Pain in Patients With Congenital Coagulopathies

Introduction. The development of joint hemorrhages in patients with congenital coagulopathies favor the development of an intra-articular, degenerative and progressive lesion (hemophilic arthropathy). Pain is one of the main clinical manifestations of hemophilic arthropathy and is related to the development of disability and a worse quality of life. Objective. Observe the characteristics of pain, coping models and the perception of quality of life in patients with congenital coagulopathies. Study design. Observational, cross-sectional and multi-center study. Method. 80 patients with congenital coagulopathies (hemophilia A and B, and von Willebrand's disease), of legal age, will be included in the study. Patients will be recruited in six centers, from different regions of Spain. The study variables and measurement instruments used will be: pain perception (numerical pain scale, Tampa Scale of kinesiophobia and Pain Catastrophizing Scale); perception of quality of life (Short Form -36 questionnaires); anxiety (State-Trait Anxiety Questionnaire); coping strategies (Coping Strategy Questionnaire); and disease perception (Illness behaviour questionnaire and Revised Illness Perception Questionnaire). A descriptive statistical analysis of the dependent and independent variables will be carried out. In the same way, the correlations between the variables and the characteristics of the subjects will be analyzed according to age, the type of coagulopathy and the degree of sequelae. Expected results. Observe the characteristics of pain, its coping models and its implication in the quality of life in patients with congenital coagulopathies, and evaluate the independent variables related to the perception of pain.
