If the patient is admitted to a team and subsequently receives IA intervention at the same team then the record should be started as normal by the admitting hospital.
If a patient first presents at one hospital but is then transferred to another specialist IA intervention centre it should be the specialist IA centre that starts the SSNAP record. Data taken from the point of arrival at the first hospital should be shared with the specialist IA centre, this will most likely comprise of:
- Time of arrival at the first hospital (to be recorded as time of arrival at the thrombectomy centre)
- Scan time
- NIHSS on arrival
- Times of any other specialist assessments performed
The team performing the thrombectomy should enter this data as if the patient first arrived at their team. We understand that teams that refer patients for thrombectomy off site will be concerned that these patients will not be included in their team-centred 72 hour results. However it is worth reiterating that it is expected that the number of cases will be small. If such patients are transferred back to the first hospital within 72 hours then the record will be analysed for both teams in the patient-centred 72 hour results.
