Management of menorrhagia in primary care---impact on referral and hysterectomy: data from the Somerset Morbidity Project

Abstract

OBJECTIVE To investigate the management of menorrhagia in primary care and its impact on referral and hysterectomy rates. DESIGN Prospective observational study. SETTING 11 general practices from the Somerset Morbidity Project. SUBJECTS 885 women consulting their general practitioner with menorrhagia over four years. MAIN OUTCOME MEASURES Proportions of these women investigated and treated with drugs in primary care, referred to a gynaecologist and undergoing operative procedures. The relation between investigation and prescribing in primary care and referral to and surgery in secondary care. RESULTS Less than half of women had a vaginal examination (42%, 95% CI 39% to 45%), or a full blood count (39%, 95% CI 36% to 43%). Almost a quarter of women, 23% (95% CI 20% to 26%), received no drugs and 37% (95% CI 34% to 40%) received norethisterone. Over a third, 38% (95% CI 34% to 40%), of women were referred, and once referred 43% (95% CI 38% to 48%) of women were operated on. Women referred to a gynaecologist were significantly more likely to have received tranexamic acid and/or mefenamic acid in primary care (χ²=16.4, df=1, pCONCLUSIONS Substantial differences in management exist between practices when investigating and prescribing for menorrhagia in primary care. Rates of prescribing of effective medical treatment remain low. The decision to refer a woman impacts markedly on her chances of subsequently being operated on. Effective management in primary care may not reduce referral or hysterectomy rates.
