Generation and optimization of the self-administered bleeding assessment tool and its validation as a screening test for von Willebrand disease.

ABSTRACT:

Introduction/aim

Our aim was to generate, optimize and validate a self-administered bleeding assessment tool (self-BAT) for von Willebrand disease (VWD).

Methods

In Phase 1, medical terminology in the expert-administered International Society on Thrombosis and Haemostasis (ISTH)-BAT was converted into a Grade 4 reading level to produce the first version of the Self-BAT which was then optimized to ensure agreement with the ISTH-BAT. In Phase 2, the normal range of bleeding scores (BSs) was determined and test-retest reliability analysed. In Phase 3, the optimized Self-BAT was tested as a screening tool for first time referrals to the Haematology clinic.

Results

Bleeding score from the final optimized version of the Self-BAT showed an excellent intra-class correlation c
