Objective
To estimate the frequency of MRSA transmission to gowns and gloves worn by healthcare personnel (HCP) interacting with nursing home residents in order to inform infection prevention policies in this setting
Design
Observational study
Setting and Participants
Residents and HCP from 13 community-based nursing homes in Maryland and Michigan
Methods
Residents were cultured for MRSA at the anterior nares and perianal or perineal skin. HCP wore gowns and gloves during usual care activities. At the end of each activity, a research coordinator swabbed the HCP’s gown and gloves.
Results
403 residents were enrolled; 113 were MRSA colonized. Glove contamination was higher than gown contamination (24% vs. 14% of 954 interactions, p<0.01). Transmission varied greatly by type of care from 0% to 24% for gowns and 8% to 37% for gloves. We identified high risk activities (OR >1.0, p< 0.05) including: dressing, transferring, providing hygiene, changing linens and toileting the resident. We identified low risk activities (OR <1.0, p< 0.05) including: giving medications and performing glucose monitoring. Residents with chronic skin breakdown had significantly higher rates of gown and glove contamination.
Conclusions
MRSA transmission from MRSA positive residents to HCP gown and gloves is substantial with high contact activities of daily living conferring the highest risk. These activities do not involve overt contact with body fluids, skin breakdown or mucous membranes suggesting the need to modify current standards of care involving the use of gowns and gloves in this setting.
Background and purpose: The COVID-19 pandemic has required the adaptation of hyperacute stroke care (including stroke code pathways) and hospital stroke management. There remains a need to provide rapid and comprehensive assessment to acute stroke patients while reducing the risk of COVID-19 exposure, protecting healthcare providers, and preserving personal protective equipment (PPE) supplies. While the COVID infection is typically not a primary cerebrovascular condition, the downstream effects of this pandemic force adjustments to stroke care pathways to maintain optimal stroke patient outcomes. Methods: The University of California San Diego (UCSD) Health System encompasses two academic, Comprehensive Stroke Centers (CSCs). The UCSD Stroke Center reviewed the national COVID-19 crisis and implications on stroke care. All current resources for stroke care were identified and adapted to include COVID-19 screening. The adjusted model focused on comprehensive and rapid acute stroke treatment, reduction of exposure to the healthcare team, and preservation of PPE. Aims: The adjusted pathways implement telestroke assessments as a specific option for all inpatient and outpatient encounters and accounts for when telemedicine systems are not available or functional. COVID screening is done on all stroke patients. We outline a model of hyperacute stroke evaluation in an adapted stroke code protocol and novel methods of stroke patient management. Conclusions: The overall goal of the model is to preserve patient access and outcomes while decreasing potential COVID-19 exposure to patients and healthcare providers. This model also serves to reduce the use of vital PPE. It is critical that stroke providers share best practices via academic and vetted social media platforms for rapid dissemination of tools and care models during the COVID-19 crisis.
Tyrosine kinase inhibitor (TKI) therapy for chronic myeloid leukemia (CML) has been associated with progressive peripheral arterial disease and, more recently, rare cases of intracranial vascular stenosis have been reported. We report the fourth case of TKI treatment associated intracranial vasculopathy and rapid progression of intracranial vascular stenosis following intracranial stent placement. This was a 49-year-old woman who developed right-sided weakness, paresthesias, numbness, and speech difficulties 7 years following TKI treatment for CML. Cerebral catheter angiography demonstrated 90% stenosis of the left supraclinoid internal carotid artery, for which the patient underwent intracranial stent placement with no residual stenosis and improved distal blood flow. Approximately 1 month following the procedure, the patient returned with similar symptoms. Catheter angiography demonstrated 70% and 50% stenosis just distal and proximal to the stent construct, respectively. Rapid disease progression and non-atherosclerotic vasculopathy may argue against endovascular therapy.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
