The goal of this study was to determine a) if a follow-up email to selected patients who had an initial consult with an infertility specialist, but did not return for a second visit, would change return to care behavior and b) why patients had not returned. Controlled prospective trial. From July 2017 to March 2018 all patients who had attended an initial visit with an infertility specialist at the clinic, but had not returned for at least three months were selected to receive a follow up email. Those selected for an email excluded patients who we knew had achieved a pregnancy, already had a plan for treatment, had visited for an egg freeze and all LGTPQ patients. The email asked if the patient had any questions about that visit, offered support to the patient and included contact information for the patient liaison sending the email. The email also asked each participant to indicate why they had not returned and were provided 4 options and an opportunity to write in a response. From April 2018 to December 2018 no emails were sent to patients. No other change of patient contact practice was initiated during the trial period. All patients were then followed for 11 months after their initial visit to observe return to care behavior. A total of 647 patients were selected to be sent 301 emails (Group 1) and 657 did not receive an email (Group 2). Forty-one percent of the patients in Group 1 returned to care, compared to 32% who did not (Group 2) (P<.0014). Of the Group 1 patients 116 replied (38.5%). For those who gave a reason why they hadn’t returned, 32% of the respondents conceived on their own, 3% transferred care to another infertility center, 31% were taking a break/holding off from treatment, and 3% were unhappy with their care at the first visit. A total of 31% made a follow-up appointment. A simple follow-up email sent to patients who had an initial visit with an infertility specialist but did not return to the clinic within three months was associated with a significant increase in return to care when compared to patients who did not receive an email.
