Measuring Social Health Following Pediatric Critical Illness: A Scoping Review and Conceptual Framework.

OBJECTIVE: Social health is an important component of recovery following critical illness as modeled in the pediatric Post-Intensive Care Syndrome framework. We conducted a scoping review of studies measuring social outcomes (measurable components of social health) following pediatric critical illness and propose a conceptual framework of the social outcomes measured in these studies. DATA SOURCES: PubMed, EMBASE, PsycINFO, CINAHL, and the Cochrane Registry. STUDY SELECTION: We identified studies evaluating social outcomes in pediatric intensive care unit (PICU) survivors or their families from 1970-2017 as part of a broader scoping review of outcomes after pediatric critical illness. DATA EXTRACTION: We identified articles by dual review and dual-extracted study characteristics, instruments, and instrument validation and administration information. For instruments used in studies evaluating a social outcome, we collected instrument content and described it using qualitative methods adapted to a scoping review. DATA SYNTHESIS: Of 407 articles identified in the scoping review, 223 (55%) evaluated a social outcome. The majority were conducted in North America and the United Kingdom, with wide variation in methodology and population. Among these studies, 38 unique instruments were used to evaluate a social outcome. Specific social outcomes measured included individual (independence, attachment, empathy, social behaviors, social cognition, and social interest), environmental (community perceptions and environment), and network (activities and relationships) characteristics, together with school and family outcomes. While many instruments assessed more than one social outcome, no instrument evaluated all areas of social outcome. CONCLUSIONS: The full range of social outcomes reported following pediatric critical illness were not captured by any single instrument. The lack of a comprehensive instrument focused on social outcomes may contribute to under-appreciation of the importance of social outcomes and their under-representation in PICU outcomes research. A more comprehensive evaluation of social outcomes will improve understanding of overall recovery following pediatric critical illness.

Effectiveness of a One Day Self-Compassion Training for Pediatric Nurses' Resilience.

BACKGROUND: Resilience is a critical skill for nurses and other healthcare professionals, especially during the COVID-19 pandemic, yet few nurses receive training that promotes emotional awareness and regulation, resilience, and self-compassion. PURPOSE: The purpose of this study was to understand if attending a one-day workshop format of the Self Compassion for Healthcare Communities (SCHC) program would improve pediatric nurses' resilience, well-being, and professional quality of life. DESIGN AND METHODS: Following a quasi-experimental design, pre, post, and follow-up surveys were acquired from 22 nurses who attended the training and 26 nurses who did not attend the training. In a linear mixed models regression analysis, changes in self-compassion, mindfulness, compassion, resilience, job engagement, professional quality of life (compassion satisfaction, burnout, and secondary traumatic stress), depression, anxiety and stress were analyzed between groups. RESULTS: Participants in the intervention exhibited significant increases in self-compassion, mindfulness, compassion to others, resilience and compassion satisfaction, and significant decreases in burnout, anxiety, and stress compared to the non-intervention group. CONCLUSIONS: A one-day SCHC training program provides nurses with knowledge and skills to increase their resilience and support their emotional well-being and professional quality of life. PRACTICE IMPLICATIONS: Nurses' schedules may hamper their ability to attend lengthy resilience trainings, yet the skills needed for resilience are crucial to decreasing burnout, empathy fatigue, and turnover. Offering an effective, one-day training provides an accessible alternative for nurses to gain knowledge and skills that increase resilience.

Postdischarge Outcome Domains in Pediatric Critical Care and the Instruments Used to Evaluate Them: A Scoping Review.

OBJECTIVES: Assessing outcomes after pediatric critical illness is imperative to evaluate practice and improve recovery of patients and their families. We conducted a scoping review of the literature to identify domains and instruments previously used to evaluate these outcomes. DESIGN: Scoping review. SETTING: We queried PubMed, EMBASE, PsycINFO, Cumulative Index of Nursing and Allied Health Literature, and the Cochrane Central Register of Controlled Trials Registry for studies evaluating pediatric critical care survivors or their families published between 1970 and 2017. We identified articles using key words related to pediatric critical illness and outcome domains. We excluded articles if the majority of patients were greater than 18 years old or less than 1 month old, mortality was the sole outcome, or only instrument psychometrics or procedural outcomes were reported. We used dual review for article selection and data extraction and categorized outcomes by domain (overall health, emotional, physical, cognitive, health-related quality of life, social, family). SUBJECTS: Manuscripts evaluating outcomes after pediatric critical illness. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 60,349 citations, 407 articles met inclusion criteria; 87% were published after 2000. Study designs included observational (85%), interventional (7%), qualitative (5%), and mixed methods (3%). Populations most frequently evaluated were traumatic brain injury (n = 96), general pediatric critical illness (n = 87), and congenital heart disease (n = 72). Family members were evaluated in 74 studies (18%). Studies used a median of 2 instruments (interquartile range 1-4 instruments) and evaluated a median of 2 domains (interquartile range 2-3 domains). Social (n = 223), cognitive (n = 183), and overall health (n = 161) domains were most frequently studied. Across studies, 366 unique instruments were used, most frequently the Wechsler and Glasgow Outcome Scales. Individual domains were evaluated using a median of 77 instruments (interquartile range 39-87 instruments). CONCLUSIONS: A comprehensive, generalizable understanding of outcomes after pediatric critical illness is limited by heterogeneity in methodology, populations, domains, and instruments. Developing assessment standards may improve understanding of postdischarge outcomes and support development of interventions after pediatric critical illness.

Predictors of Traumatic Suicide Attempts in Youth Presenting to Hospitals with Level I Trauma Centers.

BACKGROUND: Limited research exists examining the predictors of suicide attempts by mechanism. OBJECTIVE: The purpose of this study was to examine predictors of traumatic suicide attempts in youth. METHODS: Data came from patients 5-18 years of age presenting because of a suicide attempt at 2 hospitals in Central Texas with level I trauma centers. Univariate logistic regression examined the association between traumatic suicide attempts and variables describing the patient's demographic, mental health, and social information. We used the Mann-Whitney U test to examine the association between traumatic suicide attempts and the continuous variable of age. RESULTS: Of 231 patients included in this study, most were female (75.8%), non-Hispanic white (48.1%), and had a median age of 15.0 years (interquartile range 14-16). Compared with patients presenting because of an intentional overdose, patients presenting because of traumatic suicide attempts were associated with a reported criminal history (odds ratio [OR] 14.50 [95% confidence interval {CI} 3.84-54.82]), reported Child Protective Services history (OR 3.26 [95% CI 0.99-10.77]), being publicly insured or uninsured (OR 1.80 [95% CI 1.02-3.19]), male (OR 2.37 [95% CI 1.28-4.38]), and identifying as Hispanic (OR 2.01 [95% CI 1.10-3.68). CONCLUSIONS: Our findings inform targeted preventative resources and education efforts to populations of greatest need.

Growth and Changing Characteristics of Pediatric Intensive Care 2001-2016.

OBJECTIVES: We assessed the growth, distribution, and characteristics of pediatric intensive care in 2016. DESIGN: Hospitals with PICUs were identified from prior surveys, databases, online searching, and clinician networking. A structured web-based survey was distributed in 2016 and compared with responses in a 2001 survey. SETTING: PICUs were defined as a separate unit, specifically for the treatment of children with life-threatening conditions. PICU hospitals contained greater than or equal to 1 PICU. SUBJECTS: Physician medical directors and nurse managers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: PICU beds per pediatric population (< 18 yr), PICU bed distribution by state and region, and PICU characteristics and their relationship with PICU beds were measured. Between 2001 and 2016, the U.S. pediatric population grew 1.9% to greater than 73.6 million children, and PICU hospitals decreased 0.9% from 347 to 344 (58 closed, 55 opened). In contrast, PICU bed numbers increased 43% (4,135 to 5,908 beds); the median PICU beds per PICU hospital rose from 9 to 12 (interquartile range 8, 20 beds). PICU hospitals with greater than or equal to 15 beds in 2001 had significant bed growth by 2016, whereas PICU hospitals with less than 15 beds experienced little average growth. In 2016, there were eight PICU beds per 100,000 U.S. children (5.7 in 2001), with U.S. census region differences in bed availability (6.8 to 8.8 beds/100,000 children). Sixty-three PICU hospitals (18%) accounted for 47% of PICU beds. Specialized PICUs were available in 59 hospitals (17.2%), 48 were cardiac (129% growth). Academic affiliation, extracorporeal membrane oxygenation availability, and 24-hour in-hospital intensivist staffing increased with PICU beds per hospital. CONCLUSIONS: U.S. PICU bed growth exceeded pediatric population growth over 15 years with a relatively small percentage of PICU hospitals containing almost half of all PICU beds. PICU bed availability is variable across U.S. states and regions, potentially influencing access to care and emergency preparedness.

Models of Peer Support to Remediate Post-Intensive Care Syndrome: A Report Developed by the Society of Critical Care Medicine Thrive International Peer Support Collaborative.

OBJECTIVES: Patients and caregivers can experience a range of physical, psychologic, and cognitive problems following critical care discharge. The use of peer support has been proposed as an innovative support mechanism. DESIGN: We sought to identify technical, safety, and procedural aspects of existing operational models of peer support, among the Society of Critical Care Medicine Thrive Peer Support Collaborative. We also sought to categorize key distinctions between these models and elucidate barriers and facilitators to implementation. SUBJECTS AND SETTING: Seventeen Thrive sites from the United States, United Kingdom, and Australia were represented by a range of healthcare professionals. MEASUREMENTS AND MAIN RESULTS: Via an iterative process of in-person and email/conference calls, members of the Collaborative defined the key areas on which peer support models could be defined and compared, collected detailed self-reports from all sites, reviewed the information, and identified clusters of models. Barriers and challenges to implementation of peer support models were also documented. Within the Thrive Collaborative, six general models of peer support were identified: community based, psychologist-led outpatient, models-based within ICU follow-up clinics, online, groups based within ICU, and peer mentor models. The most common barriers to implementation were recruitment to groups, personnel input and training, sustainability and funding, risk management, and measuring success. CONCLUSIONS: A number of different models of peer support are currently being developed to help patients and families recover and grow in the postcritical care setting.

Peer Support as a Novel Strategy to Mitigate Post-Intensive Care Syndrome.

Post-intensive care syndrome, a condition defined by new or worsening impairment in cognition, mental health, and physical function after critical illness, has emerged in the past decade as a common and life-altering consequence of critical illness. New strategies are urgently needed to mitigate the risk of neuropsychological and functional impairment common after critical illness and to prepare and support survivors on their road toward recovery. The present state of critical care survivorship is described, and postdischarge care delivery in the United States and the potential impact of the present-day fragmented model of care delivery are detailed. A novel strategy that uses peer support groups could more effectively meet the needs of survivors of critical illness and mitigate post-intensive care syndrome.

Potential Impact of a Validated Screening Tool for Pediatric Abusive Head Trauma.

OBJECTIVE: To conduct a retrospective, theoretical comparison of actual pediatric intensive care unit (PICU) screening for abusive head trauma (AHT) vs AHT screening guided by a previously validated 4-variable clinical prediction rule (CPR) in datasets used by the Pediatric Brain Injury Research Network to derive and validate the CPR. STUDY DESIGN: We calculated CPR-based estimates of abuse probability for all 500 patients in the datasets. Next, we demonstrated a positive and very strong correlation between these estimates of abuse probability and the overall diagnostic yields of our patients' completed skeletal surveys and retinal examinations. Having demonstrated this correlation, we applied mean estimates of abuse probability to predict additional, positive abuse evaluations among patients lacking skeletal survey and/or retinal examination. Finally, we used these predictions of additional, positive abuse evaluations to extrapolate and compare AHT detection (and 2 other measures of AHT screening accuracy) in actual PICU screening for AHT vs AHT screening guided by the CPR. RESULTS: Our results suggest that AHT screening guided by the CPR could theoretically increase AHT detection in PICU settings from 87%-96% (P < .001), and increase the overall diagnostic yield of completed abuse evaluations from 49%-56% (P = .058), while targeting slightly fewer, though not significantly less, children for abuse evaluation. CONCLUSIONS: Applied accurately and consistently, the recently validated, 4-variable CPR could theoretically improve the accuracy of AHT screening in PICU settings.

Validation of a clinical prediction rule for pediatric abusive head trauma.

BACKGROUND AND OBJECTIVE: To reduce missed cases of pediatric abusive head trauma (AHT), Pediatric Brain Injury Research Network investigators derived a 4-variable AHT clinical prediction rule (CPR) with sensitivity of .96. Our objective was to validate the screening performance of this AHT CPR in a new, equivalent patient population. METHODS: We conducted a prospective, multicenter, observational, cross-sectional study. Applying the same inclusion criteria, definitional criteria for AHT, and methods used in the completed derivation study, Pediatric Brain Injury Research Network investigators captured complete clinical, historical, and radiologic data on 291 acutely head-injured children <3 years of age admitted to PICUs at 14 participating sites, sorted them into comparison groups of abusive and nonabusive head trauma, and measured the screening performance of the AHT CPR. RESULTS: In this new patient population, the 4-variable AHT CPR demonstrated sensitivity of .96, specificity of .46, positive predictive value of .55, negative predictive value of .93, positive likelihood ratio of 1.67, and negative likelihood ratio of 0.09. Secondary analysis revealed that the AHT CPR identified 98% of study patients who were ultimately diagnosed with AHT. CONCLUSIONS: Four readily available variables (acute respiratory compromise before admission; bruising of the torso, ears, or neck; bilateral or interhemispheric subdural hemorrhages or collections; and any skull fractures other than an isolated, unilateral, nondiastatic, linear, parietal fracture) identify AHT with high sensitivity in young, acutely head-injured children admitted to the PICU.

Variability in IRBs regarding parental acceptance of passive consent.

OBJECTIVE: Passive, opt-out recruitment strategies have the potential to improve efficiency and enlarge the participant pool for clinical studies. We report on the feasibility of using a passive consent strategy for a multicenter pediatric study. METHODS: We assessed the response to passive and active control recruitment strategies used in a multicenter pediatric cohort study and describe the variability in acceptance among institutional review boards (IRBs) and parents of pediatric patients. RESULTS: Twenty-six pediatric centers submitted IRB applications; 24 centers participated. Sixteen IRBs approved the proposed passive recruitment strategy, and 6 IRBs required active consent strategies; 2 centers used a modified participation mode using control subjects from neighboring centers. In all, 4529 potential participants were identified across 22 centers. In the pre-enrollment phase, opt-out rates were significantly lower in the passive consent group compared with the active recruitment centers (1.6% vs. 11.8%; P < .001). During the enrollment phase, however, refusal rates in the passive consent group were significantly higher (38.1% vs. 12.2%; P = .004). The overall refusal rate across both groups was 33.3%. CONCLUSIONS: IRB variability in interpretation and application of regulations affects consistency of study procedure across sites and may reduce validity of study findings. Opt-out consent allowed us to create a large representative pool of control subjects. Parents were more likely to refuse to be approached for a study in the pre-enrollment phase when active consent was used, but were more likely to decline actual study enrollment when passive consent was used in the pre-enrollment period.

Ventilator-associated tracheobronchitis in a mixed medical/surgical pediatric ICU.

BACKGROUND: Adult studies have demonstrated that ventilator-associated tracheobronchitis (VAT) may be a precursor to ventilator-associated pneumonia (VAP). No published data on VAT in pediatric ICUs (PICUs) were found. The purposes of this retrospective, descriptive study are to describe the incidence, characteristics, and outcomes of patients at risk for VAT and formalize a process of VAT surveillance in the PICU population. METHODS: All patients meeting criteria for VAT during 2009-2010 were reviewed and data collected on risk of mortality, index of mortality, interventions, demographic data, respiratory cultures, and the organisms identified in culture. RESULTS: Of 645 patients (32.7%) admitted who met mechanical ventilation criteria, 22 (3.4%) met criteria for VAT. Patients with VAT experienced a significantly longer mean length of stay in the PICU (27.6±22.043 days vs 6.61±7.27 days; P=.000) and higher mean total ventilator time (519.31±457.60 h vs 95.60±138.83 h; P=.000). There was a significant association between tracheostomy and VAT (P=.000) and between chronic ventilator dependence and VAT (P=.002). Gram-negative rods accounted for 71% of cultured microorganisms; staphylococcal or streptococcal species were identified as 26% of causative pathogens. Six of 25 (24%) VAT events identified two or more potentially causative pathogens; four of these (67%) were in patients with a tracheostomy. CONCLUSIONS: VAT occurred less frequently in our PICU than reported in adult studies, and no cases of VAT progressed to VAP in our population. Our results suggest that VAT is a clinically significant health-care-associated infection in the PICU population.

Fluid balance in critically ill children with acute lung injury.

OBJECTIVES: In the Fluid and Catheter Treatment Trial (NCT00281268), adults with acute lung injury randomized to a conservative vs. liberal fluid management protocol had increased days alive and free of mechanical ventilator support (ventilator-free days). Recruiting sufficient children with acute lung injury into a pediatric trial is challenging. A Bayesian statistical approach relies on the adult trial for the a priori effect estimate, requiring fewer patients. Preparing for a Bayesian pediatric trial mirroring the Fluid and Catheter Treatment Trial, we aimed to: 1) identify an inverse association between fluid balance and ventilator-free days; and 2) determine if fluid balance over time is more similar to adults in the Fluid and Catheter Treatment Trial liberal or conservative arms. DESIGN: Multicentered retrospective cohort study. SETTING: Five pediatric intensive care units. PATIENTS: Mechanically ventilated children (age≥1 month to <18 yrs) with acute lung injury admitted in 2007-2010. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Fluid intake, output, and net fluid balance were collected on days 1-7 in 168 children with acute lung injury (median age 3 yrs, median PaO2/FIO2 138) and weight-adjusted (mL/kg). Using multivariable linear regression to adjust for age, gender, race, admission day illness severity, PaO2/FIO2, and vasopressor use, increasing cumulative fluid balance (mL/kg) on day 3 was associated with fewer ventilator-free days (p=.02). Adjusted for weight, daily fluid balance on days 1-3 and cumulative fluid balance on days 1-7 were higher in these children compared to adults in the Fluid and Catheter Treatment Trial conservative arm (p<.001, each day) and was similar to adults in the liberal arm. CONCLUSIONS: Increasing fluid balance on day 3 in children with acute lung injury at these centers is independently associated with fewer ventilator-free days. Our findings and the similarity of fluid balance patterns in our cohort to adults in the Fluid and Catheter Treatment Trial liberal arm demonstrate the need to determine whether a conservative fluid management strategy improves clinical outcomes in children with acute lung injury and support a Bayesian trial mirroring the Fluid and Catheter Treatment Trial.

Incidence and risk factors associated with venous thrombotic events in pediatric intensive care unit patients.

OBJECTIVE: To evaluate the incidence and risk factors associated with venous thromboembolism (VTE) in children admitted to pediatric intensive care units (PICUs). DESIGN: Prospective observational study. SETTING: Eleven tertiary care PICUs in the United States. PATIENTS: Children who were admitted to PICUs and had radiographically confirmed VTE over a rolling 6-month period were enrolled in the study. Demographic, patient-related, and outcomes data were collected and compared with all children admitted during the same period. INTERVENTIONS: None. RESULTS: : Sixty-six symptomatic VTE were documented in sixty-two patients among 6653 patients admitted to 11 PICUs. Thirteen (19.7%) of the thrombi were present on admission. The incidence rate was 0.74% (range, 0-2.7% per PICU) with a point prevalence of 0.93%. Doppler ultrasound was most frequently used to diagnose or confirm a suspected VTE. Variables associated with unadjusted risk for VTE include: younger age (3.8 months for patients with VTE vs. 51 months for non-VTE patients, p < .001), cardiac diagnosis (41% in VTE cases vs. 15% in non-VTE, p < .001), pre-/post-operative status (63% in VTE cases vs. 40% in non-VTE, p = .001), presence of central venous catheter (88% in VTE case vs. 17% in non-VTE, p < .001), or mechanical ventilation (85% in VTE cases vs. 30% non-VTE, p < .001). Multivariate analysis showed increased risk of VTE with CVC (odds ratio 6.9; confidence interval 2.7-17.5) and mechanical ventilation (odds ratio 2.8; confidence interval 0.98-7.93). Children with VTE were sicker (Pediatric Index of Mortality 2 score risk of mortality of 3.0% vs. 0.9%; p<0.0001), stayed longer in the ICU (21.2 days vs. 1.6 days; p < .0001) and had increased mortality (10.2% vs. 2.6; p < .0001). CONCLUSIONS: Children admitted to the PICU have an increased risk of VTE. The presence of a CVC is the strongest risk factor for VTE in this PICU population. Children with VTE were younger, sicker, stayed longer in PICU, and had a higher mortality rate.

Current treatment practices of venous thromboembolism in children admitted to pediatric intensive care units.

OBJECTIVE: To describe current treatment practices of VTE in patients admitted to a pediatric intensive care unit (PICU) and compare these practices to published guidelines. BACKGROUND: While the incidence of VTE is increasing, current treatment practices of VTE in patients admitted to PICUs are not known. METHODS: This multicenter, prospective, observational study enrolled patients with confirmed VTE admitted to 11 PICUs over a rolling 6-month study period. Treatment data were collected and analyzed. RESULTS: Sixty-six VTEs occurred in 6653 patients. Empiric treatment for VTE was initiated in 30% prior to VTE confirmation, and children with cyanotic heart disease were 15.7 times more like to receive empiric therapy. Overall, 78% received systemic anticoagulation, 8% treated with only catheter-based interventions, and 13% of VTE were not treated. Seven patients (11%) underwent systemic fibrinolysis; more commonly in neonates (23%) vs children (5%). Surgical and interventional procedures were performed on 4 patients. The American College of Chest Physicians recommendations were incompletely followed. Only 28% of the 32 cases treated with low molecular weight heparin titrated dosing to a goal anti-FXa level 0.5-1. Five of the 15 cases treated with unfractionated heparin titrated dosing to aPTT 60-90, and one case did not use goal-directed therapy. CONCLUSIONS: Confirmed VTEs in patients admitted to PICUs are most frequently treated with systemic anticoagulation; however, more intensive treatments such as systemic thrombolysis and surgical or interventional procedures are not uncommon in this critically ill population. Current practices deviate from the published antithrombotic guidelines developed for the general pediatric population.
