Abstract
BACKGROUND. Hormone replacement therapy is used for the relief of menopausal symptoms. In the United Kingdom, guidelines have been developed for the use of hormone replacement therapy in the prevention of osteoporosis, and in the United States of America its use has also been recommended for cardiovascular disease prevention. However, compliance has been found to be a problem, and rates of prescribing vary between general practitioners. AIM. This study set out to describe the prescribing of hormone replacement therapy in one general practice, to enable doctors to plan future prescribing and promotion of hormone replacement therapy, taking into account constraints on its use. METHOD. The patient records of users of hormone replacement therapy were examined to collect data on menopausal status, reason for use, length of use, breaks from therapy and reasons for stopping therapy. Women with a history of hysterectomy and with risk factors for osteoporosis were identified from the practice morbidity register. Their use of hormone replacement therapy was recorded. RESULTS. Of women aged 40-59 years on the practice list, 348 were taking hormone replacement therapy (20%). Of 107 women aged under 52 years who had had a hysterectomy and bilateral oophorectomy 76 were taking therapy (71%). Of 158 women under the age of 52 years who had had a hysterectomy with preservation of the ovaries 39 were taking therapy (25%). Among women taking hormone replacement therapy for the relief of menopausal symptoms, the highest rate of use was among those aged 50-54 years where 93 were on therapy (24% of women in that age group in the practice). Twenty out of 47 women with a recorded risk factor for osteoporosis were taking therapy. More than three quarters of women using hormone replacement therapy appeared to be taking it continuously. CONCLUSION. The uptake of hormone replacement therapy was found to be high for women with a surgical menopause, the group most easily identifiable as at risk of osteoporosis. Women who decided to take therapy appeared to take it continuously, and therefore effectively for prevention. Rate of uptake, rather than compliance, is more likely to constrain its use in prevention.
