Objectives: To assess rates of starting or stopping antibiotics across different hospitals. Methods: We used barcode medication administration data to measure antibiotic use on acute-care wards in 128 Veterans Affairs medical centres (VAMCs) in 2010. A treatment day (TD) was defined as the administration of any antibiotic on a given day. A treatment period (TP) was defined as an interval of inpatient antimicrobial therapy with gaps of ≤1 day in TDs. The rate of starting antibiotics was calculated for inpatients who had not yet started antibiotics, as the number of start events divided by the 'person-time at risk'. The rate of stopping antibiotics was calculated analogously for inpatients that were on antibiotics. Once individuals had stopped antibiotics they were removed from further analysis. Per-day start and stop rates were also calculated for each day of hospitalization. Results: The hospital mean rate of starting the first TP was 18.1 start events/100 days at risk (range 8.4-25.6/100 days at risk). The mean hospital stopping rate was 21.1 stop events/100 days at risk (range 13.3-29.5/100 days at risk). The ratio of a facility's starting and stopping rates was highly correlated with overall antibiotic use in TDs/1000 patient-days (rs=0.92, P

- Abstract
Importance: Urinary tract infection (UTI) is the second most common infection leading to hospitalization and is often associated with gram-negative multidrug-resistant organisms (MDROs). Clinicians overuse extended-spectrum antibiotics although most patients are at low risk for MDRO infection. Safe strategies to limit overuse of empiric antibiotics are needed., Objective: To evaluate whether computerized provider order entry (CPOE) prompts providing patient- and pathogen-specific MDRO risk estimates could reduce use of empiric extended-spectrum antibiotics for treatment of UTI., Design, Setting, and Participants: Cluster-randomized trial in 59 US community hospitals comparing the effect of a CPOE stewardship bundle (education, feedback, and real-time and risk-based CPOE prompts; 29 hospitals) vs routine stewardship (n = 30 hospitals) on antibiotic selection during the first 3 hospital days (empiric period) in noncritically ill adults (≥18 years) hospitalized with UTI with an 18-month baseline (April 1, 2017-September 30, 2018) and 15-month intervention period (April 1, 2019-June 30, 2020)., Interventions: CPOE prompts recommending empiric standard-spectrum antibiotics in patients ordered to receive extended-spectrum antibiotics who have low estimated absolute risk (<10%) of MDRO UTI, coupled with feedback and education., Main Outcomes and Measures: The primary outcome was empiric (first 3 days of hospitalization) extended-spectrum antibiotic days of therapy. Secondary outcomes included empiric vancomycin and antipseudomonal days of therapy. Safety outcomes included days to intensive care unit (ICU) transfer and hospital length of stay. Outcomes were assessed using generalized linear mixed-effect models to assess differences between the baseline and intervention periods., Results: Among 127 403 adult patients (71 991 baseline and 55 412 intervention period) admitted with UTI in 59 hospitals, the mean (SD) age was 69.4 (17.9) years, 30.5% were male, and the median Elixhauser Comorbidity Index count was 4 (IQR, 2-5). Compared with routine stewardship, the group using CPOE prompts had a 17.4% (95% CI, 11.2%-23.2%) reduction in empiric extended-spectrum days of therapy (rate ratio, 0.83 [95% CI, 0.77-0.89]; P < .001). The safety outcomes of mean days to ICU transfer (6.6 vs 7.0 days) and hospital length of stay (6.3 vs 6.5 days) did not differ significantly between the routine and intervention groups, respectively., Conclusions and Relevance: Compared with routine stewardship, CPOE prompts providing real-time recommendations for standard-spectrum antibiotics for patients with low MDRO risk coupled with feedback and education significantly reduced empiric extended-spectrum antibiotic use among noncritically ill adults admitted with UTI without changing hospital length of stay or days to ICU transfers., Trial Registration: ClinicalTrials.gov Identifier: NCT03697096.

- Abstract
Importance: Pneumonia is the most common infection requiring hospitalization and is a major reason for overuse of extended-spectrum antibiotics. Despite low risk of multidrug-resistant organism (MDRO) infection, clinical uncertainty often drives initial antibiotic selection. Strategies to limit empiric antibiotic overuse for patients with pneumonia are needed., Objective: To evaluate whether computerized provider order entry (CPOE) prompts providing patient- and pathogen-specific MDRO infection risk estimates could reduce empiric extended-spectrum antibiotics for non-critically ill patients admitted with pneumonia., Design, Setting, and Participants: Cluster-randomized trial in 59 US community hospitals comparing the effect of a CPOE stewardship bundle (education, feedback, and real-time MDRO risk-based CPOE prompts; n = 29 hospitals) vs routine stewardship (n = 30 hospitals) on antibiotic selection during the first 3 hospital days (empiric period) in non-critically ill adults (≥18 years) hospitalized with pneumonia. There was an 18-month baseline period from April 1, 2017, to September 30, 2018, and a 15-month intervention period from April 1, 2019, to June 30, 2020., Intervention: CPOE prompts recommending standard-spectrum antibiotics in patients ordered to receive extended-spectrum antibiotics during the empiric period who have low estimated absolute risk (<10%) of MDRO pneumonia, coupled with feedback and education., Main Outcomes and Measures: The primary outcome was empiric (first 3 days of hospitalization) extended-spectrum antibiotic days of therapy. Secondary outcomes included empiric vancomycin and antipseudomonal days of therapy and safety outcomes included days to intensive care unit (ICU) transfer and hospital length of stay. Outcomes compared differences between baseline and intervention periods across strategies., Results: Among 59 hospitals with 96 451 (51 671 in the baseline period and 44 780 in the intervention period) adult patients admitted with pneumonia, the mean (SD) age of patients was 68.1 (17.0) years, 48.1% were men, and the median (IQR) Elixhauser comorbidity count was 4 (2-6). Compared with routine stewardship, the group using CPOE prompts had a 28.4% reduction in empiric extended-spectrum days of therapy (rate ratio, 0.72 [95% CI, 0.66-0.78]; P < .001). Safety outcomes of mean days to ICU transfer (6.5 vs 7.1 days) and hospital length of stay (6.8 vs 7.1 days) did not differ significantly between the routine and CPOE intervention groups., Conclusions and Relevance: Empiric extended-spectrum antibiotic use was significantly lower among adults admitted with pneumonia to non-ICU settings in hospitals using education, feedback, and CPOE prompts recommending standard-spectrum antibiotics for patients at low risk of MDRO infection, compared with routine stewardship practices. Hospital length of stay and days to ICU transfer were unchanged., Trial Registration: ClinicalTrials.gov Identifier: NCT03697070.

- Abstract
Objective: The 2014 US National Strategy for Combating Antibiotic-Resistant Bacteria (CARB) aimed to reduce inappropriate inpatient antibiotic use by 20% for monitored conditions, such as community-acquired pneumonia (CAP), by 2020. We evaluated annual trends in length of therapy (LOT) in adults hospitalized with uncomplicated CAP from 2013 through 2020., Methods: We conducted a retrospective cohort study among adults with a primary diagnosis of bacterial or unspecified pneumonia using International Classification of Diseases Ninth and Tenth Revision codes in MarketScan and the Centers for Medicare & Medicaid Services databases. We included patients with length of stay (LOS) of 2-10 days, discharged home with self-care, and not rehospitalized in the 3 days following discharge. We estimated inpatient LOT based on LOS from the PINC AI Healthcare Database. The total LOT was calculated by summing estimated inpatient LOT and actual postdischarge LOT. We examined trends from 2013 to 2020 in patients with total LOT >7 days, which was considered an indicator of likely excessive LOT., Results: There were 44,976 and 400,928 uncomplicated CAP hospitalizations among patients aged 18-64 years and ≥65 years, respectively. From 2013 to 2020, the proportion of patients with total LOT >7 days decreased by 25% (68% to 51%) among patients aged 18-64 years and by 27% (68%-50%) among patients aged ≥65 years., Conclusions: Although likely excessive LOT for uncomplicated CAP patients decreased since 2013, the proportion of patients treated with LOT >7 days still exceeded 50% in 2020. Antibiotic stewardship programs should continue to pursue interventions to reduce likely excessive LOT for common infections.

- Abstract
Background: In 2014, the Centers for Disease Control and Prevention (CDC) released the Core Elements of Hospital Antibiotic Stewardship Programs (ASPs) and began monitoring uptake through the National Healthcare Safety Network (NHSN) Annual Hospital Survey. In 2019, CDC updated the Core Elements and in 2022 released the Priorities for Hospital Core Element Implementation. We describe Core Element uptake from 2014 to 2021, provide a snapshot of specific ASP practices in acute care hospitals in 2021, and describe how we plan to monitor stewardship moving forward., Methods: We used the NHSN Annual Hospital Survey to summarize facility demographics and ASP practices and to monitor uptake of Core Elements. Questions have been updated over time, so not all data could be compared across years., Results: Uptake of all 7 Core Elements increased from 41% in 2014 to 95% in 2021. Uptake of all 6 Priority Elements was 10% in 2021, though 46% of hospitals met 4 or 5 of the possible 6 elements. Antibiotic stewardship was specifically listed in a contract or job description for about 60% of program leaders. The percentage of physician-pharmacist co-led programs rose from 23% to 64%. Seventy-six percent of hospitals reported implementing audit with feedback interventions., Conclusions: With nearly all acute care hospitals reporting uptake of the 7 Core Elements in 2021, and with more evidence for which ASP practices are most effective, the Priorities for Hospital Core Element Implementation were released in 2022 to help enhance the quality and impact of existing ASPs., Competing Interests: Potential conflicts of interest. The authors: No reported conflicts of interest., (Published by Oxford University Press on behalf of Infectious Diseases Society of America 2024.)

- Abstract
Antimicrobial resistance remains a significant global public health threat. Although development of novel antibiotics can be challenging, several new antibiotics with improved activity against multidrug-resistant Gram-negative organisms have recently been commercialised. Expanding access to these antibiotics is a global public health priority that should be coupled with improving access to quality diagnostics, health care with adequately trained professionals, and functional antimicrobial stewardship programmes. This comprehensive approach is essential to ensure responsible use of these new antibiotics., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 World Health Organization.

- Abstract
Objective: To determine the proportion of hospitals that implemented 6 leading practices in their antimicrobial stewardship programs (ASPs). Design: Cross-sectional observational survey., Setting: Acute-care hospitals., Participants: ASP leaders., Methods: Advance letters and electronic questionnaires were initiated February 2020. Primary outcomes were percentage of hospitals that (1) implemented facility-specific treatment guidelines (FSTG); (2) performed interactive prospective audit and feedback (PAF) either face-to-face or by telephone; (3) optimized diagnostic testing; (4) measured antibiotic utilization; (5) measured C. difficile infection (CDI); and (6) measured adherence to FSTGs., Results: Of 948 hospitals invited, 288 (30.4%) completed the questionnaire. Among them, 82 (28.5%) had <99 beds, 162 (56.3%) had 100-399 beds, and 44 (15.2%) had ≥400+ beds. Also, 230 (79.9%) were healthcare system members. Moreover, 161 hospitals (54.8%) reported implementing FSTGs; 214 (72.4%) performed interactive PAF; 105 (34.9%) implemented procedures to optimize diagnostic testing; 235 (79.8%) measured antibiotic utilization; 258 (88.2%) measured CDI; and 110 (37.1%) measured FSTG adherence. Small hospitals performed less interactive PAF (61.0%; P = .0018). Small and nonsystem hospitals were less likely to optimize diagnostic testing: 25.2% (P = .030) and 21.0% (P = .0077), respectively. Small hospitals were less likely to measure antibiotic utilization (67.8%; P = .0010) and CDI (80.3%; P = .0038). Nonsystem hospitals were less likely to implement FSTGs (34.3%; P < .001)., Conclusions: Significant variation exists in the adoption of ASP leading practices. A minority of hospitals have taken action to optimize diagnostic testing and measure adherence to FSTGs. Additional efforts are needed to expand adoption of leading practices across all acute-care hospitals with the greatest need in smaller hospitals.

- Abstract
Background: A major challenge for antibiotic stewardship programs is the lack of accurate and accessible electronic data to target interventions. We developed and validated separate electronic algorithms to identify inappropriate antibiotic use for adult outpatients with bronchitis and pharyngitis., Methods: We used International Classification of Diseases, 10th Revision, diagnostic codes to identify patient encounters for acute bronchitis and pharyngitis at outpatient practices between 3/15/17 and 3/14/18. Exclusion criteria included immunocompromising conditions, complex chronic conditions, and concurrent infections. We randomly selected 300 eligible subjects each with bronchitis and pharyngitis. Inappropriate antibiotic use based on chart review served as the gold standard for assessment of the electronic algorithm, which was constructed using only data in the electronic data warehouse. Criteria for appropriate prescribing, choice of antibiotic, and duration were based on established guidelines., Results: Of 300 subjects with bronchitis, 167 (55.7%) received an antibiotic inappropriately based on chart review. The electronic algorithm demonstrated 100% sensitivity and 95.3% specificity for detection of inappropriate prescribing. Of 300 subjects with pharyngitis, 94 (31.3%) had an incorrect prescribing decision. Among 29 subjects with a positive rapid streptococcal antigen test, 27 (93.1%) received an appropriate antibiotic and 29 (100%) received the correct duration. The electronic algorithm demonstrated very high sensitivity and specificity for all outcomes., Conclusions: Inappropriate antibiotic prescribing for bronchitis and pharyngitis is common. Electronic algorithms for identifying inappropriate prescribing, antibiotic choice, and duration showed excellent test characteristics. These algorithms could be used to efficiently assess prescribing among practices and individual clinicians. Interventions based on these algorithms should be tested in future work., (© The Author(s) 2022. Published by Oxford University Press on behalf of the Infectious Diseases Society of America.)

- Abstract
Importance: Although prescribers face numerous patient-centered challenges during transitions of care (TOC) at hospital discharge, prolonged duration of antimicrobial therapy for common infections remains problematic, and resources are needed for antimicrobial stewardship throughout this period., Objective: To evaluate a pharmacist-driven intervention designed to improve selection and duration of oral antimicrobial therapy prescribed at hospital discharge for common infections., Design, Setting, and Participants: This quality improvement study used a nonrandomized stepped-wedge design with 3 study phases from September 1, 2018, to August 31, 2019. Seventeen distinct medicine, surgery, and specialty units from a health system in Southeast Michigan participated, including 1 academic tertiary hospital and 4 community hospitals. Hospitalized adults who had urinary, respiratory, skin and/or soft tissue, and intra-abdominal infections and were prescribed antimicrobials at discharge were included in the analysis. Data were analyzed from February 18, 2020, to February 28, 2022., Interventions: Clinical pharmacists engaged in a new standard of care for antimicrobial stewardship practices during TOC by identifying patients to be discharged with a prescription for oral antimicrobials and collaborating with primary teams to prescribe optimal therapy. Academic and community hospitals used both antimicrobial stewardship and clinical pharmacists in a multidisciplinary rounding model to discuss, document, and facilitate order entry of the antimicrobial prescription at discharge., Main Outcomes and Measures: The primary end point was frequency of optimized antimicrobial prescription at discharge. Health system guidelines developed from national guidelines and best practices for short-course therapies were used to evaluate optimal therapy., Results: A total of 800 patients prescribed oral antimicrobials at hospital discharge were included in the analysis (441 women [55.1%]; mean [SD] age, 66.8 [17.3] years): 400 in the preintervention period and 400 in the postintervention period. The most common diagnoses were pneumonia (264 [33.0%]), upper respiratory tract infection and/or acute exacerbation of chronic obstructive pulmonary disease (214 [26.8%]), and urinary tract infection (203 [25.4%]). Patients in the postintervention group were more likely to have an optimal antimicrobial prescription (time-adjusted generalized estimating equation odds ratio, 5.63 [95% CI, 3.69-8.60]). The absolute increase in optimal prescribing in the postintervention group was consistent in both academic (37.4% [95% CI, 27.5%-46.7%]) and community (43.2% [95% CI, 32.4%-52.8%]) TOC models. There were no differences in clinical resolution or mortality. Fewer severe antimicrobial-related adverse effects (time-adjusted generalized estimating equation odds ratio, 0.40 [95% CI, 0.18-0.88]) were identified in the postintervention (13 [3.2%]) compared with the preintervention (36 [9.0%]) groups., Conclusions and Relevance: The findings of this quality improvement study suggest that targeted antimicrobial stewardship interventions during TOC were associated with increased optimal, guideline-concordant antimicrobial prescriptions at discharge.

- Abstract
Background: The microbiologic etiologies, clinical manifestations, and antimicrobial treatment of neonatal infections differ substantially from infections in adult and pediatric patient populations. In 2019, the Centers for Disease Control and Prevention developed neonatal-specific (Standardized Antimicrobial Administration Ratios SAARs), a set of risk-adjusted antimicrobial use metrics that hospitals participating in the National Healthcare Safety Network's (NHSN's) antimicrobial use surveillance can use in their antibiotic stewardship programs (ASPs)., Methods: The Centers for Disease Control and Prevention, in collaboration with the Vermont Oxford Network, identified eligible patient care locations, defined SAAR agent categories, and implemented neonatal-specific NHSN Annual Hospital Survey questions to gather hospital-level data necessary for risk adjustment. SAAR predictive models were developed using 2018 data reported to NHSN from eligible neonatal units., Results: The 2018 baseline neonatal SAAR models were developed for 7 SAAR antimicrobial agent categories using data reported from 324 neonatal units in 304 unique hospitals. Final models were used to calculate predicted antimicrobial days, the SAAR denominator, for level II neonatal special care nurseries and level II/III, III, and IV NICUs., Conclusions: NHSN's initial set of neonatal SAARs provides a way for hospital ASPs to assess whether antimicrobial agents in their facility are used at significantly higher or lower rates compared with a national baseline or whether an individual SAAR value is above or below a specific percentile on a given SAAR distribution, which can prompt investigations into prescribing practices and inform ASP interventions., Competing Interests: CONFLICTS OF INTEREST DISCLOSURES: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2022 by the American Academy of Pediatrics.)

Importance: Hospital antimicrobial consumption data are widely available; however, large-scale assessments of the quality of antimicrobial use in US hospitals are limited., Objective: To evaluate the appropriateness of antimicrobial use for hospitalized patients treated for community-acquired pneumonia (CAP) or urinary tract infection (UTI) present at admission or for patients who had received fluoroquinolone or intravenous vancomycin treatment., Design, Setting, and Participants: This cross-sectional study included data from a prevalence survey of hospitalized patients in 10 Emerging Infections Program sites. Random samples of inpatients on hospital survey dates from May 1 to September 30, 2015, were identified. Medical record data were collected for eligible patients with 1 or more of 4 treatment events (CAP, UTI, fluoroquinolone treatment, or vancomycin treatment), which were selected on the basis of common infection types reported and antimicrobials given to patients in the prevalence survey. Data were analyzed from August 1, 2017, to May 31, 2020., Exposure: Antimicrobial treatment for CAP or UTI or with fluoroquinolones or vancomycin., Main Outcomes and Measures: The percentage of antimicrobial use that was supported by medical record data (including infection signs and symptoms, microbiology test results, and antimicrobial treatment duration) or for which some aspect of use was unsupported. Unsupported antimicrobial use was defined as (1) use of antimicrobials to which the pathogen was not susceptible, use in the absence of documented infection signs or symptoms, or use without supporting microbiologic data; (2) use of antimicrobials that deviated from recommended guidelines; or (3) use that exceeded the recommended duration., Results: Of 12 299 patients, 1566 patients (12.7%) in 192 hospitals were included; the median age was 67 years (interquartile range, 53-79 years), and 864 (55.2%) were female. A total of 219 patients (14.0%) were included in the CAP analysis, 452 (28.9%) in the UTI analysis, 550 (35.1%) in the fluoroquinolone analysis, and 403 (25.7%) in the vancomycin analysis; 58 patients (3.7%) were included in both fluoroquinolone and vancomycin analyses. Overall, treatment was unsupported for 876 of 1566 patients (55.9%; 95% CI, 53.5%-58.4%): 110 of 403 (27.3%) who received vancomycin, 256 of 550 (46.6%) who received fluoroquinolones, 347 of 452 (76.8%) with a diagnosis of UTI, and 174 of 219 (79.5%) with a diagnosis of CAP. Among patients with unsupported treatment, common reasons included excessive duration (103 of 174 patients with CAP [59.2%]) and lack of documented infection signs or symptoms (174 of 347 patients with UTI [50.1%])., Conclusions and Relevance: The findings suggest that standardized assessments of hospital antimicrobial prescribing quality can be used to estimate the appropriateness of antimicrobial use in large groups of hospitals. These assessments, performed over time, may inform evaluations of the effects of antimicrobial stewardship initiatives nationally.

- Abstract
Background: The Standardized Antimicrobial Administration Ratio (SAAR) is a risk-adjusted metric of antimicrobial use (AU) developed by the Centers for Disease Control and Prevention (CDC) in 2015 as a tool for hospital antimicrobial stewardship programs (ASPs) to track and compare AU with a national benchmark. In 2018, CDC updated the SAAR by expanding the locations and antimicrobial categories for which SAARs can be calculated and by modeling adult and pediatric locations separately., Methods: We identified eligible patient-care locations and defined SAAR antimicrobial categories. Predictive models were developed for eligible adult and pediatric patient-care locations using negative binomial regression applied to nationally aggregated AU data from locations reporting ≥9 months of 2017 data to the National Healthcare Safety Network (NHSN)., Results: 2017 Baseline SAAR models were developed for 7 adult and 8 pediatric SAAR antimicrobial categories using data reported from 2156 adult and 170 pediatric locations across 457 hospitals. The inclusion of step-down units and general hematology-oncology units in adult 2017 baseline SAAR models and the addition of SAARs for narrow-spectrum B-lactam agents, antifungals predominantly used for invasive candidiasis, antibacterial agents posing the highest risk for Clostridioides difficile infection, and azithromycin (pediatrics only) expand the role SAARs can play in ASP efforts. Final risk-adjusted models are used to calculate predicted antimicrobial days, the denominator of the SAAR, for 40 SAAR types displayed in NHSN., Conclusions: SAARs can be used as a metric to prompt investigation into potential overuse or underuse of antimicrobials and to evaluate the effectiveness of ASP interventions., (Published by Oxford University Press for the Infectious Diseases Society of America 2020.)

- Abstract
Background: The role of nurses in diagnostic stewardship in hospitals remains largely unknown., Methods: In this before-after study, researchers assessed the impact of a nurse-driven urine culture (UrCx) stewardship intervention for adults with and without urinary catheters on a general medicine unit of a large hospital. The intervention included education on principles of diagnostic stewardship, identification of a nurse champion to serve as liaison between nursing and the antibiotic stewardship program, and implementation of an algorithm to guide discussions with hospitalists about situations when UrCx may not be needed. The primary outcome was the total number of UrCx. The secondary outcome was the rate of inappropriate UrCx. Changes in UrCx rates per 100 patient-days before and after the intervention were calculated using incidence rate ratios (IRRs). Balancing metrics included readmission within 30 days of unit discharge, length of hospital stay, and all-cause in-hospital mortality., Results: With the intervention, the mean UrCx rate per 100 patient-days decreased from 2.30 to 1.52 (IRR = 0.66, 95% confidence interval [CI] = 0.50-0.87, p < 0.01), while in the control unit it increased from 2.17 to 3.10 (IRR = 1.50, 95% CI = 1.22-1.84, p < 0.01). In the intervention unit, the rate of inappropriate UrCx was 0.83 and 0.71 before and after algorithm implementation (IRR = 0.88, 95% CI = 0.58-1.33, p = 0.55)., Conclusion: Nursing education and a clinical tool to enhance discussions on the necessity of UrCx among nurses and hospitalists were associated with a reduction in UrCx., (Copyright © 2020 The Joint Commission.

- Abstract
Background: Skin and soft tissue infections (SSTIs) are a key antimicrobial stewardship target because they are a common infection in hospitalized patients, and non-guideline-concordant antibiotic use is frequent. To inform antimicrobial stewardship interventions, we evaluated the proportion of veterans hospitalized with SSTIs who received guideline-concordant empiric antibiotics or an appropriate total duration of antibiotics., Methods: A retrospective medication use evaluation was performed in 34 Veterans Affairs Medical Centers between 2016 and 2017. Hospitalized patients who received antibiotics for uncomplicated SSTI were included. Exclusion criteria were complicated SSTI, severe immunosuppression, and antibiotics for any non-SSTI indication. Data were collected by manual chart review. The primary outcome was the proportion of patients receiving both guideline-concordant empiric antibiotics and appropriate treatment duration, defined as 5-10 days of antibiotics. Data were analyzed and reported using descriptive statistics., Results: Of the 3890 patients manually evaluated for inclusion, 1828 patients met inclusion criteria. There were 1299 nonpurulent (71%) and 529 purulent SSTIs (29%). Overall, 250 patients (14%) received guideline-concordant empiric therapy and an appropriate duration. The most common reason for non-guideline-concordance was receipt of antibiotics targeting methicillin-resistant Staphylococcus aureus (MRSA) in 906 patients (70%) with a nonpurulent SSTI. Additionally, 819 patients (45%) received broad-spectrum Gram-negative coverage, and 860 patients (48%) received an antibiotic duration >10 days., Conclusions: We identified 3 common opportunities to improve antibiotic use for patients hospitalized with uncomplicated SSTIs: use of anti-MRSA antibiotics in patients with nonpurulent SSTIs, use of broad-spectrum Gram-negative antibiotics, and prolonged durations of therapy., (Published by Oxford University Press on behalf of Infectious Diseases Society of America 2020.)

- Abstract
The overuse and misuse of antibiotics affect patients in many ways, including by driving antibiotic resistance, a serious public health threat in the United States and around the world. To improve patient safety and address rising rates of resistance, an increasing number of health care facilities have created antibiotic stewardship programs (ASPs). ASPs have been successful in slowing the emergence of resistance and improving patient outcomes. However, there are serious geographic and resource barriers to ASP adoption in small community hospitals and critical access hospitals. Fortunately, many barriers can be overcome by using collaborative models to bring together key stakeholders, including large hospitals and health systems and academic medical centers; hospital associations; federal, state, and local public health organizations; and federal and state offices of rural health. These stakeholders are ideally positioned to assist with stewardship efforts in small community and critical access hospitals and, in doing so, can improve patient safety while stemming the spread of resistant bacteria.

- Abstract
The Joint Commission's hospital antimicrobial stewardship (AS) standards became effective in January 2017. Surveyors' experience to date suggests that almost all hospitals have established AS leadership commitment and organized structures. Thus, The Joint Commission sought to examine advances in AS interventions and measures that hospitals could implement to strengthen their existing AS programs., Methods: The Joint Commission and Pew Charitable Trusts sponsored a meeting to bring together experts and key stakeholder organizations from around the country to identify leading practices for AS interventions and measurement. Presenters were asked to summarize the AS activities they thought were most important for the success of their own AS program and leading practices that all hospitals should be able to implement., Results: The panel highlighted two interventions as leading practices that go beyond current guidelines and established practices (that is, preauthorization and prospective audit and feedback). The first is diagnostic stewardship. This type of intervention addresses errors in diagnostic decision making that lead to inappropriate antibiotic prescribing. The second is handshake stewardship, a method of engaging frontline providers on a regular basis for education and discussions about barriers to AS from the clinician's perspective. The panel identified days of therapy (or defined daily dose, when days of therapy is not possible), Clostridioides difficile rates, and adherence to facility-specific guidelines as the preferred measures for assessing stewardship activities., Conclusion: The practices highlighted should be given greater emphasis by The Joint Commission in their efforts to improve hospital AS, and the Centers for Disease Control and Prevention will be updating the Core Elements of Hospital Antibiotic Stewardship Programs., (Copyright © 2019.)

- Abstract
Background: The Antimicrobial Use (AU) Option of the Centers for Disease Control and Prevention's National Healthcare Safety Network (NHSN) is a surveillance resource that can provide actionable data for antibiotic stewardship programs. Such data are used to enable measurements of AU across hospitals and before, during, and after stewardship interventions., Methods: We used monthly AU data and annual facility survey data submitted to the NHSN to describe hospitals and neonatal patient care locations reporting to the AU Option in 2017, examine frequencies of most commonly reported agents, and analyze variability in AU rates across hospitals and levels of care. We used results from these analyses in a collaborative project with Vermont Oxford Network to develop neonatal-specific Standardized Antimicrobial Administration Ratio (SAAR) agent categories and neonatal-specific NHSN Annual Hospital Survey questions., Results: As of April 1, 2018, 351 US hospitals had submitted data to the AU Option from at least 1 neonatal unit. In 2017, ampicillin and gentamicin were the most frequently reported antimicrobial agents. On average, total rates of AU were highest in level III NICUs, followed by special care nurseries, level II-III NICUs, and well newborn nurseries. Seven antimicrobial categories for neonatal SAARs were created, and 6 annual hospital survey questions were developed., Conclusions: A small but growing percentage of US hospitals have submitted AU data from neonatal patient care locations to NHSN, enabling the use of AU data aggregated by NHSN as benchmarks for neonatal antimicrobial stewardship programs and further development of the SAAR summary measure for neonatal AU., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

- Abstract
Background: Antibiotics are overprescribed for acute respiratory tract infections (ARIs). Guidelines provide criteria to determine which patients should receive antibiotics. We assessed congruence between documentation of ARI diagnostic and treatment practices with guideline recommendations, treatment appropriateness, and outcomes., Methods: A multicenter quality improvement evaluation was conducted in 28 Veterans Affairs facilities. We included visits for pharyngitis, rhinosinusitis, bronchitis, and upper respiratory tract infections (URI-NOS) that occurred during the 2015-2016 winter season. A manual record review identified complicated cases, which were excluded. Data were extracted for visits meeting criteria, followed by analysis of practice patterns, guideline congruence, and outcomes., Results: Of 5,740 visits, 4,305 met our inclusion criteria: pharyngitis (n = 558), rhinosinusitis (n = 715), bronchitis (n = 1,155), URI-NOS (n = 1,475), or mixed diagnoses (>1 ARI diagnosis) (n = 402). Antibiotics were prescribed in 68% of visits: pharyngitis (69%), rhinosinusitis (89%), bronchitis (86%), URI-NOS (37%), and mixed diagnosis (86%). Streptococcal diagnostic testing was performed in 33% of pharyngitis visits; group A Streptococcus was identified in 3% of visits. Streptococcal tests were ordered less frequently for patients who received antibiotics (28%) than those who did not receive antibiotics 44%; P < .01). Although 68% of visits for rhinosinusitis had documentation of symptoms, only 32% met diagnostic criteria for antibiotics. Overall, 39% of patients with uncomplicated ARIs received appropriate antibiotic management. The proportion of 30-day return visits for ARI care was similar for appropriate (11%) or inappropriate (10%) antibiotic management (P = .22)., Conclusions: Antibiotics were prescribed in most uncomplicated ARI visits, indicating substantial overuse. Practice was frequently discordant with guideline diagnostic and treatment recommendations.

- Abstract
Background: To provide a standardized, risk-adjusted method for summarizing antibiotic use (AU), enable hospitals to track their AU over time and compare their AU data to national benchmarks, the Centers for Disease Control and Prevention developed the Standardized Antimicrobial Administration Ratio (SAAR)., Methods: Hospitals reporting to the National Healthcare Safety Network (NHSN) AU Option collect and submit aggregated AU data electronically as antimicrobial days of therapy per patient days present. SAARs were developed for specific NHSN adult and pediatric patient care locations and cover five antimicrobial agent categories: (1) broad-spectrum agents predominantly used for hospital-onset/multi-drug resistant bacteria; (2) broad-spectrum agents predominantly used for community-acquired infections; (3) anti-methicillin-resistant Staphylococcus aureus agents; (4) agents predominantly used for surgical site infection prophylaxis; and (5) all antibiotic agents. The SAAR is an observed-to-predicted use ratio where predicted use is estimated from a statistical model; a SAAR of 1 indicates that observed use and predicted use are equal., Results: Most location-level SAARs were statistically significantly different than 1: adult locations up to 52% lower than 1 and up to 41% higher than 1. Median SAARs in adult and pediatric ICUs had a range of 0.667-1.119. SAAR distributions serve as an external comparison to national SAARs., Conclusions: This is the first aggregate AU metric that uses point-of-care, antimicrobial administration data electronically reported to a national surveillance system to enable risk-adjusted, AU comparisons across multiple hospitals. Endorsed by the National Quality Forum, SAARs provide AU benchmarks that stewardship programs can use to help drive improvements.

- Abstract
Background: Electronic health records provide the opportunity to assess system-wide quality measures. Veterans Affairs Pharmacy Benefits Management Center for Medication Safety uses medication use evaluation (MUE) through manual review of the electronic health records., Objective: To compare an electronic MUE approach versus human/manual review for extraction of antibiotic use (choice and duration) and severity metrics., Research Design: Retrospective., Subjects: Hospitalizations for uncomplicated pneumonia occurring during 2013 at 30 Veterans Affairs facilities., Measures: We compared summary statistics, individual hospitalization-level agreement, facility-level consistency, and patterns of variation between electronic and manual MUE for initial severity, antibiotic choice, daily clinical stability, and antibiotic duration., Results: Among 2004 hospitalizations, electronic and manual abstraction methods showed high individual hospitalization-level agreement for initial severity measures (agreement=86%-98%, κ=0.5-0.82), antibiotic choice (agreement=89%-100%, κ=0.70-0.94), and facility-level consistency for empiric antibiotic choice (anti-MRSA r=0.97, P<0.001; antipseudomonal r=0.95, P<0.001) and therapy duration (r=0.77, P<0.001) but lower facility-level consistency for days to clinical stability (r=0.52, P=0.006) or excessive duration of therapy (r=0.55, P=0.005). Both methods identified widespread facility-level variation in antibiotic choice, but we found additional variation in manual estimation of excessive antibiotic duration and initial illness severity., Conclusions: Electronic and manual MUE agreed well for illness severity, antibiotic choice, and duration of therapy in pneumonia at both the individual and facility levels. Manual MUE showed additional reviewer-level variation in estimation of initial illness severity and excessive antibiotic use. Electronic MUE allows for reliable, scalable tracking of national patterns of antimicrobial use, enabling the examination of system-wide interventions to improve quality.

- Abstract
Purpose: The development and validation of a staffing calculator and its use in creating staffing guidance for antimicrobial stewardship programs (ASPs) in Veterans Health Administration (VHA) facilities are described., Methods: The Tools and Resources Work Group of the Antimicrobial Stewardship Task Force and PBM Clinical Pharmacy Practice Office of the Department of Veterans Affairs developed, tested, and validated a staffing calculator to track patient care and ASP management activities needed to maintain a comprehensive ASP. Time spent on activities was based on time-in-motion tracking studies and input from experienced antimicrobial stewards. The staffing calculator was validated across VHA facilities of varying sizes and complexities to determine the number of needed clinical pharmacist full-time equivalents (FTEs) to implement and maintain ASPs per 100 occupied beds., Results: A total of 12 facilities completed the staffing calculator for 1 calendar week. The median number of occupied beds was 226. Most facilities had at least 100 occupied beds, and 6 of the 12 were considered high complexity facilities. The median calculated FTE personnel requirement was 2.62, or 1.01 per 100 occupied beds. The majority of FTE time (70%) was spent on patient care activities and 30% on program management activities, including infectious diseases or ASP rounds. The final recommendations indicated that in order to implement and manage a robust ASP, a pharmacist FTE investment of 1.0 per 100 occupied beds would be needed., Conclusion: A staffing calculator to account for the time needed to implement ASP activities and provide staffing guidance across a large health-care system was validated., (Copyright © 2017 by the American Society of Health-System Pharmacists, Inc.

- Abstract
Background: Bacteriuria contributes to antibiotic overuse through treatment of asymptomatic bacteriuria (ASB) and long durations of therapy for symptomatic urinary tract infections (UTIs), yet large-scale evaluations of bacteriuria management among inpatients are lacking., Methods: Inpatients with bacteriuria were classified as asymptomatic or symptomatic based on established criteria applied to data collected by manual chart review. We examined frequency of treatment of ASB, factors associated with treatment of ASB, durations of therapy, and frequency of complications including Clostridium difficile infection, readmission, and all-cause mortality within 28 days of discharge., Results: Among 2225 episodes of bacteriuria, 64% were classified as ASB. After excluding patients with non-UTI indications for antibiotics, 72% of patients with ASB received antibiotics. When evaluating only patients not meeting SIRS criteria, 68% of patients with ASB received antibiotics. The mean (±SD) days of antibiotic therapy for ASB, cystitis, CA-UTI and pyelonephritis were 10.0 (4.5), 11.4 (4.7), 12.0 (6.1), and 13.6 (5.3), respectively. In sum, 14% of patients with ASB were treated for greater than 14 days, and fluoroquinolones were the most commonly used empiric antibiotic for ASB [245/691 (35%)]. Complications were rare but more common among patients with ASB treated with antibiotics., Conclusions: The majority of bacteriuria among inpatient veterans is due to ASB with high rates of treatment of ASB and prolonged durations of therapy for ASB and symptomatic UTIs., (Published by Oxford University Press for the Infectious Diseases Society of America 2017.

- Abstract
OBJECTIVE To detail the activities of the Veterans Health Administration (VHA) Antimicrobial Stewardship Initiative and evaluate outcomes of the program. DESIGN Observational analysis. SETTING The VHA is a large integrated healthcare system serving approximately 6 million individuals annually at more than 140 medical facilities. METHODS Utilization of nationally developed resources, proportional distribution of antibiotics, changes in stewardship practices and patient safety measures were reported. In addition, inpatient antimicrobial use was evaluated before and after implementation of national stewardship activities. RESULTS Nationally developed stewardship resources were well utilized, and many stewardship practices significantly increased, including development of written stewardship policies at 92% of facilities by 2015 (P<.05). While the proportional distribution of antibiotics did not change, inpatient antibiotic use significantly decreased after VHA Antimicrobial Stewardship Initiative activities began (P<.0001). A 12% decrease in antibiotic use was noted overall. The VHA has also noted significantly declining use of antimicrobials prescribed for resistant Gram-negative organisms, including carbapenems, as well as declining hospital readmission and mortality rates. Concurrently, the VHA reported decreasing rates of Clostridium difficile infection. CONCLUSIONS The VHA National Antimicrobial Stewardship Initiative includes continuing education, disease-specific guidelines, and development of example policies in addition to other highly utilized resources. While no specific ideal level of antimicrobial utilization has been established, the VHA has shown that improving antimicrobial usage in a large healthcare system may be achieved through national guidance and resources with local implementation of antimicrobial stewardship programs.

- Abstract
Objective: Practice guidelines recommend the shortest duration of antimicrobial therapy appropriate to treat uncomplicated pneumonia be prescribed to reduce the emergence of resistant pathogens. A national evaluation was conducted to assess the duration of therapy for pneumonia., Design: Retrospective medication utilization evaluation., Setting: Thirty Veterans Affairs medical centers., Patients: Inpatients discharged with a diagnosis of pneumonia., Measurements: A manual review of electronic medical records of inpatients discharged with uncomplicated community-acquired pneumonia (CAP) or healthcare-associated pneumonia (HCAP) was conducted. Appropriate CAP therapy duration was defined as at least 5 days, and up to 3 additional days beginning the first day the patient achieved clinical stability criteria; the appropriate HCAP therapy duration was defined as 8 days. The duration of antimicrobial therapy for intravenous (IV) and oral (PO) inpatient administration, PO therapy dispensed upon discharge, Clostridium difficile infection (CDI), hospital readmission, and death rates were measured., Results: Of 3881 pneumonia admissions, 1739 met inclusion criteria (CAP [n = 1195]; HCAP [n = 544]). Overall, 13.9% of patients (CAP [6.9%], HCAP [29.0%]) received therapy duration consistent with guideline recommendations. The median (interquartile range) days of therapy were 4 days (3-6 days), 1 day (0-3 days), and 6 days (4-8 days) for inpatient IV, inpatient PO, and outpatient PO antimicrobials, respectively. CDI was rare but more common in patients who received therapy duration consistent with guidelines. Therapy duration was not associated with the readmission or mortality rate., Conclusions: Antimicrobials were commonly prescribed for a longer duration than guidelines recommend. The majority of excessive therapy was completed upon discharge, identifying the need for strategies to curtail unnecessary use postdischarge.

- Abstract
Over the past decade, the Department of Veterans Affairs (VA) Pharmacy Benefits Management Services (PBM) has enhanced its formulary management activities and added programs to ensure that the national drug plan continues to meet the pharmacy needs of veterans and to promote safe and appropriate drug therapy in the face of rising medication expenditures. This article describes the broad range of services provided by the VA PBM that work in partnership to deliver a high-quality and sustainable pharmacy benefit for veterans. In support of formulary management, VA PBM pharmacists prepare extensive clinical guidance documents (e.g., drug monographs and criteria for use) that are used by physicians and pharmacists with operational and clinical oversight of the VA national formulary. The VA PBM has utilized various contracting techniques and continually evaluates drug utilization data to identify opportunities for potential savings. Remarkably, since before 2004, the average acquisition cost for a 1-month supply of medication has remained fairly stable at approximately $13-$15. Two new VA PBM programs are the VA Center for Medication Safety (VA MedSAFE) and the Clinical Pharmacy Practice Office (CPPO). VA MedSAFE is a comprehensive pharmacovigilance program focused on the detection, assessment, and prevention of adverse drug events, and CPPO is dedicated to improving safe and appropriate medication use by supporting and expanding clinical pharmacy practice. Moving forward, the VA PBM will consider new initiatives to stay at the forefront of providing quality care while maintaining economic viability., Disclosures: No outside funding supported this research. This work was supported by VA Pharmacy Benefits Management Services (VA PBM), Hines, Illinois, and VA Pittsburgh Healthcare System, Pittsburgh, Pennsylvania. Glassman is co-director of the VA Center for Medication Safety, which is part of the VA PBM. He is also part of the Medical Advisory Panel for the VA PMB. All other authors are employed by the VA PBM. The views expressed in this article are those of the authors, and no official endorsement by the U.S. Department of Veteran Affairs or the U.S. government is intended or should be inferred. Study concept and design were contributed by Valentino, Cunningham, Good, Aspinall, and Sales.

- Abstract
Background: Despite efforts to reduce antibiotic prescribing for acute respiratory infections (ARIs), information on factors that drive prescribing is limited., Objective: To examine trends in antibiotic prescribing in the Veterans Affairs population over an 8-year period and to identify patient, provider, and setting sources of variation., Design: Retrospective, cross-sectional study., Setting: All emergency departments and primary and urgent care clinics in the Veterans Affairs health system., Participants: All patient visits between 2005 and 2012 with primary diagnoses of ARIs that typically had low proportions of bacterial infection. Patients with infections or comorbid conditions that indicated antibiotic use were excluded., Measurements: Overall antibiotic prescription; macrolide prescription; and patient, provider, and setting characteristics extracted from the electronic health record., Results: The proportion of 1 million visits with ARI diagnoses that resulted in antibiotic prescriptions increased from 67.5% in 2005 to 69.2% in 2012 (P < 0.001). The proportion of macrolide antibiotics prescribed increased from 36.8% to 47.0% (P < 0.001). Antibiotic prescribing was highest for sinusitis (adjusted proportion, 86%) and bronchitis (85%) and varied little according to fever, age, setting, or comorbid conditions. Substantial variation was identified in prescribing at the provider level: The 10% of providers who prescribed the most antibiotics did so during at least 95% of their ARI visits, and the 10% who prescribed the least did so during 40% or fewer of their ARI visits., Limitation: Some clinical data that may have influenced the prescribing decision were missing., Conclusion: Veterans with ARIs commonly receive antibiotics, regardless of patient, provider, or setting characteristics. Macrolide use has increased, and substantial variation was identified in antibiotic prescribing at the provider level., Primary Funding Source: U.S. Department of Veterans Affairs, Centers for Disease Control and Prevention.

- Abstract
Objectives: To assess rates of starting or stopping antibiotics across different hospitals., Methods: We used barcode medication administration data to measure antibiotic use on acute-care wards in 128 Veterans Affairs medical centres (VAMCs) in 2010. A treatment day (TD) was defined as the administration of any antibiotic on a given day. A treatment period (TP) was defined as an interval of inpatient antimicrobial therapy with gaps of ≤1 day in TDs. The rate of starting antibiotics was calculated for inpatients who had not yet started antibiotics, as the number of start events divided by the 'person-time at risk'. The rate of stopping antibiotics was calculated analogously for inpatients that were on antibiotics. Once individuals had stopped antibiotics they were removed from further analysis. Per-day start and stop rates were also calculated for each day of hospitalization., Results: The hospital mean rate of starting the first TP was 18.1 start events/100 days at risk (range 8.4-25.6/100 days at risk). The mean hospital stopping rate was 21.1 stop events/100 days at risk (range 13.3-29.5/100 days at risk). The ratio of a facility's starting and stopping rates was highly correlated with overall antibiotic use in TDs/1000 patient-days (rs=0.92, P<0.001), while starting and stopping rates individually were only moderately correlated (rs=0.39, P<0.001)., Conclusions: VAMCs with similar antibiotic use showed marked differences in their starting and stopping rates of antibiotics. It may be useful to target empirical therapy when starting rates are high and definitive therapy when stopping rates are low., (Published by Oxford University Press on behalf of the British Society for Antimicrobial Chemotherapy 2014.

- Abstract
Importance: Inappropriate antimicrobial drug use is associated with adverse events in hospitalized patients and contributes to the emergence and spread of resistant pathogens. Targeting effective interventions to improve antimicrobial use in the acute care setting requires understanding hospital prescribing practices., Objective: To determine the prevalence of and describe the rationale for antimicrobial use in participating hospitals., Design, Setting, and Participants: One-day prevalence surveys were conducted in acute care hospitals in 10 states between May and September 2011. Patients were randomly selected from each hospital's morning census on the survey date. Data collectors reviewed medical records retrospectively to gather data on antimicrobial drugs administered to patients on the survey date and the day prior to the survey date, including reasons for administration, infection sites treated, and whether treated infections began in community or health care settings., Main Outcomes and Measures: Antimicrobial use prevalence, defined as the number of patients receiving antimicrobial drugs at the time of the survey divided by the total number of surveyed patients., Results: Of 11,282 patients in 183 hospitals, 5635 (49.9%; 95% CI, 49.0%-50.9%) were administered at least 1 antimicrobial drug; 77.5% (95% CI, 76.6%-78.3%) of antimicrobial drugs were used to treat infections, most commonly involving the lower respiratory tract, urinary tract, or skin and soft tissues, whereas 12.2% (95% CI, 11.5%-12.8%) were given for surgical and 5.9% (95% CI, 5.5%-6.4%) for medical prophylaxis. Of 7641 drugs to treat infections, the most common were parenteral vancomycin (1103, 14.4%; 95% CI, 13.7%-15.2%), ceftriaxone (825, 10.8%; 95% CI, 10.1%-11.5%), piperacillin-tazobactam (788, 10.3%; 95% CI, 9.6%-11.0%), and levofloxacin (694, 9.1%; 95% CI, 8.5%-9.7%). Most drugs administered to treat infections were given for community-onset infections (69.0%; 95% CI, 68.0%-70.1%) and to patients outside critical care units (81.6%; 95% CI, 80.4%-82.7%). The 4 most common treatment antimicrobial drugs overall were also the most common drugs used for both community-onset and health care facility-onset infections and for infections in patients in critical care and noncritical care locations., Conclusions and Relevance: In this cross-sectional evaluation of antimicrobial use in US hospitals, use of broad-spectrum antimicrobial drugs such as piperacillin-tazobactam and drugs such as vancomycin for resistant pathogens was common, including for treatment of community-onset infections and among patients outside critical care units. Further work is needed to understand the settings and indications for which reducing antimicrobial use can be most effectively and safely accomplished.

- Abstract
Background: The introduction of the first direct-acting antiviral agents (DAAs) for the treatment of hepatitis C virus (HCV), telaprevir and boceprevir, marked a unique event in which 2 disease-changing therapies received FDA approval at the same time. Comparative safety and effectiveness data in real-world populations upon which to make formulary decisions did not exist., Objective: To describe the implementation, measurement, and outcomes of an enduring population-based approach of surveillance of medication management for HCV., Methods: The foundation of the population approach to HCV medication management used by the Department of Veterans Affairs (VA) relied upon a basic framework of (a) providing data for effective regional and local management, (b) education and training, (c) real-time oversight and feedback from a higher organization level, and (d) prompt outcome sharing. These population-based processes spanned across the continuum of the direct-acting antiviral oversight process. We used the VA's HCV Clinical Case Registry-which includes pharmacy, laboratory, and diagnosis information for all HCV-infected veterans from all VA facilities-to assess DAA treatment eligibility, DAA uptake and timing, appropriate use of DAAs including HCV RNA monitoring and medication possession ratios (MPR), nonconcordance with guidance for adjunct erythropoiesis-stimulating agent (ESA) and granulocyte colony-stimulating factor (GCSF) use, hematologic adverse effects, discontinuation rates, and early and sustained virologic responses. Training impact was assessed via survey and change in pharmacist scope of practice., Results: One year after FDA approval, DAAs had been prescribed at 120 of 130 VA facilities. Over 680 VA providers participated in live educational training programs including 380 pharmacists, and pharmacists with a scope of practice for HCV increased from 59 to 110 pharmacists (86%). HCV RNA futility testing improved such that only 1%-3% of veterans did not have appropriate testing compared with 15%-17% 6 months earlier. By facility, the median proportion of veterans with MPR ≥ 0.95 remained 80% for those prescribed boceprevir; for telaprevir, the median proportion was 75% and improved to 80% 6 months later. Nonconcordance with VA medication guidance was as follows: receipt of an ESA without dose reducing ribavirin, 30% boceprevir, 45% telaprevir; ESA initiated with a hemoglobin greater than 10 g/dL, 42% boceprevir, 25% telaprevir; receipt of GCSF with absolute neutrophil count above the criteria threshold, 84%., Conclusions: This clinically focused, comprehensive, population-based medication management approach affected real-time change in health services, practice, and outcomes evidenced by widespread and rapid DAA uptake, improved HCV RNA monitoring, attention to adherence, and more appropriate management of DAA-related anemia. Timely outcome sharing provided decision makers and clinicians evidence to support current HCV practices.

- Abstract
Objective: To estimate avoidable intravenous (IV) fluoroquinolone use in Veterans Affairs (VA) hospitals., Design: A retrospective analysis of bar code medication administration (BCMA) data., Setting: Acute care wards of 128 VA hospitals throughout the United States., Methods: Data were analyzed for all medications administered on acute care wards between January 1, 2006, and December 31, 2010. Patient-days receiving therapy were expressed as fluoroquinolone-days (FD) and divided into intravenous (IV; all doses administered intravenously) and oral (PO; at least one dose administered per os) FD. We assumed IV fluoroquinolone use to be potentially avoidable on a given IV FD when there was at least 1 other medication administered via the enteral route., Results: Over the entire study period, 884,740 IV and 830,572 PO FD were administered. Overall, avoidable IV fluoroquinolone use accounted for 46.8% of all FD and 90.9% of IV FD. Excluding the first 2 days of all IV fluoroquinolone courses and limiting the analysis to the non-ICU setting yielded more conservative estimates of avoidable IV use: 20.9% of all FD and 45.9% of IV FD. Avoidable IV use was more common for levofloxacin and more frequent in the ICU setting. There was a moderate correlation between avoidable IV FD and total systemic antibiotic use (r = 0.32)., Conclusions: Unnecessary IV fluoroquinolone use seems to be common in the VA system, but important variations exist between facilities. Antibiotic stewardship programs could focus on this patient safety issue as a "low-hanging fruit" to increase awareness of appropriate antibiotic use.

- Abstract
Multidrug-resistant (MDR) and carbapenem-resistant (CR) Gram-negative pathogens are becoming increasingly prevalent around the globe. Polymyxins and tigecycline are among the few antibiotics available to treat infections with these bacteria but little is known about the frequency of their use. We therefore aimed to estimate the parenteral use of these two drugs in Veterans Affairs medical centers (VAMCs) and to describe the pathogens associated with their administration. For this purpose we retrospectively analyzed barcode medication administration data of parenteral administrations of polymyxins and tigecycline in 127 acute-care VAMCs between October 2005 and September 2010. Overall, polymyxin and tigecycline use were relatively low at 0.8 days of therapy (DOT)/1000 patient days (PD) and 1.6 DOT/1000PD, respectively. Use varied widely across facilities, but increased overall during the study period. Eight facilities accounted for three-quarters of all polymyxin use. The same statistic for tigecycline use was twenty-six VAMCs. There were 1,081 MDR or CR isolates during 747 hospitalizations associated with polymyxin use (1.4/hospitalization). For tigecycline these number were slightly lower: 671 MDR or CR isolates during 500 hospitalizations (1.3/hospitalization) (p = 0.06). An ecological correlation between the two antibiotics and combined CR and MDR Gram-negative isolates per 1000PD during the study period was also observed (Pearson's correlation coefficient r = 0.55 polymyxin, r = 0.19 tigecycline). In summary, while polymyxin and tigecycline use is low in most VAMCs, there has been an increase over the study period. Polymyxin use in particular is associated with the presence of MDR Gram-negative pathogens and may be useful as a surveillance measure in the future.

- Abstract
Aerosolized delivery of antimicrobial agents is an attractive option for management of pulmonary infections, as this is an ideal method of providing high local drug concentrations while minimizing systemic exposure. With the paucity of consensus regarding the safety, efficacy, and means with which to use aerosolized antimicrobials, a task force was created by the Society of Infectious Diseases Pharmacists to critically review and evaluate the literature on the use of aerosolized antiinfective agents. This article summarizes key findings and statements for preventing or treating a variety of infectious diseases, including cystic fibrosis, bronchiecstasis, hospital-acquired pneumonia, fungal infections, nontuberculosis mycobacterial infection, and Pneumocystis jiroveci pneumonia. Our intention was to provide guidance for clinicians on the use of aerosolized antibiotics through evidence-based pharmacotherapy. Further research with well-designed clinical trials is necessary to elucidate the optimal dosage and duration of therapy and, of equal importance, to appreciate the true risks associated with the use of aerosolized delivery systems.

- Abstract
In the USA, >50% of candidemia episodes occur in medical or surgical intensive care units (SICU). However, studies focused on patterns and rationale for antifungal use are lacking. The objective of this study was to evaluate systemic antifungal usage in SICU patients. Retrospective audit of SICU patients receiving antifungal therapy from four American hospitals. Medical records were reviewed for demographics, hospital variables, microbiology results, antifungal regimens and indications for therapy. A total of 2411 patient-days of antifungal use were evaluated in 225 patients. Fluconazole was the most frequently prescribed antifungal (1846 patient-days) followed by amphotericin B deoxycholate (251 patient-days), lipid formulations of amphotericin B (201 patient-days), itraconazole (71 patient-days), and caspofungin (42 patient-days). Antifungals were prescribed empirically (44%), for preemptive therapy in critically ill patients colonised with Candida (43%), or for candidiasis (12%). Candida species were recovered from 98% of patients with positive fungal cultures most commonly from pulmonary (53%) or urinary sources (17%). Fluconazole is the most frequently prescribed antifungal agent in SICUs and is most often prescribed for empiric or preemptive indications. Research efforts to identify patients who warrant preemptive antifungal therapy for invasive candidiasis could dramatically change antifungal prescribing patterns in the SICU.

Background: It is likely that a large amount of unused and outdated medications exists in households throughout the US; however, the amount and potential costs of these medications are unknown., Objective: To determine the amount, types, and costs of unused medications present in a neighborhood surrounding a community pharmacy in Houston, Texas., Methods: A community trial was conducted between April and September 2002. This pilot study investigated the quantity and types of drugs returned to a community pharmacy over a 6-month period., Results: During the study period, approximately 17000 oral pills worth over US dollars 26000 were collected in 1315 medication containers. Medications collected were from all drug classes and types (pharmaceutical samples, over-the-counter and prescription drugs)., Conclusions: This study demonstrated that an enormous amount of unused medications were present in a community in the US. Community pharmacies may be an ideal venue to collect and destroy these unused drugs.
