RESUMEN
CONTEXT: The 2022 United States mpox outbreak disproportionately affected racial and ethnic minority gay, bisexual, and other men who have sex with men. PROGRAM: We utilized surveillance data and vaccination registries to determine whether populations most impacted by mpox in Alameda County received JYNNEOS vaccines and tecovirimat (TPOXX) during June 1-October 31, 2022. IMPLEMENTATION: Alameda County Public Health Department responded to the mpox epidemic through partnerships with local health care providers who serve communities disproportionately affected by mpox. EVALUATION: During June 1-October 31, 2022, a total of 242 mpox cases were identified in Alameda County. Mpox incidence rates per 100 000 were highest among Black/African American (35.7; 95% confidence interval [CI], 26.8-46.5) and Hispanic/Latinx (25.1; CI, 20.1-30.9) residents, compared to Asian (3.8; CI, 2.3-5.9) and White (10.5; CI, 7.7-13.9) residents. Most confirmed cases were identified as gay, lesbian, or same-gender-loving (134, 67.3%) and bisexual (31, 15.6%); 226 (93.8%) cases were male. Sixty-nine (28.5%) mpox patients received TPOXX. There were no statistically significant differences in demographic and clinical characteristics of mpox cases when compared by TPOXX receipt status. JYNNEOS vaccine was received by 8277 Alameda County residents. The largest proportion of vaccinees were White residents (40.2%). Administration rates per 100 000 men who have sex with men were lowest among Asian and Hispanic/Latinx individuals, at 8779 (CI, 8283-9296) and 14 953 (CI, 14 156-15 784), respectively. Black/African American and Hispanic/Latinx males had the lowest vaccination-to-case ratios at 16.7 and 14.8, respectively. DISCUSSION: Mpox disproportionately affected Black/African American and Hispanic/Latinx men who have sex with men in Alameda County. Strong partnerships with local health care providers ensured that persons with mpox received TPOXX treatment when indicated. However, higher JYNNEOS vaccine uptake in Black and Latinx communities needs improvement through ongoing and meaningful engagement with Black/African American and Hispanic/Latinx gay, bisexual, and transgender communities.

The incidence of spotted fever group (SFG) rickettsioses in the United States has tripled since 2010. Rocky Mountain spotted fever, the most severe SFG rickettsiosis, is caused by Rickettsia rickettsii. The lack of species-specific confirmatory testing obfuscates the relative contribution of R. rickettsii and other SFG Rickettsia to this increase. We report a newly recognized rickettsial pathogen, Rickettsia sp. CA6269, as the cause of severe Rocky Mountain spotted fever-like illness in 2 case-patients residing in northern California. Multilocus sequence typing supported the recognition of this pathogen as a novel Rickettsia genotype most closely related to R. rickettsii. Cross-reactivity observed for an established molecular diagnostic test indicated that Rickettsia sp. CA6269 might be misidentified as R. rickettsii. We developed a Rickettsia sp. CA6269-specific real-time PCR to help resolve this diagnostic challenge and better characterize the spectrum of clinical disease and ecologic epidemiology of this pathogen.

Objective: Carbapenem-resistant organisms (CROs) are an urgent health threat. Since 2017, Alameda County Health Public Health Department (ACPHD) mandates reporting of carbapenem-resistant Enterobacterales (CRE) and encourages voluntary reporting of non-CRE CROs including carbapenem-resistant Acinetobacter baumannii (CRAB) and carbapenem-resistant Pseudomonas aeruginosa (CRPA). Surveillance data from ACPHD were analyzed to describe the epidemiology of CROs and target public health interventions. Methods: Healthcare facilities in Alameda County reported CRO cases and submitted isolates to ACPHD to characterize carbapenemase genes; deaths were identified via the California Electronic Death Registration System. CRO cases with isolates resistant to one or more carbapenems were analyzed from surveillance data from July 2019 to June 2021. Results: Four hundred and forty-two cases of CROs were reported to Alameda County from 408 patients. The county case rate for CROs was 29 cases per 100,000 population, and cases significantly increased over the 2-year period. CRPA was most commonly reported (157 cases, 36%), and cases of CRAB increased 1.83-fold. One-hundred eighty-six (42%) cases were identified among residents of long-term care facilities; 152 (37%) patients had died by January 2022. One hundred and seven (24%) cases produced carbapenemases. Conclusions: The high burden of CROs in Alameda County highlights the need for continued partnership on reporting, testing, and infection prevention to limit the spread of resistant organisms. A large proportion of cases were identified in vulnerable long-term care residents, and CRAB was an emerging CRO among this population. Screening for CROs and surveillance at the local level are important to understand epidemiology and implement public health interventions.
RESUMEN
Since the initial publication of A Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals in 2008, the prevention of healthcare-associated infections (HAIs) has continued to be a national priority. Progress in healthcare epidemiology, infection prevention, antimicrobial stewardship, and implementation science research has led to improvements in our understanding of effective strategies for HAI prevention. Despite these advances, HAIs continue to affect â¼1 of every 31 hospitalized patients, leading to substantial morbidity, mortality, and excess healthcare expenditures, and persistent gaps remain between what is recommended and what is practiced.The widespread impact of the coronavirus disease 2019 (COVID-19) pandemic on HAI outcomes in acute-care hospitals has further highlighted the essential role of infection prevention programs and the critical importance of prioritizing efforts that can be sustained even in the face of resource requirements from COVID-19 and future infectious diseases crises.The Compendium: 2022 Updates document provides acute-care hospitals with up-to-date, practical expert guidance to assist in prioritizing and implementing HAI prevention efforts. It is the product of a highly collaborative effort led by the Society for Healthcare Epidemiology of America (SHEA), the Infectious Disease Society of America (IDSA), the Association for Professionals in Infection Control and Epidemiology (APIC), the American Hospital Association (AHA), and The Joint Commission, with major contributions from representatives of organizations and societies with content expertise, including the Centers for Disease Control and Prevention (CDC), the Pediatric Infectious Disease Society (PIDS), the Society for Critical Care Medicine (SCCM), the Society for Hospital Medicine (SHM), the Surgical Infection Society (SIS), and others.

This document introduces and explains common implementation concepts and frameworks relevant to healthcare epidemiology and infection prevention and control and can serve as a stand-alone guide or be paired with the "SHEA/IDSA/APIC Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals: 2022 Updates," which contain technical implementation guidance for specific healthcare-associated infections. This Compendium article focuses on broad behavioral and socio-adaptive concepts and suggests ways that infection prevention and control teams, healthcare epidemiologists, infection preventionists, and specialty groups may utilize them to deliver high-quality care. Implementation concepts, frameworks, and models can help bridge the "knowing-doing" gap, a term used to describe why practices in healthcare may diverge from those recommended according to evidence. It aims to guide the reader to think about implementation and to find resources suited for a specific setting and circumstances by describing strategies for implementation, including determinants and measurement, as well as the conceptual models and frameworks: 4Es, Behavior Change Wheel, CUSP, European and Mixed Methods, Getting to Outcomes, Model for Improvement, RE-AIM, REP, and Theoretical Domains.

OBJECTIVES: To use a standardized tool for a multicenter assessment of antibiotic appropriateness in ICUs and identify local antibiotic stewardship improvement opportunities. DESIGN: Pilot point prevalence conducted on October 5, 2016; point prevalence survey conducted on March 1, 2017. SETTING: ICUs in 12 U.S. acute care hospitals with median bed size 563. PATIENTS: Receiving antibiotics on participating units on March 1, 2017. INTERVENTIONS: The Centers for Disease Control and Prevention tool for the Assessment of Appropriateness of Inpatient Antibiotics was made actionable by an expert antibiotic stewardship panel and implemented across hospitals. Data were collected by antibiotic stewardship program personnel at each hospital, deidentified and submitted in aggregate for benchmarking. hospital personnel identified most salient reasons for inappropriate use by category and agent. MEASUREMENTS AND MAIN RESULTS: Forty-seven ICUs participated. Most hospitals (83%) identified as teaching with median licensed ICU beds of 70. On March 1, 2017, 362 (54%) of 667 ICU patients were on antibiotics (range, 8-81 patients); of these, 112 (31%) were identified as inappropriate and administered greater than 72 hours among all 12 hospitals (range, 9-82%). Prophylactic antibiotic regimens and PICU patients demonstrated a statistically significant risk ratio of 1.76 and 1.90 for inappropriate treatment, respectively. Reasons for inappropriate use included unnecessarily broad spectrum (29%), no infection or nonbacterial syndrome (22%), and duration longer than necessary (21%). Of patients on inappropriate antibiotic therapy in surgical ICUs, a statistically significant risk ratio of 2.59 was calculated for noninfectious or nonbacterial reasons for inappropriate therapy. CONCLUSIONS: In this multicenter point prevalence study, 31% of ICU antibiotic regimens were inappropriate; prophylactic regimens were often inappropriate across different ICU types, particularly in surgical ICUs. Engaging intensivists in antibiotic stewardship program efforts is crucial to sustain the efficacy of antibiotics and quality of infectious diseases care in critical care settings. This study underscores the value of standardized assessment tools and benchmarking to be shared with local leaders for targeted antibiotic stewardship program interventions.

The diagnosis and management of urinary tract infections (UTIs) among residents of post-acute and long-term care (PALTC) settings remains challenging. Nonspecific symptoms, complex medical conditions, insufficient awareness of diagnostic criteria, and unnecessary urine studies all contribute to the inappropriate diagnosis and treatment of UTIs in PALTC residents. In 2017, the Infection Advisory Subcommittee at AMDA-The Society for Post-Acute and Long-Term Care Medicine convened a workgroup comprised of experts in geriatrics and infectious diseases to review recent literature regarding UTIs in the PALTC population. The workgroup used evidence as well as their collective clinical expertise to develop this consensus statement with the goal of providing comprehensive guidance on the diagnosis, treatment, and prevention of UTIs in PALTC residents. The recommendations acknowledge limitations inherent to providing medical care for frail older adults, practicing within a resource limited setting, and prevention strategies tailored to PALTC populations. In addition, the consensus statement encourages integrating antibiotic stewardship principles into the policies and procedures used by PALTC nursing staff and by prescribing clinicians as they care for residents with a suspected UTI.

BACKGROUND: Procalcitonin (PCT) guidance alone or in conjunction with antibiotic stewardship programs (ASP) has been shown to reduce antibiotic utilization and duration of therapy without adversely affecting patient outcomes. METHODS: In a community hospital, we investigated the impact of PCT with ASP recommendations on length of stay (LOS), length of antimicrobial therapy (LOT) after ASP recommendation, and total LOT over a one-year period. Adult patients with at least one PCT value and concomitant ASP recommendations were included. Patients were grouped by provider ASP compliance and further stratified by normal versus elevated PCT values. No specific PCT algorithm was utilized. RESULTS: A total of 857 patients were retrospectively analyzed. Physicians complied with 73.7% of ASP recommendations. There were no significant differences in LOS based on ASP compliance. Mean LOT after ASP recommendations and mean total LOT were significantly shorter (2.5 vs. 3.9 days, p<0.0001 and 5.1 vs. 6.6 days, p<0.0001, respectively) in the ASP complier group. When stratified by initial PCT levels, ASP compliers for patients with normal PCT levels had the shortest duration of therapy for all groups; among patients with elevated PCT levels, the duration of therapy was significantly shorter in the ASP compliant group (5.79 vs. 7.12 days, p<0.0111). When controlling for baseline differences in initial PCT levels, LOS was found to be marginally shorter in the ASP compliant group (p = 0.076). CONCLUSIONS: PCT-guided ASP physician recommendations, when accepted by providers, led to reduction in antimicrobial LOT in a community hospital. This benefit was extended across patient groups irrespective of initial PCT levels.

BACKGROUND: Asymptomatic bacteriuria in the elderly commonly results in antibiotic administration and, in turn, contributes to antimicrobial resistance, adverse drug events, and increased costs. This is a major problem in the long-term care facility (LTCF) setting, where residents frequently transition to and from the acute-care setting, often transporting drug-resistant organisms across the continuum of care. The goal of this study was to assess the feasibility and efficacy of antimicrobial stewardship programs (ASPs) targeting urinary tract infections (UTIs) at community LTCFs. METHODS: This was a quasi-experimental study targeting antibiotic prescriptions for UTI using time-series analysis with 6-month retrospective pre-intervention and 6-month intervention period at three community LTCFs. The ASP team (infectious diseases (ID) pharmacist and ID physician) performed weekly prospective audit and feedback of consecutive prescriptions for UTI. Loeb clinical consensus criteria were used to assess appropriateness of antibiotics; recommendations were communicated to the primary treating provider by the ID pharmacist. Resident outcomes were recorded at subsequent visits. Generalized estimating equations using segmented regression were used to evaluate the impact of the ASP intervention on rates of antibiotic prescribing and antibiotic resistance. RESULTS: One-hundred and four antibiotic prescriptions for UTI were evaluated during the intervention, and recommendations were made for change in therapy in 40 (38 %), out of which 10 (25 %) were implemented. Only eight (8 %) residents started on antibiotics for UTI met clinical criteria for antibiotic initiation. An immediate 26 % decrease in antibiotic prescriptions for UTI during the ASP was identified with a 6 % reduction continuing through the intervention period (95 % Confidence Interval ([CI)] for the difference: -8 to -3 %). Similarly, a 25 % immediate decrease in all antibiotic prescriptions was noted after introduction of the ASP with a 5 % reduction continuing throughout the intervention period (95 % CI: -8 to -2 %). No significant effect was noted on resistant organisms or Clostridium difficile. CONCLUSION: Weekly prospective audit and feedback ASP in three community LTCFs over 6 months resulted in antibiotic utilization decreases but many lost opportunities for intervention.
RESUMEN
Education, surveillance, and promotion of antimicrobial stewardship align with the goals of public health to prevent disease, promote health, and prolong life. Many US federal and state public health organizations are already engaged in antimicrobial stewardship activities. Healthcare providers are encouraged to work with public health officials on appropriate local antimicrobial stewardship strategies to attain the common goal of reducing antimicrobial resistance and preserving antimicrobials for future generations.

Rational antimicrobial use can be achieved through antimicrobial stewardship--a coordinated set of strategies designed to improve the appropriate use of antimicrobial agents. There are encouraging examples of antimicrobial stewardship programs from different parts of the world; however, the structure of these programs varies by hospital and country. In an effort to identify best practices in hospitals, we describe legislative requirements, antimicrobial stewardship program infrastructure, strategies and outcomes in 3 countries that have established programs--the United Kingdom, France, and the United States.

Inappropriate antimicrobial use and antimicrobial resistance persist across the healthcare continuum. Antimicrobial stewardship guidelines assist healthcare institutions in establishing antimicrobial stewardship programs but rely on infectious diseases expertise and leadership, which are not available in all settings. Despite this, many institutions have found ways to use available resources to perform stewardship activities, with improvements in antimicrobial use and reductions in resistance and cost. This article highlights success stories in nonuniversity hospital settings and proposes antimicrobial stewardship strategies that may be more feasible in settings with limited infectious diseases expertise, information technology, or financial resources.

We describe four solid-organ transplant recipients with donor-derived West Nile virus (WNV) infection (encephalitis 3, asymptomatic 1) from a common donor residing in a region of increased WNV activity. All four transplant recipients had molecular evidence of WNV infection in their serum and/or cerebrospinal fluid (CSF) by reverse transcription polymerase chain reaction (RT-PCR) testing. Serum from the organ donor was positive for WNV IgM but negative for WNV RNA, whereas his lymph node and spleen tissues tested positive for WNV by RT-PCR. Combination therapy included intravenous immunoglobulin (4 cases), interferon (3 cases), fresh frozen plasma with WNV IgG (2 cases), and ribavirin (1 case). Two of the four transplant recipients survived.Review of the 20 published cases of organ-derived WNV infection found that this infection is associated with a high incidence of neuroinvasive disease (70%) and severe morbidity and mortality (30%). Median time to onset of symptomatic WNV infection was 13 days after transplantation (range 5-37 days). Initial unexplained fever unresponsive to antibiotic therapy followed by rapid onset of neurologic deficits was the most common clinical presentation. Confirmation of infection was made by testing serum and CSF for both WNV RNA by RT-PCR and WNV IgM by serological assays. Treatment usually included supportive care, reduction of immunosuppression, and frequent intravenous immunoglobulin. The often negative results for WNV by current RT-PCR and serological assays and the absence of clinical signs of acute infection in donors contribute to the sporadic occurrence of donor-derived WNV infection. Potential organ donors should be assessed for unexplained fever and neurological symptoms, particularly if they reside in areas of increased WNV activity.
