Emergence of carbapenem-resistant Enterobacteriaceae in Orange County, California, and support for early regional strategies to limit spread.
BackgroundThe east-to-west spread of carbapenem-resistant Enterobacteriaceae (CRE) represents an opportunity to explore strategies to limit spread in nonendemic areas. We evaluated CRE emergence and regional support for containment strategies.MethodsA 17-question cross-sectional survey was administered to infection prevention programs in Orange County, CA (31 hospitals serving 3 million residents), between January and September 2014. Questions addressed newly detected hospital- and community-onset CRE cultures (2008-2013), current CRE control strategies, and support for prevention strategies for a hypothetical regional intervention.ResultsAmong 31 hospitals, 21 (68%, representing 17 infection prevention programs) completed the survey. CRE was scarcely detected between 2009-2010; within 4 years, 90% of hospitals reported CRE, with 2.5-fold higher community-onset than hospital-onset CRE. Between 2011 and 2013, annual CRE incidence increased 4.7-fold (1.4-6.3 cases/10,000 admissions). Support for a regional CRE prevention bundle was unanimous. Although 22% bathed patients positive for CRE with chlorhexidine gluconate and 11% actively screened for CRE, 86% and 57%, respectively, would consider these strategies in a regional intervention.ConclusionsCRE epidemiology in Orange County parallels early progression previously seen in now-endemic areas, representing an opportunity to consider interventions to prevent endemic spread. Many facilities would consider proactive strategies, such as chlorhexidine bathing, in the setting of a regional collaborative

Double-swab 5% versus single-swab 10% iodophor for reducing methicillin-resistant Staphylococcus aureus with routine chlorhexidine bathing.
In a prospective cohort study, we compared a 2-swabs-per-nostril 5% iodophor regimen with a 1-swab-per-nostril 10% iodophor regimen on methicillin-resistant Staphylococcus aureus carriage in nursing-home residents. Compared with baseline, both single-swab and double-swab regimens resulted in an identical 40% reduction in nasal carriage and 60% reduction in any carriage, skin or nasal
Prevalence of and Factors Associated With Multidrug Resistant Organism (MDRO) Colonization in 3 Nursing Homes.
Nursing home residents are at risk for acquiring and transmitting MDROs. A serial point-prevalence study of 605 residents in 3 facilities using random sampling found MDRO colonization in 45% of residents: methicillin-resistant Staphylococcus aureus (MRSA, 26%); extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL, 17%); vancomycin-resistant Enterococcus spp. (VRE, 16%); carbapenem-resistant Enterobacteriaceae (CRE, 1%). MDRO colonization was associated with history of MDRO, care needs, incontinence, and catheters. Infect Control Hosp Epidemiol 2016;1485-1488

Impact of a Central-Line Insertion Site Assessment (CLISA) score on localized insertion site infection to prevent central-line-associated bloodstream infection (CLABSI).
ObjectiveTo assess the impact of a newly developed Central-Line Insertion Site Assessment (CLISA) score on the incidence of local inflammation or infection for CLABSI prevention.DesignA pre- and postintervention, quasi-experimental quality improvement study.Setting and participantsAdult inpatients with central venous catheters (CVCs) hospitalized in an intensive care unit or oncology ward at a large academic medical center.MethodsWe evaluated CLISA score impact on insertion site inflammation and infection (CLISA score of 2 or 3) incidence in the baseline period (June 2014-January 2015) and the intervention period (April 2015-October 2017) using interrupted times series and generalized linear mixed-effects multivariable analyses. These were run separately for days-to-line removal from identification of a CLISA score of 2 or 3. CLISA score interrater reliability and photo quiz results were evaluated.ResultsAmong 6,957 CVCs assessed 40,846 times, percentage of lines with CLISA score of 2 or 3 in the baseline and intervention periods decreased by 78.2% (from 22.0% to 4.7%), with a significant immediate decrease in the time-series analysis (P < .001). According to the multivariable regression, the intervention was associated with lower percentage of lines with a CLISA score of 2 or 3, after adjusting for age, gender, CVC body location, and hospital unit (odds ratio, 0.15; 95% confidence interval, 0.06-0.34; P < .001). According to the multivariate regression, days to removal of lines with CLISA score of 2 or 3 was 3.19 days faster after the intervention (P < .001). Also, line dwell time decreased 37.1% from a mean of 14 days (standard deviation [SD], 10.6) to 8.8 days (SD, 9.0) (P < .001). Device utilization ratios decreased 9% from 0.64 (SD, 0.08) to 0.58 (SD, 0.06) (P = .039).ConclusionsThe CLISA score creates a common language for assessing line infection risk and successfully promotes high compliance with best practices in timely line removal

Chlorhexidine and Mupirocin for Clearance of Methicillin Resistant Staphylococcus aureus Colonization After Hospital Discharge: A Secondary Analysis of the CLEAR Trial.
BackgroundThe CLEAR trial demonstrated that a multi-site body decolonization regimen reduced post-discharge infection and hospitalization in methicillin-resistant Staphylococcus aureus (MRSA) carriers. This report describes decolonization efficacy in clearing site-specific MRSA colonization during the trial.MethodsWe performed a large, multi-center, randomized clinical trial of MRSA decolonization among adult patients after hospital discharge with MRSA infection or colonization. Participants were randomized 1:1 to either MRSA prevention education or education plus decolonization with 4% topical chlorhexidine daily, 0.12% oral chlorhexidine rinse twice daily, and 2% nasal mupirocin twice daily. The intervention was given for five consecutive days twice monthly. Participants were swabbed in the nares, throat, axilla/groin, and wound (if applicable) at baseline, 1, 3, 6, and 9 months after randomization. The primary outcomes of this report are follow-up colonization differences between groups.ResultsAmong 2,121 participants, 1,058 were randomized to the decolonization group. By one month, MRSA colonization was lower in the decolonization group compared to the education only group (OR = 0.44 [95% Confidence Interval 0.36-0.54, p≤0.001). Similar magnitude of reduction was seen in the nares (OR = 0.34 [0.27-0.42], p < 0.001) throat (OR = 0.55 [0.42-0.73], p < 0.001), and axilla/groin (OR = 0.57 [0.43-0.75], p < 0.001). These differences persisted through month 9 except at the wound site, which had a relatively small sample size. Higher regimen adherence was associated with lower MRSA colonization (p≤0.01).ConclusionIn a randomized clinical trial, a repeated post-discharge decolonization regimen for MRSA carriers reduced MRSA colonization overall and at multiple body sites. Higher treatment adherence was associated with greater reductions in MRSA colonization
