Abstract

Background: Hemophilia is a rare disorder characterized by spontaneous bleeding, with pain being a critical aspect. However, a systematic assessment of hemophilia-related pain in Portugal has never been conducted.

Objective: To understand the pain experience among Portuguese people with hemophilia (PWH) by describing its prevalence, characteristics, and impact and uncovering intervention needs in the realm of hemophilia-related pain care.

Methods: A cross-sectional observational survey, with age-adapted versions of questions concerning pain, emotional distress, and quality of life, was answered by 104 adults, 21 children/teenagers (10-17 years), and 19 children (1-9 years).

Results: Pain was reported by 82 (78.8%) adults, 16 (76.2%) children/teenagers, and 13 (68.4%) children, with 65 (62.5%), 13 (61.9%), and eight (42.1%) of them reporting pain lasting more than three months, respectively. The mean number of pain locations (SD) was 5.23 (3.95) for adults, 4.13 (3.48) for children/teenagers, and 3.15 (1.99) for children age 1-9 years, with lower limbs pain causing the greatest negative impact. More frequent pain-triggering factors were physical effort/movements (61, 74.4%) for adults and hemarthrosis for younger groups (children/teenagers: 14, 87.5%; children: 9, 69.2%). Bleeds yielded the highest mean pain intensity (adults: M [SD] = 5.67 [2.09]; children/teenagers: M [SD] = 5.69 [2.15]). Adults with pain revealed more anxiety (odds ratio [OR] = 1.698, P = 0.003) and depression (OR = 1.961, P = 0.025) and lower quality of life (OR = 0.928, P = 0.001).

Conclusions: The current findings highlight the high prevalence, duration, and frequency of pain at all ages, its potentially simultaneous acute and chronic nature, its likelihood to affect multiple locations concurrently, and its detrimental impact. Important insights concerning intervention needs are presented, ultimately contributing to the improvement of hemophilia-related pain management and patient care.
