Eliminating Rework Through Utilization of Interfacing Automated Staining Platforms

The Leica Biosystems Customer Education Team had the opportunity to partner with an Anatomic Pathology laboratory to investigate the benefit of an interface for an Immunohistochemical staining instrument. This laboratory uses multiple Laboratory Information Systems (LIS), but only one system interfaces with the IHC stainer. An order placed in the interfaced LIS automatically transfers to the IHC staining instrument. The histotechnologist can easily search through the IHC stainer controller, find the stain order for the specific slide, and print the label. For the non-interfaced LIS, after placing the order in the LIS, the histotechnologist must enter the case accession number, block ID, and patient name and select the stain to be run manually. After entering the information into the IHC stainer controller, the histotechnologist can print the label. During a multiple-day observation period, the Leica Biosystems Customer Education Team performed time and motion studies to collect data for each LIS process. The goal was to provide a side-by-side comparison of the required time to prepare staining labels for the interfaced LIS and the non-interfaced LIS.

The chart shows both times, in seconds, by case, and by slide, to offer an accurate comparison. The manual process is faster when entering multiple stain orders for specific cases since not all information needs to be entered for each stain. The case accession number, patient name, and sometimes the block ID could remain the same for multiple stain entries. The average number of stains per case was 2.4 for the observation period at this laboratory.

Analyzing the average differences in time by stain, or slide, for the interfaced and the non-interfaced LIS, the team found that, for this laboratory, the histotechnologists spend 3.8 times longer preparing the staining labels for non-interfaced LIS stain orders as they do for interfaced LIS stain orders. This laboratory performs 48,000 IHC slides annually with the non-interfaced LIS; that time difference equates to 161.3 hours of histotechnologists time. That means the histotechnologists spend over one month annually preparing the staining labels.

For this Anatomic Pathology laboratory and similar laboratories not utilizing interfaces for their staining platforms, there are time savings available by removing rework and duplicate data entry. Although this study focused on time savings, anytime data entry steps are added to a process; there is an inherent risk of data entry errors. Eliminating those possible errors is another benefit of utilizing LIS interfaces for automated staining platforms.
