Successfully educating urgent care patients on appropriate use and risks of antibiotics can be challenging. We assessed the conscious and subconscious impact various educational materials (informational handout, priming poster, and commitment poster) had on urgent care patients’ knowledge and expectations regarding antibiotics.

Stratified Block Randomized Control Trial.

Urgent care centers (UCCs) in Colorado, Florida, Georgia, and New Jersey.

Urgent care patients.

We randomized 29 UCCs across six study arms to display specific educational materials (informational handout, priming poster, and commitment poster). The primary intention-to-treat (ITT) analysis evaluated whether the materials impacted patient knowledge or expectations of antibiotic prescribing by assigned study arm. The secondary as-treated analysis evaluated the same outcome comparing patients who recalled seeing the assigned educational material and patients who either did not recall seeing an assigned material or were in the control arm.

Twenty-seven centers returned 2,919 questionnaires across six study arms. Only 27.2% of participants in the intervention arms recalled seeing any educational materials. In our primary ITT analysis, no difference in knowledge or expectations of antibiotic prescribing was noted between groups. However, in the as-treated analysis, the handout and commitment poster were associated with higher antibiotic knowledge scores.

Educational materials in UCCs are associated with increased antibiotic-related knowledge among patients when they are seen and recalled; however, most patients do not recall passively displayed materials. More emphasis should be placed on creating and drawing attention to memorable patient educational materials.

This qualitative study aimed to understand facilitators and barriers to implementation of interventions to improve guideline-concordant antibiotic duration prescribing for pediatric acute otitis media (AOM).

Clinicians and clinic administrators participated in semi-structured qualitative interviews, and parents of children 2 years of age or older with a recent diagnosis of AOM participated in focus groups. The Practical Robust Implementation and Sustainability Model (PRISM) guided the study. Interviews were analyzed using the Rapid Assessment Process.

Denver Health and Hospital Authority (Denver, CO) led the study. Recruitment occurred at Vanderbilt University Medical Center (Nashville, TN) and Washington University in St. Louis Medical Center (St. Louis, MO).

Purposeful sampling was used to recruit clinicians and administrators for qualitative interviews. Convenience sampling was used to recruit parents for focus groups.

Thirty-one participants (15 clinicians, 4 administrators, and 12 parents) engaged in interviews and focus groups. Factors influencing antibiotic prescribing included patient history, years of practice, familiarity with the patient, concerns with patient medication adherence, and practice type. Clinicians endorsed electronic health record modifications and clinician prescribing feedback as methods to improve patient care and reduce the durations of prescribed antibiotics. Suggestions for intervention optimization and education needs were also obtained.

Findings suggest that clinicians and administrators support reducing prescribed antibiotic durations for AOM and are receptive to the proposed interventions. More education is needed to increase parent awareness about antibiotic stewardship and AOM treatment options.

Social media has become an important tool in monitoring infectious disease outbreaks such as coronavirus disease 2019 and highly pathogenic avian influenza (HPAI). Influenced by the recent announcement of a possible human death from H5N2 avian influenza, we analyzed tweets collected from X (formerly Twitter) to describe the messaging regarding the HPAI outbreak, including mis- and dis-information, concerns, and health education.

We collected tweets involving keywords relating to HPAI for 5 days (June 04 to June 08, 2024). Using topic modeling, emotion, sentiment, and user demographic analyses, we were able to describe the population and the HPAI-related topics that users discussed.

With an original pool of 14,796 tweets, we analyzed a final data set of 13,319 tweets from 10,421 unique X users, with 50.4% of the tweets exhibiting negative sentiments (< 0 on a scale of −4 to +4). Predominant emotions were anger and fear shown in 36.4% and 29.5% of tweets, respectively. We identified 5 distinct, descriptive topics within the tweets. The use of emotionally charged language and spread of misinformation were substantial.

Mis- and dis-information about the causes of and ways to prevent HPAI infections were common. A large portion of the tweets contained references to a planned epidemic or “plandemic” to influence the upcoming 2024 US presidential election. These tweets were countered by a limited number of tweets discussing infection locations, case reports, and preventive measures. Our study can be used by public health officials and clinicians to influence the discourse on current and future outbreaks.

The present study aimed to describe ICU antibiotic use based on data reported from 2009 to 2018 to the Nosocomial Surveillance System (NSS) of the State Health Department in the State of Sao Paulo, Brazil.

Ecological study.

Data obtained from hospitals located in the state of São Paulo, Brazil from 2009 to 2018.

Intensive care units located at participant hospitals.

Data on healthcare-associated infections, antibiotic usage, and bacterial identification were collected and reported monthly by hospitals. Antibiotic consumption was quantified as defined daily doses (DDD) per 1000 patient-days. The relationship between antibiotic use and bacterial resistance, categorized by hospital type and ICU complexity, was analyzed using statistical methods to assess correlations and significance.

Our findings reveal an escalating trend in antibiotic consumption over the study period, with a notable increase from 588.16 DDD per 1000 patient-days in the initial year to 943.12 DDD/1000 patient-days in the final year (p < 0.01). Cephalosporins emerged as the most frequently utilized class, accounting for 33.9% of total antibiotic consumption. Public hospitals exhibited significantly higher antibiotic use compared to private and philanthropic institutions, with a mean of 889.11 DDD/1000 patient-days in public hospitals compared to 849.07 DDD/1000 patient-days in private hospitals and 785.12 DDD/1000 patient-days in philanthropic hospitals (p < 0.05).

The study provides critical insights into antibiotic use and resistance in different hospital settings, emphasizing the importance of tailored antimicrobial stewardship strategies.

In June of 2024, Becton Dickinson experienced a blood culture bottle shortage for their BACTEC system, forcing health systems to reduce usage or risk exhausting their supply. Virginia Commonwealth University Health System (VCUHS) in Richmond, VA decided that it was necessary to implement austerity measures to preserve the blood culture bottle supply.

VCUHS includes a main campus in Richmond, VA as well as two affiliate hospitals in South Hill, VA (Community Memorial Hospital (CMH)) and Tappahannock Hospital in Tappahannock, VA. It also includes a free-standing Emergency Department in New Kent, VA.

Blood cultures from both pediatric and adult patients were included in this study.

VCUHS intervened to decrease blood culture utilization across the entire health system. Interventions included communication of blood culture guidance as well as an electronic health record order designed to guide providers and discourage wasteful ordering.

Post-implementation analyses showed that interventions reduced overall usage by 35.6% (P < .0001) and by greater than 40% in the Emergency Departments. The impact of these changes in utilization on positivity were analyzed, and it was found that the overall positivity rate increased post-intervention from 8.8% to 12.1% (P = .0115) and in the ED specifically from 10.2% to 19.5% (P < .0001).

These findings strongly suggest that some basic stewardship interventions can significantly change blood culture practice in a manner that minimizes the impact on patient care.

This study aimed to evaluate appropriate antimicrobial prescribing after implementing a pneumonia order set within a community teaching hospital.

Retrospective chart review study.

450-bed community teaching hospital.

Patients who are 18 years of age or older admitted for treatment of community-acquired pneumonia (CAP) between October 1, 2021, and August 1, 2023.

This retrospective cohort study aimed to evaluate a composite endpoint of appropriate empiric antimicrobial selection, dosing, and duration in accordance with the national guidelines after the implementation of a CAP order set. Secondary outcomes included comparing hospital length of stay (LOS), readmission rates, mortality rates, and Clostridium difficile infection rates.

A total of 236 patients were included (118 patients per group). Significantly more patients in the post-implementation group received guideline-concordant therapy for CAP (5.9% vs 35.6%, P < .001). Results were heavily influenced by improvements in appropriate durations of therapy (pre: 6.8% vs post: 39.9%, P < .001). There were no significant differences observed for LOS, 30-day readmission rates, C. difficile infections within 30 days, or mortality rates between groups. The order set was utilized in 66.1% of patients included in the post-implementation group.

Implementing an order set significantly improved inpatient antibiotic prescribing for CAP with no difference in clinical or safety outcomes. Antibiotic order sets will be a useful tool for antimicrobial stewardship program expansion into other common community-acquired infections.

To analyze antimicrobial prescribing practices in Australian emergency departments (ED), identifying prescribing areas requiring improvement. This aims to inform antimicrobial stewardship (AMS) strategies to enhance antimicrobial prescribing quality.

Retrospective analysis of the Hospital National Antimicrobial Prescribing Survey (NAPS) data set.

EDs in public and private Australian hospitals (n = 652).

Hospitals (n = 652) that participated in the Hospital NAPS from 2013 to 2022.

Data were collected by trained auditors from participating hospitals with the use of a standardized auditing tool, the Hospital NAPS. Data from 2013 to 2022 were analyzed descriptively. Variables assessed included guideline compliance and appropriateness by antimicrobial and indication, and reasons for inappropriateness.

There were 3,098 antimicrobial prescriptions from EDs included for analysis. Guideline compliance (63.5%) and appropriateness (70.4%) in EDs were lower compared to overall prescribing practices from all departments. The most commonly prescribed antimicrobial was ceftriaxone (16.9%, n = 523), and the most common indication was empiric prescribing for community-acquired pneumonia (16.0%, n = 497). Amoxicillin-clavulanic acid (53.2%, n = 99), and acute exacerbation of chronic obstructive pulmonary disease (54.3%, n = 57), were the antimicrobial and indication with the lowest rates of appropriateness respectively. Ceftriaxone prescribing also had a low rate of appropriateness (62.3%, n = 326). Selection of antimicrobials with too broad of a spectrum was the most common reason for inappropriateness (40.2%).

Antimicrobial prescribing quality in EDs warrants improvement. Recommended targets for AMS interventions are the excessive and inappropriate use of broad-spectrum antimicrobials such as ceftriaxone and amoxicillin-clavulanic acid in common respiratory and urinary tract infections.

To compare the recovery of yeast from hospital surfaces from two different collection methods: Eswab moistened with molecular water, and premoistened stick-mounted sponge.

Comparison of collection methods for the recovery of yeast in the hospital environment.

This study took place at intensive care units of a large academic medical center.

The increase in severe acute respiratory coronavirus virus 2 (SARS-CoV-2) cases due to the omicron strain led to reduced acute care hospital beds at the Veterans Administration (VA) Hospital, North Texas; veterans with non-severe coronavirus disease 2019 (COVID-19) disease were managed at a community living center (CLC), a VA nursing home. The management of non-severe COVID-19 in VA nursing homes has not been extensively described.

We describe resident characteristics and outcomes, and infection control practices implemented during 2 COVID-19 outbreak periods (January 12–February 15, 2022, June 28–July 14, 2023). Serial testing of all CLC residents was conducted, and residents with polymerase chain reaction-confirmed SARS-CoV-2 (COVID-19) infection were included in the analysis. Resident data were ascertained from the COVID-19 facility dashboard and medical record system.

From January 12 to February 15, 2022, and June 28–July 14, 2023, 62 adults residing at the CLC were diagnosed with COVID-19. Overall, the median age was 75 years [interquartile range, 71–80], and 57 (91.9%) were men. Residents were cohorted by COVID-19 test results. A multidisciplinary team was convened, and staff were fit tested for appropriate personal protective equipment (PPE) and received refresher training on hand hygiene, donning, and doffing of PPE. Thirty-seven (59.7%) residents were symptomatic. Overall, 55 (88.7%) residents were documented to have received the SARS-CoV-2 primary vaccination series. Most residents were managed at the CLC, while 12 (19.3%) were hospitalized in acute care.

It is feasible to manage high-risk residents with non-severe COVID-19 disease in a CLC utilizing a multidisciplinary approach and implementing Infection Prevention and Control strategies.

Identify essential components of a curriculum on antimicrobial stewardship (AS) for pediatric residents.

Survey.

Academic tertiary care children’s hospital.

Pediatric residents and infectious diseases (ID)/AS content experts (CE), including pediatric ID faculty, fellows, nurse practitioners, and pharmacists.

Residents were surveyed to assess prior AS experiences and usefulness of education in different AS domains (e.g., antimicrobial resistance [AMR]). CE was surveyed to identify content to include in an AS curriculum. A specific topic (e.g., resistance in Staphylococcus aureus) achieved consensus if ≥80% of CE identified the topic as “very” or “extremely” important.

Thirty-three of 110 pediatric residents responded to the resident survey (response rate 30%). Spectrum of activity (97%), empiric therapy (94%), and duration of therapy (94%) were the domains identified by the most residents as “very” or “extremely” useful. All CE responded to the CE survey (n=26). Thirty-nine of 105 topics (37%) met the consensus threshold. The domains with most topics achieving consensus were empiric therapy (11/13 topics, 85%) and duration of therapy (5/8 topics, 63%). Only one topic was identified within the domains of antibiotic allergies, diagnostics, and AMR, reflecting 18%, 14%, and 6% of the potential topics within each domain, respectively.

A pediatric AS curriculum focused on empiric therapy and duration of therapy is likely to meet the needs of both learners and CEs.

Discrepancies or inaccuracies between testing methods can create confusion or lead to clinical harm if antibiotics are inappropriately chosen. We report our clinical experience using the Accelerate Pheno™ followed by routine automated susceptibilities by the Vitek®2 for positive blood cultures with gram-negative rods.

This was a retrospective review of positive gram-negative blood cultures, including comparison of susceptibility testing results and impact on clinical care.

Academic teaching hospital.

All patients admitted to the hospital with gram-negative bacteremia from January 2020 to December 2022.

Microbiology was reviewed for discrepancies as defined by very major errors (VMEs), major errors (MEs), and minor errors (mEs). Clinical charts were reviewed for antibiotic therapy.

Positive blood cultures with gram-negative rods were included (n = 262). Between these two methods, overall essential agreement was 93.7% (2162/2304) and categorical agreement 93.5% (2159/2306). There were 147 discrepancies noted, including 6 VMEs, 25 MEs, and 116 mEs accounting for 96 patients. Antibiotic choice was changed in 8 patients due to perceived suboptimal empiric therapy based on the rapid susceptibility results.

The Accelerate Pheno tended to over-call resistance compared to the Vitek®2. Few patients (8) received the incorrect antibiotic based on the Pheno result. Stewardship programs may choose to optimize their rapid antibiotic susceptibility testing reporting to help minimize confusion and guide appropriate antibiotic selection.

This systematic review aims to synthesize evidence from current literature to describe how Electronic Medical Record (EMR) primary care data have been used for antimicrobial stewardship activities internationally.

Systematic literature review.

We searched Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Embase, Scopus, and Web of Science from January 1, 2013 to September 23, 2023 to retrieve studies that included concepts of “antimicrobial stewardship,” “primary care,” and “electronic medical records.” We used narrative synthesis to classify and interpret results. Data were grouped and tabulated by similar themes and concepts, including strengths, facilitators, barriers, and limitations for antimicrobial stewardship.

A total of 265 articles were identified from the initial search, of which 34 full-text articles from 10 countries met all criteria and were included in the review. Six categories of EMR data use were identified from the studies, these were for: assessing antimicrobial prescribing quality, measuring the effectiveness of an intervention, analyzing antimicrobial prescribing trends, assessing patient and provider characteristics in prescribing, evaluating novel tools or measures, and measuring specific conditions and outcomes. Facilitators of use of EMR data were generally well-described across the studies reviewed; however, barriers were not. Barriers described were centered around EMR system design and technical challenges in data extraction. Completeness of EMR data was the most consistently described limitation.

Our study highlights the range of uses of EMR data in supporting AMS in primary care internationally, and its strengths, facilitators, and barriers to use.

This study analyzed the practice of switching intravenous antibiotics to oral dosage form in a tertiary care hospital of Nepal.

A prospective observational study was performed among patients admitted to medical/surgical wards in a private tertiary care hospital of Nepal.

Hospitalized adult patients who received IV antibiotics for at least 48 hours and met the eligibility criteria were enrolled in the study. The detailed information on use of antibiotics such as indication, duration, type time of switch etc. were collected and analyzed.

Among 335 patients, 282(83.9%) met the eligibility criteria for intravenous (IV) to oral conversion however, only 18.7% of patients were switched to oral regimen. Step-down conversion was the common type of IV to oral switch. Almost all patients were empirically treated with β-lactams antibiotics (n = 327). There was significant association between the antibiotic class and duration of IV therapy (P < 0.001). The length of hospital stays and duration of IV antibiotics therapy was lower in the timely converted group than in the non-converted groups (P < 0.001). The duration of IV antibiotics therapy was strongly correlated with duration of hospital stay (r = 0.743, P < 0.001).

The findings revealed a low prevalence of conversion from IV antibiotics to oral, despite a higher percentage of patients meeting the eligibility criteria for conversion. There is a need for the implementation of structured program to review patients on IV antibiotics and promote timely conversion to oral once they meet the conversion criteria.
