AbstractObjectives:To describe an outbreak of hospital-acquired MRSA in a NICU and to identify the risk factors for, outcomes of, and interventions that eliminated it.Setting:An 18-bed, level III-IV NICU in a community hospital.Methods:Interventions to control MRSA included active surveillance, aggressive contact isolation, and cohorting and decolonization of infants and HCWs with MRSA. A case–control study was performed to compare infants with and without MRSA.Results:A cluster of 6 cases of MRSA infection between September and October 2001 represented an increased attack rate of 21.2% compared with 5.3% in the previous months. Active surveillance identified unsuspected MRSA colonization in 6 (21.4%) of 28 patients and 6 (5.5%) of 110 HCWs screened. They were all successfully decolonized. There was an increased risk of MRSA colonization and infection among infants with low birth weight or younger gestational age. Multiple gestation was associated with an increased risk of colonization (OR, 37.5; CI95, 3.9–363.1) and infection (OR, 5.36; CI95, 1.37–20.96). Gavage feeding (OR, 10.33; CI95, 1.28–83.37) and intubation (OR, 5.97; CI95, 1.22–29.31) were associated with increased risk of infection. Infants with MRSA infection had a significantly longer hospital stay than infants without MRSA (51.83 vs 21.46 days;P= .003). Rep-PCR withmectyping and PVL analysis confirmed the presence of a single common strain of hospital-acquired MRSA.Conclusion:Active surveillance, aggressive implementation of contact isolation, cohorting, and decolonization effectively eradicated MRSA from the NICU for 2½ years following the outbreak.

Abstract The epidemiology of methicillin-resistant S. aureus (MRSA) colonization and infections in a 30-bed, level III university-affiliated neonatal intensive care unit was retrospectively investigated (2014-2018). Virulence, resistance genes and clonality of 46 isolates were determined by PCRs and MLST. Of 1538 neonates, 77 (5%) had a positive culture for MRSA; four bacteremias occured. One major clone was identified, ST225 (23/40, 58%), imported from the same maternity hospital. Another clone, ST217, was predominant (4/6) among colonized health care workers. Four isolates classified as ST80 were PVL-positive, four tst-positive, and two etb-positive. Strengthening of infection control measures with emphasis on hand hygiene was applied.

Neonatal Population

Abstract Background Staphylococcus aureus is a well-known cause of hospital acquired infections. Methicillin resistant staphylococcus aureus (MRSA) colonization is a recognized risk factor for invasive infections. The neonatal population in the intensive care unit (NICU) is particularly vulnerable to these types of infections, resulting in high mortality and morbidity. However, only scant data is available to establish the risk for invasive disease in patients with Methicillin sensitive staphylococcus aureus (MSSA). As a result, surveillance and prevention strategies are only address for MRSA colonization. Here, we describe the clinical characteristics of S. aureus colonized patients identified in late 2018 during transmission events in a single center NICU. As a result of the targeted surveillance investigation for MRSA infection control measures, S. aureus colonization was stratified, and we were able to compare the differences in invasive disease between MRSA and MSSA. Methods This is a retrospective chart review of the 47 colonized patients identified during October 2018- January 2019 SA transmission events in single center NICU. Risk factors, clinical characteristics, and the hospital course of these cases, including the proportion of invasive illness were reviewed. Results We found that most clinical characteristic, risk factors, and hospital course were the same between MRSA and MSSA colonized infants (p values > 0.05). Additionally, there was no difference in the proportion of invasive infection between MRSA and MSSA colonized patients (p value > 0.05). The type of invasive infections identified were SSTI, bacteremia, and osteomyelitis. Conclusion The proportion of invasive infection was the same in MSSA and MRSA colonized patients. This data provides us with supportive material for future recommendations of infection control measures for MSSA colonized patients. Disclosures All Authors: No reported disclosures

AbstractObjective:To evaluate the efficacy of patient and staff cohorting to control vancomycin-resistant enterococci (VRE) at an Indianapolis community hospital.Design:To interrupt transmission of VRE, a VRE point-prevalence survey of hospital inpatients was conducted, and VRE-infected or -colonized patients were cohorted on a single ward with dedicated nursing staff and patient-care equipment. To assess the impact of the intervention, staff compliance with contact isolation procedures was observed, and the VRE point-prevalence survey was repeated 2 months after the cohort ward was established.Results:Following the establishment of the cohort ward, VRE prevalence among all hospitalized inpatients decreased from 8.1% to 4.7% (25 positive cultures among 310 patients compared to 13 positive cultures among 276 patients,P=.14); VRE prevalence among patients whose VRE status was unknown before cultures were obtained decreased from 5.9% to 0.8% (18 positive cultures among 303 patients compared to 2 positive cultures among 262 patients,P=.002); and observed staff-patient interactions compliant with published isolation recommendations increased (5 [22%] of 23 interactions compared to 36 [88%] of 41 interactions,P<.0001).Conclusions:Our data suggest that, in hospitals with endemic VRE or continued VRE transmission despite implementation of contact isolation measures, establishing a VRE cohort ward may be a practical and effective method to improve compliance with infection control measures and thereby to control epidemic or endemic VRE transmission.

The COVID-19 pandemic has changed the way we practice medicine and lead our lives. In addition to pulmonary symptoms; COVID-19 as a syndrome has multisystemic involvement including frequent gastrointestinal symptoms such as diarrhea. Due to microbiome alterations with COVID-19 and frequent antibiotic exposure, COVID-19 can be complicated by Clostridioides difficile infection. Co-infection with these two can be associated with a high risk of complications. Infection control measures in hospitals is enhanced due to the COVID-19 pandemic which in turn appears to reduce the incidence of hospital-acquired infections such as C. difficile infection. Another implication of COVID-19 and its potential transmissibility by stool is microbiome-based therapies. Potential stool donors should be screened COVID-19 symptoms and be tested for COVID-19.

Potential Risk Factors

BACKGROUND: Healthcare workers (HCWs) are at the frontline defense against coronavirus disease 2019 (COVID-19) pandemic. AIM: The study aimed to describe the characteristics and appraise potential risk factors of COVID-19 transmission among HCWs who tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in one of Cairo University Hospitals. METHOD: Cross-sectional descriptive analysis of confirmed polymerase chain reaction (PCR) positive versus negative cases for COVID-19. RESULTS: Through March–June 2020, (145/846; 17%) suspected HCWs were tested for COVID-19 by PCR; out of them (70/145; 48.3%) were confirmed as positive, these positive cases represented (70/846; 8.3%) of all HCWs of the hospital. About 33% of confirmed COVID-19 positive HCWs acquired the infection from the healthcare while only (13/70; 19%) from community settings, and no clear exposure data were identified in (34/70; 48%) of cases. Most of symptomatic cases showed a positive PCR test for SARS-CoV-2 versus asymptomatic cases, p < 0.001. There was no statistical significance regarding gender, age, presence of comorbidity, workload or the type of acquisition. CONCLUSION: HCWs are at an increased risk of COVID-19 infection at the workplace. Strict implementation of infection control measures is of crucial role in preventing transmission of COVID-19 infection in health-care settings.

Objective.Describe local changes in the incidence of community-onset and hospital-onset methicillin-resistantStaphylococcus aureus(MRSA) infection and evaluate the impact of MRSA active surveillance on hospital-onset infection.Design.Observational study using prospectively collected data.Setting.Atlanta Veterans Affairs Medical Center (AVAMC).Patients.All patients seen at the AVAMC over an 8-year period with clinically and microbiologically proven MRSA infection.Methods.All clinical cultures positive for MRSA were prospectively identified, and corresponding clinical data were reviewed. MRSA infections were classified into standard clinical and epidemiologic categories. The Veterans Health Administration implemented the MRSA directive in October 2007, which required active surveillance cultures in acute care settings.Results.The incidence of community-onset MRSA infection peaked in 2007 at 5.45 MRSA infections per 1,000 veterans and decreased to 3.14 infections per 1,000 veterans in 2011 (P< .001 for trend). Clinical and epidemiologic categories of MRSA infections did not change throughout the study period. The prevalence of nasal MRSA colonization among veterans admitted to AVAMC decreased from 15.8% in 2007 to 11.2% in 2011 (P<.001 for trend). The rate of intensive care unit (ICU)-related hospital-onset MRSA infection decreased from October 2005 through March 2007, before the MRSA directive. Rates of ICU-related hospital-onset MRSA infection remained stable after the implementation of active surveillance cultures. No change was observed in rates of non-ICU-related hospital-onset MRSA infection.Conclusions.Our study of the AVAMC population over an 8-year period shows a consistent trend of reduction in the incidence of MRSA infection in both the community and healthcare settings. The etiology of this reduction is most likely multifactorial.
