Carbapenem Resistant Enterobacteriaceae

Background: A carbapenem-resistant Enterobacteriaceae (CRE) outbreak occurred in an advanced emergency medical service center [hereafter referred to as the intensive care unit (ICU)] between 2016 and 2017. Aim: Our objective was to evaluate the infection control measures for CRE outbreaks. Methods: CRE strains were detected in 16 inpatients located at multiple sites. Environmental cultures were performed and CRE strains were detected in 3 of 38 sites tested. Pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), and detection of β-lactamase genes were performed against 25 CRE strains. Findings: Molecular typing showed the PFGE patterns of two of four Klebsiella pneumoniae strains were closely related and the same MLST (ST2388), and four of five Enterobacter cloacae strains were closely related and same MLST (ST252). Twenty-three of 25 CRE strains harbored the IMP-1 β-lactamase gene and 15 of 23 CRE strains possessed IncFIIA replicon regions. Despite interventions by the infection control team, new inpatients with the CRE strain continued to appear. Therefore, the ICU was partially closed and the inpatients with CRE were isolated, and the ICU staff was divided into two groups between inpatients with CRE and non-CRE strains to avoid cross-contamination. Although the occurrence of new cases dissipated quickly after the partial closure, a few months were required to eradicate the CRE outbreak. Conclusion: Our data suggest that the various and combined measures that were used for infection control were essential in stopping this CRE outbreak. In particular, partial closure to isolate the ICU and division of the ICU staff were effective.

Carbapenem Resistant Enterobacteriaceae

Abstract Background The increasing number of carbapenem-resistant Enterobacteriaceae (CRE) has become a serious problem globally. This study aimed to elucidate their geographically epidemiological characteristics and explore evidence-based infection control measures. Results A total of 930 phenotypically confirmed CRE isolates collected from 19 hospitals were genotypically characterised. K.pneumoniae (KP) and E.coli isolates were 787 (85.17%) and 96 (10.39%) among 924 carbapenemase-producing Enterobacteriaceae (CPE) isolates. Two major carbapenemase genes KPC-2 and NDM in CPE isolates accounted for 84.63% (n = 782) and 13.74% (n = 127). ST11 comprised 86.32% (631/731) of KPC-2 KP isolates. Wzi typing could discriminate ST11 KP clones and precisely track their transmission. Conjugation assays demonstrated that Some KPC-2- and NDM-bearing plasmids could be conjugatively transferred. The transferability was influenced by different STs and different wzis. CRE patients were becoming increasingly younger due to nosocomial CRE acquisition. The average length of hospitalization of these patients showed a downward trend mainly due to significant increases in voluntarily discharged rates and mortality rates. No associations between the rates of antibiotics consumption and CRE prevalence were observed. Evidence-based measures could effectively reduce the prevalence of ST11-wzi209 clone but failed to control the dissemination of ST11-wzi141 KP clone. Conclusions Continued vigilance for the importations should be maintained. Coordinated regional interventions are urgently needed to reduce CRE threat.

AbstractWe demonstrated a 20% rate of subsequent carbapenem-resistant Enterobacteriaceae (CRE)–associated infections among hospitalized CRE carriers. Independent factors associated with the infections were number of colonization sites, central-line insertion, and receiving vancomycin before colonization. These findings underscore the importance of antibiotic stewardship and device-related infection control measures to prevent CRE infections.

Abstract Objective: Ventilator-capable skilled nursing facilities (vSNFs) are critical to the epidemiology and control of antibiotic-resistant organisms. During an infection prevention intervention to control carbapenem-resistant Enterobacterales (CRE), we conducted a qualitative study to characterize vSNF healthcare personnel beliefs and experiences regarding infection control measures. Design: A qualitative study involving semistructured interviews. Setting: One vSNF in the Chicago, Illinois, metropolitan region. Participants: The study included 17 healthcare personnel representing management, nursing, and nursing assistants. Methods: We used face-to-face, semistructured interviews to measure healthcare personnel experiences with infection control measures at the midpoint of a 2-year quality improvement project. Results: Healthcare personnel characterized their facility as a home-like environment, yet they recognized that it is a setting where germs were ‘invisible’ and potentially ‘threatening.’ Healthcare personnel described elaborate self-protection measures to avoid acquisition or transfer of germs to their own household. Healthcare personnel were motivated to implement infection control measures to protect residents, but many identified structural barriers such as understaffing and time constraints, and some reported persistent preference for soap and water. Conclusions: Healthcare personnel in vSNFs, from management to frontline staff, understood germ theory and the significance of multidrug-resistant organism transmission. However, their ability to implement infection control measures was hampered by resource limitations and mixed beliefs regarding the effectiveness of infection control measures. Self-protection from acquiring multidrug-resistant organisms was a strong motivator for healthcare personnel both outside and inside the workplace, and it could explain variation in adherence to infection control measures such as a higher hand hygiene adherence after resident care than before resident care.

ObjectivePatients hospitalized in post-acute care hospitals (PACHs) constitute an important reservoir of antimicrobial-resistant bacteria. High carriage prevalence of carbapenem-resistant Enterobacteriaceae (CRE) has been observed among patients hospitalized in PACHs. The objective of the study is to describe the impact of a national infection control intervention on the prevalence of CRE in PACHs.DesignA prospective cohort interventional study.SettingThirteen PACHs in Israel.InterventionA multifaceted intervention was initiated between 2008 and 2011 as part of a national program involving all Israeli healthcare facilities. The intervention has included (1) periodic on-site assessments of infection control policies and resources, using a score comprised of 16 elements; (2) assessment of risk factors for CRE colonization; (3) development of national guidelines for CRE control in PACHs involving active surveillance and contact isolation of carriers; and (4) 3 cross-sectional surveys of rectal carriage of CRE that were conducted in representative wards.ResultsThe infection control score increased from 6.8 to 14.0 (P < .001) over the course of the study period. A total of 3,516 patients were screened in the 3 surveys. Prevalence of carriage among those not known to be carriers decreased from 12.1% to 7.9% (P = .008). Overall carrier prevalence decreased from 16.8% to 12.5% (P = .013). Availability of alcohol-based hand rub, appropriate use of gloves, and a policy of CRE surveillance at admission to the hospital were independently associated with lower new carrier prevalence.ConclusionA nationwide infection control intervention was associated with enhanced infection control measures and a reduction in the prevalence of CRE in PACHs.

Abstract Background Co-infections of Candida auris and carbapenemase-producing carbapenem-resistant Gram-negative organisms (CP-CRO) are an increasing global concern and rarely seen in the United States. We report the case of a 59-year-old male, with recent hospitalization in India, admitted to our facility with C. auris isolated from urine and axilla/groin specimens and CP-CRO from five body sites. Methods Travel screening in the emergency department identified a patient at high risk for colonization/infection with multidrug-resistant organisms (MDRO). Contact precautions were initiated. Eight CP-CRO isolates were subsequently identified from clinical and routine surveillance cultures from five separate sites. Of the isolates, seven contained one or more carbapenemase-producing genes detected by Xpert Carba-R assay (Cepheid, Sunnyvale, CA) (Table 1). The microbiology laboratory alerted the infection control department of a presumptive positive C. auris from a clinical urine culture from the same patient. Enhanced mitigation strategies were initiated in regards to cleaning and disinfection. An exposure investigation was also conducted using a point prevalence approach. Surveillance cultures were obtained from inpatients currently admitted to the same unit as the index patient. Axilla/groin specimens were collected for C. auris testing, and rectal specimens were collected for CP-CRO gene testing (CRE Real-Time PCR). Results Eighteen patients in addition to the index patient were hospitalized on the acute medicine unit. One patient refused testing for CP-CRO; therefore, 17 patients were tested for CP-CRO, and 18 patients were tested for C. auris. Neither CP-CRO nor C. auris were recovered from any patient. Conclusion A patient co-infected with C. auris and multiple CP-CRO was identified by clinical and routine surveillance cultures at Johns Hopkins Hospital. Travel screening allowed proactive isolation upon presentation. Enhanced infection control measures were implemented and a point prevalence surveillance study was conducted on the general acute care medicine inpatient unit. No transmission of either C. auris or CP-CRO was detected, likely due in part to rapid identification and strict infection control measures. Disclosures All authors: No reported disclosures.

The Italian burden of disease associated with infections due to antibiotic-resistant bacteria has been very high, largely attributed to Carbapenem-Resistant Klebsiella pneumoniae (CR-Kp). The implementation of infection control measures and antimicrobial stewardship programs (ASP) has been shown to reduce healthcare-related infections caused by multidrug resistance (MDR) germs. Since 2016, in our teaching hospital of Terni, an ASP has been implemented in an intensive care unit (ICU) setting, with the “daily-ICU round strategy” and particular attention to infection control measures. We performed active surveillance for search patients colonized by Carbapenem-Resistant Enterobacteriaceae (CRE). In March 2020, coronavirus disease 2019 (COVID-19) arrived and the same ICU was reserved only for COVID-19 patients. In our retrospective observational study, we analyzed the bimonthly incidence of CRE colonization patients and the incidence of CRE acquisition in our ICU during the period of January 2019 to June 2020. In consideration of the great attention and training of all staff on infection control measures in the COVID-19 era, we would have expected a clear reduction in CRE acquisition, but this did not happen. In fact, the incidence of CRE acquisition went from 6.7% in 2019 to 50% in March–April 2020. We noted that 67% of patients that had been changed in posture with prone position were colonized by CRE, while only 37% of patients that had not been changed in posture were colonized by CRE. In our opinion, the high intensity of care, the prone position requiring 4–5 healthcare workers (HCWs), equipped with personal protective equipment (PPE) in a high risk area, with extended and prolonged contact with the patient, and the presence of 32 new HCWs from other departments and without work experience in the ICU setting, contributed to the spread of CR-Kp in our ICU, determining an increase in CRE acquisition colonization.

AbstractTo the best of our knowledge, here, we describe the first hospital-wide outbreak of SARS-CoV-2 that occurred in Germany in April 2020. We aim to share our experience in order to facilitate the management of nosocomial COVID-19 outbreaks in healthcare facilities. All patients and hospital workers were screened for SARS-CoV-2 repeatedly. An infection control team on the side was installed. Strict spatial separation of patients and intensified hygiene training of healthcare workers (HCW) were initiated. By the time of reporting, 26 patients and 21 hospital workers were infected with a cluster of cases in the geriatric department. Fourteen patients developed COVID-19 consistent symptoms and five patients with severe pre-existing medical conditions died. The outbreak was successfully contained after intensified infection control measures were implemented and no further cases among patients were detected over a period of 14 days. Strict application of standard infection control measures proved to be successful in the management of nosocomial SARS-CoV-2 outbreaks.

Crude Mortality

The incidence of carbapenem-resistantEnterobacteriaceae(CRE) has increased worldwide with great regional variability. Infections caused by these organisms are associated with crude mortality rates of up to 70%. The spread of CRE in healthcare settings is both an important medical problem and a major global public health threat. All countries are at risk of falling victim to the emergence of CRE; therefore, a preparedness plan is required to avoid the catastrophic natural course of this epidemic. Proactive and adequate preventive measures locally, regionally, and nationally are required to contain the spread of these bacteria. The keys to success in preventing the establishment of CRE endemicity in a region are early detection through targeted laboratory protocols and containment of spread through comprehensive infection control measures. This guideline provides a strategic roadmap for infection control measures based on the best available evidence and expert opinion, to enable preparation of a multifaceted preparedness plan to abort epidemics of CRE.Infect Control Hosp Epidemiol2017;38:580–594

Background.Nosocomial outbreaks of norovirus infection pose a great challenge to the infection control team.Methods.Between November 1, 2009, and February 28, 2010, strategic infection control measures were implemented in a hospital network. In addition to timely staff education and promotion of directly observed hand hygiene, reverse-transcription polymerase chain reaction for norovirus was performed as an added test by the microbiology laboratory for all fecal specimens irrespective of the request for testing. Laboratory-confirmed cases were followed up by the infection control team for timely intervention. The incidence of hospital-acquired norovirus infection per 1,000 potentially infectious patient-days was compared with the corresponding period in the preceding 12 months, and the incidence in the other 6 hospital networks in Hong Kong was chosen as the concurrent control. Phylogenetic analysis of norovirus isolates was performed.Results.Of the 988 patients who were tested, 242 (25%) were positive for norovirus; 114 (47%) of those 242 patients had norovirus detected by our added test. Compared with the corresponding period in the preceding 12 months, the incidence of hospital-acquired norovirus infection decreased from 131 to 16 cases per 1,000 potentially infectious patient-days (P < .001 ), although the number of hospital-acquired infections was low in both the study period (n = 8) and the historical control periods (n = 11). The incidence of hospital-acquired norovirus infection in our hospital network (0.03 cases per 1,000 patient-days) was significantly lower than that of the concurrent control (0.06 cases per 1,000 patient-days) (P = .015). Forty-three (93%) of 46 norovirus isolates sequenced belonged to the genogroup II.4 variant.Conclusions.Strategic infection control measures with an added test maybe useful in controlling nosocomial transmission of norovirus.
