Controlling costs and improving quality outcomes are important considerations of the triple aim in health care. Medication adherence to oral antidiabetic (OAD) medications is an outcome measure for those with diabetes. However, there is little research reporting the costs associated with OAD medication adherence among adults with diabetes and comorbid infections.To provide nationally representative cost and utilization estimates from a payer perspective of 2 common comorbid infections: urinary tract infection (UTI) and skin and soft tissue infection (SSTI) among adults with diabetes in relation to OAD medication nonadherence to quantify cost per outcome.A retrospective observational study for years 2010-2015 used longitudinal panel data in the public domain from the Medical Expenditure Panel Survey (MEPS). The study included individuals aged ≥ 18 years with diabetes (excluding gestational diabetes) who were prescribed OAD medications and then stratified by infection status, that is, without infection versus with UTI and/or SSTI. Outcomes measured included medication adherence, defined as medication possession ratio (MPR); treated prevalence of UTI and SSTI; and associated direct medical costs paid by insurers.4,633 adults with diabetes were included; of those, 12% reported a UTI or SSTI, with the weighted sample representing 2.2 million U.S. residents. The mean MPR was 0.61 and 0.63 in the infection and noninfection groups, respectively. Less than 35% in each group were adherent to OAD medications. Having a UTI or SSTI increased the adjusted total health expenses by 53.7% (In adults with diabetes, a UTI or SSTI diagnosis did not influence medication adherence to OAD medication but increased health care utilization and costs significantly.This study was supported by the Virginia Commonwealth University Presidential Research Quest Fund (PeRQ Fund).

Background Gram-negative organisms (GNOs) have increasing resistance rates to levofloxacin at Virginia Commonwealth University Health System (VCUHS), where levofloxacin is the most common agent added to provide double coverage of gram-negative infections. The goal of this study was to determine the adequacy of empiric gram-negative coverage for septic patients at our institution. Methods A retrospective review of patients admitted to VCUHS, from January 1, 2014, to December 31, 2014, with a diagnosis of sepsis, severe sepsis, or septic shock and documented infection, was performed to determine the adequacy of various empiric antibiotic combinations. Results Of 219 patients who met the inclusion criteria, 56% of patients received monotherapy and 21% of patients received combination therapy (2 antibiotics) covering GNOs. GNOs (84%) were susceptible to piperacillin-tazobactam. When used in combination with cefepime and meropenem, levofloxacin did not increase coverage. However, levofloxacin provided an 8% increase in coverage and gentamicin provided an additional 13% increase in coverage, respectively, when used in combination with piperacillin-tazobactam. Conclusions Among septic patients at VCUHS, gentamicin provided increased gram-negative coverage when compared with levofloxacin. Although susceptibility to piperacillin-tazobactam alone was relatively low, the combination of piperacillin-tazobactam and gentamicin provided nearly equivalent coverage to meropenem and gentamicin.

Clostridioides difficile infection guidelines were published in final format on April 1, 2018. Among 4962 and 3545 C. difficile infection cases in children the year before and after publication, oral metronidazole use decreased from 63.0% to 44.3% (P < 0.001) and oral vancomycin use increased from 27.3% to 47.7% (P < 0.001). Quarterly metronidazole utilization decreased postguidelines among 117 institutions, incidence rate ratios 0.86 (95% confidence intervals: 0.78-0.96).

Background Identification of factors associated with antifungal utilization in neonatal, pediatric, and adult patient groups is needed to guide antifungal stewardship initiatives in academic medical centers. Methods For this hospital-level analysis, we analyzed antifungal use in hospitals across the United States of America, excluding centers only providing care for hematology/oncology patients. Analysis of variance was used to compare antifungal use between patient groups. Three multivariable linear regression models were used to determine independent factors associated with antifungal use in the neonatal, pediatric, and adult patient groups. Results For the neonatal, pediatric, and adult patient groups, 54, 44, and 60 hospitals were included, respectively. Total antifungal use was significantly lower in the neonatal patient group (14 days of therapy (DOT)/1000 patient days (PDs) versus 76 in pediatrics and 74 in adults, p

Objective. To compare educational outcomes between two iterations of a scholarship and research course for Doctor of Pharmacy (PharmD) students at Virginia Commonwealth University’s School of Pharmacy. Methods. The first iteration of a course intended to teach pharmacy students the knowledge and skills necessary to design and conduct research involved lectures and application exercises, including limited guided questions about different aspects of the research process. In the fall of 2015, multiple structured activities and accompanying grading rubrics, each designed around the structure and content of a section of a research proposal, were introduced to the course to supplement lectures. Both iterations of the course culminated with students submitting a research proposal. After establishing interrater reliability, faculty members graded a random sample of 20 research proposals, 10 from each version of the course, and section-specific and overall proposal scores were compared. Results. In the proposals submitted after the course revisions, significant improvements in three areas were identified: the overall score, the section-specific scores for research hypothesis/specific aims, and institutional review board (IRB) discussion/informed consent. Nominal, though not statistically significant, improvements were observed in other sections. Conclusion. Additional research is needed regarding the best instructional strategies to reinforce data analysis and statistical testing knowledge and skills in PharmD students. Overall, our findings support the hypothesis that a more formalized, guided approach for teaching research methods improves learning outcomes for PharmD students.

Background The Centers for Medicare and Medicaid Services (CMS) implemented a core measure sepsis (SEP-1) bundle in 2015. One element was initiation of broad-spectrum antibiotics within 3 hours of diagnosis. The policy has the potential to increase antibiotic use and Clostridioides difficile infection (CDI). We evaluated the impact of SEP-1 implementation on broad-spectrum antibiotic use and CDI occurrence rates. Methods Monthly adult antibiotic data for 4 antibiotic categories (surgical prophylaxis, broad-spectrum for community-acquired infections, broad-spectrum for hospital-onset/multidrug-resistant [MDR] organisms, and anti–methicillin-resistant Staphylococcus aureus [MRSA]) from 111 hospitals participating in the Clinical Data Base Resource Manager were evaluated in periods before (October 2014–September 2015) and after (October 2015–June 2017) policy implementation. Interrupted time series analyses, using negative binomial regression, evaluated changes in antibiotic category use and CDI rates. Results At the hospital level, there was an immediate increase in the level of broad-spectrum agents for hospital-onset/MDR organisms (+2.3%, P = .0375) as well as a long-term increase in trend (+0.4% per month, P = .0273). There was also an immediate increase in level of overall antibiotic use (+1.4%, P = .0293). CDI rates unexpectedly decreased at the time of SEP-1 implementation. When analyses were limited to patients with sepsis, there was a significant level increase in use of all antibiotic categories at the time of SEP-1 implementation. Conclusions SEP-1 implementation was associated with immediate and long-term increases in broad-spectrum hospital-onset/MDR organism antibiotics. Antimicrobial stewardship programs should evaluate sepsis treatment for opportunities to de-escalate broad therapy as indicated.

The recently described proportion of carbapenem consumption metric was used to assess the effectiveness of formulary restriction for carbapenems for 2 units housing predominantly immunocompromised patients at a large academic medical center. Interrupted time series analysis revealed a significant decrease in meropenem use for hematology-oncology and bone marrow transplant units after restriction.

Patients with cancer are vulnerable to Clostridium difficile infection (CDI); hospitals with larger oncology populations may have worse CDI performance. Among 71 academic hospitals studied, there were significant differences in oncology patient-days per 1,000 admissions across CDI standardized infection ratio categories of better, no different, and worse; worse hospitals had the greatest number of patient-days. Oncology patients' most commonly used high-risk CDI medications were quinolones, third- and fourth-generation cephalosporins, and proton pump inhibitors.

OBJECTIVES To assess student pharmacist best activity scores and related exam question performance based on the number of pediatric virtual patient activity (VPA) attempts. METHODS A 40-point asthma VPA was implemented and included three possible randomized scenarios. A 60-point meningitis VPA was implemented and included three possible randomized scenarios followed by an additional three possible randomized scenarios only if the first scenario was correctly completed. Points were awarded in the VPA based on appropriateness of treatment decisions. Students were allowed unlimited VPA attempts individually and as a group in class. Three exam questions were based on a fourth scenario of each randomized portion of the VPAs. The Kruskal-Wallis test, Mann-Whitney U test, and T-test were used for statistical comparisons when appropriate. RESULTS Of 132 students, median individual best asthma VPA scores were 15.25, 22, and 30 for those with 1, 2, and ≥3 asthma attempts, respectively (p < 0.001). Median individual best meningitis VPA scores were 4, 5, 7, and 45.5 for those with 1, 2, 3 to 4, and ≥5 attempts, respectively (p < 0.001). Median number of group VPA attempts was higher among students who correctly answered the exam question related to the first randomized meningitis scenario (10 versus 4, p = 0.015), although no differences in attempts were found for the other related questions (all p > 0.05). CONCLUSIONS Students who completed the VPAs more times achieved greater individual best scores. Students who correctly answered related exam questions had a higher number of group VPA attempts only when continuation of the VPA required correct randomized scenario completion.

OBJECTIVE Healthcare-associated infections (HAIs) pose a challenge to patient safety. Although studies have explored individual level, few have focused on organizational factors such as a hospital's safety infrastructure (indicated by Leapfrog Hospital Safety Score) or workplace quality (Magnet recognition). The aim of the study was to determine whether Magnet and hospitals with better Leapfrog Hospital Safety Scores have fewer HAIs. METHODS Ordered probit regression analyses tested associations between Safety Score, Magnet status, and standardized infection ratios, depicting whether a hospital had a Clostridium difficile infection (CDI) and methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection standardized infection ratio that was "better," "no different," or "worse" than a National Benchmark as per Centers for Disease Control and Prevention's National Healthcare Safety Network definitions. RESULTS Accounting for confounders, relative to "A" hospitals, "B" and "C" hospitals had significant and negative relationships with CDI (-0.16, P < 0.01, and -0.14, P < 0.05, respectively) but not MRSA bacteremia. Magnet hospitals had a significant and positive relationship with MRSA bloodstream infections (0.74, P < 0.001) but a significant negative relationship with CDI (-0.21, P < 0.01) compared with non-Magnet. CONCLUSIONS A hospitals performed better on CDI but not MRSA bloodstream infections. In contrast, Magnet designation was associated with fewer than expected MRSA infections but more than expected CDIs. These mixed results indicate that hospital global assessments of safety and workplace quality differentially and imperfectly predict its level of HAIs, suggesting the need for more precise organizational measures of safety and more nuanced approaches to infection prevention and reduction.

Mobile medical apps are commonly used by health care professionals and could be used by antimicrobial stewardship programs to enhance adherence to local recommendations. We conducted a survey of health care workers to inform the design of an antimicrobial stewardship smartphone app.

Hospital antibiograms are a method for presenting cumulative antibiotic susceptibility data using routinely collected clinical microbiology data. They provide critical foundational knowledge to inform development of antimicrobial stewardship program (ASP) strategies but are also provided to clinicians to inform empiric antibiotic therapy selection. Earlier research has demonstrated that use of the antibiogram to direct prudent antibiotic selection is less than desired. Use by non-infectious disease practitioners has been limited, and antibiotic prescribing has not aligned with ASP goals. Over the past 5 years, newer research has emerged to increase the utility of the antibiogram through education, stratification, and cross-tabulation of data for combination therapy. These approaches focus on increasing use of the cumulative antibiogram and ensuring that the data appropriately influence the antibiotic therapy selection. Data available to date suggest that these strategies can be effective methods of increasing use of concordant and relatively narrow spectrum empiric antibiotic regimens.

Purpose This study compares antimicrobial stewardship program (ASP)–stated goals and outcomes collected as well as opinions regarding national metric establishment. Methods Twenty-one ASP members underwent telephone interviews answering open-ended questions about ASP goals, outcomes collected, and opinions about national metrics. Content analysis was used to code responses into predefined ASP-metric categories. Findings The most common ASP goal was antimicrobial appropriateness (76%), outcomes tracked were use and microbial outcomes (both 71%), and desired national metric was use (67%). Implications Stated-goals, outcomes tracked, and opinions regarding national metric establishment did not fully align. With ASP-related regulations looming, it is important that alignment is increased.

Background Although effectiveness of fecal microbiota transplantation (FMT) has been adequately documented, the patient experience of undergoing FMT has not. Methods We carried out a qualitative interview study using semistructured questions relating to aspects of health pre-FMT, during FMT, and post-FMT periods with 17 participants. Inductive coding was used to identify core themes during the periods. Results Pre-FMT themes included physical (continuous diarrhea and weight loss), mental (depression, wanting to die, and fear), quality of life (unable to perform normal activities), social support, and financial (medication costs) factors. Provider resistance/limited awareness were barriers to FMT. Participants reached a tipping point, experiencing feelings of hopelessness, which led them to pursue FMT. During FMT, participants commented on lack of a so-called ick factor. During the posttreatment period, participants experienced symptom relief, but had residual fears. Patient activation was present during all phases, including information seeking and empowerment. Conclusions During the pre-FMT period, participants experienced extreme discomfort and encountered FMT barriers. Undergoing FMT was reported as easy but residual fear remained. There were displays of patient activation at all FMT time periods, including the seeking of FMT. Participants could have benefited from having undergone FMT sooner, demonstrating a need for improvement in provider education and health system barriers regarding FMT.

Antimicrobial resistance was declared a serious threat to global public health by the World Health Organization. Actions have been taken to improve antimicrobial use, especially in settings such as hospitals. However, a large amount of antimicrobials are administered to food-producing animals, posing a risk of spread of antibiotic-resistant organisms to humans through contaminated retail meat, or by direct contact with animals. In the USA, efforts are in place to limit the use of antimicrobials for growth enhancement as opposed to disease prevention or treatment purposes. Additionally, the US Administration is calling for improved surveillance capabilities for the monitoring of antimicrobial use in livestock and for the tracking of antimicrobial resistance through the National Antimicrobial Resistance Monitoring System, as well as for development of antimicrobial alternatives for use in food production. The restaurant industry and meat suppliers are also committing to decreasing the amounts of antimicrobials used in animal food production.

We aim to systematically review the literature on the effectiveness of pediatric antimicrobial stewardship programs (ASPs) and antimicrobial stewardship (AS) strategies in the United States (US) inpatient setting. Furthermore, we review current gaps and challenges for unique pediatric populations and those in ambulatory settings. Misuse and overuse of antimicrobials have been identified as key factors for antimicrobial resistance (AR). Multiple professional organizations support the implementation of hospital-based ASPs to decrease antimicrobial consumption, improve patient outcomes, and reduce healthcare costs. There is limited data on the effectiveness of inpatient pediatric ASPs and AS strategies in unique populations. Furthermore, there is a paucity of evidence on ASPs in ambulatory settings. This review contributes to the growing body of evidence that supports the use of pediatric ASPs to optimize antimicrobial therapy in the inpatient setting as well as in unique patient populations and ambulatory settings. Active stewardship is critical and antimicrobial consumption is a key outcome metric for programs.

To examine the prevalence and characteristics of pediatric opioid exposures and poisonings in the US.This was a retrospective, cross-sectional analysis using the National Poison Data System from January 1, 2010 to December 31, 2014. Records of children aged18 years with exposure to opioid-containing medications were identified. Standardized prevalence rates were calculated, and the annual trend was examined. Pediatric opioid exposures were characterized descriptively, and logistic regression was performed to estimate the association between various clinical and sociodemographic characteristics and exposures with serious (ie, moderate, major, or death) outcomes. The association of pediatric opioid exposures and area-level socioeconomic status factors at 5-digit ZIP code level was examined descriptively.The prevalence of opioid exposures was 22.6 per 100 000 children and was particularly high among ≤5-year-olds. Prevalence declined from 25.5 to 20 per 100 000 children from 2010 to 2014. There were 83 418 pediatric opioid exposures over the 5-year period and nearly one-half resulted in poisoning. Over 60% of exposures were among children ≤5 years of age, 73.4% were unintentional, and over 90% occurred at home. One in every 2 pediatric opioid exposures was evaluated in a healthcare facility. Annually 4912 children aged ≤5 years were treated in the emergency department or admitted for care. Older age, nonaccidental intent, and single-substance opioid, especially buprenorphine and methadone, were associated with serious outcomes (P .05). Positive correlations were observed for area-level socioeconomic status factors including proportion of adults and pediatric opioid exposures.Pediatric opioid exposures and poisonings decreased from 2010 to 2014 but morbidity remains high. The epidemiology of opioid exposures differed considerably by age.

A metric was developed to identify hospital proportion of carbapenem consumption (PoCC) among antipseudomonal antibiotics. The PoCC varied significantly among academic medical centers by Census Bureau geographic division after adjusting for patient mix. This metric may be useful in identifying disproportionate carbapenem use and potential carbapenem overuse.Infect Control Hosp Epidemiol 2018;39:229–232

Vancomycin-resistant Enterococci (VRE) infections are problematic due to limited availability of anti-VRE agents and their potential for adverse effects and drug interactions. This review focuses on the role of daptomycin in treating VRE infections by summarizing key points of relevant clinical studies. Higher doses of daptomycin (≥ 6 mg/kg), as compared to standard doses, were found to be safe in terms of creatinine phosphokinase elevation and associated with successful infection outcomes and microbiological clearance. High doses are especially important in treatment of infections involving elevated daptomycin minimum inhibitory concentration (MIC) values (3–4 μg/mL). Daptomycin, especially in higher doses, has been shown to be an effective and safe VRE agent for a variety of serious infection types, such as catheter-associated bloodstream and intra-abdominal infections, and for different populations including oncology. Infections involving higher daptomycin MIC values were associated with previous daptomycin use and prosthetic devices.

This report examines the effectiveness of antimicrobial restriction at 1 tertiary care health care system by analyzing the consumption of restricted versus nonrestricted gram-positive agents over time for medical versus surgical units. Significant reductions in restricted antibiotic use were detected in 57% of medical units versus none of the surgical units. There were no significant reductions in nonrestricted antibiotic use. We think looking at antibiotic consumption by service line provides opportunities for targeted antibiotic restriction program refinement.

OBJECTIVENational hospital performance measures for C. difficile infection (CD) are available; comparing antibacterial use among performance levels can aid in identifying effective antimicrobial stewardship strategies to reduce CDI rates.DESIGNHospital-level, cross-sectional analysis.METHODSHospital characteristics (ie, demographics, medications, patient mix) were obtained for 77 hospitals for 2013. Hospitals were assigned 1 of 3 levels of a CDI standardized infection ratio (SIR): ‘Worse than,’ ‘Better than,’ or ‘No different than’ a national benchmark. Analyses compared medication use (total and broad-spectrum antibacterials) for 3 metrics: days of therapy per 1,000 patient days; length of therapy; and proportion of patients receiving a medication across SIR levels. A multivariate, ordered-probit regression identified characteristics associated with SIR categories.RESULTSRegarding total average antimicrobial use per patient, there was a significant difference detected in mean length of therapy: ‘No different’ hospitals having the longest (4.93 days) versus ‘Worse’ (4.78 days) and ‘Better’ (4.43 days) (PPPPCONCLUSIONSThese findings have potential implications regarding the need to fully account for hospital patient mix when carrying out inter-hospital comparisons of CDI rates.Infect Control Hosp Epidemiol 2016;37:909–915

Hospitals are categorized as better, no different, or worse at a national level based on their Clostridium difficile infection performance. Institutional antimicrobial stewardship programs seek to decrease the occurrence of C difficile by implementing strategies to address antibiotic usage; however, optimal structure and strategies for accomplishing this remain largely unknown. We found that a higher proportion of hospitals with either a worse or no different rank used a postprescription audit and feedback strategy than hospitals with a better rank.

Background Facilities enrolled in the National Healthcare Safety Network (NHSN) provide annual information on their antibiotic stewardship programs (ASPs) via a mandatory survey. The survey contains 12 questions that explore uptake of CDC’s Core Elements for Hospital ASPs. Respondents (typically Infection Preventionists) are advised to seek input from pharmacist and physician ASP champions, but the professional completing the survey and the extent of input provided by ASP program personnel are unknown. A separate survey provided an opportunity to assess ASP responses reported to NHSN. Methods Individuals from 446 academic and community hospitals participating in the Vizient list-serve were surveyed in March 2016. The Vizient survey included the 12 ASP questions in the 2015 NHSN survey. Vizient responses were compared with NHSN survey responses to assess differences in reported uptake of core elements based on the professional completing the survey. Results 189 of the 211 hospitals completing the Vizient survey were successfully matched to NHSN hospitals. The majority of respondents were pharmacists; 83% were either Directors of Pharmacy or clinical pharmacists of which 48% and 61% reported assisting with the NHSN survey, respectively. Reported implementation of all 7 elements in this subset of 189 hospitals was 58.2% in the Vizient survey compared with 54.5% in NHSN. Results differed by respondent position and core element surveyed. Clinical pharmacists in the Vizient survey reported higher rates of core element adherence than Directors of Pharmacy (Figure 1). The position of survey respondents varied by hospital size. Of hospitals with less than 250 beds, 87.5% of surveys were completed by Directors of Pharmacy, whereas 77.1% of surveys were completed by clinical pharmacists in hospitals with ≥250 beds. Conclusion Overall similarities between NHSN and Vizient survey results indicate that ASP questions based on CDC’s Core Elements are interpreted in similar ways and answered consistently when analyzed overall. However, individual core element responses may differ based on position of respondent, ASP familiarity, ASP infrastructure, and/or hospital bed size. CDC is exploring improved wording of the survey questions to help further improve consistency in responses. Disclosures All authors: No reported disclosures.
