For children hospitalized with SSSS, lower use of diagnostic tests was not associated with changes in outcomes. Hospitals with high diagnostic test use may be able to reduce testing without adversely affecting patient outcomes.

A B S T R A C TOBJECTIVES: To describe variation in empirical antibiotic selection in infants ,60 days old who are hospitalized with skin and soft-tissue infections (SSTIs) and to determine associations with outcomes, including length of stay (LOS), 30-day returns (emergency department revisit or readmission), and standardized cost. METHODS:Using the Pediatric Health Information System, we conducted a retrospective study of infants hospitalized with SSTI from 2009 to 2014. We analyzed empirical antibiotic selection in the first 2 days of hospitalization and categorized antibiotics as those typically administered for (1) staphylococcal infection, (2) neonatal sepsis, or (3) combination therapy (staphylococcal infection and neonatal sepsis). We examined the association of antibiotic selection and outcomes using generalized linear mixed-effects models. RESULTS:A total of 1319 infants across 36 hospitals were included; the median age was 30 days (interquartile range [IQR]: 17-42 days). We observed substantial variation in empirical antibiotic choice, with 134 unique combinations observed before categorization. The most frequently used antibiotics included staphylococcal therapy (50.0% [IQR: 39.2-58.1]) and combination therapy (45.4% [IQR: 36.0-56.0]). Returns occurred in 9.2% of infants. Compared with administration of staphylococcal antibiotics, use of combination therapy was associated with increased LOS (adjusted rate ratio: 1.35; 95% confidence interval: 1.17-1.53) and cost (adjusted rate ratio: 1.39; 95% confidence interval: 1.21-1.58), but not with 30-day returns.CONCLUSIONS: Infants who are hospitalized with SSTI experience wide variation in empirical antibiotic selection. Combination therapy was associated with increased LOS and cost, with no difference in returns. Our findings reveal the need to identify treatment strategies that can be used to optimize resource use for infants with SSTI.

OBJECTIVES: Children with asthma are at increased risk of complications from influenza; hospitalization represents an important opportunity for vaccination. We aimed to increase the influenza vaccination rate among eligible hospitalized patients with asthma on the pediatric hospital medicine (PHM) service from 13% to 80% over a 4-year period.METHODS: Serial Plan-Do-Study-Act cycles were implemented to improve influenza vaccination rates among children admitted with status asthmaticus and included modifications to the electronic health record (EHR) and provider and family education. Success of the initial PHM pilot led to the development of a hospital-wide vaccination tracking tool and an institutional, nurse-driven vaccine protocol by a multidisciplinary team. Our primary outcome metric was the inpatient influenza vaccination rate among PHM patients admitted with status asthmaticus. Process measures included documentation of influenza vaccination status and use of the EHR asthma order set and a history and physical template. The balance measure was adverse vaccine reaction within 24 hours. Data analysis was performed by using statistical process control charts. RESULTS:The inpatient influenza vaccination rate increased from 13% to 57% over 4 years; special cause variation was achieved. Overall, 50% of eligible patients were vaccinated during asthma hospitalization in the postintervention period. Documentation of influenza vaccination status significantly increased from 51% to 96%, and asthma history and physical and order set use also improved. No adverse vaccine reactions were documented.CONCLUSIONS: A bundle of interventions, including EHR modifications, provider and family education, hospital-wide tracking, and a nurse-driven vaccine protocol, increased influenza vaccination rates among eligible children hospitalized with status asthmaticus.
