RESUMEN
BACKGROUND: Incomplete uptake of guidelines can lead to nonstandardized care, increased expenditures, and adverse clinical outcomes. The objective of this study was to evaluate the impact of the 2011 Pediatric Infectious Diseases Society and Infectious Diseases Society of America (PIDS/IDSA) pediatric community-acquired pneumonia (CAP) guideline that emphasized aminopenicillin use and de-emphasized the use of chest radiographs (CXRs) in certain populations. METHODS: This quasi-experimental study queried a national administrative database of children's hospitals to identify children aged 3 months-18 years with CAP who visited 1 of 28 participating hospitals from 2009 to 2021. PIDS/IDSA pediatric CAP guideline recommendations regarding antibiotic therapy, diagnostic testing, and imaging were evaluated. Segmented regression interrupted time series was used to measure guideline-concordant practices with interruptions for guideline publication and the Coronavirus Disease 2019 (COVID-19) pandemic. RESULTS: Of 315 384 children with CAP, 71 804 (22.8%) were hospitalized. Among hospitalized children, there was a decrease in blood culture performance (0.5% per quarter) and increase in aminopenicillin prescribing (1.1% per quarter). Among children discharged from the emergency department (ED), there was an increase in aminopenicillin prescription (0.45% per quarter), whereas the rate of obtaining CXRs declined (0.12% per quarter). However, use of CXRs rebounded during the COVID-19 pandemic (increase of 1.56% per quarter). Hospital length of stay, ED revisit rates, and hospital readmission rates remained stable. CONCLUSIONS: Guideline publication was associated with an increase of aminopenicillin prescribing. However, rates of diagnostic testing did not materially change, suggesting the need to consider implementation strategies to meaningfully change clinical practice for children with CAP.

OBJECTIVES: To describe antibiotic prescribing patterns in ambulatory children with community-acquired pneumonia and to assess the relationship between antibiotic selection and clinical outcomes. STUDY DESIGN: This was a retrospective cohort study of ambulatory Medicaid-enrolled children 0-18 years of age diagnosed with community-acquired pneumonia from 2010 to 2016. The exposure was antibiotic class: narrow-spectrum (aminopenicillins), broad-spectrum (amoxicillin/clavulanate and cephalosporins), macrolide monotherapy, macrolides with narrow-spectrum antibiotics, or macrolides with broad-spectrum antibiotics. The associations between antibiotic selection and the outcomes of subsequent hospitalization and development of severe pneumonia (chest drainage procedure, intensive care admission, mechanical ventilation) were assessed, controlling for measures of illness severity. RESULTS: Among 252 177 outpatient pneumonia visits, macrolide monotherapy was used in 43.2%, narrow-spectrum antibiotics in 26.1%, and broad-spectrum antibiotics in 24.7%. A total of 1488 children (0.59%) were subsequently hospitalized and 117 (0.05%) developed severe pneumonia. Compared with children receiving narrow-spectrum antibiotics, the odds of subsequent hospitalization were higher in children receiving broad-spectrum antibiotics (aOR, 1.34; 95% CI, 1.17-1.52) and lower in children receiving macrolide monotherapy (aOR, 0.64; 95% CI, 0.55-0.73) and macrolides with narrow-spectrum antibiotics (aOR, 0.62; 95% CI, 0.39-0.97). Children receiving macrolide monotherapy had lower odds of developing severe pneumonia than children receiving narrow-spectrum antibiotics (aOR, 0.56; 95% CI, 0.33-0.93). However, the absolute risk difference was <0.5% for all analyses. CONCLUSIONS: Macrolides are the most commonly prescribed antibiotic for ambulatory children with community-acquired pneumonia. Subsequent hospitalization and severe pneumonia are rare. Future efforts should focus on reducing broad-spectrum and macrolide antibiotic prescribing.

OBJECTIVE: To identify practice patterns in the duration of prescribed antibiotics for the treatment of ambulatory children with community-acquired pneumonia (CAP) and to compare the frequency of adverse clinical outcomes between children prescribed short-vs prolonged-duration antibiotics. STUDY DESIGN: We performed a retrospective cohort study from 2010-2016 using the IBM Watson MarketScan Medicaid Database, a claims database of publicly insured patients from 11 states. We included children 1-18 years old with outpatient CAP who filled a prescription for oral antibiotics (n = 121 846 encounters). We used multivariable logistic regression to determine associations between the duration of prescribed antibiotics (5-9 days vs 10-14 days) and subsequent hospitalizations, new antibiotic prescriptions, and acute care visits. Outcomes were measured during the 14 days following the end of the dispensed antibiotic course. RESULTS: The most commonly prescribed duration of antibiotics was 10 days (82.8% of prescriptions), and 10.5% of patients received short-duration therapy. During the follow-up period, 0.2% of patients were hospitalized, 6.2% filled a new antibiotic prescription, and 5.1% had an acute care visit. Compared with the prolonged-duration group, the aORs for hospitalization, new antibiotic prescriptions, and acute care visits in the short-duration group were 1.16 (95% CI 0.80-1.66), 0.93 (95% CI 0.85-1.01), and 1.06 (95% CI 0.98-1.15), respectively. CONCLUSIONS: Most children treated for CAP as outpatients are prescribed at least 10 days of antibiotic therapy. Among pediatric outpatients with CAP, no significant differences were found in rates of adverse clinical outcomes between patients prescribed short-vs prolonged-duration antibiotics.

BACKGROUND: Fever is a common symptom in children presenting to the Emergency Department (ED). We aimed to describe the epidemiology of systemic viral infections and their predictive values for excluding serious bacterial infections (SBIs), including bacteremia, meningitis and urinary tract infections (UTIs) in children presenting to the ED with suspected systemic infections. METHODS: We enrolled children who presented to the ED with suspected systemic infections who had blood cultures obtained at seven healthcare facilities. Whole blood specimens were analyzed by an experimental multiplexed PCR test for 7 viruses. Demographic and laboratory results were abstracted. RESULTS: Of the 1114 subjects enrolled, 245 viruses were detected in 224 (20.1%) subjects. Bacteremia, meningitis and UTI frequency in viral bloodstream-positive patients was 1.3, 0 and 10.1% compared to 2.9, 1.3 and 9.7% in viral bloodstream-negative patients respectively. Although viral bloodstream detections had a high negative predictive value for bacteremia or meningitis (NPV = 98.7%), the frequency of UTIs among these subjects remained appreciable (9/89, 10.1%) (NPV = 89.9%). Screening urinalyses were positive for leukocyte esterase in 8/9 (88.9%) of these subjects, improving the ability to distinguish UTI. CONCLUSIONS: Viral bloodstream detections were common in children presenting to the ED with suspected systemic infections. Although overall frequencies of SBIs among subjects with and without viral bloodstream detections did not differ significantly, combining whole blood viral testing with urinalysis provided high NPV for excluding SBI.

Respiratory viral infections in infants undergoing congenital heart surgery lead to prolonged intubation time, hospital (HLOS) and cardiac intensive care unit length of stay (CICU LOS). The objective of this study was to evaluate the prevalence of respiratory viruses using molecular testing in otherwise healthy infants presenting for low complexity heart surgery, and to evaluate the impact of a positive viral screen and study questionnaire on post-surgical HLOS, CICU LOS, intubation time, respiratory complications, and oxygen therapy at home discharge. Sixty-nine infants (1 month to 1 year) undergoing cardiac surgery from November to May of the years 2012 to 2014 were prospectively enrolled, surveyed and tested. We compared the outcomes of positive molecular testing and positive study questionnaire to test negative subjects. We also evaluated the predictive value of study questionnaire in identification of viruses by molecular testing. Of the 69 enrolled infants, 58 had complete information available for analysis. 17 (30%) infants tested positive by molecular testing for respiratory pathogens. 38 (65%) had a "positive" questionnaire. Among the 20 viruses detected, Human Rhinovirus was the most common 12 (60%). Seven (12%) of the 58 patients developed respiratory symptoms following surgery prompting molecular testing. Four of these tested positive for a respiratory virus post-surgically. Neither positive molecular testing nor a positive questionnaire prior to surgery was associated with greater post-operative HLOS, CICU LOS, intubation time, respiratory complications, or use of oxygen at discharge compared to negative testing. The questionnaire poorly predicted positive molecular testing. Routine screening for respiratory viruses in asymptomatic infants may not be an effective strategy to predict infants at risk of post-operative complications.

In pediatric practice it is common for infants under 2 months of age to undergo evaluation for sepsis when they are ill, often including lumbar puncture to assess for central nervous system (CNS) infection. The FilmArray Meningitis/Encephalitis (ME) panel is a newly approved test for rapid identification of CNS pathogens. Our objective was to study the epidemiology of CNS infection in young infants and the potential impact of rapid multiplex PCR on their care. A performance evaluation of the FilmArray ME panel was conducted from February 2014 to September 2014 at 11 sites. FilmArray ME panel results were compared to reference standards but not shared with providers. In our study, medical records for infants (aged 1 to 60 days) enrolled at three sites were reviewed for clinical, laboratory, and outcome data. A total of 145 infants were reviewed. The median age was 25 days. Most of the infants were hospitalized (134/145 [92%]) and received antibiotics (123/145 [85%]), and almost half (71/145 [49%]) received acyclovir. One infant had a bacterial pathogen, likely false positive, identified by the FilmArray ME panel. Thirty-six infants (25%) had a viral pathogen detected, including 21 enteroviruses. All infants with enteroviral meningitis detected by the FilmArray ME panel and conventional PCR were hospitalized, but 20% were discharged in less than 24 h when conventional PCR results became available. The FilmArray ME panel may play a role in the evaluation of young infants for CNS infection. Results may be used to guide management, possibly resulting in a decreased length of stay and less antimicrobial exposure for infants with low-risk viral infection detected.

BACKGROUND: Recent trials suggest procalcitonin-based guidelines can reduce antibiotic use for respiratory infections. However, the accuracy of procalcitonin to discriminate between viral and bacterial pneumonia requires further dissection. METHODS: We evaluated the association between serum procalcitonin concentration at hospital admission with pathogens detected in a multicenter prospective surveillance study of adults hospitalized with community-acquired pneumonia. Systematic pathogen testing included cultures, serology, urine antigen tests, and molecular detection. Accuracy of procalcitonin to discriminate between viral and bacterial pathogens was calculated. RESULTS: Among 1735 patients, pathogens were identified in 645 (37%), including 169 (10%) with typical bacteria, 67 (4%) with atypical bacteria, and 409 (24%) with viruses only. Median procalcitonin concentration was lower with viral pathogens (0.09 ng/mL; interquartile range [IQR], <0.05-0.54 ng/mL) than atypical bacteria (0.20 ng/mL; IQR, <0.05-0.87 ng/mL; P = .05), and typical bacteria (2.5 ng/mL; IQR, 0.29-12.2 ng/mL; P < .01). Procalcitonin discriminated bacterial pathogens, including typical and atypical bacteria, from viral pathogens with an area under the receiver operating characteristic (ROC) curve of 0.73 (95% confidence interval [CI], .69-.77). A procalcitonin threshold of 0.1 ng/mL resulted in 80.9% (95% CI, 75.3%-85.7%) sensitivity and 51.6% (95% CI, 46.6%-56.5%) specificity for identification of any bacterial pathogen. Procalcitonin discriminated between typical bacteria and the combined group of viruses and atypical bacteria with an area under the ROC curve of 0.79 (95% CI, .75-.82). CONCLUSIONS: No procalcitonin threshold perfectly discriminated between viral and bacterial pathogens, but higher procalcitonin strongly correlated with increased probability of bacterial pathogens, particularly typical bacteria.

BACKGROUND: The Red Queen hypothesis is an evolutionary theory that describes the reciprocal coevolution of competing species. We sought to study whether introduction of the 7- and 13-valent pneumococcal conjugate vaccines (PCV7 and PCV13, respectively) altered pneumococcal serotype dynamics among children with invasive pneumococcal disease (IPD) as predicted by the Red Queen hypothesis. METHODS: This study examined pneumococcal isolates (n = 641) obtained from children <18 years of age hospitalized with IPD from 1997 to 2014 in Utah. A review of the literature also identified several additional studies conducted in the United States and Europe that were used to test the external generalizability of our Utah findings. Simpson's index was used to quantify pneumococcal serotype diversity. RESULTS: In Utah, the introduction of PCV7 and PCV13 was associated with rapid increases in serotype diversity (P < .001). Serotypes rarely present before vaccine introduction emerged as common causes of IPD. Diversity then decreased (P < .001) as competition selected for the fittest serotypes and new evolutionary equilibriums were established. This pattern was also observed more broadly in the United States, the United Kingdom, Norway, and Spain. CONCLUSIONS: This vaccine-driven example of human/bacterial coevolution appears to confirm the Red Queen hypothesis, which reveals a limitation of serotype-specific vaccines and offers insights that may facilitate alternative strategies for the elimination of IPD.

OBJECTIVE: To inform the decision to test and empirically treat for herpes simplex virus (HSV) by describing the initial clinical presentation and laboratory findings of infants with a confirmed diagnosis of neonatal HSV. STUDY DESIGN: This is a retrospective case series performed at 2 pediatric tertiary care centers. Infants who developed symptoms prior to 42 days of age with laboratory confirmed HSV from 2002 through 2012 were included. We excluded infants <34 weeks gestation, those who developed illness before discharge from their birth hospital, and those who developed symptoms after 42 days of age. RESULTS: We identified 49 infants with HSV meeting these criteria. Most infants (43/49, 88%) came to medical attention at ≤28 days. Of 49 infants, 22 (45%) had disseminated, 16 (33%) central nervous system, and 10 (20%) skin, eye, mouth HSV disease. Eight infants (16%) had nonspecific presentations without the classic signs of seizure, vesicular rash, or critical illness (intensive care admission). All infants with nonspecific presentation were ≤14 days, had cerebrospinal fluid pleocytosis, or both. CONCLUSIONS: The majority of infants with HSV (84%) presented with seizure, vesicular rash, or critical illness. A subset of patients (16%) lacked classic signs at hospitalization; most manifested signs suggestive of HSV within 24 hours. Further studies are needed to validate the risk factors identified in this study including age <14 days and cerebrospinal fluid pleocytosis at presentation.

BACKGROUND: This study: (1) describes the viral etiology of respiratory illness by prospectively collecting weekly symptom diaries and nasal swabs from families for 1 year, (2) analyzed data by reported symptoms, virus, age, and family composition, and (3) evaluated the duration of virus detection. METHODS: Twenty-six households (108 individuals) provided concurrent symptom and nasal swab data for 4166 person-weeks. The FilmArray polymerase chain reaction (PCR) platform (BioFire Diagnostics, LLC) was used to detect 16 respiratory viruses. Viral illnesses were defined as ≥1 consecutive weeks with the same virus detected with symptoms reported in ≥1 week. RESULTS: Participants reported symptoms in 23% and a virus was detected in 26% of person-weeks. Children younger than 5 years reported symptoms more often and were more likely to have a virus detected than older participants (odds ratio [OR] 2.47, 95% confidence interval [CI], 2.08-2.94 and OR 3.96, 95% CI, 3.35-4.70, respectively). Compared with single person households, individuals living with children experienced 3 additional weeks of virus detection. There were 783 viral detection episodes; 440 (56%) associated with symptoms. Coronaviruses, human metapneumovirus, and influenza A detections were usually symptomatic; bocavirus and rhinovirus detections were often asymptomatic. The mean duration of PCR detection was ≤2 weeks for all viruses and detections of ≥3 weeks occurred in 16% of episodes. Younger children had longer durations of PCR detection. CONCLUSIONS: Viral detection is often asymptomatic and occasionally prolonged, especially for bocavirus and rhinovirus. In clinical settings, the interpretation of positive PCR tests, particularly in young children and those who live with them, may be confounded.

BACKGROUND AND OBJECTIVES: Viral bronchiolitis is a common pediatric illness. Treatment is supportive; however, some children have concurrent serious bacterial infections (cSBIs) requiring antibiotics. Identifying children with cSBI is challenging and may lead to unnecessary treatment. Improved understanding of the prevalence of and risk factors for cSBI are needed to guide treatment. We sought to determine the prevalence of cSBI and identify factors associated with cSBI in children hospitalized with bronchiolitis. METHODS: We performed a retrospective cohort study of children <2 years old hospitalized with bronchiolitis at a free-standing children's hospital from 2012 to 2019 identified by International Classification of Diseases codes. cSBI was defined as bacteremia, urinary tract infection, meningitis, or pneumonia. Risk factors for cSBI were identified using logistic regression. RESULTS: We identified 7871 admissions for bronchiolitis. At least 1 cSBI occurred in 4.2% of these admissions; with 3.5% meeting our bacterial pneumonia definition, 0.4% bacteremia, 0.3% urinary tract infection, and 0.02% meningitis. cSBI were more likely to occur in children with invasive mechanical ventilation (odds ratio [OR] 2.53, 95% confidence interval [CI] 1.78-3.63), a C-reactive protein ≥4 mg/dL (OR 2.20, 95% CI 1.47-3.32), a concurrent complex chronic condition (OR 1.67, 95% CI 1.22-2.25) or admission to the PICU (OR 1.46, 95% CI 1.02-2.07). CONCLUSIONS: cSBI is uncommon among children hospitalized with bronchiolitis, with pneumonia being the most common cSBI. Invasive mechanical ventilation, elevated C-reactive protein, presence of complex chronic conditions, and PICU admission were associated with an increased risk of cSBI.

BACKGROUND: Emerging evidence suggests that initial oral and intravenous (IV) antibiotics have similar efficacy in pediatric community-acquired pneumonia (CAP), but further data are needed. OBJECTIVE: We determined the association between hospital-level initial oral antibiotic rates and outcomes in pediatric CAP. DESIGNS, SETTINGS, AND PARTICIPANTS: This retrospective cohort study included children hospitalized with CAP at 43 hospitals in the Pediatric Health Information System (2016-2022). Hospitals were grouped by whether initial antibiotics were given orally in a high, moderate, or low proportion of patients. MAIN OUTCOME AND MEASURES: Regression models examined associations between high versus low oral-utilizing hospitals and length of stay (LOS, primary outcome), intensive care unit (ICU) transfers, escalated respiratory care, complicated CAP, cost, readmissions, and emergency department (ED) revisits. RESULTS: Initial oral antibiotics were used in 16% (interquartile range: 10%-20%) of 30,207 encounters, ranging from 1% to 68% across hospitals. Comparing high versus low oral-utilizing hospitals (oral rate: 32% [27%-47%] and 10% [9%-11%], respectively), there were no differences in LOS, intensive care unit, complicated CAP, cost, or ED revisits. Escalated respiratory care occurred in 1.3% and 0.5% of high and low oral-utilizing hospitals, respectively (relative ratio [RR]: 2.96 [1.12, 7.81]), and readmissions occurred in 1.5% and 0.8% (RR: 1.68 [1.31, 2.17]). Initial oral antibiotics varied across hospitals without a difference in LOS. While high oral-utilizing hospitals had higher escalated respiratory care and readmission rates, these were rare, the clinical significance of these small differences is uncertain, and there were no differences in other clinically relevant outcomes. This suggests some children may benefit from initial IV antibiotics, but most would probably do well with oral antibiotics.

BACKGROUND: Limited data exist to inform antibiotic selection among people with cystic fibrosis (CF) with airway infection by multiple CF-related microorganisms. This study aimed to determine among children with CF co-infected with methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (Pa) if the addition of anti-MRSA antibiotics to antipseudomonal antibiotic treatment for pulmonary exacerbations (PEx) would be associated with improved clinical outcomes compared with antipseudomonal antibiotics alone. METHODS: Retrospective cohort study using data from the CF Foundation Patient Registry-Pediatric Health Information System linked dataset. The odds of returning to baseline lung function and having a subsequent PEx requiring intravenous antibiotics were compared between PEx treated with anti-MRSA and antipseudomonal antibiotics and those treated with antipseudomonal antibiotics alone, adjusting for confounding by indication using inverse probability of treatment weighting. RESULTS: 943 children with CF co-infected with MRSA and Pa contributed 2,989 PEx for analysis. Of these, 2,331 (78%) PEx were treated with both anti-MRSA and antipseudomonal antibiotics and 658 (22%) PEx were treated with antipseudomonal antibiotics alone. Compared with PEx treated with antipseudomonal antibiotics alone, the addition of anti-MRSA antibiotics to antipseudomonal antibiotic therapy was not associated with a higher odds of returning to ≥90% or ≥100% of baseline lung function or a lower odds of future PEx requiring intravenous antibiotics. CONCLUSIONS: Children with CF co-infected with MRSA and Pa may not benefit from the addition of anti-MRSA antibiotics for PEx treatment. Prospective studies evaluating optimal antibiotic selection strategies for PEx treatment are needed to optimize clinical outcomes following PEx treatment.

BACKGROUND: Invasive group A Streptococcus (GAS) infections are associated with substantial morbidity and mortality. Recent national surveillance data report stable rates of invasive GAS disease, although these may not capture geographic variation. METHODS: We performed a population-based, retrospective laboratory surveillance study of invasive GAS disease among Utah residents from 2002-2010. We used Intermountain Healthcare's electronic medical records and data warehouse to identify patients from whom GAS was isolated by culture. We defined clinical syndromes of invasive GAS disease on the basis of International Classification of Diseases, Ninth Revision codes. We abstracted demographic information, comorbidities, and microbiologic and laboratory findings. RESULTS: From 2002-2010, we identified 1514 cases of invasive GAS disease among Utah residents. The estimated mean annual incidence rate was 6.3 cases/100,000 persons, which was higher than the national rate of 3.6 cases/100,000 (P < .01). The incidence of invasive GAS disease in Utah rose from 3.5 cases/100,000 persons in 2002 to 9.8 cases/100,000 persons in 2010 (P = .01). Among children aged <18 years, the incidence of invasive GAS increased from 3.0 cases/100,000 children in 2002 to 14.1 cases/100,000 children in 2010 (P < .01). The increase in the pediatric population was due, in part, to an increase in GAS pneumonia (P = .047). The rate of invasive GAS disease in adults aged 18-64 years increased from 3.4 cases/100 000 persons in 2002 to 7.6 cases/100,000 persons in 2010 (P = .02). Rates among those aged ≥65 years were stable. The incidence of acute rheumatic fever declined from 6.1 to 3.7 cases/100,000 (P = .04). CONCLUSIONS: The epidemiologic characteristics of invasive GAS disease in Utah has changed substantially over the past decade, including a significant increase in the overall incidence of invasive disease-driven primarily by increasing disease in younger persons-that coincided temporally with a decrease in the incidence of acute rheumatic fever.

BACKGROUND: Despite the increased availability of diagnostic tests for respiratory viruses, their clinical utility for children with community-acquired pneumonia (CAP) remains uncertain. OBJECTIVE: To identify patterns of respiratory virus testing across children's hospitals prior to the COVID-19 pandemic and to determine whether hospital-level rates of viral testing were associated with clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS: Multicenter retrospective cohort study of children hospitalized for CAP at 19 children's hospitals in the United States from 2010-2019. MAIN OUTCOMES AND MEASURES: Using a novel method to identify the performance of viral testing, we assessed time trends in the use of viral tests, both overall and stratified by testing method. Adjusted proportions of encounters with viral testing were compared across hospitals and were correlated with length of stay, antibiotic and oseltamivir use, and performance of ancillary laboratory testing. RESULTS: There were 46,038 hospitalizations for non-severe CAP among children without complex chronic conditions. The proportion with viral testing increased from 38.8% to 44.2% during the study period (p < .001). Molecular testing increased (27.2% to 40.0%, p < .001) and antigen testing decreased (33.2% to 7.8%, p < .001). Hospital-specific adjusted proportions of testing ranged from 10.0% to 83.5% and were not associated with length of stay, antibiotic use, or antiviral use. Hospitals that performed more viral testing did not have lower rates of ancillary laboratory testing. CONCLUSIONS: Viral testing practices varied widely across children's hospitals and were not associated with clinically important process or outcome measures. Viral testing may not influence clinical management for many children hospitalized with CAP.

Streptococcus pneumoniae is both an aggressive pathogen and a normal part of the human respiratory microbiome. Clinicians and microbiologists have struggled to develop tests that can identify pneumococcal respiratory infection and accurately distinguish colonization from invasive disease. Molecular methods hold the promise of an improved ability to rapidly detect microorganisms in respiratory secretions and to make an accurate diagnosis; however, interpretation of diagnostic testing for S. pneumoniae remains problematic. Molecular assays, such as those targeting the pneumolysin gene, may cross-react with other streptococcal species, confounding detection and quantification. Assays that target the autolysin gene appear to be more specific. Even when accurately identified, however, the significance of S. pneumoniae DNA detected in clinical samples is difficult to determine. Here we will discuss the challenges faced in the interpretation of molecular testing for S. pneumoniae, and some strategies that might be used to improve our ability to diagnose pneumococcal respiratory infection.

OBJECTIVES: To describe testing and treatment practices for Mycoplasma pneumoniae (Mp) among children hospitalized with community-acquired pneumonia (CAP). METHODS: We conducted a retrospective cohort study using the Pediatric Health Information Systems database. We included children 3 months to 18 years old hospitalized with CAP between 2012 and 2018 and excluded children who were transferred from another hospital and those with complex chronic conditions. We examined the proportion of patients receiving Mp testing and macrolide therapy at the hospital level and trends in Mp testing and macrolide prescription over time. At the patient level, we examined differences in demographics, illness severity (eg, blood gas, chest tube placement), and outcomes (eg, ICU admission, length of stay, readmission) among patients with and without Mp testing. RESULTS: Among 103 977 children hospitalized with CAP, 17.3% underwent Mp testing and 31.1% received macrolides. We found no correlation between Mp testing and macrolide treatment at the hospital level (R 2 = 0.05; P = .11). Patients tested for Mp were more likely to have blood gas analysis (15.8% vs 12.8%; P < .1), chest tube placement (1.4% vs 0.8%; P < .1), and ICU admission (3.1% vs 1.4%; P < .1). Mp testing increased (from 15.8% to 18.6%; P < .001), and macrolide prescription decreased (from 40.9% to 20.6%; P < .001) between 2012 and 2018. CONCLUSIONS: Nearly one-third of hospitalized children with CAP received macrolide antibiotics, although macrolide prescription decreased over time. Clinicians were more likely to perform Mp testing in children with severe illness, and Mp testing and macrolide treatment were not correlated at the hospital level.
