General practitioners use of hormone-replacement therapy in Yorkshire.

Questionnaires were sent to 1000 general practitioners (GPs) in the Yorkshire Region to obtain information about their approach to the use of hormone-replacement therapy (HRT) in the menopause. A total of 310 GPs returned completed questionnaires. These showed widely varying views. The majority of GPs estimated that less than 10% of their perimenopausal patients had taken HRT at some time. There was confusion about the reported effects of HRT, on the risks of endometrial carcinoma and on ischaemic heart disease. Thus, while 86% correctly judged that HRT was protective against osteoporosis, 70% concluded against prevailing opinion that combined preparations increase the risk of endometrial cancer. In contrast to the bulk of evidence, nearly 50% of respondents believed that the risk of ischaemic heart disease was also increased by HRT. A number of GPs considered lack of an authoritive lead from epidemiology to be their greatest difficulty in forming an opinion on the desirability of HRT. The general approach to HRT was cautious in respect of both the frequency and the duration of the therapy. Less than a quarter of the GPs were sympathetic to the idea of prophylactic HRT and only 7% routinely discussed this possibility with menopausal patients, while the majority felt that the duration of therapy should be limited to 2 years or less. Most respondents also showed intuitive resistance to the idea of 'mass therapy' at the menopause and expressed concern at the idea of 'interfering with nature'.
