Project description:Introduction: Septic shock remains amongst the leading causes of childhood mortality. Therapeutic options to support children with septic shock refractory to initial resuscitation with fluids and inotropes are limited. Recently, the combination of intravenous hydrocortisone with high dose ascorbic acid and thiamine (HAT therapy), postulated to reduce sepsis-related organ dysfunction, has been proposed as a safe approach with potential for mortality benefit, but randomized trials in paediatric patients are lacking. We hypothesize that protocolised early use of HAT therapy ("metabolic resuscitation") in children with septic shock is feasible and will lead to earlier resolution of organ dysfunction. Here, we describe the protocol of the Resuscitation in Paediatric Sepsis Using Metabolic Resuscitation-A Randomized Controlled Pilot Study in the Paediatric Intensive Care Unit (RESPOND PICU). Methods and Analysis: The RESPOND PICU study is an open label randomized-controlled, two-sided multicentre pilot study conducted in paediatric intensive care units (PICUs) in Australia and New Zealand. Sixty children aged between 28 days and 18 years treated with inotropes for presumed septic shock will be randomized in a 1:1 ratio to either metabolic resuscitation (1 mg/kg hydrocortisone q6h, 30 mg/kg ascorbic acid q6h, 4 mg/kg thiamine q12h) or standard septic shock management. Main outcomes include feasibility of the study protocol and survival free of organ dysfunction censored at 28 days. The study cohort will be followed up at 28-days and 6-months post enrolment to assess neurodevelopment, quality of life and functional status. Biobanking will allow ancillary studies on sepsis biomarkers. Ethics and Dissemination: The study received ethical clearance from Children's Health Queensland Human Research Ethics Committee (HREC/18/QCHQ/49168) and commenced enrolment on June 12th, 2019. The primary study findings will be submitted for publication in a peer-reviewed journal. Trial Registration: Australian and New Zealand Clinical Trials Registry (ACTRN12619000829112). Protocol Version: V1.8 22/7/20.

Project description:ObjectivesTo report the rate of acute stress and posttraumatic stress among children and parents following PICU admission and the relation between family function and posttraumatic stress.DesignProspective, longitudinal, multi-informant observational study. Pediatric patients (n = 69) and parents were recruited in the ICU. They completed measures evaluating acute stress and posttraumatic stress during their hospitalization and at 3-month follow-up. Parents completed measures of family functioning during the hospitalization. Pearson correlations and multiple regression models were used to examine the relations between family functioning and acute stress and posttraumatic stress.SettingAn academic, urban, pediatric hospital in California.PatientsChildren, 8-17 years old, admitted to the PICU for greater than 24 hours and their English- or Spanish-speaking parents.InterventionsNone.Measurements and main resultsAll children endorsed acute stress during their PICU admission, with 51% meeting criteria for acute stress disorder. At 3-month follow-up, 53% of the children continued to endorse posttraumatic stress with 13% meeting criteria for posttraumatic stress disorder. Among parents, 78% endorsed acute stress during admission with 30% meeting criteria for acute stress disorder, and at follow-up, 35% endorsed posttraumatic stress with 10% meeting criteria for posttraumatic stress disorder. In multiple linear regression modeling, child acute stress significantly predicted child posttraumatic stress (β = 0.36; p < 0.01). In the parent model, parent acute stress (β = 0.29; p < 0.01) and parent education (β = 0.59; p < 0.00) positively predicted parent's posttraumatic stress. Family function was not a predictor of either's posttraumatic stress.ConclusionsBoth children and parents have alarmingly high rates of acute stress and posttraumatic stress following the child's PICU admission. Although family function did not emerge as a predictor in this study, further understanding of the influence of the family and the interplay between child and parent posttraumatic stress is needed to improve our understanding of the model of development of posttraumatic stress in this population to inform the intervention strategies.

Project description:BACKGROUND:Survivors of critical illness in childhood commonly display subsequent psychiatric symptoms including emotional and behavioural difficulties, and manifestations of post-traumatic stress disorder (PTSD). Anomalies in inflammatory profiles are an established finding in these childhood psychiatric conditions. OBJECTIVE:This exploratory study aimed to investigate whether abnormal peripheral blood inflammatory markers measured during paediatric intensive care unit (PICU) admission were associated with psychiatric symptoms after discharge. METHODS:We performed a prospective observational cohort study on 71 children with septic illness, meningoencephalitis and other critical disorders admitted to two PICUs between 2007 and 2010. 3-6 months following discharge, subjects were assessed for global psychiatric risk (ie, presence of emotional and behavioural difficulties on the parental Strengths and Difficulties Questionnaire (SDQ)), and for PTSD risk using the child-rated Impact of Events Scale (IES-8). Inflammatory and related biological markers were transcribed from PICU admission notes (white cell count, lymphocytes, neutrophils, C reactive protein (CRP), platelets, fibrinogen and lactate). FINDINGS:Global psychiatric risk at follow-up was associated with abnormal lymphocyte count during admission (?2=6.757, p=0.014, n=48). In children with sepsis, partial correlation analyses controlling for age and gender highlighted associations between (i) SDQ scores and low lymphocyte count (r=-0.712; p=0.009, n=14), and (ii) IES-8 score and high CRP levels (r=0.823; p=0.006, n=11). These associations remained after correction for multiple comparisons. CONCLUSION:These results support the hypothesis that acute inflammation may play a role in determining the development of psychopathology following PICU admission. CLINICAL IMPLICATIONS:If the findings are replicated, they may help to better highlight which children are at risk of post-PICU psychopathology and appropriately target follow-up.

Project description:Health-Related Quality of Life (HRQoL) after Pediatric Intensive Care Unit (PICU) admission is considered a valuable outcome measure. Yet, data on HRQoL after PICU admission are scarce and often collected in heterogeneous patient groups. The current study aimed to evaluate HRQoL in children with bronchiolitis 6 months after PICU admission, which represents a homogenous patient group. This study was conducted at the Radboud University Medical Centre in the Netherlands. Children admitted to the PICU between November 2019 and April 2020 were eligible. HRQoL was assessed with the "TNO-AZL Preschool children Quality of Life" (TAPQOL) questionnaire and compared to Dutch normative data. Lower scores represent worse HRQoL. HRQoL was assessed in 34 children (response rate 81%), mean age at assessment was 7.6 months (SD 2.5 months), and median length of stay was 5 days (range 1-17). Parents reported significant lower scores on stomach problems (p < 0.001; d = 0.8) and lung problems (p < 0.001; d = 1.2) and significant higher scores on appetite (p < 0.001; d = 0.6) and problem behavior (p < 0.001; d = 0.5) compared to normative data. Effect sizes were moderate to large.ConclusionSignificant differences in several HRQoL domains were found after PICU admission for bronchiolitis compared to normative data. Whereas the domains lung and stomach problems showed significantly impaired scores, most domains revealed HRQoL levels comparable with healthy peers. This study may contribute to the optimization of HRQoL PICU outcomes by highlighting specific HRQoL domains to focus on at admission and during follow-up.What is known• With the decline in PICU mortality, HRQoL became an important outcome measure. Yet, the currently limited number of studies on HRQoL outcomes often involve heterogeneous patient groups. • Bronchiolitis is one of the most frequent reasons for PICU admission, and although a significant part of children admitted for bronchiolitis has a medical history, compared with other reasons for PICU admission, this patient group is relatively homogeneous in terms of age, disease course, and treatment.What is new• In the present study, six months after PICU admission for bronchiolitis, children scored differently on multiple HRQoL domains compared to healthy peers. • Significantly impaired HRQoL scores were reported on lung and stomach problems in comparison to normative data.

Project description:ImportanceThe pediatric intensive care unit (PICU) exposes children to stressful experiences with potential long-term psychological repercussions. However, current understanding of post-PICU psychological outcomes is incomplete.ObjectiveTo systematically review and evaluate reported long-term psychological outcomes among children previously admitted to the PICU.Data sourcesA systematic search of the Cumulative Index to Nursing and Allied Health Literature, Embase, MEDLINE (PubMed), and PsycINFO was conducted from database inception to June 2021. Search terms included phrases related to intensive care (eg, intensive care units and critical care) and terms for psychological disorders (eg, posttraumatic stress disorder, depressive disorder, conduct disorder, and neurodevelopmental disorder) limited to the pediatric population.Study selectionThis systematic review and meta-analysis included randomized clinical trials and observational studies reporting psychological disorders among children younger than 18 years who were admitted to the PICU with follow-up for at least 3 months. Psychological disorders were defined using the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). Children were excluded if they were admitted to the PICU for primary brain conditions (eg, traumatic brain injury, meningoencephalitis, and brain tumors) or discharged to the home for palliative care.Data extraction and synthesisTitles and abstracts were independently screened by 2 reviewers, with data extraction conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. Data were pooled using a random-effects model during meta-analysis.Main outcomes and measuresAge-corrected IQ scores and long-term psychological outcomes measured by scales such as the Child Behavior Checklist (higher scores indicate more behavioral problems) among children admitted to the PICU.ResultsOf 9193 records identified, 31 independent studies (5 randomized clinical trials and 26 observational studies) involving 7786 children (mean age, 7.3 years [95% CI, 6.2-8.4 years]; 4267 boys [54.8%]; race and ethnicity were not reported by all studies) admitted to the PICU were included. Overall, 1 of 19 children (5.3%) to 14 of 16 children (88.0%) previously admitted to the PICU were reported to have at least 1 psychological disorder. Studies that examined posttraumatic stress disorder reported that 6 of 60 children (10.0%) to 31 of 102 children (30.4%) met the diagnostic criteria for the disorder at 3 to 6 months of follow-up. Compared with healthy children, those admitted to the PICU had lower IQ scores at 1 to 2 years of follow-up (mean, 89.40 points [95% CI, 88.33-90.47 points] vs 100.70 points [95% CI, 99.43-101.97 points]; P < .001) and 3 to 5 years of follow-up (mean, 88.54 points [95% CI, 83.92-93.16 points] vs 103.18 [95% CI, 100.36-105.99 points]; P < .001) and greater total emotional and behavioral problems at 4 years of follow-up (mean, 51.69 points [95% CI, 50.37-53.01 points] vs 46.66 points [95% CI, 45.20-48.13 points]; P < .001).Conclusions and relevanceThis systematic review and meta-analysis found a high burden of psychological sequelae among children previously admitted to the PICU, suggesting that risk stratification and early interventions are needed for high-risk groups.
