Prioritizing Equity in Antimicrobial Stewardship Efforts (EASE): a framework for infectious diseases clinicians.

Health equity gaps persist across minoritized groups due to systems of oppression affecting health-related social needs such as access to transportation, education and literacy, or food and housing security. Consequently, disparities in the prevalence of multidrug-resistant infections, infectious disease outcomes, and inappropriate antimicrobial use have been reported across minoritized populations. The Joint Commission and Centers for Medicare and Medicaid Services (CMS) have formally acknowledged the importance of integrating health equity-focused initiatives into existing hospital quality improvement (QI) programs. Here, we review documented disparities in antimicrobial stewardship and offer a framework, derived from components of existing health equity and QI tools, to guide clinicians in prioritizing equity in antimicrobial stewardship efforts (EASE).

Examining Antimicrobial Stewardship Program Implementation in Carceral Settings.

Antimicrobial resistance is a global threat that inequitably affects minoritized populations, including Black, Latinx, and Indigenous people-especially in carceral settings-and is largely driven by inappropriate antimicrobial prescribing practices. People whose identities are minoritized are more likely to be incarcerated, and people who are incarcerated experience higher disease risk than people who are not incarcerated. This article draws on a case of dental infection suffered by a woman who is incarcerated to consider key ethical and clinical complexities of antimicrobial prescribing in carceral settings.

Determining Susceptibility and Potential Mediators of Resistance for the Novel Polymyxin Derivative, SPR206, in Acinetobacter baumannii.

With the increase in carbapenem-resistant A. baumannii (CRAB) infections, there has been a resurgence in the use of polymyxins, specifically colistin (COL). Since the reintroduction of COL-based regimens in treating CRAB infections, several COL-resistant A. baumannii isolates have been identified, with the mechanism of resistance heavily linked with the loss of the lipopolysaccharide (LPS) layer of the bacterial outer membrane through mutations in lpxACD genes or the pmrCAB operon. SPR206, a novel polymyxin derivative, has exhibited robust activity against multidrug-resistant (MDR) A. baumannii. However, there is a dearth of knowledge regarding its efficacy in comparison with other A. baumannii-active therapeutics and whether traditional polymyxin (COL) mediators of A. baumannii resistance also translate to reduced SPR206 activity. Here, we conducted susceptibility testing using broth microdilution on 30 A. baumannii isolates (17 COL-resistant and 27 CRAB), selected 14 COL-resistant isolates for genomic sequencing analysis, and performed time-kill analyses on four COL-resistant isolates. In susceptibility testing, SPR206 demonstrated a lower range of minimum inhibitory concentrations (MICs) compared with COL, with a four-fold difference observed in MIC50 values. Mutations in lpxACD and/or pmrA and pmrB genes were detected in each of the 14 COL-resistant isolates; however, SPR206 maintained MICs ≤ 2 mg/L for 9/14 (64%) of the isolates. Finally, SPR206-based combination regimens exhibited increased synergistic and bactericidal activity compared with COL-based combination regimens irrespective of the multiple resistance genes detected. The results of this study highlight the potential utility of SPR206 in the treatment of COL-resistant A. baumannii infections.

Demographic representation among speakers at the Society for Healthcare Epidemiology of America (SHEA) spring conferences.

BACKGROUND: The Society for Healthcare Epidemiology of America (SHEA) is a leading medical society for infection prevention and antibiotic stewardship. This descriptive study evaluated speaker demographics at the annual SHEA Spring conferences from 2019 to 2022. METHODS: This was a retrospective, descriptive analysis of the demographic composition of speakers at the annual SHEA Spring conferences between 2019 and 2022, excluding the cancelled 2020 conference. Self-reported demographics were available for gender, race, ethnicity, age, primary practice setting, and professional degrees in speaker and membership categories. RESULTS: In total, 447 speaker slots were filled by 305 unique speakers over 3 years. Average annual membership included 55.2% female, 44.8% male, 69.3% White, 21.4% Asian, 6.0% Hispanic/Latino, 2.9% Black, and 0.4% American Indian/Alaska Native or Native Hawaiian/Pacific Islander (AIAN/NHPI); 48.9% did not report a race or ethnicity. Speakers during the same period were 63.5% female, 36.5% male, 68.2% White, 13.3% Asian, 3.8% Black, 3.4% Hispanic/Latino, 0.8% AIAN/NHPI; 13.4% did not report race or ethnicity. In 2021, pharmacists represented 11.6% of speakers (and 2.9% of members) and members with nondoctoral degrees represented 11.6% of speakers (and 21.5% of members) (P < .0001). In each year, we detected underrepresentation of community and private-practice speakers relative to membership (eg, in 2022, 4.3% of speakers vs 15.7% of members; P < .05). CONCLUSIONS: The SHEA Spring conferences demonstrated an increase in pharmacist speakers over time, but speakers from community hospitals and with nondoctoral degrees remain underrepresented relative to membership. Racial and ethnic minoritized individuals remain underrepresented as members and speakers. Intentional interventions are needed to consistently achieve equitable speaker representation across multiple demographic groups.

The implications of data aggregation on propagating racial and ethnic disparities within the health care landscape: Actionable recommendations and considerations for pharmacists.

As the U.S. population becomes more racially and ethnically diverse, it is increasingly important to characterize health inequities for targeted intervention. As it stands, demographic data regarding race and ethnicity for patients and pharmacy trainees alike are aggregated into heterogenous population groups, resulting in findings that may inaccurately reflect the experiences of smaller subgroups. Disaggregation of patient outcomes data can serve to better inform public health interventions for the most vulnerable populations. In pharmacy, disaggregation can allow for better identification of racial and ethnic subgroups who have been traditionally excluded from funding support among other opportunities. In this commentary, we provide historical context and actionable recommendations to better describe our patient and pharmacy trainee populations, with the objectives of improving pharmacist representation and health equity.

Infectious Inequity: How the Gut Microbiome and Social Determinants of Health May Contribute to Clostridioides difficile Infection Among Racial and Ethnic Minorities.

Infectious diseases are a leading contributor to death in the United States, and racial differences in clinical outcomes have been increasingly reported. Clostridioides difficile infection (CDI) is a growing public health concern, as it causes nearly half a million infections per year and considerable excess hospital costs. Concurrent with other infectious diseases, recent literature denotes racial disparities in CDI incidence rates, mortality, and associated morbidity. Of note, investigations into CDI and causative factors suggest that inequities in health-related social needs and other social determinants of health (SDoH) may cause disruption to the gut microbiome, thereby contributing to the observed deleterious outcomes in racially and ethnically minoritized individuals. Despite these discoveries, there is limited literature that provides context for the recognized racial disparities in CDI, particularly the influence of structural and systemic barriers. Here, we synthesize the available literature describing racial inequities in CDI outcomes and discuss the interrelationship of SDoH on microbiome dysregulation. Finally, we provide actionable considerations for infectious diseases professionals to aid in narrowing CDI equity gaps.

Examining racial and social vulnerability disparities in the outpatient treatment of uncomplicated cystitis at a Southern California Academic Hospital.

Racially and ethnically minoritized (REM) patients are disproportionately impacted by infectious diseases. In our study, REM patients were more likely to receive care for urinary tract infections in the emergency department or urgent care, were younger, and were more likely to have higher social vulnerability.

Striving for equity in academia: embracing the power of no in decision-making.

In academia, saying "yes" to opportunities and "no" to distractions is crucial for effective decision-making. Here, we emphasize the importance of carefully considering commitments and courageously declining those that may lead to overextension. We highlight that discernment is vital, particularly for junior faculty/scientists and those with marginalized identities, as overcommitment can hinder career advancement. The "Fame, Fortune, and Fun test" offers a practical heuristic for evaluating opportunities, enabling academics to make informed choices. Saying "no" effectively involves preserving personal and professional integrity by declining tasks that do not align with one's abilities or interests. However, challenges in saying "no" are multifaceted, including fear of missing career advancements, pressures to please superiors or peers, and perceived negative consequences. This decision can be even more complex for individuals with minoritized identities, as additional expectations and responsibilities may arise due to implicit biases. The article provides a scheme for academics when deciding whether to accept or decline opportunities. The "Fame, Fortune, and Fun test" is a simplified scheme based on the Japanese concept of Ikigai, which comes from two words that mean life's purpose. The concept allows an individual to determine their reason for being and aim to align their time spent with as many components that satisfy the following four categories: what one loves, what one is good at, what one can be paid for, and what the world needs. The more overlap, the more alignment with Ikigai, and the more compelling reason to say yes. Once one has determined that they can say no, effectively saying "no" involves clear and direct communication, offering alternatives, expressing gratitude, and considering a "not now" approach if unable to commit immediately. To promote inclusivity, we suggest recommending individuals from diverse backgrounds for opportunities. By amplifying underrepresented voices, we can foster a healthier academic environment. Saying "no" empowers academics to prioritize meaningful contributions and maintain work-life balance. Embracing the power of "no" is essential for maintaining integrity and well-being in academia. Junior faculty/scientists and individuals with marginalized identities may face additional challenges in their decision-making. By carefully evaluating commitments and effectively declining non-aligning opportunities, academics can focus on what truly matters, fostering a supportive and thriving academic environment.

Targeting Dalbavancin Inoculum Effect: Adjunctive Single Dose of Daptomycin.

INTRODUCTION: Daptomycin (DAP) has proven to be a viable alternative amid vancomycin resistance; however, the use of DAP post vancomycin treatment has led to the development of DAP non-susceptible (DNS) strains. Dalbavancin (DAL), a novel single-dosed lipoglycopeptide, has shown enhanced activity against highly resistant Staphylococcus aureus strains. However, on the basis of previous reports and our observations, DAL does not demonstrate similar activity at high versus low inoculum levels. Therefore, we hypothesized that addition of DAP even at minimal concentrations (single dose on day 1) will lower the inoculum to the level that can be cleared by dalbavancin. METHODS: Isolates from methicillin-resistant S. aureus (MRSA)-infected patients with varying susceptibility profiles were evaluated using broth microdilution methods. Two DNS-VISA strains (vancomycin intermediate resistant S. aureus) and one MRSA strain were further evaluated in a one-compartment PK/PD model using a high starting initial inoculum of 109 CFU/mL as well as low initial inoculum of 107 CFU/mL over 168 h to assess the activity of DAL and DAP monotherapy and in combination. RESULTS: Single therapies were not bactericidal when evaluated in the 168 h in vitro one-compartment model with an initial inoculum of 109; however, the combination of DAL plus single dose of DAP resulted in enhanced killing at the end of the 168-h exposure. DAL single therapy caused reduction in colony counts down to detection limit (2 log10 CFU/ml) at a lower inoculum but did not show enhancement (< 2 log10 CFU/ml) at higher initial inoculums (P < 0.01) for all three strains. Similarly, DAP caused initial bacterial reduction up to 4 log10 CFU/ml with regrowth at about 32 h of exposure, which stayed at initial inoculum levels for the duration of the model for all three strains. CONCLUSIONS: Dalbavancin inoculum effect is a major issue in bacterial infections with high bacterial loads and the combination of DAL plus single dose of DAP showed promise in eradicating resistant S. aureus strains at high inoculums.

International consensus recommendations for the use of prolonged-infusion beta-lactam antibiotics: Endorsed by the American College of Clinical Pharmacy, British Society for Antimicrobial Chemotherapy, Cystic Fibrosis Foundation, European Society of Clinical Microbiology and Infectious Diseases, Infectious Diseases Society of America, Society of Critical Care Medicine, and Society of Infectious Diseases Pharmacists: An executive summary.

Intravenous ß-lactam antibiotics remain a cornerstone in the management of bacterial infections due to their broad spectrum of activity and excellent tolerability. ß-lactams are well established to display time-dependent bactericidal activity, where reductions in bacterial burden are directly associated with the time that free drug concentrations remain above the minimum inhibitory concentration (MIC) of the pathogen during the dosing interval. In an effort to take advantage of these bactericidal characteristics, prolonged (extended and continuous) infusions (PI) can be applied during the administration of intravenous ß-lactams to increase time above the MIC. PI dosing regimens have been implemented worldwide, but implementation is inconsistent. We report consensus therapeutic recommendations for the use of ß-lactam PI developed by an expert international panel with representation from clinical pharmacy and medicine. This consensus guideline provides recommendations regarding pharmacokinetic and pharmacodynamic targets, therapeutic drug monitoring considerations, and the use of PI ß-lactam therapy in the following patient populations: severely ill and nonseverely ill adult patients, pediatric patients, and obese patients. These recommendations provide the first consensus guidance for the use of ß-lactam therapy administered as PIs and have been reviewed and endorsed by the American College of Clinical Pharmacy (ACCP), the British Society for Antimicrobial Chemotherapy (BSAC), the Cystic Fibrosis Foundation (CFF), the European Society of Clinical Microbiology and Infectious Diseases (ESCMID), the Infectious Diseases Society of America (IDSA), the Society of Critical Care Medicine (SCCM), and the Society of Infectious Diseases Pharmacists (SIDP).

Identifying the potential impact of a multidisciplinary outpatient antimicrobial therapy program in an area of high social vulnerability.

Background: Outpatient parenteral antimicrobial therapy (OPAT) and complex outpatient antimicrobial therapy (COpAT) are common practice in the management of infectious diseases (IDs). However, providing OPAT/COpAT can pose significant challenges pre- and post-discharge, particularly in vulnerable patient populations. Objectives: The objective of this study is to assess outpatient complications related to OPAT/COpAT in patients discharged with a home health services referral and to identify pre- and post-discharge intervention opportunities and the associated cost-savings that could be achieved with a multidisciplinary ID team-run OPAT/COpAT program. Design/methods: This is a retrospective cohort study of patients who were discharged with OPAT/COpAT through home health services over a 3-month study period. Data on potential pre-discharge interventions and post-discharge complications were recorded. Results: Medication-related issues were the most common pre-discharge complications, accounting for more than 50% of identified intervention opportunities. More than half of the included patients experienced at least one documented outpatient complication post-discharge with peripherally inserted central catheter-line-related complication (20.7%) being the most common issue. Using previously published cost-estimates, the implementation of a designated pre- and post-discharge OPAT/COpAT program could have saved over $100,000 over the 3-month study period. Conclusion: A multidisciplinary OPAT/COpAT program located in a high social vulnerable area can help reduce complications related to a patient's antimicrobial therapy. Medication-related issues represent a major area for potential intervention. Our findings suggest that a multidisciplinary ID team will have ample opportunities to improve the transition of care, at both pre- and post-discharge, for patients requiring antimicrobial therapy.

Utilization of a "Diversity Index" to Assess Racial Diversity of US School of Pharmacy Graduates.

OBJECTIVE: Diversity in the training environment for health professionals is associated with improved abilities for graduates to care for diverse populations. Thus, a goal for health professional training programs, including pharmacy schools, should be to pursue representation among graduates that mirrors that of their communities. METHODS: We evaluate racial and ethnic diversity among graduates of Doctor of Pharmacy (PharmD) programs across the United States (US) over time. Using a "Diversity Index", we quantify the relative racial and ethnic representation of each program's graduates compared with that of college-age graduates nationally and within the geographic region of the respective pharmacy school. RESULTS: Over the past decade, the number of US PharmD graduates increased by 24%. During this time, the number of Black and Hispanic PharmD graduates significantly increased. Still, representation of minoritized populations among graduates continues to be significantly lower compared with US benchmark populations. Only 16% of PharmD programs had a Diversity Index that matched or exceeded their benchmark comparator Black or Hispanic populations. CONCLUSION: These findings highlight the significant opportunity that exists to increase the diversity of graduates of US PharmD programs to better reflect the diversity of the US population.

Academic Activism: An Avenue to Action.

Until now, the term "advocacy" in pharmacy education and practice has focused on advocating for the advancement of the pharmacy profession or patient advocacy. With the 2022 Curricular Outcomes and Entrustable Professional Activities publication, the focus of advocacy has broadened to include advocacy for other causes that impact the health of patients. This commentary will highlight 3 pharmacy-focused organizations advocating for social issues impacting the health of patients as well as encourage members of the Academy to continue to expand personal social advocacy efforts.

Examining the impact of racial disparities on Clostridioides difficile infection outcomes at a Southern California academic teaching hospital.

Racial differences in Clostridioides difficile infection (CDI) outcomes have been reported. In this study, minoritized patients with CDIs had prolonged hospitalizations and increased intensive care unit admissions. Chronic kidney disease was shown to partially mediate the relationship between race or ethnicity and severe CDI. Our findings suggest potential areas for equitable interventions.
