Concise Definitive Review: In-Hospital Violence and Its Impact on Critical Care Practitioners.

OBJECTIVES: To provide a narrative review of hospital violence (HV) and its impact on critical care clinicians. DATA SOURCES: Detailed search strategy using PubMed and OVID Medline for English language articles describing HV, risk factors, precipitating events, consequences, and mitigation strategies. STUDY SELECTION: Studies that specifically addressed HV involving critical care medicine clinicians or their practice settings were selected. The time frame was limited to the last 15 years to enhance relevance to current practice. DATA EXTRACTION: Relevant descriptions or studies were reviewed, and abstracted data were parsed by setting, clinician type, location, social media events, impact, outcomes, and responses (agency, facility, health system, individual). DATA SYNTHESIS: HV is globally prevalent, especially in complex care environments, and correlates with a variety of factors including ICU stay duration, conflict, and has recently expanded to out-of-hospital occurrences; online violence as well as stalking is increasingly prevalent. An overlap with violent extremism and terrorism that impacts healthcare facilities and clinicians is similarly relevant. A number of approaches can reduce HV occurrence including, most notably, conflict management training, communication initiatives, and visitor flow and access management practices. Rescue training for HV occurrences seems prudent. CONCLUSIONS: HV is a global problem that impacts clinicians and imperils patient care. Specific initiatives to reduce HV drivers include individual training and system-wide adaptations. Future methods to identify potential perpetrators may leverage machine learning/augmented intelligence approaches.

Delphi Process for Validation of Fluid Treatment Algorithm for Critically Ill Pediatric Trauma Patients.

INTRODUCTION: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases. METHODS: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine. A three-round Delphi process was conducted via an online survey, with each round being followed by a live video conference. Experts agreed or disagreed with each aspect of the proposed fluid management algorithm on a five-level Likert scale. The group opinion level defined an algorithm parameter's acceptance or rejection with greater than 75% agreement resulting in acceptance and greater than 50% disagreement resulting in rejection. The remaining were discussed and re-presented in the next round. RESULTS: Fourteen experts from five Level 1 pediatric trauma centers representing three subspecialties were included. Responses were received from 13/14 participants (93%). In round 1, 64% of the parameters were accepted, while the remaining 36% were discussed and re-presented. In round 2, 90% of the parameters were accepted. Following round 3, there was 100% acceptance by all the experts on the revised and final version of the algorithm. CONCLUSIONS: We present a validated algorithm for intavenous fluid management in pediatric trauma patients that focuses on the de-escalation of fluids. Focusing on this time point of fluid therapy will help minimize iatrogenic complications of crystalloid fluids within this patient population.

Physical rehabilitation in Brazilian pediatric intensive care units: a multicenter point prevalence study.

OBJECTIVE: To determine the prevalence and factors associated with the physical rehabilitation of critically ill children in Brazilian pediatric intensive care units. METHODS: A 2-day, cross-sectional, multicenter point prevalence study comprising 27 pediatric intensive care units (out of 738) was conducted in Brazil in April and June 2019. This Brazilian study was part of a large multinational study called Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). The primary outcome was the prevalence of mobility provided by physical therapy or occupational therapy. Clinical data on patient mobility, potential mobility safety events, and mobilization barriers were prospectively collected in patients admitted for ≥ 72 hours. RESULTS: Children under the age of 3 years comprised 68% of the patient population. The prevalence of therapist-provided mobility was 74%, or 277 out of the 375 patient-days. Out-of-bed mobility was most positively associated with family presence (adjusted odds ratios 3.31;95%CI 1.70 - 6.43) and most negatively associated with arterial lines (adjusted odds ratios 0.16; 95%CI 0.05 - 0.57). Barriers to mobilization were reported on 27% of patient-days, the most common being lack of physician order (n = 18). Potential safety events occurred in 3% of all mobilization events. CONCLUSION: Therapist-provided mobility in Brazilian pediatric intensive care units is frequent. Family presence was high and positively associated with out-of-bed mobility. The presence of physiotherapists 24 hours a day in Brazilian pediatric intensive care units may have a substantial impact on the mobilization of critically ill children.

Implementation Science Research in Pediatric Critical Care Medicine.

OBJECTIVES: 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. DESIGN: 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. RESULTS: 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. CONCLUSIONS: 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.

Speech-language pathologist involvement in the paediatric intensive care unit.

PURPOSE: To measure the prevalence of speech-language pathologist (SLP) involvement and associated trends for critically ill children in United States (US) paediatric intensive care units (PICU) through secondary analysis of the Prevalence of Acute Rehab for Kids in the PICU (PARK-PICU) study data. METHOD: A secondary analysis of cross-sectional point prevalence study conducted over 1 day in 82 US PICUs. Data collected included SLP presence, patients' age, length of stay, medical interventions, aetiology, admission data, Glasgow Coma Scale scores, staffing involvement, and family presence. RESULT: Among 961 patients, 82 were visited by an SLP on the study day for a prevalence of 8.5%. Most visits were for children <3 years old. The odds of SLP involvement were lower for children who were 7-12 years old (vs. age 0-2; adjusted odds ratio [aOR] 0.28; 95% CI 0.1-0.8), were mechanically ventilated via endotracheal tube (vs. room air; aOR 0.02; 95% CI 0.005-0.11), or had mild or severe disability (mild vs. no disability; aOR 0.34; 95% CI 0.16-0.76 and severe vs. no disability; aOR 0.39; 95% CI 0.17-0.90). Concurrent physical and/or occupational therapy involvement was associated with higher odds of SLP involvement (aOR 3.6; 95% CI 2.1-6.4). CONCLUSION: SLP involvement is infrequent in US PICUs. PICU teams should be educated about the scope of SLP practice, to support communication and oral feeding needs during early recovery from critical illness.

Comfort and Coordination among Interprofessional Care Providers Involved in Intubations in the Pediatric Intensive Care Unit.

Background: Successful execution of invasive procedures in acute care settings, including tracheal intubation, requires careful coordination of an interprofessional team. The stress inherent to the intensive care unit (ICU) environment may threaten the optimal communication and planning necessary for the safe execution of this complex procedure. The objective of this study is to characterize the perceptions of interprofessional team members surrounding tracheal intubations in the pediatric ICU (PICU). Methods: This is a single-center survey-based study of staff involved in the intubation of pediatric patients admitted to a tertiary level academic PICU. Physicians, nurses, and respiratory therapists (RT) involved in tracheal intubations were queried via standardized, discipline-specific electronic surveys regarding their involvement in procedural planning and overall awareness of and comfort with the intubation plan. Qualitative variables were assessed by both Likert scales and free-text comments that were grouped and analyzed thematically. Results: One hundred and eleven intubation encounters were included during the study time period, of which 93 (84%) had survey responses from at least 2 professional teams. Among those included in the analysis, the survey was completed 244 times by members of the PICU teams including 86 responses from physicians, 76 from nurses, and 82 from RTs. Survey response rates were >80% from each provider team. There were significant differences in interprofessional team comfort with nurses feeling less well informed and comfortable with the intubation plan and process compared to physicians and RTs (p < 0.001 for both). Qualitative themes including clear communication, adequate planning and preparation prior to procedure initiation, and clear definition of roles emerged among both affirmative and constructive comments. Conclusions: Exploration of provider perceptions and emergence of constructive themes expose opportunities for teamwork improvement strategies involving intubations in the PICU. The use of a preintubation checklist may improve organization and communication amongst team members, increase provider morale, decrease team stress levels, and, ultimately, may improve patient outcomes during this high stakes, coordinated event.

Dendrimer nanotherapy targeting of glial dysfunction improves inflammation and neurobehavioral phenotype in adult female Mecp2-heterozygous mouse model of Rett syndrome.

Rett syndrome is an X-linked neurodevelopmental disorder caused by mutation of Mecp2 gene and primarily affects females. Glial cell dysfunction has been implicated in in Rett syndrome (RTT) both in patients and in mouse models of this disorder and can affect synaptogenesis, glial metabolism and inflammation. Here we assessed whether treatment of adult (5-6 months old) symptomatic Mecp2-heterozygous female mice with N-acetyl cysteine conjugated to dendrimer (D-NAC), which is known to target glia and modulate inflammation and oxidative injury, results in improved behavioral phenotype, sleep and glial inflammatory profile. We show that unbiased global metabolomic analysis of the hippocampus and striatum in adult Mecp2-heterozygous mice demonstrates significant differences in lipid metabolism associated with neuroinflammation, providing the rationale for targeting glial inflammation in this model. Our results demonstrate that treatment with D-NAC (10 mg/kg NAC) once weekly is more efficacious than equivalently dosed free NAC in improving the gross neurobehavioral phenotype in symptomatic Mecp2-heterozygous female mice. We also show that D-NAC therapy is significantly better than saline in ameliorating several aspects of the abnormal phenotype including paw clench, mobility, fear memory, REM sleep and epileptiform activity burden. Systemic D-NAC significantly improves microglial proinflammatory cytokine production and is associated with improvements in several aspects of the phenotype including paw clench, mobility, fear memory, and REM sleep, and epileptiform activity burden in comparison to saline-treated Mecp2-hetereozygous mice. Systemic glial-targeted delivery of D-NAC after symptom onset in an older clinically relevant Rett syndrome model shows promise in improving neurobehavioral impairments along with sleep pattern and epileptiform activity burden. These findings argue for the translational value of this approach for treatment of patients with Rett Syndrome.

RESUMO Objetivo: Determinar a prevalência e os fatores associados à reabilitação física de crianças em estado grave em unidades de terapia intensiva pediátrica brasileiras. Métodos: Realizou-se um estudo de prevalência pontual multicêntrico, transversal, de 2 dias, abrangendo 27 unidades de terapia intensiva pediátrica (do total de 738) no Brasil em abril e junho de 2019. Este estudo brasileiro fez parte de um grande estudo multinacional chamado Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). O desfecho primário foi a prevalência de mobilidade proporcionada pela fisioterapia ou pela terapia ocupacional. Foram coletados prospectivamente dados clínicos sobre a mobilidade do paciente, possíveis eventos de segurança de mobilidade e barreiras de mobilização em pacientes admitidos por ≥ 72 horas. Resultados: As crianças com idade inferior a 3 anos eram 68% da população de pacientes. A prevalência de mobilidade fornecida pelo terapeuta foi de 74%, ou 277 dos 375 pacientes-dia. A mobilidade para fora do leito foi mais positivamente associada à presença de familiares (razão de chance ajustada de 3,31; IC95% 1,70 - 6,43) e mais negativamente associada às linhas arteriais (razão de chance ajustada de 0,16; IC95% 0,05 - 0,57). Foram relatadas barreiras à mobilização em 27% dos pacientes-dia, sendo a mais comum a falta de prescrição médica (n = 18). Registaram-se eventuais eventos de segurança em 3% de todos os eventos de mobilização. Conclusão: A mobilidade proporcionada pelo terapeuta nas unidades de terapia intensiva pediátrica brasileiras é frequente. A presença de familiares foi alta e positivamente associada à mobilidade para fora do leito. A presença de fisioterapeutas 24 horas por dia nas unidades de terapia intensiva pediátrica brasileiras pode exercer papel importante na mobilização de crianças em estado grave.

Is Provider Training Level Associated with First Pass Success of Endotracheal Intubation in the Pediatric Intensive Care Unit?

Endotracheal intubation is a life-saving procedure in critically ill pediatric patients and a foundational skill for critical care trainees. Multiple intubation attempts are associated with increased adverse events and increased morbidity and mortality. Thus, we aimed to determine patient and provider factors associated with first pass success of endotracheal intubation in the pediatric intensive care unit (PICU). This prospective, single-center quality improvement study evaluated patient and provider factors associated with multiple intubation attempts in a tertiary care, academic, PICU from May 2017 to May 2018. The primary outcome was the number of tracheal intubation attempts. Predictive factors for first pass success were analyzed by using univariate and multivariable logistic regression analysis. A total of 98 intubation encounters in 75 patients were analyzed. Overall first pass success rate was 67% (66/98), and 7% (7/98) of encounters required three or more attempts. A Pediatric critical care medicine (PCCM) fellow was the first laryngoscopist in 94% (92/98) of encounters with a first pass success rate of 67% (62/92). Age of patient, history of difficult airway, provider training level, previous intubation experience, urgency of intubation, and time of day were not predictive of first pass success. First pass success improved slightly with increasing fellow year (fellow year = 1, 66%; fellow year = 2, 68%; fellow year = 3, 69%) but was not statistically significant. We identified no intrinsic or extrinsic factors associated with first pass intubation success. At a time when PCCM fellow intubation experience is at risk of declining, PCCM fellows should continue to take the first attempt at most intubations in the PICU.

The association of a scholarly concentrations program with medical students' matched residencies.

PURPOSE: Many medical school curricula include Scholarly Concentrations (SC) programs. While studies have examined how these programs affect students' future research involvement, the association of SC programs with students' specialty choices is uncertain. This study examines the SC program factors associated with congruence between the specialty focus of students' SC projects and the clinical specialty they matched into for residency. METHODS: The authors conducted a retrospective cohort study of all students participating in the SC program at Johns Hopkins University School of Medicine for graduating classes 2013-2020. They used data from program questionnaires to categorize students' specialty interests (baseline) and SC program experiences (post-program). The authors categorized each student's project into specialties according to their faculty mentors' primary appointments, abstracted student publications from SCOPUS, and abstracted residency program rankings from Doximity Residency Navigator. The authors used multivariable logistic regression to calculate adjusted odds ratios (aOR) for specialty-congruent matching (same specialty as SC project) and for matching into a Doximity-ranked top 20 or top 10 program. RESULTS: Overall, 35.3% of the 771 students matched into the same specialty as their SC projects. Increased odds of specialty-congruent matching occurred with 'definite' interest in the specialty at baseline [aOR (95% CI): 1.76 (0.98-3.15)] (P = 0.06) and with increasing publications with SC mentors [aOR (95% CI): 1.16 (1.03-1.30)] (P = 0.01). Congruence between SC specialty focus and matched specialty conferred no significant difference in odds of matching to a Doximity-ranked top 20 or top 10 program. CONCLUSIONS: Baseline certainty of specialty interest and research productivity were associated with specialty congruence. However, as completing an SC project in a given specialty was not associated with increased odds of matching into that specialty nor into a higher Doximity-ranked program, SC program directors should advise students to pursue SC projects in any topic of personal interest.

The Effects of Intraoperative Methadone on Postoperative Pain Control in Pediatric Patients: A Scoping Review.

Inadequate perioperative pain control has deleterious effects on children's development and can lead to heightened pain experiences and the avoidance of future medical procedures. Reports of perioperative use of methadone in children are increasing, as it has a favorable pharmacodynamic profile; however, the effectiveness of methadone in reducing postoperative pain has not been established. We, therefore, aimed to provide a scoping review of the literature comparing the effect of intraoperative methadone versus other opioids on postoperative opioid consumption, pain scores, and adverse events in pediatric patients. We identified studies in PubMed, Scopus, Embase, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases from inception to January 2023. Postoperative opioid consumption, pain scores, and adverse events were extracted for analysis. We screened 1864 studies, of which 83 studies were selected for full-text review. Five studies were included in the final analysis. Postoperative opioid consumption was decreased overall in children who received methadone compared to those who did not. The majority of studies indicated that methadone was superior to other opioids in reported pain scores, while the frequency of adverse events was similar between the groups. Although the data reviewed highlight a potential benefit of intraoperative methadone in pediatric patients, 4 of the 5 studies had serious methodological concerns. Thus, we cannot make strong recommendations for the regular use of methadone in the perioperative setting at this time. Our results highlight the need for large, well-designed randomized trials to fully evaluate the safety and efficacy of intraoperative methadone in diverse pediatric surgical populations.

Social Determinants of Health in Pediatric Rehabilitation for Children with Traumatic Injury: A Systematic Review.

OBJECTIVE: To examine the current evidence regarding health care disparities in pediatric rehabilitation after hospitalization with traumatic injury. STUDY DESIGN: This systematic review utilized both PubMed and EMBASE, and each was searched with key MESH terms. Studies were included in the systematic review if they (1) addressed social determinants of health including, but not limited to, race, ethnicity, insurance status, and income level; (2) focused on inpatient and outpatient rehabilitation services posthospital stay; (3) were based in the pediatric population; and (4) addressed traumatic injury requiring hospitalization. Only studies from within the US were included. RESULTS: From 10 169 studies identified, 455 abstracts were examined for full-text review, and 24 studies were chosen for data extraction. Synthesis of the 24 studies revealed 3 major themes: (1) access to services; (2) outcomes from rehabilitation; and (3) service provision. Patients with public insurance had decreased availability of service providers and had longer outpatient wait times. Non-Hispanic Black and Hispanic children were more likely to have greater injury severity and decreased functional independence after discharge. Lack of interpreter services was associated with decreased utilization of outpatient services. CONCLUSIONS: This systematic review identified significant effects of health care disparities on the rehabilitation process in pediatric traumatic injury. Social determinants of health must be thoughtfully addressed to identify key areas of improvement for the provision of equitable health care.

Caring for Critically Ill Children With the ICU Liberation Bundle (ABCDEF): Results of the Pediatric Collaborative.

OBJECTIVES: Assess clinical outcomes following PICU Liberation ABCDEF Bundle utilization. DESIGN: Prospective, multicenter, cohort study. SETTING: Eight academic PICUs. PATIENTS: Children greater than 2 months with expected PICU stay greater than 2 days and need for mechanical ventilation (MV). INTERVENTIONS: ABCDEF Bundle implementation. MEASUREMENT AND MAIN RESULTS: Over an 11-month period (3-mo baseline, 8-mo implementation), Bundle utilization was measured for 622 patients totaling 5,017 PICU days. Risk of mortality was quantified for 532 patients (4,275 PICU days) for correlation between Bundle utilization and MV duration, PICU length of stay (LOS), delirium incidence, and mortality. Utilization was analyzed as subject-specific (entire PICU stay) and day-specific (single PICU day). Median overall subject-specific utilization increased from 50% during the 3-month baseline to 63.9% during the last four implementation months ( p < 0.001). Subject-specific utilization for elements A and C did not change; utilization improved for B (0-12.5%; p = 0.007), D (22.2-61.1%; p < 0.001), E (17.7-50%; p = 0.003), and F (50-79.2%; p = 0.001). We observed no association between Bundle utilization and MV duration, PICU LOS, or delirium incidence. In contrast, on adjusted analysis, every 10% increase in subject-specific utilization correlated with mortality odds ratio (OR) reduction of 34%, p < 0.001; every 10% increase in day-specific utilization correlated with a mortality OR reduction of 1.4% ( p = 0.006). CONCLUSIONS: ABCDEF Bundle is applicable to children. Although enhanced Bundle utilization correlated with decreased mortality, increased utilization did not correlate with duration of MV, PICU LOS, or delirium incidence. Additional research in the domains of comparative effectiveness, implementation science, and human factors engineering is required to understand this clinical inconsistency and optimize PICU Liberation concept integration into clinical practice.

Impact of a multifaceted early mobility intervention for critically ill children - the PICU Up! trial: study protocol for a multicenter stepped-wedge cluster randomized controlled trial.

BACKGROUND: Over 50% of all critically ill children develop preventable intensive care unit-acquired morbidity. Early and progressive mobility is associated with improved outcomes in critically ill adults including shortened duration of mechanical ventilation and improved muscle strength. However, the clinical effectiveness of early and progressive mobility in the pediatric intensive care unit has never been rigorously studied. The objective of the study is to evaluate if the PICU Up! intervention, delivered in real-world conditions, decreases mechanical ventilation duration (primary outcome) and improves delirium and functional status compared to usual care in critically ill children. Additionally, the study aims to identify factors associated with reliable PICU Up! delivery. METHODS: The PICU Up! trial is a stepped-wedge, cluster-randomized trial of a pragmatic, interprofessional, and multifaceted early mobility intervention (PICU Up!) conducted in 10 pediatric intensive care units (PICUs). The trial's primary outcome is days alive free of mechanical ventilation (through day 21). Secondary outcomes include days alive and delirium- and coma-free (ADCF), days alive and coma-free (ACF), days alive, as well as functional status at the earlier of PICU discharge or day 21. Over a 2-year period, data will be collected on 1,440 PICU patients. The study includes an embedded process evaluation to identify factors associated with reliable PICU Up! delivery. DISCUSSION: This study will examine whether a multifaceted strategy to optimize early mobility affects the duration of mechanical ventilation, delirium incidence, and functional outcomes in critically ill children. This study will provide new and important evidence on ways to optimize short and long-term outcomes for pediatric patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT04989790. Registered on August 4, 2021.
