Abstract 17875: Translating 3D Printing into Clinical Practice: Do Patient-Specific Models Aid in Communicating with Parents of Children with Congenital Heart Disease?
Introduction: Communication in medical consultations is recognised as an important factor in optimising patient satisfaction and health outcomes. Patient-specific (PS) plastic models of congenital heart lesions may offer benefits for education and communication purposes. This study aimed to quantitatively test the translational potential of PS models in a systematic manner.
Methods: Parents of children with congenital heart defects (n=97), matched for age, sex and level of education, were divided into Group I (n=52) for normal consultations/follow-up visits, and Group II (n=45) where PS models generated from magnetic resonance imaging and printed in white nylon with rapid prototyping machine model were additionally used. Participants and cardiologists completed rating scales (scored from 0-10) to assess parents’ knowledge of their child’s condition before and after the consultation and to provide feedback on any tools used, including the 3D model.
Results: Clinicians reported that the models were very useful (8.8±1.1/10), encouraged parent interaction (9.1±1.4/10), and did not lengthen consultation (93% cases), although these lasted 5 minutes longer (p=0.02). Parents rated PS models as very useful (9.5±0.7/10) and more informative than medical images, with 73% explicitly asking to keep their model. Parents in both groups equally felt their understanding improved following their visit, although when their questionnaires were rated blindly by two cardiologists only 5 participants per group were actually found to demonstrate improved understanding. In 40% of cases the cardiologists were not able to gather even the primary diagnosis based on the information provided by parents after their consultation.
Conclusions: Patients’ parents and clinicians found PS models to be useful communication tools, although parents’ understanding appears to be mainly related to their prior level of knowledge. Clinicians found PS models useful in explaining congenital heart defects and encouraging parent interaction. Use of such a modality during the first interactions with parents may have benefits for improving parents’ participation in their child’s management.
