Rebooting Care Coordination for AI

An architecture document for what care coordination could look like if we started from AI as a precondition, not a feature bolted onto existing workflows.

Most AI in healthcare today gets bolted onto existing products. The result is faster versions of the same workflow, with the same structural assumptions about who does what and when. This document asks a different question: if AI were the foundation, not the addition, what would the product become? It is the architecture behind a working prototype, written before the build.

The problem with the current state

Care managers manually track 150+ members and decide who to reach out to, in what order, for what reason. The work is structured the same way it was a decade ago: lists, tasks, queues. The volume has grown. The structure has not.

This doesn't scale, and it burns out the people doing the work. More importantly, it forces a zero-sum trade-off between three things every modern care platform claims to want: collaborative operations for high-touch cases, coherent clinical and social data, and holistic product design that brings it all together. When organizational capacity is finite, these three goals compete with each other. Whichever loses, the system fragments.

The vision

An AI-first care platform, while preserving high-touch capacity for complex, high-need populations.

The model is closer to AI-powered air traffic control than self-service kiosks:

The product becomes the intelligence layer that says: "These twelve members need your attention today. Here's why. Here's what to say. Here are the updated care plans ready for you to review."

AI's value isn't in making the old workflow faster. It's in clearing the structural problems that quietly block everything, so design, technology, and the human work of care can finally move.

The framework: a three-tier work architecture

The principle: default to lightweight, escalate to structured only when needed. Most care coordination work doesn't need a project plan. Some of it does. The product should match the structure to the work, not the other way around.

Tier 1≈ 80% of work volume
Action Feed
Trigger

AI detects a single, clear action for one person.

Characteristics
  • No dependencies
  • One owner
  • Can be completed in a single interaction
  • Disposable. Once done, it's gone.
Examples
  • "Call Maria about missed diabetes appointment"
  • "Review John's recent ER visit notes"
  • "Send medication refill reminder to 5 members"
Interface

Swipeable cards, quick actions, mark complete. AI reasoning visible but not overwhelming. Human override always available.

Tier 2≈ 15% of work volume
Care Episodes
Trigger

An Action Feed item reveals complexity, or a human initiates one.

Characteristics
  • Multiple steps over time
  • Still primarily one owner
  • Sequential, not parallel dependencies
  • Time-bound
Examples
  • "Get Sarah enrolled in diabetes management program" — requires education call, consent form, schedule first visit, confirm attendance.
Interface

Expandable checklist within the member profile. Tracks progress. One-click promotion to Tier 3 when needed.

Tier 3≈ 5% of work volume
Care Coordination Projects
Trigger

An explicit human decision that multiple people need visibility and coordination.

Characteristics
  • Multiple owners with parallel work
  • Dependencies between team members
  • Unclear timeline or high complexity
  • Needs shared context and documentation
Examples
  • Housing placement for an unstable member
  • Post-hospitalization transition coordination
  • Complex behavioral health and medical co-management
Interface

Full task board with assignments, status, notes, and explicit handoffs.

The user experience:

Key rule: you can escalate up, but you can't demote down. Once something becomes a Project, it stays that way until complete. This preserves context and history, and prevents work from being silently downgraded out of sight.

Design principles

Low friction for high-volume work

Most actions should be one to two clicks. Default to simple views. Progressive disclosure of complexity only when the situation demands it.

Clear mental model

Care managers should immediately understand "what type of work is this?" Visual distinction between tiers. Obvious escalation paths.

Preserve context

All work tied to the member profile. History visible across tiers. Handoffs between team members are explicit, not implicit.

AI transparency

Show why AI flagged something. Allow human override. Make AI reasoning visible, but not overwhelming. The goal is calibrated trust, not blind trust.

Open questions worth investigating

This architecture is field-thinking, not field-tested. A few questions remain open:

Why publish this

This document was the architecture behind a working prototype I built to test the approach. The prototype is not yet public. The thinking is.

I'm publishing it because the strongest evidence of an AI-forward designer is not the polished case study. It's the working document that shows how the problem was framed before any tool was reached for. Most "AI design" content focuses on the tools. The harder, less-discussed part is the architecture.

If you're working on something similar, or you think this is wrong somewhere, I'd genuinely like to hear it.
