Conference Highlights: IDWeek 2016

New research was presented at IDWeek 2016, the combined annual meeting of the Infectious Diseases Society of America, Society for Healthcare Epidemiology of America, HIV Medicine Association, and Pediatric Infectious Diseases Society, from October 26-30 in New Orleans. The features below highlight some of the studies presented at the conference. —————————————————————- Patient- and Environment-to-Nurse Pathogen Transmission Data are lacking on the transmission of pathogens to healthcare professionals from patients and patients’ environments. For a study, researchers obtained cultures from 40 nurses’ scrubs, 167 patients, and the patients’ rooms during three separate, 12-hour ICU shifts. All nurses used new scrubs for each shift. During these shifts 22 confirmed transmissions were observed, among which six were from patient to nurse, 6 were from environment to nurse, and 10 were from patient to environment. No nurse-to-patient or nurse-to-environment transmissions were observed. —————————————————————-   Outcomes With Rapid Microarray Testing An available gram-negative blood culture test is able to detect four gram-negative genera, four species, and six resistance genes within 2 hours of blood culture positivity. The impact of pairing this test with an antimicrobial stewardship intervention on antimicrobial and clinical outcomes has not been well defined. Study investigators compared patients admitted with a blood culture positive for a gram-negative organism during the 6 months before (pre group) and after (post group) use of this microarray test as part of an antimicrobial stewardship intervention. The number and type of antimicrobial switches were similar between the groups, as were in-hospital mortality rates. However, median time from gram stain to antimicrobial switch was significantly decreased in the post group. Median time to active therapy among patients...
