Abstract
Delirium has long been recognized within the adult intensive care world, but it is only within the past decade that its presence and prevalence in the context of pediatric intensive care has been studied. There is now a greater understanding of risk factors for delirium, a better selection of methods to recognize it, and treatment specifically directed to pediatric patients. An understanding of delirium is also relevant to pediatricians practicing outside of the intensive care unit, as delirium can present in other care environments, where it remains under-recognized. The purpose of this article is to review pediatric delirium by discussing its pathophysiology, the tools available to screen patients, and current prevention and management approaches.

Abstract
INTRODUCTION Delirium is one of the most common forms of acute cerebral dysfunction in critically ill children leading to increased morbidity and mortality. Prevention, identification and management of delirium is an important part of paediatric and neonatological intensive care. This scoping review aims to identify and map evidence on non-pharmacological interventions for paediatric delirium prevention and management in paediatric and neonatal intensive care settings. METHODS AND ANALYSIS This scoping review will be conducted according to the Joanna Briggs Institute methodology for scoping reviews and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Searches will be performed in the databases Medline (via PubMed), CINAHL, Cochrane Library, Ovid (Journals), EMBASE and Web of Science (01/2000-current). Two reviewers will independently review retrieved studies, and relevant information will be extracted using data extraction forms. The results will be presented in tabular format and accompanied by a narrative summary. INCLUSION CRITERIA The review will include references that describe or evaluate non-pharmacological interventions to prevent or manage paediatric delirium. Conference abstracts, editorials, opinion papers and grey literature will be excluded. ETHICS AND DISSEMINATION Due to the nature of research involving humans or unpublished secondary data, approval of an ethics committee are not required. The dissemination of findings is planned via professional networks and publication in an open-access scientific journal.

Abstract
BACKGROUND Delirium is a common occurrence in medically compromised adults, but, research is limited in the pediatric population especially from low- and middle-income countries such as India. AIMS This study aimed to evaluate the emergence of delirium in children aged 5-18 years admitted to a pediatric intensive care unit (PICU) of a tertiary care hospital in North India. Other objectives included delineating the clinical characteristics of delirium and its clinical correlates. METHODOLOGY It was a prospective cohort study in which all admitted children during a calendar year were assessed and those fulfilling the inclusion criteria were enrolled for study. The Pediatric Confusion Assessment Method Intensive Care Unit (p-CAM-ICU) scale was used to diagnose delirium. RESULTS ut of 305 total admissions to the PICU, 105 children were included. More than two third were male (68.6%) with a median age of 11 years. The incidence of delirium was 11.4% and median duration of delirium was 2 days. Majority of the children had hypoactive delirium (58.3%), followed by hyperactive (25%) and mixed type (16.7%). Metabolic or respiratory acidosis at baseline was significantly associated with delirium (p = 0.030). Presence of delirium led to significant prolongation of PICU stay (p < 0.001). CONCLUSION The emergence of delirium elicited in this study is on the lower side incomparison to previous studies. Several etiological factors for delirium are preventable and hence protocols and guidelines for management are required.

Abstract
Delirium is the most common psychiatric diagnoses encountered in patients with various medical-surgical illnesses, in all the treatment set-ups, with relatively higher incidence and prevalence in the intensive care units. As delirium is encountered in multiple specialties, it is important to understand the research on this diagnosis. This study aims to assess the research output involving patients of delirium from India. A comprehensive search was undertaken using Medline (PubMed) and other databases. Search words included were “delirium,” “delirious,” “delirium tremens” AND “India.” No filters were used. Internet and hand searches yielded 305 articles. Out of these articles, 151 had the terms “delirium,” “delirious,” “delirium tremens” in the title and these were included for the review. Additionally, 14 articles were included for the review, although these did not have these terms in the title, but delirium was one of the major outcome parameters in these studies. Majority of the papers were original articles (
n
= 81), and these were followed by, case reports (
n
= 58), review articles (
n
= 10), letter to the editor (not as case reports but as a communication;
n
= 13), editorials (
n
= 2) and one clinical practice guideline. Most of the original papers have either focused on epidemiology (incidence, prevalence, outcome, etc.), symptom profile, with occasional studies focusing on effectiveness of various pharmacological interventions. There is a dearth of research in the field of delirium from India. There is a lack of studies on biomarkers, evaluation of nonpharmacological interventions, and evaluation of prevention strategies. It is the need of the hour to carry out more studies to further our understanding of delirium in the Indian context.

Abstract
PURPOSE OF REVIEW Delirium is a frequent complication of serious medical illness in children. The purpose of this review is to highlight recent data on the epidemiology and outcomes related to pediatric delirium, and discuss prevention strategies. RECENT FINDINGS Delirium rates in the pediatric ICU are greater than 25%. Delirium in children is associated with prolonged mechanical ventilation and hospital length of stay, increased costs, and excess mortality. Pediatric delirium may affect postdischarge cognition and quality of life. Recent initiatives targeting universal screening, early mobilization, and minimization of benzodiazepine-based sedation have shown reduction in delirium prevalence. SUMMARY Widespread screening is needed in critically ill children to detect and mitigate delirium. The identification of modifiable risk factors has provided an opportunity for delirium prevention. Large-scale longitudinal studies are needed to investigate the long-term sequelae of delirium in children.

Abstract
Introduction Pediatric delirium is a significant problem when encounterd in an intensive care unit (ICU). The pathophysiology of pediatric delirium is complex and the etiology is typically multifactorial. Even though various risk factors associated with pediatric delirium in a pediatric ICU have been identified, there is still a paucity of literature associated with the condition, especially in extremely critically ill children, sedated and mechanically ventilated. Aim of the study To identify factors associated with delirium in mechanically ventilated children in an ICU. Material and Methods This is a single-center study conducted at a tertiary care pediatric ICU. Patients admitted to the pediatric ICU requiring sedation and mechanical ventilation for >48 hours were included. Cornell Assessment of Pediatric Delirium scale was used to screen patients with delirium. Baseline demographic and clinical factors as well as daily and cumulative doses of medications were compared between patients with and without delirium. Firth’s penalized maximum likelihood logistic regression was used on a priori set of variables to examine the association of potential factors with delirium. Two regression models were created to assess the effect of daily medication doses (Model 1) as well as cumulative medication doses (Model 2) of opioids and benzodiazepines. Results 95 patient visits met the inclusion criteria. 19 patients (20%) were diagnosed with delirium. Older patients (>12 years) had higher odds of developing delirium. Every 1mg/kg/day increase in daily doses of opioids was associated with an increased risk of delirium (OR=1.977, p=0.017). Likewise, 1 mg/kg increase in the cumulative opioid dose was associated with a higher odds of developing delirium (OR=1.035, p=0.022). Duration of mechanical ventilation was associated with the development of delirium in Model 1 (p=0.007). Conclusions Age, daily and cumulative opioid dosage and the duration of mechanical ventilation are associated with the development of delirium in mechanically ventilated children.

Abstract
OBJECTIVE The diagnosis of delirium depends on eliciting its features through mental status examination and informant history. However, there is marked heterogeneity in how these features are assessed, from binary subjective clinical judgement to more comprehensive methods supported by cognitive testing. The aim of this article is to review the neuropsychological research in delirium and suggest future directions in research and clinical practice. METHODS We reviewed the neuropsychological literature on formal assessment and quantification of the different domains in delirium, focusing on the core feature of inattention. RESULTS Few studies have characterised and quantified the features of delirium using objective methods commonly employed in neuropsychological research. The existing evidence confirms that patients with delirium usually show impairments on objective tests of attention compared with cognitively intact controls and, in most cases, compared with patients with dementia. Further, abnormal level of arousal appears to be a specific indicator of delirium. The neuropsychological evidence base for impairments in other cognitive domains in delirium, including visual perception, language and thought processes, is small. CONCLUSIONS Delirium diagnosis requires accurate testing for its features, but there is little neuropsychological research examining the nature of these features, or evaluating the reliability, validity and discriminatory power of existing assessment processes. More research using the neuropsychological approach has enormous potential to improve and standardise delirium assessment methods of the individual features of delirium, such as inattention, and in developing more robust reference standards to enable greater comparability between studies.

Abstract
CONTEXT Fluctuation in symptoms is a core feature of delirium. However, it is not well known whether the fluctuating nature would differ or not among the delirium subtype groups. OBJECTIVE This study compared phenotypes of diurnal fluctuation among different delirium subtypes using a prospective design. METHODS The motor subtypes of delirium patients were determined using the Delirium Motor Subtype Scale, fluctuations in consciousness levels were monitored with the Richmond Agitation-Sedation Scale (RASS), and symptom severity was assessed with the Nursing Delirium Screening Scale (Nu-DESC). All scales were administered at three time points over 24 hours; fluctuations in and phenotypes of symptoms were compared according to subtype of delirium using repeated-measures analysis of variance after adjustment for covariates. RESULTS This study included 224 delirium patients. Of this patients, 144 (64.3%) were classified as hyperactive, 25 (11.2%) as hypoactive, 33 (14.7%) as mixed, and 22 (9.9%) as no subtype. Scores on the RASS and Nu-DESC significantly changed during the evening and/or night and there were significant subtype group × time interaction for the RASS and Nu-DESC (F = 9.66, P < 0.001 and F = 5.11, P < 0.001, respectively). Post hoc analyses revealed that the hyperactive and mixed subtype groups had higher mean RASS scores and greater ranges of fluctuation than the other groups. The mixed subtype group was differentiated from hyperactive and hypoactive subtype groups by the range of fluctuation in psychomotor activity. CONCLUSIONS The phenotypes of symptom fluctuation differed among the motor subtypes. These findings further support the rationale that fluctuations are a core feature of delirium and could differentiate delirium subtypes.

Abstract
: Purpose: The purpose of this study was to examine the evidence regarding the risk factors for and characteristics of acute pediatric delirium in hospitalized children. METHODS The systematic review method within an epidemiological framework of person, place, and time was used. Fifty-two studies were selected for initial retrieval. Of these, after assessment for methodological quality, 21 studies involving 2,616 subjects were included in the review. RESULTS Findings revealed five primary characteristics seen in children experiencing delirium: agitation, disorientation, hallucinations, inattention, and sleep-wake cycle disturbances. Children who were more seriously ill, such as those in a pediatric ICU (PICU) and those with a high Pediatric Risk of Mortality II (PRISM II) score, and children who were mechanically ventilated were at greater risk for development of delirium. Those with a developmental delay or a preexisting anxiety disorder were also more prone to delirium. Although delirium symptoms fluctuate, most episodes occurred at night. Boys were slightly more susceptible than girls, though this difference was not significant. A key finding of this review was that delirium is multifactorial, related to treatment (mechanical ventilation, for example) and to a hospital environment (such as a PICU) that deprives patients of normal sleep-wake cycles and familiar routines. CONCLUSION These findings will be useful in efforts to achieve earlier recognition and better management or prevention of pediatric delirium. This may also help to prevent unnecessary laboratory testing and imaging studies, which can cause children and parents unnecessary pain and anxiety and increase hospital costs.

Abstract
INTRODUCTION Clinical motor subtypes have been long recognised in delirium and, despite a growing body of research, a lack of clarity exists regarding the importance of these motor subtypes. The aims of this review are to (1) examine how the concept of motor subtypes has evolved, (2) explore their relationship to the clinical context, (3) discuss the relationship between the phenomenology of delirium and motor activity, (4) discuss the application of neurobiology to the theory of delirium motor subtypes, and (5) identify methodological issues and provide solutions for further studies. METHODS The following databases were searched: PubMed, PsychInfo, EBSCO, Medline, BioMed central and Science Direct. Inclusion criteria specified peer-reviewed research assessing delirium motor subtypes published between 1990 and 2016. RESULTS Sixty-one studies met the inclusion criteria. The majority of studies (n = 50) were found to use validated psychometric tools, while the remainder (n = 11) used clinical criteria. The majority of studies (n = 45) were conducted in the medical setting, while the remainder were in the ICU/post-operative setting (n = 17). CONCLUSION Although host sensitivities (e.g. frailty) and exogenous factors (e.g. medication exposure) may determine the type of motor disturbance, it remains unclear to what extent motor subtypes are influenced by other features of delirium. The use of more specialised tools (e.g. delirium motor subtyping scale), may enable researchers to develop an approach to delirium that has a greater nosological consistency. Future studies investigating delirium motor subtypes may benefit from enhanced theoretical considerations of the dysfunctional neural substrate of the delirious state.

Abstract
PURPOSE OF REVIEW This review seeks to provide an update on the diagnosis, management, and outcome of pediatric delirium. RECENT FINDINGS Care of patients with delirium depends on correct diagnosis and treatment of its underlying cause. A variety of instruments are available to aid diagnosis. Management of delirium currently depends on atypical antipsychotics, while avoiding agents that may precipitate or exacerbate it. While most critically ill children survive delirium, many children die or have worsening function after their illness. The longer the duration of delirium, the more severe its subsequent problems including postintensive care syndrome and posttraumatic stress disorder. Possible serious long-term consequences emphasize the importance of efforts to improve diagnosis and outcome in critically ill children suffering from delirium.

Abstract
PURPOSE/OBJECTIVE The purposes of this article are to describe the scientific literature on assessment, prevention, and management of delirium in critically ill children and to articulate the implications for clinical nurse specialists, in translating the evidence into practice. DESCRIPTION A literature search was conducted in 4 databases-OvidMEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsychINFO, and Web of Science-using the terms "delirium," "child," and "critically ill" for the period of 2006 to 2016. OUTCOME The scientific literature included articles on diagnosis, prevalence, risk factors, adverse outcomes, screening tools, prevention, and management. The prevalence of delirium in critically ill children is up to 30%. Risk factors include age, developmental delay, severity of illness, and mechanical ventilation. Adverse outcomes include increased mortality, hospital length of stay, and cost for the critically ill child with delirium. Valid and reliable delirium screening tools are available for critically ill children. Prevention and management strategies include interventions to address environmental triggers, sleep disruption, integrated family care, and mobilization. CONCLUSION Delirium is a common occurrence for the critically ill child. The clinical nurse specialist is accountable for leading the implementation of practice changes that are based on evidence to improve patient outcomes. Screening and early intervention for delirium are key to mitigating adverse outcomes for critically ill children.

Abstract
OBJECTIVES To identify available assessment tools for sedative/hypnotic iatrogenic withdrawal syndrome and delirium in PICU patients, the evidence supporting their use, and describe areas of overlap between the components of these tools and the symptoms of anticholinergic burden in children. DATA SOURCES Studies were identified using PubMed and EMBASE from the earliest available date until July 3, 2016, using a combination of MeSH terms "delirium," "substance withdrawal syndrome," and key words "opioids," "benzodiazepines," "critical illness," "ICU," and "intensive care." Review article references were also searched. STUDY SELECTION Human studies reporting assessment of delirium or iatrogenic withdrawal syndrome in children 0-18 years undergoing critical care. Non-English language, exclusively adult, and neonatal intensive care studies were excluded. DATA EXTRACTION References cataloged by study type, population, and screening process. DATA SYNTHESIS Iatrogenic withdrawal syndrome and delirium are both prevalent in the PICU population. Commonly used scales for delirium and iatrogenic withdrawal syndrome assess signs and symptoms in the motor, behavior, and state domains, and exhibit considerable overlap. In addition, signs and symptoms of an anticholinergic toxidrome (a risk associated with some common PICU medications) overlap with components of these scales, specifically in motor, cardiovascular, and psychiatric domains. CONCLUSIONS Although important studies have demonstrated apparent high prevalence of iatrogenic withdrawal syndrome and delirium in the PICU population, the overlap in these scoring systems presents potential difficulty in distinguishing syndromes, both clinically and for research purposes.

Abstract
Delirium is a serious and common problem in severely medically ill patients of all ages. It has been less addressed in children and adolescents. Treatment of delirium is predicated on addressing its underlying cause. The management of its symptoms depends on the off-label use of antipsychotics, while avoiding agents that precipitate or worsen delirium. Olanzapine, quetiapine, and risperidone are presently considered first-line drugs, usually replacing haloperidol. Other agents have shown promise, including melatonin to address the sleep disturbance characteristic of delirium, and dexmedetomidine, an α2-agonist, that may facilitate lower doses of benzodiazepines and opioids that may worsen delirium.
