Assessing the Risk of Bleeding:
The Pediatric Bleeding Questionnaire [PBQ]

Introduction


The PBQ was developed to screen children for von Willebrands Disease. 

In children with a PBQ score of 3 and predicted to have VWD, the sensitivity was 97.2% with a specificity of 97.1%.  The positive predictive value was 48.6%, and the negative predictive value was 99.9%.

The variables evaluated in the PBQ are summarised below. Each variable apart from CNS bleeds are scored from 0-4 but in addition three variables [Dental extractions, Surgery and Post-partum] may receive a score of -1 if an individual has undergone these procedures/events with no bleeding problems. A score of 4 represents the most severe symptoms.
