early recognition and response to clinical deterioration reduce the frequency of in-hospital cardiac arrests, mortality, and unplanned intensive care unit (ICU) admissions. This study aimed to investigate the impact of the Prioritising Responses Of Nurses To deteriorating patient Observations (PRONTO) intervention on hospital costs and patient length of stay (LOS). METHOD: The PRONTO cluster randomised control trial was conducted to improve nurses' responses to patients with abnormal vital signs. Hospital data were collected pre-intervention (T0) at 6 months (T1) and 12 months (T2) post-intervention. The economic evaluation involved a cost-consequence analysis from the hospital's perspective. Generalised estimating equations were used to estimate the parameters for regression models of the difference in costs and LOS between study groups and time points. RESULTS: Hospital admission data for 6065 patients (intervention group, 3102; control group, 2963) were collected from four hospitals for T0, T1 and T2. The intervention cost was 69.61 A$ per admitted patient, including the additional intervention training for nurses and associated labour costs. The results showed cost savings and a shorter LOS in the intervention group between T0 - T1 and T0 - T2 (cost differences T0 - T1: -364 (95% CI -3,782; 3049) A$ and T0 - T2: -1,710 (95% CI -5,162; 1,742) A$; and LOS differences T0 - T1: -1.10 (95% CI -2.44; 0.24) days and T0 & T2: -2.18 (95% CI -3.53; -0.82) days). CONCLUSION: The results of the economic analysis demonstrated that the PRONTO intervention improved nurses' responses to patients with abnormal vital signs and significantly reduced hospital LOS by two days at 12 months in the intervention group compared to baseline. From the hospital's perspective, savings from reduced hospitalisations offset the costs of implementing PRONTO.

Systematic review and longitudinal analysis of implementing Artificial Intelligence to predict clinical deterioration in adult hospitals: what is known and what remains uncertain.

OBJECTIVE: To identify factors influencing implementation of machine learning algorithms (MLAs) that predict clinical deterioration in hospitalized adult patients and relate these to a validated implementation framework. MATERIALS AND METHODS: A systematic review of studies of implemented or trialed real-time clinical deterioration prediction MLAs was undertaken, which identified: how MLA implementation was measured; impact of MLAs on clinical processes and patient outcomes; and barriers, enablers and uncertainties within the implementation process. Review findings were then mapped to the SALIENT end-to-end implementation framework to identify the implementation stages at which these factors applied. RESULTS: Thirty-seven articles relating to 14 groups of MLAs were identified, each trialing or implementing a bespoke algorithm. One hundred and seven distinct implementation evaluation metrics were identified. Four groups reported decreased hospital mortality, 1 significantly. We identified 24 barriers, 40 enablers, and 14 uncertainties and mapped these to the 5 stages of the SALIENT implementation framework. DISCUSSION: Algorithm performance across implementation stages decreased between in silico and trial stages. Silent plus pilot trial inclusion was associated with decreased mortality, as was the use of logistic regression algorithms that used less than 39 variables. Mitigation of alert fatigue via alert suppression and threshold configuration was commonly employed across groups. CONCLUSIONS: : There is evidence that real-world implementation of clinical deterioration prediction MLAs may improve clinical outcomes. Various factors identified as influencing success or failure of implementation can be mapped to different stages of implementation, thereby providing useful and practical guidance for implementers.
