Mapper Plus

Mapper Plus, the newest of the Registry Plus applications, is an application that has been developed to view and work with HL7 files and messages. Mapper Plus is collaboratively developed by participants in the NPCR–Modeling Electronic Reporting Project's ePath Pilot Project and programmed by the Registry Plus Development Team.

The program includes functions to import HL7 files manually or directly from the PHIN MS queue, test messages for existence of required data items, parse HL7 messages, and map HL7 data elements to NAACCR data elements. Mapper Plus also builds a pathology lab database, storing various HL7 data elements as discrete field values into tables in the database. The program creates NAACCR formatted abstract records from pathology reports during import into the pathology lab database. The program searches a terms table to find potential report of cancer, and the negation terms finder algorithm (NegEx) has been built to enhance the program's text mining capabilities in terms of specificity. Mapper Plus provides a screen to view pathology report text and a generated abstract side-by-side to allow coding of primary site and histology; it allows users to override any automated decisions about reportability and coding. Further development has been planned to suggest site and morphology codes to users as they work with pathology report-generated abstracts in this program.
