RESUMEN
BACKGROUND: Providers must balance effective empiric therapy against toxicity risks and collateral damage when selecting antibiotic therapy for patients receiving hematopoietic cell transplant (HCT). Antimicrobial stewardship interventions during HCT are often challenging due to concern for undertreating potential infections. METHODS: In an effort to decrease unnecessary carbapenem exposure for patients undergoing HCT at our pediatric center, we implemented individualized antibiotic plans (IAPs) to provide recommendations for preengraftment neutropenia prophylaxis, empiric treatment of febrile neutropenia, and empiric treatment for hemodynamic instability. We compared monthly antibiotic days of therapy (DOT) adjusted per 1000 patient-days for carbapenems, antipseudomonal cephalosporins, and all antibiotics during two 3-year periods immediately before and after the implementation of IAPs to measure the impact of IAP on prescribing behavior. Bloodstream infection (BSIs) and Clostridioides difficile (CD) positivity test rates were also compared between cohorts. Last, providers were surveyed to assess their experience of using IAPs in antibiotic decision making. RESULTS: Overall antibiotic use decreased after the implementation of IAPs (monthly reduction of 19.6 DOT/1000 patient-days; P = .004), with carbapenems showing a continuing decline after IAP implementation. BSI and CD positivity rates were unchanged. More than 90% of providers found IAPs to be either extremely or very valuable for their practice. CONCLUSIONS: Implementation of IAPs in this high-risk HCT population led to reduction in overall antibiotic use without increase in rate of BSI or CD test positivity. The program was well received by providers.

BACKGROUND: Cerebrospinal fluid (CSF) shunts allow children with hydrocephalus to survive and avoid brain injury (J Neurosurg 107:345-57, 2007; Childs Nerv Syst 12:192-9, 1996). The Hydrocephalus Clinical Research Network implemented non-randomized quality improvement protocols that were shown to decrease infection rates compared to pre-operative prophylactic intravenous antibiotics alone (standard care): initially with intrathecal (IT) antibiotics between 2007-2009 (J Neurosurg Pediatr 8:22-9, 2011), followed by antibiotic impregnated catheters (AIC) in 2012-2013 (J Neurosurg Pediatr 17:391-6, 2016). No large scale studies have compared infection prevention between the techniques in children. Our objectives were to compare the risk of infection following the use of IT antibiotics, AIC, and standard care during low-risk CSF shunt surgery (i.e., initial CSF shunt placement and revisions) in children. METHODS: A retrospective observational cohort study at 6 tertiary care children's hospitals was conducted using Pediatric Health Information System + (PHIS +) data augmented with manual chart review. The study population included children ≤ 18 years who underwent initial shunt placement between 01/2007 and 12/2012. Infection and subsequent CSF shunt surgery data were collected through 12/2015. Propensity score adjustment for regression analysis was developed based on site, procedure type, and year; surgeon was treated as a random effect. RESULTS: A total of 1723 children underwent initial shunt placement between 2007-2012, with 1371 subsequent shunt revisions and 138 shunt infections. Propensity adjusted regression demonstrated no statistically significant difference in odds of shunt infection between IT antibiotics (OR 1.22, 95% CI 0.82-1.81, p = 0.3) and AICs (OR 0.91, 95% CI 0.56-1.49, p = 0.7) compared to standard care. CONCLUSION: In a large, observational multicenter cohort, IT antibiotics and AICs do not confer a statistically significant risk reduction compared to standard care for pediatric patients undergoing low-risk (i.e., initial or revision) shunt surgeries.

Importance: Acute sinusitis is one of the most common indications for antibiotic prescribing in children, with an estimated 4.9 million such prescriptions in the US annually. Consensus does not exist regarding the optimal empirical antibiotic. Objective: To compare amoxicillin-clavulanate vs amoxicillin for the treatment of acute sinusitis in outpatient children. Design, Setting, and Participants: Cohort study of children and adolescents aged 17 years or younger with a new outpatient diagnosis of acute sinusitis and a same-day new prescription dispensation of amoxicillin-clavulanate or amoxicillin in a nationwide health care utilization database. Propensity score matching was used to mitigate confounding. Exposure: A new prescription dispensation of amoxicillin-clavulanate or amoxicillin. Main Outcomes and Measures: Treatment failure, defined as an aggregate of a new antibiotic dispensation, emergency department or inpatient encounter for acute sinusitis, or inpatient encounter for a sinusitis complication, was assessed 1 to 14 days after cohort enrollment. Adverse events were evaluated, including gastrointestinal symptoms, hypersensitivity and skin reactions, acute kidney injury, and secondary infections. Results: The cohort included 320â¯141 patients. After propensity score matching, there were 198â¯942 patients (99â¯471 patients per group), including 100â¯340 (50.4%) who were female, 101â¯726 (51.1%) adolescents aged 12 to 17 years, 52â¯149 (26.2%) children aged 6 to 11 years, and 45â¯067 (22.7%) children aged 0 to 5 years. Treatment failure occurred in 1.7% overall; 0.01% had serious failure (an emergency department or inpatient encounter). There was no difference in the risk of treatment failure between the amoxicillin-clavulanate and amoxicillin groups (relative risk [RR], 0.98 [95% CI, 0.92-1.05]). The risk of gastrointestinal symptoms (RR, 1.15 [95% CI, 1.05-1.25]) and yeast infections (RR, 1.33 [95% CI, 1.16-1.54]) was higher with amoxicillin-clavulanate. After patients were stratified by age, the risk of treatment failure after amoxicillin-clavulanate was an RR of 0.98 (95% CI, 0.86-1.12) for ages 0 to 5 years; RR was 1.06 (95% CI, 0.92-1.21) for 6 to 11 years; and RR was 0.87 (95% CI, 0.79-0.95) for 12 to 17 years. The age-stratified risk of adverse events after amoxicillin-clavulanate was an RR of 1.23 (95% CI, 1.10-1.37) for ages 0 to 5 years; RR was 1.19 (95% CI, 1.04-1.35) for 6 to 11 years; and RR was 1.04 (95% CI, 0.95-1.14) for 12 to 17 years. Conclusions and Relevance: In children with acute sinusitis who were treated as outpatients, there was no difference in the risk of treatment failure between those who received amoxicillin-clavulanate compared with amoxicillin, but amoxicillin-clavulanate was associated with a higher risk of gastrointestinal symptoms and yeast infections. These findings may help inform decisions for empirical antibiotic selection in acute sinusitis.

BACKGROUND: Pulmonary exacerbations (PEx) in people with cystic fibrosis (PwCF) are associated with significant morbidity. While standard PEx treatment for PwCF with Pseudomonas aeruginosa infection includes two IV antipseudomonal antibiotics, little evidence exists to recommend this approach. This study aimed to compare clinical outcomes of single versus double antipseudomonal antibiotic use for PEx treatment. METHODS: Retrospective cohort study using the linked CF Foundation Patient Registry-Pediatric Health Information System dataset. PwCF were included if hospitalized between 2007 and 2018 and 6-21 years of age. Regression modeling accounting for repeated measures was used to compare lung function outcomes between single versus double IV antipseudomonal antibiotic regimens using propensity-score weighting to adjust for relevant confounding factors. RESULTS: Among 10,660 PwCF in the dataset, we analyzed 2,578 PEx from 1,080 PwCF, of which 455 and 2,123 PEx were treated with 1 versus 2 IV antipseudomonal antibiotics, respectively. We identified no significant differences between PEx treated with 1 versus 2 IV antipseudomonal antibiotics either in change between pre- and post-PEx percent predicted forced expiratory volume in one second (ppFEV1) (-0.84%, [95% CI -2.25, 0.56]; P = 0.24), odds of returning to ≥90% of baseline ppFEV1 within 3 months following PEx (Odds Ratio 0.83, [95% CI 0.61, 1.13]; P = 0.24) or time to next PEx requiring IV antibiotics (Hazard Ratio 1.04, [95% CI 0.87, 1.24]; P = 0.69). CONCLUSIONS: Use of 2 IV antipseudomonal antibiotics for PEx treatment in young PwCF was not associated with greater improvements in measured respiratory and clinical outcomes compared to treatment with 1 IV antipseudomonal antibiotic.

BACKGROUND: Studies estimate that 30%-50% of antibiotics prescribed for hospitalized patients are inappropriate, but pediatric data are limited. Characterization of inappropriate prescribing practices for children is needed to guide pediatric antimicrobial stewardship. METHODS: Cross-sectional analysis of antibiotic prescribing at 32 children's hospitals in the United States. Subjects included hospitalized children with ≥ 1 antibiotic order at 8:00 am on 1 day per calendar quarter, over 6 quarters (quarter 3 2016-quarter 4 2017). Antimicrobial stewardship program (ASP) physicians and/or pharmacists used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. The primary outcome was the percentage of antibiotics prescribed for infectious use that were classified as suboptimal, defined as inappropriate or needing modification. RESULTS: Of 34 927 children hospitalized on survey days, 12 213 (35.0%) had ≥ 1 active antibiotic order. Among 11 784 patients receiving antibiotics for infectious use, 25.9% were prescribed ≥ 1 suboptimal antibiotic. Of the 17 110 antibiotic orders prescribed for infectious use, 21.0% were considered suboptimal. Most common reasons for inappropriate use were bug-drug mismatch (27.7%), surgical prophylaxis > 24 hours (17.7%), overly broad empiric therapy (11.2%), and unnecessary treatment (11.0%). The majority of recommended modifications were to stop (44.7%) or narrow (19.7%) the drug. ASPs would not have routinely reviewed 46.1% of suboptimal orders. CONCLUSIONS: Across 32 children's hospitals, approximately 1 in 3 hospitalized children are receiving 1 or more antibiotics at any given time. One-quarter of these children are receiving suboptimal therapy, and nearly half of suboptimal use is not captured by current ASP practices.

OBJECTIVES: Children with urinary tract infection (UTI) are often diagnosed in emergency and urgent care settings and increasingly are unnecessarily treated with broad-spectrum antibiotics. This study evaluated the effect of a quality improvement intervention on empiric antibiotic prescribing for the treatment of uncomplicated UTI in children. METHODS: A local clinical pathway for uncomplicated UTI, introduced in June 2010, recommended empiric treatment with cephalexin, a narrow-spectrum (first-generation) cephalosporin antibiotic. A retrospective quasi-experimental study of pediatric patients older than 1 month presenting to emergency and urgent care settings from January 1, 2009, to December 31, 2014, with uncomplicated UTI was conducted. Hospitalized patients and those with chronic conditions or urogenital abnormalities were excluded. Control charts and interrupted time-series analysis were used to analyze the primary outcome of narrow-spectrum antibiotic prescribing rates and the balancing measures of 72-hour revisits, resistant bacterial isolates, and subsequent inpatient admissions for UTI. RESULTS: A total of 2134 patients were included. There was an immediate and sustained significant increase in cephalexin prescribing before (19.2%) versus after (79.6%) pathway implementation and a concurrent significant decline in oral third-generation cephalosporin (cefixime) prescribing from 50.3% to 4.0%. There was no significant increase in 72-hour revisits, resistant bacterial isolates, or inpatient admissions for UTI. CONCLUSIONS: A clinical pathway produced a significant and sustained increase in narrow-spectrum empiric antibiotic prescribing for pediatric UTI. Increased empiric cephalexin prescribing did not result in increased treatment failures or adverse patient outcomes. Future studies on implementing clinical pathways for children outside a pediatric hospital network are needed.

The purpose of this study was to create national estimates for the incidence of pediatric infective endocarditis (IE) in the United States and to determine if these changed after the implementation of the 2007 American Heart Association IE guidelines. It also sought to determine the effect of congenital heart disease (CHD) status on outcomes in IE. Hospital discharges with the diagnosis of IE in patients < 18 years old from the Kids' Inpatient Database were identified from the years 2000, 2003, 2006, 2009, and 2012. Discharges were grouped into Pre- and Post-2007 groups to facilitate analysis surrounding the implementation of the guidelines in 2007. Patients were categorized by age, underlying CHD, and etiologic organism. Descriptive comparisons and changes in categorical variables were made between groups. Average annual IE hospitalization rates before and after the 2007 guidelines were 10.8 and 9.3 per 1,000,000 children, respectively. The proportion of IE patients with CHD was stable between time periods, (45% vs. 47%, p = 0.50). Mortality was higher in the Post-2007 time period for CHD patients than non-CHD patients (11.1% vs. 2.4%, respectively; p < 0.001), while there was no difference noted during the Pre-2007 time period (6.5% vs. 6.6%, respectively; p = 0.95). Streptococcus was more common among CHD patients than non-CHD patients (27% vs. 17%), while Staphylococcus was more common among non-CHD patients than CHD patients (34% vs. 24%, p < 0.001). Even though the incidence of IE was stable over time, mortality was higher in CHD patients after the implementation of the 2007 AHA IE prophylaxis guidelines.

OBJECTIVE: The aim of this study was to compare the effectiveness of extended versus narrow spectrum antibiotics in preventing surgical site infections (SSIs) and hospital revisits in children with uncomplicated appendicitis. SUMMARY OF BACKGROUND DATA: There is a paucity of high-quality evidence in the pediatric literature comparing the effectiveness of extended versus narrow-spectrum antibiotics in the prevention of SSIs associated with uncomplicated appendicitis. METHODS: Clinical data from the ACS NSQIP-Pediatric Appendectomy Pilot Project were merged with antibiotic utilization data from the Pediatric Health Information System database for patients undergoing appendectomy for uncomplicated appendicitis at 17 hospitals from January 1, 2013 to June 30, 2015. Patients who received piperacillin/tazobactam (extended spectrum) were compared with those who received either cefoxitin or ceftriaxone with metronidazole (narrow spectrum) after propensity matching on demographic and severity characteristics. Study outcomes were 30-day SSI and hospital revisit rates. RESULTS: Of the 1389 patients included, 39.1% received piperacillin/tazobactam (range by hospital: 0% to 100%), and the remainder received narrow-spectrum agents. No differences in demographics or severity characteristics were found between groups following matching. In the matched analysis, the rates of SSI were similar between groups [extended spectrum: 2.4% vs narrow spectrum 1.8% (odds ratio, OR: 1.05, 95% confidence interval, 95% CI 0.34-3.26)], as was the rate of revisits [extended spectrum: 7.9% vs narrow spectrum 5.1% (OR: 1.46, 95% CI 0.75-2.87)]. CONCLUSIONS: Use of extended-spectrum antibiotics was not associated with lower rates of SSI or hospital revisits when compared with narrow-spectrum antibiotics in children with uncomplicated appendicitis. Our results challenge the routine use of extended-spectrum antibiotics observed at many hospitals, particularly given the increasing incidence of antibiotic-resistant organisms.

OBJECTIVES: To characterize and compare antibiotic prescribing across PICUs to evaluate the degree of variability. DESIGN: Retrospective analysis from 2010 through 2014 of the Pediatric Health Information System. SETTING: Forty-one freestanding children's hospital. SUBJECTS: Children aged 30 days to 18 years admitted to a PICU in children's hospitals contributing data to Pediatric Health Information System. INTERVENTIONS: To normalize for potential differences in disease severity and case mix across centers, a subanalysis was performed of children admitted with one of the 20 All Patient Refined-Diagnosis Related Groups and the seven All Patient Refined-Diagnosis Related Groups shared by all PICUs with the highest antibiotic use. RESULTS: The study included 3,101,201 hospital discharges from 41 institutions with 386,914 PICU patients. All antibiotic use declined during the study period. The median-adjusted antibiotic use among PICU patients was 1,043 days of therapy/1,000 patient-days (interquartile range, 977-1,147 days of therapy/1,000 patient-days) compared with 893 among non-ICU children (interquartile range, 805-968 days of therapy/1,000 patient-days). For PICU patients, the median adjusted use of broad-spectrum antibiotics was 176 days of therapy/1,000 patient-days (interquartile range, 152-217 days of therapy/1,000 patient-days) and was 302 days of therapy/1,000 patient-days (interquartile range, 220-351 days of therapy/1,000 patient-days) for antimethicillin-resistant Staphylococcus aureus agents, compared with 153 days of therapy/1,000 patient-days (interquartile range, 130-182 days of therapy/1,000 patient-days) and 244 days of therapy/1,000 patient-days (interquartile range, 203-270 days of therapy/1,000 patient-days) for non-ICU children. After adjusting for potential confounders, significant institutional variability existed in antibiotic use in PICU patients, in the 20 All Patient Refined-Diagnosis Related Groups with the highest antibiotic usage and in the seven All Patient Refined-Diagnosis Related Groups shared by all 41 PICUs. CONCLUSIONS: The wide variation in antibiotic use observed across children's hospital PICUs suggests inappropriate antibiotic use.

The objective of this study was to assess the association between previous antibiotic use, particularly long-term prophylaxis, and the occurrence of subsequent resistant infections in children with index infections due to extended-spectrum-cephalosporin-resistant Enterobacteriaceae We also investigated the concordance of the index and subsequent isolates. Extended-spectrum-cephalosporin-resistant Escherichia coli and Klebsiella spp. isolated from normally sterile sites of patients aged <22 years were collected along with associated clinical data from four freestanding pediatric centers. Subsequent isolates were categorized as concordant if the species, resistance determinants, and fumC-fimH (E. coli) or tonB (Klebsiella pneumoniae) type were identical to those of the index isolate. In total, 323 patients had 396 resistant isolates; 45 (14%) patients had ≥1 subsequent resistant infection, totaling 73 subsequent resistant isolates. The median time between the index and first subsequent infections was 123 (interquartile range, 43 to 225) days. In multivariable Cox proportional hazards analyses, patients were 2.07 times as likely to have a subsequent resistant infection (95% confidence interval, 1.11 to 3.87) if they received prophylaxis in the 30 days prior to the index infection. In 26 (58%) patients, all subsequent isolates were concordant with their index isolate, and 7 (16%) additional patients had at least 1 concordant subsequent isolate. In 12 of 17 (71%) patients with E. coli sequence type 131 (ST131)-associated type 40-30, all subsequent isolates were concordant. Subsequent extended-spectrum-cephalosporin-resistant infections are relatively frequent and are most commonly due to bacterial strains concordant with the index isolate. Further study is needed to assess the role prophylaxis plays in these resistant infections.

GOALS: The aim of this study was to compare upper gastrointestinal (UGI) versus lower gastrointestinal (LGI) delivery routes of fecal microbiota transplantation (FMT) for refractory or recurrent/relapsing Clostridium difficile infection (CDI). BACKGROUND: FMT has been proven to be a safe and highly effective therapeutic option for CDI. Delivery, however, could be via the UGI or LGI routes, and it is unclear as to which route provides better clinical outcome. STUDY: A systematic search for studies that reported the use of FMT for CDI treatment was conducted. Individual patient data that included demographic (age and sex) and clinical (route of FMT delivery, CDI outcome after FMT, and follow-up time) information were obtained. Kaplan-Meier cumulative hazard curves and Cox proportional hazard models were used to assess clinical failure after FMT by the route of delivery. RESULTS: Data from 305 patients treated with FMT (208 via LGI route and 97 via UGI route) for CDI were analyzed. At 30 and 90 days, the risk of clinical failure was 5.6% and 17.9% in the UGI group compared with 4.9% and 8.5% in the LGI delivery route group, respectively. A time-varying analysis suggested a 3-fold increase in hazard of clinical failure for UGI delivery (hazard ratio, 3.43; 95% confidence interval, 1.32-8.93) in the period after 30 days. CONCLUSIONS: FMT delivered via the LGI seems to be the most effective route for the prevention of recurrence/relapse of CDI. A randomized controlled trial is necessary to confirm whether FMT delivered via the LGI is indeed superior to that delivered via the UGI route.

The objective of this study was to determine whether antibiotic exposure is associated with extended-spectrum-beta-lactamase- or AmpC-producing Escherichia coli or Klebsiella pneumoniae infections in children. We collected extended-spectrum-beta-lactamase- or AmpC-producing E. coli or K. pneumoniae isolates and same-species susceptible controls from normally sterile sites of patients aged ≤21 years, along with associated clinical data, at four free-standing pediatric centers. After controlling for potential confounders, the relative risk of having an extended-spectrum-beta-lactamase-producing isolate rather than a susceptible isolate was 2.2 times higher (95% confidence interval [CI], 1.49 to 3.35) among those with antibiotic exposure in the 30 days prior to infection than in those with no antibiotic exposure. The results were similar when analyses were limited to exposure to third-generation cephalosporins, other broad-spectrum beta-lactams, or trimethoprim-sulfamethoxazole. Conversely, the relative risk of having an AmpC-producing versus a susceptible isolate was not significantly elevated with any antibiotic exposure in the 30 days prior to infection (adjusted relative risk ratio, 1.12; 95% CI, 0.65 to 1.91). However, when examining subgroups of antibiotics, the relative risk of having an AmpC-producing isolate was higher for patients with exposure to third-generation cephalosporins (adjusted relative risk ratio, 4.48; 95% CI, 1.75 to 11.43). Dose-response relationships between antibiotic exposure and extended-spectrum-beta-lactamase-producing or AmpC-producing isolates were not demonstrated. These results reinforce the need to study and implement pediatric antimicrobial stewardship strategies, and they indicate that epidemiological studies of third-generation cephalosporin-resistant E. coli and K. pneumoniae isolates should include resistance mechanisms when possible.

OBJECTIVES: To describe the variation in approaches to surgical and antibiotic treatment for first cerebrospinal fluid (CSF) shunt infection and adherence to Infectious Diseases Society of America (IDSA) guidelines. STUDY DESIGN: We conducted a prospective cohort study of children undergoing treatment for first CSF infection at 7 Hydrocephalus Clinical Research Network hospitals from April 2008 through December 2012. Univariate analyses were performed to describe the study population. RESULTS: A total of 151 children underwent treatment for first CSF shunt-related infection. Most children had undergone initial CSF shunt placement before the age of 6 months (n = 98, 65%). Median time to infection after shunt surgery was 28 days (IQR 15-52 days). Surgical management was most often shunt removal with interim external ventricular drain placement, followed by new shunt insertion (n = 122, 81%). Median time from first negative CSF culture to final surgical procedure was 14 days (IQR 10-21 days). Median duration of intravenous (IV) antibiotic use duration was 19 days (IQR 12-28 days). For 84 infections addressed by IDSA guidelines, 7 (8%) met guidelines and 61 (73%) had longer duration of IV antibiotic use than recommended. CONCLUSIONS: Surgical treatment for infection frequently adheres to IDSA guidelines of shunt removal with external ventricular drain placement followed by new shunt insertion. However, duration of IV antibiotic use in CSF shunt infection treatment was consistently longer than recommended by the 2004 IDSA guidelines.

Fecal microbiota transplantation (FMT) is a safe and effective therapy for adults with recurrent Clostridium difficile colitis, but data regarding FMT in children are limited and focus on colonoscopic administration of FMT. We present 10 consecutive children who received FMT via nasogastric tube for treatment of recurrent C difficile infection. Median age was 5.4 years, and 30% were receiving simultaneous immunosuppression. Median follow-up was 44 days, and 90% of patients resolved their C difficile infection; one patient relapsed 2 months later after receiving antibiotics. FMT via nasogastric tube appears safe, well tolerated, and effective in treating pediatric recurrent C difficile colitis.

We examined the impact of the Pediatric Infectious Diseases Society/Infectious Diseases Society of America guidelines that recommend ampicillin or amoxicillin for children hospitalized with community-acquired pneumonia. Prescribing of ampicillin/amoxicillin increased following guideline publication, but remains low. Cephalosporin and macrolide prescribing decreased but remains common. Further studies exploring outcomes of and reasons for compliance with guidelines are warranted.

OBJECTIVES: The objective of this study was to perform a meta-analysis investigating antibiotic exposure as a risk factor for developing inflammatory bowel disease (IBD). METHODS: A literature search using Medline, Embase, and Cochrane databases was performed to identify studies providing data on the association between antibiotic use and newly diagnosed IBD. Included studies reported Crohn's disease (CD), ulcerative colitis (UC), or a composite of both (IBD) as the primary outcome and evaluated antibiotic exposure before being diagnosed with IBD. A random-effects meta-analysis was conducted to determine overall pooled estimates and 95% confidence intervals (CIs). RESULTS: A total of 11 observational studies (8 case-control and 3 cohort) including 7,208 patients diagnosed with IBD were analyzed. The pooled odds ratio (OR) for IBD among patients exposed to any antibiotic was 1.57 (95% CI 1.27-1.94). Antibiotic exposure was significantly associated with CD (OR 1.74, 95% CI 1.35-2.23) but was not significant for UC (OR 1.08, 95% CI 0.91-1.27). Exposure to antibiotics most markedly increased the risk of CD in children (OR 2.75, 95% CI 1.72-4.38). All antibiotics were associated with IBD, with the exception of penicillin. Exposure to metronidazole (OR 5.01, 95% CI 1.65-15.25) or fluoroquinolones (OR 1.79, 95% CI 1.03-3.12) was most strongly associated with new-onset IBD. CONCLUSIONS: Exposure to antibiotics appears to increase the odds of being newly diagnosed with CD but not UC. This risk is most marked in children diagnosed with CD.

Antibiotics are frequently utilized for cystic fibrosis (CF)-related pulmonary exacerbation treatment. The antibiotic spectrum index (ASI) is an antimicrobial stewardship tool developed to compare the relative breadth of individual antibiotics. This study aimed to create two expanded CF-specific ASI scoring indices for use in antimicrobial stewardship research and clinical care. The first scoring index expanded the original ASI to include bacterial microorganisms common to CF airway infections (CF-ASI). The second scoring system only included scores for bacterial microorganisms classically identified in CF airway infections (CF-sASI). Sixty-two antibiotics were evaluated and included in the updated ASIs. When multiple antibiotics are prescribed, we proposed using an additive ASI approach whereby the sum of the individual prescribed antibiotic scores represents the total ASI score. The application of CF-focused ASIs into CF research and stewardship programs can help to optimize antibiotic benefits, minimize harms and allow for increased sustainability of antibiotic use in CF.
RESUMEN
We sought to evaluate whether children hospitalized with acute respiratory infections experienced differences in antibiotic use by race and ethnicity. We found that likelihood of broad-spectrum antibiotic receipt differed across racial and ethnic groups. Future work should confirm this finding, evaluate causes, and ensure equitable antibiotic use.

We quantified antibiotic prescribing for ambulatory pediatric acute respiratory illness at 22 institutions in "pre-shortage" (Jan 2019-Sep 2022) and "shortage" (Oct 2022-Mar 2023) periods for amoxicillin. While acute respiratory illness prescribing increased across settings, the proportion of amoxicillin prescriptions decreased. Variation was seen within and between institutions.
