Clinical Trial Summary
This will be a randomized controlled trial to compare if physician contact within the period
from embryo transfer to serum pregnancy test decreases anxiety levels for first-time IVF
patients.
Description:
Overview This will be a randomized controlled trial to compare if physician contact within
the period from embryo transfer to first pregnancy test decreases anxiety levels for
first-time IVF patients.
Methods Study participation will not influence any element of IVF treatment, and all patients
will be receiving the standard of care at Boston IVF. Potential participants will be
identified by a member of the research team, who will review the appointment log and medical
records to ensure eligibility. Participants who meet eligibility criteria will receive an
email introduction to the study on the first stimulation day of the cycle and participants
will be asked if interested in participating. Interested participants can click a secure
REDCap link to learn more about that study. Participants who agree to participate will be
directed via a unique link for each participant to a REDCap survey to complete a baseline
questionnaire prior to the first ultrasound monitoring (T1), which is normally day 3 to 6 of
IVF stimulation. Participants that complete the baseline survey are consenting for the study.
Baseline demographic data will be obtained from the electronic medical record including: age,
race, education level, partner status, height, weight, gravidity, and parity. Baseline
clinical data, including anti-mullerian hormone and day 3 follicle stimulating hormone
levels, will be obtained from the electronic medical record. The baseline survey will include
demographic questions, the state-trait anxiety inventory (STAI), and the Hospital Anxiety and
Depression Scale (HADS). STAI and HADS are two validated surveys used widely when examining
anxiety in patients. The STAI is comprised of the trait and state questions. After
stimulation day 3, a reminder email will be sent to eligible participants via REDCap to
introduce the study again with a follow up phone call on stimulation day 4, if needed. Given
the quick turnaround time from stimulation day 1 to first ultrasound monitoring (stimulation
day 3 to 6), the additional email/phone contact schedule is necessary. If participants do not
complete the baseline survey in entirety, participants will not be eligible for
randomization. Participants will need to complete the survey in one sitting. Randomization
will only occur if participants have an embryo transfer and complete the baseline survey. If
selected to the intervention arm, participants will be called by one physician 3 to 4 days
after the embryo transfer. Participants will be informed that the physician contact is not
the participants specific doctor of record and that the physician contact will not be able to
answer specific questions about the participants treatment cycle.
All participants that have an embryo transfer (fresh or frozen) will have a scheduled serum
beta-hCG 10-12 days after the date of transfer. Eight days after the transfer (T2),
participants will receive a second survey that will only include the STAI - state and HADS to
be completed prior to the first serum beta-hCG. If participants have not started the survey
by 9 days after the transfer, the participant will receive a reminder email on stimulation
day 9 in the morning followed by a phone call on stimulation day 9 in the evening if needed
for a reminder to complete the survey. The participant has the option to withdraw from the
study at any time by notifying the research team by email or phone.
Intervention Participants will receive routine care or an approximately five-minute phone
call from a physician 3 to 4 days after a fresh or frozen embryo transfer. The physician will
state they are a part of the research team. For participants that do not answer the phone, a
message will be left stating the participant will receive another phone call that same day
and once more the following day if the participant does not answer on the second attempt. The
phone call will follow scripted questions and utilize scripted phrases to help minimize
variation.
Randomization Participants undergoing a fresh embryo transfer or planned frozen embryo
transfer/PGT-A are eligible for inclusion in the study. Participants will be block-randomized
by type of transfer to ensure balance between the intervention and control groups. The
randomization scheme will be generated via REDCap. If participants are randomized to the
intervention arm, participants will know this only if the participant receives a physician
phone call during the waiting period after embryo transfers. All participants, regardless of
transfer type, will be randomized only after participants have an embryo transfer.
Sample Size Justification The sample size calculation is based on data from a prior study
that evaluated stress throughout the course of a IVF cycle using the STAI. The mean STAI-S in
the infertility population ranges from 33-50, with Turner et al. reporting a mean STAI-S
score of 40 ± 12. Assuming that the mean STAI-S score in the control group will be 40 ± 12 at
the second time point, the investigators hypothesize that the mean STAI-S at this point in
the intervention group will decrease to 35 ± 12. In order to achieve 80% power to detect the
specified difference using a two-sided alpha of 0.05, the investigators will need 91
evaluable participants per arm. The Investigators anticipate that approximately 15% of
participants will not complete the second survey, and the investigators will inflate the
sample size by another 15% to account for a non-normal distribution. Thus, the investigators
aim to randomize 121 participants per arm for a total of 242 participants.
Data Analysis Descriptive data will be presented as the proportion, mean with standard
deviation, or median with interquartile range. Comparisons will be made using the chi-square
or Fisher's exact test for categorical variables and parametric or non-parametric tests for
continuous variables based on data distribution. All data will be analyzed with SAS 9.4 (SAS
Institute Inc., Cary, NC, USA). All tests will be two sided and a P value <0.05 will be
required to confer significance.
