Relationship between the functional status scale and the pediatric overall performance category and pediatric cerebral performance category scales

Paediatric survivors of extracorporeal life support functional outcomes at one-year follow-up

OBJECTIVE

To investigate functional outcomes in children who survived extracorporeal life support at 12 months follow-up post-discharge.

BACKGROUND

Some patients who require extracorporeal life support acquire significant morbidity during their hospitalisation. The Functional Status Scale is a validated tool that allows quantification of paediatric function.

METHODS

A retrospective study that included children placed on extracorporeal life support at a quaternary children's hospital between March 2020 and October 2021 and had follow-up encounter within 12 months post-discharge.

RESULTS

Forty-two patients met inclusion criteria: 33% female, 93% veno-arterial extracorporeal membrane oxygenation (VA ECMO), and 12% with single ventricle anatomy. Median age was 1.7 years (interquartile range 10 days-11.9 years). Median hospital stay was 51 days (interquartile range 34-91 days), and median extracorporeal life support duration was 94 hours (interquartile range 56-142 hours). The median Functional Status Scale at discharge was 8.0 (interquartile range 6.3-8.8). The mean change in Functional Status Scale from discharge to follow-up at 9 months (n = 37) was -0.8 [95% confidence interval (CI) -1.3 to -0.4, p < 0.001] and at 12 months (n = 34) was -1 (95% confidence interval -1.5 to -0.4, p < 0.001); the most improvement was in the feeding score. New morbidity (Functional Status Scale increase of ≥3) occurred in 10 children (24%) from admission to discharge. Children with new morbidity were more likely to be younger (p = 0.01), have an underlying genetic syndrome (p = 0.02), and demonstrate evidence of neurologic injury by electroencephalogram or imaging (p = 0.05).

CONCLUSIONS

In survivors of extracorporeal life support, the Functional Status Scale improved from discharge to 12-month follow-up, with the most improvement demonstrated in the feeding score.

Association of Postarrest Hypotension Burden With Unfavorable Neurologic Outcome After Pediatric Cardiac Arrest

OBJECTIVE

Quantify hypotension burden using high-resolution continuous arterial blood pressure (ABP) data and determine its association with outcome after pediatric cardiac arrest.

DESIGN

Retrospective observational study.

SETTING

Academic PICU.

PATIENTS

Children 18 years old or younger admitted with in-of-hospital or out-of-hospital cardiac arrest who had invasive ABP monitoring during postcardiac arrest care.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

High-resolution continuous ABP was analyzed up to 24 hours after the return of circulation (ROC). Hypotension burden was the time-normalized integral area between mean arterial pressure (MAP) and fifth percentile MAP for age. The primary outcome was unfavorable neurologic status (pediatric cerebral performance category ≥ 3 with change from baseline) at hospital discharge. Mann-Whitney U tests compared hypotension burden, duration, and magnitude between favorable and unfavorable patients. Multivariable logistic regression determined the association of unfavorable outcomes with hypotension burden, duration, and magnitude at various percentile thresholds from the 5th through 50th percentile for age. Of 140 patients (median age 53 [interquartile range 11-146] mo, 61% male); 63% had unfavorable outcomes. Monitoring duration was 21 (7-24) hours. Using a MAP threshold at the fifth percentile for age, the median hypotension burden was 0.01 (0-0.11) mm Hg-hours per hour, greater for patients with unfavorable compared with favorable outcomes (0 [0-0.02] vs. 0.02 [0-0.27] mm Hg-hr per hour, p < 0.001). Hypotension duration and magnitude were greater for unfavorable compared with favorable patients (0.03 [0-0.77] vs. 0.71 [0-5.01]%, p = 0.003; and 0.16 [0-1.99] vs. 2 [0-4.02] mm Hg, p = 0.001). On logistic regression, a 1-point increase in hypotension burden below the fifth percentile for age (equivalent to 1 mm Hg-hr of burden per hour of recording) was associated with increased odds of unfavorable outcome (adjusted odds ratio [aOR] 14.8; 95% CI, 1.1-200; p = 0.040). At MAP thresholds of 10th-50th percentiles for age, MAP burden below the threshold was greater in unfavorable compared with favorable patients in a dose-dependent manner.

CONCLUSIONS

High-resolution continuous ABP data can be used to quantify hypotension burden after pediatric cardiac arrest. The burden, duration, and magnitude of hypotension are associated with unfavorable neurologic outcomes.

Long-term follow-up in pediatric intensive care-a narrative review

Pediatric intensive care is a rapidly developing medical specialty and with evolving understanding of pediatric pathophysiology and advances in technology, most children in the developed world are now surviving to intensive care and hospital discharge. As mortality rates for children with critical illness continue to improve, increasing PICU survivorship is resulting in significant long-term consequences of intensive care in these vulnerable patients. Although impairments in physical, psychosocial and cognitive function are well documented in the literature and the importance of establishing follow-up programs is acknowledged, no standardized or evidence-based approach to long-term follow-up in the PICU exists. This narrative review explores pediatric post-intensive care syndrome and summarizes the multifactorial deficits and morbidity that can occur in these patients following recovery from critical illness and subsequent discharge from hospital. Current practices around long-term follow-up are explored with discussion focusing on gaps in research and understanding with suggested ways forward and future directions.

Long-term outcomes after paediatric sepsis: A narrative review

OBJECTIVES

Sepsis is one of the leading causes of mortality in the paediatric population. However, knowledge is limited around morbidity in childhood sepsis survivors. The aim of this review is to identify and critically appraise the evidence for long-term outcomes in paediatric survivors of sepsis using the Post Intensive Care Syndrome - paediatrics (PICS-p) framework.

METHODS

A search for studies was undertaken in the electronic databases PubMed and Cumulative Index to Nursing and Allied Health Literature from 2010. Criteria for inclusion are as follows: participants >28 d adjusted age, diagnosed with sepsis, and follow-up after hospital discharge using a validated outcome measure. The PICS-p subdomains (cognitive, physical, emotional, and social) guided thematic synthesis of current literature. Study quality was assessed using the Newcastle-Ottawa Scale.

RESULTS

In total, nine studies, involving 2136 children, using 13 different outcome measures were included in the review. Mean follow-up time was 28 d after hospital discharge with a range of 7 d to 12 m across the PICS-p domains. Physical functioning was the most examined domain explored in six studies that used four outcome measures. Morbidity in physical, cognitive, and emotional domains was still evident at 9-12 m. No literature identified explored social health.

CONCLUSION(S)

Overall, we identified a wide range of measures, administered at various time points in studies of sepsis survivorship in childhood. Variation in follow-up timepoints, validated tools, and restricted outcome measures highlighted the lack in understanding of this priority area. Furthermore, long-term outcome research and a cohesive understanding across all the PICS-p domains are needed to better understand this population.

Short-Term Outcomes, Functional Status, and Risk Factors for Requiring Extracorporeal Life Support After Norwood Operation: A Single-Center Retrospective Study

Patients requiring extracorporeal life support (ECLS) post-Norwood operation constitute an extremely high-risk group. We retrospectively described short-term outcomes, functional status, and assessed risk factors for requiring ECLS post-Norwood operation between January 2010 and December 2020 in a high-volume center. During the study period, 269 patients underwent a Norwood procedure of which 65 (24%) required ECLS. Of the 65 patients, 27 (41.5%) survived to hospital discharge. Mean functional status scale (FSS) score at discharge increased from 6.0 on admission to 8.48 (p < 0.0001). This change was primary in feeding (p < 0.0001) and respiratory domains (p = 0.017). Seven survivors (26%) developed new morbidity, and two (7%) developed unfavorable functional outcomes. In the regression analysis, we showed that patients with moderate-severe univentricular dysfunction on pre-Norwood transthoracic echocardiogram (odds ratio [OR] = 6.97), modified Blalock Taussig Thomas (m-BTT) shunt as source of pulmonary blood flow (OR = 2.65), moderate-severe atrioventricular valve regurgitation on transesophageal echocardiogram (OR = 8.50), longer cardiopulmonary bypass time (OR = 1.16), longer circulatory arrest time (OR = 1.20), and delayed sternal closure (OR = 3.86), had higher odds of requiring ECLS (p < 0.05). Careful identification of these risk factors is imperative to improve the care of this high-risk cohort and improve overall outcomes.

Cognitive, Functional, and Quality of Life Outcomes 6 Months After Mechanical Ventilation for Bronchiolitis: A Secondary Analysis of Data From the Randomized Evaluation of Sedation Titration for Respiratory Failure Trial ( RESTORE )

OBJECTIVES

To describe rates and associated risk factors for functional decline 6 months after critical bronchiolitis in a large, multicenter dataset.

DESIGN

Nonprespecified secondary analysis of existing 6-month follow-up data of patients in the Randomized Evaluation of Sedation Titration for Respiratory Failure trial ( RESTORE , NCT00814099).

SETTING

Patients recruited to RESTORE in any of 31 PICUs in the United States, 2009-2013.

PATIENTS

Mechanically ventilated PICU patients under 2 years at admission with a primary diagnosis of bronchiolitis.

INTERVENTIONS

There were no interventions in this secondary analysis; in the RESTORE trial, PICUs were randomized to protocolized sedation versus usual care.

MEASUREMENTS AND MAIN RESULTS

"Functional decline," defined as worsened Pediatric Overall Performance Category and/or Pediatric Cerebral Performance Category (PCPC) scores at 6 months post-PICU discharge as compared with preillness baseline. Quality of life was assessed using Infant Toddler Quality of Life Questionnaire (ITQOL; children < 2 yr old at follow-up) or Pediatric Quality of Life Inventory (PedsQL) at 6 months post-PICU discharge. In a cohort of 232 bronchiolitis patients, 28 (12%) had functional decline 6 months postdischarge, which was associated with unfavorable quality of life in several ITQOL and PedsQL domains. Among 209 patients with normal baseline functional status, 19 (9%) had functional decline. In a multivariable model including all subjects, decline was associated with greater odds of worse baseline PCPC score and longer PICU length of stay (LOS). In patients with normal baseline status, decline was also associated with greater odds of longer PICU LOS.

CONCLUSIONS

In a random sampling of RESTORE subjects, 12% of bronchiolitis patients had functional decline at 6 months. Given the high volume of mechanically ventilated patients with bronchiolitis, this observation suggests many young children may be at risk of new morbidities after PICU admission, including functional and/or cognitive morbidity and reduced quality of life.

Mortality and Timing of Withdrawal of Life-Sustaining Therapies After Out-of-Hospital Cardiac Arrest: Two-Center Retrospective Pediatric Cohort Study

OBJECTIVES

Pediatric out-of-hospital cardiac arrest (OHCA) is associated with substantial morbidity and mortality. Limited data exist to guide timing and method of neurologic prognostication after pediatric OHCA, making counseling on withdrawal of life-sustaining therapies (WLSTs) challenging. This study investigates the timing and mode of death after pediatric OHCA and factors associated with mortality. Additionally, this study explores delayed recovery after comatose examination on day 3 postarrest.

DESIGN

This is a retrospective, observational study based on data collected from hospital databases and chart reviews.

SETTING

Data collection occurred in two pediatric academic hospitals between January 1, 2016, and December 31, 2020.

PATIENTS

Patients were identified from available databases and electronic medical record queries for the International Classification of Diseases , 10th Edition (ICD-10) code I46.9 (Cardiac Arrest). Patient inclusion criteria included age range greater than or equal to 48 hours to less than 18 years, OHCA within 24 hours of admission, greater than or equal to 1 min of cardiopulmonary resuscitation, and return-of-spontaneous circulation for greater than or equal to 20 min.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One hundred thirty-five children (65% male) with a median age of 3 years (interquartile range 0.6-11.8) met inclusion criteria. Overall, 63 of 135 patients (47%) died before hospital discharge, including 34 of 63 patients (54%) after WLST. Among these, 20 of 34 patients underwent WLST less than or equal to 3 days postarrest, including 10 of 34 patients who underwent WLST within 1 day. WLST occurred because of poor perceived neurologic prognosis in all cases, although 7 of 34 also had poor perceived systemic prognosis. Delayed neurologic recovery from coma on day 3 postarrest was observed in 7 of 72 children (10%) who ultimately survived to discharge.

CONCLUSIONS

In our two centers between 2016 and 2020, more than half the deaths after pediatric OHCA occurred after WLST, and a majority of WLST occurred within 3 days postarrest. Additional research is warranted to determine optimal timing and predictors of neurologic prognosis after pediatric OHCA to better inform families during goals of care discussions.

Fluid assessment, fluid balance, and fluid overload in sick children: a report from the Pediatric Acute Disease Quality Initiative (ADQI) conference

BACKGROUND

The impact of disorders of fluid balance, including the pathologic state of fluid overload in sick children has become increasingly apparent. With this understanding, there has been a shift from application of absolute thresholds of fluid accumulation to an appreciation of the intricacies of fluid balance, including the impact of timing, trajectory, and disease pathophysiology.

METHODS

The 26th Acute Disease Quality Initiative was the first to be exclusively dedicated to pediatric and neonatal acute kidney injury (pADQI). As part of the consensus panel, a multidisciplinary working group dedicated to fluid balance, fluid accumulation, and fluid overload was created. Through a search, review, and appraisal of the literature, summative consensus statements, along with identification of knowledge gaps and recommendations for clinical practice and research were developed.

CONCLUSIONS

The 26th pADQI conference proposed harmonized terminology for fluid balance and for describing a pathologic state of fluid overload for clinical practice and research. Recommendations include that the terms daily fluid balance, cumulative fluid balance, and percent cumulative fluid balance be utilized to describe the fluid status of sick children. The term fluid overload is to be preserved for describing a pathologic state of positive fluid balance associated with adverse events. Several recommendations for research were proposed including focused validation of the definition of fluid balance, fluid overload, and proposed methodologic approaches and endpoints for clinical trials.

The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Resuscitation With Vitamin C, Hydrocortisone, and Thiamin in Children With Septic Shock: A Multicenter Randomized Pilot Study

OBJECTIVES

Adjunctive therapy with vitamin C, hydrocortisone, and thiamin has been evaluated in adults, but randomized controlled trial (RCT) data in children are lacking. We aimed to test the feasibility of vitamin C, hydrocortisone, and thiamin in PICU patients with septic shock; and to explore whether the intervention is associated with increased survival free of organ dysfunction.

DESIGN

Open-label parallel, pilot RCT multicenter study. The primary endpoint was feasibility. Clinical endpoints included survival free of organ dysfunction censored at 28 days and nine secondary outcomes, shock reversal, and two proxy measures of intervention efficacy.

SETTING

Six PICUs in Australia and New Zealand.

PATIENTS

Children of age between 28 days and 18 years requiring vasoactive drugs for septic shock between August 2019 and March 2021.

INTERVENTIONS

Patients were assigned 1:1 to receive 1 mg/kg hydrocortisone every 6 hours (q6h), 30 mg/kg ascorbic acid q6h, and 4 mg/kg thiamin every 12 hours (n = 27), or standard septic shock management (n = 33).

MEASUREMENTS AND MAIN RESULTS

Sixty of 77 (78%) eligible patients consented with 91% of approached parents providing consent. The median time from randomization to intervention was 44 (interquartile range [IQR] 29-120) min. Seventy of seventy-seven (28%) patients had received IV steroids before randomization. Median survival alive and free of organ dysfunction was 20.0 (0.0-26.0) days in the intervention and 21.0 (0.0-25.0) days in the standard care group. Median PICU length of stay was 5.3 (2.5-11.3) days in the intervention group versus 6.9 (3.0-11.5) days in the control group. Shock reversal occurred at a median of 35.2 (14.6-101.2) hours in the intervention group versus 47.3 (22.4-106.8) hours in the standard care group (median difference -12 hr; 95% CI, -56.8 to 32.7 hr).

CONCLUSIONS

In children requiring vasopressors for septic shock, a protocol comparing adjunctive treatment with high-dose vitamin C, hydrocortisone, and thiamin versus standard care was feasible. These findings assist in making modifications to the trial protocol to enable a better-designed larger RCT.

Resuscitation With Early Adrenaline Infusion for Children With Septic Shock: A Randomized Pilot Trial

OBJECTIVES

In children with septic shock, guidelines recommend resuscitation with 40-60 mL/kg of fluid boluses, yet there is a lack of evidence to support this practice. We aimed to determine the feasibility of a randomized trial comparing early adrenaline infusion with standard fluid resuscitation in children with septic shock.

DESIGN

Open-label parallel randomized controlled, multicenter pilot study. The primary end point was feasibility; the exploratory clinical endpoint was survival free of organ dysfunction by 28 days.

SETTING

Four pediatric Emergency Departments in Queensland, Australia.

PATIENTS

Children between 28 days and 18 years old with septic shock.

INTERVENTIONS

Patients were assigned 1:1 to receive a continuous adrenaline infusion after 20 mL/kg fluid bolus resuscitation (n = 17), or standard care fluid resuscitation defined as delivery of 40 to 60 mL/kg fluid bolus resuscitation prior to inotrope commencement (n = 23).

MEASUREMENTS AND MAIN RESULTS

Forty of 58 eligible patients (69%) were consented with a median age of 3.7 years (interquartile range [IQR], 0.9-12.1 yr). The median time from randomization to inotropes was 16 minutes (IQR, 12-26 min) in the intervention group, and 49 minutes (IQR, 29-63 min) in the standard care group. The median amount of fluid delivered during the first 24 hours was 0 mL/kg (IQR, 0-10.0 mL/kg) in the intervention group, and 20.0 mL/kg (14.6-28.6 mL/kg) in the standard group (difference, -20.0; 95% CI, -28.0 to -12.0). The number of days alive and free of organ dysfunction did not differ between the intervention and standard care groups, with a median of 27 days (IQR, 26-27 d) versus 26 days (IQR, 25-27 d). There were no adverse events reported associated with the intervention.

CONCLUSIONS

In children with septic shock, a protocol comparing early administration of adrenaline versus standard care achieved separation between the study arms in relation to inotrope and fluid bolus use.

Chest compressions for pediatric organized rhythms: A hemodynamic and outcomes analysis

AIM

Pediatric cardiopulmonary resuscitation (CPR) guidelines recommend starting CPR for heart rates (HRs) less than 60 beats per minute (bpm) with poor perfusion. Objectives were to (1) compare HRs and arterial blood pressures (BPs) prior to CPR among patients with clinician-reported bradycardia with poor perfusion ("BRADY") vs. pulseless electrical activity (PEA); and (2) determine if hemodynamics prior to CPR are associated with outcomes.

METHODS AND RESULTS

Prospective observational cohort study performed as a secondary analysis of the ICU-RESUScitation trial (NCT028374497). Comparisons occurred (1) during the 15 seconds "immediately" prior to CPR and (2) over the two minutes prior to CPR, stratified by age (≤1 year, >1 year). Poisson regression models assessed associations between hemodynamics and outcomes. Primary outcome was return of spontaneous circulation (ROSC). Pre-CPR HRs were lower in BRADY vs. PEA (≤1 year: 63.8 [46.5, 87.0] min-1 vs. 120 [93.2, 150.0], p < 0.001; >1 year: 67.4 [54.5, 87.0] min-1 vs. 100 [66.7, 120], p < 0.014). Pre-CPR pulse pressure was higher among BRADY vs. PEA (≤1 year (12.9 [9.0, 28.5] mmHg vs. 10.4 [6.1, 13.4] mmHg, p > 0.001). Pre-CPR pulse pressure ≥ 20 mmHg was associated with higher rates of ROSC among PEA (aRR 1.58 [CI95 1.07, 2.35], p = 0.022) and survival to hospital discharge with favorable neurologic outcome in both groups (BRADY: aRR 1.28 [CI95 1.01, 1.62], p = 0.040; PEA: aRR 1.94 [CI95 1.19, 3.16], p = 0.008). Pre-CPR HR ≥ 60 bpm was not associated with outcomes.

CONCLUSIONS

Pulse pressure and HR are used clinically to differentiate BRADY from PEA. A pre-CPR pulse pressure >20 mmHg was associated with improved patient outcomes.

Trends in community response and long-term outcomes from pediatric cardiac arrest: A retrospective observational study

AIM

This study aimed to investigate trends over time in pre-hospital factors for pediatric out-of-hospital cardiac arrest (pOHCA) and long-term neurological and neuropsychological outcomes. These have not been described before in large populations.

METHODS

Non-traumatic arrest patients, 1 day-17 years old, presented to the Sophia Children's Hospital from January 2002 to December 2020, were eligible for inclusion. Favorable neurological outcome was defined as Pediatric Cerebral Performance Categories (PCPC) 1-2 or no difference with pre-arrest baseline. The trend over time was tested with multivariable logistic and linear regression models with year of event as independent variable.

FINDINGS

Over a nineteen-year study period, the annual rate of long-term favorable neurological outcome, assessed at a median 2.5 years follow-up, increased significantly (OR 1.10, 95%-CI 1.03-1.19), adjusted for confounders. Concurrently, annual automated external defibrillator (AED) use and, among adolescents, initial shockable rhythm increased significantly (OR 1.21, 95% CI 1.10-1.33 and OR 1.15, 95% CI 1.02-1.29, respectively), adjusted for confounders. For generalizability purposes, only the total intelligence quotient (IQ) was considered for trend analysis of all tested domains. Total IQ scores and bystander basic life support (BLS) rate did not change significantly over time.

INTERPRETATION

Long-term favorable neurological outcome, assessed at a median 2.5 years follow-up, improved significantly over the study period. Total IQ scores did not significantly change over time. Furthermore, AED use (OR 1.21, 95%CI 1.10-1.33) and shockable rhythms among adolescents (OR1.15, 95%CI 1.02-1.29) increased over time.

Validation of a Clinical Tool to Predict Neurological Outcomes in Critically Ill Children-A Prospective Observational Study

OBJECTIVES

To evaluate the performance of the empiric tool by Gupta et al. in predicting neurological outcomes in children admitted to the pediatric intensive care unit (PICU) and to evaluate the association of biomarkers S100B and NSE with neurological outcomes.

METHODS

This prospective observational study was conducted in 163 critically ill children aged 2 mo to 17 y admitted to the PICU from June 2020 to July 2021. The authors used the prediction tool developed by Gupta et al.; the tool was applied at admission and at PICU discharge/death. Samples for NSE and S100B were collected at admission and discharge. The performance of the new tool was assessed through discrimination and calibration. Risk factors for "unfavorable outcomes" (decline in PCPC score by > 1) were evaluated by multivariate analysis.

RESULTS

The PICU mortality was 28% (n = 45). When the tool developed by Gupta et al. was used at the time of admission, favorable neurological outcomes were predicted for 69% (112) children. The area under the curve for the new tool at admission was 0.72 and at discharge/death it was 0.99, and the calibration was excellent at both time points. Independent factors associated with unfavorable neurological outcomes were higher PCPC scores and organ failure. As the number of samples processed for NSE and S100B was less, statistical analysis was not attempted.

CONCLUSIONS

The new tool by Gupta et al. has good discrimination, calibration, sensitivity, and specificity and can be used as a prediction tool. NSE and S100B are promising biomarkers and need further evaluation.

Withholding life support for children with severe neurological impairment: Prevalence and predictive factors prior to admission in the PICU

BACKGROUND

Our study aimed to evaluate the prevalence and predictive factors of withholding life support for children suffering from severe neurological impairment before admission to the pediatric intensive care unit (PICU).

METHOD

Children under 18 years of age with severe neurological impairment, who were hospitalized between January 2006 and December 2016, were included in this retrospective study. They were allocated to a withholding group or a control group, depending on whether life support was withheld or not, before admission to the PICU.

RESULTS

Overall, 119 patients were included. At admission to the PICU, the rate of withholding life support was 10 % (n = 12). Predictive factors were: (1) a previous stay in the PICU (n = 11; 92 %, p<0.01, odds ratio [OR]: 14 [2-635], p = 0.001); (2) the need for respiratory support (n = 5; 42 %, p = 0.01, OR: 6 [1-27], p = 0.01); (3) the need for feeding support (n = 10; 83 %, p = 0.01, OR: 10 [2-100], p = 0.001); and (4) a higher functional status score (FSS: 16 [12.5-19] vs. 10 [8-13], p<0.01).

CONCLUSION

The withholding of life support for children suffering from severe neurological impairment appeared limited in our pediatric department. The main predictor was at least one admission to the PICU, which raised the question of the pediatrician's role in the decision to withhold life support.

Increased rates of invasive bacterial disease in late 2022

Invasive bacterial disease is associated with significant morbidity and mortality. In winter 2022, there was an apparent increased rate of invasive bacterial disease compared to preceding years. Cross-site retrospective analysis of the three Children's Health Ireland (CHI) hospitals looking at children admitted between 1st October 2022-31st December 2022 (Q4) with community-acquired invasive bacterial disease, defined as an abscess in a normally sterile site in the head, neck and chest or isolation or PCR detection of Streptococcus pneumoniae, Neisseria meningitidis, Streptococcus pyogenes (Group A streptococcus) or Haemophilus influenzae from a normally sterile site. Case numbers were compared to Q4 in each of 2018-2021. Eighty-two children met the case definition in Q4 2022 vs 97 (Q4 2018-2021). In 2022, 42/82 (51%) were female, median age 3.75 years (1.5-8.25 years). Only 2 (2%) were immunosuppressed and 2 others (2%) had underlying neurodisability. Fifty (61%) were admitted on second or subsequent presentation to a healthcare setting. Fifty-six (68%) had an abscess in a sterile site. Bloodstream infection (positive blood culture or PCR: 24 (29%)) was the most common site of infection, followed by neck 22 (27%) and intracranial 12 (15%). Group A streptococcus (GAS) 27 (33%) was the most common organism isolated. Seven cases (9%) died in 2022 compared to 2 patients (2%) from 2018 to 2021 (p < 0.05). More children had Paediatric Overall Performance Category (POPC) scores > 1 in 2022 than 2018-2021 (p = 0.003).  Conclusion: Invasive bacterial diseases increased in Q4 2022 with higher morbidity and mortality than in the preceding 4 years. Group A streptococcal infection was the most significant organism in 2022. What is known: • Invasive bacterial disease is the leading cause of childhood mortality globally. • There was an increase in cases of invasive Group A streptococcus infections reported in many countries (including Ireland) during the winter of 2022/23. What is new: • Head, neck and chest abscesses increased in Q4 of 2022 compared to the previous 4 years combined. • Invasive bacterial infections in Q4 of 2022 were associated with higher rates of mortality (9%), paediatric intensive care unit (PICU) admission (24%) and requirement for surgical drainage or intervention (67%) than in the preceding years.

Pediatric Intensive Care Unit Early Mobility Program: Impact on Patient Functional Status

INTRODUCTION

Patients admitted to the pediatric Intensive Care Unit (PICU) are frequently sedated, restrained, and placed on bed rest. These practices have known negative impacts including prolonged hospital stay and diminished functional status after discharge. The authors' objective was to investigate the impact of a PICU early mobility protocol on the frequency of orders for physical, occupational, and speech therapy (PT, OT, ST) and improvement in patient functional status.

METHODS

Patients admitted in 2019 prior to the development of the PICU early mobility protocol were compared to those admitted in 2020 who underwent the protocol. Differences in clinical characteristics; PICU length of stay; rates of PT, OT, and ST orders; rates of bedside mobility activities; and functional status scores (FSSs) were assessed in bivariate and multivariate analyses. The protocol included early PT, OT, and ST order placement and frequent in-room mobility activities.

RESULTS

Of the 384 patients included in the study, 216 (56%) were preprotocol patients, and 168 (44%) underwent the protocol. Patients in 2020 were more likely to receive a physical therapy order compared to their 2019 counterparts (79% vs 47%, p < 0.001). Patients in 2020 had a higher daily incidence of mobility activities compared to those in 2019 (4.88 activities vs 4.1 activities, p < 0.001). Changes in functional status scores were similar between the 2 groups.

CONCLUSION

PICU early mobility was associated with increased physical, occupational, and speech therapy orders and daily mobility activities but was not associated with a reduction in functional morbidity at discharge or 3 months post-discharge.

Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Early Functional Status Change After Cardiopulmonary Resuscitation in a Pediatric Heart Center: A Single-Center Retrospective Study

Children with cardiac disease are at significantly higher risk for in-hospital cardiac arrest (CA) compared with those admitted without cardiac disease. CA occurs in 2-6% of patients admitted to a pediatric intensive care unit (ICU) and 4-6% of children admitted to the pediatric cardiac-ICU. Treatment of in-hospital CA with cardiopulmonary resuscitation (CPR) results in return of spontaneous circulation in 43-64% of patients and survival rate that varies from 20 to 51%. We aimed to investigate the change in functional status of survivors who experienced an in-hospital CA using the functional status scale (FSS) in our heart center by conducting a retrospective study of all patients 0-18 years who experienced CA between June 2015 and December 2020 in a free-standing university-affiliated quaternary children's hospital. Of the 165 CA patients, 61% (n = 100) survived to hospital discharge. The non-survivors had longer length from admission to CA, higher serum lactate levels peri-CA, and received higher number of epinephrine doses. Using FSS, of the survivors, 26% developed new morbidity, and 9% developed unfavorable outcomes. There was an association of unfavorable outcomes with longer CICU-LOS and number of epinephrine doses given. Sixty-one-percent of CA patients survived to hospital discharge. Of the survivors, 26% developed new morbidity and 91% had favorable outcomes. Future multicenter studies are needed to help better identify modifiable risk factors for development of poor outcomes and help improve outcomes of this fragile patient population.

First documented rhythm and clinical outcome in children who undergo extracorporeal cardiopulmonary resuscitation for in-hospital cardiac arrest: A report from the american heart association get with the guidelines® - resuscitation registry (GWTG-R)

INTRODUCTION

Outcomes of conventional cardiopulmonary resuscitation are improved when the initial rhythm is shockable (ventricular fibrillation or pulseless ventricular tachycardia). In children, the first documented rhythm is typically asystole or pulseless electrical activity. We evaluate the role the initial rhythm plays in outcomes for children undergoing extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital cardiac arrest.

METHODS

Consecutive patients < 18 years with in-hospital ECPR events ≥ 10 minutes reported to the American Heart Association Get With The Guidelines® - Resuscitation registry from 2014 to 2019 were included. Primary outcome was survival to hospital discharge. Logistic regression modeling was used to compute propensity score matching based on patient, cardiac arrest event and hospital characteristics; patients with initial shockable rhythm were matched to patients with initial non-shockable rhythm.

RESULTS

The final cohort included 466 patients, of which 82 (18%) had a shockable, and 384 (82%) had a non-shockable initial rhythm. After propensity score matching of 287 (62%) patients, there was no difference in survival to hospital discharge (risk ratio [RR] 1.2, 95% CI, 0.95-1.53, p = 0.13) or favorable neurologic outcome, defined as Pediatric Cerebral Performance Category (PCPC) of 1 or 2, or no decline from baseline (RR 1.28, 95% CI, 0.84-1.96, p = 0.25) between patients with and without shockable initial rhythm.

CONCLUSIONS

In children with in-hospital cardiac arrest undergoing ECPR, there was no significant difference in survival or favorable neurologic outcome between those with initial shockable rhythm compared to non-shockable rhythm. Further investigation to evaluate ECPR patient characteristics and outcomes is warranted to help guide eligibility and ECMO deployment practices.

Outcomes of children with life-threatening status asthmaticus requiring isoflurane therapy and extracorporeal life support

BACKGROUND

Severe, refractory asthma is a life-threatening emergency that may be treated with isoflurane and extracorporeal life support. The objective of this study was to describe the clinical response to isoflurane and outcomes after discharge of children who received isoflurane and/or extracorporeal life-support for near-fatal asthma.

METHODS

This was a retrospective descriptive study using electronic medical record data from two pediatric intensive care units within a single healthcare system in Atlanta, GA.

RESULTS

Forty-five children received isoflurane, and 14 children received extracorporeal life support, 9 without a trial of isoflurane. Hypercarbia and acidosis improved within four hours of starting isoflurane. Four children died during the index admission for asthma. Twenty-seven percent had a change in Functional Status Score of three or more points from baseline to PICU discharge. Patients had median percent predicted FEV1 and FEV1/FVC ratios pre- and post-bronchodilator values below normal pediatric values.

CONCLUSION

Children who received isoflurane and/or ECLS had a high frequency of previous PICU admission and intubation. Improvement in ventilation and acidosis occurred within the first four hours of starting isoflurane. Children who required isoflurane or ECLS may develop long-lasting deficits in their functional status. Children with near-fatal asthma are a high-risk group and require improved follow-up in the year following PICU discharge.

Association of CPR simulation program characteristics with simulated and actual performance during paediatric in-hospital cardiac arrest

AIM

To evaluate associations between characteristics of simulated point-of-care cardiopulmonary resuscitation (CPR) training with simulated and actual intensive care unit (ICU) CPR performance, and with outcomes of children after in-hospital cardiac arrest.

METHODS

This is a pre-specified secondary analysis of the ICU-RESUScitation Project; a prospective, multicentre cluster randomized interventional trial conducted in 18 ICUs from October 2016-March 2021. Point-of-care bedside simulations with real-time feedback to allow multidisciplinary ICU staff to practice CPR on a portable manikin were performed and quality metrics (rate, depth, release velocity, chest compression fraction) were recorded. Actual CPR performance was recorded for children 37 weeks post-conceptual age to 18 years who received chest compressions of any duration, and included intra-arrest haemodynamics and CPR mechanics. Outcomes included survival to hospital discharge with favourable neurologic status.

RESULTS

Overall, 18,912 point-of-care simulations were included. Simulation characteristics associated with both simulation and actual performance included site, participant discipline, and timing of simulation training. Simulation characteristics were not associated with survival with favourable neurologic outcome. However, participants in the top 3 sites for improvement in survival with favourable neurologic outcome were more likely to have participated in a simulation in the past month, on a weekday day, to be nurses, and to achieve targeted depth of compression and chest compression fraction goals during simulations than the bottom 3 sites.

CONCLUSIONS

Point-of-care simulation characteristics were associated with both simulated and actual CPR performance. More recent simulation, increased nursing participation, and simulation training during daytime hours may improve CPR performance.

Annual patterns in the outcomes and post-arrest care for pediatric out-of-hospital cardiac arrest: A nationwide multicenter prospective registry in Japan

AIM

Out-of-hospital cardiac arrest (OHCA) has a poor prognosis in children; however, the annual patterns of prognosis and treatment have not been fully investigated.

METHODS

From the Japanese Association for Acute Medicine OHCA registry, a multicenter prospective observational registry in Japan, we identified pediatric patients (zero to 17 years old) between June 2014 and December 2019. The primary outcome was one-month survival. We investigated the annual patterns in patient characteristics, treatment, and one-month prognosis.

RESULTS

During the study period, 1188 patients were eligible for analysis. For all years, the zero-year-old group accounted for a large percentage of the total population (between 30% and 40%). There were significant increases in the rates of bystander-initiated cardiopulmonary resuscitation (CPR; from 50.6% to 62.3%, p = 0.003), dispatcher instructions (from 44.7% to 65.7%, p = 0.001), and adrenaline administration (from 2.4% to 6.9%, p = 0.014) over time, whereas the rate of advanced airway management decreased significantly (from 17.7% to 8.8%, p = 0.003). The odds ratios for one-month survival adjusted for potential resuscitation factors also did not change significantly (from 7.1% to 10.3%, adjusted odds ratio for one-year increment = 0.98, confidence interval: 0.86-1.11).

CONCLUSION

Despite an increase in the rate of bystander-initiated CPR and pre-hospital adrenaline administration, there was no significant change in one-month survival.

Long-Term Outcomes of Extracorporeal Life Support in Respiratory Failure

Although extracorporeal life support is an expensive method with serious risks of complications, it is nowadays a well-established and generally accepted method of organ support. In patients with severe respiratory failure, when conventional mechanical ventilation cannot ensure adequate blood gas exchange, veno-venous extracorporeal membrane oxygenation (ECMO) is the method of choice. An improvement in oxygenation or normalization of acid-base balance by itself does not necessarily mean an improvement in the outcome but allows us to prevent potential negative effects of mechanical ventilation, which can be considered a crucial part of complex care leading potentially to an improvement in the outcome. The disconnection from ECMO or discharge from the intensive care unit should not be viewed as the main goal, and the long-term outcome of the ECMO-surviving patients should also be considered. Approximately three-quarters of patients survive the veno-venous ECMO, but various (both physical and psychological) health problems may persist. Despite these, a large proportion of these patients are eventually able to return to everyday life with relatively little limitation of respiratory function. In this review, we summarize the available knowledge on long-term mortality and quality of life of ECMO patients with respiratory failure.

Long-Term Functional Outcomes at 1-Year After Hospital Discharge in Critically Ill Neonates With Congenital Diaphragmatic Hernia

OBJECTIVES

Congenital diaphragmatic hernia (CDH) is a birth defect associated with long-term morbidity. Our objective was to examine longitudinal change in Functional Status Scale (FSS) after hospital discharge in CDH survivors.

DESIGN

Single-center retrospective cohort study.

SETTING

Center for comprehensive CDH management at a quaternary, free-standing children's hospital.

PATIENTS

Infants with Bochdalek CDH were admitted to the ICU between January 2009 and December 2019 and survived until hospital discharge.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One hundred forty-two infants (58% male, mean birth weight 3.08 kg, 80% left-sided defects) met inclusion criteria. Relevant clinical data were extracted from the medical record to calculate FSS (primary outcome) at hospital discharge and three subsequent outpatient follow-up time points. The median (interquartile range [IQR]) FSS score at hospital discharge was 8.0 (7.0-9.0); 39 patients (27.5%) had at least moderate impairment (FSS ≥ 9). Median (IQR) FSS at 0- to 6-month ( n = 141), 6- to 12-month ( n = 141), and over 12-month ( n = 140) follow-up visits were 7.0 (7.0-8.0), 7.0 (6.0-8.0), and 6.0 (6.0-7.0), respectively. Twenty-one patients (15%) had at least moderate impairment at over 12-month follow-up; median composite FSS scores in the over 12-month time point decreased by 2.0 points from hospital discharge. Median feeding domain scores improved by 1.0 (1.0-2.0), whereas other domain scores remained without impairment. Multivariable analysis demonstrated right-sided, C- or D-size defects, extracorporeal membrane oxygenation use, cardiopulmonary resuscitation, and chromosomal anomalies were associated with impairment.

CONCLUSIONS

The majority of CDH survivors at our center had mild functional status impairment (FSS ≤ 8) at discharge and 1-year follow-up; however, nearly 15% of patients had moderate impairment during this time period. The feeding domain had the highest level of functional impairment. We observed unchanged or improving functional status longitudinally over 1-year follow-up after hospital discharge. Longitudinal outcomes will guide interdisciplinary management strategies in CDH survivors.

Developmental Outcomes Following Abusive Head Trauma in Infancy: A Systematic Review

OBJECTIVE

A systematic review of the literature was conducted to identify measures used to evaluate developmental outcomes after abusive head trauma (AHT), as well as describe outcomes among those with AHT, and explore factors and interventions influencing such outcomes.

DESIGN

This systematic review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. The protocol is in PROSPERO, registration number CRD42020179592. On April 17, 2020, OVID Medline, Embase, OVID PsycINFO, Web of Science, CINAHL, Cochrane Library, and Google Scholar were searched (since inception). Inclusion criteria included original, peer-reviewed study data; AHT exposure; infants younger than 24 months at time of AHT; and evaluation of developmental outcomes. Reviewers independently evaluated studies for inclusion and assessed risk of bias using the Effective Public Health Practice Project quality assessment tool for quantitative studies. A descriptive synthesis approach was utilized as variability of study designs, follow-up periods, and outcome assessment tools precluded a meta-analytic approach.

RESULTS

Fifty-nine studies were included; 115 assessment tools were used to evaluate developmental outcomes; and 42 studies examined factors influencing outcomes. Two studies evaluated interventions. Five percent of studies ( n = 3) were rated low risk of bias.

CONCLUSIONS

Notable variation was observed in terms of case ascertainment criteria. Developmental outcomes after AHT have been assessed in a manner that limits understanding of how AHT impacts development, as well as the efficacy of interventions intended to improve outcomes. Researchers and clinicians are encouraged to adopt consistent diagnostic and assessment approaches.

Performance of a Provider-Assigned Functional Outcome Score in Critically Ill Children

OBJECTIVES

Determine agreement between Pediatric Cerebral Performance Category (PCPC) scores integrated into clinical workflow and traditional investigator-assigned scores.

DESIGN

Longitudinal study.

SETTING

A single-center quaternary-care academic institution.

SUBJECTS

Children admitted to the PICU between November 2019 and April 2020.

INTERVENTIONS

Providers assigned PCPC scores as part of daily workflow. Investigators assigned scores using retrospective chart review.

MEASUREMENTS AND MAIN RESULTS

Of 803 patients admitted to the PICU, 782 survived and were included. Admission and discharge scores were recorded in 95% and 90% of patients, respectively. Agreement between provider- and investigator-assigned scores was excellent, with a weighted kappa of 0.87 (95% CI, 0.84-0.90) and 0.80 (95% CI, 0.76-0.84) for admission and discharge.

CONCLUSIONS

Provider-assigned PCPC scores, documented as standard of care, are largely concordant with retrospective investigator-assigned scores. Measurement of cognitive functional status can be successfully integrated into daily provider workflow for use in the clinical, quality improvement, and research arenas.

Association of Prehospital Physician Presence During Pediatric Out-of-Hospital Cardiac Arrest With Neurologic Outcomes

OBJECTIVES

To examine the association of prehospital physician presence with neurologic outcomes of pediatric patients with out-of-hospital cardiac arrest (OHCA).

DESIGN

Retrospective cohort study.

SETTING

Data from the Japanese Association for Acute Medicine-OHCA Registry.

INTERVENTIONS

None.

PATIENTS

Pediatric patients (age 17 yr old or younger) registered in the database between June 2014 and December 2019.

MEASUREMENT AND MAIN RESULTS

We used logistic regression models with stabilized inverse probability of treatment weighting (IPTW) to estimate the associated treatment effect of a prehospital physician with 1-month neurologically intact survival. Secondary outcomes included in-hospital return of spontaneous circulation (ROSC) and 1-month survival after OHCA. A total of 1,187 patients (276 in the physician presence group and 911 in the physician absence group) were included (median age 3 yr [interquartile range 0-14 yr]; 723 [61%] male). Comparison of the physician presence group, versus the physician absence, showed 1-month favorable neurologic outcomes of 8.3% (23/276) versus 3.6% (33/911). Physician presence was associated with greater odds of 1-month neurologically intact survival after stabilized IPTW adjustment (adjusted odds ratio [aOR] 1.98, 95% CI 1.08-3.66). We also found an association in the secondary outcome between physician presence, opposed to absence, and in-hospital ROSC (aOR 1.48, 95% CI 1.08-2.04). However, we failed to identify an association with 1-month survival (aOR 1.49, 95% CI 0.97-2.88).

CONCLUSIONS

Among pediatric patients with OHCA, prehospital physician presence, compared with absence, was associated almost two-fold greater odds of 1-month favorable neurologic outcomes.

Calcium use during paediatric in-hospital cardiac arrest is associated with worse outcomes

AIM

To evaluate associations between calcium administration and outcomes among children with in-hospital cardiac arrest and among specific subgroups in which calcium use is hypothesized to provide clinical benefit.

METHODS

This is a secondary analysis of observational data collected prospectively as part of the ICU-RESUScitation project. Children 37 weeks post-conceptual age to 18 years who received chest compressions in one of 18 intensive care units from October 2016-March 2021 were eligible. Data included child and event characteristics, pre-arrest laboratory values, pre- and intra-arrest haemodynamics, and outcomes. Outcomes included sustained return of spontaneous circulation (ROSC), survival to hospital discharge, and survival to hospital discharge with favourable neurologic outcome. A propensity score weighted cohort was used to evaluate associations between calcium use and outcomes. Subgroups included neonates, and children with hyperkalaemia, sepsis, renal insufficiency, cardiac surgery with cardiopulmonary bypass, and calcium-avid cardiac diagnoses.

RESULTS

Of 1,100 in-hospital cardiac arrests, median age was 0.63 years (IQR 0.19, 3.81); 450 (41%) received calcium. Among the weighted cohort, calcium use was not associated with sustained ROSC (aOR, 0.87; CI95 0.61-1.24; p = 0.445), but was associated with lower rates of both survival to hospital discharge (aOR, 0.68; CI95 0.52-0.89; p = 0.005) and survival with favourable neurologic outcome at hospital discharge (aOR, 0.75; CI95 0.57-0.98; p = 0.038). Among subgroups, calcium use was associated with lower rates of survival to hospital discharge in children with sepsis and renal insufficiency.

CONCLUSIONS

Calcium use was common during paediatric in-hospital cardiac arrest and associated with worse outcomes at hospital discharge.

Consensus-Based Evaluation of Outcome Measures in Pediatric Stroke Care: A Toolkit

Following a pediatric stroke, outcome measures selected for monitoring functional recovery and development vary widely. We sought to develop a toolkit of outcome measures that are currently available to clinicians, possess strong psychometric properties, and are feasible for use within clinical settings. A multidisciplinary group of clinicians and scientists from the International Pediatric Stroke Organization comprehensively reviewed the quality of measures in multiple domains described in pediatric stroke populations including global performance, motor and cognitive function, language, quality of life, and behavior and adaptive functioning. The quality of each measure was evaluated using guidelines focused on responsiveness and sensitivity, reliability, validity, feasibility, and predictive utility. A total of 48 outcome measures were included and were rated by experts based on the available evidence within the literature supporting the strengths of their psychometric properties and practical use. Only three measures were found to be validated for use in pediatric stroke: the Pediatric Stroke Outcome Measure, the Pediatric Stroke Recurrence and Recovery Questionnaire, and the Pediatric Stroke Quality of Life Measure. However, multiple additional measures were deemed to have good psychometric properties and acceptable utility for assessing pediatric stroke outcomes. Strengths and weaknesses of commonly used measures including feasibility are highlighted to guide evidence-based and practicable outcome measure selection. Improving the coherence of outcome assessment will facilitate comparison of studies and enhance research and clinical care in children with stroke. Further work is urgently needed to close the gap and validate measures across all clinically significant domains in the pediatric stroke population.

Nitric Oxide on Extracorporeal Membrane Oxygenation in Neonates and Children (NECTAR Trial): Protocol for a Randomized Controlled Trial

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) provides support for the pulmonary or cardiovascular function of children in whom the predicted mortality risk remains very high. The inevitable host inflammatory response and activation of the coagulation cascade due to the extracorporeal circuit contribute to additional morbidity and mortality in these patients. Mixing nitric oxide (NO) into the sweep gas of ECMO circuits may reduce the inflammatory and coagulation cascade activation during ECMO support.

OBJECTIVE

The purpose of this study is to test the feasibility and safety of mixing NO into the sweep gas of ECMO systems and assess its effect on inflammation and coagulation system activation through a pilot randomized controlled trial.

METHODS

The Nitric Oxide on Extracorporeal Membrane Oxygenation in Neonates and Children (NECTAR) trial is an open-label, parallel-group, pilot randomized controlled trial to be conducted at a single center. Fifty patients who require ECMO support will be randomly assigned to receive either NO mixed into the sweep gas of the ECMO system at 20 ppm for the duration of ECMO or standard care (no NO) in a 1:1 ratio, with stratification by support type (veno-venous vs veno-arterial ECMO).

RESULTS

Outcome measures will focus on feasibility (recruitment rate and consent rate, and successful inflammatory marker measurements), the safety of the intervention (oxygenation and carbon dioxide control within defined parameters and methemoglobin levels), and proxy markers of efficacy (assessment of cytokines, chemokines, and coagulation factors to assess the impact of NO on host inflammation and coagulation cascade activation, clotting of ECMO components, including computer tomography scanning of oxygenators for clot assessments), bleeding complications, as well as total blood product use. Survival without ECMO and the length of stay in the pediatric intensive care unit (PICU) are clinically relevant efficacy outcomes. Long-term outcomes include neurodevelopmental assessments (Ages and Stages Questionnaire, Strength and Difficulties Questionnaire, and others) and quality of life (Pediatric Quality of Life Inventory and others) measured at 6 and 12 months post ECMO cannulation. Analyses will be conducted on an intention-to-treat basis.

CONCLUSIONS

The NECTAR study investigates the safety and feasibility of NO as a drug intervention during extracorporeal life support and explores its efficacy. The study will investigate whether morbidity and mortality in patients treated with ECMO can be improved with NO. The intervention targets adverse outcomes in patients who are supported by ECMO and who have high expected mortality and morbidity. The study will be one of the largest randomized controlled trials performed among pediatric patients supported by ECMO.

Anticoagulation practices associated with bleeding and thrombosis in pediatric extracorporeal membrane oxygenation; a multi-center secondary analysis

To determine associations between anticoagulation practices and bleeding and thrombosis during pediatric extracorporeal membrane oxygenation (ECMO), we performed a secondary analysis of prospectively collected data which included 481 children (<19 years), between January 2012 and September 2014. The primary outcome was bleeding or thrombotic events. Bleeding events included a blood product transfusion >80 ml/kg on any day, pulmonary hemorrhage, or intracranial bleeding, Thrombotic events included pulmonary emboli, intracranial clot, limb ischemia, cardiac clot, and arterial cannula or entire circuit change. Bleeding occurred in 42% of patients. Five percent of subjects thrombosed, of which 89% also bled. Daily bleeding odds were independently associated with day prior activated clotting time (ACT) (OR 1.03, 95% CI= 1.00, 1.05, p=0.047) and fibrinogen levels (OR 0.90, 95% CI 0.84, 0.96, p <0.001). Thrombosis odds decreased with increased day prior heparin dose (OR 0.88, 95% CI 0.81, 0.97, p=0.006). Lower ACT values and increased fibrinogen levels may be considered to decrease the odds of bleeding. Use of this single measure, however, may not be sufficient alone to guide optimal anticoagulation practice during ECMO.

Association of Asthma With Treatments and Outcomes in Children With Critical Influenza

BACKGROUND

Hospitalization for severe influenza infection in childhood may result in postdischarge sequelae.

OBJECTIVE

To evaluate inpatient management and postdischarge sequelae in children with critical respiratory illness owing to influenza with or without preexisting asthma.

METHODS

This was a prospective, observational multicenter study of children (aged 8 months to 17 years) admitted to a pediatric intensive care or high-acuity unit (in November 2019 to April 2020) for influenza. Results were stratified by preexisting asthma. Prehospital status, hospital treatments, and outcomes were collected. Surveys at approximately 90 days after discharge evaluated postdischarge health resource use, functional status, and respiratory symptoms.

RESULTS

A total of 165 children had influenza: 56 with preexisting asthma (33.9%) and 109 without it (66.1%; 41.1% and 39.4%, respectively, were fully vaccinated against influenza). Fifteen patients with preexisting asthma (26.7%) and 34 without it (31.1%) were intubated. More patients with versus without preexisting asthma received pharmacologic asthma treatments during hospitalization (76.7% vs 28.4%). Of 136 patients with 90-day survey data (82.4%; 46 with preexisting asthma [33.8%] and 90 without it [66.1%]), a similar proportion had an emergency department/urgent care visit (4.3% vs 6.6%) or hospital readmission (8.6% vs 3.3%) for a respiratory condition. Patients with preexisting asthma more frequently experienced asthma symptoms (78.2% vs 3.3%) and had respiratory specialist visits (52% vs 20%) after discharge. Of 109 patients without preexisting asthma, 10 reported receiving a new diagnosis of asthma (11.1%).

CONCLUSIONS

Respiratory health resource use and symptoms are important postdischarge outcomes after influenza critical illness in children with and without preexisting asthma. Less than half of children were vaccinated for influenza, a tool that could mitigate critical illness and its sequelae.

Effect of a Delirium Screening Tool on Antipsychotic Medication Use in a Pediatric Intensive Care Unit

Objective

Intensive care unit (ICU) delirium has been associated with increased length of hospital stay, morbidity, mechanical ventilation, and health care resource utilization. Antipsychotics are frequently used for ICU delirium management, despite a lack of robust evidence in the literature to support their benefit. Delirium screening may result in pharmacologic or non-pharmacologic treatment.

Methods

In January 2019 we began screening patients admitted to the pediatric ICU (PICU) for delirium using the Cornell Assessment for Pediatric Delirium (CAPD). We compared prescribing rates of antipsychotic medications before and after implementation. We also assessed length of hospital and ICU stay prior to initiating therapy, delirium score prior to initiation of therapy, time after initiation of therapy until score decreased to a level not suggestive of delirium, and continuation of antipsychotics outside of the PICU.

Results

We did not observe a difference in the rate of antipsychotics use. There was, however, an increase in variability between pre- and post-intervention rates of prescribing. Patients who received an antipsychotic medication were hospitalized for an average of 18 days and in the ICU for 14 days prior to the first dose of an antipsychotic agent. They had an average CAPD score of 16, and had an average of 4 scores above 8 prior to starting treatment.

Conclusion

This study highlights the need for additional research to demonstrate the role of antipsychotic medications in managing delirium in the PICU.

Asthma as a comorbidity in COVID-19 pediatric ICU admissions in a large metropolitan children's hospital

RATIONALE

Children contribute to 5% of coronavirus disease of 2019 (COVID-19)-related hospitalizations in the United States. There is mounting evidence suggesting childhood asthma is a risk factor for severe disease. We hypothesized that asthma is associated with longer length of stay (LOS) and need for respiratory support among children admitted to pediatric intensive care unit (PICU) with COVID-19.

METHODS

We reviewed 150 charts of children and young adults with a positive severe acute respiratory syndrome coronavirus 2polymerase chain reaction test admitted to the PICU at Children's National Hospital, Washington, DC between 2020 and 2021. We recorded demographics, anthropometrics, past medical history, clinical course, laboratory findings, imaging, medication usage, respiratory support, and outcomes. Functional Status Scale (FSS), which measures an Intensive Care Unitpatient's physical function, was used to characterize children with multiple comorbidities; FSS and obesity were included as covariates in multivariate analysis. Statistical analysis was performed using SPSS v25.0.

RESULTS

Sixty-Eight patients ages 0-21 years met inclusion criteria. Median age was 14.9 years, 55.9% were female, median Body Mass Index percentile was 62, and 42.6% were African American. Compared with those without asthma, patients with asthma averaged longer LOS (20.7 vs. 10.2 days, p = 0.02), with longer PICU stay (15.9 vs. 7.6 days, p = 0.033) and prolonged maximum respiratory support (8.3 vs. 3.3 days, p = 0.016). Adjusted for obesity and poor physical function (FSS > 6), asthma remained a significant predictor of hospital LOS, PICU LOS, and days on maximum respiratory support.

CONCLUSION

Asthma can cause severe disease with prolonged need for maximum respiratory support among children with COVID-19.

Functional status of pediatric patients with trauma and risk factors for mortality from a single center in China

Introduction

The influence of reduced functional status has become increasingly relevant because of the gradual decline in mortality rate over the recent years. Nonetheless, only a few studies investigating the functional status of patients with trauma at hospital discharge have been conducted. This study aimed to identify the risk factors influencing the mortality rate in pediatric trauma survivors at a pediatric intensive care unit and analyze their functional status using the Functional Status Scale (FSS).

Methods

A retrospective analysis was conducted at Shengjing Hospital of China Medical University. Children admitted to the pediatric intensive care unit between January 2015 and January 2020 who met the trauma diagnostic criteria were included. The FSS score and the Injury Severity Score (ISS) were recorded upon admission and discharge, respectively. Clinical data were compared between the survival and non-survival groups to identify the risk factors for poor prognosis. The risk factors for mortality were identified using multivariate and univariate analyses.

Results

A total of 246 children {59.8%, male; median [interquartile range (IQR)] age: 3 [1-7] years} were diagnosed with trauma (including head trauma, chest trauma, abdominal trauma, and extremity trauma). Of these patients, 207 were discharged, 11 dropped out mid-treatment, and 39 died (hospital mortality rate, 15.9%). Upon admission, the median FSS and trauma scores were 14 (IQR, 11-18) and 22 (IQR, 14-33) points, respectively. At discharge, the FSS score was 8 (IQR, 6-10) points. The patient clinical status improved with a ΔFSS score of -4 (IQR, -7, 0) points. At hospital discharge, 119 (48.3%), 47 (19.1%), 27 (11.0%), 12 (4.8%), and 2 (0.9%) survivors had good, mildly abnormal, moderately abnormal, severely abnormal, and very severely abnormal function, respectively. Reduced functional status in patients was categorized as follows: motor, 46.4%; feeding, 26.1%; sensory, 23.2%; mental, 18.4%; and communication, 17.9%. In the univariate analysis, ISS >25 points, shock, respiratory failure, and coma were independently associated with the mortality rate. Multivariate analysis revealed that the ISS was an independent risk factor for mortality.

Conclusion

The mortality rate of patients with trauma was high. ISS was an independent risk factor for mortality. Mildly reduced functional status remained at discharge and was reported in nearly half of the discharged patients. Motor and feeding functions were the most severely impacted domains.

Functional Status Change Among Infants, Children, and Adolescents Following Extracorporeal Life Support: a Multicenter Report

In our retrospective multicenter study of patients 0 to 18 years of age who survived extracorporeal life support (ECLS) between January 2010 and December 2018, we sought to characterize the functional status scale (FSS) of ECLS survivors, determine the change in FSS from admission to discharge, and examine risk factors associated with development of new morbidity and unfavorable outcome. During the study period, there were 1,325 ECLS runs, 746 (56%) survived to hospital discharge. Pediatric patients accounted for 56%. Most common ECLS indication was respiratory failure (47%). ECLS support was nearly evenly split between veno-arterial and veno-venous (51% vs . 49%). Median duration of ECLS in survivors was 5.5 days. Forty percent of survivors had new morbidity, and 16% had an unfavorable outcome. In a logistic regression, African American patients (OR 1.68, p = 0.01), longer duration of ECLS (OR 1.002, p = 0.004), mechanical (OR 1.79, p = 0.002), and renal (OR 1.64, p = 0.015) complications had higher odds of new morbidity. Other races (Pacific Islanders, and Native Americans) (OR 2.89, p = 0.013), longer duration of ECLS (OR 1.002, p = 0.002), and mechanical complications (OR 1.67, p = 0.026) had higher odds of unfavorable outcomes. In conclusion, in our multi-center 9-year ECLS experience, 56% survived, 40% developed new morbidity, and 84% had favorable outcome. Future studies with larger populations could help identify modifiable risk factors that could help guide clinicians in this fragile patient population.

[Early mobilization in critically ill pediatric patient with ventilatory support. Experience of a high complexity center]

In the pediatric intensive care units (PICU) from our region, early mobilization (EM) in patients requiring ventilatory support is an underreported activity. For this reason, we emphasize the need for epidemiological research that allows us to know the characteristics of this relevant activity in the evolution of critically ill patients. Objective: describe the population, time of onset and frequency which MT is performed in patients who received ventilatory support in a PICU of a public pediatric hospital of Latin America. Materials and methods: descriptive, retrospective, observational study, conducted in a 17-bed medical-surgical PICU of a pediatric hospital in Argentina, between July 1 and December 31, 2019. All patients under 18 years of age requiring invasive mechanical ventilation (IMV) and/or noninvasive mechanical ventilation (NIV) for at least 24hs were included. Results: 196 patients were admitted to the study, of which 124 (63.3%) received IMV and 72 (37.7%) NIV only. During their stay in PICU 143 (73%) subjects received MT and of these, 89 (62%) started MT within the first 3 days of hospitalization. In the MT group 93 (65%) required IMV and 50 (35%) NIV. All patients who were tracheostomized in PICU received MT. Conclusion: Early mobilization in pediatric critically ill patients was feasible and early in more than 70% of the population studied. Neither age, nor weight, nor ventilatory support were barriers or limiting factors for its implementation.

Development and Validation of a Prognostic Model and Bedside Score for the Neurological Outcome in Children with Tuberculous Meningitis

Only a few studies have explored prognostic factors for tuberculous meningitis (TBM) in children, and an easily applicable bedside prognostic score for TBM has not been developed yet. We compared the sociodemographic, clinical, radiological, and cerebrospinal fluid parameters in the cohort of 94 TBM cases aged 1 to 18 years, with at least 6 months of completed follow-up and determined the prognostic factors associated with poor functional outcome. We assessed our proposed prognostic model using both discrimination and calibration and subsequently used the bootstrap method to validate the model internally. We finally derived an easily applicable bedside prognostic score by rounding off the regression coefficients to the nearest integers. A total of 39 (41%) and 55 (59%) patients had poor and good functional outcomes, respectively, at the end of 6 months (12 died, 13%). In multivariate analysis, a high baseline Pediatric Cerebral Performance Category (PCPC) score, brain infarction in neuroimaging, tonic motor posturing, younger age, and stage III TBM were independent predictors of poor functional outcomes. The final model showed good discrimination (area under the curve = 88.2%, P < 0.001) and good calibration (Hosmer-Lemeshow test, P = 0.53). Bootstrapping also confirmed the internal validity of this model. The PITAS (PCPC score [P], brain infarction in neuroimaging [I], tonic motor posturing [T], age [A], and stage of TBM [S]) score developed from this model has a score ranging from 0 to 12, with a higher score predicting a higher risk of poor functional outcome. The PITAS score performed better than medical research council staging alone in predicting poor functional outcomes (area under the curve = 87.1% versus 82.3%). Our study's PITAS score, developed and internally validated, has good sensitivity and specificity in predicting poor functional outcomes in pediatric TBM cases at 6 months.

Neurological complications associated with influenza in hospitalized children

BACKGROUND

Influenza is a known respiratory and potential neurotropic virus. This study aimed to determine the prevalence and outcomes of influenza-related neurological complications among hospitalized children.

METHODS

All medical records of hospitalized children aged <18 years old diagnosed with influenza at a tertiary care hospital in Bangkok were retrospectively reviewed. Influenza infection was confirmed by rapid antigen or reverse transcription polymerase chain reaction tests. Neurological characteristics and clinical outcomes were analyzed using the Pediatric Cerebral Performance Category Scale.

RESULTS

From 2013 to 2018, 397 hospitalized children with a median age of 3.7 years (interquartile range [IQR]: 1.6-6.9) were included. The prevalence of neurological complications, including seizure or acute encephalopathy, was 16.9% (95% confidence interval [CI]: 13.3-20.9). Influenza A and B were identified in 73.1% and 26.9% of the patients, respectively. Among 39 (58.2%) acute symptomatic seizure cases, 25 (37.3%) children had simple febrile seizures, 7 (10.4%) had repetitive seizures, and 7 (10.4%) had provoked seizures with pre-existing epilepsy. For 28 (41.8%) encephalopathy cases, the clinical courses were benign in 20 (29.9%) cases and severe in 8 (11.9%) cases. Ten (14.9%) children needed intensive care monitoring, and 62 (93.5%) fully recovered to their baselines at hospital discharge. Predisposing factors to the neurological complications included a history of febrile seizure (adjusted odds ratio [aOR]: 20.3; 95% CI: 6.6-63.0), pre-existing epilepsy (aOR: 3.6; 95% CI: 1.3-10.2), and a history of other neurological disorders (aOR: 3.5; 95% CI: 1.2-10.2).

CONCLUSIONS

One fifth of hospitalized children with influenza had neurological complications with a favorable outcome. Children with pre-existing neurological conditions were at higher risk for developing neurological complications.

Pediatric Status Epilepticus Severity Score (STEPSS): Predictive Performance of Functional Outcomes: A Prospective Single-Center Study

Objective: To prospectively investigate the predictive value of the modified Status Epilepticus Severity Score (STESS) for pediatric use (STEPSS) regarding unfavorable outcomes in the short term. Methods: Patients diagnosed as status epilepticus in the emergency department between January 2019 and June 2021 at a tertiary center of the University of Health Sciences, Dr. Behcet Uz Children's Hospital, were included in the study. The patients were followed up in the emergency department, neurology clinic, and pediatric intensive care unit until discharge. Demographic and clinical characteristics, STEPSS, and Pediatric Overall Performance Category Scale (POPC) scores were calculated. We defined a Pediatric Overall Performance Category Scale score ≥3 as an unfavorable outcome. We compared the effect of STEPSS on unfavorable outcomes and mortality. Results: 124 children were included. The median age was 33 months (interquartile range 16.2-84.7). Seventy-two (58.1%) patients had acute symptomatic etiology. We found that the STEPSS score with the receiver operating characteristic curve (area under the curve  = 0.917, P < .001) could predict unfavorable outcomes (Pediatric Overall Performance Category Scale score ≥3) in children with status epilepticus. The Youden index (0.76) showed that a STEPSS score >2 was the optimal cutoff point for an unfavorable outcome. We found STEPSS useful in predicting mortality (area under the curve  = 0.853, P < .001). The Youden index (0.58) indicated that a STEPSS >2 was the optimal cutoff for mortality: sensitivity 0.90 (95% confidence interval [CI] 0.58-0.99), specificity 0.67 (95% CI 0.57-0.77), positive predictive value 0.21, negative predictive value 0.98, positive likelihood ratio 2.7, negative likelihood ratio 0.14. Conclusion: We determined that STEPSS can be predicted unfavorable outcomes and mortality. We think that STEPSS can be used as a useful clinical score with further studies and external validations.

Extracorporeal Membrane Oxygenation Outcomes in Children With Preexisting Neurologic Disorders or Neurofunctional Disability

OBJECTIVE

Patient selection for pediatric extracorporeal membrane oxygenation (ECMO) support has broadened over the years to include children with pre-existing neurologic morbidities. We aimed to determine the prevalence and nature of pre-ECMO neurologic disorders or disability and investigate the association between pre-ECMO neurologic disorders or disability and mortality and unfavorable neurologic outcome.

DESIGN

Multicenter retrospective observational cohort study.

SETTING

Eight hospitals reporting to the Pediatric ECMO Outcomes Registry between October 2011 and June 2019.

PATIENTS

Children younger than 18 years supported with venoarterial or venovenous ECMO.

INTERVENTIONS

The primary exposure was presence of pre-ECMO neurologic disorders or moderate-to-severe disability, defined as Pediatric Cerebral Performance Category (PCPC) or Pediatric Overall Performance Category (POPC) 3-5. The primary outcome was unfavorable outcome at hospital discharge, defined as in-hospital mortality or survival with moderate-to-severe disability (discharge PCPC 3-5 with deterioration from baseline).

MEASUREMENTS AND MAIN RESULTS

Of 598 children included in the final cohort, 68 of 598 (11%) had a pre-ECMO neurologic disorder, 70 of 595 (12%) had a baseline PCPC 3-5, and 189 of 592 (32%) had a baseline POPC 3-5. The primary outcome of in-hospital mortality ( n = 267) or survival with PCPC 3-5 with deterioration from baseline ( n = 39) was observed in 306 of 598 (51%). Overall, one or more pre-ECMO neurologic disorders or disability were present in 226 of 598 children (38%) but, after adjustment for age, sex, diagnostic category, pre-ECMO cardiac arrest, and ECMO mode, were not independently associated with increased odds of unfavorable outcome (unadjusted odds ratio [OR], 1.34; 95% CI, 1.07-1.69; multivariable adjusted OR, 1.30; 95% CI, 0.92-1.82).

CONCLUSIONS

In this exploratory study using a multicenter pediatric ECMO registry, more than one third of children requiring ECMO support had pre-ECMO neurologic disorders or disability. However, pre-existing morbidities were not independently associated with mortality or unfavorable neurologic outcomes at hospital discharge after adjustment for diagnostic category and other covariates.

Neonatal Aneurysm Rupture in a Child with a De Novo Variant to ANKRD17

Ankyrin repeat domain 17 (ANKRD17) is postulated to play a role in the integrity of blood vessels and has been reported to be associated with developmental delays, epilepsy, and growth restriction. Whereas ANKRD17-deficient mice have been demonstrated to experience catastrophic hemorrhages, vascular malformations have not been reported in human patients with pathogenic variants to ANKRD17. We report a term male neonate with a heterozygous de novo variant to ANKRD17 (ANKRD17; c6988 C > G, P.[P2330a]) who experienced subarachnoid hemorrhage from a ruptured aneurysm involving the left middle cerebral artery. He experienced acute symptomatic seizures and required clipping of his aneurysm at 35 days of life, later progressing to developing multifocal drug-resistant epilepsy. To our knowledge, this case represents the first report of a cerebrovascular malformation from a patient with ANKRD17. Further work is needed to investigate whether pathogenic variants to ANKRD17 can lead to cerebral aneurysms or other cerebrovascular malformations in children.

Sodium Bicarbonate Use During Pediatric Cardiopulmonary Resuscitation: A Secondary Analysis of the ICU-RESUScitation Project Trial

OBJECTIVES

To evaluate associations between sodium bicarbonate use and outcomes during pediatric in-hospital cardiac arrest (p-IHCA).

DESIGN

Prespecified secondary analysis of a prospective, multicenter cluster randomized interventional trial.

SETTING

Eighteen participating ICUs of the ICU-RESUScitation Project (NCT02837497).

PATIENTS

Children less than or equal to 18 years old and greater than or equal to 37 weeks post conceptual age who received chest compressions of any duration from October 2016 to March 2021.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Child and event characteristics, prearrest laboratory values (2-6 hr prior to p-IHCA), pre- and intraarrest hemodynamics, and outcomes were collected. In a propensity score weighted cohort, the relationships between sodium bicarbonate use and outcomes were assessed. The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation (ROSC) and survival to hospital discharge with favorable neurologic outcome. Of 1,100 index cardiopulmonary resuscitation events, median age was 0.63 years (interquartile range, 0.19-3.81 yr); 528 (48.0%) received sodium bicarbonate; 773 (70.3%) achieved ROSC; 642 (58.4%) survived to hospital discharge; and 596 (54.2%) survived to hospital discharge with favorable neurologic outcome. Among the weighted cohort, sodium bicarbonate use was associated with lower survival to hospital discharge rate (adjusted odds ratio [aOR], 0.7; 95% CI, 0.54-0.92; p = 0.01) and lower survival to hospital discharge with favorable neurologic outcome rate (aOR, 0.69; 95% CI, 0.53-0.91; p = 0.007). Sodium bicarbonate use was not associated with ROSC (aOR, 0.91; 95% CI, 0.62-1.34; p = 0.621).

CONCLUSIONS

In this propensity weighted multicenter cohort study of p-IHCA, sodium bicarbonate use was common and associated with lower rates of survival to hospital discharge.

Long-Term Outcomes after Non-Traumatic Out-of-Hospital Cardiac Arrest in Pediatric Patients: A Systematic Review

Long-term outcomes after non-traumatic pediatric out-of-hospital cardiac arrest (OHCA) are not well understood. This systematic review aimed to summarize long-term outcomes (1 year and beyond), including overall survival, survival with favorable neurological outcomes, and health-related quality of life (HRQoL) outcomes) amongst pediatric OHCA patients who survived to discharge. Embase, Medline, and The Cochrane Library were searched from inception to October 6, 2021. Studies were included if they reported outcomes at 1 year or beyond after pediatric OHCA. Data abstraction and quality assessment was conducted by three authors independently. Qualitative outcomes were reported systematically. Seven studies were included, and amongst patients that survived to hospital discharge or to 30 days, longer-term survival was at least 95% at 24 months of follow up. A highly variable proportion (range 10–71%) of patients had favorable neurological outcomes at 24 months of follow up. With regard to health-related quality of life outcomes, at a time point distal to 1 year, at least 60% of pediatric non-traumatic OHCA patients were reported to have good outcomes. Our study found that at least 95% of pediatric OHCA patients, who survived to discharge, survived to a time point distal to 1 year. There is a general paucity of data surrounding the pediatric OHCA population.

Post-discharge rehabilitation and functional recovery after pediatric injury

INTRODUCTION

Variability in rehabilitation disposition has been proposed as a trauma center quality metric. Benchmarking rehabilitation disposition is limited by a lack of objective measures of functional impairment at discharge. The primary aim of this study was to determine the relative contribution of patient characteristics and hospitalization factors associated with inpatient and outpatient rehabilitation after discharge. The secondary aims were to evaluate the sensitivity of the Functional Status Scale (FSS) score for identifying functional impairments at hospital discharge and track post-discharge recovery.

PATIENTS AND METHODS

We report a planned secondary analysis of a prospective observational study of seriously injured children (<15 years old) enrolled at seven pediatric trauma centers. Functional Status Scale (FSS) score was measured for pre-injury, hospital discharge, and 6-month follow-up timepoints. Multinomial logistic regression identified factors associated with three dispositions: home without rehabilitation services, home with outpatient rehabilitation, and inpatient rehabilitation. Relative weight analysis was used to identify the impact of individual factors associated with inpatient or outpatient rehabilitation disposition.

RESULTS

We analyzed 427 children with serious injuries. Functional impairment at discharge was present in 103 (24.1%) children, including 43/337 (12.8%) discharged without services, 12/38 (31.6%) discharged with outpatient rehabilitation, and 44/47 (93.6%) discharged to inpatient rehabilitation. In multivariable modeling, variables most contributing to prediction of inpatient rehabilitation were severe initial Glasgow coma scale (GCS), injured body region, and functional impairment at discharge. Severe initial GCS, private insurance, and extremity injury were independently associated with disposition with outpatient rehabilitation. Patients discharged without services or with outpatient rehabilitation most frequently had motor impairments that improved during the next 6 months. Patients discharged to inpatient rehabilitation had impairments in all domains, with many improving within 6 months. A higher proportion of patients discharged to inpatient rehabilitation had residual impairments at follow-up.

CONCLUSION

Injury characteristics and discharge impairment were associated with discharge to inpatient rehabilitation. The FSS score identified impairments needing inpatient rehabilitation and characterized improvements after discharge. Less severe impairments needing outpatient rehabilitation were not identified by the FSS score.

Chronic critical illness and post-intensive care syndrome: from pathophysiology to clinical challenges

Background

Post‐intensive care syndrome (PICS) encompasses physical, cognition, and mental impairments persisting after intensive care unit (ICU) discharge. Ultimately it significantly impacts the long‐term prognosis, both in functional outcomes and survival. Thus, survivors often develop permanent disabilities, consume a lot of healthcare resources, and may experience prolonged suffering. This review aims to present the multiple facets of the PICS, decipher its underlying mechanisms, and highlight future research directions.

Main text

This review abridges the translational data underlying the multiple facets of chronic critical illness (CCI) and PICS. We focus first on ICU-acquired weakness, a syndrome characterized by impaired contractility, muscle wasting, and persisting muscle atrophy during the recovery phase, which involves anabolic resistance, impaired capacity of regeneration, mitochondrial dysfunction, and abnormalities in calcium homeostasis. Second, we discuss the clinical relevance of post-ICU cognitive impairment and neuropsychological disability, its association with delirium during the ICU stay, and the putative role of low-grade long-lasting inflammation. Third, we describe the profound and persistent qualitative and quantitative alteration of the innate and adaptive response. Fourth, we discuss the biological mechanisms of the progression from acute to chronic kidney injury, opening the field for renoprotective strategies. Fifth, we report long-lasting pulmonary consequences of ARDS and prolonged mechanical ventilation. Finally, we discuss several specificities in children, including the influence of the child’s pre-ICU condition, development, and maturation.

Conclusions

Recent understandings of the biological substratum of the PICS’ distinct features highlight the need to rethink our patient trajectories in the long term. A better knowledge of this syndrome and precipitating factors is necessary to develop protocols and strategies to alleviate the CCI and PICS and ultimately improve patient recovery.

Neurological impairment in children with acute liver failure following liver transplantation-A single-center experience

BACKGROUND

Although overall survival of ALF has improved, neurological restoration after recovery from ALF may not always be satisfactory. The purpose of this study was to investigate the occurrence and possible causes of NI in children with ALF following LT.

METHODS

We retrospectively examined all children younger than 16 years old with ALF who subsequently underwent LT at our center between January 2005 and December 2016. NI was assessed in December 2016 using the six-point Pediatric Cerebral Performance Category score and was defined as any increase in the score.

RESULTS

There were 62 children with median age 10 months (quartile range 5-34). The etiology of ALF was indeterminate in 47 children (75.8%). The median duration from admission to LT was 5.5 days (quartile range 4-7), and 96.8% (60/62) received living donor LT. The overall survival was 83.9% (52/62) in a median follow-up period of 4.2 years. Mild-to-moderate NI was observed in 23.1% (12/52) of the survivors. Possible causes of NI were underlying systemic disease (n = 3), perioperative brain lesion (n = 2), and unclassified (n = 7). All seven patients with unclassified NI were less than 12 months old. The unclassified NI causes were presumed to be ALF, its perioperative care, and the vulnerable infant brain.

CONCLUSIONS

NI in children with ALF following LT was not rare and should be prevented. Further investigations are required to clarify the characteristics of the patients with unclassified NI.
