Objective.To assess definitions, experience, and infection control practices for multidrug-resistant gram-negative bacteria (MDR-GNB), including Enterobacteriaceae, Acinetobacter, and Pseudomonas species, in acute care hospitals.Design.Cross-sectional survey.Participants.US and international members of the Society for Healthcare Epidemiology of America (SHEA) Research Network.Methods.Online survey that included definitions, infection control procedures, and microbiology capability related to MDR-GNB and other MDR bacteria.Results.From November 2012 through February 2013, 66 of 170 SHEA Research Network members responded (39% response rate), representing 26 states and 15 countries. More than 80% of facilities reported experience with each MDR-GNB isolate, and 78% had encountered GNB resistant to all antibiotics except colistin (62% Acinetobacter, 59% Pseudomonas, and 52% Enterobacteriaceae species). Participants varied regarding their definitions of “multidrug resistant,” with 14 unique definitions for Acinetobacter, 18 for Pseudomonas, and 22 for Enterobacteriaceae species. Substantial variation also existed in isolation practices. Although isolation was commonly used for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and carbapenem-resistant Enterobacteriaceae (CRE), approximately 20% of facilities did not isolate for MDR Pseudomonas or Acinetobacter. The majority of those that isolated MDR organisms also removed isolation using a wide variety of criteria.Conclusion.Facilities vary significantly in their approach to preventing MDR-GNB transmission. Although practices for MRSA and VRE are relatively standardized, emerging pathogens CRE and other MDR-GNB have highly varied definitions and management. This confusion makes communication difficult, and varied use of isolation may contribute to emergence of these organisms. Public health agencies need to promote standard definitions and management to enable broader initiatives to limit emergence of MDR-GNB.

Abstract Objective: To describe interfacility transfer communication (IFTC) methods for notification of multidrug-resistant organism (MDRO) status in a diverse sample of acute-care hospitals. Design: Cross-sectional survey. Participants: Hospitals within the Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN). Methods: SRN members completed an electronic survey on protocols and methods for IFTC. We assessed differences in IFTC frequency, barriers, and perceived benefit by presence of an IFTC protocol. Results: Among 136 hospital representatives who were sent the survey, 54 (40%) responded, of whom 72% reported having an IFTC protocol in place. The presence of a protocol did not differ significantly by hospital size, academic affiliation, or international status. Of those with IFTC protocols, 44% reported consistent notification of MDRO status (>75% of the time) to receiving facilities, as opposed to 13% from those with no IFTC protocol (P = .04). Respondents from hospitals with IFTC protocols reported significantly fewer barriers to communication compared to those without (2.8 vs 4.3; P = .03). Overall, however, most respondents (56%) reported a lack of standardization in communication. Presence of an IFTC protocol did not affect whether respondents perceived IFTC protocols as having a significant impact on infection prevention or antimicrobial stewardship. Conclusions: Most respondents reported having an IFTC protocol, which was associated with reduced communication barriers at transfer. Standardization of protocols and clarity about expectations for sending and receipt of information related to MDRO status may facilitate IFTC and promote appropriate and timely infection prevention practices.

AbstractHealthcare-associated infections (HAI) are an important public health threat with the multidrug-resistant (MDR) gram-negative bacteria (GNB) being of particular concern. Here we present the antimicrobial resistance profile of HAI-related GNB (HAIrB) isolated from patients (PT), healthcare workers (HCW) and hospital environment (HE) in a six-month screening program. From the 180 sampling points distributed in six hospital units, a total of 1,080 swabs were collected allowing the isolation of 390 HAIrB: 50.5% from HE, 42.6% from PT and 6.9% from HCW. Among the HAIrB, 32.6% were characterized as MDR and 38.7% as extended-spectrum cephalosporins resistant (ESC-R), showing no differences in the distribution between PT, HE and HCW. Carbapenem resistance (CARB-R) was detected for 17.7% of all HAIrB, being higher among Acinetobacter spp. isolates (36.5%), followed by Enterobacteriaceae (14.5%) and Pseudomonas spp. (11.8%). Except for the ICU, that revealed higher MDR, CARB-R and ESC-R rates, HAIrB-resistant profiles were similarly detected within the hospital units. Prevalence of blaKPC-like and blaCTX-M-1 β-lactamases-resistance genes was higher in K. pneumoniae and E. cloacae complex, while blaOXA-23-like and blaSPM-like were higher in A. baumannii and P. aeruginosa, respectively. This study reveals that the spreading of HAIrB within a hospital environment is higher than predicted, indicating that healthcare workers, hospital areas and equipment are key players on dissemination of MDR gram-negative bacteria and shows that an active surveillance program can provide precise understanding and direct actions towards control of HAI.

Background. Diabetic foot infections (DFIs) are a major public health issue and identification of the microorganisms causing such polymicrobial infections is useful to find out appropriate antibiotic therapy. Meanwhile, many reports have shown antibiotic resistance rising dramatically. In the present study, we sought to determine the prevalence of microorganisms detected on culture in complicated DFIs in hospitalized patients and their antibiotic sensitivity profiles.Methods. A cross-sectional study was conducted for a period of 24 months from 2012 to 2014 in Nemazee Hospital, Shiraz, Iran. The demographic and clinical features of the patients were obtained. Antimicrobial susceptibility testing to different agents was carried out using the disc diffusion method.Results. During this period, 122 aerobic microorganisms were isolated from DFIs. Among Gram-positive and Gram-negative bacteria,Staphylococcusspp. andE. coliwere the most frequent organisms isolated, respectively. Of the isolates, 91% were multidrug while 78% ofS. aureusisolates were methicillin resistant. 53% of Gram-negative bacteria were positive for extended-spectrumβ-lactamase.Conclusion. Given the involvement of different microorganisms and emergence of multidrug resistant strains, clinicians are advised to consider culture before initiation of empirical therapy.

Abstract Background Carriage of multidrug resistant (MDR) Gram-negative bacteria (GN) in hospitalized neonates may increase the risk of difficult-to-treat invasive infections at neonatal intensive care units (NICUs). Data on MDRGN carriage among hospitalized newborns in Africa are limited. Methods We conducted a cross-sectional study at the NICUs of 2 tertiary hospitals in Ghana. Swabs from the axilla, groin, perianal region, and the environment were cultured, GN were identified, and antibiotic susceptibility was tested. We obtained blood culture isolates from neonates with sepsis. Whole-genome sequencing was used to characterize carbapenemase-producing Klebsiella pneumoniae. Typing was done by multilocus sequence typing (MLST) and single nucleotide polymorphism (SNP) analysis. Results A total of 276 GN were isolated from 228 screened neonates. Pathogenic GN were cultured in 76.8% (175 of 228) of neonates. Klebsiella spp (41.7%; 115 of 276) and Escherichia coli (26.4%; 73 of 276) were the commonest organisms. Carriage rates of MDRGN and third-generation cephalosporin resistant organisms were 49.6% (113 of 228) and 46.1% (105 of 228), respectively. Among Klebsiella spp, 75.6% (87 of 115) phenotypically expressed extended-spectrum β-lactamase activity, whereas 15.6% expressed carbapenemase and harbored bla-OXA-181 and bla-CTX-M-15. Overall, 7.0% (16 of 228) of neonates developed GN bloodstream infection. In 2 of 11 neonates, sequencing showed the same identity between carriage and the bloodstream isolate. Length of stay before specimen collection and antibiotic use were independently associated with carriage rates, which increased from 13% at admission to 42% by day 2 and reached a plateau at 91% by day 15. Conclusions High carriage rates of MDRGN, including carbapenemase-producing enterobacterales may be an emerging problem in NICUs in Africa.

OBJECTIVECentral line-associated bloodstream infection (CLABSI) is associated with significant morbidity and mortality. Despite a nationwide decline in CLABSI rates, individual hospital success in preventing CLABSI is variable. Difficulty in interpreting and applying complex CLABSI metrics may explain this problem. Therefore, we assessed expert interpretation of CLABSI quality data. DESIGN. Cross-sectional survey PARTICIPANTS. Members of the Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN) METHODS. We administered a 10-item test of CLABSI data comprehension. The primary outcome was percent correct of attempted questions pertaining to the CLABSI data. We also assessed expert perceptions of CLABSI reporting.RESULTSThe response rate was 51% (n=67).Among experts, the average proportion of correct responses was 73% (95% confidence interval [CI], 69%–77%). Expert performance on unadjusted data was significantly better than risk-adjusted data (86% [95% CI, 81%–90%] vs 65% [95% CI, 60%–70%];P<.001). Using a scale of 1 to 100 (0, never reliable; 100, always reliable), experts rated the reliability of CLABSI data as 61. Perceived reliability showed a significant inverse relationship with performance (r=–0.28;P=.03), and as interpretation of data improved, perceptions regarding reliability of those data decreased. Experts identified concerns regarding understanding and applying CLABSI definitions as barriers to care.CONCLUSIONSSignificant variability in the interpretation of CLABSI data exists among experts. This finding is likely related to data complexity, particularly with respect to risk-adjusted data. Improvements appear necessary in data sharing and public policy efforts to account for this complexity.Infect Control Hosp Epidemiol2018;39:71–76

AbstractNew recommendations for infection control in the case of infection or colonization by multidrug-resistant Gram-negative bacteria were published by the Commission for Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute, Germany. In this context, a new definition for multidrug-resistance, the so-called MRGN classification, was introduced. This was necessary because previous definitions did not seem suitable for the purpose of hospital hygiene. The MRGN classification grades multidrug-resistance by severity distinguishing 3MRGN and 4MRGN, resulting in different recommendations for infection control. In addition, not all antibiotics are regarded as equally important in the classification, but only the most relevant classes, such as ureidopenicillins, extended-spectrum cephalosporins, carbapenems, and fluoroquinolones, are taken into account. The MRGN classification is mainly based on resistance categories, not on resistance mechanisms. An exception has been made for carbapenemase-producing
