Authors: Mirza Muzna , Wattenmaker Lauren , Clunis Odion , Vance Wendy , Moon Shunte , Pollock Daniel 
Published: November 2020

Background:
The CDC National Healthcare Safety Network (NHSN) is the nation’s most widely used healthcare-associated infection (HAI) and antibiotic use and resistance (AUR) surveillance system. More than 22,000 healthcare facilities report data to the NHSN. The NHSN data are used by facilities, the CDC, health departments, the CMS, among other organizations and agencies. In 2017, the CDC updated the NHSN Agreement to Participate and Consent (Agreement), completed by facilities, broadening health department access to NHSN data and extending eligibility for data use agreements (DUAs) to local and territorial health departments. DUAs enable access to NHSN data reported by facilities in the health department’s jurisdiction and have been available to state health departments since 2011. The updated agreement also enables the CDC to provide NHSN data to health departments for targeted prevention projects outbreak investigations and responses. Methods: We reviewed the current NHSN DUA inventory to assess the extent to which health departments use the NHSN’s new data access provisions and used semistructured interviews with health department staff, conducted via emails, phone, and in person conversations, to identify and describe their NHSN data uses. Results: As of late 2019, the NHSN has DUAs with health departments in 17 states, 7 local health departments (including municipalities and counties), and 1 US territory. The NHSN also has received requests from 2 state health departments for data supporting HAI prevention projects. Health departments with DUAs described improved relationships with facilities in their jurisdictions because of new opportunities to offer NHSN data analysis assistance to facilities. One local health department analyzed their NHSN carbapenem-resistant Enterobacteriaceae (CRE) data to identify (1) facilities in its jurisdiction with comparatively high CRE infection burden and (2) geographic areas to target for a CRE isolate submission program. Outreach to facilities with high CRE burden led to enrollment of 15 clinical laboratories into a voluntary isolate submission program to analyze CRE isolates for additional characterization. Examples of health departments’ use of data for action include: notifying facilities with high standardized infection ratios (SIRs) and sharing Targeted Assessment for Prevention (TAP) reports. Conclusions: The NHSN’s role as a shared surveillance resource has expanded in multiple public health jurisdictions as a result of new data access provisions. Health departments are using NHSN data in their programmatic responses to HAI and AR challenges. New access to NHSN data is enabling public health jurisdictions to assess problems and opportunities, provide guidance for prevention projects, and support program evaluations.Funding: NoneDisclosures: None
From Little Things Big Things Grow: The Development of an Auditing Program to Assess the Quality of Antimicrobial Prescribing
Authors: James Rodney , Chen Caroline , Buising Kirsty , Thursky Karin , Ierano Courtney 
Published: November 2020

Background: An important aspect of antimicrobial stewardship is the qualitative assessment of antimicrobial prescribing. Owing to lack of standardized tools and resources required to design, conduct and analyze qualitative audits, these assessments are rarely performed. Objective: We designed an audit tool that was appropriate for all Australian hospital types, suited to local user requirements and including an assessment of the appropriateness of antimicrobial prescribing. Methods: In 2011, a pilot survey was conducted in 32 Australian hospitals to assess the usability and generalizability of a qualitative audit tool. The tool was revised to reflect the respondents’ feedback. A second study was performed in 2012 in 85 hospitals. In 2013, following further feedback and refinement, an online auditing tool, the Hospital National Antimicrobial Prescribing Survey (NAPS), was developed. Early audits demonstrated that surgical prophylaxis had the highest rates of inappropriate prescribing. In 2016, the Surgical NAPS was developed to further investigate reasons for this, and the NAPS program was further expanded to audit antimicrobial prescribing practices in Australian aged-care homes (ie, the Aged Care NAPS). Results: Between January 1, 2013, and November 12, 2019, 523 Australian public and private hospitals (53.8%) utilized the Hospital NAPS; 215 (22.1%) have utilized the Surgical NAPS; and 774 of Australian aged-care homes (29.0%) have utilized the Aged Care NAPS. National reporting has identified key target areas for quality improvement initiatives at both local and national levels. The following initiatives have been outlined in 14 public reports: improved documentation; prolonged antimicrobial prophylaxis; compliance with prescribing guidelines; appropriateness of prescribing; access to evidence-based guidelines; and improved microbiology sampling. Conclusions: By utilizing the Plan-Do-Study-Act cycle for healthcare improvement and by involving end users in the design and evaluation, we have created a practical and relevant auditing program to assess both quantitative and qualitative aspects of antimicrobial prescribing in a wide range of settings. This voluntary program is now endorsed by the National Strategy for Antimicrobial Resistance Surveillance, partners with the Antimicrobial Use and Resistance in Australian Surveillance System, and is utilized by facilities to meet mandatory national accreditation standard requirements. With the success of the NAPS program in Australia, it has now been implemented in New Zealand, Canada, Malaysia, Fiji, and Bhutan, with plans for other countries to implement the program soon. Current research is being conducted to expand the program to include audits for family physicians, veterinarians, and remote indigenous communities, and for antifungal use.Disclosures: NoneFunding: None

Published: November 2020

Background: The epidemic NAP1/027 Clostridioides difficile strain (MLST1, ST1) that emerged in the mid-2000 is on the decline. The current distribution of C. difficile strain types and their transmission dynamics are poorly defined. We performed whole-genome sequencing (WGS) of C. difficile isolates in 2 regions to identify the predominant multilocus sequence types (MLSTs) in community- and healthcare-associated cases and potential transmission between cases using whole-genome single-nucleotide polymorphism (SNP) analysis. Methods: Isolates were collected through the CDC Emerging Infections Program population-based surveillance for C. difficile infections (CDI) for 3 months between 2016 and 2017 in 5 Minnesota counties and 1 New York county. Isolates were limited to incident cases (CDI in a county resident with no positive C. difficile test in the preceding 8 weeks). Cases were classified as healthcare associated (HA-CDI) or community associated (CA-CDI) based on healthcare exposures as previously described. WGS was performed on an Illumina Miseq. The CFSAN (FDA) pipeline was used to compute whole-genome SNPs, SPAdes was used for assembly, and MLST was assigned according to www.pubmlst.org. Results: Of 431 isolates, 269 originated from New York and 162 from Minnesota; 203 cases were classified as CA-CDI and 221 as HA-CDI. The proportion of CA-CDI cases was higher in Minnesota than in New York: 62% vs 38%. The predominant MLSTs across both sites were ST42 (9%), ST8 (8%), and ST2 (8%). MLSTs more frequently encountered in HA-CDI than CA-CDI included ST1 (note that this ST includes PCR Ribotype 027; 76% HA-CDI), ST53 (84% HA-CDI), and ST43 (80% HA-CDI). In contrast, ST110 (63% CA-CDI) and ST3 (67% CA-CDI) were more commonly isolated from CA-CDI cases. ST1 accounted for 7.6% of circulating strains and was more common in New York than Minnesota (10% vs 3%) and was concentrated among New York HA-CDI cases. Also, 412 isolates (1 per patient) were included in the final whole-genome SNP analysis. Of these, only 12 pairs were separated by 0–3 SNPs, indicating potential transmission, and most involved HA-CDI cases. ST1, ST17, and ST46 accounted for 8 of 12 pairs, with ST17 and ST46 potentially forming small clusters. Conclusions: This analysis provides a snapshot of the current genomic epidemiology of C. difficile across 2 geographically and epidemiologically distinct regions of the United States and supports other studies suggesting that the role of direct transmission in the spread of CDI may be limited.Funding: NoneDisclosures: None
Hospital Outbreak of Respiratory Syncytial Virus in Neonatal Intensive Care Unit: The Risk of Admitting External Patients
Authors: Mendes Elisa Teixeira , Souza s Bomediano , Paranhos Hadassa Louback , Santos Isabela Cristina Moreira 
Published: November 2020

Background: Acute viral bronchiolitis caused by respiratory syncytial virus (RSV) may be a manifestation of high severity in neonatal-ICU (NICU) patients, with high risk of in-hospital cross transmission and outbreaks. During the epidemic seasonal period, intense viral circulation occurs in community; thus, transmission in the NICU is difficult to control. Objective: We describe an outbreak that occurred in a NICU in a public hospital in So Paulo state, Brazil. We also discuss the role of admitting external newborns with community-acquired virus in the incidence of these outbreaks in the NICU. Methods: In 2017 in Campinas, an RSV epidemic occurred during the seasonal period, resulting in a outbreak at the Campinas maternity hospital. A retrospective investigation was performed, and patients were analyzed for clinical and epidemiological characteristics and for risk factors for poor prognosis. We included neonates admitted in NICU with positive nasal lavage for RSV from April to July 2017. Statistical analysis were performed with 2 test for the categorical variables and the Student t test for the continuous variables comparing the newborn group from the community (external) with infected newborns in the hospital (internal). P < .05 was considered significant. Results: Of 44 neonates with RSV during this period, 32 were external and 12 were internal (Fig. 1). The mean gestational age of the external neonates was 38 weeks and 2 days, whereas the mean gestational age of the internal neonates was 29 weeks and 1 day (P < .001). The hospitalization time was higher in the internal group (P < .001). Table 1. One death associated with infection occurred in the internal group. Community neonates (external group) were mostly term-born, with no comorbidities, and they had a more favorable clinical course. In the literature, neonates infected with RSV at the hospital have several risk factors for poor prognosis, with a 13.5% mortality rate. Discussion: RSV outbreaks have great relevance in hospital settings, especially in the NICU, where there are a large number of vulnerable patients and a high risk of in-hospital cross transmission. Neonates infected with RSV at the hospital have several risk factors for poor prognosis, including high mortality. Therefore, it is important to discuss the exposure of this population to community-based infectious agents, mainly viral, and the risk of accepting patients from the community to be admitted to the NICU.Funding: NoneDisclosures: None
How Standard Are Standard Precautions? Knowledge and Attitudes Toward Standard Precautions at an Academic Medical Center
Authors: Faller Rebecca , Sampathkumar Priya , Ung Stacy (Tram) 
Published: November 2020

Background: Standard precautions are the basis of infection prevention and include a set of common-sense infection control practices that prevent transmission of diseases acquired by contact with blood, body fluids, nonintact skin, and mucous membranes. These measures include hand hygiene, personal protective equipment (PPE), cleaning and disinfecting, linen handling, waste disposal, sharps safety and respiratory etiquette. Standard precautions require that the risk for exposure be assessed and appropriate precautions taken based on risk. Observations and anecdotal evidence have led us to believe that understanding of standard precautions is lacking among healthcare personnel. Methods: A survey was conducted at a large health system to assess knowledge and practices related to specific elements of standard precautions. Results: More than 3,000 HCWs responded from inpatient settings (41%), outpatient settings (37%), and both settings (22%). Nurses comprised the majority of respondents (54%), and others included physicians (9%), respiratory therapists, as well as physical and occupational therapists. Discussion: The vast majority (96%) of respondents agreed that standard precautions were required in the care of all patients, but a significant proportion (34%) interpreted that to mean that standard precautions always involve wearing gloves, and 22.5% thought that PPE was always required for standard precautions. Hand hygiene and sharps safety were identified as the best understood elements of standard precautions. Respiratory etiquette and cleaning and disinfection were reported as the least understood elements, with PPE, waste disposal, and linen handling also being reported as inadequately understood components of standard precautions (Fig. 1). Conclusions: In an era of increasing drug resistance and fewer effective antibiotics, standard precautions are our best defense against the spread of infections in the healthcare setting. Our survey showed that there is room for improvement among healthcare workers in understanding of the elements of standard precautions. We plan to use the survey to craft a targeted education campaign to improve understanding of and adherence to standard precautions.Funding: NoneDisclosures: None
Identification of Aminoglycoside Resistance Genes From Bacteria Isolated From Selected Municipal Drinking Water Distribution Systems in Southwestern Nigeria
Authors: Adesoji Ayodele T. , Ogunjobi Adeniyi A. 
Published: November 2020

Background: Multidrug-resistant bacteria can lead to treatment failure, resulting in infectious diseases being transferred through nonpotable water. Aminoglycosides are an important class of antibiotics that are abused in Nigeria. Few studies have investigated aminoglycoside-modifying genes (AMGs) that are likely responsible for resistance in Nigeria bacteria isolates. Therefore, we aimed to characterize AMGs from isolates in drinking water distribution systems (DWDS) in southwestern Nigeria. Methods: Multidrug-resistant bacteria (n = 181) that had been previously characterized by 16S rDNA sequencing and that were positive for resistance to at least 1 aminoglycoside antibiotic were selected from 6 treated and untreated water distribution systems. Strains were PCR genotyped for 3 AMGs: aph(3)c, ant(3)b and aph(6)-1dd. Results: Of 181 MDR bacteria tested, 69 (38.12%) were positive for at least 1 of the AMGs. The most common was ant(3)c (27.6%), followed by aph(3")c (18.23%). Both aph(3)c and ant(3")b were found in 7.73% of tested isolates, ant(3)b was most commonly found in Alcaligenes spp (50%). Furthermore, aph(3")c was most commonly detected in Proteus spp (50%). Other genera positive for AMGs included Acinetobacter, Aeromonas, Bordetella, Brevundimonas, Chromobacterium, Klebsiella, Leucobacter, Morganella, Pantoae, Proteus, Providencia, Psychrobacter, and Serratia. Conclusions: High occurrence of ant(3)c and aph(3)c among these bacteria call for urgent attention among public health workers because these genes can be easily disseminated to consumers if present on mobile genetic elements like plasmids, integrons, and transposons.Funding: NoneDisclosures: None
Impact of a Critical National Shortage of Cefazolin on Antimicrobial Practice at a Tertiary-Care Center in Japan
Authors: Murakami Shutaro , Hiroi Junko , Tagashira Yasuaki , Takamatsu Akane , Hasegawa Shinya , Honda Hitoshi 
Published: November 2020

Background: Shortages of essential medicines, a long-standing issue in healthcare, apply equally to antimicrobial agents, a group of essential drugs necessary for sustainable healthcare. The WHO categorized essential medicines into the access, watch, and reserve groups. Older antimicrobials, in particular, were categorized into the access group, meaning that these drugs are in theory widely available at an affordable cost. The shortage of essential antimicrobial agents like cefazolin leads to increased consumption of alternative antimicrobial agents with broad-spectrum activity, which often has the undesirable consequence of defeating antimicrobial stewardship efforts in inpatient settings and potentially promoting antimicrobial resistance. In Japan, cefazolin has been in critically short supply since March 2019. Cefazolin is a first-line agent against common infectious diseases and in surgical antimicrobial prophylaxis, and its shortage has substantially impacted inpatient care. The aim of the present study was to investigate changes in antimicrobial practice at a tertiary-care center in Japan following the emergence of the national cefazolin shortage in March 2019. Methods: Data on each antimicrobial use are logged as days of therapy (DOT) per 1,000 patient days (PD) for antimicrobial stewardship purposes at the study institution. We extracted weekly data from September 2018 to September 2019 to evaluate the impact of the national cefazolin shortage on antimicrobial use at our tertiary-care center. Changes in weekly antimicrobial use and the weekly incidence of Clostridium difficile infections were analyzed by interrupted time series analysis. We also investigated changes in antimicrobial practice at selected situations. Results: As weekly cefazolin use significantly declined after the emergence of the national shortage, use of third-generation cephalosporin (+18.9 DOT per 1,000 PD for intercept [P < .001] and +0.65 DOT per 1,000 PD per week for trend [P = .037]) and clindamycin (18 DOT per 1,000 PD for intercept [P = .008] and 0.12 DOT per 1,000 PD per week for trend [P = .003]) significantly increased. Significant changes in antimicrobial practice were also observed in surgical antimicrobial prophylaxis: third-generation cephalosporin use increased from 1.0% (31 of 3,032) to 62.9% (2,237 of 3,554) (P < .001). However, no significant change in the incidence of Clostridium difficile infection was observed during the study period: +1.72 per 10,000 PD for intercept (P = .12) and 0.12 per 10,000 PD per week for the trend (P = .09). Conclusions: The national cefazolin shortage had a significantly negative impact on patient care and led to increased use of alternative, broader-spectrum antimicrobials, which are not ideal choices either for prophylaxis or treatment.Funding: NoneDisclosures: None

Published: November 2020

Background: Manual cleaning is the recommended method of environmental disinfection; it plays a key role in the prevention of healthcare-associated infections. Recently, automated no-touch disinfection technologies, such as ultraviolet (UV) light, have been proposed as a supplement to manual cleaning. However, UV light adds time to the cleaning process and may decrease the quality of manual cleaning. We evaluated the impact of adding UV light on the quality of manual cleaning and on room turnover times. Methods: During January–September 2019, we assessed the thoroughness of disinfection cleaning (TDC) of environmental surfaces in rooms identified for discharge. According to hospital policy, contact precautions rooms use UV light after manual cleaning with an EPA-approved sporicidal agent (bleach). Non–contact precautions rooms are disinfected using quaternary ammonium only. Rooms were identified after patient admission, selected randomly, and marked once discharge orders were placed. Fluorescent markers were applied on high-touch surfaces before discharge and were assessed after the cleaning process was completed. TDC scores were defined as the percentage of cleaned surfaces of the total of examined surfaces. UV-light disinfection time is determined automatically based on room size. We compared TDC scores and manual cleaning times between contact precautions rooms and noncontact precautions rooms. We also calculated UV-light cycle durations. Results: We assessed 2,383 surfaces in 24 contact precautions rooms with UV-light disinfection and 201 noncontact precautions rooms without UV-light disinfection. The TDC score was similar in contact precautions rooms (243 of 273 surfaces) and noncontact precautions rooms (1,835 of 2,110 surfaces; 89% vs 87%). The median manual cleaning time for contact precautions rooms was 56 minutes (IQR, 37–79), and for noncontact precautions rooms the median manual cleaning time was 33 minutes (IQR, 22–43). UV-light use added a median of 49 minutes (IQR, 35–67) to the overall cleaning process. The median turnover time for contact precautions rooms was 156 minutes (IQR, 87–216) versus 58 minutes (IQR, 40–86) in noncontact precautions room. Conclusions: In a setting with an objective assessment of environmental cleaning, there was no difference in quality of manual cleaning between contact precautions rooms (UV light) and noncontact precautions rooms (UV light). Adding UV light following manual disinfection increased the overall cleaning time and delayed room availability.Funding: NoneDisclosures: None

Background: After the Middle East respiratory syndrome coronavirus outbreak in Korea in 2015, the government newly established the additional reimbursement for infection prevention to encourage infection control activities in the hospitals. The new policy was announced in December 2015 and was implemented in September 2016. We evaluated how infection control activities improved in hospitals after the change of government policy in Korea. Methods: Three cross-sectional surveys using the WHO Hand Hygiene Self-Assessment Framework (HHSAF) were conducted in 2013, 2015, and 2017. Using multivariable linear regression model including hospital characteristics, we analyzed the changes in total HHSAF scores according to the survey time. Results: In total, 32 hospitals participated in the survey in 2013, 52 in 2015, and 101 in 2017. The number of inpatient beds per infection control professionals decreased from 324 in 2013 to 303 in 2015 and 179 in 2017. Most hospitals were at intermediate or advanced levels of progress (90.6% in 2013, 86.6% in 2015, and 94.1% in 2017). In a multivariable linear regression model, the total HHSAF scores were significantly associated with hospital teaching status (β coefficient of major teaching hospital, 52.6; 95% CI, 8.9–96.4; P = .018), bed size (β coefficient of 100-bed increase, 5.1; 95% CI, 0.3–9.8; P = .038), and survey time (β coefficient of 2017 survey, 45.1; 95% CI, 19.3–70.9; P = .001). Conclusions: After the national policy implementation, the number of infection control professionals increased, and the promotion of hand hygiene activities was strengthened in Korean hospitals.Funding: NoneDisclosures: None
