In this Hypothesis and Theory article we argue that the appropriate unit of health-AI evaluation is therefore not the model output alone, but the configured answer system - the large language model (LLM) together with source selection, retrieval, interface, action routing and downstream data return. We call this organizationally configured mode of mediation synthetic gatekeeping. Its necessary core comprises source selection and generative synthesis, with personalization and action routing as extending dimensions; its observable manifestations are content and pathway traces, and its proposed mechanism is infrastructural steering. Content parity does not guarantee pathway parity: two systems can name the same options while making only one easily actionable. Organizational position, revenue architecture and integration depth are treated as exposures that may shape these functions, not as elements of the construct, and owner-linked advantage is an empirical outcome to be demonstrated rather than assumed. Direct health evidence of owner- or revenue-linked steering remains sparse, and one comparative study found LLM answers less commercially biased than conventional search; the mechanisms nonetheless appear in adjacent domains, and health outputs are configurable at deployment level. We advance three core propositions - organizational alignment (P1), pathway asymmetry (P2) and behavioural mediation (P4) - with one conditional moderator hypothesis on conversion-linked funding (P3) and a measurement corollary on surface-pathway divergence (M1), each stated with its weakening condition. The framework yields a practical audit model based on configuration anchoring, paired content-pathway comparison, organizational disclosure and proportionate governance triggers. The unit of evaluation should move from the model output to the configured answer system in which information becomes action.</p>","PeriodicalId":73078,"journal":{"name":"Frontiers in digital health","volume":"8 ","pages":"1976313"},"PeriodicalIF":5.2,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13677928/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems promise to reach vulnerable groups more precisely than mass communication, and they rest on individual-level models of behaviour change. This article asks what happens to the concept of vulnerability once it becomes something such a system can read and act upon. It draws on the public health literature on vulnerability as a multilevel construct, the theory of fundamental causes, Rose's prevention paradox, and critical work on algorithmic systems and precision public health. On this basis it develops the Vulnerability Transformation Hypothesis. The article first distinguishes hyperindividualisation from the tailoring it intensifies. What is new is the inference of undeclared attributes, continuous re-profiling, open-ended generation, and operation at near-zero marginal cost per message. The hypothesis is stated as three claims of decreasing certainty. A near-analytic addressability claim holds that a system addressing users as individuals has only individual-level levers. A substantive and conditional re-encoding claim states that, for any system presenting itself as a means of reaching the vulnerable, the operationalised concept of vulnerability is reconstructed into a constellation of individual attributes. Structural information that enters an individual model returns as a predictor of personal risk rather than as a target of action. This transformation is representational rather than ontological, since the structural causes persist even as they recede from what the system can represent and change. A contingent displacement claim adds that, at the level of the field rather than the single system, the success of individualised tools may displace structural effort, a tendency documented as lifestyle drift. The article separates its claim from the precision public health debate and offers four falsifiable predictions. Among them is a discursive test of whether systems that invoke vulnerability then present individual tailoring as the means of addressing it. Such a pattern would evidence substitution of the concept, not mere inconsistency. The article illustrates the coding scheme across contrasting systems, so that others can test and revise the hypothesis.</p>","PeriodicalId":73078,"journal":{"name":"Frontiers in digital health","volume":"8 ","pages":"1956219"},"PeriodicalIF":5.2,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13672495/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In countries like Vietnam, dual-paradigm clinical guidelines actively mandate integrated treatments for high-prevalence chronic diseases. However, safe integration at the point of care is severely hindered by data fragmentation, profound epistemological differences, and a critical \"shadow pharmacovigilance\" crisis regarding underreported herb-drug interactions (HDIs). This paper analyzes the state-of-the-art of Artificial Intelligence (AI) in integrative healthcare and proposes the Integrative Medicine Knowledge Engine (IMKE), a novel architectural blueprint designed to safely bridge Vietnamese traditional medicine (VTM) and Western biomedicine. Shifting from siloed technical models to a clinical-first perspective, the IMKE conceptualizes a three-stage digital health pipeline: (1) advanced medical text mining to digitize unstructured traditional practitioner notes; (2) an Integrative Knowledge Graph (IKG) that maps holistic VTM diagnostic patterns to Western pharmacological databases and ICD-10 standards; and (3) an AI-driven Clinical Decision Support System (CDSS) for proactive HDI safety monitoring. We illustrate this architectural data flow through three clinical scenarios-Essential Hypertension, Type 2 Diabetes, and Rheumatoid Arthritis. These scenarios demonstrate the system's theoretical capacity to retrieve culturally appropriate treatments, identify cross-paradigm therapeutic synergies, and generate explainable, mechanistic safety alerts that augment physician judgment while mitigating clinical alert fatigue. Ultimately, the IMKE framework provides a scalable, culturally inclusive roadmap for digital health.
