Change of Practice Patterns Following an Educational Comment on Reports of Benign-Appearing Endometrial Cells in Papanicolaou Tests

Abstract

Abstract Objectives Since the publication of our study demonstrating high negative predictive values (>99% for women in their 40s) of benign-appearing endometrial cells (nEMCs), we have begun to include an educational comment in Papanicolaou (Pap) test reports with nEMCs that recommends routine periodic screening for asymptomatic premenopausal women (APW). The current study evaluated how the inclusion of this comment has affected clinical practice patterns at our institution. Methods The 2017 to 2019 database identified 175 reports containing the educational comment in women aged 45 to 54 years with a follow-up time of 11 to 37 months. Data, including age, menopause status, symptoms, imaging, and outcome, were collected. The procedure rate and the impact of clinical modifiers were assessed. Results Thirty-seven (20.6%) patients had biopsies within 6 months, which decreased from 48.1% as we previously reported. All nine (5%) APW with biopsies triggered only by nEMCs had benign histopathology. The remaining 28 biopsied patients had abnormal bleeding or a thickened endometrium, or they were postmenopausal, including a 53-year-old patient with complex atypical hyperplasia. None of the 138 patients with conservative follow-up developed atypical/malignant lesions. Conclusions A qualifying educational note included in Pap reports significantly reduced follow-up biopsies in APW. Optimal follow-up of nEMCs should be based on relevant clinical modifiers.
