Impact of 3D-printed anatomical models on short-term clinical outcomes: a randomized controlled trial

Jan Witowski jwitos@gmail.com

Abstract

Despite the stable growth of 3D printing and its implementations in medicine, there is still no consensus whether this technology has an impact on clinical decisions and, if it does, how significant it is. The goal of our study is to conduct a randomized controlled trial (RCT) evaluating the usefulness of patient-specific 3D models in surgical environments. Liver and vasculature models are developed before elective procedures in different departments of Jagiellonian University. Clinical outcomes will be compared to prospective databases of patients. Data regarding patients' education and surgeons' satisfaction will be gathered and statistically analyzed.

During the Medicine X conference, we will present the methodology of our trial, fabrication technique, workflow and, most importantly, early results of the trial.

Our research team believes that rapid prototyping has a chance to be implemented and used on a daily basis, but only if we provide quantitative, clinically and statistically significant results. The low-cost approach, utilized in our RCT, is supposed to be another major supportive factor when planning in-house implementation of additive manufacturing. Our team has experience creating unique, cost-effective 3D printing methods.
