BackgroundThe Registry of Stroke Care Quality (RES‐Q) is a world‐wide quality improvement data platform that captures performance and quality measures enabling standardized comparisons of hospital care. The aim of this study was to determine if, and how, RES‐Q data are used to influence stroke quality improvement; and identify support and educational needs of clinicians in use of RES‐Q data to improve stroke care.MethodsA cross‐sectional self‐administered online survey was administered (October 2021‐February 2022). Participants were RES‐Q hospital local coordinators responsible for stroke data collection. Descriptive statistics are presented.ResultsSurveys were sent to 1463 hospitals in 74 countries; responses received from 358 hospitals in 55 countries (response rate 25%). RES‐Q data were used ‘always’ or ‘often’ to: develop quality improvement initiatives (n=213, 60%); track stroke care quality over time (n=207, 58%); improve local practice (n=191, 53%); and benchmark against evidence‐based policies, procedures and/or guidelines to identify practice gaps (n=179, 50%). Formal training in use of RES‐Q tools and data were the most frequent support needs identified by respondents (n=165, 46%). Over half ‘strongly agreed’ or ‘agreed’ that to support clinical practice change, education is needed on: i) using data to identify evidence‐practice gaps (n=259, 72%) and change clinical practice (n=263, 74%), and ii) quality improvement science and methods (n=255, 71%).ConclusionRES‐Q data are used for monitoring stroke care performance. However, to facilitate its optimal use, effective quality improvement methods are needed. Educating staff in quality improvement science may develop competency and improve use of data in practice.
