Background: Elizabethkingia meningoseptica is frequently found in hospital environments and usually associated with healthcare-associated infections (HAIs), particularly in patients in the intensive care units (ICU). The current study report an outbreak of E. meningoseptica infection/colonization in the pediatric intensive care unit, highlighted the infection control methods used to stem the spread.Methods: During a period of 7 months, May-November 2015, 4 patients were infected/ colonized by E. meningoseptica. Infection control measures were re-emphasized after each case and environmental swabs were cultured to detect possible source. Follow up for 25 months to ensure eradication of the pathogen.Results: Four patients were colonized/ infected with E. meningoseptica, their mean age 22 months. The average time patients spent in ICU between admission and isolation of E. meningoseptica was 27.5±19.2 days. All patients were mechanically ventilated. 25% E. meningoseptica isolated from blood causing healthcare associated Central Line Associated Blood Stream Infection (CLABSI) while it was isolated from endotracheal tube (ETT) secretion in 75% as healthcare associated colonization. The 4 isolates confirmed as identical using pulsed field gel electrophoresis (PFGE).Conclusions: Intensive infection control measures including healthcare workers education, emphasizing hand hygiene, comprehensive cleaning and disinfection of equipment and the environment are important to eradicate the bacterium.

Active Surveillance Program

Abstract Background: Antimicrobial resistance in Neonatal Intensive Care Unit (NICU) patients is a threat, due to the large use of antimicrobial treatment and invasive devices in fragile babies.Since 2014 an active surveillance program of multidrug-resistant Gram-negative bacteria (MDR-GNB) carriage is in place in the five NICUs of Palermo, Italy. In 2017 an increase in the prevalence of MDR-GNB and in particular of extended-spectrum β-lactamases-producing Klebsiella pneumoniae (ESBL-KP) was observed in “Civico” hospital NICU.Aim: To estimate the impact of a coordinated intervention strategy in achieving long-lasting reduction of MDR-GNB prevalence in the NICU.Methods: Rectal swabs were obtained monthly and processed to detect MDR-GNB using standard methods. MDR-GNB were characterized by pulsed-field gel electrophoresis (PFGE). From November 2017 the following intervention measures were applied: a) two-months strengthening of sample collection; b) stakeholders’ meetings; c) improvement of prevention measures and antimicrobial policy.Findings: During the strengthened microbiological surveillance MDR-GNB and ESBL-KP were detected in rectal swabs (34.8%; 23.2%), nasal swabs (24.6%; 14.5%), oral swabs (14.5%; 5.4%), milk samples (32.1%; 17.9%), soother swabs (30.8%; 17.9%) and from a sub-intensive room surface. Thirteen ESBL-KP strains isolated from clinical and environmental samples showed identical PFGE patterns.Prevalence of MDR-GNB and ESBL-KP carriage significantly decreased in the year after intervention compared to the previous year (20.6% vs 62.2 %; p<0.001 and 11.1% vs 57.8%; p<0.001). MDR-GNB were not detected for three months and ESBL-KP for five months. Multivariate analysis of principal exposure variables showed that admission in post-intervention period significantly reduced the risk of MDR-GNB carriage (adj-OR=0.21, 95% CI=0.076-0.629; p<0.001).Conclusions: MDR-GNB broadly circulate in NICU setting and can colonize different body sites and spread by various vehicles. A coordinated strategy of multiple interventions with active cooperation between epidemiologists and clinicians in the NICU can effectively reduce their circulation and in particular the carriage of most dangerous ESBL-KP strains.

Findings During the intensified microbiological surveillance MDR-GNB and ESBL-KP were detected in rectal swabs (34.8%; 23.2%), nasal swabs (24.6%; 14.5%), oral swabs (14.5%; 5.4%), milk samples (32.1%; 17.9%), pacifiers swabs (30.8%; 17.9%) and from sub-intensive room surfaces. Thirteen ESBL-KP strains isolated from clinical and environmental samples showed identical PFGE patterns. The prevalence of MDR-GNB and ESBL-KP carriage significantly decreased in the year after intervention compared to the previous year (20.6% vs 62.2%; p < 0.001 and 11.1% vs 57.8%; p < 0.001). MDR-GNB were not detected at all for three months and ESBL-KP for five months. Multivariate analysis of the principal exposure variables showed that admission in the post-intervention period significantly reduced the risk of MDR-GNB carriage (adj-OR = 0.21, 95% CI = 0.076–0.629; p < 0.001). Conclusions MDR-GNB broadly circulate in NICU setting, they can colonize different body sites and spread through various vehicles. A coordinated strategy of multiple interventions with active cooperation between epidemiologists and clinicians in the NICU can effectively reduce their circulation and in particular the carriage of the most dangerous ESBL-KP strains.

From November 2017 the following intervention measures were applied: a) two-months strengthening of sample collection; b) stakeholders’ meetings; c) improvement of prevention measures and antimicrobial policy. Prevalence of MDR-GNB carriage observed in the 12 months before and in the 24 months after intervention were compared by chi-square test. Risk factors for MDR-GNB carriage in a subgroup of patients were identified by a multivariate logistic regression model. Findings: During the strengthened microbiological surveillance MDR-GNB and ESBL-KP were detected in rectal swabs (34.8%; 23.2%), nasal swabs (24.6%; 14.5%), oral swabs (14.5%; 5.4%), milk samples (32.1%; 17.9%), soother swabs (30.8%; 17.9%) and from a sub-intensive room surface. Thirteen ESBL-KP strains isolated from clinical and environmental samples showed identical PFGE patterns. ESBL-KP was detected no more until June 2018. No MDR-GNB isolate was detected for three months. Prevalence of MDR-GNB and ESBL-KP carriage after intervention significantly decreased compared to the previous year (20.6% vs 62.2 %; p<0.001 and 11.1% vs 57.8%; p<0.001). Multivariate analysis of principal exposure variables showed that admission in post-intervention period significantly reduced the risk of MDR-GNB carriage (OR=0.15, p=0.01). Conclusions: MDR-GNB broadly circulate in NICU setting and can colonize different body sites and spread by various vehicles. A coordinated strategy of multiple interventions with active cooperation between epidemiologists and clinicians in the NICU can effectively reduce their circulation and in particular the carriage of most dangerous ESBL-KP strains.

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.

Objective: Carbapenem resistance has been reported with increasing frequency among members of Enterobacterales, especially in the last 10 years. Screening and detection of carbapenemase-producing isolates is important in terms of both directing the treatment and preventing its spread. In our study, it was aimed to determine the carbapenemase types and molecular epidemiological relationships of carbapenem resistant Klebsiella pneumoniae isolates, which were isolated sequentially from the samples sent to microbiology laboratory of our hospital. Method: A total of 32 carbapenem-resistant K. pneumoniae isolates of the samples sent to microbiology laboratory between July and September 2014, were included in the study. In addition to classical methods, identification of isolates at species level was made with BD Phoenix ID/AST automated system. Carbapenemase types (blaOXA-48, blaNDM, blaIMP, blaKPC, blaVIM and blaGES) of the isolates were investigated by PCR. The clonal relationship between the isolates was assessed with PFGE. Results: It was noted that 18 isolates were obtained from intensive care units, 9 from inpatient and 5 from outpatient departments. The blaOXA48 gene was found in all isolates while the other carbapenemase genes were not found. It was determined that strains were isolated from 32 patients in our hospital had 12 different PFGE pulsotypes, named as A-L. Among these, the most common ones were B (n=18) and closely related B1 pattern (n=2). The remaining isolates were represented by 11 different types. It was observed that the first isolate with B pulsotype was responsible for the spread of the outbreak from General Intensive Care Unit. Conclusion: It has been thought that the spread of carbapenem- resistant K. pneumoniae isolates in the hospital was probably occurred through the transfer of isolates from patients with gastrointestinal colonization to other patients through hospital staff. Therefore, the spread of the isolates in hospitals can be limited by detecting colonization with active surveillance programs and by applying contact isolation and effective infection control measures.
