Included: all patients are included in this indicator, except those who are either medically unwell until time of screening or refused to be screened.
| Excluded: patients who are medically unwell until time of screening or refused to be screened (ie patients where Q 2.10.1 is answered ‘Patient refused’ or ‘Patient medically unwell until time of screening’) are excluded from this indicator |
Numerator = the number of patients who were given a swallow screen within 4h of clock start.
Denominator = all the applicable patients in the cohort. Patients who are applicable but not given a swallow screen are included in the denominator.
To calculate whether a patient is included in the numerator:
For newly arrived patients, the difference between the date and time of first swallow screen (Q 2.10) and date and time of arrival (Q 1.13) must be greater than 0 minutes and less than or equal to 240 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 first swallow screen (Q 2.10) and the date and time of symptom onset (Q 1.11) must be greater than 0 minutes and less than or equal to 240 minutes.
Cohort percentage:
| For team-centred | For patient-centred |
| All patients in the team-centred 72h cohort except those who are medically unwell until time of screening or refused to be screened | All patients in the patient-centred 72h cohort except those who are medically unwell until time of screening or refused to be screened |
Example
Patient W arrived (clock start) at hospital at 10:00 on Monday. They were medically unwell until 10:00 on Friday. Patient W is excluded from the indicator because they were medically unwell until the time of screening.
Patient X arrived (clock start) at hospital at 15:00 on Tuesday. They were given a first swallow screen at 16:30 that day. Patient X has achieved the indicator because 16:30 - 15:00 = 90 minutes
Patient Y arrived (clock start) at hospital at 12:15 on Saturday. They were given a swallow screen at 17:15 that day. Patient Y has not achieved the indicator because 17:15 – 12:15 = 300 minutes
Patient Z arrived (clock start) at hospital at 20:08 on Thursday. They were not given a swallow screen so have not achieved the indicator.
Therefore the cohort percentage is 0.33 or 33% or
