Abstract TP398: Stroke prevention opportunities being missed: the Australian Stroke Clinical Registry experience.
Introduction: Stroke utilizes a large portion of hospital resources. Little is known about the frequency of contacts with hospitals prior to first-ever stroke and potentially missed opportunities for stroke prevention. In addition, re-admissions may indicate failed secondary prevention.
Hypothesis: Many patients have had a presentation or admission to hospital in the year prior to a first-ever stroke event.
Methods: Data from the prospective, national Australian Stroke Clinical Registry (AuSCR) obtained between 15 June 2009 and 31 December 2010 from a large hospital in Melbourne, Victoria (Australia) were linked to the Victorian government emergency department (ED) and hospital discharge datasets for a 3 year ‘look-back’ period and any re-presentation up until February 2011 using stepwise deterministic linkage methods. Descriptive statistics are presented.
Results: Matched linkage to ED (731/788) and hospital discharge (736/788) datasets was achieved in 93% of AuSCR registrants, of whom 513 were first-ever strokes (51% male, average age 74 [±16] years, 82% ischemic). Prior to the first-ever stroke, 221 (47%) registrants had ED presentations and 283 had a hospital admission on average 2.9 months before stroke. The mean number of ED presentations within 3 years of AuSCR registration for a first-ever event was 2.1 (SD 1.6); and 48/466 (10%) occurred in the month prior to stroke. Among first-ever stroke registrants, 200 were re-admitted on average within 5 months following discharge; 3.5% for recurrent stroke/TIA.
Conclusion: Contact with hospitals was common (~50%) before first stroke, raising opportunities to screen and intervene in people at risk of stroke. As one in 5 hospital re-admissions is for recurrent stroke, a closer monitoring of secondary prevention measures in the early post-discharge period may be warranted.
