PURPOSE: Rapid detection of infection control targets is needed and several bacterial target assays are commercially available. Detection of patients colonized with Klebsiella pneumoniae carbapenemase-producing Enterobacteriaceae (KPC-CRE), methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) comprises an essential part of infection control programs. This study evaluated the performance and feasibility of a novel molecular-based diagnostic screening test, the NanoCHIP(®) Infection Control Panel (ICP) assay (Savyon Diagnostics, Israel), which enables simultaneous detection of KPC-CRE, MRSA and VRE directly from swab samples and compares its sensitivity and specificity to culture. METHODS: Prospective direct swab analysis of 338 (70 CRE, 198 MRSA and 70 VRE) screening swab samples. RESULTS: Including all targets and all valid samples, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the NanoCHIP(®) ICP assay were 91.1, 99.5, 99.1 and 94.9 %, respectively. CONCLUSIONS: As far as we know, this is the first report regarding a single molecular-based system that detects all three targets (CRE-KPC, MRSA and VRE) simultaneously, directly from swab samples, using the same reaction and platform. Overall, the assay was easy to perform, enabling medium- to high-throughput screening. Same day results enable efficient infection control interventions, such as carrier isolation.
