Background: The University of Washington (UW) Center for Stewardship in Medicine (CSiM) supports a tele-antimicrobial stewardship (AMS) program (TASP) using the ECHO approach (Extension for Community Healthcare Outcomes) in small, rural, and Critical Access Hospitals (primarily in the western U.S.) with education, mentoring, organizational capacity building, and a community of peers. To evaluate the continuing education (CE) component of UW-TASP ECHO, CSiM surveyed individuals receiving CE credits as part of the program. This survey was designed to track individuals’ satisfaction with the program and to assess the impact of UW-TASP ECHO on AMS in participating facilities. Methods: The CE participants’ survey was completed annually by individuals participating in UW TASP ECHO using online survey software. The survey included closed-ended and open-ended questions. Responses to open-ended questions were entered into Atlas.ti qualitative analysis software and coded iteratively according to themes that emerged. When a new code emerged partway through the coding process, earlier surveys were re-coded for the new code. Final codes were grouped into themes and sub-themes and quotes from each theme identified were summarized and attached to the theme and reported. Results: Data from three administrations of this survey were available: 2018-2019 (n=66); 2020-2021 (n=27); and 2021-2022 (n=30). These surveys were completed by a total of 95 individuals from 53 hospitals. Seven of these individuals completed a survey in each year, 14 completed a survey in two years, and 74 completed only one survey. Themes identified were COVID-19 support (including procedures and policies, being kept up-to-date, research summaries, and peer support), the antibiotic pocket guide developed by UW, strength in community, staff education, role of CSiM in developing/strengthening the AMS program at the facility, change in use of antibiotics, UW imprimatur, learning/growing as a healthcare provider, and importance for small, rural hospitals (see examples in Table 1). Conclusions: This qualitative analysis provides evidence from surveys of individuals participating in CE that UW TASP ECHO has had a meaningful impact in such domains as building a strong community among small, rural and critical access hospitals, educating staff, changing antibiotic use and providing peer support, among others.

Background: Inappropriate diagnosis and treatment of urinary tract infections (UTI) contributes to antibiotic overuse. The Inappropriate Diagnosis of UTI (ID-UTI) measure—which quantifies the percentage of treated bacteriuria that is asymptomatic (ASB) using a standard definition of UTI—has been validated in acute care hospitals, but not in critical access hospitals (CAHs) where resources differ. Methods: From October 2022-July 2023, ten CAHs participated in a program to reduce ASB treatment, including education, coaching, and hospital feedback using the ID-UTI measure. Our primary aim was to assess performance characteristics of the ID-UTI standard definition and measure in CAHs (Figure 1). Non-physician abstractors from each CAH submitted clinical data (e.g., signs/symptoms) via REDCap for consecutive adult patients who were admitted or discharged from the emergency department and received antibiotics for bacteriuria. The case abstraction goal for each CAH was 5-6 cases/month. To assess feasibility, we evaluated the ability of each CAH to achieve goal case abstractions. To assess validity and reliability of the ID-UTI standard definition, two physicians reviewed 10% of submitted cases using deidentified patient notes and assessed agreement with the standard ID-UTI definition and consensus clinical opinion. Based on submitted data, we provided bi-monthly feedback reports to CAHs including the hospital-level ID-UTI measure to benchmark progress and for peer comparison. We measured monthly change in the ID-UTI measure using a mixed-effects logistic regression model (Figure 1, Figure 2). Results: Among 10 CAHs, 4 (40%) submitted >59 cases over 10 months (goal) while 3 (30%) submitted >35 cases (secondary goal). Physician reviewers assessed 9.5% (58/608) of cases. Utilizing the ID-UTI standard definition, there was high agreement (93%) in ASB vs UTI designation between each physician reviewer and the CAH’s REDCap assessment (Figure 3). Compared to clinical opinion, the ID-UTI standard definition identified 48% (16/33) of ASB cases and 100% (25/25) of UTI cases (Figure 4). Over the program, the percentage of cases treated for UTI that were ASB decreased from 28.4% (range 0-63%) to 18.6% (range, 0-33%; p=0.055) (Figure 5). Conclusions: Case abstraction with use of the ID-UTI measure was feasible and reliable to implement with modifications for CAHs. Data collection by untrained staff was as reliable as physician adjudication. Though the ID-UTI standard definition undercounted ASB cases (low sensitivity), cases reported as ASB were always ASB when adjudicated (high specificity). The program, including performance feedback using the ID-UTI measure, was associated with a trend toward lower treatment of ASB.

Among 143 cases of National Healthcare Safety Network (NHSN) catheter-associated urinary tract infections (CAUTI), 40% were considered catheter-associated asymptomatic bacteriuria (CA-ASB), and 18% clinical CAUTI. An alternative source of fever was present in 70% of CA-ASB. NHSN CAUTI may not be an effective metric for tracking hospital-level infection prevention efforts.

We describe our experience implementing an intensive quality improvement cohort pilot focused on managing asymptomatic bacteriuria in 19 critical access hospitals. Participation in the pilot was high, and almost all sites identified an improvement goal and collected clinical data. Barriers to implementation included staffing shortages, turnover, and lack of bandwidth.

Background: Antibiotics are prescribed to nearly onehalf of patients with viral respiratory tract infections (RTI) in outpatient settings. This use is ineffective and may cause undue harm and excess cost from unnecessary antibiotic exposure. We implemented a multifaceted intervention to address inappropriate antibiotic prescribing for viral RTI. Here, we discuss the impact over 4 years, before and during the SARS-CoV-2 pandemic. Methods: This observational study describes the implementation and initial impact of a multimodal stewardship intervention on inappropriate antibiotic prescribing for viral RTIs in outpatient care settings at a single centre. We tracked the rate of visits for viral RTI as well as antibiotic prescribing for viral RTIs in urgent care, primary care and the emergency department between January 2018 and March 2022. Data were collected 1 year prior to implementation and 3 years after implementation. The primary outcome – the rate of inappropriate antibiotics prescribed for viral RTIs – was described by calendar year (CY) to review changes after the stewardship intervention. Results: In CY2018, the year prior to implementation of targeted RTI antimicrobial stewardship, the rate of inappropriate RTI antibiotics prescribed was 10% in urgent care, 11% in primary care and 18% in the emergency department (ED). During the first CY of the intervention, rates were 8% in urgent care, 10% in primary care and 16% in the ED. In CY2020, the second year of the intervention, inappropriate RTI antibiotics were prescribed in 5% of urgent care and 3% primary care RTI visits and 15% of ED RTI visits. These rates were similar in CY2021 and the first 3 months of CY2022. Over 30,000 visits for RTIs were seen annually in CY2018 and CY2019. Annual RTI visits dropped to 20,222 in CY2020 and 14,172 in CY2021. Conclusion: Although total visits for non-COVID RTIs decreased by approximately 50% during the first 2 years of the SARS-CoV-2 pandemic, an antimicrobial stewardship intervention was associated with decreases in inappropriate antibiotic prescribing for RTIs. This was maintained throughout 2 years of the pandemic.

Background: Western State Hospital (WSH) is an 800-bed, state-owned psychiatric hospital in Washington State which services individuals in 20 counties. WSH provides services and inpatient treatment to patients referred via behavioral health providers and/or the civil court system. Because many patients are admitted with serious, long-term illness, WSH also provides primary care and addresses infectious syndromes encountered in admitted patients. In January 2016, WSH officially began their antimicrobial stewardship program (ASP). In 2017 WSH joined the UW Center for Stewardship in Medicine (UW-CSiM) to grow and optimize their ASP. Methods: The lead pharmacist at WSH participated in weekly hour-long education and tele-mentoring sessions through the UW-CSiM program. Educational materials were adapted from UW-CSiM didactics and delivered to providers during regular meetings and grand rounds. Daily pharmacist led prospective audit with feedback was conducted. Antibiotic use data were collected and measured by days of therapy (DOT) per 1000-patient days from pharmacy dispensing records from 2015 to 2022. Results: From 1/1/15 to 12/31/22, there was a consistent trend of decreasing antibiotic consumption annually. In particular, antibiotic use decreased by over 65% ranging from 35-43 DOT per 1000 patient-days in 2015 to 9-11 DOT per 1000 patient-days in 2022 (Figure 1). This translates to approximately 1000 antibiotic days of therapy in 2015 and 200 days of antibiotic therapy in 2022. As of 2022, the two most common antibiotics used were cephalexin and sulfamethoxazole/trimethoprim Conclusion: Although treating infections is not a principal focus of a psychiatric hospital, patients receiving care in inpatient psychiatric facilities do experience common infections and receive antibiotics during their stay. At WSH, initiation of an antimicrobial stewardship program was associated with sustained decrease in total antibiotic DOT over 7 years. These data highlight the impact of tele-education and tele-mentoring in infectious diseases and antimicrobial stewardship as a path to build a successful antimicrobial stewardship even without formal infectious diseases training. Our single center experience at a large psychiatric hospital demonstrates the use of antimicrobials in these facilities and the opportunity for a large impact of an antimicrobial stewardship program in inpatient psychiatric facilities.

The ability to provide feedback to a colleague is a key skill required for professional growth and patient safety. However, these conversations are limited by time constraints, differences in values, and a culture of “noninterference.” This advocacy-inquiry-identify-teach framework creates an organized approach to initiating successful “challenging” conversations with peers.

Bacterial superinfection and antibiotic prescribing in the setting of the current mpox outbreak are not well described in the literature. This retrospective observational study revealed low prevalence (11%) of outpatient antibiotic prescribing for bacterial superinfection of mpox lesions; at least 3 prescriptions (23%) were unnecessary.

We compared experiences with The Multifaceted Intervention to Improve Prescribing for Acute Respiratory Infection for Adult and Children in Emergency Department and Urgent Care Settings versus Choosing Wisely to evaluate inappropriate antimicrobial prescribing in ambulatory care. Both identified the same clinics, diagnoses, and antibiotics for high-yield antibiotic stewardship interventions.
