National survey of management of transient ischaemic attack in Australia: Take Immediate Action

Abstract

Objective: To understand the current organisation of services for people with transient ischaemic attack (TIA) and the processes of assessment and management across Australian hospitals. Design and setting: Cross-sectional survey in 2008 of 134 Australian hospitals, mostly urban centres that treat large numbers of stroke patients. Main outcome measures: Survey questions covered assessment, early management and follow-up practices, as well as organisation of services for TIA. Results: Seventy-four hospitals (55%) responded: 47 (64%) reported access to a stroke unit, and 19 (26%) to a specialist clinic for TIA. Initial assessment included blood tests, electrocardiogram and brain computed tomography at most sites (92%–94%), and carotid imaging at more than half (65%), but magnetic resonance imaging at only 3% of sites. A tool to stratify the risk of subsequent stroke was used at 38 sites (51%), more commonly in hospitals with a stroke unit than in those without such a unit (64% v 30%; P = 0.005). Treatment was initiated at the initial assessment at 42 sites (58%), more commonly at stroke unit than non-stroke unit sites (68% v 37%; P = 0.007). Formalised policies for management of TIA patients were used at 38 sites (54%), with clear differences between sites with a stroke unit and those without (70% v 25%; P < 0.001). Conclusion: Access to rapid assessment and management services for TIA varies considerably between Australian hospitals. The presence of organised stroke care at a hospital leads to improved processes of care for patients presenting with TIA.
