Pediatric Critical Care Setting Research Articles

Determination, categorization, and hierarchy of content for a pediatric emergency medicine curriculum designed for emergency medicine residents.

Currently, the Accreditation Council of Graduate Medical Education requires time-based pediatric experiences for emergency medicine (EM) residents in both pediatric emergency medicine (PEM) and critical care settings. The American Board of Emergency Medicine has published the Model of the Clinical Practice of Emergency Medicine, which is a list of content an EM resident should learn. However, this list is large and without prioritization and therefore can be difficult to incorporate into time-limited curricula. The primary objective of this study was to develop comprehensive categorization of PEM content using an EM lens. The second objective was to suggest a prioritization for the EM learner of the enumerated PEM elements. We first assembled a comprehensive list of PEM concepts, diagnoses, and procedures that might be taught to EM residents. We then convened focus groups composed of key stakeholders to help formulate content and concept themes important for EM resident training. Once the themes were identified, we divided the list of PEM topics into appropriate themes and then carried out a second round of focus groups expanded to include more diverse expert input for prioritizing the elements of the comprehensive list within each theme. We prioritized 168 important PEM concepts from previous standards and emerging PEM literature among 10 identified themes: the pediatric normal, the bottom-line boil-it-down approach, common presentations, high-acuity pediatric cases and procedures, differences between children and adults, same between children and adults, red flags, infrequency of caring for a child compared with an adult, keep breadth but promote self-directed depth, and triage and disposition. Based on input from stakeholders in EM resident education, we identified key themes within PEM education and created a framework for the hierarchical categorization of PEM content for within an EM residency.

HOLISTIC ORAL CARE FOR CRITICALLY ILL CHILDREN: KNOWLEDGE AND PRACTICES OF INTENSIVE CARE UNIT NURSES

Objective: This research aims to assess the knowledge, perceptions, practices, and education of pediatric critical care nurses regarding oral care for critically ill children. The study addresses the existing gap in evidence-based oral care in this population and emphasizes the importance of understanding these factors for the development of effective oral hygiene practices in pediatric critical care settings. Methods: A descriptive cross-sectional study was conducted between October 2022 and March 2023 in Babylon Governorate. Four hospitals located in Hillah City, Babylon Province, were selected as the study sites. The sample included nurses working in specific critical care units within these hospitals, with a total of 170 nursing personnel participating. Data collection involved the distribution of questionnaires to the nurses, and statistical analysis was performed using SPSS software. The study obtained the necessary administrative and ethical approvals for data collection. Results: The sample consisted of 170 intensive care unit nurses, selected through stratified sampling based on gender (105 female and 65 male). Recruitment for the study commenced in February 2023. The mean score for oral health knowledge was moderate (2.14), However, the oral care practice score was good (2.02). No significant differences were observed in comprehensive mouth care scores based on age and educational qualification. Nevertheless, a significant difference was found in the mean score for complete oral care between male and female nurses (18.37 vs. 17.85, p = 0.021). Moreover, knowledge and practice scores varied significantly based on years of experience. Conclusions: This study provides valuable insights into the knowledge, perceptions, and practices of intensive care unit nurses regarding oral care. Implementation of standardized oral care protocols, along with adequate resources and support, can contribute to enhancing comprehensive mouth care in intensive care units.

Comparing the Quality of Domain-Specific Versus General Language Models for Artificial Intelligence-Generated Differential Diagnoses in PICU Patients.

Generative language models (LMs) are being evaluated in a variety of tasks in healthcare, but pediatric critical care studies are scant. Our objective was to evaluate the utility of generative LMs in the pediatric critical care setting and to determine whether domain-adapted LMs can outperform much larger general-domain LMs in generating a differential diagnosis from the admission notes of PICU patients. Single-center retrospective cohort study. Quaternary 40-bed PICU. Notes from all patients admitted to the PICU between January 2012 and April 2023 were used for model development. One hundred thirty randomly selected admission notes were used for evaluation. None. Five experts in critical care used a 5-point Likert scale to independently evaluate the overall quality of differential diagnoses: 1) written by the clinician in the original notes, 2) generated by two general LMs (BioGPT-Large and LLaMa-65B), and 3) generated by two fine-tuned models (fine-tuned BioGPT-Large and fine-tuned LLaMa-7B). Differences among differential diagnoses were compared using mixed methods regression models. We used 1,916,538 notes from 32,454 unique patients for model development and validation. The mean quality scores of the differential diagnoses generated by the clinicians and fine-tuned LLaMa-7B, the best-performing LM, were 3.43 and 2.88, respectively (absolute difference 0.54 units [95% CI, 0.37-0.72], p < 0.001). Fine-tuned LLaMa-7B performed better than LLaMa-65B (absolute difference 0.23 unit [95% CI, 0.06-0.41], p = 0.009) and BioGPT-Large (absolute difference 0.86 unit [95% CI, 0.69-1.0], p < 0.001). The differential diagnosis generated by clinicians and fine-tuned LLaMa-7B were ranked as the highest quality in 144 (55%) and 74 cases (29%), respectively. A smaller LM fine-tuned using notes of PICU patients outperformed much larger models trained on general-domain data. Currently, LMs remain inferior but may serve as an adjunct to human clinicians in real-world tasks using real-world data.

Cardiac point-of-care ultrasound: Practical integration in the pediatric and neonatal intensive care settings.

Cardiac point-of-care ultrasound (POCUS) is a technology increasingly leveraged at the bedside by pediatric criticalcare and neonatology providers to identify real-time hemodynamic pathophysiology. We present a framework for (1)identifying the scope of cardiac POCUS within the clinical practice setting, (2) standardizing views for protocolizedhemodynamic assessment relevant to pediatric critical illness and (3) integrating POCUS findings for therapeuticguidance. Within the review, we also discuss practical strengths and limitations to image acquisition andinterpretation within the varied cardiac POCUS views. Finally, we explore unique considerations within the neonatalpopulation. Conclusion: Cardiac POCUS is a technology and tool that reveals important real-time information at the bedside of the criticallyill child and infant. Understanding strengths and limitations of cardiac POCUS views and protocolizing an approachto answer focused clinical questions provides a framework for training and translation to clinical care. What is Known: • Ultrasound technology is now ubiquitous among pediatric critical care and neonatology settings, and growing literature supports an expanded role in not only procedural but also diagnostic applications. • Cardiac POCUS influences provider perception of pathophysiology and changes clinical management. What is New: • Effective cardiac POCUS training and subsequent translation to clinical practice should improve when clinical questions and protocolized approaches to image acquisition are standardized within a specialty. • Cardiac POCUS views have strengths and limitations which must be recognized when assessing the hemodynamic profile of a child or neonate.

1706. Risk factors for infections caused by extended spectrum beta lactamase (ESBL) producing and Carbapenem-resistant Enterobacterales (CRE) in pediatric critical care settings: A case control study

Abstract Background Infections due to Gram negative resistant bacterial pathogens are a major concern in intensive care units. The purpose of this study is to determine the risk factors for developing ESBL-producing and CRE infections in pediatric patients in critical care settings (PICU and NICU). Methods A retrospective case control study of infections due to ESBL-producing and CRE during a 5-year period (2016-2021) at Children’s Hospital of Michigan, Detroit. All patients had positive cultures during their PICU/NICU stay. Control cases were matched for age, infection site and year of infection but their cultures grew Enterobacterales that were non-ESBL or carbapenemase producers. Results A total of 58 patients with ESBL/Carbapenemase-producing Enterobacterales (cases) and 59 control patients were included. Majority of organisms were E. coli and Klebsiella species recovered from respiratory tract. There was no difference in both groups in regards to age, gender, race or length of hospital stay (p &amp;gt;0.3). There was no difference in prior hospital admission, PICU or NICU stay during the previous 6 months, indwelling devices, comorbid conditions, or surgery in the last 6 months (p &amp;gt;0.3). However, the presence of gastrostomy tube was more frequent in the cases group (29.3%) than the control group (15.3%) (p=0.078). Risk factors by univariate analysis included history of antibiotic use in last 6 months (93% in cases vs 73% in controls; p=0.006), cephalosporins use &amp;gt; 14 days (67% vs 31.2%; p=0.006),Trimethoprim/Sulfamethoxazole treatment duration &amp;gt; 14 days (11.1% vs 0%; p=0.012), carbapenem treatment duration &amp;gt; 14 days (14% vs 1.9%; p=0.027), and vancomycin use &amp;gt; 14 days (43.6% vs 21.6%; p=0.053). However, multivariate logistic regression analysis showed that antibiotic usage in the last 6 months was the single best predictor for cases with odds ratio of 5.02-fold (95% CI 1.56-16.13) (p=0.007). Conclusion Prior broad spectrum antibiotic usage was significantly associated with acquisition of ESBL and carbapenemase producing Enterobacterales. The study further underscores the need for optimizing antimicrobial stewardship practices to limit unnecessary and prolonged use of antibiotics to prevent the emergence of resistant pathogens.

Risk factors and outcomes associated with unplanned intraoperative extubation of the pediatric surgical patient: An analysis of the NSQIP-P database.

Unplanned intraoperative extubation is a rare but potentially catastrophic safety event. Inadvertent extubation in the neonatal and pediatric critical care setting is a recognized quality improvement metric whereas literature for intraoperative extubation is scarce. The aim of this study was to identify risk factors and outcomes associated with unplanned intraoperative extubation. We queried the National Surgical Quality Improvement Program-Pediatric database from 2019 to 2020 for patients <18 years of age. A total of 253 673 patients were included in the analysis. Associations between demographics, clinical variables, and unplanned intraoperative extubation were evaluated with univariable and multivariable logistic regression models. The primary outcome was unplanned intraoperative extubation. Secondary outcomes were postoperative pulmonary complication, unplanned reintubation within 24 h, cardiac arrest on day of surgery, and surgical site infection. Unplanned intraoperative extubation occurred in 163 (0.06%) patients. Specific procedures experienced unplanned intraoperative extubation at a higher rate such as bilateral cleft lip repair (1.31% of procedure type) and thoracic repair of tracheoesophageal fistula (1.11% of procedure type). Age, operative time (z-score), American Society of Anesthesiologists Classification 3 and 4, neurosurgery, plastic surgery, thoracic surgery, otolaryngology, and structural pulmonary/airway abnormalities were independent risk factors. Unplanned intraoperative extubation was associated with an increased unadjusted risk for postoperative pulmonary complication (p < .005; OR, 6.05; 95% confidence interval [CI]: 1.93-14.44), unplanned reintubation within 24 h (p < .005; OR, 8.41; 95% CI: 2.08-34.03), cardiac arrest on day of surgery (p < .05; OR, 22.67; 95% CI: 0.56-132.35), and surgical site infection (p < .0005; OR, 3.27; 95% CI 1.74-5.67). Unplanned intraoperative extubation occurs at a higher frequency in a subset of procedures and patient types. Identifying and targeting at-risk patients with preventative measures may decrease the incidence of unplanned intraoperative extubation and its associated outcomes.

Presentations and outcomes of familial hemophagocytic lymphohistiocytosis in the pediatric intensive care units (PICUs).

We aimed to describe Familial Hemophagocytic Lymphohistiocytosis (F-HLH) patients' clinical features, intensive care courses, and outcomes. Multi-center retrospective cohort study of pediatric patients diagnosed with F-HLH from 2015 to 2020 in five tertiary centers in Saudi Arabia. Patients were classified as F-HLH based on their genetic confirmation of known mutation or on their clinical criteria, which include a constellation of abnormalities, early disease onset, recurrent HLH in the absence of other causes, or a family history of HLH. Fifty-eight patients (28 male, 30 female), with a mean age of 21.0 ± 33.9 months, were included. The most common principal diagnosis was hematological or immune dysfunction (39.7%), followed by cardiovascular dysfunction in 13 (22.4%) patients. Fever was the most common clinical presentation in 27.6%, followed by convulsions (13.8%) and bleeding (13.8%). There were 20 patients (34.5%) who had splenomegaly, and more than 70% of patients had hyperferritinemia >500 mg/dl, hypertriglyceridemia >150 mg/dl and hemophagocytosis in bone marrow biopsy. Compared to deceased patients 18 (31%), survivors had significantly lower PT (p = 041), bilirubin level of <34.2 mmol/L (p = 0.042), higher serum triglyceride level (p = 0.036), and lesser bleeding within the initial 6 h of admission (p = 0.004). Risk factors for mortality included requirements of higher levels of hemodynamic (61.1% vs. 17.5%, p = 0.001) and respiratory (88.9% vs. 37.5%, p < 0.001) support, and positive fungal cultures (p = 0.046). Familial HLH still represents a challenge in the pediatric critical care setting. Earlier diagnosis and prompt initiation of appropriate treatment could improve F-HLH survival.

639: PREVALENCE OF ADVERSE SOCIAL DETERMINANTS OF HEALTH IN THE PEDIATRIC INTENSIVE CARE UNIT

Introduction: Social determinants of health (SDH) such as food security, housing, transportation and education have been linked to poor health, increased risk of chronic diseases, and unnecessary emergency department visits and hospitalizations. Screening for adverse SDH is routinely performed in pediatric outpatients and demonstrates a prevalence of 20%. The aim of this study was to determine the prevalence and characteristics of adverse SDH in patients admitted in a pediatric critical care setting. We hypothesized that the prevalence would be higher than in the outpatient setting. Methods: This is a single center prospective observational study of patients admitted to the Pediatric Intensive and Intermediate Care Units at a tertiary care children’s hospital with a Level 1 Trauma Center. Families were screened using the THRIVE screen, a validated, self-administered tool that assesses social needs that impact a patient’s healthcare. The tool was translated into Spanish, Haitian Creole and Portuguese. The nursing staff distributed forms to families at the time of admission. Families who identified adverse SDH had the option to receive resources from social workers. Results: Overall, 218 families were screened during the study. Of these, 75 families (34%) reported at least 1 unmet social need; of these, 44 (59%) requested more education and 35 (47%) requested resources. Of those that reported at least one need, the median number of needs was 2 (IQR 1-3). The most common need was food (53%), followed by employment (36%), medications (24%), utilities (23%), housing (21%), transportation (17%), and caregiving (5%). Of those that requested resources, the most common requested resource was food (47%). 8 (4%) of the forms returned were in a language other than English. There were no significant differences in the number of needs among English-speaking and non-English speaking families. Conclusions: Compared to pediatric outpatients, there is a higher prevalence of families with adverse SDH in the pediatric critical care setting. Food insecurity is particularly prevalent. Identifying and addressing these needs has the potential to provide more individualized care, improve clinical outcomes, and reduce readmission rates. Future studies should correlate unmet social needs with clinical outcomes such as length of stay.

Novel Coagulation Test Detects Anticoagulation Resistance and Is Associated With Thrombotic Events in Pediatric Patients Requiring Extracorporeal Membrane Oxygenation.

OBJECTIVES:Bivalirudin, an IV direct thrombin inhibitor, and unfractionated heparin (UFH) are frequently used anticoagulants in the pediatric critical care setting. An accurate, specific, point-of-care test to quantify and detect anticoagulation resistance is not currently available. This study evaluates the ability of a rapid (< 10 min), micro-volume (< 50 uL) coagulation test to detect and quantify the anticoagulation effect of bivalirudin and UFH using a functional, clot time endpoint in pediatric critical care patients.DESIGN:Single-site retrospective laboratory sample analysis and chart review.SETTING:A 105-bed pediatric and cardiac ICUs delivering extracorporeal membrane oxygenation.SUBJECTS:Forty-one citrated, frozen, biobanked plasma specimens comprising 21 with bivalirudin and 20 with UFH from 15 anticoagulated pediatric patients were analyzed. Thirteen patients were on extracorporeal membrane oxygenation, one had a submassive pulmonary embolism, and one was on a left ventricular assist device.INTERVENTIONS:None.MEASUREMENT AND MAIN RESULTS:A Clotting Time Score (CTS) was derived on each sample. The CTS detected patients that had developed a pathologic clotting event with 100% sensitivity and 82% specificity compared with prothrombin time with 25% sensitivity/76% specificity and activated partial thromboplastin time with 0% sensitivity/0% specificity. Additionally, the CTS detected subtherapeutic anticoagulation in response to UFH in patients that were clinically determined to be UFH resistant requiring alternative anticoagulation with bivalirudin.CONCLUSIONS:The CTS appears to be a clinically valuable indicator of coagulation status in patients treated with either UFH or bivalirudin. Results outside of the therapeutic range due to inadequate dosing or anticoagulation resistance appeared to be associated with clot formation. CTS testing may reduce the risk of anticoagulation-related complications via the rapid identification of patients at high risk for pathologic thrombotic events.

Dexmedetomidine in Children on Extracorporeal Membrane Oxygenation: Pharmacokinetic Data Exploration Using Previously Published Models.

BackgroundDexmedetomidine is a sedative and analgesic increasingly used in children supported with extracorporeal membrane oxygenation (ECMO). No data is available to describe the pharmacokinetics (PK) of dexmedetomidine in this population.MethodsWe performed a single-center prospective PK study. Children <18 years old, supported with ECMO, and on a dexmedetomidine infusion as part of their management were prospectively included. PK samples were collected. Dexmedetomidine dosing remained at the discretion of the clinical team. Six population PK models built in pediatrics were selected. Observed concentrations were compared with population predicted concentrations using the PK models.ResultsEight children contributed 30 PK samples. None of the PK models evaluated predicted the concentrations with acceptable precision and bias. Four of the six evaluated models overpredicted the concentrations. The addition of a correction factor on clearance improved models' fit. Two of the evaluated models were not applicable to our whole population age range because of their structure.ConclusionMost of the evaluated PK models overpredicted the concentrations, potentially indicating increased clearance on ECMO. Population PK models applicable to a broad spectrum of ages and pathologies are more practical in pediatric critical care settings but challenging to develop.

Italian Version of the Cornell Assessment of Pediatric Delirium: Evaluation of the Scale Reliability and Ability to Detect Delirium Compared to Pediatric Intensive Care Unit Physicians Clinical Evaluation

BackgroundDelirium is an acute brain dysfunction associated with increased length of hospitalization, mortality, and high healthcare costs especially in patients admitted to the pediatric intensive care unit (PICU). The Cornell Assessment of Pediatric Delirium (CAPD) is a screening tool for evaluating delirium in pediatric patients. This tool has already been used and validated in other languages but not in Italian.ObjectivesTo test the reliability of the Italian version of the CAPD to screen PICU patients for delirium and to assess the agreement between CAPD score and PICU physician clinical evaluation of delirium.MethodsProspective double-blinded observational cohort study of patients admitted to a tertiary academic center PICU for at least 48 h from January 2020 to August 2021. We evaluated intra- and inter-rater agreement using the Intraclass Correlation Coefficient (ICC). The ability of the scale to detect delirium was evaluated by comparing the nurses’ CAPD assessments with the clinical evaluation of a PICU physician with expertise in analgosedation using the area under the ROC curve (AUC).Measurements and Main ResultsSeventy patients were included in the study. The prevalence of pediatric delirium was 54% (38/70) when reported by a positive CAPD score and 21% (15/70) when diagnosed by the PICU physician. The CAPD showed high agreement levels both for the intra-rater (ICC 1 0.98, 95% CI: 0.97–0.99) and the inter-rater (ICC 2 0.93, 95% CI: 0.89–0.96) assessments. In patients with suspected delirium according to the CAPD scale, the observed sensitivity and specificity of the scale were 0.93 (95% CI: 0.68–1.00) and 0.56 (95% CI: 0.42–0.70), respectively. The AUC observed was 0.75 (95% CI: 0.66–0.8490).ConclusionThe Italian version of the CAPD seems a reliable tool for the identification of patients at high risk of developing delirium in pediatric critical care settings. Compared to the clinical evaluation of the PICU physician, the use of the CAPD scale avoids a possible underestimation of delirium in the pediatric population.

Intravenous maintenance fluid therapy practice in the pediatric acute and critical care settings: a European and Middle Eastern survey.

The ideal fluid for intravenous maintenance fluid therapy (IV-MFT) in acutely and critically ill children is controversial, and evidence-based clinical practice guidelines are lacking and current prescribing practices remain unknown. We aimed to describe the current practices in prescribing IV-MFT in the context of acute and critically ill children with regard to the amount, tonicity, composition, use of balanced fluids, and prescribing strategies in various clinical contexts. A cross-sectional electronic 27-item survey was emailed in April-May 2021 to pediatric critical care physicians across European and Middle East countries. The survey instrument was developed by an expert multi-professional panel within the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). A total of 154 respondents from 35 European and Middle East countries participated (response rate 64%). Respondents were physicians in charge of acute or critically ill children. All respondents indicated they routinely use a predefined formula to prescribe the amount of IV-MFT and considered fluid balance monitoring very important in the management of acute and critically ill children. The use of balanced solution was preferred if there were altered serum sodium and chloride levels or metabolic acidosis. Just under half (42%, 65/153) of respondents believed balanced solutions should always be used. Respondents considered the use of isotonic IV solutions as important for acute and critically ill children. In terms of the indication and the composition of IV-MFT prescribed, responses were heterogeneous among centers. Almost 70% (107/154) respondents believed there was a gap between current practice and what they considered ideal IV-MFT due to a lack of guidelines and inadequate training of healthcare professionals. Conclusions: Our study showed considerable variability in clinical prescribing practice of IV-MFT in acute pediatric settings across Europe and the Middle East. There is an urgent need to develop evidence-based guidelines for IV-MFT prescription in acute and critically ill children. What is Known: •The administration of maintenance intravenous fluid therapy is a standard of care for a lot of hospitalized children •Maintenance intravenous fluid therapy prescriptions are often based on Holliday and Segar's historical guidelines even if this practice has been associated with several complications. What is New: •This study provided information on the prescribing practice regarding fluid restriction, fluid tonicity, and balance. •This study showed considerable variability in clinical prescribing practice of intravenous maintenance fluid therapy across Europe and the Middle East.

Risk factors for central venous catheter-associated deep venous thrombosis in pediatric critical care settings identified by fusion model

BackgroundAn increase in the incidence of central venous catheter (CVC)-related thrombosis (CRT) has been reported in pediatric intensive care patients over the past decade. Risk factors for the development of CRT are not well understood, especially in children. The study objective was to identify potential clinical risk factors associated with CRT with novel fusion machine learning models.MethodsPatients aged 0–18 who were admitted to intensive care units from December 2015 to December 2018 and underwent at least one CVC placement were included. Two fusion model approaches (stacking and blending) were used to build a better performance model based on three widely used machine learning models (logistic regression, random forest and gradient boosting decision tree). High-impact risk factors were identified based on their contribution in both fusion artificial intelligence models.ResultsA total of 478 factors of 3871 patients and 3927 lines were used to build fusion models, one of which achieved quite satisfactory performance (AUC = 0.82, recall = 0.85, accuracy = 0.65) in 5-fold cross validation. A total of 11 risk factors were identified based on their independent contributions to the two fusion models. Some risk factors, such as D-dimer, thrombin time, blood acid-base balance-related factors, dehydrating agents, lymphocytes and basophils were identified or confirmed to play an important role in CRT in children.ConclusionsThe fusion model, which achieves better performance in CRT prediction, can better understand the risk factors for CRT and provide potential biomarkers and measures for thromboprophylaxis in pediatric intensive care settings.

Optic Nerve Sheath Diameter Ultrasound: A Non-Invasive Approach to Evaluate Increased Intracranial Pressure in Critically Ill Pediatric Patients.

Early diagnosis of increased intracranial pressure (ICP) is crucial for prompt diagnosis and treatment of intracranial hypertension in critically ill pediatric patients, preventing secondary brain damage and mortality. Although the placement of an external ventricular drain coupled to an external fluid-filled transducer remains the gold standard for continuous ICP monitoring, other non-invasive approaches are constantly being improved and can provide reliable estimates. The use of point-of-care ultrasound (POCUS) for the assessment of ICP has recently become widespread in pediatric emergency and critical care settings, representing a valuable extension of the physical examination. The aim of this manuscript is to review and discuss the basic principles of ultra-sound measurement of the optic nerve sheath diameter (ONSD) and summarize current evidence on its diagnostic value in pediatric patients with ICP. There is increasing evidence that POCUS measurement of the ONSD correlates with ICP, thus appearing as a useful extension of the physical examination in pediatrics, especially in emergency medicine and critical care settings for the initial non-invasive assessment of patients with suspected raised ICP. Its role could be of value even to assess the response to therapy and in the follow-up of patients with diagnosed intracranial hypertension if invasive ICP monitoring is not available. Further studies on more homogeneous and extensive study populations should be performed to establish ONSD reference ranges in the different pediatric ages and to define cut-off values in predicting elevated ICP compared to invasive ICP measurement.

Evaluating the Feasibility and Efficacy of a Pediatric Intensive Care Unit Diary.

As the progress of critical care medicine has improved the survival rate of critically ill patients, comorbidities and long-term health care have attracted people's attention. The terms "post-intensive care syndrome" (PICS) and "PICS-family" (PICS-F) have been used in non-neurocritical care populations, which are characterized by the cognitive, psychiatric, and physical sequelae associated with intensive care hospitalization of survivors and their families. An intensive care unit (ICU) diary authored by the patient's family members may alleviate the psychological distress of the patient and his or her family. This quality improvement project focused on the development and implementation of the pediatric intensive care unit (PICU) diary in the pediatric critical care setting. The project aims to evaluate the feasibility and the potential efficacy of the PICU diary, measured through parental acceptance and satisfaction. Seventeen families of critically ill children admitted to the PICU received the PICU diary during the implementation period. Twenty-four parents completed the weekly follow-up, and 15 subsequently completed the diary entry evaluation. The use of the diary in the PICU setting is feasible and considered beneficial by families of critically ill children.

Quality Improvement Initiative in Pediatric Critical Care

In a large academic pediatric medical center the formation of specialty care teams in the pediatric critical care setting led to the improvement in quality delivered to patients who had tracheostomies. Through frontline staff participation and interdisciplinary leadership – the team developed and strengthened processes that led to implementation of improvement strategies aimed at reducing hospital acquired pressure injury and decannulations. During this two-year time 150 nursing surveys and comprehensive literature reviews were completed to identify best practices and essential learning needs of the staff. The outcomes of these reviews helped to create improvement strategies which included developing educational initiatives focused on to support specific pathophysiologic issues impacting morbidity of patients leading to the quality metric goals. Upon completion of the educational and training initiatives led by the specialty care team, the incidence in tracheostomy decannulations and pressure injuries reduced significantly. Conclusions from this work highlight the importance of frontline staff as pivotal leaders in process change management and quality improvement changes. The teamwork among the interdisciplinary members allowed for enhanced collaboration in improving patient care outcomes and remains an active forum for evaluation of improvement in patient care. The efforts of the specialty care team provided sufficient data to support the implementation of specialty care teams that align efforts with that of organizational goals and aimed at reducing patient harm.

Prediction of central venous catheter-associated deep venous thrombosis in pediatric critical care settings

BackgroundAn increase in the incidence of central venous catheter (CVC)-associated deep venous thrombosis (CADVT) has been reported in pediatric patients over the past decade. At the same time, current screening guidelines for venous thromboembolism risk have low sensitivity for CADVT in hospitalized children. This study utilized a multimodal deep learning model to predict CADVT before it occurs.MethodsChildren who were admitted to intensive care units (ICUs) between December 2015 and December 2018 and with CVC placement at least 3 days were included. The variables analyzed included demographic characteristics, clinical conditions, laboratory test results, vital signs and medications. A multimodal deep learning (MMDL) model that can handle temporal data using long short-term memory (LSTM) and gated recurrent units (GRUs) was proposed for this prediction task. Four benchmark machine learning models, logistic regression (LR), random forest (RF), gradient boosting decision tree (GBDT) and a published cutting edge MMDL, were used to compare and evaluate the models with a fivefold cross-validation approach. Accuracy, recall, area under the ROC curve (AUC), and average precision (AP) were used to evaluate the discrimination of each model at three time points (24 h, 48 h and 72 h) before CADVT occurred. Brier score and Spiegelhalter’s z test were used measure the calibration of these prediction models.ResultsA total of 1830 patients were included in this study, and approximately 15% developed CADVT. In the CADVT prediction task, the model proposed in this paper significantly outperforms both traditional machine learning models and existing multimodal deep learning models at all 3 time points. It achieved 77% accuracy and 90% recall at 24 h before CADVT was discovered. It can be used to accurately predict the occurrence of CADVT 72 h in advance with an accuracy of greater than 75%, a recall of more than 87%, and an AUC value of 0.82.ConclusionIn this study, a machine learning method was successfully established to predict CADVT in advance. These findings demonstrate that artificial intelligence (AI) could provide measures for thromboprophylaxis in a pediatric intensive care setting.

A Meta-analysis of the Utility of Red Cell Distribution Width as a Biomarker to Predict Outcomes in Pediatric Illness (PROSPERO CRD42020208777)

AbstractRed cell distribution width (RDW) is an average of the variation in red blood cell (RBC) sizes reported on a complete blood count. An elevated RDW indicates a pathological process that is affecting erythropoiesis. Studies showed that as the severity of disease process increases, the RDW often increases as well. Particularly in resource-limited countries, RDW has been studied as an outcome predictor for conditions in a variety of disciplines and is offered as an adjunct monitoring tool that is cost effective, readily available, and indicative of pathological processes amenable to intervention. Particularly in pediatric critical care settings, RDW has been shown to be a reliable tool for surveillance of disease states such as sepsis. Despite the increased attention of RDW as a marker for disease outcome, collective evaluation on the utility of RDW as a marker for outcome in pediatric critical care settings is lacking. We offer a systematic review and meta-analysis of published studies to assess the ability of RDW to predict illness severity and mortality among pediatric critical care patients. Among eight studies of over 4,800 patients, we found over a two-fold increase in odds for mortality in critically ill children whose RDW was above 15.7%. This is the first systematic review of RDW being used to predict mortality in critically ill children and findings of this study may prompt early intervention in the pediatric critical care setting.

Implementing Rapid Whole-Genome Sequencing in Critical Care: A Qualitative Study of Facilitators and Barriers to New Technology Adoption

To characterize the views of members of the multi-disciplinary team regarding the implementation of rapid whole-genome sequencing (rWGS) as a first-tier test for critically ill children in diverse children's hospital settings. Qualitative interviews informed by implementation science theory were conducted with the multidisciplinary patient care teams and hospital leaders at each of the 5 tertiary care children's hospitals involved in a statewide rWGS implementation project. Our analysis revealed 5 key themes regarding the implementation process across the sites: the need for rWGS champions, educational needs and strategies, negotiating decision-making roles and processes, workflows and workarounds, and perceptions about rWGS. From the findings a composite clinical workflow diagram was developed to summarize all of the processes involved in the implementation of the test, and the key areas where implementation practices differed. These findings provide insights for design of interventions to support adoption, scale-up, and sustainability of rWGS and other novel technologies in neonatal and pediatric critical care settings.
