The Impact

Abstract Background Antibiotics are commonly administered in the peripartum period and most patients with penicillin allergy can tolerate beta lactams, which are preferred for the prophylaxis and treatment of several common obstetric infections. The purpose of this study was to evaluate the impact of a stewardship intervention bundle (including updates to institutional antibiotic guidelines, reclassification of severe penicillin allergy, development of order sets, and a physician champion) on the management of obstetric infections in patients with reported penicillin allergy. Methods This was a multicenter, retrospective study of adult patients presenting for labor and delivery who received at least one dose of antibiotics for an infectious indication May 1, 2018 to October 31, 2018 (pre-intervention) and May 1 2020 to October 31, 2020 (post-intervention). The primary outcome was the composite rates of patients with a reported penicillin allergy who received a preferred agent for Group B Streptococcus (GBS) prophylaxis, intraamniotic infection, or cesarean surgical site infection (SSI) prophylaxis. Results A total of 192 patients with a documented penicillin allergy were evaluated (96 patients each in pre- and post-intervention groups). Hives were the most commonly reported allergy in both groups (40% vs 39%, P=0.883). Following stewardship interventions, there was a significant increase in the rate of preferred antibiotics prescribed to patients with penicillin allergy (34.3% vs 84.3%, P< 0.001), driven mainly by patients with non-severe allergy (18.4% vs 82.9%, P< 0.001). There were non-statistically significant trends toward lower rates of postpartum endometritis, 30-day readmission, 90-day SSI, and neonatal early onset sepsis. Allergic reactions in the post-intervention group were limited to itching and rash in one patient each; both resolved with medical management. Conclusion A comprehensive antibiotic stewardship intervention increased preferred antibiotic prescribing for treatment and prophylaxis of obstetric infections. Pregnant patients with non-severe penicillin allergies, even those reporting hives, can tolerate beta-lactam antibiotics. The potential positive impact on clinical outcomes warrants additional investigation. Disclosures Neil Seligman, MD, Natera (Consultant)UpToDate (Other Financial or Material Support, Author)

The Impact

Antibiotic choice for pediatric community-acquired pneumonia (CAP) varies widely. We aimed to determine the impact of a 6-month personalized audit and feedback program on primary care providers’ antibiotic prescribing practices for CAP. Participants in the intervention group received monthly personalized feedback. We then analyzed enrolled providers’ CAP antibiotic prescribing practices. Participants diagnosed 316 distinct cases of CAP (214 control, 102 intervention); among these 316 participants, 301 received antibiotics (207 control, 94 intervention). In patients ≥5 years, the intervention group had fewer non–guideline-concordant antibiotics prescribed (22/103 [21.4%] control; 3/51 [5.9%] intervention, P < .05) and received more of the guideline-concordant antibiotics (amoxicillin and azithromycin). Personalized, scheduled audit and feedback in the outpatient setting was feasible and had a positive impact on clinician’s selection of guideline-recommended antibiotics. Audit and feedback should be combined with other antimicrobial stewardship interventions to improve guideline adherence in the management of outpatient CAP.

Abstract Background Empiric antibiotics for community acquired bacterial pneumonia (CABP) are often prescribed to patients with COVID-19, despite a low reported incidence of co-infections. Stewardship interventions targeted at facilitating appropriate antibiotic prescribing for CABP among COVID-19 patients are needed. We developed a guideline for antibiotic initiation and discontinuation for CABP in COVID-19 patients. The purpose of this study was to assess the impact of this intervention on the duration of empiric CABP antibiotic therapy among patients with COVID-19. Methods This was a single-center, retrospective, quasi-experimental study of adult patients admitted between 3/1/2020 to 4/25/2020 with COVID-19 pneumonia, who were initiated on empiric CABP antibiotics. Patients were excluded if they were initiated on antibiotics > 48 h following admission or if another source of infection was identified. The primary outcome was the duration of antibiotic therapy (DOT) prior to the guideline (March 1 to March27, 2020) and after guideline implementation (March 28 to April 25, 2020). We also evaluated the clinical outcomes (mortality, readmissions, length of stay) among those initiated on empiric CABP antibiotics. Results A total of 506 patients with COVID-19 were evaluated, 102 pre-intervention and 404 post-intervention. Prior to the intervention, 74.5% (n = 76) of patients with COVID-19 received empiric antibiotics compared to only 42% of patients post-intervention (n = 170), p < 0.001. The median DOT in the post-intervention group was 1.3 days shorter (p < 0.001) than the pre-intervention group, and antibiotics directed at atypical bacteria DOT was reduced by 2.8 days (p < 0.001). More patients in the post-intervention group were initiated on antibiotics based on criteria consistent with our guideline (68% versus 87%, p = 0.001). There were no differences between groups in terms of clinical outcomes. Conclusion Following the implementation of a guideline outlining recommendations for initiating and discontinuing antibiotics for CABP among COVID-19 inpatients, we observed a reduction in antibiotic prescribing and DOT. The guideline also resulted in a significant increase in the rate of guideline-congruent empiric antibiotic initiation.

Order Set

Abstract Background The Surviving Sepsis Campaign Guidelines recommends administration of broad-spectrum antibiotics within 1 hour of sepsis diagnosis; electronic order sets drive antibiotic selection with pre-populated regimens based on the suspected infectious indication. Given the low rate of cephalosporin cross-reactivity in patients with a PCN allergy, we modified our ED sepsis order set (Images 1 and 2) to include cephalosporin options in patients with reported mild-to-moderate PCN reaction histories. This was a single-center, retrospective analysis evaluating the impact of this change on antibiotic prescribing and associated outcomes. Methods An electronic medical record (EMR) report identified patients ≥18 years of age with a documented PCN allergy that received antibiotics via the ED sepsis order set from December 30, 2012 to September 28, 2013 (pre-intervention) and January 3, 2014 to July 18, 2015 (post-intervention). The primary objective was to compare antibiotic days of therapy (DOT) and length of therapy (LOT) between the pre- and post-groups. The secondary objectives included 30-day readmission and mortality, hospital length of stay (LOS), incidence of C. difficile within 6 months and documented hypersensitivity reactions. Bivariate analyses, with chi-square, Mann–Whitney U, and Poisson means test, were used. Results A total of 180 patients (90 pre- and 90 post-intervention) were included. Demographics were similar between groups, with the exception of congestive heart failure (CHF) which was more prevalent in the post-intervention group (P = 0.039). Aztreonam, vancomycin, aminoglycoside, and fluoroquinolone DOTs were significantly reduced (P &lt; 0.001) while cephalosporin DOTs significantly increased (P &lt; 0.001) in the post-intervention group. There were no statistical differences in antibiotic LOT, 30-day readmission and mortality, hospital LOS, or incidence of C. difficile infection. For those patients that received cephalosporin antibiotics, there were no hypersensitivity reactions documented in the EMR. Conclusion Stratifying ED sepsis order sets by PCN allergy history severity is a safe and effective intervention that reduces second-line antibiotics in PCN allergic patients presenting to the ED with suspected sepsis.

Abstract Background Pharmacist-driven protocols for utilization of methicillin-resistant Staphylococcus aureus (MRSA) nares screenings have shown to decrease duration of empiric gram-positive therapy and rates of acute kidney injury (AKI) in patients with respiratory infections. This study evaluated the impact of a pharmacist-driven MRSA nares screening protocol on duration of vancomycin or linezolid therapy (DT) in respiratory infections. Methods Patients aged 18 years and older with a medication order of vancomycin or linezolid for respiratory indication(s) were included. The MRSA nares screening protocol went into effect in October 2019. The protocol allowed pharmacists to order an MRSA nares polymerase chain reaction (PCR) for included patients, while the Antimicrobial Stewardship Program (ASP) made therapeutic recommendations for de-escalation of empiric gram-positive coverage based on negative MRSA nares screenings, if clinically appropriate. Data for the pre-intervention group was collected retrospectively for the months of October 2018 to March 2019. The post-intervention group data was collected prospectively for the months of October 2019 to March 2020. Results Ninety-seven patients were evaluated within both the pre-intervention group (n = 50) and post-intervention group (n = 57). Outcomes for DT (38.2 hours vs. 30.9 hours, P = 0.601) and AKI (20% vs. 14%, P = 0.4105) were not different before and after protocol implementation. A subgroup analysis revealed a significant reduction in DT within the pre- and post-MRSA PCR groups (38.2 hours vs. 24.8 hours, P = 0.0065) when pharmacist recommendations for de-escalation were accepted. Conclusion A pharmacist-driven MRSA nares screening protocol did not affect the duration of gram-positive therapy for respiratory indications. However, there was a reduction in DT when pharmacist-driven recommendations were accepted. Disclosures All Authors: No reported disclosures

Abstract Background To meet the core elements required for antimicrobial stewardship programs, our institution implemented a pharmacy-led antibiotic timeout (ATO) process in 2017 and a multidisciplinary ATO process in 2019. An antibiotic timeout is a discussion and review of the need for ongoing empirical antibiotics 2-4 days after initiation. This study sought to evaluate both the multidisciplinary ATO and the pharmacy-led ATO in a pediatric population, compare the impact of each intervention on antibiotic days of therapy (DOT) to a pre-intervention group without an ATO, and to then compare the impact of the pharmacy-led ATO versus multidisciplinary ATO on antibiotic days of therapy (DOT). Methods This was a retrospective, pre-post, quasi-experimental study of pediatric patients comparing antibiotic DOT prior to ATO implementation (pre-ATO), during the pharmacy-led ATO (pharm-ATO), and during the multidisciplinary ATO (multi-ATO). The pre-ATO group was a patient sample from February-September 2016, prior to the initiation of a formal ATO. The pharmacy-led ATO was implemented from February-September 2018. This was followed by a multidisciplinary ATO led by pediatric residents and nurses from February-September 2019. Both the pharm-ATO and the multi-ATO were implemented as an active non-interruptive alert added to the electronic health record patient list. This alert triggered when new antibiotics had been administered to the patient for 48 hours, at which time, the responsible clinician would discuss the antibiotic and document their decision via the alert workspace. Pediatric patients receiving IV or PO antibiotics administered for at least 48 hours were included. The primary outcome was DOT. Secondary outcomes included length of stay (LOS) and mortality. Results 1284 unique antibiotic orders (n= 572 patients) were reviewed in the pre-ATO group, 868 (n= 323 patients) in the pharm-ATO and 949 (n= 305 patients) in the multi-ATO groups. Average DOT was not significantly different pre vs post intervention for either methodology (Table 1). Mortality was similar between groups, but LOS was longer for both intervention groups (Table 1). Impact of an ATO on DOT, Mortality and LOS Conclusion An ATO had no impact on average antibiotic DOT in a pediatric population, regardless of the ATO methodology.

Abstract Background Outpatient antimicrobial prescribing is an important target for antimicrobial stewardship (AMS) interventions to decrease antimicrobial resistance in the United States. The objective of this study was to design, implement and evaluate the impact of AMS interventions focused on asymptomatic bacteriuria (ASB) and acute respiratory infections (ARIs) in the outpatient setting. Methods This randomized, stepped-wedge trial evaluated the impact of educational interventions to providers on adult patients presenting to primary care (PC) clinics for ARIs and ASB from 10/1/19 to 1/31/20. Data was collected by retrospective chart review. An antibiotic prescribing report card was provided to PC providers, then an educational session was delivered at each PC clinic. Patient education materials were distributed to PC clinics. Interventions were made in a step-wise (figure 1) fashion. The primary outcome was percentage of overall antibiotic prescriptions as a composite of prescriptions for ASB, acute bronchitis, upper-respiratory infection otherwise unspecified, uncomplicated sinusitis, and uncomplicated pharyngitis. Secondary outcomes included individual components of the primary outcome, a composite safety endpoint of related hospital, emergency department or primary care visit within 4 weeks, antibiotic appropriateness, and patient satisfaction surveys. Figure 1 Results There were 887 patients included for analysis (405 pre-intervention, 482 post-intervention). Baseline characteristics are summarized in table 1. After controlling for type 1 error using a Bonferroni correction the primary outcome was not significantly different between groups (56% vs 49%). There was a statistically significant decrease in prescriptions for bronchitis (20.99% vs 12.66%; p=0.0003). Appropriateness of prescriptions for sinusitis (OR 4.96; CI 1.79–13.75; p=0.0021) and pharyngitis (OR 5.36; CI 1.93 – 14.90; p=0.0013) was improved in the post-intervention group. The composite safety outcome and patient satisfaction survey ratings did not differ between groups. Table 1 Conclusion Multifaceted educational interventions targeting providers can improve antibiotic prescribing for indications rarely requiring antimicrobials without increasing re-visit or patient satisfaction surveys.

Abstract Background Although it is recommended that an OPAT program should be managed by a formal OPAT team that supports the treating physician, many OPAT programs face challenges in obtaining necessary program staff (i.e nurses or pharmacists) due to limited data examining the impact of a dedicated OPAT team on patient outcomes. Our objective was to compare OPAT-related readmission rates among patients receiving OPAT before and after the implementation of a strengthened OPAT program. Methods This retrospective quasi-experiment compared adult patients discharged on intravenous (IV) antibiotics from the University of Illinois Hospital before and after implementation of programmatic changes to strengthen the OPAT program. Data from our previous study were used as the pre-intervention group (1/1/2012 to 8/1/2013), where only individual infectious disease (ID) physicians coordinated OPAT. Post-intervention (10/1/2017 to 1/1/2019), a dedicated OPAT nurse provided full time support to the treating ID physicians through care coordination, utilization of protocols for lab monitoring and management, and enhanced documentation. Factors associated with readmission for OPAT-related problems at a significance level of p&lt; 0.1 in univariate analysis were eligible for testing in a forward stepwise multinomial logistic regression to identify independent predictors of readmission. Results Demographics, antimicrobial indications, and OPAT administration location of the 428 patients pre- and post-intervention are listed in Table 1. After implementation of the strengthened OPAT program, the readmission rate due to OPAT-related complications decreased from 17.8% (13/73) to 6.5% (23/355) (p=0.001). OPAT-related readmission reasons included: infection recurrence/progression (56%), adverse drug reaction (28%), or line-associated issues (17%). Independent predictors of hospital readmission due to OPAT-related problems are listed in Table 2. Table 1. OPAT Patient Demographics and Factors Pre- and Post-intervention Table 2. Factors independently associated with hospital readmission in OPAT patients Conclusion An OPAT program with dedicated staff at a large academic tertiary care hospital was independently associated with decreased risk for readmission, which provides critical evidence to substantiate additional resources being dedicated to OPAT by health systems in the future.

Abstract Background Chorioamnionitis may cause serious perinatal and neonatal adverse outcomes, and group B streptococcus (GBS) is one of the most common bacteria isolated from human chorioamnionitis. The present study analyzed the impact of GBS infection and histological chorioamnionitis (HCA) on pregnancy outcomes and the diagnostic value of various biomarkers. Methods Pregnant women were grouped according to GBS infection and HCA detection. Perinatal and neonatal adverse outcomes were recorded with a follow-up period of 6 weeks. The white blood cell count (WBC), neutrophil ratio, and C-reactive protein (CRP) level from peripheral blood and soluble intercellular adhesion molecule-1 (sICAM-1), interleukin 8 (IL-8), and tumor necrosis factor α (TNF-α) levels from cord blood were assessed. Results A total of 371 pregnant women were included. Pregnant women with GBS infection or HCA had a higher risk of pathological jaundice and premature rupture of membranes and higher levels of sICAM-1, IL-8, and TNF-α in umbilical cord blood. Univariate and multivariate regression analysis revealed that sICMA-1, IL-8, TNF-α, WBC, and CRP were significantly related to an increased HCA risk. For all included pregnant women, TNF-α had the largest receiver operating characteristic (ROC) area (area: 0.841; 95% CI: 0.778–0.904) of the biomarkers analyzed. TNF-α still had the largest area under the ROC curve (area: 0.898; 95% CI: 0.814–0.982) for non-GBS-infected pregnant women, who also exhibited a higher neutrophil ratio (area: 0.815; 95% CI: 0.645–0.985) and WBC (area: 0.849; 95% CI: 0.72–0.978), but all biomarkers had lower value in the diagnosis of HCA in GBS-infected pregnant women. Conclusion GBS infection and HCA correlated with several perinatal and neonatal adverse outcomes. TNF-α in cord blood and WBCs in peripheral blood had diagnostic value for HCA in non-GBS-infected pregnant women but not GBS-infected pregnant women.
