Background: Carbapenem-resistant Acinetobacter baumannii (CRAB), a multidrug-resistant gram-negative bacterium, can cause difficult-to-treat infections with mortality in approximately half of CRAB cases. CRAB can spread among healthcare facilities after transfer of an infected or colonized patient. Strategies to limit CRAB spread include adherence to contact precautions, environmental cleaning with bleach, and screening to identify colonized patients. During July–September 2018, the Connecticut Department of Public Health (DPH) worked with an acute-care hospital (hospital A) to contain an outbreak of OXA-23–producing CRAB (OXA-23 is an enzyme that confers resistance to carbapenems). During November 2018–March 2019, statewide CRAB surveillance identified additional cases of related OXA-23–producing CRAB at other healthcare facilities. DPH, Connecticut State Public Health Laboratory (SPHL), and the Antibiotic Resistance Laboratory Network (ARLN) investigated to prevent additional cases. Methods: Since January 2017, CRAB isolates have been routinely sent to SPHL and ARLN for carbapenemase gene detection and whole-genome sequencing (WGS) to determine isolate relatedness. During November 2018–March 2019, DPH collected patient healthcare history for patients with CRAB isolates to identify outbreaks and provide assistance in infection control and prevention to healthcare facilities reporting CRAB cases. Beginning May 2019, DPH and ARLN offered facilities screening to identify patients colonized with OXA-23–producing CRAB. Results: Of 10 OXA-23–producing CRAB isolates reported to DPH during November 2018–March 2019, 3 were closely related to the 9 isolates from hospital A’s outbreak by WGS (single-nucleotide polymorphism difference range, 1–16). One isolate was from a patient who had been admitted to hospital A during July 2018. All 3 patients with CRAB isolates shared a history of residence at long-term–care facility A (LTCF A). Two patients received a CRAB infection diagnosis upon admission to hospital B after transfer from LTCF A. Both LTCF A and hospital B performed environmental cleaning with bleach and placed CRAB-identified patients on contact precautions. LTCF A declined screening patients for CRAB, whereas hospitals B and C, which receive frequent transfers from LTCF A, screened all patients on admission from LTCF A. During May–September 2019, among 6 patients screened, 1 was colonized with OXA-23–producing CRAB and was placed on contact precautions. Conclusions: Transfer of patients who are infected or colonized with CRAB among hospitals and LTCFs can facilitate the regional spread of CRAB. Strategies for containing the spread of carbapenemase-producing organisms include adherence to contact precautions, colonization screening, interfacility communication, and collaboration with public health.Funding: NoneDisclosures: None

The emergence of infections (and colonization) with Enterobacteriaceae-producing carbapenemases is a threatening public health problem. In the last decades, we watched an isolated case becoming a brutal outbreak, a sporadic description becoming an endemic problem. The present study aims to highlight the dissemination of IMP-22-producing Klebsiella pneumoniae in the North of Portugal, through the phenotypic and genotypic characterization of isolates collected from hospitalized patients (n=5) and out-patients of the emergency ward of the same acute care hospital (n=2), and isolates responsible for the intestinal colonization of residents in a Long-Term Care Facility (n=4). Pulsed-field gel electrophoresis (PFGE) results, associated with conjugation experiments pointed to a pattern of both vertical and horizontal dissemination. Overall, and complementing other studies that give relevance to IMP-22-producing K. pneumoniae in the clinical settings, here we show for the first time the public health threatening breach of the hospital frontier of this resistance threat, toward the community.

Carbapenem Resistant Enterobacteriaceae

Abstract Background A global rise in carbapenem-resistant Enterobacteriaceae (CRE) has been noted over the past two decades. State and local data on CRE are necessary to better inform public health interventions. Methods Reporting of CRE (i.e., Enterobacteriaceae resistant to any carbapenem or shown to produce a carbapenemase) was mandated in Kentucky in 2015. Voluntary submission of isolates to the Antibiotic Resistance Laboratory Network regional laboratory for carbapenemase testing began September 2017. Demographic data collected as part of reporting included age, sex, county of residence, and inpatient/outpatient status. Descriptive and chi-square analyses were performed. Results Between September 1, 2017 and February 28, 2018, 149 CRE were reported to the Kentucky Department for Public Health. Testing for presence of a carbapenemase was performed on 115 isolates (77.2%); 44 (38.3%) were carbapenemase producing (CP)-CRE and Klebsiella pneumoniae carbapenemase (KPC) was identified from 38 (86.4%). Also identified were Verona integron-encoded metallo-β-lactamase (VIM; 5, 11.4%) and New Delhi metallo-β-lactamase (NDM; 1, 2.3%). Identification of carbapenemase varied among genera: Citrobacter (3/4, 75%), Klebsiella (21/40, 52.5%), Serratia (2/5, 40%), Escherichia (6/20, 30%), Enterobacter (11/41, 26.8%), Proteus (0/4, 0%), other genera (1/2, 50%). CRE isolates from urban or suburban areas were more likely CP-CRE than were those from rural areas (30/65, 46.2% vs. 14/50, 28%, P = 0.047). Carbapenemase was identified more often among CRE isolates from currently hospitalized patients than from patients whose cultures were collected outside of an acute care hospital (37/70, 52.8% vs. 7/45, 15.6%; P < 0.001). Conclusion The percentage of CRE that were CP-CRE in Kentucky was comparable with that reported for the United States (38 vs. 32%). Klebsiella spp., the genera historically associated with CP-CRE, made up less than half of CP-CRE. CP isolates were identified from urban, suburban, and rural settings and more frequently from isolates collected in hospitals compared with the community. The additional epidemiology obtained as part of this reporting system has identified metropolitan areas of the state as targets for CRE prevention efforts.

The Impact

ABSTRACTHospital and long-term care facility utilization, mortality and functional status over a 12-month follow-up period are described for elderly home care recipients who had been discharged from an acute care hospital. Of those eligible for receipt of services from the Program, 356 (92%) patients 65 years of age and older agreed to participate in the study at the time of discharge from an acute care hospital. Of these, 82.2 per cent survived during the subsequent 12 months, 44 per cent were readmitted to hospital, and 5 per cent were admitted to a nursing home or home for the aged. After adjusting for socio-demographic and health variables using regression analyses, the total number of home care services received was significantly associated with physical function and social function at 12 months. Similarly, the analyses revealed home care “social services” (social worker visits, meals on wheels, visiting home maker visits and volunteer visits) received were significantly associated with morale at 12 months. The clinical significance of these findings for case-management and home care program management and monitoring are discussed.

Background.Controversy exists over whetherClostridium difficileinfection (CDI) commonly occurs in long-term care facility residents who have not been recently transferred from an acute care hospital.Objective.To assess the incidence and outcome of CDI in a long-term care facility.Methods.Retrospective cohort study in a 262-bed long-term care Veterans Affairs facility in Pittsburgh, Pennsylvania, for the period January 2004 through June 2010. CDI was identified by positive stoolC. difficiletoxin assay and acute diarrhea. Patients were categorized as hospital-associated CDI (HACDI) or long-term care facility–associated CDI (LACDI) and followed for 6 months.Results.The annual rate of CDI varied between 0.11 and 0.23 per 1,000 resident-days for HACDI patients and between 0.04 and 0.28 per 1,000 resident-days for LACDI patients. We identified 162 patients, 96 patients (59.3%) with HACDI and 66 patients (40.7%) with LACDI. Median age was 74 and 77 years, respectively, for HACDI and LACDI (P= .055) patients. There were more patients with at least 1 relapse of CDI during 6 months of follow up in LACDI patients (32/66, 48.5%) than in HACDI patients (28/96, 29.2%;P= .009). Logistic regression showed that ages of at least 75 years (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.07–5.07;P= .033), more than 2 transfers to an acute care hospital (OR, 7.88; 95% CI, 1.88–32.95;P= .005), and LACDI (OR, 3.15; 95% CI, 1.41–7.05;P= .005) were associated with relapse of CDI.Conclusions.Forty percent of CDI cases were acquired within the long-term care facility, indicating a substantial degree of transmission. Optimal strategies to prevent CDI in the long-term care facility are needed.

Objective.To describe a Klebsiella pneumoniae carbapenemase (KPC)–producing carbapenem-resistant Enterobacteriaceae (CRE) outbreak and interventions to prevent transmission.Design, Setting, and Patients.Epidemiologic investigation of a CRE outbreak among patients at a long-term acute care hospital (LTACH).Methods.Microbiology records at LTACH A from March 2009 through February 2011 were reviewed to identify CRE transmission cases and cases admitted with CRE. CRE bacteremia episodes were identified during March 2009–July 2011. Biweekly CRE prevalence surveys were conducted during July 2010–July 2011, and interventions to prevent transmission were implemented, including education and auditin? of staff and isolation and cohorting of CRE patients with dedicated nursing staff and shared medical equipment. Trends were evaluated using weighted linear or Poisson regression. CRE transmission cases were included in a case-control study to evaluate risk factors for acquisition. A real-time polymerase chain reaction assay was used to detect the blaKPC gene, and pulsed-field gel electrophoresis was performed to assess the genetic relatedness of isolates.Results.Ninety-nine CRE transmission cases, 16 admission cases (from 7 acute care hospitals), and 29 CRE bacteremia episodes were identified. Significant reductions were observed in CRE prevalence (49% vs 8%), percentage of patients screened with newly detected CRE (44% vs 0%), and CRE bacteremia episodes (2.5 vs 0.0 per 1,000 patient-days). Cases were more likely to have received β-lactams, have diabetes, and require mechanical ventilation. All tested isolates were KPC-producing K. pneumoniae, and nearly all isolates were genetically related.Conclusion.CRE transmission can be reduced in LTACHs through surveillance testing and targeted interventions. Sustainable reductions within and across healthcare facilities may require a regional public health approach.Infect Control Hosp Epidemiol 2012;33(10):984-992

Carbapenem Resistant Enterobacteriaceae

Background: Carbapenem-resistant Enterobacteriaceae (CRE), particularly carbapenemase-producing (CP) CRE, pose a major public health threat. In 2016, the phenotypic definition of CRE expanded to include ertapenem resistance to improve sensitivity for detecting CP-CRE. We compared characteristics of CRE resistant to ertapenem only (CRE-EO) to CRE resistant to ≥1 other carbapenem (CRE-O). Methods: The Georgia Emerging Infections Program performs active, population-based CRE surveillance in metropolitan Atlanta. CRE cases were defined as any Escherichia coli, Klebsiella pneumoniae, K. oxytoca, K. variicola, Enterobacter cloacae complex, or Enterobacter aerogenes resistant to ≥1 carbapenem by the clinical laboratory and isolated from urine or a sterile site between 2016 and 2018. Data were extracted from retrospective chart review and 90-day mortality from Georgia vital statistics for 2016–2017. Polymerase chain reaction (PCR) for carbapenemase genes was performed on a convenience sample of isolates by the CDC or Georgia Public Health Laboratory. We compared characteristics of CRE-EO cases to CRE-O cases using χ2 tests or t tests. Results: Among 927 CRE isolates, 553 (60%) were CRE-EO. CRE-EO were less frequently isolated from blood (5% vs 12%; P < .01) and less commonly K. pneumoniae (21% vs 58%; P < .01) than CRE-O. CRE-EO cases were more often women (65% vs 50%; P < .01), had a lower Charlson comorbidity index (mean ± SD, 2.4±2.3 vs 3.0±2.6; P < .01), and were less commonly at a long-term care facility (24% vs 31%) or hospital (15% vs 21%; P < .01) in the 4 days prior to the CRE culture. CRE-EO were more susceptible to all antibiotics tested at the clinical laboratory (P < .01) except for tigecycline (P = 1.0) (Table 1). Of the 300 (32%) isolates tested for carbapenemase genes, 98 (33%) were positive (7% CRE-EO vs 62% CRE-O; P < .01). Of the CP isolates, we identified blaKPC in 93 cases (95%), blaNDM in 3 cases (3%), blaOXA-48-like in 2 cases (2%). CRE-EO cases had lower 90-day mortality (13% vs 21%; P < .01). Conclusions: CRE-EO are epidemiologically distinct from CRE-O and are less likely to harbor carbapenemase genes. CRE-EO may require less intensive infection prevention interventions and have more therapeutic options.Funding: NoneDisclosures: None

Background: Contaminated healthcare facility plumbing is increasingly recognized as a source of carbapenemase-producing organisms (CPOs). In August 2019, the Tennessee State Public Health Laboratory identified Tennessee’s twelfth VIM-producing carbapenem-resistant Pseudomonas aeruginosa (VIM-CRPA), from a patient in a long-term acute-care hospital. To determine a potential reservoir, the Tennessee Department of Health (TDH) reviewed healthcare exposures for all cases. Four cases (33%), including the most recent case and earliest from March 2018, had a history of admission to intensive care unit (ICU) room X at acute-care hospital A (ACH A), but the specimens were collected at other facilities. The Public Health Laboratory collaborated with ACH A to assess exposures, perform environmental sampling, and implement control measures. Methods: TDH conducted in-person infection prevention assessments with ACH A, including a review of the water management program. Initial recommendations included placing all patients admitted to room X on contact precautions, screening for CPO on room discharge, daily sink basin and counter cleaning, and other sink hygiene measures. TDH collected environmental and water samples from 5 ICU sinks (ie, the handwashing and bathroom sinks in room X and neighboring room Y [control] and 1 hallway sink) and assessed the presence of VIM-CRPA. Moreover, 5 patients and 4 environmental VIM-CRPA underwent whole-genome sequencing (WGS). Results: From February to June 2020, of 21 patients admitted to room X, 9 (43%) underwent discharge screening and 4 (44%) were colonized with VIM-CRPA. Average room X length of stay was longer for colonized patients (11.3 vs 4.8 days). Drain swabs from room X’s bathroom and handwashing sinks grew VIM-CRPA; VIM-CRPA was not detected in tap water or other swab samples. VIM-CRPA from the environment and patients were sequence type 253 and varied by 0–13 single-nucleotide variants. ACH A replaced room X’s sinks and external plumbing in July. Discharge screening and contact precautions for all patients were discontinued in November, 5 months following the last case and 12 consecutive negative patient discharge screens. Improved sink hygiene and mechanism testing for CRPA from clinical cultures continued, with no new cases identified. Conclusions: An ICU room with a persistently contaminated sink drain was a persistent reservoir of VIM-CRPA. The room X attack rate was high, with VIM-CRPA acquisition occurring in >40% of patients screened. The use of contaminated plumbing fixtures in ACH have the potential to facilitate transmission to patients but may be challenging to identify and remediate. All healthcare facilities should follow sink hygiene best practices.Funding: NoDisclosures: None

Background: Cleanliness of hospital surfaces helps prevent healthcare-associated infections, but larger evaluations of the effectiveness of various cleaning strategies during SARS-CoV-2 surges and worker shortages are scarce. Methods: In an acute care hospital (ACH) and a long-term care facility (LTCF), 417 surfaces were tested for SARS-CoV-2 and adenosine triphosphate before and after various cleaning strategies, including ultraviolet light (UV-C), electrostatic spraying, and room fogging. Results: ACH surface contamination differed among outbreak and non-outbreak wards (p = 0.001). RNA was detected on 66% of surfaces before cleaning and on 23% of those surfaces immediately after terminal cleaning, for a 65% post-cleaning reduction (p = 0.001). UV-C resulted in an 87% reduction (p = 0.023), while spraying with electrostatic bleach resulted in a 47% reduction (p = 0.010). LTCF contamination rates differed between the dementia, rehabilitation, and the residential units (p = 0.005). 67% of surfaces had RNA after room fogging without terminal-style wiping. Fogging with wiping led to an 11% reduction in the proportion of positive surfaces. Discussion: Baseline contamination varied by type of unit and outbreak conditions, but not facility type. Removal of viral RNA varied according to strategy. Unlike previous reports, time spent cleaning was associated with cleaning thoroughness.
