Included: all patients who were thrombolysed are included in this indicator.
| Excluded: all patients who were not thrombolysed are excluded from this indicator |
Numerator = the number of patients who were thrombolysed within and including 60 minutes.
Denominator = the total number of patients who were thrombolysed.
To calculate whether a patient is included in the numerator:
For newly arrived patients, the difference between the date and time patient was thrombolysed (Q 2.7) and date and time of arrival (Q 1.13) must be between 0 minutes and 60 minutes.
For patients already in hospital at the time of their stroke (Q 1.10 is ‘Yes’), the difference between the date and time patient was thrombolysed (Q 2.7) and the date and time of symptom onset (Q 1.11) must be between 0 minutes and 60 minutes.
Cohort percentage:
| For team-centred | For patient-centred |
| All patients who were thrombolysed in the team-centred 72h cohort | All patients who were thrombolysed in the patient-centred 72h cohort |
Example
Patient K arrived (clock start) at hospital at 12:15 on Friday. They were thrombolysed at 12:40 that same day. Patient K has achieved the indicator because 12:15-12:40 = 25 minutes.
Patient L had an onset in hospital (clock start) at 16:01 on Friday. They were thrombolysed at 16:37 that same day. Patient L has achieved the indicator because 16:01-16:37 = 36 minutes.
Patient M arrived (clock start) at hospital at 10:15 on Tuesday. They were thrombolysed at 11:16 that same day. Patient M has not achieved the indicator because 10:15-11:16 = 61 minutes.
Patient N arrived (clock start) at hospital at 20:08 on Saturday. They were not thrombolysed. Patient N is excluded because they were not thrombolysed.
Patient O arrived (clock start) at hospital at 08:10 on Tuesday. They were thrombolysed at 09:30 that same day. Patient O has not achieved the indicator because 08:10-09:30 = 80 minutes.
Therefore the cohort percentage is 0.50 or 50% or
