Parents and caregivers of children with cancer are both resilient and deeply affected by the child's cancer. A systematic review of published research since 1995 identified 138 studies of moderate quality indicating that parent distress increases around diagnosis, then returns to normal levels. Posttraumatic symptoms are common. Distress may be impairing for vulnerable parents and may impact a child's coping and adjustment. Moderate quality evidence and expert consensus informed a strong recommendation for parents and caregivers to receive early and ongoing assessment of their mental health needs with access to appropriate interventions facilitated to optimize parent, child and family well-being.

Objective To determine validity and reliability of the Cornell Assessment of Pediatric Delirium, a rapid observational screening tool. Design Double-blinded assessments were performed with the Cornell Assessment of Pediatric Delirium completed by nursing staff in the PICU. These ratings were compared with an assessment by consultation liaison child psychiatrist using the Diagnostic and Statistical Manual IV criteria as the “gold standard” for diagnosis of delirium. An initial series of duplicate Cornell Assessment of Pediatric Delirium assessments were performed in blinded fashion to assess interrater reliability. Nurses recorded the time required to complete the Cornell Assessment of Pediatric Delirium screen. Setting Twenty-bed general PICU in a major urban academic medical center over a 10-week period, March–May 2012. Patients One hundred eleven patients stratified over ages ranging from 0 to 21 years and across developmental levels. Intervention Two hundred forty-eight paired assessments completed. Measurements and Main Results The Cornell Assessment of Pediatric Delirium had an overall sensitivity of 94.1% (95% CI, 83.8–98.8%) and specificity of 79.2% (95% CI, 73.5–84.9%). Overall Cronbach’s α of 0.90 was observed, with a range of 0.87–0.90 for each of the eight items, indicating good internal consistency. A scoring cut point of 9 demonstrated good interrater reliability of the Cornell Assessment of Pediatric Delirium when comparing results of the screen between nurses (overall κ = 0.94; item range κ = 0.68–0.78). In patients without significant developmental delay, sensitivity was 92.0% (95% CI, 85.7–98.3%) and specificity was 86.5% (95% CI, 75.4–97.6%). In developmentally delayed children, the Cornell Assessment of Pediatric Delirium showed decreased specificity of 51.2% (95% CI, 24.7–77.8%) but sensitivity remained high at 96.2% (95% CI, 86.5–100%). The Cornell Assessment of Pediatric Delirium takes less than 2 minutes to complete. Conclusions With an overall prevalence rate of 20.6% in our study population, delirium is a common problem in pediatric critical care. The Cornell Assessment of Pediatric Delirium is a valid, rapid, observational nursing screen that is urgently needed for the detection of delirium in PICU settings.

The CAP-D may be a valid screen for identification of delirium in PICU patients of all ages. Further studies are required to explore its validity, inter-rater reliability, and feasibility of use as a nursing screen.

Objective To describe a single-institution pilot study regarding prevalence and risk factors for delirium in critically ill children. Design A prospective observational study, with secondary analysis of data collected during the validation of a pediatric delirium screening tool, the Cornell Assessment of Pediatric Delirium (CAPD). Setting This study took place in the pediatric intensive care unit (PICU) at an urban academic medical center. Patients 99 consecutive patients, ages newborn to 21 years. Intervention Subjects underwent a psychiatric evaluation for delirium based on the DSM-IV criteria. Measurements and Main Results Prevalence of delirium in this sample was 21%. In multivariate analysis, risk factors associated with the diagnosis of delirium were presence of developmental delay, need for mechanical ventilation, and age 2-5 years. Conclusions In our institution, pediatric delirium is a prevalent problem, with identifiable risk factors. Further large-scale prospective studies are required to explore multi-institutional prevalence, modifiable risk factors, therapeutic interventions, and effect on long-term outcomes.

Objective The recently validated Cornell Assessment for Pediatric Delirium (CAPD) is a new rapid bedside nursing screen for delirium in hospitalized children of all ages. The present manuscript provides a “developmental anchor points” reference chart, which helps ground clinicians’ assessment of CAPD symptom domains in a developmental understanding of the presentation of delirium. Method During the development of this CAPD screening tool, it became clear that clinicians need specific guidance and training to help them draw on their expertise in child development and pediatrics to improve the interpretative reliability of the tool and its accuracy in diagnosing delirium. The developmental anchor points chart was formulated and reviewed by a multidisciplinary panel of experts to evaluate content validity and include consideration of sick behaviors within a hospital setting. Results The CAPD developmental anchor points for the key ages of newborn, 4 weeks, 6 weeks, 8 weeks, 28 weeks, 1 year, and 2 years served as the basis for training bedside nurses in scoring the CAPD for the validation trial and as a multifaceted bedside reference chart to be implemented within a clinical setting. In the current paper, we discuss the lessons learned during implementation, with particular emphasis on the importance of collaboration with the bedside nurse, the challenges of establishing a developmental baseline, and further questions about delirium diagnosis in children. Significance of Results The CAPD with developmental anchor points provides a validated, structured, and developmentally informed approach to screening and assessment of delirium in children. With minimal training on the use of the tool, bedside nurses and other pediatric practitioners can reliably identify children at risk for delirium.
