Abstract

The objective of this study was to evaluate the analytic performance characteristics of and user satisfaction with the new Roche OMNI S critical care analyzer in a clinical setting. Fourteen sites were included in this multicenter study, and each site performed from 100 to 300 measurements on the Roche OMNI S instrument. In method comparison experiments, all results with Roche OMNI S were in good agreement with the routine laboratory or other point-of-care methods. Correlation coefficients were above 0.94 for most parameters and above 0.98 for PO2PCO2and pH. Day-to-day imprecision using fresh blood samples showed good results, means of cviwere equal or below 0.7% for electrolytes, pH, and SO2; and were between 0.8% and 3% for the other parameters. In tonometry experiments, the recovery of the calculated PO2value was within ±2% and within ±3% for PCO2. The authors found a high degree of user satisfaction. Sample application/measurement, ease of use, routine maintenance, and quality control were highlighted by the users. Overall, the Roche OMNI S critical care analyzer showed a convincing analytic performance in imprecision testing, tonometry, and method comparison experiments. Thus, its use in critical care or point-of-care testing is recommended. The availability of total bilirubin determination with short turnaround time and very low sample volume may be beneficial to improve patient care in neonatology.
