POSITION OF THIS DOCUMENT WITHIN THE VIEN GUT MODEL ACADEMIC DOSSIER

Document B.2 is not a document about a single disease, nor is it a detailed protocol for one specific emergency scenario. B.2 is the central document of Part B — the Care Model, tasked with describing the architecture of the outpatient treatment plan over time in the Vien Gut Model. If B.1 answers the question of how the care system is activated during the first clinical encounter, then B.2 answers the next question: once the care system has been activated, how is the outpatient treatment plan organized to move the patient through the different stages of the treatment journey.

Within the multi-layered architecture of the dossier, B.2 belongs to Layer 1 — the Basic Architecture. It is built directly on the output data of B.1 while also serving as the foundation for B.3, B.4, and B.5. Without B.2, B.3 would struggle to determine in which phase the window of opportunity remains open; B.4 would lack a framework for allocating patient participation capacity over time; and B.5 would have difficulty embedding enabling conditions and priority principles into a structured operational journey. In other words, B.2 is the document that connects the logic of system activation in B.1 with the logic of sustaining the care system over time across the whole of Part B.

ABSTRACT

This document presents the Vien Gut outpatient treatment plan as a three-layer structure: WHAT consists of treatment targets and treatment principles benchmarked against the current guidelines for each disease axis; HOW is the clinical operational layer that organizes examination, diagnosis, risk stratification, multidisciplinary coordination, medication management, revisit cadence, and phase-transition mechanisms; DATA-to-operate is the minimum actionable dataset used to identify target-organ damage, disease spirals, the degree of decline, and the window of opportunity for treatment. On the basis of these three layers, B.2 organizes the treatment journey into four phases: acute stabilization, titration, maintenance, and target assessment. This is not a theoretical staging system, but the direct result of nearly two decades of integrated outpatient practice at Vien Gut, where patients with complex chronic multimorbidity cannot be treated safely through a static, linear, or cross-sectional plan.

B.2 further affirms that high-level treatment targets such as crystal-free status, dialysis deferral, prevention of heart-failure decompensation, and hepatic recompensation cannot be pursued by mechanically adding together single-disease guidelines. For these targets to become feasible in outpatient practice, the treatment plan must be organized as a dynamic architecture: it must know when to first control immediate risks, when conditions are sufficient for active titration, when monitoring cadence may be relaxed, when results should be maintained sustainably, and when the safety valve or reintegration after a disruption must be activated. B.2 is the document that describes this dynamic architecture.
