Implementation and outcomes of a quality improvement project to systematically assess the gross motor skills in school-aged children with cystic fibrosis.

INTRODUCTION: Limited data exist on the gross motor abilities of children with cystic fibrosis (CF). The objective of this research project was to implement a systematic gross motor assessment in children with CF ages 4-12 years. Secondarily, we aimed to assess demographic characteristics associated with gross motor delays. METHODS: Physical therapists aimed to evaluate at least 50% of eligible children (4-12 years) at our CF Center over 1 year using the Bruininks-Oseretsky Test of motor Proficiency, second edition (BOT-2). Delays are defined by scores less than 18th percentile. Demographic and clinical data included body mass index, hospitalizations, genotype, and comorbidities. Basic descriptive statistics summarized patient information. Parametric and nonparametric methods compared groups of interest. Linear regression assessed associations between BOT-2 measures and clinical characteristics. RESULTS: The BOT-2 evaluation was successfully implemented with 69% of eligible patients being evaluated. Forty-five (62.5%) scored below average. Impaired strength (22.2%) was most common, followed by impaired balance (16.7%), running speed and agility (15.3%), and bilateral coordination (8.3%). 15.5% scored below average on their total motor composite score (TMC). Increased age, comorbidities and hospitalizations were associated with a lower TMC. CONCLUSIONS: The BOT-2 was successfully implemented as part of routine CF care to screen for gross motor delays in children. Results suggest that a high percentage of children with CF, especially older children with comorbid conditions or a history of hospitalization, have impaired gross motor function. These findings support the need for routine gross motor evaluations and physical therapy interventions within pediatric CF clinics.

Genetic liability for gastrointestinal inflammation disorders and association with gastrointestinal symptoms in children with and without autism.

Children with autism spectrum disorder (ASD) have a greater prevalence of gastrointestinal (GI) symptoms than children without ASD. We tested whether polygenic scores for each of three GI disorders (ulcerative colitis, inflammatory bowel disease, and Crohn's disease) were related to GI symptoms in children with and without ASD. Using genotyping data (564 ASD cases and 715 controls) and external genome-wide association study summary statistics, we computed GI polygenic scores for ulcerative colitis (UC-PGS), inflammatory bowel disease (IDB-PGS), and Crohn's disease (CD-PGS). Multivariable logistic regression models, adjusted for genetic ancestry, were used to estimate associations between each GI-PGS and (1) ASD case-control status, and (2) specific GI symptoms in neurotypical children and separately in ASD children. In children without ASD, polygenic scores for ulcerative colitis were significantly associated with experiencing any GI symptom (adjusted odds ratio (aOR) = 1.36, 95% confidence interval (CI) = 1.03-1.81, p = 0.03) and diarrhea specifically (aOR = 5.35, 95% CI = 1.77-26.20, p = 0.01). Among children without ASD, IBD-PGS, and Crohn's PGS were significantly associated with diarrhea (aOR = 3.55, 95% CI = 1.25-12.34, p = 0.02) and loose stools alternating with constipation (aOR = 2.57, 95% CI = 1.13-6.55, p = 0.03), respectively. However, the three PGS were not associated with GI symptoms in the ASD case group. Furthermore, polygenic scores for ulcerative colitis significantly interacted with ASD status on presentation of any GI symptom within a European ancestry subset (aOR = 0.42, 95% CI = 0.19-0.88, p = 0.02). Genetic risk factors for some GI symptoms differ between children with and without ASD. Furthermore, our finding that increased genetic risks for GI inflammatory disorders are associated with GI symptoms in children without ASD informs future work on the early detection of GI disorders.

Urine Quantification Following Furosemide for Severe Acute Kidney Injury Prediction in Critically Ill Children.

A standardized, quantified assessment of furosemide responsiveness predicts acute kidney injury (AKI) in children after cardiac surgery and AKI progression in critically ill adults. The purpose of this study was to determine if response to furosemide is predictive of severe AKI in critically ill children outside of cardiac surgery. We performed a multicenter retrospective study of critically ill children. Quantification of furosemide response was based on urine flow rate (normalized for weight) measurement 0 to 6 hours after the dose. The primary outcome was presence of creatinine defined severe AKI (Kidney Disease Improving Global Outcomes stage 2 or greater) within 7 days of furosemide administration. Secondary outcomes included mortality, duration of mechanical ventilation and length of stay. A total of 110 patients were analyzed. Severe AKI occurred in 20% ( n = 22). Both 2- and 6-hour urine flow rate were significantly lower in those with severe AKI compared with no AKI ( p = 0.002 and p < 0.001). Cutoffs for 2- and 6-hour urine flow rate for prediction of severe AKI were <4 and <3 mL/kg/hour, respectively. The adjusted odds of developing severe AKI for 2-hour urine flow rate of <4 mL/kg/hour was 4.3 (95% confidence interval [CI]: 1.33-14.15; p = 0.02). The adjusted odds of developing severe AKI for 6-hour urine flow rate of <3 mL/kg/hour was 6.19 (95% CI: 1.85-20.70; p = 0.003). Urine flow rate in response to furosemide is predictive of severe AKI in critically ill children. A prospective assessment of urine flow rate in response to furosemide for predicting subsequent severe AKI is warranted.

Encouraging adherence in adolescents with asthma using financial incentives: An RCT.

BACKGROUND: Medication adherence in adolescents remains a significant management challenge and innovative strategies are needed to improve medication adherence. Financial incentives have been used to improve outcomes for health behaviors among adults, but have not been well-studied among adolescents. The objective of this study was to test if a modest financial incentive improved medication adherence in adolescents with asthma compared with a control group. METHODS: Participants were randomized to either control (electronic medication monitoring [EMM] with App reminders/feedback for 4 months) or intervention (EMM + $1 per day for perfect medication adherence for 3 months [maximum $84] followed by 1 month of EMM only). A repeated measures mixed model, with a first order autoregressive correlation structure between errors, was used to test the null hypothesis for an interaction of treatment group and week. RESULTS: Fifty-two participants were enrolled, and 48 completed primary analysis. Mean adherence rates declined in both groups over time, and there was no significant difference in the change in adherence rates between the groups (F-statistic = 0.72, ndf = 15, ddf = 625, p = 0.76). Adherence rates (during the 12 weeks when incentives were given) declined from 80% to 64% in the control group, and from 90% to 58% in the incentive group. There was no significant change in the slope of decline in the incentives group in the month following payment discontinuation. CONCLUSION: A modest financial incentive did not lead to significantly different medication adherence rates in adolescents with asthma who were receiving a monitoring and reminder intervention. Further study is needed to determine viable interventions to optimize medication use in this group.

A National Survey of U.S. Adolescent Sleep Duration, Timing, and Social Jetlag During the COVID-19 Pandemic.

OBJECTIVES: To assess changes in duration, timing, and social jetlag in adolescent sleep during the COVID-19 pandemic and evaluate the impact of mood, physical activity, and social interactions on sleep. STUDY DESIGN: An online survey queried adolescents' sleep before (through retrospective report) and during the initial phase of COVID-19 in May 2020. Adolescents (N = 3,494), 13-19 years old, in the United States (U.S.) answered questions about their current and retrospective (prior to COVID-19) sleep, chronotype, mood, and physical and social activities. Linear regression models were fit for time in bed, reported bed and wake times, and social jetlag during COVID-19, accounting for pre-COVID-19 values. RESULTS: Total reported time in bed (a proxy for sleep duration) increased on weekdays by an average of 1.3 ± 1.8 hours (p < .001) during COVID-19, compared to retrospective report of time in bed prior to COVID-19. During COVID-19, 81.3% of adolescents reported spending 8 hours or more in bed on weekdays compared to only 53.5% prior to COVID-19. On weekdays, bedtimes were delayed on average by 2.5 hours and wake times by 3.8 hours during COVID-19 compared to prior to COVID-19. On weekends, bedtimes were delayed on average by 1.6 hours and waketimes by 1.5 hours (all p's < 0.001). Social jetlag of >2 hours decreased to 6.3% during COVID-19 compared to 52.1% prior to COVID-19. Anxiety and depression symptoms and a decline in physical activity during COVID-19 were associated with delayed bed and wake times during COVID-19. CONCLUSIONS: During COVID-19, adolescents reported spending more time in bed, with most adolescents reporting 8 hours of sleep opportunity and more consistent sleep schedules. As schools return to in-person learning, additional research should examine how sleep schedules may change due to school start times and what lessons can be learned from changes that occurred during COVID-19 that promote favorable adolescent sleep.

Nasal Tube Securement: Randomized Controlled Trial in Pediatric Hospitalized Patients.

PURPOSE: The aim of this study was to compare accidental dislodgement rates of nasal gastric tubes secured with standard methods or a nasal tube securement device in pediatric patients. DESIGN: A randomized controlled trial was conducted. METHODS: Participants ( n = 43) were randomized into standard securement or nasal tube securement device using block randomization to control for age and diagnosis. Surveys were collected from staff and caregivers on device ease of use and satisfaction. RESULTS: There were a similar number of tube dislodgements for patients in the nasal tube securement device group ( n = 6) and the standard practice group ( n = 7). The median hospital length of stay was higher for the standard practice group (13 days vs. 9 days). CONCLUSION: Use of the nasal tube securement device did not significantly decrease the rate of tube dislodgements compared with standard practice. CLINICAL RELEVANCE TO REHABILITATION NURSING: The study provides information for pediatric rehabilitation nurses in choosing securement options for nasal gastric tubes.

Effect of a standardized fluid management algorithm on acute kidney injury and mortality in pediatric patients on extracorporeal support.

Acute kidney injury (AKI), fluid overload (FO), and mortality are common in pediatric patients supported by extracorporeal membrane oxygenation (ECMO). The aim of this study is to evaluate if using a fluid management algorithm reduced AKI and mortality in children supported by ECMO. We performed a retrospective study of pediatric patients aged birth to 25 years requiring ECMO at a quaternary level children's hospital from 2007 to 2019 In October 2017, a fluid management algorithm was implemented for protocolized fluid removal after deriving a daily fluid goal using a combination of diuretics and ultrafiltration. Daily algorithm compliance was defined as ≥ 12 h on the algorithm each day. The primary and secondary outcomes were AKI and mortality, respectively, and were assessed in the entire cohort and the sub-analysis of children from the era in which the algorithm was implemented. Two hundred and ninety-nine (median age 5.3 months; IQR: 0.2, 62.3; 45% male) children required ECMO (venoarterial in 85%). The fluid algorithm was applied in 74 patients. The overall AKI rate during ECMO was 38% (26% severe-stage 2/3). Both AKI incidence and mortality were significantly lower in patients managed on the algorithm (p = 0.02 and p = 0.05). After adjusting for confounders, utilization of the algorithm was associated with lower odds of AKI (aOR: 0.40, 95%CI: 0.21, 0.76; p = 0.005) but was not associated with a reduction in mortality. In the sub-analysis, algorithm compliance of 80-100% was associated with a 54% reduction in mortality (ref: < 60% compliant; aOR:0.46, 95%CI:0.22-1.00; p = 0.05).  Conclusion: Among the entire cohort, the use of a fluid management algorithm reduced the odds of AKI. Better compliance on the algorithm was associated with lower mortality. Multicenter studies that implement systematic fluid removal may represent an opportunity for improving ECMO-related outcomes. What is Known: • Acute kidney injury and fluid overload are associated with morbidity and mortality in children supported by extracorporeal membrane oxygenation. What is New: • A systematic and protocolized approach to fluid removal in children supported by extracorporeal membrane oxygenation reduces acute kidney injury incidence. • Greater adherence to a protocolized fluid removal algorithm is associated with a reduction in mortality.

Electrolyte derangements in critically ill children receiving balanced versus unbalanced crystalloid fluid resuscitation.

BACKGROUND: Adult studies have demonstrated potential harm from resuscitation with 0.9% sodium chloride (0.9%NaCl), resulting in increased utilization of balanced crystalloids like lactated ringers (LR). The sodium and potassium content of LR has resulted in theoretical safety concerns, although limited data exists in pediatrics. We hypothesized that use of LR for resuscitation would not be associated with increased electrolyte derangements compared to 0.9%NaCl. METHODS: A prospective, observational cohort study of critically ill children who received ≥ 20 ml/kg of fluid resuscitation and were admitted to two pediatric intensive care units from November 2017 to February 2020. Fluid groups included patients who received > 75% of fluids from 0.9%NaCl, > 75% of fluids from LR, and a mixed group. The primary outcome was incidence of electrolyte derangements (sodium, chloride, potassium) and acidosis. RESULTS: Among 559 patients, 297 (53%) received predominantly 0.9%NaCl, 74 (13%) received predominantly LR, and 188 (34%) received a mixture. Extreme hyperkalemia (potassium ≥ 6 mmol/L) was more common in 0.9%NaCl group (5.8%) compared to LR group (0%), p 0.05. Extreme acidosis (pH > 7.1) was more common in 0.9%NaCl group (11%) compared to LR group (1.6%), p 0.016. CONCLUSIONS: LR is associated with fewer electrolyte derangements compared to 0.9%NaCl. Prospective interventional trials are needed to validate these findings.

Nephrotoxic Exposures and Acute Kidney Injury in Noncritically Ill Children Stratified by Service.

OBJECTIVE: The Nephrotoxic Injury Negated by Just-in-Time Action (NINJA) program is a multicenter, quality improvement initiative that identifies patients at risk for nephrotoxic medication-associated acute kidney injury (NTMx-AKI). The purpose of this study was to (1) evaluate the prevalence and types of NTMx exposures and (2) determine the prevalence of NTMx-AKI categorized by service. Exploratory analysis evaluated potential associations between hospital measures and NTMx-AKI. METHODS: This is a single-center, retrospective chart review of NTMx exposures from January 2019 to June 2020 in noncritically ill children. High NTMx exposures were defined as ≥3 simultaneous nephrotoxins or ≥3 days of either intravenous vancomycin or aminoglycoside. Prevalence of high NTMx and NTMx-AKI rate were normalized to 1000 patient days. A retrospective case-control analysis assessed for potential associations with development of NTMx-AKI. RESULTS: There were 609 NTMx exposures in 565 patients and 44 (7.2%) episodes of NTMx-AKI. The NTMx prevalence rate per 1000 patient days was highest among liver, neurosurgery, and gastroenterology services. The most commonly used NTMx were vancomycin, intravenous contrast, and nonsteroidal antiinflammatory drugs. The NTMx-AKI rate in exposed patients ranged from 0% to 14% across service lines. AKI was most often attributable to vancomycin. Univariable analyses suggest type and duration of NTMx exposure are associated with development of NTMx-AKI but not with severity. CONCLUSIONS: NTMx exposures and NTMx-AKI are variable across services. Partnerships with antimicrobial stewardship and multicenter studies are needed to modify NTMx-AKI risk. Ongoing surveillance is needed in patients who do not have normalization of creatinine before discharge.

Decreases in Nephrotoxic Pain Medications Are Not Associated With Increased Opioid Utilization in Critically Ill Children.

OBJECTIVES: Quality improvement initiatives to decrease rates of nephrotoxic medication exposure have reduced rates of acute kidney injury (AKI) in noncritically ill children. The objective of our study was to analyze the implementation of a similar program in critically ill children and to measure important balancing measures including opioid and benzodiazepine exposure. DESIGN: Prospective quality improvement study. SETTING: PICU at Children's Hospital Colorado between 2018 and 2020. PATIENTS: All children admitted to PICU. INTERVENTIONS: Quality improvement initiative called Nephrotoxic Injury Negated by Just-In-Time Action (NINJA). MEASUREMENT AND MAIN RESULTS: Eight thousand eight hundred thirty-three PICU patient admissions were included. Mean rates of nephrotoxic medication exposure/1,000 PICU patient days decreased from 46 to 26, whereas rates of nephrotoxic AKI/1,000 PICU patient days did not change. Nonsteroidal anti-inflammatory drug dispenses per 1,000 patient days were reduced from 521 to 456. Similarly, opioid and benzodiazepine exposures per 1,000 patient days were reduced from 812 to 524 and 441 to 227, respectively, during the study observation period. CONCLUSIONS: The NINJA intervention was efficaciously implemented in our single-center PICU. Nephrotoxic exposure is a modifiable factor that did not inadvertently increase exposure to opioids and benzodiazepines.

A Naturalistic Actigraphic Assessment of Changes in Adolescent Sleep, Light Exposure, and Activity Before and During COVID-19.

The majority of high school-aged adolescents obtain less than the recommended amount of sleep per night, in part because of imposed early school start times. Utilizing a naturalistic design, the present study evaluated changes in objective measurements of sleep, light, and physical activity before (baseline) and during the first wave of the COVID-19 pandemic (during COVID-19) in a group of US adolescents. Sixteen adolescents (aged 15.9 ± 1.2 years, 68.8% female) wore an actigraphy monitor for 7 consecutive days during an in-person week of school before the pandemic (October 2018-February 2020) and again during the pandemic when instruction was performed virtually (May 2020). Delayed weekday sleep onset times of 1.66 ± 1.33 h (p < 0.001) and increased sleep duration of 1 ± 0.87 h (p < 0.001) were observed during COVID-19 compared with baseline. Average lux was significantly higher during COVID-19 compared with baseline (p < 0.001). Weekday physical activity parameters were not altered during COVID-19 compared with baseline, except for a delay in the midpoint of the least active 5 h (p value = 0.044). This analysis provides insight into how introducing flexibility into the traditional school schedule might influence sleep in adolescents.

Acute vaping in a golden Syrian hamster causes inflammatory response transcriptomic changes.

E-cigarette vaping is a major aspect of nicotine consumption, especially for children and young adults. Although it is branded as a safer alternative to cigarette smoking, murine and rat models of subacute and chronic e-cigarette vaping exposure have shown many proinflammatory changes in the respiratory tract. An acute vaping exposure paradigm has not been demonstrated in the golden Syrian hamster, and the hamster is a readily available small animal model that has the unique benefit of becoming infected with and transmitting respiratory viruses, including SARS-CoV-2, without genetic alteration of the animal or virus. Using a 2-day, whole body vaping exposure protocol in male golden Syrian hamsters, we evaluated serum cotinine, bronchoalveolar lavage cells, lung, and nasal histopathology, and gene expression in the nasopharynx and lung through reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Depending on the presence of nonnormality or outliers, statistical analysis was performed by ANOVA or Kruskal-Wallis tests. For tests that were statistically significant (P < 0.05), post hoc Tukey-Kramer and Dunn's tests, respectively, were performed to make pairwise comparisons between groups. In nasal tissue, RT-qPCR analysis revealed nicotine-dependent increases in gene expression associated with type 1 inflammation (CCL-5 and CXCL-10), fibrosis [transforming growth factor-ß (TGF-ß)], nicotine-independent increase oxidative stress response (SOD-2), and a nicotine-independent decrease in vasculogenesis/angiogenesis (VEGF-A). In the lung, nicotine-dependent increases in the expression of genes involved in the renin-angiotensin pathway [angiotensin-converting enzyme (ACE), ACE2], coagulation (tissue factor, Serpine-1), extracellular matrix remodeling (MMP-2, MMP-9), type 1 inflammation (IL-1ß, TNF-α, and CXCL-10), fibrosis (TGF-ß and Serpine-1), oxidative stress response (SOD-2), neutrophil extracellular traps release (ELANE), and vasculogenesis and angiogenesis (VEGF-A) were identified. To our knowledge, this is the first demonstration that the Syrian hamster is a viable model of e-cigarette vaping. In addition, this is the first report that e-cigarette vaping with nicotine can increase tissue factor gene expression in the lung. Our results show that even an acute exposure to e-cigarette vaping causes significant upregulation of mRNAs in the respiratory tract from pathways involving the renin-angiotensin system, coagulation, extracellular matrix remodeling, type 1 inflammation, fibrosis, oxidative stress response, neutrophil extracellular trap release (NETosis), vasculogenesis, and angiogenesis.

Integration of the Codonics Safe Label System® and the Omnicell XT® Anesthesia Workstation into Pediatric Anesthesia Practice: Utilizing Technology to Increase Medication Labeling Compliance and Decrease Medication Discrepancies While Maintaining User Acceptability.

Background: Perioperative medication errors are recognized as a source of patient morbidity and mortality. Medication management systems with built-in scanning and label-printing functions that integrate with medication-dispensing cabinets have the potential to decrease medication administration errors by improving compliance with medication labeling. Whether these management systems will also improve periodic automatic replacement (PAR) inventory control and be accepted by users is unknown. We hypothesized that implementation of the Codonics Safe Label System®, an automated labeling system (ALS), would increase compliance with labeling guidelines and improve PAR inventory control by decreasing medication discrepancies while maintaining user acceptability in the OR. Methods: We audited a cohort of anesthesia workstations and electronic anesthesia records for 2 months to compare dispensed and administered medications and establish a discrepancy baseline. We also observed a convenience sample of syringes to evaluate labeling compliance. Post-implementation of the ALS, we repeated the audit. Finally, an anonymous survey was distributed electronically to providers to assess user acceptability. Results: Pre-implementation the average daily medication discrepancy rate was 9.7%, decreasing to 6.1% post-implementation (χ2 1 = 43.9; P < .0001). Pre-implementation 330 of 696 syringes (47.4%) were either missing a label or labeling elements. After implementation, 100% of all syringes received a label with the complete required labeling information (P < .0001). All respondents agreed or strongly agreed that the system was easy to use, accurate, met their needs, printed labels quickly, improved safety and efficiency, and was recommendable. Conclusion: The ALS significantly increased the rate of best-practice-compliant medication labeling while reducing medication inventory discrepancies. The system was highly accepted by providers.

Applying dissemination and implementation research methods to translate a school-based asthma program.

Our school-based asthma program has reduced asthma exacerbations for youth with health disparities in the Denver metropolitan area, due partly to addressing social determinants of health, such as access to health care and medications. Dissemination and implementation (D&I) science approaches accelerate the translation of evidence-based programs into routine practice. D&I methods are being applied more commonly to improve health equity. The purpose of this publication was to give an overview of D&I research methods, using our school-based asthma program as an example. To successfully scale out our program across the state of Colorado, we are applying a D&I framework that guides the adaptation of our existing implementation approach to better meet our stakeholders' local context-the Exploration, Preparation, Implementation, Sustainment framework. In a pragmatic trial design, we will evaluate the outcomes of implementing the program across 5 Colorado regions, with attention to health equity, using a second commonly used D&I framework-Reach, Effectiveness, Adoption, Implementation, and Maintenance. Our central hypothesis is that our program will have broad and equitable reach to eligible students (primary outcome) and will reduce asthma attacks and symptoms. This D&I approach accelerates dissemination of our program and is an applicable process for translating other effective allergy/asthma programs to address asthma and allergy-related disparities.

High-Altitude Pulmonary Edema in Colorado Children: A Cross-Sectional Survey and Retrospective Review.

Kelly, Timothy D., Maxene Meier, Jason P. Weinman, Dunbar Ivy, John T. Brinton, and Deborah R. Liptzin. High-altitude pulmonary edema in Colorado children: a cross-sectional survey and retrospective review. High Alt Med Biol. 23:119-124, 2022. Introduction: Few studies of high-altitude pulmonary edema (HAPE) are specific to the pediatric population. The purpose of this investigation was to further characterize the radiographic patterns of pediatric HAPE, and to better understand ongoing risk following an initial pediatric HAPE episode. Methods: This study uses both a retrospective chart review and cross-sectional survey. Pediatric patients with HAPE at a single quaternary referral center in the Rocky Mountain Region were identified between the years 2013 and 2020. Patients were eligible if they presented with a clinical diagnosis of HAPE and had a viewable chest radiograph (CXR). Surveys were sent to eligible patients/families to gather additional information relating to family history, puberty, and HAPE recurrence. Results: Forty-two individuals met criteria for clinical diagnosis of HAPE with a viewable CXR. A majority of CXRs (24/42, 57.1%) demonstrated predominant right-sided involvement. Similarly, 24 CXRs (24/42, 57.1%) demonstrated predominant upper lobe involvement. Twenty-one (21/42, 50%) surveys were completed. A minority of individuals went on to experience at least one other HAPE episode (8/19, 42.1%). Conclusion: The most common radiographic pattern seen in pediatric HAPE is pulmonary edema that favors the right lung and upper lobes. After an initial HAPE presentation, some children will experience additional HAPE episodes.

Comprehensive In-Patient Education Consult for Asthma Exacerbations.

BACKGROUND: Asthma is the most common chronic disease leading to hospital admissions and readmissions in childhood. Bedside nurses and respiratory therapists are the primary asthma educators, but they may lack time or knowledge to provide comprehensive asthma education and identify barriers to care. Patients and their parent(s) may benefit from comprehensive education and assessment of barriers from a certified asthma educator. METHODS: A team of certified asthma educators used a quality improvement method to create an in-patient asthma education consulting service. The in-patient pulmonary consult and medical teams referred subjects ≥ 1 y in age with a new or existing diagnosis of asthma who had been admitted to the ICU or identified as having concerns for poor medication adherence to the asthma consult. The asthma consult provided face-to-face education with the subject and parent(s), addressed barriers to the plan of care, and helped facilitate appointments to an asthma specialist after discharge. RESULTS: There were 126 subjects eligible for the asthma consult pilot implemented October 1, 2018-April 30, 2020. The asthma consult saw 52 subjects. Subjects who received consults had a higher rate of previous health care utilization and existing specialist for asthma. After the in-patient stay, the odds of returning to the emergency department/urgent care (UC) or hospital within the following 12 months did not differ between asthma consult and control group. However, after adjusting for covariates of age, race, ethnicity, previous health care utilization, and existing specialist, there was a significant difference in the odds of readmission and revisits (adjusted odds ratio 0.39 [95% CI 0.16-0.98], P = .04) for the asthma consult group compared to the control group. CONCLUSIONS: Providing comprehensive, face-to-face asthma education and working with subjects and their parent(s) to address barriers to medication adherence and facilitate specialty follow-up post discharge decreased health care utilization.

Clinical characteristics of people with cystic fibrosis and frequent fungal infection.

BACKGROUND: Individuals with cystic fibrosis (CF) and fungal airway infection may present with fungal bronchitis, allergic bronchopulmonary aspergillosis (ABPA) or may appear unaffected despite fungal detection. We sought to characterize people with CF with frequent detection of fungi from airway samples and determine clinical outcomes. METHODS: This retrospective study included individuals with CF with ≥4 lower airway cultures over a 2-year baseline period and ≥2 years of follow-up. We defined two groups: ≤1 positive fungus culture (rare) or ≥2 positive cultures during baseline (frequent). Clinical characteristics and outcomes were determined. RESULTS: Between 2004 and 2016, 294 individuals met inclusion with 62% classified as rare and 38% as frequent fungi during baseline. Median follow-up was 6 years (range: 2-9 years). Aspergillus fumigatus was the most common fungal species detected. Individuals with frequent fungi were older (13.7 vs. 11.7 years, p = .02) and more likely to have Stenotrophomonas maltophilia (35% vs. 17%, p < .001) at baseline, but did not differ in lung function or ABPA diagnosis. During follow-up, those with frequent fungi were more likely to have chronic Pseudomonas aeruginosa and S. maltophilia. Individuals with ABPA and frequent fungi had the highest rates of co-infection and co-morbidities, and a trend towards more rapid lung function decline. DISCUSSION: Fungal infection in CF was associated with frequent P. aeruginosa and S. maltophilia co-infection even in those without ABPA. Individuals with frequent fungi and ABPA had worse outcomes, highlighting the potential contribution of fungi to CF pulmonary disease.

Transient and persistent acute kidney injury phenotypes following the Norwood operation: a retrospective study.

BACKGROUND: Acute kidney injury is a common complication following the Norwood operation. Most neonatal studies report acute kidney injury peaking within the first 48 hours after cardiac surgery. The aim of this study was to evaluate if persistent acute kidney injury (>48 postoperative hours) after the Norwood operation was associated with clinically relevant outcomes. METHODS: Two-centre retrospective study among neonates undergoing the Norwood operation. Acute kidney injury was initially identified as developing within the first 48 hours after cardiac surgery and stratified into transient (≤48 hours) and persistent (>48 hours) using the neonatal modification of the Kidney Disease: Improving Global Outcomes serum creatinine criteria. Severe was defined as stage ≥2. Primary and secondary outcomes were mortality and duration of ventilation and hospital length of stay. RESULTS: One hundred sixty-eight patients were included. Transient and persistent acute kidney injuries occurred in 24 and 17%, respectively. Cardiopulmonary bypass and aortic cross clamp duration, and incidence of cardiac arrest were greater among those with persistent kidney injury. Mortality was four times higher (41 versus 12%, p < 0.001) and mechanical ventilation duration 50 hours longer in persistent acute kidney injury patients (158 versus 107 hours; p < 0.001). In multivariable analysis, persistent acute kidney injury was not associated with mortality, duration of ventilation or length of stay. Severe persistent acute kidney injury was associated with a 59% increase in expected ventilation duration (aIRR:1.59, 95% CI:1.16, 2.18; p = 0.004). CONCLUSIONS: Future large studies are needed to determine if risk factors and outcomes change by delineating acute kidney injury into discrete timing phenotypes.

Risk factors for acute kidney injury in neonates with congenital diaphragmatic hernia.

OBJECTIVE: To examine incidence of acute kidney injury (AKI), antenatal and postnatal predictors, and impact of AKI on outcomes in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: Single center retrospective study of 90 CDH infants from 2009-2017. Baseline characteristics, CDH severity, possible AKI predictors, and clinical outcomes were compared between infants with and without AKI. RESULT: In total, 38% of infants developed AKI, 44% stage 1, 29% stage 2, 27% stage 3. Lower antenatal lung volumes and liver herniation were associated with AKI. Extracorporeal life support (ECLS), diuretics, abdominal closure surgery, hypotension, and elevated plasma free hemoglobin were associated with AKI. Overall survival was 79%, 47% with AKI, and 35% with AKI on ECLS. AKI is associated with increased mechanical ventilation duration and length of stay. CONCLUSION: AKI is common among CDH infants and associated with adverse outcomes. Standardized care bundles addressing AKI risk factors may reduce AKI incidence and severity.
