RESUMEN
BACKGROUND: In the setting of a national audit of acute stroke services, we examined the delivery of thrombolytic therapy for ischaemic stroke and whether current practice was achieving safe outcomes and consistent delivery for patients. METHOD: Data obtained from the recent national stroke audit was compared against previous Irish audit, the most recent SSNAP UK stroke audit and the Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST) study. RESULTS: Thrombolysis was provided in 27 acute hospitals throughout Ireland during the period assessed with 82% (22/27) providing 24/7 access, the remaining sites using redirect policies. Decision to thrombolyse was made by stroke trained consultants in 63% (17/27) of units, with general physicians and emergency medicine consultants covering the other units. Thrombolysis rate for non-haemorrhagic stroke was 11% (n = 80/742, CI 95% ±2.23) versus a 1% rate in the 2008 audit. Sites receiving patients through a redirect policy had the highest thrombolysis rate, an average of 24%. Nearly 30% of cases were thrombolysed on the weekend. Eighty-three percent of cases were managed in a stroke unit at some time during admission versus 54% of the national total cases. Thirty-seven percent of patients were ≥80 years old. The mortality rate was 11.3% versus the national mortality rate for non-thrombolysed ischaemic strokes of 10% (p > 0.5), and this is comparable to the SITS-MOST 2007 study 3-month mortality rate of 11.3% (p > 0.5). CONCLUSION: Stroke thrombolysis is being effectively and safely provided in acute stroke services in Ireland despite regular involvement of non-specialist staff. There is still potential to improve thrombolysis rate.
