Sophia Observation withdrawal Symptoms-Paediatric Delirium scale: A tool for early screening of delirium in the PICU

Age-specific vulnerability and high prevalence of delirium in pediatric intensive care based on a prospective cohort study

BACKGROUND

Delirium, a neuropsychiatric syndrome characterized by acute disruptions in attention and awareness, significantly impacts children in Pediatric Intensive Care Units (PICUs), leading to prolonged hospitalization, increased infection risk, and dependence on mechanical ventilation. Despite growing recognition, its true burden and risk factors in children remain poorly understood. This prospective cohort study investigated the prevalence, characteristics, and potential therapeutic targets for delirium in 890 children admitted to a tertiary PICU between January and December 2022. Delirium was screened every 12 hours using the validated Cornell Assessment of Pediatric Delirium (CAPD). We analyzed data on demographics, comorbidities, medications, interventions, and clinical outcomes to identify associations with the development of delirium. Our study revealed a high prevalence of delirium, affecting 69.4% (95% CI: 66.33-72.3) of admitted children. Notably, infants were disproportionately affected, accounting for 33.5% of delirium cases. Respiratory diagnoses were significantly associated with delirium (78.6%), while oncology cases had the lowest prevalence (29.4%). Opioid use was identified as a risk factor, increasing the risk of delirium by 45.2%. Furthermore, 97.6% of children with withdrawal syndrome also experienced delirium, highlighting a strong association between these conditions. Delirium was significantly associated with longer PICU stays, and all 20 mortalities during the study period occurred in delirious patients. The adjusted odds ratios from multi-level regression modeling further elucidated the risk factors associated with the development of delirium. This study demonstrates a high prevalence of delirium in PICUs, with infants and those with respiratory diagnoses being particularly vulnerable. Opioid use and withdrawal syndrome emerged as risk factors. Further research is needed to elucidate the mechanisms underlying these associations and develop targeted interventions to prevent, manage, and improve outcomes for children suffering from delirium in critical care settings.

Current Evidence Regarding the Evaluation and Management of Neonatal Delirium

PURPOSE OF REVIEW

Newborns and infants in the neonatal intensive care unit (NICU) may be at uniquely high risk of developing delirium. Because there is a dearth of NICU-focused literature, providers must rely on evidence derived from older children and infants in other care settings to guide management. The literature was rigorously reviewed to highlight evidence specific to newborns and infants and is summarized here.

RECENT FINDINGS

Delirium likely occurs in newborns and infants at similar or higher rates than what is seen in other care settings. Recent literature calls particular attention to the lack of assessment tools validated in a NICU setting. Evidence for the evaluation and management of delirium in the NICU is lacking. More study specific to the NICU is needed to build consensus toward best practice.

Adapting the Cornell assessment of pediatric delirium for Swedish context: translation, cultural validation and inter-rater reliability

BACKGROUND

Pediatric delirium causes prolonged hospital stays, increased costs, and distress for children and caregivers. Currently, there is no delirium screening tool available in Sweden that has been translated, culturally validated, and tested for reliability. This study aimed to translate, culturally adapt, and assess the suitability of the Cornell Assessment of Pediatric Delirium (CAPD) for implementation in Swedish healthcare settings.

METHODS

The CAPD was translated and culturally adapted to Swedish context following the ten-step process recommended by the International Society for Pharmacoeconomics and Outcomes Task Force for Translation and Cultural Adaptation. The Swedish CAPD was tested in the pediatric intensive care unit of Uppsala University Hospital, a tertiary hospital in Sweden. Inter-rater reliability was tested using intraclass correlation coefficient (ICC), with both Registered Nurses (RNs) and Assistant Nurses (ANs) conducting parallel measurements using the Swedish CAPD. A reliability score of ICC > 0.75 was considered indicative of good reliability.

RESULTS

After translation of the CAPD into Swedish, 10 RNs participated in the cultural adaptation process. Issues related to word choice, education, and instructions were addressed. Wording improvements were made to ensure accurate interpretation. Supplementary training sessions were organized to strengthen users' proficiency with the Swedish CAPD. Additional instructions were provided to enhance clarity and usability. Inter-rater reliability testing resulted in an ICC of 0.857 (95% CI: 0.708-0.930), indicating good reliability.

CONCLUSION

This study successfully translated and culturally adapted the CAPD to align with Swedish contextual parameters. The resulting Swedish CAPD demonstrated good inter-rater reliability, establishing its viability as a tool for measuring delirium among pediatric patients in Swedish pediatric intensive care units.

Prospective validation of Sophia observation withdrawal symptoms: A paediatric delirium scale in critically ill children in Denmark

BACKGROUND

Paediatric delirium (PD) is increasingly recognised as a common disorder in critically ill children with a reported prevalence ranging from 9% to 66%. We validated the PD component of the Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale in a Danish setting to provide increased awareness and reliable identification of this critical condition, thereby paving the way for improved pathways to targeted delirium care.

OBJECTIVE

The objectives of this study were to criterion validate the PD component of the SOS-PD screening tool by comparing blinded psychiatric and nurse assessments and to estimate the prevalence of delirium in critically ill children in a Danish context.

METHODS

A prospective observational study was performed on critically ill children aged between 3 m and 18 y, admitted to an intensive care unit, with a hospital stay of 48 h or more. Assessments took place on a fixed weekday over an 18-month period. To test accuracy and criterion validity, bedside nurses' SOS-PD assessments were compared to the reference standard, a diagnostic assessment performed by a child psychiatrist according to the Diagnostic and Statistical Manual-V criteria by use of the Vanderbilt Assessment of Delirium in Infants and Children.

RESULTS

We included 141 children in the study, 30 (21%) of whom were diagnosed with delirium by the child psychiatrist. The accuracy of the delirium diagnosis was 93.6% (95% confidence interval [CI]: 88.3-97.1) among the nurses' SOS-PD assessments compared to the reference standard. The SOS-PD demonstrated a high sensitivity of 83.3% (95% CI: 65.3-94.4) and a high specificity of 96.4% (95% CI: 91.0-99.0) with five false-negative and four false-positive cases.

CONCLUSION

The PD component of the SOS-PD tool has good accuracy and validity for assessments performed by nurses compared to a child psychiatrist's diagnosis in critically ill children in a Danish setting. We recommend the use of the SOS-PD instrument in clinical practice.

Intermittent intravenous paracetamol versus continuous morphine in infants undergoing cardiothoracic surgery: a multi-center randomized controlled trial

BACKGROUND

To determine whether intermittent intravenous (IV) paracetamol as primary analgesic would significantly reduce morphine consumption in children aged 0-3 years after cardiac surgery with cardiopulmonary bypass.

METHODS

Multi-center, randomized, double-blinded, controlled trial in four level-3 Pediatric Intensive Care Units (PICU) in the Netherlands and Belgium. Inclusion period; March 2016-July 2020. Children aged 0-3 years, undergoing cardiac surgery with cardiopulmonary bypass were eligible. Patients were randomized to continuous morphine or intermittent IV paracetamol as primary analgesic after a loading dose of 100 mcg/kg morphine was administered at the end of surgery. Rescue morphine was given if numeric rating scale (NRS) pain scores exceeded predetermined cutoff values. Primary outcome was median weight-adjusted cumulative morphine dose in mcg/kg in the first 48 h postoperative. For the comparison of the primary outcome between groups, the nonparametric Van Elteren test with stratification by center was used. For comparison of the proportion of patients with one or more NRS pain scores of 4 and higher between the two groups, a non-inferiority analysis was performed using a non-inferiority margin of 20%.

RESULTS

In total, 828 were screened and finally 208 patients were included; parents of 315 patients did not give consent and 305 were excluded for various reasons. Fourteen of the enrolled 208 children were withdrawn from the study before start of study medication leaving 194 patients for final analysis. One hundred and two patients received intermittent IV paracetamol, 106 received continuous morphine. The median weight-adjusted cumulative morphine consumption in the first 48 h postoperative in the IV paracetamol group was 5 times lower (79%) than that in the morphine group (median, 145.0 (IQR, 115.0-432.5) mcg/kg vs 692.6 (IQR, 532.7-856.1) mcg/kg; P < 0.001). The rescue morphine consumption was similar between the groups (p = 0.38). Non-inferiority of IV paracetamol administration in terms of NRS pain scores was proven; difference in proportion - 3.1% (95% CI - 16.6-10.3%).

CONCLUSIONS

In children aged 0-3 years undergoing cardiac surgery, use of intermittent IV paracetamol reduces the median weight-adjusted cumulative morphine consumption in the first 48 h after surgery by 79% with equal pain relief showing equipoise for IV paracetamol as primary analgesic.

Pharmacologic Management of Pediatric Burns

Many pediatric patients with burn injuries may be initially treated in a hospital where pediatric specialized care, including resources and trained personnel may be limited. This includes resuscitation in adult emergency departments and inpatient care in mixed adult-pediatric burn units. The intent of this review is to provide a compilation of topics for the adult trained pharmacist or another healthcare practitioner on the management of pediatric patients with burn injuries. This article focuses on several key areas of pharmacologic burn management in the pediatric patient that may differ from the adult patient, including pain and sedation, fluid resuscitation, nutrition support, antimicrobial selection, anticoagulation, and inhalation injury. It is important that all clinicians have resources to help optimize the management of burn injuries in the pediatric population as, in addition to burn injury itself, pediatric patients have different pharmacokinetics and pharmacodynamics affecting which medications are used and how they are dosed. This article highlights several key differences between pediatric and adult patients, providing an additional resource to assist adult-trained pharmacists or other healthcare practitioners with making clinical decisions in the pediatric burn population.

Differences in Delirium Evaluation and Pharmacologic Management in Children With Developmental Delay: A Retrospective Case-Control Study

Delirium is associated with increased mortality and cost, decreased neurocognition, and decreased quality of life in the pediatric intensive care unit (PICU) population. The Cornell Assessment for Pediatric Delirium (CAPD) is used in PICUs for delirium screening but lacks specificity in children with developmental delay (DD). Within a cohort of children receiving pharmacologic treatment for intensive care unit (ICU) delirium, we compared delirium scoring and medication management between children with and without DD. We hypothesized that CAPD scores and treatment decisions would differ between DD and neurotypical (NT) patients. In this retrospective case-control study, we queried the medical record of patients admitted to our PICU with respiratory failure from June 2018 to March 2022 who received antipsychotics typically used for ICU delirium. Antipsychotics prescribed for home use were excluded. Nonparametric statistics compared demographics, CAPD scores, medication choice, dosing (mg/kg), and medication continuation after discharge between those with and without DD based on the ICD-10 codes. Twenty-one DD admissions and 59 NT admissions were included. Groups did not significantly differ by demographics, LOS, drug, or initial dosage. DD patients had higher median CAPD scores at admission (17 vs 13; P = .02) and treatment initiation (18 vs 16.5; P = .05). Providers more frequently escalated doses in DD patients (13/21 vs 21/59; P = .04) and discharged them home on new antipsychotics (7/21 vs 5/59; P = .01). DD patients experience delirium screening and management differently than NT counterparts. Providers should be aware of baseline elevated scores in DD patients and carefully attend to indications for dosage escalation. Further work is needed to understand if prolonged duration, even after hospital discharge, benefits patients, or represents potential disparity in care.

Prospective observational study on the use of continuous intravenous ketamine and propofol infusion for prolonged sedation in critical care

INTRODUCTION

Analgesia and sedation are a priority in paediatric intensive care. The combination of ketamine and propofol is a possible option in patients requiring prolonged or difficult sedation and to reduce the use of benzodiazepines and opiates. The aim of this study was to assess the efficacy and safety of combination ketamine and propofol in continuous infusion for prolonged analgesia/sedation in the paediatric intensive care setting.

PATIENTS AND METHODS

Prospective, observational single-group cohort study in patients aged 1 month to 16 years admitted to the paediatric intensive care unit in 2016-2018 that received ketamine and propofol in continuous infusion for analgesia and sedation. We collected data on demographic and clinical characteristics, analgesia and sedation scores (MAPS, COMFORT-B and SOPHIA), haemodynamic parameters and adverse events.

RESULTS

The study included 32 patients. The maximum dose of ketamine was 1.5 mg/kg/h (interquartile range [IQR], 1-2 mg/kg/h) and the infusion duration was 5 days (IQR, 3-5 days). The maximum dose of propofol was 3.2 mg/kg/h (IQR, 2.5-3.6 mg/kg/h) and the infusion duration, 5 days (IQR, 3-5 days). Thirty (93.7%) patients had previously received midazolam and 29 (90.6%) fentanyl. Analgesia scores did not change after initiation of the ketamine and propofol infusion. There was a statistically significant increase in the COMFORT-B score, but the score remained in the adequate sedation range (12-17). There were small but statistically significant decreases in the mean arterial pressure (from 64 mmHg to 60 mmHg; P = .006) and the diastolic blood pressure (from 50.5 to 48 mmHg; P = .023) 1 h after the initiation of the ketamine and propofol infusion, but this difference was not observed 12 h later and did not require administration of vasoactive drugs. No other major adverse events were detected during the infusion.

CONCLUSIONS

The combination of ketamine and propofol in continuous infusion is a safe treatment in critically ill children that makes it possible to achieve an appropriate level of analgesia and sedation without relevant haemodynamic repercussions.

Clinical application of 'Sophia Observation withdrawal Symptoms-Paediatric Delirium' screening tool in Danish version: A feasibility study

AIMS AND OBJECTIVES

The aims of the present study were investigating the feasibility of: (1) using the Danish version of Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) screening tool in clinical practice and (2) comparing SOS-PD performance to a child psychiatrist's assessment using the diagnostic criteria as a reference standard.

BACKGROUND

Critically ill children risk developing delirium potentially causing discomfort and suffering. Intensive care delirium has a fluctuating course complicating detection. Systematic screening during and after intensive care is central to manage paediatric delirium.

DESIGN AND METHODS

We used a descriptive and comparative design. First aim: Bedside nurses were asked to evaluate their experience of using the SOS-PD. Second aim: We compared the SOS-PD performance with the child psychiatrist assessment in 50 children aged 4 weeks to 18 years.

RESULTS

Nurses found the Danish version of the SOS-PD applicable and easy to use. Of the 50 children included, 13 were diagnosed with delirium by the child psychiatrist. Consistency was found between the SOS-PD score and the child psychiatrist's assessment (88%). We found three false-negative and three false-positive SOS-PD cases. The false-negative cases could be explained by the differences in time periods for the assessments. SOS-PD assessments covered the past 4 h, whereas the psychiatric assessments covered the past 24 h. We assume the false-positive cases represent an acceptable inconsistency between the two assessment methods.

CONCLUSIONS

The Danish version of the SOS-PD appeared suitable for identifying paediatric delirium. Our results emphasised the importance of assessment at least once during each nursing shift to ensure delirium detection around the clock due to the fluctuating course of delirium.

RELEVANCE TO CLINICAL PRACTICE

Implementing the Danish SOS-PD may increase awareness of this critical disorder by improving systematic identification of paediatric delirium in clinical practice paving the way for improved delirium prevention and management.

Pediatric delirium is associated with increased brain injury marker levels in cardiac surgery patients

Despite global consensus on the importance of screening pediatric delirium, correlations between pediatric delirium during acute brain injury and adult delirium are unclear. Therefore, we hypothesized that similar pediatric biomarkers reflect acute brain injury as in adult delirium. We observed pediatric cardiac surgery patients from neonatal age to 18 years, who were admitted to our pediatric intensive care unit after cardiovascular operations between October 2019 to June 2020, up to post-operative day 3 (4 days total). We recorded age, sex, risk score (Risk Adjustment in Congenital Heart Surgery [RACHS-1]), midazolam/dexmedetomidine/fentanyl dosage, and pediatric Sequential Organ Failure Assessment (pSOFA). Richmond Agitation-Sedation Scale (RASS), Cornell Assessment of Pediatric Delirium (CAPD), Face, Leg, Activity, Consolability (FLACC) behavioral scale, and Withdrawal Assessment Tool (WAT-1) scales were used and serum sampling for neuron specific enolase (NSE) was conducted. Consciousness status was considered hierarchical (coma > delirium > normal) and associations between conscious status and NSE were conducted by hierarchical Bayesian modeling. We analyzed 134 data points from 40 patients (median age 12 months). In the multi-regression model, NSE was positively associated with coma [posterior odds ratio (OR) = 1.1, 95% credible interval (CrI) 1.01-1.19] while pSOFA [posterior OR = 1.63, 95% CrI 1.17-2.5], midazolam [posterior OR = 1.02, 95% CrI 1.01-1.04], and dexmedetomidine [posterior OR = 9.52, 95% CrI 1.02-108.85] were also associated. We also evaluated consciousness state probability at each NSE concentration and confirmed both that consciousness was hierarchically sorted and CAPD scores were also associated with NSE [posterior OR = 1.32, 95% CrI 1.09-1.58]. "Eye contact" (r = 0.55) was the most correlated component with NSE within the pain, withdrawal syndrome, and PD items. PD within the hierarchy of consciousness (coma, delirium, normal) and CAPD scores are associated with brain injury marker levels. Using pediatric delirium assessment tools for monitoring brain injury, especially eye contact, is a reliable method for observing PD.

[Effect of sequential sedation and analgesia in preventing delirium and withdrawal symptoms in children after ventilator weaning]

OBJECTIVES

To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning.

METHODS

A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning.

RESULTS

There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01).

CONCLUSIONS

Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

Sedation practices during high dose rate brachytherapy for children with urogenital and perianal rhabdomyosarcoma

BACKGROUND

A novel concept for an organ-preserving treatment of pediatric urogenital and perianal rhabdomyosarcoma includes high dose rate brachytherapy following surgical tumor resection. For the duration of the brachytherapy of 6 days plus 2-day recovery break the patients are not allowed to move and are kept under deep sedation, which can lead to difficult weaning from mechanical ventilation, withdrawal, delirium, and prolonged hospital stay. The aim of this study was to evaluate a protocol which includes a switch from fentanyl to ketamine 3 days prior to extubation to help ensure a rapid extubation and transfer from PICU.

METHODS

Patients who underwent surgical tumor resection of rhabdomyosarcoma and subsequent brachytherapy were treated according to a standardized protocol. We evaluated doses of fentanyl, midazolam and clonidine, time of extubation, length of PICU stay and occurrence of withdrawal symptoms and delirium. We compared fentanyl dose at time of extubation, duration of weaning from mechanical ventilation and time to discharge from PICU with patients after isolated severe traumatic brain injury.

RESULTS

Twentytwo patients (age 39.9 ± 29.8 months) were treated in our PICU to undergo brachytherapy. Extubation was performed 21.6 ± 13.5 h after the last brachytherapy session with an average fentanyl dose of 1.5 ± 0.5 µg/kg/h and patients were discharged from PICU 58.4 ± 30.3 h after extubation, which all is significantly lower compared to the control group (extubation after 88.0 ± 42.2 h, p < 0.001; fentanyl dose at the time of extubation 2.5 ± 0.6 µg/kg/h, p < 0.001; PICU discharge after 130.1 ± 148.4 h, p < 0.009). Withdrawal symptoms were observed in 9 patients and delirium in 13 patients.

CONCLUSION

A standardized analgesia and sedation protocol including an opioid break, scoring systems to detect withdrawal symptoms and delirium, and tapering plans contributes to successful early extubation and discharge from PICU after long-term deep sedation.

Quality improvement intervention to stimulate early mobilization of critically ill children

BACKGROUND

Immobility during hospital stay is associated with muscle weakness, delirium, and delayed neurocognitive recovery. Early mobilization of critically ill adults improves their physical functioning and shortens the duration of mechanical ventilation. However, comparable research in children is lacking.

AIMS

To determine the effects of the implementation of an early mobilization (EM) program on mobility activities for critically ill children and to explore barriers and facilitators and clinical outcomes before and after implementation.

STUDY DESIGN

A prospective single-centre before-and-after study.

METHODS

This study was conducted in a PICU of a large tertiary hospital. Children aged from 3 months to 18 years, with an expected stay of ≥3 days were eligible to participate. In the "before" phase, participants received usual care; in the "after" phase we implemented a multicomponent, multidisciplinary EM protocol. The primary outcome was a change in the process outcome "mobilization activities". Secondary outcomes were PICU staff opinions on mobilization (survey), safety, process measures, involvement of parents and physical therapist, and clinical outcomes (sedative use and prevalence of delirium).

RESULTS

A total of 113 children were included; 55 before and 58 after, with a median age of 31 months (IQR: 10-103) and 35 months (IQR: 7-152), respectively. The number of mobilization activities (per patient per day) had significantly increased from 5 (IQR: 2-7) to 6 (IQR: 4-8) (U = 272185.0; p < .001). PT consultations for mobilization had significantly increased from 23.6% (13/55) to 46.5% (27/58) (X²  = 6.48; p = .011). In both phases, no mobilization-related adverse events were documented. The survey showed that PICU staff found EM of critically ill children useful and feasible. In the after phase, PICU staff rated the perceived benefit of the support of the physical therapist during mobilization activities significantly higher than in the before phase (X²  = 34.80; p < .001).

CONCLUSIONS

Implementation of a structured EM program for critically ill children is feasible and safe.

RELEVANCE TO CLINICAL PRACTICE

It is suggested to start the implementation of a structed EM program with the idendentification of local barriers and facilitators by an interdisciplinary PICU team. Further, an increased presence of physiotherapists on the PICU would improve mobilisation levels, and facilitate mobilisation in critically ill children. Also, they can support and advice PICU nurses and parents in mobilising children.

Recommendations for analgesia and sedation in critically ill children admitted to intensive care unit

We aim to develop evidence-based recommendations for intensivists caring for children admitted to intensive care units and requiring analgesia and sedation. A panel of national paediatric intensivists expert in the field of analgesia and sedation and other specialists (a paediatrician, a neuropsychiatrist, a psychologist, a neurologist, a pharmacologist, an anaesthesiologist, two critical care nurses, a methodologist) started in 2018, a 2-year process. Three meetings and one electronic-based discussion were dedicated to the development of the recommendations (presentation of the project, selection of research questions, overview of text related to the research questions, discussion of recommendations). A telematic anonymous consultation was adopted to reach the final agreement on recommendations. A formal conflict-of-interest declaration was obtained from all the authors. Eight areas of direct interest and one additional topic were considered to identify the best available evidence and to develop the recommendations using the Evidence-to-Decision framework according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. For each recommendation, the level of evidence, the strength of the recommendation, the benefits, the harms and the risks, the benefit/harm balance, the intentional vagueness, the values judgement, the exclusions, the difference of the opinions, the knowledge gaps, and the research opportunities were reported. The panel produced 17 recommendations. Nine were evaluated as strong, 3 as moderate, and 5 as weak. Conclusion: a panel of national experts achieved consensus regarding recommendations for the best care in terms of analgesia and sedation in critically ill children.

Quality of clinical practice guidelines and recommendations for the management of pain, sedation, delirium and iatrogenic withdrawal in pediatric intensive care: a systematic review protocol

INTRODUCTION

Inadequate management of pain and sedation in critically ill children can cause unnecessary suffering and agitation, but also delirium and iatrogenic withdrawal. It is, therefore, important to address these four interrelated conditions together. Some clinical practice guidelines (CPGs) are available for the management of pain and sedation, and a few for delirium and iatrogenic withdrawal in the paediatric intensive care unit; none address the four conditions altogether. Critical appraisal of the quality of CPGs is necessary for their recommendations to be adopted into clinical practice. The aim of this systematic review is to identify and appraise the quality of CPGs and recommendations for management of either pain, sedation, delirium and iatrogenic withdrawal.

METHODS AND ANALYSIS

Researchers will conduct a systematic review in electronic databases (Medline ALL (Ovid), Embase.com, CINAHL with Full Text (EBSCO), JBI EBP Database (Ovid)), guideline repositories and websites of professional societies to identify CPGs published from 2010 to date. They will then combine index and free terms describing CPGs with pain, sedation, delirium and withdrawal. The researchers will include CPGs if they can be applied in the paediatric intensive care population (newborns to 18 years old) and include recommendation(s) for assessment of at least one of the four conditions. Two independent reviewers will screen for eligibility, complete data extraction and quality assessments using the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the AGREE Recommendation Excellence instruments. Researchers will report characteristics, content and recommendations from CPGs in tabulated forms.

ETHICS AND DISSEMINATION

Ethical approval is not required for this systematic review. Results will be published in a peer-reviewed journal.

Four-in-One: A Comprehensive Checklist for the Assessment of Pain, Undersedation, Iatrogenic Withdrawal and Delirium in the PICU: A Delphi Study

OBJECTIVES

Children's pain, undersedation, iatrogenic withdrawal syndrome and delirium often have overlapping symptoms, which makes it difficult to decide why a child in the PICU is not comfortable. Validated assessment tools for these conditions are available, but regular assessment with multiple instruments may be too time-consuming. Therefore, we aimed to develop a new holistic instrument-the mosaIC checklist-that incorporates the assessment of the four conditions.

MATERIALS AND METHODS

We conducted a two-rounds international Delphi study among experts working in PICUs worldwide to find cues that in combination or separately are relevant for the four conditions.

RESULTS

In the first Delphi round, 38 of the 48 enrolled participants (79%) completed a questionnaire; in the second round 32 of 48 (67%). Eventually, 46 cues in eight categories (e.g., facial, vocal/verbal, body movements, sleep /behavioral state, posture/muscle tone, agitation, physiological and contextual) were found relevant. Thirty-three (72%) were considered relevant for pain, 24 for undersedation (52%), 35 for iatrogenic withdrawal syndrome (76%) and 28 (61%) for pediatric delirium. Thirteen cues (28%) were considered relevant for all four conditions; 11's (24%) for only one condition.

CONCLUSION

This Delphi study is the first step in developing a 4-in-1 comprehensive checklist to assess pain, undersedation, iatrogenic withdrawal syndrome and delirium in a holistic manner. Further validation is needed before the checklist can be applied in practice. Application of the mosaIC checklist could help determine what condition is most likely to cause a child's discomfort-and at the same time help reduce the PICU staff's registration burden.

Implementation of a Delirium Bundle for Pediatric Intensive Care Patients

BACKGROUND AND OBJECTIVE

Delirium represents the most common form of acute cerebral dysfunction in critical illness. The prevention, recognition, and treatment of delirium must become the focus of modern pediatric intensive care, as delirium can lead to increased morbidity and mortality. The aim of this study is to evaluate the impact of a delirium bundle consisting of mainly non-pharmacological measures.

MATERIAL AND METHODS

This is a pre-/post-implementation study in an interdisciplinary pediatric intensive care unit of a tertiary care university hospital. In the pre-implementation period, pediatric intensive care delirium was monitored using the Sophia Observation withdrawal Symptoms and Pediatric Delirium scale. After introduction of a delirium bundle consisting of non-pharmacological prevention and treatment measures a period of 4 months was interposed to train the PICU staff and ensure that the delirium bundle was implemented consistently before evaluating the effects in the post-implementation period. Data collection included prevalence of delirium and withdrawal, length of PICU stay, duration of mechanical ventilation, and cumulative dose of sedatives and analgesics.

RESULTS

A total of 792 critically ill children aged 0-18 years were included in this study. An overall delirium prevalence of 30% was recorded in the pre-implementation group and 26% in the post-implementation group (p = 0.13). A significant reduction in the prevalence of pediatric delirium from was achieved in the subgroup of patients under 5 years of age (27.9 vs. 35.8%, p = 0.04) and in patients after surgery for congenital heart disease (28.2 vs. 39.5%, p = 0.04). Young age, length of PICU stay, and iatrogenic withdrawal syndrome were found to be risk factors for developing delirium.

CONCLUSIONS

Based on a validated delirium monitoring, our study gives new information regarding the prevalence of pediatric delirium and the characteristics of intensive care patients at risk for this significant complication. Especially young patients and patients after surgery for congenital heart disease seem to benefit from the implementation of non-pharmacological delirium bundles. Based on our findings, it is important to promote change in pediatric intensive care-toward a comprehensive approach to prevent delirium in critically ill children as best as possible.

Incidence and Factors Associated with Delirium in Children in a Single Pediatric Intensive Care Unit in Brazil

PURPOSE

To identify the incidence of delirium in a Pediatric Intensive Care Unit (PICU); to determine the factors associated with the occurrence of delirium and the agreement between two scales used for detection of pediatric delirium in critically ill children.

DESIGNS AND METHOD

Descriptive longitudinal study carried out in a PICU. The sample consisted of 65 critically ill children admitted to the PICU, with more than 24 h of hospitalization, excluding children with neurological or cognitive impairment, hearing and visual impairment, chronic encephalopathy and declining consent to participate in the study. Two scales were applied, the Cornell Assessment of Pediatric Delirium (CAPD) and the Sophia Observation Withdrawal Symptoms - Pediatric Delirium Scale (SOS_PD). Descriptive and inferential statistical analysis, with a 5% significance level was performed.

RESULTS

Delirium was identified in 7.7% of children, with duration of the disorder of about 2 days. A very good agreement (Kappa = 1; p-value <0.001) between the two scales was identified. CAPD presented positive predictive value of 80.0%. There was a statistical association between the occurrence of delirium and age less than 2 years (p = 0.060); female gender (p = 0.057); use of mechanical pulmonary ventilation (p = 0.034); antiemetics (p = 0.002); anticholinergics (p = 0.044), and changes in serum sodium and potassium (p = 0.053).

CONCLUSION

Demographic, clinical, and pharmacological conditions were associated with the occurrence of delirium.

PRACTICE IMPLICATIONS

Routine monitoring is the first step to any delirium prevention strategies, so delirium screening by the bedside nurse must be valued through a commitment to education and training.

A Systematic Review and Pooled Prevalence of Delirium in Critically Ill Children

OBJECTIVES

Pediatric delirium is a neuropsychiatric disorder with disrupted cerebral functioning due to underlying disease and/or critical care treatment. Pediatric delirium can be classified as hypoactive, hyperactive, and mixed. This systematic review was conducted to estimate the pooled prevalence of pediatric delirium using validated assessment tools in children (Cornell Assessment of Pediatric Delirium, Pediatric Confusion Assessment Method for the ICU, PreSchool Confusion Assessment Method for the ICU, Pediatric Confusion Assessment Method for the ICU Severity Scale, and Sophia Observation Withdrawal Symptoms Pediatric Delirium scale), identify modifiable and nonmodifiable risk factors, and explore the association of pediatric delirium with clinical outcomes.

DATA SOURCES

A systematic search of PubMed, EMBASE, and CINAHL databases was undertaken for full articles pertaining to pediatric delirium prevalence.

STUDY SELECTION

No language or date barriers were set. Studies were included where the following eligibility criteria were met: study design aimed to estimate pediatric delirium prevalence arising from treatment in the intensive care setting, using a validated tool. Only randomized controlled trials, cross-sectional studies, or cohort studies allowing an estimate of the prevalence of pediatric delirium were included.

DATA EXTRACTION

Data were extracted by the primary researcher (D.S.) and accuracy checked by coauthors.

DATA SYNTHESIS

A narrative synthesis and pooled prevalence meta-analysis were undertaken.

CONCLUSIONS

Pediatric delirium, as determined by the Cornell Assessment of Pediatric Delirium score, is estimated to occur in 34% of critical care admissions. Eight of 11 studies reporting on subtype identified hypoactive delirium as most prevalent (46-81%) with each of the three remaining reporting either hyperactive (44%), mixed (57%), or equal percentages of hypoactive and mixed delirium (43%) as most prevalent. The development of pediatric delirium is associated with cumulative doses of benzodiazepines, opioids, the number of sedative classes used, deep sedation, and cardiothoracic surgery. Increased time mechanically ventilated, length of stay, mortality, healthcare costs, and associations with decreased quality of life after discharge were also found. Multi-institutional and longitudinal studies are required to better determine the natural history, true prevalence, long-term outcomes, management strategies, and financial implications of pediatric delirium.

Assessment and Management of Delirium in the Pediatric Intensive Care Unit: A Review

Many critically ill patients suffer from delirium which is associated with significant morbidity and mortality. There is a paucity of data about the incidence, symptoms, or treatment of delirium in the pediatric intensive care unit (PICU). Risk factors for delirium are common in the PICU including central nervous system immaturity, developmental delay, mechanical ventilation, and use of anticholinergic agents, corticosteroids, vasopressors, opioids, or benzodiazepines. Hypoactive delirium is the most common subtype in pediatric patients; however, hyperactive delirium has also been reported. Various screening tools are validated in the pediatric population, with the Cornell Assessment of Pediatric Delirium (CAPD) applicable to the largest age range and able to detect signs and symptoms consistent with both hypo- and hyperactive delirium. Treatment of delirium should always include identification and reversal of the underlying etiology, reserving pharmacologic management for those patients without symptom resolution, or with significant impact to medical care. Atypical antipsychotics (olanzapine, quetiapine, and risperidone) should be used first-line in patients requiring pharmacologic treatment owing to their apparent efficacy and low incidence of reported adverse effects. The choice of atypical antipsychotic should be based on adverse effect profile, available dosage forms, and consideration of medication interactions. Intravenous haloperidol may be a potential treatment option in patients unable to tolerate oral medications and with significant symptoms. However, given the high incidence of serious adverse effects with intravenous haloperidol, routine use should be avoided. Dexmedetomidine should be used when sedation is needed and when clinically appropriate, given the positive impact on delirium. Additional well-designed trials assessing screening and treatment of PICU delirium are needed.

Dexmedetomidine and Iatrogenic Withdrawal Syndrome in Critically Ill Children

BACKGROUND

Iatrogenic withdrawal syndrome is a well-known adverse effect of sedatives and analgesics commonly used in patients receiving mechanical ventilation in the pediatric intensive care unit, with an incidence of up to 64.6%. When standard sedative and analgesic treatment is inadequate, dexmedetomidine may be added. The effect of supplemental dexmedetomidine on iatrogenic withdrawal syndrome is unclear.

OBJECTIVE

To explore the potentially preventive effect of dexmedetomidine, used as a supplement to standard morphine and midazolam regimens, on the development of iatrogenic withdrawal syndrome in patients receiving mechanical ventilation in the pediatric intensive care unit.

METHODS

This retrospective observational study used data from patients on a 10-bed general pediatric intensive care unit. Iatrogenic withdrawal syndrome was measured using the Sophia Observation withdrawal Symptoms-scale.

RESULTS

In a sample of 102 patients, the cumulative dose of dexmedetomidine had no preventive effect on the development of iatrogenic withdrawal syndrome (P = .19). After correction for the imbalance in the baseline characteristics between patients who did and did not receive dexmedetomidine, the cumulative dose of midazolam was found to be a significant risk factor for iatrogenic withdrawal syndrome (P < .03).

CONCLUSION

In this study, supplemental dexmedetomidine had no preventive effect on iatrogenic withdrawal syndrome in patients receiving sedative treatment in the pediatric intensive care unit. The cumulative dose of midazolam was a significant risk factor for iatrogenic withdrawal syndrome.

State of the science in pediatric ICU delirium: An integrative review

Delirium is a complication of critical illness associated with poor outcomes. Although widely studied in adults, comparatively little is understood about delirium in pediatric intensive care units (ICUs). The purpose of this integrative review is to determine the extent and nature of current evidence, identify gaps in the literature, and outline future areas for investigation of pediatric ICU delirium. Eligible articles included research reports of delirium in pediatric ICU samples published in English since 2009. After an extensive literature search and consideration for inclusion/exclusion criteria, 22 articles were chosen for review. Delirium was highly prevalent in the ICU. Delirium episodes developed early in hospitalization, lasted several days, and consisted of hypoactive or mixed motor subtypes. Frequently identified independent risk factors included young age, developmental delay, mechanical ventilation, and benzodiazepine exposure. Pediatric delirium was independently associated with increased length of stay, costs, and mortality. The long-term cognitive, psychological, and functional morbidities associated with pediatric delirium remain largely unknown. Few researchers have implemented interventions to prevent or manage delirium. There was little evidence for the efficacy or safety of pharmacological management. Multicomponent delirium bundles may significantly decrease delirium incidence. Key quality issues among studies included variation in delirium screening, low levels of evidence (i.e., observational studies), and limited ability to determine intervention efficacy in quasi-experimental designs. Although the quantity and quality of pediatric delirium research has rapidly increased, further studies are needed to understand the long-term effects of pediatric delirium and determine the efficacy and safety of interventions for prevention and management.

The Validity and Reliability of the Japanese Version of the Cornell Assessment of Pediatric Delirium

OBJECTIVES

To examine validity and reliability of the Japanese version of the Cornell Assessment of Pediatric Delirium.

DESIGN

Prospective double-blinded observational cohort study.

SETTING

Eight-bed mixed PICU (post-surgical and internal medicine) from May 2017 to June 2018.

PATIENTS

All children between the ages of 0-13 years who were admitted to the PICU for at least 24 hours were eligible for inclusion, as long as the child was arousable to verbal stimulation.

INTERVENTIONS

Two nurses simultaneously and independently assessed each patient for pediatric delirium with the Japanese version of the Cornell Assessment of Pediatric Delirium; this was compared to the gold standard of psychiatric diagnosis based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition standards.

MEASUREMENTS AND MAIN RESULTS

Forty-one children were enrolled and 92 assessments (ranging from one to four per subject) were completed. Congenital heart disease patients accounted for 73 enrollees (79%). Forty-three percent of observations were performed in children on invasive mechanical ventilation. Pediatric delirium prevalence (as determined by psychiatric diagnosis) was 53%. The Japanese version of the Cornell Assessment of Pediatric Delirium demonstrated an optimal scoring cutpoint of 9. Overall, area under the curve was 92%, sensitivity 90% (95% CI, 79-97%), specificity 88% (95% CI, 75-96%), positive predictive value of 90% (95% CI, 79-97%), negative predictive value of 91% (95% CI, 80-97%), and a Cohen's κ of 0.89 (95% CI, 0.8-0.98). In children on invasive mechanical ventilation, the Japanese version of the Cornell Assessment of Pediatric Delirium maintained an area under the curve 87%, sensitivity 97%, and specificity 64%.

CONCLUSIONS

The Japanese version of the Cornell Assessment of Pediatric Delirium is a valid and reliable tool for use in Japanese PICUs. This will allow for detection of delirium in real-time and may lead to better identification of the population and risk factors for appropriate management and therapeutic and preventative interventions.

Evaluation of an updated sedation protocol to reduce benzodiazepines in a pediatric intensive care unit

Aim: Midazolam like other benzodiazepines is supposed to be neurotoxic in small children and to represent a risk factor for the development of delirium. The aim of this study was to evaluate whether a modified analgesia and sedation protocol is feasible and effective to reduce the requirement of midazolam in neonates and young infants after cardiac surgery.Methods: Patients aged 6 months or younger who underwent surgery for congenital heart disease with cardiopulmonary bypass were enrolled and divided into a pre-modification group (January-December 2016) and after adjusting our sedation protocol into a post-modification group (January-December 2018). We assessed the doses of midazolam, morphine and clonidine as well as sedation scores according to our nurse-driven sedation protocol every 8 h until 120 h after cardiac surgery. During weaning from analgesia and sedation, children were monitored regarding withdrawal symptoms and pediatric delirium.Results: Sixty-five patients were included (33 patients in the pre-modification group, 32 patients in the post-modification group). The number of patients receiving midazolam and the cumulative dose of midazolam could be successfully reduced. The sedation scores were still within the desired target range for adequate sedation without any negative side effects.Conclusions: It is feasible and safe to reduce the use of midazolam in infants after cardiac surgery maintaining sedation goals based on a modified nurse-driven analgesia and sedation protocol.

Validation of the SOS-PD scale for assessment of pediatric delirium: a multicenter study

Backgrounds

Reports of increasing incidence rates of delirium in critically ill children are reason for concern. We evaluated the measurement properties of the pediatric delirium component (PD-scale) of the Sophia Observation Withdrawal Symptoms scale Pediatric Delirium scale (SOS-PD scale).

Methods

In a multicenter prospective observational study in four Dutch pediatric ICUs (PICUs), patients aged ≥ 3 months and admitted for ≥ 48 h were assessed with the PD-scale thrice daily. Criterion validity was assessed: if the PD-scale score was ≥ 4, a child psychiatrist clinically assessed the presence or absence of PD according to the Diagnostic and statistical manual of mental disorders (DSM)-IV. In addition, the child psychiatrist assessed a randomly selected group to establish the false-negative rate. The construct validity was assessed by calculating the Pearson coefficient (r_p) for correlation between the PD-scale and Cornell Assessment Pediatric Delirium (CAP-D) scores. Interrater reliability was determined by comparing paired nurse-researcher PD-scale assessments and calculating the intraclass correlation coefficient (ICC).

Results

Four hundred eighty-five patients with a median age of 27.0 months (IQR 8–102) were included, of whom 48 patients were diagnosed with delirium by the child psychiatrist. The PD-scale had overall sensitivity of 92.3% and specificity of 96.5% compared to the psychiatrist diagnosis for a cutoff score ≥4 points. The r_p between the PD-scale and the CAP-D was 0.89 (CI 95%, 0.82–0.93; p < 0.001). The ICC of 75 paired nurse-researcher observations was 0.99 (95% CI, 0.98–0.99).

Conclusions

The PD-scale has good reliability and validity for early screening of PD in critically ill children. It can be validly and reliably used by nurses to this aim.

Translation and cross-cultural adaptation of the Pediatric Confusion Assessment Method for the Intensive Care Unit into Brazilian Portuguese for the detection of delirium in pediatric intensive care units

Objective

To undertake the translation and cross-cultural adaption into Brazilian Portuguese of the Pediatric Confusion Assessment Method for the Intensive Care Unit for the detection of delirium in pediatric intensive care units, including the algorithm and instructions.

Methods

A universalist approach for the translation and cross-cultural adaptation of health measurement instruments was used. A group of pediatric critical care specialists assessed conceptual and item equivalences. Semantic equivalence was evaluated by means of a translation from English to Portuguese by two independent translators; reconciliation into a single version; back-translation by a native English speaker; and consensus among six experts with respect to language and content understanding by means of Likert scale responses and the Content Validity Index. Finally, operational equivalence was assessed by applying a pre-test to 30 patients.

Results

The back-translation was approved by the original authors. The medians of the expert consensus responses varied between good and excellent, except for the feature "acute onset" of the instructions. Items with a low Content Validity Index for the features "acute onset" and "disorganized thinking" were adapted. In the pre-test, the expression "signal with your head" was modified into "nod your head" for better understanding. No further adjustments were necessary, resulting in the final version for Brazilian Portuguese.

Conclusion

The Brazilian version of the Pediatric Confusion Assessment Method for the Intensive Care Unit was generated in agreement with the international recommendations and can be used in Brazil for the diagnosis of delirium in critically ill children 5 years of age or above and with no developmental cognitive disabilities.

Sleep and Delirium in Pediatric Critical Illness: What Is the Relationship?

With growing recognition of pediatric delirium in pediatric critical illness there has also been increased investigation into improving recognition and determining potential risk factors. Disturbed sleep has been assumed to be one of the key risk factors leading to delirium and is commonplace in the pediatric critical care setting as the nature of intensive care requires frequent and invasive monitoring and interventions. However, this relationship between sleep and delirium in pediatric critical illness has not been definitively established and may, instead, reflect significant overlap in risk factors and consequences of underlying neurologic dysfunction. We aim to review the existing tools for evaluation of sleep and delirium in the pediatric critical care setting and review findings from recent investigations with application of these measures in the pediatric intensive care unit.

Intravenous morphine versus intravenous paracetamol after cardiac surgery in neonates and infants: a study protocol for a randomized controlled trial

BACKGROUND

Morphine is worldwide the analgesic of first choice after cardiac surgery in children. Morphine has unwanted hemodynamic and respiratory side effects. Therefore, post-cardiac surgery patients may potentially benefit from a non-opioid drug for pain relief. A previous study has shown that intravenous (IV) paracetamol is effective and opioid-sparing in children after major non-cardiac surgery. The aim of the study is to test the hypothesis that intermittent IV paracetamol administration in children after cardiac surgery will result in a reduction of at least 30% of the cumulative morphine requirement.

METHODS

This is a prospective, multi-center, randomized controlled trial at four level-3 pediatric intensive care units (ICUs) in the Netherlands and Belgium. Children who are 0-36 months old will be randomly assigned to receive either intermittent IV paracetamol or continuous IV morphine up to 48 h post-operatively. Morphine will be available as rescue medication for both groups. Validated pain and sedation assessment tools will be used to monitor patients. The sample size (n = 208, 104 per arm) was calculated in order to detect a 30% reduction in morphine dose; two-sided significance level was 5% and power was 95%.

DISCUSSION

This study will focus on the reduction, or replacement, of morphine by IV paracetamol in children (0-36 months old) after cardiac surgery. The results of this study will form the basis of a new pain management algorithm and will be implemented at the participating ICUs, resulting in an evidence-based guideline on post-operative pain after cardiac surgery in infants who are 0-36 months old.
