138. Implementation of an Antimicrobial Stewardship Order Set in the Emergency Department at a Quaternary Care Facility

BackgroundImplementation of antimicrobial stewardship (AS) interventions in the emergency department (ED) has been associated with improved patient outcomes. One potentially promising AS strategy is the implementation of an ED-specific, evidence-based antimicrobial order set. In this study, we aimed to examine the impact of implementing an ED-specific order set (EDOS) on the appropriateness of empiric antimicrobial therapy.MethodsWe conducted a pre-post quasi experimental study on 160 adult patients presenting to the ED with suspected or confirmed common infections at our quaternary healthcare facility. The EDOS was implemented in December 2020, providing evidence-based recommendations for the management of common infectious diseases. Data was collected between September 2019 and March 2020 for the pre-EDOS implementation group and between January 2021 and April 2021 for the post-EDOS implementation group.Pregnant women and patients with suspected or confirmed COVID-19 infection were excluded. Data were analyzed using two-sample T-test and mixed effects logistic regression. The primary study outcome was the appropriateness of antimicrobials selected, and the secondary outcomes were clinical and microbiologic cure, length of hospital stay, Clostridioides difficile infection, and the number of changes in antimicrobial therapy on transition to inpatient setting.ResultsA total of 100 ED patients pre-EDOS implementation and 60 patients post-EDOS implementation were compared. At baseline, patients in the post-EDOS group were older (59.83±20.30 years vs. 50.17±19.97 years, P=0.0037). A higher number of patients in the post-EDOS group had a history of multiple comorbidities (76.67% vs. 54%, P=0.0039). There was a higher rate of appropriate antimicrobial use in the post-EDOS group as compared to the pre-EDOS group (88.3% vs. 50%, P< 0.001). Longer hospital stays were observed in the post-EDOS group (P=0.0005). Clinical cure was similar between the two groups (96.6% vs. 94%, P=0.4568). ConclusionIn our study, we observed higher rates of appropriate antimicrobial selection after implementation of an EDOS. Use of an EDOS may represent a valuable AS intervention to guide appropriate antimicrobial prescribing in the ED, and larger studies are needed to confirm those findings.Disclosures All Authors: No reported disclosures

B-02 Neuropsychological Deficits Following Right Hemisphere Cerebrovascular Accidents in a Patient with Human Immunodeficiency Virus, Hepatitis C, and Polysubstance Abuse

Abstract Objective In right hemisphere cerebrovascular accident (CVA), expected deficits might include inattention syndromes, visuospatial impairment, or neglect. This case study adds to the literature by presenting neuropsychological data from a patient with a complex medical history who experienced two right hemisphere CVAs. The aim is to demonstrate that neuropsychological deficits following CVA may not be as expected in patients with comorbidities, and to highlight the importance of neuropsychological assessment in such cases. Method The patient is a 69-year-old, right-handed, African American man who presented with reading and memory difficulties, problems recognizing faces, and vision impairment following right occipital and temporoparietal ischemic CVAs. Comprehensive neuropsychological evaluation was conducted. Formal measures were utilized, but the examiners were also required to devise appropriate bedside measures. Results The patient had difficulty recognizing his caregiver’s face. He could not identify facial expressions made by examiners, but commented on individual facial features. Design copies were distorted/fragmented, and he evidenced difficulty integrating visual components into a whole. He also demonstrated spelling and verbal memory impairment (BDAE Oral Spelling raw = 0; HVLT-R recall and recognition &lt; 1st percentile). Full results are included in a supplemental data table. Conclusions Results were strongly suggestive of simultanagnosia, though this disorder typically results from bilateral parietal-occipital lesions. Additionally, the neuropsychological impairments noted extended beyond those typical of right hemisphere CVA, likely related to the patient’s history of multiple comorbidities (e.g., infectious disease, polysubstance abuse). This case highlights the importance of neuropsychological assessment in the care of medically complex patients, and the unique ability of neuropsychologists to conduct such evaluations.
