Formal Ethics Consultation in Extracorporeal Membrane Oxygenation Patients: A Single-Center Retrospective Cohort of a Quaternary Pediatric Hospital.

OBJECTIVE: To examine characteristics associated with formal ethics consultation (EC) referral in pediatric extracorporeal membrane oxygenation (ECMO) cases, and document ethical issues presented. DESIGN: Retrospective cohort study using mixed methods. SETTING: Single-center quaternary pediatric hospital. PATIENTS: Patients supported on ECMO (January 2012 to December 2021). INTERVENTIONS: We compared clinical variables among ECMO patients according to the presence of EC. We defined optimal cutoffs for EC based on run duration, ICU length of stay (LOS), and sum of procedures or complications. To identify independent explanatory variables for EC, we used a forward stepwise selection multivariable logistic regression model. EC records were thematically characterized into ethical issues. MEASUREMENTS AND MAIN RESULTS: Of 601 ECMO patients and 225 patients with EC in 10 years, 27 ECMO patients received EC (4.5% of ECMO patients, 12% of all ECs). On univariate analysis, use of EC vs. not was associated with multiple ECMO runs, more complications/procedures, longer ICU LOS and ECMO duration, cardiac admissions, decannulation outcome, and higher mortality. Cutoffs for EC were ICU LOS >52 days, run duration >160 hours, and >6 complications/procedures. Independent associations with EC included these three cutoffs and older age. The model showed good discrimination (area under the curve 0.88 [0.83, 0.93]) and fit. The most common primary ethical issues were related to end-of-life, ECMO discontinuation, and treatment decision-making. Moral distress was cited in 22 of 27 cases (82%). CONCLUSION: EC was used in 4.5% of our pediatric ECMO cases, with most ethical issues related to end-of-life care or ECMO discontinuation. Older age, longer ICU LOS, prolonged runs, and multiple procedures/complications were associated with greater odds for EC requests. These data highlight our single-center experience of ECMO-associated ethical dilemmas. Historical referral patterns may guide a supported decision-making framework. Future work will need to include quality improvement projects for timely EC, with evaluation of impacts on relevant endpoints.

Extracorporeal Life Support Organization Registry International Report 2022: 100,000 Survivors.

The Extracorporeal Life Support Organization (ELSO) maintains the world's largest extracorporeal membrane oxygenation (ECMO) registry by volume, center participation, and international scope. This 2022 ELSO Registry Report describes the program characteristics of ECMO centers, processes of ECMO care, and reported outcomes. Neonates (0-28 days), children (29 days-17 years), and adults (≥18 years) supported with ECMO from 2009 through 2022 and reported to the ELSO Registry were included. This report describes adjunctive therapies, support modes, treatments, complications, and survival outcomes. Data are presented descriptively as counts and percent or median and interquartile range (IQR) by year, group, or level. Missing values were excluded before calculating descriptive statistics. Complications are reported per 1,000 ECMO hours. From 2009 to 2022, 154,568 ECMO runs were entered into the ELSO Registry. Seven hundred and eighty centers submitted data during this time (557 in 2022). Since 2009, the median annual number of adult ECMO runs per center per year increased from 4 to 15, whereas for pediatric and neonatal runs, the rate decreased from 12 to 7. Over 50% of patients were transferred to the reporting ECMO center; 20% of these patients were transported with ECMO. The use of prone positioning before respiratory ECMO increased from 15% (2019) to 44% (2021) for adults during the coronavirus disease-2019 (COVID-19) pandemic. Survival to hospital discharge was greatest at 68.5% for neonatal respiratory support and lowest at 29.5% for ECPR delivered to adults. By 2022, the Registry had enrolled its 200,000th ECMO patient and 100,000th patient discharged alive. Since its inception, the ELSO Registry has helped centers measure and compare outcomes across its member centers and strategies of care. Continued growth and development of the Registry will aim to bolster its utility to patients and centers.

Trends in intravenous immunoglobulin use in New South Wales, Australia.

BACKGROUND: Intravenous immunoglobulin (IVIg) is a critical replacement therapy for immunodeficiencies and immunomodulatory treatment for autoimmune and inflammatory diseases. Adequate supply of IVIg is a global issue, necessitating supply restrictions. In Australia, despite strict criteria for use, demand for IVIg has increased over time and exceeds domestic supply. OBJECTIVE: Factors associated with the upward trend in overall IVIg use were examined, including in the number of unique patients, IVIg dosing and treatment frequency and variations by prescribing discipline and disease group. METHODS: De-identified data of IVIg dispensed in the largest Australian state (New South Wales) from 2007 to 2013 were provided by Australian Red Cross Lifeblood. Trends and projections were calculated using log-linear regression of unique patients, treatment episodes and grams of IVIg for overall use and use stratified by discipline and disease group. RESULTS: During the study period, 169 453 treatment episodes were recorded for 12 547 unique patients accounting for 5 827 787 g of IVIg use. Overall, IVIg use increased by 12.0% (11.5-12.6%) per year representing a 97.7% increase (91.6-104%) over the study period. The highest growth was among neurological conditions (16.0% (14.9-17.1%) per year). An increase in the number of unique patients was the primary driver of this growth, augmented by increases in the frequency and average dose per treatment. CONCLUSIONS: Clinically acceptable measures to improve management of IVIg supply are needed including optimising dose, frequency and duration of treatment. Formal evaluation of IVIg versus alternatives, including cost-effectiveness and comparative efficacy, is warranted.

Nutritional blindness from avoidant-restrictive food intake disorder - recommendations for the early diagnosis and multidisciplinary management of children at risk from restrictive eating.

Avoidant-restrictive food intake disorder (ARFID) is an eating disorder characterised by limited consumption or the avoidance of certain foods, leading to the persistent failure to meet the individual's nutritional and/or energy needs. The disordered eating is not explained by the lack of available food or cultural beliefs. ARFID is often associated with a heightened sensitivity to the sensory features of different types of food and may be more prevalent among children with autism spectrum disorder (ASD) for this reason. Sight loss from malnutrition is one of the most devastating and life-changing complications of ARFID, but difficult to diagnose in young children and those with ASD who have more difficulty with communicating their visual problems to carers and clinicians, leading to delayed treatment and greater probability of irreversible vision loss. In this article, we highlight the importance of diet and nutrition to vision and the diagnostic and therapeutic challenges that clinicians and families may face in looking after children with ARFID who are at risk of sight loss. We recommend a scaled multidisciplinary approach to the early identification, investigation, referral and management of children at risk of nutritional blindness from ARFID.

Higher Survival With the Use of Extracorporeal Cardiopulmonary Resuscitation Compared With Conventional Cardiopulmonary Resuscitation in Children Following Cardiac Surgery: Results of an Analysis of the Get With The Guidelines-Resuscitation Registry.

OBJECTIVES: Extracorporeal membrane oxygenation to support cardiopulmonary resuscitation (CPR) is increasingly used in children suffering cardiac arrest after cardiac surgery. However, its efficacy in promoting survival has not been evaluated. We compared survival of pediatric cardiac surgery patients suffering in-hospital cardiac arrest who were resuscitated with extracorporeal CPR (E-CPR) to those resuscitated with conventional CPR (C-CPR) using propensity matching. DESIGN: Retrospective study using multicenter data from the American Heart Association Get With The Guidelines-Resuscitation registry (2008-2020). SETTING: Multicenter cardiac arrest database containing cardiac arrest and CPR data from U.S. hospitals. PATIENTS: Cardiac surgical patients younger than 18 years old who suffered in-hospital cardiac arrest and received greater than or equal to 10 minutes of CPR. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among 1223 patients, 741 (60.6%) received C-CPR and 482 (39.4%) received E-CPR. E-CPR utilization increased over the study period ( p < 0.001). Duration of CPR was longer in E-CPR compared with C-CPR recipients (42 vs. 26 min; p < 0.001). In a propensity score matched cohort (382 E-CPR recipients, 382 C-CPR recipients), E-CPR recipients had survival to discharge (odds ratio [OR], 2.22; 95% CI, 1.7-2.9; p < 0.001). E-CPR survival was only higher when CPR duration was greater than 18 minutes. Propensity matched analysis using patients from institutions contributing at least one E-CPR case ( n = 35 centers; 353 E-CPR recipients, 353 C-CPR recipients) similarly demonstrated improved survival in E-CPR recipients compared with those who received C-CPR alone (OR, 2.08; 95% CI, 1.6-2.8; p < 0.001). CONCLUSIONS: E-CPR compared with C-CPR improved survival in children suffering cardiac arrest after cardiac surgery requiring CPR greater than or equal to 10 minutes.

Safety Analysis of Extended Platelet Shelf-Life with Large-Volume Delayed Sampling on BACT/ALERT® VIRTUO® in Australia.

Transfusion-transmitted bacterial infection (TTBI) is the leading cause of transfusion-transmitted infections. Platelet components are more likely to be associated with bacterial contamination due to their storage requirements. Australian Red Cross Lifeblood introduced the bacterial contamination screening (BCS) of all platelet components in 2008. The process was recently updated with the use of BACT/ALERT® VIRTUO®, a large-volume delayed sampling (LVDS) protocol and extending platelet shelf-life to seven days. This article describes the results from the routine BCS of platelet components in Australia. Use of VIRTUO has resulted in lower false-positive rates, reducing wastage and improving platelet inventory. Our findings show that the combination of LVDS and VIRTUO improves the safety of platelet transfusions through earlier time to detection, especially for pathogenic bacterial species. Pathogenic bacteria grew within 24 h of incubation with a clear delineation between pathogenic and non-pathogenic species. The data show this protocol is very safe, with no TTBI cases during this time. There were no TTBI reports in recipients of platelet components that subsequently had a positive culture with Cutibacterium species, probably due to the low pathogenic potential of these organisms and slow replication in aerobic platelet bags. We conclude there is no advantage in incubating culture bottles beyond five days.

Thrombotic and hemorrhagic complications of COVID-19 in adults hospitalized in high-income countries compared with those in adults hospitalized in low- and middle-income countries in an international registry.

Background: COVID-19 has been associated with a broad range of thromboembolic, ischemic, and hemorrhagic complications (coagulopathy complications). Most studies have focused on patients with severe disease from high-income countries (HICs). Objectives: The main aims were to compare the frequency of coagulopathy complications in developing countries (low- and middle-income countries [LMICs]) with those in HICs, delineate the frequency across a range of treatment levels, and determine associations with in-hospital mortality. Methods: Adult patients enrolled in an observational, multinational registry, the International Severe Acute Respiratory and Emerging Infections COVID-19 study, between January 1, 2020, and September 15, 2021, met inclusion criteria, including admission to a hospital for laboratory-confirmed, acute COVID-19 and data on complications and survival. The advanced-treatment cohort received care, such as admission to the intensive care unit, mechanical ventilation, or inotropes or vasopressors; the basic-treatment cohort did not receive any of these interventions. Results: The study population included 495,682 patients from 52 countries, with 63% from LMICs and 85% in the basic treatment cohort. The frequency of coagulopathy complications was higher in HICs (0.76%-3.4%) than in LMICs (0.09%-1.22%). Complications were more frequent in the advanced-treatment cohort than in the basic-treatment cohort. Coagulopathy complications were associated with increased in-hospital mortality (odds ratio, 1.58; 95% CI, 1.52-1.64). The increased mortality associated with these complications was higher in LMICs (58.5%) than in HICs (35.4%). After controlling for coagulopathy complications, treatment intensity, and multiple other factors, the mortality was higher among patients in LMICs than among patients in HICs (odds ratio, 1.45; 95% CI, 1.39-1.51). Conclusion: In a large, international registry of patients hospitalized for COVID-19, coagulopathy complications were more frequent in HICs than in LMICs (developing countries). Increased mortality associated with coagulopathy complications was of a greater magnitude among patients in LMICs. Additional research is needed regarding timely diagnosis of and intervention for coagulation derangements associated with COVID-19, particularly for limited-resource settings.

Cardiac arrest and cardiopulmonary resuscitation in pediatric patients with cardiac disease: a narrative review.

Children with cardiac disease are at a higher risk of cardiac arrest as compared to healthy children. Delivering adequate cardiopulmonary resuscitation (CPR) can be challenging due to anatomic characteristics, risk profiles, and physiologies. We aimed to review the physiological aspects of resuscitation in different cardiac physiologies, summarize the current recommendations, provide un update of current literature, and highlight knowledge gaps to guide research efforts. We specifically reviewed current knowledge on resuscitation strategies for high-risk categories of patients including patients with single-ventricle physiology, right-sided lesions, right ventricle restrictive physiology, left-sided lesions, myocarditis, cardiomyopathy, pulmonary arterial hypertension, and arrhythmias. Cardiac arrest occurs in about 1% of hospitalized children with cardiac disease, and in 5% of those admitted to an intensive care unit. Mortality after cardiac arrest in this population remains high, ranging from 30 to 65%. The neurologic outcome varies widely among studies, with a favorable neurologic outcome at discharge observed in 64%-95% of the survivors. Risk factors for cardiac arrest and associated mortality include younger age, lower weight, prematurity, genetic syndrome, single-ventricle physiology, arrhythmias, pulmonary arterial hypertension, comorbidities, mechanical ventilation preceding cardiac arrest, surgical complexity, higher vasoactive-inotropic score, and factors related to resources and institutional characteristics. Recent data suggest that Extracorporeal membrane oxygenation CPR (ECPR) may be a valid strategy in centers with expertise. Overall, knowledge on resuscitation strategies based on physiology remains limited, with a crucial need for further research in this field. Collaborative and interprofessional studies are highly needed to improve care and outcomes for this high-risk population. What is Known: • Children with cardiac disease are at high risk of cardiac arrest, and cardiopulmonary resuscitation may be challenging due to unique characteristics and different physiologies. • Mortality after cardiac arrest remains high and neurologic outcomes suboptimal. What is New: • We reviewed the unique resuscitation challenges, current knowledge, and recommendations for different cardiac physiologies. • We highlighted knowledge gaps to guide research efforts aimed to improve care and outcomes in this high-risk population.

Patterns of contraceptive use through later reproductive years: A cohort study of Australian women with chronic disease.

BACKGROUND: Pregnancies among women with chronic disease are associated with poor maternal and fetal outcomes. There is a need to understand how women use or don't use contraception across their reproductive years to better inform the development of preconception care strategies to reduce high risk unintended pregnancies, including among women of older reproductive age. However, there is a lack of high-quality longitudinal evidence to inform such strategies. We examined patterns of contraceptive use among a population-based cohort of reproductive aged women and investigated how chronic disease influenced contraceptive use over time. METHODS AND FINDINGS: Contraceptive patterns from 8,030 women of reproductive age from the Australian Longitudinal Study on Women's Health (1973-78 cohort), who were at potential risk of an unintended pregnancy were identified using latent transition analysis. Multinomial mixed-effect logistic regression models were used to evaluate the relationship between contraceptive combinations and chronic disease. Contraception non-use increased between 2006 and 2018 but was similar between women with and without chronic disease (13.6% vs. 12.7% among women aged 40-45 years in 2018). When specific contraceptive use patterns were examined over time, differences were found for women with autoinflammatory diseases only. These women had increased odds of using condom and natural methods (OR = 1.20, 95% CI = 1.00, 1.44), and sterilisation and other methods (OR = 1.61, 95% CI = 1.08, 2.39) or no contraception (OR = 1.32, 95% CI = 1.04, 1.66), compared to women without chronic disease using short-acting methods and condoms. CONCLUSION: Potential gaps in the provision of appropriate contraceptive access and care exist for women with chronic disease, particularly for women diagnosed with autoinflammatory conditions. Development of national guidelines as well as a clear coordinated contraceptive strategy that begins in adolescence and is regularly reviewed during care management through their main reproductive years and into perimenopause is required to increase support for, and agency among, women with chronic disease.

Foundations of a life support equipment exchange platform.

Background: The Extracorporeal Life Support Organization Supplies Platform (https://Supplies.ELSO.org) was created out of Extracorporeal Membrane Oxygenation (ECMO) disposable product shortage prior to and during the Coronavirus Disease 2019 (COVID-19) pandemic. This novel Platform supports Centers in obtaining disposables from other Centers when alternative avenues are exhausted. Methods: Driven by the opportunity for increased patient care by using the product availability of the 962 ELSO centers worldwide was the motivation to form an efficient online supply sharing Platform. The pandemic created by COVID-19 became a catalyst to further recognize the magnitude of the supply disruption on a global scale, impacting allocations and guidelines for institutions, practice, and patient care. Conclusions: Records kept on the Platform website are helpful to the industry by providing insights into where difficulties exist in the supply chain for needed equipment. Yet, the common thread is awareness, of how critical situations can stretch resources and challenge our resolve for the best patient care. ELSO is proud to support member centers in these situations, by providing a means of attaining needed ECMO life support products to cover supply shortages.

The Use of Extracorporeal Membrane Oxygenation for COVID-19: Lessons Learned.

The coronavirus disease 2019 (COVID-19) pandemic has seen an increase in global cases of severe acute respiratory distress syndrome (ARDS), with a concomitant increased demand for extracorporeal membrane oxygenation (ECMO). Outcomes of patients with severe ARDS due to COVID-19 infection receiving ECMO support are evolving. The need for surge capacity, practical and ethical limitations on implementing ECMO, and the prolonged duration of ECMO support in patients with COVID-19-related ARDS has revealed limitations in organization and resource utilization. Coordination of efforts at multiple levels, from research to implementation, resulted in numerous innovations in the delivery of ECMO.

Patterns of Labour Interventions and Associated Maternal Biopsychosocial Factors in Australia: a Path Analysis.

In Australia, nearly half of births involve labour interventions. Prior research in this area has relied on cross-sectional and administrative health data and has not considered biopsychosocial factors. The current study examined direct and indirect associations between biopsychosocial factors and labour interventions using 19 years of population-based prospective data. The study included singleton babies among primiparous women of the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health. Data from 5459 women who started labour were analysed using path analysis. 42.2% of babies were born without intervention (episiotomy, instrumental, or caesarean delivery): Thirty-seven percent reported vaginal birth with episiotomy and instrumental birth interventions, 18% reported an unplanned caesarean section without episiotomy and/or instrumental interventions, and 3% reported unplanned caesarean section after episiotomy and/or instrumental interventions. Vaginal births with episiotomy and/or instrumental interventions were more likely among women with chronic hypertension (RRR(95%-CI):1.50(1.12-2.01)), a perceived length of labour of more than 36 h (RRR(95%-CI):1.86(1.45-2.39)), private health insurance (RRR(95%-CI):1.61(1.41-1.85)) and induced labour (RRR(95%-CI):1.69(1.46-1.94)). Risk factors of unplanned caesarean section without episiotomy and/or instrumental birth intervention included being overweight (RRR(95%-CI):1.30(1.07-1.58)) or obese prepregnancy (RRR(95%-CI):1.63(1.28-2.08)), aged ≥ 35 years (RRR(95%-CI):1.87(1.46-2.41)), having short stature (< 154 cm) (RRR(95%-CI):1.68(1.16-2.42)), a perceived length of labour of more than 36 h (RRR(95%-CI):3.26(2.50-4.24)), private health insurance (RRR(95%-CI):1.38(1.17-1.64)), and induced labour (RRR(95%-CI):2.56(2.16-3.05)). Prevention and management of hypertension, diabetes, and obesity during preconception and/or antenatal care are keys for reducing labour interventions and strengthening the evidence-base around delivery of best practice obstetric care.

Extracorporeal Membrane Oxygenation Cannulation Timing in the Pediatric Myocarditis Population: An Exploratory Analysis From the Extracorporeal Life Support Organization Registry.

Children presenting with acute myocarditis may experience rapid clinical deterioration requiring extracorporeal membrane oxygenation (ECMO); however, our understanding of best practices and timing of ECMO initiation are lacking. We explored the relationships between pre-cannulation factors and survival in this high-acuity patient population. DESIGN: Retrospective review of a large international registry. Primary outcome was survival to hospital discharge, stratified by incident cardiac arrest (CA) prior to ECMO and time to cannulation after intubation. SETTING AND SUBJECTS: The Extracorporeal Life Support Organization registry was queried for patients less than or equal to 18 years old receiving ECMO support for myocarditis between 2007 and 2018. Exclusion criteria included being nonindex runs, non-venoarterial ECMO or missing data points for main variables studied. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Population characteristics and survival were compared using t test, Wilcoxon rank-sum test, or Fisher exact test. Multivariable logistic regression was used for significant factors in the unadjusted logistic regression. Among 506 index ECMO runs in pediatric patients with myocarditis, survival for the cohort was 72%, with no difference between early and late eras (2007-2012 vs 2013-2018; p = 0.69). Survivors demonstrated higher pre-ECMO pH levels as well as shorter intubation-to-cannulation (ITC) times (3 hr [interquartile range (IQR)], 1-14 hr vs 6 hr [IQR, 2-20 hr]; p = 0.021). CA occurred within 24 hours prior to ECMO cannulation, including extracorporeal cardiopulmonary resuscitation, in 54% of ECMO runs (n = 273). Accounting for the interaction between pre-ECMO CA occurrence and ITC time, longer ITC time remained associated with lower survival for patients who did not experience a CA prior to ECMO, with adjusted odds ratio of 0.09 (IQR, 0.02-0.40; p = 0.002) for ITC time greater than or equal to 18 hours. CONCLUSIONS: The results of this multicenter analysis of ECMO utilization and outcomes for pediatric myocarditis suggest that patients approaching ECMO cannulation who have not experienced CA may have better survival outcomes if cannulated onto ECMO early after intubation.
