AbstractBackground and Objective:At the University Medical Center Utrecht (UMCU), follow-up implies an inventory of risk factors and screening for MRSA colonization among all MRSA-positive patients for at least 6 months. If risk factors or positive cultures persist or re-emerge, longer follow-up is indicated and isolation at readmission. This study investigated how long MRSA-positive patients remained colonized after hospital discharge and which risk factors were important. Furthermore, the results of eradication therapy were evaluated.Design:All patients who were positive for MRSA at the UMCU between January 1991 and January 2001 were analyzed regarding carriage state, presence of risk factors for prolonged carriage ofStaphylococcus aureus, and eradication treatment.Results:A total of 135 patients were included in the study. The median follow-up time was 1.2 years. Eighteen percent of the patients were dismissed from follow-up 1 year after discharge. Only 5 patients were dismissed after 6 months. Among patients with no risk factors, eradication treatment was effective for 95% within 1 year. Among patients with persistent risk factors, treatment was effective for 89% within 2 years.Conclusions:Based on these findings, eradication therapy should be prescribed for all MRSA carriers, independent of the presence of risk factors. MRSA-positive patients should be evaluated for 6 months for the presence of risk factors and MRSA carriage. Screening for risk factors is important because intermittent MRSA carriage was found in a significant number of our patients. Patients with negative MRSA cultures and without risk factors for 12 months can be safely dismissed from follow-up. (Infect Control Hosp Epidemiol 2005;26:629-633)

Objective.The incidence of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections in the United States decreased during 2005–2008, but noninvasive community-associated MRSA (CA-MRSA) infections also frequently lead to hospitalization. We estimated the incidence of all MRSA infections among inpatients at US academic medical centers (AMCs) per 1,000 admissions during 2003–2008.Design.Retrospective cohort study.Setting and Participants.Hospitalized patients at 90% of nonprofit US AMCs during 2003–2008.Methods.Administrative data on MRSA infections from a hospital discharge database (University HealthSystem Consortium [UHC]) were adjusted for underreporting of the MRSA V09.0 International Classification of Diseases, Ninth Revision, Clinical Modification code and validated using chart reviews for patients with known MRSA infections in 2004–2005, 2006, and 2007.Results.The mean sensitivity of administrative data for MRSA infections at the University of Chicago Medical Center in three 12-month periods during 2004–2007 was 59.1%. On the basis of estimates of billing data sensitivity from the literature and the University of Chicago Medical Center, the number of MRSA infections per 1,000 hospital discharges at US AMCs increased from 20.9 (range, 11.1–47.7) in 2003 to 41.7 (range, 21.9–94.0) in 2008. At the University of Chicago Medical Center, among infections cultured more than 3 days prior to hospital discharge, CA-MRSA infections were more likely to be captured in the UHC billing-derived data than were healthcare-associated MRSA infections.Conclusions.The number of hospital admissions for any MRSA infection per 1,000 hospital admissions overall increased during 2003–2008. Use of unadjusted administrative hospital discharge data or surveillance for invasive disease far underestimates the number of MRSA infections among hospitalized patients.

AbstractBackground and Objective:The benefit of screening healthcare workers (HCWs) at risk for methicillin-resistantStaphylococcus aureus(MRSA) carriage and furloughing MRSA-positive HCWs to prevent spread to patients is controversial. We evaluated our MRSA program for HCWs between 1992 and 2002.Setting:A university medical center in the Netherlands, where methicillin resistance has been kept below 0.5% of all nosocomial S.aureusinfections using active surveillance cultures and isolation of colonized patients.Design:HCWs caring for MRSA-positive patients or patients in foreign hospitals were screened for MRSA. MRSA-positive HCWs had additional cultures, temporary exclusion from patient-related work, assessment of risk factors for persisting carriage, decolonization therapy with mupirocin intranasally and chlorhexidine baths for skin and hair, and follow-up cultures.Results:Fifty-nine HCWs were colonized with MRSA. Seven of 840 screened employees contracted MRSA in foreign hospitals; 36 acquired MRSA after contact with MRSA-positive patients despite isolation precautions (attack rate per outbreak varied from less than 1% to 15%). Our hospital experienced 17 MRSA outbreaks, including 13 episodes in which HCWs were involved. HCWs were index cases of at least 4 outbreaks. In 8 outbreaks, HCWs acquired MRSA after caring for MRSA-positive patients despite isolation precautions.Conclusion:Postexposure screening of HCWs allowed early detection of MRSA carriage and prevention of subsequent transmission to patients. Where the MRSA prevalence is higher, the role of HCWs may be greater. In such settings, an adapted version of our program could help prevent dissemination.

Background and objectives: Approximately 25% of patients who present with acute ischemic stroke are wake-up strokes. These patients are often not treated with IV thrombolytics because of unclear onset of symptoms. Little data exists on endovascular therapy as acute treatment for this population, particularly with an aspiration technique. The objective of this study is to compare outcomes of patients who presented with wake-up strokes due to large vessel occlusion treated with neuroendovascular procedures versus those who received conservative treatment, based on a 2-year (2012-2013), single center experience at Ochsner Medical Center in New Orleans, LA. Method: 24 consecutive patients, who presented with wake-up strokes, were outside the IV tPA window, and had both CTA confirmed intracranial LVO and CT-perfusion data upon arrival to our institution were retrospectively studied. Patients with hemorrhages, tandem lesions, or high-grade carotid stenosis were excluded from this analysis. Decision to perform endovascular treatment was made by the vascular neurologist and neuro-interventionalist based on stroke severity and CTA/perfusion data. Patients in group 1 (n = 8) underwent endovascular revascularization procedures; patients in group 2 (n = 16) were treated conservatively (medical management alone). Presentation NIHSS, risk factors, mortality, discharge NIHSS, discharge mRS, and follow up mRS were compared. Results: There were no statistical differences in patient population regarding age, gender, and risk factors. There was no statistical difference in their initial NIHSS (16.8 vs. 21.8, p=0.05162), or mortality (0% vs 21%, pr=0.262). The two groups were statistically different in their discharge NIHSS (7.25 vs 21.81, p<0.00045), discharge mRS (2 vs 5, p<0.00001), clinic follow up mRS (1.37 vs 4.94, p<0.00001), and good outcome at discharge (mRS 0-2)(75% vs 0%, pr<0.0002). Conclusion: Patients with wake-up strokes, LVO, and favorable CT-perfusion data who underwent neuroendovascular reperfusion treatment had significantly better outcomes in our population, despite similar stroke severity at presentation. This suggests that with careful selection, neuroendovascular therapy for wake-up strokes may lead to improved outcomes.

AbstractObjective:To implement a comprehensive infection control (IC) program for prevention of cardiac device-associated infections (CDIs).Design:Prospective before-after trial with 2 years of follow-up.Setting:A tertiary-care, university-affiliated medical center.Patients:A consecutive sample of all adults undergoing cardiac device implantation between 1997 and 2002.Intervention:An IC program was implemented during late 2001 and included staff education, preoperative modification of patient risk factors, intraoperative control of strict aseptic technique, surgical scrubbing and attire, control of environmental risk factors, optimization of antibiotic prophylaxis, postoperative wound care, and active surveillance. The clinical endpoint was CDI rates.Results:Between 1997 and 2000, there were 7 CDIs among 725 procedures (mean annual CDI incidence, 1%). During the first 9 months of 2001, there were 7 CDIs among 167 procedures (4.2%; P = .007): CDIs increased from 7 among 576 to 3 among 124 following pacemaker implantation (P = .39) and from 0 among 149 to 4 among 43 following cardioverter-defibrillator implantation (P = .002). Of the 14 CDIs, 5 involved superficial wounds, 7 involved deep wounds, and 2 involved endocarditis. Following intervention, there were no cases of CDI among 316 procedures during 24 months of follow-up (4.2% reduction; P = .0005).Conclusions:We observed a high CDI rate associated with substantial morbidity. IC measures had an impact on CDI. Although the relative weight of each measure in the prevention of CDI remains unknown, our results suggest that implementation of a comprehensive IC program is feasible and efficacious in this setting.

In an effort to reduce early hospital readmissions, Vanderbilt University Medical Center (VUMC) implemented a transitional care coordinator (TCC) to provide careful coordinated follow up care for stroke patients after hospital discharge. The aim of this study is to compare all cause thirty- day readmission rates of adult patients with a primary diagnosis of stroke before and after the implementation of a stroke services TCC. All adult patients admitted to VUMC with a primary diagnosis of stroke; ischemic, hemorrhagic, and TIA; and readmitted within the first thirty days following hospital discharge between January-June of 2015, 2016, 2017, & 2018 were analyzed. Readmission data from 2015 & 2016, prior to the implementation of the TCC was compared to readmission data from 2017 & 2018, after the TCC was implemented. A total of 1911 charts were reviewed for the timeframe January-June of 2015-2018. In 2015 there were 369 stroke admissions and 120 (33%) were readmitted and in 2016 there were 474 stroke admissions and 112 (24%) readmissions, before the TCC role was implemented. In 2017 there were 540 stroke admissions and 62 (11%) were readmitted and in 2018 there were 528 stroke admissions and 74 (14%) readmissions, after the TCC role was implemented. Hospital readmissions were reduced significantly after implementing a TCC.

Abstract Background Jails may facilitate spread of methicillin-resistant Staphylococcus aureus (MRSA) in urban areas. We examined MRSA colonization upon entrance to a large urban jail to determine if there are MRSA transmission networks preceding incarceration. Methods Males incarcerated in Cook County Jail (Chicago) were enrolled, with enrichment for people living with human immunodeficiency virus (PLHIV), within 72 hours of intake. Surveillance cultures assessed prevalence of MRSA colonization. Whole-genome sequencing (WGS) identified preincarceration transmission networks. We examined methicillin-resistant Staphylococcus aureus (MRSA) isolates to determine if there are transmission networks that precede incarceration. A large proportion of individuals enter jail colonized with MRSA. Molecular epidemiology and colonization risk factors provide clues to community reservoirs for MRSA. Results There were 718 individuals (800 incarcerations) enrolled; 58% were PLHIV. The prevalence of MRSA colonization at intake was 19%. In multivariate analysis, methamphetamine use, unstable housing, current/recent skin infection, and recent injection drug use were predictors of MRSA. Among PLHIV, recent injection drug use, current skin infection, and HIV care at outpatient clinic A that emphasizes comprehensive care to the lesbian, gay, bisexual, transgender community were predictors of MRSA. Fourteen (45%) of 31 detainees with care at clinic A had colonization. WGS revealed that this prevalence was not due to clonal spread in clinic but rather to an intermingling of distinct community transmission networks. In contrast, genomic analysis supported spread of USA500 strains within a network. Members of this USA500 network were more likely to be PLHIV (P &lt; .01), men who have sex with men (P &lt; .001), and methamphetamine users (P &lt; .001). Conclusions A large proportion of individuals enter jail colonized with MRSA. Molecular epidemiology and colonization risk factors provide clues to identify colonized detainees entering jail and potential community reservoirs of MRSA.

SUMMARYTo assess the prevalence and risk factors for colonization withStaphylococcus aureusin inmates entering two maximum-security prisons in New York State, USA, inmates (N = 830) were interviewed and anterior nares and oropharyngeal samples collected. Isolates were characterized usingspatyping. Overall, 50·5% of women and 58·3% of men were colonized withS. aureusand 10·6% of women and 5·9% of men were colonized with MRSA at either or both body sites. Of MSSA isolates, the major subtypes werespatype 008 and 002. Overall, risk factors forS. aureuscolonization varied by gender and were only found in women and included younger age, fair/poor self-reported general health, and longer length of prior incarceration. Prevalence of MRSA colonization was 8·2%, nearly 10 times greater than in the general population. Control of epidemicS. aureusin prisons should consider the constant introduction of strains by new inmates.

Objective.To identify risk factors for acquisition of methicillin-resistant Staphylococcus aureus (MRSA) in patients exposed to an MRSA-colonized roommate.Design.Retrospective cohort study.Setting.A 472-bed acute-care teaching hospital in Toronto, Canada.Patients.Inpatients who shared a room between 1996 and 2004 with a patient who had unrecognized MRSA colonization.Methods.Exposed roommates were identified from infection-control logs and from results of screening for MRSA in the microbiology database. Completed follow-up was defined as completion of at least 2 sets of screening cultures (swab samples from the nares, the rectum, and skin lesions), with at least 1 set of samples obtained 7–10 days after the last exposure. Chart reviews were performed to compare those who did and did not become colonized with MRSA.Results.Of 326 roommates, 198 (61.7%) had completed follow-up, and 25 (12.6%) acquired MRSA by day 7–10 after exposure was recognized, all with strains indistinguishable by pulsed-field gel electrophoresis from those of their roommate. Two (2%) of 101 patients were not colonized at day 7–10 but, with subsequent testing, were identified as being colonized with the same strain as their roommate (one at day 16 and one at day 18 after exposure). A history of alcohol abuse (odds ratio [OR], 9.8 [95% confidence limits {CLs}, 1.8, 53]), exposure to a patient with nosocomially acquired MRSA (OR, 20 [95% CLs, 2.4,171]), increasing care dependency (OR per activity of daily living, 1.7 [95% CLs, 1.1, 2.7]), and having received levofloxacin (OR, 3.6 [95% CLs, 1.1,12]) were associated with MRSA acquisition.Conclusions.Roommates of patients with MRSA are at significant risk for becoming colonized. Further study is needed of the impact of hospital antimicrobial formulary decisions on the risk of acquisition of MRSA.
