RESUMEN
BACKGROUND: While Streptococcus pneumoniae (Spn) is the leading cause of pediatric complicated community acquired pneumonia (cCAP), it is infrequently recovered by culture-based methods. We studied the real-world clinical impact of an Spn PCR assay for pleural fluid. METHODS: This pre-post quasi-experimental cohort study compared pathogen detection, antibiotic usage, and outcomes in children hospitalized with cCAP requiring pleural effusion or empyema drainage at Children's Hospital Colorado between 2016 and 2023. Patients were compared across two diagnostic periods: pre-Spn PCR and post-Spn PCR. Cox proportional hazard models compared time from admission to pathogen detection, optimal therapy (narrowest pathogen-directed or guideline-recommended empiric therapy), and MRSA therapy discontinuation between periods. RESULTS: Compared to the pre-Spn PCR cohort (N=149), the post-Spn PCR cohort (N=79) was more likely to have a pathogen detected (73.4% post-PCR vs. 38.9% pre-PCR, p < 0.001), driven by more Spn detections (45.6% vs. 14.1%, p < 0.001). Time to pathogen detection during hospitalization was shorter in the post-Spn PCR period (p < 0.001). The post-PCR cohort was more likely to receive optimal therapy (84.8% vs. 53.0%, p < 0.001), with shorter median times to optimal antibiotics (4.9 vs. 10.0 days, p < 0.001) and MRSA therapy discontinuation (1.5 vs. 2.5 days, p = 0.03). There were no differences in hospital length of stay or readmissions. CONCLUSIONS: Spn molecular testing of pleural fluid in children with cCAP resulted in significantly more microbiologic diagnoses and was associated with the optimization of antibiotics and decreased exposure to MRSA therapy, suggesting its clinical impact for pediatric complicated pneumonia.
RESUMEN
Surveillance for emerging pathogens is critical for developing early warning systems to guide preparedness efforts for future outbreaks of associated disease. To better define the epidemiology and burden of associated respiratory disease and acute flaccid myelitis (AFM), as well as to provide actionable data for public health interventions, we developed a multimodal surveillance program in Colorado, USA, for enterovirus D68 (EV-D68). Timely local, state, and national public health outreach was possible because prospective syndromic surveillance for AFM and asthma-like respiratory illness, prospective clinical laboratory surveillance for EV-D68 among children hospitalized with respiratory illness, and retrospective wastewater surveillance led to early detection of the 2022 outbreak of EV-D68 among Colorado children. The lessons learned from developing the individual layers of this multimodal surveillance program and how they complemented and informed the other layers of surveillance for EV-D68 and AFM could be applied to other emerging pathogens and their associated diseases.

BACKGROUND: Children's Hospital Colorado created a unique method of antimicrobial stewardship, called handshake stewardship, that effectively decreased hospital anti-infective use and costs in its pilot year (2013). Handshake stewardship is distinguished by: (1) the lack of prior authorization; (2) a review of all prescribed anti-infectives; (3) a shared review by the physician and the pharmacist; and (4) a daily, rounding-based, in-person approach to supporting providers. We sought to reevaluate the outcomes of the program after 5 years of experience, totaling 8 years of data. METHODS: We retrospectively measured anti-infective (antibiotic, antiviral, antifungal) use hospital-wide by unit and by drug for an 8-year period spanning October 2010 to October 2018. Aggregated monthly use was measured in days of therapy per thousand patient days (DOT/1000 PD). The percentage of children admitted ever receiving an anti-infective was also measured, as well as severity-adjusted mortality, readmissions, and lengths of stay. RESULTS: Hospital-wide mean anti-infective use significantly decreased, from 891 (95% confidence interval [CI] 859-923) in the pre-implementation phase to 655 (95% CI 637-694) DOT/1000 PD in post-implementation Year 5; in a segmented regression time series analysis, this was a rate of -2.6 DOT/1000 PD (95% CI -4.8 to -0.4). This is largely attributable to decreased antibacterial use, from 704 (95% CI 686-722) to 544 (95% CI 525 -562) DOT/1000 PD. The percentage of children ever receiving an anti-infective during admission likewise declined, from 65% to 52% (95% CI 49-54). There were no detrimental effects on severity adjusted mortality, readmissions, or lengths of stay. CONCLUSIONS: The handshake method is an effective and sustainable approach to stewardship.

OBJECTIVES: To evaluate whether the implementation of a multiplex gastrointestinal pathogen panel (GIP) was associated with changes in Clostridioides difficile (C difficile) testing and detection rates. STUDY DESIGN: We conducted an observational study using interrupted time series analysis and included pediatric patients with testing capable of detecting C difficile. From 2013 to 2015 ("conventional diagnostic era"), stool testing included C difficile-selective polymerase chain reaction and other pathogen-specific tests. From 2015 to 2017 ("GIP era"), C difficile polymerase chain reaction was available along with the GIP, which detected 22 pathogens including C difficile, and replaced the need for additional tests. Outcomes included C difficile testing and detection rates in ambulatory, emergency department, and inpatient settings. RESULTS: There were 6841 tests performed and 1214 C difficile positive results. Across the 3 settings, GIP era had significantly higher C difficile testing (1.7-2.3 times higher) and C difficile detection rates (1.9-3.4 times higher) compared with conventional diagnostic era. After adjusting for the number of tests performed, detection rates were no longer significantly different. Of C difficile positive GIPs, 31% were coinfected with another organism. With GIP testing, patients 1 year of age had a significantly higher C difficile percent positivity than 2-year-old (P = .02) and 3- to 18-year-old children (P < .01). Younger children with C difficile were more likely to be coinfected (P < .01). CONCLUSIONS: Introducing a multiplex panel led to increased C difficile testing, which resulted in increased C difficile detection rates and potential identification and treatment of colonized patients. This highlights an important target for diagnostic stewardship and the challenges associated with multiplex testing.

OBJECTIVE: Acute kidney injury (AKI) is a common occurrence among hospitalized children and leads to increased mortality and prolonged length of stay (LOS) in critically ill patients. Few studies have examined the impact of AKI on LOS for common pediatric conditions. We hypothesized that a diagnosis of AKI would be associated with a longer hospital LOS and increased exposure to nephrotoxic medications for all patients. PATIENTS AND METHODS: We performed a multicenter retrospective cross-sectional analysis of 34 children's hospitals in the Pediatric Health Information System (PHIS) database from 1/2009 through 12/2013. Patients were grouped based on primary discharge diagnosis, number of days spent in an intensive care unit, and assignment of a secondary diagnostic code for AKI. Median LOS was compared among different patient groupings. Exposure to commonly used nephrotoxic medications was collected for each admission. RESULTS: A total of 588,884 admissions from 423,337 patients were included in the analysis. The median LOS among non-critically ill patients with and without AKI was 5 days [95% CI 3-10] versus 2 days [95% CI 1-4], respectively. Among critically ill patients, median LOS for those with and without AKI was 12 days [95% CI 7-20] versus 4 days [95% CI 2-7], respectively. Patients who developed AKI were more likely to have significant nephrotoxic exposure. CONCLUSIONS: Development of AKI was associated with longer hospital length of stay and increased nephrotoxic medication exposure for all diagnostic categories. Non-critically ill children with AKI were hospitalized the same length or longer than critically ill children without AKI.

BACKGROUND AND OBJECTIVES: The introduction of multiplex gastrointestinal panels at our institution resulted in increased Clostridioides difficile (C. difficile) detection and stool test utilization. We aimed to reduce hospital-onset C. difficile infections (HO-CDIs), C. difficile detection, and overall stool testing by 20% within 1 year. METHODS: We conducted a quality improvement project from 2018 to 2020 at a large children's hospital. Interventions included development of a C. difficile testing and treatment clinical care pathway, new options for gastrointestinal panel testing with or without C. difficile (results were suppressed if not ordered), clinical decision support tool to restrict testing, and targeted prevention efforts. Outcomes included the rate of HO-CDI (primary), C. difficile detection, and overall stool testing. All measures were evaluated monthly among hospitalized children per 10 000 patient-days (PDs) using statistical process-control charts. For balancing measures, we tracked suppressed C. difficile results that were released during real-time monitoring because of concern for true infection and C. difficile-related adverse events. RESULTS: HO-CDI decreased by 55%, from 11 to 5 per 10 000 PDs. C. difficile detection decreased by 44%, from 18 to 10 per 10 000 PDs, and overall test utilization decreased by 29%, from 99 to 70 per 10 000 PDs. The decrease in stool tests resulted in annual savings of $55 649. Only 2.3% of initially suppressed positive C. difficile results were released, and no patients had adverse events. CONCLUSIONS: Diagnostic stewardship strategies, coupled with an evidence-based clinical care pathway, can be used to decrease C. difficile and improve overall test utilization.

OBJECTIVES: There is uncertainty regarding which hospitalized patients with acute gastroenteritis (AGE) benefit from gastrointestinal panel (GIP) testing. Unnecessary testing may lead to increased costs, overdiagnosis, and overtreatment. In general, AGE management and outcomes are most impacted if an actionable (bacterial or parasitic) result is obtained. We aimed to assess which clinical reasons for ordering GIP testing ("order indications") and patient factors were associated with actionable results. METHODS: This is a cross-sectional study of pediatric patients hospitalized between 2015 and 2018 at a large pediatric health care system with diarrhea and a GIP performed. Multivariable regression analysis was used to determine associations between actionable GIP results and order indication, stool frequency, and demographics. Findings were evaluated in patients with complex chronic conditions (CCC) and non-CCC patients. RESULTS: There were 1124 GIPs performed in 967 encounters. Non-CCC patients had more actionable results than CCC patients, and reasons for testing differed. Across both cohorts, age ≥1 year old was positively associated with actionable results. For non-CCC patients, actionable results were associated with "diarrhea with blood or pus" order indication and nonwinter season; international travel was associated with non-Clostridioides difficile bacteria and parasites. No order indications were associated with actionable results for CCC patients. CONCLUSIONS: Patient factors and order indications that may help identify children hospitalized for AGE with actionable GIP results include older age (regardless of CCC status), as well as bloody stools and international travel in previously healthy children. Prospective validation of these findings could help improve diagnostic stewardship and decrease unnecessary testing.

BACKGROUND: In the fall of 2022, we observed a sharp rise in pediatric Invasive Group A Streptococcus (iGAS) hospitalizations in Colorado. We compared the epidemiology, clinical features, and patient outcomes in this outbreak to prior years. METHODS: Between October 2022 and April 2023, we prospectively identified and reviewed iGAS cases in hospitalized pediatric patients at Children's Hospital Colorado. Using laboratory specimen records, we also retrospectively compared the number of patients with sterile site GAS-positive cultures across three time periods: pre-COVID-19 (January 2015-March 2020), height of COVID-19 pandemic (April 2020-September 2022), and outbreak (October 2022-April 2023). RESULTS: Among 96 prospectively identified iGAS cases, median age was 5.7 years old; 66% were male, 70% previously healthy, 39% required critical care, and four patients died. Almost 60% had associated respiratory viral symptoms, 10% had toxic shock syndrome, and 4% had necrotizing fasciitis. Leukopenia, bandemia, and higher C-reactive protein values were laboratory findings associated with need for critical care. There were significantly more cases during the outbreak (9.9/month outbreak vs 3.9/month pre-pandemic vs 1.3/month pandemic), including more cases with pneumonia (28% outbreak vs 15% pre-pandemic vs 0% pandemic) and multifocal disease (17% outbreak vs 3% pre-pandemic vs 0% pandemic), Pâ <â .001 for all. CONCLUSIONS: Outbreak case numbers were almost triple the pre-pandemic baseline. The high percentage of cases with associated viral symptoms suggests a link to coinciding surges in respiratory viruses during this time. Invasive GAS can be severe and evolve rapidly; clinical and laboratory features may help in earlier identification of critically ill children.

BACKGROUND AND OBJECTIVES: Acute hematogenous musculoskeletal infections (MSKI) are medical emergencies with the potential for life-altering complications in afflicted children. Leveraging administrative data to study pediatric MSKI is difficult as many infections are chronic, nonhematogenous, or occur in children with significant comorbidities. The objective of this study was to validate a case-finding algorithm to accurately identify children hospitalized with acute hematogenous MSKI using administrative billing codes. METHODS: This was a multicenter validation study using the Pediatric Health Information System (PHIS) database. Hospital admissions for MSKI were identified from 6 PHIS hospitals using discharge diagnosis codes. A random subset of admissions underwent manual chart review at each site using predefined criteria to categorize each admission as either "acute hematogenous MSKI" (AH-MSKI) or "not acute hematogenous MSKI." Ten unique coding algorithms were developed using billing data. The sensitivity and specificity of each algorithm to identify AH-MSKI were calculated using chart review categorizations as the reference standard. RESULTS: Of the 492 admissions randomly selected for manual review, 244 (49.6%) were classified as AH-MSKI and 248 (50.4%) as not acute hematogenous MSKI. Individual algorithm performance varied widely (sensitivity 31% to 91%; specificity 52% to 98%). Four algorithms demonstrated potential for future use with receiver operating characteristic area under the curve greater than 80%. CONCLUSIONS: Identifying children with acute hematogenous MSKI based on discharge diagnosis alone is challenging as half have chronic or nonhematogenous infections. We validated several case-finding algorithms using administrative billing codes and detail them here for future use in pediatric MSKI outcomes.

Importance: Endotracheal aspirate cultures are commonly collected from patients with mechanical ventilation to evaluate for ventilator-associated pneumonia or tracheitis. However, the respiratory tract is not sterile, making differentiating between colonization from bacterial infection challenging, and results may be unreliable owing to variable specimen quality and sample processing across laboratories. Despite these limitations, clinicians routinely interpret bacterial growth in endotracheal aspirate cultures as evidence of infection, sometimes regardless of organism significance, prompting antibiotic treatment. Objective: To assess the variability in endotracheal aspirate culture rates and the association between culture rates and antibiotic prescribing among patients with mechanical ventilation across children's hospitals in the US. Design, Setting, and Participants: Cross-sectional retrospective analysis of data obtained from the Children's Hospital Association Pediatric Health Information System database between January 1, 2016, through December 31, 2019. Participants were all patients hospitalized with mechanical ventilation aged less than 18 years. Exposures: A charge for an endotracheal aspirate culture on a ventilated day. Main Outcomes and Measures: Endotracheal aspirate culture rate and antibiotic days of therapy per ventilated days. For mechanical ventilation, clinical transaction classification codes for mechanical ventilation other unspecified ventilator assistance were used. To identify respiratory cultures, the laboratory test code for aerobic culture was used and relevant keywords (ie, respiratory tract, sputum) were used to identify sources in the hospital charge description master. Results: A total of 152â¯132 patients were identified among 31 hospitals. Among these patients, 79â¯691 endotracheal aspirate cultures were collected on a ventilator-day (patients aged less than 1 year, 44%; 1-4 years, 27%, 5-11 years. 16%, and 12-18 years, 13%; 3% were Asian; 17% Hispanic; 21% non-Hispanic Black; 45% Non-Hispanic White patients; 14% were other; 56% of patients were male, 44% were female). The overall median rate of culture use was 46 per 1000 ventilator-days (IQR, 32-73 cultures per 1000 ventilator-days). The endotracheal aspirate culture rate was positively correlated with the hospital's antibiotic days of therapy rate (R = 0.46; P = .009). In a multivariable model adjusting for patient-level and hospital-level characteristics and among patients with mechanical ventilation, each additional endotracheal aspirate culture was associated with 2.87 (95% CI, 2.74-3.01) higher odds of receiving additional days of therapy compared with patients who did not receive and endotracheal aspirate culture. Conclusions and Relevance: In this study, notable variability was found in endotracheal aspirate culture rates across US pediatric hospitals and pediatric intensive care units, and endotracheal aspirate culture use was associated with increased antibiotic use. These findings suggest an opportunity for diagnostic and antibiotic stewardship to standardize testing and treatment of suspected ventilator-associated infections in pediatric patients with mechanical ventilation pediatric patients.

OBJECTIVES: Many hospitals have transitioned from conventional stool diagnostics to rapid multiplex polymerase chain reaction gastrointestinal panels (GIP). The clinical impact of this testing has not been evaluated in children. In this study, we compare use, results, and patient outcomes between conventional diagnostics and GIP testing. METHODS: This is a multicenter cross-sectional study of children who underwent stool testing from 2013 to 2017. We used bivariate analyses to compare test use, results, and patient outcomes, including length of stay (LOS), ancillary testing, and hospital charges, between the GIP era (24 months after GIP introduction) and conventional diagnostic era (historic control, 24 months before). RESULTS: There were 12 222 tests performed in 8720 encounters. In the GIP era, there was a 21% increase in the proportion of children who underwent stool testing, with a statistically higher percentage of positive results (40% vs 11%), decreased time to result (4 vs 31 hours), and decreased time to treatment (11 vs 35 hours). Although there was a decrease in LOS by 2 days among those who received treatment of a bacterial and/or parasitic pathogen (5.1 vs 3.1; P < .001), this represented only 3% of tested children. In the overall population, there was no statistical difference in LOS, ancillary testing, or charges. CONCLUSIONS: The GIP led to increased pathogen detection and faster results. This translated into improved outcomes for only a small subset of patients, suggesting that unrestricted GIP use leads to low-value care. Similar to other novel rapid diagnostic panels, there is a critical need for diagnostic stewardship to optimize GIP testing.

OBJECTIVE: To evaluate variations in treatment practice and compliance with national guidelines for the diagnostic evaluation of children with Kawasaki disease (KD). STUDY DESIGN: We used the Pediatric Hospital Information System database to analyze demographic, laboratory and treatment data from patients admitted with KD between January 1, 2006, and December 31, 2015. RESULTS: During the study period, 12,089 children with KD were diagnosed. Nearly all patients had a complete blood cell count, erythrocyte sedimentation rate, and C-reactive protein ordered. Fewer patients had alanine aminotransferase (48.6%) or a urinalysis (75.3%). A small percentage of children had abdominal imaging (11.5%), neck imaging (5.9%), and lumbar punctures (4.5%), and 36.0% of patients received antibiotic therapy. Obtaining echocardiograms pretreatment and the use of steroids and infliximab significantly increased over the study period (P < 0.001). For patients who failed initial intravenous immunoglobulin (IVIG) monotherapy, 82.0% received a second dose of IVIG, 7.7% received steroids, 6.5% received infliximab, and 3.9% received combination therapy. Patients receiving infliximab or steroids as second therapy had a higher response rate than those who received only a second IVIG dose (87.9% versus 83.0% versus 73.3%, P < 0.001). CONCLUSIONS: KD remains a challenging diagnosis. Opportunities exist for earlier use of echocardiograms in the evaluation of children with potential KD. Significant variations in practice exist surrounding second-line therapy. Our data suggest superiority of second-line therapy use of infliximab or steroids over IVIG in terms of reducing need for additional therapies. Prospective, controlled studies are needed to confirm this finding.

INTRODUCTION: It is important for clinicians to recognize the contribution of toxic shock syndrome (TSS) to the overall burden of pediatric septic shock because the clinical features, optimal therapy and prognosis differ from non-TSS septic shock. METHODS: We analyzed cases of pediatric septic shock reported to the Pediatric Health Information Systems database between 2009 and 2013 to define the clinical and demographic characteristics of pediatric TSS in the United States. Using a validated International Classification of Diseases, 9th revision, coding strategy, we identified patients with infectious shock among inpatients age 1-18 years and classified cases of staphylococcal and streptococcal TSS for comparison with non-TSS cases. RESULTS: Of 8,226 cases of pediatric septic shock, 909 (11.1%) were classified as TSS and 562 (6.8%) were possible TSS cases. Staphylococcal TSS represented the majority (83%) of TSS cases and occurred more commonly in females and at an older age. Compared with non-TSS septic shock, TSS had significantly lower fatality rates, disease severity and length of hospital stay and was present more often at the time of admission (P < 0.001 for each). Streptococcal TSS was associated with poorer outcomes than staphylococcal TSS. Treatment for TSS differed from non-TSS septic shock in use of more clindamycin, vancomycin and Intravenous Immunoglobulin and less need for vasopressors. CONCLUSIONS: Results demonstrate a significant contribution of TSS to the burden of pediatric septic shock in the United States. The findings emphasize the importance of inclusion of TSS diagnostic and therapeutic considerations in sepsis treatment protocols for children.

BACKGROUND AND OBJECTIVES: Croup is a clinical diagnosis, and the available evidence suggests that, except in rare cases, ancillary testing, such as radiologic imaging, is not helpful. Given the paucity of inpatient-specific evidence for croup care, we hypothesized that there would be marked variability in the use of not routinely indicated resources (NRIRs). Our primary study objective was to describe the variation and predictors of variation in the use of NRIRs. METHODS: This was a retrospective cohort study that used the Pediatric Health Information System database of generally healthy inpatients with croup aged 6 months to 15 years who were admitted between January 1, 2012 and September 30, 2014. We measured variability in the use of NRIRs: chest and lateral neck radiographs, viral testing, parenteral steroids, and antibiotics. Risk-adjusted analysis was used to compare resource utilization adjusted for hospital-specific effects and average case mix. RESULTS: The cohort included 26 hospitals and 6236 patients with a median age of 18 months. Nine percent of patients required intensive care services, and 3% had a 30-day readmission for croup. We found marked variability in adjusted and unadjusted utilization across hospitals for all resources. In the risk-adjusted analysis, hospital-specific effects rather than patient characteristics were the main predictor of variability in the use of NRIRs. CONCLUSIONS: We observed an up to fivefold difference in NRIR utilization attributable to hospital-level practice variability in inpatient croup care. This study highlights a need for inpatient-specific evidence and quality-improvement interventions to reduce unnecessary utilization and to improve patient outcomes.

The Pediatric Health Information System (PHIS) database collects admission, diagnostic, and treatment data among 44 children's hospitals across the United States (U.S.) and presents an opportunity for travel-associated infectious disease (TAID) surveillance. We calculated cumulative incidence rates among children admitted to 16 PHIS hospitals for dengue, malaria, and typhoid, and pooled TAID using discharge codes from 1999 to 2012. We compared incidence rates before, during, and after the 2007-2009 economic recession. Among 16 PHIS hospitals during the study period (1999-2012), incidence of dengue and pooled TAID (malaria, dengue, typhoid fever) increased significantly, and rates of malaria and typhoid trended upward. Admissions for dengue and pooled TAIDs increased significantly among 16 children's hospitals across the United States from 1999 to 2012. The PHIS database may provide a useful surveillance tool for TAIDs among children in the United States.

BACKGROUND: Diagnostic strategies based on empirical testing and treatment to identify herpes simplex virus (HSV) infection in neonates may not be appropriate for older children in whom the most common presentation of severe infection is encephalitis, a rare and clinically recognizable condition. METHODS: Use of acyclovir in infants and children in 6 common non-HSV infection-related diagnosis-related groups was characterized between 1999 and 2012 at 15 US pediatric hospitals by using the Pediatric Health Information System database. Characteristics of non-neonatal patients at 1 institution tested for HSV encephalitis over a 6.5-year period were then analyzed to identify factors associated with potentially unnecessary testing and treatment. RESULTS: Acyclovir use increased from 7.6% to 15.6% (P < .001) from 1999 to 2012. Much of this increase came in infants 30 to 60 days of age (82.7% increase, P < .001) and in patients with milder disease severity (44.8% increase, P < .001). Length of stay was increased by 2 days for children treated with acyclovir (P < .001). At our institution, 1394 HSV cerebrospinal fluid polymerase chain reactions were performed in children >30 days old, with only 3 positive results (0.22%). Comparison of the 3 subjects with positive testing and 55 with negative testing revealed that all cases, but only 4% (95% confidence interval 1.2%-14.0%) of noncases had clinical characteristics typical of HSV encephalitis. CONCLUSIONS: Strategies for diagnosis and empirical treatment of suspected HSV encephalitis beyond the neonatal period have trended toward the approach common for neonates without evidence of an increase in disease incidence. This may result in increased medical costs and risk to patients.
