Estimating the effect of active detection and isolation on Clostridioides difficile infections in a bone marrow transplant unit.

OBJECTIVE: To model the effects of active detection and isolation (ADI) regarding Clostridioides difficile infection (CDI) in the bone marrow transplant (BMT) unit of our hospital. SETTING: ADI was implemented in a 21-patient bone marrow unit. PATIENTS: Patients were bone marrow recipients on this unit. INTERVENTIONS: We compared active ADI, in which patients who tested positive for colonization of C. difficile before their hospital stay were placed under extra contact precautions, with cases not under ADI. RESULTS: Within the BMT unit, ADI reduced total cases of CDI by 24.5% per year and reduced hospital-acquired cases by ∼84%. The results from our simulations also suggest that ADI can save ∼$67,600 per year in healthcare costs. CONCLUSIONS: Institutions with active BMT units should consider implementing ADI.

Reducing Central Line Associated Bloodstream Infections (CLABSIs) by Reducing Central Line Days.

PURPOSE OF REVIEW: While reducing unnecessary days present of central venous catheters (CVCs) is part of central line associated bloodstream infection (CLABSI) best practices, there is limited information regarding compliance with this recommendation as well as addressing barriers to compliance. RECENT FINDINGS: Significant work has been directed towards daily audits of necessity and improving communication between members of the medical team. Other critical interventions include utilization of the electronic health record (EHR), leadership support of CLABSI reduction goals, and avoiding CVC placement over more appropriate vascular access. SUMMARY: Institutions have varied approaches to addressing the issue of removing idle CVCs, and more standardized approaches in checklists as well as communication, particularly on multidisciplinary rounds, will be key to CVC removal. Utilization of the EHR for reminders or appropriate documentation of necessity is a factor. Avoidance of placing a CVC or appropriateness of the CVC is also important to consider.

You get back what you give: Decreased hospital infections with improvement in CHG bathing, a mathematical modeling and cost analysis.

BACKGROUND: Multiple studies have shown that bathing with chlorhexidine gluconate (CHG) wipes reduces hospital-acquired infections (HAIs). We employed a mathematical model to assess the impact of CHG patient bathing on central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and hospital-onset Clostridium difficile (C diff) infections and the associated costs. METHODS: Using a Markov chain, we examined the effect of CHG bathing compliance on HAI outcomes and the associated costs. Using estimates from 2 different studies on CHG bathing effectiveness for CLABSI, CAUTI, and C diff, the number of HAIs per year were estimated along with associated costs. The simulations were conducted, assuming CHG bathing at varying compliance rates. RESULTS: At 32% reduction in HAI incidence, increasing CHG bathing compliance from 60% to 90% results in 20 averted infections and $815,301.75 saved cost. CONCLUSIONS: As CHG bathing compliance increases, yearly HAIs decrease, and the overall cost associated with the HAIs also decreases.

Knowledge, attitudes, and practices of bedside nursing staff regarding antibiotic stewardship: A cross-sectional study.

BACKGROUND: Nursing engagement in antibiotic stewardship programs (ASPs) remains suboptimal. The purpose of this study was to determine the knowledge, attitudes, and practices of nursing staff members regarding ASPs and identify barriers to their participation in such programs. METHODS: This cross-sectional study was conducted at Virginia Commonwealth University Health System, an 860-bed tertiary care academic center located in Richmond, Virginia, where a well-resourced ASP has been in place for 2 decades. A survey consisting of 12 questions was administered to nursing staff via REDCap (Research Electronic Data Capture) in February 2018. RESULTS: A total of 159 survey responses were included in the study. The results demonstrated gaps in knowledge regarding antibiotic stewardship (AS) and highlighted the importance of improving communication between nurses and ASPs. Overall, 102 (64.15%) of the study participants indicated familiarity with AS. Time constraints and concerns over physician pushback were identified as major barriers to participation. CONCLUSIONS: Many nurses were unaware of our center's ASP. Nurses identified activities falling within their daily workflow as potential areas for contribution to ASPs. Key barriers to participation were also identified. These data will inform efforts to engage nursing in AS activities at our medical center.

Chlorhexidine gluconate bathing: Patient perceptions, practices, and barriers at a tertiary care center.

Many studies indicate that daily chlorhexidine gluconate (CHG) bathing reduces the risk of hospital-acquired infections. In this study, we found that patient perceptions can be a barrier to bathing practice, and many independent-care patients do not use CHG bathing products correctly. Furthermore, electronic medical record documentation may be a reliable tool to assess CHG bathing compliance.

Impact of Discontinuing Contact Precautions for Methicillin-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococcus: An Interrupted Time Series Analysis.

OBJECTIVETo investigate the impact of discontinuing contact precautions among patients infected or colonized with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) on rates of healthcare-associated infection (HAI). DESIGN: Single-center, quasi-experimental study conducted between 2011 and 2016.METHODSWe employed an interrupted time series design to evaluate the impact of 7 horizontal infection prevention interventions across intensive care units (ICUs) and hospital wards at an 865-bed urban, academic medical center. These interventions included (1) implementation of a urinary catheter bundle in January 2011, (2) chlorhexidine gluconate (CHG) perineal care outside ICUs in June 2011, (3) hospital-wide CHG bathing outside of ICUs in March 2012, (4) discontinuation of contact precautions in April 2013 for MRSA and VRE, (5) assessments and feedback with bare below the elbows (BBE) and contact precautions in August 2014, (6) implementation of an ultraviolet-C disinfection robot in March 2015, and (7) 72-hour automatic urinary catheter discontinuation orders in March 2016. Segmented regression modeling was performed to assess the changes in the infection rates attributable to the interventions.RESULTSThe rate of HAI declined throughout the study period. Infection rates for MRSA and VRE decreased by 1.31 (P=.76) and 6.25 (P=.21) per 100,000 patient days, respectively, and the infection rate decreased by 2.44 per 10,000 patient days (P=.23) for device-associated HAI following discontinuation of contact precautions.CONCLUSIONThe discontinuation of contact precautions for patients infected or colonized with MRSA or VRE, when combined with horizontal infection prevention measures was not associated with an increased incidence of MRSA and VRE device-associated infections. This approach may represent a safe and cost-effective strategy for managing these patients.Infect Control Hosp Epidemiol 2018;39:676-682.
