RESUMEN
OBJECTIVES: To assess and compare subsequent hospital admissions within 30 days for patients after receiving a prescription for either oral nirmatrelvir/ritonavir or oral molnupiravir. METHODS: We conducted a retrospective review of 3207 high-risk, non-hospitalized adult COVID-19 patients who received a prescription for molnupiravir (nâ=â209) or nirmatrelvir/ritonavir (nâ=â2998) at an academic medical centre in New York City from April to December 2022. Variables including age, vaccination status, high-risk conditions and demographic factors were pulled from the electronic medical record. We used multivariable logistic regression to adjust for potential confounding variables. RESULTS: All-cause 30 day hospitalization was not significantly different between patients who received nirmatrelvir/ritonavir compared with molnupiravir (1.4% versus 1.9%, P valueâ=â0.55). The association between COVID-related hospitalization and medication was also not significant (0.7%versus 0.5%, P valueâ=â0.99). Patients who received molnupiravir were more likely to have more underlying high-risk conditions. After adjusting for potential confounders, the odds of all-cause hospitalizations were not significantly different between patients who received nirmatrelvir/ritonavir compared with molnupiravir (ORâ=â1.16, 95% CI: 0.4-3.3, P valueâ=â0.79). CONCLUSIONS: These data provide additional evidence to support molnupiravir as a suitable alternative when other COVID-19 antivirals cannot be given.

BACKGROUND: Monoclonal antibodies (mAb) prevent COVID-19 progression when administered early. We compared mAb treatment outcomes among vaccinated and unvaccinated patients during Delta wave and assessed the feasibility of implementing stricter eligibility criteria in the event of mAb scarcity. METHODS: We conducted a retrospective observational study of casirivimab/imdevimab recipients with mild-to-moderate COVID-19 infection in an emergency department or outpatient infusion center (July 1-August 20, 2021). Primary outcome was all-cause hospital admission within 30 days post-treatment between vaccinated vs. unvaccinated patients during Delta surge in the Bronx, NY. RESULTS: A total of 250 patients received casirivimab/imdevimab (162 unvaccinated vs. 88 vaccinated). The median age was 39 years for unvaccinated patients, and 52 years for vaccinated patients (p < 0.0001). The median number of EUA criteria met was 1 for unvaccinated and 2 for vaccinated patients (p < 0.0001). Overall, 6% (15/250) of patients were admitted within 30 days post-treatment. Eleven unvaccinated patients (7%) were admitted within 30-days compared to 4 (5%) vaccinated patients (p = 0.48). CONCLUSIONS: All-cause 30-day admission was not statistically different between vaccinated and unvaccinated patients. When federal allocation of therapies is limited, programs must prioritize patients at highest risk of hospitalization and death regardless of vaccination status.

Background: Treatment of invasive gram-positive infections in complex patient populations is challenging. Dalbavancin, approved for skin and soft tissue infections, offers advantages in this setting due to its long half-life and infrequent dosing. However, less is known about the outcomes of off-label dalbavancin for deeper infections. Objectives: The objective of this study is to examine the feasibility and outcomes of patients with complex gram-positive infections treated with dalbavancin as an alternative to standard outpatient parenteral antimicrobial therapy (OPAT). Methods: We conducted a multicenter, retrospective review of adult patients managed within an OPAT program with intravenous dalbavancin for off-label indications. Adult patients were included if they had treatment details and follow-up documented between January 2020 and June 2023. Details of dalbavancin use including indications for prescription were captured. Outcomes of interest included 90-day infection recurrence, prosthesis retention rates, 90-day mortality, and adverse medication events. Results: In all, 61 patients received dalbavancin, mostly as sequential therapy. Twenty-three percent received dalbavancin strictly in the outpatient setting. Dalbavancin was used primarily for hardware (fracture, spine, or joint), native bone or joint, and complicated soft tissue infections. The predominant pathogen was Staphylococcus aureus (61%). Dalbavancin was frequently prescribed as a two-dose 1500 mg regimen (49%) due to persistent infection (23%), difficult line access (30%), difficulty achieving therapeutic vancomycin levels (18%), or substance abuse history (18%). Overall, six patients (10%) had infection recurrence and no patients died during the follow-up period. Three of eight patients with hardware retention had infection recurrence. Adverse effects were minimal and mostly self-limiting. Conclusion: Dalbavancin is an efficacious and safe alternative to standard OPAT, especially in those with barriers to traditional long-term intravenous antibiotics. Improved outcomes may be achieved with hardware removal. Dalbavancin may facilitate early discharge or prevent hospitalizations. Comparative studies of standard OPAT regimens versus dalbavancin are needed.
RESUMEN
PURPOSE: Infectious disease pharmacists and physicians overseeing antimicrobial stewardship programs possess expertise and often advanced certification in management of antiretrovirals to treat HIV. Stewardship programs are responsible for managing facility formularies and must stay up to date with the latest antiretrovirals, including once daily formulations and depot injectables. Furthermore, stewardship program members need to understand drug-interactions, short-, and long-term toxicities of these regimens, including dyslipidemia and cardiovascular effects. Patients receiving chronic antiretroviral therapy may present to the acute care, ambulatory care, and long-term care settings. Like other antimicrobials, audit-and-feedback, drug monitoring, and dose-optimization are often required to prevent antiretroviral associated medication errors and minimize resistance. METHODS: A narrative review was conducted on antiretroviral stewardship, addressing common clinical questions encountered by stewardship teams and best practices to optimize antiretroviral therapy and reduce the risk for treatment interruptions, resistance, drug interactions, long term toxicities, and other adverse effects. FINDINGS: People living with HIV are often hospitalized and treated by medical teams without formal HIV training. For this reason, these patients are at greater risk for medication errors during hospitalization and between transitions of care. Many opportunities are present for antiretroviral stewardship to mitigate these errors. Frequent updates to simplify HIV regimen, maintain select patients on fixed-dose combination tablets, and strategies to minimize drug interactions make it difficult for even the seasoned clinician to keep up regularly. IMPLICATIONS: Despite the availability of free online HIV resources and progress made in HIV management, significant opportunities for antiretroviral stewardship remain. Implementing electronic order entry updates, formulary upgrades, and formal pharmacy renal dose adjustments to optimize antiretroviral therapy will help clinicians harness these opportunities. Dedicated time and expertise for antiretroviral stewardship as part of local antimicrobial stewardship programs are needed.

Purpose: Outpatient antimicrobial stewardship programs (ASPs) are becoming increasingly prevalent in healthcare. Many programs have demonstrated the effectiveness of pharmacist-driven outpatient consultations or follow-up programs to ensure appropriate antimicrobial prescribing. However, there is a paucity of literature describing multidisciplinary approaches in large healthcare systems for patients discharged from the emergency department (ED). The objective of this study was to describe the feasibility and impact of a combined effort between ASP pharmacotherapy specialists and nurse practitioners (NPs) in managing an ED follow-up center. Methods: A retrospective analysis was conducted for patients discharged from the ED between January 2018 and June 2019. Patients were identified for inclusion based on documentation by ASP pharmacotherapy specialists in the electronic health record for patient-specific inquiries from ED follow-up center NPs. The primary outcome of this study was to describe the number and types of interventions made by ASP pharmacotherapy specialists. Results: A total of 1088 patients were included in the study, for 1114 documented ASP calls. The urinary tract was the most common source of positive culture (79%), and third-generation cephalosporins were the most frequent antibiotic associated with calls (20%). Out of total calls, 60% lead to ASP interventions. Among total calls, the most frequent interventions were to correct drug-bug mismatches (20%), initiate new therapy (10%), and discontinue therapy (7%). Conclusion: This report describes a novel initiative that combines the efforts of ED NPs and ASP pharmacotherapy specialists in managing an ED follow-up center at a large healthcare system.

Antimicrobial stewardship programs (ASPs) can be expanded to the outpatient setting to serve as a first line of defense against coronavirus disease 19 (COVID-19) hospitalizations and to reduce the burden on emergency departments and acute-care hospitals. Given the numerous emergency use authorizations of monoclonal antibodies and oral antivirals, ASPs possess the expertise and leadership to direct ambulatory COVID-19 initiatives and transform it into a predominantly outpatient illness. In this review, we summarize the critical role and benefits of an ASP-championed ambulatory COVID-19 therapeutics program.
RESUMEN
Our objectives were to evaluate the role of procalcitonin in identifying bacterial co-infections in hospitalized COVID-19 patients and quantify antibiotic prescribing during the 2020 pandemic surge. Hospitalized COVID-19 patients with both a procalcitonin test and blood or respiratory culture sent on admission were included in this retrospective study. Confirmed co-infection was determined by an infectious diseases specialist. In total, 819 patients were included; 335 (41%) had an elevated procalcitonin (>0.5 ng/mL) and of these, 42 (13%) had an initial bacterial co-infection. Positive predictive value of elevated procalcitonin for co-infection was 13% while the negative predictive value was 94%. Ninety-six percent of patients with an elevated procalcitonin received antibiotics (median 6 days of therapy), compared to 82% with low procalcitonin (median 4 days of therapy) (adjusted OR:3.3, P < 0.001). We observed elevated initial procalcitonin in many COVID patients without concurrent bacterial co-infections which potentially contributed to antibiotic over-prescribing.

OBJECTIVES: Secondary oral vancomycin prophylaxis (OVP) has been used in adults with a history of Clostridioides difficile infection (CDI) while receiving systemic antibiotics to prevent CDI recurrence. However, this practice has not been studied in pediatric patients. The objective of this study was to assess the utility of secondary OVP in pediatric patients with previous CDI who received subsequent antibiotic exposure. METHODS: A multicampus, retrospective cohort evaluation was conducted among patients aged ≤18 years with any history of clinical CDI and receiving systemic antibiotics in a subsequent encounter from 2013-2019. Patients who received concomitant OVP with antibiotics were compared with unexposed patients. The primary outcome was CDI recurrence within 8 weeks after antibiotic exposure. Infection with vancomycin-resistant enterococci and risk factors for CDI recurrence were assessed. RESULTS: A total of 148 patients were screened, of which 30 and 44 patients received OVP and no OVP, respectively. Patients who received OVP had greater antibiotic use and hospital lengths of stay. The incidence of CDI recurrence within 8 weeks of antibiotic exposure was significantly lower in patients who received OVP (3% vs 25%; P = .02) despite this group having notably more risk factors for recurrence. There were no vancomycin-resistant enterococci infections in any patients within either group. After adjustment in a multivariable analysis, secondary OVP was associated with less risk of recurrence (odds ratio, 0.10; 95% confidence interval, 0.01-0.86; P = .04). CONCLUSIONS: Secondary OVP while receiving systemic antibiotics reduces the risk of recurrent CDI in pediatric patients with a history of CDI.

Increasing posttreatment hospitalizations were observed monthly between December 2020 and March 2021 in parallel to the emergence of severe acute respiratory syndrome coronavirus 2 variants in New York City.
RESUMEN
PURPOSE: An overview of the growing health threat posed by the fungus Candida auris is provided, including a review of the literature and Centers for Disease Control and Prevention recommendations on C. auris identification, treatment, and infection control. SUMMARY: Since C. auris was first identified in Japan in 2009, cases of C. auris infection have been on the rise in several parts of the world, including the United States, where the first case was reported in 2017; as of November 2017, a total of 206 U.S. cases in 10 states had been reported. Risk factors for C. auris infection have been difficult to identify. However, catheterization, hospitalization, and recent surgery appear to be common factors in patients with C. auris infection. Major challenges in the management of C. auris infections include the common misidentification of C. auris using conventional laboratory techniques and the pathogen's resistance profile, which includes resistance to commonly used antifungals. These challenges may lead to breakdowns in timely implementation of infection-control and prevention measures. Antimicrobial stewardship can play a key role in the management and prevention of C. auris infections. CONCLUSION: C. auris is an emerging fungus that has the potential for causing serious invasive infections. The organism is resistant to commonly used antifungals and is difficult to identify with conventional laboratory techniques. Echinocandins are currently recommended as initial therapy for the treatment of C. auris infections in adults and children at least 2 months of age.
