About

The purpose of this pilot study is to examine the feasibility of conducting a multi-site randomized controlled trial whose aim will be to evaluate the effectiveness of a Patient Decision Aid (PDA) for antidepressant use in pregnancy.

Full description

Depression in pregnancy is common, affecting up to 10% of women and represents serious risk to mother and infant. Unfortunately, antidepressant medication, a first-line treatment for depression in pregnancy, also comes with risks, making this a complex decision. Clinical care appears to be insufficient for ensuring that women make decisions that are consistent with their own values and with which they feel satisfied. Patient decision support tools can address such barriers. We have created a patient decision aid (PDA) that has the potential to improve the decision-making process for women regarding antidepressant use in pregnancy in conjunction with clinical care. The overall objective of this project is to inform the development of a larger, international RCT to assess the efficacy of our PDA for antidepressant use in pregnancy. To achieve this objective, we will assess the feasibility of our clinical trial protocol to evaluate the PDA and determine the preliminary effect size for a larger multi-site efficacy study. The primary outcome for this pilot study is the feasibility of conducting a large randomized controlled trial to evaluate the efficacy of the PDA. This includes feasibility (how well the trial protocol can be implemented), acceptability (usability and tolerability of the intervention) and adherence (the degree to which the trial protocol is followed). We hypothesize that our protocol will be feasible, that the PDA will have a high degree of acceptability, and that adherence to the protocol will be high.

Enrollment: 100 patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Are females aged >18 years old, and
2. Are either planning a pregnancy OR are <30 weeks gestation at enrollment, and
3. Have been offered to start or continue SSRI or SNRI anti-depressant medication as a treatment option for depression by their clinical provider at one of the study sites, and
4. Have moderate-to-high decisional conflict (score of >25 on the Decisional Conflict Scale)

Exclusion criteria

1. Have had alcohol or substance abuse or dependence in the previous 12 months, or
2. Have active suicidal ideation or psychosis, or
3. Are incapable of consenting to participation, or
4. Have any major obstetrical complications or fetal cardiac anomaly in the current or in a past pregnancy (as this changes the risk/benefit ratio discussion in regards to antidepressant use), or
5. Are unable to read or unable to speak or understand English and do not have someone that can read the PDA to them, or
6. Have a visual impairment that would prevent them from being able to view the website.

Trial design

Primary purpose: Health Services Research

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

100 participants in 2 patient groups, including a placebo group

Standard Resource Sheet

Placebo Comparator group

Description:

Women allocated to the control intervention will login to the study website and receive a printable PDF containing references to standard published information on antidepressant use in pregnancy. This ensures women have access to accurate information on the benefits and risks of antidepressant medication in pregnancy (even though they will not receive the PDA).

Treatment:

Behavioral: Standard Resource Sheet

Electronic Patient Decision Aid

Active Comparator group

Description:

The electronic Patient Decision Aid (PDA) is an interactive website with 3 main sections: 1. Evidence-based information on (a) depression in pregnancy, (b) each treatment option and procedure; 2. (a) Evidence-based information on the risks and benefits of both untreated depression and antidepressant treatment, (b) exercises to help women determine which risks and benefits are most important to them; and 3. A summary section that outlines the information reviewed and which benefits and risks they deemed most important. At the end of the PDA, women allocated to this intervention will ALSO receive the standard resource sheet which is being used as the placebo comparator.
