A serious road traffic collision, a safeguarding concern, a hazardous materials exposure, or a complex home environment can all benefit from visual context that is captured at the scene and preserved with the patient record. The challenge is doing that without turning the clinical workflow into an unmanaged media dump or pushing identifiable imagery into the record without safeguards.\n\nThe Scene Evidence Capture module gives crews a controlled way to add photographs, sketches, and other scene artefacts to the encounter while preserving redaction discipline and a clear link back to the original case. It is designed for situations where visual context improves handover, governance review, or later evidence handling, but where the clinical workflow still needs to stay simple in the field.\n\n```mermaid\nflowchart TD\n    A[Active Encounter] --> B[Photo, Sketch, or Scene Artefact]\n    B --> C[Privacy and Redaction Review]\n    C --> D[Direct-to-Storage Upload]\n    D --> E[Encounter-Linked Media Record]\n    E --> F[Clinical Handover and Review]\n    E --> G[Escalation to Formal Evidence Workflow]\n```\n\n**Last Reviewed:** 2026-04-22\n**Last Updated:** 2026-04-22\n\n## Key Features\n\n- **Encounter-Linked Scene Capture**: Attach photos, sketches, and scene artefacts directly to the active encounter so visual context stays with the clinical record.\n\n- **Privacy-Aware Photo Workflow**: Support redaction-aware capture for images that may contain faces, bystanders, or other sensitive information before they become part of the permanent record.\n\n- **Scene Sketching**: Let crews create a quick structured sketch of a room, vehicle position, or incident layout when a simple image does not explain the scene clearly enough.\n\n- **360 and Supporting Artefact Support**: Accommodate richer scene context where a simple single image is insufficient.\n\n- **Direct-to-Storage Upload Pattern**: Keep large media handling out of the frontline user experience so the capture flow remains responsive in the field.\n\n- **Clinical and Evidential Reuse**: Make it possible for the same visual artefacts to support patient handover, internal review, and escalation into wider evidence workflows where required.\n\n## Use Cases\n\n- **Road Traffic Collision Documentation**: A crew captures the patient position, vehicle intrusion, and relevant hazards so the receiving trauma team has clearer scene context.\n\n- **Safeguarding Environment Record**: A clinician records environmental concerns in a home visit where the visual scene materially supports the safeguarding decision.\n\n- **Hazardous Scene Layout**: A quick sketch helps explain access points, contamination zones, or casualty positions for later clinical and operational review.\n\n- **Complex Handover Support**: A receiving hospital or specialist reviewer benefits from visual context that would be difficult to reconstruct from text alone.\n\n- **Escalation to Formal Evidence Handling**: An artefact first captured for clinical context can be promoted into the broader evidence and chain-of-custody workflow if the case later requires it.\n\n## Integration\n\n- **Electronic Patient Care Report Clinical Workspace**: Scene artefacts are reviewed in the same encounter context as the rest of the patient record.\n\n- **Mobile Capture Surfaces**: Field users can collect visual context without leaving the clinical workflow for a separate app.\n\n- **Hospital Handover and Specialist Review**: Visual material can support later handover and clinical review where the receiving team needs more than a written summary.\n\n- **Evidence Provenance and Audit Workflows**: Where a scene artefact moves beyond clinical context into formal evidence handling, it can join the platform's existing provenance and chain-of-custody services.\n\n## Open Standards\n\n- **Media Capture and Streams**: browser-based photo capture can rely on the standard web media device model.\n\n- **SVG 1.1**: scene sketches use an open vector format that remains portable across systems and review tools.\n\n- **IANA Media Types / RFC 6838**: uploaded artefacts use standard media typing so connected systems can process images, video, SVG, and documents consistently.\n\n- **HTTPS / TLS**: media upload and retrieval follow the platform's standard secure web transport baseline.\n\n- **JSON**: redaction metadata and capture descriptors use a structured, interoperable payload format.\n"}
