No other organisms isolated definition
No other organisms isolated means there is not isolation in a blood culture of another recognized pathogen (e.g., S. aureus) or common commensal (e.g., coagulase-negative staphylococci) other than listed in MBI-LCBI criterion 1, 2 or 3 that would otherwise meet LCBI criteria. If this occurs, the infection should not be classified as MBI-LCBI.9. Grade III/IV GI GVHD is defined as follows:• In adults: ≥1 L diarrhea/day or ileus with abdominal pain• In pediatric patients: ≥20 cc/kg/day of diarrhea REPORTING INSTRUCTIONS 1. Report organisms cultured from blood as BSI–LCBI when no other site of infection is evident (see Appendix 1. Secondary Bloodstream Infection (BSI) Guide).2. Catheter tip cultures are not used to determine whether a patient has a primary BSI.3. When there is a positive blood culture and clinical signs or symptoms of localized infection at a vascular access site, but no other infection can be found, the infection is considered a primary BSI.4. Purulent phlebitis confirmed with a positive semiquantitative culture of a catheter tip, but with either negative or no blood culture is considered a CVS- VASC, not a BSI or an SST-SKIN or ST infection.5. Occasionally a patient with both peripheral and central IV lines develops a primary bloodstream infection (LCBI) that can clearly be attributed to the peripheral line (e.g., pus at the insertion site and matching pathogen from pus and blood). In this situation, enter “Central Line = No” in the NHSN application. You should, however, include the patient’s central line days in the summary denominator count.6. If your state or facility requires that you report healthcare-associated BSIs that are not central line-associated, enter “Central Line = No” in the NHSN application when reporting these BSIs. You should, however, include all of the patient’s central line days in the summary denominator count.
