Background: Our objectives were to (1) characterize patient and clinical characteristics of adults hospitalized with meningitis; (2) describe meningitis hospitalization outcomes, including 30- and 90-day readmissions; and (3) determine whether clinical, patient, or index hospitalization characteristics are associated with readmission and readmission outcomes., Methods: This retrospective study of the 2014 National Readmissions Database extracted data on hospitalized adults with a principal diagnosis of meningitis and examined hospitalization outcomes using descriptive statistics. Logistic regression models were built to determine whether characteristics were associated with 30- or 90-day readmissions., Results: For the 30-day readmission analyses, 18,883 adults qualified. Meningitis hospitalizations commonly involved adults 25 to 54 years of age who were insured by private carriers. The readmission rates were 7.0% at 30 days and 11.4% at 90 days. Readmission was associated with greater comorbidity burden (2 conditions: adjusted odds ratio [AOR] = 1.60, range 1.24-2.08; 3 conditions: AOR = 1.92, range 1.43-2.58; 4+ conditions: AOR = 2.68, range 2.04-3.51 vs 0 or 1 condition), public insurance (Medicare: AOR = 1.85, range 1.30-2.62; Medicaid: AOR = 1.48, range 1.16-1.90 vs private insurance), and medical error (AOR = 1.43, range 1.07-1.91). Readmissions were most often for meningitis, septicemia, or medical complications., Conclusions: Readmission after hospitalization for meningitis is associated with both fixed and modifiable factors. More research is needed to determine which post-meningitis readmissions are preventable., (Copyright © 2019 Association for Professionals in Infection Control and Epidemiology, Inc.

Influenza is a significant cause of childhood morbidity and death; it contributes to up to 16% of hospitalizations for respiratory illnesses worldwide. Novel rapid viral diagnostic tests, including molecular diagnostic tests, have the potential to significantly affect both time to diagnosis and selection of optimal anti-infective therapy. However, little is known about current treatment algorithms used in US hospitals. In this study, for hospitalized children in the United States, we aimed to define the current approaches to influenza diagnosis and treatment and to explore reasons for their potential variation. In this study, we aimed to define the current approaches to pediatric influenza diagnosis and treatment in US hospitals, and to explore reasons for their potential variation. Our results suggest a rise in the availability and use of rapid molecular diagnostic testing in addition to continued variability in anti-infective management, particularly with regard to antiviral use., (© The Author(s) 2018.

Background: Antibiotics are the most common medicines prescribed to children in hospitals and the community, with a high proportion of potentially inappropriate use. Antibiotic misuse increases the risk of toxicity, raises healthcare costs, and selection of resistance. The primary aim of this systematic review is to summarize the current state of evidence of the implementation and outcomes of pediatric antimicrobial stewardship programs (ASPs) globally., Methods: MEDLINE, Embase and Cochrane Library databases were systematically searched to identify studies reporting on ASP in children aged 0-18 years and conducted in outpatient or in-hospital settings. Three investigators independently reviewed identified articles for inclusion and extracted relevant data., Results: Of the 41,916 studies screened, 113 were eligible for inclusion in this study. Most of the studies originated in the USA (52.2%), while a minority were conducted in Europe (24.7%) or Asia (17.7%). Seventy-four (65.5%) studies used a before-and-after design, and sixteen (14.1%) were randomized trials. The majority (81.4%) described in-hospital ASPs with half of interventions in mixed pediatric wards and ten (8.8%) in emergency departments. Only sixteen (14.1%) studies focused on the costs of ASPs. Almost all the studies (79.6%) showed a significant reduction in inappropriate prescriptions. Compliance after ASP implementation increased. Sixteen of the included studies quantified cost savings related to the intervention with most of the decreases due to lower rates of drug administration. Seven studies showed an increased susceptibility of the bacteria analysed with a decrease in extended spectrum beta-lactamase producers E. coli and K. pneumoniae; a reduction in the rate of P. aeruginosa carbapenem resistance subsequent to an observed reduction in the rate of antimicrobial days of therapy; and, in two studies set in outpatient setting, an increase in erythromycin-sensitive S. pyogenes following a reduction in the use of macrolides., Conclusions: Pediatric ASPs have a significant impact on the reduction of targeted and empiric antibiotic use, healthcare costs, and antimicrobial resistance in both inpatient and outpatient settings. Pediatric ASPs are now widely implemented in the USA, but considerable further adaptation is required to facilitate their uptake in Europe, Asia, Latin America and Africa., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s). 2019.)

Background: Systems for standardizing physician payment have been shown to undervalue cognitive clinical encounters. Because health care reform emphasizes value-based approaches, we need an understanding of the way pediatric cognitive specialties are used to contribute to the provision of high-value care. We sought to investigate how clinical and administrative stakeholders perceive the value of pediatric infectious disease (PID) specialists., Methods: We conducted qualitative interviews with a purposive sample of physicians and administrators from 5 hospitals across the United States in which children are cared for. All interviews were transcribed and systematically analyzed for common themes., Results: We interviewed 97 stakeholders. Analysis revealed the following 3 domains of value: clinical, organizational, and communicative. Clinically, PID specialists were perceived to be highly valuable in treating patients with unusual infections that respond poorly to therapy, in optimizing the use of antimicrobial agents and in serving as outpatient homes for complex patients. Respondents perceived that PID specialists facilitate communication with patients and their families, the health care team and the media. PID specialists were perceived to generate value by participating in systemwide activities, including antimicrobial stewardship and infection prevention. Despite this, much of the valuable work PID specialists perform is difficult to measure causing some administrative stakeholders to question how many PID specialists are necessary to achieve high-quality care., Conclusions: With our findings, we suggest that pediatric cognitive specialties contribute value in multiple ways to the health care delivery system. Many of these domains are difficult to capture by using current metrics, which may lead administrators to overlook valuable work and to under-allocate resources., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2018 by the American Academy of Pediatrics.)

Objectives: To study the trend of Clostridium difficile infection (CDI) and risk factors for hospital acquired CDI (HA-CDI) among children with cancer., Study Design: We analyzed 33 095 first pediatric hospitalizations for malignancy among 43 pediatric hospitals between 1999 and 2011. The effect of demographics, disease characteristics, and weekly drug exposure (antibiotics, antacids, and chemotherapy) on HA-CDI was assessed with multivariate Cox regression. CDI was defined by the combination of International Classification of Diseases, 9th edition-Clinical Modification (ICD-9CM), CDI diagnostic assay billing code, and concurrent administration of a CDI-active antibiotic. HA-CDI was defined as CDI with assay occurring after the sixth hospital day., Results: A total of 1736 admissions with CDI were identified, of which 380 were HA-CDI. CDI incidence increased from 1999-2006 (P = .01); however, CDI testing frequency and disease decreased from 2006-2010 (P < .05). Admissions with HA-CDI had longer lengths of stay compared with those without HA-CDI (35 days vs 12 days, P < .01) and greater risk of inpatient mortality (relative risk 2.3, P < .01). Increased risk of HA-CDI (hazard ratio [95% CI]) was seen after exposure to the following drugs: aminoglycoside (1.357 [1.053-1.749]), third generation cephalosporin (1.518 [1.177-1.959]), cefepime (2.383 [1.839-3.089]), and proton pump inhibiting agent (1.398 [1.096-1.784]) in the prior week, and chemotherapy (1.942 [1.491-2.529]) in the 8-14 days prior to HA-CDI onset. Histamine-2 receptor antagonist exposure in the prior week was associated with decreased risk of HA-CDI (0.730 [0.584-0.912])., Conclusions: Despite an apparent decrease in CDI incidence from 2006-2010, HA-CDI remains prevalent and morbid among children with cancer. Recent exposure to chemotherapy, proton pump inhibitor, and certain antibiotics were independent risk factors for HA-CDI., (Copyright © 2013 Mosby, Inc. All rights reserved.)

Objectives: The objective was to estimate the frequency of pregnancy testing among adolescent emergency department (ED) patients and to determine factors associated with testing., Methods: This was a retrospective cross-sectional study using the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2005 through 2009 of ED visits by females ages 14 to 21 years. The frequency of pregnancy testing among all visits was estimated for potential reproductive health complaints and for those associated with exposure to potentially teratogenic radiation. Multivariable logistic regression modeling was performed to calculate adjusted probabilities and odds ratios (ORs) with 95% confidence intervals (CIs) to evaluate factors associated with pregnancy testing by patient characteristics., Results: The authors identified 11,531 visits, representing an estimated 41.0 million female adolescent ED visits. Of these, 20.9% (95% CI = 19.3% to 22.5%) included pregnancy testing. Among visits for potential reproductive health complaints and those associated with exposure to potentially teratogenic radiation, 44.5% (95% CI = 41.3% to 47.8%) and 36.7% (95% CI = 32.5% to 40.9%), respectively, included pregnancy testing. Among the entire study population, we found statistically significant differences in pregnancy testing by age, race or ethnicity, hospital admission, and geographic region (p < 0.001 for all)., Conclusions: A minority of female adolescent ED visits included pregnancy testing, even if patients presented with potential reproductive health complaints or received exposure to ionizing radiation. Small but statistically significant differences in pregnancy testing rates were noted based on age, race or ethnicity, ED disposition, and geographic region. Future studies should focus on designing quality improvement interventions to increase pregnancy testing in adolescent ED patients, especially among those in whom pregnancy complications or the risk of potentially teratogenic radiation exposure is higher., (© 2013 by the Society for Academic Emergency Medicine.)

Purpose: In 2002, the Centers for Disease Control and Prevention (CDC) broadened the pelvic inflammatory disease (PID) diagnostic criteria to increase detection and prevent serious sequelae of untreated PID. The impact of this change on PID detection is unknown. Our objectives were to estimate trends in PID diagnosis among adolescent emergency department (ED) patients before and after the revised CDC definition and to identify factors associated with PID diagnoses., Methods: We performed a retrospective repeated cross-sectional study using the National Hospital Ambulatory Medical Care Survey from 2000 to 2009 of ED visits by 14- to 21-year-old females. We calculated national estimates of PID rates and performed multivariable logistic regression analyses and tests of trends., Results: During 2000-2009, of the 77 million female adolescent ED visits, there were an estimated 704,882 (95% confidence interval [CI], 571,807-837,957) cases of PID. After the revised criteria, PID diagnosis declined from 5.4 cases per 1,000 United States adolescent females to 3.9 cases per 1,000 (p = .03). In a multivariable model, age ≥17 years (odds ratio, 2.14; 95% CI, 1.25-3.64) and black race (odds ratio, 2.04; 95% CI, 1.36-3.07) were associated with PID diagnosis., Conclusions: Despite broadened CDC diagnostic criteria, PID diagnoses did not increase over time. This raises concern about awareness and incorporation of the new guidelines into clinical practice., (Copyright © 2013 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Background: The Centers for Disease Control and Prevention (CDC) 12-Step Campaign to Prevent Antimicrobial Resistance was launched to educate clinicians about antimicrobial resistance and provide strategies to improve clinical practice, including antimicrobial utilization., Methods: A multicenter retrospective observational study of antibiotic use was performed in 4 tertiary care NICUs to assess adherence to the guidelines defined by the CDC 12-Step Campaign using predetermined criteria. Fifty infants per NICU were identified who received intravenous antibiotics at greater than 72 hours of age. Antibiotic regimens, clinical and microbiologic data, and indications for initiation and continuation of antibiotics (after 72 hours of use) were recorded. Inappropriate utilization was characterized at initiation, continuation, by agent, and by CDC 12-Step., Results: Two hundred neonates received 323 antibiotic courses totaling 3344 antibiotic-days. Ninety (28%) courses and 806 (24%) days were judged to be nonadherent to a CDC 12-Step. Inappropriate use was more common with continuation of antibiotics (39%) than with initiation (4%) of therapy. Vancomycin was the most commonly used drug (n = 895 antibiotic-days) of which 284 (32%) days were considered inappropriate. Carbapenems were used less frequently (n = 310 antibiotic-days), and 132 (43%) of these days were inappropriate. Common reasons for nonadherence at the time of continuation included failure to narrow antibiotic coverage after microbiologic results were known and prolonged antibiotic prophylaxis after surgery with chest tube placement., Conclusions: The CDC 12-Step Campaign can be modified for neonatal populations. Inappropriate antibiotic prescribing was common in the study NICUs. Improvement efforts should target antibiotic use 72 hours after initiation, particularly focusing on narrowing therapy and instituting protocols to limit prophylaxis.

About two years ago, the death of a high school student athlete brought methicillin-resistant Staphylococcus aureus (MRSA) into the national spotlight. Preventing the spread of MRSA in schools, gyms, and other public facilities is an important public health goal. This Issue Brief presents current information on the prevalence and transmission of MRSA in community settings, and describes ongoing research on interventions to limit the spread of this increasingly common infection.

Objective: Clostridium difficile is the main cause of nosocomial and antibiotic-associated diarrhea in adults. Recently, the incidence and severity of C difficile-associated disease in adults have been increasing. Whether similar phenomena are occurring among children remains unknown. Our study describes the epidemiological features of C difficile-associated disease in hospitalized children., Methods: We conducted a retrospective cohort study of hospitalized children with C difficile-associated disease at 22 freestanding children's hospitals in the United States, from 2001 to 2006. Cases of C difficile-associated disease were defined as a hospitalized child with a discharge code for C difficile infection, a laboratory billing charge for a C difficile toxin assay, and receipt of antimicrobial therapy for C difficile-associated disease., Results: We identified 4895 patients with C difficile-associated disease. Over the study period, the annual incidence of C difficile-associated disease increased from 2.6 to 4.0 cases per 1000 admissions and from 4.4 to 6.5 cases per 10 000 patient-days. The median age of children with C difficile-associated disease was 4 years. Twenty-six percent of patients were <1 year of age. The majority of patients (67%) had underlying chronic medical conditions. The colectomy and all-cause mortality rates among children with C difficile-associated disease did not increase during the study period., Conclusions: The annual incidence of C difficile-associated disease in hospitalized children increased significantly from 2001 to 2006. However, the rates of colectomy and in-hospital death have not increased in children with C difficile-associated disease as they have among adults. The risk factors and outcomes for children with C difficile-associated disease remain to be defined in future studies.
