Validation of a German-language modified Rankin Scale structured telephone interview at 3 months in a real-life stroke cohort.

Publication date: Nov 30, 2023

The modified Rankin scale (mRS) at 3 months is established as the primary outcome measure in clinical stroke trials. Traditionally, the mRS is assessed through an unstructured face-to-face interview. This approach can be labor-intensive and lead to suboptimal inter-rater reliability. Recently, the Covid-19 pandemic made face-to-face contact even more challenging. To address these issues, we developed and validated a structured German-language questionnaire for mRS testing by telephone. In this prospective cohort study, we compared the mRS testing results of the standard face-to-face interview with those obtained in a structured interview by telephone using Cohen’s Kappa. At our tertiary care stroke center, we included 108 patients who underwent both assessments. In 80. 6% of cases (87/108) face-to-face and telephone interview reached identical scores. Linear weighted Kappa was 0. 82 (p
