Objective:

Pain and functional impairment resulting from joint disease in patients with hemophilia (PWH) may impact emotional well-being, resulting in consistent reports of anxiety/depression. The P-FiQ study formally evaluated patient-reported anxiety/depression symptoms and treatment as well as responses to standardized patient-reported outcomes (PROs), and evaluated reliability, validity, and consistency of responses.

Methods:

At a comprehensive care visit, adult male PWH with a history of joint bleeding or pain completed a hemophilia history and 3 patient-reported outcomes (PROs) assessing anxiety/depression and quality of life (QoL): EQ-5D-5L, Brief Pain Inventory (BPI), and SF-36v2. PROs were assessed for reliability, consistency, and correlation with factors including patient-reported characteristics.

Summary:

A total of 381 PWH (median age, 34 years) were enrolled in P-FiQ; 77% had hemophilia A, 23% had hemophilia B, and 9% had inhibitors. Fewer than half (44%) were currently receiving routine infusions to prevent bleeding. More than half were employed full-time (53%), and 65% were married or had a long-term partner. Depression was reported by 19% and anxiety by 14%. On the EQ-5D-5L anxiety/depression item, 43% reported feeling anxious or depressed “today.” On BPI, most participants indicated that pain interfered in the previous week with mood, sleep, and enjoyment of life, and more than half (54%) indicated interference with relations with other people. On SF-36v2 (range 0- 100, higher scores indicate better QoL), median mental health summary score was 50.7; subdomains were similar (vitality, 49.0; social functioning, 45.6; role emotional, 55.9; mental health, 52.8). Emotional problems resulted in reduced time spent on work/activities (40%) and accomplishing less than they would like (47%). More than half (55%) had felt downhearted or depressed, and a large majority (93%) had felt tired in the past 4 weeks. Sixty percent of participants indicated that their physical or emotional problems had interfered with their normal social activities with family, friends, and other contacts. Similar items across PROs correlated with one another, and PRO scores (EQ-5D-5L anxiety/depression, SF-36 mental health) were significantly (P<0.05) correlated with self-reported anxiety/depression.

Conclusion:

Anxiety and depression in adults with hemophilia have been consistently reported in other studies and were identified in P-FiQ by self-report and across several PRO instruments. Emotional problems were reported to interfere with normal social activities and productivity. While the unmet need to address mental health in PWH has received increased recognition, it is not typically assessed formally. When compared with pain, management strategies and/or referral relationships may also not be as formally established. The findings presented here highlight the potential value of simple screening tools (eg, EQ-5D-5L) and opportunities to encourage patient dialogue about mental health within the comprehensive care setting and in referral networks.
