Identifying asthma-related risks during hospitalization using the child asthma risk assessment tool.

Objective: The Child Asthma Risk Assessment Tool (CARAT) identifies risk factors for asthma morbidity. We hypothesized that CARAT-identified risk factors (using a CARAT adapted for inpatient use) would be associated with future healthcare utilization and would identify areas for intervention.Methods: We reviewed CARAT data collected during pediatric asthma admissions from 2010-2015, assessing for risk factors in environmental, medical, and social domains and providing prompts for inpatient (specialist consultation or social services engagement) and post-discharge interventions (home care visit or home environmental assessment). Confirmatory factor analysis identified groups of CARAT-identified risk factors with similar effects on healthcare utilization (latent factors). Structural equation models then evaluated relationships between latent factors and future utilization.Results: There were 2731 unique patients admitted for asthma exacerbations; 1015 (37%) had complete CARAT assessments and were included in analyses. Those with incomplete CARAT assessments were more often younger and privately-insured. CARAT-identified risk factors across domains were common in children hospitalized for exacerbations. Risks in the environmental domain were most common. Inpatient asthma consults by pulmonologists or allergists and home care referrals were the most frequent interventions indicated (62%, 628/1015, and 50%, 510/1015, respectively). Two latent factors were positively associated with healthcare utilization in the year after index stay - social stressors and known/suspected allergies (both p < 0.05). Stratified analyses analyzing data just from those children with prior healthcare utilization also indicated known/suspected allergies to be positively associated with future utilization.Conclusions: Inpatient interventions to address social stressors and allergic profiles may be warranted to reduce subsequent asthma morbidity.

Personalized Research on Diet in Ulcerative Colitis and Crohn's Disease: A Series of N-of-1 Diet Trials.

INTRODUCTION: Evidence about specific carbohydrate diet (SCD) for inflammatory bowel disease (IBD) is limited. We conducted 54 single-subject, double-crossover N-of-1 trials comparing SCD with a modified SCD (MSCD) and comparing each with the participant's baseline, usual diet (UD). METHODS: Across 19 sites, we recruited patients aged 7-18 years with IBD and active inflammation. Following a 2-week baseline (UD), patients were randomized to 1 of 2 sequences of 4 alternating 8-week SCD and MSCD periods. Outcomes included fecal calprotectin and patient-reported symptoms. We report posterior probabilities from Bayesian models comparing diets. RESULTS: Twenty-one (39%) participants completed the trial, 9 (17%) completed a single crossover, and 24 (44%) withdrew. Withdrawal or early completion occurred commonly (lack of response [n = 11], adverse events [n = 11], and not desiring to continue [n = 6]). SCD and MSCD performed similarly for most individuals. On average, there was <1% probability of a clinically meaningful difference in IBD symptoms between SCD and MSCD. The average treatment difference was -0.3 (95% credible interval -1.2, 0.75). There was no significant difference in the ratio of fecal calprotectin geometric means comparing SCD and MSCD (0.77, 95% credible interval 0.51, 1.10). Some individuals had improvement in symptoms and fecal calprotectin compared with their UD, whereas others did not. DISCUSSION: SCD and MSCD did not consistently improve symptoms or inflammation, although some individuals may have benefited. However, there are inherent difficulties in examining dietary changes that complicate study design and ultimately conclusions regarding effectiveness.

Early Atherosclerotic Inflammatory Pathways in Children with Obstructive Sleep Apnea.

OBJECTIVE: To evaluate structural and functional carotid changes and inflammatory profiles in children with obstructive sleep apnea (OSA) and healthy controls. STUDY DESIGN: Patients with OSA and matched controls (ages 5-13 years) were recruited. Proinflammatory cytokines and acute phase reactants were measured at 6:00 p.m. Common carotid artery measures were determined using ultrasound. Confirmatory factor analysis was used to determine subgroups of cytokines and their effects on carotid measures. RESULTS: Ninety-six patients participated (53 healthy controls, 43 patients with OSA). OSA was associated with increased proinflammatory cytokines (cluster of differentiation-40 ligand [CD40-L], interleukin [IL]-6, and IL-8) and high sensitivity C-reactive protein (P < .05 for all). One cytokine subgroup (IL-6 and IL-8) was negatively associated with markers of carotid function, indicating reduced arterial distensibility and increased stiffness (P < .05 for 3 ultrasound measures); and tumor necrosis factor-α had an opposing effect on carotid function compared with this cytokine subgroup (P < .05 for 2 ultrasound measures). Linear regression demonstrated significant associations between and tumor necrosis factor- α and 2 measures of carotid function (P < .05 for each). Children with OSA did not have functional or structural carotid changes compared with controls. CONCLUSION: OSA was not directly associated with structural and functional carotid changes but was associated with upregulation of key proinflammatory cytokines (sCD40-L, IL-6, and IL-8). Together, IL-6 and IL-8 were associated with changes in carotid function. Longitudinal studies are needed to demonstrate that the inflammatory milieu observed in our population is a precursor of atherosclerosis in children.

Use of the composite asthma severity index in a pediatric subspecialty clinic.

BACKGROUND: The Composite Asthma Severity Index (CASI) is a comprehensive tool to assess asthma severity, which has been applied in the research setting. OBJECTIVE: To evaluate, in an outpatient setting, whether a CASI score accurately predicts asthma severity or control as determined by means of subspecialist assessment. Asthma Control Test (ACT) and childhood ACT (C-ACT) scores were generated to provide additional context for CASI scores in relationship to assessments using another clinical tool. METHODS: Children aged 5 to 18 years with a physician diagnosis of persistent asthma were recruited from a tertiary care center. A pediatric pulmonologist made determinations on each participant's asthma severity and control during a clinic visit. A CASI and ACT/C-ACT score was generated for each patient. Logistic regression and Spearman correlations were used to determine how well CASI scores predicted physician assessments. Agreement between ACT/C-ACT scores and physician assessment of asthma control was determined in supplemental analyses. RESULTS: CASI scores strongly predicted physician assessment of severity (Spearman correlation = 0.61, P < .001); unadjusted odds ratio (OR) equal to 36.67 (95% confidence interval [CI]: 8.83-152.34); and adjusted OR equal to 32.76 (95% CI: 85.70-188.44). In supplemental analyses, ACT/C-ACT scores strongly predicted physician assessment of control (Spearman correlation = 0.72, P < .001) with an unadjusted OR equal to 42.12 (95% CI: 13.34-133.00) and adjusted OR equal to 55.34 (95% CI: 13.62-224.89). CONCLUSION: Use of the CASI was feasible and accurately predicted physician assessments of asthma severity and control in this sample, which are not distinct entities. The CASI is a robust tool that may be used successfully in ambulatory pediatric asthma care.

Weighing in on asthma: Insights on BMI, magnesium, and hospitalizations from the Ohio Pediatric Asthma Repository.

Objective: Little is known about weight status and its effects on clinical course during hospitalization for asthma exacerbation. We sought to evaluate associations between weight status, specifically body mass index (BMI), with inpatient clinical course and clinical history.Methods: We retrospectively analyzed data from 2012 to 2013 on children hospitalized for asthma exacerbation in a state-wide longitudinal cohort, the Ohio Pediatric Asthma Repository. We examined BMI continuously (z scores) and categorically, comparing overweight and obese (Ov/Ob) to non-overweight and non-obese (nOv/nOb) children. We used linear mixed models controlling for site effects to determine if BMI was related to length of stay, as determined by physiologic readiness for discharge (PRD), defined as time to albuterol spaced every 4 h, need for nonstandard care or clinical history.Results: Across six hospitals, 874 children were included in analyses. BMI was positively associated with PRD (p=.008) but this increase was unlikely to be clinically significant. Ov/Ob children were more likely than nOv/nOb to require nonstandard care with repeat magnesium dosing in intensive care after dosing in the emergency department (OR = 3.23, 95%CI 1.39-7.78). Hospitalization in the year prior to enrollment was positively associated with BMI percentile (73.3 vs. 66.0, p=.028). Sleep disordered breathing was also associated with higher BMI percentile (78.2 vs. 65.9; p=.0013).Conclusions: Ov/Ob children had similar PRD to nOv/nOb children and were prone to repeat magnesium dosing. Previous hospitalization for exacerbation was positively associated with increasing BMI percentile. Additional research should investigate differential magnesium use by weight status, quantifying risks and benefits.

Parents' decisions about HPV vaccine for sons: the importance of protecting sons' future female partners.

Parents' decisions about human papillomavirus (HPV) vaccine for sons may be influenced by potentially protecting sons' future female partners from HPV. We sought to identify characteristics of parents likely to consider future partner protection in vaccine decisions, and to determine if parents likely to consider future partners in vaccine decisions had greater intention to vaccinate. We performed a cross-sectional survey of parents with sons in a pediatric clinic in 2010. We used Fisher's exact tests to identify demographics associated with consideration of future female partners in vaccine decisions. We used adjusted logistic regression to determine if parents likely to consider future partner protection in vaccine decisions had greater intention to vaccinate sons. Most parents (76 %, 187/246) reported vaccine decisions for sons were likely to be influenced by preventing HPV transmission from sons to their female partners. Parents 40 years and older, White and Black parents (vs other race), non-Hispanic, and college-educated parents were significantly more likely to indicate female partner protection may influence vaccine decisions (p < 0.05). Parents likely to be influenced by female partner protection in vaccine decisions had greater intention to vaccinate sons than their counterparts (adjusted odds ratio 2.54, 95 % CI 1.22, 5.28). Overall, many parents were likely to consider sons' female partners in vaccine decisions. Because parents likely to consider female partners had increased intention to vaccinate sons, future efforts to improve vaccine uptake in boys should explore the benefits of highlighting potential female partner protection, as this concept may resonate with many parents.

Comparison of high flow nasal cannula therapy to nasal oxygen as a treatment for obstructive sleep apnea in infants.

INTRODUCTION: Obstructive sleep apnea (OSA) in infants is treated with low flow oxygen via nasal cannula (NC), CPAP (continous positive airway pressure), or surgery. Literature supports the use of high flow NC (HFNC) in children in the outpatient setting, however there is limited data on the use of HFNC in infants. OBJECTIVE: The purpose of this study was to compare HFNC and low-flow oxygen as treatments for OSA in infants. METHODS: A prospective pilot study was performed at two institutions. Infants with primarily OSA underwent a 3-4 h sleep study with HFNC titration at 6-14 lpm for OSA, followed by clinical polysomnography (PSG) for oxygen titration (1/8-1 lpm). Infants with primarily central apnea were excluded. RESULTS: Nine infants were enrolled, with a mean age of 1.3 ± 1.7 months. Average apnea hypopnea index (AHI), average obstructive apnea hypopnea index (OAHI) and average central apnea index during the diagnostic PSG was 17.2 ± 7/h, 13.4 ± 5.4/h and 3.7 ± 4.8/h respectively. OSA improved in 44.4% of subjects with HFNC; the mean AHI and OAHI decreased from 15.6 ± 5.65/h and 12.8 ± 4.4/h on diagnostic PSG to 5.12 ± 2.5/h and 4.25 ± 2.5/h on titration PSG. OSA improved universally with low flow oxygen; the mean AHI decreased from 17.2 ± 7/h on diagnostic PSG to 4.44 ± 3.6/h on titration PSG. CONCLUSION: HFNC reduced OSA in some infants, though low flow oxygen reduced OSA in all subjects. Respiratory instability (high loop gain) in infants may explain why infants responded to low flow oxygen. More studies are needed to determine if HFNC is beneficial in selected groups of infants with OSA.

Home Insulin Pump Use in Hospitalized Children With Type 1 Diabetes.

Importance: Pediatric data on inpatient home insulin pumps are absent in the literature. Understanding safety of home insulin pumps, managed by patients or caregivers, during times of illness will help diabetes technology securely move into pediatric hospitals. Objective: To examine whether insulin can be safely and accurately delivered to hospitalized children through home insulin pumps when managed by patients or caregivers. Design, Setting, and Participants: This single-center, retrospective, observational cohort study included children with insulin-dependent diabetes admitted to a tertiary children's hospital from January 1, 2016, to December 31, 2021. In all these patients, diabetes was the primary or secondary diagnosis on admission. Exposure: Insulin delivery via home insulin pump, hospital insulin pump, or subcutaneous injection. Main Outcomes and Measures: Hyperglycemia (glucose, >250 mg/dL) and hypoglycemia (glucose, <45 mg/dL) rates (quantified as the proportion of total insulin-days), glucose variability, and diabetic ketoacidosis (DKA) recurrences were compared for hospital pumps (manual mode), home pumps (manual mode), and subcutaneous injections using bivariate tests. Results: There were 18 096 insulin-days among 2738 patients aged 0.5 to 25 years (median age, 15.8 years [IQR, 12.3-18.3 years]). Overall, 990 (5.5%) of insulin-days involved hospital insulin pumps, and 775 (4.3%) involved home pumps. A total of 155 insulin-days (15.7%) involving hospital pumps were hyperglycemic, compared with 209 (27.0%) involving home pumps and 7374 (45.2%) involving injections (P < .001). Moderate hypoglycemia days comprised 31 insulin-days (3.1%) involving hospital pumps compared with 35 (4.5%) involving home pumps and 830 (5.1%) involving injections (P = .02). Severe hypoglycemia did not differ significantly according to insulin delivery method. Two patients using injections (0.01%) developed DKA; no patients using hospital or home pumps developed DKA. Conclusions and Relevance: In this cohort study, home insulin pump use was found to be safe in a children's hospital regarding hyperglycemia and hypoglycemia. These data support use of home insulin pumps during pediatric admissions in patients who do not require intensive care and without active DKA.

Education-related needs for children with cystic fibrosis: Perspectives of US pediatric care teams.

OBJECTIVE: Patients with cystic fibrosis (CF) often bring education-related concerns to their medical teams. Concerns around the ability for CF care teams to identify and address these concerns exist. We sought to describe CF care team perceptions of (1) patient and family education-related needs, (2) how these needs are identified, documented and addressed, and (3) education-related resource gaps. METHODS: A survey was emailed to pediatric care teams in the CF Foundation Care Center Network in April 2022. Individuals or care teams could complete the survey. Responses were aggregated for descriptive analysis. RESULTS: Sixty-seven programs responded representing 52% of United States pediatric CF centers. Most centers (88%) indicated social workers primarily address school concerns. Care teams often complete school forms (99%), coach families to communicate with schools (96%), communicate with schools directly (90%), and develop educational plans (76%). Formal education risk assessment and support programs are relatively uncommon (19%). Common student-specific needs include carrying medications (75%) and leaving class for gastrointestinal issues (54%). Needs reported are informational materials for families and schools (94%), staff education about school concerns and how to address them (91%), additional staff for education-related issues (65%), and expertise in education plan development (62%). CONCLUSION: CF care teams often lack comprehensive resources to identify and address education-related concerns. Systematically performing needs assessments, improving training for providers, and evaluating the benefits of education specialists on care teams may better identify and address education-related needs. Supporting educational progression will foster continued independence and well-being in adulthood.

Circadian blood pressure dysregulation in children with obstructive sleep apnea.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) adversely affects normal blood pressure (BP) and may disrupt circadian BP patterns. We sought to examine 24-hour circadian BP rhythms in children with OSA and healthy controls. METHODS: Children 5-14 years with OSA and healthy controls underwent 24-hour BP monitoring and actigraphy to quantify sleep. Shape invariant statistical models compared circadian BP patterns (e.g. times of BP peaks, time arrived at peak BP velocity [TAPV]) in the OSA and control groups. RESULTS: The analytic sample included 219 children (mild OSA: n = 52; moderate-to-severe OSA (MS-OSA): n = 50; controls: n = 117). In the morning, the MS-OSA group had earlier TAPV for DBP than controls (51 minutes, p < 0.001). TAPV in the evening was earlier for the MS-OSA group than controls (SBP: 95 minutes, p < 0.001; DBP: 28 minutes, p = 0.028). At mid-day, SBP and DBP velocity nadirs were earlier for the MS-OSA group than controls (SBP: 57 minutes, p < 0.001; DBP: 38 minutes, p < 0.01). The MS-OSA group reached most BP values significantly earlier than controls; the largest differences were 118 minutes (SBP) and 43 minutes (DBP) (p < 0.001). SBP and DBP were elevated in the MS-OSA group (hours 18-21 and 7--12, respectively, p < 0.01) compared to controls. The MS-OSA group was prone to "non-dipping" compared to controls (SBP: odds ratio [OR] = 2.16, 95% CI: 1.09, 4.29; DBP: OR = 3.45, 95% CI: 1.21, 10.23). CONCLUSIONS: Children with MS-OSA had changes in circadian BP patterns, namely earlier TAPV and BP peaks and nadirs than controls. Circadian disturbances in BP rhythms may be key to mapping the natural history of BP dysregulation in children with OSA.

Integrating education for clinical practice change.

BACKGROUND: Children with chronic medical conditions and their families have significant emotional health concerns, yet paediatricians are often ill-equipped to address these needs. The American Board of Pediatrics launched the Roadmap Project to better support emotional health as part of routine care. We present pilot work in paediatric training programmes to test educational approaches and explore lessons learned. APPROACH: Four institutions implemented Roadmap tools into their paediatric training programmes, either incorporating them into existing educational structures or embedding them into the clinical workplace. One programme utilised an existing longitudinal curriculum, and another incorporated into a block rotation. Two programmes embedded training for residents into a larger programme for the healthcare team within the clinical space, one in outpatient clinics and one in an inpatient service. EVALUATION: Evaluation strategies at each site matched the intended outcomes. Sites working within education programmes evaluated learners, demonstrating increases in resident skills and confidence on pre-/post-self-assessments. Sites embedding tools into the practice context measured changes in the clinical practice of the healthcare team. Despite variability in implementation, all approaches improved trainee skills; sites embedding education into a clinical setting saw greater changes in clinical practice. IMPLICATIONS: Our pilot provided structure yet allowed for flexibility, and all sites improved trainee skills. Engaging the entire healthcare team within practice settings appears advantageous, thus embedding education into clinical practice may be preferable to a separate education programme. Similar to outcomes found in interprofessional education (IPE), educating clinical teams together may be more impactful for cultural shifts needed for changing clinical practice.

Screening for sleep disordered breathing among children hospitalized for asthma exacerbation.

BACKGROUND: Sleep disordered breathing (SDB) may exacerbate asthma and is a treatable comorbidity. OBJECTIVE: To design and implement a screening process for SDB in patients hospitalized for asthma exacerbation using quality improvement (QI) methods. We sought to improve screening for SDB from zero to 60% from July 2019 to December 2020. DESIGN/METHODS: A multidisciplinary team used QI methods to screen for SDB using the Michigan pediatric sleep questionnaire (PSQ) in patients 2-18 years hospitalized for asthma exacerbation. Key interventions included: pairing the PSQ screen with another element of routine care (the asthma risk factor screen), educating staff and physicians, engaging respiratory therapists to complete the PSQ and document scores, and modifying the electronic medical record (asthma order set and flowsheet for PSQ score documentation). A run chart tracked progress and descriptive statistics were generated. RESULTS: There were 2067 patients admitted for asthma exacerbation during this project. The PSQ was completed for 1531 patients (74%) overall. Of screened patients, 360 (24%) had a positive PSQ; the mean age was 8.6 years. Approximately 14 months after the project began, ~90% of children admitted for asthma were being screened; subsequently, >80% of patients were being screened until May 2022. Screening with the PSQ occurred approximately 90% of the time when routine asthma risk screens were completed. CONCLUSION: A screening process for SDB was successfully implemented and appeared feasible and sustainable. The high proportion of positive screens reinforces the importance of evaluating for SDB in the high-risk population of children requiring hospitalization for asthma exacerbation.

Pediatric Hospitalists' Performance of Recommended Minor Procedures: A Multicenter Study.

BACKGROUND AND OBJECTIVES: Performance of minor procedures is highly variable among pediatric hospitalists. Our objective was to describe procedural frequency and measure self-assessed competence in recommended minor procedures among practicing hospitalists. METHODS: An electronic survey was administered across 20 US institutions. An individual survey assessed training, frequency, independence, and success in performing 11 minor procedures. The site survey described practice settings at participating study sites. The primary outcome was respondents' self-assessed competence (SAC), derived by averaging self-assessed independence and success scores (each on a 5-point Likert scale) across all 11 minor procedures. Associations between predictor variables and SAC were determined through analysis of variance for categorical variables and fitted regression models for continuous variables. RESULTS: Of the 360 survey respondents, the majority were female (70%), not fellowship trained (78%), and had 10 years or fewer experience as a hospitalist (72%). Lumbar puncture and bag mask ventilation were most frequently performed. Greater procedural frequency and time since graduation from training were associated with higher SAC scores among respondents. Practice characteristics, including comanagement of patients and reserved time for practicing procedures, were associated with higher SAC scores. The presence of a simulation center and fellowship program was not associated with higher SAC scores. CONCLUSIONS: Pediatric hospitalists that performed procedures more frequently had higher self-assessed procedural competence. Tailored opportunities with increased hands-on experience in performing minor procedures may be important to develop and maintain procedural skills.

Standardizing electronic health record ventilation data in the pediatric long-term mechanical ventilator-dependent population.

BACKGROUND: Sharing data across institutions is critical to improving care for children who are using long-term mechanical ventilation (LTMV). Mechanical ventilation data are complex and poorly standardized. This lack of data standardization is a major barrier to data sharing. OBJECTIVE: We aimed to describe current ventilator data in the electronic health record (EHR) and propose a framework for standardizing these data using a common data model (CDM) across multiple populations and sites. METHODS: We focused on a cohort of patients with LTMV dependence who were weaned from mechanical ventilation (MV). We extracted and described relevant EHR ventilation data. We identified the minimum necessary components, termed "Clinical Ideas," to describe MV from time of initiation to liberation. We then utilized existing resources and partnered with informatics collaborators to develop a framework for incorporating Clinical Ideas into the PEDSnet CDM based on the Observational Medical Outcomes Partnership (OMOP). RESULTS: We identified 78 children with LTMV dependence who weaned from ventilator support. There were 25 unique device names and 28 unique ventilation mode names used in the cohort. We identified multiple Clinical Ideas necessary to describe ventilator support over time: device, interface, ventilation mode, settings, measurements, and duration of ventilation usage per day. We used Concepts from the SNOMED-CT vocabulary and integrated an existing ventilator mode taxonomy to create a framework for CDM and OMOP integration. CONCLUSION: The proposed framework standardizes mechanical ventilation terminology and may facilitate efficient data exchange in a multisite network. Rapid data sharing is necessary to improve research and clinical care for children with LTMV dependence.

An Initiative to Reduce Insulin-Related Adverse Drug Events in a Children's Hospital.

OBJECTIVES: Adverse drug events (ADEs) during hospitalization are common. Insulin-related events, specifically, are frequent and preventable. At a tertiary children's hospital, we sought to reduce insulin-related ADEs by decreasing the median event rate of hyper- and hypoglycemia over a 12-month period. METHODS: Using Lean 6 σ methodology, we instituted a house-wide process change from a single-order ordering process to a pro re nata (PRN) standing order process. The standardized process included parameters for administration and intervention, enabling physician and nursing providers to practice at top of licensure. Automated technology during dose calculation promoted patient safety during dual verification processes. Control charts tracked rates of insulin-related ADEs, defined as hyperglycemia (glucose level >250 mg/dL) or hypoglycemia (glucose level <65 mg/dL). Events were standardized according to use rates of insulin on each nursing unit. The rates of appropriately timed insulin doses (within 30 minutes of a blood sugar check) were assessed. RESULTS: Baseline median house-wide frequencies of hyperglycemic and hypoglycemic episodes were 55 and 6.9 events (per 100 rapid-acting insulin days), respectively. The median time to insulin administration was 32 minutes. The implementation of the PRN process reduced the median frequencies of hyperglycemic and hypoglycemic episodes to 45 and 3.8 events, respectively. The median time to insulin administration decreased to 18 minutes. CONCLUSIONS: A PRN ordering process and education decreased insulin-associated ADEs and the time to insulin dosing compared with single-entry processes. Engaging bedside providers was instrumental in reducing insulin-related ADEs. Strategies that decrease the time from patient assessment to drug administration should be studied for other high-risk drugs.

Dexamethasone Versus Prednisone in Children Hospitalized With Asthma Exacerbation.

OBJECTIVES: Dexamethasone is increasingly used for the management of children hospitalized with asthma in place of prednisone, yet data regarding the effectiveness of dexamethasone in children with asthma exacerbation severe enough to require hospitalization are limited. Our objective is to compare the effectiveness of dexamethasone versus prednisone in children hospitalized with an asthma exacerbation on 30-day reutilization. METHODS: We conducted a retrospective cohort study at an urban, quaternary children's hospital of children aged 4 to 17 years, hospitalized from January 1, 2014 to December 31, 2017, with a primary discharge diagnosis of asthma. A covariate-balanced propensity score was derived to account for physician discretion in steroid selection. A generalized linear model, including inverse probability treatment weighting, was used to detect differences in 30-day return utilization (unplanned readmission or emergency department visit) between children whose first dose of corticosteroid was dexamethasone versus prednisone. RESULTS: Inclusion criteria were met by 1161 patients, of which 510 (44%) first received dexamethasone versus 651 (56%) who first received prednisone. The total cohort had a mean age of 8.5 years (SD 3.4). The covariate-balanced cohort had no significant differences in demographic characteristics or illness severity between groups. The dexamethasone group had a return utilization of 3.9% (20 of 510) versus 2.2% (14 of 651) for children treated with prednisone. The propensity score-adjusted analysis revealed the steroid treatment was not found to significantly affect the 30-day reutilization (adjusted odds ratio [aOR] 1.61; 95%CI 0.80-3.31). CONCLUSIONS: The initial steroid choice (dexamethasone versus prednisone) was not associated with 30-day reutilization after hospitalization for an asthma exacerbation.

Improving Home Ventilator Alarm Use Among Children Requiring Chronic Mechanical Ventilation.

BACKGROUND AND OBJECTIVES: Children requiring long-term mechanical ventilation are at high risk of mortality. Setting ventilator alarms may improve safety, but best practices for setting ventilator alarms have not been established. Our objective was to increase the mean proportion of critical ventilator alarms set for those children requiring chronic mechanical ventilation followed in our pulmonary clinic from 63% to >90%. METHODS: Using the Institute for Healthcare Improvement Model for Improvement, we developed, tested, and implemented a series of interventions using Plan-Do-Study-Act cycles. We followed our progress using statistical process control methods. Our primary interventions were: (1) standardization of the clinic workflow, (2) development of an algorithm to guide physicians in selecting and setting ventilator alarms, (3) updating that algorithm based on review of failures and inpatient testing, and (4) enhancing staff engagement to change the culture surrounding ventilator alarms. RESULTS: We collected baseline data from May 1 to July 13, 2017 on 130 consecutive patients seen in the pulmonary medicine clinic. We found that 63% of critical ventilator alarms were set. Observation of the process, standardization of workflow, and adaptation of an alarm algorithm led to an increase to 85.7% of critical alarms set. Through revising our algorithm to include an apnea alarm, and maximizing provider engagement, more than 95% of critical ventilator alarms were set, exceeding our goal. We sustained this improvement through January 2021. CONCLUSIONS: Our stepwise approach, including process standardization, staff engagement, and integration of an alarm algorithm, improved the use of ventilator alarms in chronically ventilated pediatric patients.

Human papillomavirus vaccine and behavioural disinhibition.

OBJECTIVES: We sought to identify characteristics of parents who believe in sexual disinhibition and that Pap smears can safely be stopped after females receive the human papillomavirus (HPV) vaccine. METHODS: We surveyed 647 parents of adolescent girls living in areas of North Carolina with elevated rates of cervical cancer. We report data primarily from a survey conducted in October and November 2008. RESULTS: Only 16% (101/647) of parents agreed that teenage girls who receive HPV vaccine may be more likely to have sex. Parents who believed in vaccine-induced sexual disinhibition were more likely to be older (OR 1.89, 95% CI 1.09 to 3.26) or report conservative political views (OR 2.26, 95% CI 1.37 to 3.73). Parents were less likely to believe in sexual disinhibition if they had greater knowledge about HPV vaccine (OR 0.52, 95% CI 0.32 to 0.85) or if their daughters had received HPV vaccine (OR 0.31, 95% CI 0.17 to 0.57). While few parents (5%; 30/647) believed that women could safely stop getting regular Pap smears after receiving HPV vaccine, this belief was somewhat more common among racial and ethnic minority parents (16%) and among fathers (13%). CONCLUSIONS: Few parents believed that HPV vaccine is likely to lead to increased sexual activity among females or reduce the need for vaccinated women to have regular Pap smears in the future. Characterising parents who hold beliefs in behavioural disinhibition is important as clinicians encountering parents in practice may desire information about this population.

Effect of Adenotonsillectomy on Cardiac Function in Children Age 5-13 Years With Obstructive Sleep Apnea.

Changes in left ventricular structure and function have been previously described in children with obstructive sleep apnea (OSA). We aimed to determine if these structural and functional cardiac changes are reversible after treatment of OSA with adenotonsillectomy. Children aged 5 to 13 years with OSA and matched healthy controls were recruited. Adenotonsillectomy occurred within 1 month after diagnosis. Echocardiography and polysomnography were repeated postoperatively. Linear mixed models were fitted to echocardiography measures at baseline and follow-up to assess the effect of OSA on cardiac structure and function. These adjusted for age, gender, race, body mass index, systolic, and diastolic blood pressure. The study sample included 373 children, 199 with OSA and 174 healthy controls. In the control group, 114 children completed the study and 112 completed the study in the OSA group. Children with OSA had reduced diastolic function, lower systolic function, and greater left ventricular mass index at baseline compared with healthy controls (all p < 0.05). Measures of active relaxation, elastic recoil and lengthening of the left ventricle impacted overall diastolic function; each of these worsened with increasing OSA severity. Postoperatively, diastolic function improved in children with OSA compared with controls. There were not significant changes in LV mass index or geometry. In conclusion, children with OSA have impaired left ventricular relaxation during diastole indicating early stage diastolic dysfunction. Adenotonsillectomy for OSA signficantly improved diastolic function. Left ventricular remodeling did not change with improvement of OSA.
