Overview

1. CL-08 (Clinical Decision Support) — re-evaluates rules (drug-disease interactions, monitoring, quality-measure gaps) when active problems change.
2. PM-07 (Encounter Diagnosis Capture / Charge Entry) — pre-populates encounter diagnoses from the patient’s active problem list at encounter creation/check-in, so coders/clinicians do not re-enter chronic conditions.

Cross-Core Read API

// src/platform/clinical/index.ts (re-export)
export { usePatientActiveProblems } from '@/platform/clinical/hooks/usePatientActiveProblems';

// Consumer (PM-07 charge capture)
import { usePatientActiveProblems } from '@/platform/clinical';

const { data: problems, isLoading } = usePatientActiveProblems(patientId);
// problems: Array<{ problem_id, icd10_code, icd10_display, onset_date, priority }>

SELECT * FROM cl_get_patient_active_problems(p_organization_id := $1, p_patient_id := $2);

​

Security and RLS

• cl_problems has RLS enabled with FORCE ROW LEVEL SECURITY; all CRUD policies scope by organization_id via cl_user_has_problem_permission(action).
• Cross-core reads from PM-07 execute under the calling user’s auth context — RLS still applies. The SECURITY DEFINER helper does not bypass tenant scoping; it only avoids the need for PM code to know CL table internals.
• Event payload contains no PHI; consumers MUST re-fetch via the read API to obtain ICD-10 display text or clinician description.
• Status state-machine enforcement (e.g., entered_in_error is terminal) is implemented in a BEFORE UPDATE trigger on cl_problems, not in the RLS WITH CHECK clause (which has no access to OLD).

​

Idempotency, Retry, and Ordering

• Idempotency key: problem_id || ':' || action || ':' || changed_at (ISO-8601, millisecond precision). Subscribers MUST de-duplicate using this key for at least 24 h.
• Ordering: Not strictly guaranteed across the domain_events channel. Subscribers MUST treat events as state notifications (re-fetch on receipt) rather than authoritative deltas.
• Retry: PF event dispatcher retries with exponential backoff (per PF-70 event publishing standards). Failed deliveries land in the dead-letter queue after 5 attempts.
• Backfill: On subscriber outage recovery, consumers may call the read API to reconcile state; no replay of historical events is provided.
