Study Aim
The aim of this Delphi study is to develop consensus‑based methodological standards for analysing and reporting routinely collected health data to calculate core health outcome measures for stroke.
The initial focus is on defining internationally applicable methods for:
Short‑ and long‑term mortality after stroke
Short‑ and long‑term hospital readmissions after stroke
These standards will support transparent, rigorous, and comparable reporting of stroke outcomes across health systems and research contexts.
What Does Participation Involve?
Participants will be invited to complete 2–3 rounds of online Delphi surveys, each taking approximately 15–20 minutes.
Surveys will involve:
Rating the importance of proposed methodological standards
Providing optional qualitative feedback
Surveys are anonymous, focused on methodological reporting, and do not include highly sensitive personal questions. Participants may be contacted up to two additional times, depending on consensus achieved in earlier rounds.
Who Can Participate?
Participation is open to individuals with an understanding of the clinical condition of stroke and at least 5 years of experience working with routinely collected health data in any capacity (e.g., data analysis, methodological development, advisory roles, clinical interpretation, governance, or project management).
Participants must be able to complete surveys in English.
Why a Delphi Study?
The Delphi method uses structured, iterative, and anonymous surveys to minimise bias, promote equal contribution, and build consensus—particularly where empirical evidence or standardised methods are lacking. It is widely used in the development of core outcome sets and methodological standards.
