## Part 1: History of Present Illness (HPI) – OLDCARTS Framework
i-Human scores you on **efficiency** in history-taking. Use the
OLDCARTS mnemonic and ask targeted questions:
| Component | Key Questions | Clinical Reasoning |
|-----------|---------------|-------------------|
| **Onset** | "When did the rash first appear? Was it sudden or
gradual?" | Sudden onset suggests acute allergic reaction or contact
dermatitis; gradual, relapsing course points toward atopic dermatitis
|
| **Location** | "Where did it start? Where is it now? Has it
spread?" | Flexural distribution (antecubital/popliteal fossae) is
classic for atopic dermatitis |
| **Duration** | "How long have you had this?" | Typically 2-3
weeks in this case presentation |
