Abstract

Background. For many women with epilepsy (WWE), decision making about pregnancy is complicated by considerations such as the potential teratogenicity of antiepileptic drugs, offspring risk of epilepsy, seizure occurrence during pregnancy, and the challenges of parenting amidst poorly controlled seizures. Objective. This proof-of-concept, randomized controlled trial aimed to evaluate a decision aid (DA) developed to help WWE decide if they should start or enlarge their families. Methods. Seventy-nine WWE of childbearing age were recruited from Epilepsy Action Australia between October and November 2013 and randomized to receive the intervention (the DA) or not, and to complete a set of questionnaires pre- and post- intervention. The DA, delivered as a PDF booklet, provided balanced evidence-based information about options, risks and benefits, including probabilities; as well as steps for clarifying values and considering options within one’s personal situation. Results. Compared with the control group, the DA group had statistically significant improvements in knowledge about pregnancy and epilepsy (Cohen’s d = 1.24; 95%CI = 0.77 to 1.83) and reduced decisional conflict (Cohen’s d = 0.59; 95%CI = 0.21 to 0.99). Changes in decision self-efficacy, certainty of choice, patient-practitioner communication abilities and value congruence with choice were comparable between the DA and control group. Importantly, women’s decisions about motherhood were not biased towards either direction, and there were no adverse effects on depression or anxiety. All women who received the DA indicated they would recommend it to other WWE. Conclusions. The DA has the potential to serve as a useful support tool for WWE who are considering motherhood. Future research is needed to test the DA in clinical settings with guidance from a health professional. The trial was registered with the Australian New Zealand Clinical Trials Registry (ID ACTRN12613001082796).
