Adherence to Clotting Factor Treatment and Association with Bleeding and Health-Related Quality of Life in Persons with Hemophilia

Introduction:Measuring patient adherence to prophylactic treatment with clotting factor in persons with hemophilia includes both subjective and objective measurements. There are limited studies conducted in adherence research using objective measures and a few studies revealed lack of correlation between subjective and objective adherence measurement. The study objectives are 1) to develop an objective adherent measurement; and 2) to assess it's association with bleeding and health-related quality of life (HRQoL) using the data collected from the Hemophilia Utilization Group Study Part VI (HUGS VI), which was an observational, non-interventional study investigating adherence to factor replacement therapy among persons with hemophilia A or B.
