Quantifying Empiric Antibiotic Use in US Children’s Hospitals

OBJECTIVES Empirical broad-spectrum antibiotics are routinely administered for short durations to children with suspected bacteremia while awaiting blood culture results. Our aim for this study was to estimate the proportion of broad-spectrum antibiotic use accounted for by these “rule-outs.” METHODS The Pediatric Health Information System was used to identify children aged 3 months to 20 years hospitalized between July 2016 and June 2017 who received broad-spectrum antibiotics for suspected bacteremia. Using an electronic definition for a rule-out, we estimated the proportion of all broad-spectrum antibiotic days of therapy accounted for by this indication. Clinical and demographic characteristics, as well as antibiotic choice, are reported descriptively. RESULTS A total of 67 032 episodes of suspected bacteremia across 42 hospitals were identified. From these, 34 909 (52%) patients were classified as having received an antibiotic treatment course, and 32 123 patients (48%) underwent an antibiotic rule-out without a subsequent treatment course. Antibiotics prescribed for rule-outs accounted for 12% of all broad-spectrum antibiotic days of therapy. Third-generation cephalosporins and vancomycin were the most commonly prescribed antibiotics, and substantial hospital-level variation in vancomycin use was identified (range: 16%–58% of suspected bacteremia episodes). CONCLUSIONS Broad-spectrum intravenous antibiotic use for rule-out infections appears common across children’s hospitals, with substantial hospital-level variation in the use of vancomycin in particular. Antibiotic stewardship programs focused on intervening on antibiotics prescribed for longer durations may consider this novel opportunity to further standardize antibiotic regimens and reduce antibiotic exposure.

Abstract Background Understanding patterns of inpatient antibiotic use is necessary to enhance appropriate use and minimize preventable harm at hospitals. Few studies have characterized antibiotic use in the inpatient setting in children. Methods We conducted a cross-sectional study in children admitted to 51 freestanding US children’s hospitals included in the Pediatric Health Information System (PHIS). Overall and broad-spectrum antibiotic use (see Table) were measured using charge data, and prevalence of use was assessed on a single day of each 2017–2018 season over one year. Comparisons were made based on clinical setting (medical vs. surgical), clinical unit (PICU, NICU, and all others), hospital, and region. We assessed the relationship between antibiotic use and median hospital case-mix index (CMI), a surrogate for clinical complexity. Results Of 52769 hospitalized children assessed on a study day, 19174 (36%) received antibiotics, and 6575 (12%) received broad-spectrum antibiotics (table). Overall antibiotic use prevalence varied across hospitals from 22% to 52% (Figure 1). Median hospital CMI had no significant relationship with overall antibiotic use and only a weak correlation (ρ=0.29) with broad-spectrum antibiotic use (Figure 2). Antibiotic use prevalence varied minimally by season, ranging from 36% in fall to 37% in summer. Antibiotic use prevalence was 29% (9470/32436) among medical patients and 48% (9704/20333) among surgical patients. The antibiotics most commonly administered in medical patients were ceftriaxone and ampicillin, while surgical patients most commonly received cefazolin and vancomycin. Regional prevalence ranged from 33% (Midwest) to 40% (West). By unit, PICU patients had the highest prevalence of overall [58% (4006/6874)] and broad-spectrum [27% (1830/6874)] antibiotic use. Children with complex chronic conditions accounted for 63% of hospitalized children but represented 72% of children receiving any antibiotic and 85% of those receiving broad-spectrum antibiotics. Conclusion We observed large and apparently unexplained variability in antibiotic use prevalence among children’s hospitals, clinical settings, and regions. This indicates potential opportunities for enhanced antibiotic stewardship activities.

AbstractObjective:To characterize the prevalence of and seasonal and regional variation in inpatient antibiotic use among hospitalized US children in 2017–2018.Design:We conducted a cross-sectional examination of hospitalized children. The assessments were conducted on a single day in spring (May 3, 2017), summer (August 2, 2017), fall (October 25, 2017), and winter (January 31, 2018). The main outcome of interest was receipt of an antibiotic on the study day.Setting:The study included 51 freestanding US children’s hospitals that participate in the Pediatric Health Information System (PHIS).Patients:This study included all patients <18 years old who were admitted to a participating PHIS hospital, excluding patients who were admitted solely for research purposes.Results:Of 52,769 total hospitalized children, 19,174 (36.3%) received antibiotics on the study day and 6,575 of these (12.5%) received broad-spectrum antibiotics. The overall prevalence of antibiotic use varied across hospitals from 22.3% to 51.9%. Antibiotic use prevalence was 29.2% among medical patients and 47.7% among surgical patients. Although there was no significant seasonal variation in antibiotic use prevalence, regional prevalence varied, ranging from 32.7% in the Midwest to 40.2% in the West (P < .001). Among units, pediatric intensive care unit patients had the highest prevalence of both overall and broad-spectrum antibiotic use at 58.3% and 26.6%, respectively (P < .001).Conclusions:On any given day in a national network of children’s hospitals, more than one-third of hospitalized children received an antibiotic, and 1 in 8 received a broad-spectrum antibiotic. Variation across hospitals, setting and regions identifies potential opportunities for enhanced antibiotic stewardship activities.

Purpose: Following updates to the Infectious Diseases Society of America (IDSA) practice guidelines for the Diagnosis and Treatment of Adults with Community-acquired Pneumonia in 2019, Hartford HealthCare implemented changes to the community acquired pneumonia (CAP) order-set in August 2020 to reflect criteria for the prescribing of broad-spectrum antimicrobial therapy. The objective of the study was to evaluate changes in broad-spectrum antibiotic days of therapy (DOT) following these order-set updates with accompanying provider education. Methods: This was a multi-center, quasi-experimental, retrospective study of patients with a diagnosis of CAP from September 1, 2019 to October 31, 2019 (pre-intervention) and September 1, 2020 to October 31, 2020 (post-intervention). Patients were identified using ICD-10 codes (A48.1, J10.00-J18.9) indicating lower respiratory tract infection. Data collected included demographics, labs and vitals, radiographic, microbiological, and antibiotic data. The primary outcome was change in broad-spectrum antibiotic DOT, specifically anti-pseudomonal β-lactams and anti-MRSA antibiotics. Secondary outcomes included guideline-concordance of initial antibiotics, utilization of an order-set to prescribe antibiotics, and length of stay (LOS). Results: A total of 331 and 352 patients were included in the pre- and post-intervention cohorts, respectively. There were no differences in order-set usage (10% vs 11.3%, P = .642) between the pre- and post-intervention cohort, respectively. The overall duration of broad-spectrum therapy was a median of 2 days (IQR 0-8 days) in the pre-intervention period and 0 days (IQR 0-4 days) in the post-intervention period ( P < .001). Patients in whom the order-set was used in the post-intervention period were more likely to have guideline-concordant regimens ([36/40] 90% vs [190/312] 60.9%; P = .003). Hospital LOS was shorter in the post-intervention cohort (4.8 days [2.9-7.2 days] vs 5.3 days [IQR 3.5-8.5 days], P = .002). Conclusion: Implementation of an updated CAP order-set with accompanying provider education was associated with reduced use of broad-spectrum antibiotics. Opportunities to improve compliance and thus further increase guideline-concordant therapy require investigation.

Abstract Background Prior to 2016, Denver Health Medical Center had a higher-than-expected rate of hospital onset Clostridium difficile infection (HO-CDI). A multifaceted CDI prevention plan was implemented, including the use of a probiotic as primary prevention for HO-CDI and antibiotic-associated diarrhea (AAD) in inpatients receiving broad-spectrum antibiotics. We aimed to study the effectiveness of probiotic use in this clinical context. Methods During the intervention, inpatient orders for a broad-spectrum antibiotic triggered a best practice advisory recommending once daily co-administration of 100 billion units of a probiotic containing Lactobacillus casei, L. rhamnosus, and L. acidophilus (BioK+ ®). To evaluate effectiveness and safety of this intervention, we performed a retrospective cohort study including adult inpatients who received > 24 hours of a broad-spectrum antibiotic between April 2016 and March 2018. The primary endpoint was the incidence of HO-CDI (> 3 days after admission) compared between patients who received antibiotics alone vs. antibiotics plus the probiotic. Secondary endpoints were the incidence of AAD, defined as a negative CDI test after antibiotic initiation, and the incidence of Lactobacillus species identified in clinical cultures. Results 3,291 patients were included; 1,835 received antibiotics alone and 1,456 received antibiotics plus the probiotic. Baseline characteristics between groups were similar, except patients in the antibiotic alone group had a greater incidence of cirrhosis and proton-pump inhibitor use (16.1% vs 10.1%, P < 0.001; 39.1% vs 31.5%, P < 0.001). Length of stay and antibiotic days of therapy were longer in the antibiotic plus probiotic group [6 days (IQR, 3–11) vs 6 days (IQR, 4–12), P = 0.014; 4 days (IQR, 3–7) vs 5 days (IQR, 3–7), P < 0.001]. The incidence of HO-CDI (37, 2% vs 35, 2.4%; P = 0.450) and AAD (231, 12.6% vs 199, 13.7%; P = 0.362) were similar between groups. Lactobacillus was identified in at least one clinical culture from 0.2% (3/1835) and 0.3% (4/1456) of patients in the antibiotic alone group and antibiotic plus probiotic group, respectively (P = 0.497). Conclusion In hospitalized patients receiving broad-spectrum antibiotics, co-administration of a probiotic did not appear to reduce the incidence of HO-CDI or AAD.

Broad Spectrum Antibiotics

Abstract Background Recognition of sepsis frequently occurs in the ED. To demonstrate the need to optimize antibiotic use for suspected sepsis and evaluate the reliability of systemic inflammatory response syndrome (SIRS) criteria in predicting bacterial infection, we quantified the rate of unnecessary intravenous (IV) broad-spectrum antibiotic use for suspected sepsis in the ED at an academic medical center. Methods Adult patients who were admitted to the ED between January 2018 and June 2018 with suspected sepsis (≥ 2 SIRS) and received ≥ 1 dose of IV broad-spectrum antibiotic were included in this retrospective study. The presence of bacterial infection was determined using Centers for Disease Control and Prevention (CDC)/National Healthcare Safety Network (NHSN) definitions, microbiologic, radiographic, and laboratory findings. Suspected infections lacked microbiologic data. The primary outcome was the percentage of confirmed and suspected infections. Secondary outcomes included 90-day Clostridioides difficile infection (CDI) and 90-day drug-resistant organism (DRO) infections. Results A total of 218 patients were included. The percentages of confirmed/suspected and absence of bacterial infections were 63.8% and 36.2%, respectively. Elevated SIRS (≥ 2) and Quick Sequential Organ Failure Assessment (qSOFA; ≥ 2) scores were not associated with the presence of bacterial infections. 82% of patients were discharged from the ED. Antibiotic exposure in days of therapy in the ED and/or hospital admission did not significantly vary between patients with confirmed/suspected bacterial infection and those with absence of bacterial infections. Among patients who lacked evidence of bacterial infections, 44% were prescribed outpatient antibiotics after being discharged from the ED. 90-day CDI and DRO infections were identified in 7 and 6 patients, respectively, regardless of the presence of bacterial infections. Table 1. Baseline demographics of patients admitted to the ED with suspected sepsis Conclusion A third of the patients with suspected sepsis received IV broad-spectrum antibiotics in the ED but ultimately lacked bacterial infection. Our findings suggest that identification of bacterial infection and patients with sepsis using SIRS or qSOFA lack specificity and can lead to the overuse of unnecessary antibiotics in the ED.

Objective.We aimed to rigorously evaluate the impact of prospective audit and feedback on broad-spectrum antimicrobial use among critical care patients.Design.Prospective, controlled interrupted time series.SettingSingle tertiary care center with 3 intensive care units.Patients and Interventions.A formal review of all critical care patients on their third or tenth day of broad-spectrum antibiotic therapy was conducted, and suggestions for antimicrobial optimization were communicated to the critical care team.Outcomes.The primary outcome was broad-spectrum antibiotic use (days of therapy per 1000 patient-days; secondary outcomes included overall antibiotic use, gram-negative bacterial susceptibility, nosocomial Clostridium difficile infections, length of stay, and mortality.Results.The mean monthly broad-spectrum antibiotic use decreased from 644 days of therapy per 1,000 patient-days in the preintervention period to 503 days of therapy per 1,000 patient-days in the postintervention period (P < .0001); time series modeling confirmed an immediate decrease (± standard error) of 119 ± 37.9 days of therapy per 1,000 patient-days (P = .0054). In contrast, no changes were identified in the use of broad-spectrum antibiotics in the control group (nonintervention medical and surgical wards) or in the use of control medications in critical care (stress ulcer prophylaxis). The incidence of nosocomial C. difficile infections decreased from 11 to 6 cases in the study intensive care units, whereas the incidence increased from 87 to 116 cases in the control wards (P = .04). Overall gram-negative susceptibility to meropenem increased in the critical care units. Intensive care unit length of stay and mortality did not change.Conclusions.Institution of a formal prospective audit and feedback program appears to be a safe and effective means to improve broad-spectrum antimicrobial use in critical care.

QuestionIs broad-spectrum antibiotic use associated with poor outcomes in community-onset pneumonia after adjusting for confounders?MethodsWe performed a retrospective, observational cohort study of 1995 adults with pneumonia admitted from four US hospital emergency departments. We used multivariable regressions to investigate the effect of broad-spectrum antibiotics on 30-day mortality, length of stay, cost and Clostridioides difficile infection (CDI). To address indication bias, we developed a propensity score using multilevel (individual provider) generalised linear mixed models to perform inverse-probability of treatment weighting (IPTW) to estimate the average treatment effect in the treated. We also manually reviewed a sample of mortality cases for antibiotic-associated adverse events.Results39.7% of patients received broad-spectrum antibiotics, but drug-resistant pathogens were recovered in only 3%. Broad-spectrum antibiotics were associated with increased mortality in both the unweighted multivariable model (OR 3.8, 95% CI 2.5–5.9; p<0.001) and IPTW analysis (OR 4.6, 95% CI 2.9–7.5; p<0.001). Broad-spectrum antibiotic use by either analysis was also associated with longer hospital stay, greater cost and increased CDI. Healthcare-associated pneumonia was not associated with mortality independent of broad-spectrum antibiotic use. In manual review we identified antibiotic-associated events in 17.5% of mortality cases.ConclusionBroad-spectrum antibiotics appear to be associated with increased mortality and other poor outcomes in community-onset pneumonia.

The Impact

Background: Antimicrobial stewardship programs commonly utilize infectious diseases pharmacists to guide appropriate utilization of broad-spectrum antimicrobials. Strategies should be developed to increase staff pharmacist’s participation in decreasing broad-spectrum antibiotic use. Objective: The purpose of this study was to determine the effectiveness of a pharmacy-driven 72-hour antimicrobial stewardship initiative. Methods: A pharmacy-driven 72-hour antibiotic review policy was implemented at a community hospital. Targeted antibiotics included ertapenem, meropenem, and daptomycin. The hospital’s infectious diseases pharmacist provided policy education to staff pharmacists. All pharmacists provided prospective audit and feedback to physicians. Preimplementation and postimplementation data were collected through a retrospective chart review to analyze the impact of the initiative. Results: There were a total of 570 targeted antibiotic orders for review, of which 155 antibiotic orders met criteria for inclusion; 97 in the preimplementation group and 58 in the postimplementation group. Targeted antibiotic orders decreased postimplementation during the study period. Days of therapy per 1000 patient days decreased between the 2 groups, although this was statistically significant neither for the pooled targeted antibiotics nor for each individual antibiotic. There was a statistically significant increase in the number of appropriately prescribed targeted antibiotics from preimplementation compared to postimplementation (from 35% to 64%, P < .01). Pharmacist interventions documented for patients receiving the targeted antibiotics increased significantly during the intervention period ( P < .01). In addition, there was a total of $28 795.96 in cost avoidance based on the difference in antibiotic use between the 2 groups. Conclusion: Implementation of a pharmacy-driven 72-hour broad-spectrum antibiotic review in a large community-based hospital resulted in a reduction in utilization and hospital spending and a significant increase in appropriate use of targeted antibiotics, while also increasing pharmacist engagement with antimicrobial stewardship.

OBJECTIVETo explore the prevalence and drivers of hospital-level variability in antibiotic utilization among hematopoietic cell transplant (HCT) recipients to inform antimicrobial stewardship initiatives.DESIGNRetrospective cohort study using data merged from the Pediatric Health Information System and the Center for International Blood and Marrow Transplant Research.SETTINGThe study included 27 transplant centers in freestanding children’s hospitals.METHODSThe primary outcome was days of broad-spectrum antibiotic use in the interval from day of HCT through neutrophil engraftment. Hospital antibiotic utilization rates were reported as days of therapy (DOTs) per 1,000 neutropenic days. Negative binomial regression was used to estimate hospital utilization rates, adjusting for patient covariates including demographics, transplant characteristics, and severity of illness. To better quantify the magnitude of hospital variation and to explore hospital-level drivers in addition to patient-level drivers of variation, mixed-effects negative binomial models were also constructed.RESULTSAdjusted hospital rates of antipseudomonal antibiotic use varied from 436 to 1121 DOTs per 1,000 neutropenic days, and rates of broad-spectrum, gram-positive antibiotic use varied from 153 to 728 DOTs per 1,000 neutropenic days. We detected variability by hospital in choice of antipseudomonal agent (ie, cephalosporins, penicillins, and carbapenems), but gram-positive coverage was primarily driven by vancomycin use. Considerable center-level variability remained even after controlling for additional hospital-level factors. Antibiotic use was not strongly associated with days of significant illness or mortality.CONCLUSIONAmong a homogenous population of children undergoing HCT for acute leukemia, both the quantity and spectrum of antibiotic exposure in the immediate posttransplant period varied widely. Antimicrobial stewardship initiatives can apply these data to optimize the use of antibiotics in transplant patients.Infect Control Hosp Epidemiol 2018;797–805

The Impact

Abstract Background Children with perforated appendicitis have more frequent complications compared with nonperforated appendicitis. Existing data suggest broad-spectrum antibiotics are not superior to narrow-spectrum antibiotics for this condition. In an effort to safely decrease broad-spectrum antibiotic use at our hospital, we evaluated the impact of an antimicrobial stewardship program (ASP) intervention on the use of piperacillin/tazobactam (PT) and clinical outcomes in children with perforated appendicitis. Methods Single-center, retrospective cohort study of children ≤ 18 years with perforated appendicitis who underwent primary appendectomy. Children with primary nonoperative management or interval appendectomy were excluded. Prior to the intervention, children at our hospital routinely received PT for perforated appendicitis. An electronic health record (EHR)-integrated guideline that recommended ceftriaxone and metronidazole for perforated appendicitis was released on July 1, 2017 (Figure 1). We compared PT utilization, measured in days of therapy (DOT) per 1,000 patient-days, and clinical outcomes before and after the intervention. Results A total of 74 children with perforated appendicitis were identified: 23 during the pre-intervention period (June 1, 2016 to June 30, 2017) and 51 post-intervention (July 1, 2017 to September 30, 2018). Thirty-three patients (45%) were female and the median age was 8 years (IQR: 5–11.75 years). Post-intervention rate of guideline compliance was 84%. PT use decreased from 556 DOT per 1000 patient-days to 131 DOT per 1000 patient-days; incidence rate ratio of 0.24 (95% CI: 0.16–0.35), post-intervention vs. pre-intervention. There was no statistically significant difference in duration of intravenous antibiotics, total antibiotic duration, postoperative length of stay (LOS), total LOS, ED visits/readmission, or surgical site infection (SSI) between pre- and post-intervention periods (Table 1). Conclusion An EHR-integrated ASP intervention targeting children with perforated appendicitis resulted in decreased broad-spectrum antibiotic use with no statistically significant difference in clinical outcomes. Larger, multicenter trials are needed to confirm our findings. Disclosures All authors: No reported disclosures.
