Abstract Background Following updates to IDSA guidelines in 2019, Hartford HealthCare implemented changes to the community acquired pneumonia (CAP) order-set in August 2020 to reflect criteria for 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 CAP from 9/1/19 to 10/31/19 (pre-intervention) and 9/1/20 to 10/31/20 (post-intervention). Patients were identified using ICD-10 codes indicating lower respiratory tract infection and excluded if had a positive SARS-COV-2 PCR during admission. 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 groups, 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< 0.001). 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 = 0.003). There were no differences in order set usage (10% vs. 11.3%, p = 0.642) between the pre- and post-intervention groups, respectively. Hospital LOS was lower 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 Despite low utilization of the order-set, education surrounding order-set changes appeared to improve antibiotic prescribing and hospital LOS in our population. Further opportunities to improve order-set use and thus further increase guideline-concordant therapy are still available. Disclosures Joseph L.

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.

Background: Acute bacterial skin and skin structure infections (ABSSSI) are a leading cause of hospitalization, but are often treated inappropriately in the inpatient setting. A multifaceted stewardship intervention was implemented to encourage prescribing of guideline-concordant therapy (GCT). Objective: To examine the impact of this initiative on antimicrobial prescribing practices and patient outcomes. Methods: This was a single-center, retrospective study of adult inpatients admitted with a primary or secondary diagnosis of ABSSSI, classified by type and severity based on signs of systemic infection. Patients treated during the pre-intervention period (pre-IP) were compared with patients treated during the post-intervention period (post-IP). The primary endpoint was receipt of GCT. Secondary endpoints included receipt of anti-anaerobic antibiotic (AAA) or broad-spectrum antibiotics (BSA). Results: A total of 125 patients were included, 64 in the pre-IP and 61 in the post-IP. There was a statistically significant increase in prescribing of GCT during the post-IP compared with the pre-IP (14% versus 56%, p < 0.0001) and a decrease in use of AAA (56% versus 34%, p = 0.01). No difference was observed with use of BSA (16% versus 15%, p = 0.89). Use of the computerized order set during the post-IP was low (18%). There was a numerical, but non-significant reduction in 30-day readmission (14.1% versus 6.6%, p = 0.17). Conclusion: The multifaceted intervention was effective for improving prescribing of GCT for ABSSSI. Given low use of the computerized order set, improved prescribing seemed to be driven by provider education. Strategies around ongoing education may be key to sustain positive results of stewardship interventions.

Abstract Background Community-acquired pneumonia (CAP) in infancy (i.e., among children aged &lt; 2 years) may have long-term consequences for the rapidly developing lung. We examined the impact of pneumonia in infancy on subsequent respiratory health. Methods A retrospective matched-cohort design and data from Optum’s de-identified Integrated Claims-Clinical dataset (2009-2018) were employed. Study population comprised children who were hospitalized for CAP before age 2 years (“CAP patients”) as well as matched comparators without evidence of pneumonia before age 2 years (“comparison patients”). CAP patients and comparison patients were matched (fixed 1:5 ratio, without replacement) using estimated propensity scores and a nearest-neighbor approach; those with evidence of selected medical conditions (e.g., extreme prematurity, congenital diseases, respiratory diseases) before age 2 years were excluded. Study outcomes included recurrent pneumonia and a composite of asthma, recurrent wheezing, and hyperactive airway disease. Rates of study outcomes from age 2 to 5 years were estimated for all CAP and comparison patients as well as subgroups of CAP patients (and corresponding comparison patients) stratified by etiology (bacterial, viral, unspecified). Results Study population totaled 1,343 CAP patients and 6,715 comparison patients. CAP patients and comparison patients were well-balanced on their baseline characteristics and mean duration of follow-up was 757 and 729 days, respectively. Rates of chronic respiratory disorders from age 2 to 5 years were significantly higher among CAP patients versus comparison patients. Analyses of subgroups stratified by etiology demonstrated higher rates of study outcomes among CAP patients across all strata. Rates of recurrent pneumonia and a composite of asthma, recurrent wheezing, and hyperactive airway disease from age 2 to 5 years among CAP patients and matched comparison patients Conclusion Infant CAP foreshadows an increase in subsequent risk of chronic respiratory disorders. Further studies are needed to determine whether this elevated risk is due to infant pneumonia or whether infant pneumonia is a marker of at-risk children. Disclosures Stephen I.

Abstract Background Ceftriaxone and azithromycin are common empiric antibiotics for community-acquired pneumonia (CAP). Despite low suspicion for atypical infection, azithromycin is often continued for a full course. Negative laboratory data for atypical bacteria may assist with azithromycin de-escalation. Thus, a pharmacist-driven azithromycin de-escalation protocol was implemented for immunocompetent, non-intensive care unit (ICU) patients treated for CAP. The primary outcome was to compare azithromycin duration before and after protocol implementation. Secondary outcomes included hospital length of stay (LOS) and all-cause 30-day readmission. Methods This was a single-center, quasi-experimental study of hospitalized, non-ICU patients treated with azithromycin and a beta-lactam for CAP. The pre- and post-intervention cohorts were from 07/01/2018–04/30/2019 and 07/01/2019–04/30/2020, respectively. Patients were included if they were ≥18 years old, diagnosed with CAP, and had a negative Legionella pneumophila urinary antigen and negative nasopharyngeal swab PCR for Mycoplasma pneumoniae and Chlamydia pneumoniae. Patients were excluded if they were immunocompromised, admitted to an ICU, prescribed azithromycin for an alternative indication, or had evidence of atypical bacteria. Results After exclusion criteria were applied, 90 and 100 patients were included in the pre- and post-intervention cohorts, respectively. Demographic and clinical characteristics were mostly similar between cohorts. This initiative was associated with a statistically significant decrease in azithromycin duration (2 days (IQR 1–2.75) vs. 5 days (IQR 3–6), p &lt; 0.001) and hospital LOS (3 days (IQR 2–5) vs. 5 days (IQR 3–8.25), p &lt; 0.001). No statistically significant difference was observed for all-cause 30-day readmission (14 days (15.6%) vs 13 days (13.0%), p=0.614). Conclusion Implementation of a pharmacist-driven azithromycin de-escalation protocol for CAP was associated with reduced azithromycin duration and hospital LOS, but not all-cause 30-day readmission.

Abstract Background Overutilization of urine cultures may lead to inappropriate use of antibiotics. We implemented a computerized urine culture order set where urine specimens are not processed for culture unless there is evidence of pyuria (≥10 WBC per high power field) on urinalysis (UA), or if a patient is pregnant, neutropenic, neonate, renal transplant recipient, planned for or had a recent urologic procedure. Here we evaluated the impact of this order set on antibiotic utilization, urine culture volumes and rates of catheter-associated urinary tract infections (CAUTI). Methods We performed a retrospective chart review before and after the order set implementation (August–December 2017 and 2018, respectively). The analysis had two distinct components: first was at institution-level, where data for all adult and pediatric inpatients were compared for urine culture volumes and antibiotic use regardless of indication. The second component was done at patient-level, where we compared clinical data and days of therapy (DOT) for all adult inpatients who had urine cultures without pyuria in the specified pre-intervention period, and those with canceled urine cultures due to absence of pyuria post-intervention. Results At the institution-level analysis, a statistically significant reduction was observed in rates of urine cultures performed (P = 0.02), as well as use of penicillins, carbapenems and Trimethoprim-Sulfamethoxazole (TMP-SMX) (P < 0.05). However, the use of cephalosporins has increased post-intervention (P < 0.001). No significant change was noted for aminoglycosides or fluoroquinolones. At the patient-level analysis, DOT means in patients with negative pyuria did not change significantly (5.16 pre-intervention, 6.54 post-intervention, P = 0.202). Prevalence of treatment for bacteriuria despite absence of pyuria was 5.3% (20/380) pre-intervention, vs. 1.9% (1/53) post-intervention (P = 0.494). In the pre-intervention period, three cases met the criteria for CAUTI despite negative pyuria. This misdiagnosis could have been avoided by implementation of the urine culture order set. Conclusion Implementation of a urine culture order set in our institution led to a statistically significant reduction in rates of urine cultures performed, as well as use of penicillins, carbapenems and TMP-SMX.

Abstract Background C-itra is the drug of choice for treatment of most non-CNS, non-life-threatening forms of endemic mycoses (EM), including histoplasmosis, blastomycosis, coccidioidomycosis, sporotrichosis and talaromycosis. SUBA represents a new formulation of itraconazole that utilizes nanotechnology to improve bioavailability when administered orally. SUBA is formulated as nanoparticles allowing for absorption in the small bowel while not relying on gastric acidity for optimal absorption. MSG-15 is an open-label, comparative clinical trial comparing SUBA to c-itra for the treatment of EM. Herein we report the final PK and AE profiles of these two compounds. Methods Subjects with proven and probable EM were eligible this open-label comparative study. The protocol allowed up to 14 d of prior therapy with any antifungal for this episode of EM. Subjects were randomized to receive either SUBA 130 mg po bid or c-itra 200 mg po bid for up to 6 months. Follow up occurred at 7, 14, 28, 42, 84 and 180 d post-enrollment. PK samples were obtained at 7, 14, and 42 d. Clinical assessment, including symptom assessment, AEs, overall drug tolerance, and quality of life were assessed at each visit. We used descriptive statistics for this analysis. Results 89 subjects with EM entered the trial, including 43 on SUBA and 46 on c-itra. We measured PK serum levels of itra and hydroxyl-itra at days 7, 14, and 42 and these data are depicted in Figures 1-3. There were no significant differences in these levels, including combined itra/hydroxyl-itra levels, among the two study arms. AUC for itra and hydroxyl-itra were similar for both arms. AEs as assessed at each study evaluation were also quite similar among the two study arms. Overall, any AE occurred in 74% vs 85% of SUBA and c-itra recipients, respectively (NS). Drug-related AEs occurred in 35% vs 41% of SUBA and itra recipients, respectively (NS). Most common drug-related AEs included cardiovascular (edema and hypertension), nausea and loss of appetite. Combined Itraconazole and Hydroxy-itraconazole Concentration Over Time Conclusion Compared to c-itra, SUBA demonstrates almost identical serum levels despite being dosed at roughly 60% standard dosing for c-itra (130 mg po bid vs 200 mg po bid). SUBA is slightly better tolerated than c-itra, although the specific AEs are similar. Disclosures Peter G.

Abstract Background Remdesivir (RDV) has been shown to shorten recovery time and was well tolerated in patients with severe COVID-19. Here we report baseline characteristics associated with clinical improvement at day (d) 14. Methods We enrolled hospitalized patients with confirmed SARS-CoV-2 infection, oxygen saturation &gt;94% on room air, and radiological evidence of pneumonia. Patients were randomized 1:1:1 to receive 5d or 10d of intravenous RDV once daily plus standard of care (SoC), or SoC only. For this analysis, patients were followed through discharge, d14, or death. Baseline demographic and disease characteristics associated with clinical improvement in oxygen support (≥2-point improvement on a 7-category ordinal scale ranging from discharge to death) were evaluated using multivariable logistic regression methods. Results 584 patients were randomized and treated (5/10d RDV, n=384; SoC: n=200). 159 (27%) were ≥65y, 227 (39%) female, 328 (61%) white, 102 (19%) Asian, and 99 (19%) Black. 252 participants (43%) were enrolled in Europe, 260 (45%) North America (NA), and 72 (12%) in Asia. Most patients (483 [83%]) were not on supplemental oxygen but required medical care at baseline. In a multivariable model, 5/10d RDV was significantly positively associated with clinical improvement (adjusted odds ratio [OR] 1.69, 95% CI: 1.08, 2.65; p=0.0226). Significant covariables positively associated with clinical improvement included age &lt; 65y (p&lt; 0.0001) and region of treatment (Europe and NA vs Asia, p&lt; 0.0001 each; Table); other examined factors were not significantly associated with clinical improvement, including gender, race, ethnicity, baseline oxygen support, duration of symptoms and hospitalization, obesity, and baseline transaminase levels. Table 1. Conclusion In moderate COVID-19 patients, after adjusting for treatment arm, age &lt; 65y and region (NA vs Asia; Europe vs Asia) were associated with higher rates of clinical improvement. These observations recapitulate younger age as positive prognostic factor, and highlight the differences in the impact of the pandemic globally.

Abstract Background Acute respiratory tract infections (ARIs) are a significant cause of morbidity in adults. Influenza is associated with about 490,600 hospitalizations and 34,200 deaths in the US in the 2018-2019 season. The burden of rhinovirus among adults hospitalized with ARI is less well known. We compared the burden of influenza and rhinovirus from 2 consecutive winter respiratory viral seasons in hospitalized adults and healthy controls pre-COVID-19 and one season mid-COVID-19 to determine the impact of rhinovirus as a pathogen. Methods From Oct 2018 to Apr 2021, prospective surveillance of adults ≥50 years old admitted with ARI or COPD/CHF exacerbations at any age was conducted at two Atlanta hospitals. Adults were eligible if they lived within an eight-county region around Atlanta and if their symptom duration was &lt; 14 days. In the seasons from Oct 2018 to Mar 2020, asymptomatic adults ≥50 years old were enrolled as controls. Standard of care test results were included and those enrolled contributed nasopharyngeal swabs that were tested for respiratory pathogens using BioFire® FilmArray® Respiratory Viral Panel (RVP). Results During the first two seasons, 1566 hospitalized adults were enrolled. Rhinovirus was detected in 7.5% (118) and influenza was detected in 7.7% (121). Rhinovirus was also detected in 2.2% of 466 healthy adult controls while influenza was detected in 0%. During Season 3, the peak of the COVID-19 pandemic, influenza declined to 0% of ARI hospitalizations. Rhinovirus also declined (p=0.01) but still accounted for 5.1% of all ARIs screened (Figure 1). Rhinovirus was detected at a greater rate in Season 3 than in asymptomatic controls in the first 2 seasons (p=0.008). In the first two seasons, Influenza was detected in 8.6% (24/276) of those admitted to the ICU. Rhinovirus was detected in 6.1% (17/276) of those admitted to the ICU but declined to 3.1% (8/258) in Season 3. Figure 1. Percent Positive Cases of Influenza and Rhinovirus between Season 1&2 (hospitalized and healthy controls) vs Season 3 (hospitalized) Conclusion Dramatic declines occurred in influenza in adults hospitalized with ARI, CHF, or COPD in Atlanta during the COVID-19 pandemic and with enhanced public health measures. Although rhinovirus declined during the COVID-19 pandemic, it continued to be identified at a rate higher than in historical controls. Additional data are needed to understand the role of rhinovirus in adult ARI, CHF, and COPD exacerbations. Disclosures David L. Swerdlow, MD, Pfizer Vaccines (Employee) Robin Hubler, MS, Pfizer Inc.

Abstract Background A significant burden of disease exists for adults infected with influenza (flu) and SARS-CoV-2, which causes COVID-19. However, data are limited comparing outcomes between hospitalized adults infected with these viruses. Methods Over the course of 3 consecutive winter respiratory viral seasons, adults ≥ 50 years of age admitted with acute respiratory tract infections (ARI) and adults of any age with COPD or CHF-related admissions were enrolled from 2 Atlanta area hospitals. For the 2018-19 and 2019-20 seasons, participants were approached in the hospital. If the participant enrolled, nasopharyngeal (NP) and oropharyngeal (OP) swabs were collected and tested using BioFire® FilmArray® respiratory panel. Due to the COVID-19 pandemic in 2020-21 and limitations involving participant contact, only NP standard of care (SOC) swabs were collected. A comprehensive medical chart review was completed for each subject which encompassed data on their hospitalization, past medical history, and vaccination history. Co-infected patients were excluded from the analyses. Results Of the eligible participants, 118 were flu positive (three RSV-influenza co-infections were excluded) and 527 were COVID-19 positive. Median age was lower for the flu cohort at 62 (IQR 56-71) than those with COVID-19 (67, IQR 59-77) (p &lt; 0.0001). Length of stay (LOS) was shorter in flu-infected patients (median 3 d, IQR 2-6), but was longer for COVID-19 patients (median 5 d, IQR 3-10). ICU admission occurred in 20% of those with flu, and among those admitted to the ICU mechanical ventilation (MV) occurred in 12.5%. ICU admission and MV was significantly higher for those with COVID-19, with 28% of patients admitted to the ICU and 47% of those requiring MV. Among patients with COVID-19, 8.9% died. This was significantly higher than that of flu (3.4%) (p=0.008). Hospital discharge occurred more frequently to a nursing home or LTCF with COVID-19 (10.3%) than with flu (0%) (p&lt; 0.0001). Table 1. Breakdown of age, hospitalization course, and discharge disposition for participants diagnosed with influenza or COVID-19 during hospitalization. Conclusion COVID-19 resulted in a longer hospital admission, a greater chance of ICU admission and MV as compared to flu. Additionally, COVID-19 participants had a high rate of discharge to a nursing home/LTCF and a significantly higher risk of death. While the clinical course was not as severe as COVID-19, influenza contributed a significant burden. Disclosures David L. Swerdlow, MD, Pfizer Vaccines (Employee) Robin Hubler, MS, Pfizer Inc.
