Time to acute stroke treatment in-hours was more than halved after the introduction of the Helsinki Model at Westmead Hospital

Abstract

Background: Management of acute ischaemic stroke is time critical. Reducing time to treatment with thrombolysis is strongly associated with improved outcomes in properly selected patients. However, there are barriers to ensuring timely treatment in the hospital setting.

Aim: To determine if simple, no-cost protocol changes could improve time to treatment for acute ischaemic stroke at a busy tertiary hospital.

Methods: Prospectively collected routine clinical data were compared retrospectively before and after a protocol change designed to mirror the successful model from Helsinki University Central Hospital. Consecutive patients who activated a 'code stroke' (presentation consistent with acute stroke, eligible for acute stroke therapy) during working hours were included.

Results: Prior to the protocol change, 143 patients activated a code stroke, and 30 patients received thrombolysis. Following the protocol change, 134 patients activated a code stroke, and 14 patients received thrombolysis. The median time to administer thrombolysis was reduced from 76 min (interquartile range 54-91) to 33 min (27-44), P < 0.01. The median time to perform diagnostic computed tomography was unchanged between the two groups, 23 (14-54) min versus 22 (9-49) min, P = 0.12. However, this was reduced on subgroup analysis of patients whose arrival was pre-notified by the ambulance service, 16 (9-22) min versus 8 (4-14) min, P < 0.01.

Conclusion: Time to treatment in acute stroke was dramatically improved with a simple intervention. This was achieved without a large stroke team or additional funding, making it highly accessible to other health services also seeking to improve their stroke service.
