RESUMEN
BACKGROUND: A previous multicenter study showed that longitudinal changes in standard cardiac functional parameters were associated with the development of cardiomyopathy in childhood cancer survivors (CCS). Evaluation of the relationship between global longitudinal strain (GLS) changes and cardiomyopathy risk was limited, largely due to lack of quality apical 2- and 3-chamber views in addition to 4-chamber view. We sought to determine whether apical 4-chamber longitudinal strain (A4LS) alone can serve as a suitable surrogate for GLS in this population. METHODS: A4LS and GLS were measured in echocardiograms with acceptable apical 2-, 3-, and 4-chamber views. Correlation was evaluated using Pearson and Spearman coefficients, and agreement was evaluated with Bland-Altman plots. The ability of A4LS to identify normal and abnormal values compared to GLS as the reference was evaluated. RESULTS: Among a total of 632 reviewed echocardiograms, we identified 130 echocardiograms from 56 patients with adequate views (38% female; mean age at cancer diagnosis 8.3 years; mean follow-up 9.4 years). Correlation coefficients between A4LS and GLS were .89 (Pearson) and .85 (Spearman), with Bland-Altman plot of GLS-A4LS showing a mean difference of -.71 ± 1.8. Compared with GLS as the gold standard, A4LS had a sensitivity of 86% (95% CI 79%-93%) and specificity of 82% (69%-95%) when using normal range cutoffs and 90% (82%-97%) and 70% (58%-81%) when using ±2 standard deviations. CONCLUSION: A4LS performs well when compared with GLS in this population. Given the more recent adoption of apical 2- and 3-chamber views in most pediatric echocardiography laboratories, A4LS is a reasonable stand-alone measurement in retrospective analyses of older study cohorts and echocardiogram biorepositories.

BACKGROUND: Children with aerodigestive dysfunction often undergo triple endoscopy (flexible bronchoscopy, rigid direct laryngoscopy and bronchoscopy, and esophagogastroduodenoscopy) for diagnostic evaluation as well as screening prior to airway reconstruction. Prevalence and risk factors for eosinophilic esophagitis (EoE) in this population are poorly understood. METHODS: A retrospective chart review was performed for pediatric patients, aged 0-21 years, who received a triple endoscopy with biopsy from January 1, 2015, to December 31, 2019, at the Children's Hospital at Montefiore (CHAM). Bivariate and multivariable analyses were used to compare the baseline characteristics between patients with and without EoE to assess for potential predictors of EoE. RESULTS: Of the 119 cases included in the analysis, 16.0 % (19) received a histopathologic diagnosis of EoE following triple endoscopy. Patients with EoE were more likely to have a family history of eczema (p = 0.02) and a dairy-free diet (p = 0.02). Age, sex, history of environmental allergies, and recency of initiating oral diet were not significantly associated with increased odds of an EoE diagnosis. CONCLUSIONS: A family history of eczema and a diet lacking allergenic foods, such as milk, may be associated with an increased risk of a future diagnosis of EoE in patients with aerodigestive dysfunction. Larger, multi-institutional studies are needed to identify early predictors of EoE.

Helicobacter pylori colonizes half of the world's population and is responsible for a significant disease burden by causing gastritis, peptic ulcers, and gastric cancer. The development of host inflammation drives these diseases, but there are still open questions in the field about how H. pylori controls this process. We characterized H. pylori inflammation using an 8-month mouse infection time course and comparison of the wild type (WT) and a previously identified mutant lacking the TlpA chemoreceptor that causes elevated inflammation. Our work shows that H. pylori chronic-stage corpus inflammation undergoes surprising fluctuations, with changes in Th17 and eosinophil numbers. The H. pylori tlpA mutant changed the inflammation temporal characteristics, resulting in different inflammation from the wild type at some time points. tlpA mutants have equivalent total and gland colonization in late-stage infections. During early infection, in contrast, they show elevated gland and total colonization compared to those by WT. Our results suggest the chronic inflammation setting is dynamic and may be influenced by colonization properties of early infection.

In situ simulation has frequently been used to improve team performance and provide an opportunity for the practice of critical skills and identify latent safety threats, which are undetected risks that may lead to adverse outcomes. However, the use of known quality improvement tools to prioritize and mitigate these safety threats is an area requiring further study. Over the course of 9 in situ simulations of a pediatric shock case, postcase debriefs were held to identify latent safety threats in an emergency department and a mixed pediatric and adult inpatient unit. Latent safety threats identified included structure-related threats such as inability to locate critical equipment, knowledge-based threats relating to rapid intravenous fluid administration, and communication-based threats such as lack of role designation. Identification of latent safety threats in the health care environment may assist clinician leaders in mitigating risk of patient harm. The protocol described may be adopted and applied to other critical event simulations, with structured debriefing used as a tool to identify and mitigate threats before they affect the patient.

OBJECTIVE: To investigate perspectives of patients, family members, caregivers (PFC), and healthcare professionals (HCP) on tracheostomy care during the COVID-19 pandemic. METHODS: The cross-sectional survey investigating barriers and facilitators to tracheostomy care was collaboratively developed by patients, family members, nurses, speech-language pathologists, respiratory care practitioners, physicians, and surgeons. The survey was distributed to the Global Tracheostomy Collaborative's learning community, and responses were analyzed. RESULTS: Survey respondents (n = 191) from 17 countries included individuals with a tracheostomy (85 [45 %]), families/caregivers (43 [22 %]), and diverse HCP (63 [33.0 %]). Overall, 94 % of respondents reported concern that patients with tracheostomy were at increased risk of critical illness from SARS-CoV-2 infection and COVID-19; 93 % reported fear or anxiety. With respect to prioritization of care, 38 % of PFC versus 16 % of HCP reported concern that patients with tracheostomies might not be valued or prioritized (p = 0.002). Respondents also differed in fear of contracting COVID-19 (69 % PFC vs. 49 % HCP group, p = 0.009); concern for hospitalization (55.5 % PFC vs. 27 % HCP, p < 0.001); access to medical personnel (34 % PFC vs. 14 % HCP, p = 0.005); and concern about canceled appointments (62 % PFC vs. 41 % HCP, p = 0.01). Respondents from both groups reported severe stress and fatigue, sleep deprivation, lack of breaks, and lack of support (70 % PFC vs. 65 % HCP, p = 0.54). Virtual telecare seldom met perceived needs. CONCLUSION: PFC with a tracheostomy perceived most risks more acutely than HCP in this global sample. Broad stakeholder engagement is necessary to achieve creative, patient-driven solutions to maintain connection, communication, and access for patients with a tracheostomy.

Helicobacter pylori is a chronic bacterial pathogen that thrives in several regions of the stomach, causing inflammation that can vary by site and result in distinct disease outcomes. Whether the regions differ in terms of host-derived metabolites is not known. We thus characterized the regional variation of the metabolomes of mouse gastric corpus and antrum organoids and tissue. The uninfected secreted organoid metabolites differed between the corpus and antrum in only seven metabolites as follows: lactic acid, malic acid, phosphoethanolamine, alanine, uridine, glycerol, and isoleucine. Several of the secreted chemicals were depleted upon H. pylori infection in both regions, including urea, cholesterol, glutamine, fumaric acid, lactic acid, citric acid, malic acid, and multiple nonessential amino acids. These results suggest a model in which H. pylori preferentially uses carboxylic acids and amino acids in complex environments, and these are found in both the corpus and antrum. When organoid metabolites were compared to mouse tissue, there was little overlap. The tissue corpus and antrum metabolomes were distinct, including antrum-elevated 5-methoxytryptamine, lactic acid, and caprylic acid, and corpus-elevated phospholipid products. The corpus and antrum remained distinct over an 8-month infection time course. The antrum displayed no significant changes between the time points in contrast to the corpus, which exhibited metabolite changes that were consistent with stress, tissue damage, and depletion of key nutrients, such as glutamine and fructose-6-phosphate. Overall, our results suggest that the corpus and antrum have largely but not completely overlapping metabolomes that change moderately upon H. pylori infection.

The vacuolar H+ ATPase (V-ATPase) is a complex multisubunit machine that regulates important cellular processes through controlling acidity of intracellular compartments in eukaryotes. Existing small-molecule modulators of V-ATPase either are restricted to targeting one membranous subunit of V-ATPase or have poorly understood mechanisms of action. Small molecules with novel and defined mechanisms of inhibition are thus needed to functionally characterize V-ATPase and to fully evaluate the therapeutic relevance of V-ATPase in human diseases. We have discovered electrophilic quinazolines that covalently modify a soluble catalytic subunit of V-ATPase with high potency and exquisite proteomic selectivity as revealed by fluorescence imaging and chemical proteomic activity-based profiling. The site of covalent modification was mapped to a cysteine residue located in a region of V-ATPase subunit A that is thought to regulate the dissociation of V-ATPase. We further demonstrate that a previously reported V-ATPase inhibitor, 3-bromopyruvate, also targets the same cysteine residue and that our electrophilic quinazolines modulate the function of V-ATPase in cells. With their well-defined mechanism of action and high proteomic specificity, the described quinazolines offer a powerful set of chemical probes to investigate the physiological and pathological roles of V-ATPase.

Type 2 diabetes (DM) is the most common cause of peripheral neuropathy in the Western world. A comorbidity, hypertension, has been speculated to contribute to initiation or worsening of diabetic peripheral neuropathy. We studied adult rat models using genetic strains with DM (Zucker Diabetic Fat rats)±hypertension (HTN (ZSF-1 rats)) to investigate the relative contributions of DM and HTN and the potential for additive effects of HTN upon existing DM for the development of peripheral neuropathy. Long duration sensorimotor behavioral and electrophysiological testing was complemented by histological and molecular methods. Only DM led to tactile and thermal hyperalgesia and affected motor nerve electrophysiology. Although DM led to marked loss of sensory amplitudes and to sensory conduction slowing, a mild additive effect from HTN contributed after 6months of DM with worsening of slowing of sensory nerve conduction velocities, but without effect upon sensory amplitudes. At the sensory dominant sural nerve, mild (<10%) but greater degrees of myelin thinning were noted with DM and HTN combined, suggesting a mild additive effect. Matrix metalloproteinase (MMP) expression was increased only at the sural nerve in the presence of HTN with co-localization to Schwann cells and myelin. The effects of DM and HTN upon peripheral nerve are dissimilar, with HTN contributing to MMP upregulation at the sites of myelin thinning at sensory nerve fibers, potentially worsening comorbid DM. Together, our results indicate that HTN has a mild additive contribution to diabetic peripheral neuropathy at sensory peripheral nerve fibers manifesting with the loss of myelin thickness.

Juvenile ossifying fibroma is a rare, benign tumor that may present in the sinonasal area but has never been described arising from the middle turbinate. The lesion's locally aggressive behavior and close proximity to orbit and anterior skull base create a significant challenge for the patient and practitioner. This is a case presentation of a 7-year-old female with an invasive recurrent juvenile ossifying fibroma arising from the middle turbinate.

BACKGROUND: Tracheostomies are associated with high rates of complications and preventable harm. Safe tracheostomy management requires highly functioning teams and systems, but health care providers are poorly equipped with tracheostomy knowledge and resources. In situ simulation has been used as a quality improvement tool to audit multidisciplinary team emergency response in the actual clinical environment where care is delivered but has been underexplored for tracheostomy care. METHODS: From July 2021 to May 2022, the study team conducted in situ simulations of a tracheostomy emergency scenario at Montefiore Medical Center to identify human errors and latent safety threats (LSTs). Simulations included structured debriefs as well as audiovisual recording that allowed for blind rating of these human errors and LSTs. Provider knowledge deficits were further characterized using pre-simulation quizzes. RESULTS: Twelve human errors and 15 LSTs were identified over 20 simulations with 88 participants overall. LSTs were divided into the following categories: communication, equipment, and infection control. Only 50.0% of teams successfully replaced the tracheostomy tube within the scenario's five-minute time limit. In addition, knowledge gaps were highly prevalent, with a median pre-simulation quiz score of 46% (interquartile range 36-64) among participants. CONCLUSION: An in situ simulation-based quality improvement approach shed light on human errors and LSTs associated with tracheostomy care across multiple settings in one health system. This method of engaging frontline health care provider key stakeholders will inform the development, adaptation, and implementation of interventions.

Objective: Pediatric tracheostomy is associated with high morbidity and mortality, yet clinician knowledge and quality of tracheostomy care may vary widely. In situ simulation is effective at detecting and mitigating related latent safety threats, but evaluation via retrospective video review has disadvantages (eg, delayed analysis, and potential data loss). We evaluated whether a novel mobile application is accurate and reliable for assessment of in situ tracheostomy emergency simulations. Methods: A novel mobile application was developed for assessment of tracheostomy emergency in situ simulation team performance. After 1.25 hours of training, 6 raters scored 10 tracheostomy emergency simulation videos for the occurrence and timing of 12 critical steps. To assess accuracy, rater scores were compared to a reference standard to determine agreement for occurrence or absence of critical steps and a timestamp within ±5 seconds. Interrater reliability was determined through Cohen's and Fleiss' kappa and intraclass correlation coefficient. Results: Raters had 86.0% agreement with the reference standard when considering step occurrence and timing, and 92.8% agreement when considering only occurrence. The average timestamp difference from the reference standard was 1.3 ± 18.5 seconds. Overall interrater reliability was almost perfect for both step occurrence (Fleiss' kappa of 0.81) and timing of step (intraclass correlation coefficient of 0.99). Discussion: Using our novel mobile application, raters with minimal training accurately and reliably assessed videos of tracheostomy emergency simulations and identified areas for future refinement. Implications for Practice: With refinements, this innovative mobile application is an effective tool for real-time data capture of time-critical steps in in situ tracheostomy emergency simulations.
RESUMEN
Importance: Categorization systems for adverse events are not standardized across care settings and specialties and do not always include near miss events (events where there was potential for patient harm, but where no actual harm occurred), making it difficult to effectively assess patient safety for quality improvement. Objective: To develop and assess interrater agreement on a classification system for adverse events reporting that incorporates events in both inpatient and outpatient settings across medical and surgical subspecialties including near miss events. Design, Setting, and Participants: A cross-sectional study in a tertiary care center including 174 patient cases occurring from 2018 to 2020 was carried out. Data were abstracted from a Department of Otorhinolaryngology-Head and Neck Surgery Quality Assurance database. The cases were comprised of near miss and adverse events occurring in adult and pediatric patients in inpatient, outpatient, and emergency department settings. The ratings took place in March and April of 2022. Exposures: Four raters (2 attending physicians and 2 senior resident physicians) were recruited to classify these cases according to 3 classification systems: the National Coordinating Council for Medication Error Reporting and Prevention (NCC-MERP), Clavien-Dindo, and our novel Quality Improvement Classification System (QICS). Main Outcomes and Measures: The primary outcome was overall interrater agreements using Fleiss κ. Results: Across all 4 raters grading 174 cases, the NCC-MERP, Clavien-Dindo, and QICS received a κ score. Fair-to-moderate interrater reliability was observed between the resident and attending physician groups across the 3 classification systems: NCC-MERP (κ = 0.33; 95% CI, 0.30-0.35), Clavien-Dindo (κ = 0.47; 95% CI, 0.43-0.50), and QICS (κ = 0.42; 95% CI, 0.39-0.44). Strong interrater concordance was observed for complications across all scenarios. Conclusion and Relevance: This cross-sectional study found that the new QICS classification scheme was applicable to wide-ranging clinical scenarios with a focus on patient-centered outcomes including near miss events. In addition, QICS allowed for the comparison of patient outcome data in a multitude of settings.

OBJECTIVE: To characterize the efficacy of human papillomavirus (HPV) vaccination as an adjuvant therapy in recurrent respiratory papillomatosis (RRP). DATA SOURCES: PubMed, Embase, Cochrane, Google Scholar, ClinicalTrials.gov, and Web of Science databases were queried for articles published before April 2021. REVIEW METHODS: All retrieved studies (n = 870) were independently analyzed by two reviewers according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement using predefined inclusion and exclusion criteria. 13 studies met inclusion criteria. A random-effects meta-analysis was performed to study intersurgical interval (ISI) and number of surgical procedures per year before and after vaccination. RESULTS: The systematic review included 13 studies, comprising 243 patients. All studies utilized the Gardasil® quadrivalent vaccine, and one study (Yiu et al. 2019) utilized both the quadrivalent and Gardasil® 9-valent vaccines. Our meta-analysis included 62 patients with ISI data across 4 studies, and 111 patients with data on the number of surgical procedures per month across 7 studies. The mean number of surgical procedures decreased by 4.43 per year after vaccination (95% CI, -7.48 to -1.37). Mean ISI increased after vaccination, with a mean difference of 15.73 months (95% CI, 1.46-29.99). Two studies reported on HPV sero-conversion, with HPV seropositivity of 100% prior to vaccination and 25.93% after vaccination. CONCLUSION: The addition of HPV vaccination was associated with an increase in time between surgeries and reduction in the number of surgical procedures required. HPV vaccination may be a beneficial adjuvant treatment for RRP. LEVEL OF EVIDENCE: NA Laryngoscope, 133:2046-2054, 2023.

BACKGROUND: In situ simulation has emerged as a powerful tool for identifying latent safety threats (LSTs). After the first wave of the SARS-CoV-2 pandemic, an urban community emergency department (ED) identified opportunities for improvement surrounding acute airway management and particularly focused on infection control precautions, equipment availability, and interprofessional communication during acute resuscitation. Using the Model for Improvement, a hybrid in situ/quality improvement initiative was implemented using Plan-Do-Study-Act (PDSA) cycles to enhance systems for intubating patients with SARS-CoV-2. METHODS: Three PDSA cycles consisting of 10 simulations each were conducted from June 2020 through February 2021. Latent safety threats (LST) were identified through an in situ simulation scenario involving a patient with SARS-CoV-2 in acute respiratory failure. LSTs were collected through structured debriefs focused on (1) infection control, (2) equipment availability, and (3) communication. The SAFER-Matrix was used to score LSTs according to frequency and likelihood of harm by members of the ED QI team (SAFER score). The research team worked with the same QI leaders to implement action plans based on scored threats using cause-and-effect and driver diagrams. The Donabedian model was used to conceptually evaluate the quality of interventions upon conclusion of the third PDSA cycle. RESULTS: The median SAFER score decreased from 10.94 in PDSA cycle 1 to 6.77 in PDSA cycle 2 to 4.71 in PDSA cycle 3. Across all identified LSTs, the SAFER score decreased by 3.114 for every additional PDSA cycle ( P = 0.0167). When evaluating for threats identified as being primarily structure based, there was a decrease in SAFER score of 1.28 per every additional PDSA cycle ( P = 0.001). There was a decrease in total count of LST of 0.20 per additional simulation run ( P = 0.02) after controlling for shift type, census, perceived workload, team size, and prior attendance in simulations across all PDSA cycles. CONCLUSIONS: This study presents a blueprint for the utilization of in situ simulation through multiple waves of the SARS-CoV-2 pandemic to identify LSTs and use the SAFER score as a surrogate marker to monitor the impact of interventions for a safer environment for both medical staff and patients.

BACKGROUND Vernix caseosa peritonitis (VCP) is a rare complication that typically presents following an otherwise uneventful cesarean section. Leakage of vernix caseosa into the peritoneum is thought to elicit a granulomatous foreign body reaction. Symptoms can be similar to other acute abdominal conditions, and diagnosis is confirmed by intraoperative findings and histological examination. Peritoneal lavage with supportive measures is the mainstay of treatment and recovery. CASE REPORT Case 1 was a 30-year-old woman who developed right iliac fossa pain, fever, tachycardia, and tachypnea less than a week after her lower segment cesarean section (LSCS). She underwent a laparoscopy for a peritonitic abdomen and concern for intra-abdominal sepsis. A peritoneal biopsy demonstrated histological changes consistent with VCP. Case 2 was a 39-year-old woman who underwent a LSCS. After discharge, she re-presented with generalized abdominal pain. With computed tomography (CT) scan findings suggestive of appendicitis, an appendectomy was performed, and vernix caseosa was detected in all quadrants. Case 3 was a 33-year-old woman who presented with fever, vomiting, diarrhea, and iliac fossa pain 9 days following an LSCS. She was given analgesia and antibiotics for a pelvic fluid collection noted on CT scan. She re-presented with tense swelling and pain above her cesarean section incision. Laparoscopy revealed adhesions over the lower abdomen and pelvis and white plaques suggestive of vernix caseosa along the peritoneal side walls. CONCLUSIONS The rising incidence of cesarean births worldwide creates the potential for increased numbers of VCP cases. Greater recognition of VCP is warranted to prevent unnecessary procedures.

STUDY OBJECTIVE: Assess the prevalence of and risk factors for pediatric pulmonary hypertension (PH) in the 2016 Kids' Inpatient Database (KID), including obstructive sleep apnea (OSA) and obesity. METHODS: Retrospective cross-sectional cohort study utilizing 6,081,132 weighted pediatric discharges from the 2016 KID. Study variables included age, length of stay, mortality, gender, hospital region, primary payer, race, median household income for patient's ZIP code, OSA, central sleep apnea (CSA), obesity, Down syndrome, sickle cell disease (SCD), thalassemia, congenital heart disease (CHD), hypertension, asthma and chronic lung disease of prematurity (CLDP). PH was the primary outcome of interest. Bivariate and multivariable logistic regression models were utilized with odds ratios and 95 % confidence intervals. RESULTS: The mean age was 3.76 years, the mean hospital length of stay was 3.85 days, 48.9 % were male, 52.6 % had government health insurance, 51.0 % were White, 16.1 % were Black, 21.1 % were Hispanic, 5.0 % were Asian or Pacific Islander, 0.80 % were Native American and 6.1 % identified as "other". The prevalence of PH was 0.21 % (12,777 patients). There were 37,631 patients with OSA and the prevalence of PH among this cohort was 3.3 %, over 10x greater than the overall prevalence of PH in the 2016 KID (0.21 %). Risk factors associated with PH included CLDP, CHD, Down syndrome, asthma, OSA, CSA, hypertension, SCD, obesity, race/ethnicity, government insurance, age, male gender (p < 0.0001), and hospital region (p = 0.0002). CONCLUSIONS: Several risk factors were independently associated with PH, such as OSA, CSA, obesity, asthma, and insurance status. Prospective multi-institutional studies are needed to assess the relationships between these risk factors, severity metrics, and causative links in the development of PH; in addition to identifying children with OSA who are most likely to benefit from cardiopulmonary screening prior to adenotonsillectomy. LEVEL OF EVIDENCE: Level III.

Objective: Tracheostomy tube change is a multistep skill that must be performed rapidly and precisely. Despite the critical importance of this skill, there is wide variation in teaching protocols. Methods: An innovative operant conditioning teaching methodology was employed and compared to traditional educational techniques. Medical student volunteers at a tertiary care academic institution (Albert Einstein College of Medicine) were recruited and randomly distributed into 2 groups: operant vs traditional (control). Following the educational session, each group was provided with practice time and then asked to perform 10 tracheostomy tube changes. Performance was recorded and scored by blinded raters using deidentified video recordings. Results: The operant learning group (OLG) demonstrated greater accuracy in performing a tracheostomy tube change than the traditional demonstration group. Twelve of 13 operant learners performed the skill accurately each time compared to 3 of 13 in the traditional group (P = 0.002). The median lesson time was longer for the OLG (535 seconds) than for the traditional group, (200 seconds P < 0.001). The average time per tracheostomy change was not significantly different between the 2 groups (operant learners mean 7.1 seconds, traditional learners mean 7.5 seconds, P = 0.427). Discussion: Although the operant conditioning methodology necessarily requires a greater time to teach, the results support this methodology over traditional learning modalities as it enhances accuracy in the acquired skill. Operant learning methodology is under consideration for other skills and education sessions in our program. Future steps include the application and adaptation of this education model to students and residents in other settings and fields. Implications for Practice: Operant learning is effective for teaching multistep skills such as tracheostomy tube changes with decreased error rates.
RESUMEN
OBJECTIVE: To achieve consensus on critical steps and create an assessment tool for actual and simulated pediatric tracheostomy emergencies that incorporates human and systems factors along with tracheostomy-specific steps. METHODS: A modified Delphi method was used. Using REDCap software, an instrument comprising 29 potential items was circulated to 171 tracheostomy and simulation experts. Consensus criteria were determined a priori with a goal of consolidating and ordering 15 to 25 final items. In the first round, items were rated as "keep" or "remove". In the second and third rounds, experts were asked to rate the importance of each item on a 9-point Likert scale. Items were refined in subsequent iterations based on analysis of results and respondents' comments. RESULTS: The response rates were 125/171 (73.1%) for the first round, 111/125 (88.8%) for the second round, and 109/125 (87.2%) for the third round. 133 comments were incorporated. Consensus (>60% participants scoring ≥8, or mean score >7.5) was reached on 22 items distributed across three domains. There were 12, 4, and 6 items in the domains of tracheostomy-specific steps, team and personnel factors, and equipment respectively. CONCLUSIONS: The resultant assessment tool can be used to assess both tracheostomy-specific steps as well as systems factors affecting hospital team response to simulated and clinical pediatric tracheostomy emergencies. The tool can also be used to guide debriefing discussions of both simulated and clinical emergencies, and to spur quality improvement initiatives.

BACKGROUND: In situ simulation has emerged as a powerful quality improvement (QI) tool in the identification of latent safety threats (LSTs). Following the first wave of SARS-CoV-2 at an urban epicenter of the disease, a multi-institutional collaborative was formed to integrate an in situ simulation protocol across five emergency departments (EDs) for systems improvement of acute airway management. METHODS: A prospective, multi-institutional QI initiative using two Plan-Do-Study-Act (PDSA) cycles was implemented across five EDs. Each institution conducted simulations involving mannequins in acute respiratory failure requiring definitive airways. Simulations and systems-based debriefs were standardized. LSTs were collected in an online database, focused on (1) equipment availability, (2) infection control, and (3) communication. RESULTS: From June 2020 through May 2021, 58 of 70 (82.9%) planned simulations were completed across five sites with 328 unique individual participants. Overall LSTs per simulation (7.00-4.69, p < 0.001) and equipment LSTs (3.00-1.46, p < 0.001) decreased from cycle 1 to cycle 2. Changes in mean LSTs for infection control and communication categories varied among sites. There was no correlation between total LSTs or any of the categories and team size. Number of beds occupied was significantly negatively correlated with total and infection control LSTs. CONCLUSION: This study was unique in simultaneously running a structured in situ protocol across numerous diverse institutions during a global pandemic. This initiative found similar categories of threats across sites, and the protocol developed empowered participants to implement changes to mitigate identified threats.
