SOPT - Source of Payment Typology

Overview

This vocabulary is defined by NAHDO as follows: “The Source of Payment Typology is a payer type standard that provides a mechanism for consistent reporting of payer data to public health agencies for health care services and research. [...] It was created by the former PHDSC Payer Typology Subcommittee and is now hosted by the National Association of Health Data Organizations (NAHDO).”

This vocabulary previously was called PHDSC and has now been renamed to its proper name. All existing concepts have retained their original concept ID.

Sources

The source data is provided by NAHDO in PDF format. The PDF format has to be extracted and converted into a csv file to be uploaded as a vocabulary.

Transformation

The procedures for transforming Concepts from the source to the OMOP Standard Vocabularies can be found on the OHDSI GitHub.

Concept Names

All Concepts are assigned the Full Source Name whereas the Short Description is stored as a Synonym. Concept_names are modified according to the source concept’s hierarchy in order to avoid unclear/ambiguous terms.

Concept Code

Concept codes are taken from the "Code" column.

Standard Concepts

• The Standard Concept flag has been set manually for all eligible concepts.
• Non-Standard concepts are either a negation, too unspecific (“other”) or invalidated by the source.

Domains

The concepts are all in the “Payer” domain.

Concept Classes

The concepts are all in the “Payer” Concept Class.

Concept Relationships

Internal Relationships for parent-child nodes are represented as “Is a” / ”Subsumes” relationships.

Hierarchy

SOPT concepts have no outside relationships and therefore appear in the hierarchy of the CONCEPT_ANCESTOR table only with its internal relationships.

Instructions for ETL

SOPT concepts are simple appropriate targets for payer information in the source datasets.

If you have previously referenced to the vocabulary_id “PHDSC” in your extraction logic, please replace this reference with “SOPT”.
