7 The purpose of globally unique identification
7.1 SoC identification and data processing
When GSRN is used in data processing. solutions have been developed by IHE® International as Master Patient Indexes (MPI), which secure uniqueness of the identification in a defined environment and associates defined demographics to a SoC identifier. MPI should be interconnected by using IHE® tools so that heterogenic identifications are linked together by using the associated demographics. The use of GSRN, as described in this document, does not impact data processing and the use of Il-IE® tools, since IHE’s ®MPI are conceived to address situations where SoC are identified with any identifier.
GSRN are fixed length 18 digits numeric keys according GS1® General Specificationsl]. In a GS1® DataMatrix, the SoC GSRN shall be headed by a GS1® Al 8018.
7.2 Implementation challenges
Modern CIS require the use of a SoC identifier and an Individual Provider identification so that processes can be captured with scanning technologies. Some implementation challenges have been noticed, such as the following:
— Acceptance by Individual Provider: To prevent AIDC technologies consuming the Individual Provider’s time, it is important to associate these professionals to the implementation steps. including working ergonomic, graphic user interfaces, etc. A benefit of AIDC should be the reduction of administrative work (manual key entries in the nursing files, reordering of consumed products, etc.). Furthermore, it is important that any implementation requires scanning prior care processes, so that alerts are issued to prevent errors (scanning after care process would be too late to avoid error). Some processes require even two data captures: one prior to the care process (checking adequacy) and one after the care process (confirming end of process). An example for this double step is the administration of cytostaticsl3l.
— CIS data-field limitations: the length of the Individual Provider identification and the SoC identifier, when using GSRN, is 18 numeric digits. The optional SRIN for a SoC is a numeric field of up to 10 digits. The CIS is frequently not able to work with such data fields. It is important that healthcare providers and vendors collaborate to understand the value and the flexibility of the solution so that CIS support evolutions for the benefit of efficiencies (reducing manual key entries for documentation processes) and patient safety (combating workarounds[Sl,Il, checks ahead of care processes, etc.). It is recommended to add appropriate reference in the future call for tender. As an intermediary (temporary) solution, a middleware (e.g. in the form a web service) can be developed or found on the market, to link SoC’s GSRN, SRIN, as well as, Individual Provider identification (GSRN) to the existing CIS.ISO 18530 pdf download.
