Background: Value-based healthcare delivery is a strategy to align patients, providers, and payers toward improving outcomes while reducing costs. We sought to define an international standard set of patient-centered, stroke health outcomes.

Methods: We assembled an international expert panel representing patients, advocates, and physician experts in stroke outcomes, stroke registries, global health, epidemiology, and rehabilitation. A modified Delphi process was used to reach consensus recommendations for a Standard Set of outcome measures, baseline risk adjustment variables, and included populations for use in both low and high income countries.

Results: Patients presenting to a hospital with ischemic stroke or intracerebral hemorrhage evaluated with brain imaging were selected as the required included population, with optional inclusion of transient ischemic attacks. Because of differences in ascertainment and imaging modalities, duration of symptoms and type of imaging are collected to allow for comparisons of homogeneous groups across various countries and practice settings. Basic functional status is assessed at prestroke baseline, index admission, discharge, 90 days, and 1 year thereafter. Co-morbidities and stroke severity are collected for risk adjustment. Symptomatic intracerebral hemorrhage after thrombolysis is the only complication captured, and many measures reflect patient-reported quality of life outcomes and priorities captured in the Patient Reported Outcomes Measurement Information System 10-question short form (PROMIS-10) and elements from existing registries.

Conclusions: The stroke measure Standard Set is proposed for implementation to permit meaningful comparisons and increase value of stroke care worldwide using a simple, pragmatic strategy.
