The rate at which the coronavirus disease (COVID-19) spread required a rapid response across many, if not all, industries. Academic medical centers had to rapidly evaluate, prioritize, and coordinate the multiple requests for clinical trial participation. This involved redirecting resources and developing a collaborative system for assessment, decision making, and implementation. Our institution formed a team with diverse representation from multiple stakeholders to review and prioritize all research protocols related to COVID-19. To accomplish this, a prioritization matrix was developed to help determine the order in which the protocols should be placed for consideration by the treating clinician. The purpose of the team was to review the COVID-19 clinical trials in the pipeline, prioritize those trials that best met the needs of our patients, oversee training and resource needs, and lead the formulation of procedures for integration with clinical care. Resources from the Clinical Research Unit were then allocated to support the swift execution of such studies. This manuscript describes that process, the challenges encountered, and the lessons learned on how to make all clinical trials more successful in a complex and dynamic environment.

Challenges for infection prevention and antimicrobial stewardship programs have arisen with the fourth wave of the coronavirus disease 2019 (COVID-19) pandemic, fueled by the delta variant. These challenges include breakthrough infections in vaccinated individuals, decisions to re-escalate infection prevention measures, critical medication shortages, and provider burnout. Various strategies are needed to meet these challenges.

Background: Data regarding outpatient antibiotic prescribing for urinary tract infections (UTIs) are limited, and they have never been formally summarized in Virginia. Objective: We describe outpatient antibiotic prescribing trends for UTIs based on gender, age, geographic region, insurance payer and International Classification of Disease, Tenth Revision (ICD-10) codes in Virginia. Methods: We used the Virginia All-Payer Claims Database (APCD), administered by Virginia Health Information (VHI), which holds data for Medicare, Medicaid, and private insurance. The study cohort included Virginia residents who had a primary diagnosis of UTI, had an antibiotic claim 0–3 days after the date of the diagnosis and who were seen in an outpatient facility in Virginia between January 1, 2016, and December 31, 2016. A diagnosis of UTI was categorized as cystitis, urethritis or pyelonephritis and was defined using the following ICD-10 codes: N30.0, N30.00, N30.01, N30.9, N30.90, N30.91, N39.0, N34.1, N34.2, and N10. The following antibiotics were prescribed: aminoglycosides, sulfamethoxazole/trimethoprim (TMP-SMX), cephalosporins, fluoroquinolones, macrolides, penicillins, tetracyclines, or nitrofurantoin. Patients were categorized based on gender, age, location, insurance payer and UTI type. We used χ2 and Cochran-Mantel-Haenszel testing. Analyses were performed in SAS version 9.4 software (SAS Institute, Cary, NC). Results: In total, 15,580 patients were included in this study. Prescriptions for antibiotics by drug class differed significantly by gender (P < .0001), age (P < .0001), geographic region (P < .0001), insurance payer (P < .0001), and UTI type (P < .0001). Cephalosporins were prescribed more often to women (32.48%, 4,173 of 12,846) than to men (26.26%, 718 of 2,734), and fluoroquinolones were prescribed more often to men (53.88%, 1,473 of 2,734) than to women (47.91%, 6,155 of 12,846). Although cephalosporins were prescribed most frequently (42.58%, 557 of 1,308) in northern Virginia, fluoroquinolones were prescribed the most in eastern Virginia (50.76%, 1677 of 3,304). Patients with commercial health insurance, Medicaid, and Medicare were prescribed fluoroquinolones (39.31%, 1,149 of 2,923), cephalosporins (56.33%, 1,326 of 2,354), and fluoroquinolones (57.36%, 5,910 of 10,303) most frequently, respectively. Conclusions: Antibiotic prescribing trends for UTIs varied by gender, age, geographic region, payer status and UTI type in the state of Virginia. These data will inform future statewide antimicrobial stewardship efforts. Funding: None Disclosures: Michelle Doll reports a research grant from Molnlycke Healthcare.

The use of an electronic hand hygiene monitoring system (EHHMS) decreased due to the coronavirus disease 2019 (COVID-19) pandemic. We analyzed dispenser use, hand hygiene (HH) badge use, and HH compliance to determine the effect of COVID-19 on EHHMS use and HH compliance. HH product shortages and other pandemic-induced challenges influenced EHHMS use.

We describe traditional antimicrobial stewardship program (ASP) activities with a discussion of how these activities can be refocused in the setting of the COVID-19 pandemic. Additionally, we discuss possible adverse consequences of ASP attention diversion on COVID-19 response efforts and overall implications for future pandemic planning. We also discuss ASP in collaboration with other groups within health systems and how COVID-19 may affect these relationships long term. Despite the paucity of literature on Antimicrobial Stewardship and COVID-19, the potential contributions of ASPs during a pandemic are numerous. ASPs can develop strategies to identify patients with COVID-19-like-illness; this is particularly useful when these patients are missed at the time of health system entry. ASPs can also play a critical role in the management of potential drug shortages, developing local treatment guidelines, optimizing the use of antibiotics, and in the diagnostic stewardship of COVID-19 testing, among other roles. Importantly, it is often difficult to ascertain whether critically ill patients who are hospitalized with COVID-19 have concurrent or secondary bacterial infections-ASPs are ideally situated to help optimize antimicrobial use for these patients via a variety of mechanisms. ASPs are uniquely positioned to aid in pandemic response planning and relief efforts. ASPs are already integrated into health systems and play a key role in optimizing antimicrobial prescribing. As ASPs assist in COVID-19 response, understanding the role of ASPs in pandemic relief efforts may mitigate damage from future outbreaks.

To assess the impact of major interventions targeting infection control and diagnostic stewardship in efforts to decrease Clostridioides difficile hospital onset rates over a 6-year period.Interrupted time series.The study was conducted in an 865-bed academic medical center.Monthly hospital-onset C. difficile infection (HO-CDI) rates from January 2013 through January 2019 were analyzed around 5 major interventions: (1) a 2-step cleaning process in which an initial quaternary ammonium product was followed with 10% bleach for daily and terminal cleaning of rooms of patients who have tested positive for C. difficile (February 2014), (2) UV-C device for all terminal cleaning of rooms of C. difficile patients (August 2015), (3) "contact plus" isolation precautions (June 2016), (4) sporicidal peroxyacetic acid and hydrogen peroxide cleaning in all patient areas (June 2017), (5) electronic medical record (EMR) decision support tool to facilitate appropriate C. difficile test ordering (March 2018).Environmental cleaning interventions and enhanced "contact plus" isolation did not impact HO-CDI rates. Diagnostic stewardship via EMR decision support decreased the HO-CDI rate by 6.7 per 10,000 patient days (P = .0079). When adjusting rates for test volume, the EMR decision support significance was reduced to a difference of 5.1 case reductions per 10,000 patient days (P = .0470).Multiple aggressively implemented infection control interventions targeting CDI demonstrated a disappointing impact on endemic CDI rates over 6 years. This study adds to existing data that outside of an outbreak situation, traditional infection control guidance for CDI prevention has little impact on endemic rates.

Background Contact precautions (CP) are a widely adopted strategy to prevent cross-transmission of organisms, commonly methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). Some hospitals have discontinued CP for patients with MRSA or VRE; however, the impact on hospital-acquired infection rates (HAI) has not been assessed systematically. Methods Retrospective multicenter interrupted time series between 2002 and 2017 at three academic hospitals. Participating hospitals discontinued CP for patients with contained body fluids who were colonized or infected with MRSA or VRE. The primary intervention was stopping the use of CP. Secondary interventions were horizontal infection prevention strategies. The primary outcomes were rates of central line-associated bloodstream infections, catheter-associated urinary tract infections, mediastinal surgical site infection, and ventilator-associated pneumonia due to MRSA, VRE, or any organism using Centers for Disease Control and Prevention National Healthcare Safety Network surveillance definitions. Results Central line-associated bloodstream infections, catheter-associated urinary tract infections, mediastinal surgical site infection, and ventilator-associated pneumonia rates trended down at each institution. There were no statistically significant increases in these infections associated with discontinuing CP. Individual horizontal infection prevention strategies variably impacted HAI outcomes. Conclusions Stopping the routine use of CP for patients with contained body fluids who are colonized or infected with MRSA or VRE did not result in increased HAIs. Bundled horizontal infection prevention strategies resulted in sustained HAI reductions.

A novel betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread rapidly across the globe since December 2019. Coronavirus disease 2019 (COVID-19) has a significantly higher mortality rate than seasonal influenza and has disproportionately affected older adults, especially those with cardiovascular disease and related risk factors. Adverse cardiovascular sequelae, such as myocarditis, acute myocardial infarction, and heart failure, have been reported in patients with COVID-19. No established treatment is currently available; however, several therapies, including remdesivir, hydroxychloroquine and chloroquine, and interleukin (IL)-6 inhibitors, are being used off-label and evaluated in ongoing clinical trials. Considering these therapies are not familiar to cardiovascular clinicians managing these patients, this review describes the pharmacology of these therapies in the context of their use in patients with cardiovascular-related conditions.

Antibiotic stewardship programs (ASPs) play a crucial role in controlling the emergence of resistant organisms, reducing rates of Clostridium difficile infections and associated hospital length of stay, promoting judicious use of antibiotics, and minimizing associated adverse events. There is a significant overlap between the goals of infection control programs and ASPs, and both programs can benefit from a synergistic relationship. Hospital epidemiologists can support these programs by providing leadership support, sharing surveillance data, bridging gaps between ASPs and departments such as microbiology, integrating educational programs with ASPs, sharing outbreak alerts, and assisting with the development of treatment algorithms.

A primary strategy of central line-associated bloodstream infection (CLABSI) prevention is standardized, aseptic insertion of central lines. We compared hospital-wide CLABSI rate pre- and post-implementation of a dedicated procedure team as well as central line checklist completion and patient-specific variables between the procedure team and other providers. No significant differences were found. Further CLABSI prevention should focus on central line maintenance.

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.

The impact of formulary restriction and preauthorization (FRPA) on prescribing trends was examined over a 5-year period at an academic medical center. Ordinary least squares regression was used to identify hospital units demonstrating statistically significant trends in prescription of restricted agents. Significant decreases in restricted drug use were seen on 2 of 7 medicine units subject to FRPA, whereas a significant increase was seen in 1 of 4 surgical units subject to FRPA.

We assessed the impact of an embedded electronic medical record decision-support matrix (Cerner software system) for the reduction of hospital-onset Clostridioides difficile. A critical review of 3,124 patients highlighted excessive testing frequency in an academic medical center and demonstrated the impact of decision support following a testing fidelity algorithm.

We investigated the impact of discontinuation of contact precautions for methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus infected or colonized patients on central-line associated bloodstream infection rates at an academic children’s hospital. Discontinuation of contact precautions with a bundled horizontal infection prevention platform resulted in no adverse impact on CLABSI rates.

Highlights • Fungal superinfection is a concern in patients who are hospitalized with COVID-19. • There is concern that the COVID-19 pandemic will lead to the overuse of antifungals. • Antifungal use was not increased early in the COVID-19 pandemic at an academic medical center.

Background Cascade reporting (CR) is a strategy of reporting antimicrobial susceptibility test results in which secondary agents are only reported if an organism is resistant to primary, narrow spectrum agents within a drug class. A multidisciplinary team developed CR algorithms for Gram-negative bacteria based on the local antibiogram and infectious diseases practice guidelines. Methods CR was implemented at a 399-bed tertiary care VAMC in March 2018. In a quasi-experimental study, antimicrobial use data across 8 inpatient units were extracted from the CDC’s NHSN AU module from April 2017 – March 2019 (12 months pre- and post-implementation of CR), reported as antimicrobial days of therapy (DOT) per 1000 days present (DP). T-tests and linear mixed models accounting for seasonal and random unit effects were used to compare antimicrobial use pre- and post-CR implementation. Figure 1A. Cascade reporting algorithm for antimicrobial susceptibility reporting for Enterobacteriaceae Figure 1B. Cascade reporting algorithm for antimicrobial susceptibility reporting for Pseudomonas aeruginosa Results Following CR implementation, mean monthly meropenem (p=0.005) and piperacillin/tazobactam (p=0.002) use decreased, while cefepime use increased (p< 0.001). The slope of ciprofloxacin use decreased by 2.16 DOTs/1,000 DP per month (SE=0.25, p< 0.001). The slope of cefpodoxime and moxifloxacin use decreased by 18% (p< 0.001), and 7% (p< 0.001), respectively. The slope of cephalexin use decreased by 0.55 DOTs/1,000 DP (SE=0.26, p< 0.001). The slope of ceftriaxone and cefepime use increased by 1.51 (SE=0.59, p=0.011) and 1.06 (SE=.32, p=0.002) DOTs/1000 DP per month, respectively. There were no significant changes in the slope of amoxicillin/clavulanate, levofloxacin, or meropenem consumption. Rates of Clostridioides difficile infection did not significantly change. Figure 2A. Average monthly use of oral antibiotics across all units in average days of therapy (DOTs) per 1000 days present.

Average monthly use of intravenous antibiotics across all units in average days of therapy (DOTs) per 1000 days present. CR = Cascade reporting. Table 1. Slope of Antimicrobial Utilization Pre and Post-Cascade Reporting Implementation. Conclusion After implementation of CR, the slope of ciprofloxacin use decreased and mean monthly meropenem use decreased. CR is a valuable tool that can be employed by ASPs to encourage optimal use of antibiotics. Disclosures All Authors: No reported disclosures

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.

Background: Central-line–associated blood stream infections (CLABSIs) are linked with significant morbidity and mortality. A NHSN laboratory-confirmed bloodstream infection (LCBSI) has specific criteria to ascribe an infection to the central line or not. The criteria used to associate the pathogen to another site are restrictive. This objective to better classify CLABSIs using enhanced criteria to gain a comprehensive understanding of the error so that appropriate reduction efforts are utilized. Methods: We conducted a retrospective review of medical records with NHSN-identified CLABSI from July 2017 to December 2018 at 2 geographically proximate hospitals. Trained infectious diseases personnel from tertiary-care academic medical centers, the University of Virginia Health System, a 600-bed medical center in Charlottesville, Virginia, and Virginia Commonwealth University Health System with 865 beds in Richmond, Virginia, reviewed charts. We defined “overcaptured” or O-CLABSI into different categories: O-CLABSI-1 is bacteremia attributable to a primary infectious source; O-CLABSI-2 is bacteremia attributable to neutropenia with gastrointestinal translocation not meeting mucosal barrier injury criteria; O-CLABSI-3 is a positive blood culture attributable to a contaminant; and O-CLABSI-4 is a patient injecting line, though not officially documented. Descriptive analyses were performed using the χ2 and the Fisher exact tests. Results: We found a large number of O-CLABSIs on chart review (79 of 192, 41%). Overall, 56 of 192 (29%) LCBSIs were attributable to a primary infectious source not meeting NHSN definition. O-CLABSI proportions between the 2 hospitals were statistically different; hospital A identified 34 of 59 (58%) of their NHSN-identified CLABSIs as O-CLABSIs, and hospital B identified a 45 of 133 (34%) as O-CLABSIs (P = .0020) (Table 1). When comparing O-CLABSI types, hospital B had a higher percentage of O-CLABSI-1 compared to hospital B: 76% versus 64%. Hospital A had a higher proportion of O-CLABSI-2: 21 versus 7%. Hospitals A and B had similar proportion of O-CLABSI-3: 15% versus 18%. These values were all statistically significant (P < .0001). Discussions: The results of these 2 geographically proximate systems indicate that O-CLABSIs are common. Attribution can vary significantly between institutions, likely depending on differences in incidence of true CLABSI, patient populations, protocols, and protocol compliance. These findings have implications for interfacility comparisons of publicly reported data. Most importantly, erroneous attribution can result in missed opportunity to direct patient safety efforts to the root cause of the bacteremia and could lead to inappropriate treatment.Funding: NoneDisclosures: Michelle Doll, Research Grant from Molnlycke Healthcare

Background: Quantification of the magnitude of CRE both within a facility and regionally poses a challenge to healthcare institutions. Periodic point-prevalence surveys are recommended by the CDC CRE tool kit as a facility-level prevention strategy. A 2016 point-prevalence survey of 2 high-risk units at a tertiary-care center in the United States for CRE colonization found that all patients surveyed were negative for CRE. The infection prevention (IP) team repeated the study in 2019 to reassess the prevalence of CRE in the healthcare facility. Methods: A point-prevalence survey was performed in November 2019 on the same 2 high-risk units surveyed in 2016. A perirectal flocked swab was collected from all patients unless a patient refused and/or a contraindication to rectal swab was present. Swabs were inoculated onto HardyChrom TM CRE agar for incubation in ambient air at 35°C for 24 hours. Organism identification was performed using MALDI-TOF mass spectrometry on a MBT Smart by Bruker. Results: None of the patients on either high-risk unit was known to be colonized or infected with CRE at the time of the point-prevalence survey. Of 41 perirectal swabs collected, 4 (9.8%) were positive for CRE. None (0 of 20) were surgical ICU patients and 4 of 21 (19%) were medical ICU patients. All positive swabs revealed different organisms identified as follows: Escherichia coli, Enterobacter cloacae, Enterobacter kobai, and Enterobacter aerogenes. All 4 positive patients had had recent contact with multiple acute-care hospitals. Also, 2 had been transferred for liver transplant evaluation. None of these patients had received a carbapenem during their admission to the facility. Conclusion: CRE are increasingly identified in healthcare centers in the United States. Centers previously classified as low prevalence will need to maintain preventive strategies to limit transmission risks as colonized patients arrive in the facility for care. Adoption of a robust horizontal infection prevention program may be an effective strategy to avoid the spread of CRE.Funding: NoneDisclosures: Michelle Doll reports a research grant from Molnlycke Healthcare.

Background: Updated IDSA-SHEA guidelines recommend different diagnostic approaches to C. difficile depending on whether There are pre-agreed institutional criteria for patient stool submission. If stool submission criteria are in place, nucleic acid amplification testing (NAAT) alone may be used. If not, a multistep algorithm is suggested, incorporating various combinations of toxin enzyme immunoassay (EIA), glutamate dehydrogenase (GDH), and NAAT, with discordant results adjudicated by NAAT. At our institution, we developed a multistep algorithm leading with NAAT with reflex to EIA for toxin testing if NAAT is positive. This algorithm resulted in a significant proportion of patients with discordant results (NAAT positive and toxin EIA negative) that some experts have categorized as possible carriers or C. difficile colonized. In this study, we describe the impact of a multistep algorithm on hospital-onset, community-onset, and healthcare-facility–associated C. difficile infection (HO-CDI, CO-CDI, and HFA-CDI, respectively) rates and the management of possible carriers. Methods: The study setting was a 399-bed, tertiary-care VA Medical Center in Richmond, Virginia. A retrospective chart review was conducted. The multistep C. difficile testing algorithm was implemented June 4, 2019 (Fig. 1). C. difficile testing results and possible carriers were reviewed for the 5 months before and 4 months after implementation (January 2019 to September 2019). Results: In total, 587 NAATs were performed in the inpatient and outpatient setting (mean, 58.7 per month). Overall, 123 NAATs (21%) were positive: 59 in the preintervention period and 63 in the postintervention period. In the postintervention period, 23 positive NAATs (26%) had a positive toxin EIA. Based on LabID events, the mean rate of HO+CO+HCFA CDI cases per 10,000 bed days of care (BDOC) decreased significantly from 9.49 in the preintervention period to 1.15 in the postintervention period (P = .019) (Fig. 2). Also, 9 of the possible carriers (22%) were treated for CDI based on high clinical suspicion, and 6 of the possible carriers (14%) had a previous history of CDI. Of these, 5 (83%) were treated for CDI. In addition, 1 patient (2%) converted from possible carrier to positive toxin EIA within 14 days. The infectious diseases team was consulted for 11 possible carriers (27%). Conclusions: Implementation of a 2-step C difficile algorithm leading with NAAT was associated with a lower rate of HO+CO+HCFA CDI per 10,000 BDOC. A considerable proportion (22%) of possible carriers were treated for CDI but did not count as LabID events. Only 2% of the possible carriers in our study converted to a positive toxin EIA.Funding: NoneDisclosures: None

Background: Fluoroquinolones (FQs) are one of the most commonly prescribed antibiotic classes in the United States. In recent years, their widespread use has come under heightened scrutiny due potential adverse drug reactions including risks of mental health side effects, serious blood sugar disturbances, and Food and Drug Administration (FDA) black-box warnings for tendinopathy, aortic aneurysm, and dissection. These warnings prompted the Department of Veterans Affairs Pharmacy Benefits Management Service to perform a nationwide FQ utilization review, which identified our facility for potential overuse of FQs in the outpatient setting: 82.2 prescriptions per 1,000 unique patients compared to an average of 48 prescriptions per 1,000 unique patients across all VHA facilities. We then embarked on a FQ medication use evaluation (MUE). Objective: To determine appropriateness of FQ prescribing practices in the outpatient setting. Methods: The study setting was a 399-bed tertiary-care Veterans Hospital with >250 affiliated outpatient clinics in Richmond, Virginia. A retrospective chart review was conducted on a convenience sample of consecutive patients prescribed an FQ from each quarter between April 1, 2018, and March 31, 2019. Chart review included patient demographics, location, FQ used, dose, indication, appropriateness, prescriber, and documentation of patient counseling on FDA black box warnings. Appropriate treatment was defined by national and local antimicrobial therapy guidelines. Results: In total, 265 patients were included the study. Among them, 233 patients (88%) were men and the mean age was 68 years. Overall, 127 patients (48%) were prescribed FQs inappropriately. Primary care clinics and the emergency department (ED) had the highest frequency of inappropriate FQ prescriptions (Fig. 1). Moreover, 92 patients (35%) were prescribed FQs for surgical prophylaxis prior to urological procedures. FQs were most commonly inappropriately prescribed for urinary tract infection (UTI, n =74, 84%) and upper respiratory tract infection (URI, n=27, 84%) (Fig. 2). Documented counseling on FDA black box warnings occurred in 82 cases (31%). Conclusions: In our MUE, outpatient prescribing of FQs was inappropriate nearly 50% of the time. The most commonly documented indications for FQs determined to be inappropriate included UTI and URI. Inappropriate prescriptions most commonly originated from primary care and the emergency department. Urology had the highest volume of FQ prescriptions, which were mostly appropriate surgical prophylaxis based on indication (though an alternative agent would be preferred based on local resistance rates). Documentation of patient counseling for FDA black-box warnings on FQs was uncommon.Funding: NoneDisclosures: None

• Improvements to the electronic medical records must occur prior to the next pandemic. • During pandemics, infection preventionists’ should advise staff, not review charts. • Automation can help improve healthcare safety and quality.

Touchless ultraviolet disinfection (UVD) devices effectively reduce the bioburden of epidemiologically relevant pathogens, including Clostridium difficile. During a 25-month implementation period, UVD devices were deployed facilitywide for the terminal disinfection of rooms that housed a patient who tested positive for C difficile. The deployment was performed with structured education, audit and feedback, and resulted in a multidisciplinary practice change that maximized the UVD capture rate from 20% to 100%.

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.

General guidance for personal protective equipment (PPE) is provided by the Occupational Safety and Health Administration and the United States Centers for Disease Control and Prevention. Previous research of PPE demonstrates the ability of gloves to harbor infectious pathogens. We surveyed health care workers to investigate current PPE practices during linen removal from patient rooms and during patient transport. The results suggest a possible risk for cross-contamination of the environment from overuse of gloves.

Interest in electronic hand hygiene monitoring systems (EHHMSs) is now widespread throughout the infection control community. We tested 2 types of EHHMS for accuracy. The type B EHHMS captured more HH events with superior accuracy. Hospitals considering an EHHMS should assess the technology’s ability to accurately capture HH performance in the clinical workflow.

The purpose of this article is to perform a systematic review over the past 5 years on the role and effectiveness of clinical decision support systems (CDSSs) on antibiotic stewardship. CDDS interventions found a significant impact on multiple outcomes relevant to antibiotic stewardship. There are various types of CDSS implementations, both active and passive (provider initiated). Passive interventions were associated with more significant outcomes; however, both interventions appeared effective. In the reviewed literature, CDSSs were consistently associated with decreasing antibiotic consumption and narrowing the spectrum of antibiotic usage. Generally, guideline adherence was improved with CDSS, although this was not universal. The effect on other outcomes, such as mortality, Clostridiodes difficile infections, length of stay, and cost, inconsistently showed a significant difference. Overall, CDDS implementation has effectively decreased antibiotic consumption and improved guideline adherence across the various types of CDSS. Other positive outcomes were noted in certain settings, but were not universal. When creating a new intervention, it is important to identify the optimal structure and deployment of a CDSS for a specific setting.

We used multivariable analyses to assess whether meeting core elements was associated with antibiotic utilization. Compliance with 7 elements versus not doing so was associated with higher use of broad-spectrum agents for community-acquired infections [days of therapy per 1,000 patient days: 155 (39) vs 133 (29), P = .02] and anti-methicillin-resistant S. aureus agents [days of therapy per 1,000 patient days: 145 (37) vs 124 (30), P = .03].

In a 12-month study, a nurse driven protocol was implemented at a tertiary academic medical center. The purpose of the nurse driven protocol was to identify community-onset Clostridioides difficile infections, expeditiously isolate patients with presumed C difficile diarrheal illness, and prevent transmission while simultaneously decreasing the incidence of hospital-onset C difficile. The overall adherence to fidelity of the protocol was poor and failed to have a significant impact on infection rates.

We implemented an electronic medical record (EMR) decision support tool for ordering urine cultures per evidence-based guidelines. Following the EMR change, we found a significant increase in proportion of cultures ordered for catheterized intensive care unit (ICU) patients meeting guidelines. We surveyed providers and found poor understanding of urine culture guidelines for catheterized ICU patients. EMR-based interventions and educational opportunities have potential to improve urine culture guideline adherence and reduce unnecessary testing and antibiotic use.

To summarize the extent to which hospital-acquired infections (HAIs) are preventable and to assess expectations, challenges, and barriers to improve patient outcomes. HAIs cause significant morbidity and mortality. Getting to zero HAIs is a commonly stated goal yet leads to unrealistic expectations. The extent to which all HAIs can be prevented remains debatable and is subject to multiple considerations and barriers. Current infection prevention science is inexact and evolving. Evidence-based infection prevention practices are often incompletely implemented and at times controversial. Highly sensitive surveillance results in overdiagnosis, calling into question the real incidence of HAIs. Perceived reductions in HAIs by gaming the system lead to false conclusions about preventability and may cause harm. Successful HAI reduction programs require executive oversight yet keeping hospital leaders engaged in infection prevention is a challenge given competing priorities. Medicine is not a physical science with precisely defined laws; thus, infection prevention interventions are subject to variable outcomes. Perhaps up to 55–70% of HAIs are potentially preventable. This is subject to a law of diminishing returns as the preventable proportion of HAIs may reduce over time with improvements in patient safety. As the principle tenet of medicine is first do no harm, infection prevention programs should relentlessly pursue reliable, sustainable, and practical strategies for heightened patient safety.

A novel antimicrobial consumption metric designed to identify the proportion of carbapenem consumption (PoCC) among broad-spectrum antipseudomonal antimicrobials has been shown to vary significantly by US Census Bureau region. This retrospective surveillance study identified significant total PoCC variability (27%; P = .001) across 8 inpatient units from January 2017 through June 2018. This metric may be useful in identifying and comparing inpatient units that may be overusing antipseudomonal carbapenems.

New controversies in the diagnosis and prevention of Clostridiodes difficile are challenging and at times changing infection control practice at many medical centers. Molecular epidemiologic studies are changing our understanding of C. difficile and its spectrum of disease. C. difficile as a hospital-acquired infection is likely largely overdiagnosed given overly sensitive molecular testing and widespread colonization of ill or debilitated patients. Clostridiodes difficile infection continues to challenge infection prevention programs. Shifts in our understanding of the epidemiology of this organism and its spectrum of clinical presentations are changing the approach to prevention efforts. Nevertheless, cleanliness of the healthcare environment and antimicrobial stewardship remain core risk reduction strategies. Other strategies such as screening and isolation are inciting controversy. The optimal infection prevention strategies for C. difficile remain the subject of intense study and debate.

Background Full compliance with personal protective equipment (PPE) is challenging, with multiple barriers noted: adherence to appropriate PPE, lack of knowledge of appropriate PPE, added time to workflow, and appropriate donning/doffing techniques of PPE to avoid self-contamination. Recent studies note that nurses tend to batch care to achieve more while in the room. A hand hygiene technology system alerted MRICU nurses to difficulties performing WHO’s Five Moments of hand hygiene (HH) when in contact precaution PPE. Methods We implemented the ‘Plan-Do-Study-Act’ (PDSA) framework to address the MRICU team concerns. Six nurses were directly observed while providing bedside care to understand nursing workflow and barriers to HH while in contact precautions. Results All 6 nurses performed hand hygiene prior to entering the room and at the time of exiting the room. Once donning contact precautions, they had variable but low compliance with any additional HH opportunities. The average missed opportunities per encounter was 5.2 (range: 2-11). Moments that would require hand washing or sanitizer if nurse were not gloved were not met with changing gloves. An average of 9.8 tasks were achieved in each room (range: 3-18). On average, each visit was 16 (range: 4-30 minutes) minutes long. Conclusion There is significant opportunity for improved HH while in PPE. Nurses may be more aware of the “Five moments” when not wearing gloves in contact precaution rooms, but lose the trigger once the gloves are on in the contact precaution rooms. An education campaign to improve hand sanitizer usage with gloves is the next step in this PDSA. More prominent placement of glove boxes in the rooms will also serve as a trigger to remind nurses to change gloves after certain tasks. Limitations of this PDSA cycle include Hawthorne effect of the nurses knowing they were observed and potentially changing their workflow. We also only observed morning workflow; nurses on different shifts may have different workflow. Disclosures All Authors: No reported disclosures

Healthcare workers routinely self-contaminate even when using personal protective equipment. Observations of donning/ doffing practices on inpatient units along with surveys were used to assess the need for a personal protective equipment training program. In contrast to low perceived risk, observed doffing behaviors demonstrate significant personal protective equipment technique deficits.Infect Control Hosp Epidemiol 2017;38:226–229

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.

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life.

Background Anesthesia workstations (AWs) are a reservoir for pathogenic organisms potentially associated with surgical site infections. This study examined the effectiveness of the Tru-D SmartUVC device (Tru-D LLC, Nashville, TN) on bioburden reduction (BR) on AWs. Methods Strips of tissue inoculated with a known concentration of either Staphylococcus aureus , Enterococcus faecalis , or Acinetobacter sp were placed on 22 high-touch surfaces of an AW. Half of the AW surfaces received direct ultraviolet (UV) light exposure and half received indirect exposure. Two inoculated strips, in sterile tubes outside of the room, represented the control. Trials were conducted on AWs in an operating room and a small room. Strips were placed in a saline solution, vortexed, and plated on blood agar to assess BR by the number of colony forming units. Results All experimental trials, compared with controls, exhibited a BR >99%. There was a significantly greater reduction of E faecalis colony forming units in the operating room AW under direct exposure ( P = .019) compared with indirect exposure. There was no significant difference in reduction when comparing AWs between rooms. Conclusion Regardless of room size and exposure type, automated UV-C treatment greatly influences BR on AW high-touch surfaces. Hospitals instituting an automated UV-C system as an infection prevention adjunct should consider utilizing it in operating rooms for BR as part of a horizontal infection prevention surgical site infection-reduction strategy.
