Introduction: Antibiotics are a class of natural and synthetic compounds that inhibit the growth of or kill other microorganisms. Overuse of antibiotic is one of the most important factors for the development and spread of resistance in the hospital, as well as in the community. Present study was designed to describe antibiotic use in children and to assess the impact of an educational intervention on antibiotic prescription. Methods: The present study was conducted in pediatric ward of a tertiary care institute. The study population included two groups of children – each having 250 children. The first group consisted of 250 consecutive children admitted in one unit of the pediatric ward and they were analyzed for antibiotic use without any prior priming of the members of the unit regarding rationality of antibiotic use. This was followed by an intervention in the form of a 3hour workshop for all members of the unit. The second group included another 250 children consecutively admitted in the wards after this intervention. Results: In Pre intervention group 55 (44%) children received antibiotics in rational way, while in Post intervention group 90(60.40%) children received antibiotic in rational way. One hundred and thirty-six children (49.4%) received antibiotics for respiratory tract infections, this being the commonest disease for which antibiotics were received. As seen in the table, unindicated use of antibiotic was significantly reduced in Post intervention group (p = 0.03). Conclusion: The present study included 500 children. There were 285 (57%) males and 215 (43%) females. Amongst these 500 patients, 178 (35.6%) were below 1 year of age. This group had the highest number of patients. In the Pre intervention group, 55 (44%) children received antibiotics rationally, while in Post intervention group 90(60.40%) children received antibiotic rationally.

Abstract Background In India, Candida bloodstream infections have a reported incidence of 1–12 per 1,000 admissions and a mortality rate of up to 60%. Antimicrobial stewardship programs (ASP) can improve quality of care and clinical outcomes. This study evaluates the impact of a comprehensive candidemia ASP bundle in a hospital in southern India with an established stewardship program. Methods A single-center, pre-post quasi-experimental study was conducted at a tertiary-care center in southern India to analyze the impact of an ASP care bundle for the management of adults with candidemia. During the intervention period (October 2017–December 2018), the ASP provided recommendations to providers in accordance with the 2016 IDSA Guidelines for the Management of Candidemia, which included the following bundle: (1) appropriate selection and dosing of antifungal therapy; (2) repeat blood cultures every 48 hours until clearance; (3) removal of central venous catheters and other potential removable foci of infection; (4) echocardiogram; (5) ophthalmologic evaluation; and (6) appropriate duration of therapy. The primary outcome was initiation of appropriate antifungal therapy. Additional clinical outcomes were also compared with a historical cohort. Results One hundred and four patients with candidemia were included: 52 in the pre-intervention and 52 in the post-intervention group. Overall, baseline demographics were similar between the two groups (Table 1). Candida tropicalis (26.9%) and Candida parapsilosis (29.8%) were the most common causes of candidemia in the cohort. Following intervention, administration of appropriate antifungal therapy improved by 40.4% (28.8% pre vs. 69.2% post, P < 0.01). Average time to effective treatment initiation following culture positivity decreased from 57.6 hours to 12 hours in the post-intervention group (P < 0.01). Thirty-day all-cause mortality was similar between the two groups (34.6% 38.4%, P = 0.84). Conclusion Implementation of a comprehensive candidemia care bundle by the ASP significantly improved the use and timing of initiation of appropriate antifungal therapy.

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 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.

AbstractBackgroundIn 2008–2009, the Canadian Institute for Health Information reported over 30,000 cases of sepsis hospitalizations in Canada, an increase of almost 4,000 from 2005. Mortality rates from severe sepsis and septic shock continue to remain greater than 30% in Canada and are significantly higher than other critical conditions treated in the emergency department (ED). Our group formed a multidisciplinary sepsis committee, conducted an ED process of care analysis, and developed a quality improvement protocol. The objective of this study was to evaluate the effects of this sepsis management bundle on patient mortality.MethodsThis before and after study was conducted in two large Canadian tertiary care EDs and included adult patients with suspected severe infection that met at least two systemic inflammatory response syndrome (SIRS) criteria. We studied the implementation of a sepsis bundle including triage flagging, RN medical directive, education campaign, and a modified sepsis protocol. The primary outcomes were 30-day all-cause mortality and sepsis protocol use.ResultsWe included a total of 167 and 185 patients in the pre- and post-intervention analysis, respectively. Compared to the pre-intervention group, mortality was significantly lower in the post-intervention group (30.7% versus 17.3%; absolute difference, 13.4%; 95% CI 9.8–17.0; p=0.006). There was also a higher rate of sepsis protocol use in the post-intervention group (20.3% versus 80.5%, absolute difference 60.2%; 95% CI 55.1–65.3; p<0.001). Additionally, we found shorter time-intervals from triage to MD assessment, fluid resuscitation, and antibiotic administration as well as lower rates of vasopressor requirements and ICU admission.InterpretationThe implementation of our multidisciplinary ED sepsis bundle, including improved early identification and protocolized medical care, was associated with improved time to achieve key therapeutic interventions and a reduction in 30-day mortality. Similar low-cost initiatives could be implemented in other EDs to potentially improve outcomes for this high-risk group of patients.

Background Direct oral anticoagulants (DOACs) have become popular alternatives to vitamin K antagonists for the treatment and prevention of thromboembolic diseases; however, there are limited data regarding the appropriate use of DOACs in clinical practice. To ensure safety and efficacy of these medications, it is important that decisions regarding their use in patients rely on the available evidence. Objective The purpose of this study was to evaluate the appropriateness of DOAC prescribing in adult patients before and after the implementation of a pharmacist-driven DOAC protocol. Methods Data were collected on adult patients admitted to a community teaching hospital who received DOAC therapy for at least 2 days between January and March 2015 (pre-intervention group) and between January and March 2016 (post-intervention group). These data were analyzed to measure inappropriately prescribed DOACs, defined based on DOAC indication, renal function, drug interactions, and other pertinent patient-specific factors. Prior to the start of data collection for the post-intervention group, a pharmacist-driven protocol was developed and implemented. DOAC education was provided to pharmacists, including an evidence-based prescribing table to guide appropriate DOAC therapy. Comparisons were made between the pre-intervention and post-intervention groups to determine the impact of the pharmacist-driven service on appropriate DOAC prescribing. Results Fifty patients were analyzed in the pre-intervention group compared with 85 patients in the post-intervention group, with a total of 333 and 816 doses administered, respectively. Of the total doses administered, 32.4% were considered inappropriate in the pre-intervention group compared with 13.8% in the post-intervention group (adjusted odds ratio [OR], 0.42, 95% CI, 0.19-0.96; p = 0.039). Conclusions Implementing a pharmacist-driven DOAC service significantly improved appropriate prescribing of these agents. Provider education regarding DOAC use is essential to further increase appropriate prescribing of DOACs, optimize patients' therapy, and prevent adverse drug events.

SummaryObjective: Based on US. Centers for Disease Control and Prevention recommendations, New York State enacted legislation in 2010 requiring healthcare providers to offer non-targeted human immunodeficiency virus (HIV) testing to all patients aged 13–64. Three New York City adult emergency departments implemented an electronic alert that required clinicians to document whether an HIV test was offered before discharging a patient. The purpose of this study was to assess the impact of the electronic alert on HIV testing rates and diagnosis of HIV positive individuals.Methods: During the pre-intervention period (2.5–4 months), an electronic “HIV Testing” order set was available for clinicians to order a test or document a reason for not offering the test (e.g., patient is not conscious). An electronic alert was then added to enforce completion of the order set, effectively preventing ED discharge until an HIV test was offered to the patient. We analyzed data from 79,786 visits, measuring HIV testing and detection rates during the pre-intervention period and during the six months following the implementation of the alert.Results: The percentage of visits where an HIV test was performed increased from 5.4% in the pre-intervention period to 8.7% (p<0.001) after the electronic alert. After the implementation of the electronic alert, there was a 61% increase in HIV tests performed per visit. However, the percentage of patients testing positive per total patients-tested was slightly lower in the post-intervention group than the pre-intervention group (0.48% vs. 0.55%), but this was not significant. The number of patients-testing positive per total-patient visit was higher in the post-intervention group (0.04% vs. 0.03%).Conclusions: An electronic alert which enforced non-targeted screening was effective at increasing HIV testing rates but did not significantly increase the detection of persons living with HIV. The impact of this electronic alert on healthcare costs and quality of care merits further examination.Citation: Schnall R, Liu N, Sperling J, Green R, Clark S, Vawdrey D.

Abstract Background Antibiotic time out (ATO) policies have been proposed by the Centers for Disease Control and Prevention to limit unnecessary use of antibiotics. Critically ill patients are often treated empirically with MRSA-active agents for a prolonged duration. The objective of this study was to assess the impact of an ATO policy by targeting empiric gram-positive coverage. Methods Before this intervention, linezolid required pre-approval by the antimicrobial stewardship program or infectious diseases (ID) consult service before dispensing, and no automatic ATO policy was in place for any agent. In 2018, restriction of linezolid was modified to allow 72 hours of empiric use in the intensive care unit (ICU). This retrospective, single-center, pre- post-intervention study looked at eight ICUs at our institution from two equal periods. Adults (age ≥ 18 years) were included who received an IV gram-positive antibiotic (IVGP-AB), specifically linezolid or vancomycin, used for empiric therapy and were admitted to the ICU. The primary outcome was antimicrobial consumption of IVGP-AB defined as days of therapy (DOT) per patient. Secondary outcomes included in-hospital length of stay (LOS), ICU LOS, in-hospital mortality, 30-day readmission, and incidence of acute kidney injury (AKI). Figure 1. Flowchart of patient inclusion into the study Results 2718 patients met criteria for inclusion in the study. 1091 patients were included in the pre-intervention group and 1627 patients were included in the post-intervention group. Baseline characteristics between the two groups were similar, with ID consults being higher in the pre-intervention group. Total mean DOT of IVGP-AB in pre- and- post-intervention groups was 4.97 days vs. 4.36 days, p&lt; 0.01. Secondary outcomes of in-hospital LOS, ICU LOS, and in-hospital mortality did not vary significantly between groups. Thirty-day readmission was lower in the post-intervention group (12.9% vs. 3.9%, p&lt; 0.01). AKI did not differ significantly between groups, however the need for renal replacement therapy was higher in the pre-intervention group (1.2% vs. 0.2%, p&lt; 0.01). Conclusion This study assessed the impact of an ATO policy allowing 72 hours of empiric linezolid in the ICU. We found a statistically significant reduction in days of therapy of IVGP-AB without increases in LOS, mortality, readmission, and AKI. Disclosures All Authors: No reported disclosures

Introduction: Antibiotic time-outs (ATO) are a recommended antimicrobial stewardship action, but data assessing their impact are lacking. This study investigated the impact of a systematic, pharmacist initiated ATO intervention. Methods: This pre-post study included inpatients on hospitalist and intensivist services receiving empiric antibiotics for ≥48 hours. The ATO was initiated by pharmacists after 48 hours of empiric therapy and the outcome was documented including antibiotic indication, plan, and duration. An electronic medical record (EMR) alert facilitated ATO completion and pharmacists and prescribers received education prior to implementation. The primary outcome was EMR documentation of an antibiotic plan by 72 hours. Secondary outcomes included antibiotic utilization and antibiotic therapy modifications by 2 hours. Results: 399 patients were included, 199 pre- and 200 post-intervention. The most common indications were pneumonia (32%), intra-abdominal infection (20%) and urinary tract infection (19%), with no between-group differences. EMR documentation of an antibiotic plan significantly improved in the post-intervention group (19% vs. 79%, p<0.0001) as did modifications to antibiotic therapy. The median duration of in-hospital antibiotic therapy was similar between groups (4.0 vs. 4.0 days, p = 0.2499). Approximately 45% of patients in each group received discharge antibiotics and median duration of discharge antibiotic therapy prescribed was reduced (7 vs. 5 days in the pre- and post-intervention groups, respectively; p = 0.0140). Discussion: Implementation of pharmacist initiated ATO was associated with improvements in supporting EMR documentation and antibiotic therapy modifications. These findings highlight an important role in which pharmacists can serve as part of a collaborative antibiotic stewardship team.

Abstract Background Β-lactam allergy assessment is endorsed by the IDSA as an antimicrobial stewardship tool to enhance the use of first-line agents. We evaluated the impact of pharmacist-driven penicillin (PCN) allergy assessment at the point of prescription on antibiotic use in our emergency department (ED). Methods Retrospective, quasi-experimental study of adult patients with a PCN allergy receiving antibiotics at a community hospital ED. The intervention comprised an ED pharmacist performing allergy assessment and discussing therapy options with providers at the point of prescription. The primary outcome was to evaluate impact on guideline-preferred antibiotic prescription in the ED pre-intervention (March 1, 2017–August 31, 2017) vs. post-intervention (March 1, 2018–August 31, 2018). Secondary outcomes included types of reported allergic reactions, safety of allergy assessment process, and impact on downstream antibiotic use. Results Overall, 381 patients were evaluated (256 pre-intervention, 125 post-intervention). The median age was similar between groups and 85% of patients presented to the ED from the community. Most common infectious syndromes encountered in the ED were UTIs (35%), respiratory tract infections (25%), and skin/soft-tissue infections (18%). The proportion of guideline-preferred antibiotic prescriptions in the ED increased from 37% pre to 44% post (P = 0.171). Proportion of fluoroquinolone (FQ) prescriptions in the ED was reduced from 37.5% pre to 26% post (P = 0.021). Proportion of cephalosporin prescriptions increased from 26% pre to 42% post (P = 0.002). Types of reported allergic reactions were similar between groups and 55% of patients had tolerated a β-lactam agent since the listed allergy. Overall, 70% of patients were hospitalized from the ED. Similar trends in antibiotic use were observed at admission – decreased FQs (38% pre vs. 27% post, P = 0.059), increased cephalosporins (24% pre vs. 38.4% post, P = 0.021). Two patients (1.6%) experienced a nonsevere reaction within 24 hours of β-lactam administration post-allergy assessment. Conclusion Pharmacist-driven PCN allergy assessment at the point of prescription in the ED was safe and effective at improving the use of guideline-preferred antibiotics and reducing FQ use.

Background: Limited sample size and disparate outcome measures can hinder the ability of antimicrobial stewardship programs to assess the utility of their quality improvement interventions. Desirability of outcome ranking (DOOR) is a novel methodology that incorporates multiple outcomes into a single value to more comprehensively compare therapeutic strategies. The objective of this study was to apply DOOR to a single center antibiotic stewardship intervention. Methods: A pre- and post-interventional study was conducted evaluating the impact of prospective pharmacist review of rapid molecular diagnostic testing (RDT) of blood cultures on antibiotic optimization. Outcomes included the percentage of patients who were switched to appropriate therapy, the time to appropriate therapy, and the percentage of patients who had missed de-escalation opportunities. Results: A total of 19 and 29 patients were included in the final analysis. The percentage of patients reaching appropriate therapy was 84% (16/19) and 97% ([28/29], p = 0.16) in the pre-intervention and post-intervention groups respectively. Median time to appropriate therapy was 26 hours and 36 minutes (IQR 13:05-50:45) and 22:40 (IQR 3:42-48:23, p = 0.32), respectively. One missed de-escalation opportunity was identified in the post-intervention group (0% vs 3%, p = 1.00). DOOR analysis indicated that the probability of a better outcome for the post-intervention group than the pre-intervention group was 58% (95% CI 54-62). Conclusion: In this analysis, DOOR revealed a benefit that would not have been apparent with traditional outcomes assessments. Antimicrobial stewardship programs conducting quality improvement studies should consider incorporating DOOR into their methodology.
