Summary. To describe the study design, procedures and baseline characteristics of the Haemophilia Utilization Group Study – Part Va (HUGS Va), a US multi‐center observational study evaluating the cost of care and burden of illness in persons with factor VIII deficiency. Patients with factor VIII level ≤30%, age 2–64 years, receiving treatment at one of six federally supported haemophilia treatment centres (HTCs) were enrolled in the study. Participants completed an initial interview including questions on socio‐demographical characteristics, health insurance status, co‐morbidities, access to care, haemophilia treatment regimen, factor utilization, self‐reported joint pain and motion limitation and health‐related quality of life. A periodic follow‐up survey collected data regarding time lost from usual activities, disability days, health care utilization and outcomes of care. HTC clinicians documented participants’ baseline clinical characteristics and pharmacy dispensing records for 2 years. Between July 2005 and July 2007, 329 participants were enrolled. Average age was 9.7 years for children and 33.5 years for adults; two‐thirds had severe haemophilia. The distributions of age, marital status, education level and barriers to haemophilia care were relatively consistent across haemophilic severity categories. Differences were found in participants’ employment status, insurance status and income. Overall, children with haemophilia had quality of life scores comparable to healthy counterparts. Adults had significantly lower physical functioning than the general US population. As one of the largest economic studies of haemophilia care, HUGS Va will provide detailed information regarding the burden of illness and health care utilization in the US haemophilia A population.
