Abstract Background The unrestricted use of linezolid has been linked to the emergence of linezolid-resistant Staphylococcus epidermidis (LRSE). We report the effects of combined antibiotic stewardship and infection control measures on the spread of LRSE in an intensive care unit (ICU). Methods Microbiological data were reviewed to identify all LRSE detected in clinical samples at an ICU in southwest Germany. Quantitative data on the use of antibiotics with Gram-positive coverage were obtained in defined daily doses (DDD) per 100 patient-days (PD). In addition to infection control measures, an antibiotic stewardship intervention was started in May 2019, focusing on linezolid restriction and promoting vancomycin, wherever needed. We compared data from the pre-intervention period (May 2018–April 2019) to the post-intervention period (May 2019–April 2020). Whole-genome sequencing (WGS) was performed to determine the genetic relatedness of LRSE isolates. Results In the pre-intervention period, LRSE were isolated from 31 patients (17 in blood cultures). The average consumption of linezolid and daptomycin decreased from 7.5 DDD/100 PD and 12.3 DDD/100 PD per month in the pre-intervention period to 2.5 DDD/100 PD and 5.7 DDD/100 PD per month in the post-intervention period (p = 0.0022 and 0.0205), respectively. Conversely, vancomycin consumption increased from 0.2 DDD/100 PD per month to 4.7 DDD/100 PD per month (p < 0.0001). In the post-intervention period, LRSE were detected in 6 patients (4 in blood cultures) (p = 0.0065). WGS revealed the predominance of one single clone. Conclusions Complementing infection control measures by targeted antibiotic stewardship interventions was beneficial in containing the spread of LRSE in an ICU.

Background.In 1998, a study in the intensive care unit (ICU) of our institution suggested possible transmission of Pseudomonas aeruginosa from faucet to patient and from patient to patient. Infection-control measures were implemented to reduce the degree ofP. aeruginosacolonization in faucets, to reduce the use of faucet water in certain patient care procedures, and to reduce the rate of transmission from patient to patient.Objective.To evaluate the effect of the control measures instituted in 1999 to preventP. aeruginosainfection and colonization in ICU patients.Design.Prospective, molecular, epidemiological investigation.Setting.A 870-bed, university-affiliated, tertiary care teaching hospital.Methods.The investigation was performed in a manner identical to the 1998 investigation. ICU patients with a clinical specimen positive forP. aeruginosawere identified prospectively. Swab specimens from the inner part of the ICU faucets were obtained for the culture on 9 occasions between September 1997 and December 2000. All patients and environmental isolates were typed by pulsed-field gel electrophoresis (PFGE).Results.Compared with the 1998 study, in 2000 we found that the annual incidence of ICU patients colonized or infected withP. aeruginosahad decreased by half (26.6 patients per 1,000 admissions in 2000 vs 59.0 patients per 1,000 admissions in 1998), although the populations of patients were comparable. This decrease was the result of the decreased incidence of cases in which an isolate had a PFGE pattern identical to that of an isolate from a faucet (7.0 cases per 1,000 admissions in 2000, vs 23.6 per 1,000 admissions in 1998) or from another patient (6.5 cases per 1,000 admissions in 2000 vs 16.5 cases per 1,000 admissions in 1998), whereas the incidence of cases in which the isolate had a unique PFGE pattern remained nearly unchanged (13.1 cases per 1,000 admissions in 2000 vs 15.6 cases per 1,000 admissions in 1998).Conclusions.These results suggest that infection control measures were effective in decreasing the rate ofP. aeruginosacolonization and infection in ICU patients, confirming thatP. aeruginosastrains were of exogenous origin in a substantial proportion of patients during the preintervention period.


This case focuses on reducing catheter-related bloodstream infections in the intensive care unit (ICU) by asking the question: Can rates of catheter-related bloodstream infections be reduced by implementing a safety initiative involving five simple infection-control measures by ICU staff? Implementation of a safety initiative involving five simple infection-control measures by ICU staff was associated with a substantial reduction in catheter-related bloodstream infections. While it is not certain that the safety initiative—rather than other factors—was responsible for the observed reduction, the study provides strong evidence that this safety initiative should be implemented widely.

ObjectiveWe describe the efficacy of enhanced infection control measures, including those recommended in the Centers for Disease Control and Prevention’s 2012 carbapenem-resistant Enterobacteriaceae (CRE) toolkit, to control concurrent outbreaks of carbapenemase-producing Enterobacteriaceae (CPE) and extensively drug-resistantAcinetobacter baumannii(XDR-AB).DesignBefore-after intervention study.SettingFifteen-bed surgical trauma intensive care unit (ICU).MethodsWe investigated the impact of enhanced infection control measures in response to clusters of CPE and XDR-AB infections in an ICU from April 2009 to March 2010. Polymerase chain reaction was used to detect the presence ofblaKPCand resistance plasmids in CRE. Pulsed-field gel electrophoresis was performed to assess XDR-AB clonality. Enhanced infection-control measures were implemented in response to ongoing transmission of CPE and a new outbreak of XDR-AB. Efficacy was evaluated by comparing the incidence rate (IR) of CPE and XDR-AB before and after the implementation of these measures.ResultsThe IR of CPE for the 12 months before the implementation of enhanced measures was 7.77 cases per 1,000 patient-days, whereas the IR of XDR-AB for the 3 months before implementation was 6.79 cases per 1,000 patient-days. All examined CPE shared endemicblaKPCresistance plasmids, and 6 of the 7 XDR-AB isolates were clonal. Following institution of enhanced infection control measures, the CPE IR decreased to 1.22 cases per 1,000 patient-days (P= .001), and no more cases of XDR-AB were identified.ConclusionsUse of infection control measures described in the Centers for Disease Control and Prevention’s 2012 CRE toolkit was associated with a reduction in the IR of CPE and an interruption in XDR-AB transmission.

Abstract Background Hoop’s Family Children’s Hospital is a pediatric hospital with 72 beds, nested within Cabell Huntington Hospital. There is an established adult antibiotic stewardship program (ASP), however, since 2014 there has not been a pediatric infectious disease (ID) specialist and no pediatric ASP. With the recent hire of a pediatric ID specialist in Oct 2019 and the formation of a targeted pediatric ASP, we tracked the use of ceftriaxone (CRO) in our facility. Methods Starting January 2020, education was provided to pediatric providers in regards to appropriate CRO dosing and clinical indications via email communication. The main goals were to limit 100mg/kg/day dosing to severe infections and reduce CRO use in community-acquired pneumonia. This was sustained through intermittent prospective audits and feedback. A retrospective chart review was done from 2019-2021 for the months of January, April and December of each year. Patients ≤18 years of age who received CRO were included. Dosing, interval frequency, indication, and treatment duration were reviewed. Patients who received a single dose of CRO were excluded. Results From Jan 2019 – April 2021, 391 patient charts were reviewed (189 in the pre-intervention period and 202 in the post intervention period). There were no significant differences in age, race/ethnicity and gender in the two study groups. In the pre-intervention period, 86% of patients were prescribed CRO at severe infection dosing vs 33% in the post intervention period (p&lt; 0.0001) (Figure 1). When dosing was paired with indication, only 20% of patients in the pre intervention period had the appropriate dosing per clinical indication compared to 83% in the post intervention period (p&lt; 0.0001) (Figure 2). We also saw that in the pre-intervention period the most common indication for CRO was pneumonia (66%), which decreased to 57% in 2020 and to 35% in 2021 (p&lt; 0.0001) (Figure 3). Figure 1 describes the percentage of patients receiving ceftriaxone at severe infection dosing. This changed from an average of 86% in the pre-intervention period to 33% in the post-intervention period. Figure 2 describes the percentage of patients receiving ceftriaxone at the appropriate dosing dependent on the clinical indication provided. This changed from 20% in the pre-intervention period to closer to 90% in the post-intervention period. Conclusion Pediatric specific ASP efforts and expertise proved to be crucial in appropriate CRO use in our institution. With a feasible education strategy and targeted prospective audit and feedback, there has been a sustained impact in inappropriate CRO use. This underscores the importance of targeted pediatric ASP efforts in pediatric hospitals within larger adult hospitals. Disclosures All Authors: No reported disclosures

Abstract Nosocomially acquired completely resistant Acinetobacter baumannii strains are a major clinical concern. We identified completely resistant A. baumannii in 6 (4.9%) of 122 A. baumannii isolates in a retrospective chart review at two teaching hospitals. All of these patients had received broad-spectrum antibiotics and had severe underlying comorbid illnesses, long hospitalizations, or recent surgical procedures; 3 had been in the intensive care unit. Five (83%) of the 6 patients were older than 70 years. Only one death occurred. Strict infection control measures may limit further spread.
