Abstract

Background: Bleeding questionnaires are effective and recommended screening tools for potential bleeding disorder, but healthcare practitioner–administered bleeding assessment tools (expert-ISTH-BATs) are time-consuming. A patient-administered ISTH-BAT (self-ISTH-BAT) has been developed and validated. We translated, validated, and evaluated the usability of self-ISTH-BAT. Methods: We conducted a forward–backward translation of self-ISTH-BAT from English to Danish. Expert-ISTH-BAT and Danish self-ISTH-BAT were administered to 106 random individuals aged ≥18 years attending Odense University Hospital between August and November 2020 for elective blood sampling. Results comprise a score of bleeding symptoms. Results: Mean age of included individuals were 49 years (range: 18-83), and 59% were female. Median self-ISTH-BAT score was 2 (range: 0-18) and 1 (range: 0-22) for expert-ISTH-BAT (P =.09). All organ systems had ≥90% exact score agreement between expert-ISTH-BAT and self-ISTH-BAT, except gastrointestinal bleeding (77%) and other bleedings (72%). We found an acceptable correlation (r2 =.80) between expert-ISTH-BAT and self-ISTH-BAT. The self-ISTH-BAT had 82% sensitivity and 89% specificity at the recommended cutoff for expert-BAT (female:<6; male:<4). At this cutoff, 10 had abnormal self-ISTH-BAT scores with normal expert-ISTH-BAT. Three (3%) had normal self-ISTH-BAT with abnormal expert-ISTH-BAT. Conclusion: Self-ISTH-BAT can replace expert-ISTH-BAT as a screening tool for bleeding disorders in Danish individuals as only 3% were not identified with the self-ISTH-BAT tool.
