Older Adult Discharged After Delirium Without Demonstrable Reassessment of Capacity, Medication Plan, Functional Readiness, Caregiver Acceptance, and Transfer of Responsibility
Constitutional first cause
The Engine begins when:
An older adult who experienced delirium is being considered for discharge or transfer while cognitive, functional, medication, and support conditions may differ from the pre-hospital baseline.
The first cause is not a later readmission or fall.
It is the decision to transfer execution obligations out of the hospital.
Obligation architecture
1Event observed — Discharge or transfer is proposed following an episode of delirium.
2Obligation 1 — Delirium-status reassessment — The patient’s current attention, cognition, and trajectory must be reassessed. — Evidence: delirium screening, cognitive examination, comparison with prior baseline, clinical note.
3Obligation 2 — Decision-making capacity assessment — Capacity must be assessed for the specific decisions the patient is expected to make when there is reason for concern. — Evidence: decision-specific assessment, documentation of understanding, appreciation, reasoning, and expression of choice.
4Obligation 3 — Surrogate or caregiver identification — Where the patient cannot independently execute the plan, the appropriate surrogate, caregiver, or receiving organization must be identified. — Evidence: authorized representative, caregiver record, receiving-facility contact.
5Obligation 4 — Medication reconciliation — Pre-admission medications, inpatient changes, discontinued medications, and the discharge regimen must be reconciled into one executable plan. — Evidence: reconciled medication list, rationale for changes, pharmacy communication.
6Obligation 5 — Functional readiness assessment — Mobility, transfers, feeding, toileting, cognition, and other necessary activities must be evaluated against the proposed destination. — Evidence: nursing, physical therapy, occupational therapy, speech or swallowing assessments.
7Obligation 6 — Environmental and support requirements — Required supervision, equipment, home health, rehabilitation, transportation, nutrition, and follow-up support must be established. — Evidence: orders, delivery confirmation, service acceptance, placement record.
8Obligation 7 — Caregiver or receiving-party acceptance — The person or organization inheriting daily execution obligations must explicitly accept them and demonstrate an ability to perform them. — Evidence: caregiver teaching record, acceptance, facility admission, documented refusal or limitation.
9Obligation 8 — Comprehension verification — Instructions must be understood by the actual person expected to execute them. — Evidence: teach-back, medication demonstration, written and verbal instructions, proxy acknowledgement.
10Obligation 9 — Transfer of custody — Clinical responsibility must be demonstrably transferred, with an identified owner for unresolved issues. — Evidence: handoff, discharge summary receipt, named follow-up owner, transfer timestamp.
11Obligation 10 — Early post-discharge verification — The system must verify that medications, services, appointments, supervision, and the destination plan became real. — Evidence: follow-up call, home-health visit, primary-care review, pharmacy fill, facility medication administration record.
Constitutional observations
What The Engine makes visible
A conventional record can show:
the delirium was documented;
the discharge summary was signed;
medication instructions were printed;
therapy assessed the patient;
family was “informed”;
home health was ordered;
and a follow-up appointment was entered.
The Engine asks a harder question:
Who actually accepted the obligations required to keep this patient safe after the hospital stopped performing them?
That is the accountability center of the case.
Constitutional-property mapping
This case exercises:
CP-001 — Referral Continuity
CP-003 — Dynamic Obligation Creation
CP-005 — Evidence-Dependent Obligation Gating
CP-006 — Accountable Choice
CP-007 — Distributed Obligation Convergence
It also independently tests three provisional principles.
Dynamic Decision-Making Capacity — second observation
First observed in Psychiatry.
In geriatrics, delirium makes the issue more explicit because capacity can change over hours or days. A decision documented at one moment cannot automatically be assumed valid for every later decision or execution obligation.
Status: Second independent observation; still not approved.
Obligation Reconciliation — second observation
First observed in Primary Care.
Here the medication, functional, safety, caregiver, and follow-up plans must be reconciled into one discharge plan that can actually be executed.
Status: Second independent observation; still not approved.
Dynamic Custody Transfer — second observation
First observed in Critical Care.
Here custody transfers from a staffed clinical environment to a patient, caregiver, facility, or home-care network. The receiving party’s acceptance and capability matter as much as the discharge order.
Status: Second independent observation; still not approved.
Why no promotion yet
This is strong recurrence, but each candidate still needs sharper boundaries:
Dynamic capacity must be distinguished from ordinary accountable choice.
Obligation reconciliation must be distinguished from convergence and dependency gating.
Dynamic custody transfer must be distinguished from referral continuity and ordinary handoff.
Geriatrics gives us independent confirmation. It does not yet settle those distinctions.
No worked demonstration is provisioned for this specialty in this build. Occupational Medicine (Specialty 25) is the first domain and carries the worked demonstration; the constitutional architecture above is shared across specialties.
