Discharge and referral data exchange using global standards--the SCIPHOX project in Germany

Area of Science:

• Health Informatics
• Computer Science

Background:

• Healthcare information systems, including Hospital Information Systems (HIS) and Physician Office Systems (POS), often lack standardized communication protocols.
• The need for interoperability is critical for efficient patient care and data management.

Purpose of the Study:

• To standardize information exchange between HIS and POS using XML.
• To implement the Clinical Document Architecture (CDA) as a backbone specification for healthcare data.
• To adapt the CDA for national use in Germany, focusing on discharge and referral letters.

Main Methods:

• Utilized the Extended Markup Language (XML) for data structuring.
• Adopted the Clinical Document Architecture (CDA), an ANSI-approved standard from Health Level Seven (HL7).
• Developed specifications for translating and interpreting CDA header tags within the German healthcare context.

Main Results:

• Established a framework for XML-based information exchange between HIS and POS.
• Successfully adapted the international CDA standard for German national requirements.
• Provided a solution for incorporating local data needs, such as insurance information, into the CDA structure.

Conclusions:

• The SCIPHOX project successfully demonstrated the feasibility of using CDA for standardized clinical information exchange in Germany.
• The developed specifications facilitate improved communication and data interoperability between different healthcare providers.
• This standardization supports more efficient healthcare processes and better patient data continuity.
