April 14, 2008 HemaTrax Software Alert: HemaTrax Print Server & HemaTrax Standalone

1. Granulocyte and Granulocyte Platelet Search Error

Problem Reported:
A customer reported that when using HemaTrax Standalone Version 6.2 to search for products in the Granulocyte/Platelet product class that the program returned a list of Granulocyte products instead. Conversely, a search for Granulocyte products returned a list of Granulocyte/Platelet products.

Scope of Problem:
Testing at Digi-Trax reproduced this problem in the Standalone program Version 6.2. Further testing determined that the problem exists in the HTClient program that ships with the print server beginning with Version 3.0.

Identified Cause:
The cause of the problem has been isolated to the file named "CompDef.txt". This file populates the combination list selection boxes displayed in the search windows.

Solution:
Two lines in the "CompDef.txt" text file, located in the application program's directory, can be identified and the code numbers edited with the MS Windows NotePad editor to read as follows:

Granulocytes = 4
Granulocytes/Platelets = 3

Two patches, one for the HemaTrax Standalone and the other for the HemaTrax Print Server, will be released in the next few weeks. Installing the patches will correct this file in the appropriate target application.

2. Apheresis FFP|ACD-A/xx/>=-18C Search Failure

Problem Reported:
A customer reported that when a product search was done with "Fresh Frozen Plasma", "Apheresis", "ACD-A", "-18 C or colder" product characteristics specified, that the HemaTrax Standalone program would hang or freeze.

Scope of Problem:
Testing at Digi-Trax reproduced this problem in the Standalone program Version 6.2. Further testing determined that the problem manifests itself in a different way in the HemaTrax Print Server, Version 3.0.1 and the print server with the Version 3.0.2 patch applied. A search using the HTClient program for the same product characteristics doesn't return anything. This problem only occurs when searching based on product characteristics and does NOT occur when looking up products based on the ICCBBA product code.

Identified Cause:
This issue has been traced to the Digi-Trax Indexed Sequential Access Method (DTiSAM) dynamically linked library Version 3.0.1. The problem only occurs when looking up products using the HemaTrax weighted product code. That lookup method involves resolving indexes which specify duplicate keys. It also only occurs when a specific index boundary condition exists.

Solution:
The index searching function dealing with duplicate key indexes has been corrected and be available in DTiSAM, Version 3.0.2. Two patches, one for the HemaTrax Standalone and the other for the HemaTrax Print Server, will be released in the next few weeks. Installing the patches will correct this file in the appropriate target application.

3. Reconstituted Red Blood Cell Products in the HemaTrax product label database

Problem Reported:
A customer has reported that the HemaTrax product label database does not list any products as Reconstituted Red Blood Cells.

Scope of Problem:
This issue is true for all releases of the HemaTrax Print Server and Standalone applications with a product label database released before (April 14, 2008).

Identified Cause:
The logic of the program used by Digi-Trax to read and convert the ICCBBA product tables into a labeling database does not identify the characteristics and thus rename these products. This issue with the product and label design was worked on only relatively recently (last six months) by members of the Americas Technical Advisory Group and the ICCBBA Technical Director.

Solution:
The product label generator program is currently in the process of being modified to better handle changes such as this. The database will be generated and made available of update. Two patches, one for the HemaTrax Standalone and the other for the HemaTrax Print Server, will be released in the next few weeks. Installing the patches will correct this file in the appropriate target application.

In the interim time customers may use the product label maintenance functions available in the Print Server (HTClient.exe) and the Standalone application to edit the product name.

HemaTrax Standalone "AUTOLOGOUS DONOR" print option issue

Problem Reported:
A customer has reported that having set the option to print the phrase "AUTOLOGOUS DONOR" at the bottom of quadrant 1 (upper left) of the full face label. That the next day when they tried to print a full face label for an autologous collection that "VOLUNTEER DONOR" printed instead.

Scope of Problem:
This problem was duplicated by Digi-Trax in the HemaTrax Standalone, Version 6.2 release.

Identified Cause:
It was determined that on HemaTrax Standalone startup that the flag that determines whether or not to use this printing option was not being set properly. It was further determined that the flag does get set by just visiting the "Options" window available from the "Setup" pull-down menu.

Solution:
The HemaTrax Standalone application function that handles the internal setting of options flags at program startup has been corrected. A patch for the HemaTrax Standalone will be released in the next few weeks.
