Evaluation of a Decision Aid for Early Pregnancy Loss: a Pilot RCT Study

Early pregnancy loss (EPL) or miscarriage is a common problem occurring in 15-20% of pregnancies. EPL can safely be managed surgically, medically, or expectantly; patient preferences, together with provider recommendations, should be used to guide treatment decisions. The three management options differ substantially experientially for patients. Previous literature has shown that patients have preferences for treatment and higher satisfaction when treated according to their preferences. Decision aids provide individualized information to help patients clarify their priorities and personal values. There is good evidence that decision aids compared to usual care resulted in greater knowledge, more realistic expectations, lower decisional conflict relating to feeling informed, more active decision making, less people remaining undecided, and greater effect agreement on value and choice. Despite this, there is limited research on the extent of decisional conflict experienced by women undergoing treatment for EPL, or the effect of decision aids on decisional conflict. Furthermore, only a few decision aid tools are publicly available for this indication. The Healthwise decision aid tool receives high scores by the International Patient Decision Aid Standards Scale, and is readily available to patients within the clinical site's electronic medical record.

The investigators propose a pilot randomized control trial, enrolling 50 participants with EPL. The study will measure baseline decisional conflict, and randomize participants to counseling with or without the decision aid. The investigators intend to study the Decisional Conflict Scale at baseline and after counseling, knowledge scores, Decision Regret and the 9-item Shared Decision Making Questionnaire (SDM-Q9) after counseling. Study data can be used to inform future research and to identify patients with predictors for high decisional conflict. This study is the first step towards validation of a high-quality decision aid tool for patients undergoing EPL management. It will also be the first study to report on decisional conflict and regret in patients with early pregnancy loss.
