Like in many settings, implementation of evidence-based practices often fall short in pediatric intensive care units (PICU). Very few prior studies have applied implementation science frameworks to ...understand how best to improve practices in this unique environment. We used the relatively new integrated Promoting Action on Research Implementation in Health Services (iPARIHS) framework to assess practice improvement in the PICU and to explore the utility of the framework itself for that purpose.
We used the iPARIHS framework to guide development of a semi-structured interview tool to examine barriers, facilitators, and the process of change in the PICU. A framework approach to qualitative analysis, developed around iPARIHS constructs and subconstructs, helped identify patterns and themes in provider interviews. We assessed the utility of iPARIHS to inform PICU practice change.
Fifty multi-professional providers working in 8 U.S. PICUs completed interviews. iPARIHS constructs shaped the development of a process model for change that consisted of phases that include planning, a decision to adopt change, implementation and facilitation, and sustainability; the PICU environment shaped each phase. Large, complex multi-professional teams, and high-stakes work at near-capacity impaired receptivity to change. While the unit leaders made decisions to pursue change, providers' willingness to accept change was based on the evidence for the change, and provider's experiences, beliefs, and capacity to integrate change into a demanding workflow. Limited analytic structures and resources frustrated attempts to monitor changes' impacts. Variable provider engagement, time allocated to work on changes, and limited collaboration impacted facilitation. iPARIHS constructs were useful in exploring implementation; however, we identified inter-relation of subconstructs, unique concepts not captured by the framework, and a need for subconstructs to further describe facilitation.
The PICU environment significantly shaped the implementation. The described process model for implementation may be useful to guide efforts to integrate changes and select implementation strategies. iPARIHS was adequate to identify barriers and facilitators of change; however, further elaboration of subconstructs for facilitation would be helpful to operationalize the framework.

Difficulty in obtaining peripheral vascular access is a common problem in patients admitted to the pediatric intensive care unit (PICU). The use of ultrasound guidance can improve the overall success ...in obtaining vascular access. This study evaluated the success and longevity of PIV placement by nurses pre- and post-implementation of an USGPIV curriculum.
PICU nurses participated in a prospective quality improvement study. Each participating nurse attempted 10 PIVs by using landmark (LM) methods. The same nurses then received individual instruction in an USGPIV placement curriculum. Following the educational intervention, each nurse attempted 10 USGPIVs.
A total of 150 LM PIVs and 143 USGPIVs were attempted. The first stick success in the post-intervention (USGPIV) group was 85.9% compared to 47.3% in the pre-intervention (LM) group (p < 0.001). Overall success was also superior in the USGPIV group (94.3 versus 57.3%, respectively; p < 0.001). PIVs placed by US lasted longer with a median survival time of 4 ± 3.84 days versus 3 ± 3.51 days for LM PIVs (p < 0.050, log-rank test).
Successful implementation of a standardized curriculum for USGPIV placement for PICU nurses improves first stick, overall success, and longevity of PIV catheter placement.
An ultrasound-guided IV curriculum can be successfully implemented resulting in increased first stick success and increased longevity. Registered nurses can be trained in placement of ultrasound-guided IV placement. This study provides a training curriculum for ultrasound-guided IV placement that can be applied to other settings or institutions.

This article reviews an instrument used in cross-national research with dementia family caregivers-the Revised Scale for Caregiving Self-Efficacy (RSCSE). Although the RSCSE has been translated into ...multiple languages, few studies have examined scale performance across samples. We examine congruence of psychometric, reliability, and validity data to inform research and practice.
We conducted citation searches using Scopus, Google Scholar, Web of Science, and PsycINFO. Identified dementia caregiving studies cited the original RSCSE article and described results of English and/or non-English translations of the scale.
Peer-reviewed published studies (N = 58) of dementia family caregivers included data for Arabic, Chinese, English, French, Italian, and Spanish translations of the RSCSE; the majority (72%) reported use of non-English translations. Studies utilizing confirmatory factor analytic approaches reported findings consistent with the original development study. Internal consistency, convergent/discriminant validity, and criterion validity indices were congruent across diverse cross-national caregiving samples assessed with different translations. Data supported the RSCSE's sensitivity to change following specific psychosocial caregiving interventions.
The reliability and validity of different translations of the RSCSE support continued use with cross-national samples of dementia family caregivers. Limitations of the scale point to the need for further self-efficacy measurement development within caregiving domains. Consistent with Bandura's discussion of social cognitive theory in cultural contexts, personal agency for caregiving challenges remains generalizable to cross-national populations. This review discusses the implications for cross-cultural research and practice.
Guidelines recommend against RBC transfusion in hemodynamically stable (HDS) children without cardiac disease, if hemoglobin is greater than or equal to 7 g/dL. We sought to assess the clinical and ...economic impact of compliance with RBC transfusion guidelines.
A nonprespecified secondary analysis of noncardiac, HDS patients in the randomized trial Age of Blood in Children (NCT01977547) in PICUs. Costs analyzed included ICU stay and physician fees. Stabilized inverse propensity for treatment weighting was used to create a cohort balanced with respect to potential confounding variables. Weighted regression models were fit to evaluate outcomes based on guideline compliance.
Fifty international tertiary care centers.
Critically ill children 3 days to 16 years old transfused RBCs at less than or equal to 7 days of ICU admission. Six-hundred eighty-seven subjects who met eligibility criteria were included in the analysis.
Initial RBC transfusions administered when hemoglobin was less than 7 g/dL were considered "compliant" or "non-compliant" if hemoglobin was greater than or equal to 7 g/dL.
Frequency of new or progressive multiple organ system dysfunction (NPMODS), ICU survival, and associated costs. The hypothesis was formulated after data collection but exposure groups were masked until completion of planned analyses. Forty-nine percent of patients (338/687) received a noncompliant initial transfusion. Weighted cohorts were balanced with respect to confounding variables (absolute standardized differences < 0.1). No differences were noted in NPMODS frequency (relative risk, 0.86; 95% CI, 0.61-1.22; p = 0.4). Patients receiving compliant transfusions had more ICU-free days (mean difference, 1.73; 95% CI, 0.57-2.88; p = 0.003). Compliance reduced mean costs in ICU by $38,845 U.S. dollars per patient (95% CI, $65,048-$12,641).
Deferring transfusion until hemoglobin is less than 7 g/dL is not associated with increased organ dysfunction in this population but is independently associated with increased likelihood of live ICU discharge and lower ICU costs.
This article describes the methodology used for The Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2). The PALLIC-2 sought to develop evidence-based clinical recommendations and when ...evidence was lacking, expert-based consensus statements and research priorities for the diagnosis and management of pediatric acute respiratory distress syndrome (PARDS).
Electronic searches were conducted using PubMed, Embase, and Cochrane Library (CENTRAL) databases from 2012 to March 2022.
Content was divided into 11 sections related to PARDS, with abstract and full text screening followed by data extraction for studies which met inclusion with no exclusion criteria.
We used a standardized data extraction form to construct evidence tables, grade the evidence, and formulate recommendations or statements using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.
This consensus conference was comprised of a multidisciplinary group of international experts in pediatric critical care, pulmonology, respiratory care, and implementation science which followed standards set by the Institute of Medicine, using the GRADE system and Research And Development/University of California, Los Angeles appropriateness method, modeled after PALICC 2015. The panel of 52 content and four methodology experts had several web-based meetings over the course of 2 years. We conducted seven systematic reviews and four scoping reviews to cover the 11 topic areas. Dissemination was via primary publication listing all statements and separate supplemental publications for each subtopic that include supporting arguments for each recommendation and statement.
A consensus conference of experts from around the world developed recommendations and consensus statements for the definition and management of PARDS and identified evidence gaps which need further research.
Delay or failure to consistently adopt evidence-based or consensus-based best practices into routine clinical care is common, including for patients in the PICU. PICU patients can fail to receive ...potentially beneficial diagnostic or therapeutic interventions, worsening the burden of illness and injury during critical illness. Implementation science (IS) has emerged to systematically address this problem, but its use of in the PICU has been limited to date. We therefore present a conceptual and methodologic overview of IS for the pediatric intensivist.
The members of Excellence in Pediatric Implementation Science (ECLIPSE; part of the Pediatric Acute Lung Injury and Sepsis Investigators Network) represent multi-institutional expertise in the use of IS in the PICU. This narrative review reflects the collective knowledge and perspective of the ECLIPSE group about why IS can benefit PICU patients, how to distinguish IS from quality improvement (QI), and how to evaluate an IS article.
IS requires a shift in one's thinking, away from questions and outcomes that define traditional clinical or translational research, including QI. Instead, in the IS rather than the QI literature, the terminology, definitions, and language differs by specifically focusing on relative importance of generalizable knowledge, as well as aspects of study design, scale, and timeframe over which the investigations occur.
Research in pediatric critical care practice must acknowledge the limitations and potential for patient harm that may result from a failure to implement evidence-based or professionals' consensus-based practices. IS represents an innovative, pragmatic, and increasingly popular approach that our field must readily embrace in order to improve our ability to care for critically ill children.
In 2015, the Pediatric Acute Lung Injury Consensus Conference (PALICC) provided the first pediatric-specific definitions for acute respiratory distress syndrome (pediatric acute respiratory distress ...syndrome PARDS). These definitions have since been operationalized in cohort and interventional PARDS studies. As substantial data have accrued since 2015, we have an opportunity to assess the construct validity and utility of the initial PALICC definitions. Therefore, the Second PALICC (PALICC-2) brought together multiple PARDS experts and aimed to identify and summarize relevant evidence related to the definition and epidemiology of PARDS and create modifications to the definition of PARDS.
MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost).
We included studies of subjects with PARDS, or at risk for PARDS, excluding studies pertaining primarily to adults except as specified for identifying age-specific cutoffs.
Title/abstract review, full-text review, and data extraction using a standardized data collection form.
The Grading of Recommendations Assessment, Development, and Evaluation approach was used to identify and summarize evidence and develop recommendations. A total of 97 studies were identified for full-text extraction addressing distinct aspects of the PARDS definition, including age, timing, imaging, oxygenation, modes of respiratory support, and specific coexisting conditions. Data were assessed in a Patient/Intervention/Comparator/Outcome format when possible, and formally summarized for effect size, risk, benefit, feasibility of implementation, and equity. A total of 17 consensus-based definition statements were made that update the definition of PARDS, as well as the related diagnoses of "Possible PARDS" and "At-Risk for PARDS." These statements are presented alongside a summary of the relevant epidemiology.
We present updated, data-informed consensus statements on the definition for PARDS and the related diagnoses of "Possible PARDS" and "At-Risk for PARDS."
Background
The risks of red blood cell transfusion may outweigh the benefits for many patients in pediatric intensive care units (PICUs), but guidelines from the Transfusion and Anemia eXpertise ...Initiative (TAXI) have not been consistently adopted. We sought to identify factors that influenced transfusion decision‐making in PICUs to explore potential barriers and facilitators to implementing the guidelines.
Study Design and Methods
A total of 50 ICU providers working in eight US ICUs of different types (non‐cardiac PICUs, cardiovascular ICUs, combined units) and variable sizes (11–32 beds) completed semi‐structured interviews. Providers included ICU attendings and trainees, nurse practitioners, nurses, and subspecialty physicians. Interviews examined factors that influenced transfusion decisions, transfusion practices, and provider beliefs. Qualitative analysis utilized a Framework Approach. Summarized data was compared between provider roles and units with consideration to identify patterns and unique informative statements.
Results
Providers cited clinical, physiologic, anatomic, and logistic factors they considered in making transfusion decisions. Improving oxygen carrying capacity, hemodynamics and perfusion, respiratory function, volume deficits, and correcting laboratory values were among the reasons given for transfusion. Other sought‐after benefits included alleviating symptoms of anemia, improving ICU throughput, and decreasing blood waste. Providers in different roles approached transfusion decisions differently, with the largest differences noted between nurses and subspecialists as compared with other ICU providers. While ICU attendings most often made the decision to transfuse, all providers influenced the decision‐making.
Discussion
Implementation of transfusion guidelines requires multi‐professional approaches that emphasize the known risks of transfusion, its limited benefits, and highlight evidence around the safety and benefit of restrictive approaches.

RBC distribution width is reported to be an independent predictor of outcome in adults with a variety of conditions. We sought to determine if RBC distribution width is associated with morbidity or ...mortality in critically ill children.
Retrospective observational study.
Tertiary PICU.
All admissions to St. Louis Children's Hospital PICU between January 1, 2005, and December 31, 2012.
We collected demographics, laboratory values, hospitalization characteristics, and outcomes. We calculated the relative change in RBC distribution width from admission RBC distribution width to the highest RBC distribution width during the first 7 days of hospitalization. Our primary outcome was ICU mortality or use of extracorporeal membrane oxygenation as a composite. Secondary outcomes were ICU- and ventilator-free days.
We identified 3,913 eligible subjects with an estimated mortality (by Pediatric Index of Mortality 2) of 2.94% ± 9.25% and an actual ICU mortality of 2.91%. For the study cohort, admission RBC distribution width was 14.12% ± 1.89% and relative change in RBC distribution width was 2.63% ± 6.23%. On univariate analysis, both admission RBC distribution width and relative change in RBC distribution width correlated with mortality or the use of extracorporeal membrane oxygenation (odds ratio, 1.19 95% CI, 1.12-1.27 and odds ratio, 1.06 95% CI, 1.04-1.08, respectively; p < 0.001). After adjusting for confounding variables, including severity of illness, both admission RBC distribution width (odds ratio, 1.13; 95% CI, 1.03-1.24) and relative change in RBC distribution width (odds ratio, 1.04; 95% CI, 1.01-1.07) remained independently associated with ICU mortality or the use of extracorporeal membrane oxygenation. Admission RBC distribution width and relative change in RBC distribution width both weakly correlated with fewer ICU- (r = 0.038) and ventilator-free days (r = 0.05) (p < 0.001).
Independent of illness severity in critically ill children, admission RBC distribution width is associated with ICU mortality and morbidity. These data suggest that RBC distribution width may be a biomarker for RBC injury that is of sufficient magnitude to influence critical illness outcome, possibly via oxygen delivery impairment.
