For patients in whom hemophilia is suspected, inquire about the following:

  • History of hemorrhage disproportionate to trauma
  • History of spontaneous hemorrhage
  • Bleeding disorders in the family
  • Concomitant illness (especially those associated with acquired hemophilia, such as chronic inflammatory disorders, autoimmune diseases, hematologic malignancies, and allergic drug reactions)
  • Recent pregnancy

For individuals with documented hemophilia, ascertain the type of deficiency (eg, factor VIII [FVIII], FIX, von Willebrand), degree of factor deficiency, known presence of inhibitors, and HIV/hepatitis status. For patients with mild-to-moderate disease, determine responsiveness to desmopressin acetate (DDAVP). [8]
