Clinician Nudge to Referral of Adnexal Masses to Gynecologic Oncology

The goal of this study is to test the effectiveness of clinician nudges on referrals to gynecologic oncology in patients with suspected ovarian cancer. The primary outcome will be whether or not patients were referred to gynecologic oncology within 14 days of their abnormal imaging results. Secondary and exploratory outcomes are whether the gynecologic visit occurred within 60 days of abnormal imaging and the time from abnormal imaging results to gynecologic oncology visit.

Inclusion Criteria: * Eligible clinicians include physicians, physician assistants, and nurse practitioners with eligible patient encounters at sites included in the trial during the study. * Eligible patient encounters are defined as an emergency room visit, inpatient hospitalization, or outpatient visit during the study period where the patient had associated imaging with suspected ovarian cancer (O-RADS 4 or 5 lesion), identified with the EHR-based tool described above. Exclusion Criteria: * Known diagnosis of ovarian cancer. * Imaging ordered by gynecologic oncologist.
