Society of Neurointerventional Surgery suggested stroke process time metrics*
| Action | Time (min)† | SNIS ‘ideal’ time‡ |
|---|---|---|
| Door to physician | <10 | On arrival |
| Door to NCCT/CTA | <25 | On arrival |
| Door to stroke team | <15 | <10 min |
| Door to NCCT interpretation | <45 | <15 min |
| Door to CTA interpretation | N/A | <20 min (or 10 min after acquisition) |
| Door to IV tPA | <60 | <30 min |
| Door to CTP/MRI (optional) | N/A | <30 min |
| CSC Door to puncture | N/A | <60 min |
| CSC Door to recanalization | N/A | <90 min |
| PSC picture to CSC puncture§ | N/A | <90 min |
*Assuming emergency medical services prenotification. †AHA 2013 standard.
‡SNIS ideal.
§Assuming direct transfer to biplane neuroangiography suite when feasible.
