Researchers did this study to design and evaluate a pilot service for PCES.

The study design used was a retrospective analysis of data from two service evaluations. The researchers conducted the study in the gynecology department in a large city in the UK.

We identified all the endometrial samples taken in the city’s gynecology department and estimated the proportion of these with AUB that would be suitable for PCES to design the new service. We analyzed data from the first year of activity to evaluate the new PCES service.

One thousand eight hundred ninety-four endometrial samples were taken in a hospital. An estimated four hundred and twenty-four of these were from patients with AUB who fitted the criteria for PCES. 108 samples were taken by general practitioners. Initial management of these patients was exclusively in primary care in 97.2% of cases; most patients were treated with the Mirena intrauterine system.

The study concluded that most premenopausal patients with AUB could be managed in primary care without referral to the hospital if ES was made available to appropriately trained and supported GPs.
