Midazolam exposure in the paediatric intensive care unit predicts acute post-traumatic stress symptoms in children

Post-traumatic stress disorder in children after discharge from the pediatric intensive care unit: a scoping review

As the prevalence of post-traumatic stress disorder (PTSD) among children discharged from pediatric intensive care unit (PICU) continues to rise, corresponding research efforts have also increased. This scoping review aimed to review the PTSD prevalence, influencing factors, and tools used for PTSD measurements in children discharged from the PICU. This review employed the five-stage framework proposed by Arksey and O'Malley. The data sources included PubMed, Web of Science, Ovid, ScienceDirect, Springer, Scopus, CNKI, and WANFANG. Studies in English or Chinese published up to September 2023 were eligible for inclusion. The search yielded a total of 3536 results, with 31 articles meeting the inclusion criteria. The included studies reported that the prevalence of PTSD ranged from a minimum of 13% to a maximum of 84.6%. Risk factors for PTSD included medical interventions, child-related factors, and family environment. A total of 17 assessment tools for PTSD in PICU patients were reported. Given the significance of PTSD in this pediatric population, further attention, research, and intervention are warranted to help alleviate the burden of PTSD.

The effect of a parental preparation video (Take5) on child and parent anxiety during anaesthetic induction: a protocol for a randomised controlled trial

BACKGROUND

Children undergoing anaesthetic induction experience peri-operative anxiety associated with negative outcomes including emergence delirium, short- and long-term maladaptive behaviour and increased postoperative analgesic requirements. This stems from children's limited ability to communicate, cope, and regulate intense emotions, leading to high dependency on parental emotional regulation. Previous interventions including video modelling, education and distraction techniques before and during anaesthetic induction have demonstrated significant reduction of anxiety levels. No existing interventions combines evidenced-based psychoeducation video with distraction techniques to support parents to moderate peri-operative anxiety. This study aims to test the efficacy of the Take5 video (now referred to as 'Take5'), a short and cost-efficient intervention for child peri-operative anxiety.

METHODS

A randomised, controlled, superiority trial of Take5 compared to standard care. Take5 was developed by paediatric anaesthetists, child psychologists and a consumer panel of parents of children who had experienced surgery and anaesthesia. Children aged 3-10 years presenting for elective surgery at a quaternary paediatric facility will be randomly allocated to the intervention group or standard care. Intervention group parents will be shown Take5 prior to accompanying their child for anaesthesia induction. Primary outcomes include child and parent anxiety at induction, measured by the Modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF), the Peri-operative Adult-Child Behavior Interaction Scale (PACBIS) and the Induction Compliance Checklist (ICC). Secondary outcomes include post-operative pain, emergence delirium, parental satisfaction, cost-effectiveness, parent and child psychological well-being at 3 months post procedure and video intervention acceptability.

DISCUSSION

Perioperative anxiety is associated with negative outcome in children including higher pharmacological intervention, delayed procedures, and poor post-recovery outcomes resulting in financial burden on health systems. Current strategies minimising paediatric procedural distress are resource-intensive and have been inconsistent in reducing anxiety and negative postoperative outcomes. The Take5 video is an evidence-driven resource that is designed to prepare and empower parents. The success of Take5 will be evaluated by measuring differences in patient (acute and 3-month), family (satisfaction, acceptability), clinician (feasibility) and health service (cost) outcomes, with each anticipated to benefit children.

Machine learning to predict poor school performance in paediatric survivors of intensive care: a population-based cohort study

PURPOSE

Whilst survival in paediatric critical care has improved, clinicians lack tools capable of predicting long-term outcomes. We developed a machine learning model to predict poor school outcomes in children surviving intensive care unit (ICU).

METHODS

Population-based study of children < 16 years requiring ICU admission in Queensland, Australia, between 1997 and 2019. Failure to meet the National Minimum Standard (NMS) in the National Assessment Program-Literacy and Numeracy (NAPLAN) assessment during primary and secondary school was the primary outcome. Routine ICU information was used to train machine learning classifiers. Models were trained, validated and tested using stratified nested cross-validation.

RESULTS

13,957 childhood ICU survivors with 37,200 corresponding NAPLAN tests after a median follow-up duration of 6 years were included. 14.7%, 17%, 15.6% and 16.6% failed to meet NMS in school grades 3, 5, 7 and 9. The model demonstrated an Area Under the Receiver Operating Characteristic curve (AUROC) of 0.8 (standard deviation SD, 0.01), with 51% specificity to reach 85% sensitivity [relative Area Under the Precision Recall Curve (rel-AUPRC) 3.42, SD 0.06]. Socio-economic status, illness severity, and neurological, congenital, and genetic disorders contributed most to the predictions. In children with no comorbidities admitted between 2009 and 2019, the model achieved a AUROC of 0.77 (SD 0.03) and a rel-AUPRC of 3.31 (SD 0.42).

CONCLUSIONS

A machine learning model using data available at time of ICU discharge predicted failure to meet minimum educational requirements at school age. Implementation of this prediction tool could assist in prioritizing patients for follow-up and targeting of rehabilitative measures.

Risk Factors for Positive Post-Traumatic Stress Disorder Screening and Associated Outcomes in Children Surviving Acute Respiratory Failure: A Secondary Analysis of the Randomized Evaluation of Sedation Titration for Respiratory Failure Clinical Trial

OBJECTIVES

To identify risk factors and outcomes associated with a positive post-traumatic stress disorder (PTSD) screen following pediatric acute respiratory failure treated with invasive mechanical ventilation.

DESIGN

Nonprespecified secondary analysis of a randomized clinical trial.

SETTING

Thirty-one U.S. PICUs.

PATIENTS

Children in the Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) trial (NCT00814099, ClinicalTrials.gov ) over 8 years old who completed PTSD screening 6 months after discharge.

INTERVENTIONS

RESTORE sites were randomized to a targeted, nurse-directed sedation strategy versus usual care.

MEASUREMENTS AND MAIN RESULTS

PTSD screening was completed by 102 subjects using the Child Post-Traumatic Stress Disorder Symptom Scale; a score of greater than or equal to 11 was considered screening positive for PTSD. Cognitive status was categorized using Pediatric Cerebral Performance Category; health-related quality of life (HRQL) was evaluated using child-reported Pediatric Quality of Life Inventory, Version 4.0. Thirty-one children (30%) screened positive for PTSD. Children with a positive screen endorsed symptoms in all categories: reexperiencing, avoidance, and hyperarousal. Most endorsed that symptoms interfered with schoolwork ( n = 18, 58%) and happiness ( n = 17, 55%). Screening positive was not associated with RESTORE treatment group. In a multivariable logistic model adjusting for age, sex, and treatment group, screening positive was independently associated with lower median income in the family's residential zip code (compared with income ≥ $80,000; income < $40,000 odds ratio [OR], 32.8; 95% CI, 2.3-458.1 and $40,000-$79,999 OR, 15.6; 95% CI, 1.3-182.8), renal dysfunction (OR 5.3, 95% CI 1.7-16.7), and clinically significant pain in the PICU (OR, 8.3; 95% CI, 1.9-35.7). Children with a positive screen experienced decline in cognitive function and impaired HRQL more frequently than children with a negative screen.

CONCLUSIONS

Screening positive for PTSD is common among children following acute respiratory failure and is associated with lower HRQL and decline in cognitive function. Routine PTSD screening may be warranted to optimize recovery.

Risk factors of post-traumatic stress disorder after hospitalization in a pediatric intensive care unit: a systematic literature review

The number of studies on post-traumatic stress disorder after hospitalization in a pediatric intensive care unit raised since 2004. The objective of this systematic review was to summarize and critically examine the literature about risk factors for these children to develop post-traumatic stress disorder following admission to an intensive care unit. The data sources were PubMed, Cochrane, Web of Science, PsycInfo, SUDOC, Scopus, and ScienceDirect. Studies were selected if they were in English or French and published between 01/01/2004 and 31/01/2022. Studies were excluded if patients were less than 1 month old and if no post-traumatic stress disorder was found. The internal validity and risk of bias were assessed using the National Institutes of Health Study Quality Assessment Tools for observational studies and the Ottawa Scale was used for the interventional study. The search yielded 523 results and 22 articles met inclusion criteria. Three common risk factors were identified from the data: parental post-traumatic stress disorder (especially in mothers), severity of illness and delusional memories. Internalizing behavior in children, acute parent and child stress, emergency admission and sepsis are also potential risk factors that require further investigation. The prevalence of this pathology is substantial (between 14 and 36%) and increasing awareness among pediatricians and psychologists seems necessary. Prevention programs are being studied to reduce the incidence of post-traumatic stress disorder in this population. Child and adolescent psychiatry liaison should collaborate with pediatric teams to support this objective.

Brain-Directed Care: Why Neuroscience Principles Direct PICU Management beyond the ABCs

Major advances in pediatric intensive care (PICU) have led to increased child survival. However, the long-term outcomes among these children following PICU discharge are a concern. Most children admitted to PICU are under five years of age, and the stressors of critical illness and necessary interventions can affect their ability to meet crucial developmental milestones. Understanding the neuroscience of brain development and vulnerability can inform PICU clinicians of new ways to enhance and support the care of these most vulnerable children and families. This review paper first explores the evidence-based neuroscience principles of brain development and vulnerability and the impact of illness and care on children's brains and ultimately wellbeing. Implications for clinical practice and training are further discussed to help optimize brain health in children who are experiencing and surviving a critical illness or injury.

Anesthesia and the neurobiology of fear and posttraumatic stress disorder

PURPOSE OF REVIEW

Dysfunction of fear memory systems underlie a cluster of clinically important and highly prevalent psychological morbidities seen in perioperative and critical care patients, most archetypally posttraumatic stress disorder (PTSD). Several sedative-hypnotics and analgesics are known to modulate fear systems, and it is theoretically plausible that clinical decisions of the anesthesiologist could impact psychological outcomes. This review aims to provide a focused synthesis of relevant literature from multiple fields of research.

RECENT FINDINGS

There is evidence in some contexts that unconscious fear memory systems are less sensitive to anesthetics than are conscious memory systems. Opiates may suppress the activation of fear systems and have benefit in the prevention of PTSD following trauma. There is inconsistent evidence that the use of propofol and benzodiazepines for sedation following trauma may potentiate the development of PTSD relative to other drugs. The benefits of ketamine seen in the treatment of major depression are not clearly replicated in PTSD-cluster psychopathologies, and its effects on fear processes are complex.

SUMMARY

There are multiple theoretical mechanisms by which anesthetic drugs can modulate fear systems and clinically important fear-based psychopathologies. The current state of research provides some evidence to support further hypothesis investigation. However, the absence of effectiveness studies and the inconsistent signals from smaller studies provide insufficient evidence to currently offer firm clinical guidance.

Transitions from short to long-term outcomes in pediatric critical care: considerations for clinical practice

Most children are surviving critical illness in highly resourced pediatric intensive care units (PICUs). However, in research studies, many of these children survive with multi-domain health sequelae that has the potential to affect development over many years, termed post-intensive care syndrome-pediatrics (PICS-p). Clinically, there are no recommendations for the assessment and follow-up of children with critical illness as exists for the premature neonatal and congenital heart disease populations. In research studies, primary and secondary outcomes are largely assessed at or prior to hospital discharge, disregarding post-hospital outcomes important to PICU stakeholders. Incorporating longer term outcomes into clinical and research programs, however, can no longer be overlooked. Barriers to outcomes assessments are varied and generalized vs. individualized, but some PICU centers are discovering how to overcome them and are providing this service to families-sometimes specific populations-in need. Research programs and funders are increasingly recognizing the value and need to assess long-term outcomes post-PICU. Finally, we should seek the strong backing of the PICU community and families to insist that long-term outcomes become our new clinical standard of care. PICUs should consider development of a multicenter, multinational collaborative to assess clinical outcomes and optimize care delivery and patient and family outcomes. The aim of this review is to present the potential considerations of implementing long-term clinical follow-up following pediatric critical illness.
