A 28-year-old woman with major depressive disorder is evaluated in the emergency department after her partner found her with an empty bottle of her antidepressant (sertraline 100 mg, 30 tablets) and a handwritten note stating "I can't do this anymore. I'm sorry." She reports she took the pills 2 hours ago. Vital signs: BP 110/70, HR 88, RR 16, temperature 37.2°C. She is alert and oriented, tearful, and expresses remorse. She denies ongoing suicidal intent and says "I made a mistake." Her partner reports she has been under stress from job loss and relationship conflict over the past month. She has no prior psychiatric hospitalizations or suicide attempts. What is the most appropriate next step in her management?

Explanation

## Post-Suicide Attempt Risk Assessment & Disposition **Key Point:** A suicide attempt (regardless of lethality or subsequent remorse) is a psychiatric emergency requiring inpatient evaluation and safety monitoring. Remorse and denial of ongoing intent do NOT negate the need for hospitalization after an active attempt. ### Risk Factors in This Case | Factor | Status | Significance | |---|---|---| | **Attempt made** | Yes | Active, intentional self-harm | | **Method** | Overdose (sertraline) | Moderate lethality; SSRI toxicity at high dose | | **Intent clarity** | High | Handwritten note; deliberate action | | **Time since attempt** | 2 hours | Recent; acute medical & psychiatric risk | | **Precipitants** | Job loss, relationship conflict | Acute stressors (modifiable) | | **Prior attempts** | None | Lower static risk, but current attempt = acute crisis | | **Prior hospitalizations** | None | No prior psychiatric treatment engagement | | **Current mental state** | Remorse, denial of intent | **Post-attempt regret is common; does NOT predict safety** | | **Vital signs** | Stable | No acute medical decompensation yet | **High-Yield:** Post-attempt remorse and denial of ongoing intent are **NOT protective factors** and do NOT justify discharge. Many patients who survive attempts express regret; this reflects relief at survival, not resolution of underlying suicidality. **Clinical Pearl:** The **intent-to-die** at the time of attempt is the key variable, not post-hoc regret. This patient wrote a note and took 30 tablets—clear intent. Subsequent remorse does not erase the attempt. ### Why Inpatient Admission Is Mandatory 1. **Active suicide attempt** = acute psychiatric emergency 2. **Overdose toxicity risk** = requires medical monitoring (SIADH, hyponatremia, serotonin syndrome possible with SSRI overdose) 3. **Acute precipitants** (job loss, relationship conflict) = recent stressors not yet resolved 4. **No prior treatment engagement** = patient unfamiliar with psychiatric care; needs intensive stabilization 5. **Safety monitoring** = inpatient setting provides 24/7 observation, medication management, and psychosocial intervention ### Medical Management of SSRI Overdose **Actions:** - Activated charcoal if within 1–2 hours (patient is at 2 hours; consider) - **NO gastric lavage** (low yield, risk of aspiration) - Monitor for serotonin syndrome: agitation, tremor, hyperreflexia, hyperthermia - Check electrolytes (hyponatremia from SIADH possible) - Continuous cardiac monitoring - Admit to medical unit for 24–48 hours observation, then transfer to psychiatry **Mnemonic: SIADH from SSRI** — Sertraline/SSRIs → SIADH → Hyponatremia → Seizures, altered mental status. ### Psychiatric Management - Comprehensive suicide risk reassessment (C-SSRS) - Diagnostic evaluation: rule out bipolar disorder, psychosis, substance use - Medication optimization: current sertraline may be inadequate; consider augmentation or switch - Psychotherapy: CBT, DBT, or interpersonal therapy - Family/partner involvement: psychoeducation, safety planning - Discharge planning: outpatient psychiatry, crisis line, safety contract [cite:American Psychiatric Association Practice Guideline for Suicide Risk Assessment; Toxicology textbook on SSRI overdose management]
