Association of Prophylactic Treatment With Treatment Burden and Psychosocial Variables in Patients With Hemophilia

Sponsor: Investigación en Hemofilia y Fisioterapia

Summary

Introduction: Hemophilia is a congenital coagulopathy characterised by recurrent haemarthrosis, leading to chronic arthropathy and functional impairment. Prophylactic treatment with extended half-life (EHL) or short half-life (SHL) clotting factor concentrates is the most effective strategy for preventing these episodes. EHL products have demonstrated haemostatic efficacy, with a lower frequency of infusions, potentially reducing the treatment burden, although their psychosocial impact has not yet been sufficiently explored. Objectives: To evaluate the association between perceived treatment burden and psychosocial variables such as self-efficacy, adherence, sleep quality and health locus of control, depending on the type of treatment received (EHL or SHL). Methods. Multicentre, ambispective cohort study. A total of 114 patients with haemophilia A or B undergoing EHL or SHL prophylactic treatment will be included. The primary variable will be treatment burden (Treatment Burden Questionnaire). Secondary variables will be perceived self-efficacy (General Self-Efficacy Scale), adherence (Torres scale), sleep quality (Pittsburgh Sleep Quality Index), treatment adherence (Torres Questionnaire) and health locus of control (Multidimensional Health Locus of Control). Potential confounding variables will include sociodemographic data (age, educational level, living arrangements) and clinical data (number of weekly infusions, type of hospital). Expected results: Patients treated with extended-half-life products are expected to report lower treatment burden, higher self-efficacy and better sleep quality, regardless of sociodemographic or clinical factors.
