Characterizing the Impact and Treatment of Reproductive Tract Bleeding on Women and Post-menarchal Girls With Bleeding Disorders

Characterizing the impact and treatment of reproductive tract bleeding on women and post-menarchal girls with bleeding disorders.

Objectives: This is a cross-sectional observational study of women and girls (WG) with bleeding disorders enrolled in the American Thrombosis and Hemostasis Network (ATHN) dataset. Based on the investigators' study of currently available data of WG with bleeding disorders in the ATHNdataset, the investigators hypothesize that the information currently captured in the core data elements of the ATHNdatasest does not adequately capture data specific to WG with bleeding disorders. Further, the investigators hypothesize that it is feasible for Hemophilia Treatment Centers (HTCs) to include data points specific to WG with bleeding disorder when enrolling participants in the ATHNdataset. This hypothesis will be evaluated through the following specific aims:

Specific Aim 1: Characterize reproductive tract bleeding in a cohort of WG with bleeding disorders cared for at US HTCs.

Specific Aim 2: Characterize the treatment strategies for and the impact of heavy menstrual bleeding in a cohort of females with bleeding disorders cared for at HTCs.

Specific Aim 3: Evaluate the feasibility of adding female specific core data points to the ATHNdataset.

This is a multi-center, cross-sectional study of women and girls with bleeding disorders receiving care at Hemophilia Treatment Centers (HTCs). To further characterize this population, WG who receive care at federally funded US HTCs will be approached regarding participation. Following assent and/or consent, participants will be asked to complete a series of forms. In order to assess their bleeding symptoms, they will complete the self-BAT (Bleeding Assessment Tool) as well as the Menstrual Bleeding Questionnaire (MBQ). In order to assess their quality of life, they will complete the PROMIS-29 quality of life inventories. Patients may be contacted if they miss a question on any of these forms. Phone call should take no more than 15 minutes. Study staff will complete an intake form which includes data regarding bleeding disorder diagnosis as well as treatment, using information obtained from the patient, chart review, and the ATHNdataset.
