Study finds multidrug-resistant gram-negative bacteria high in long-term care
Date:4/10/2009

tended requirements for contact precautions to MDRGN.

Using more than 1,660 clinical cultures (urine, blood and wound specimens) obtained from residents at a large, urban long-term care facility, the researchers found 180 cases of MDRGN compared to 104 cases of MRSA and 11 cases of VRE. Of further concern, they say, was the steady rise in MDRGN over the two-year study period, which increased from 7 percent the first year to 13 percent in the last year.

Dr. O'Fallon says that infections caused by MDRGN are associated with higher mortality rates, longer hospital stays, and increased costs compared with infections caused by gram-negative bacterial infections that can be treated effectively with antibiotics. Risk factors for MDRGN infection in the long-term care population include pressure ulcers, poor functional status, advanced dementia, and antimicrobial exposure.
