RESUMEN
In 2023 and 2024, 3 vaccines were approved by the US Food and Drug Administration (FDA) against respiratory syncytial virus (RSV) in adults. In addition, the first long-acting RSV monoclonal antibody for infants and young children was approved. This review provides clinicians with practical guidance to navigate this new era of RSV prevention.

Background: Lack of access to timely, detailed antibiotic use data has limited ambulatory antibiotic stewardship efforts. Antibiotic utilization is tracked across ambulatory care sites and emergency departments (ED) within a large integrated health system. Methods: This is a retrospective cohort analysis from June 1, 2019 to May 31, 2020 comparing antibiotic prescribing for all patients with ICD-10 diagnosis codes for cystitis, otitis media, pharyngitis, sinusitis, and upper respiratory tract infections (URTIs) among five ambulatory care departments across northeast Ohio and southeast Florida locations: ED, Urgent Care (UC), On-Demand Telehealth (TEL), Pediatrics (PED), and Primary Care (PC). Results: A total of 261,947 encounters were included (ED:56,766, UC:92,749, TEL:8,783, PED:29,151, PC:74,498) for the treatment of cystitis (30,932), otitis media (22,094), pharyngitis (59,964), sinusitis (53,693), or URTI (95,264). The population was 63% female with a median age of 34.2 years [12.8-56.3]. A total of 17% of patients had documented penicillin allergies and 18% of patients with pharyngitis received Group A Streptococcus (GAS) testing. Antibiotics were prescribed in 44% of encounters (ED:21,746 [38%], UC:45,652 [49%], TEL:4,622 [53%], PED:10,909 [37%], PC:33,547 [45%]; P < 0.001). Guideline concordant antibiotics were prescribed in 65% of encounters (ED:14,338 [66%], UC:31,532 [69%], TEL:3,869 [84%], PED:8,212 [75%], PC:17,263 [51%]; P < 0.001). Conclusions: Observed rates of antibiotic and guideline concordant antibiotic prescribing were similar to national published rates of antibiotic prescribing in the ambulatory setting. The variability in antibiotic prescribing demonstrates opportunities for targeted outpatient stewardship efforts. Timely antibiotic tracking tools can facilitate ambulatory antimicrobial stewardship activities.
RESUMEN
BACKGROUND: In September 2018, pharmacy antimicrobial stewardship (AMS) services were expanded to include weekends at this academic medical center. Activities performed by AMS pharmacists on the weekends include blood culture rapid diagnostic (RDT) review, antiretroviral therapy (ART) review, prospective audit and feedback (PAF) utilizing clinical decision support, vancomycin dosing, and operational support. The purpose of this study was to assess the operational and clinical impact of these expanded AMS services. METHODS: This single-center, quasi-experimental study included data from weekends before (9/2017-11/2017) and after (9/2018-11/2018) implementation. The descriptive primary outcome was the number of activities completed for each AMS activity type in the post-implementation group only. Secondary outcomes were time to AMS opportunity resolution, time to escalation or de-escalation following PAF or RDT alert, time to resolution of miscellaneous AMS related opportunities, length of stay (LOS), and antimicrobial use outcomes. RESULTS: During the post-implementation period 1258 activities were completed, averaging 97/weekend. Inclusion criteria for time to resolution outcomes were met by 72 patients pre-implementation and 59 patients post. The median (IQR) time to AMS opportunity resolution decreased from 18.5 hours pre-intervention (7.7-35.7) to 8.5 hours post-intervention (IQR 1.8-14.0), p < 0.01. Time to escalation was 11.6 hours compared to 1.7 hours (p = 0.1), de-escalation 16.7 hours compared to 10.8 hours (p = 0.03), and miscellaneous opportunity 40.8 hours compared to 13.2 hours (p = 0.01). No differences were observed in LOS or antimicrobial use outcomes. CONCLUSION: Presence of pharmacist-driven weekend AMS services significantly reduced time to resolution of AMS opportunities. These data support the value of weekend AMS services.

PURPOSE OF REVIEW: Overutilization of antimicrobials is a known contributor to the development of antimicrobial resistance, which is a threat to global health. The goal of antimicrobial stewardship programs (ASPs) is to implement targeted interventions to reduce inappropriate antimicrobial prescribing and prevent development of antimicrobial resistance. We aim to review recently published literature focused on five categories of ASP interventions that have demonstrated success in optimizing appropriate antimicrobial use, improving patient outcomes, and fighting antimicrobial resistance. RECENT FINDINGS: In the past year, ASP interventions in the published literature have focused on minimizing duration of antimicrobial therapy for infectious syndromes, implementing novel methods for performing prospective audit and feedback, utilizing microbiology laboratory or rapid diagnostic tests to expedite diagnosis, leveraging clinical decision support and electronic medical record tools, and performing penicillin allergy assessment. While the majority of studies assessing ASP interventions do not assess changes in antimicrobial resistance, outcomes demonstrating improved appropriate antibiotic use have been used as a surrogate. Successful ASPs should seek to implement and evaluate novel interventions targeting improvement in antimicrobial prescribing. Such interventions are of critical importance to prevent further growth of antimicrobial resistance.
RESUMEN
OBJECTIVE: Respiratory viral polymerase chain reaction (RV PCR) tests assist in rapidly identifying viral pathogens and differentiating viral versus bacterial causes of pneumonia. Studies evaluating the use of RV PCR tests on antibiotic use in adults have demonstrated mixed results. We implemented an antimicrobial stewardship (ASP) intervention for patients with a positive RV PCR test result who were receiving broad-spectrum antibiotics and aimed to assess the impact on antibiotic usage. METHODS: Retrospective quasi-experimental study of adult hospitalized patients comparing time to antibiotic deescalation, duration of antibiotic therapy, and antiviral use preintervention (January-March 2016) and postintervention (January-March 2017). RESULTS: Of 172 ASP alerts reviewed, 55 (32%) were considered actionable. Of these, 47% of interventions were accepted. No significant difference was observed in median time to antibiotic deescalation (pre: 2.7 days vs post: 2.3 days, p=0.88). Time to discontinuation of antimicrobial therapy pre- and postintervention was reduced from 4 to 1.9 days (p=0.057) for piperacillin-tazobactam, from 2.7 to 1.8 days (p=0.75) for ceftriaxone, and from 3.6 to 2 days (p=0.4) for levofloxacin, respectively. Time to initiation of oseltamivir for influenza was significantly shorter in the postintervention group (pre: 11.3 hrs vs post: 3.6 hrs, p=0.02). CONCLUSION: A third of patients receiving broad-spectrum antibiotics with a positive RV PCR had an opportunity for antimicrobial optimization, although this did not translate into a significant impact on the time to antibiotic deescalation or overall antibiotic use. Combination of RV PCR results with biomarkers to rule out bacterial coinfections and chest radiographic findings may help enhance the likelihood of accepted antibiotic deescalation recommendations and represents an area of future research.

Prolonged turnaround time of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) test results may delay time to notification and treatment of test-positive patients and result in unnecessary antimicrobial use in test-negative patients. This quasi-experimental study evaluated the impact of NG/CT rapid diagnostic testing (RDT) in an urban emergency department (ED) on treatment appropriateness, time to notification, and cost. Patients tested in December 2013-January 2014 (traditional group, n=200) were compared with those in December 2014-January 2015 (RDT group, n=200). There was a significant increase in treatment appropriateness in the RDT group, 72.5% versus 60% (P=0.008) and time to results notification was significantly faster (median 17.4 versus 51.5hours, P=0.010). Availability of test result prior to discharge was associated with increased treatment appropriateness (odds ratio, 22.65 [95% confidence interval, 2.86-179.68]). The RDT would save approximately $37,000 annually. These results support the use of NG/CT RDT to expand antimicrobial stewardship efforts within the ED.
