The Procedure and ProcedureNotDone profiles represent the positive and negative statements for a procedure. To ensure instances retrieved meet negative intent, applications should check the status element as illustrated in this example:

define ProcedureNotDone:
  [Procedure] P
    where P.status = 'not-done'

The following example illustrates the use of the ProcedureNotDone profile:

define "No VTE Prophylaxis Device Applied":
  ["Procedure": "Device Application"] DeviceApplied
    where (DeviceApplied.usedCode in "Intermittent pneumatic compression devices (IPC)"
      or DeviceApplied.usedCode in "Venous foot pumps (VFP)"
      or DeviceApplied.usedCode in "Graduated compression stockings (GCS)"
    )
      and  DeviceApplied.status = 'not-done'
    return
      {
        id: DeviceApplied.id,
        requestStatusReason: DeviceApplied.statusReason,
        authoredOn: DeviceApplied.recorded()
      }

See the patterns page for implementation and usage patterns.

Examples

Both of these example instances meet measure intent for exclusion as defined in the following example CQL:

define "No VTE Prophylaxis Device Applied":
  ["Procedure": "Device Application"] DeviceApplied
    let DeviceNotDoneTiming: Global.GetExtension(DeviceApplied, 'qicore-recorded').value
    where (DeviceApplied.usedCode in "Intermittent pneumatic compression devices (IPC)"
      or DeviceApplied.usedCode in "Venous foot pumps (VFP)"
      or DeviceApplied.usedCode in "Graduated compression stockings (GCS)"
    )
      and  DeviceApplied.status = 'not-done'
    return {
      id: DeviceApplied.id,
      requestStatusReason: DeviceApplied.statusReason,
      authoredOn: DeviceNotDoneTiming
    }
