Colchicine and macrolides: a cohort study of the risk of adverse outcomes associated with concomitant exposure.
The authors conducted a cohort study using electronic health records comparing encounters with colchicine plus a macrolide and colchicine with an antibiotic non-macrolide, then assessed the relationship between the two groups. They found that heart failure was more frequent in the colchicine plus a macrolide cohort and that there was also a higher mortality rate. As there is a significant increase in the risk of hepatic failure and mortality when colchicine is concomitantly administered with a macrolide, they concluded that colchicine should not be used concomitantly with these antibiotics or should be temporarily discontinued to avoid toxic levels of colchicine.

Variation by race in antibiotics prescribed for hospitalized patients with skin and soft tissue infections.
This cohort study examined antibiotics prescribed and variations by race among hospitalized patients with skin and soft tissue infections (SSTIs). A subanalysis of multisite, cross-sectional data collected through a national survey of acute care hospital groups within Vizient, Inc. considering adult inpatients treated for SSTIs was used. Of the 1242 adult inpatients included from 91 US hospitals, 45% were female, 18% were Black, and 69% were White with a mean age of 58 years. Penicillin allergy with hives was found in 23%, 19% with rash, and 18% with unknown effects, with allergy found more frequent in Black patients (23%) versus White (18%). Adjusting for multiple factors, White inpatients were at an increased risk of cefazolin use and decreased risk of clindamycin use compared with Black inpatients. Cefazolin use with less likely to be prescribed to Black inpatients than White inpatients and they were likely to be prescribed clindamycin. Cefazolin is considered a first-line SSTI treatment with clindamycin not recommended given frequent dosing and high potential for adverse effects including Clostridioides difficile infection (CDI). Although penicillin allergy is described as more prevalent among White patients, the authors observed an increased prevalence among Black inpatients compared with White inpatients treated for SSTI.

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.

Quantifying the breadth of antibiotic exposure in sepsis and suspected infection using spectrum scores.
The purpose of this retrospective cohort study was to apply a validated method to describe the level of antimicrobial coverage in a cohort of patients with suspected infection and sepsis. The researchers conducted the study across 21 hospitals with patients admitted to the hospital through the ED between January 1, 2012, to December 31, 2017, with suspected infection or sepsis and receiving antibiotics during hospitalization. The researchers quantified the level of antimicrobial coverage using the Spectrum Score, a numerical score from 0 to 64. Of 364,506 hospital admissions through the ED, researchers identified 43.6% with suspected infection and 56.4% with sepsis. Inpatient mortality was greater among those with sepsis (8.4%) compared to those with suspected infection (1.2%). Patients with sepsis had higher median global Spectrum Scores and additive Spectrum Scores compared to those with suspected infection. Increased Spectrum Scores were related with inpatient mortality, even after covariate adjustments. Spectrum Scores quantify the inconsistency in antibiotic level among individual patients, between suspected infection and sepsis groups, over the course of the hospitalization, and across infection sources.

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.

Postdischarge prophylactic antibiotics following mastectomy with and without breast reconstruction.
The authors investigated factors associated with post-discharge prophylactic antibiotic use after mastectomy with and without immediate reconstruction and the impact on surgical-site infection (SSI). They found that anti-methicillin-sensitive Staphylococcus aureus antibiotics were associated with decreased risk of SSI for patients who had mastectomy only and those who had mastectomy with immediate reconstruction. They concluded that the high numbers needed to treat suggest that potential benefits of post-discharge antibiotics should be weighed against potential harms associated with antibiotic overuse.

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.

Clinical decision support improves blood culture collection before intravenous antibiotic administration in the emergency department.
This paper discusses the outcomes of using a clinical decision support (CDS) tool that was implemented in emergency departments (EDs) for sepsis patients to remind healthcare staff to take blood cultures before administration of intravenous (IV) antibiotics. The study compared timely blood culture collection outcomes prior to IV antibiotics for 54,538 adult ED patients 1 year before and after a CDS intervention implementation in the electronic health record. The baseline phase found that 46.1% had blood cultures prior to IV antibiotics, compared to 58.8% after the intervention. The CDS improved blood culture collection rates without increasing overutilization.

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.

Quality of antibiotic prescribing in a large direct-to-patient telehealth program: an observational study.
This study looked at the quality of antibiotic prescribing in direct-to-patient (DTP) telehealth visits compared to primary care visits, retail clinics, urgent care, or emergency department (ED). Claims were examined for 2,400,198 visits who were continually enrolled with a large national health insurer during 2016-2017 and treated for acute respiratory infection (ARI), or for women uncomplicated UTI. For streptococcal pharyngitis, the authors further measured whether a culture or rapid Group A Streptococcus test was done. Antibiotic prescription management for ARIs and UTIs was guideline-concordant comparable between televisits and several other settings. Patients with pharyngitis who received antibiotics were less likely to receive rapid Strep testing for televisits compared with primary care, retail clinics, urgent care, and EDs.

Retrospective stratification of cephalosporin allergy label risk using validated penicillin allergy frameworks.
The purpose of this study was to validate whether a history-based risk criteria used for penicillin allergy labels (PALs) is applicable to cephalosporin allergy labels (CALs), or whether there are additional features that require evaluation. From 2014 to 2019, the researchers evaluated a total of 322 patients with a total of 384 CALs in their outpatient drug allergy clinic for a completion of skin testing or a direct oral challenge. A total of 77.1% of patients had a negative testing result and were challenged. A total of 99.1% oral challenges were tolerated, leading to label removal, with 2 failures. 4.9% of patients had negative skin testing results and were delabeled afterward due to reported tolerance of a relevant cephalosporin since their index reaction. 5.6% of patients with negative skin testing result did not undergo oral challenge initially, but subsequently tolerated a cephalosporin treatment, which would trigger delabeling. Therefore, 94.8% of patients included for analysis had a complete cephalosporin allergy evaluation up to the level of either known tolerance or positive testing. Only 5.2% of included patients had complete, negative skin testing result and unknown tolerance of a challenge or treatment. The researchers concluded that history-based risk stratification of CALs appears to be acceptable using the existing validated criteria for penicillin allergy, with the additional note that a reported reaction to an IV cephalosporin may be inherently more likely to test positive, and should be evaluated more carefully.

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.

Early childhood antibiotic utilization for infants discharged from the neonatal intensive care unit.
The purpose of this retrospective observational study was to determine antibiotic use for Neonatal Intensive Care Unit (NICU) Infants in the first 3 years after birth hospital discharge. Using data for 667,541 newborns discharged from 2007-2011 from Medicaid Analytic Extract, the researchers assessed the relationships between NICU admission and antibiotic prescription. The study reported that 596,999 infants received one or more antibiotics, with a media of 4 prescriptions across 3 person-years. NICU infants (N = 81 314) received more antibiotic prescriptions compared to non-NICU infants. The study concluded that compared to non-NICU infants, antibiotic utilization in early childhood was higher among infants discharged from NICUs.

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.

Association of adverse events with antibiotic treatment for urinary tract infection.
The purpose of this study was to compare the risk of relative harms associated with different antibiotics prescribed for the treatment of uncomplicated urinary tract infection (UTI). The researchers identified 1,169,033 healthy, nonpregnant women between the ages of 18 to 44 who had an uncomplicated UTI and who initiated an oral antibiotic regimen for the treatment of common uropathogens between July 2006 and September 2015. The study found that of the two first-line treatments, the drug trimethoprim-sulfamethoxazole (versus nitrofurantoin) was associated with a higher risk of adverse drug-related events including: hypersensitivity, acute renal failure, skin rash, urticaria, abdominal pain, and nausea/ vomiting, but a similar risk of adverse possible microbiome-related events. When researchers compared non-first line drugs with nitrofurantoin, the non-first line drugs were associated with a greater risk of adverse drug events and possible microbiome-related adverse events including non-Clostridium difficile diarrhea, C. difficile infection, vaginitis/vulvovaginal candidiasis, and pneumonia. The duration of the treatment influenced the risk of possible microbiome-related adverse events. The study concluded that the risk of adverse events differs widely by both antibiotic drug and duration of regimen.

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.
