formula

The ISTH-SCC BAT Score is calculated by the addition of the selected points (only symptoms and treatmentBEFOREandATdiagnosis should be considered): Distinction between 0 and 1 is of critical importance. Score 1 means that the symptom is judged as present in the patient’s history by the interviewer but does not qualify for a score 2 or more. * Consultation only: the patient sought medical evaluation and was either referred to a specialist or offered detailed laboratory investigation. ** E.g., 1 extraction/surgery resulting in bleeding (100%): the score to be assigned is 2; 2 extractions/surgeries, 1 resulting in bleeding (50%): the score to be assigned is 2; 3 extractions/surgeries, 1 resulting in bleeding (33%): the score to be assigned is 2; 4 extractions/surgeries, 1 resulting in bleeding (25%): the score to be assigned is 1. #If already available at the time of collection.

pearls

• Validated for use in adults and children, although sensitivity is lower in pediatric populations.
• Low sensitivity for acquired bleeding disorders.
• Validated in various inherited bleeding disorder populations, including von Willebrand disease, hemophilia, and platelet disorders. 

usecase

Can be used to evaluate patients with a suspected inherited bleeding disorder.

reasons

Assesses the presence and severity of bleeding symptoms. Can serve as a screening tool to determine which patients require additional laboratory evaluation.

next_advice

• Results may inform the need for further diagnostic workup in patients with a suspected inherited bleeding disorder.
  
  • Low scores are associated with a low likelihood of a bleeding disorder, and additional evaluation may not be warranted.
  • Elevated scores indicate an increased risk of bleeding; further evaluation for an underlying inherited bleeding disorder is appropriate (e.g., laboratory studies, specialty consultation).
• Results are not intended to be diagnostic but should be used as part of a comprehensive evaluation in conjunction with clinical judgment and specialty consultation.
