When the clinician who ordered the imaging that led to randomization receives the test results, a pre-checked referral order to gynecologic oncology for surgical evaluation will appear in the EHR alongside a brief educational explanation. This will constitute the opt-out default referral order (Figure 3). Clinicians will have the option to unclick the referral to opt out and will be asked to indicate the reason from a pre-populated list of choices; if they do not opt out, the referral to gynecologic oncology will proceed. Imaging findings and referral will be communicated to the patient in keeping with the clinician's usual practice. In keeping with routine practice, referred patients will be contacted by gynecologic oncology's new patient coordinators within 72 hours and offered an appointment within 2 weeks at their preferred location.

Clinicians will receive imaging reports per usual practice (i.e., imaging reports that include O-RADS score with recommendation for gynecologic oncology referral in the report) and can place referral through the usual EHR-based ordering system. If referred, patients will be contacted and scheduled as described above.
