Lysis-Centrifugation Blood Culture TechniqueClinical Impact in Staphylococcus aureus Bacteremia

Arch Intern Med. 1986;146(12):2341-2343. doi:10.1001/archinte.1986.00360240055010
Abstract

• To determine the clinical impact of enhanced detection of Staphylococcus aureus by a lysis-centrifugation (LC) blood culture system, consecutive cases of S aureus bacteremia during a seven-month period were reviewed. Of 77 clinically significant cases, the LC system detected 70 cases (91%) while a conventional broth system detected 67 cases (87%). Of 60 cases detected by both systems, the LC system was positive earlier than the broth system by one or more days in 34 cases (57%) and later in none. It also detected more (12 vs four of 13) patients with persistent bacteremia who were receiving antimicrobial treatment. Forty-three patients (56%) did not receive appropriate antimicrobial therapy until cultures were reported positive. Enhanced detection of S aureus bacteremia is a clinically important advantage of the LC blood culture technique.
