    Clinical comparison and agreement of PCR, antigen, and viral culture for the diagnosis of COVID-19: Clinical Agreement Between Diagnostics for COVID19
    (Elsevier, 2022) Agard, Amanda; Elsheikh, Omar; Bell, Drew; Relich, Ryan F.; Schmitt, Bryan H.; Sadowski, Josh; Fadel, William; Webb, Douglas H.; Dbeibo, Lana; Kelley, Kristen; Carozza, Mariel; Lei, Guang-Shen; Calkins, Paul; Beeler, Cole; Medicine, School of Medicine
    The aim of this study is to compare the COVID-19 nasopharyngeal PCR (NP PCR) to antigen, nasal PCR, and viral culture. One-hundred-and-fourteen risk-stratified patients were tested by culture, nasal PCR, NP PCR, and Ag testing. Twenty (48%) of the high risk and 23 (32%) of the low risk were NP PCR positive. Compared with NP PCR, the sensitivity of nasal PCR, Sofia Ag, BinaxNOW Ag, and culture were 44%, 31%, 37%, and 15%. In the high risk group, the sensitivity of these tests improved to 71%, 37%, 50%, and 22%. Agreement between tests was highest between nasal PCR and both antigen tests. Patients who were NP PCR positive but antigen negative were more likely to have remote prior COVID-19 infection (p<0.01). Nasal PCR and antigen positive patients were more likely to have symptoms (p = 0.01).

    Strategies for the successful implementation of disinfecting port protectors to reduce CLABSI in a large tertiary care teaching hospital
    (Elsevier, 2019-12) Beeler, Cole; Kerley, Denise; Davis, Carmen; Hazen, Dana; Snyderman, William; Lyons, Kathy; Sadowski, Josh; Sweeney, Jennifer; Dbeibo, Lana; Kelley, Kristen; Webb, Douglas H.; Medicine, School of Medicine
    Disinfecting port protectors are a supplement to the central line–associated bloodstream infection prevention bundle as an optional recommendation from the Centers for Disease Control and Prevention. Despite evidence of effectiveness, few centers have successfully reported systematic, sustained implementation of these devices. In this article, we discuss a successful implementation in a large tertiary care teaching hospital, using an evidence-based, multidisciplinary approach.
