After the recent publication of the CODA Trial comparing antibiotics and surgery for acute appendicitis, the investigators developed a comprehensive decision support tool. This tool will help patients understand the risks and benefits of each treatment and make a treatment decision. This study is an online randomized field test comparing the decision support tool to a control infographic and assessing it's affect on decisional outcomes, such as decisional conflict.
