ISTH-SCC Bleeding Assessment Tool (BAT)

Description

Calculates the ISTH-SCC BAT score to screen for inherited bleeding disorders (e.g., von Willebrand disease, platelet disorders). The tool evaluates bleeding severity across 13 domains, assigning points (0-4) based on the level of medical intervention required.

Usage

                       oral_cavity_score, gi_bleeding_score, pulmonary_score,
                       hematuria_score, menorrhagia_score, postpartum_hemorrhage_score,
                       surgery_bleeding_score, dental_bleeding_score,
                       cns_bleeding_score, other_bleeding_score, age, sex)

cns_bleeding_score	Numeric (0-4). Score for intracranial/CNS bleeding (usually 0 or 4).
other_bleeding_score	Numeric (0-4). Score for other types (e.g., ovulation, muscle/joint).
age	Numeric. Patient age in years.

Details

General Scoring Key: 0 = No symptoms 1 = Reported, no medical attention 2 = Medical attention (consultation) 3 = Surgical intervention, packing, cauterization, or antifibrinolytics 4 = Blood transfusion, replacement therapy, or desmopressin

Abnormal Cutoffs: Children (<18y): >= 3 Adult Males: >= 4 Adult Females: >= 6

Value

A list containing:

ISTH_BAT_Score	The calculated total score.
Interpretation	Screening result based on age/sex-specific cutoffs.
Cutoff_Applied	The threshold used for the interpretation.
