Look-back and look-forward durations and the apparent appropriateness of ambulatory antibiotic prescribing.
Researchers assessed how the apparent appropriateness of antibiotic prescribing changes when using different look-back and look-forward periods. Classifying all ambulatory antibiotic prescriptions in the electronic health record of an integrated health care system as chronic, appropriate, potentially appropriate, inappropriate, or not associated with any diagnosis, they concluded that ambulatory programs and studies focused on appropriate or inappropriate antibiotic prescribing can reasonably use a short duration of association between an antibiotic prescription and diagnosis codes. They further indicated that programs and studies focused on potentially appropriate antibiotic prescribing might consider examining longer durations.

Antibiotic overuse after discharge from medical short-stay units.
This study investigated antibiotic overuse after discharge from medical short-stay units (SSUs). This cross-sectional study included patients hospitalized in 2 different medical SSUs with a total of 40 beds at a single academic medical center. Eligible adults were discharged with an oral antibiotic from either SSU from May 2018 to September 2019. Of 100 patients discharged from SSUs with antibiotics, 47 had a skin and soft-tissue infection (SSTI), 22 pneumonia, 21 UTI, and 10 had “other” infections. Overall, 78 cases (78%) were defined as overuse, including 39 of 47 of those treated for SSTI, 17 of 21 for UTI, and 14 of 22 for pneumonia. The most common types of overuse were excess duration and guideline discordant selection. Examples of factors influencing overuse included consultant recommendations, miscalculation of duration, and the need for source control procedure.

Antibiotic spectrum index: a new tool comparing antibiotic use in three NICUs.
This study looked at a new tool called the antibiotic spectrum index (ASI) which quantifies antibiotic exposure by relative antimicrobial activity, adding information to exposure measured by days of therapy (DOT). This index was tested with very low-birth-weight infants (VLBW, <1500g) in 3 level-4 NICUs for 2 years at 2 sites and for 1 year at a third site. The authors calculated the ASI per antibiotic days and DOT per patient days for all admitted VLBW infants <32 weeks gestational age. The site with the highest DOT per patient days was found to have the lowest ASI per antibiotic days and the site with the highest mortality and infection rates were found to have the highest ASI per antibiotic days. Antibiotic utilization varied by center.

Association between asthma status and prenatal antibiotic prescription fills among women in a Medicaid population.
The objective of this study was to assess the relationship between maternal asthma and outpatient prenatal antibiotic prescription fills to inform antibiotic stewardship. With data from the Tennessee Medicaid Program, findings showed that women with asthma had an increased risk of filling at least one prenatal antibiotic prescription and had an increased number of fills during pregnancy compared to women without asthma. These findings highlight that pregnant women with asthma disproportionately fill more antibiotic prescriptions during pregnancy.

Antibiotic stewardship strategies and their association with antibiotic overuse after hospital discharge: an analysis of the Reducing Overuse of Antibiotics at Discharge (ROAD) home framework.
Researchers sought to understand strategies to optimize antibiotic prescribing at discharge. Surveying Michigan hospitals on their antibiotic stewardship strategies for community-acquired pneumonia (CAP) and urinary tract infection (UTI), they found that the more stewardship strategies a hospital reported, the lower its antibiotic overuse at discharge.

Days of antibiotic spectrum coverage: a novel metric for inpatient antibiotic consumption.
The purpose of this study was to develop a novel metric for antibiotic consumption, days of antibiotic spectrum coverage (DASC), to address the limitations of the current benchmarking metric days of therapy (DOT). The researchers developed their spectrum scoring system by assessing 77 antibiotics in 16 categories of antibacterial activity and creating a cumulative daily antibiotic spectrum coverage (ASC) score. To compare hospital benchmarking using DOT and DASC, the researchers conducted a retrospective cohort study of adult patients admitted to acute care units within the Veterans Health Administration system in 2018. The study found little relationship between DOT per 1000 and DASC per DOT, suggesting that lower antibiotic consumption at a hospital does not necessarily mean more frequent use of narrow-spectrum antibiotics. The researchers concluded that DASC is a potential replacement for DOT.

A perfect storm: COVID-19 and antimicrobial resistance.
The purpose of this article was to discuss key factors that contributed to the impact of the COVID-19 pandemic on antimicrobial resistance (AMR) with an emphasis on lessons learned and next steps. The authors report that the pandemic strained healthcare systems worldwide and disrupted standard infection control and antimicrobial stewardship practices, which are essential to limit the spread of multidrug-resistant organisms and decrease selective pressure related to inappropriate or unnecessary antimicrobial therapy. Disruptions to these practices are compounded by the disproportionately long hospital and intensive care unit stays observed in critically ill COVID-19 patients, leading to secondary bacterial infections that are notoriously difficult to treat and increase the use of broad-spectrum antibiotics, which can drive resistance. The article further states that the pandemic has led to shortages in personal protective equipment, increased workload, and staffing issues, all of which have disrupted routine antimicrobial stewardship activities. The article concludes that COVID-19 pandemic has highlighted the need to develop new therapeutic interventions for infectious diseases that do not rely solely on antibiotics, and stresses the importance of incorporating the lessons learned from the COVID-19 pandemic into future efforts to combat AMR.

A statewide collaborative quality initiative to improve antibiotic duration and outcomes in patients hospitalized with uncomplicated community-acquired pneumonia.
Researchers sought to improve antibiotic duration for community-acquired pneumonia (CAP) across 41 hospitals participating in the Michigan Hospital Medicine Safety Consortium (HMS). They found that, across diverse hospitals, HMS participation was associated with more appropriate use of short-course therapy and fewer adverse events in hospitalized patients with uncomplicated CAP.

Temporal trends in antimicrobial prescribing during hospitalization for potential infection and sepsis.
This study examined whether the push to administer antimicrobials to prevent sepsis has increased antimicrobial use in general. This observational cohort study of hospitalized patients at 152 hospitals in 2 health care systems during 2013 to 2018 looked at almost 1.6 million patients (81% male), admitted via the emergency department with 2 or more systemic inflammatory response syndrome (SIRS) criteria. From 2013 to 2018 first antimicrobial administration to patients with sepsis decreased by 37 minutes. At the same time, antimicrobial use within 48 hours, days of antimicrobial therapy, and receipt of broad-spectrum coverage decreased among the broader cohort of patients with systemic inflammatory response syndrome (SIRS). This may have caused a decrease in in-hospital mortality, 30-day mortality, length of hospitalization, new MDR culture positivity, and new MDR blood culture positivity over the study period among both patients with sepsis and those with SIRS. For the overall hospital population there was no evidence that increasing antimicrobial timing for sepsis was associated with increasing antimicrobial use or impaired antimicrobial stewardship.

Assessment of changes in visits and antibiotic prescribing during the Agency for Healthcare Research and Quality Safety Program for Improving Antibiotic Use and the COVID-19 pandemic.
This cohort study evaluated the effectiveness of the AHRQ Safety Program for Improving Antibiotic Use aimed to improve antibiotic prescribing in ambulatory practices by engaging clinicians and staff to incorporate antibiotic stewardship into practice culture, communication, and decision-making. The study ran from December 2019 through November 2020. A total of 389 ambulatory care practices with over 6.5 million visits to 5483 clinicians were compared from the baseline to completion of the program. Participants included 82 primary care practices, 103 urgent care practices, 34 federally supported practices, 21 pediatric-only practices, 39 pediatric urgent care practices, 21 pediatric-only practices, and 14 other practice types. Of the 389 practices who completed the program, 75% submitted completed data. Visits per practice per month decreased from a mean of 1624 at baseline to a nadir of 906 early in the COVID-19 pandemic (April 2020) and were 1797 at the end of the program. Total antibiotic prescribing decreased from 18.2% of visits at baseline to 9.5% at completion of the program. Acute respiratory infection (ARI) visits per practice per month decreased from a baseline of 321 to a nadir of 76 early in the pandemic (May 2020) and gradually increased through completion of the program (n = 239). Antibiotic prescribing for ARIs decreased from 39.2% at baseline to 24.7% at completion of the program.

Association of diagnostic stewardship for blood cultures in critically ill children with culture rates, antibiotic use, and patient outcomes: results of the Bright STAR Collaborative.
The purpose of this AHRQ-funded prospective study was to assess the relationship between a 14-site PICU blood culture collaborative, the Bright STAR (Testing Stewardship for Antibiotic Reduction) collaborative, and culture rates, antibiotic use, and patient outcomes. The researchers collected data from each participating PICU across the United States and from the Children’s Hospital Association Pediatric Health Information System. The main outcome was blood culture rates, with secondary outcomes including: broad-spectrum antibiotic use and PICU rates of central line-associated bloodstream infection (CLABSI), Clostridioides difficile infection, readmission, length of stay, sepsis, severe sepsis/septic shock, and mortality. The study found that the blood culture rate preimplementation across the 14 PICUs was 149.4 per 1000 patient days per month, and the rate postimplementation was 100.5 for a 33% relative reduction postimplementation. For those same periods, the rate of antibiotic use decreased from 506 days per 1000 patient-days per month preimplementation to 440 days per 1000 patient-days per month postimplementation, which reflects a 13% relative reduction. Rates of CLABSI decreased from 1.8 to 1.1 per 1000 central venous line days per month, a 36% relative reduction. The variables of length of stay, readmission, sepsis, severe sepsis/septic shock, and mortality were similar before and after implementation. The researchers concluded that collaborative interventions can reduce blood culture and antibiotic use in the PICU.

Comparison of criteria for determining appropriateness of antibiotic prescribing in nursing homes.
Researchers studied the extent to which the revised McGeer and Loeb criteria overlap and can be used interchangeably for tracking antibiotic appropriateness in nursing homes. Using a cross-sectional chart review in 5 Wisconsin nursing homes, they found that levels of agreement between the revised McGeer and Loeb criteria were moderate for urinary tract infections, fair for skin and soft-tissue infections, and slight for respiratory tract infections. They concluded that agreement between the revised McGeer and Loeb criteria is limited, and that nursing homes should employ the revised McGeer and Loeb criteria for their intended purposes.

Reducing overuse of antibiotics at discharge home: a single-center mixed methods pilot study.
This article described a single-center, controlled pilot study of a pharmacist-facilitated antibiotic timeout prior to hospital discharge. The timeout addressed key elements of duration and was designed and implemented using iterative cycles with rapid feedback. The authors evaluated implementation outcomes related to feasibility, including usability, adherence, and acceptability. The pharmacists conducted 288 antibiotic timeouts with a mean duration of 2.5 minutes. Pharmacists recommended an antibiotic change in 25% of timeouts with 70% of recommended changes accepted by hospitalists. Barriers included unanticipated and weekend discharges. There were no differences in antibiotic use after discharge during the intervention compared to control services.

Improving vancomycin stewardship in critically ill children.
The purpose of this study was to describe a quality improvement intervention to reduce the use of vancomycin in a tertiary care Pediatric Intensive Care Unit. Over a period of 3 years, the researchers conducted 3 quality improvement (QI) interventions including 1) stakeholder education, 2) development of a consensus-based guideline for empiric vancomycin use, and 3) implementation of the guideline through clinical decision support. The study found that of 1276 episodes of suspected bacterial infection, a total of 19 cases of bacteremia (1.5%) due to organisms requiring vancomycin therapy were identified, including 6 MRSA bacteremias. Over the 3-year period of the QI project, overall vancomycin DOT per 1000 patient days in the PICU decreased from a baseline mean of 182 DOT per 1000 patient days to 109 DOT per 1000 patient days (a 40% reduction). The study concluded that the intervention reduced overall vancomycin use in the Pediatric Intensive Care Unit without evidence of harm.

Analysis of multiple bacterial species and antibiotic classes reveals large variation in the association between seasonal antibiotic use and resistance.
The purpose of this study was to evaluate the relationship between the seasonal use of 5 classes of antibiotics (penicillins, macrolides, quinolones, tetracyclines, and nitrofurans) and antibiotic resistance across 3 species of bacteria: Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. The study found seasonal peaks in use which varied by class, with resistance in all 9 species-antibiotic combinations peaking in the spring and winter. Resistance to all antibiotic classes had the highest correlation with the use of the macrolides and penicillins which were the winter peaking classes. The researchers concluded that antibiotic use strategies will not be equally effective across all species and all antibiotics, but instead selection for resistance across antibiotic classes may be governed by penicillins and macrolides, the most commonly prescribed classes of antibiotics.

Lack of association of post-discharge prophylactic antibiotics with decreased risk of surgical site infection following spinal fusion.
This study’s objective was to determine the prevalence and factors associated with post-discharge prophylactic antibiotic use after spinal fusion and whether use was associated with decreased risk of surgical site infection (SSI). The study cohort included persons aged 10-64 years undergoing 156,446 spinal fusion procedures between January 2010 and July 2015. Excluded patients included complicated cases and those coded for infection from 30 days before to 2 days after surgical admission. Outpatient oral antibiotic prescriptions were identified within 2 days of surgical discharge. ICD-9-CM diagnosis codes were used to identify SSI within 90 days of surgery. Post-discharge prophylactic antibiotics were used in 9223 surgeries. SSIs occurred after 2557 procedures (1.6%). Factors significantly associated with post-discharge antibiotic use included history of lymphoma, diabetes, 3-7 versus 1-2 vertebral levels fused, and non-infectious postoperative complications. Analysis showed antibiotic use was not associated with decreased SSI risk after spinal fusion.

Implementation of an antibiotic stewardship program in long-term care facilities across the US.
The purpose of this study was to determine if AHRQ’s Safety Program for Improving Antibiotic Use was associated with reductions in antibiotic use in long-term care (LTC) facilities in the US. Findings showed that participation in the AHRQ safety program was associated with the development of antibiotic stewardship programs (ASPs) that actively engaged clinical staff in the decision-making processes around antibiotic prescriptions in participating LTC facilities. The reduction in days of antibiotic therapy and starts, which was more pronounced in more engaged facilities, indicated that implementation of this multifaceted program may support successful ASPs in LTC settings.

Introducing antimicrobial stewardship to the outpatient clinics of a suburban academic health system.
This study’s objective was to determine attitudes of prescribers of antimicrobials to help establish an antimicrobial stewardship program in the outpatient setting. Participants included prescribers at Loyola University Health System, an academic teaching healthcare system with 19 primary care and 3 intermediate- and urgent-care clinics. A voluntary survey was developed using SurveyMonkey and was distributed via email. Data were conducted anonymously. Three metrics were assessed for rates of compliance and included: (1) avoidance of antibiotics in adult acute bronchitis and appropriate antibiotic treatment in (2) patients tested for pharyngitis and (3) children with upper respiratory tract infections. Prescribers were very knowledgeable about what constitutes appropriate prescribing, but fewer than half believed antibiotics were overprescribed in their office. The respondents reported that 74% received intense pressure from patients to prescribe antimicrobials inappropriately. Intermediate- and urgent-care prescribers had higher rates of compliance than primary-care prescribers. However, the latter group responded well to monthly reports and online educational resources.

Development of an electronic definition for de-escalation of antibiotics in hospitalized patients.
The authors defined antibiotic de-escalation as reduction in either the number of antibiotics or spectrum rank and performed a retrospective study among 5 hospitals. They found that their electronic de-escalation metric demonstrated variation among hospitals, units, and diagnoses. They suggested that their metric may be useful for assessing stewardship opportunities and impact.

Electronically available patient claims data improve models for comparing antibiotic use across hospitals: results from 576 U.S. facilities.
This study’s goal was to identify comorbidities causally related to appropriate antibiotic use and to compare seven models that include these comorbidities and other patient-level claims variables to a facility model for risk-adjusting inpatient antibiotic utilization. Subjects included adults discharged from Premier Database hospitals in 2016-2017. Findings showed that adding electronically available patient claims data to facility models consistently improved antibiotic utilization predictions and yielded substantial movement in hospitals' utilization rankings.
