PLACE OF THIS DOCUMENT IN THE VIEN GUT DOSSIER
A.3 is not a workflow paper, not a single-disease application paper, and not a paper about organ-target clinical outcomes. Its job is different: it brings international evidence to support an argument prepared by A.1 and A.2 – that the HOW gap in care for complex chronic multimorbidity is not a local impression at Vien Gut, but a real global, structural gap already recognized in guidelines, international consensus documents, and independent studies.
A.3 belongs to Layer 1 – Core architecture. A.1 shows the structural break in the EBM chain at the point of clinical application. A.2 defines WHAT, HOW, and DATA-to-operate as the architecture used to fill that gap. A.3 then adds the international evidence showing that the gap truly exists at a global scale. Only after A.3 does the reader have a strong enough foundation to move into A.4-A.5, Part B, Part C, and Part D without misunderstanding the Vien Gut Model as only a local experience.
READER GUIDE TO A.3
- To understand the overall architectural statement of the full dossier, read A.0.
- To understand the EBM reference framework and the structural break in the EBM chain, read A.1.
- To understand the precise definitions of the three layers WHAT – HOW – DATA-to-operate, read A.2.
- To understand the detailed operational terminology, read A.4.
- To understand the standardized terminology table, read A.5.
- To see how the Vien Gut Model transforms HOW into operational processes, read B.1–B.5.
- To see how this framework is applied to each disease axis, read C.1–C.n.
- To see how the HOW gap is carried into academic dialogue and multicenter validation, read Part D.
ABSTRACT
A.3 presents international evidence confirming that the HOW gap in care for complex chronic multimorbidity is a global problem. The main message is this: modern medicine has built the WHAT layer very strongly through single-disease guidelines, and the international community has also begun to recognize the limits of the single-disease model in patients with multimorbidity. But after recognizing the gap, the world still has not produced a HOW + DATA-to-operate architecture that is concrete enough, structured enough, operational enough, and transferable enough for complex multimorbidity in outpatient care. A.3 gathers three kinds of evidence: the global scale of complex chronic multimorbidity; the lack of HOW in single-disease guidelines and multimorbidity consensus documents; and the measurable clinical harm caused by fragmented care.
From that base, A.3 defines four structural features of the global HOW gap and clarifies the academic position of the Vien Gut Model: it does not replace the WHAT layer of guidelines; it adds HOW and DATA-to-operate so guideline WHAT can work in integrated, personalized, and verifiable outpatient care.
