• Background Heavy menstrual bleeding (HMB) can be the first manifestation of an undiagnosed bleeding disorder (BD). Identifying a BD can be challenging in the adolescent age group. The utility of bleeding assessment tools (BAT) remains elusive in this population. Aim We evaluated the ability of the International Society on Thrombosis and Haemostasis‐BAT (ISTH‐BAT) in predicting a BD in adolescents referred for HMB to a multidisciplinary hematology clinic. Methods Two hundred adolescents with HMB underwent a standardized evaluation for BD. The clinical characteristics, laboratory data, and bleeding scores (BS) assessed using ISTH‐BAT were prospectively collected. Comparisons were made between patients based on the diagnosis of BD receiver operating characteristic (ROC) curve analyses of ISTH‐BAT were performed to assess its value for predicting BD. Results Overall, 33% (n = 67) of adolescents were diagnosed with a BD. The mean ISTH‐BAT BS was higher in BD as compared to those without (4.1 versus 3.1, P < .0001), but the mean menorrhagia‐specific scores did not differ (2.9 in both groups). The ISTH‐BAT demonstrated a modest discriminative ability as a screening tool to identify BD in girls with HMB with an area under the curve (AUC) of 0.71. The ROC analysis demonstrated that with increasing BS, the sensitivity decreased, but the specificity increased. At BS = 3, sensitivity was 88%, specificity 31%, and accuracy 50%; at BS = 5, sensitivity was 37%, specificity 94%, and accuracy was 75%. There was no change thereafter. Conclusion In adolescents with HMB, an ISTH‐BAT BS of >4 instead of the established cut‐off of >2 in children is highly specific in predicting a BD.
