British consultant rheumatologists' perceptions about the hypermobility syndrome: a national survey.

Three hundred and nineteen UK-based consultant rheumatologists, members of the British Society for Rheumatology (a response rate of 76%), responded to a questionnaire concerning their perceptions of the (benign joint) hypermobility syndrome (HMS). The questions were wide-ranging and covered the nature of the condition, its clinic prevalence, criteria for diagnosis, the efficacy of chosen treatments, the impact of the syndrome on affected individuals and the contribution that it makes to the overall burden of rheumatic disease morbidity. Ninety-two per cent of the respondents believed in the HMS as a distinct clinical entity but only 39% accepted it as a distinct pathological entity. Only 42% were prepared to comment on whether the HMS and Ehlers-Danlos syndrome, hypermobility type (formerly EDS type III) were one and the same entity. There was striking variability in estimated clinic prevalence and no consensus about the diagnostic criteria being used. There was little enthusiasm for treatments currently available. Nearly one-half of the respondents were sceptical about a significant impact of the HMS on people's lives and three-quarters about a significant contribution to the overall burden of rheumatic disease. There was little sign of awareness of findings in recent published studies. It seems unlikely, therefore, that evidence-based medicine is being practised in this area of rheumatology. An unexpected finding was a refreshing enthusiasm for joining regional interest groups on hypermobility (25% of all UK consultants expressed interest).
