Abstract

<p><strong>BACKGROUND: </strong>Use of intravenous magnesium (IVMg) for childhood asthma exacerbations has increased significantly in the last decade. Emergency department administration of IVMg has been shown to reduce asthma hospitalization, yet most children receiving IVMg in the emergency department are subsequently hospitalized. Our objective with the study was to examine hospital outcomes of children given IVMg for asthma exacerbations.</p>

<p><strong>METHODS: </strong>We conducted a retrospective cohort study using data from the Pediatric Health Information System. We used propensity score matching to compare children who received IVMg on the first day of hospitalization with those who did not. Primary outcomes were initiation and duration of noninvasive positive pressure ventilation. Secondary outcomes included mechanical ventilation (MV) initiation, duration of MV, length of stay, and subsequent tertiary medication use. Primary analysis was restricted to children admitted to nonintensive care inpatient units.</p>

<p><strong>RESULTS: </strong>Overall, 91 309 hospitalizations met inclusion criteria. IVMg was administered in 25 882 (28.4%) children. After propensity score matching, IVMg was not significantly associated with lower initiation (adjusted odds ratio 0.88; 95% confidence interval [CI] 0.74-1.05) or shorter duration of noninvasive positive pressure ventilation (rate ratio 0.94; 95% CI 0.87-1.02). Similarly, no significant associations were seen for MV initiation, MV duration, or length of stay. IVMg was associated with lower subsequent tertiary medication use (adjusted odds ratio 0.66; 95% CI 0.60-0.72). However, the association was lost when ipratropium was removed from the tertiary medication definition.</p>

<p><strong>CONCLUSIONS: </strong>IVMg administration was not significantly associated with improved hospital outcomes. Further study is needed to inform the optimal indications and timing of magnesium use during hospitalization.</p>

Abstract

<p>Intravenous (IV) magnesium is used as an adjunct therapy in management of status asthmaticus with a goal of reducing intubation rate. A recent review suggests that IV magnesium use in status asthmaticus reduces admission rates. This is contrary to the observation of practicing emergency room physicians. The goal of this study was to assess trends in IV magnesium use for status asthmaticus in US children's hospitals over 8 years through a retrospective analysis of children younger than 18 years using the Pediatric Health Information System database. Outcomes were IV magnesium use, inpatient and intensive care unit admission rate, geometric mean length of stay, and 7-day all-cause readmission rate. IV magnesium use for asthma hospitalization more than doubled over 8 years (17% vs. 36%; P &lt; .001). Yearly trends were not significantly associated with hospital or intensive care unit admission rate or 7-day all-cause readmissions, although length of stay was reduced (P &lt; .001).</p>

Abstract

<p><strong>OBJECTIVES: </strong>To describe hospital-based asthma-specific discharge components at children's hospitals and determine the association of these discharge components with pediatric asthma readmission rates.</p>

<p><strong>STUDY DESIGN: </strong>This is a multicenter retrospective cohort study of pediatric asthma hospitalizations in 2015 at children's hospitals participating in the Pediatric Health Information System. Children ages 5 to 17 years were included. An electronic survey assessing 13 asthma-specific discharge components was sent to quality leaders at all 49 hospitals. Correlations of combinations of asthma-specific discharge components and adjusted readmission rates were calculated.</p>

<p><strong>RESULTS: </strong>The survey response rate was 92% (45 of 49 hospitals). Thirty-day and 3-month adjusted readmission rates varied across hospitals, ranging from 1.9% to 3.9% for 30-day readmissions and 5.7% to 9.1% for 3-month readmissions. No individual or combination discharge components were associated with lower 30-day adjusted readmission rates. The only single-component significantly associated with a lower rate of readmission at 3 months was having comprehensive content of education (P &lt; .029). Increasing intensity of discharge components in bundles was associated with reduced adjusted 3-month readmission rates, but this did not reach statistical significance. This was seen in a 2-discharge component bundle including content of education and communication with the primary medical doctor, as well as a 3-discharge component bundle, which included content of education, medications in-hand, and home-based environmental mitigation.</p>

<p><strong>CONCLUSIONS: </strong>Children's hospitals demonstrate a range of asthma-specific discharge components. Although we found no significant associations for specific hospital-level discharge components and asthma readmission rates at 30 days, certain combinations of discharge components may support hospitals to reduce healthcare utilization at 3 months.</p>

Abstract

<p><strong>BACKGROUND AND OBJECTIVES: </strong>National guidelines recommend blood cultures for children hospitalized with presumed bacterial community-acquired pneumonia (CAP) that is moderate or severe. We sought to determine the prevalence of bacteremia and characterize the microbiology and penicillin-susceptibility patterns of positive blood culture results among children hospitalized with CAP.</p>

<p><strong>METHODS: </strong>We conducted a cross-sectional study of children hospitalized with CAP in 6 children's hospitals from 2007 to 2011. We included children 3 months to 18 years of age with discharge diagnosis codes for CAP using a previously validated algorithm. We excluded children with complex chronic conditions. We reviewed microbiologic data and classified positive blood culture detections as pathogens or contaminants. Antibiotic-susceptibility patterns were assessed for all pathogens.</p>

<p><strong>RESULTS: </strong>A total of 7509 children hospitalized with CAP were included over the 5-year study period. Overall, 34% of the children hospitalized with CAP had a blood culture performed; 65 (2.5% of patients with blood cultures; 95% confidence interval [CI]: 2.0%-3.2%) grew a pathogen. Streptococcus pneumoniae accounted for 78% of all detected pathogens. Among detected pathogens, 50 (82%) were susceptible to penicillin. Eleven children demonstrated growth of an organism nonsusceptible to penicillin, representing 0.43% (95% CI: 0.23%-0.77%) of children with blood cultures obtained and 0.15% (95% CI: 0.08%-0.26%) of all children hospitalized with CAP.</p>

<p><strong>CONCLUSIONS: </strong>Among children without comorbidities hospitalized with CAP in a non-ICU setting, the rate of bacteremia was low, and isolated pathogens were usually susceptible to penicillin. Blood cultures may not be needed for most children hospitalized with CAP.</p>

Abstract

<p><strong>BACKGROUND: </strong>We evaluated the impact of the 2011 Pediatric Infectious Diseases Society/Infectious Diseases Society of America pneumonia guideline and hospital-level implementation efforts on antibiotic prescribing for children hospitalized with pneumonia.</p>

<p><strong>METHODS: </strong>We assessed inpatient antibiotic prescribing for pneumonia at 28 children's hospitals between August 2009 and March 2015. Each hospital was also surveyed regarding local implementation efforts targeting antibiotic prescribing and organizational readiness to adopt guideline recommendations. To estimate guideline impact, we used segmented linear regression to compare the proportion of children receiving penicillins in March 2015 with the expected proportion at this same time point had the guideline not been published based on a projection of a preguideline trend. A similar approach was used to estimate the short-term (6-month) impact of local implementation efforts. The correlations between organizational readiness and the impact of the guideline were estimated by using Pearson's correlation coefficient.</p>

<p><strong>RESULTS: </strong>Before guideline publication, penicillin prescribing was rare (&lt;10%). After publication, an absolute increase in penicillin use was observed (27.6% [95% confidence interval: 23.7%-31.5%]) by March 2015. Among hospitals with local implementation efforts (n = 20, 71%), the median increase was 29.5% (interquartile range: 19.6%-39.1%) compared with 20.1% (interquartile rage: 9.5%-44.5%) among hospitals without such activities (P = .51). The independent, short-term impact of local implementation efforts was similar in magnitude to that of the national guideline. Organizational readiness was not correlated with prescribing changes.</p>

<p><strong>CONCLUSIONS: </strong>The publication of the Pediatric Infectious Diseases Society/Infectious Diseases Society of America guideline was associated with sustained increases in the use of penicillins for children hospitalized with pneumonia. Local implementation efforts may have enhanced guideline adoption and appeared more relevant than hospitals' organizational readiness to change.</p>

Abstract

<p><strong>BACKGROUND: </strong>National guidelines for the management of community-acquired pneumonia (CAP) in children were published in 2011. These guidelines discourage most diagnostic testing for outpatients, as well as repeat testing for hospitalized patients who are improving. We sought to evaluate the temporal trends in diagnostic testing associated with guideline implementation among children with CAP.</p>

<p><strong>METHODS: </strong>Children 1 to 18 years old who were discharged with pneumonia after emergency department (ED) evaluation or hospitalization from January 1, 2008 to June 30, 2014 at any of 32 children's hospitals participating in the Pediatric Health Information System were included. We excluded children with complex chronic conditions and those requiring intensive care or who underwent early pleural drainage. We compared use of diagnostic testing (blood culture, complete blood count [CBC], C-reactive protein [CRP], and chest radiography [CXR]) before and after release of the guidelines, and assessed for temporal trends using interrupted time series analysis. We also calculated the cost impact of these changes on diagnostic utilization and evaluated the variability of the guideline's impact across hospitals.</p>

<p><strong>RESULTS: </strong>Overall, 220,539 patients were included; 53% were male and the median age was 4 years (interquartile range, 2-7). For patients discharged from the ED with CAP, diagnostic utilization rates for blood culture, CBC, CRP, and CXR were higher after guideline publication compared with expected utilization rates without guidelines. In contrast, initial testing and repeat testing among patients hospitalized with CAP was lower after guideline publication. There were modest reductions in estimated costs associated with these changes. However, wide variability was observed in the impact of the guidelines across hospitals.</p>

<p><strong>CONCLUSIONS: </strong>Publication of national pneumonia guidelines in 2011 was associated with modest changes in diagnostic testing for children with CAP. However, the changes varied across hospitals, and the financial impact was modest. Local implementation efforts are warranted to ensure widespread guideline adherence.

Abstract

<p><strong>BACKGROUND AND OBJECTIVES: </strong>Pneumonia is a leading cause of hospitalization and readmission in children. Understanding the patient characteristics associated with pneumonia readmissions is necessary to inform interventions to reduce avoidable hospitalizations and related costs. The objective of this study was to characterize readmission rates, and identify factors and costs associated with readmission among children previously hospitalized with pneumonia.</p>

<p><strong>METHODS: </strong>Retrospective cohort study of children hospitalized with pneumonia at the 43 hospitals included in the Pediatric Health Information System between January 1, 2008, and December 31, 2011. The primary outcome was all-cause readmission within 30 days after hospital discharge, and the secondary outcome was pneumonia-specific readmission. We used multivariable regression models to identify patient and hospital characteristics and costs associated with readmission.</p>

<p><strong>RESULTS: </strong>A total of 82 566 children were hospitalized with pneumonia (median age, 3 years; interquartile range 1-7). Thirty-day all-cause and pneumonia-specific readmission rates were 7.7% and 3.1%, respectively. Readmission rates were higher among children &lt;1 year of age, as well as in patients with previous hospitalizations, longer index hospitalizations, and complicated pneumonia. Children with chronic medical conditions were more likely to experience all-cause (odds ratio 3.0; 95% confidence interval 2.8-3.2) and pneumonia-specific readmission (odds ratio 1.8; 95% confidence interval 1.7-2.0) compared with children without chronic medical conditions. The median cost of a readmission ($11 344) was higher than that of an index admission ($4495; P = .01). Readmissions occurred in 8% of pneumonia hospitalizations but accounted for 16.3% of total costs for all pneumonia hospitalizations.</p>

<p><strong>CONCLUSIONS: </strong>Readmissions are common after hospitalization for pneumonia, especially among young children and those with chronic medical conditions, and are associated with substantial costs.</p>
