Abstract
Race-conscious research identifies health disparities with 1) rigorous and responsible data collection, 2) intentionality and considered analyses, and 3) interpretation of results that advance health equity. Individual registries must overcome specific challenges to promote race-conscious research, and this paper describes ways to achieve this with a focus on the international Extracorporeal Life Support Organization (ELSO) registry. This article reviews ELSO registry publications that studied race with outcomes to consider whether research outputs align with race-conscious concepts and describe the direction of associations reported. Studies were identified via secondary analysis of a comprehensive scoping review on ECMO disparities. Of 32 multicenter publications, two (6%) studied race as the primary objective. Statistical analyses, confounder adjustment, and inclusive, antibiased language were inconsistently used. Only two (6%) papers explicitly discussed mechanistic drivers of inequity such as structural racism, and five (16%) discussed race variable limitations or acknowledged unmeasured confounders. Extracorporeal Life Support Organization registry publications demonstrated more adverse ECMO outcomes for underrepresented/minoritized populations than non-ELSO studies. With the objective to promote race-conscious ELSO registry research outputs, we provide a comprehensive understanding of race variable limitations, suggest reasoned retrospective analytic approaches, offer ways to interpret results that advance health equity, and recommend practice modifications for data collection.

Abstract
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.

Front Pediatr 2024; 12:1329648. [PMID: 38361997 PMCID: PMC10867174 DOI: 10.3389/fped.2024.1329648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 01/19/2024] [Indexed: 02/17/2024] Open
Abstract
Introduction The influence of social determinants of health (SDOH) on access to care and outcomes for critically ill children remains an understudied area with a paucity of high-quality data. Recent publications have highlighted the importance of incorporating SDOH considerations into research but the frequency with which this occurs in pediatric intensive care unit (PICU) research is unclear. Our objective was to determine the frequency and categories of SDOH variables reported and how these variables were defined in published PICU randomized controlled trials (RCTs). Methods We searched Medline, Embase, Lilacs, and Central from inception to Dec 2022. Inclusion criteria were randomized controlled trials of any intervention on children or their families in a PICU. Data related to study demographics and nine WHO SDOH categories were extracted, and descriptive statistics and qualitative data generated. Results 586 unique RCTs were included. Studies had a median sample size of 60 patients (IQR 40-106) with 73.0% of studies including ≤100 patients and 41.1% including ≤50 patients. A total of 181 (181/586, 30.9%) studies reported ≥1 SDOH variable of which 163 (163/586, 27.8%) reported them by randomization group. The most frequently reported categories were food insecurity (100/586, 17.1%) and social inclusion and non-discrimination (73/586, 12.5%). Twenty-five of 57 studies (43.9%) investigating feeding or nutrition and 11 of 82 (13.4%) assessing mechanical ventilation reported baseline nutritional assessments. Forty-one studies investigated interventions in children with asthma or bronchiolitis of which six reported on smoking in the home (6/41, 14.6%). Discussion Reporting of relevant SDOH variables occurs infrequently in PICU RCTs. In addition, when available, categorizations and definitions of SDOH vary considerably between studies. Standardization of SDOH variable collection along with consistent minimal reporting requirements for PICU RCT publications is needed.

"Death as the One Great Certainty": ethical implications of children with irreversible cardiorespiratory failure and dependence on extracorporeal membrane oxygenation. Front Pediatr 2024; 11:1325207.

Abstract
Introduction Advances in medical technology have led to both clinical and philosophical challenges in defining death. Highly publicized cases have occurred when families or communities challenge a determination of death by the irreversible cessation of neurologic function (brain death). Parallels can be drawn in cases where an irreversible cessation of cardiopulmonary function exists, in which cases patients are supported by extracorporeal cardiopulmonary support, such as extracorporeal membrane oxygenation (ECMO). Analysis Two cases and an ethical analysis are presented which compare and contrast contested neurologic determinations of death and refusal to accept the irreversibility of an imminent death by cardiopulmonary standards. Ambiguities in the Uniform Determination of Death Act are highlighted, as it can be clear, when supported by ECMO, that a patient could have suffered the irreversible cessation of cardiopulmonary function yet still be alive (e.g., responsive and interactive). Parallel challenges with communication with families around the limits of medical technology are discussed. Discussion Cases that lead to conflict around the removal of technology considered not clinically beneficial are likely to increase. Reframing our goals when death is inevitable is important for both families and the medical team. Building relationships and trust between all parties will help families and teams navigate these situations. All parties may require support for moral distress. Suggested approaches are discussed.

Abstract
OBJECTIVES A recent study from Germany found that survival after respiratory extracorporeal life support (ECLS) was lower among patients 10-20 years old than 20-30 years old. The objective of this study was to compare survival between teenage and young adult patients who receive respiratory ECLS. DESIGN Retrospective cohort study. SETTING Extracorporeal Life Support Organization registry, an international prospective quality improvement database. PATIENTS All patients ages 16-30 years cannulated for respiratory indications from 1990 to 2020 were included. Patients were divided into two groups, teens (16-19 yr old) and young adults (20-30 yr old). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Primary outcome was survival to discharge. Variables were considered for the multivariate logistic regression model if there was both a statistically significant difference (p ≤ 0.05) and a clinically meaningful absolute difference between the groups. A total of 5,751 patients were included, of whom 1,653 (29%) were teens and 4,098 (71%) were young adults. Survival to discharge was higher in young adults than teens, 69% versus 63% (p < 0.001). Severity of illness was higher among teens; however, survival within each stratum defined by Pao2/Fio2 ratio was higher in young adults than in teens. Use of venoarterial ECLS was higher in teens than in young adults, 15% versus 7%, respectively. Teens were more likely to receive high-frequency oscillatory ventilation and this therapy was associated with a longer time from admission to ECLS initiation. After adjusting for variables that differ significantly between the groups, the odds ratio for survival in young adults compared with teens was 1.14 (95% CI, 1.004-1.3). CONCLUSIONS In this large multicenter retrospective study, mortality was higher in teens than in young adults who received respiratory ECLS. This difference persisted after adjusting for multiple variables and the mechanism underlying these findings remains unclear.

Abstract
BACKGROUND Relationships between social drivers of health (SDoH) and pediatric health outcomes are highly complex with substantial inconsistencies in studies examining SDoH and extracorporeal membrane oxygenation (ECMO) outcomes. To add to this literature with emerging novel SDoH measures, and to address calls for institutional accountability, we examined associations between SDoH and pediatric ECMO outcomes. METHODS This single-center retrospective cohort study included children (<18 years) supported on ECMO (2012-2021). SDoH included Child Opportunity Index (COI), race, ethnicity, payer, interpreter requirement, urbanicity, and travel-time to hospital. COI is a multidimensional estimation of SDoH incorporating traditional (eg, income) and novel (eg, healthy food access) neighborhood attributes ([range 0-100] higher indicates healthier child development). Outcomes included in-hospital mortality, ECMO run duration, and length of stay (LOS). RESULTS 540 children on ECMO (96%) had a calculable COI. In-hospital mortality was 44% with median run duration of 125 hours and ICU LOS 29 days. Overall, 334 (62%) had cardiac disease, 92 (17%) neonatal respiratory failure, 93 (17%) pediatric respiratory failure, and 21 (4%) sepsis. Median COI was 64 (interquartile range 32-81), 323 (60%) had public insurance, 174 (34%) were from underrepresented racial groups, 57 (11%) required interpreters, 270 (54%) had urban residence, and median travel-time was 89 minutes. SDoH including COI were not statistically associated with outcomes in univariate or multivariate analysis. CONCLUSIONS We observed no significant difference in pediatric ECMO outcomes according to SDoH. Further research is warranted to better understand drivers of inequitable health outcomes in children, and potential protective mechanisms.

Abstract
BACKGROUND Despite the demonstrated benefits of rehabilitation, active physical therapy and early mobilization are not universally performed during critical illness, especially among patients receiving extracorporeal membrane oxygenation (ECMO), with variation among sites. OBJECTIVE What factors are predictive of physical mobility during venovenous (VV) ECMO support? METHODS We performed an observational analysis of an international cohort using data from the Extracorporeal Life Support Organization (ELSO) Registry. We analyzed adults (≥18 years) supported with VV ECMO who survived for at least 7 days. Our primary outcome was early mobilization (ICU Mobility Scale score >0) at day 7 of ECMO support. Hierarchical multivariable logistic regression models were utilized to identify factors independently associated with early mobilization at day 7 of ECMO. Results are reported as adjusted odds ratios (aOR) with 95% confidence intervals (95%CI). RESULTS Among 8,160 unique VV ECMO patients, factors independently associated with early mobilization included cannulation for transplantation (aOR 2.86 [95% CI 2.08-3.92]; p<0.001), avoidance of mechanical ventilation (aOR 0.51 [95% CI 0.41-0.64]; p<0.0001), higher center level patient volume (6-20 patients annually: aOR 1.49 [95% CI 1 to 2.23] and >20 patients annually: aOR 2 [95% CI: 1.37 to 2.93]; p<0.0001 for group), and cannulation with a dual-lumen cannula (aOR 1.25 [95% CI 1.08-1.42]; p = 0.0018). Early mobilization was associated with a lower probability of death (29 vs 48%; p<0.0001). CONCLUSIONS Higher levels of early mobilization on ECMO were associated modifiable and non-modifiable patient characteristics, including cannulation with a dual-lumen cannula, and with high center level patient volume.
