# Device Use Statements

> Record when and how devices are used on patients.

# Device Use Statements

Device Use Statements (FHIR `DeviceUseStatement`) record the actual use of a device on a patient. While Device Requests capture the order, Device Use Statements capture what actually happened.

## Record Device Use

```ts theme={null}
const { data: statement } = await clinik.deviceUseStatements.create({
  status: 'active',
  patientId: 'pt_abc123',
  deviceId: 'dev_pacemaker789',
  timingPeriod: {
    start: '2024-01-15',
  },
  bodySite: 'Left chest wall',
  reasonCode: ['Bradycardia management'],
  sourceId: 'prac_dr456',
  note: 'Dual-chamber pacemaker implanted, functioning normally',
});
```

## Record Completed Device Use

```ts theme={null}
const { data } = await clinik.deviceUseStatements.create({
  status: 'completed',
  patientId: 'pt_abc123',
  deviceId: 'dev_cgm456',
  timingPeriod: {
    start: '2024-02-01',
    end: '2024-02-14',
  },
  recordedOn: '2024-02-15',
  reasonCode: ['Glucose monitoring for diabetes management'],
  note: '14-day CGM cycle completed. Average glucose: 142 mg/dL',
});
```

## Update Statement Status

```ts theme={null}
await clinik.deviceUseStatements.update(statement.id, {
  status: 'completed',
  note: 'Pacemaker removed due to device recall',
});
```

## Search Device Use Statements

```ts theme={null}
// Find all active device use for a patient
const { data } = await clinik.deviceUseStatements.search({
  patientId: 'pt_abc123',
  status: 'active',
});

// Find all uses of a specific device
const { data: uses } = await clinik.deviceUseStatements.search({
  deviceId: 'dev_pacemaker789',
});
```

## Status Values

| Status      | Description                           |
| ----------- | ------------------------------------- |

| `completed` | Device use has ended                  |
| `on-hold`   | Device use is temporarily paused      |
| `intended`  | Device use is planned but not started |
| `stopped`   | Device use was stopped early          |
