Brief summary

This study aims to develop a visual aid tool for induction education informed by the experiences and needs of historically marginalized pregnant women, as well as determine the impact of the patient-informed visual aid on patient knowledge, satisfaction, and trust in physicians regarding induction methods.

Detailed description

This is a multi-phased study of patients undergoing IOL. Only the second phase of the study will be detailed in this protocol, as this will be the RCT portion of the study's design. We will test the efficacy of the visual aid by conducting a randomized trial of routine counseling versus counseling with the use of a visual aid (informed by patient interviews in the first phase) at the time of admission for IOL and studying the effect of the visual aid on patient knowledge, trust in providers, and satisfaction.
