Establishment of an internationally agreed minimum data set for acute telestroke

Abstract

Introduction: Globally, the use of telestroke programs for acute care are expanding. Currently, a standardised set of variables for enabling reliable international comparisons of telestroke programs does not exist. This study aimed to establish a consensus-based, minimum data set for acute telestroke to enable the reliable comparison of programs, clinical management and patient outcomes.

Methods: An initial scoping review of variables was conducted, supplemented by reaching out to colleagues leading some of these programs in different countries. An international expert panel of clinicians, researchers, and managers (n=20) from the Australasia Pacific region, United States of America, United Kingdom and Europe was convened. A modified-Delphi technique was used to achieve consensus via on-line questionnaires, teleconferences and via email.

Results: Overall, 533 variables were initially identified and harmonised into 159 variables for the expert panel to review. The final dataset included 110 variables covering three themes (service configuration, consultations, patient information) and 12 categories: 1) Details about telestroke network/program (n=12), 2) Details about initiating hospital (n=10), 3) Telestroke consultation (n=17), 4) Patient characteristics (n=7), 5) Presentation to hospital (n=5), 6) General clinical care within first 24 hours (n=10), 7) Thrombolysis treatment (n=10), 8) Endovascular treatment (n=13), 9) Neurosurgery treatment (n=8), 10) Processes of care beyond 24 hours (n=7), 11) Discharge information (n=5), 12) Post-discharge and Follow-up data (n=6).

Discussion: The acute telestroke minimum dataset provides a recommended set of variables to systematically evaluate acute telestroke programs in different countries. Adoption is recommended for new and existing services.
