ObjectivesThis study assessed antimicrobial stewardship (AMS) and infection prevention (IP) interventions targeting healthcare-associated Clostridioides difficile and carbapenem-resistant Klebsiella pneumoniae (CRKP) infections, their key outcomes and the application of behaviour change principles in these interventions.DesignThis scoping review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines while focusing on acute healthcare settings in both low-to-middle income and high-income countries.Data sourcesThe databases searched were MEDLINE, PubMed, Web of Science and CINAHL between 22 April 2020 and 30 September 2020.EligibilityThe review included peer-reviewed articles published in English language between 2010 and 2019. Studies that focussed on IP and/or AMS interventions primarily targeting C. difficile or CRKP were included. Studies that assessed effectiveness of diagnostic devices or treatment options were excluded from this review.Data extraction and synthesisAn abstraction sheet calibrated for this study was used to extract data on the main study characteristics including the population, intervention and outcomes of interest (antimicrobial use, compliance with IP interventions and risk for C. difficile and CRKP). A narrative synthesis of the results is provided.ResultsThe review included 34 studies. Analysis indicates that interventions targeting C. difficile and CRKP include Education, Surveillance/Screening, Consultations, Audits, Policies and Protocols, Environmental measures, Bundles, Isolation as well as Notifications or alerts (represented using the ESCAPE-BIN acronym). The identified outcomes include antimicrobial use, resistance rates, risk reduction, adherence to contact precautions, hospital stay and time savings. AMS and IP interventions tend to be more adhoc with limited application of behaviour change principles.ConclusionThis scoping review identified the AMS and IP interventions targeting C. difficile and CRKP in healthcare settings and described their key outcomes. The application of behaviour change principles in AMS and IP interventions appears to be limited.

AbstractBackgroundAccording to the European Center for Disease Prevention and Control (ECDC), the EU records an estimated 3.2 million healthcare associated infections (HAIs) and an associated 37,000 deaths annually. A significant proportion of the HAIs burden is attributable to multi-drug resistant pathogens. Infectious diseases remain top on the list of the leading causes of death globally with multi-drug resistant microorganisms (MDROs) playing a significant role.AimsTo assess the breadth of studies on antibiotics stewardship C. diff and Klebsiella pneumoniae in healthcare settings. To identify existing literature on the interventions for reducing healthcare associated C. diff and Klebsiella pneumoniae transmission.MethodsThis scoping review was undertaken and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) guidelines. The specific databases searched included MEDLINE, PubMed, Web of Science Core Collection, and CINAHL. The process for screening articles and data extraction was undertaken in duplicate by two reviewers. A narrative synthesis of the results is provided.ResultsThe review included 34 studies (16 studies on Clostridium difficile and 18 articles focussed on Klebsiella pneumoniae). These interventions include Education, Surveillance/Screening, Consultations, Audits, Policies/Protocols, Environmental disinfection, Bundles, Isolation, and Notifications or alerts (ESCAPE-BIN). A study involving screening, alerts, staff education, and antimicrobial protocols recorded a 75% reduction in the use of targeted antimicrobials. The largest absolute reduction in antimicrobial use of 310 DDs/1000PDs was reported from an intervention that involved audits and feedback systems. The highest improvement (95%) in adherence was reported by an intervention involving the use of an infection prevention bundle and an environmental cleaning protocol.ConclusionAntimicrobial resistance represents a global threat requiring urgent measures to protect lives. Reducing the burden of AMR entails a host of multi-level approaches aimed at curbing transmission of the resistant pathogens, and optimizing the use of antibiotics.

Background: It is well known that contaminated surfaces contribute to the transmission of pathogens in healthcare settings, necessitating the need for antimicrobial strategies beyond routine cleaning with momentary disinfectants. A recent publication demonstrated that application of a novel, continuously active antimicrobial surface coating in ICUs resulted in the reduction of healthcare-associated infections. Objective: We determined the general microbial bioburden and incidence of relevant pathogens present in patient rooms at 2 metropolitan hospitals before and after application of a continuously active antimicrobial surface coating. Methods: A continuously active antimicrobial surface coating was applied to patient rooms in intensive care units (ICUs) twice over an 18-month period and in non-ICUs twice over a 6-month study period. The environmental bioburden was assessed 8–16 weeks after each treatment. A 100-cm2 area was swabbed from frequently touched areas in patient rooms: patient chair arm rest, bed rail, TV remote, and backsplash behind the sink. The total aerobic bacteria count was determined for each location by enumeration on tryptic soy agar (TSA); the geometric mean was used to compare bioburden before and after treatment. Each sample was also plated on selective agar for carbapenem-resistant Enterobacteriaceae (CRE), vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus (MRSA), and Clostridioides difficile to determine whether pathogens were present. Pathogen incidence was calculated as the percentage of total sites positive for at least 1 of the 4 target organisms. Results: Before application of the antimicrobial coating, total aerobic bacteria counts in ICUs were >1,500 CFU/100 cm2, and at least 30% of the sites were positive for a target pathogen (ie, CRE, VRE, MRSA or C. difficile). In non-ICUs, the bioburden before treatment was at least 500 CFU/100 cm2, with >50% of sites being contaminated with a pathogen. After successive applications of the surface coating, total aerobic bacteria were reduced by >80% in the ICUs and >40% in the non-ICUs. Similarly, the incidence of pathogen-positive sites was reduced by at least 50% in both ICUs and non-ICUs. Conclusions: The use of a continuously active antimicrobial surface coating provides a significant (P < .01) and sustained reduction in aerobic bacteria while also reducing the occurrence of epidemiologically important pathogens on frequently touched surfaces in patient rooms. These findings support the use of novel antimicrobial technologies as an additional layer of protection against the transmission of potentially harmful bacteria from contaminated surfaces to patients.Funding: Allied BioScience provided Funding: for this study.Disclosures: Valerie Beck reports salary from Allied BioScience.

Abstract Objective: To quantitatively evaluate relationships between infection preventionists (IPs) staffing levels, nursing hours, and rates of 10 types of healthcare-associated infections (HAIs). Design and setting: An ambidirectional observation in a 528-bed teaching hospital. Patients: All inpatients from July 1, 2012, to February 1, 2021. Methods: Standardized US National Health Safety Network (NHSN) definitions were used for HAIs. Staffing levels were measured in full-time equivalents (FTE) for IPs and total monthly hours worked for nurses. A time-trend analysis using control charts, t tests, Poisson tests, and regression analysis was performed using Minitab and R computing programs on rates and standardized infection ratios (SIRs) of 10 types of HAIs. An additional analysis was performed on 3 stratifications: critically low (2–3 FTE), below recommended IP levels (4–6 FTE), and at recommended IP levels (7–8 FTE). Results: The observation covered 1.6 million patient days of surveillance. IP staffing levels fluctuated from ≤2 IP FTE (critically low) to 7–8 IP FTE (recommended levels). Periods of highest catheter-associated urinary tract infection SIRs, hospital-onset Clostridioides difficile and carbapenem-resistant Enterobacteriaceae infection rates, along with 4 of 5 types of surgical site SIRs coincided with the periods of lowest IP staffing levels and the absence of certified IPs and a healthcare epidemiologist. Central-line–associated bloodstream infections increased amid lower nursing levels despite the increased presence of an IP and a hospital epidemiologist. Conclusions: Of 10 HAIs, 8 had highest incidences during periods of lowest IP staffing and experience. Some HAI rates varied inversely with levels of IP staffing and experience and others appeared to be more influenced by nursing levels or other confounders.

AbstractIn the past several decades, the incidence of Klebsiella pneumoniae harboring resistance mechanisms against multiple antibiotic agents has increased on a global scale. We discuss reasons for ongoing transmission of multidrug-resistant K. pneumoniae in healthcare settings, which has resulted in the successful spread and establishment of this pathogen. It is now one of the most important causes of healthcare-associated infections worldwide.

Relevance. Klebsiella pneumoniae is a major cause of severe healthcare-associated infections in children, representing one of the six most widespread multidrug-resistant microorganisms worldwide and requiring the implementation of population-wide treatment strategies.Aim. To study the risk factors for Klebsiella spread in pediatric healthcare settings.Materials and Methods. Here we performed a descriptive retrospective epidemiological study of Klebsiella spp. cases in pediatric units across the entire Kemerovo region (2012–2019). In total, we documented 27,852 treatment outcomes. We further selected 52 confirmed cases and assessed their risk profiles in comparison with 738 condition-matched control children.Results. Average incidence of Klebsiella spp. detection in pediatric healthcare settings was 78.52 per 1,000 patients (95% CI = 75.42–81.74). We revealed a declining incidence of Klebsiella pneumoniae infection in the region, with notable 4-year cyclicity. The proportion of Klebsiella pneumoniae-infected patients increased 2-fold after 5 days of antibiotic therapy. Among the risk factors of Klebsiella pneumonia infection were artificial feeding (OR = 9,21, 95% = 3,31–35,45, р = 0,0001), assisted ventilation (OR = 7,36, 95% CI = 3,92–14,0], р = 0,0001), use of nebulizers (OR = 5,34, 95% CI =2,49 – 10,9], р=0,0001), airway management (OR = 4,62, 95% CI =2,49–8,56, р = 0,0001), preterm birth (OR = 2,55, 95% CI =1,38 – 4,69, р=0,001), low body weight (OR = 2,48, 95% CI = 1,34–4,56, р = 0,002), enema administration (OR = 1,80, 95% CI = 0,78–3,81, р = 0,088), and nasogastric intubation (OR = 1,79, 95% CI = 0,85–3,54, р = 0,065).Conclusions. The incidence of Klebsiella pneumoniae infections is currently lowering and has 4-year cyclicity. Antimicrobial treatment is associated with 2-fold increased risk if administered for ≥ 5 days. A number of healthcare-associated risk factors of Klebsiella pneumoniae infections have been found.

Objective: To verify the effects of comprehensive infection prevention and control (IPC) interventions for the prevention of the cross-transmission of carbapenem-resistant Klebsiella pneumoniae (CRKP) within intensive care units (ICUs) in an epidemic region.Methods: A historical control, quasi-experimental design was performed. The study was conducted between January 2017 and December 2019, following the implementation of a multimodal IPC bundle. The baseline period was established from January 2013 to June 2013, when only basic IPC measures were applied.Results: A total of 748 patients were enrolled during the entire study. The incidence of ICU-acquired CRKP colonization/infection was 1.16 per 1,000 patient-days during the intervention period, compared with 10.19 per 1,000 patient-days during the baseline period (p = 0.002). The slope of the monthly incidence of CRKP at admission showed an increasing trend (p = 0.03). The incidence of ICU-acquired catheter-related bloodstream infections caused by CRKP decreased from 2.54 to 0.96 per 1,000 central-line-days (p = 0.08). Compliance with contact precautions and terminal room disinfection improved during the intervention period. All environmental surface culture samples acquired after terminal room disinfection were negative for CRKP.Conclusion: Our findings suggest that in epidemic settings, multimodal IPC intervention strategies and consistent monitoring of compliance, may limit the spread of CRKP in ICUs.

Clostridioides difficile and norovirus are common causes of healthcare-associated gastroenteritis and both organisms cause outbreaks in pediatric healthcare settings. The spores are resistant to routine environmental cleaning with detergents and can survive in the environment for months. C. difficile can easily be transmitted on the hands of healthcare workers, either from direct patient care activities or through contact with a contaminated environment. Norovirus is highly contagious, with an estimated infectious dose as low as 18 viral particles. Transmission occurs either person-to-person or through ingestion of contaminated food and water. This chapter outlines strategies to prevent transmission of healthcare-associated C. difficile and norovirus infections. It includes recommendations for surveillance, isolation, hand hygiene, environmental cleaning and removal of isolation precautions. Diagnostic methods are reviewed, highlighting the challenge of distinguishing between colonization and clinically significant C. difficile infection in young children.

Carbapenem-resistant Klebsiella pneumoniae is emerging as a significant healthcare-associated pathogen. Clinical cultures detect only a fraction of the colonized population, and patients with asymptomatic colonization are at risk of invasive infection. Additional study of the impact of detection of asymptomatic colonization on subsequent infection and transmission is needed.

Background:Clostridioides difficile is a leading cause of healthcare-associated infections, and greater healthcare exposure is a primary risk factor for Clostridioides difficile infection (CDI). Longer hospital stays and greater CDI pressure, both at the hospital level and the level, have been linked to greater risk. In addition, symptoms associated with healthcare-associated CDI often do not present until a patient has been discharged. Our study objective was to estimate the extent to which exposure to different types of healthcare settings (eg, prior hospitalization, emergency department [ED], outpatient or long-term care) increase risk for hospital-onset CDI. Methods: We conducted a case-control study using the Truven Marketscan Commerical Claims and Medicare Supplemental databases from 2001 to 2017. Case patients were selected as all inpatient visits with a secondary diagnosis of CDI and no previous CDI diagnosis in the prior 90 days. Controls were selected from all inpatient admissions without any CDI diagnosis during the current admission or prior 90 days. A logistic regression model was used to estimate risk associated with prior healthcare exposure. Indicators were created for prior exposure to different healthcare settings: separate indicators were used to indicate transfer, exposure to that setting in the prior 1–30 days, 31–60 days and 61–90 days. Separate indicators were created for prior hospitalization, ED, outpatient clinic, nursing home or long-term care facilities (LTCFs), psychiatric or substance-abuse facility or other outpatient facility. We also included an indicator for prior exposure to a family member with CDI and prior outpatient antibiotics. Results: Estimates for selected variables (odds ratios) are presented in Table 1. Prior hospitalization, ED visits, outpatient clinics, nursing home and LTCFs were all associated with increased risk of secondary diagnosed CDI. Prior hospitalization and nursing home/LTCF conveyed the greatest risk. In addition, a ‘dose-–response’ relationship occurred for each of these exposure settings, with exposure nearest the admission date having the largest risk. Prior exposure to psychiatric , substance abuse, or other outpatient facilities were not risk factors for CDI. Having a family member with prior CDI and both low-risk and high-risk outpatient antibiotics were associated with increased risk. These factors also exhibited a ‘dose–response’ pattern. Conclusions: Exposure to various healthcare settings significantly increased risk for secondary CDI. Prior healthcare exposures occurring nearest to the point of admission conveyed the greatest risk. These results suggest that many hospital-associated CDI cases attributed to a current hospital stay may actually be acquired from prior healthcare settings.Funding: CDC Modeling Infectious Diseases (MInD) in Healthcare NetworkDisclosures: None
