Nosocomial Infections in Combined Medical-Surgical Intensive Care Units in the United States

Abstract

Nosocomial infections in MS ICUs at the most frequent infection sites (bloodstream, urinary, and respiratory tract) almost always were associated with use of an invasive device. Device-associated infection rates were the best available comparative rates between combined MS ICUs, but the distribution of device-associated rates should be stratified by a hospital's major teaching affiliation status.

Risk factors for late-onset health care–associated bloodstream infections in patients in neonatal intensive care units

“…It is likely that more severely ill neonates required the use of both a ventilator and a catheter, but unmeasured factors such as preexisting colonization of the respiratory tract with potential pathogens may have increased the risk for CR BSI, as has been noted for candidemia. 24,25 In this study population, CR BSI were more likely than non-CR BSI to be caused by grampositive than gram-negative organisms. Gram-positive skin flora may be more likely to colonize the catheter during catheter insertion and use, whereas infections with gram-negative organisms may be more commonly associated with translocation of flora from the gut or respiratory or urinary tract.…”

Staphylococcus aureus Screening and Decolonization in Orthopaedic Surgery and Reduction of Surgical Site Infections

“…It is also one of the most common causes of infections in patients in intensive care [44,53], with nosocomial bloodstream infections [37], and with healthcare-associated pneumonia [35,50]. S. aureus is a Gram-positive aerobic bacteria often found in normal skin flora [31].…”

Catheter –Associated Urinary Tract Infection, Management, And Preventions

“…15.0% for P.aeruginosa 9.5% and 24.4% for MRSA [13]. Bacteriuria in long -term catheterized patients is usually polymicribial and, in addition to the pathogens seen in short-term catheterized patients.…”
