Objectives: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a severe subtype of chronic rhinosinusitis that can affect patients despite medical and surgical interventions. The purpose of this study was to utilize the techniques of proteomics to investigate differences in protein abundance within the sinonasal mucosa of patients with CRSwNP compared to healthy controls. Methods: In a case-control study at a tertiary-care academic medical center, sinonasal mucosa was harvested from 3 patients with CRSwNP and 3 control patients undergoing transsphenoidal excision of pituitary tumors. Two-dimensional gel electrophoresis was used to identify proteins with elevated or reduced abundance in CRSwNP patients compared to controls. The proteins showing the greatest abundance differences were characterized by mass spectrometry. Results: More than 300 differentially abundant proteins (p ≤ 0.05) were identified. Many of these protein species were involved in the host inflammatory response. Proteins up-regulated in CRSwNP patients included eosinophil lysophospholipase by a ratio (R) of 18.13, RHO-GDP dissociation inhibitor 2 (R = 2.80), and apolipoprotein A-1 (R = 1.73). Down-regulated proteins in CRSwNP patients included catalase (R = −5.87), annexin A1 (R = −6.27), and keratin II-8 (R = −6.73). A detailed analysis of additional protein species is outlined. Conclusions: The proteomic approach allows detection of significant differences in protein abundance in CRSwNP and provides unique insight into the pathophysiology of this common disease.

Background: As more US hospitals report antibiotic utilization to the CDC, standardized antimicrobial administration ratios (SAARs) derived from patient care unit-based antibiotic utilization data will increasingly be used to guide local antibiotic stewardship interventions. Location-based antibiotic utilization surveillance data are often utilized given the relative ease of ascertainment. However, aggregating antibiotic use data on a unit basis may have variable effects depending on the number of clinical teams providing care. In this study, we examined antibiotic utilization from units at a tertiary-care hospital to illustrate the potential challenges of using unit-based antibiotic utilization to change individual prescribing. Methods: We used inpatient pharmacy antibiotic use administration records at an adult tertiary-care academic medical center over a 6-month period from January 2019 through June 2019 to describe the geographic footprints and AU of medical, surgical, and critical care teams. All teams accounting for at least 1 patient day present on each unit during the study period were included in the analysis, as were all teams prescribing at least 1 antibiotic day of therapy (DOT). Results: The study population consisted of 24 units: 6 ICUs (25%) and 18 non-ICUs (75%). Over the study period, the average numbers of teams caring for patients in ICU and non-ICU wards were 10.2 (range, 3.2–16.9) and 13.7 (range, 10.4–18.9), respectively. Units were divided into 3 categories by the number of teams, accounting for ≥70% of total patient days present (Fig. 1): “homogenous” (≤3), “pauciteam” (4–7 teams), and “heterogeneous” (>7 teams). In total, 12 (50%) units were “pauciteam”; 7 (29%) were “homogeneous”; and 5 (21%) were “heterogeneous.” Units could also be classified as “homogenous,” “pauciteam,” or “heterogeneous” based on team-level antibiotic utilization or DOT for specific antibiotics. Different patterns emerged based on antibiotic restriction status. Classifying units based on vancomycin DOT (unrestricted) exhibited fewer “heterogeneous” units, whereas using meropenem DOT (restricted) revealed no “heterogeneous” units. Furthermore, the average number of units where individual clinical teams prescribed an antibiotic varied widely (range, 1.4–12.3 units per team). Conclusions: Unit-based antibiotic utilization data may encounter limitations in affecting prescriber behavior, particularly on units where a large number of clinical teams contribute to antibiotic utilization. Additionally, some services prescribing antibiotics across many hospital units may be minimally influenced by unit-level data. Team-based antibiotic utilization may allow for a more targeted metric to drive individual team prescribing.Funding: NoneDisclosures: None

Medicinal leech therapy promotes vascular flow and can be used to salvage grafts. Medicinal leeches have a symbiotic relationship with Aeromonas species and can therefore present a risk of bacterial transmission to patients. Antimicrobial prophylaxis is warranted for the duration of leech therapy, however, an institutional evaluation of 40 patients receiving medicinal leech therapy demonstrated poor adherence with recommendations. An electronic medical record order panel for antimicrobial prophylaxis with medicinal leech therapy was implemented, leading to a subsequent improvement in adherence to prophylaxis use, including significant increases in the ordering of antibiotics and the appropriate timing of initiation in the subsequent 10 patients receiving medicinal leech therapy after panel implementation. Aeromonas infections were rare before and after panel implementation, and developed only in the patient subset with non-optimized prophylaxis.

Background: In December of 2019, the World Health Organization reported a novel coronavirus (severe acute respiratory coronavirus virus 2 [SARS-CoV-2)]) causing severe respiratory illness originating in Wuhan, China. Since then, an increasing number of cases and the confirmation of human-to-human transmission has led to the need to develop a communication campaign at our institution. We describe the impact of the communication campaign on the number of calls received and describe patterns of calls during the early stages of our response to this emerging infection. Methods: The University of Iowa Hospitals & Clinics is an 811-bed academic medical center with >200 outpatient clinics. In response to the coronavirus disease 2019 (COVID-19) outbreak, we launched a communications campaign on January 17, 2020. Initial communications included email updates to staff and a dedicated COVID-19 webpage with up-to-date information. Subsequently, we developed an electronic screening tool to guide a risk assessment during patient check in. The screening tool identifies travel to China in the past 14 days and the presence of symptoms defined as fever >37.7°C plus cough or difficulty breathing. The screening tool was activated on January 24, 2020. In addition, university staff contacted each student whose primary residence record included Hubei Province, China. Students were provided with medical contact information, signs and symptoms to monitor for, and a thermometer. Results: During the first 5 days of the campaign, 3 calls were related to COVID-19. The number of calls increased to 18 in the 5 days following the implementation of the electronic screening tool. Of the 21 calls received to date, 8 calls (38%) were generated due to the electronic travel screen, 4 calls (19%) were due to a positive coronavirus result in a multiplex respiratory panel, 4 calls (19%) were related to provider assessment only (without an electronic screening trigger), and 2 calls (10%) sought additional information following the viewing of the web-based communication campaign. Moreover, 3 calls (14%) were for people without travel history but with respiratory symptoms and contact with a person with recent travel to China. Among those reporting symptoms after travel to China, mean time since arrival to the United States was 2.7 days (range, 0–11 days). Conclusion: The COVID-19 outbreak is evolving, and providing up to date information is challenging. Implementing an electronic screening tool helped providers assess patients and direct questions to infection prevention professionals. Analyzing the types of calls received helped tailor messaging to frontline staff.Funding: NoneDisclosures: None

Abstract Background Healthcare workers have experienced a significant burden of COVID-19 disease. COVID mRNA vaccines have shown great efficacy in prevention of severe disease and hospitalization due to COVID infection, but limited data is available about acquisition of infection and asymptomatic viral shedding. Methods Fully vaccinated healthcare workers at a tertiary-care academic medical center in Omaha Nebraska who reported a household exposure to COVID-19 infection are eligible for a screening program in which they are serially screened with PCR but allowed to work if negative on initial test and asymptomatic. Serial screening by NP swab was completed every 5-7 days, and workers became excluded from work if testing was positive or became symptomatic. Results Of the 94 employees who were fully vaccinated at the time of the household exposure to COVID-19 infection, 78 completed serial testing and were negative. Sixteen were positive on initial or subsequent screening. Vaccine failure rate of 17.0% (16/94). Healthcare workers exposed to household COVID positive contact Conclusion High risk household exposures to COVID-19 infection remains a significant potential source of infections in healthcare workers even after workers are fully vaccinated with COVID mRNA vaccines especially those with contact to positive domestic partners.

Purpose: Traditionally, the morbidity and mortality conference (M&MC) is a forum where possible medical errors are discussed. Although M&MCs can facilitate identification of opportunities for systemwide improvements, few studies have described their use for this purpose, particularly in residency training programs. This paper describes the use of M&MC case review as a quality improvement activity that teaches system-based practice and can engage residents in improving systems of care. Methods: Internal medicine residents at a tertiary care academic medical center reviewed 347 consecutive mortalities from March 2014 to September 2017. The residents used case review worksheets to categorize and track causes of mortality, and then debriefed with a faculty member. Selected cases were then presented at a larger interdepartmental meeting and action items were implemented. Descriptive statistics and thematic analysis were used to analyze the results. Results: The residents identified a possible diagnostic mismatch at some point from admission to death in 54.5% of cases (n= 189) and a possible need for improved management in 48.0% of cases. Three possible management failure themes were identified, including failure to plan, failure to communicate, and failure to rescue, which accounted for 21.9%, 10.7 %, and 10.1% of cases, respectively. Following these reviews, quality improvement initiatives proposed by residents led to system-based changes. Conclusion: A resident-driven mortality review curriculum can lead to improvements in systems of care. This novel type of curriculum can be used to teach system-based practice. The recruitment of teaching faculty with expertise in quality improvement and mortality case analyses is essential for such a project.

BACKGROUND: Advance directives are a means of promoting patient autonomy in end-of-life decisions but are used infrequently. A recent federal law requires healthcare organizations to provide information to patients about advance directives. This study explored attitudes and behaviors related to the use of advance directives in three areas: familiarity with advance directives, reasons for completing or not completing advance directives and preferences for receiving information about advance directives. METHODS: A questionnaire was administered by personal interview to a nonrandomized convenience sample of 46 inpatients and 50 outpatients at a large, tertiary care, urban academic medical center in the summer of 1991. RESULTS: Most respondents (77%) had heard of either the living will or durable power of attorney for healthcare, but only 52% correctly understood the purpose of these documents. Twenty-nine percent of the sample had executed an advance directive. Those who had advance directives were older and considered themselves less healthy than did those without advance directives. Unfamiliarity with advance directives and procrastination were cited most often as reasons for not having an advance directive. Most subjects (65%) had spoken with someone, usually a family member or close friend, about preferences for treatment during a critical illness. Although they had rarely discussed advance directives, 83% anticipated that they would be comfortable doing so with a physician or a nurse. CONCLUSIONS: Advance directives are used infrequently to document treatment preferences. The success of programs to promote greater use of advance directives depends on a clearer understanding of the factors that influence both decision and action to execute an advance directive. Patients claim to be comfortable in discussing the topic and prefer that such discussions occur in the outpatient setting.

Abstract Background The University of Minnesota Medical Center (UMMC) is a tertiary care facility, which has had a comprehensive antimicrobial stewardship program (ASP) for 12 years. Methods The antimicrobial stewardship team is comprised of a full-time PharmD and ID staff physicians. Recommendations are placed in the electronic medical record as a progress note. Verbal recommendations may also be made. Results There was a downward trend in Hospital-acquired (HA) C. difficile diarrhea from 2007 to 2014 from 1.2 to 0.5/1000 patient-days (pt day). Rates appear stable from 2014 to 2019 with adjustment for change to NHSN lab-based CDI surveillance (Figure 1). From 2009 to 2019 a decrease was seen in VRE hospital-acquired infections (HAI) from 0.53 to 0.21/1,000 patient-days and in MRSA HAIs from 0.2 to 0.14/1,000 patient-days. Newly acquired ESBL HAIs have remained relatively stable from 2009 to 2019 at 0.09 to 0.05/1,000 patient-days. CRE HAIs are low but stable rates at 0.02/1,000 patient-days (Figure 2). We track antimicrobial utilization for internal and national reporting (starting in July 2017). A SAAR for all Antibacterial agents (ICUs, wards, and oncology units) of 1.33 in 2018. Our top four agents average DOT; piperacillin/tazobactam (66.81), cefepime (34.40), oral levofloxacin (23.56) and intravenous meropenem (21.49). We demonstrate lower average DOT for our restricted antimicrobials (206.21) as compared with our nonrestricted antimicrobials (236.74) (Figure 3). Cost savings continued from year to year. After adjusting for inflation annually, our expected costs ($84.08) compared with actual costs ($40.12 ytd 2019), demonstrates effective cost management of antimicrobial agents. (Figure 4) Conclusion We observed a decrease in HAIs VRE and C. difficile infections after 3 years of operation, and MRSA after 5 years. This downward trend has continued. ESBL HAIs remain relatively stable and CRE are stable at low rates but remain emerging HAIs of concern. We are now focusing efforts on limiting unneeded fluoroquinolone and carbapenem use. We continue to analyze our SAAR data and internal DOT data to identify areas of opportunity to improve antimicrobial use. The ASP outcomes have continued to cost justify ongoing efforts. The effects of the program and the Infection Prevention Department appear to be synergistic. Disclosures All authors: No reported disclosures.
