Standard of care includes discharge instructions from one of our IVF nurses regarding medications and timing of follow-up, at which point patients are told what day they need to return for their pregnancy test. Patients have access to phone numbers for their IVF nurses and physicians, as well as information about how to contact the social workers if additional support is needed. They also are provided the emergency phone numbers for after-hour calls to the fellow on call. However, during the time between the embryo transfer and the pregnancy test, the current standard of care is that contact between the patient and our team is patient-initiated.

The intervention consisted of two phone calls from an IVF social worker during the time between embryo transfer and pregnancy test. The first phone call occurred between days 2-4 after transfer and the second phone call occurred between days 5 and 9 after embryo transfer. Standard language for introductions to phone calls and for voice mails was established prior to the start of the study.

Phone calls to offer emotional support

The perceived stress scale is a validated instrument to assess psychological stress

Exit questionnaires were administered 10 days after transfer to assess patient perceptions of the study.
