A 24-year-old woman presents to the emergency department 18 hours after alleged sexual assault. She is conscious, cooperative, and has no acute injuries. On examination, there is no visible genital trauma. She reports vaginal pain and mild bleeding. What is the most appropriate immediate next step in management?

Explanation

## Immediate Management of Rape Survivor — Forensic Priority **Key Point:** The first and most critical step after ensuring medical stability is to perform a comprehensive forensic medical examination with proper chain-of-custody documentation. This window is time-sensitive and must not be delayed. ### Timing and Rationale **High-Yield:** Forensic evidence is most reliable within 72 hours of the alleged assault, with biological evidence (semen, saliva, blood) being recoverable even up to 48–72 hours post-assault. At 18 hours, the patient is still within the optimal window for evidence collection. ### Components of Forensic Examination | Element | Purpose | Timing | |---------|---------|--------| | Genital swabs (high/low vaginal, cervical, anal) | DNA evidence from perpetrator | Within 72 hours | | Oral swabs | Saliva, semen evidence | Within 72 hours | | Hair combing and collection | Fibre and hair evidence | Within 72 hours | | Clothing and debris | Trace evidence | Immediate | | Photographic documentation | Visual record of injuries | Before treatment | | Detailed history and examination findings | Medico-legal record | Contemporaneous | **Clinical Pearl:** Absence of visible genital trauma does NOT exclude sexual assault. Many rape survivors have no physical injuries, especially if the assault involved non-penetrative acts or if the perpetrator used minimal force. Forensic evidence collection is independent of injury severity. ### Chain of Custody **Key Point:** Every sample must be labelled, sealed, and documented with: - Patient identification - Date, time, and collector's name - Witness signature (if available) - Unbroken documentation until handover to police/laboratory Failure to maintain chain of custody renders evidence inadmissible in court. ### IPC Relevance Under **IPC Section 375** (rape) and **Section 376** (punishment for rape), the medical examination report is crucial evidence. The examination must be conducted by a female doctor (or female health worker if doctor unavailable) with the woman's informed consent, as per **POCSO Act, 2012** and **Criminal Law Amendment Act, 2013**. **Mnemonic: SAFE Protocol** — **S**exual history, **A**ssault history, **F**orensic examination, **E**vidence collection and emotional support.
