Stroke remains the third leading cause of death in Ireland and Western Europe, and the leading cause of severe, adult-onset physical disability. We report on patients aged 17 years and over who were treated in the 24 public hospitals that provide acute stroke care in Ireland and that admit more than 25 stroke cases annually. Data are typically collected by stroke services on behalf of the participating hospitals. In order to be included in the audit report, hospitals must have collected data on more than 80% of patients with a stroke. This year’s report incorporates data from the 23 participating hospitals that met the mandatory 80% coverage threshold; overall, despite the effects of the coronavirus disease 2019 (COVID-19) pandemic, coverage improved from 83% to 93% across the hospital system for patients with a stroke identified through the Hospital In-Patient Enquiry (HIPE) system as having been admitted with acute stroke, either ischaemic or haemorrhagic. The audit does not currently collect data on subarachnoid haemorrhage; however, we are exploring how these data may be effectively incorporated in future years’ audits. Because of the increased coverage, the number of individuals on whom data have been collected increased by more than 20% in 2020 from 2019. This important increase in coverage does appear to have led to substantial changes in proportional outcomes for most variables, but caution should be exercised in interpretation of minor changes from previous years.
