PLACE OF THIS DOCUMENT IN THE VIEN GUT DOSSIER
Document A.4 is the central reference document of the academic dossier of the Vien Gut Model. If A.0 establishes the overall architecture, A.1 establishes the EBM reference framework, A.2 identifies the three layers WHAT – HOW – DATA-to-operate, and A.3 confirms the global HOW gap through international evidence, then A.4 has the task of deploying in detail the full operational terminology of the model in a unified language that can be referenced, compared, and shared across all subsequent documents.
A.4 belongs to Tier 1 — Basic Architecture of the full dossier. It does not describe specific clinical processes like Part B, does not present each disease axis like Part C, and is not the place for dialogue–validation like Part D. The role of A.4 is to place all central terms of the model — from terms that already exist in the international literature to terms developed by Vien Gut out of practical experience — within a clear reference frame that is consistent, transparent in origin, and sufficiently precise in meaning so that international reviewers can read across the entire dossier without conceptual discontinuity.
READER GUIDE TO A.4
ABSTRACT
Document A.4 is the official operational dictionary of the Vien Gut Model. Every HOW term that appears in the dossier — from terms already established in international guidelines to terms developed by Vien Gut from real clinical operating needs — is compiled here using a single presentation structure: origin, operational definition, and international comparison or conceptual distinction.
A.4 does not seek to create a “private language” detached from the international literature. Its aim is the opposite: to clarify which terms Vien Gut uses exactly in their international sense; which terms are near equivalents or more concretely operationalized interpretations in the context of complex outpatient multimorbidity; and which terms were in fact developed by Vien Gut to name operational components for which the current literature does not yet provide sufficiently specific concepts.
A.4 is therefore a required document for correctly reading Parts B, C, and D.
