Now back to our original question: How do we get from human readable labeling to computer readable labeling? • SPL V2b Subgroup, Feb 2005
Now back to our original question: How do we get from human readable labeling to computer readable labeling without losing human readability? • SPL V2b Subgroup, Feb 2005
General Principles The Principles of Making Labeling Computer Readable • SPL V2b Subgroup, Feb 2005
General Principles It’s not that difficult. XML technology helps us do the trick: The electronic document contains both the human readable text and the computer readable structured content with codes. • SPL V2b Subgroup, Feb 2005
General Principles It’s not that difficult. XML technology helps us do the trick: The electronic document contains both the human readable text and the computer readable structured content with codes. Humans will see/print a neatly formatted text. Computers can find the codes and interpret them correctly. • SPL V2b Subgroup, Feb 2005
General Principles • XML technology and encoding allows us to “translate” the meaning and the logical structure of labeling content into a corresponding structured set of codes. This is achieved by • flagging (“tagging”) individual concepts (such a dizziness, hypotension, 40 mg) • assigning an information type to these concepts (e.g.: Is hypertension the indication, a contraindication, or an ADR?) • defining the “formal” and “logical” relationship between elements (Is common the frequency of rash or nausea? Is dizziness the cause of something or the consequence?), • and encoding the medical concepts (e.g. dizziness becomes 1234567890) • SPL V2b Subgroup, Feb 2005
General Principles • The SPL V2b Clinical Product Information Module provides the rules and tools for • tagging and assigning an information type to clinical concepts in a product label, • defining the formal and logical relationship between tagged elements, and • capturing the codes for the medical concepts. • It also allows us to define “wording elements” for the Highlights section, “connected to the corresponding full text paragraphs” and auto-displayed in the Highlights section. • SPL V2b Subgroup, Feb 2005

We are asked to review and helpimprove these rules and tools,as necessary. • SPL V2b Subgroup, Feb 2005
Clinical Product Information Module • The crux of the module is the excerpt, which “abstracts” or “elevates” content from the narrative and provides metadata about that content: • Electronically enables “Highlights” from the US Proposed New Labeling Rule – Federal Register, December 22, 2000; CFR 65(247):81082-81131 • Provides a machine-readable “flag” to product use content found in the narrative • Code systems ensure consistency in excerpt content and interoperability with other clinical decision-support systems (CDSS) • Defining this information (coding it unambiguously) in a consistent and machine-readable way enables controlled information management in CDSS • SPL V2b Subgroup, Feb 2005

Capturing Information Types and Relationships Assigning an Information Type to Individual Clinical Concepts and Maintaining their Relationship • SPL V2b Subgroup, Feb 2005
Capturing Information Types and Relationships • For humans, we use three mechanisms to tell physicians what to do and/or how to interpret information. • Calling certain conditions “names”, such as indication, contraindication, non-indication, ADR, interaction. • Providing explicit advice, e.g. “do monitor patients with XYZ for …”, “… carefully weigh the benefits and risks in patients with …” • Implying actions (not being explicit). It is usually not necessary to tell a physician to carefully weigh the benefits and risks in the presence of serious risks. They know to do that anyway. • SPL V2b Subgroup, Feb 2005

It is usually not necessary to tell a physician to carefully weigh the benefits and risks in the presence of serious risks.

Possible actions include: • Preventing a prescription unless overruled, or at least • Displaying information to physicians so that these can act. • SPL V2b Subgroup, Feb 2005
Capturing Information Types and Relationships As an important means of telling computers how to interpret labeling content, the SPL spec defines “classes” of information. These classes (sort of) tell a computer how to interpret content and, possibly, act. Clinical information needs to be put in those classes to become computer interpretable and actable. • SPL V2b Subgroup, Feb 2005
