Abstract
INTRODUCTION: Stroke is a leading cause of death and disability, with the administration of recombinant transcriptase-plasminogen activator (rtPA) improving outcomes in a time-dependent manner. Only 52.3% of eligible stroke patients at our institution received rtPA within 60 minutes of arrival. We aimed to improve the percentage of acute stroke patients receiving rtPA within 60 minutes of arrival at the emergency department (ED). METHODS: This study presents results from the first year of a clinical practice improvement project that implemented quality improvement interventions. The primary outcome measure was percentage of acute ischaemic stroke patients receiving rtPA within 60 minutes of arrival at the ED. Secondary outcome measures included components of total door-to-needle (DTN) time and factors for delay to thrombolysis. Interventions were establishment of standardised acute stroke activation guidelines, screening question at ED registration, prehospital notification of stroke activation, public education, scripting for thrombolysis consent and easy access to equipment. RESULTS: The percentage of patients thrombolysed within 60 minutes increased to 60.6% (p = 0.27), and DTN time decreased from 59 minutes to 54.5 minutes (p = 0.15). This was attributable to reduced door-to-physician time, door-to-imaging time and decision time, although the results were not significant. There was no significant increase in symptomatic intracranial haemorrhage or mortality secondary to stroke. Length of stay was significantly reduced by 1.5 days (p < 0.048). CONCLUSION: The interventions resulted in an increasing but non-significant trend of acute stroke patients receiving thrombolysis within 60 minutes. Outcomes will be monitored for a longer duration to demonstrate trends and sustainability.
