OCS-CARE: Post-Stroke Cognitive Assessment Data from 821 Patients in England

Nele Demeyere's OCS-CARE dataset contains clinical trial data from 821 post-stroke patients recruited from 37 hospital or rehabilitation sites in England. The study randomized patients to receive either the Oxford Cognitive Screen (OCS) or the Montreal Cognitive Assessment (MoCA) at baseline, with 467 patients completing a 6-month follow-up assessment. Primary outcome measures include the Stroke Impact Scale (SIS) and change in stroke severity (NIHSS), with a secondary outcome of cognitive performance change.

Use Cases

• Compare the effectiveness of the OCS versus the MoCA for cognitive assessment based on the randomized controlled trial design.
• Analyze changes in stroke severity and patient-reported impact over a 6-month period based on the NIHSS and SIS outcome measures.
• Model cognitive performance trajectories from baseline to follow-up based on the secondary outcome data.
• Investigate site-level variation in patient outcomes based on recruitment from 37 different locations.

Strengths

• Data from 821 patients provides a substantial sample size for analysis.
• Multi-site recruitment from 37 different hospital or rehabilitation sites in England suggests geographic diversity.
• Longitudinal design with 467 patients completing a 6-month follow-up allows for change-over-time analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the final dataset is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
