Abstract Background AmpC beta-lactamase producing organisms are traditionally treated with carbapenem or fluoroquinolone antibiotics. Recent studies, however, describe similar clinical outcomes in patients that receive cefepime or piperacillin/tazobactam. We sought to assess outcomes in patients with bloodstream infections caused by AmpC-producing organisms that received beta-lactams compared non-beta-lactam therapy. Methods Data was obtained retrospectively from the electronic health record (EHR) from January 2012 to February 2020. The primary objective was 30-day mortality from the day of first positive blood cultures with Enterobacter spp., Citrobacter spp., or Serratia spp. in patients who received non-beta-lactam therapy (carbapenem, fluoroquinolone, trimethoprim/sulfamethoxazole) to those who received beta-lactam therapy (cefepime, piperacillin/tazobactam). Secondary objectives included 30-day recurrence of bacteremia, pathogen isolated, source of bacteremia, hospital length of stay, and duration of antimicrobial therapy. Results A total of 90 patients were included, 50 in the non-beta lactam group and 40 in the beta-lactam group. Demographics were similar between groups. Thirty-day mortality was significantly higher in the beta-lactam group (20% vs 2%, p=0.009). Enterobacter spp. was the most frequently identified pathogen (67%), most commonly isolated from a urinary (31%) or intra-abdominal source (22%). The average duration of antibiotic therapy was significantly higher in the non-beta lactam group (18 vs 12 days, p=0.001). In contrast, there was no significant difference found in hospital length of stay, recurrence of bacteremia, pathogen isolated or source of bacteremia between groups. Conclusion Beta-lactam therapy for the treatment of bloodstream infections caused by Amp-C producing organisms was associated with significantly greater 30-day mortality compared to patients that received non-beta-lactam therapy.

232 Background: Traditionally, hospital units function as multidisciplinary teams which work in silos and communicate via notes in the Electronic Health System. This often leads to communication breakdown, frequently translating to adverse clinical outcomes and prolonged hospital length of stay. Our primary objective was to introduce Inter-Professional Team (IPT) rounds on the oncology unit and evaluate the impact on length of stay (LOS) within a Plan, Do, Study, Act (PDSA) cycle. Methods: The care transition team planned the IPT rounds structure and training curriculum which included team goals, post-rounds structure for addressing barriers to care progression, and member roles/scripting. Change in LOS and case mix index (CMI)-adjusted LOS post-IPT round implementation ( Do) in July 2017 was analyzed ( Study) using hierarchical linear models for patients with an admission to the oncology service from September 2016 to March 2018. Beta coefficients (β) and 95% confidence intervals (CI) were estimated and models were adjusted for calendar time. Results: Ten attending medical oncologists participated in IPT round implementation. Of 889 oncology admissions, median LOS and CMI-adjusted LOS pre-IPT round implementation (n = 464) was 4 days (IQR 2-6) and 3 days (IQR 1.8-4.7), while post-IPT round implementation (n = 425) was 4 days (IQR 2-6) and 2.9 days (IQR 1.9-4.4), respectively. Three common reasons for admission were septicemia (n = 96), hematologic complications (n = 42, e.g. anemia/neutropenia), and renal failure (n = 25). Adjusted models for LOS and CMI-adjusted LOS showed no significant difference post-IPT round implementation (β = 0.8 days, 95% CI -0.7-2.3; β = 0.5 days, 95% CI -0.3-1.3, respectively) when compared to pre-implementation. Conclusions: We did not observe decreased LOS in early outcomes. However, IDT rounds built on TEAMSTEPPS 2.0 elements with incorporation of key principles desirable in a patient care team. Next steps include further analysis to better understand cancer stages and diagnoses contributing to longer LOS. We also plan to evaluate patient satisfaction, educational needs, and readmission rates to restructure ( Act) IPT rounds to better serve the needs of our unique patient population.

Objective The primary objective of this study was to identify factors that have predictive value in determining total hospital length of stay in patients with febrile neutropenia, particularly time to first antibiotic dose. Methods This study was a retrospective chart review analyzing patients admitted to a 443 bed tertiary county teaching hospital from 1 November 2010 through 1 November 2015. Patients were eligible for enrollment into the study if they met Infectious Diseases Society of America accepted criteria for febrile neutropenia. Results Ninety-three patients were included for analysis. Time to first antibiotic dose, first empirically appropriate antibiotic dose, and time to first isolate-appropriate antibiotic did not show a significant correlation to total hospital length of stay (p = 0.71, p = 0.342, and p = 0.77, respectively). Subject’s Multinational Association for Supportive Care in Cancer and Simplified Acute Physiology II scores were significantly correlated with hospital lengths of stay (p = 0.0052, rs = −0.243 and p = 0.0001, rs = 0.344, respectively). Higher median (interquartile ranges) Simplified Acute Physiology II scores were also associated with hospital mortality [dead = 46 (34.8–51.7) vs. alive = 34 (28–43.3), p = 0.0173]. Conclusions Measures of patient acuity, such as the Multinational Association for Supportive Care in Cancer and Simplified Acute Physiology II scores, did show a correlation to clinical outcomes in patients with febrile neutropenia. Timing of initial antibiotics between 2.32 and 6.27 hours after presentation in patients with febrile neutropenia did not correlate with clinical outcomes.

OBJECTIVE The pharmacokinetics of beta-lactam antibiotics favor administration via an extended infusion. Although literature supporting extended infusion beta-lactams exists in adults, few data are available to guide the practice in pediatrics. The purpose of this study was to compare clinical outcomes between extended and standard infusions in children. METHODS This retrospective chart analysis included hospitalized patients 0 to 18 years old who received at least 72 hours of cefepime, piperacillin-tazobactam, or meropenem between October 1, 2017, and March 31, 2019. Clinical outcomes of care included hospital length of stay, readmission within 30 days, and all-cause mortality. RESULTS A total of 551 patients (258 extended infusion, 293 standard infusion) met criteria for evaluation. Clinical outcomes among the entire population were similar. A subanalysis of select populations demonstrated decreased mortality in critical care patients (2.1% vs 19.6%, p = 0.006) and decreased 30-day readmission rates in bone marrow transplant patients (0% vs 50%, p = 0.012) who received the extended infusion compared with a standard infusion. CONCLUSIONS Outcomes were similar between extended and standard infusions in children. Subgroup analyses suggest a possible mortality benefit in the critically ill and decreased readmission rate in bone marrow transplant patients.

Abstract Background Anti-staphylococcal beta-lactams (BL) are treatment of choice for methicillin-susceptible Staphylococcus aureus (MSSA) bloodstream infections (BSI) as they have superior MSSA bacteremia clearance. Based on the hypothesis that earlier initiation of anti-staphylococcal BL may improve clinical outcomes, this study compared clinical and microbiologic features of patients with MSSA BSI pre- and post-implementation of Accelerate Pheno™ (AXDX). Methods This was a case-control analysis of adult inpatients with MSSA BSI analyzed using AXDX compared to traditional laboratory methods. Cases were prospectively identified by the antimicrobial stewardship team between August and October 2020 post implementation of AXDX in July 2020. Patients were matched with historical controls (July 2018–July 2020) based on age (±4 years), gender, organism, and source of infection. The primary outcome was time to antibiotic (abx) deescalation to an anti-staphylococcal beta-lactam. Secondary outcomes included hospital length of stay (LOS), 30-day all-cause mortality and hospital readmission, and 60-day C. difficile infection. Results A total of 25 cases with MSSA BSI were identified, of which 18 (72%) were matched to historical controls. Of these patients, 12 (67%) were male with an average age of 67 years (SD ±12). Other demographics were similar between groups. The median time to species identification [21.3 hours in cases (IQR 14–31.9) vs 33.3 hours in controls (29–41.7), p=0.046] and abx susceptibilities [22.5 hours (18.8 – 42) vs 60.1 hours (46–61.9), p< 0.001] were significantly shorter in cases. The average time to abx deescalation from time to organism susceptibility was 1.7 days (±1.9) for cases compared to 2.7 days (±1.5) for controls (p = 0.129). There were no significant differences detected in hospital LOS, 30-day mortality or readmission, and 60-day C.difficile infection. Conclusion Although time to organism identification and abx susceptibilities was significantly shorter in cases, AXDX was not associated with a statistically significant reduction in time to anti-staphylococcal BL initiation nor a difference in associated clinical outcomes. A trend in shorter time to abx de-escalation was observed and warrants further investigation in a larger population. Disclosures All Authors: No reported disclosures

Objective: Previous studies looking at emergency department (ED) crowding and delays of care on outcome measures for certain medical and surgical patients excluded trauma patients. The objectives of this study were to assess the relationship of trauma patients’ ED length of stay (EDLOS) on hospital length of stay (HLOS) and on mortality; and to examine the association of ED and hospital capacity on EDLOS.Methods: This was a retrospective database review of Level 1 and 2 trauma patients at a single site Level 1 Trauma Center in the Midwest over a one year period. Out of a sample of 1,492, there were 1,207 patients in the analysis after exclusions. The main outcome was the difference in hospital mortality by EDLOS group (short was less than 4 hours vs. long, greater than 4 hours). HLOS was compared by EDLOS group, stratified by Trauma Injury Severity Score (TRISS) category (< 0.5, 0.51-0.89, > 0.9) to describe the association between ED and hospital capacity on EDLOS.Results: There was no significant difference in mortality by EDLOS (4.8% short and 4% long, p = .5). There was no significant difference in HLOS between EDLOS, when adjusted for TRISS. ED census did not affect EDLOS (p = .59), however; EDLOS was longer when the percentage of staffed hospital beds available was lower (p < .001).Conclusions: While hospital overcrowding did increase EDLOS, there was no association between EDLOS and mortality or HLOS in leveled trauma patients at this institution.

Objective We evaluated the effect of chronic use of statins based on C-reactive protein (CRP) levels and hospital length of stay (LOS) in patients admitted with community-acquired pneumonia (CAP). Methods We conducted a retrospective study over 12 months at a teaching hospital in Lebanon comparing patients with CAP taking chronic statins with patients not taking statins. Included patients with CAP were older than age 18 years and had two CRP level measures during hospitalization. CURB-65 criteria were used to assess the severity of pneumonia. A decrease in CRP levels on days 1 and 3, LOS, and normalization of fever were used to assess the response to antibiotics. Results Sixty-one patients were taking statins and 90 patients were not taking statins. Patients on statins had significantly more comorbid conditions; both groups had comparable CURB-65 scores. In both groups, no statistically significant difference was seen for the decrease in CRP level on days 1 and 3 and LOS. No difference in days to normalization of fever was detected in either group. Conclusion No association was found between the chronic use of statins and CRP levels, LOS, or days to fever normalization in patients with CAP.

AbstractPurposeThis small-scale, prospective cohort study nested within a randomized controlled trial aimed to investigate the possible associations between physical activity levels and clinical outcomes among hospitalized patients with severe COVID-19.MethodsHospitalized patients with severe COVID-19 were recruited from Clinical Hospital of the School of Medicine of the University of Sao Paulo (a quaternary referral teaching hospital), and from Ibirapuera Field Hospital, both located in Sao Paulo, Brazil. Physical activity levels were assessed by Baecke Questionnaire of Habitual Physical Activity. The primary outcome was hospital length of stay. The secondary outcomes were: mortality, admission to the intensive care unit (ICU), and mechanical ventilation requirement.ResultsMean hospital length of stay was 8.5 ± 7.1 days; 3.3% of patients died, 13.8% were admitted to ICU, and 8.6% required mechanical ventilation. Linear regression models showed that physical activity indexes were not associated with hospital length of stay (work index: β=-0.57 [95%CI: −1.80 to 0.65], p=0.355; sport index: β=0.43 [95%CI: −0.94 to 1.80], p=0.536; leisure-time index: β=1.18 [95%CI: −0.22 to 2.59], p=0.099; total activity index: β=0.20 [95%CI: −0.48 to 0.87], p=0.563. Physical activity indexes were not associated with mortality, admission to ICU and mechanical ventilation requirement (all p>0.05).ConclusionsAmong hospitalized patients with COVID-19, physical activity did not associate with hospital length of stay or any other clinically-relevant outcomes. These findings suggest that previous physical activity levels may not change the prognosis of severe COVID-19.

Background: National guidelines recommend regular measurement of functional status among patients with cancer, particularly those who are elderly or high-risk, but little is known about how functional status relates to clinical outcomes among hospitalized patients with advanced cancer. The goal of this study was to investigate how functional impairment is associated with symptom burden and healthcare utilization and clinical outcomes. Patients and Methods: We conducted a prospective observational study of patients with advanced cancer with unplanned hospitalizations at Massachusetts General Hospital from September 2014 through March 2016. Upon admission, nurses assessed patients’ activities of daily living (ADLs; mobility, feeding, bathing, dressing, and grooming). Patients with any ADL impairment on admission were classified as having functional impairment. We used the revised Edmonton Symptom Assessment System (ESAS-r) and Patient Health Questionnaire-4 to assess physical and psychological symptoms, respectively. Multivariable regression models were used to assess the relationships between functional impairment, hospital length of stay, and survival. Results: Among 971 patients, 390 (40.2%) had functional impairment. Those with functional impairment were older (mean age, 67.18 vs 60.81 years; P<.001) and had a higher physical symptom burden (mean ESAS physical score, 35.29 vs 30.85; P<.001) compared with those with no functional impairment. They were also more likely to report moderate-to-severe pain (74.9% vs 63.1%; P<.001) and symptoms of depression (38.3% vs 23.6%; P<.001) and anxiety (35.9% vs 22.4%; P<.001). Functional impairment was associated with longer hospital length of stay (β = 1.29; P<.001) and worse survival (hazard ratio, 1.73; P<.001). Conclusions: Hospitalized patients with advanced cancer who had functional impairment experienced a significantly higher symptom burden and worse clinical outcomes compared with those without functional impairment. These findings provide evidence supporting the routine assessment of functional status on hospital admission and using this to inform discharge planning, discussions about prognosis, and the development of interventions addressing patients’ symptoms and physical function.

688 Background: Whether upfront resection or total neoadjuvant therapy is superior for the treatment of potentially resectable pancreatic adenocarcinoma (PDAC) remains controversial. The impact of neoadjuvant treatment on major perioperative complication rates for patients (pts) undergoing resection for PDAC is commonly debated. We hypothesized that rates would be comparable among patients receiving neoadjuvant chemoradiation (neo-CRT), neoadjuvant chemotherapy alone (neo-CHT), or upfront surgery. Methods: This is a retrospective study of 208 pts with PDAC who underwent resection within a multidisciplinary pancreatico-biliary program at an academic tertiary referral center between 2011-2018. Data were abstracted from the medical record, an institutional cancer registry and NSQIP databases. Outcomes were assessed using χ2, Fisher’s exact test and two-tailed Student’s t-tests. Results: 208 pts were identified: 33 locally advanced, borderline or upfront resectable pts underwent neo-CRT, 35 borderline or resectable pts underwent neoadjuvant-CHT, and 140 resectable pts did not undergo neoadjuvant therapy. There were no statistically significant differences in major perioperative complication rates between groups. Overall rates were 36.4%, 34.3%, and 26.4% for pts who underwent neo-CRT, neo-CHT alone, or upfront resection, respectively (p = 0.38). No significant difference were observed in complication rates (35.3% v. 26.4%; p = 0.19) or median hospital length of stay (10 days v. 10 days; p = 0.87) in pts who received any neoadjuvant therapy versus upfront resection. There were two perioperative deaths in the neo-CRT group (6.1%), zero in the neo-CHT group, and four in the upfront resection group (2.9%); p = 0.22. Conclusions: There were no significant differences in major perioperative complication rates, hospital length of stay, or post-operative mortality in pts who underwent neoadjuvant therapy (neo-CRT or neo-CHT alone) versus upfront surgery. Notably, neo-CRT had comparable perioperative complication rates to neo-CHT alone, which suggests neoadjuvant radiation therapy may not pose additional surgical risk.
