Abstract

Background: Evidence of the burden of suboptimal stroke care should expedite quality improvement. We aimed to estimate the health and economic impact of improving acute stroke management to best practice standards using Australia as a case study. Methods: Hospital performance in Australia was estimated using data from the National Stroke Audit of Acute Services 2013. The percentage of patients provided evidence-based therapies in all hospitals was compared to that achieved in the aggregate of top performing benchmark hospitals (that included between them, a minimum contribution of 15% of all cases audited). The number of additional patients who would receive therapies if this performance gap was rectified was applied to a standardized economic simulation model that comprised stroke rates and resource-use estimates from the North East Melbourne Stroke Incidence Study applied to the 2013 Australian population. Results: In 2013, 41,398 patients were estimated to have been hospitalized with stroke. If acute care was improved to that of Australian benchmarks, there would be an additional 15,317 patients accessing stroke units; 1960 receiving thrombolysis; and 4007 being treated with antihypertensive medication, 3082 with antiplatelet medication, 2179 with anticoagulant medication, and 3514 with lipid-lowering therapy. Approximately 9329 disability-adjusted life years could be avoided. This additional care provided would be cost effective at AUD 3304 per disability adjusted life year avoided. Conclusion: The benefits of reducing evidence–practice gaps in Australia are considerable. Further investment in initiatives to optimize hospital care is justified.
