The limited connectivity in the pathology lab today between instrumentation, laboratory information system (LIS) and hospital information system (HIS) challenges the implementation of workflow solutions in the pathology laboratory. Workflow addresses the turn around time and the quality of diagnosis. Very few anatomical pathology laboratories use simple barcodes to identify samples. Secondly most instruments are not connected and multiple data entries add time and opportunities for errors.
Technology:
Dako Link is the back bone for the connection between the different systems and allows the use of barcodes for the sample. One example is an IHC stainer (Autostainer Link) connected to Dako Link. The imaging system (Dako ACIS III) is also connected to Dako Link, so no duplicate data entry is necessary, and no selection of a specific imaging application is necessary. The sample information moves seamless through the system (using the barcode). A Virtual Slide Viewer (EyeShare Pro) makes the digital slide available to anybody who can connect to the system through the hospital network.`
Design:
The workflow concept starts with the connection to the LIS system to acquire information on the slide. The bar code labels are used to identify the specimen throughout the process. The automated staining of the slides guarantees high quality and consistent staining that will allow the best possible results. Imaging applications optimized for the predefined staining protocols make the quantification of IHC slides (like Her2, ER, PR) reproducible. Using a workstation in the pathologists office allows the integration of all applications on one computer. Access to the staining status, analyze slides and report imaging results in the pathologists office improve the workflow in the pathology lab.
Results:
Implementation pilots connecting LIS, staining equipment and imaging system have shown that the improved workflow reduced the turn around time by eliminating the need to reenter the data multiple times in different parts of the process. Additionally a reduced error rate is achieved by the use of a positive ID throughout the process.
Conclusion:
Digital workflow in the pathology lab in combination with digital imaging will change the work in a pathology lab. All information can be accessible at one workstation, information is always linked to the correct patient, and quantification makes the results for IHC more reproducible.
