SAFETY-CRITICAL — Joint Commission NPSG.15.01.01 compliance dossier. New dossier authored 2026-05-13 in B.8 re-dispatch. Owns ED-setting acute suicidality assessment, containment, safety planning, admission disposition, AND post-discharge outpatient bridge (Zero Suicide / Caring Contacts cascade) after the 2026-05-14 depth-pass-1. Cross-references psych.depression.core.v1 for longitudinal MDD pharmacotherapy (no overlap; composes via sibling_differentiation and action_plan handoff). CRITICAL anti-pattern warnings baked in: do NOT discharge active SI with plan + means + refusal; do NOT use no-suicide contracts as sole intervention (APA 2016 explicit); do NOT initiate SSRI in ED for known/suspected bipolar; do NOT initiate benzodiazepine acutely in suicidal patient (disinhibition risk). Stanley-Brown Safety Planning Intervention 6 steps encoded in action_plan; printable patient handout template referenced (psych-safety-plan.template.ts) but generator integration pending. Lethal means restriction is the single highest-impact intervention (UK paracetamol pack-size — Hawton BMJ 2013 PMID 23386268; firearm 3–5× US household-suicide risk — Anglemyer Ann Intern Med 2014 PMID 24492417; Yip Lancet 2012 PMID 22726520 systematic review). Caring Contacts 24 h / 72 h / 1 week call cascade post-discharge is evidence-based for completed-suicide reduction (Motto Psychiatr Serv 2001 PMID 11433109 — 2-yr suicide death halved; Stanley/Brown JAMA Psychiatry 2018 PMID 30209345 — SPI + 2-call follow-up cuts 6-mo suicidal behavior 45%). PRODUCTION blockers: (1) calc.cssrs not in calc-registry, (2) RxCUIs need RxNav validation, (3) targeted test file pending, (4) several bridge atoms (1:1, ligature-safe, stanley_brown_safety_plan, means_restriction_counseling, involuntary_hold_evaluation) referenced as inline non_drug actions rather than registered workups — promote when registry adds these atoms. HUMAN REVIEW: thresholds and anti-pattern warnings reviewed against APA 2003 + 2016 + APA 2025 + Joint Commission NPSG.15.01.01 + ED-SAFE + Zero Suicide; no clinical threshold lowered vs prior content in psych.depression.core.v1; no outpatient management of high-risk SI introduced — outpatient playbook is bridge-only (Zero Suicide framework), with explicit escalation triggers back to ED. Deepened 2026-05-14 (shard-5-obped-id depth-pass-1): added co-located _briefs/psych.suicidality.ed.core.v1.depth.md companion brief (complement, did not overwrite the 2026-05-13 original brief) + co-located _research-bundles/psych.suicidality.ed.core.v1.md. Promoted ED-SAFE (PMID 28245301) and Stanley/Brown 2018 JAMA Psychiatry RCT (PMID 30209345) into evidence.pmids (7 → 9 PMIDs). Bumped last_reconciled 2026-05-13 → 2026-05-14. Deepened 2026-05-14: added outpatient setting playbook (Zero Suicide bridge appointment ≤ 1 wk + Stanley-Brown SPI reinforcement + lethal-means restriction confirmation + Caring Contacts 24 h / 72 h / 1 wk cascade + ASIST / CALM referral + family/support engagement). settings: array expanded acute|transition → acute|transition|outpatient. Deepened 2026-05-14: added severity_triggers (3 new of 9 total): recent_attempt_within_72h (severe — past-72h-attempt LR+ ≈ 8 for 30-day repeat; admission default unless attending attestation + bridge ≤ 1 wk); elopement_risk (severe — flight risk → 1:1 + locked psych ED + voluntary→involuntary escalation); failed_outpatient_safety_planning (severe — patient declines safety plan / means restriction at bridge → ED same-day, strengthens admission rationale). Phenotype matrix (ideation × method × plan × intent × access-to-means × prior-attempt × precipitating-substance × host × setting) is encoded indirectly via severity_triggers + setting_playbooks + sibling_differentiation. First-class TS field for phenotype matrix is schema-blocked — see docs/framework-audit/shard-5-obped-id-state.md Schema-blocked queue. Bayesian linkage (pre-test 30-day repeat-attempt probability ≈ 8% in ED-screened-positive cohort per Boudreaux 28245301; C-SSRS Ideation 5 + method-access LR+ ≈ 10; past-72-h attempt LR+ ≈ 8; firearm-in-home in active SI LR+ ≈ 4 for completed suicide per Anglemyer 24492417; SPI + 2-call follow-up OR 0.56 over 6 mo per Stanley/Brown 30209345; ED-SAFE bundle RR 0.72 over 12 mo per Boudreaux 28245301; T_admit ~ 30% or hard imminent-risk triggers; T_discharge < 5% with all bridge conditions met) is documented in the co-located _research-bundles/psych.suicidality.ed.core.v1.md. ROS/DDx LR seed data audited by npm run audit:ros-ddx-coverage (cross-cutting; not touched by this shard). Prehospital (EMS) recognition is currently encoded informally via the outpatient → ED transition; a first-class "prehospital" DossierSetting value is schema-blocked.
