# Conditions

Conditions (FHIR `Condition`) represent clinical diagnoses, problems, and health concerns. They support the problem list, encounter diagnoses, staging, and evidence tracking throughout the condition lifecycle.

## Record a Diagnosis

```ts theme={null}
const { data: condition } = await clinik.conditions.create({
  patientId: 'pt_abc123',
  clinicalStatus: 'active',
  verificationStatus: 'confirmed',
  category: ['encounter-diagnosis'],
  severity: 'moderate',
  code: {
    system: 'http://hl7.org/fhir/sid/icd-10-cm',
    code: 'E11.9',
    display: 'Type 2 diabetes mellitus without complications',
  },
  encounterId: 'enc_visit456',
  onsetDateTime: '2023-08-15',
  recordedDate: '2024-01-10',
  recorderId: 'pract_dr456',
  note: 'Patient presents with elevated HbA1c of 7.8%. Starting metformin.',
});
```

## Problem List Entry

```ts theme={null}
const { data: problem } = await clinik.conditions.create({
  patientId: 'pt_abc123',
  clinicalStatus: 'active',
  verificationStatus: 'confirmed',
  category: ['problem-list-item'],
  code: {
    system: 'http://snomed.info/sct',
    code: '38341003',
    display: 'Hypertension',
  },
  onsetString: 'Diagnosed in 2020',
  stage: [
    { summary: 'Stage 2', type: 'clinical' },
  ],
  evidence: [
    { code: ['Elevated blood pressure readings'] },
  ],
});
```

## Condition with Staging and Evidence

```ts theme={null}
const { data: cancer } = await clinik.conditions.create({
  patientId: 'pt_abc123',
  clinicalStatus: 'active',
  verificationStatus: 'confirmed',
  category: ['problem-list-item'],
  severity: 'severe',
  code: {
    system: 'http://snomed.info/sct',
    code: '254837009',
    display: 'Malignant neoplasm of breast',
  },
  bodySite: ['Left breast'],
  onsetDateTime: '2024-02-01',
  recordedDate: '2024-02-15',
  stage: [
    { summary: 'Stage IIA', type: 'pathological' },
  ],
  evidence: [
    { code: ['Mammography findings', 'Biopsy results'] },
    { detailIds: ['obs_mammo123', 'obs_biopsy456'] },
  ],
});
```

## Mark a Condition as Resolved

```ts theme={null}
await clinik.conditions.update(condition.id, {
  clinicalStatus: 'resolved',
  abatementDateTime: '2024-06-01',
  note: 'HbA1c normalized. Condition resolved with lifestyle changes.',
});
```

## Search Conditions

```ts theme={null}
// Active conditions for a patient
const { data } = await clinik.conditions.search({
  patientId: 'pt_abc123',
  clinicalStatus: 'active',
});

// Problem list items
const { data: problems } = await clinik.conditions.search({
  patientId: 'pt_abc123',
  category: 'problem-list-item',
});

// Search by ICD-10 code
const { data: diabetes } = await clinik.conditions.search({
  code: 'E11.9',
});
```

## Clinical Status Lifecycle

| Status       | Description                             |
| ------------ | --------------------------------------- |
| `active`     | Condition is currently active           |
| `recurrence` | Condition has recurred after resolution |
| `relapse`    | Condition has relapsed after remission  |
| `inactive`   | Condition is no longer active           |
| `remission`  | Condition is in remission               |
| `resolved`   | Condition is fully resolved             |
