Carbapenem Resistant Enterobacteriaceae

Abstract Background Klebsiella pneumoniae carbapenemase (KPC) and Verona integron-encoded metallo-β-lactamase (VIM) have been the most commonly identified carbapenemases among carbapenemase-producing carbapenem-resistant Enterobacteriaceae (CP-CRE) in Kentucky since 2013. Understanding the frequency and epidemiology of these CP-CRE can help inform prevention strategies. Methods We reviewed reports of KPC- and VIM-producing CRE from January 2013 through December 2017. CRE became reportable in Kentucky in February 2015 and statewide request to laboratories and healthcare facilities for isolate submission for mechanism testing was made in September 2017. Prior to that time, mechanism testing for CRE was conducted at a limited number of laboratories or during outbreak investigations. Demographic data included age, sex, and inpatient or outpatient status. Descriptive analyses were performed. Results As of December 31, 2017, a total of 156 CP-CRE isolates had been identified (124 KPC, 31 VIM, 1 NDM), with an increase from 2013 (n = 13) to 2017 (n = 48). KPC was identified in isolates from 124 patients; VIM was identified in isolates from 26 patients, with 4 patients (15%) having multiple organisms with the mechanism. KPC was identified most commonly from Klebsiella pneumoniae (57/124, 46%); VIM was identified most commonly from Enterobacter cloacae (14/31, 45%). KPC was found in 6 different Enterobacteriaceae genera; VIM in 4. KPC-producing CRE were identified in 22 acute-care and long-term acute-care facilities in 14 counties, with nine reporting >2 isolates. Fifteen percent (19/124) of KPC-producing CRE were isolated from outpatients. VIM-producing CRE were identified in two acute-care facilities located in two urban areas; one was from an outpatient. Patients with VIM were younger than those with KPC (43 vs. 60 years, P < 0.001). Conclusion KPC is the predominant carbapenemase in Kentucky and is more widely disseminated than VIM, which has been limited to two facilities. CRE reporting and mechanism testing have yielded a greater understanding of regional CRE epidemiology and has the potential to facilitate response efforts to slow further spread.

Objective.To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE) in a region with a low incidence of CRE infection.Design.Implementation of the Drug Resistant Organism Prevention and Coordinated Regional Epidemiology (DROP-CRE) Network.Setting and Participants.Oregon infection prevention and microbiology laboratory personnel, including 48 microbiology laboratories, 62 acute care facilities, and 140 long-term care facilities.Methods.The DROP-CRE working group, comprising representatives from academic institutions and public health, convened an interdisciplinary advisory committee to assist with planning and implementation of CRE epidemiology and control efforts. The working group established a statewide CRE definition and surveillance plan; increased the state laboratory capacity to perform the modified Hodge test and polymerase chain reaction for carbapenemases in real time; and administered surveys that assessed the needs and capabilities of Oregon infection prevention and laboratory personnel. Results of these inquiries informed CRE education and the response plan.Results.Of 60 CRE reported from November 2010 through April 2013, only 3 were identified as carbapenemase producers; the cases were not linked, and no secondary transmission was found. Microbiology laboratories, acute care facilities, and long-term care facilities reported lacking carbapenemase testing capability, reliable interfacility communication, and CRE awareness, respectively. Survey findings informed the creation of the Oregon CRE Toolkit, a state-specific CRE guide booklet.Conclusions.A regional epidemiology surveillance and response network has been implemented in Oregon in advance of widespread CRE transmission. Prospective surveillance will determine whether this collaborative approach will be successful at forestalling the emergence of this important healthcare-associated pathogen.

We describe the results of carbapenem-resistant Enterobacteriaceae (CRE) screening as part of an outbreak investigation of New Delhi metallo-β-lactamase–producing CRE at a tertiary care university teaching hospital. The manual method for CRE screening was useful for detecting patients with asymptomatic CRE carriage but was time-consuming and costly.

Abstract Background Multidrug-resistant organisms (MDROs) spread between hospitals, nursing homes (NHs), and long-term acute care facilities (LTACs) via patient transfers. The Shared Healthcare Intervention to Eliminate Life-threatening Dissemination of MDROs in Orange County is a regional public health collaborative involving decolonization at 38 healthcare facilities selected based on their high degree of patient sharing. We report baseline MDRO prevalence in 21 NHs/LTACs. Methods A random sample of 50 adults for 21 NHs/LTACs (18 NHs, 3 LTACs) were screened for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), extended-spectrum β-lactamase–producing organisms (ESBL), and carbapenem-resistant Enterobacteriaceae (CRE) using nares, skin (axilla/groin), and peri-rectal swabs. Facility and resident characteristics associated with MDRO carriage were assessed using multivariable models clustering by person and facility. Results Prevalence of MDROs was 65% in NHs and 80% in LTACs. The most common MDROs in NHs were MRSA (42%) and ESBL (34%); in LTACs they were VRE (55%) and ESBL (38%). CRE prevalence was higher in facilities that manage ventilated LTAC patients and NH residents (8% vs <1%, P < .001). MDRO status was known for 18% of NH residents and 49% of LTAC patients. MDRO-colonized adults commonly harbored additional MDROs (54% MDRO+ NH residents and 62% MDRO+ LTACs patients). History of MRSA (odds ratio [OR] = 1.7; confidence interval [CI]: 1.2, 2.4; P = .004), VRE (OR = 2.1; CI: 1.2, 3.8; P = .01), ESBL (OR = 1.6; CI: 1.1, 2.3; P = .03), and diabetes (OR = 1.3; CI: 1.0, 1.7; P = .03) were associated with any MDRO carriage. Conclusions The majority of NH residents and LTAC patients harbor MDROs. MDRO status is frequently unknown to the facility. The high MDRO prevalence highlights the need for prevention efforts in NHs/LTACs as part of regional efforts to control MDRO spread.

Carbapenem Resistant Enterobacteriaceae

Background.Carbapenem-resistant Enterobacteriaceae (CRE) are clinically challenging, threaten patient safety, and represent an emerging public health issue. CRE reporting is not mandated in Michigan.Methods.The Michigan Department of Community Health–led CRE Surveillance and Prevention Initiative enrolled 21 facilities (17 acute care and 4 long-term acute care facilities) across the state. Baseline data collection began September 1, 2012, and ended February 28, 2013 (duration, 6 months). Enrolled facilities voluntarily reported cases of Klebsiella pneumoniae and Escherichia coli according to the surveillance algorithm. Patient demographic characteristics, laboratory testing, microbiology, clinical, and antimicrobial information were captured via standardized data collection forms. Facilities reported admissions and patient-days each month.Results.One-hundred two cases over 957,220 patient-days were reported, resulting in a crude incidence rate of 1.07 cases per 10,000 patient-days. Eighty-nine case patients had test results positive for K. pneumoniae, whereas 13 had results positive for E. coli. CRE case patients had a mean age of 63 years, and 51% were male. Urine cultures (61%) were the most frequently reported specimen source. Thirty-five percent of cases were hospital onset; sixty-five percent were community onset (CO), although 75% of CO case patients reported healthcare exposure within the previous 90 days. Cardiovascular disease, renal failure, and diabetes mellitus were the most frequently reported comorbid conditions. Common ris k factors included surgery within the previous 90 days, recent infection or colonization with a multidrug-resistant organism, and recent exposures to antimicrobials, especially third- or fourth-generation cephalosporins.Conclusions.CRE are found throughout Michigan healthcare facilities. Implementing a regional, coordinated surveillance and prevention initiative may prevent CRE from becoming hyperendemic in Michigan.

Infections caused by carbapenem-resistant Enterobacteriaceae, especially carbapenemase producing Klebsiella pneumoniae, represent an urgent threat as outlined by the Centers for Disease Control and Prevention (CDC). We present a 66-year-old male with spinal stenosis who underwent elective L2-pelvis posterior spinal fusion at an outside institution and rapidly developed a complicated infection with Klebsiella pneumoniae harboring Klebsiella pneumoniae carbapenemase. This is the first described case of a patient with Klebsiella pneumoniae harboring Klebsiella pneumoniae carbapenemase causing postoperative lumbar wound infection and bacteremia, successfully treated with ceftazidime-avibactam in combination with additional synergistic antibacterials and without hardware removal.
