ABSTRACT
BACKGROUND: Most U.S. acute gastroenteritis (AGE) episodes in children are attributed to norovirus, whereas very little information is available on adenovirus 40/41 (AdV40/41), astrovirus or sapovirus. The New Vaccine Surveillance Network (NVSN) conducted prospective, active, population-based AGE surveillance in young children. METHODS: We tested and typed stool specimens collected between December 2011 to June 2016 from one NVSN site in Kansas City for the three viruses, and calculated hospitalization and emergency department (ED) detection rate. RESULTS: Of 3,205 collected specimens, 2,453 (76.5%) were from AGE patients (339 inpatients and 2,114 ED patients) and 752 (23.5%) were from healthy controls (HC). In AGE patients, astrovirus was detected in 94 (3.8%), sapovirus in 252 (10.3%) and AdV40/41 in 101 (4.5%) of 2249 patients. In HC, astrovirus was detected in 13 (1.7%) and sapovirus in 15 (2.0%) specimens. Astrovirus type 1 (37.7%) and genogroup I sapoviruses (59.3%) were most prevalent.Hospitalization rates were 5 (AdV40/41), 4 (astrovirus) and 8 (sapovirus) per 100,000 children <11 years old, whereas ED rates were 2.4 (AdV40/41), 1.9 (astrovirus) and 5.3 (sapovirus) per 1000 children <5 years old. CONCLUSIONS: Overall, AdV40/41, astrovirus, and sapovirus were detected in 18.6% of AGE in a large pediatric hospital in Kansas City.
ABSTRACT
OBJECTIVE: To describe demographics, pathogen distribution/seasonality, and risk factors in children seeking care for acute gastroenteritis (AGE) at a midwestern US emergency department during 5 postrotavirus vaccine years (2011-2016), and further, to compare the same data with matched healthy controls (HC). STUDY DESIGN: AGE and HC participants <11 years old enrolled in the New Vaccine Surveillance Network study between December 2011 to June 2016 were included. AGE was defined as ≥3 diarrhea episodes or ≥1 vomiting episode. Each HC's age was similar to an AGE participant's age. Pathogens were analyzed for seasonality effects. Participant risk factors for AGE illness and pathogen detections were compared between HC and a matched subset of AGE cases. RESULTS: One or more organisms was detected in 1159 of 2503 children (46.3%) with AGE compared with 99 of 537 HC (17.3%). Norovirus was detected most frequently among AGE (n = 568 [22.7%]) and second-most frequently in HC (n = 39 [6.8%]). Rotavirus was the second most frequently detected pathogen among AGE (n = 196 [7.8%]). Children with AGE were significantly more likely to have reported a sick contact compared with HC, both outside the home (15.6% vs 1.4%; P < .001) and inside the home (18.6% vs 2.1%; P < .001). Daycare attendance was higher among children with AGE (41.4%) compared with HC (29.5%; P < .001). The Clostridium difficile detection rate was slightly higher among HC (7.0%) than AGE (5.3%). CONCLUSIONS: Norovirus was the most prevalent pathogen among children with AGE. Norovirus was detected in some HC, suggesting potential asymptomatic shedding among HC. The proportion of AGE participants with a sick contact was approximately 10 times greater than that of HC.

BACKGROUND: Children with acute respiratory tract infections (ARTIs) receive ≈11.4 million unnecessary antibiotic prescriptions annually. A noted contributor is inadequate parent-clinician communication, however, efforts to reduce overprescribing have only indirectly targeted communication or been impractical. OBJECTIVES: Compare two feasible (higher vs lower intensity) interventions for enhancing parent-clinician communication on the rate of inappropriate antibiotic prescribing. DESIGN: Multisite, parallel group, cluster randomised comparative effectiveness trial. Data collected between March 2017 and March 2019. SETTING: Academic and private practice outpatient clinics. PARTICIPANTS: Clinicians (n=41, 85% of eligible approached) and 1599 parent-child dyads (ages 1-5 years with ARTI symptoms, 71% of eligible approached). INTERVENTIONS: All clinicians received 20 min ARTI diagnosis and treatment education. Higher intensity clinicians received an additional 50 min communication skills training. All parents viewed a 90 second antibiotic education video. MAIN OUTCOMES AND MEASURES: Inappropriate antibiotic treatment was assessed via blinded medical record review by study clinicians and a priori defined as prescriptions for the wrong diagnosis or use of the wrong agent. Secondary outcomes were revisits, adverse drug reactions (both assessed 2 weeks after the visit) and parent ratings of provider communication, shared decision-making and visit satisfaction (assessed at end of the visit on Likert-type scales). RESULTS: Most clinicians completed the study (n=38, 93%), were doctors (n=25, 66%), female (n=30, 78%) and averaged 8 years in practice. All parent-child dyad provided data for the main outcome (n=855 (54%) male, n=1043 (53%) <2 years). Inappropriate antibiotic prescribing was similar among patients who consulted with a higher intensity (54/696, 7.8%) versus a lower intensity (85/904, 9.4%) clinician. A generalised linear mixed effect regression model (adjusted for the two-stage nested design, clinician type, clinic setting and clinician experience) revealed that the odds of receiving inappropriate antibiotic treatment did not significantly vary by group (AOR 0.99, 95% CI: 0.52 to 1.89, p=0.98). Secondary outcomes of revisits and adverse reactions did not vary between arms, and parent ratings of satisfaction with quality of parent-provider communication (5/5), shared decision making (9/10) and visit satisfaction (5/5) were similarly high in both arms. CONCLUSIONS AND RELEVANCE: Rate of inappropriate prescribing was low in both arms. Clinician education coupled with parent education may be sufficient to yield low inappropriate antibiotic prescribing rates. The absence of a significant difference between groups indicates that communication principles previously thought to drive inappropriate prescribing may need to be re-examined or may not have as much of an impact in practices where prescribing has improved in recent years.

OBJECTIVES: To assess the impact of a 90-second animated video on parents' interest in receiving an antibiotic for their child. STUDY DESIGN: This pre-post test study enrolled English and Spanish speaking parents (n = 1051) of children ages 1-5 years presenting with acute respiratory tract infection symptoms. Before meeting with their provider, parents rated their interest in receiving an antibiotic for their child, answered 6 true/false antibiotic knowledge questions, viewed the video, and then rated their antibiotic interest again. Parents rated their interest in receiving an antibiotic using a visual analogue scale ranging from 0 to 100, with 0 being "I definitely do not want an antibiotic," 50 "Neutral," and 100 "I absolutely want an antibiotic." RESULTS: Parents were 84% female, with a mean age of 32 ± 6.0, 26.0% had a high school education or less, 15% were black, and 19% were Hispanic. After watching the video, parents' average antibiotic interest ratings decreased by 10 points (mean, 57.0 ± 20 to M ± 21; P < .0001). Among parents with the highest initial antibiotic interest ratings (≥60), even greater decreases were observed (83.0 ± 12.0 to 63.4 ± 22; P < .0001) with more than one-half (52%) rating their interest in the low or neutral ranges after watching the video. CONCLUSIONS: A 90-second video can decrease parents' interest in receiving antibiotics, especially among those with higher baseline interest. This scalable intervention could be used in a variety of settings to reduce parents' interest in receiving antibiotics. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03037112.

INTRODUCTION: Children with acute respiratory tract infections (ARTIs) are prescribed up to 11.4 million unnecessary antibiotic prescriptions annually. Inadequate parent-provider communication is a chief contributor, yet efforts to reduce overprescribing have only indirectly targeted communication or been impractical. This paper describes our multisite, parallel group, cluster randomised trial comparing two feasible interventions for enhancing parent-provider communication on the rate of inappropriate antibiotic prescribing (primary outcome) and revisits, adverse drug reactions and parent-rated quality of shared decision-making, parent-provider communication and visit satisfaction (secondary outcomes). METHODS/ANALYSIS: We will attempt to recruit all eligible paediatricians and nurse practitioners (currently 47) at an academic children's hospital and a private practice. Using a 1:1 randomisation, providers will be assigned to a higher intensity education and communication skills or lower intensity education-only intervention and trained accordingly. We will recruit 1600 eligible parent-child dyads. Parents of children ages 1-5 years who present with ARTI symptoms will be managed by providers trained in either the higher or lower intensity intervention. Before their consultation, all parents will complete a baseline survey and view a 90 s gain-framed antibiotic educational video. Parent-child dyads consulting with providers trained in the higher intensity intervention will, in addition, receive a gain-framed antibiotic educational brochure promoting cautious use of antibiotics and rate their interest in receiving an antibiotic which will be shared with their provider before the visit. All parents will complete a postconsultation survey and a 2-week follow-up phone survey. Due to the two-stage nested design (parents nested within providers and clinics), we will employ generalised linear mixed-effect regression models. ETHICS/DISSEMINATION: Ethical approval was obtained from the Children's Mercy Hospital Pediatric Institutional Review Board (#16060466). Results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03037112; Pre-results.
