The incidence of sports-and recreation-related concussions (SRRCs) in the United States is unknown. More than 44 million youth participate in sports annually, thus understanding the frequency of SRRCs in children is important on a population level. Our objective was to determine the number of SRRCs occurring annually among US youth ≤18 years old. METHODS:We identified SRRCs using 3 national databases: MarketScan, National Electronic Injury Surveillance System, and National High School Sports Related Injury Surveillance System, Reporting Injury Online. We determined the number of SRRCs seen in health care settings (outpatient, inpatient, and emergency department) and SRRCs reported to certified high school athletic trainers (ATCs). We used these data and findings in recently published literature to generate a national estimate of SRRCs. RESULTS:We estimate that between 1.1 and 1.9 million SRRCs occur annually in US children aged ≤18 years. Most children with SRRCs, 511 590 to 1 240 972, were not seen in health care settings. Of children with SRRCs seen in health care settings, most were seen as outpatients with 377 978 visits, compared with between 115 479 and 166 929 ED visits, and between 2886 and 4936 hospitalizations. CONCLUSIONS:This study provides the most accurate and precise estimate to date of the number of concussions among US children annually. SRRCs are a common injury in children. Providers in all health care settings need to be trained in concussion care. There is a need for better surveillance to enhance our understanding of the epidemiology of concussions in youth.

WHAT'S KNOWN ON THIS SUBJECT: Sports-and recreation-related concussions (SRRCs) are a common source of morbidity in children. Many of these injuries are not treated within health care settings. It is unknown how many SRRCs occur annually in the US. DOI WHAT THIS STUDY ADDS:We estimate between 1.1 and 1.9 million SRRCs occur annually in US children ≤18 years old. The magnitude of this number emphasizes the need for better national injury surveillance of the incidence of SRRCs.by guest on May 10, 2018 http://pediatrics.aappublications.org/ Downloaded from BRYAN et alConcussions, a form of traumatic brain injury (TBI), are common in children, with sports and recreation as a leading cause in this age group. 1, 2 The incidence of sports-and recreation-related concussions (SRRCs) in the United States is unknown; however, most epidemiologic studies indicate that a large number of SRRCs occur each year.

Treatment with 23.4% saline was associated with rapid reversal of transtentorial herniation (TTH) and reduced intracranial pressure, and had few adverse effects. Outcomes of TTH were poor, but medical reversal may extend the window for adjunctive treatments.

High adherence to bronchiolitis clinical pathway recommendations across care settings was associated with shorter LOS and lower cost.

A B S T R A C TOBJECTIVES: To assess (1) the accuracy of child immunization status documented by providers at hospital presentation for acute respiratory illness and (2) the association of provider-documented up-to-date (UTD) status with immunization receipt during and after hospitalization. METHODS:We conducted a retrospective cohort analysis of children #16 years old treated for asthma, croup, bronchiolitis, or pneumonia at a children's hospital between July 2014 and June 2016. Demographics, clinical characteristics, and provider-documented UTD immunization status (yes or no) at presentation were obtained from the medical record. We compared provider-documented UTD status to the gold standard: the child's UTD status as documented in the Washington State Immunization Information System (WAIIS). The sensitivity, specificity, and positive predictive value of provider-documented UTD status were calculated. We assessed the association of providerdocumented UTD status and immunization during and within 30 days posthospitalization using multivariable logistic regression. RESULTS:Among 478 eligible children, 450 (94%) had provider-documented UTD status at hospital presentation and an active WAIIS record. Overall, 92% and 42% were UTD by provider documentation and WAIIS records, respectively, with provider-documented UTD status having 98.4% sensitivity (95% confidence interval [CI]: 95.4%-99.7%), 12.2% specificity (95% CI: 8.5%-16.8%), and 44.6% positive predictive value (95% CI: 39.7%-49.5%). Per WAIIS records, 20% and 44% of children who were due for vaccines received a vaccine during or within 30 days posthospitalization, respectively. There was no significant association between provider-documented UTD status and immunization during or after hospitalization.CONCLUSIONS: Provider-documented UTD immunization status at hospital presentation for children with respiratory illnesses overestimates UTD status, creating missed opportunities for immunization during and after hospitalization.

OBJECTIVES: To examine the prevalence and safety of infant second-sleep practices. METHODS: A cross-sectional online survey of parents with infants ≤12 months assessed parent-reported sleep practices: position, use of a separate sleep surface, and sleep location at 2 time points (sleep onset and after nighttime waking). A composite score examined if all 3 safe sleep practices were used at each time point. Safe sleep was defined as: supine position, sleeping in a separate space, and in a crib, bassinet, cradle, or playard. Wilcoxon sign rank test was used to examine changes between the time points. Poisson regression models compared parents who reported a second-sleep location with those who did not. RESULTS: Of participants (n = 1500), 74% were female, 65% were White, 12% were Black, and 17% were of Hispanic ethnicity. Thirty-nine percent (n = 581) reported a second-sleep practice. Of parents who reported a second-sleep practice, 28% (n = 137) met all 3 safe sleep criteria at sleep onset; 9% (n = 42) met all 3 safe sleep criteria at both time points. A higher proportion of changes in sleep practices were to less-safe practices (P <.001). Factors associated with a second-sleep practice were parental age <25 years, parental race and ethnicity, first-time parents, homes with smoke exposure, and infants born at <37 weeks. CONCLUSIONS: Less than 10% of infants met all 3 safe sleep criteria at sleep onset and after nighttime waking. Interventions focused on safe sleep should highlight the importance of safe sleep practices after nighttime waking.

BACKGROUND AND OBJECTIVES There is a paucity of multicenter data on rates of high flow nasal cannula (HFNC) usage in bronchiolitis in the United States, largely because of the absence of standardized coding, with HFNC often subsumed into the larger category of noninvasive mechanical ventilation. METHODS We examined HFNC utilization in patients with bronchiolitis from a sample of hospitals participating in a national bronchiolitis quality improvement collaborative. Medical records of patients aged <2 years admitted November 2019 to March 2020 were reviewed and hospital-specific bronchiolitis policies were collected. Exclusion criteria were prematurity <32 weeks, any use of mechanical ventilation, and presence of comorbidities. HFNC utilization (including initiation, initiation location, and treatment duration), and hospital length of stay (LOS) were calculated. HFNC utilization was analyzed by individual hospital HFNC policy characteristics. RESULTS Sixty-one hospitals contributed data on 8296 patients; HFNC was used in 52% (n = 4286) of admissions, with the most common initiation site being the emergency department (ED) (75%, n = 3226). Hospitals that limited HFNC use to PICUs had reduced odds of initiating HFNC (odds ratio, 0.3; 95% confidence interval [CI], 0.3 to 0.4). Hospitals with an ED protocol to delay HFNC initiation had shorter HFNC treatment duration (−12 hours; 95% CI, −15.6 to −8.8) and shorter LOS (−14.9 hours; 95% CI, −18.2 to −11.6). CONCLUSIONS HFNC was initiated in >50% of patients admitted with bronchiolitis in this hospital cohort, most commonly in the ED. In general, hospitals with policies to limit HFNC use demonstrated decreased odds of HFNC initiation, shorter HFNC duration, and reduced LOS compared with the study population.
