Analgesic use and pain coping among patients with haemophilia.

Pain is an important consequence of bleeding episodes in haemophilia. Previous research has included pain frequency and severity among measures of illness-related disability and quality of life in haemophilia, but little systematic evidence exists about analgesic use and pain coping in haemophilia. This paper reports cross-sectional findings from a national survey of patients with severe haemophilia type A and type B. Respondents provided information about pain frequency, pain coping strategies (using the haemophilia-adapted CSQ), use of analgesics and other drugs, and described any concerns they had about their drug use. Participants registered with comprehensive care haemophilia centres did not differ from the rest of the sample on any of the factors recorded. Over one-third of participants expressed concerns about their drug use, the most frequent of which were about dependence on prescribed analgesics. Pain frequency was the most important predictor of analgesic use, but pain coping, and specifically negative thoughts about pain, was associated with concerns about drug use independently of other factors, including analgesic use and pain frequency. Further research will be needed to evaluate possible interventions to promote more effective pain coping in haemophilia, and to examine the possible effects of pain coping on illness outcomes beyond analgesic use, such as well-being and quality of life.
