Exchanging care records using HL7 V3 care provision messages.

Area of Science:

• Health Informatics
• Healthcare Standards Development

Background:

• The HL7 V.3 Care Provision Domain messages offer an alternative to the HL7 Clinical Document Architecture (CDA).
• These messages enable human-to-human and system-to-system structured data exchange, crucial for continuity of care.
• They support interactive data exchange through querying capabilities.

Purpose of the Study:

• To describe the Health Level 7 (HL7) V.3 Care Transfer, Care Record Query, and Care Record messages.
• To highlight the significance of the Care Provision Domain within the HL7 standard.
• To present an American National Standards Institute (ANSI)-approved HL7 standard.

Main Methods:

• Development based on international use cases and information analysis.
• Application of HL7 consensus methods, including working group meetings and balloting.
• Inclusion of pilot implementations and subsequent evaluation for refinement.

Main Results:

• The Care Provision Domain Model was refined through feedback from membership and pilot implementers.
• The model was accepted as a normative, ANSI-approved standard after a formal ballot process.
• The model defines the structure and dynamics of Care Record, Care Record Query, and Care Transfer messages.

Conclusions:

• The HL7 V3 Care Provision Domain supports care dynamics and continuity through interactions and queries, differentiating it from HL7 CDA.
• It shares similarities with HL7 CDA in terms of data organization and structure.
• This standard enhances structured data exchange for improved healthcare coordination.
