Objective To examine variation between English regions in the use of surgery (endometrial ablation or hysterectomy) for the treatment of menorrhagia. Design Analysis of Hospital Episodes Statistics (HES) data to produce rates of surgery for English Strategic Health Authorities (SHAs) and Primary Care Trusts (PCTs). Population Women aged between 25 and 59 years who had endometrial ablation or hysterectomy for menorrhagia between April 2003 and March 2006 in English NHS hospitals. Methods Multilevel Poisson regression was used to determine the level of systematic variation in the regional rates of surgery and their association with regional characteristics (deprivation, service provision and mix of surgical procedures). Main outcome measure Age‐standardised annual rates of surgery. Results The English rate of surgery for menorrhagia was 143 procedures per 100 000 women. Surgical rates within SHAs ranged from 52 to 230 procedures per 100 000 women, while rates within PCTs ranged from 20 to 420 procedures per 100 000 women. While, 60% of all procedures were endometrial ablations, the proportion across SHAs varied, ranging from 46% to 75%. Surgery rates were associated with the regional characteristics, but only weakly, and risk adjustment reduced the amount of unexplained variation by <15% at both SHA and PCT levels. Conclusion Regional differences in surgical rates for menorrhagia have persisted despite changes in practice and improved evidence, suggesting there is scope for improving the management of menorrhagia within England.
