Included: all patients are included in this indicator
| Excluded: no patients are excluded from this indicator |
Numerator = the number of patients who were scanned in 12 hours or less.
Denominator = all the patients in the cohort. Patients who are not scanned are only included in the denominator.
To calculate whether a patient is included in the numerator:
For patients newly arriving at hospital, the difference between the date and time of arrival (Q 1.13) and the date and time of scan (Q 2.4) must be less than or equal to 720 minutes.
For patients already in hospital at the time of their stroke (Q 1.10 is ‘Yes’), the difference between the date and time of symptom onset (Q 1.11) and the date and time of scan (Q 2.4) must be less than or equal to 720 minutes.
Cohort percentage:
| For team-centred | For patient-centred |
| All patients in the team-centred 72h cohort | All patients in the patient-centred 72h cohort |
Example
Patient X arrived (clock start) at hospital at 18:57 on Tuesday. They were then scanned at 19:16 that same day. Patient X has achieved the indicator because 19:16-18:57 = 19 minutes.
Patient Y arrived (clock start) at hospital at 12:15 on Friday. They were then scanned at 13:16 that same day. Patient Y has achieved the indicator because 13:16-12:15 = 61 minutes.
Patient Z onset in hospital (clock start) at 20:08 on Saturday. They were not scanned. Patient Z has not achieved the indicator because they were not scanned.
Therefore the cohort percentage is 0.67 or 67% or
