Enhancing workflow with Siemens ADVIA Centaur XP system

Healthcare News | 2012-01-23

The ADVIA Centaur XP is fully automated.

Efficiency, accuracy, and reliability were all attributes that Microbiology Supervisor Marcia Morgan and her colleagues at St. Mary’s Medical Center in Evansville, IN, U.S., were looking for in a new immunoassay system. After thoroughly comparing analyzers and visiting hospitals throughout their region, Morgan selected the Siemens ADVIA Centaur® XP Immunoassay System to automate HIV and hepatitis testing for the 300-bed hospital.

“Strong advantages”

Since St. Mary’s core laboratory uses an analyzer that does not offer hepatitis testing, the microbiology laboratory performs hepatitis and HIV testing for the hospital. To maximize efficiency, Morgan needed a system that could automate both tests. “There were a number of features that we thought were strong advantages for the Centaur,” Morgan says. Buffers and reagents for the ADVIA Centaur XP system are ready to use, she notes, while other systems required that they be reconstituted. The availability of local service technicians was appealing, Morgan adds, and the ADVIA Centaur XP system’s small footprint would allow it to integrate easily into their existing space. The ADVIA Centaur XP system uses disposable pipette tips, which reduces the risk of sample-to-sample carryover and eliminates the need to wash the sample probes. In addition, the system has a throughput of up to 240 tests per hour to easily accommodate hospital’s workload.
Before finalizing the decision, Morgan and staff visited two nearby hospitals that use the ADVIA Centaur XP system. She saw firsthand how easy it was to load samples and to add buffers and reagents. The hospitals also shared their quality control records, which

Dramatic improvements

St. Mary’s installed its ADVIA Centaur XP system in March 2011, and Morgan credits it with dramatically improving the efficiency and accuracy of HIV testing at the hospital. Whereas the manual system they previously used took up to three hours from sample preparation to result, the ADVIA Centaur XP system provides results in approximately 45 minutes, Morgan says. The ease of use that other hospitals spoke of during the site visits quickly became apparent. The 360-degree status light, which displays system information using simple color codes, is visible from anywhere in the lab and allows staff to quickly respond to any system issues. The high-resolution touch screen is intuitive and simplifies the execution of tasks. Samples and reagents can be added or removed at any time, even while the system is running, which further enhances productivity. Morgan says the addition of the ADVIA Centaur XP system and the efficiency it provides came at an ideal time for St. Mary’s. Demands on the laboratory have increased in recent years, and the hospital is even considering adding Siemens fully automated Vitamin D Total assay. “The lab is always changing,” Morgan says, “and the Centaur has helped us survive the increase in workload.”
