Post-Intensive Care Sequelae in Pediatrics-Results of an Early Rehabilitation Implementation Study

OBJECTIVES

To compare post-PICU discharge functioning, health-related quality of life (HRQL), and parental stress before and after the implementation of an early rehabilitation bundle.

DESIGN AND SETTING

Prospective cohort substudy within an early rehabilitation implementation program, conducted at the PICUs at McMaster Children's Hospital and London Health Sciences, London, Ontario, Canada.

INTERVENTIONS

A bundle consisting of: 1) analgesia-first sedation; 2) delirium monitoring and prevention; and 3) early mobilization. Patients with an anticipated 48-hour PICU length of stay were approached for consent to participate.

PATIENTS

Critically ill children with an anticipated 48-hour PICU length of stay were approached for consent to participate.

MEASUREMENTS AND MAIN RESULTS

Patient-/proxy-reported outcome measures were assessed at baseline, PICU discharge, and 1 and 3 months post-PICU discharge using: 1) Pediatric Evaluation of Disability Inventory Computer Adaptive Test to assess physical, social, cognitive, and responsibility/caregiver domains of functioning; 2) KIDSCREEN to assess HRQL; and 3) the Pediatric Inventory for Parents to assess caregiver stress. A total of 117 participants were enrolled. Patient demographic characteristics were similar in the pre- and post-intervention groups. Following bundle implementation, 30 of 47 respondents (63.8%) experienced functional decline and 18 of 45 (40%) experienced low HRQL at PICU discharge. Eighteen of 36 (50%) at 1 month and 14 of 38 (36.8%) at 3 months experienced either persistent functional decline and/or low HRQL; 2.8% and 2.6% at 1- and 3-month follow-up, respectively, experienced both persistent functional decline and low HRQL. There were no significant differences in the rates of persistent functional decline, low HRQL, or caregiver stress scores post-bundle compared with pre-rehabilitation bundle implementation.

CONCLUSIONS

We were unable to adequately determine the efficacy of a rehabilitation bundle on patient-centered outcomes as this substudy was not powered for these outcomes. Our results did reveal that persistent low functioning is common in PICU survivors, more common than low HRQL, while experiencing both functional decline and low HRQL was uncommon.

Early Rehabilitation in Critically ill Children: A Two Center Implementation Study

OBJECTIVES

To implement an early rehabilitation bundle in two Canadian PICUs.

DESIGN AND SETTING

Implementation study in the PICUs at McMaster Children's Hospital (site 1) and London Health Sciences (site 2).

PATIENTS

All children under 18 years old admitted to the PICU were eligible for the intervention.

INTERVENTIONS

A bundle consisting of: 1) analgesia-first sedation; 2) delirium monitoring and prevention; and 3) early mobilization.

MEASUREMENTS AND MAIN RESULTS

Primary outcomes were the duration of implementation, bundle compliance, process of care, safety, and the factors influencing implementation. Secondary endpoints were the impact of the bundle on clinical outcomes such as pain, delirium, iatrogenic withdrawal, ventilator-free days, length of stay, and mortality. Implementation occurred over 26 months (August 2018 to October 2020). Data were collected on 1,036 patients representing 4,065 patient days. Bundle compliance was optimized within 6 months of roll-out. Goal setting for mobilization and level of arousal improved significantly (p < 0.01). Benzodiazepine, opioid, and dexmedetomidine use decreased in site 1 by 23.2% (95% CI, 30.8-15.5%), 26.1% (95% CI, 34.8-17.4%), and 9.2% (95% CI, 18.2-0.2%) patient exposure days, respectively, while at site 2, only dexmedetomidine exposure decreased significantly by 10.5% patient days (95% CI, 19.8-1.1%). Patient comfort, safety, and nursing workload were not adversely affected. There was no significant impact of the bundle on the rate of delirium, ventilator-free days, length of PICU stay, or mortality. Key facilitators to implementation included institutional support, unit-wide practice guidelines, dedicated PICU educators, easily accessible resources, and family engagement.

CONCLUSIONS

A rehabilitation bundle can improve processes of care and reduce patient sedative exposure without increasing patient discomfort, nursing workload, or harm. We did not observe an impact on short-term clinical outcomes. The efficacy of a PICU-rehabilitation bundle requires ongoing study. Lessons learned in this study provide evidence to inform rehabilitation implementation in the PICU setting.

"We Aren't Meant to Go Through the Hardest Parts of Our Lives Alone": Family Experience With Restricted PICU Presence During the COVID-19 Pandemic

CONTEXT

PICUs across Canada restricted family presence (RFP) in response to the COVID-19 pandemic from allowing two or more family members to often only one family member at the bedside. The objective of this study was to describe the experiences and impact of RFP on families of critically ill children to inform future policy and practice.

HYPOTHESIS

RFP policies negatively impacted families of PICU patients and caused moral distress.

METHODS AND MODELS

National, cross-sectional, online, self-administered survey. Family members of children admitted to a Canadian PICU between March 2020 and February 2021 were invited to complete the survey. RFP-attributable distress was measured with a modified distress thermometer (0-10). Closed-ended questions were reported with descriptive statistics and multivariable linear regression assessed factors associated with RFP-attributable distress. Open-ended questions were analyzed using inductive content analysis.

RESULTS

Of 250 respondents who experienced RFP, 124 (49.6%) were restricted to one family member at the bedside. The median amount of distress that families attributed to RFP policies was 6 (range: 0-10). Families described isolation, removal of supports, and perception of trauma related to RFP. Most families (183, 73.2%) felt that policies were enforced in a way that made them feel valued by PICU clinicians, which was associated with less RFP-attributable distress. Differential impact was seen where families with lower household income indicated higher RFP-attributable distress score (2.35; 95% CI, 0.53-4.17; p = 0.03). Most respondents suggested that future policies should allow at least two family members at the bedside.

INTERPRETATIONS AND CONCLUSIONS

Families of children admitted to PICUs during the COVID-19 pandemic described increased distress, trauma, and removal of supports due to RFP policies. Vulnerable families showed an increased odds of higher distress. Healthcare professionals played an important role in mitigating distress. Allowance of at least two family members at the bedside should be considered for future policy.

A realist review of the effective implementation of the ICU Liberation Bundle in the paediatric intensive care unit setting

OBJECTIVE

The objective of this study was to produce an evidence base of what works, for whom, and in what context when implementing the ICU Liberation Bundle into the paediatric intensive care unit (PICU).

REVIEW METHOD USED

This is a realist review (a review that considers what works, for whom, and in what context) of contemporary international literature.

DATA SOURCES

Data were collected via electronic searches of CINAHL, PubMed, EMBASE and MEDLINE, Google Scholar, and Web of Science for articles published before October 2020.

REVIEW METHOD

An initial scoping search identified the underpinning theory of the implementation of the ICU Liberation Bundle (a multifactor intervention aimed at improving patient outcomes) which was mapped onto the Consolidated Framework for Implementation Research (CFIR). We identified 547 unique citations; 12 full-text papers were included that reported eight studies. Data were extracted and mapped to the CFIR domains.

RESULTS

Data mapped to all CFIR domains. Characteristics of individuals included involvement of key stakeholders, champions, and parents and understanding of staff attitudes and perceptions of the intervention, and all bedside staff members were involved and given training. Within the inner setting, understanding of unit culture, ensuring effective support systems in place, knowledge of the baseline, and leadership support, and buy-in were important. Culture of family-centred care and alignment of the intervention to national guidelines related to the outer setting. Intervention characteristics included the number and timings of interventions, de-escalation rounding checklists, the use of age-appropriate and validated assessment tools, and local policies for the bundle. The process included set training program, senior unit/hospital team consultation on all processes, continual audit adherence to the bundle and feedback, and celebration of successes.

CONCLUSIONS

This novel realist review of the literature identified that successful implementation of the ICU Liberation Bundle into PICU settings involves the following: (i) a thorough understanding of the PICU context, including baseline metrics, resources, and staff attitudes; (ii) using contextual information to adapt the intervention elements to ensure fit; and (iii) both clinical effectiveness and implementation outcomes must be measured.

Improving Daily Patient Goal-Setting and Team Communication: The Liber8 Glass Door Project

OBJECTIVES

To develop and implement a tool to improve daily patient goal setting, team collaboration and communication.

DESIGN

Quality improvement implementation project.

SETTING

Tertiary-level PICU.

PATIENTS

Inpatient children less than 18 years old requiring ICU level care.

INTERVENTION

A "Glass Door" daily goals communication tool located in the door front of each patient room.

MEASUREMENTS AND MAIN RESULTS

We used Pronovost's 4 E's model to implement the Glass Door. Primary outcomes were uptake of goal setting, healthcare team discussion rate around goals, rounding efficiency, acceptability and sustainability of the Glass Door. The total implementation duration from engagement to evaluation of sustainability was 24 months. Goal setting increased significantly from 22.9% to 90.7% ( p < 0.01) patient-days using the Glass Door compared to a paper-based daily goals checklist (DGC). One-year post implementation, the uptake was sustained at 93.1% ( p = 0.04). Rounding time decreased from a median of 11.7 minutes (95% CI, 10.9-12.4 min) to 7.5 minutes (95% CI, 6.9-7.9 min) per patient post-implementation ( p < 0.01). Goal discussions on ward rounds increased overall from 40.1% to 58.5% ( p < 0.01). Ninety-one percent of team members perceive that the Glass Door improves communication for patient care, and 80% preferred the Glass Door to the DGC for communicating patient goals with other team members. Sixty-six percent of family members found the Glass Door helpful in understanding the daily plan and 83% found it helpful in ensuring thorough discussion among the PICU team.

CONCLUSIONS

The Glass Door is a highly visible tool that can improve patient goal setting and collaborative team discussion with good uptake and acceptability among healthcare team members and patient families.

A multi-centre retrospective study of Nocardia speciation and antimicrobial susceptibility in Queensland, Australia

The study aims to characterise the species identification and antimicrobial susceptibility testing (AST) results of Nocardial isolates from adult patients across major public hospitals in Queensland, Australia, over a 15-year period. A multi-centre retrospective observational study of Nocardia sp. isolates was conducted from 7 major public hospitals in Queensland, Australia, over a 15-year period. Clinical samples from patients aged ≥ 18 years that isolated Nocardia sp. were included. Demographic and clinical data were collected, along with species identification and AST results. Overall, 484 Nocardia sp. were isolated. Most patients were male (297, 61%) with a mean (IQR) age of 60 (51-75) and a median (IQR) Charlson Comorbidity Index of 4 (2-6). Of these, 239 (49%) patients were immunosuppressed. Organisms were most frequently isolated from sputum (174, 36%), and superficial swabs (102, 21%). Patients presented with pulmonary infections (165, 35%) and superficial skin and soft tissue infections (87, 18%) most commonly. One hundred (21%) isolates were deemed pulmonary colonisation and were not treated. Of the speciated organisms, N. nova complex was the most common (93, 19%), followed by N. farcinica complex (79, 16%). Organisms were reliably susceptible to linezolid (240/245, 98%), amikacin (455/470, 97%), and trimethoprim/sulfamethoxazole (459/476, 96%), but less so to imipenem (243/472, 51%) and ceftriaxone (261/448, 58%). This is the largest Australian description of Nocardia sp. to date. Given antimicrobials are often commenced prior to AST results and sometimes even speciation, characterisation of local species and antibiogram data is important to guide empiric choices and local guidelines.

Lived Experiences of Delirium in Critically Ill Children: A Qualitative Study

The aim of this study was to understand the lived experiences of delirium in critically ill children. We conducted phenomenological qualitative interviews with critically ill pediatric survivors aged 0 to 18 years who had experienced delirium, along with their family caregivers and health care providers, from pediatric intensive care units in two tertiary care children's hospitals in Canada. Cases were identified if they had a Cornell Assessment of Pediatric Delirium (CAPD) score of ≥ 9 for at least 48 hours. Thirteen interviews were conducted, representing 10 index patients with delirium (age range: 7 weeks to 17 years). Participants shared experiences that were divided into themes of delirium symptoms, the impact of delirium, and their experience with the care of delirium. Within each theme, subthemes were identified. Symptoms of delirium included hallucinations, fluctuating symptoms, and lack of eye contact. Children were often described as “not himself/herself.” Delirium had long-lasting impact on patients; memories remained prominent even after the hospital stay. Family members and health care providers often felt helpless and ill-prepared to manage delirium. The delirium experience had significant impact on loved ones, causing persistent and vicarious suffering after the critical illness course. Family members and health care providers prioritized nonpharmacological strategies, family presence, and education as key strategies for delirium management. The lived experience of delirium in both infants and older children is physically, psychologically, and emotionally distressing. Given the traumatic long-term consequences, there is an urgent need to target delirium education, management, and prevention to improve long-term outcomes in PICU survivors and their families.

A Core Outcome Measurement Set for Pediatric Critical Care

OBJECTIVES

To identify a PICU Core Outcome Measurement Set (PICU COMS), a set of measures that can be used to evaluate the PICU Core Outcome Set (PICU COS) domains in PICU patients and their families.

DESIGN

A modified Delphi consensus process.

SETTING

Four webinars attended by PICU physicians and nurses, pediatric surgeons, rehabilitation physicians, and scientists with expertise in PICU clinical care or research ( n = 35). Attendees were from eight countries and convened from the Pediatric Acute Lung Injury and Sepsis Investigators Pediatric Outcomes STudies after PICU Investigators and the Eunice Kennedy Shriver National Institute of Child Health and Human Development Collaborative Pediatric Critical Care Research Network PICU COS Investigators.

SUBJECTS

Measures to assess outcome domains of the PICU COS are as follows: cognitive, emotional, overall (including health-related quality of life), physical, and family health. Measures evaluating social health were also considered.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Measures were classified as general or additional based on generalizability across PICU populations, feasibility, and relevance to specific COS domains. Measures with high consensus, defined as 80% agreement for inclusion, were selected for the PICU COMS. Among 140 candidate measures, 24 were delineated as general (broadly applicable) and, of these, 10 achieved consensus for inclusion in the COMS (7 patient-oriented and 3 family-oriented). Six of the seven patient measures were applicable to the broadest range of patients, diagnoses, and developmental abilities. All were validated in pediatric populations and have normative pediatric data. Twenty additional measures focusing on specific populations or in-depth evaluation of a COS subdomain also met consensus for inclusion as COMS additional measures.

CONCLUSIONS

The PICU COMS delineates measures to evaluate domains in the PICU COS and facilitates comparability across future research studies to characterize PICU survivorship and enable interventional studies to target long-term outcomes after critical illness.

Guidance for Structuring a Pediatric Intermediate Care Unit

The purpose of this policy statement is to update the 2004 American Academy of Pediatrics clinical report and provide enhanced guidance for institutions, administrators, and providers in the development and operation of a pediatric intermediate care unit (IMCU). Since 2004, there have been significant advances in pediatric medical, surgical, and critical care that have resulted in an evolution in the acuity and complexity of children potentially requiring IMCU admission. A group of 9 clinical experts in pediatric critical care, hospital medicine, intermediate care, and surgery developed a consensus on priority topics requiring updates, reviewed the relevant evidence, and, through a series of virtual meetings, developed the document. The intended audience of this policy statement is broad and includes pediatric critical care professionals, pediatric hospitalists, pediatric surgeons, other pediatric medical and surgical subspecialists, general pediatricians, nurses, social workers, care coordinators, hospital administrators, health care funders, and policymakers, primarily in resource-rich settings. Key priority topics were delineation of core principles for an IMCU, clarification of target populations, staffing recommendations, and payment.

Outcomes of critically ill COVID-19 survivors and caregivers: a case study-centred narrative review

PURPOSE

Critical illness is a transformative experience for both patients and their family members. For COVID-19 patients admitted to the intensive care unit (ICU), survival may be the start of a long road to recovery. Our knowledge of the post-ICU long-term sequelae of acute respiratory distress syndrome (ARDS) and severe acute respiratory syndrome (SARS) may inform our understanding and management of the long-term effects of COVID-19.

SOURCE

We identified international and Canadian epidemiologic data on ICU admissions for COVID-19, COVID-19 pathophysiology, emerging ICU practice patterns, early reports of long-term outcomes, and federal support programs for survivors and their families. Centred around an illustrating case study, we applied relevant literature from ARDS and SARS to contextualize knowledge within emerging COVID-19 research and extrapolate findings to future long-term outcomes.

PRINCIPAL FINDINGS

COVID-19 is a multisystem disease with unknown long-term morbidity and mortality. Its pathophysiology is distinct and unique from ARDS, SARS, and critical illness. Nevertheless, based on initial reports of critical care management for COVID-19 and the varied injurious supportive practices employed in the ICU, patients and families are at risk for post-intensive care syndrome. The distinct incremental risk of COVID-19 multiple organ dysfunction is unknown. The risk of mood disorders in family members may be further exacerbated by imposed isolation and stigma.

CONCLUSION

Emerging literature on COVID-19 outcomes suggests some similarities with those of ARDS/SARS and prolonged mechanical ventilation. The pathophysiology of COVID-19 is presented here in the context of early outcome data and to inform an agenda for longitudinal research for patients and families.

A High-Throughput Platform for the Rapid Screening of Vitamin D Status by Direct Infusion-Tandem Mass Spectrometry

Vitamin D is an important fat-soluble prohormone with pleiotropic effects on human health, such as immunomodulation of the innate and adaptive immune system. There is an unmet clinical need for a rapid screening platform for 25-hydroxyvitamin D (25OH-D) determination without chromatographic separation that offers better precision and accuracy than immunoassays. Here, we introduce a high-throughput method for assessing vitamin D status from blood specimens based on direct infusion-MS/MS (DI-MS/MS) following click derivatization using 2-nitrosopyridine. We developed an optimized liquid-phase extraction protocol to minimize ion suppression when directly infusing serum or plasma extracts via a capillary electrophoresis system for quantitative determination of 25OH-D. Acceptable reproducibility (mean coefficient of variation = 10.9%, n = 412), recovery (mean = 102% at 15, 30, and 45 nmol/l), and linearity (R² > 0.998) were achieved for 25OH-D with lower detection limits (limit of detection ∼1.2 nmol/l, S/N ∼ 3), greater throughput (∼3 min/sample), and less bias than a commercial chemiluminescence immunoassay prone to batch effects. There was mutual agreement in 25OH-D concentrations from reference blood samples measured by DI-MS/MS as compared with LC-MS/MS (mean bias = 7.8%, n = 18). We also demonstrate that this method could reduce immunoassay misclassification of vitamin D deficiency in a cohort of critically ill children (n = 30). In conclusion, DI-MS/MS offers a viable alternative to LC-MS/MS for assessment of vitamin D status in support of large-scale studies in nutritional epidemiology as well as clinical trials to rapidly screen individual patients who may benefit from vitamin D supplementation.

Pediatric Chronic Critical Illness: Protocol for a Scoping Review

BACKGROUND

Improvements in the delivery of intensive care have increased survival among even the most critically ill children, thereby leading to a growing number of children with chronic complex medical conditions in the pediatric intensive care unit (PICU). Some of these children are at a significant risk of recurrent and prolonged critical illness, with higher morbidity and mortality, making them a unique population described as having chronic critical illness (CCI). To date, pediatric CCI has been understudied and lacks an accepted consensus case definition.

OBJECTIVE

This study aims to describe the protocol and methodology used to perform a scoping review that will describe how pediatric CCI has been defined in the literature, including the concept of prolonged PICU admission and the methodologies used to develop any existing definitions. It also aims to describe patient characteristics and outcomes evaluated in the included studies.

METHODS

We will search four electronic databases for studies that evaluated children admitted to any PICU identified with CCI. We will also search for studies describing prolonged PICU admission, as this concept is related to pediatric CCI. Furthermore, we will develop a hybrid crowdsourcing and machine learning (ML) methodology to complete citation screening. Screening and data abstraction will be performed by 2 reviewers independently and in duplicate. Data abstraction will include the details of population definitions, demographic and clinical characteristics of children with CCI, and evaluated outcomes.

RESULTS

The database search, crowd reviewer recruitment, and ML algorithm development began in March 2021. Citation screening and data abstraction were completed in April 2021. Final data verification is ongoing, with analysis and results anticipated to be completed by fall 2021.

CONCLUSIONS

This scoping review will describe the existing or suggested definitions of pediatric CCI and important demographic and clinical characteristics of patients to whom these definitions have been applied. This review's results will help inform the development of a consensus case definition for pediatric CCI and set a priority agenda for future research. We will use and demonstrate the validity of crowdsourcing and ML methodologies for improving the efficiency of large scoping reviews.

Levetiracetam Versus Phenytoin or Fosphenytoin for Second-Line Treatment of Pediatric Status Epilepticus: A Meta-Analysis

OBJECTIVE

To synthesize the available evidence examining the efficacy and safety of levetiracetam compared with phenytoin or fosphenytoin in benzodiazepine-refractory pediatric status epilepticus.

DATA SOURCES

We searched (from inception until April 27, 2020) Ovid MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials.

STUDY SELECTION

Two reviewers, independently and in duplicate, screened citations and manuscripts for eligible randomized controlled trials.

DATA EXTRACTION AND SYNTHESIS

Independently and in duplicate, we performed data abstraction, risk of bias assessment, and certainty assessment using Grading of Recommendations, Assessment, Development, and Evaluation. We performed meta-analyses using random-effect models or, if insufficient data, presented findings narratively.

RESULTS

We identified seven randomized controlled trials (n = 1,575). Pooled analysis demonstrated low certainty evidence for no difference of levetiracetam on time to seizure cessation (mean difference, -3.11 min; 95% CI, -6.67 to 0.45), early seizure cessation (relative risk, 1.09, 95% CI, 0.95-1.26), or late seizure cessation (relative risk, 1.05; 95% CI, 0.93-1.18). Adverse event outcomes were limited by low event numbers. We found low certainty evidence for less respiratory depression with levetiracetam (relative risk, 0.28; 95% CI, 0.12-0.69).

CONCLUSIONS

The efficacy of levetiracetam is comparable with phenytoin or fosphenytoin in children with benzodiazepine-refractory status epilepticus (low certainty evidence). Levetiracetam may cause less respiratory depression. Clinicians and guideline developers should weigh safety profiles when choosing between these agents.

Magnetic Resonance Imaging Findings Are Associated with Long-Term Global Neurological Function or Death after Traumatic Brain Injury in Critically Ill Children

The identification of children with traumatic brain injury (TBI) who are at risk of death or poor global neurological functional outcome remains a challenge. Magnetic resonance imaging (MRI) can detect several brain pathologies that are a result of TBI; however, the types and locations of pathology that are the most predictive remain to be determined. Forty-two critically ill children with TBI were recruited prospectively from pediatric intensive care units at five Canadian children's hospitals. Pathologies detected on subacute phase MRIs included cerebral hematoma, herniation, cerebral laceration, cerebral edema, midline shift, and the presence and location of cerebral contusion or diffuse axonal injury (DAI) in 28 regions of interest were assessed. Global functional outcome or death more than 12 months post-injury was assessed using the Pediatric Cerebral Performance Category score. Linear modeling was employed to evaluate the utility of an MRI composite score for predicting long-term global neurological function or death after injury, and nonlinear Random Forest modeling was used to identify which MRI features have the most predictive utility. A linear predictive model of favorable versus unfavorable long-term outcomes was significantly improved when an MRI composite score was added to clinical variables. Nonlinear Random Forest modeling identified five MRI variables as stable predictors of poor outcomes: presence of herniation, DAI in the parietal lobe, DAI in the subcortical white matter, DAI in the posterior corpus callosum, and cerebral contusion in the anterior temporal lobe. Clinical MRI has prognostic value to identify children with TBI at risk of long-term unfavorable outcomes.

Prevalence of Acute Rehabilitation for Kids in the PICU: A Canadian Multicenter Point Prevalence Study

OBJECTIVES

To evaluate mobilization practices, barriers, and mobility-related adverse events in Canadian PICUs.

DESIGN

National 2-day point prevalence study.

SETTING

Thirteen PICUs across Canada.

PATIENTS

Children with a minimum 72-hour PICU length of stay on the allocated study day.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Outcomes of interest were the prevalence and nature of mobilization activities, rehabilitation resources, adverse events, and factors associated with out-of-bed mobility and therapist-provided mobility. Two PICUs (15%) had early mobilization practice guidelines, and one PICU (8%) reported a formal process for engaging families in the mobilization of patients. The prevalence of mobilization was 110 of 137 patient-days (80%). The commonest activity was out-of-bed mobility (87/137; 64% patient-days); there was no active mobilization on 46 patient-days (34%). Therapists provided mobility on 33% of patient-days. Mobility was most commonly facilitated by nurses (74% events) and family (49% events). Family participation was strongly associated with out-of-bed mobility (odds ratio 6.4; p = 0.001). Intubated, mechanically ventilated patients were mobilized out-of-bed on 18 of 50 patient-days (36%). However, the presence of an endotracheal tube, vasoactive infusions, and age greater than or equal to 3 years were independently associated with not being mobilized out-of-bed. Barriers were reported on 58 of 137 patient-days (42%), and adverse events occurred in 22 of 387 mobility events (6%).

CONCLUSIONS

Mobilization is common and safe, and the majority of children in Canadian PICUs are being mobilized out-of-bed, even when mechanically ventilated. Family engagement in PICU-based rehabilitation is increasing. This study provides encouraging evidence that common barriers can be overcome in order to safely mobilize children in PICUs.

The LiberAction Project: Implementation of a Pediatric Liberation Bundle to Screen Delirium, Reduce Benzodiazepine Sedation, and Provide Early Mobilization in a Human Resource-Limited Pediatric Intensive Care Unit

Background: Delirium, bed immobilization, and heavy sedation are among the major contributors of pediatric post-intensive care syndrome. Recently, the Society of Critical Care Medicine has proposed the implementation of daily interventions to minimize the incidence of these morbidities and optimize children functional outcomes and quality of life. Unfortunately, these interventions require important clinical and economical efforts which prevent their use in many pediatric intensive care units (PICU). Aim: First, to evaluate the feasibility and safety of a PICU bundle implementation prioritizing delirium screening and treatment, early mobilization (<72 h from PICU admission) and benzodiazepine-limited sedation in a human resource-limited PICU. Second, to evaluate the incidence of delirium and describe the early mobilization practices and sedative drugs used during the pre- and post-implementation periods. Third, to describe the barriers and adverse events encountered during early mobilization. Methods: This observational study was structured in a pre- (15th November 2019-30th June 2020) and post-implementation period (1st July 2020-31st December 2020). All patients admitted in PICU for more than 72 h during the pre and post-implementation period were included in the study. Patients were excluded if early mobilization was contraindicated. During the pre-implementation period, a rehabilitation program including delirium screening and treatment, early mobilization and benzodiazepine-sparing sedation guidelines was developed and all PICU staff trained. During the post-implementation period, delirium screening with the Connell Assessment of Pediatric Delirium scale was implemented at bedside. Early mobilization was performed using a structured tiered protocol and a new sedation protocol, limiting the use of benzodiazepine, was adopted. Results: Two hundred and twenty-five children were enrolled in the study, 137 in the pre-implementation period and 88 in the post-implementation period. Adherence to delirium screening, benzodiazepine-limited sedation and early mobilization was 90.9, 81.1, and 70.4%, respectively. Incidence of delirium was 23% in the post-implementation period. The median cumulative dose of benzodiazepines corrected for the total number of sedation days (mg/kg/sedation days) was significantly lower in the post-implementation period compared with the pre-implementation period: [0.83 (IQR: 0.53-1.31) vs. 0.74 (IQR: 0.55-1.16), p = 0.0001]. The median cumulative doses of fentanyl, remifentanil, and morphine corrected for the total number of sedation days were lower in the post-implementation period, but these differences were not significant. The median number of mobilizations per patient and the duration of each mobilization significantly increased in the post-implementation period [3.00 (IQR: 2.0-4.0) vs. 7.00 (IQR: 3.0-12.0); p = 0.004 and 4 min (IQR: 3.50-4.50) vs. 5.50 min (IQR: 5.25-6.5); p < 0.0001, respectively]. Barriers to early mobilization were: disease severity and bed rest orders (55%), lack of physicians' order (20%), lack of human resources (20%), and lack of adequate devices for patient mobilization (5%). No adverse events related to early mobilization were reported in both periods. Duration of mechanical ventilation and PICU length of stay was significantly lower in the post-implementation period as well as the occurrence of iatrogenic withdrawal syndrome. Conclusion: This study showed that the implementation of a PICU liberation bundle prioritizing delirium screening and treatment, benzodiazepine-limited sedation and early mobilization was feasible and safe even in a human resource-limited PICU. Further pediatric studies are needed to evaluate the clinical impact of delirium, benzodiazepine-limited sedation and early mobilization protocols on patients' long-term functional outcomes and on hospital finances.

Surviving sepsis campaign international guidelines for the management of septic shock and sepsis-associated organ dysfunction in children

Objectives

To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction.

Design

A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process.

Methods

The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, “in our practice” statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate.

Results

The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 49 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, “in our practice” statements were provided. In addition, 52 research priorities were identified.

Conclusions

A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

A Core Outcome Set for Pediatric Critical Care

OBJECTIVES

More children are surviving critical illness but are at risk of residual or new health conditions. An evidence-informed and stakeholder-recommended core outcome set is lacking for pediatric critical care outcomes. Our objective was to create a multinational, multistakeholder-recommended pediatric critical care core outcome set for inclusion in clinical and research programs.

DESIGN

A two-round modified Delphi electronic survey was conducted with 333 invited research, clinical, and family/advocate stakeholders. Stakeholders completing the first round were invited to participate in the second. Outcomes scoring greater than 69% "critical" and less than 15% "not important" advanced to round 2 with write-in outcomes considered. The Steering Committee held a virtual consensus conference to determine the final components.

SETTING

Multinational survey.

PATIENTS

Stakeholder participants from six continents representing clinicians, researchers, and family/advocates.

MEASUREMENTS AND MAIN RESULTS

Overall response rates were 75% and 82% for each round. Participants voted on seven Global Domains and 45 Specific Outcomes in round 1, and six Global Domains and 30 Specific Outcomes in round 2. Using overall (three stakeholder groups combined) results, consensus was defined as outcomes scoring greater than 90% "critical" and less than 15% "not important" and were included in the final PICU core outcome set: four Global Domains (Cognitive, Emotional, Physical, and Overall Health) and four Specific Outcomes (Child Health-Related Quality of Life, Pain, Survival, and Communication). Families (n = 21) suggested additional critically important outcomes that did not meet consensus, which were included in the PICU core outcome set-extended.

CONCLUSIONS

The PICU core outcome set and PICU core outcome set-extended are multistakeholder-recommended resources for clinical and research programs that seek to improve outcomes for children with critical illness and their families.

Ventilatory management in extremely low birth weight infants

The improvement in survival in premature infants associated with the evolution of mechanical ventilation has been accompanied by an increase in ventilator induced lung injury. High frequency ventilation has been shown to reduce the incidence of ventilator induced lung injury and hence chronic lung disease in the very low birth weight infant. The evolution in understanding how to best use high frequency ventilation in this population has prompted us to ask whether similar strategies to optimize lung volumes on conventional mechanical ventilation can minimize chronic lung disease in the neonate. We retrospectively reviewed the medical charts of 51 extremely low birth weight infants born in Kingston, Ontario in two epochs, 1990 to 1991 and 1999 to 2000, for ventilatory strategy and outcome. From our review, it is clear that surfactant therapy rapidly changes lung mechanics by improving pulmonary compliance and that lung damage may result if there are not changes in the ventilatory management to reflect the altered compliance. Early ventilation strategies during the apparently stable "honeymoon period" in a patient with respiratory distress syndrome (RDS) has significant implications on long term morbidity. In the era prior to the use of surfactant, 30% of infants died and 40% developed chronic lung disease (CLD). Immediately following the use of surfactant, mortality was reduced to 18%, however, the incidence of CLD increased to 78%. In the most recent era, following 10 years of experience with surfactant and mechanical ventilation, morbidity was 17% and CLD 21%. This study demonstrates that a particularly crucial time is in the immediate period following surfactant administration. The use of lower peak inspiratory pressure (PIP) and mean airway pressure (MAP) over the first 24 hours and an increase in the use of synchronous intermittent mandatory ventilation (SIMV) was associated with an improved outcome. The challenge remaining is to determine how to best utilize a conventional mode of ventilation to best optimize lung volume and protect the immature lung.

Decontamination interventions for the reuse of surgical mask personal protective equipment: a systematic review

BACKGROUND

The high demand for personal protective equipment during the novel coronavirus outbreak has prompted the need to develop strategies to conserve supply. Little is known regarding decontamination interventions to allow for surgical mask reuse.

AIM

To identify and synthesize data from original research evaluating interventions to decontaminate surgical masks for the purpose of reuse.

METHODS

MEDLINE, Embase, CENTRAL, Global Health, the WHO COVID-19 database, Google Scholar, DisasterLit, preprint servers, and prominent journals from inception to April 8^th, 2020, were searched for prospective original research on decontamination interventions for surgical masks. Citation screening was conducted independently in duplicate. Study characteristics, interventions, and outcomes were extracted from included studies by two independent reviewers. Outcomes of interest included impact of decontamination interventions on surgical mask performance and germicidal effects.

FINDINGS

Seven studies met eligibility criteria: one evaluated the effects of heat and chemical interventions applied after mask use on mask performance, and six evaluated interventions applied prior to mask use to enhance antimicrobial properties and/or mask performance. Mask performance and germicidal effects were evaluated with heterogeneous test conditions. Safety outcomes were infrequently evaluated. Mask performance was best preserved with dry heat decontamination. Good germicidal effects were observed in salt-, N-halamine-, and nanoparticle-coated masks.

CONCLUSION

There is limited evidence on the safety or efficacy of surgical mask decontamination. Given the heterogeneous methods used in studies to date, we are unable to draw conclusions on the most efficacious and safe intervention for decontaminating surgical masks.

Caregiver dissatisfaction with their child's participation in home activities after pediatric critical illness

BACKGROUND

Pediatric critical care is often accompanied by a variety of functional impairments. Preliminary evidence suggests children's participation in home activities has a slow trajectory post-pediatric intensive care unit (PICU) discharge, however, additional and more granular knowledge on specific problematic activities is needed to inform patient-centric rehabilitative care. The objectives of this study are to identify common home activities in which caregivers' report dissatisfaction and to determine predictors of caregivers' dissatisfaction with their child's participation in home activities post-PICU discharge.

METHODS

Secondary analyses of data from a prospective cohort study, the Wee-Cover study, using a subsample of caregivers (N = 170) of children 1-17 years, admitted to a PICU ≥48 h with data on our primary outcome measure from at least one time point. Data were gathered at enrollment and at 3 and 6 months post-PICU discharge. Caregivers reported on their dissatisfaction with their child's participation in home activities via the Participation and Environment Measure. Common activities were identified by plotting caregiver dissatisfaction for each activity pre-and post-PICU, reporting activities in which ≥50% of caregivers reported dissatisfaction with post-PICU, and assessing for significantly different dissatisfaction levels between time-points for each activity. Predictors of caregiver dissatisfaction were assessed using Poisson generalized estimated equation models.

RESULTS

There was variability in reported dissatisfaction across all activities; ≥50% of caregivers reported dissatisfaction with five activities, including getting clean, personal care management, and mealtime for younger children and household chores and homework for school-aged children and youth. Four activities had significantly higher caregiver dissatisfaction post-PICU: sleep (children < 5 years), homework, indoor play and games, and computer/video games (children ≥5 years). Home environmental support and the interaction of having participation-focused strategies with receiving PICU-based rehabilitation services were negatively associated with caregiver dissatisfaction. Increased caregiver stress and functional performance were associated with increased dissatisfaction.

CONCLUSIONS

Individualized PICU-based rehabilitation services to determine family priorities and develop participation-focused strategies, specifically those increasing environmental supports within the home, may ease the family's transition home post-PICU.

Priority Outcomes in Critically Ill Children: A Patient and Parent Perspective

BACKGROUND

Outcomes in pediatric critical care research are typically selected by the researcher.

OBJECTIVES

(1) To identify outcomes prioritized by patients and their families following a critical illness and (2) to determine the overlap between patient-centered and researcher-selected study outcomes.

METHODS

An exploratory descriptive qualitative study nested within a longitudinal cohort study conducted in 2 pediatric intensive care units (PICUs). Participants were purposively sampled from the primary cohort to ensure adequate demographic representation. Qualitative descriptive approaches based on naturalistic observation were used to collect data and analyze results. Data were coded by using the International Classification of Functioning, Disability, and Health Children and Youth (ICF-CY) framework.

RESULTS

Twenty-one participants were interviewed a mean of 5.1 months after PICU discharge. Outcomes fell into 2 categories: patient-centered and family-centered. In the former, diagnosis, survival, and prognosis were key priorities during the acute critical illness. Once survival appears possible, functioning (physical, cognitive, and emotional), and factors that influence recovery (ie, rehabilitation, environment, and quality of life) are prioritized. Family-centered outcomes consisted of parents' psychosocial functioning and experience of care. Patient-centered outcomes were covered well by the selected study measures of functioning, but not by the clinical outcome measures.

CONCLUSION

Functioning and quality of life are key patient-centered outcomes during recovery from critical illness. These are not well captured by end points typically used in PICU studies. These results justify the importance of patient- and family-centered outcomes in PICU research and a need to determine how these outcomes can be comprehensively measured.

Measurement and reporting of physical rehabilitation interventions in pediatric critical care: a scoping review

Purpose: To describe and evaluate physical rehabilitation research in critically ill children, including physical rehabilitation intervention reporting.Methods: We searched five electronic databases to 31 December 2018 for prospective physical rehabilitation studies conducted in pediatric intensive care units (PICU). Screening was conducted independently in duplicate. Study characteristics, outcomes, and interventions were extracted from included studies. Quality of study reporting was assessed using standardized tools. Completeness of physical rehabilitation intervention reporting was assessed using the Consensus on Exercise Reporting Template (CERT).Results: We included 20 studies enrolling a total of 2644 patients. Median (Q1,Q3) sample size was 57 (44,104). Seven studies (35%) were randomized controlled trials. Eleven studies (55%) evaluated respiratory interventions, most commonly multicomponent chest physiotherapy (73%). Nine studies (45%) evaluated physical activity interventions, most commonly progressive mobility (56%). The majority of stated outcomes (92.5%) were limited to the PICU setting. Median [Q1,Q3] quality of study reporting was good (77.2% [66.7%,87.4%]), and completeness of physical rehabilitation intervention reporting was moderate (61.9% [45.9%,71.5%]).Conclusion: Physical rehabilitation studies in critically ill children were small, and focused on evaluating respiratory-based interventions and short-term PICU-based outcomes. Reporting of physical rehabilitation interventions was suboptimal. Use of CERT may improve design and reporting in future studies.Implications for rehabilitationWhile physical rehabilitation research in critically ill children is a growing field, there are currently few studies evaluating physical rehabilitation interventions in this population.Physical rehabilitation studies to date have been small, focused on evaluating respiratory-based interventions and short-term outcomes limited to the PICU setting.The reporting of physical rehabilitation interventions in this population is suboptimal, making it challenging for clinicians to reproduce interventions and appraise their efficacy or safety.

Surviving Sepsis Campaign International Guidelines for the Management of Septic Shock and Sepsis-Associated Organ Dysfunction in Children

OBJECTIVES

To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction.

DESIGN

A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process.

METHODS

The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, "in our practice" statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate.

RESULTS

The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 52 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, "in our practice" statements were provided. In addition, 49 research priorities were identified.

CONCLUSIONS

A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

Understanding and Enhancing Sepsis Survivorship. Priorities for Research and Practice

An estimated 14.1 million patients survive sepsis each year. Many survivors experience poor long-term outcomes, including new or worsened neuropsychological impairment; physical disability; and vulnerability to further health deterioration, including recurrent infection, cardiovascular events, and acute renal failure. However, clinical trials and guidelines have focused on shorter-term survival, so there are few data on promoting longer-term recovery. To address this unmet need, the International Sepsis Forum convened a colloquium in February 2018 titled "Understanding and Enhancing Sepsis Survivorship." The goals were to identify gaps and limitations of current research and shorter- and longer-term priorities for understanding and enhancing sepsis survivorship. Twenty-six experts from eight countries participated. The top short-term priorities identified by nominal group technique culminating in formal voting were to better leverage existing databases for research, develop and disseminate educational resources on postsepsis morbidity, and partner with sepsis survivors to define and achieve research priorities. The top longer-term priorities were to study mechanisms of long-term morbidity through large cohort studies with deep phenotyping, build a harmonized global sepsis registry to facilitate enrollment in cohorts and trials, and complete detailed longitudinal follow-up to characterize the diversity of recovery experiences. This perspective reviews colloquium discussions, the identified priorities, and current initiatives to address them.

Collection and Analyses of Cerebrospinal Fluid for Pediatric Translational Research

Cerebrospinal fluid sample collection and analysis is imperative to better elucidate central nervous system injury and disease in children. Sample collection methods are varied and carry with them certain ethical and biologic considerations, complications, and contraindications. Establishing best practices for sample collection, processing, storage, and transport will ensure optimal sample quality. Cerebrospinal fluid samples can be affected by a number of factors including subject age, sampling method, sampling location, volume extracted, fraction, blood contamination, storage methods, and freeze-thaw cycles. Indicators of sample quality can be assessed by matrix-associated laser desorption/ionization time-of-flight mass spectrometry and include cystatin C fragments, oxidized proteins, prostaglandin D synthase, and evidence of blood contamination. Precise documentation of sample collection processes and the establishment of meticulous handling procedures are essential for the creation of clinically relevant biospecimen repositories. In this review we discuss the ethical considerations and best practices for cerebrospinal fluid collection, as well as the influence of preanalytical factors on cerebrospinal fluid analyses. Cerebrospinal fluid biomarkers in highly researched pediatric diseases or disorders are discussed.

Caregiver Strategy Use To Promote Their Child’s Participation in Home-Based Occupations Following Pediatric Critical Illness

Date Presented 04/06/19

Trends in participation-focused strategies used by caregivers of critically ill children who did and did not receive PICU rehabilitation services were identified. Strategies were coded as child focused or to an environmental chapter of the ICF-CY. Caregivers can identify participation-focused strategies, but may benefit from education by their rehabilitation team to develop a broader range of strategies to promote their child’s home participation.

Intravenous Fluid Prescription Practices in Critically Ill Children: A Shift in Focus from Natremia to Chloremia?

Our objective is to evaluate intravenous (IV) fluid prescription practice patterns in critically ill children in the first 72 hours of pediatric intensive care unit (PICU) admission and to evaluate the incidence and predictors of hyperchloremic metabolic acidemia (HCMA) and the association between HCMA and adverse outcomes. This retrospective cohort study was conducted in two tertiary-care Canadian PICUs. Children aged 0 to 18 years admitted to the PICU between January 2015 and January 2016 who received at least 50% of their calculated maintenance fluid requirements parenterally during the first 24 hours of admission were included. Children with known preexisting conditions associated with HCMA, such as renal tubular acidosis and gastrointestinal bicarbonate losses, were excluded. Of the 771 children screened, 543 met eligibility criteria and were included. The commonest prescribed maintenance fluid was 0.9% NaCl (72.9%) followed by lactated Ringer's solution (19.6%) and hypotonic solutions (4.6%). Balanced salt solutions (i.e., lactated Ringer's and Plasma-Lyte) were as commonly administered as unbalanced solutions (0.9% NaCl) for volume expansion (49.6 vs. 48.5%, respectively). Medications contributed to a significant proportion of total daily intake, in excess of bolus fluids. The incidence of hyperchloremia and HCMA was 94.9% (95% confidence interval [CI]: 93.2-96.9; 470/495) and 38.9% (95% CI: 34.6-43.2; 196/504), respectively. Predictors of HCMA were increasing combined bolus and maintenance 0.9% NaCl intake (odds ratio: 1.13; 95% CI: 1.04-1.23) and increasing severity of illness. HCMA was not associated with an increased risk of acute kidney injury, feeding intolerance, or PICU-acquired weakness. Isotonic fluids, specifically 0.9% NaCl, were the most commonly administered maintenance IV fluid in critically ill children. Sources of chloride load are not isolated to resuscitation fluids as previously suggested. Maintenance fluids and fluids administered with medications and IV flushes (fluid creep) are under-recognized significant sources of fluid and electrolyte intake in critically ill children. HCMA is common, and further prospective research is required to determine whether HCMA is indeed harmful in children. However, all significant sources of fluid should be accounted for in the design of future trials comparing balanced and unbalanced salt solutions.

PICU-Based Rehabilitation and Outcomes Assessment: A Survey of Pediatric Critical Care Physicians

OBJECTIVES

Characterize current practices for PICU-based rehabilitation, and physician perceptions and attitudes, barriers, resources, and outcome assessment in contemporary PICU settings.

DESIGN

International, self-administered, quantitative, cross-sectional survey.

SETTING

Online survey distributed from March 2017 to April 2017.

PATIENTS OR SUBJECTS

Pediatric critical care physicians who subscribed to email distribution lists of the Pediatric Acute Lung Injury and Sepsis Investigators, the Pediatric Neurocritical Care Research Group, or the Prevalence of Acute Critical Neurological Disease in Children: A Global Epidemiological Assessment study group, and visitors to the World Federation of Pediatric Intensive and Critical Care Societies website.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of the 170 subjects who began the survey, 148 completed it. Of those who completed the optional respondent information, most reported working in an academic medical setting and were located in the United States. The main findings were 1) a large majority of PICU physicians reported working in institutions with no guidelines for PICU-based rehabilitation, but expressed interest in developing and implementing such guidelines; 2) despite this lack of guidelines, an overwhelming majority of respondents reported that their current practices would involve consultation of multiple rehabilitation services for each case example provided; 3) PICU physicians believed that additional research evidence is needed to determine efficacy and optimal implementation of PICU-based rehabilitation; 4) PICU physicians reported significant barriers to implementation of PICU-based rehabilitation across centers; and 5) low routine assessment of long-term functional outcomes of PICU patients, although some centers have developed multidisciplinary follow-up programs.

CONCLUSIONS

Physicians lack PICU-based rehabilitation guidelines despite great interest and current practices involving a high degree of PICU-based rehabilitation consultation. Data are needed to identify best practices and necessary resources in the delivery of ICU-based multidisciplinary rehabilitation and long-term functional outcomes assessment to optimize recovery of children and families affected by critical illness.

Associations of Participation-Focused Strategies and Rehabilitation Service Use With Caregiver Stress After Pediatric Critical Illness

OBJECTIVE(S)

Determine the associations between having participation-focused strategies and receiving rehabilitation services in the pediatric intensive care unit (PICU) with caregiver stress over 6 months post-PICU discharge.

DESIGN

Substudy of a data from Wee-Cover, a prospective cohort study.

SETTING

Two PICU sites.

PARTICIPANTS

Caregivers (N=168) of children 1-17 years old admitted into a PICU for ≥48 hours.

MAIN OUTCOME MEASURES

Data were collected from caregivers at enrollment and 3 and 6 months post-PICU discharge. Caregiver stress was assessed using the Pediatric Inventory for Parents. Having strategies to support their child's participation in home-based activities was assessed using the Participation and Environment Measure (PEM). In PEM, caregivers report on strategies used to support their child's participation in home-based activities. Data were dichotomized (yes, no) to denote having participation-focused strategies and if their child received PICU rehabilitation services. Additional covariates were history of a preexisting condition, child age, length of PICU stay, and change in functional capacities at PICU discharge.

RESULTS

History of a preexisting condition, time, and change in functional capacities significantly predicted caregiver stress frequency and difficulty. The interaction of having strategies-by-rehabilitation-by-time significantly predicted caregiver stress frequency and difficulty.

CONCLUSION(S)

Results highlight the role of early rehabilitation and the importance of working with caregivers to develop participation-focused strategies to support their child's functioning post-PICU. Families of children with a preexisting condition or those who experience a decrease in function during a PICU stay are susceptible to higher levels of stress and may be a priority population to target for rehabilitation services.

Early Mobilization in Critically Ill Children: A Systematic Review

OBJECTIVE

To characterize how early mobilization is defined in the published literature and describe the evidence on safety and efficacy on early mobilization in critically ill children.

STUDY DESIGN

Systematic search of randomized and nonrandomized studies assessing early mobilization-based physical therapy in critically ill children under 18 years of age in MEDLINE, Embase, CINAHL, CENTRAL, the National Institutes of Health, Evidence in Pediatric Intensive Care Collaborative, Physiotherapy Evidence Database, and the Mobilization-Network. We extracted data to identify the types of mobility-based interventions and definitions for early, as well as barriers, feasibility, adverse events, and efficacy outcomes (mortality, morbidities, and length of stay).

RESULTS

Of 1199 titles found, we included 11 studies (2 pilot trials and 9 observational studies) and 1 clinical practice guideline in the analyses. Neurodevelopmentally appropriate increasing mobility levels have been described for critically ill children, and "early" mobilization was defined as either a range (within 48-72 hours) from admission to the pediatric intensive care unit or when clinical safety criteria are met. Current evidence suggests that early mobilization is safe and feasible and institutional practice guidelines significantly increase the frequency of rehabilitation consults, improve the proportion of patients who receive early mobilization, and reduce the time to mobilization. However, there were inconsistencies in populations and interventions across studies, and imprecision and risk of bias in included studies that precluded us from pooling data to evaluate the efficacy outcomes of early mobilization.

CONCLUSIONS

The definition of early mobilization varies, but seems to be feasible and safe in critically ill children. The efficacy for early mobilization in this population is yet undetermined because of the low certainty of the evidence available.

Determinants of change in home participation among critically ill children

AIM

To estimate changes in home participation among critically ill children in the first 6 months after discharge from a pediatric intensive care unit (PICU), and to explore the effect of child, service, and environmental factors on change in home participation.

METHOD

This was a prospective bi-center, longitudinal cohort study. Caregivers of 180 children, aged 1 to 17 years, who were admitted into the PICU for at least 48 hours were included. Patient-reported outcomes were used to capture caregivers' perspectives of their child's participation and environmental supports for participation in home activities. Data were collected at enrollment, and 3 and 6 months after discharge.

RESULTS

There were no significant changes in home participation frequency or involvement, but involvement rates across time were moderated by functional status. Age significantly predicted participation frequency. Pre-PICU functional status and capabilities were significant predictors of participation frequency and involvement, and home environmental support significantly predicted home involvement.

INTERPRETATION

Results suggest relatively stable participation trajectories in the 6 months after PICU admission. Children with abnormal baseline function experienced a greater increase in home involvement after PICU. Rehabilitation interventions targeting functional capabilities and home environment may be viable approaches during the early phase of recovery. Environmental interventions may be more time-efficient after PICU stay and merit further study.

WHAT THIS PAPER ADDS

Children's pre-pediatric intensive care unit (PICU) functional status and capabilities impact their participation after critical illness. Children's trajectories of home involvement may differ over time based on their pre-PICU functional status. Caregiver perceptions of environmental support impact a child's home involvement after discharge from a PICU.

Random serum free cortisol and total cortisol measurements in pediatric septic shock

Background The aim of the study was to examine the relationship between serum total cortisol (TC) and free cortisol (FC) levels in children with septic shock and the relationship of these levels with baseline illness severity. Methods A sub-study of a randomized controlled trial (RCT) of hydrocortisone vs. placebo in pediatric septic shock conducted in seven academic pediatric intensive care units (PICUs) in Canada on children aged newborn to 17 years. Thirty children with septic shock had serum sent for TC and FC measurement within 6 h of meeting the study eligibility criteria. Results Baseline FC and TC levels were strongly correlated with baseline Pediatric Risk of Mortality (PRISM) score (R2=0.759, p<0.001; R2=0.717, p<0.001) and moderately correlated with admission Vasotropic Inotropic Score (VIS) (R2=0.489, p<0.001; R2=0.316, p<0.001). Serum TC levels were highly correlated with FC levels (R2=0.92, p<0.001) and showed strong agreement (R2=0.98, p<0.001 on a Bland-Altman plot). The ratio of FC to TC moderately correlated with TC levels (R2=0.46, p<0.001) but did not correlate with baseline albumin levels (R2=0.19, p=0.13). Conclusions Random TC and FC levels are strongly correlated, show strong agreement and are reflective of illness severity in children with septic shock. As such, isolated FC measurement does not appear to provide added information relative to TC in acutely ill children with septic shock.

Practice Recommendations for Early Mobilization in Critically Ill Children

Prolonged immobility is associated with significant short- and long-term morbidities in critically ill adults and children. The majority of critically ill children remain immobilized while in the pediatric intensive care unit (PICU) due to limited awareness of associated morbidities, lack of comfort and knowledge on how to mobilize critically ill children, and the lack of pediatric-specific practice guidelines. The objective of this article was to develop consensus practice recommendations for safe, early mobilization (EM) in critically ill children. A group of 10 multidisciplinary experts with clinical and methodological expertise in physical rehabilitation, EM, and pediatric critical care collaborated to develop these recommendations. First, a systematic review was conducted to evaluate existing evidence on EM in children. Using an iterative process, the working document was circulated electronically to panel members until the group reached consensus. The group agreed that the overall goals of mobilization are to reduce PICU morbidities and optimize recovery. EM should therefore not be instituted in isolation but as part of a rehabilitation care bundle. Mobilization should not be delayed, but its appropriateness and safety should be assessed early. Increasing levels of physical activity should be individualized for each patient with the goal of achieving the highest level of functional mobility that is developmentally appropriate, for increasing durations, daily. We developed a system-based set of clinical safety criteria and a checklist to ensure the safety of mobilization in critically ill children. Although there is a paucity of pediatric evidence on the efficacy of EM, there is ample evidence that prolonged bed rest is harmful and should be avoided. These EM practice recommendations were developed to educate clinicians, encourage safe practices, reduce PICU-acquired morbidities, until future pediatric research provides evidence on effective rehabilitation interventions and how best to implement these in critically ill children.

Performance Monitoring in Children Following Traumatic Brain Injury Compared to Typically Developing Children

Children with traumatic brain injury are reported to have deficits in performance monitoring, but the mechanisms underlying these deficits are not well understood. Four performance monitoring hypotheses were explored by comparing how 28 children with traumatic brain injury and 28 typically developing controls (matched by age and sex) performed on the stop-signal task. Control children slowed significantly more following incorrect than correct stop-signal trials, fitting the error monitoring hypothesis. In contrast, the traumatic brain injury group showed no performance monitoring difference with trial types, but significant group differences did not emerge, suggesting that children with traumatic brain injury may not perform the same way as controls.

Need for a Randomized Controlled Trial of Stress Ulcer Prophylaxis in Critically Ill Children: A Canadian Survey

BACKGROUND

Stress ulcer prophylaxis is commonly used in pediatric critical care, to prevent upper gastrointestinal bleeding. The most frequently used agents are histamine-2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs). The risk-benefit ratio for stress ulcer prophylaxis is uncertain, because data from randomized clinical trials (RCTs) on the effectiveness and harms of prophylaxis in children are limited.

OBJECTIVE

To describe the views of Canadian pediatric intensivists about a future RCT of stress ulcer prophylaxis.

METHODS

We conducted an online survey of Canadian pediatric critical care physicians. We e-mailed information about the study and a link to a 10-item survey to 111 potential respondents, with 2 reminders for nonrespondents. We assessed the relationship between respondents' characteristics and their views about the need for and potential participation in a trial using logistic regression and assessed regional differences using the χ² test.

RESULTS

The 68 physicians who replied (61% of potential respondents) had a median of 12 (interquartile range 5-20) years of experience. Forty-four (65%) of the respondents stated that a large, rigorous RCT of stress ulcer prophylaxis in children is needed, and 94% (62 of 66) indicated that it should include a placebo group. The 3 most common designs suggested were a 3-arm trial comparing PPI, H2RA, and placebo (56% [37 of 66 respondents to this question]) and 2-arm trials comparing PPI with placebo (15% [n = 10]) and H2RA with placebo (8% [n = 5]). The 5 patient groups that respondents most commonly stated should be excluded (because they should not receive placebo) were children receiving acid suppression at home (66% [42 of 64 respondents to this question]) or corticosteroids (59% [n = 38]), those with severe coagulopathy or receiving extracorporeal membrane oxygenation (both 36% [n = 23]), and those with burns (31% [n = 20]). Most respondents indicated a willingness to participate in an RCT (64% [42 of 66 respondents to this question]), whereas some (29% [n = 19]) indicated that participation would depend on trial design or funding; only 8% (n = 5) were disinclined to participate.

CONCLUSIONS

There is considerable interest in a placebo-controlled RCT of stress ulcer prophylaxis among pediatric critical care physicians in Canada, but consensus on key elements of the trial design is needed.

Brain biomarkers and pre-injury cognition are associated with long-term cognitive outcome in children with traumatic brain injury

Background

Children with traumatic brain injury (TBI) are frequently at risk of long-term impairments of attention and executive functioning but these problems are difficult to predict. Although deficits have been reported to vary with injury severity, age at injury and sex, prognostication of outcome remains imperfect at a patient-specific level. The objective of this proof of principle study was to evaluate a variety of patient variables, along with six brain-specific and inflammatory serum protein biomarkers, as predictors of long-term cognitive outcome following paediatric TBI.

Method

Outcome was assessed in 23 patients via parent-rated questionnaires related to attention deficit hyperactivity disorder (ADHD) and executive functioning, using the Conners 3rd Edition Rating Scales (Conners-3) and Behaviour Rating Inventory of Executive Function (BRIEF) at a mean time since injury of 3.1 years. Partial least squares (PLS) analyses were performed to identify factors measured at the time of injury that were most closely associated with outcome on (1) the Conners-3 and (2) the Behavioural Regulation Index (BRI) and (3) Metacognition Index (MI) of the BRIEF.

Results

Higher levels of neuron specific enolase (NSE) and lower levels of soluble neuron cell adhesion molecule (sNCAM) were associated with higher scores on the inattention, hyperactivity/impulsivity and executive functioning scales of the Conners-3, as well as working memory and initiate scales of the MI from the BRIEF. Higher levels of NSE only were associated with higher scores on the inhibit scale of the BRI.

Conclusions

NSE and sNCAM show promise as reliable, early predictors of long-term attention-related and executive functioning problems following paediatric TBI.

Maintenance vitamin D3 dosage requirements in Chinese women with post menopausal osteoporosis living in the tropics

BACKGROUND AND OBJECTIVES

Vitamin D3 (cholecalciferol) dose required to maintain sufficiency in non- Caucasian women with postmenopausal osteoporosis (PMO) inthe tropics has not been well studied. Some guidelines mandate 800-1000 IU vitamin D/day but the Endocrine Society (US) advocates 1500-2000 IU/day to maintain 25-hydroxyvitamin-D (25(OH)D) concentration at >75 nmol/L. We aimed to establish oral cholecalciferol dose required to maintain 25(OH)D concentration at >75 nmol/L in PMO Chinese Malaysian women, postulating lower dose requirements amongst light-skinned subjects in the tropics.

METHODS AND STUDY DESIGN

90 Chinese Malaysian PMO women in Kuala Lumpur, Malaysia (2°30'N) with baseline serum 25(OH)D levels >=50 nmol/L were recruited. Prior vitamin D supplements were discontinued and subjects randomized to oral cholecalciferol 25,000 IU/4-weekly (Group-A) or 50,000 IU/4-weekly (Group- B) for 16 weeks, administered under direct observation. Serum 25(OH)D, PTH, serum/urinary calcium were measured at baseline, 8 and 16 weeks.

RESULTS

Baseline characteristics, including osteoporosis severity, sun exposure (~3 hours/week), and serum 25(OH)D did not differ between treatment arms. After 16 weeks, 91% of women sufficient at baseline, remained sufficient on 25,000 IU/4-weekly compared with 97% on 50,000 IU/4-weekly with mean serum 25(OH)D 108.1±20.4 and 114.7±18.4 SD nmol/L respectively (p=0.273). At trial's end, 39% and 80% of insufficient women at baseline attained sufficiency in Group A and Group B (p=0.057). Neither dose was associated with hyperparathyroidism or toxicity.

CONCLUSIONS

Despite pretrial vitamin D supplementation and adequate sun exposure, 25.6% Chinese Malaysian PMO women were vitamin D insufficient indicating sunshine alone cannot ensure sufficiency in the tropics. Both ~900 IU/day and ~1800 IU/day cholecalciferol can safely maintain vitamin D sufficiency in >90% of Chinese Malaysian PMO women. Higher doses are required with baseline concentration <75 nmol/L.

Vasopressin in Pediatric Critical Care

Vasopressin is a unique hormone with complex receptor physiology and numerous physiologic functions beyond its well-known vascular actions and osmoregulation. While vasopressin has in the past been primarily used in the management of diabetes insipidus and acute gastrointestinal bleeding, an increased understanding of the physiology of refractory shock, and the role of vasopressin in maintaining cardiovascular homeostasis prompted a renewed interest in the therapeutic roles for this hormone in the critical care setting. Identifying vasopressin-deficient individuals for the purposes of assessing responsiveness to exogenous hormone and prognosticating outcome has expanded research into the evaluation of vasopressin and its precursor, copeptin as useful biomarkers. This review summarizes the current evidence for vasopressin in critically ill children, with a specific focus on its use in the management of shock. We outline important considerations and current guidelines, when considering the use of vasopressin or its analogues in the pediatric critical care setting.

A trial to determine whether septic shock-reversal is quicker in pediatric patients randomized to an early goal-directed fluid-sparing strategy versus usual care (SQUEEZE): study protocol for a pilot randomized controlled trial

BACKGROUND

Current pediatric septic shock resuscitation guidelines from the American College of Critical Care Medicine focus on the early and goal-directed administration of intravascular fluid followed by vasoactive medication infusions for persistent and fluid-refractory shock. However, accumulating adult and pediatric data suggest that excessive fluid administration is associated with worse patient outcomes and even increased risk of death. The optimal amount of intravascular fluid required in early pediatric septic shock resuscitation prior to the initiation of vasoactive support remains unanswered.

METHODS/DESIGN

The SQUEEZE Pilot Trial is a pragmatic, two-arm, parallel-group, open-label, prospective pilot randomized controlled trial. Participants are children aged 29 days to under 18 years with suspected or confirmed septic shock and a need for ongoing resuscitation. Eligible participants are enrolled under an exception to consent process and randomly assigned via concealed allocation to either the Usual Care (control) or Fluid Sparing (intervention) resuscitation strategy. The primary objective of this pilot trial is to determine feasibility, based on the ability to enroll participants and to adhere to the study protocol. The primary outcome measure by which success will be determined is participant enrollment rate ("pass" defined as at least two participants/site/month, recognizing that enrollment may be slower during the run-in phase). Secondary objectives include assessing (1) appropriateness of eligibility criteria, and (2) completeness of clinical outcomes to inform the endpoints for the planned multisite trial. To support the nested translational study, SQUEEZE-D, we will also evaluate the feasibility of describing cell-free DNA (a procoagulant molecule with prognostic utility) in blood samples obtained from children enrolled into the SQUEEZE Pilot Trial at baseline and at 24 h.

DISCUSSION

The optimal degree of fluid resuscitation and the timing of initiation of vasoactive support in order to achieve recommended therapeutic targets in children with septic shock remains unanswered. No prospective study to date has examined this important question for children in developed countries including Canada. Recruitment for the SQUEEZE Pilot Trial opened on 6 January 2014. Findings will inform the feasibility of the planned multicenter trial to answer our overall research question.

The RECOVER Program: Disability Risk Groups and 1-Year Outcome after 7 or More Days of Mechanical Ventilation

RATIONALE

Disability risk groups and 1-year outcome after greater than or equal to 7 days of mechanical ventilation (MV) in medical/surgical intensive care unit (ICU) patients are unknown and may inform education, prognostication, rehabilitation, and study design.

OBJECTIVES

To stratify patients for post-ICU disability and recovery to 1 year after critical illness.

METHODS

We evaluated a multicenter cohort of 391 medical/surgical ICU patients who received greater than or equal to 1 week of MV at 7 days and 3, 6, and 12 months after ICU discharge. Disability risk groups were identified using recursive partitioning modeling.

MEASUREMENTS AND MAIN RESULTS

The 7-day post-ICU Functional Independence Measure (FIM) determined the recovery trajectory to 1-year after ICU discharge and was an independent risk factor for 1-year mortality. The 7-day post-ICU FIM was predicted by age and ICU length of stay. By 2 weeks of MV, ICU patients could be stratified into four disability groups characterized by increasing risk for post ICU disability, ICU and post-ICU healthcare use, and disposition. Patients less than 42 years with ICU length of stay less than 2 weeks had the best function and fewest deaths at 1 year compared with patients greater than 66 years with ICU length of stay greater than 2 weeks who sustained the worst disability and 40% 1-year mortality. Depressive symptoms (17%) and post-traumatic stress disorder (18%) persisted at 1 year.

CONCLUSIONS

ICU survivors of greater than or equal to 1 week of MV may be stratified into four disability groups based on age and ICU length of stay. These groups determine 1-year recovery and healthcare use and are independent of admitting diagnosis and illness severity. Clinical trial registered with www.clinicaltrials.gov (NCT 00896220).

Outcomes Following Advanced Wound Care for Diabetic Foot Ulcers: A Canadian Study

OBJECTIVES

Data concerning outcomes of Canadian patients with diabetic foot ulcers (DFUs) are limited. The objectives of this study were to evaluate the healing rates and identify the predictors of poor outcomes following advanced wound care in patients presenting with DFUs.

METHODS

We conducted retrospective cohort study of adult patients who had DFUs and were referred to a single Canadian advanced diabetic foot and wound care centre between January 1, 2010, and December 31, 2010. The primary outcome was the healing rate at 52 weeks. The generalized estimating equation model was used to identify potential risk factors associated with delayed healing of DFUs.

RESULTS

Of the 40 patients for whom there were complete follow ups, 35 (87.5%) had healing of all DFUs by 52 weeks. Predictors of poor healing were the presence of chronic ulcers, ulcer sizes >1 cm², peripheral vascular disease and multiple ulcers at first presentation. Of the patients, 7.1% required amputation, and 8.9% of patients receiving our treatment died before 52 weeks. At 52 weeks of follow up, 16 of 17 recurrent ulcers and 68 of 108 pre-existing ulcers had healed. Compared to the unadjusted healing rate of preexisting ulcers (63.0%), the unadjusted healing rate of recurrent ulcers (94.1%) was significantly higher (p=0.01).

CONCLUSIONS

Our findings demonstrate that patients with DFUs in Canada who receive early and continued care from specialized, outpatient, advanced wound care centres experience significantly improved rates of healing of recurrent DFUs compared to pre-existing DFUs.
