Prevalence and perceptions of pain in people with haemophilia: A UK study

Abstract

AbstractIntroductionJoint bleeds in haemophilia cause destruction of articular structures, impaired function and pain. Up to 70% of people with haemophilia (PWH) report chronic pain. Little is known about the pain experiences in PWH in the UK.AimTo identify prevalence and perceptions of pain among PWH living in the UK.MethodsA cross‐sectional, non‐interventional survey study conducted among PWH (all severities). The survey incorporated elements from validated tools (EQ‐5D; EQ‐VAS) and was distributed via participating treatment centres.ResultsFive hundred and ninety‐nine PWH responded, 91% aged > 18. 81% used factor prophylactically or on demand. More pain was reported by those treated on demand versus prophylaxis particularly in those who reported daily pain. 65% reported ‘problem joints’ based on individual impact rather than medically defined ‘target joints’, 2/3 reported multiple joint issues. The ankle was most commonly affected. 59% reported frequent pain, with 56% aware of pain constantly or most of the time and were more likely to report less favourable EQ‐5D or EQ‐VAS scores (p < .001). Pain frequency/awareness was consistent across all severities. Most discussed pain with care teams, 31% only when asked; 25% did not discuss it. Pain discussions resulted in physiotherapy referral (63%) analgesia prescription (48%), and a minority specialist pain referral (9%). Most felt well supported with regard to their pain, but 70% reported learning to live with it.ConclusionPain affects PWH of all ages and severities even in a well‐resourced country significantly impacting quality of life. Clinicians must be more aware of chronic pain in PWH. Biopsychosocial approaches to pain assessment and management are recommended.
