IDWeek 2018 - San Francisco, CA 

IDWeek 2018IDWeek 2018IDWeek 2018







RUMC/CCH ID had great representation at IDWeek 2018, the premier international scientific conference for ID specialists held this year in the beautiful city of San Francisco, CA (October 3-7). All second year ID fellows and approximately 20 current faculty members attended the conference. Many former fellows and faculty members joined us for a fantastic meal (e.g. Paella!) and drinks at our annual IDWeek RUMC/CCH ID reunion, which was held at Thirsty Bear Organic Brewery. Fellows and faculty presented several oral abstracts and posters on a variety of topics including infections with multi-drug resistant organisms in long-term care patients, the utility of a hospital approval pager for Clostridium difficile testing, the epidemiology of MRSA in the jail system, antimicrobial stewardship and the use of vancomycin, tools to improve HCV screening, and HIV therapy options and long-term cardiovascular outcomes. Faculty also spoke in various symposia, participated in “Meet-the-Professor” sessions, led poster rounds, and moderated scientific sessions. A few highlights are listed below. Special shout out to Teppei Shimasaki for being honored with the Robert C. Moellering Trainee Travel Award​, which is awarded to a fellow for excellence in the area of antibiotic resistance research, and to Kyle Popovich for being awarded the IDWeek Investigator Award!
