Evaluation of the Q score and Q234 systems for cost-effective and clinically relevant interpretation of wound cultures

J Clin Microbiol. 2006 May;44(5):1869-72. doi: 10.1128/JCM.44.5.1869-1872.2006.


The Q score and Q234 systems were compared to our current protocol for interpreting wound cultures. The Q score and Q234 systems were more cost effective than our current method, with the Q234 system being considered the most useful protocol for implementation by both the laboratory and our clinicians.
