Abstract Objective: The BioFire FilmArray Respiratory Panel (RFA) has been proposed as a tool that can aid in the timely diagnosis and treatment of respiratory tract infections but its effect on antibiotic prescribing among adult patients has varied. We evaluated the impact of RFA result on antibiotic days of therapy (DOTs) in 2 distinct cohorts: hospitalized patients and patients discharged from the emergency department (ED). Design: Retrospective cohort study. Setting: The study was conducted in 3 community hospitals in Des Moines, Iowa, from March 3 to March 16, 2019. Patients: Adults aged >18 years. Methods: Potential outcome means and average treatment effects for RFA results on antibiotic DOTs were estimated. Inverse probability of treatment weighting with regression adjustment was used. Results: We identified 243 patients each in the hospitalized and ED-discharged cohorts. Among hospitalized patients, RFA results did not affect antibiotic DOTs. Among patients discharged from the ED, we found that if all patients had had influenza detected, the average DOTs would have been 2.3 DOTs (−3.2 to −1.4) less than the average observed if all the patients had had a negative RFA (P < .0001); no differences in DOTs were observed when comparing an RFA with a noninfluenza virus detected compared to an RFA with negative results. Conclusions: The impact of RFA results on antibiotic DOTs varies by clinical setting, and reductions were observed only among patients discharged from the ED who had influenza A or B detected.

Abstract Background Measuring antimicrobial consumption data is a foundation of antimicrobial stewardship programs. There is data to support antimicrobial scorecard utilization to improve antibiotic use in the outpatient setting. There is a lack of data on the impact of an antimicrobial scorecard for hospitalists. Our objective was to improve antibiotic prescribing amongst the hospitalist service through the development of an antimicrobial scorecard. Methods Conducted in a 451-bed teaching hospital amongst 22 full time hospitalists. The antimicrobial scorecard for 2019 was distributed in two phases. In October 2019, baseline antibiotic prescribing data (January – September 2019) was distributed. In January 2020, a second scorecard was distributed (October – December 2019) to assess the impact of the scorecard. The scorecard distributed via e-mail to physicians included: Antibiotic days of therapy/1,000 patient care days (corrected for attending census), route of antibiotic prescribing (% intravenous (IV) vs % oral (PO)) and percentage of patients prescribed piperacillin-tazobactam (PT) for greater than 3 days. Hospitalists received their data in rank order amongst their peers. Along with the antimicrobial scorecard, recommendations from the antimicrobial stewardship team were included for hospitalists to improve their antibiotic prescribing for these initiatives. Hospitalists demographics (years of practice and gender) were collected. Descriptive statistics were utilized to analyze pre and post data. Results Sixteen (16) out of 22 (73%) hospitalists improved their antibiotic prescribing from pre- to post-scorecard (χ 2(1)=3.68, p = 0.055). The median antibiotic days of therapy/1,000 patient care days decreased from 661 pre-scorecard to 618 post-scorecard (p = 0.043). The median PT use greater than 3 days also decreased significantly, from 18% pre-scorecard to 11% post-scorecard (p = 0.0025). There was no change in % of IV antibiotic prescribing and no correlation between years of experience or gender to antibiotic prescribing. Conclusion Providing antimicrobial scorecards to our hospitalist service resulted in a significant decrease in antibiotic days of therapy/1,000 patient care days and PT prescribing beyond 3 days.

Abstract Background Automatic antimicrobial stop orders (ASOs) are a stewardship initiative used to decrease days of therapy, prevent resistance, and reduce drug costs. Limited evidence outside of the perioperative setting exists on the effects of ASOs on broad spectrum antimicrobial use, discharge prescription duration, and effects of missed doses. This study aims to evaluate the impact of an ASO policy across a health system of adult academic and community hospitals for treatment of intra-abdominal (IAI) and urinary tract infections (UTI). ASO Outcome Definitions ASO Outcomes Methods This multicenter retrospective cohort study compared patients with IAI and UTI treated before and after implementation of an ASO. Patients over the age of 18 with a diagnosis of UTI or IAI and 48 hours of intravenous (IV) antimicrobial administration were included. Patients unable to achieve IAI source control within 48 hours or those with a concomitant infection were excluded. The primary outcome was the difference in sum length of antimicrobial therapy (LOT). Secondary endpoints include length and days of antimicrobial therapy (DOT) at multiple timepoints, all cause in hospital mortality and readmission, and adverse events such as rates of Clostridioides difficile infection. Outcomes were also evaluated by type of infection, hospital site, and presence of infectious diseases (ID) pharmacist on site. Results This study included 119 patients in the pre-ASO group and 121 patients in the post-ASO group. ASO shortened sum length of therapy (LOT) (12 days vs 11 days respectively; p=0.0364) and sum DOT (15 days vs 12 days respectively; p=0.022). This finding appears to be driven by a decrease in outpatient LOT (p=0.0017) and outpatient DOT (p=0.0034). Conversely, ASO extended empiric IV LOT (p=0.005). All other secondary outcomes were not significant. Ten patients missed doses of antimicrobials due to ASO. Subgroup analyses suggested that one hospital may have influenced outcomes and reduction in LOT was observed primarily in sites without an ID pharmacist on site (p=0.018). Conclusion While implementation of ASO decreases sum length of inpatient and outpatient therapy, it may not influence inpatient length of therapy alone. Moreover, ASOs prolong use of empiric intravenous therapy. Hospitals without an ID pharmacist may benefit most from ASO protocols. Disclosures All Authors: No reported disclosures

Background: Antibiotic overuse contributes to antibiotic resistance and unnecessary adverse drug effects. Antibiotic stewardship interventions have primarily focused on acute-care settings. Most antibiotic use, however, occurs in outpatients with acute respiratory tract infections such as pharyngitis. The electronic health record (EHR) might provide an effective and efficient tool for outpatient antibiotic stewardship. We aimed to develop and validate an electronic algorithm to identify inappropriate antibiotic use for pediatric outpatients with pharyngitis. Methods: This study was conducted within the Children’s Hospital of Philadelphia (CHOP) Care Network, including 31 pediatric primary care practices and 3 urgent care centers with a shared EHR serving >250,000 children. We used International Classification of Diseases, Tenth Revision (ICD-10) codes to identify encounters for pharyngitis at any CHOP practice from March 15, 2017, to March 14, 2018, excluding those with concurrent infections (eg, otitis media, sinusitis), immunocompromising conditions, or other comorbidities that might influence the need for antibiotics. We randomly selected 450 features for detailed chart abstraction assessing patient demographics as well as practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for evaluating the electronic algorithm. Criteria for appropriate use included streptococcal testing, use of penicillin or amoxicillin (absent β-lactam allergy), and a 10-day duration of therapy. Results: In 450 patients, the median age was 8.4 years (IQR, 5.5–9.0) and 54% were women. On chart review, 149 patients (33%) received an antibiotic, of whom 126 had a positive rapid strep result. Thus, based on chart review, 23 subjects (5%) diagnosed with pharyngitis received antibiotics inappropriately. Amoxicillin or penicillin was prescribed for 100 of the 126 children (79%) with a positive rapid strep test. Of the 126 children with a positive test, 114 (90%) received the correct antibiotic: amoxicillin, penicillin, or an appropriate alternative antibiotic due to b-lactam allergy. Duration of treatment was correct for all 126 children. Using the electronic algorithm, the proportion of inappropriate prescribing was 28 of 450 (6%). The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were sensitivity (99%, 422 of 427); specificity (100%, 23 of 23); positive predictive value (82%, 23 of 28); and negative predictive value (100%, 422 of 422). Conclusions: For children with pharyngitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. Future work should validate this approach in other settings and develop and evaluate the impact of an audit and feedback intervention based on this tool.Funding: NoneDisclosures: None

Abstract Background In China, the primary health care (PHC) system has been designated responsible for control and prevention of COVID-19, but not treatment. Suspected COVID-19 cases presenting to PHC facilities must be transferred to specialist fever clinics. This study aims to understand the impact of COVID-19 on PHC delivery and on antibiotic prescribing at a community level in rural areas of central China. Methods Qualitative semi-structured interviews were conducted with 18 PHC practitioners and seven patients recruited from two township health centres and nine village clinics in two rural residential areas of Anhui province. Interviews were transcribed verbatim and analysed thematically. Results PHC practitioners reported a major shift in their work away from seeing and treating patients (due to government-mandated referral to specialist Covid clinics) to focus on the key public health roles of tracing, screening and educating in rural areas. The additional work, risk, and financial pressure that PHC practitioners faced, placed considerable strain on them, particularly those working in village clinics. Face to face PHC provision was reduced and there was no substitution with consultations by phone or app, which practitioners attributed to the fact that most of their patients were elderly and not willing or able to switch. Practitioners saw COVID-19 as outside of their area of expertise and very different to the non-COVID-19 respiratory tract infections that they frequently treated pre-pandemic. They reported that antibiotic prescribing was reduced overall because far fewer patients were attending rural PHC facilities, but otherwise their antibiotic prescribing practices remained unchanged. Conclusions The COVID-19 pandemic had considerable impact on PHC in rural China. Practitioners took on substantial additional workload as part of epidemic control and fewer patients were seen in PHC. The reduction in patients seen and treated in PHC led to a reduction in antibiotic prescribing, although clinical practice remains unchanged. Since COVID-19 epidemic control work has been designated as a long-term task in China, rural PHC clinics now face the challenge of how to balance their principal clinical and increased public health roles and, in the case of the village clinics, remain financially viable.

Abstract Background In 2011, The Infectious Diseases Society of America released a clinical practice guideline (CPG) that recommended short-course antibiotic therapy and avoidance of fluoroquinolones for uncomplicated urinary tract infections (UTIs). Recommendations from this CPG were rapidly disseminated to clinicians via review articles, UpToDate, and the Centers for Disease Control and Prevention website; however, it is unclear if this CPG had an impact on national antibiotic prescribing practices. Methods We performed a retrospective cohort study of outpatient and emergency department visits within a commercial insurance database between January 1, 2009, and December 31, 2013. We included nonpregnant women aged 18–44 years who had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a UTI with a concurrent antibiotic prescription. We performed interrupted time series analyses to determine the impact of the CPG on the appropriateness of the antibiotic agent and duration. Results We identified 654 432 women diagnosed with UTI. The patient population was young (mean age, 31 years) and had few comorbidities. Fluoroquinolones, nonfirstline agents, were the most commonly prescribed antibiotic class both before and after release of the guidelines (45% vs 42%). Wide variation was observed in the duration of treatment, with &gt;75% of prescriptions written for nonrecommended treatment durations. The CPG had minimal impact on antibiotic prescribing behavior by providers. Conclusions Inappropriate antibiotic prescribing is common for the treatment of UTIs. The CPG was not associated with a clinically meaningful change in national antibiotic prescribing practices for UTIs. Further interventions are necessary to improve outpatient antibiotic prescribing for UTIs.

Abstract Background In an effort to minimize complications associated with over-utilization of antibiotics, many antimicrobial stewardship programs have incorporated an antibiotic time out (ATO). Despite the increasing adoption of the ATO, limited data are available to support its effectiveness. This study was designed to assess the impact of an automated ATO integrated into the electronic medical record (EMR) on the rate of antibiotic modification in patients receiving broad-spectrum antibiotic(s) for Gram-negative bacteremia (GNB). Methods This was a single-center retrospective cohort study of inpatients from January 2017 to June 2018 conducted at a large academic medical center. ATO was implemented on October 31, 2017. Adult patients with GNB who received at least 72 hours of a systemic antibiotic were included. Patients with neutropenia or polymicrobial infections were excluded. The primary outcome was the proportion of patients who received a modification of therapy within 24 hours of final culture results. Secondary outcomes included modification at any point in therapy, time to modification of therapy, time to de-escalation, and days of therapy of broad-spectrum antibiotics. Results There was a total of 88 patients who met inclusion criteria, 37 patients pre-ATO and 51 patients post-ATO. The primary outcome of modification of therapy within 24 hours of final culture results was not significantly different for patients in the pre-ATO and post-ATO groups (19% vs. 20%, P = 0.94, respectively). The secondary outcome of modification of therapy at any point in therapy was not significantly different between the two groups (62% vs. 66%, P = 0.67). Of the 47 patients who received a modification of therapy, the mean time to modification was significantly shorter in the post-ATO group (52.8 hours vs. 45.26 hours, P < 0.05,). All other secondary outcomes were not significantly different between study groups. Conclusion The ATO alert was not associated with a higher rate of antibiotic modification within 24 hours of culture results in patients with GNB, although there was a significant reduction in the time to antibiotic modification. Further efforts are needed to improve the time to modification and optimize antibiotic prescribing practices. Disclosures All authors: No reported disclosures.

Abstract Background Unnecessary antibiotic prescription to patients with upper respiratory tract infections (URTIs) has led to the increase in antibiotics resistant bacteria rates. In this study, we evaluated the diagnostic accuracy of QuickVue® Dipstick Strep A test (QV-SAT) in children presenting with acute pharyngotonsillitis and its effect on antibiotic prescribing. Methods A single-gated diagnostic accuracy study of children with fever, runny nose, and tonsillitis presenting to a paediatric clinic between March 2016 and September 2018. Paired throat swabs for QV-SAT and culture were collected. None of the children received antibiotics prior to sample collection. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the test were calculated. Results Two hundred four children were included in this study. 111 (54.4%) were boys and 146 (71.6%) were under the age of 5 years. QV-SAT was positive in 44 (21.6%) and throat culture was positive for Group A β- haemolytic Streptococcus (GAS) in 42 (20.6%) of the children. The results of QV-SAT were highly consistent with culture results: only 2 (0.9%) children with negative results had a positive throat culture. The sensitivity of the QV-SAT in the identification of GAS infection was 100% (95% CI 91.6%, 100%) and the NPV was 100% (95% CI 99.9%, 100%). Only 42 children ( 20.6%) were given antibiotics, while 162 (79.4%) were not. Conclusion The QV-SAT is a quick and reliable test that can help dramatically reduce antibiotic prescriptions to children presenting with fever and acute pharyngotonsillitis.

Abstract Background Self-medication with antibiotics (SMA) is one of the most dangerous inappropriate antibiotic use behaviors. This study aims to investigate the impact of parental SMA for children before a consultation on their doctor’s subsequent antibiotic prescribing behavior, including intravenous (IV) antibiotic use in the clinical setting of China. Methods A cross-sectional survey was conducted between June 2017 and April 2018 in three provinces of China. A total of 9526 parents with children aged 0–13 years were investigated. Data from 1275 parents who had self-medicated their children and then visited a doctor in the past month were extracted and analyzed. Results One-third (410) of the studied children had parental SMA before the consultation and 83.9% of them were subsequently prescribed antibiotics by doctors. Children with parental SMA were more likely to be prescribed antibiotics (aOR = 7.79, 95% CI [5.74–10.58]), including IV antibiotics (aOR = 3.05, 95% CI [2.27–4.11]), and both oral and IV antibiotics (aOR = 3.42, 95% CI [2.42–4.84]), than children without parental SMA. Parents with SMA behaviors were more likely to request antibiotics (aOR = 4.05, 95% CI [2.59–6.31]) including IV antibiotics (aOR = 2.58, 95% CI [1.40–4.76]), and be fulfilled by doctors (aOR = 3.22, 95% CI [1.20–8.63]). Conclusions Tailored health education for parents is required in both community and clinical settings to discourage parental SMA for children. The doctors should not prescribe unnecessary antibiotics to reinforce parents’ SMA behaviors. We recommend expanding the current IV antibiotics ban in outpatient settings of China to cover outpatient pediatrics.
