RESUMEN
Collecting and interpreting self-reported outcomes among people with hemophilia A supports the understanding of the burden of the disease and its treatment to improve holistic care. However, in Colombia, this information is limited. Therefore, this study aimed to describe the knowledge, perception and burden of hemophilia A from the patients' perspective. A cross-sectional study was conducted in the context of a hemophilia educational bootcamp held from November 29th to December 1st, 2019, in Medellin, Colombia. The bootcamp was organized by a hemophilia patient association responsible for contacting and inviting patients with hemophilia A (PwHA). Information on patients' health beliefs, treatment experiences, and health-related quality of life (HRQoL) was obtained through focus groups, individual interviews and the Patient Reported Outcomes, Burdens and Experiences (PROBE) questionnaire. A total of 25 moderate or severe PwHA were enrolled in this study and completed the PROBE questionnaire. Acute pain was the most frequently reported symptom, with 88% of the patients reporting the use of pain medication. Difficulty with activities of daily living was reported by 48%. Furthermore, 52% reported having more than 2 spontaneous bleeding events in the last year. Treatment was administered at home for 72% of patients, with regular prophylaxis as the most common treatment regimen. In terms of overall HRQoL, the median EQ-5D VAS score was 80 (IQR: 50-100). PwHA in Colombia still suffer from disease complications related to bleeding events, pain and disability that affect their HRQoL, which highlights the need to develop patient-centered initiatives to improve the wellness of this population.
