ARTERIA — technical proposal (public version)

About this version: this is the ARTERIA technical document in its public version for guild, academic, legal, and citizen scrutiny. The conceptual architecture, institutional governance, normative framework, schedule, resources, success metrics, and operational transparency are articulated in full. The specific technical implementation detail (complete data schemas, algorithms, deployment sequences) is documented in a repository under control of the Foundation of the Standard (§10), accessible for qualified technical audit under agreement. The institutional rationale for this balance is explicitly articulated in §3 and §6.5: maximum institutional transparency + structural protection against reimplementation with hidden capabilities.

Published by: Observamed STAR Foundation, backed by twelve years of joint guild work with Dr. Sergio Isaza Villa (Former President of the Colombian Medical Federation) and the architecture and legal articulation technical team.

Health that flows, life that arrives — to the patient, without obstructions, without delays.

Executive summary

The Colombian health system faces a structural financial crisis documented by national authorities and sector guilds. The Comptroller General of the Republic has open fiscal liability proceedings of approximately $11 trillion COP between 2022 and 2025 linked to the health sector. The system closed 2025 with operational losses of $7.3 trillion COP. AFIDRO reports a structural accumulated deficit of approximately $30 trillion COP as of December 2025, projected at $37 trillion for 2026. The system's current debt to the pharmaceutical industry amounts to $4.42 trillion COP (AFIDRO March 2026), with nearly $1.6 trillion past due. The Colombian Association of Hospitals and Clinics (ACHC) reports that receivables more than 90 days past due reach 58% of the total owed to IPS (health providers), totaling $25.7 trillion COP as of December 2025.

The visible consequence to the citizen: significant delays in appointment scheduling (weeks to months according to the Ombudsman 2024), medications that do not reach the patient due to the breakdown of the financial flow between intermediary insurance and laboratories, health professionals under institutional pressure without complete legal protection of their clinical acts, and a documented volume of adverse drug events whose underreporting global pharmacovigilance literature estimates at ≥ 80% of real cases.

ARTERIA is the technical architecture that structurally closes these loss vectors. It is not yet another administrative regulation proposal over the current model. It is the national technical platform that replaces the current operational fragmentation with a single articulated platform with cryptographically verifiable public traceability, technical identity of the patient and the professional protected by post-quantum standards, a unified pharmaceutical registry open to the citizen, drug surveillance with automatic correlation of adverse events, a national clinical system for the health human talent, and complete technical sovereignty over national infrastructure without dependencies on foreign providers with capacity for political or financial pressure.

The proposal is compatible with the current legal framework during the transition phase (months 0-12). The structural reform materializes progressively between months 12-30, through regulatory decree and a specific bill of law for the transition of the per-affiliate capitation payment model (UPC, per-capita payment unit) toward per-event capitation payment (UPE, per-event payment unit) + the repeal and replacement of a specific set of norms (Resolution 3100 of 2019, Decree 4747 of 2007 modified by Decree 441 of 2022, Resolution 3047 of 2008, MIPRES instruments) that sustain the current insurer-centric model.

ARTERIA positions itself as an operational accelerator of the 2025-2035 horizon declared by current public policy, not as a substitute: it materializes the three axes of the National Health Quality Policy (Res. 1058/2026), the five pillars of the Preventive Predictive and Resolutive Model (Decree 858/2025), the six strategic lines of the Public Policy on Health Human Talent (Res. 1444/2025), the seven primary care quality attributes (Res. 2696/2024), and the commitments of the National Rural Health Plan (Decree 351/2025) — all today at the declarative level. ARTERIA delivers executable architecture from day one. Formal alignment mapping is articulated in §13.

The required investment is marginal compared to projected financial recovery. Modernization is self-financing with a fraction of the flow currently captured by operational fragmentation + the structural losses documented annually.

ARTERIA: life arrives.

§1. Operational diagnosis of the current system

1.1. Fragmentation as capture vector

The regulatory-operational ecosystem of the Colombian health system today operates in non-articulated silos, each with a documented institutional capture vector:

The structural pattern: each silo operates with its own database, its own protocol, its own normative regime. There is no point-to-point traceability between resource origin → authorization → care → dispensing → adverse event → reporting → regulation. Opacity and fragmentation are the capture vector — corruption does not operate against the systems; it operates in the gaps between systems, where no one has visibility or accountability.

1.2. The perverse incentives of the per-affiliate capitation model

The UPC (per-capita payment unit) is delivered to the EPS per enrolled affiliate, regardless of whether the affiliate receives care or not. The mathematical consequence: the EPS maximizes income by minimizing effective care. Each delay, each administrative denial, each rejected authorization, each bureaucratic barrier the affiliate encounters is operational benefit for the EPS. The system economically rewards non-compliance with the insurer function.

This is not a failure of individual operators — it is a structural property of the per-affiliate capitation model. No subsequent administrative control effort corrects an inverted-sign incentive. The only structural solution is to invert the incentive: reorient the payment flow from "the affiliate exists" toward "the event was attended and confirmed".

1.3. The opacity of the UPC flow + the 120 × 120 × 60-70 capture mechanism

The current flow of the health peso transits through a sequence that combines operational silence with administrative discretion:

Citizen contribution + State contributions
         ↓
   ADRES (collection + compensation)
         ↓
   UPC payment to EPS per enrolled affiliate
         ↓
   EPS (risk administration, without transparency)
         ↓
   Payment to IPS for contracted services (restricted network)
         ↓
   IPS attends (with delays + intermediate authorizations)
         ↓
   Dispenser delivers medication (when there is flow)
         ↓
   Patient receives (when everything above worked)

Between each link there is a capture window: silence about why it is delayed, why it is denied, why a medication appears with one price in SISMED and another is billed to the system, why the provider network excludes obvious options for the patient. Reactive audit — the only one available today — operates years after the event, when recovering the damage is no longer possible.

The structural pattern of payment delay to providers

The legal framework (Law 1438 of 2011, article 13) establishes payment deadlines to providers: minimum advance of 50% of the contract value within 5 days of its signing and balance at 30 days. The legal review deadlines (Resolution 3047 of 2008, Annex 6) are: 20 business days for the EPS to flag the invoice, 15 days for the provider to respond, 10 days for the EPS to decide.

In practice documented by ACHC, these deadlines are rarely met. The operational pattern observed:

• Mass invoice flags are used as a pressure mechanism to extend effective payment terms
• Receivables more than 90 days past due reached 58% of the total owed to IPS as of December 2025, according to ACHC
• EPS → IPS debt totaled $25.7 trillion (ACHC Dec 2025) or $32.9 trillion (Comptroller General, including other actors)
• In EPS intervened by the government, effective flow toward IPS dropped to 37% in January 2025, compared to 48% in the fourth quarter of 2024 (Infobae / ACHC)
• Effective payment terms are substantially longer than legal terms, generating cycles where the provider ends up accepting discount negotiations not to lose more liquidity

The aggregate effect: a material portion of the system's financial flow is captured by delay between the entity responsible for payment (EPS) and the effective service provider (IPS). ARTERIA closes this vector structurally by paying directly from ADRES to the provider upon event confirmed in the national immutable registry, without the flow transiting through the intermediary's accounts.

1.4. The pharmaceutical crisis as symptom

The historical debt of the system to pharmaceutical laboratories amounts to $4.42 trillion COP (AFIDRO, March 2026), of which approximately $1.6 trillion (37%) are past due. Laboratories have consequently reduced supply to the channel, which manifests to the citizen as "there is no medication". The financial resource is not lacking — the flow from insurance to laboratory broke at some opaque point. Without public traceability, identifying exactly where the flow broke is impossible. Without identifying it, structurally repairing it is impossible.

ARTERIA structurally closes this vector.

1.5. Documented figures of the structural crisis

Verifiable data on the cost of fragmentation, with source:

ARTERIA: when the artery is obstructed, the tissue dies. The current system is dying distal to documentable obstructions. Repairing them is not optional.

§2. Structural thesis

2.1. Flow reorientation — ADRES pays directly, the EPS only nominates

ARTERIA operates on a single principle: the flow of the health peso goes to the confirmed care event, not to the intermediary that administers the list of affiliates.

The operational mechanism:

1. ADRES retains control of the financial flow. The EPS shifts from resource administrator to technical payment nominator: it tells ADRES "this provider should be paid for this event", and ADRES verifies the nomination against the event confirmed in the national immutable registry and pays the provider directly without the money passing through the EPS accounts.
2. The EPS receives an operational fraction of the UPC specifically allocated to its subordinate administrative function (support network, administrative management, patient communication). It does not receive or administer the payment flow to the provider.
3. If the EPS does not nominate a provider that effectively attended a confirmed event, the provider can appeal directly to ADRES, and the smart contract verifies against the DAG and releases the payment. The administrative obstruction is recorded and triggers a process before Supersalud.
4. If the EPS nominates fraudulently — events without real care — the DAG verification (which requires patient signature + professional signature + IPS signature) prevents the release. The attempt at fraudulent nomination is recorded and initiates disciplinary process.
5. Structural result: the 120 days → 120 days → 60-70% mechanism (described in §1.3) ceases to operate mathematically. The EPS cannot withhold payments that no longer transit through its accounts. The provider receives directly upon confirmed event within a deadline defined by smart contract (≤ 30 days).

This does not require dissolving the EPS by decree. It requires removing from them the structural function that allowed capture. EPS that contribute real value (quality administrative management, patient support, provider networks) survive as subordinate logistical operators under verifiable pay-per-service. Those that only captured in the opaque flow cease operations due to natural economic unviability.

2.2. Traceability as a structural property

Every flow in ARTERIA is cryptographically verifiable and publicly auditable without exposing the patient's personal data:

• Every UPC peso has verifiable origin, route, and destination down to its last partition
• Every clinical act is signed by the technical identity of whoever executed it
• Every medication has chain of custody from manufacturer to dispensing, by batch and dose
• Every regulatory decision (authorization, batch withdrawal, CNPM price adjustment) is executed as an auditable smart contract
• Every EPS payment nomination to ADRES is recorded and auditable

The citizen can consult in real time where their resource is, what service corresponds to them, what medications are authorized at what price, without asking permission of any intermediary.

2.3. Competitive state logistics operator — structural presence without monopoly

ARTERIA operates with the guarantee of a competitive state logistics operator in the pharmaceutical dispensing chain and associated logistical services. This is NOT state monopoly of health, nor nationalization of the pharmaceutical chain. It is permanent structural presence of the State in the market in conditions of real competition with private operators.

Why it matters:

• The State maintains real logistical operation (not just regulation) across the entire national pharmaceutical chain
• It competes with private operators in market terms: if private operators offer better service or better price, the State loses market share and must improve
• If private operators attempt to capture the market (as already occurred with the national pharmaceutical chain in 2025), the State is always present with real operational capacity to substitute
• It functions as a quality and price benchmark: what the state operator does well puts competitive pressure on private operators, and vice versa
• In case of crisis (shortage, cartelization, external political pressure, armed conflict, pandemic), the state operator sustains coverage without depending on providers who may withdraw or pressure

Explicit limitation: the state operator does not receive unfair subsidies. It competes under real market conditions. Its existence operates as structural containment, not as replacement of the private sector.

2.4. National technical sovereignty

ARTERIA is built and operated on independent national technical infrastructure, without foreign licensing or dependencies on providers with capacity for political, financial, or regulatory pressure:

• Zero dependence on foreign cloud hyper-computation (Microsoft Azure, Amazon AWS, Google Cloud)
• Zero international licensing for the core components
• Code auditable by qualified technical teams under governance of the Foundation of the Standard (§10)
• Reproducible builds verifiable by independent auditors
• Servers physically in Colombian territory with dedicated encrypted backbone

Sovereignty is not ideological ornament. It is operational property: it means that no change of foreign government, no foreign regulatory decision, no international commercial incident can interrupt or degrade the functioning of the Colombian health system. The resource remains under national technical control, auditable by the State and by civil society.

2.2. Traceability as a structural property

Every flow in ARTERIA is cryptographically verifiable and publicly auditable without exposing the patient's personal data:

• Every UPC peso has verifiable origin, route, and destination down to its last partition
• Every clinical act is signed by the technical identity of whoever executed it
• Every medication has chain of custody from manufacturer to dispensing, by batch and dose
• Every regulatory decision (authorization, batch withdrawal, CNPM price adjustment) is executed as an auditable smart contract

The citizen can consult in real time where their resource is, what service corresponds to them, what medications are authorized at what price, without asking permission of any intermediary.

2.3. National technical sovereignty

ARTERIA is built and operated on independent national technical infrastructure, without foreign licensing or dependencies on providers with capacity for political, financial, or regulatory pressure:

• Zero dependence on foreign cloud hyper-computation (Microsoft Azure, Amazon AWS, Google Cloud)
• Zero international licensing for the core components
• Code auditable by qualified technical teams under governance of the Foundation of the Standard (§10)
• Reproducible builds verifiable by independent auditors
• Servers physically in Colombian territory with dedicated encrypted backbone

Sovereignty is not ideological ornament. It is operational property: it means that no change of foreign government, no foreign regulatory decision, no international commercial incident can interrupt or degrade the functioning of the Colombian health system. The resource remains under national technical control, auditable by the State and by civil society.

2.4. The ARTERIA architecture is articulated component by component — not an abstract technological proposal

The fundamental difference with any other proposal of digital transformation of the health sector that has been presented in Colombia is that ARTERIA is not a technical abstraction that needs to be imagined. It is a component-by-component articulated architecture, with identified technical primitives, with defined operational responsibilities, with documented relationships between each layer, and anchored in verifiable open standards. When a constitutionalist, an economist, a guild, or an association asks "how is it technically done?", ARTERIA has a concrete answer — not a statement of future intent.

2.4.1. Articulated architectural components

The ARTERIA architecture is articulated in nameable components with clear responsibilities and documented relationships:

2.4.2. Leveraging already-deployed national infrastructure

ARTERIA is articulated to leverage the already-deployed national telecommunications infrastructure without rebuilding it from scratch. This includes:

• Private network dedicated to the health sector — the clinical and financial data of the national health system do not transit through the public internet. Transmission operates over a private network with end-to-end encryption + additional protection by the defensive cryptographic layer. Minimal latency, full operational sovereignty, and sensitive information remains outside open internet traffic where it is susceptible to interception.

• Processing at mobile network edge nodes — the architecture leverages the edge computing infrastructure deployed or in active deployment at the edge nodes of the national mobile network. This enables geographically distributed low-latency processing, natural redundancy through the existing cellular topology, leveraging of investment in infrastructure already made by private mobile operators at industrial scale, and inherited territorial coverage.

• Inherited territorial coverage — mobile operators have already deployed coverage in much of the national territory, including rural areas subject to universal coverage plans. ARTERIA operates over that coverage. For areas without stable mobile coverage, the offline-first architecture (Appendix #09 §2) operates with synchronization upon contact when the itinerant team reaches a connected node.

• Sovereign commercial agreements — articulation with operators is made through formal commercial agreements of the Colombian State (via ADRES + MinTIC + Ministry of Health), with specific SLAs for the health sector, with a health data protection regime articulated in accordance with the statutory block (coverage Appendix #02), and with a State technical sovereignty clause (including the possibility of migration to another operator or to independent state infrastructure if conditions require it). Sovereignty is not compromised by leveraging private infrastructure — sovereignty lies in the control of data, standards, and the permanent technical capacity of the State.

2.4.3. Open standards + auditable code

Each component of the ARTERIA architecture is articulated on open standards verifiable by independent third parties:

• Open transport and connectivity standards (IETF)
• Auditable cryptographic standards with post-quantum backing
• International clinical interoperability standards (FHIR R5, SNOMED CT, LOINC, ICD-11)
• Mature open-source standards for data persistence and replication
• Build chains with reproducible builds verifiable bit-for-bit by independent auditors

The specific technical detail of each component — exact technology selections, protocol versions, interface schemas between layers, configuration keys — is documented in the technical repository under control of the Foundation of the Standard (§10), auditable by qualified technical teams under technical confidentiality agreement. The technical core code operates under a license that preserves auditability by the qualified technical community + the State, without capture by national or foreign private intellectual property, with institutional balance articulated in §3 to prevent reimplementation with hidden capabilities.

2.4.4. Operational and political implication

ARTERIA does NOT require faith in an architecture yet to be invented. The architecture is articulated in coherent components with clear responsibilities, each verifiable by qualified technical teams with open standard technology + auditable code under governance of the Foundation. Magistrates, legislative advisors, economists, and guilds can evaluate the proposal with the confidence that each technical piece is identified with its responsibilities, its interfaces, and its relationships with the other pieces — not as a black box nor as an abstract promise.

The difference from most failed Colombian government digitalization projects (PISIS, several iterations of SISPRO, UEHR with low partial implementation — coverage Appendix #07 + Appendix #12) is structural: those began as proposals without disaggregated technical architecture; ARTERIA begins with technical architecture articulated in nameable and verifiable components, with clear operational responsibilities, on auditable open standards, with governance that avoids capture by a single provider, and with leveraging of private infrastructure already deployed by national mobile operators (which drastically reduces implementation cost and territorial coverage timeline).

§3. ARTERIA architecture — functional layers

ARTERIA is built on seven vertically integrated functional layers. Each layer is modular, replaceable, auditable, and sustained by open standards of international adoption. The arterial metaphor operates literally: information and resource flow from the regulatory center toward the extremities — each patient, down to the last rural hamlet — without intermediate obstructions.

┌──────────────────────────────────────────────────────────────┐
│  Layer 7 — Public access + external audit                    │
├──────────────────────────────────────────────────────────────┤
│  Layer 6 — Patient client + national clinical system         │
├──────────────────────────────────────────────────────────────┤
│  Layer 5 — Unified national registry                         │
├──────────────────────────────────────────────────────────────┤
│  Layer 4 — Verifiable regulated logic (smart contracts)      │
├──────────────────────────────────────────────────────────────┤
│  Layer 3 — Immutable system event registry                   │
├──────────────────────────────────────────────────────────────┤
│  Layer 2 — Cryptographic identity of participants            │
├──────────────────────────────────────────────────────────────┤
│  Layer 1 — National distributed infrastructure               │
└──────────────────────────────────────────────────────────────┘

Layer 1 — National distributed infrastructure. Physical servers in Colombian territory (with international backup in case of regional disaster), dedicated encrypted backbone between nodes, transactional capacity with two orders of magnitude of headroom over the expected health system flow. Technical sovereignty: the system does not depend on foreign jurisdiction to operate.

Layer 2 — Cryptographic identity of participants. Each patient, health professional, provider, dispenser, and regulator operates with a hardware-bound cryptographic key pair generated on their device and never exportable. Cryptographic primitives with robust public audit and post-quantum backing. Authentication by complementary coherence covering the stolen device case.

Layer 3 — Immutable event registry. Each system event (clinical, pharmaceutical, regulatory, financial) is cryptographically signed and recorded in a distributed graph across validators. Confirmation under Byzantine fault tolerance consensus with seven structurally independent entities (patient, professional, IPS, standard operator, health authority, fiscal authority, independent external auditor). Mathematically verifiable immutability by any auditor without permission from the Ministry.

Layer 4 — Verifiable regulated logic. Norm-regulated system decisions are executed as publicly verifiable logic, without opaque administrative discretion: service authorization, medication dispensing, financial settlement upon confirmed event, application of price regulation, batch withdrawal due to adverse event, sanitary registry renewal. Rules are auditable code, not case-by-case interpretation. Explicit code governance under consensus of the seven entities + public comment window before deployment.

Layer 5 — Unified national registry. Structurally replaces the fragmentation of INVIMA + SISMED + MIPRES + ReTHUS under a single national master registry with canonical schema. Each pharmaceutical product has a single integrated entry (identification, international classification, pharmacological properties, stability, clinical information, economic-regulatory, academic content, regulatory history). Each professional has cryptographically verified credentials. Each institutional provider operates by accredited technical function, not by EPS network membership.

Layer 6 — Patient client + professional clinical system. The patient accesses via native mobile application that operates as cryptographic wallet + single service portal — with dynamic service assignment (not manual search), unified health record accessible only to the patient and to authorized IPS, telemedicine, one-tap ADR reporting. The professional operates via the national clinical system with interoperable health record, cryptographic signature of each act, authorization without intermediate procedure, integrated electronic prescription, explicit legal protection against adverse events.

Layer 7 — Public access + external audit. Open API for research and specialized press, real-time citizen dashboards, annual reports with cryptographic verification available to any independent auditor. Annual external audit is a structural property of the system, not an administrative concession.

Interoperability standards

ARTERIA operates on open standards of international adoption: FHIR R5 (HL7 International) as the clinical exchange layer interoperable with 31 countries, complemented by SNOMED CT (clinical vocabulary), LOINC (laboratory), ICD-11 (disease classification in force since 2022), DICOM (imaging), ATC/DDD and INN (WHO pharmacological classification). Compliance with ISO 27799:2025 (health information), ISO/IEC 27001 (security management), IHE Profiles (cross-sectional interoperability), WHO Global Strategy on Digital Health 2020-2027 (extended by WHA78(22) May 2025).

On the technical detail of implementation

Institutional note on the balance of technical transparency: the conceptual architecture articulated above (the seven functional layers, the interoperability standards, the consensus model, the cryptographic identity principles) constitutes the public demonstration of technical rigor of the system. The specific implementation detail — complete data schemas, communication protocols between components, specific algorithms, deployment sequences — is documented in the technical repository under control of the Foundation of the Standard (see §10) and available for audit by qualified independent technical teams under technical confidentiality agreement.

Institutional rationale for this balance: the institutional transparency of the system (governance, constitutional framework, verifiable benefits, public success metrics, annual external audit) is maximum. The technical transparency of implementation is mediated by the Foundation of the Standard — accessible for qualified technical verification, not exposed as open source at this stage. The reason is structural: to prevent an actor with resources and artificial intelligence from reimplementing a clone of the system with hidden capabilities or operational opacity, and selling it to the State or to private actors as a substitute for the official standard. The defense against an unauditable competing platform requires that the technical detail remain under control of the Foundation of the Standard that assumes public responsibility for the standard.

This decision is explicitly articulated to fulfill a dual function: (1) maximum public institutional audit over the proposal and its implementation; (2) protection of the technical integrity of the standard against appropriation with backdoors.

§4. Pharmacovigilance platform (ADR) — the artery that detects obstructions

Additional critical functional layer. ARTERIA operates active surveillance of adverse drug events (ADR — Adverse Drug Reactions) with multi-source automatic correlation.

4.1. How the surveillance operates

When a patient reports an adverse event from their native client, the system automatically correlates six integrated sources: the product in the national registry (interactions + known ADRs + National Pharmacotherapeutic Formulary), the prescription that originated the use, the prescriber and their accreditation, the distribution channel and the dispensed batch, the manufacturer of the batch, and the active stock of the affected batch nationwide.

The correlation triggers automatic decision: systemic pattern detected → INVIMA alert + batch withdrawal + registry update + notification to all dispensers with stock; isolated case → statistical record for ongoing pharmacological surveillance.

4.2. Why it matters

Current reactive pharmacovigilance detects systemic patterns years after the first cases, when accumulated damage is already significant. ARTERIA detects correlations in hours or days: the correlation algorithm operates over the event graph in real time. The difference between two hepatotoxicity cases of a specific batch and "we already withdrew that medication" ceases to be measured in years and is measured in days.

ARTERIA: health that flows, life that arrives. When the artery detects local obstruction, it irrigates collateral before the tissue dies.

§5. UPC to UPE transition — the how, when, and why

5.1. Why the transition is structurally necessary

As articulated in §1.2, the per-affiliate capitation model (UPC) economically incentivizes non-care. The EPS earns monthly for each enrolled affiliate regardless of whether it attends them. This is an inverted property of the model, not a correctable operational failure.

The per-event-attended capitation model (UPE — per-event payment unit) inverts the incentive: the IPS earns when it effectively attends, validated by the signature of the patient + the professional + the provider + the BFT consensus. Without attended and confirmed event, there is no release of UPE to the provider.

5.2. How the transition operates

ARTERIA proposes progressive operational transition, not big-bang:

Phase A — Coexistence with verification (months 12-18): the UPC continues flowing to the EPS under the current model, but conditioned on mandatory transfer to IPS upon event confirmed in ARTERIA. Each UPC retained without a corresponding event is publicly recorded. The EPS can no longer capture the flow silently; each retained peso is auditable.

Phase B — Flow inversion (months 18-24): the UPC is assigned to the patient directly under the custody of the regulated custodian bank. Upon each event confirmed in ARTERIA, a smart contract releases the patient's UPC fraction to the IPS that attended. The EPS ceases to be the primary recipient of the flow. It retains the role of subordinate logistical operator (administrative management, provider network, patient support) under contract with verifiable added value.

Phase C — Full UPE in force (month 30 onwards): the UPE completely replaces the UPC in its current form. EPS that retained the role of logistical operators continue operating under contract paid by verifiable service. Those that did not find a real operational function cease operations due to economic unviability.

5.3. Continuity guarantees during the transition

• Zero coverage disruption for the patient: throughout the transition, the patient continues accessing services without additional procedure
• Flow guarantee to IPS: the custodian bank guarantees payments to IPS on confirmed events within the time established by the smart contract (≤ 30 days)
• Subsidized technological adaptation: rural and small IPS receive technical enablement kit + free training during the first 18 months
• Legal compatibility period: during months 0-12, ARTERIA operates in parallel with the current model. IPS can report simultaneously in both systems while the integrity of the migration is validated

5.4. Why this model gains legitimacy quickly

The patient perceives the change within the first weeks of Phase A: they will stop receiving administrative denials, authorization delays, and arbitrary network reductions. The professional perceives the change in the same window: they will stop operating under the pressure of intermediate authorizations and start receiving payments for their effective work. The small IPS, the rural one, the popular neighborhood IPS perceives the change: it will stop depending on the opaque negotiation with the EPS to survive financially.

The actors who lose are the intermediaries who extract value without adding it. That is the design.

§6. Repeal of legacy normative framework and replacement

The transition of ARTERIA requires specific repeal or modification of several norms in force designed for the insurer-centric model. It is not cosmetic adjustment over existing norms — it is structural replacement of the regulatory scaffolding.

6.1. List of norms to repeal, modify, or invoke

The repeal is NOT total or indiscriminate — it is surgical, directed at the articles that sustain fragmentation, opacity, and capture. The constitutional framework of the right to health + universal coverage + financial co-responsibility remains intact and is strengthened under the frame of Statutory Law 1751 of 2015.

Important note on previous paradigms of digital modernization: the architectures of integration bus type X-Road (Estonia) and corporate Enterprise Service Bus (ESB) have been a reference in regional digital government discussions. The Colombian X-Road project of the National Digital Agency + MinTIC (announced 2021, in implementation during 2024–2025) is directed at general government interoperability, with scope limited to the health sector at the close of the period. The relevant structural distinction: integration buses are messaging between preexisting legacy systems, which presupposes that those systems are coherent and complete in themselves. When the legacy systems themselves are fragmented, their data models are incompatible, and their operational owners compete for flow capture (situation documented in Comptroller General reports on health information system fragmentation — PISIS, SISPRO, BDUA, MIPRES, UEHR with low partial implementation per Law 2015/2020 + Res. 866/2021), no integration bus solves the problem — it only encapsulates it in an additional layer. ARTERIA is not an integration bus. It is a single platform with national cryptographic identity, immutable registry, BFT consensus, and smart contracts from the ground up. Compatibility with legacy systems is operational during transition (coverage Appendix #07); the final architecture is structurally distinct from any integration bus.

The repeal is NOT total or indiscriminate — it is surgical, directed at the articles that sustain fragmentation, opacity, and capture. The constitutional framework of the right to health + universal coverage + financial co-responsibility remains intact and is strengthened.

6.2. Resolution 3100 — why it must be repealed first

Resolution 3100 of 2019 (with its subsequent updates) defines the accreditation of health providers under the model of integration into the network contracted by EPS. Accreditation is tied to:

1. Periodic documentary accreditation of physical, technical, and administrative criteria (with high costs that exclude small IPS)
2. Membership in the network contracted by at least one EPS (without a network, the IPS cannot bill)
3. Reactive verification by periodic visit from Supersalud (no continuous technical verification)

Under the ARTERIA UPE model, this structure is structurally incompatible:

• The IPS contracts directly with the patient (not with the EPS) — the contracted network ceases to be a variable
• Verification of criteria is technical, continuous, automatic (the platform validates compliance at each event; no periodic visits required)
• Accreditation moves from entity-centric model (is this company an IPS?) to function-centric model (does it have accredited technical capacity for this specific act?)

6.3. What replaces Resolution 3100

New resolution, decreed at month 6 of ARTERIA operation. Proposed structure:

Operational effect: independent professionals who today cannot practice for lack of an EPS network, rural IPS that cannot maintain 3100 accreditation due to cost, specialists in rare pathologies who today have no contract — all can practice under verified functional accreditation. Effective system coverage expands structurally.

6.4. Normative framework of the transition

The repeal + replacement is executed in four sequential instruments:

§6.5. Quality-differential payment — the continuous improvement mechanism

Structural component of the UPE model. Payment to the provider, to the professional, to the dispensing service is not a single value — it is a range with an objective scale based on verifiable quality metrics.

The operational principle

Each system component (physician, nurse, technician, hospital bed, room, medical device, dispensed medication, diagnostic service) has a verifiable multidimensional quality profile. The effective payment on confirmed event is adjusted according to that profile.

Precise operational analogy: in urban mobility applications, the driver charges differently according to the vehicle, according to their accumulated passenger rating, according to response time. The user pays what they choose. The system economically rewards real measured quality, not declared on paper.

ARTERIA applies the same principle to the health system, with professionally appropriate metrics.

Quality metrics by category

Formal mapping with the seven primary care quality attributes (Resolution 2696 of 2024)

The above metrics materialize the seven quality attributes declared by Resolution 2696 of 2024 of the Ministry of Health:

The seven attributes are operationalized as a factor of differential payment, not as an aspirational declaration. What Resolution 2696/2024 defines as a quality criterion becomes a parameter that adjusts the effective payment on each attended event.

Construction and publication of metrics

• No self-reporting. Metrics are constructed automatically over events signed in the system. There is no manual declaration of quality.
• Multi-source. Patient rating (automatic post-consultation), professional peer review, verifiable clinical outcomes, objective evidence (not falsifiable by interests).
• Public. Each provider, professional, IPS has a public profile with their historical metrics. The patient can consult before accepting assignment.
• Audited. National technical council continuously audits the construction of metrics to avoid biases or gaming of the system.

Why it matters structurally

• Rewards real quality, not the quantity of services provided. Today the system pays by volume — the incentive is to see more patients in less time, which degrades care. ARTERIA pays for delivered value.
• Makes quality transparent as public information. The patient can see. The physician knows how they are evaluated. The IPS knows where it is losing competitiveness.
• Structural continuous improvement. Actors that do not improve receive fewer assigned events (via the dynamic assignment mechanism) and lower remuneration when they do receive events. They have real economic incentive to improve or cease operations.
• Upward technical mobility. A young professional with good performance scales remuneration quickly without having to wait decades. A small IPS with excellent service competes with mediocre large hospitals.
• Not destructive competition. The metrics reward collaboration (nurse/patient ratio, timely referral), not extractive individualism.

Ethical guarantees

• Prohibited differential payment based on patient characteristics (age, preexisting condition, income, geographic location). The patient pays the same regardless of their profile.
• Universal coverage preserved. The patient receives guaranteed minimum technical quality care throughout the system — the differential rewards superior quality, does not allow inferior quality below the minimum standard.
• Continuous audit to prevent hidden discrimination via metrics.

Institutional note: the specific algorithm for calculating differential payment (exact mathematical formula, weighting factors by category, metric-to-payment-factor mapping function) is documented in the technical repository of the Foundation of the Standard under the same institutional balance articulated in §3 — auditable by qualified technical teams, not exposed as open source at this stage to preserve the integrity of the standard against reimplementation with hidden biases.

§7. Operational timeline 0-30 months

7.1. Milestones by quarter

7.2. Verifiable metrics by quarter

Each milestone has a publicly verifiable quantifiable metric. Verification does not depend on the Ministry — any independent auditor can consult the citizen dashboard and validate progress.

Examples of metrics:

• Average appointment scheduling time (month 6: international standard; measurable in hours)
• Percentage of pharmaceutical registry published (month 15: 100%)
• Percentage of UPC flowing in the new model (month 18: ≥ 50%; month 24: 100%)
• ADR events automatically correlated vs. manual reports (month 21: ratio ≥ 5:1)
• IPS operating under new accreditation (month 30: 100%)
• Projected financial recovery of 43% lost (cumulative year over year)

7.3. Contingencies and foreseen fracture points

Month 12 — political fracture point: the start of Phase A is the moment when actors who lose structural function will articulate active political opposition. The response strategy:

• Sustained public communication with verifiable data of progress
• Multiple technical spokespersons (scientific societies, university deans, patient associations)
• Constitutional framework + international treaties (International Covenant on Economic, Social and Cultural Rights — art. 12 right to health) prepared for legal defense

Month 24 — legal fracture point: the repeal of Resolution 3100 will generate constitutional lawsuits by affected sectors. The strategy:

• Constitutionality of the reform sustained on technical evidence (the new regulation expands access to health, does not restrict it)
• International treaties as backing
• Comparative jurisprudence (similar systems operating in OECD countries)

§8. Resources, costs, savings

8.1. Required investment

8.2. Projected financial recovery

ARTERIA structurally closes the system's loss vectors documented by national authorities:

Modernization is self-financing with a fraction of the projected recovery of the first full year. The rest of the flow is redirected toward better citizen care, better remuneration of health human talent, and structural sustainability of the system.

§9. Structural anti-corruption by architecture

The elimination of corruption is not a political promise of discretionary application. It is architectural property of the system:

9.1. Auto-initiation of sanctioning proceedings before Supersalud

The system detects and automatically triggers disciplinary proceedings before Supersalud when it registers verifiable non-compliance. Supersalud operates under the same national technical standard (ARTERIA), so the integration is native, not by additional interface.

How it operates:

1. Each system actor (patient, professional, IPS, EPS, dispenser, manufacturer, regulator) has operational obligations coded in smart contracts (response deadlines, minimum quality, mandatory transparency, mandatory reporting).
2. The smart contract detects when an obligation is breached (example: EPS does not nominate a provider 30 days after the attended event; or IPS does not deliver a diagnostic test 72 hours after taken; or manufacturer does not respond to an ADR alert within 48 hours).
3. The smart contract automatically opens a disciplinary process before Supersalud, with the evidence already consolidated and cryptographically signed. Supersalud does not investigate from scratch — it receives the documented case.
4. Supersalud verifies the case under its regular legal procedure (with due process guarantees for the respondent), applies sanction if appropriate, and the sanction is executed via smart contract.
5. Every sanctioning decision is public, signed, auditable. There is no silent or archived decision.

Why it matters:

• The current Supersalud investigates less than 5% of verifiable non-compliances, because it depends on manual complaints and its limited inspection capacity. ARTERIA inverts the equation: 100% of verifiable non-compliances trigger an automatic process.
• The power asymmetry between patient (complainant) and EPS (respondent) disappears: the system reports to the system.
• The discretion to archive cases due to political or economic pressure is reduced — the disciplinary process is initiated and registered before it reaches the official's desk.
• Sanctions are proportional to the non-compliance (automatic scale) and cumulative (an actor with a history of non-compliance faces greater sanctions).
• Supersalud moves from being an overwhelmed reactive investigator to a technical arbiter over consolidated evidence.

§10. Proposed institutional framework

10.1. Who operates the standard

ARTERIA is operationally sustained by a Foundation of the Standard, with a mixed technical council:

Qualified majority of 2/3 for strategic decisions. Mandatory transparency of minutes.

10.2. The Ministry of Health under ARTERIA

The Ministry retains its role as regulatory and rectoral authority. It does not operate the platform. This is key:

• Governmental continuity: change of government does not produce operational reset
• Reduced political capture: impossible to capture the operator via executive appointment
• Technical efficiency: the Foundation operates with technical criteria, not electoral ones
• Financial sustainability: transaction fees + academic resources, not exclusive dependence on the National Budget

10.3. INVIMA, Supersalud, CNPM under ARTERIA

These authorities maintain their full regulatory mandate. What changes is their mode of operation: they move from maintaining isolated databases to operating over the unified registry with public transparency. Their decisions are executed as auditable smart contracts; their minutes are immutable; their sanctions are automatically applied over verified events.

The regulatory power of the State is amplified, not reduced. What is reduced is the capture of regulatory power by private interests that operate in opacity.

10.4. System regime — mandatory, free, financed by the Ministry

ARTERIA is a single mandatory national standard for every operational interaction of the Colombian health system. This means:

Why it is structural that it be mandatory:

A national technical health system that operates as a voluntary option parallel to a captured legacy system remains a minority technology. EPS that benefit from the captured model do not migrate voluntarily; captured actors do not allow transparency voluntarily. Mandatoriness is the condition for universal transparency.

Why it is structural that it be free:

Any per-transaction fee model creates regressive friction: rural IPS, independent professionals, lower-income patients would pay proportionally more for using the system. Universal gratuity is a condition for real universal coverage.

Why it is structural that the Ministry finances it:

If the system is financed by selling services to private actors, the system's bias toward those actors is incentivized. If the public budget finances it, the system is accountable to the citizen via the State, not to a commercial client. The Foundation accounts to the citizen through the Ministry + annual external audit + public dashboards.

§11. Operational compatibility with current framework during transition

Critical question for every actor in the current system: "what happens with what operates today while this is being implemented?"

Operational answer:

• Months 0-12: ARTERIA operates in parallel with the current system. IPS can report simultaneously in both systems. EPS continue operating under the current UPC model. People continue receiving care as today. The change is opt-in for voluntary pioneers.

• Months 12-24: ARTERIA is operationally the official system; the legacy system enters read-only mode for historical audit. EPS that have opted to transform into subordinate logistical operators continue operating under contract. Those that do not gradually find economic unviability and cease operations by market.

• Months 24-30: ARTERIA is the single system. All actors operate under the new framework.

At no point does the patient lose coverage due to the transition. The operational commitment is explicit: no Colombian is left without access to their care during the change.

§12. Public success metrics

ARTERIA will be quantitatively evaluable from day 1 on verifiable metrics:

All these metrics are published on citizen dashboards updated in real time. Accountability does not require an investigative commission — it is done by default, all the time.

§13. Alignment with the current national normative framework

ARTERIA does NOT contradict the national health policy declared by the Ministry of Health and Social Protection in its current norms 2024-2026. It materializes them operationally — and materializes them better than the administrative apparatus that has produced them without operationalizing them. Where it diverges is in specific mechanisms of the insurance model that require structural reform (UPC → UPE transition + direct ADRES → IPS payment), articulated via a specific Bill of Law with constitutional basis in Statutory Law 1751 of 2015.

13.1. Formal mapping with the National Health Quality Policy 2026-2035 (Res. 1058 of 2026)

13.2. Formal mapping with the Preventive Predictive and Resolutive Model (Decree 858 of 2025)

13.3. Formal mapping with the Public Policy on Health Human Talent 2025-2035 (Res. 1444 of 2025)

13.4. Formal mapping with the seven primary care quality attributes (Res. 2696 of 2024)

See §6.5 — the seven attributes are operationalized as a factor of the quality-differential payment, with specific multidimensional metrics by provider category.

13.5. Formal mapping with the National Rural Health Plan (Decree 351 of 2025)

13.6. Formal mapping with Integral Territorial Management (Res. 1597 of 2025)

13.7. Formal mapping with territorialization in 10 regions and 119 subregions (Res. 1789 of 2025)

The federation of ARTERIA infrastructure nodes operates coherently with the 10 regions and 119 subregions defined by Resolution 1789 of 2025. Each region/subregion maintains:

• Operational territorial coordinator within the framework of the national standard
• Infrastructure nodes with national backup (federation)
• RIITS specific to local geography and population
• Compliance with the territorial Public Health Plan integrated into the national registry

13.8. Strategic positioning: ARTERIA as accelerator, not substitute

ARTERIA DOES NOT postpone or annul the 2031, 2033, 2035 horizons declared by current public policy. It brings them forward operationally. What the policy declares as a medium-term aspiration, ARTERIA delivers as executable short-term architecture, maintaining full coherence with the declared principles, axes, pillars, lines, and attributes.

13.9. What does require structural reform sustained by a Bill of Law

These are the explicit structural discrepancies with the current framework that ARTERIA proposes, not as compliance but as reform:

These discrepancies are sustained by:

• Constitutional basis: Statutory Law 1751/2015 (fundamental right to health) + Constitution arts. 48, 49
• Legislative vehicle: Specific Bill of Law for surgical modification of Law 100, Decree 4747, Resolution 3100, and related norms
• Universal coverage preserved: the UPC → UPE transition does NOT dismantle coverage or introduce economic barriers to the patient — it inverts the intermediary insurer's incentive

§14. Conclusion and call

The Colombian health system is obstructed. The obstruction is not accidental, not transitory, not correctable by more administrative reform over the current model. It is a structural property of the design built during three decades of intermediation structurally incentivized not to attend.

ARTERIA closes the obstruction by architecture. It does not reform the system within its captured logic — it replaces the logic. The flow of the health peso goes to the attended event, not to the intermediary; the flow of information goes to the patient and the professional, not to the bureaucratic layers that block it; the flow of regulation is public and verifiable, not opaque and subject to capture.

The technology exists. The architecture is articulated. The components are operationally proven at the scale required. The resources are there — the 30 to 40 trillion lost annually are the financing of modernization. The human talent is there — Colombian health sector professionals have sustained the system under impossible pressure and are the first to gain from the transformation. Political will can materialize: the choice between continuity of the captured model or structural modernization is a government decision executed by the signature of a regulatory decree and the filing of a bill of law.

The cost of inaction is measurable. The system's structural deficit grows — AFIDRO projects $37 trillion accumulated for 2026, on a starting point of $30 trillion as of Dec-2025. Receivables more than 90 days past due remain at 58% of debt to IPS (ACHC). Each month the system remains as it is, the deficit deepens, fiscal liability proceedings accumulate at the Comptroller General, thousands of appointments are not scheduled in time, adverse drug events are not detected in time, and a significant number of Colombians die distal to arterial obstructions that were preventable.

ARTERIA: life arrives.

Health that flows, life that arrives — to the patient, without obstructions, without delays, without losses along the way.
