Autoposting Results with the VITEK® 2: Can We Afford Not To?


The VITEK® 2 uses technology that allows the clinical microbiology laboratory to rapidly report organism identification and susceptibility test results. However laboratories need to take advantage of this technology by reporting these results in a timely fashion. To minimize the turn-around-time (TAT) of identification and susceptibility test results, changes in workflow were initiated to put isolates int the VITEK 2 earlier and the results are autoposted to the LIS and in turn, the HIS, if deemed acceptable bythe advanced expert system (AES). This has lead to significant decreases in the TAT of reporting results and has allowed our clinicians instant access to this data. This has an obvious potential effecton patient care. In addition, these results will cause patients with multi-drug resistant organism (MDRO) to be isolated sooner decreasing the nosocomial spread of these organisms. This, in turn, has resulted in a dramatic decrease in our isolation of certain critical MDRO. Clinician awareness of this initiative is also critical to the success of this program.

At the conclusion of the program participants will be able to:

  • Recognize the importance of autoposting in the hospital's quality assurance and infection control programs.
  • Identify workflow issues that will approve TAT
  • Solve some of the problems associated with autoposting to the LIS
  • Evaluate the success of this initiative.
