Stratification of risk for emergent intracranial abnormalities in children with headaches: a Pediatric Emergency Care Applied Research Network (PECARN) study protocol.

INTRODUCTION: Headache is a common chief complaint of children presenting to emergency departments (EDs). Approximately 0.5%-1% will have emergent intracranial abnormalities (EIAs) such as brain tumours or strokes. However, more than one-third undergo emergent neuroimaging in the ED, resulting in a large number of children unnecessarily exposed to radiation. The overuse of neuroimaging in children with headaches in the ED is driven by clinician concern for life-threatening EIAs and lack of clarity regarding which clinical characteristics accurately identify children with EIAs. The study objective is to derive and internally validate a stratification model that accurately identifies the risk of EIA in children with headaches based on clinically sensible and reliable variables. METHODS AND ANALYSIS: Prospective cohort study of 28 000 children with headaches presenting to any of 18 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). We include children aged 2-17 years with a chief complaint of headache. We exclude children with a clear non-intracranial alternative diagnosis, fever, neuroimaging within previous year, neurological or developmental condition such that patient history or physical examination may be unreliable, Glasgow Coma Scale score<14, intoxication, known pregnancy, history of intracranial surgery, known structural abnormality of the brain, pre-existing condition predisposing to an intracranial abnormality or intracranial hypertension, head injury within 14 days or not speaking English or Spanish. Clinicians complete a standardised history and physical examination of all eligible patients. Primary outcome is the presence of an EIA as determined by neuroimaging or clinical follow-up. We will use binary recursive partitioning and multiple regression analyses to create and internally validate the risk stratification model. ETHICS AND DISSEMINATION: Ethics approval was obtained for all participating sites from the University of Utah single Institutional Review Board. A waiver of informed consent was granted for collection of ED data. Verbal consent is obtained for follow-up contact. Results will be disseminated through international conferences, peer-reviewed publications, and open-access materials.

Delivery Strategies for Postpartum Care: A Systematic Review and Meta-analysis.

OBJECTIVE: To systematically review the effects of postpartum health care-delivery strategies on health care utilization and maternal outcomes. DATA SOURCES: We searched Medline, EMBASE, CENTRAL, CINAHL, and ClinicalTrials.gov for studies in the United States or Canada from inception to November 16, 2022. METHODS OF STUDY SELECTION: We used duplicate screening for studies comparing health care-delivery strategies for routine postpartum care on health care utilization and maternal outcomes. We selected health care utilization, clinical, and harm outcomes prioritized by stakeholder panels. TABULATION, INTEGRATION, AND RESULTS: We found 64 eligible studies (50 randomized controlled trials, 14 nonrandomized comparative studies; N=543,480). For general postpartum care, care location (clinic, at home, by telephone) did not affect depression or anxiety symptoms (low strength of evidence), and care integration (by multiple types of health care professionals) did not affect depression symptoms or substance use (low strength of evidence). Providing contraceptive care earlier (compared with later) was associated with greater implant use at 6 months (summary effect size 1.36, 95% CI 1.13-1.64) (moderate strength of evidence). Location of breastfeeding care did not affect hospitalization, other unplanned care utilization, or mental health symptoms (all low strength of evidence). Peer support was associated with higher rates of any or exclusive breastfeeding at 1 month and any breastfeeding at 3-6 months (summary effect size 1.10-1.22) but not other breastfeeding measures (all moderate strength of evidence). Care by a lactation consultant was associated with higher breastfeeding rates at 6 months (summary effect size 1.43, 95% CI 1.07-1.91) but not exclusive breastfeeding (all moderate strength of evidence). Use and nonuse of information technology for breastfeeding care were associated with comparable rates of breastfeeding (moderate strength of evidence). Testing reminders for screening or preventive care were associated with greater adherence to oral glucose tolerance testing but not random glucose or hemoglobin A 1c testing (moderate strength of evidence). CONCLUSION: Various strategies have been shown to improve some aspects of postpartum care, but future research is needed on the most effective care delivery strategies to improve postpartum health.

Health Insurance Coverage and Postpartum Outcomes in the US: A Systematic Review.

Importance: Approximately half of postpartum individuals in the US do not receive any routine postpartum health care. Currently, federal Medicaid coverage for pregnant individuals lapses after the last day of the month in which the 60th postpartum day occurs, which limits longer-term postpartum care. Objective: To assess whether health insurance coverage extension or improvements in access to health care are associated with postpartum health care utilization and maternal outcomes within 1 year post partum. Evidence Review: Medline, Embase, CENTRAL, CINAHL, and ClinicalTrials.gov were searched for US-based studies from inception to November 16, 2022. The reference lists of relevant systematic reviews were scanned for potentially eligible studies. Risk of bias was assessed using questions from the Cochrane Risk of Bias tool and the Risk of Bias in Nonrandomized Studies of Interventions tool. Strength of evidence (SoE) was assessed using the Agency for Healthcare Research and Quality Methods Guide. Findings: A total of 25 973 citations were screened and 28 mostly moderate-risk-of-bias nonrandomized studies were included (3 423 781 participants) that addressed insurance type (4 studies), policy changes that made insurance more comprehensive (13 studies), policy changes that made insurance less comprehensive (2 studies), and Medicaid expansion (9 studies). Findings with moderate SoE suggested that more comprehensive association was likely associated with greater attendance at postpartum visits. Findings with low SoE indicated a possible association between more comprehensive insurance and fewer preventable readmissions and emergency department visits. Conclusions and Relevance: The findings of this systematic review suggest that evidence evaluating insurance coverage and postpartum visit attendance and unplanned care utilization is, at best, of moderate SoE. Future research should evaluate clinical outcomes associated with more comprehensive insurance coverage.

Postpartum Home Blood Pressure Monitoring: A Systematic Review.

OBJECTIVE: To assess the effectiveness of postpartum home blood pressure (BP) monitoring compared with clinic-based follow-up and the comparative effectiveness of alternative home BP-monitoring regimens. DATA SOURCES: Search of Medline, Cochrane, EMBASE, CINAHL, and ClinicalTrials.gov from inception to December 1, 2022, searching for home BP monitoring in postpartum individuals. METHODS OF STUDY SELECTION: We included randomized controlled trials (RCTs), nonrandomized comparative studies, and single-arm studies that evaluated the effects of postpartum home BP monitoring (up to 1 year), with or without telemonitoring, on postpartum maternal and infant outcomes, health care utilization, and harm outcomes. After double screening, we extracted demographics and outcomes to SRDR+. TABULATION, INTEGRATION, AND RESULTS: Thirteen studies (three RCTs, two nonrandomized comparative studies, and eight single-arm studies) met eligibility criteria. All comparative studies enrolled participants with a diagnosis of hypertensive disorders of pregnancy. One RCT compared home BP monitoring with bidirectional text messaging with scheduled clinic-based BP visits, finding an increased likelihood that at least one BP measurement was ascertained during the first 10 days postpartum for participants in the home BP-monitoring arm (relative risk 2.11, 95% CI 1.68-2.65). One nonrandomized comparative study reported a similar effect (adjusted relative risk [aRR] 1.59, 95% CI 1.36-1.77). Home BP monitoring was not associated with the rate of BP treatment initiation (aRR 1.03, 95% CI 0.74-1.44) but was associated with reduced unplanned hypertension-related hospital admissions (aRR 0.12, 95% CI 0.01-0.96). Most patients (83.3-87.0%) were satisfied with management related to home BP monitoring. Home BP monitoring, compared with office-based follow-up, was associated with reduced racial disparities in BP ascertainment by approximately 50%. CONCLUSION: Home BP monitoring likely improves ascertainment of BP, which is necessary for early recognition of hypertension in postpartum individuals, and may compensate for racial disparities in office-based follow-up. There is insufficient evidence to conclude that home BP monitoring reduces severe maternal morbidity or mortality or reduces racial disparities in clinical outcomes.

International variation in evidence-based emergency department management of bronchiolitis: a retrospective cohort study.

OBJECTIVES: We aimed to evaluate the international variation in the use of evidence-based management (EBM) in bronchiolitis. We hypothesised that management consistent with full-EBM practices is associated with the research network of care, adjusted for patient-level characteristics. Secondary objectives were to determine the association between full-EBM and (1) hospitalisation and (2) emergency department (ED) revisits resulting in hospitalisation within 21 days. DESIGN: A secondary analysis of a retrospective cohort study. SETTING: 38 paediatric EDs belonging to the Paediatric Emergency Research Network in Canada, USA, Australia/New Zealand UK/Ireland and Spain/Portugal. PATIENTS: Otherwise healthy infants 2-11 months old diagnosed with bronchiolitis between 1 January 2013 and 31 December, 2013. OUTCOME MEASURES: Primary outcome was management consistent with full-EBM, that is, no bronchodilators/corticosteroids/antibiotics, no chest radiography or laboratory testing. Secondary outcomes included hospitalisations during the index and subsequent ED visits. RESULTS: 1137/2356 (48.3%) infants received full-EBM (ranging from 13.2% in Spain/Portugal to 72.3% in UK/Ireland). Compared with the UK/Ireland, the adjusted ORs (aOR) of full-EBM receipt were lower in Spain/Portugal (aOR 0.08, 95% CI 0.02 to 0.29), Canada (aOR 0.13 (95% CI 0.06 to 0.31) and USA (aOR 0.16 (95% CI 0.07 to 0.35). EBM was less likely in infants with dehydration (aOR 0.49 (95% CI 0.33 to 0.71)), chest retractions (aOR 0.69 (95% CI 0.52 to 0.91)) and nasal flaring (aOR 0.69 (95% CI 0.52 to 0.92)). EBM was associated with reduced odds of hospitalisation at the index visit (aOR 0.77 (95% CI 0.60 to 0.98)) but not at revisits (aOR 1.17 (95% CI 0.74 to 1.85)). CONCLUSIONS: Infants with bronchiolitis frequently do not receive full-EBM ED management, particularly those outside of the UK/Ireland. Furthermore, there is marked variation in full-EBM between paediatric emergency networks, and full-EBM delivery is associated with lower likelihood of hospitalisation. Given the global bronchiolitis burden, international ED-focused deimplementation of non-indicated interventions to enhance EBM is needed.

Pharmacotherapy interventions for adolescent co-occurring substance use and mental health disorders: a systematic review.

BACKGROUND: Co-occurring mental health and substance use (SU) disorders among adolescents are common, with two-thirds of adolescents who seek SU treatment also requiring support for mental health. Primary care physicians play a key role in the pharmacological treatment of mental health disorders among adolescents, however, little is known about the impact of these treatments on SU outcomes. OBJECTIVES: This systematic review summarizes the evidence regarding commonly used pharmacotherapy interventions for mental health and their impact on adolescent SU. METHODS: Literature searches were conducted across five databases as part of a larger systematic review of adolescent SU interventions. Studies were screened for eligibility by two researchers, and study data were extracted regarding study design, patient and treatment characteristics and results. Risk of bias analyses and qualitative syntheses were completed to evaluate the strength of the evidence and the impact of pharmacotherapy on SU outcomes. RESULTS: Ten randomized controlled trials exploring seven pharmacotherapies met criteria for inclusion. All studies had low to moderate risk of bias. Four studies evaluated pharmacotherapy for co-occurring depression and SU, three evaluated attention deficit hyperactivity disorder and SU, and three evaluated bipolar disorder and SU. Five of the 10 studies also included a behavioural intervention. We found no evidence that pharmacotherapy for co-occurring mental health diagnoses impacted SU. CONCLUSION: Family medicine clinicians prescribing pharmacotherapy for mental health should be aware that additional interventions will likely be needed to address co-occurring SU.

Many adolescents have both mental health and substance use problems. Adolescents have difficulty getting effective treatment for both substance use and mental health concerns, in part because these treatments are often offered separately. Primary care physicians, who often care for adolescents with mental health concerns, may prescribe medications for diagnoses such as attention deficit hyperactivity disorder, depression or early symptoms of bipolar disorder. However, there is little research indicating whether these medications are helpful for co-occurring substance use disorder symptoms. This paper presents a review of existing research on medications used to treat common mental health disorders to evaluate their effect on substance use. Ten studies address this question and suggest that medications for mental health are insufficient for helping adolescents with substance use disorders or substance use problems.

Effectiveness of medication for opioid use disorders in transition-age youth: A systematic review.

BACKGROUND: Sequalae of opioid misuse constitute a public health emergency in the United States. A robust evidence base informs the use of medication for opioid use disorders (MOUD) in adults, with far less research in transition-age youth. This systematic review evaluates the effectiveness of MOUD for transition-age youth (age 16 to 25). METHODS: This synthesis was part of a larger systematic review focused on adolescent substance use interventions. The study team conducted literature searches in MEDLINE, the Cochrane CENTRAL Registry of Controlled Trials, EMBASE, PsycINFO, and CINAHL through October 31, 2019. We screened studies, extracted data, and assessed risk of bias using standard methods. The primary and secondary outcomes were the effect of MOUD on opioid abstinence and treatment retention, respectively. RESULTS: The study team screened a total of 33,272 records and examined 1831 full-text articles. Four randomized trials met criteria for inclusion in the current analysis. All four trials assessed a combination of buprenorphine plus cognitive behavioral therapy versus a comparison condition. Some trials included additional behavioral interventions, and the specific duration/dosage of buprenorphine varied. Risk of bias was moderate for all studies. Studies found that buprenorphine was more effective than clonidine, effectively augmented by memantine, and that longer medication taper durations were more effective than shorter tapers in promoting both abstinence and retention. Notably, we did not identify any studies of methadone or naltrexone, adjunctive behavioral interventions were sparingly described, and treatment durations were far shorter than recommended guidelines in adults. DISCUSSION: The literature guiding youth MOUD is limited, and more research should evaluate the effectiveness of options other than buprenorphine, optimal treatment duration, and the benefit of adjunctive behavioral interventions. Subgroup analyses of extant randomized clinical trials could help to extend knowledge of MOUD effectiveness in this age cohort.

Making Narrative Statements to Describe Treatment Effects.

Accurately describing treatment effects using plain language and narrative statements is a critical step in communicating research findings to end users. However, the process of developing these narratives has not been historically guided by a specific framework. The Agency for Healthcare Research and Quality Evidence-based Practice Center Program developed guidance for narrative summaries of treatment effects that identifies five constructs. We explicitly identify these constructs to facilitate developing narrative statements: (1) direction of effect, (2) size of effect, (3) clinical importance, (4) statistical significance, and (5) strength or certainty of evidence. These constructs clearly overlap. It may not always be feasible to address all five constructs. Based on context and intended audience, investigators can determine which constructs will be most important to address in narrative statements.

Brief Behavioral Interventions for Substance Use in Adolescents: A Meta-analysis.

CONTEXT: Adolescents with problematic substance use (SU) are at risk for far-reaching adverse outcomes. OBJECTIVE: Synthesize the evidence regarding the effects of brief behavioral interventions for adolescents (12-20 years) with problematic SU. DATA SOURCES: We conducted literature searches in Medline, the Cochrane Central Register of Controlled Trials, Embase, Cumulative Index to Nursing and Allied Health Literature, and PsycInfo through October 31, 2019. STUDY SELECTION: We screened 33 272 records and citations for interventions in adolescents with at least problematic SU, retrieved 1831 articles, and selected 22 randomized controlled trials of brief interventions meeting eligibility criteria for meta-analysis. DATA EXTRACTION: We followed Agency for Healthcare Research and Quality guidelines. We categorized brief interventions into components, including motivational interviewing (MI), psychoeducation, and treatment as usual. Outcomes included SU (abstinence, days used per month) for alcohol and cannabis, and substance-related problem scales. Strength of evidence (SoE) was assessed. RESULTS: Both pairwise and network meta-analyses were conducted by using random effects models. Compared to treatment as usual, the use of MI reduces heavy alcohol use days by 0.7 days per month (95% credible interval [CrI]: -1.6 to 0.02; low SoE), alcohol use days by 1.1 days per month (95% CrI -2.2 to -0.3; moderate SoE), and overall substance-related problems by a standardized net mean difference of 0.5 (95% CrI -1.0 to 0; low SoE). The use of MI did not reduce cannabis use days, with a net mean difference of -0.05 days per month (95% CrI: -0.26 to 0.14; moderate SoE). LIMITATIONS: There was lack of consistently reported outcomes and limited available comparisons. CONCLUSIONS: The use of MI reduces heavy alcohol use, alcohol use days, and SU-related problems in adolescents but does not reduce cannabis use days.

International Practice Patterns of Antibiotic Therapy and Laboratory Testing in Bronchiolitis.

BACKGROUND AND OBJECTIVES: International patterns of antibiotic use and laboratory testing in bronchiolitis in emergency departments are unknown. Our objective is to evaluate variation in the use of antibiotics and nonindicated tests in infants with bronchiolitis in 38 emergency departments in Pediatric Emergency Research Networks in Canada, the United States, Australia and New Zealand, the United Kingdom and Ireland, and Spain and Portugal. We hypothesized there would be significant variation, adjusted for patient characteristics. METHODS: We analyzed a retrospective cohort study of previously healthy infants aged 2 to 12 months with bronchiolitis. Variables examined included network, poor feeding, dehydration, nasal flaring, chest retractions, apnea, saturation, respiratory rate, fever, and suspected bacterial infection. Outcomes included systemic antibiotic administration and urine, blood, or viral testing or chest radiography (CXR). RESULTS: In total, 180 of 2359 (7.6%) infants received antibiotics, ranging from 3.5% in the United Kingdom and Ireland to 11.1% in the United States. CXR (adjusted odds ratio [aOR] 2.3; 95% confidence interval 1.6-3.2), apnea (aOR 2.2; 1.1-3.5), and fever (aOR 2.4; 1.7-3.4) were associated with antibiotic use, which did not vary across networks (P = .15). In total, 768 of 2359 infants (32.6%) had ≥1 nonindicated test, ranging from 12.7% in the United Kingdom and Ireland to 50% in Spain and Portugal. Compared to the United Kingdom and Ireland, the aOR (confidence interval) results for testing were Canada 5.75 (2.24-14.76), United States 4.14 (1.70-10.10), Australia and New Zealand 2.25 (0.86-5.74), and Spain and Portugal 3.96 (0.96-16.36). Testing varied across networks (P < .0001) and was associated with suspected bacterial infections (aOR 2.12; 1.30-2.39) and most respiratory distress parameters. Viral testing (591 of 768 [77%]) and CXR (507 of 768 [66%]) were obtained most frequently. CONCLUSIONS: The rate of antibiotic use in bronchiolitis was low across networks and was associated with CXR, fever, and apnea. Nonindicated testing was common outside of the United Kingdom and Ireland and varied across networks irrespective of patient characteristics.

Pharmacotherapy in bronchiolitis at discharge from emergency departments within the Pediatric Emergency Research Networks: a retrospective analysis.

BACKGROUND: Clinical guidelines advise against pharmacotherapy in bronchiolitis. However, little is known about global variation in prescribing practices for bronchiolitis at discharge from emergency departments. We aimed to evaluate global variation in prescribing practice (ie, inhaled salbutamol, or oral or inhaled corticosteroids) for infants with bronchiolitis at discharge from emergency departments. METHODS: We did a planned secondary analysis of a multinational, retrospective cohort study of the Pediatric Emergency Research Networks. Previously healthy infants (aged <12 months) who were discharged with bronchiolitis between Jan 1 and Dec 31, 2013 from 38 emergency departments in Australia and New Zealand, Canada, Spain and Portugal, the UK and Ireland, and the USA were included. The primary outcome was pharmacotherapy prescription at discharge from the emergency department. Secondary outcomes were revisits to the emergency department or hospitalisations for bronchiolitis within 21 days of discharge. FINDINGS: Of 1566 infants discharged from the emergency department, 317 (20%) were prescribed pharmacotherapy. Corticosteroid prescriptions were infrequent, ranging from 0% (0 of 68 infants) in Spain and Portugal to 6% (25 of 452) in the USA. Salbutamol prescriptions ranged from 5% (22 of 432) in the UK and Ireland to 32% (146 of 452) in the USA. Compared with the UK and Ireland, the odds of prescription of pharmacotherapy were increased in Spain and Portugal (odds ratio [OR] 9·22, 95% CI 1·70-49·96), the USA (8·20, 2·79-24·11), Canada (5·17, 1·61-16·67), and Australia and New Zealand (1·21, 0·36-4·10). After adjustment for clustering by site, pharmacotherapy at discharge was associated with older age (per 1 month increase; OR 1·23, 95% CI 1·16-1·30), oxygen saturation (per 1% decrease from 100%; 1·09, 1·01-1·18), chest retractions (1·88, 1·26-2·79), network (p=0·00050), and site (p<0·00090). 303 (19%) of 1566 infants returned to the emergency department and 129 (43%) of 303 were hospitalised. Discharge pharmacotherapy was not associated with revisits (p=0·55) or subsequent hospitalisations (p=0·50). INTERPRETATION: Use of ineffective medications in infants with bronchiolitis at discharge from emergency departments is common, with large differences in prescribing practices between countries and emergency departments. Enhanced knowledge translation and deprescribing efforts are needed to optimise and unify the management of bronchiolitis. FUNDING: None.

Comparison of Machine Learning Optimal Classification Trees With the Pediatric Emergency Care Applied Research Network Head Trauma Decision Rules.

Importance: Computed tomographic (CT) scanning is the standard for the rapid diagnosis of intracranial injury, but it is costly and exposes patients to ionizing radiation. The Pediatric Emergency Care Applied Research Network (PECARN) rules for identifying children with minor head trauma who are at very low risk of clinically important traumatic brain injury (ciTBI) are widely used to triage CT imaging. Objective: To examine whether optimal classification trees (OCTs), which are novel machine-learning classifiers, improve on PECARN rules' predictive accuracy. Design, Setting, and Participants: A secondary analysis of prospective, publicly available data on emergency department visits for head trauma used by the PECARN group to develop their tool was conducted to derive OCT-based prediction rules for ciTBI in a development cohort and compare their predictive performance vs the PECARN rules in a validation cohort among children who were younger than 2 years and 2 years or older. Data on 42 412 children with head trauma and without severely altered mental status who were examined between June 1, 2004, and September 30, 2006, were gathered from 25 emergency departments in North America participating in PECARN. Data analysis was conducted from September 15, 2016, to December 18, 2018. Main Outcomes and Measures: The outcome was ciTBI, with predictive performance measured by estimating the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio for the OCT and the PECARN rules. The OCT and PECARN rules' performance was compared by estimating ratios for each measure. Results: Of the 42 412 children (15 996 [37.7%] girls) included in the analysis, 10 718 were younger than 2 years (25.3%; mean [SD] age, 11.6 [0.6] months) and 31 694 were 2 years or older (74.7%; age, 9.1 [4.9] years). Compared with PECARN rules, OCTs misclassified 0 vs 1 child with ciTBI in the younger and 10 vs 9 children with ciTBI in the older cohort, and correctly identified more children with very low risk of ciTBI in the younger (7605 vs 5701) and older (20 594 vs 18 134) cohorts. In the validation cohorts, compared with the PECARN rules, the OCTs had statistically significantly better specificity (in the younger cohort: 69.3%; 95% CI, 67.4%-71.2% vs 52.8%; 95% CI, 50.8%-54.9%; in the older cohort: 65.6%; 95% CI, 64.5%-66.8% vs 57.6%; 95% CI, 56.4%-58.8%), positive predictive value (odds ratios, 1.54; 95% CI, 1.36-1.74 and 1.23; 95% CI, 1.17-1.30, in younger and older children, respectively), and positive likelihood ratio (risk ratios, 1.54; 95% CI, 1.36-1.74 and 1.23; 95% CI, 1.17-1.30, in younger and older children, respectively). There were no statistically significant differences in the sensitivity, negative predictive value, and negative likelihood ratio between the 2 sets of rules. Conclusions and Relevance: If implemented, OCTs may help reduce the number of unnecessary CT scans, without missing more patients with ciTBI than the PECARN rules.

"Full Stomach" Despite the Wait: Point-of-care Gastric Ultrasound at the Time of Procedural Sedation in the Pediatric Emergency Department.

OBJECTIVES: The objective was to use gastric point-of-care ultrasound (POCUS) to assess gastric contents and volume, summarize the prevalence of "full stomach," and explore the relationship between fasting time and gastric contents at the time of procedural sedation. METHODS: This was a prospective study of patients aged 2 to 17 years fasting prior to procedural sedation. A single sonographer scanned each patient's gastric antrum in two positions: supine with the upper body elevated and right lateral decubitus (RLD). Gastric content (empty, liquid, or solid) was noted, and the gastric volume (mL/kg) was estimated from antral cross-sectional area (CSA). "Full stomach" was defined as any solid content or >1.2 mL/kg of liquid gastric content. RESULTS: We enrolled 116 subjects, with a median fasting time of 5.8 hours. Of the 107 with evaluable images, 74 patients, 69% (95% confidence interval [CI] = 60%-77%), were categorized as having a full stomach. Each hour of fasting was associated with lower odds (odds ratio = 0.79, 95% CI = 0.65-0) of a full stomach. However, the knowledge of fasting time alone provides little ability to discriminate between risk groups (C-index = 0.66). CONCLUSIONS: Gastric POCUS classified many patients as having a full stomach at the time of expected procedural sedation, despite prolonged fasting times. These findings may inform risk-benefit considerations when planning the timing and medication choice for procedural sedation.

Emergency Department Visits Owing to Intentional and Unintentional Traumatic Brain Injury among Infants in the United States: A Population-Based Assessment.

OBJECTIVE: To examine national trends of emergency department (ED) visits owing to traumatic brain injury (TBI) among infants (age <12 months), specifically in the context of intentional and unintentional mechanisms. STUDY DESIGN: National Electronic Injury Surveillance System-All Injury Program data documenting nonfatal ED visits from 2003 to 2012 were analyzed. TBI was defined as ED visits resulting in a diagnosis of concussion, or fracture, or internal injury of the head. Intentional and unintentional injury mechanisms were compared using multivariable models. Joinpoint regression was used to identify significant time trends. RESULTS: TBI-related ED visits (estimated n = 713 124) accounted for 28% of all injury-related ED visits by infants in the US, yielding an average annual rate of 1722 TBI-related ED visits per 100 000 infants. Trend analysis showed an annual increase of 9.48% in the rate of TBI-related ED visits over 10 years (P < .05). For these visits, an estimated 701 757 (98.4%) were attributed to unintentional mechanisms and 11 367 (1.6%) to intentional mechanisms. Unintentional TBI-related ED visit rates increased by 9.52% annually (P < .05) and the rates of intentional TBI were relatively stable from 2003 to 2012. Infants with intentional TBI were more likely to be admitted (aOR, 11.44; 95% CI, 3.02-21.75) compared with those with unintentional TBI. CONCLUSIONS: The rate of TBI-related ED visits in infants increased primarily owing to unintentional mechanisms and intentional TBI-related ED visits remained stable over the decade. Improved strategies to reduce both intentional and unintentional injuries in infants are required.

Predicting Escalated Care in Infants With Bronchiolitis.

BACKGROUND AND OBJECTIVES: Early risk stratification of infants with bronchiolitis receiving airway support is critical for focusing appropriate therapies, yet the tools to risk categorize this subpopulation do not exist. Our objective was to identify predictors of "escalated care" in bronchiolitis. We hypothesized there would be a significant association between escalated care and predictors in the emergency department. We subsequently developed a risk score for escalated care. METHODS: We conducted a retrospective cohort study of previously healthy infants aged <12 months with bronchiolitis. Our primary outcome was escalated care (ie, hospitalization with high-flow nasal cannula, noninvasive or invasive ventilation, or intensive care admission). The predictors evaluated were age, prematurity, day of illness, poor feeding, dehydration, apnea, nasal flaring and/or grunting, respiratory rate, oxygen saturation, and retractions. RESULTS: Of 2722 patients, 261 (9.6%) received escalated care. Multivariable predictors of escalated care were oxygen saturation <90% (odds ratio [OR]: 8.9 [95% confidence interval (CI) 5.1-15.7]), nasal flaring and/or grunting (OR: 3.8 [95% CI 2.6-5.4]), apnea (OR: 3.0 [95% CI 1.9-4.8]), retractions (OR: 3.0 [95% CI 1.6-5.7]), age ≤2 months (OR: 2.1 [95% CI 1.5-3.0]), dehydration (OR 2.1 [95% CI 1.4-3.3]), and poor feeding (OR: 1.9 [95% CI 1.3-2.7]). One of 217 (0.5%) infants without predictors received escalated care. The risk score ranged from 0 to 14 points, with the estimated risk of escalated care from 0.46% (0 points) to 96.9% (14 points). The area under the curve was 85%. CONCLUSIONS: We identified variables measured in the emergency department predictive of escalated care in bronchiolitis and derived a risk score to stratify risk of this outcome. This score may be used to aid management and disposition decisions.

Point-of-Care Ultrasound Assessment of Bladder Fullness for Female Patients Awaiting Radiology-Performed Transabdominal Pelvic Ultrasound in a Pediatric Emergency Department: A Randomized Controlled Trial.

STUDY OBJECTIVE: Radiology-performed transabdominal pelvic ultrasound, used to evaluate female patients with suspected pelvic pathology in the pediatric emergency department (ED), is often delayed by the need to fill the bladder. We seek to determine whether point-of-care ultrasound assessment of bladder fullness can predict patient readiness for transabdominal pelvic ultrasound more quickly than patient sensation of bladder fullness. METHODS: We performed a randomized controlled trial of female patients aged 8 to 18 years who required transabdominal pelvic ultrasound in a pediatric ED. Patients were randomized to usual care or point-of-care ultrasound and then assessed every 30 minutes for subjective bladder fullness (0 to 4 ordinal scale) and qualitative bladder fullness by point-of-care ultrasound. Patients were sent for pelvic ultrasound when they reported 3 or 4 on the subjective fullness scale (usual care) or a large bladder was visualized (point-of-care ultrasound). Primary outcome was time from enrollment to completion of pelvic ultrasound. Secondary outcome was success rate of pelvic ultrasound on first attempt. RESULTS: One hundred twenty patients were randomized and 117 had complete outcomes (59 usual care, 58 point-of-care ultrasound). Kaplan-Meier curves differed between groups (P<.001). Median time to successful completion of pelvic ultrasound was 139 minutes (usual care) and 87.5 minutes (point-of-care ultrasound), with difference in medians 51.5 minutes (95% confidence interval [CI] 23.4 to 77.2 minutes). All point-of-care ultrasound patients had successful transabdominal pelvic ultrasound on the first attempt compared with 84.7% in the usual care group, with difference -15.3% (95% Bayesian credible interval -5.3% to -25.0%). Weighted κ for interrater agreement was 0.83 (95% CI 0.79 to 0.87). CONCLUSION: Point-of-care ultrasound assessment of bladder fullness decreases time to transabdominal pelvic ultrasound and improves first-attempt success rate for female patients in the pediatric ED.

Survival after in-hospital cardiac arrest among cerebrovascular disease patients.

Stroke is a leading cause of death and disability, and while preferences for cardiopulmonary resuscitation (CPR) are frequently discussed, there is limited evidence detailing outcomes after CPR among acute cerebrovascular neurology (inclusive of stroke, subarachnoid hemorrhage (SAH)) patients. Systematic review and meta-analysis of PubMed and Cochrane libraries from January 1990 to December 2016 was conducted among stroke patients undergoing in-hospital CPR. Primary data from studies meeting inclusion criteria at two levels were extracted: 1) studies reporting survival to hospital discharge after CPR with cerebrovascular primary admitting diagnosis, and 2) studies reporting survival to hospital discharge after CPR with cerebrovascular comorbidity. Meta-analysis generated weighted, pooled survival estimates for each population. Of 818 articles screened, there were 176 articles (22%) that underwent full review. Three articles met primary inclusion criteria, with an estimated 8% (95% Confidence Interval (CI) 0.01, 0.14) rate of survival to hospital discharge from a pooled sample of 561 cerebrovascular patients after in-hospital CPR. Twenty articles met secondary inclusion criteria, listing a cerebrovascular comorbidity, with an estimated rate of survival to hospital discharge of 16% (95% CI 0.14, 0.19). All studies demonstrated wide variability in adherence to Utstein guidelines, and neurological outcomes were detailed in only 6 (26%) studies. Among the few studies reporting survival to hospital discharge after CPR among acute cerebrovascular patients, survival is lower than general inpatient populations. These findings synthesize the limited empirical basis for discussions about resuscitation among stroke patients, and highlight the need for more disease stratified reporting of outcomes after inpatient CPR.

Practice Variation in Acute Bronchiolitis: A Pediatric Emergency Research Networks Study.

BACKGROUND AND OBJECTIVES: Studies characterizing hospitalizations in bronchiolitis did not identify patients receiving evidence-based supportive therapies (EBSTs). We aimed to evaluate intersite and internetwork variation in receipt of ≥1 EBSTs during the hospital management of infants diagnosed with bronchiolitis in 38 emergency departments of pediatric emergency research networks in Canada, the United States, Australia, New Zealand, the United Kingdom, Ireland, Spain, and Portugal. We hypothesized that there would be significant variation, adjusted for patient characteristics. METHODS: Retrospective cohort study of previously healthy infants aged <12 months with bronchiolitis. Our primary outcome was that hospitalization occurred with EBST (ie, parenteral fluids, oxygen, or airway support). RESULTS: Out of 3725 participants, 1466 (39%) were hospitalized, and 1023 out of 1466 participants (69.8%) received EBST. The use of EBST varied by site (P < .001; range 6%-99%, median 23%), but not by network (P = .2). Significant multivariable predictors and their odds ratios (ORs) were as follows: age (0.9), oxygen saturation (1.3), apnea (3.4), dehydration (3.2), nasal flaring and/or grunting (2.4), poor feeding (2.1), chest retractions (1.9), and respiratory rate (1.2). The use of pharmacotherapy and radiography varied by network and site (P < .001), with respective intersite ranges 2% to 79% and 1.6% to 81%. Compared with Australia and New Zealand, the multivariable OR for the use of pharmacotherapy in Spain and Portugal was 22.7 (95% confidence interval [CI]: 4.5-111), use in Canada was 11.5 (95% CI: 3.7-36), use in the United States was 6.8 (95% CI: 2.3-19.8), and use in the United Kingdom was 1.4 (95% CI: 0.4-4.2). Compared with United Kingdom, OR for radiography use in the United States was 4.9 (95% CI 2.0-12.2), use in Canada was 4.9 (95% CI 1.9-12.6), use in Spain and Portugal was 2.4 (95% CI 0.6-9.8), and use in Australia and New Zealand was 1.8 (95% CI 0.7-4.7). CONCLUSIONS: More than 30% of infants hospitalized with bronchiolitis received no EBST. The hospital site was a source of variation in all study outcomes, and the network also predicted the use of pharmacotherapy and radiography.

Effectiveness of Tympanostomy Tubes for Otitis Media: A Meta-analysis.

CONTEXT: Tympanostomy tube placement is the most common ambulatory surgery performed on children in the United States. OBJECTIVES: The goal of this study was to synthesize evidence for the effectiveness of tympanostomy tubes in children with chronic otitis media with effusion and recurrent acute otitis media. DATA SOURCES: Searches were conducted in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Embase, and the Cumulative Index to Nursing and Allied Health Literature. STUDY SELECTION: Abstracts and full-text articles were independently screened by 2 investigators. DATA EXTRACTION: A total of 147 articles were included. When feasible, random effects network meta-analyses were performed. RESULTS: Children with chronic otitis media with effusion treated with tympanostomy tubes compared with watchful waiting had a net decrease in mean hearing threshold of 9.1 dB (95% credible interval: -14.0 to -3.4) at 1 to 3 months and 0.0 (95% credible interval: -4.0 to 3.4) by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after placement of tympanostomy tubes. Associated adverse events are poorly defined and reported. LIMITATIONS: Sparse evidence is available, applicable only to otherwise healthy children. CONCLUSIONS: Tympanostomy tubes improve hearing at 1 to 3 months compared with watchful waiting, with no evidence of benefit by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after tympanostomy tube placement, but the evidence base is severely limited. The benefits of tympanostomy tubes must be weighed against a variety of associated adverse events.

Prevention and Treatment of Tympanostomy Tube Otorrhea: A Meta-analysis.

CONTEXT: Children with tympanostomy tubes often develop ear discharge. OBJECTIVE: Synthesize evidence about the need for water precautions (ear plugs or swimming avoidance) and effectiveness of topical versus oral antibiotic treatment of otorrhea in children with tympanostomy tubes. DATA SOURCES: Searches in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Excerpta Medica Database, and the Cumulative Index to Nursing and Allied Health Literature. STUDY SELECTION: Abstracts and full-text articles independently screened by 2 investigators. DATA EXTRACTION: 25 articles were included. RESULTS: One randomized controlled trial (RCT) in children assigned to use ear plugs versus no precautions reported an odds ratio (OR) of 0.68 (95% confidence interval, 0.37-1.25) for >1 episode of otorrhea. Another RCT reported an OR of 0.71 (95% confidence interval, 0.29-1.76) for nonswimmers versus swimmers. Network meta-analyses suggest that, relative to oral antibiotics, topical antibiotic-glucocorticoid drops were more effective: OR 5.3 (95% credible interval, 1.2-27). The OR for antibiotic-only drops was 3.3 (95% credible interval, 0.74-16). Overall, the topical antibiotic-glucocorticoid and antibiotic-only preparations have the highest probabilities, 0.77 and 0.22 respectively, of being the most effective therapies. LIMITATIONS: Sparse randomized evidence (2 RCTs) and high risk of bias for nonrandomized comparative studies evaluating water precautions. Otorrhea treatments include non-US Food and Drug Administration approved, off-label, and potentially ototoxic antibiotics. CONCLUSIONS: No compelling evidence of a need for water precautions exists. Cure rates are higher for topical drops than oral antibiotics.
