Objective:
Hemophilia is a congenital deficiency in a clotting factor resulting in a propensity for severe and disabling bleeds. Joint bleeds can lead to disabling arthropathy and past contamination of blood products resulted in an epidemic of HIV and hepatitis. We hypothesize that these issues may result in declines in quality of life, psychosocial well-being, and socialization (integration into society) and that socialization correlates with health-related quality of life (HR-QoL).
Methods:
We developed a socialization survey and interview for patients age >20 with hemophilia A (n=14) or B (n=4) and their spouses/significant others (SSOs) (n=9). The interviews were analyzed using PROMIS (patient-reported outcomes measurement information system-29) domains. Patients completed surveys in health-related quality of life measures including both A36 Hemofilia-QoL and WHOQOL-BREF. Patients were also scored according to the Colorado Joint Assessment Scale and Karnofsky Performance Scale. IRB approval and informed consent were obtained.
Results:
19 patients were enrolled (ages 24-78), one withdrew. Nine patients had severe hemophilia, 5 had moderate disease, and 4 were mild. Four patients did not have SSOs (22%, 90% CI: [8%; 44%]); these included two severe and two moderate patients, one with HIV, and three with hepatitis C. Five SSOs declined participation. For the WHOQOL-BREF, patients reported overall quality of life in the physical domain an average score of 60 (range 13-94), 66 (31-100) in the psychological domain, 66 (31-100) in the social relationship domain, and 81 (44-100) in the environmental domain, all standardized 0-100. For the A36 Hemofilia-QOL, the median score was 94 (range 43-132) out of 144 (totaling physical health, daily activities, joint damage, pain, treatment satisfaction, treatment difficulties, emotional functioning, mental health, and relationships and social activities). Colorado Joint Assessment Scale-QOL provided scores of 6.1 out of 19 for ankles without gait and 8.3 out of 21 with gait, 4.2 for knees without gait, 6.3 with gait, and 3.6 for elbows. Analysis of interviews reflects social roles and social support as common domains in patients, whereas anxiety and anger predominated for SSOs.
Conclusions:
This study employed established instruments as well as novel questionnaires and interview structures, although the latter have not been validated. Analysis points toward patient concerns regarding their social roles while SSOs expressed higher levels of anxiety and anger compared to patients. Both health-related-QoL and disease severity appear to be associated with social support domains of socialization. Patients with more severe disease may be less likely to have SSOs.
