Hospitalization and Mortality due to Infection among United States Children and Adolescents with Systemic Lupus Erythematosus.

OBJECTIVE: We aimed to determine the frequency and types of infections in hospitalized children with childhood-onset systemic lupus erythematosus (cSLE), and to identify risk factors for intensive care unit (ICU) admission and mortality. METHODS: We conducted a retrospective study of youth 2-21 years of age with ICD codes for SLE during admission to a hospital participating in the Pediatric Health Information System, a database of United States children's hospitals, from 2009-2021. Generalized linear mixed effect models were used to identify risk factors for ICU admission and mortality among children hospitalized with infection. RESULTS: We identified 8,588 children with cSLE and ≥ 1 hospitalization. Among this cohort, there were 26,269 hospitalizations, of which 13% had codes for infections, a proportion which increased over time (p = 0.036). Bacterial pneumonia was the most common hospitalized infection. In-hospital mortality occurred in 0.4% (n=103) of cSLE hospitalizations for any indication and 2% of hospitalizations for infection (n=60). The highest mortality rates occurred with pneumocystis jirovecii pneumonia (21%) and other fungal infections (21%). Lupus nephritis and end-stage renal disease (ESRD) were associated with increased odds of ICU admission (OR [95% CI] 1.47 [1.2- 1.8]) and 2.4 [1.7-3.4]) among children admitted for serious infection. ESRD was associated with higher mortality, OR 2.34 [1.1-4.9]. CONCLUSION: Hospitalizations with codes for for infection comprised a small proportion of cSLE admissions but accounted for the majority of mortality. The proportion of hospitalizations for infection increased over time. Lupus nephritis and ESRD were risk factors for poor outcomes.

Epidemiology and Severity of Illness of MIS-C and Kawasaki Disease During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Multisystem inflammatory syndrome in children (MIS-C) is a novel, severe condition following severe acute respiratory syndrome coronavirus 2 infection. Large epidemiologic studies comparing MIS-C to Kawasaki disease (KD) and evaluating the evolving epidemiology of MIS-C over time are lacking. We sought to understand the illness severity of MIS-C compared with KD and evaluate changes in MIS-C illness severity over time during the coronavirus disease 2019 pandemic compared with KD. METHODS: We included hospitalizations of children with MIS-C and KD from April 2020 to May 2022 from the Pediatric Health Information System administrative database. Our primary outcome measure was the presence of shock, defined as the use of vasoactive/inotropic cardiac support or extracorporeal membrane oxygenation. We examined the volume of MIS-C and KD hospitalizations and the proportion of hospitalizations with shock over time using 2-week intervals. We compared the proportion of hospitalizations with shock in MIS-C and KD patients over time using generalized estimating equations adjusting for hospital clustering and age, with time as a fixed effect. RESULTS: We identified 4868 hospitalizations for MIS-C and 2387 hospitalizations for KD. There was a higher proportion of hospitalizations with shock in MIS-C compared with KD (38.7% vs 5.1%). In our models with time as a fixed effect, we observed a significant decrease in the odds of shock over time in MIS-C patients (odds ratio 0.98, P < .001) but not in KD patients (odds ratio 1.00, P = .062). CONCLUSIONS: We provide further evidence that MIS-C is a distinct condition from KD. MIS-C was a source of lower morbidity as the pandemic progressed.

Identifying and Validating Pediatric Hospitalizations for MIS-C Through Administrative Data.

BACKGROUND: Individual children's hospitals care for a small number of patients with multisystem inflammatory syndrome in children (MIS-C). Administrative databases offer an opportunity to conduct generalizable research; however, identifying patients with MIS-C is challenging. METHODS: We developed and validated algorithms to identify MIS-C hospitalizations in administrative databases. We developed 10 approaches using diagnostic codes and medication billing data and applied them to the Pediatric Health Information System from January 2020 to August 2021. We reviewed medical records at 7 geographically diverse hospitals to compare potential cases of MIS-C identified by algorithms to each participating hospital's list of patients with MIS-C (used for public health reporting). RESULTS: The sites had 245 hospitalizations for MIS-C in 2020 and 358 additional MIS-C hospitalizations through August 2021. One algorithm for the identification of cases in 2020 had a sensitivity of 82%, a low false positive rate of 22%, and a positive predictive value (PPV) of 78%. For hospitalizations in 2021, the sensitivity of the MIS-C diagnosis code was 98% with 84% PPV. CONCLUSION: We developed high-sensitivity algorithms to use for epidemiologic research and high-PPV algorithms for comparative effectiveness research. Accurate algorithms to identify MIS-C hospitalizations can facilitate important research for understanding this novel entity as it evolves during new waves.

Validation of a Process for Shared Decision-Making in Pediatrics.

OBJECTIVE: We sought to confirm, refute, or modify a 4-step process for implementing shared decision-making (SDM) in pediatrics that involves determining 1) if the decision includes >1 medically reasonable option; 2) if one option has a favorable medical benefit-burden ratio compared to other options; and 3) parents' preferences regarding the options; then 4) calibrating the SDM approach based on other relevant decision characteristics. METHODS: We videotaped a purposive sample of pediatric inpatient and outpatient encounters at a single US children's hospital. Clinicians from 7 clinical services (craniofacial, neonatology, oncology, pulmonary, pediatric intensive care, hospital medicine, and sports medicine) were eligible. English-speaking parents of children who participated in inpatient family care conferences or outpatient problem-oriented encounters with participating clinicians were eligible. We conducted individual postencounter interviews with clinician and parent participants utilizing video-stimulated recall to facilitate reflection of decision-making that occurred during the encounter. We utilized direct content analysis with open coding of interview transcripts to determine the salience of the 4-step SDM process and identify themes that confirmed, refuted, or modified this process. RESULTS: We videotaped 30 encounters and conducted 53 interviews. We found that clinicians' and parents' experiences of decision-making confirmed each SDM step. However, there was variation in the interpretation of each step and a need for flexibility in implementing the process depending on specific decisional contexts. CONCLUSIONS: The 4-step SDM process for pediatrics appears to be salient and may benefit from further guidance about the interpretation of each step and contextual factors that support a modified approach.

Does Exposure to Pediatrician or Parent Blog Content Influence Infant Safe Sleep Practices?

OBJECTIVE: To examine whether exposure to safe sleep recommendations using a blog format changed infant sleep practices. METHODS: We conducted a pilot randomized controlled trial via Qualtrics, a web-based platform, with a national sample of parents of children < 1 year old. Survey questions about infant sleep practices included: bed-sharing, location, position and objects present. Safe sleep was defined as not bed-sharing, in a crib, bassinet or playard, back positioning, and no other objects present except pacifiers. Participants were randomized to read one of the following: (1) pediatrician blog post, (2) parent blog post, or (3) no blog post. The blog posts contained the same content about infant sleep but varied by identified authorship. All participants received links to online content about safe sleep. Participants received a follow-up survey 2-4 weeks later with the same questions about infant sleep practices. We compared responses in pre- and post-surveys by type of blog post exposure using multivariable logistic regression models. RESULTS: The average infant age (n = 1500) was 6.6 months (Standard Deviation 3.3). Most participants (74%) were female; 77% were married; 65% identified as white Non-Hispanic, 12% were black and 17% were Hispanic. 47% (n = 711) completed both surveys. We identified no differences in the odds of any of the four safe sleep practices after exposure to safe sleep recommendations in blog post format. CONCLUSION: Although in-person advice has been associated with improved safe sleep practices, we did not identify changes in infant sleep practices after exposure to safe sleep advice using blog posts.

Urban-rural disparities in interfacility transfers for children during COVID-19.

PURPOSE: We aimed to identify temporal trends and differences in urban and rural pediatric interfacility transfers (IFTs) before and during the COVID-19 pandemic. METHODS: We conducted a cross-sectional analysis of IFT among children <18 years from January 2019 to June 2022 using the Pediatric Health Information System. The primary outcome was IFTs from general hospitals to referral children's hospitals. The primary exposure was patient rurality, defined by Rural-Urban Commuting Area codes. We categorized IFTs into medical, surgical, and mental health diagnoses and analyzed trends by month. We calculated observed-to-expected (O-E) ratios of pre-pandemic (March 2019-Feb 2020) transfers compared to pandemic year 1 (March 2020-Feb 2021) and year 2 (March 2021-February 2022) using Poisson modeling. FINDINGS: Of 419,250 IFTs, 18.8% (n = 78,751) were experienced by rural-residing children. The O-E ratio of IFT in year 1 for urban children was 14.0% (95% confidence interval [CI] 13.8, 14.2) and 14.8% (95% CI 14.4, 15.3) for rural children compared to pre-pandemic (P = .0001). In year 2, transfers rebounded with IFTs for rural-residing children increasing more than urban-residing children (101.7% [95% CI 100.1, 103.4] compared to 90.7% [95% CI 89.0, 90.4], P < .0001). For mental-health indications in year 2, rural transfer ratios were higher than urban, 126.8% (95% CI, 116.7, 137.6) compared to 113.7% (95% CI 109.9, 117.6), P = .0168. CONCLUSIONS: Pediatric IFTs decreased dramatically during pandemic year 1. In year 2, while medical and surgical transfers continued to lag pre-pandemic volumes, transfers for mental health indications significantly exceeded pre-pandemic levels, particularly among rural-residing children.

Safe Sleep Behaviors and Factors Associated With Infant Second Sleep Practices.

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.

Vaccine Administration in Children's Hospitals.

OBJECTIVES: To examine inpatient vaccine delivery across a national sample of children's hospitals. METHODS: We conducted a retrospective cohort study examining vaccine administration at 49 children's hospitals in the Pediatric Health Information System database. Children <18 years old admitted between July 1, 2017, and June 30, 2019, and age eligible for vaccinations were included. We determined the proportion of hospitalizations with ≥1 dose of any vaccine type administered overall and by hospital, the type of vaccines administered, and the demographic characteristics of children who received vaccines. We calculated adjusted hospital-level rates for each vaccine type by hospital. We used logistic and linear regression models to examine characteristics associated with vaccine administration. RESULTS: There were 1 185 667 children and 1 536 340 hospitalizations included. The mean age was 5.5 years; 18% were non-Hispanic Black, and 55% had public insurance. There were ≥1 vaccine doses administered in 12.9% (95% confidence interval: 12.8-12.9) of hospitalizations, ranging from 1% to 45% across hospitals. The most common vaccines administered were hepatitis B and influenza. Vaccine doses other than the hepatitis B birth dose and influenza were administered in 1.9% of hospitalizations. Children had higher odds of receiving a vaccine dose other than the hepatitis B birth dose or influenza if they were <2 months old, had public insurance, were non-Hispanic Black race, were medically complex, or had a length of stay ≥3 days. CONCLUSIONS: In this national study, few hospitalizations involved vaccine administration with substantial variability across US children's hospitals. Efforts to standardize inpatient vaccine administration may represent an opportunity to increase childhood vaccine coverage.

Variation in Dexamethasone Dosing and Use Outcomes for Inpatient Croup.

OBJECTIVES: Evaluate the association between dexamethasone dosing and outcomes for children hospitalized with croup. METHODS: This study was nested within a multisite prospective cohort study of children aged 6 months to 6 years admitted to 1 of 5 US children's hospitals between July 2014 and June /2016. Multivariable linear and logistic mixed-effects regression models were used to examine the association between the number of dexamethasone doses (1 vs >1) and outcomes (length of stay [LOS], cost, and 30-day same-cause reuse). All multivariable analyses included a site-specific random effect to account for clustering within hospital and were adjusted for age, sex, race and ethnicity, presenting severity, medical complexity, insurance, caregiver education, and hospital. In cost analyses, we controlled for LOS. RESULTS: Among 234 children hospitalized with croup, patient characteristics did not differ by number of doses. The proportion receiving >1 dose varied by hospital (range 27.9%-57.1%). In adjusted analyses, >1 dose was not associated with same-cause reuse (odds ratio 0.87 [95% confidence interval (CI): 0.26 to 2.95]) but was associated with 45% longer LOS (relative risk = 1.45 [95% CI: 1.30 to 1.62]). When we controlled for LOS, >1 dose was not associated with differential cost ($-31.2 [95% CI $-424.4 to $362.0]). Eighty-two (35%) children received dexamethasone before presentation. CONCLUSIONS: We found significant interhospital variation in dexamethasone dosing and LOS. When we controlled for severity on presentation, >1 dexamethasone dose was associated with longer LOS but not reuse. Although incomplete adjustment for severity is one possible explanation, some providers may routinely keep children hospitalized to administer multiple dexamethasone doses.

Facilitators and Barriers to Providing Vaccinations During Hospital Visits.

BACKGROUND: Many children are undervaccinated at the time of hospital admission. Our objective was to explore the facilitators and barriers to vaccinating during hospitalization. METHODS: We conducted qualitative interviews of parents, primary care pediatricians, emergency department (ED) physicians, and pediatric hospitalists. Parents of undervaccinated hospitalized children who were admitted through the ED were invited to participate. We used purposive sampling to identify physician participants. Semistructured interviews querying participants' perspectives on hospital-based vaccination were audiorecorded and transcribed. Parent demographics and physician practice characteristics were collected. Transcripts were analyzed for facilitators and barriers to vaccinating during acute hospital visits by using inductive content analysis. A conceptual framework was developed on the basis of the social ecological model. RESULTS: Twenty-one parent interviews and 10 physician interviews were conducted. Of parent participants, 86% were female; 76% were white. Physician participants included 3 primary care pediatricians, 3 ED physicians, and 4 hospitalists. Facilitators and barriers fell under 4 major themes: (1) systems-level factors, (2) physician-level factors, (3) parent-provider interactional factors, and (4) parent- and child-level factors. Parent participants reported a willingness to receive vaccines during hospitalizations, which aligned with physician participants' experiences. Another key facilitator identified by parent and physician participants was the availability of shared immunization data. Identified by parent and physician participants included the availability of shared immunization data. Barriers included being unaware that the child was vaccine-eligible, parental beliefs against vaccination, and ED and inpatient physicians' perceived lack of skills to effectively communicate with vaccine-hesitant parents. CONCLUSIONS: Parents and physicians identified several key facilitators and barriers to vaccinating during hospitalization. Efforts to provide inpatient vaccines need to address existing barriers.

Does the Narrative Voice Influence Parental Perceptions of Pediatrician Blogs?

OBJECTIVE: To determine parental perceptions of pediatrician blog posts by narrative voice. METHODS: Three blog posts each on 2 topics (vaccines and sleep) were written by an established physician blogger and varied by narrative voice (personal, third person objective and mixed). Topics were chosen to be applicable to all parents. Blog posts were evaluated by a communications expert, 2 research investigators, and 3 parents to confirm differences in narrative voice. We sampled parents of children 0 to 18 years old in 4 primary and subspecialty care clinics, and 1 inpatient medical unit. Participants were randomized to read 2 blog posts (1 per topic) that varied by narrative voice. Participants rated their perceptions of the accuracy, reliability, and appeal for each blog posts on a 5-point Likert Scale. The Kruskal-Wallis test was used to compare the distribution of parental rankings for accuracy, reliability, and appeal. RESULTS: The average participant age (n = 258) was 39.8 (SD 9.7), 83% were female. Blog posts written in the third person objective voice were rated as more accurate and reliable than those in the personal or mixed voice. There was effect modification by topic, with parents rating the sleep blog posts as more accurate than the vaccine blog posts. There was no difference in the appeal of information by narrative voice or topic of blog post. CONCLUSIONS: The narrative voice used to convey information on pediatrician blog posts can influence reader perception of accuracy and reliability. Physician bloggers can enhance parental trust of their content using study findings.

Associations Between Quality Measures and Outcomes for Children Hospitalized With Bronchiolitis.

OBJECTIVES: To use adherence to the Pediatric Respiratory Illness Measurement System (PRIMES) indicators to evaluate the strength of associations for individual indicators with length of stay (LOS) and cost for bronchiolitis. METHODS: We prospectively enrolled children with bronchiolitis at 5 children's hospitals between July 1, 2014, and June 30, 2016. We examined associations between adherence to each individual PRIMES indicator for bronchiolitis and LOS and cost. Sixteen indicators were included, 9 "overuse" indicators for care that should not occur and 7 "underuse" indicators for care that should occur. We performed mixed effects linear regression to examine the association between adherence to each individual indicator and LOS (hours) and cost (dollars). All models controlled for patient demographics, patient complexity, and hospital. RESULTS: We enrolled 699 participants. The mean age was 8 months; 56% were male, 38% were white, and 63% had public insurance. Three indicators were significantly associated with shorter LOS and lower cost. All 3 indicators were overuse indicators and related to laboratory testing: no blood cultures (adjusted mean difference in LOS: -24.3 hours; adjusted mean cost difference: -$731, P < .001), no complete blood cell counts (LOS: -17.8 hours; cost: -$399, P < .05), and no respiratory syncytial virus testing (LOS: -16.6 hours; cost: -$272, P < .05). Two underuse indicators were associated with higher cost: documentation of oral intake at discharge ($671, P < .01) and documentation of hospital follow-up ($538, P < .05). CONCLUSIONS: A subset of PRIMES quality indicators for bronchiolitis are strongly associated with improved outcomes and can serve as important measures for future quality improvement efforts.

Vaccination Status and Adherence to Quality Measures for Acute Respiratory Tract Illnesses.

OBJECTIVES: To assess the relationship between vaccination status and clinician adherence to quality measures for children with acute respiratory tract illnesses. METHODS: We conducted a multicenter prospective cohort study of children aged 0 to 16 years who presented with 1 of 4 acute respiratory tract illness diagnoses (community-acquired pneumonia, croup, asthma, and bronchiolitis) between July 2014 and June 2016. The predictor variable was provider-documented up-to-date (UTD) vaccination status. Our primary outcome was clinician adherence to quality measures by using the validated Pediatric Respiratory Illness Measurement System (PRIMES). Across all conditions, we examined overall PRIMES composite scores and overuse (including indicators for care that should not be provided, eg, C-reactive protein testing in community-acquired pneumonia) and underuse (including indicators for care that should be provided, eg, dexamethasone in croup) composite subscores. We examined differences in length of stay, costs, and readmissions by vaccination status using adjusted linear and logistic regression models. RESULTS: Of the 2302 participants included in the analysis, 92% were documented as UTD. The adjusted mean difference in overall PRIMES scores by UTD status was not significant (adjusted mean difference -0.3; 95% confidence interval: -1.9 to 1.3), whereas the adjusted mean difference was significant for both overuse (-4.6; 95% confidence interval: -7.5 to -1.6) and underuse (2.8; 95% confidence interval: 0.9 to 4.8) composite subscores. There were no significant adjusted differences in mean length of stay, cost, and readmissions by vaccination status. CONCLUSIONS: We identified lower adherence to overuse quality indicators and higher adherence to underuse quality indicators for children not UTD, which suggests that clinicians "do more" for hospitalized children who are not UTD.

Parental Perceptions of the Internet and Social Media as a Source of Pediatric Health Information.

OBJECTIVE: 1) To evaluate differences in how parents use the Internet and social media for health information by child age. 2) To examine parental perceptions of health information on social media. METHODS: We conducted a cross-sectional survey of parents of children 0 to 18 years seen in clinics and an inpatient medical unit. Survey questions focused on: patterns of Internet and social media use, for what topics, and parental ratings of the accuracy, reliability, and appeal of information from social media. Parents' responses were categorized by age of their youngest child in years (0-4, 5-11, 12-18). RESULTS: A total of 258 parents completed the survey. The mean age was 39.8 years, 83% were female, 59% were white. The most common topics parents read about online were: sleep, mental health, and car safety. Nearly all parents (96%) used social media, with 68% using social media for health information. There were no significant differences in the proportion of parents who reported using social media for health information by child age. Only half of parents discussed information from social media with their physician. Parents of children age ≥5 years rated health information on social media as significantly more accurate than parents of younger children. There were no significant differences in ratings of reliability and appeal by child age. CONCLUSIONS: Parents of children of all ages use social media for a variety of important topics related to child health. As many parents do not discuss it with their physician, there are missed opportunities for pediatricians to provide high-quality information.

Vaccination Status and Resource Use During Hospital Visits for Respiratory Illnesses.

OBJECTIVES: To evaluate variation in resource use for children with acute respiratory tract illness (ARTI) by vaccination status. METHODS: We conducted a retrospective cohort study of children 0 to 16 years of age at 5 children's hospitals with 1 of 4 ARTI diagnoses (pneumonia, croup, asthma, and bronchiolitis) between July 2014 and June 2016. The predictor variable was provider-documented up-to-date (UTD) vaccination status (yes or no). Outcomes were receipt of each of the following tests or treatments (yes or no): complete blood cell count, blood cultures, C-reactive protein (CRP) level testing, viral testing, influenza testing, pertussis testing, chest radiographs, neck radiographs, antibiotics, and corticosteroids. We generated multivariable logistic regression models to examine the associations between our predictor and outcomes. RESULTS: Of the 2302 participants included in analysis, 568 (25%) were diagnosed with pneumonia, 343 (15%) were diagnosed with croup, 653 (28%) were diagnosed with asthma, and 738 (32%) were diagnosed with bronchiolitis. Most (92%) vaccination statuses were documented as UTD. Across conditions, children whose vaccination status was documented as not UTD had higher adjusted odds of receiving a complete blood cell count, blood culture, CRP level testing, and influenza testing (P < .001). Children with pneumonia whose vaccination status was documented as not UTD had higher adjusted odds of receiving CRP level testing and influenza testing (P < .001). Children with croup whose vaccination status was documented as not UTD had higher adjusted odds of receiving blood cultures (P < .001). CONCLUSIONS: Children with ARTI whose vaccination status was documented as not UTD had higher odds of undergoing laboratory testing compared with children whose vaccination status was documented as UTD.

Accuracy of Provider-Documented Child Immunization Status at Hospital Presentation for Acute Respiratory Illness.

OBJECTIVES: 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 provider-documented 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.

Content and accuracy of vaccine information on pediatrician blogs.

BACKGROUND: Parents often use social media such as blogs to inform decisions about vaccinations, however little is known about pediatrician blogs addressing vaccines. The objective of this study was to assess content, citations, audience engagement and accuracy of vaccine information on pediatrician blogs. STUDY DESIGN: We conducted a content analysis of vaccine information on pediatrician blogs. A national sample of pediatrician blogs was identified using a search rubric of terms applied to multiple search engines. Inclusion criteria were: (1) the writer identified as a pediatrician (2) US based (3) ≥1 post since 1/1/2014. We identified 84 blogs; 56 fit inclusion criteria. Data were collected on all posts mentioning vaccines from 1/1/14 to 2/28/15. We identified the major topic for each post, examined citations to determine sources of information and counted the number of comments per post to evaluate audience engagement. We assessed accuracy of vaccine information using evaluation criteria adapted from information for parents on the CDC website. RESULTS: We identified 324 unique blog posts containing information about vaccines on 31 pediatrician blogs. The most common major topic was vaccine-specific posts (36%); Influenza and MMR were the most prevalent. Other common topics included: activism against anti-vaccine information (21%), vaccine exemptions (10%), autism (8%), and vaccine safety (6%). Activism against anti-vaccine information was the topic with the most reader engagement. The most common sources cited were governmental organizations such as the CDC and WHO (34%), and medical journals (31%). All blogs except 2 included information that was consistent with CDC information. CONCLUSIONS: Pediatrician bloggers frequently address vaccinations; most provide accurate information. Pediatrician blogs may be a new source to provide vaccine education to parents via social media.

Association of Bronchiolitis Clinical Pathway Adherence With Length of Stay and Costs.

OBJECTIVES: To examine the associations between the level of adherence to bronchiolitis clinical pathway recommendations, health care use, and costs. METHODS: We conducted a retrospective cohort study of 267 patients ≤24 months old diagnosed with bronchiolitis from 12/2009 to 7/2012. Clinical pathway adherence was assessed by using a standardized scoring system (0-100) for 18 quality measures obtained by medical record review. Level of adherence was categorized into low, middle, and high tertiles. Generalized linear models were used to examine relationships between adherence tertile and (1) length of stay (LOS) and (2) costs. Logistic regression was used to examine the associations between adherence tertile and probability of inpatient admission and 7-day readmissions. RESULTS: Mean adherence scores were: ED, 78.8 (SD, 18.1; n = 264), inpatient, 95.0 (SD, 6.3; n = 216), and combined ED/inpatient, 89.1 (SD, 8.1; n = 213). LOS was significantly shorter for cases in the highest versus the lowest adherence tertile (ED, 90 vs 140 minutes, adjusted difference, -51 [95% confidence interval (CI), -73 to -29; P <.05]; inpatient, 3.1 vs 3.8 days, adjusted difference, -0.7 [95% CI, -1.4 to 0.0; P <.05]). Costs were less for cases in the highest adherence tertile (ED, -$84, [95% CI, -$7 to -$161; P <.05], total, -$1296 [95% CI, -126.43 to -2466.03; P <.05]). ED cases in the highest tertile had a lower odds of admission (odds ratio, 0.38 [95% CI, 0.15-0.97; P < .05]). Readmissions did not differ by tertile. CONCLUSIONS: High adherence to bronchiolitis clinical pathway recommendations across care settings was associated with shorter LOS and lower cost.

Sports- and Recreation-Related Concussions in US Youth.

OBJECTIVE: 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.
