Injury and Harm Valuation Standard (IHVS)

Purpose

IHVS is a structured standard for describing and valuing harms in a consistent way. It defines domains, code families, evidence expectations, and report formats. It is not legal advice and does not replace clinical assessment.

Version

• IHVS Standard version: v1.0 (site publication)
• IHVS Evaluate pack format: IHVS-EVAL-v1.0
• Storage rule: local-only on user device; export/import to move between devices.

Domains and code families

• INC — Incident / event characteristics
• PSY — Psychological / cognitive impacts
• PHY — Physical impacts
• LIB — Liberty and restriction impacts
• EVD — Evidence and sources

Code syntax: DOMAIN.SUBDOMAIN.TAG.NUM (example: PSY.SLEEP.01).

Evidence expectations

The standard records what evidence exists and what preservation actions may be needed (e.g., CCTV retention windows). It does not assume evidence quality; it records it.

Core evidence classes

• Contemporaneous documents (letters, emails, notes)
• Official records (case notes, logs, decision records)
• Media (photos, audio, video, CCTV)
• Witnesses (staff, public, family, professionals)

Stacking and duplication

Tick-box codes are descriptive. In valuation, avoid double-counting: (1) select codes that describe distinct harms; (2) treat repeated descriptions of the same harm as corroboration rather than additive value.

Governance

• Standard updates are versioned; previous versions remain accessible.
• Evaluate packs include their format version to support forward compatibility.
• Local-only rule is mandatory for this site section.
