The safety and immunogenicity of an orally administered, live rotavirus vaccine comprised of four strains, each with a titer of 10(5.3) or 10(5.8) pfu, and each having 10 genes from the UK bovine strain and the VP7 gene from human rotavirus serotype 1, 2, 3, or 4, were evaluated in adults, young children and infants in randomized, double-blind phase 1 trials. Three doses of rotavirus vaccine or placebo given with childhood immunizations to infants at 2, 4, and 6 months of age were well tolerated and did not inhibit antibody responses to childhood vaccines which included DTP, Hib, hepatitis B and OPV. Serum rotavirus antibody responses were detected in 12 of 20 infants after 1 dose, and in 19/19 of the vaccinees after three doses. Neutralizing antibody responses were detected more often against the bovine rotavirus UK strain (95%) than to human rotavirus VP7 serotypes 1 (37%), 2 (32%), 3 (32%) or 4 (32%). The efficacy of this quadrivalent rotavirus vaccine needs to be evaluated further.

OBJECTIVE The aim of this study was to determine if an information sheet containing photographs and explanations of the training level of medical providers could enhance a parents ability to identify their childs providers and whether this would impact parental attitudes toward trainee involvement and patient satisfaction. METHODS This was a prospective, mixed methods study of parent-child dyads admitted to an academic general pediatric inpatient service. The intervention group received a photo information sheet (Photographs of Academic Clinicians and Their Educational Status [PHACES] tool) consisting of passport-sized photos of the medical team along with information regarding their training. Parents were asked to name their childs providers, were surveyed about their attitudes toward trainees, participated in a brief, semistructured interview and completed the patient satisfaction questionnaire (ABIM-PSQ). RESULTS Comparing intervention with control parents, 40 of 49 (82%) versus 19 of 51 (37%) were able to name at least one provider (adjusted odds ratio 8.0; P < .01). Parents who received the intervention were more likely to correctly match the face with the name of the medical student (67% vs 14%; P < .01) and attending (80% vs 24%; P < .01). Parents who received the intervention were more likely to report acceptance of the involvement of medical students and house staff as well as an improved understanding of their roles. Parents who received the intervention scored higher on the ABIM-PSQ (mean 48.3 vs 45.4; P = .008). CONCLUSIONS An information sheet containing the photographs of health care providers along with an explanation of their training improves recognition of the health care team members, improves acceptance of trainee involvement, and improves satisfaction with care delivered by physicians in training.

Importance The quality of pediatric resuscitative care delivered across the spectrum of emergency departments (EDs) in the United States is poorly described. In a recent study, more than 4000 EDs completed the Pediatric Readiness Survey (PRS); however, the correlation of PRS scores with the quality of simulated or real patient care has not been described. Objective To measure and compare the quality of resuscitative care delivered to simulated pediatric patients across a spectrum of EDs and to examine the correlation of PRS scores with quality measures. Design, Setting, and Participants This prospective multicenter cohort study evaluated 58 interprofessional teams in their native pediatric or general ED resuscitation bays caring for a series of 3 simulated critically ill patients (sepsis, seizure, and cardiac arrest). Main Outcomes and Measures A composite quality score (CQS) was measured as the sum of 4 domains: (1) adherence to sepsis guidelines, (2) adherence to cardiac arrest guidelines, (3) performance on seizure resuscitation, and (4) teamwork. Pediatric Readiness Survey scores and health care professional demographics were collected as independent data. Correlations were explored between CQS and individual domain scores with PRS. Results Overall, 58 teams from 30 hospitals participated (8 pediatric EDs [PEDs], 22 general EDs [GEDs]). The mean CQS was 71 (95% CI, 68-75); PEDs had a higher mean CQS (82; 95% CI, 79-85) vs GEDs (66; 95% CI, 63-69) and outperformed GEDs in all domains. However, when using generalized estimating equations to estimate CQS controlling for clustering of the data, PED status did not explain a higher CQS (β = 4.28; 95% CI, -4.58 to 13.13) while the log of pediatric patient volume did explain a higher CQS (β = 9.57; 95% CI, 2.64-16.49). The correlation of CQS to PRS was moderate (r = 0.51; P < .001). The correlation was weak for cardiac arrest (r = 0.24; P = .07), weak for sepsis (ρ = 0.45; P < .001) and seizure (ρ = 0.43; P = .001), and strong for teamwork (ρ = 0.71; P < .001). Conclusions and Relevance This multicenter study noted significant differences in the quality of simulated pediatric resuscitative care across a spectrum of EDs. The CQS was higher in PEDs compared with GEDs. However, when controlling for pediatric patient volume and other variables in a multivariable model, PED status does not explain a higher CQS while pediatric patient volume does. The correlation of the PRS was moderate for simulation-based measures of quality.

Background Overall usage of email communication between patients and physicians continues to increase, due in part to expanding the adoption of electronic health records and patient portals. Unequal access and acceptance of these technologies has the potential to exacerbate disparities in care. Little is known about the attitudes of pediatric caregivers with regard to their acceptance of email as a means to communicate with their health care providers. Objective We conducted a survey to assess pediatric caregiver access to and attitudes toward the use of electronic communication modalities to communicate with health care providers in an urban pediatric primary care clinic. Methods Participants were pediatric caregivers recruited from an urban pediatric primary care clinic in Baltimore, Maryland, who completed a 35-item questionnaire in this cross-sectional study. Results Of the 229 caregivers who completed the survey (91.2% response rate), 171 (74.6%) reported that they use email to communicate with others. Of the email users, 145 respondents (86.3%) stated that they would like to email doctors, although only 18 (10.7%) actually do so. Among email users, African-American caregivers were much less likely to support the expanded use of email communication with health care providers (adjusted OR 0.34, 95% CI 0.14-0.82) as were those with annual incomes less than US

30,000 (adjusted OR 0.26, 95% CI 0.09-0.74). Conclusions Caregivers of children have access to email and many would be interested in communicating with health care providers. However, African-Americans and those in lower socioeconomic groups were much less likely to have positive attitudes toward email.

OBJECTIVES Obesity is the most common chronic disease of childhood. Although it is accepted that diet and exercise practices are important, there is little data to discern the contributions of specific activities toward a healthy body weight. We sought to identify associations between bicycling and overweight status and to compare this with other physical activities and dietary practices thought to be protective against overweight status. METHODS We constructed a survey to gather dietary and activity practices in a cross-sectional, convenience sample of 100 children presenting to an urban hospital setting in Baltimore, Maryland. We chose to emphasize bicycling because it is a widely available activity that requires a sustained level of moderate energy expenditure, yet little is known about the relationship of this particular activity with childhood overweight status. RESULTS The mean age of our population was 11.8 years and 56% were overweight (body mass index>85 percentile). Most (96%) knew how to ride a bike and 80% reported owning a bike. Children who rode a bike just once a week or less were the most likely to be overweight (multivariate-adjusted odds ratio 6.6, 95% confidence interval, 2.1-21). This association was stronger than for all other dietary and activity practices. We found that approximately half of our participants do not eat breakfast, fruits, or vegetables regularly. More than half never ride a bike to school, walk to school, or participate in any organized sport. CONCLUSIONS Riding a bicycle at least 2 or more days during the week is associated with a decreased likelihood of being overweight during childhood.

Introduction Simulation-based education is expensive and requires greater resources than traditional methods, yet there is limited evidence to justify such expenditures for medical student education. Methods We describe the implementation and evaluation of a simulation-based curriculum delivered to medical students during a pediatric clerkship. This prospective mixed-methods study evaluated a 5-day long simulation-based clinical skills curriculum (PRE-Clerkship EDucational Exercises [PRECEDE]) at the Johns Hopkins University School of Medicine. Two hundred medical students participated in PRECEDE during a 2-year period and were compared with 236 students who had not. Outcomes were assessed across 3 levels of Kirkpatrick’s framework for evaluation. The 4-level model consists of reaction, learning, behavior, and results criteria. Secondary outcomes measured changes in assessment scores across 16 student performance domains during clerkship, changes in performance on the National Board of Medical Examiners subject examination in pediatrics, and student assessments of the curriculum. Results Improvements were noted across 3 levels of the Kirkpatrick’s model. Student performance evaluations were significantly higher across all 16 evaluation components, with effect sizes ranging from small to medium (Cohen’s d, 0.23–0.44). Students scored significantly higher on the National Board of Medical Examiners pediatric shelf examination (80 vs. 77, P < 0.001). Ninety-seven percent of the medical students agreed that their skills increased and that the time lost to real clinical experiences was a worthwhile trade-off for this curriculum Conclusions The implementation of a simulation-based curriculum within a pediatrics clerkship resulted in higher knowledge scores and led to improvements in medical student clinical performance during the clerkship.

OBJECTIVE Follow-up of pediatric patients after an emergency department (ED) visit is important for monitoring changes in patient health and informing patients of test results conducted during the visit. The telephone has been the standard method of communication, but contact rates are poor. We conducted a survey to assess pediatric caregiver attitudes toward and access to alternate electronic communication modalities after a pediatric ED encounter. SUBJECTS AND METHODS Participants (n=102) were recruited from an urban community ED and completed a 35-item questionnaire in this cross-sectional study. RESULTS The majority of pediatric caregivers have Internet access in their home (72%), although less than half check e-mail daily (46%). A larger percentage owns a cell phone (90%) and checks text messages daily (87%). The majority agree that more doctors should communicate by e-mail (70%), and nearly half (45%) would like to receive test results by text message. CONCLUSIONS Caregivers of children have access to the Internet and mobile phone technologies, and many would be interested in communicating with healthcare providers following an ED visit. Cell phone and text-messaging technologies appear to be more available than e-mail and may serve as an underutilized contact method. A combination of modalities directed by caregiver preferences may improve ED follow-up contact rates.

OBJECTIVE To document the prevalence of simulation-based education (SBE) for third- and fourth-year medical students; to determine the perceived importance of SBE; to characterize the barriers associated with establishing SBE. METHODS A 27-item survey regarding simulation was distributed to members of the Council on Medical Student Education in Pediatrics (COMSEP) as part of a larger survey in 2012. RESULTS Seventy-one (48%) of 147 clerkship directors (CD) at COMSEP institutions responded to the survey questions regarding the use of SBE. Eighty-nine percent (63 of 71) of CDs reported use of SBE in some form: 27% of those programs (17 of 63) reported only the use of the online-based Computer-Assisted Learning in Pediatrics Program, and 73% (46 of 63) reported usage of other SBE modalities. Fifty-four percent of CDs (38 of 71) agreed that SBE is necessary to meet the requirements of the Liaison Committee on Medical Education (LCME). Multiple barriers were reported in initiating and implementing an SBE program. CONCLUSIONS SBE is commonly used for instruction during pediatric undergraduate medical education in North American medical schools. Barriers to the use of SBE remain despite the perception that it is needed to meet requirements of the LCME.

OBJECTIVE One of the greatest challenges for clerkship directors is assigning a final grade and determining the precise point at which a student either passes or fails a clinical clerkship. The process of incorporating both subjective and objective assessment data to provide a final summative grade can be challenging. We describe our experience conducting a standard-setting exercise to set defensible cut points in a 4-tiered grading system in our pediatric clerkship. METHODS Using the Hofstee standard-setting approach, 8 faculty members participated in an exercise to establish grade cut points. These faculty members were subsequently surveyed to assess their attitudes toward the standard-setting process as well as their reactions to these newly proposed standards. We applied the new cut points to a historic cohort of 116 Johns Hopkins University School of Medicine students from the academic year 2012-2013 to assess the potential impact on grade distributions. RESULTS The resultant grading schema would lead to a significant increase in the number of students receiving a failing grade and a decrease in the number of students receiving a grade of honors in a historical cohort. Faculty reported that the Hofstee method was easy to understand and fair. All faculty members thought that grade inflation presently exists within the pediatric clerkship. CONCLUSIONS This study demonstrates that practical standards using the Hofstee method can be set for medical students in a pediatric clerkship in which multiple performance measures are used.
